2. Description of the Related Art A portable telephone is provided with a memory IC for storing subscriber identification information. If the memory IC is fixedly connected to the portable telephone, for example, when the portable telephone is replaced with a new model, it becomes necessary to write the subscriber identification information into the memory IC of the new portable telephone. . When the owner of the portable telephone is changed, the contents of the memory IC must be rewritten.

Therefore, the subscriber identification information is stored in a SIM (Subscr
It has been proposed to write data on an IC card called an "iber Identity Module", and to fix a connector to the portable telephone so that the SIM can be attached and detached as necessary. This allows the SIM to be replaced with a new phone when the phone is replaced, and the SIM can be replaced by a new owner when the owner of the phone changes. The telephone can be used, and the work of writing or rewriting the subscriber identification information can be omitted.

A typical prior art connector for a SIM is disclosed, for example, in US Pat. No. 5,320,552. This prior art connector is:
The housing includes a rectangular plate-like housing that holds a terminal member that contacts the SIM contacts, and a rectangular plate-like cover hinged to one side of the housing. Rails are provided on both sides of the cover to guide and hold both sides of the SIM. After inserting the SIM into the rail portion and holding it on the cover, the cover is folded down into the housing, and the contacts of the SIM are pressed against the terminal members provided on the housing to make electrical connection, and this state is held by the lock mechanism. Thereby, the SIM can be mounted.

[0005] A pair of arms are formed on the cover, and a pin formed at the tip of the arm is engaged with a recess formed at a pair of corners of the housing, thereby forming the cover and the cover. A hinge connection with the housing is achieved. The recess has a long hole shape extending along the side of the housing, and a protrusion is formed near a middle portion in the longitudinal direction. When the cover is slid while the cover is lowered into the housing, the pin moves over the protrusion. This allows the cover to slide over the length of the recess.

[0006] One end position of the range of the sliding movement is an open position where opening and closing of the cover is allowed, and the other end position is a lock position where opening and closing of the cover is restricted. When the cover is in the locked position, the end portion and the pin of the cover on the opposite side, being adapted to lock piece engages which is formed in the housing, thus locking mechanism is constituted.

As shown most clearly in FIG. 8, the rear ends of the arms 51, 52 have recesses I at their lower parts for receiving the contact portions 35, 36 of the housing 1, and Contact portions 81 and 82 having an arc-shaped portion C on the upper side are provided.

FIG. 10 is a plan view for explaining an engagement state between the housing 1 and the cover 5. Rotating pins 53, 54 formed on a pair of arm portions 51, 52 of the cover 5
Is applied to the notches 21 and 22 formed in the enlarged portions 17 and 18 of the pair of arms 11 and 12 of the housing 1 and further pushed inwardly of the recesses 19 and 20, thereby mainly the cover 5 side. Arm portions 51, 52 are elastically deformed in a direction in which they are expanded, and the rotating pins 53, 54 come into engagement with the recesses 19, 20. This state is shown in an enlarged manner in FIG.

At this time, the pivot pins 53 and 54 try to stop in the deep hole D due to their elasticity. Shallow hole S
Is formed so as to be shallower as the distance from the deep hole D increases, so that when the cover 5 is slid to force the pivot pins 53 and 54 to slide into the shallow hole S, FIG. As shown, the arms 51 and 52 elastically deform outward, and exert an elastic force to restore the pivot pins 53 and 54 to the deep hole D. Therefore, in a normal state where no external force acts on the cover 5, the rotation pins 53,
Reference numeral 54 is engaged with the deep hole D.

As shown in FIGS. 1, 2 and 13, the cover side engaging claw 73 and the housing side engaging claw 31 engage the rotating pins 53 and 54 with the deep hole D. 13, they are formed at positions where they can overlap each other (see the position of the cover-side engaging claw 73 shown by a solid line in FIG. 13). In addition, the engagement release recess 32
When the cover 5 is slid and the rotating pins 53 and 54 are displaced toward the shallow hole S, the cover-side engaging claw 73 and the cover-side engaging claw 73 overlap with the housing-side engaging claw. The overlap with the base 31 is released (see the position of the cover-side engaging claw 73 shown by a two-dot chain line in FIG. 13).

Therefore, the rail portions 57, 5 of the cover 5
8 and the cover 5 with the housing 1
The guide surface 73a of the cover-side engaging claw 73 and the guide surface 31a of the housing-side engaging claw 31 contact each other. Further, when the cover 5 is pressed against the housing 1, the cover-side engaging claw 73 is moved relative to the housing-side engaging claw 31 while mainly causing the elastic support portion 72 to be elastically deformed by the mutual guidance by the guide surfaces 73 a and 31 a. The engaging claws 73 and 31 are snap-coupled to each other, and a lock state is reached in which the contact surfaces 73b and 31b face each other. That is, the cover 5 can be locked to the housing 1 by a two-stage operation of attaching the SIM to the cover 5 and lowering the cover 5 into the housing 1.

At this time, the contact portion of the SIM comes into pressure contact with the terminal fitting 15 to achieve electrical connection between them. At the same time, the spring force of the terminal fittings 15 applies a biasing force to the cover 5 and the housing 1 in a direction away from each other, so that the locked state between the cover 5 and the housing 1 is reliably maintained.

FIG. 14 is a side view showing the operation for removing the SIM step by step. When a force is applied to the cover 5 from the locked state in FIG. 14A and the cover 5 is slid toward the rear end side (hinge joint side), the contact portion 8 is formed.
1,82 recesses I are abutting portions 3 at the rear end of the housing 1.
The sliding displacement is regulated by contacting the engaging portions 5 and 36 (FIG. 14B). In this state, the cover-side engaging claws 73 of the engaging portions 61 and 62 overlap with the engagement releasing concave portions 32 (FIG. 14B). 13 (see the position of the cover-side engaging claw 73 indicated by a two-dot chain line). Therefore, the lock connection between the cover side engaging claw 73 and the housing side engaging claw 31 is released. At this time, due to the spring force of the terminal fittings 15, the cover 5 slightly rotates in the direction caused by the housing 11, and FIG.
The state shown in (c) is reached.

Thereafter, when the force applied to the cover 5 is reduced,
Due to the elastic force generated by the arms 51, 52 that are elastically deformed by the engagement of the pivot pins 53, 54 with the shallow holes S of the recesses 19, 20, the cover 5 is moved toward the distal end. And the pivot pins 53 and 54 come into engagement with the deep hole D. This state is shown in FIG. At this time, the engagement between the recesses I of the contact portions 81 and 82 and the contact portions 35 and 36 has been released, and the cover 5 is further caused to rise, and FIG.
4 (e). In this state, the SIM held on the cover 5 can be easily pulled out. The contact portions 81 and 82 and the contact portions 35 and 3 when the cover 5 is rotated with respect to the housing 1 because the contact portions 81 and 82 have the arc-shaped portion C at the upper portion.
6 does not interfere.

As described above, according to the IC card connector 100 of this embodiment, the SIM is inserted into the cover 1,
Thereafter, when the cover 1 is fallen into the housing 5, the cover 1 and the housing 5 are locked. Therefore, the attachment of the SIM can be achieved by a two-stage operation. Then, the lock can be released by sliding the cover 1 with respect to the housing 5, and the SIM can be removed by raising the cover 1 and pulling out the SIM. This SIM removal operation is a three-stage operation, but the operation of sliding the cover 1 and causing it can be smoothly performed as a series of operations, and can be said to be substantially a one-stage operation. Therefore, the removal of the SIM can be achieved by a substantially two-step operation.

As described above, according to this embodiment, the SIM can be securely mounted by a simple operation.
There is no possibility that an improper mounting of the IM will occur, and it is possible to prevent a failure caused by the improper mounting. Further, since the configuration is not complicated as compared with the conventional product, it can be produced at a cost equal to or lower than that of the conventional product.

Further, in the portable telephone equipped with the IC card connector 100 of this embodiment, the SIM can be securely mounted by a simple operation.

Although one embodiment of the present invention has been described, the present invention can be implemented in other embodiments. For example, in the above-described embodiment, the rotating pins 53 and 54 formed on the cover 5 side are replaced with the recesses 1 formed on the housing 1 side.
The hinge coupling mechanism is configured by engaging with the hinges 9 and 20, but the same hinge coupling mechanism can be configured by providing a recess on the cover side and providing a rotating pin on the housing side.

In the above-described embodiment, both the housing-side engaging claw 31 and the cover-side engaging claw 73 are formed with the guide surfaces 31a and 73a for guiding each other. Even if only one has a guide surface, both can be guided to the engaged state.

Further, in the above embodiment, the cover 5 is urged toward the lock position by the elastically deformable arm portions 51 and 52 and the recesses 19 and 22 having the shallow holes S at the unlock position. Although the urging means is constituted, the cover 5 is provided by another urging means such as a spring member.
