    [0001] The invention relates to a connector terminal comprising a female connector terminal, and a male connector terminal in which the female connector terminal is mounted.
    [0002] A male connector terminal of a male electrical connector is mounted in a female connector terminal of a female electrical connector to thereby electrically connect thereto. A female connector terminal is adapted to include a sheath portion into which is inserted a tongue portion of a male connector terminal which is in the form of a needle. By being inserted into a sheath portion, a tongue portion of a male connector terminal engages a flat spring housed in the sheath portion. When a tongue portion is inserted into or removed from a sheath portion, the tongue portion slides relative to a flat spring. For example, a tongue portion performs a sliding movement on a flat contact surface thereof with a flat contact surface of the flat spring, resulting in the generation of significant friction. Since significant friction is generated in an electrical connector having a large number of terminals, a tab portion must be inserted into or removed from a sheath portion with excessive force. Therefore, this is made difficult when a male electrical connector and a female electrical connector are inserted into or removed from each other. In addition, since a tongue portion and a flat spring slide over one another through contact surfaces thereof, the contact surfaces can be eroded. In order to solve this problem, Japanese Patent Application Publication Number 2007-18803 has suggested a connector in which the contact surfaces are difficult to erode, maintaining sufficient reliability for electrical contact between the male and female connector terminals. Figure 15 illustrates a portion of a connector 1010 suggested in the publication identified above. The illustrated connector 1010 includes a male terminal 1022, and a female terminal 1014 in which the male terminal 1022 is inserted. The male terminal 1022 has a corrugated section viewed in a direction in which the male terminal 1022 is inserted into the female terminal 1014. The female terminal 1014 is forced to the male terminal 1022 so as to thereby contact the male terminal 1022. two points. The connector 1010 having the structure as mentioned above is not accompanied by a faulty contact between the female terminal 1014 and the male terminal 1022, even if the female terminal 1014 was not forced to the male terminal 1022 with excessive force. In the connector 1010 shown in Fig. 15, since the male terminal 1022 is of the wavy form, the male terminal 1022 contacts the female terminal 1014 at two points. However, if the male terminal 1022 deviates horizontally from the female terminal 1014, protrusions of the corrugations of the male terminal 1022 are also deflected, with the result that only a protrusion of the male terminal 1022 comes into contact. with the female terminal 1014. Thus, it is not possible to keep a stability in the contact between the male terminal 1022 and the female terminal 1014, and a reliability of contact can not be ensured between the male terminal 1022 and the female terminal 1014.
    [0003] Due to the aforementioned problems in the conventional connector, it is an object of the present invention to provide a connector terminal capable of reducing a force with which connector terminals are mounted in or removed from one of the other, and increasing reliability of contact between the connector terminals. In one aspect of the present invention there is provided a connector terminal comprising a first connector terminal and a second connector terminal to be mounted in the first connector terminal, the first connector terminal comprising a flat spring engaging the connector terminal. a certain area of the second connector terminal, the certain area including a free end of the second connector terminal, and a terminal body including a pair of side walls between which the flat spring is disposed, the second connector terminal having a rectangular cross-section, the second connector terminal comprising two or more first projections in the one area on one of the two facing surfaces thereof, the first two or more projections each extending in a first direction in which the second connector terminal is mounted in the first connector terminal, at least two first illies among the first projections coming into contact with the flat spring between the side walls. In the connector terminal according to the present invention, the second connector terminal includes in the area at least two first projections which each extend in a first direction in which the second connector terminal is mounted in the first connector terminal. It is therefore possible to reduce a force required to insert the second connector terminal into and remove the second connector terminal from the first connector terminal. Furthermore, since at least two first projections remain in contact with the flat spring, the first and second connector terminals can maintain a stable contact with each other even if the certain area of the second connector terminal moves in a sheath portion between the side walls. It is preferable that the terminal body comprises a ceiling portion and a floor portion each connecting the side walls to each other, the second connector terminal comprising in the certain area (211) at least a second projection from in contact with the ceiling portion and extending in the first direction, the second projection being formed on the other surface of the two surfaces. By designing the second connector terminal to contact at a certain area thereof not only with the flat spring, but also with a ceiling portion, a contact area at which the second connector terminal comes from in contact with the first connector terminal is increased, and therefore a force necessary to insert the second connector terminal into and remove the second connector terminal of the first connector terminal is increased. However, since the second connector terminal is formed in the area with the second projection on a surface through which the second connector terminal comes into contact with the ceiling, it is possible to reduce a force necessary to insert the second connector terminal in and removing the second connector terminal of the first connector terminal.
    [0004] It is preferred that the flat spring comprises an enlarged portion engaging the at least two first projections. By designing the flat spring to include an enlarged portion, the number of first projections coming into contact with the flat spring is smaller than the number of first projections coming into contact with a flat spring not including enlarged portions, and therefore it is It is possible to reduce a force required to insert the second connector terminal into and remove the second connector terminal from the first connector terminal, maintaining a stable contact between the second connector terminal and the flat spring. It is preferable that the flat spring comprises a central area enlarging in a curved shape, the enlarged portion being formed in the central area. By being inserted into the first connector terminal, the second connector terminal may contact at the certain area with the enlarged portion which is formed in the central curved area. It is preferable that the flat spring comprises a plurality of enlarged portions coming into contact with the at least two first projections, the enlarged portions being disposed in the width direction of the flat spring.
    [0005] By supporting the second connector terminal at the certain area with a plurality of enlarged portions, it is possible to improve contact stability between the second connector terminal and the flat spring.
    [0006] It is preferred that each of the enlarged portions come into contact with the at least two first projections. By designing each of the enlarged portions to contact the at least two first projections, it is possible to further improve stability in the contact between the second connector terminal and the flat spring. It is preferred that each of the first 5 protrusions have a curved cross section in a direction perpendicular to the first direction. By designing each of the first projections to have a curved cross-section, the flat spring is hardly damaged when the second connector terminal is inserted into the first connector terminal. For example, the first protrusions can be formed by working with the press. In making the second connector terminal from a single sheet, the first projections can be easily formed by working the sheet metal press. It is preferable that a distance between the at least two first protrusions is equal to a distance between the certain zone and one of the side walls, the last distance to be measured when the certain zone is disposed at a center of the spring. dish. It is preferable that a distance between the at least two first protrusions is equal both at a distance between the certain zone and one of the side walls and at a distance between the certain zone and the other of the side walls, the two last distances to be measured when the certain zone is disposed at a center of the flat spring. It is preferred that the second connector terminal comprises three or more first projections, a distance between the first projections located adjacent to each other being equal to each other.
    [0007] It is preferred that each of the first projections disposed at opposite ends in the width direction of the second connector terminal have an angled surface facing outward.
    [0008] It is preferable that the first projections disposed at opposite ends in the width direction of the second connector terminal (210) are arranged so as not to contact the flat spring even if the second connector terminal moves with respect to the flat spring in the width direction thereof. The advantages obtained by the present invention mentioned above will be described below. In the connector terminal according to the present invention, the flat spring always comes into contact with at least two first projections formed on the second connector terminal in the certain area. Therefore, it is possible to reduce a force necessary to insert the second connector terminal into and remove the second connector terminal from the first connector terminal, and maintain a stable contact between the second connector terminal and the flat spring. Thus, it is possible to improve the reliability of the electrical contact between the first and second connector terminals with the aforementioned reduced force.

Figure 15 illustrates a portion of the conventional connector. [First Embodiment] A connector terminal according to a first embodiment of the present invention is explained below with reference to the drawings. In the description, the term "front" refers to a side at which male and female connectors are inserted into each other, and the term "back" refers to the other side. The connector terminal according to the first embodiment comprises a female connector terminal 110 of a female electrical connector C1, and a male connector terminal 210 of a male electrical connector 02, as illustrated in FIG. female electrical connector C1 comprises a female housing 100 formed by an injection molding process, and the female connector terminal 110 in which a male connector terminal 210 of the male electrical connector 02 is inserted. The female housing 100 comprises a housing body 101, and a locking arm 102. The housing body 101 is in the form of a rectangular parallelepiped, and is formed with six terminal housings 101a arranged vertically in two rows each comprising three housings terminal 101a in face-to-face relationship. The terminal housings 101a extend in a forward-to-back direction. The housing body 101 is formed, at a ceiling thereof, with a stop 101c including a hook 101b to be engaged with a female connector terminal 110 inserted into the terminal housing 101a through a body area in order to thereby prevent the female connector terminal 110 from being removed from the housing body 101. As shown in FIG. 2, the female connector terminal 110 includes a sheath portion 111 as a housing of a female terminal to be mounted in the female housing 100 of the female electrical connector C1, a flat spring 112 housed in the sheath portion 111 in a condition such that the flat spring 112 comes into electrical contact with the sheath portion 111, and a link section 113 located at the rear of the sheath portion 111 for securing a cable (not shown) therein in a compressed condition.
    [0011] The sheath portion 111, the flat spring 112, and the connecting section 113 may be formed integrally by folding an electrically conductive sheet. In the female connector terminal 110 in the first embodiment, the flat spring 112 and the sheath portion 111 are manufactured as separate parts. The sheath portion 111 comprises a floor portion 111a, a pair of side walls 111b and 111c facing each other so that the flat spring 112 is disposed between them, and a ceiling portion 111d. The sheath portion 111 is made to be hollow and to have a rectangular cross section by punching a sheet and folding the side walls 11b and 111c and the ceiling portion 111d to thereby define an opening 111e. The floor portion 111a and the ceiling portion 111d connect the side walls 111b and 111c to each other to thereby define a space in which the flat spring 112 may be disposed, and wherein a later mentioned tab portion of the male connector terminal 210 is inserted to contact the flat spring 112. A stabilizer 111f sits on and extends outwardly from the side wall 111b to prevent the female connector terminal 110 from to be inserted into the female housing 100 upside down, and further, to maintain the posture of the female connector terminal 110 stable once the female connector terminal 110 has been inserted into the female housing 100.
    [0012] Each of the sidewalls 111b and 111c is formed with a cutout 111g in which each of the ear portions 112b of the flat spring 112 is inserted. Each of the sidewalls 111b and 111c is formed with a projection 111h to ensure that a later mentioned tab portion of the male connector terminal 210 is within a width of the flat spring 112 when the male connector terminal 210 is inserted into the sheath portion 111. Each of the projections 111h extends inwardly of the sheath portion 111 by forming a recess 111j at an outer surface of each of the sidewalls 111b and 111c. As illustrated in FIGS. 2 and 5, the flat spring 112 is composed of an elastic contact piece 10, and has a central zone 112m centrally located in a direction Fl in which the tongue portion of the terminal male connector 210 is inserted into the sheath portion 111, i.e., a longitudinal direction of the flat spring 111 and the sheath portion 111. The central zone 112m is designed to be curved, that is, ie to be raised to the ceiling portion 111d. The flat spring 112 is disposed along the floor portion 111a in the longitudinal direction of the sheath portion 111. As shown in Fig. 5, the flat spring 112 comprises a spring body 112a which is curved at the in an arc manner, two ear portions 112b extending outwardly from opposite side edges of the centrally located central zone 112m of the spring body 112a, and an enlarged portion 112c located in the central zone 112m in which the ear portions 112b are formed, and acting as a contact portion for contacting the male contact terminal 210. The flat spring 112 is supported on the floor portion 111a of the sheath portion. 111 at a front end 112d and at a rear end 112e of the flat spring 112. The ear portions 112b located in the central zone 112m are mounted in the cutouts 111g formed at the side walls. 111b and 111c rales thereby preventing the leaf spring 111 to move toward the ceiling portion 111d. Thus, even if the front end 112d and the rear end 112e are free ends, the flat spring 112 can act as a curved flat spring. The enlarged portion 112c is formed to have an enlarged curved surface by stamping the spring body 112 at a surface opposite to a surface at which the flat spring 112 comes into contact with the male connector terminal 210. enlarged portion 112c is centrally formed in the width direction F3 of the flat spring 112, the enlarged portion 112c is at the center of a width of the floor portion 111a or the ceiling portion 111d of the sheath portion. When seen from the ceiling portion 111d, the enlarged portion 112c is curved at opposite ends (front and back ends) thereof in the direction F1. The central zone 112m disposed between the front and rear ends of the enlarged portion 112c is formed to be linear in order to connect the curved front and rear ends to each other. The enlarged portion 112c is longer in a direction parallel to the direction Fl (i.e., a longitudinal direction of the flat spring 112) than in a direction perpendicular to the direction Fl (i.e., the direction the width F3 of the flat spring 112). In addition, the front and rear ends of the enlarged portion 112c are curved in shape to tilt upward toward a center from a periphery of the curved shape thereof. The enlarged portion 112c centrally has a curved cross section along the width direction F3 of the flat spring 112. In the manufacture of the female connector terminal 110, a single sheet is punched into a two-dimensional shape or a development of the 110. Then, the cuts 111g are formed in a developed portion of the sheath portion 111. The flat spring 112 is then placed on the floor portion 111a.
    [0013] Next, the sidewalls 111b and 111c are caused to stand on the floor portion 111e so that the ear portions 112b of the flat spring 112 are mounted in the cutouts 111g. The side wall 111c is then folded over the floor portion 111a to thereby define the ceiling portion 111d, and further partially folded toward the ceiling portion 111d except for one area which is in the form of a recess with which the hook 101b is engaged.
    [0014] The female connector terminal 110 is thus complete. As shown in Fig. 1, the male electrical connector C2 comprises a male housing 200 manufactured by an injection molding process, and a male connector terminal 210 to be inserted into the female connector terminal 110. The male housing 200 is in the form of a rectangular parallelepiped, and is formed with a space 201 in which the male connector terminals 210 protrude and the female housing 100 is mounted. The male connector terminals 210 are housed in the space 201 in two vertical rows each comprising three columns, in correspondence with the female connector terminals 110.
    [0015] As shown in FIG. 3, the male connector terminal 210 includes a needle-like tongue portion 211, an insertion portion 212 through which the male connector terminal 210 is inserted into the male housing 200, and an outer connecting portion 213 coming into mechanical and electrical contact with a metal pad of a printed circuit (not shown). The tongue portion 211 is inserted into the female connector terminal 110 of the female electrical connector C1 so as to thereby come into mechanical and electrical contact with the female connector terminal 110. The tongue portion 211 has a first contact surface 211e at at which the male connector terminal 210 comes into contact with the flat spring 112 of the female connector terminal 110, and a second contact surface 211b, opposite the first contact surface 211a, coming into contact with the 111a of the sheath portion 111. Each of the first and second contact surfaces 211a and 211b is formed with a plurality of first projections 214a and second projections 214b, respectively, which each extend in the direction Fi in which the Male connector terminal 210 is inserted into the female connector terminal 110. Each of the first and second projections 214a and 214b extends linearly. to the outer connecting portion 213 from a tapered portion 211c formed at a distal end of the tongue portion 211. Each of the first and second projections 214e and 214b is adapted to have a curved cross section in a direction d F2 thickness perpendicular to the direction Fi. In the first embodiment, each of the first and second projections 214a and 214b has a semicircular cross section. The first and second projections 214a and 214b are equally spaced from adjacent ones in the width direction F3. The tongue portion 211 in the first embodiment is adapted to have six first and second projections 214a and 214b on each of the first and second contact surfaces 211a and 211b. The insertion portion 211 includes an engagement portion 212a that protrudes outwardly in the width direction F3 of the male connector terminal 210, and a shoulder portion 212b at which the connector terminal male 210 is pushed to insert the male connector terminal 210 into the male housing 200. The insertion portion 212 is inserted into and engaged with the male housing 200.
    [0016] The outer connecting portion 213 extends out of a rear end of the male housing 200. The outer connecting portion 213 comprises at a free end a connecting portion 213e through which the outer connecting portion 213 is welded with a metal pad acting as a signal terminal of a printed circuit. The male connector terminal 210 is made by punching a single sheet in which the first and second projections 214a and 214b have been formed by press-working the first and second contact surfaces 211a and 211b of the tab portion 211, in a shape of the male connector terminal 210, and bending the outer connecting portion 213 to thereby define the connection portion 213a. Since the first and second projections 214a and 214b have already been formed by press-working the first and second contact surfaces 211a and 211b of the tongue portion 211, the first and second projections 214a and 214b can be formed more easily than by performing a process of cutting a single sheet in the male connector terminal 210. The first and second projections 214a and 214b may be formed by cutting the first and second contact surfaces 211a and 211b of the tab portion 211, and the tongue portion 211 and the first and second projections 214a and 214b may be formed by a stamping process or an extrusion process, in which case, however, a press work step must necessarily be performed to form the part. 212 and the outer connecting portion 213, with the result that the manufacturing process of the male connector terminal 2 10 is inevitably complicated. Therefore, it is necessary to form the first and second protrusions 214a and 214b by a process of working with the press. As illustrated in FIG. 7, the first projections 214a at opposite ends of the first projections 214a formed on the first contact surface 211a on which the tongue portion 211 engages the flat spring 112 are chamfered. that is, have a continuous sloping surface 214A on a curved surface. When a sheet is cut in one direction on the first contact surface 211a from the second contact surface 211b, burrs are generated on the outer surfaces of the first projections 214a at opposite ends of the first projections 214a formed on the first surface of the first surface. contact 211a. The inclined surfaces 214A are formed by compressing and squeezing the burrs. The connector terminal according to the first embodiment, having the structure as mentioned above, is used in a manner as mentioned below.
    [0017] As illustrated in FIG. 4, the male connector terminal 210 is caused to be in front of the female connector terminal 110, and then, the female housing 100 of the female electrical connector C1 is inserted into the space 201 formed in the male housing 200 of the male electrical connector 02. The sidewalls 111b and 111c of the sheath portion 111 are formed with the projections 111h (see Figure 2). Therefore, if one tries to insert the tab portion 211 into the sheath portion 111 with a longitudinal line of the tongue portion 211 which is inclined with respect to a longitudinal line of the sheath portion 111 when the portion tongue 211 of the male connector terminal 210 is inserted into the sheath portion 111 of the female connector terminal 110, the position of the tongue portion 211 inserted in the sheath portion 111 is corrected so that the portion of tongue 211 is disposed in a width of the flat spring 112.
    [0018] As illustrated in FIG. 5, when the male connector terminal 210 is advancing with respect to the female connector terminal 110, and therefore, the tab portion 211 is inserted into the sheath portion 111, the tab portion 211 of the male connector terminal 210 makes a first contact with the flat spring 112 at the conical portion 211c which is at a distal end thereof. When the male connector terminal 210 advances further, the tab portion 211 may be brought into contact with the enlarged portion 211c acting as a contact surface with respect to the flat spring 112, since the flat spring 112 is of curved shape, and the enlarged portion 112c is formed in the central zone 112m.
    [0019] Once the tongue portion 211 has come into contact with the enlarged portion 112c, the spring body 112a of the flat spring 112 is elastically deformed due to pressure generated by the tongue portion 211 inserted into the sheath portion 111 As shown in Fig. 6, the tongue portion 211 slides on the enlarged portion 112c at the first contact surface 211a, and further slides on the ceiling portion 111d of the sheath portion 111 at the the second contact surface 211b while the tongue portion 211 is inserted deep into the sheath portion 111. Even if a force, which is generated when the flat spring 112 elastically returns to its initial posture, acts on the first contact surface 211a of the tongue portion 211, since the first projections 214a are formed on the first contact surface 211a, the tongue portion 211 may come into contact with the flat spring 112 in a smaller area than an area in which the first contact surface 211a comes into contact with the flat spring 112 in the case where the first contact surface 211a is a flat surface. Thus, the first projections 214a can reduce a force with which the tongue portion 211 is inserted into and removed from the sheath portion 111. In addition, since the first projections 214a are designed to have a curved cross section, the first projections 214a would not damage the flat spring 112 when the tongue portion 211 is inserted into the female connector terminal 110. As shown in FIG. 7, since the flat spring 112 includes the enlarged portion 112c to contact the portion tongue 211, the first projections 214a come into contact with the enlarged portion 112c. The enlarged portion 112c comes into contact not with all the first projections 214a arranged in the width direction F3, but with the first two projections 214a among the first six projections 214a. Thus, when the tongue portion 211 engages the enlarged portion 112c, the tongue portion 211 may contact the enlarged portion 112c through the smaller number of first projections 214a than the number of first projections 214a. through which the tongue portion 211 engages the flat spring 112 in the case where the flat spring 112 is designed not to include the enlarged portion 112c. Thus, it is possible to maintain the tab portion 211 in stable contact with the flat spring 112, and to reduce a force with which the tab portion 211 is inserted into and removed from the sheath portion 111. In addition, the portion 112c is designed longer in the direction F1 than in the direction of the width F3 of the flat spring 112. Thus, the tongue portion 211 can come into stable contact with the flat spring 112 through the two first projections 214a without causing the first contact surface 211a of the tongue portion 211 to tilt relative to a plane at which the tongue portion 211 engages the enlarged portion 112c. The tongue portion 211 further engages at the second contact surface 112b with the ceiling portion 111d of the sheath portion 111. Thus, since the tongue portion 211 comes into contact not only with the flat spring 112d , but also with the ceiling portion 111d, the tongue portion 211 can contact the female connector terminal 110 in an increased contact area.
    [0020] The second projections 214b are also formed on the second contact surface 211b of the tongue portion 211. Therefore, the tongue portion 211 can contact the ceiling portion 111d of the sheath portion 111 in a smaller area. an area in which the tongue portion 211 contacts the ceiling portion 111d in the case where the second contact surface 211b is a flat surface.
    [0021] Thus, since the tongue portion 211 comes into contact not only with the flat spring 112, but also with the ceiling portion 111, it is possible to improve the reliability of the contact of the tongue portion 211 with the flat spring 112 and 111. In addition, since the second projections 214b formed on the second contact surface 211b can reduce friction to be generated between the tongue portion 211 and the ceiling portion 111d, it is possible to reduce a force with wherein the tab portion 211 is inserted into and removed from the sheath portion 111. In a positional relationship between the female connector terminal 110 and the male connector terminal 210 both shown in FIG. 7, the tab portion 211 of the male connector terminal 210 is centrally disposed with respect to the flat spring 112 of the female connector terminal 110 in the width direction F3. Since the tongue portion 211 is centrally disposed with respect to the flat spring 112, the enlarged portion 112c engages the first two projections 214a centrally disposed relative to the tongue portion 211. As illustrated in FIG. 1, the sheath portion 111 of the male connector terminal 110 is housed in the terminal space 101a of the female housing 100 engaged with the hook 101b. As a result, the female connector terminal 110 can move in the terminal space 101a, for example, when a cable attached in the connecting section 113 is pulled.
    [0022] Furthermore, a positional relationship between the female connector terminal 110 of the female housing 100 and the male connector terminal 210 of the male housing 200 may be deflected due to a tolerance thereof. As illustrated in FIG. 7, even if a positional relationship between the tongue portion 211 and the sheath portion 111 has been shifted in the direction of the thickness F2 of the tongue portion 211 extending perpendicular to the first and second contact surfaces 211a and 211b, the tab portion 211 is clamped between the flat spring 112 and the ceiling portion 111d, and therefore the first projections 214a are held in contact with the flat spring 112. It is assumed that the tongue portion 211 is moved to one side in the sheath portion 111 in the width direction F3 of the flat spring 112 extending parallel to the first and second contact surfaces 211a and 211b and perpendicular to the direction Fi. For example, as shown in FIG. 8, it is assumed that the tongue portion 211 is displaced to the left relative to the center of the flat spring 112. In the first embodiment, a distance LO between the first and second projections adjacent 214a and 214b are arranged to be substantially equal to a distance Li defined as a permitted gap distance for the tongue portion 211 between a position in which the tongue portion 211 is centrally located relative to the flat spring 112 and a position in which the tongue portion 211 comes into contact with the left side wall 111b. Alternatively, the distance Li may be defined as a distance between the left side wall 111b and a left side of the tongue portion 211 when the tongue portion 211 is disposed in the position illustrated in Figure 7.
    [0023] Thus, the tongue portion 211 is designed to have a width such that two or more first projections 214a among the first projections 214a, located near the right side wall 111c of the sheath portion 111 when the tongue portion 211 comes into contact with the left side wall 111b of the sheath portion 111, come into contact with the enlarged portions 112c. Here, a width of the tongue portion 211 means a length measured along a plane defined by the first contact surface 211a extending perpendicular to the direction Fi (see Fig. 3) in which the tongue portion 211 is inserted into and removed from the sheath portion 111. Since the first two projections 214a are held in contact with the enlarged portion 112c of the flat spring 112, the tongue portion 211 can be held in stable contact with the flat spring 112. It is assumed that the tab portion 211 is moved to the other side in the sheath portion 111 in the direction of the width F3, in contrast to the case illustrated in FIG. 8. More specifically, as illustrated in FIG. assume that the tongue portion 211 is moved to the right relative to the center of the flat spring 112. A distance LO between adjacent first and second projections 214a and 214b is adapted to be prat only equal to a distance L2 defined as a permissible distance from the tongue portion 211 between a position in which the tongue portion 211 is centrally of the flat spring 112 and a position in which the tongue portion 211 comes into contact with the right side wall 111c. Alternatively, the distance L2 may be defined as a distance between the right side wall 111c and a right side of the tongue portion 211 when the tongue portion 211 is disposed in the position illustrated in Figure 7. Thus, two first projections or more 214a among the first projections 214a, which are near the left side wall 111d of the sheath portion 111 when the tongue portion 211 comes into contact with the right side wall 111c of the sheath portion 111, come into contact with enlarged portions 112c. As mentioned above, even if the tongue portion 211 moves between the side walls 111b and 111c of the sheath portion 111 in the width direction of the flat spring 112, the first two projections 214a are held in position. contacting the flat spring 112, ensuring that the tongue portion 211 can be kept in stable contact with the flat spring 112.
    [0024] Therefore, the connector terminal according to the first embodiment can reduce a force required to mount the female and male connector terminals 110 and 210 into each other and release them from each other, and improves the reliability of the contact between them.
    [0025] By crushing the burrs generated on the outer surfaces of the first projections 214a which are at opposite ends on the first contact surface 211a to thereby define the inclined surfaces 214A, when the. tongue portion 211 moves in the width direction of the flat spring 112, it is possible to prevent the enlarged portion 112c from being caught by the burrs to thereby allow the tongue portion 211 to move without interference. In addition, by crushing the burrs to thereby define the inclined surfaces 214A, it is possible to prevent the enlarged portion 112c from being damaged by burrs. In the first embodiment, the first projections 214a on which burrs are generated are adapted to be disposed without a range in which the tongue portion 211 moves in the sheath portion 111 in the width direction of the flat spring 112 Thus, even if the burrs remain undetected on the first projections 214a, it is possible to reliably prevent the enlarged portion 112c from being damaged by the burrs, because the first projections 214a which are at the ends opposed on the first contact surface 214a do not come into contact with the enlarged portion 112c. [Second Embodiment] The connector terminal according to a second embodiment of the present invention is explained below with reference to Figs. 10 to 14. Parts or elements that correspond to those of the first illustrated embodiment Figures 5 to 9 are provided with the same references, and function in the same manner as the corresponding parts or elements in the first embodiment, unless explicitly explained below.
    [0026] A female connector terminal 110x shown in Fig. 10 includes a flat spring 112x on which a plurality of enlarged portions 112c are formed. The enlarged portions 112c are arranged in the width direction F3 of the flat spring 112x. The connector terminal according to the second embodiment is adapted to include two enlarged portions 112c. When the male connector terminal 210 is inserted into the female connector terminal 110, in a manner similar to the first embodiment, the male connector terminal 210 first contacts the conical portion 211c of the tongue portion 211 with the two enlarged portions 112c of the flat spring 112x. Once the tongue portion 211 has come into contact with the enlarged portion 112c, a spring body 112a of the leaf spring 112x is resiliently deformed due to a pressure generated by the tongue portion 211 inserted into the sheath portion. 111. The tongue portion 211 slides over the enlarged portions 112c at the first contact surface 211a, and further slides over the ceiling portion 111d of the sheath portion 111 at the second contact surface 211b during that the tongue portion 211 is inserted deeply into the sheath portion 111, as illustrated in FIG. 11. Since the flat spring 112c is formed with a plurality of enlarged portions 112c, a contact zone via which the flat spring 112x comes into contact with the tongue portion 211 is larger than that in the first embodiment. However, since each of the two enlarged portions 112c formed on the flat spring 112x with a space therebetween supports the first two projections 214a among the first projections 214a, it is possible to maintain the tongue portion 211 in stable contact with the flat spring. 112x. In the second embodiment, as illustrated in FIGS. 12 and 13, a distance LO between the first and second adjacent projections 214a and 214b is designed to be substantially equal to the distances Li and L2 each defined as a permissible distance d away from the tongue portion 211 between a position in which the tongue portion 211 is centrally of the flat spring 112x and a position in which the tongue portion 211 contacts the left and right side walls 111b and 111c. Alternatively, the distance L1 may be defined as a distance between the left side wall 111b and a left side of the tongue portion 211 when the tongue portion 211 is disposed in the position illustrated in Figure 12, and the distance L2 may be defined as a distance between the right side wall 111c and a right side of the tongue portion 211 when the tongue portion 211 is disposed in the position illustrated in Figure 12. A distance L3 between the two enlarged portions 112d is designed to to be practically equal to LO X 2, that is to say twice the distance LO. Thus, even if the tab portion 211 moves in the sheath portion 111 in the width direction F3 of the flat spring 112x, the first two projections 214a among the first six projections 214a, disposed closer to the right side wall or left 111c or 111b, come into contact with the corresponding enlarged portion 112c with the tongue portion 211 which contacts the left or right side wall 111b or 111c, respectively. Thus, since the first two projections 214a are held in contact with the flat spring 112x between the left and right side walls 111b and 111c of the sheath portion 111, the tongue portion 211 can be held in stable contact with the flat spring 112x. . In addition, since each of the enlarged portions 112c comes into contact with the first two projections 214a, the tab portion 211 can be kept in even more stable contact with the enlarged portions 112c. In the second embodiment, the flat spring 112x is adapted to include the two enlarged portions 112c, and the two enlarged portions 112c engage the first projections 214a, even if the tongue portion 211 moves in the direction of the width F3. Since it is necessary for at least the first two projections 214a among the first projections 214a to come into contact with at least one of the enlarged portions 112c, for example when the tongue portion 211 moves toward the left side wall 111b, the first protrusions 214a may contact one of the enlarged portions 112c disposed closer to the left side wall 111b, in which case the first projections 214a do not come into contact with the other enlarged portion 112c disposed closer to the right side wall 111c, and vice versa. Since all four first projections 214a come into contact with the two enlarged portions 112c, more specifically, the first two projections 214a come into contact with each of the two enlarged portions 112c in the sheath portion 111, it is possible to improve stability of the contact between the tongue portion 211 and the flat spring 112x.
    [0027] In the second embodiment, the flat spring 112x is designed to be formed with the two enlarged portions 112c. Note that the flat spring 112x may be formed with three or more enlarged portions 112c at the spring body 112a because of a magnitude of force required to insert the tongue portion 211 into and remove the portion of tongue 211 of the sheath portion 111, and the reliability of the contact of the tongue portion 211 on the enlarged portions 112c. Each of the enlarged portions 112c is designed to be longer in a longitudinal direction, i.e. a direction parallel to the direction Fi, than in the direction of the width, i.e. a perpendicular direction. to the direction Fi. Alternatively, each of the enlarged portions 112c may be designed to have a length in a longitudinal direction equal to a length in the width direction F3 of the flat spring 112 or 112x viewed in a plane. In the first and second embodiments, the tongue portion 211 of the male connector terminal 210 is inserted into the sheath portion 111, as the female connector body, including the floor portion 111a, a pair of side walls. 111b and 111c, and the ceiling portion 111d. It should be noted that a female connector body can be defined only with a pair of sidewalls 111b and 111c. INDUSTRIAL APPLICATION The connector terminal according to the present invention is suitable for an electrical connector to be used generally in various fields such as the automotive industry, the electrical / electronic equipment industry, and other mechanical industries. , such as a connector for connecting wires to one another in order to transfer electrical signals through them.
