    [0001] The present invention relates to a connector terminal used for electrical connection between devices mounted in an automobile for example. The present invention further relates to a connector comprising the connector terminal, and a resilient piece as part of the connector terminal. As a connector in which a printed circuit board having a terminal at a marginal area of a surface is mounted, there is known a connector suggested in Japanese Patent No. 3669268. Figure 18 is a sectional view of the suggested connector. in Japanese Patent No. 3669268. As shown in Fig. 18, the connector 100 consists of a first housing 101 and a second housing 102 insertable into the first housing 101. The first housing 101 includes a printed circuit board 103 having a terminal 104 at a marginal area of a surface thereof. The second housing 102 includes a metal terminal 105 which makes contact with the terminal 104 when the second housing 102 is mounted in the first housing 101. The metal terminal 105 is formed by bending an electrically conductive sheet. The metal terminal 105 includes at a rear end a wire connector 111 to which a wire W may be connected. The metal terminal 105 further comprises a hollow connector 116 at the front of the wire connector 111, and an elastic contact piece 109 located in the hollow connector 116 and substantially folded in a loop. The first housing 101 comprises at a lower inner wall 106 a pair of pushers 107 extending towards an opening of the first housing 101. Each of the pushers 107 comprises at a distal free end a guide surface 108 through which the elastic contact piece 109 of the metal terminal 105 is pushed. In the connector 100, when the second housing 102 is inserted into the first housing 101, as shown in FIG. 19, the printed circuit board 103 enters the second housing 102 through an opening 112, and then the push-buttons 107 enter spaces 114 through apertures 113. As shown in FIG. 20, as printed circuit board 103 advances into second housing 102, guide surfaces 108 push a portion 115 of the elastic contact piece 109. Thus, the elastic contact piece 109 is elastically deformed toward the printed circuit board 103. When the printed circuit board 103 is moved to a predetermined position, the first and second housings 101 and 102 are completely mounted on one another. the other, and in this condition, the pushers 107 push the first flexion points 117 of the resilient contact piece 109 towards the printed circuit board 103 to thereby bring the resilient contact piece 109 to come into contact, at a contact portion 118 thereof, with the terminal 104 of the circuit board 103.
    [0002] However, the above-mentioned connector 100 is accompanied by a problem that, when the printed circuit board 103 enters deeply into the opening 112, the guide surfaces 108 push not only the portions 115 to thereby cause the elastic contact piece 109 to be elastically deformed towards the printed circuit board 103, but also the elastic contact piece 109 in its entirety in a bottom of the opening 112, with the result that the elastic contact piece 109 is deformed . If the elastic contact piece 109 is deformed a first time, the elastic contact piece 109 can not return to its initial position, causing as a problem that the connector 109 can not function completely.
    [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 avoiding being distorted when a printed circuit board is mounted in a connector housing. . It is another object of the present invention to provide a connector comprising the connector terminal.

    [0004] When a printed circuit board is inserted into the second space of the connector housing comprising the connector terminal according to the present invention, the printed circuit board makes contact with the contact portion of the resilient piece with the result that the elastic piece is pushed into the first space from the second space. Although the resilient piece is caused to withdraw to an opening through which the connector terminal is passed into the first space, the stop comes into contact with the elastic piece to thereby prevent the elastic piece from being removed. It is preferable that the connector housing includes a protrusion protruding in the second direction and which can be inserted into the terminal body, and is formed with an opening between the first and second spaces, the contact portion being able to pass through the opening, the resilient piece having an end that is slidable on the projection when the connector terminal is inserted into the first space, the contact portion being caused to protrude into the second space from the first space through the opening when the end slides on the projection. It is preferable that the stop is located so as to abut with or be in the vicinity of the other end of the elastic piece. It is preferred that the terminal body be formed at a side wall with an opening, the stop extending inwardly of the terminal body from an inner edge of the opening. It is preferable that the abutment is formed by cutting into a side wall of the terminal body, and bending the side wall inwardly of the terminal body.
    [0005] It is preferable that the resilient piece comprises a first curved portion, a second portion extending from one end of the first portion and having a free distal end, and a third portion extending from the other end of the first portion. and having a free distal end, the contact portion being formed at the third portion so as to protrude outwardly into a V-shape, the third portion being formed such that a portion thereof comprising the free distal end is inclined towards the second part so as to form a space between its free distal end and the free distal end of the second part. It is preferable that the portion of the third portion is curved into a V shape. It is preferred that the second portion include a curved portion between a distal end and the first portion, the curved portion protruding toward the third portion.
    [0006] In another aspect of the invention, there is provided an elastic member to be housed in an at least partially hollow terminal body, the resilient member being inserted with the terminal body in a connector housing, the connector housing comprising a first a space having an opening through which the terminal body is inserted therein, and a second space in which a printed circuit board is inserted, the second space being located adjacent to the first space, the resilient piece and the terminal body being both inserted and housed in the first space through the opening, the resilient piece including a contact portion resiliently projecting in the second space from the first space.
    [0007] In yet another aspect, there is provided a connector comprising a connector housing and a connector terminal, the connector housing comprising a first space having an opening through which the connector terminal is inserted therein, and a second space in which a printed circuit board is mounted, the second space being located adjacent to the first space, the connector terminal being inserted and housed in the first space through the opening, the connector terminal comprising an at least partially hollow terminal body and an elastic piece to be accommodated in the terminal body, the elastic piece comprising a contact portion resiliently projecting in the second space from the first space, the terminal body including a stop limiting movement of the elastic piece in a second direction opposite to a first direction in which the connector terminal is inserted in the first space. The advantages obtained by the present invention mentioned above are described below.

FIG. 3, FIG. 10 is a perspective view of a sheet from which the terminal body illustrated in FIG. 6 is manufactured, and FIG. 11 is an enlarged view of a portion 210 shown in FIG. 10. As illustrated in FIGS. 1 and 2, a connector 1 according to the embodiment of the present invention is what is called a printed circuit board connector in which a printed circuit board 210 on which a terminal 240 is formed at a marginal area is inserted. The printed circuit board 210 is fixed in a housing 230. The connector 1 consists of a connector housing 2, and a connector terminal 3 which comes into electrical contact with the terminal 240 of the printed circuit board 210 A cable 220 is connected to the connector terminal 3. As shown in FIGS. 3 to 5, the connector housing 2 comprises a cover 20 open at one end to allow the housing 230 to be inserted at an end. through. The cover 20 is formed with a first space 22 in which the connector terminal 3 is inserted, and a second space 21 in which the housing 230 which fixes the printed circuit board 210 is inserted. The first and second spaces 22 and 21 are located adjacent to each other. The connector housing 2 comprises, on a side opposite the cover 20 with respect to the second space 21, an opening 23 through which the connector terminal 3 is inserted in the first space 22. The connector terminal 3 comprises a terminal body 4 as a first terminal portion, illustrated in FIG. 6, and an elastic member 5 as a second terminal portion illustrated in FIG. 9. The terminal body 4 is adapted to have an opening 40 at a forward end in a direction 250 (see Fig. 3) in which the connector terminal 3 is inserted into the connector housing 2. As shown in Fig. 9, the resilient piece 5 is formed by being bent at one end so that a gap 50 is formed between opposite ends 5a and 5b. The elastic part 5 is housed in the terminal body 4 so that the space 50 faces the opening 40 of the terminal body 4. The connector terminal 3 is inserted into the first space 22 through the opening 23, and held in the first space 22. The connector housing 2 is formed with a plurality of first spaces 22 arranged vertically in two zigzag rows, and further with a plurality of second spaces 21 disposed above and below below the two vertical columns of the first spaces 22. The connector terminal 3 is inserted into each of the first spaces 22. As shown in FIG. 5, the connector housing 2 comprises a projection 24 in the first space 22. The projection 24 is in front of the connector terminal 3, and protrudes towards the space 50 of the elastic part 5 of the terminal body 4 inserted into the first space 22. The projection 24 has an inclined upper surface 24a. The upper surface 24a tilts in such a way that one side of the projection 24 which is further away from the second space 21 than the other side 24b (see Fig. 16A) is located closer to the opening 23 The connector housing 2 is further formed with an opening 25 between the first and second spaces 22 and 21 so as to allow the resilient piece 5 to partially protrude into the second space 21. The terminal body 4 is formed by folding an electrically conductive sheet 4a shown in Figure 10. The sheet 4a is cut in advance in a predetermined shape. Although FIG. 10 only illustrates a part of the sheet 4a for the manufacture of a single terminal body 4, parts of the sheet 4a for the manufacture of a plurality of terminal bodies 4 are connected to each other. other by supports 6a and 6b which are at opposite ends of each of the terminal bodies 4.
    [0017] As illustrated in FIG. 6, the terminal body 4 comprises a sheath portion 41 in which the elastic piece 5 is housed, and a beam portion 42 in which the cable 220 is fixed in a compressed condition. The beam portion 42 includes a first section 42a for securing an outer electrical insulation of the cable 220, and a second section 42b for holding the cable 220 to allow the cable 220 to make electrical contact with the cable portion 220. sheath 41.
    [0018] The terminal body 4 further comprises an attachment section 43 for fixing the elastic piece 5 in the sheath portion 41 to allow the elastic piece 5 to make an electrical connection with the sheath portion 41. As this is illustrated in Figures 6 and 7, the attachment section 43 comprises a projecting portion 44a facing the elastic piece 5, and a fixing portion 44b formed by cutting a side wall of the terminal body 4. The elastic piece 5 is fixed between the projecting portion 44a and the attachment portion 44b by folding the attachment portion 44b on the elastic piece 5. The sheath portion 41 further comprises a stop 45 at the rear to prevent withdrawal of the elastic piece 5 The abutment 45 is formed by making a cut in a side wall of the terminal body 4, and by bending the side wall perpendicularly to the inside of the terminal body 4. The stop 45 is located so as to aligning a stop with or near a first curved or arcuate portion 51 (see Figure 9) of the elastic piece 5. The terminal body 4 is formed at a wall facing the securing section 43, with an opening 46 (see Fig. 7) so that the elastic piece 5 can protrude into the second space 22 through the opening 25 and further through the opening 46. The protruding portion 44a is formed by punching the sheet 4a. The projecting portion 44a may be formed at the elastic part 5 instead of the terminal body 4.
    [0019] Briefly, the protrusion 44a is designed to face the resilient piece 5 when the terminal body 4 includes the protrusion 44a, while the protrusion 44a is adapted to face the terminal body 4 when the elastic member 5 includes the projecting portion 44a. The elastic piece 5 can be fixed to the terminal body 4 by welding the elastic piece 5 to the terminal body 4 instead of deforming the fixing portion 44b. As illustrated in FIG. 9, the elastic part 5 comprises the first curved or arcuate part 51, a second part 53 extending from one end of the first part 51 and having a free distal end 5a, and a third part 56 extending from the other end of the first portion 51 and having a free distal end 5b. The distal ends 5a and 5b are spaced from each other to thereby form the above-mentioned space 50. The second portion 53 includes a curved portion 54 between the distal end 5a and the first portion 51. The curved portion 54 protrudes in arcuate form toward the third portion 56. The second portion 53 is formed flat between the distal end 5a and the curved portion 54.
    [0020] The third portion 56 includes a contact portion 55 resiliently protruding into the second gap 21 from the first gap 22. The contact portion 55 protrudes outwardly V-shaped. The third portion 56 includes a portion 52 including the free distal end 5b thereof. The portion 52 is bent V-shaped to thereby protrude to the second portion 53. The portion 52 acts as a sliding portion which is slidable on the upper surface 24a of the projection 24.
    [0021] As illustrated in FIG. 9, the elastic part 5 is formed by folding a sheet so that the two free distal ends 5a and 5b form the space 50 between them, and that the first portion 51 protrudes in a curved shape towards the rear of the connector terminal 3. The portion or sliding portion 52 comprising the distal end 5b facing the distal end 5a at which the elastic piece 5 is fixed to the terminal body 4 by the The intermediate of the fixing section 43 has an inverted V shape such that the sliding portion 52 can slide smoothly on the upper surface 24a of the projection 24 when the connector terminal 3 is inserted into the first space 22.
    [0022] The second portion 53 is formed flat so as to come into close contact with an inner wall of the terminal body 4. Below is explained a process for manufacturing the connector terminal 3 with reference to FIGS. FIG. 12 is a perspective view of the elastic part 5 before assembly in the terminal body 4, FIG. 13 is a perspective view of the elastic part 5 placed on the sheet 4a, FIG. 14 illustrates the connector terminal 3 which is assembled, and FIG. 15 is a perspective view of the connector terminal 3 which is assembled, following FIG. 14. In a manufacturing process of the elastic part 5, an electrically conductive sheet is punched in a predetermined shape, and then folded into a shape as shown in Fig. 12. In a similar manner to the aforementioned terminal body 4, although Fig. 12 illustrates a portion of a sheet for the manufacture Only with the elastic part 5, parts of a sheet for the manufacture of a plurality of elastic parts 5 are actually connected to each other by means of supports 7. As illustrated in FIG. Fig. 13, after the resilient piece 5 shown in Fig. 12 is placed on the sheet 4a shown in Fig. 10, the sheet 4a is bent at predetermined portions to thereby provide the terminal body 4, as is illustrated in Figure 14, and in this condition, the terminal body 4 and the elastic part 5 are always connected to the supports 6a, 6b and 7. Then, the supports 6a, 6b and 7 are cut.
    [0023] Thus, as illustrated in FIG. 15, terminating the connector terminal 3 comprising the terminal body 4, and the elastic part 5 fixed on the terminal body 4. In the connector terminal 3, since the elastic part 5 is fixed on the terminal body 4 in a location close to the opening 40 of the terminal body 4, the elastic part 6 can be easily assembled in the terminal body 4, and furthermore, it is possible to cut the supports 7 of the elastic piece 5 once the elastic piece 5 has been assembled in the terminal body 4. In addition, the elastic piece 5 and the terminal body 4 come into contact with each other not by a contact plane between a surface of the elastic piece 5 and a surface of the terminal body 4, but by a point contact 15 between a surface of the elastic piece and a top of the projecting portion 44a, which ensures an improvement of the reliability in the contact between the elastic piece 5 and the c Terminal 4. The following is explained a process of assembling connector terminal 3 in connector housing 2 with reference to FIGS. 16A-16C. Fig. 16A is a sectional view showing a positional relationship between connector terminal 3 and connector housing 2 before connector terminal 3 is fully inserted into connector housing 2, Fig. 16B is a view of section showing a positional relationship between the connector terminal 3 and the connector housing 2 while the connector terminal 3 is being inserted into the connector housing 2, and Fig. 16C is a sectional view showing a positional relationship between the connector terminal 3 and the connector housing 2 after the connector terminal 3 has been inserted into the connector housing 2.
    [0024] When the connector terminal 3 is inserted into the first space 22 through the opening 23 of the connector housing 2, as shown in FIG. 16A, the projection 24 enters the connector terminal 3 through the opening 40 of the terminal body 4, and the upper surface 24a of the projection 24 faces the space 50 of the elastic part 5 housed in the terminal body 4. By further inserting the connector terminal 3, as illustrated in FIG. 16B, the sliding portion 52 of the elastic piece 5 comes into contact with the inclined upper surface 24a of the projection 24, and is then pushed along the inclined upper surface 24a towards the second space 21. As a result, the portion contact 55 of the elastic part 5 is forced to protrude into the second space 21 from the first space 22 through the opening 25. As shown in FIG. 16C, when the sliding part 52 of the elastic part 5 beyond a lower end of the inclined upper surface 24a of the projection and reaches a lower surface 24b of the projection 24, the contact portion 55 of the elastic piece 5 which has passed into the second space 22 through the 25 is placed in a condition such that the sliding portion 52 can come into contact with the terminal 240 formed on the printed circuit board 210 to be inserted into the second space 21. Below is explained a process of assembly of the printed circuit board 210 in the connector 1 assembled in the manner mentioned above, with reference to FIGS. 17A and 17B. Fig. 17A is a sectional view showing a positional relationship between the connector 1 and the printed circuit board 210 before the printed circuit board 210 is fully inserted into the connector housing 2, and Fig. 17B is a view of section showing a positional relationship between the connector 1 and the printed circuit board 210 after the circuit board 210 is inserted into the connector housing 2. The housing 230 holding the printed circuit board 210 therein is inserted into the cover 20 of the connector housing 2 in which the connector terminal 3 is inserted. Thus, as shown in FIG. 17A, the printed circuit board 210 enters the second space 21 of the connector housing 2. Then, as shown in FIG. 17B, the contact portion 55 of the elastic part 5 which has passed in the second space 21 through the opening 25 makes a mechanical and electrical contact with the terminal 240 of the printed circuit board 210. In the embodiment, the connector terminal 3 is inserted into the first space 21 of the connector housing 2 through the opening 23, and then the contact portion 55 of the elastic part 5 is pushed to thereby pass into the second space 21 of the first space 22 through the opening 25. Thus, the The contact portion 55 is in a condition such that the contact portion 55 can contact terminal 240 of the printed circuit board 210 to be inserted later in the second space 22. When the circuit board printed 210 is inserted into the second space 21, the contact portion 55 actually contacts the terminal 240 of the printed circuit board 210. Thus, if the terminal body 4 was designed to have a space in which the elastic piece 5 can be accommodated, it would be possible to have a gap in the elastic part 5 to allow the projection 24 of the connector housing 2 to enter, thereby reducing the size of the connector terminal 3, and therefore the connector 1 enclosing the connector terminal 3. In the connector 1 according to the embodiment, as has been explained so far, when the printed circuit board 210 is inserted in the second space 21 of the connector housing 2, the contact portion 55 of the elastic piece 5 protruding into the second space 21 through the opening 25 is pushed towards the first space 22, and the first portion 51 of the elastic piece 5 is elastically deformed e. As a result, a reaction force provided by the first portion 51 provides a high contact load between the contact portion 55 of the elastic piece 5 and the terminal 240 of the printed circuit board 210, and in this case, since an internal force of the elastic part 5 is divided into three sections, more especially the contact part 55, the first part 51, and the curved part 54, the elastic part 5 is prevented from being plastically deformed, and the Connector terminal 3 may therefore have improved durability. If the elastic part 5 is designed not to include the curved part 54, since the second flat part 53 comes into contact with an inner surface of the terminal body 4, an internal force of the elastic part 5 is divided into only two sections, more particularly the contact portion 55 and the first portion 51. Therefore, the elastic piece 5 without the curved portion 54 would have a greater maximum force than that of the elastic piece 5 having the curved portion 54. When the printed circuit board 210 is inserted into the second space 21 of the connector housing 2, the contact portion 55 of the elastic part 5 is pushed towards the first space 22 or the opening 25 from the second space 21, especially pushed in the condition illustrated in Figure 17B from the condition illustrated in Figure 17A. As a result, although the first curved or arcuate portion 51 is forced to withdraw toward the opening 23, the abutment 45 located at the rear of the sheath portion 41 prevents withdrawal of the first portion 51 of the workpiece. elastic 5. Thus, the distal end 5b and the sliding portion 52 of the elastic piece 5 are prevented from being drawn in the second space 21 to be so deformed when the printed circuit board 210 is inserted into the second space 21, which provides an improvement in reliability for the contact between the connector terminal 3 and the printed circuit board 210. INDUSTRIAL APPLICATION The present invention is useful for a connector terminal and a connector both used for electrical connection between devices. mounted in an automobile and so on.
