In addition, card insertion grooves 2 serving as tip-side card insertion holding means are provided on the inner side surfaces of the tip-side corner-side standing walls 9L and 9R.
2L and 22R are formed.
Is composed.

Then, the base side corner side standing wall portion 20L,
A spring member 36, which is an elastic member, is disposed between 20R. That is, as shown in FIG. 8 (2), the spring member 36 is provided with a locking projection 37 serving as an attachment portion at the left end of an arc-shaped spring main body 36A.
The material of the spring member 36 is a metal or a synthetic resin. The spring member 36 is provided on the left side of the locking projection 3.
7 is inserted and locked in the locking hole 34 and disposed between the base end corner side vertical walls 20L and 20R, and the top 36B of the spring main body 36A faces the front side. In this case, the spring member 3
The right end 36R of 6 is free.

The housing body 1A has a base end 1
One of the contacts 2 serving as housing-side contact means is mounted by insert molding at a position between the notch 5 and the slit 7 in FIG. These contact portions 2a protrude above the surface of the housing body 1A. Further, the connection portion 2b of the one contact 2 projects outward from the notch portion 5 of the housing body 1A.

The housing body 1A has a tip 1
The other contact 3 serving as a housing-side contact means is mounted by insert molding at a position between the notch 6 and the slit 8 in FIG. These contact portions 3a protrude above the surface of the housing body 1A. In addition, the connecting portion 3b of the other contact 3 projects outward from the notch 6 of the housing body 1A. The spring member 36 and the card insertion grooves 21L, 21R, 22L, 22R constitute card holding means.

Since the card K is the same as that in the first embodiment of the card connector described above, the same reference numerals are given and the description is omitted.

Next, the operation of the card connector A configured as described above will be described. In the card connector A, the connection portions 2b, 3b of the contacts 2, 3 provided on the housing 1 are fixed to the corresponding conductive patterns (not shown) by soldering, and are connected to a substrate (not shown). Has been implemented.

Then, as shown in FIG. 8A, the card K is tilted, and the insertion end 33 of the card K is inserted into the card accommodating portion S so as to be attached to the top 36B of the spring body 36A of the spring member 36. When the card K is pushed in, the spring member 36 is deflected so that the insertion end 33 of the card K is inserted into the card insertion groove 2 of the base corner side vertical wall portion 20L, 20R.
Insert into 1L, 21R. In this case, the insertion end 33 of the card K is guided by the guide surfaces 23L and 23R, so that insertion into the card insertion grooves 21L and 21R becomes easy.

Next, the card K is depressed, the entire card K is put into the card accommodating portion S, and the pressing force of the card K toward the insertion side is released. Moving to the front side, the corner K at the tip of this card K
-1, K-2 are inserted into the card insertion grooves 22L, 22R of the front-end corner-side standing walls 9L, 9R. In this case, since the insertion end 33 of the card K is inserted into the card insertion grooves 21L and 21R, when the card K is defeated and the entire card K is inserted into the card storage portion S, the back surface of the card K The eight-pole card-side contact portions 32a to 32h are in contact with the contact portions 2a and 3a of the corresponding contacts 2 and 3, and the card K moves by the compression reaction force of the spring member 36,
With the corners K-1 and K-2 at the front end of the card K inserted into the card insertion grooves 22L and 22R of the front-end corner-side standing walls 9L and 9R, an 8-pole card-side contact portion on the back surface of the card K. 32a to 32h contact the corresponding contact portions 2a and 3a of the contacts 2 and 3, respectively.

In this case, the left corner K-1 of the card K is
While being urged forward by the spring member 36, the card is inserted into the card insertion groove 22L of the left front corner side standing wall 9L, and the right corner K-2 of the card K is the right front corner side standing wall. The card K is inserted into the card insertion groove 22R of the section 9R.
The movement is regulated by L and 4R. For this,
In the housing 1, the movement of the card K in the front, rear, left and right directions is restricted, and the card K is locked to the housing 1.

When removing the card K from the card connector A, the above-described procedure for mounting the card K is reversed.

In the third embodiment, similarly to the first embodiment, the side walls 4L, 4R on both sides of the housing body 1A of the housing 1 along the longitudinal direction of the housing body 1A. A card holding claw (card holding portion) 15 having a guide portion 15a inclined on the upper surface is formed at two places on the inner surface side of the
The card K is pressed down, and the entire card K is inserted into the card accommodating portion S, so that the card holding claw 15 is elastically deformed. Over the card holder 15
, The card K may be held in the housing 1 by holding the card K by the card holding claws 15.

According to the third embodiment described above, the card K is inclined, and the insertion end 33 of the card K is inserted into the card accommodating portion S, and is applied to the top portion 36B of the spring main body 36A of the spring member 36. When the card K is pushed in, the spring member 36 is bent, so that the insertion end 33 of the card K is inserted into the card insertion groove 21 of the base-side corner-side standing wall portions 20L and 20R.
L, 21R, and then the card K is turned down, the entire card K is inserted into the card accommodating portion S, and the pressing force of the card K toward the insertion side is released, whereby the compression reaction force of the spring member 36 is released. Then, the card K moves to the front side, and the corners K-1 and K-2 at the front end of the card K are turned to the front end corner side vertical wall 9L,
9R into the card insertion grooves 22L and 22R, and insert the card K
Can be brought into contact with the contact portions 2a and 3a of the corresponding contacts 2 and 3, respectively.

As described above, since the card connector A according to the present invention does not have a hold cover, there is no possibility that the hold cover is deformed or damaged by an external force.
The cost can be reduced by reducing the number of parts. In addition, since the card connector A does not have a hold cover, the card connector A can be downsized, particularly, the height can be reduced, and it is possible to cope with higher-density mounting.

Incidentally, it is also possible to form an elasticity imparting portion as an elastic urging means integrally with the housing 1 by using a synthetic resin, and to make this elasticity imparting portion function similarly to the spring member 26 or the spring member 36.

In the first, second and third embodiments, the housing-side contact means are the contacts 2 and 3 which are soldered to the conductive pattern on the substrate. The card-side contact means is a contact portion of the memory element of the card K, which contacts the contacts 2 and 3, but the present invention is not limited to this, and the card K is electrically connected to the substrate side. Any card can be used.

[0078]

As described above, according to the card connector of the present invention, since there is no hold cover,
There is no danger that the hold cover will be deformed or damaged by external force, and the cost can be reduced by reducing the number of parts. In addition, since the card connector does not have a hold cover, the card connector can be downsized, particularly, the height can be reduced, and it is possible to cope with higher-density mounting.

Further, the card connector can be used for connection to a substrate of a card in which personal information and the like are stored in a storage element.
