Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an IC card connector incorporated in an electronic information device or the like.

[0002]

[Prior Art]

 Conventionally, an IC card connector is composed of a connector main body that receives a terminal portion at the tip of the IC card and an IC card insertion guide provided on the front side of the connector main body. Here, the insertion guide is abbreviated as an IC card. It is generally composed of a resin molded product that is integrally formed with rail portions having guide grooves that match each side edge portion of the IC card on both sides of the upper surface of the base plate portion having the same width.

[0003]

[Problems to be solved by the device]

 By the way, recently, electronic information devices have become thinner, and it is required to make IC card connectors incorporated therein as thin as possible. However, as in the prior art, the insertion guide is made of synthetic resin. In order to secure the formability and strength of the base plate, it is difficult to make the thickness of the base plate so thin that it is difficult to make the connector below a certain limit. Has become. In view of the above points, the present invention has an object to provide an IC card connector that can be made thinner by changing the structure of the insertion guide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an insertion guide for an IC card, which comprises a connector body for receiving a terminal portion at the tip of the IC card and an IC card insertion guide provided on the front side of the connector body. Is a rail member on both sides having matching guide grooves on both side edges of the IC card, and a connecting plate made of a thin metal plate that holds both rail members across the rail members. It is characterized by being configured.

[0005]

[Action]

 Since the connecting plate that holds both rail members is made of metal, strength can be ensured even if the connecting plate is thinner than the base plate portion of the conventional insertion guide made of a synthetic resin integrally molded product. By making the connecting plate thin, the insertion guide and thus the entire connector can be made as thin as possible.

【Example】

 Referring to FIGS. 1 and 2, reference numeral 1 is a synthetic resin connector body that receives a terminal portion at the tip of an IC card, and 2 is an IC card insertion guide provided on the front side of the connector body 1. 3 is inserted into the end wall 10 of the connector body 1 by guiding the insertion guide 2 to a position where the terminal portion A1 at the tip of the IC card A fits into the connector body 1 as shown in FIG. The male contact 11 is fitted and connected to the female contact embedded in the terminal portion A1.

On the upper surface of the connector main body 1, an eject plate 3 having a pair of claw pieces 3 a protruding into the main body 1 through elongated holes 12 formed on both sides of the upper surface of the main body 1, and one end The lever 4 engaged with the central cut 3b of the eject plate 3 is provided, and the other end of the lever 4 is engaged with the tip of the operating rod 5 extending from the insertion guide 2 side to lock the lock. The lever 4 is rotated counterclockwise in FIG. 1 around the fulcrum portion 13 on the upper surface of the end wall portion 10 of the connector body 1 by the pressing operation of the door 5, and this rotation causes the eject plate 3 to move to the front side. The IC card A was slid to the side and pushed out toward the front side through the claw piece 3a. As shown in FIGS. 3 and 5, the end wall portion 10 of the connector body 1 is formed slightly lower than the upper surface of the connector body 1 with which the eject plate 3 is slidably contacted, and the lower surface of the eject plate 3 and the end wall portion 10 are formed. The lever 4 can be interposed between the lever 4 and the upper surface of the lever 4, and the escape groove 14 for the cut 3b is formed in the central portion of the upper surface of the end wall portion 10 and the portion on the front side thereof. The entire ejecting mechanism including is included within the dimension of the thickness of the connector body 1 plus the thickness of the eject plate 3. Further, projections 15 projecting forward are formed on both sides of the connector body 1, and mounting brackets 16 for fixing the connector body 1 to a circuit board inside the body of an electronic information device or the like are fixed to the respective projections 15. At the same time, a convex portion 17 for positioning with respect to the circuit board is provided on the lower surface of the connector body 1, and a pair of rail portions 18 extending to the labor side are extended on both side portions of the connector body 1. The rail portion 18 is formed with a guide groove 18a adapted to the side edge portion A2 of the IC card A.

As shown in FIGS. 1, 4 and 5, the insertion guide 2 is made of a pair of rail members 20 and 21 made of synthetic resin, and a metal member that holds both rail members 20 and 21 across them. And the guide plates 20a and 21a, which are adapted to the side edge portions A2 on both sides of the IC card A, are formed in the rail members 20 and 21, respectively. The fitting pieces 20b and 21b are integrally extended, and the engagement pieces 20b and 21b are engaged with the engagement grooves 18b formed on the outer side surface of the rail portions 18 formed in the connector body 1 to insert the insertion guide 2 into the connector body. The guide grooves 20a, 21a of each rail member 20, 21 and the guide groove 18a of each rail portion 18 are aligned in a straight line in this connection state.

The connecting plate 22 has a claw piece 22a that is inserted and locked in the vertical through holes 20c and 21c formed in the rail members 20 and 21 and is cut and raised downward. Both side portions are bent downward along the outer surfaces of the rail members 20 and 21, and projections projecting on the outer surfaces of the rail members 20 and 21 are provided at the bent portions (projection 21d of the rail member 21 in the drawing. The engaging holes 22b are formed so as to engage with the rails 20 and 21 with the claw pieces 22a and the engaging holes 22b. Reference numeral 22c in the drawing denotes an attachment portion to the circuit board formed on the lower edge of the bent portion of the connecting plate 22. The rail member 21 on one side is formed wide, and a through hole 21e penetrating in the front-rear direction is formed in an outer portion of the rail member 21, and the operation rod 5 is inserted therein.

By the way, in the insertion guide made of an integrally molded product of synthetic resin as in the above-mentioned conventional example, the thickness of the base plate portion needs to be about 1 mm in order to secure moldability and strength, but it is made of metal. The connecting plate 22 has a strength of about 0.3 mm, and the thickness of the connector can be reduced by about 0.7 mm as compared with the conventional one. The thinning of each component built into electronic information equipment on the order of about 0.1 mm also contributes significantly to the thinning of the overall equipment. In practice, it is possible to make the connector as thin as 0.7 mm. The value of is great.

There are two types of IC connectors, one having the operation rod 5 for ejecting on the right side and the other having the operation rod 5 on the left side as in the above embodiment. The end wall portion 10 is provided so that the connector body 1 can be used for both types. As shown in FIG. 5, the lever fulcrum portions 13 are formed on the upper surface of the left and right as a pair, and the connecting plate 22 of the insertion guide 2 is formed symmetrically in the front-rear direction. The right type rail members 20 and 21 and the pair of left type rail members which are mirror-symmetrical for the left type are also connected to each other so that the connecting plate 22 is commonly used.

[0012]

[Effect of the device]

 As is clear from the above description, according to the present invention, a connector as thin as possible can be obtained, which greatly contributes to the thinning of a device incorporating the connector.
