The connector body 10 is made of a synthetic resin molded product, and an insertion opening 10a for the memory 1 is provided at one end thereof. A hole 11 for accommodating the stopper 30 is provided on one end side in the width direction of the connector body 10, and the hole 11 is formed to have a width for receiving one end side in the width direction of the memory 1 inserted into the connector body 10.

The terminals 20 are arranged in the width direction of the connector body 10, and one end side of the terminals 20 is projected from the other end side of the connector body 10. Although not shown, each terminal 20
The other end of the connector extends into the connector body 10 and
The memory 1 inserted in 0 is brought into pressure contact while sliding.

The stopper 30 is composed of a plate-shaped spring extending in the insertion direction of the memory 1, and its base end portion 31 is fixed in the hole 11 of the connector body 10. The tip portion 32 of the stopper 30 is bent in a substantially U-shape so as to project in the width direction, and its rear surface side (base end portion 31 side of the stopper 30) is formed so as to be locked to the connector body 10 side. There is. That is, in the hole 11 of the connector body 10, as shown in FIG. 5 (a), there is provided a locking portion 11a which is close to the tip portion 32 of the stopper 30 with a slight clearance, and the locking portion 11a is a stopper. Three
It is opposed to the front end 32 of 0 so that it can be locked. Further, the stopper 30 has a distal end portion 32 formed slightly larger than the proximal end portion 31 side in the thickness direction of the connector body 10, and is equivalent to the distal end portion 32 from the proximal end portion 31 side as shown in FIG. Reinforcing part 32 extending by a predetermined length in the thickness direction of the
a.

In the electrical connector constructed as described above, the memory 1 is inserted from the insertion opening 10a of the connector body 10.
When the memory card 1 is inserted, the memory 1 is brought into pressure contact with each terminal 20 while sliding, and each terminal 20 and a conductive portion (not shown) of the memory 1 are electrically connected and electrically connected to each other. The memory 1 is held in the connector body 10 by the pressure contact force. At that time, when the memory 1 is inserted in an appropriate direction, the inclined portion 1a provided on one end side in the width direction of the memory 1 abuts on the tip portion 32 of the stopper 30, and the inclined portion 1a causes the tip portion 32 of the stopper 30. Is guided to one side in the width direction of the connector body 10 to allow the insertion of the memory 1. Further, when the memory 1 is inserted in an improper orientation (for example, the front and back are opposite), the tip 32 of the stopper 4 is inserted as shown in FIG. 5 (b).
Since the portion of the memory 1 where the inclined portion 1a is not provided abuts, the tip end portion 32 of the stopper 30 does not move in the width direction, and further insertion of the memory 1 is restricted. At that time, even if an excessive insertion force is applied to the stopper 30,
As shown in FIG. 5B, since the tip end portion 32 of the stopper 30 is locked to the locking portion 11a of the connector body 10, the stopper 30 is not deformed in the inserting direction of the memory 1.

As described above, according to the electrical connector of this embodiment, when the excessive insertion force of the memory 1 inserted in an improper direction is applied to the stopper 4, the tip portion 32 of the stopper 30 is inserted into the connector body 10. Since the stopper 30 is engaged with the engaging portion 11a provided on the side, the stopper 30 is prevented from being disengaged from the connector body 10 or deformed due to compression in the longitudinal direction, and the stopper 30 is reliably prevented from being damaged. You can

Further, the front end portion 32 of the stopper 4 is connected to the base end portion 3
Since the reinforcing portion 32a is formed to be slightly larger than the one side and extends from the tip end portion 32 to the base end portion 31 side by a predetermined length, the strength of the tip end portion 32 can be increased and the tip end portion 32 of the stopper 30 can be increased. It is possible to reliably prevent the deformation of the front end portion 32 from the contact of the memory 1 with the front end portion 32 until the front end portion 32 is locked to the locking portion 11a of the connector body 10.

[0019]

As described above, according to the electric connector of the first aspect, even if an excessive insertion force of the connection object inserted in an improper direction is applied to the stopper, the stopper is removed from the connector body. Since it does not come off or is not deformed due to compression in the longitudinal direction, damage to the stopper can be reliably prevented.

According to the electric connector of claim 2,
In addition to the effect of claim 1, since the strength of the distal end portion of the stopper can be increased, the distal end from the contact of the connection target object to the distal end portion of the stopper until the distal end portion is locked to the locking portion of the connector body.
