However, the above-mentioned card connector often provides insufficient plugging force, so that the electronic card is easy to come out of the card connector.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the above-mentioned prior art, and provide a plug connector that can make the plugging force and holding force of the docked socket connector more stable, and the plugging operation is more convenient.

To achieve the above object, the utility model provides a card connector, which includes an insulating body, several terminals and at least one elastic piece. The insulating body is provided with several terminal slots, and a slot is provided at both ends of the upper side of the insulating body, and the part of the insulating body between the two slots forms a boss portion, and at least one of the slot walls is provided with a fastening slot; Several terminals are placed in several terminal grooves of the insulating body; the shrapnel is installed in the slot of the insulating body, and has a convex arch, an elastic portion extending outward from the convex arch, and a bending and extending form of the elastic portion. The fastening part is fastened in the fastening groove of the insulating body.

As mentioned above, the card connector of the present invention adopts the design of the elastic piece, and the convex arch of the elastic piece can elastically abut against the electronic card or the card holder for accommodating the electronic card, so that the card connector can provide sufficient insertion force.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the card connector 100 of the present invention includes an insulating body 10 , a plurality of terminals 20 , at least one elastic piece 30 and a card seat 40 .

Please refer to FIG. 2 and FIG. 3 , the insulating body 10 is in the shape of a rectangular block. The insulating body 10 is provided with several terminal grooves from the front and rear edges inwardly. The receiving groove 11 that runs through the top wall and the bottom wall of the insulating body 10 and the holding groove 12 that is opened in the receiving groove 11 and in the middle of the insulating body 10; the upper two ends of the insulating body 10 are respectively provided with a slot 13, The part between the two slots 13 of the insulating body 10 forms a boss portion 14, the groove wall of the slot 13 is provided with a fastening groove 141, and the bottom wall of the insulating body 10 corresponds to the fastening groove 141. The locking groove 15 communicates with the fixing groove 141 .

Please refer to Fig. 2, the terminal 20 is placed in several terminal grooves of the insulating body 10, the terminal 20 includes a plate-shaped holding part 21, a connection formed by extending backward from the rear end of the holding part 21 and then bending upward. part 22, an elastic arm 23 formed by bending and extending forward from the connecting portion 22, a contact portion 24 formed by protruding upward from the end of the elastic arm 23 and then bending downward and extending backward, and an elastic arm 24 bent from one end of the holding portion 21 The extended welding portion 25 and the holding portion 21 are fixed in the holding groove 14 of the insulating housing 10 , and the contact portion 24 protrudes from the upper surface of the receiving groove 11 .

Please refer to Fig. 2 and Fig. 3, the elastic sheet 30 is in the shape of an arch bridge, and is installed in the slot 13 of the insulating body 10. The elastic sheet 30 has a convex arch 31, which is formed by extending outward from the two ends of the convex arch 31. The elastic part 32 and the clamping part 33 formed by bending outward and downward from the elastic part 32, the convex arch part 31 has an insertion guide slope 311 and an extraction guide slope 312, in this embodiment, the insertion guide surface 311 The angle is different from that of the pull-out guide slope 312 , so that the card connector 100 has a small insertion force and a large pull-out force. A card 331 obliquely extends inwardly from the fastening portion 33 , the fastening portion 33 is fastened in the fastening groove 14 of the insulating body 10 , and the card 331 is fastened on the top wall of the buckling groove 15 of the insulating body 10 .

Please refer to Fig. 1 and Fig. 4, the described holder 40 can be matched with the insulating body 10 in a relatively slidable manner. There is a through groove 43 that runs through the bottom wall and extends to one end of the base body 41. A groove 44 is respectively recessed on both sides of the bottom wall of the base body 41. The boss portion 14 extends into the through groove 43. The convex arch of the elastic piece 30 The portion 31 can be elastically inserted into and disengaged from the groove 44 .

In the card connector of the present utility model, when the electronic card is inserted, the electronic card is placed in the through groove 42 of the card holder 40 first, and the card holder 40 is inserted along the extension direction of the elastic piece 30 until the convex arch portion 31 of the elastic piece 30 is locked. Fit in the groove 44 of the card holder 40 , when the electronic card is taken out, the card holder 40 is pulled to make the convex arch 31 escape from the groove 44 .
