US Pat. No. 5,779,494

  When the IC card is inserted into the connector, first, the IC card is inserted into the fixing groove of the insulator at an inclined angle, and then rotated downward to expand the guide arm outward. Thus, the IC card is mounted in the fixing groove, and the guide arm is recovered by its own elasticity.

  However, since the IC card must be inserted and removed at all times as necessary, the force acting on the guide arm affects the connection between the connector and the printed board. In particular, when the IC card is rotated downward, the front end of the IC card generates an upward force acting on the conductive terminal. This affects the soldered connection between the conductive terminal and the printed circuit board. Therefore, there is a need to develop a new type of connector in order to solve such a problem.

  An object of the present invention is to provide a connector that is stably fixed to a printed circuit board and stably connects an IC card or the like to the printed circuit board.

  In order to achieve the above object, the connector of the present invention includes an insulator, a plurality of conductive terminals, and a fixing member. The insulator includes a base having an insertion groove into which an IC card is inserted. The conductive terminal includes a contact portion that extends into the insertion groove and a contact leg that protrudes from the base of the insulator. In the connector, when the IC card is rotated and inserted into the insertion groove by the fixing member mounted on the insulator, the force received by the conductive terminal is balanced.

  Compared with the prior art, the present invention has the following advantages. That is, the connector is stably mounted on the printed circuit board by the fixing member mounted on the insulator, and thus, an electrical stable connection by the connector between the IC card and the printed circuit board is achieved. It is.

  The connector 100 of the present invention will be described with reference to FIGS. The connector 100 of the present invention is mounted on a printed circuit board 7 for inserting and connecting an IC card or the like, and includes an insulator 1, a plurality of conductive terminals 2, a pair of holding fittings 3, and a fixing member 4.

  As shown in FIGS. 2 and 4, the insulator 1 is formed in a U shape, and includes a base body 10, end portions 14 provided at both ends in the longitudinal direction of the base body 10, and both end portions 14, respectively. A pair of opposed guide arms 13 extended, an insertion groove 11 formed along the longitudinal direction of the base body 10, and provided parallel to the inner wall (no symbol) opposite to the top and bottom of the insertion groove 11. A plurality of receiving grooves 12 formed therein.

  The guide arm 13 of the insulator 1 has a base 131 parallel to the printed circuit board 7 (shown by a broken line in FIGS. 3 and 4), and extends perpendicularly to the base 131, and is located outside the insulator 1. A vertical portion 132 positioned; a locking portion 133 having a semi-cylindrical shape formed at a tip of the vertical portion 132; a convex portion 134 protruding from an upper edge of the vertical portion 132; the vertical portion 132; It includes a slit 135 formed between the end portion 14 and a recess 136 formed at the tip of the base portion 131.

  The conductive terminal 2 is mounted in the receiving groove 12 and includes an upper row terminal in the receiving groove 12 provided in the upper inner wall and a lower row terminal in the receiving groove 12 provided in the lower inner wall. The shape and configuration of the upper row terminal and the lower row terminal that are installed opposite to each other are similar. Each upper row terminal includes a contact portion 21a, a fixing portion 22a, and a contact leg 23a, and each lower row terminal includes a contact portion 21b, a fixing portion 22b, and a contact leg 23b.

  The contact portions 21a and 21b extend into the insertion groove 11, and are elastic to the upper surface 61 and the lower surface 62 of the IC card 6 (shown by broken lines in FIG. 4) inserted into the insertion groove 11, respectively. Can be connected. At this time, the contact portion 21a of the upper row terminal is located behind the contact portion 21b of the lower row terminal, which is advantageous when the IC card 6 is rotated and inserted. The fixing portions 22a and 22b are engaged and fixed in the insulator 1, respectively, and the contact legs 23a and 23b protrude on both sides (no symbol) of the insulator 1 and are soldered to the surface of the printed circuit board 7, respectively. The contact leg 23a of the upper row terminal is located behind the insertion groove 11, and the contact leg 23b of the lower row terminal is located in front of the insertion groove 11.

  The pair of holding metal fittings 3 are mounted on the pair of opposed guide arms 13 and formed by punching from a metal plate. The main body 31 has a rectangular main body 31 and extends rearward from the main body 31 to both sides (no symbol). ), An engaging portion 32 having a plurality of convex piercing portions 321, a first convex piece 33 and a second convex piece 34 formed so as to extend from the upper edge of the main portion 31, A third projecting piece 35 and a soldering piece 36 formed so as to extend from the lower edge, and an elastic piece 37 extending to a position close to the soldering piece 36 are included.

  The holding metal fitting 3 is engaged and fixed in the slit 135 of the guide arm 13 by a piercing portion 321 provided in the engaging portion 32. At this time, the main body portion 31 is brought into close contact with the outside of the vertical portion 132 of the guide arm 13, the first convex piece 33 is located above the locking portion 133, wraps the tip of the vertical portion 132, The second convex piece 34 presses the convex part 134, and the third convex piece 35 is freely moved into the concave part 136 of the guide arm 13 and mounted. Thus, in the process of inserting the IC card 6, the holding metal fitting 3 can prevent the guide arm 13 from being excessively shifted and serves to protect the guide arm 13. The elastic piece 37 is located above the base 131 of the guide arm 13 and is connected to a grounding device (not shown) of the IC card 6 to form a ground route.

  As shown in FIG. 5, the fixing member 4 is attached to the end portion 14 of the insulator 1 in a fixing portion 15 formed so as to extend from the front end to the rear end, and is attached to the rear end of the insertion groove 11. It is located and used for mounting the connector 100 on the printed circuit board 7. The end portion 14 is formed with a through hole 16 that vertically penetrates the fixing portion 15. In the present embodiment, the fixing member 4 is a nut mounted in the fixed portion 15 and a bolt mounted in the through hole 16. Of course, the fixing part 15 may be formed in a shape recessed on both sides of the end part 14.

  When the IC card 6 is mounted in the connector 100, as shown in FIGS. 3 and 4, first, the IC card 6 is inserted obliquely into the insertion groove 11, and then downward (see r in the figure). It is pressed so as to be rotated in the direction shown in FIG. Further, when the guide arm 13 is expanded outward by elasticity and the IC card 6 is mounted on the base 131 of the guide arm 13, the guide arm 13 can be recovered by elasticity. The IC card 6 is restricted in movement in the front-rear and left-right directions by engaging the engaging portions 133 with concave portions (not shown) on both sides of the IC card 6, and the convex portions 134 Movement in the direction of is limited. When removing the IC card 6 from the connector 100, the guide arm 13 is expanded outward by an external force, and then the IC card 6 is removed from the connector 100.

  In the process of inserting / removing the IC card 6, the connector 100 receives an external force, but since the conductive terminal 2 is only soldered to the printed circuit board 7, it is easily detached from the printed circuit board 7. However, in the present invention, the connector 100 is reliably mounted on the printed circuit board 7 by the conductive terminal 2 and the fixing member 4, and the separation from the printed circuit board 7 is prevented. Further, when the card 6 is rotated downward, the conductive terminal 2 receives an upward force (in the direction indicated by u in the figure), but the upward force is balanced by the fixing member 4. Thus, the connection of the contact leg 23a of the conductive terminal 2 to the printed circuit board 7 cannot be broken. Thus, an electrically stable connection between the IC card 6 and the printed circuit board 7 is achieved.

  Of course, the holding metal fitting 3 may be directly attached to both ends 14 of the insulator 1. In addition, since the said effect can be achieved if the said holding | maintenance metal fitting 3 consists of plastic products, it does not restate.

  As mentioned above, although this invention was demonstrated in detail with reference to best embodiment, embodiment is only an illustration to the last and is not limited to these.
