    [0001] A connector terminal includes a hollow sleeve portion to be inserted into a terminal space formed in a housing of an electrical connector, and a resilient contact piece positioned in the sleeve portion to establish mechanical and electrical contact with a male terminal of an opposite electrical terminal when the male terminal is inserted into the sleeve portion.
    [0002] A female connector terminal to be inserted into a terminal space formed in a connector housing is known to make mechanical and electrical contact with a male terminal of a counter-connector when the male terminal is inserted into the terminal space. thick headed.
    [0003] Fig. 15 is a perspective view of an example of such a female connector terminal, as suggested in Japanese Patent Application Publication No. 200152791. A female terminal 1000 illustrated in Fig. 15 comprises a sleeve portion 1001 and an elastic contact plate 1005 housed in the sleeve portion 1001. The sleeve portion 1001 is formed at a front edge 1003 aligning with an opening edge 1002 thereof with a stepped portion 1004. resilient contact plate 1005 is formed at a leading edge with an engagement portion 1006 to be engaged with the stepped portion 1004. In the female terminal 1000 illustrated in FIG. 15, when a male terminal (not shown) is inserted into the sleeve portion 1001 through the opening thereof, the elastic contact plate 1005 does not move in a direction in which the male terminal is inserted into the sleeve portion 1001, and therefore In fact, the lugs 1007 formed at the elastic contact plate 1005 do not come into marked abutment with inner peripheral edges of windows 1009 formed at side walls 1008 of the sheath portion 1001. Thus, the elastic reaction of the Elastic contact plate 1005 does not interfere with the male terminal in the female terminal 1000, and therefore it is not necessary to insert the male terminal into the sleeve portion 1001 with a large force. Fig. 16 is a perspective view of another example of the female connector terminal mentioned above, suggested in Japanese Utility Model Publication H4 (1992) -8623. A female terminal 1100 shown in FIG. 16 comprises a sleeve portion 1101 for receiving a male terminal (not shown), and an elongated flat spring 1102 housed in the sleeve portion 1101. The flat spring 1102 is formed at its opposite side edges with ears 1103 protruding outward. The flat spring 1102 is fixed in the sleeve portion 1101 by causing the lugs 1103 to be engaged with grooves 1104 formed at side walls of the sleeve portion 1101. The sleeve portion 1101 is formed at side walls with stepped portions 1105 in alignment with lower edges of the grooves 1104. Therefore, the stepped portions 1105 support the lugs 1103 of the flat spring 1102, and the lugs 1103 are further supported on the lower edges of the grooves 1104 to thereby find themselves in a desired position. The female terminal 1000 illustrated in Fig. 15 has a problem in that, since the engagement portion 1006 formed at a front edge of the resilient contact plate 1005 is engaged only on the stepped portion 1004, the Elastic contact 1005 can float at its front edge with respect to a desired position. If the male terminal is inserted into the sleeve portion 1101 while the elastic contact plate 1005 floats at the leading edge, the male terminal comes into contact with and pushes the leading edge, with the result that there is a risk that the elastic contact plate 1005 can be bent or damaged by the male terminal.
    [0004] In the female terminal 1100 shown in Fig. 16, since the stepped portions 1105 are formed in alignment with the lower edges of the grooves 1104, the flat spring 1102 can be moved at a leading edge to a level of the grooves 1104. Thus, if the flat spring 1102 is moved at a leading edge to a level of the grooves 1104, the male terminal inserted in the sleeve portion 1101 engages and pushes the leading edge of the flat spring 1102, as a result, there is a risk that the flat spring 1102 may be bent or damaged by the male terminal. As mentioned above, the conventional female terminals 1000 and 1100 have a problem in that, when the male terminal is inserted into the sleeve portion 1001 or 1101, it is possible that the male terminal may bend or damage the plate contact 1005 or the flat spring 1102 resulting in a fault in the electrical contact between the female and male terminals. Because of the above mentioned problems in conventional female terminals, it is an object of the present invention to provide a connector terminal capable of securely enabling a male terminal to make contact with an elastic plate of contact a female terminal to thereby provide an extremely reliable contact between male and female terminals. According to one aspect of the present invention there is provided a connector terminal comprising a hollow sheath portion to be inserted into a terminal space formed in a housing of an electrical connector, and an elastic contact piece positioned in the sheath portion. , the contact piece establishing mechanical and electrical contact with a male terminal of an opposite electrical connector when the male terminal is inserted into the sleeve portion, the male terminal being inserted into the sleeve portion through an insertion passage formed in the housing, the sheath portion being formed with a protrusion on at least one of the inner walls thereof, the projection cooperating with a distal end of the contact piece so that said distal end is out of the a cross-section of the insertion passage in a direction perpendicular to a direction in which the male terminal is inserted in the scabbard part. According to the connector terminal mentioned above, the projection constrains the distal end of the contact piece to be located outside a cross section of the insertion passage. That is, even if the elastic contact piece tends to float at its distal end which thus tends to come into a cross section of the insertion passage, the projection abuts with the distal end of the resilient contact piece to prevent the elastic contact piece from moving. Thus, it is possible to prevent the distal end of the elastic contact piece from interfering with the male terminal.
    [0005] For example, the projection may be formed by forming a recess on an outer surface of a side wall of the sleeve portion. The protrusion may be formed on side walls of the sleeve portion simply by working a sheet metal to the press without the need to re-form a portion on the side walls as a protrusion. It is preferred that the protrusion be formed on each of the two inner walls of the sleeve portion. By forming the projections on each of the two inner walls of the sleeve portion, the distal end of the resilient contact piece can establish uniform contact at the side edges with the projections, ensuring that it prevents the workpiece. of elastic contact to move or float. That is, a pair of projections prevents the elastic contact piece from moving only at one of the side edges. It is preferred that the contact piece is formed with a raised portion at which the contact piece contacts the male terminal, a distance between the projection and a top of the raised portion being smaller than a width. of the male terminal. Even if a male terminal is inserted into the sleeve portion such that a longitudinal axis of the male terminal is off-axis from the sleeve portion and is deflected to one of the side walls of the sleeve portion, the projection allows the male terminal and the raised portion to establish a stable contact with each other. It is preferable that a distance between the protrusions is smaller than a width of an opening through which a template is inserted into the housing in order to release the sheath portion that has been engaged to a engagement portion. in the terminal space. It is preferable that a distance between the projection and the bottom wall facing the protrusion is smaller than a width of an opening through which a template is inserted into the housing to release the sheath portion that has been removed. engaged up to a commitment part in the terminal space. Even if a user tries to insert a template not in the opening but in the sheath portion, an interior space of the sheath portion is narrowed by the projection, and therefore, it is possible to prevent the user to insert a template incorrectly into the sleeve portion.
    [0006] It is preferable that the sleeve portion has a larger opening in four directions than the insertion passage when the connector terminal is inserted into the housing. The advantages obtained by the present invention mentioned above will be described below. According to the aforementioned connector terminal, the protrusion comes into contact with a distal end of the resilient contact piece to thereby prevent the elastic contact piece from moving in an area corresponding to the insertion passage. As a result, the elastic contact piece does not interfere at a distal end thereof with a male terminal that has been inserted into the sleeve portion. Thus, the male terminal can securely establish mechanical and electrical contact with the resilient contact piece to thereby provide an extremely reliable electrical connection between the male terminal and the connector terminal.

    [0012] Fig. 16 is a perspective view of the second conventional connector terminal. A connector terminal according to the preferred embodiment of the present invention and an electrical connector using the connector terminal are explained below with reference to the drawings. In the description, the term "forward" or "forward" refers to a direction in which the connector terminal is inserted into a housing (i.e., an X direction shown in FIG. ), and the term "backward" or "backward" refers to the opposite direction. An electrical connector 10 illustrated in FIGS. 1 to 4 is a female connector in which a male connector C (see FIG. 11) comprising male terminals P each in the form of a needle is inserted. The electrical connector 10 includes a housing 20 formed by an injection molding process, and a plurality of female connector terminals 30 according to the preferred embodiment of the present invention. Each of the male terminals P of the male connector C is inserted into the corresponding connector terminal 30 in order to thereby make electrical contact with the connector terminal 30.
    [0013] The housing 20 comprises a housing body 21, and a locking arm 22. The housing body 21 is in the form of a rectangular parallelepiped, and is formed with a total of six terminal spaces 21a (see Fig. 4) arranged horizontally in three rows and vertically in two rows. The terminal spaces 21a extend in the X direction (see FIG. 1). The housing body 21 is formed at the front 21b with a plurality of insertion apertures 21c through which the male terminal P is inserted into the housing body 21. As shown in FIGS. 3 and 4, each of the insertion apertures 21c comprises a guide portion 21d having a rectangular section and having a smaller inside width at a location closer to the terminal space 21a for the purpose of causing the male terminal P to move towards a central axis of the insertion opening 21c, and a passage 21e having an internal width equal to the smallest inner width of the guide portion 21d, and connecting to each other via the guide portion 21d and the terminal space 21a. As illustrated in FIGS. 1, 2 and 4, housing body 21 is formed in front 21b with template insertion openings 21f through which a template is inserted into housing body 21 in each case. the purpose of releasing the connector terminal 30 of the housing body 21. As illustrated in FIG. 4, the housing body 21 is formed at an inner ceiling 21g with a stop 21j comprising a hook portion 21b . The hook portion 21h is engaged with the connector terminal 30 which has been inserted into the terminal space 21a through the rear of the housing body 21, thereby to prevent the connector terminal 30 from being released from the housing. housing body 21. The locking arm 22 includes a front end connected to the housing body 21, an arm body 22b supported by the front end 22a, a release member 22c used to unlock the connector terminal 30 of the housing body. housing 21, and a rear end connected to the housing body 21 and located under the release member 22c.
    [0014] The front end 22a is elastically deformed when the release member 22c is pushed down. The arm body 22b comprises a claw 22e to be engaged with a housing H of the male connector C to thereby lock the housing H on the housing body 21.
    [0015] The release member 22c is formed on the arm body 22b in a location between the front end 22a and the rear end 22d, and extends obliquely and upwardly toward the rear end 22d. When the release member 22c is pushed down, the arm body 22b is deformed downward with both the front end 22a and the rear end 22d acting as fulcrums, and in abutment with the rear end 22d. Then, the arm body 22b is deformed with a surface at which the front end 22a and the release member 22c abut with the rear end 22d which acts as a fulcrum. Thus, the housing 20 is unlocked from the housing H of the male connector C. The connector terminal 30 is explained below with reference to the drawings. As illustrated in FIGS. 5 to 8, the connector terminal 30 comprises an electrically conductive hollow sheath portion 31 to be inserted into the housing 20, an elastic contact piece 32 positioned in the sheath portion 31 so that the contact piece 32 is electrically connected to the sleeve portion 31, and a beam portion 33 extending rearwardly from the sleeve portion 31.
    [0016] A cable (not shown) is compressed and fixed in the beam portion 33. The sleeve portion 31, the resilient contact piece 32 and the beam portion 33 are formed integrally with each other. folding an electrically conductive sheet. Alternatively, the resilient contact piece 32 may be formed as a separate portion of the sleeve portion 31. The sleeve portion 31 is formed by punching a sheet into a desired shape, and folding a bottom 31a, side walls. 31b and 31c and a ceiling 31d in a quadratic prism. The sleeve portion 31 is formed at the side wall 31b with a stabilizer standing vertically 31e to prevent the connector terminal 30 from being inserted upside down in the housing 20, and further to stabilize a position of the connector terminal 30 with respect to the housing 20 once the connector terminal 30 has been inserted into the housing 20. The sleeve portion 31 is formed at the inner walls 31bA and 31cA of the side walls 31b and 31c with projections 31f. As mentioned below in detail, the projections 31f force a distal end of the contact piece 32 to be outside a cross section of the insertion opening 21c. For example, the projections 31f may be formed by forming recesses 31g on an outer surface of the side walls 31b and 31c of the sleeve portion 31.
    [0017] The sleeve portion 31 is formed at the side walls 31b and 31c with cutouts 31h in which tabs 32b of the resilient contact piece 32 are disposed.
    [0018] The elastic contact piece 32 is constituted by a curved flat spring on the bottom 31a in a longitudinal direction of the sleeve portion 31. The resilient contact piece 32 comprises a flat spring 32a bending in a curved shape, tabs 32b s extending perpendicularly from side edges of the flat spring 32a at a longitudinal center of the flat spring 32a, and a raised portion 32c formed on the flat spring 32a between the legs 32b. The raised portion 32c comes into contact with the male terminal P.
    [0019] As illustrated in FIG. 8, the elastic contact piece 32 is supported on the bottom 31a of the sleeve portion 31 at the front and rear ends 32d and 32e thereof, and the tabs 32b located at the a longitudinal center of the resilient contact piece 32 is inserted into the cutouts 31h formed at the side walls 31b and 31c of the sleeve portion 31, preventing the resilient contact piece 32 from moving towards the ceiling 31d. Thus, even if the front and rear ends 32d and 32e act as free ends, the resilient contact piece 32 can act as a curved flat spring. The raised portion 32c is hemispherical (see Figure 6), and may be formed on an upper surface of the flat spring 32a forming a recess on a lower surface of the flat spring 32a. The connector terminal 30 is formed as follows. First, a sheet in which the projections 31f have already been formed is punched into a desired contour including the sheath portion 31 in a developed condition. The cuts 31f are formed when the sheet is punched into the desired contour. Then, the elastic contact piece 32 is positioned on the bottom 31a of the sleeve portion 31.
    [0020] The side walls 31b and 31c are then caused to straighten with respect to the bottom 31a so that the tabs 32b of the resilient contact piece 32 are inserted into the cutouts 31h. Then, the side wall 31c is folded to thereby form the ceiling 31d above the bottom 31a, and the remainder with the exception of a portion which will be a recess 31j with which the hook portion 21h (see Figure 4 ) is engaged is folded towards the ceiling 31d. The connector terminal 30 is thus terminated.
    [0021] The connector terminal 30 having the above-mentioned structure, according to the preferred embodiment, is used as follows. Fig. 9 is a sectional view of a conventional electrical connector 100 and the male connector C connected to each other. When a user mounts the male connector C into the conventional electrical connector 100, as shown in FIG. 9, the elastic contact piece 32 can float or collapse under its own weight at a distal end 32d in the sleeve portion 310 of the connector terminal 300. For example, since the connector terminal 300 is in a lower terminal space in the housing 20, the resilient contact piece 32 collapses at the distal end 32d in Figure 9. Since the distal end 32d of the elastic contact piece 32 is not limited in its movement, the distal end 32d collapses over a portion of a cross section of the insertion opening 21c through which the male terminal P is inserted into the housing 20, and thus, the distal end 32d is positioned to be visible through the insertion opening 21c. Therefore, when the male terminal P is inserted into the housing 20 through the insertion opening 21c, the male terminal P abuts with the distal end 32d, and then pushes the distal end 32d towards the 20. As a result, there is a risk that the elastic contact piece 32 may be bent or damaged at its distal end 32d. Fig. 10 is a sectional view of the electrical connector 10 and the male connector C connected to each other. Since the sleeve portion 31 of the connector terminal 30 is formed at the inner walls 31bA and 31cA of the side walls 31b and 31c with the projections 31f, even if the elastic contact piece 32 floats or collapses at the level of the 32d on a portion of a cross section of the insertion opening 21c, the projections 31f abut with side edges 32dA (see Fig. 7) of the distal end 32d to thereby prevent the distal end 32d to enter the portion mentioned above. Thus, the distal end 32d of the elastic contact piece 32 does not interfere with the male terminal P, and therefore does not prevent the male terminal P from being inserted into the sleeve portion 31. Therefore, as this is illustrated in Figure 11, the male terminal P can be inserted smoothly and fully into the sleeve portion 31 without interference with the elastic contact piece 32. Thus, the connector terminal 30 can provide an extremely reliable electrical connection with the male terminal P.
    [0022] In the present embodiment, as previously mentioned, each of the insertion apertures 21c comprises the guide portion 21d having a smaller inside width at a location closer to the terminal space 21a, and the passage 21e. connecting through the guide portion 21d and the terminal space 21a to each other. Thus, the projections 31f retain the distal end 32d of the elastic contact piece 32 so that the displacement of the distal end 32d is outside a cross section of the passage 21e having an inner width equal to the smallest width inner portion of the guide portion 21d. Therefore, the projections 31f prevent the distal end 32d of the resilient contact piece 32 from moving toward a longitudinal axis of the sleeve portion 31, with the result that the distal end 32d is substantially flush with a leading edge. opening of the 21st passage.
    [0023] The guide portion 21d is designed to have a smaller inside width at a location closer to the terminal space 21a, and the passage 21 is designed to have an interior width equal to the smallest inside width of the guide portion. 21d and to connect through the guide portion 21d and the terminal space 21a to each other. Thus, the sleeve portion 31 may be designed to have a cross-section depending not on a larger cross-section of the insertion opening 21c but on a smaller cross-section of the opening of the opening. 21c insertion, that is to say a cross section of the passage 21e. Therefore, the sleeve portion 31 may be designed to have a small width and a small height, contributing to the reduction of the size of the connector terminal 30. In the present embodiment, the projections 31f are formed forming the recesses 31g on an outer surface of the side walls 31b and 31c of the sleeve portion 31. Thus, it is not necessary to add a separate part as projections 31f on the side walls 31b and 31c. The projections 31f may be formed on the side walls 31b and 31c simply by working a sheet metal to the press. As shown in Fig. 6, since the projections 31f are formed on the inner surfaces 31bA and 31cA of the side walls 31b and 31c, the projections 31f abut uniformly with side edges of the distal end 32d of the housing. elastic contact 32. Thus, the projections 31f prevent the elastic contact piece 32 from floating and sagging, making sure that it is possible to prevent the elastic contact piece 32 from floating or collapsing at level of one of the side edges 32dA thereof. After having been inserted into the connector terminal 30, the male terminal P comes into contact with the raised part 32c (see FIG. 6) of the elastic contact piece 32.
    [0024] For example, as shown in Fig. 12, in the case where a sleeve portion 310 of a connector terminal 300 is designed not to include the projections 31f, the male terminal P can be inserted into the sleeve portion. 310 out of a longitudinal axis of the sleeve portion 310, and deflected to one of the side walls 310. In such a condition, the male terminal P is positioned at a longitudinal axis outside a vertex 32f of the part raised 32c of the elastic contact piece 32, resulting in poor stability in the male terminal P and a reduction of a surface through which the male terminal P and the elastic contact piece 32 come into contact with the one with the other. This can cause a defect in the electrical connection between the male terminal P and the elastic contact piece 32. However, as illustrated in FIG. 13, since the distance X1 between the projection 31f and the top 32f of the raised part 32c is smaller than the width X2 of the male terminal P in the connector terminal 30, even if the male terminal P is positioned at a longitudinal axis outside the vertex 32f of the raised portion 32c, and is inserted into the part of sheath 310 in a deflection condition to one of the side walls 310, it is possible to ensure that the male terminal P makes a stable contact with the raised portion 32c of the elastic contact piece 32. When the connector terminal 30 is released from the housing 20, using a template (not shown). The sleeve portion 31 of the connector terminal 30 which has been inserted into the terminal space 21a is engaged with the housing 20 by means of the stop 21j. The template releases the engagement of the sleeve portion 31 with the stop 21j to thereby allow the connector terminal 30 to be removed from the housing 20. When the connector terminal 30 is removed from the housing 20 by means of the template, the template is inserted into the template insertion openings 21f (see Figures 1 and 3) formed at the front 21b of the housing 20. If a user improperly inserts the template into the insertion opening 21c formed at the front 21b of the housing 20, even if the user intends to insert the template into the template insertion opening 21f, the elastic contact piece 32 may be damaged by the template. As illustrated in FIGS. 6 and 14, since the sleeve portion 31 is formed at the inner surfaces 31bA and 31cA of the side walls 31b and 31c with the projections 31f, a distance L2 between the facing projections 31f is more small a distance L1 between the side walls 31b and 31c (here, the distance L1 is equal to a width of the guide portion 21d at the rear end or a width of the passage 21e). The template has a width equal to a width L3 of the template insertion aperture 21f. Therefore, even if a user attempts to improperly insert the template into the insertion aperture 21c, the template abuts with the projections 31f which thereby stop its insertion. In addition, if the template has a width smaller than the width L1 of an opening of the sleeve portion 31, but larger than the distance L2 between the projections 31f, the template abuts with the projections 31f which thus stop his insertion. It is thus possible to prevent the elastic contact piece 32 from being damaged by the incorrect insertion of the template into the insertion opening 21c. The sleeve portion 31 in the present embodiment is adapted to include a pair of projections 31f formed on the inner surfaces 31bA and 31cA of the side walls 31b and 31c. It should be noted that the sleeve portion 31 may be designed to include a projection 31f on one of the inner surfaces 31bA and 31cA of the side walls 31b and 31c. As shown in Figures 5 and 10, each of the projections 31f in the present embodiment is square when viewed from above. It should be noted that a shape of the projection 31f should not be limited to a square.
