    [0001] The invention relates to a connector terminal to be used for electrical connection between devices mounted in an automobile and so on, and more particularly to a connector terminal to be inserted into a connector in which a card comprising a terminal portion at a border area on a surface thereof is also inserted.
    [0002] For example, Japanese Patent Application Publication No. 2003-7369 discloses a connector in which a card having a terminal portion at an edge region on a surface thereof is inserted. Fig. 7 is a perspective view of a connector terminal metal contact disclosed in the aforementioned publication, Fig. 8 is a sectional view of a housing in which the terminal metal contact is inserted, and a second connector into which the housing is to be inserted, and Fig. 9 is a sectional view of the housing and the second connector into which the housing is inserted. A terminal metal contact 100 illustrated in FIG. 7 is assembled in a card edge connector 110, as shown in FIG. 8. As shown in FIGS. 8 and 9, the card edge connector 110 is mounted in a cover 121 of a second connector 120. In a condition in which the card edge connector 110 is inserted into the cover 121, as shown in FIG. 9, a card 122 is inserted at a portion thereof in a mounting space 112 of a housing 111, and is clamped between resilient contact pieces 101 of the terminal metal contacts 100 above and below the card 122 to elastically deforming the elastic contact pieces 101. Thus, the elastic contact pieces 101 establish an elastic contact with upper and lower surfaces of the card 122 with a certain contact pressure resulting from forces 5 of resilient return thereof, and thereby establish mechanical and electrical contact with a terminal portion formed at an edge region on the surface of the board 122. The resilient piece 101 is substantially in the form of A substantially U-shaped semicircular portion of the resilient piece 101, when in a free condition in which it is not elastically deformed, defines a contact portion 101A protruding upward beyond the edges upper side walls 102L and 102R. The contact portion 101A makes an elastic contact with the upper or lower surface of the card 122. Such a connector wherein the card comprising the terminal portion at the edge region on the surface thereof is inserted is accompanied by a problem in that, if the card 122 of the second connector 120 is not chamfered at the front corners, the contact portion 101A can be planed on a surface when the contact portion 101A of the elastic piece 101 Advancing the surface of the board 122. If the contact portion 101A were planed at its surface, the contact portion 101A would establish an unstable contact with the board 122, resulting in an increase in contact resistance between they and an electrical connection unstable between them. Due to the aforementioned problem in the conventional electrical connector, it is an object of the present invention to provide a connector terminal 3025364 capable of preventing a contact portion from being planed by a leading edge of a connector. card to be inserted into a connector, in order to make a stable connection between a contact portion and a terminal portion of the card, and further to prevent a contact resistance from increasing at the contact portion, and to make a stable electrical connection between the contact portion and the card. In one aspect of the present invention there is provided a connector terminal to be inserted into a connector and to electrically connect to a terminal portion formed in an edge region of a surface of a card inserted in the connector. the connector terminal comprising an inclined portion which inclines with respect to the card inserted in the connector, the inclined portion being elastically deformable when compressed by the card, at least one contact portion formed on the inclined portion and making contact with the terminal portion of the card, and at least one protruding portion formed on the inclined portion and making contact with the card prior to the contact portion when the card is inserted into the connector, the protruding portion, when the card is inserted into the connector, making contact with one edge of the card, then passing over the terminal portion of the card, and then, lifting itself away from the terminal portion of the card when the contact portion makes contact with the terminal portion of the card. In the connector terminal according to the present invention, when the card is inserted into the connector, the projection makes contact with the front edge of the card earlier than the contact portion, and then advances on a terminal portion of the connector. the map. When the card is inserted further into a connector, the contact portion makes contact with the leading edge of the card, and then advances to the card, in which case, since the protruding portion first makes contact with the card to elastically deform the inclined portion, the inclined portion tilts with a lower inclination angle than before. In addition, since the inclined portion is elastically deformed to a smaller degree than before when the contact portion advances on the card, the contact portion can advance on the card with a reduced load, making possible the fact of prevent the contact portion from being planed by the front edge of the card inserted into the connector. On the other hand, when the contact portion makes contact with the terminal portion of the card and then advances therethrough, the protrusion is caused to be away from the terminal portion of the card, and thus , only the contact portion makes contact with the terminal portion of the card, providing a stable contact between the contact portion and the terminal portion of the card.
    [0003] It is preferable that the projecting portion has a curved surface. By so conceiving, the protruding part can make a smooth contact with the board and then move on it when the board is inserted into the connector, making it possible to reduce a resistance with which the projecting part advances on the board. map. It is preferred that the contact portion and the protrusion be located so as not to overlap when viewed in a direction in which the card is inserted into the connector. By so conceiving, it is possible to cause the protruding portion to make contact with the card in a location other than the terminal portion with which the contact portion makes contact when the card is inserted into a connector, such that making it possible to prevent the projection from making contact with and causing damage to the terminal portion of the card with which the contact portion makes contact. For example, the connector terminal may be adapted to include a contact portion and two projections, the projections each located outside the contact portion when viewed in a direction in which the card is inserted in the connector. For example, the connector terminal may be designed to include two contact portions and a protrusion, the contact portions being located each outside the protruding portion when viewed in a direction in which the card is inserted in the connector. The advantages obtained by the present invention mentioned above will be described below.
    [0004] The connector terminal according to the present invention is adapted to include the inclined portion which inclines relative to the card inserted in the connector, the inclined portion being resiliently deformable when compressed by the card, at least a portion contact formed on the inclined portion and making contact with the terminal portion of the card, and at least one projection formed on the inclined portion and making contact with the card prior to the contact portion when the card is inserted into the 30 connector, the protruding portion, when the card is inserted into the connector, making contact with an edge of the card, then passing on the terminal portion of the card, and then lifting away from the terminal portion of the card when the contact portion makes contact with the terminal portion of the card. The connector terminal prevents the contact portion from being planed by the front edge of the card inserted into the connector, ensuring stable contact between the contact portion and the terminal portion of the card, and thereby preventing a contact resistance at the contact portion to increase, and making a stable electrical connection between the contact portion and the card. By designing the protruding portion with a curved surface, it is possible to reduce a resistance with which the projecting portion rises on the board when the board is inserted into the connector, ensuring that the board can be smoothly inserted into the board. connector. By designing the contact portion and the projecting portion so that they do not overlap when viewed in a direction in which the card is inserted into the connector, it is possible to prevent the projecting portion from being damaged. the terminal portion of the card making contact therewith with which the contact portion makes contact when the card is inserted into the connector. It is further possible to prevent a contact resistance at the contact portion from increasing, and to provide a stable electrical connection between the contact portion and the card.

[First Embodiment] Fig. 1 is a sectional view of a connector comprising a connector terminal according to a first embodiment of the present invention; Fig. 2 is a perspective view of the connector terminal illustrated on FIG. 1 when viewed obliquely from below, and FIG. 3 is an enlarged view of a portion A shown in FIG. 2. In FIG. 1, a connector 1 comprises a connector terminal 2 according to FIG. the first embodiment, a card 3, and a connector housing 10. The card 3, which includes a terminal portion 3A formed at an edge region on a surface thereof, is inserted into the connector housing 10 in which the connector terminal 2 according to the first embodiment is also inserted. The connector terminal 2 is inserted into the connector housing 10 through an opening 11 formed at a rear end (on a right side in FIG. 1) of the connector housing 10, and is fixed in the connector housing. 10 by means of a retaining element 12 so as not to be withdrawn from the connector housing 10 through the rear end of the connector housing 10. The card 3 is inserted into the connector housing 10 through an opening 13 formed at a front end (on a left side in FIG. 1) of the connector housing 10. In the description, the term "forward" is forward of a direction X in which the card 3 is inserted into the connector housing 10, and the term "backward" is rearward of the X direction.
    [0008] Connector terminal 2 is made by treating an electrically conductive flat sheet. The connector terminal 2 comprises a terminal body 20 for clamping the card 3, a cable attachment section 21 at which a cable 4 is compressed, and a cable holder 22 through which the cable 4 is assembled. The terminal body 20 comprises a resilient contact portion 23 providing resilient contact with the terminal portion 3A of the card 3, and a card receiver 24 disposed opposite the resilient contact portion 23.
    [0009] The card 3 is clamped between the resilient contact portion 23 and the card receiver 24. As shown in FIG. 3, the resilient contact portion 23 comprises an inclined portion 25 which is resiliently deformable when it is compressed by the card 3, a contact portion 26 formed on the inclined portion 25 and making contact with the terminal portion 3A of the card 3, and two projections 27 formed on the inclined portion 25.
    [0010] The inclined portion 25 is formed by folding a stripped portion forward (the right side in FIG. 1) of the X direction. That is, the sloping portion 25 extends in the X direction from a base portion 20A located at a rear end (left side in Figure 1) of the terminal body 20 so that a front end (the right side in Figure 1) thereof is close Thus, the inclined portion 25 inclines relative to the card 3 inserted in the connector housing 10. The inclined portion 25 is then folded at its forward end in a direction away of the card 3 (upwards in FIG. 1), and further folded towards the rear of the direction X. The contact portion 26 is disposed on a folded portion of the inclined portion 25 at the end before the inclined portion 25. The projecting portions 27 protrude downwards, and are more p The protruding portions 27 have a curved cross-section, and have a smooth surface. The contact portion 26 and the projections 27 are provided to be arranged so as not to overlap when viewed in the X direction.
    [0011] When viewed in the X direction, the contact portion 26 is disposed between the projecting portions 27. Figures 4A-4C are enlarged sectional views which each illustrate a step of inserting the card 3 into the connector terminal 2. As shown in FIG. 4A, when the card 3 is inserted in the connector terminal 2, the card 3 first establishes a contact, at a front edge 3B thereof with protruding portions 27 to resiliently deform the inclined portion 25 upwardly. Thus, the projecting portions 27 advance or pass over an upper surface of the card 3. When the card 3 is further inserted into the connector terminal 2 as shown in FIG. 4B, the contact portion 26 makes contact with the leading edge 3B of the card 3, and then, as shown in FIG. 4C, passes on the upper surface of the card 3 Since the protruding parts 27 established First contact with the card 3 to elastically upwardly deflect the inclined portion 25, the inclined portion 25 inclines with an inclination angle smaller than a first inclination angle. Further, the inclined portion 25 is resiliently deformed to a smaller degree as the contact portion 26 passes over the upper surface of the card 3. This reduces a load on the contact portion 26 when the contact portion 26 passes on the upper surface of the card 3, which prevents the contact portion 26 from being planed by the leading edge 3B of the card 3 inserted into the connector terminal 2. As shown in FIG. 4C, when the contact portion 26 passes on the terminal portion 3A of the card 3, the projecting portions 27 rise away from the terminal portion 3A of the card 3. Thus, since only the contact portion 26 establishes a contact with the terminal portion 3A of the card 3, the contact portion 26 can establish a stable contact with the terminal portion 3A of the card 3, which prevents an increase of a contact resistance at the part contact 26 in order to achieve a co Stable electrical connection between the card 3 and the connector terminal 2. Furthermore, since the projecting portions 27 of the connector terminal 2 according to the first embodiment are designed to be curved in shape and to have a smooth surface, the protruding portions 27 can make a smooth contact with the card 3 and smoothly pass to the card 3 when the card 3 is inserted into the connector terminal 2. Thus, it is possible to reduce a resistance with which the projections 27 pass through the card 3, making sure that the card 3 can be inserted smoothly into the connector terminal 2. In the connector terminal 2 according to the first embodiment, the contact portion 26 and the protruding portions 27 are provided to be arranged so as not to overlap when viewed in the X direction. The projections 27 thereby make contact with a portion of the card 3 other than the terminal 3A of the card 3 with which the contact portion 26 makes contact while the card 3 is inserted into the connector terminal 2. This prevents the projections 27 from making contact with and causing damage terminal portions 3A of the card 3 with which the contact portion 26 makes contact. [Second Embodiment] Fig. 5 is a perspective view of the connector terminal in a second embodiment, and Fig. 6 is an enlarged view of a portion B shown in Fig. 5. The terminal of Connector 2 according to the first embodiment mentioned above is designed to include a contact portion 26 and two protrusions 27, wherein the contact portion 26 is disposed between the projections 27 when viewed in the direction X. As illustrated in FIGS. 5 and 6, the connector terminal according to the second embodiment is adapted to include two contact portions 26 and a projection 27. The projection 27 is closer to the 13 of the connector housing 10 as the contact portions 26. The protruding portion 27 is disposed between the contact portions 26 when viewed in the X direction. In a manner similar to the terminal in the first embodiment, the contact portions 26 and the projecting portion 27 are arranged so as not to overlap when viewed in the X direction. The connector terminal according to the second embodiment provides not only the same advantages as those provided by the connector terminal 2 according to the first embodiment, but also an additional advantage. Since the connector terminal makes contact with the card 3 at two points, i.e. at the two contact portions 26, the contact portions 26 can make contact with the terminal portion 3A of the 3 in a more stable manner than the contact portion 26 of the first embodiment INDUSTRIAL APPLICATION 3025364 13 The connector terminal according to the present invention is useful for a connector in which a card comprising a terminal portion at the level of a border area on one surface of it must be inserted. 5
