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 to FIG. 3 , which disclose a socket connector 1 of the present invention, which includes a socket housing 11 , a socket body 12 and a plurality of socket terminals 13 held on the socket body 12 .

The socket housing 11 has a socket, and the socket has a bottom plate 111 , a top plate 112 opposite to the bottom plate 111 , and two side plates 113 respectively connecting the bottom plate 111 and the two sides of the top plate 112 . The bottom plate 111 , the top plate 112 and the two side plates 113 enclose an accommodating cavity (not labeled in the figure), which is used for accommodating the socket body 12 . A slot 114 is formed on both sides of the rear end of the bottom plate 111 , and an opening 115 is formed on both sides of the front end of the bottom plate 111 adjacent to the side plates 113 . A rear end of the top board 112 defines a plurality of slots 116 side by side, and two sides of the rear end of the top board 112 are respectively bent downwards to extend a positioning block 117 . A substantially L-shaped elastic arm 118 extending to the side plate 113 is punched out in the middle of the top plate 112 adjacent to the left and right openings 115 of the bottom plate 111 . The elastic arm 118 has a connecting arm 1181 and a fastening portion 1182 formed by bending and extending backward from the end of the connecting arm 1181. The connecting arm 1181 extends to the top of the socket housing 11 to strengthen the connection arm 1181. The force arm structure, the end of the fastening portion 1182 is formed with a protruding portion 1183 bent inward. A foot 119 protrudes downward from the edge of the opening 115 on the side plate 113 , and the foot 119 is used to hold the socket connector 1 of the present invention on a circuit board (not shown in the figure).

3 and 4, the socket body 12 has a substantially rectangular base 121, the base 121 has a front wall 120, a rear wall 125 opposite to the front wall 120 and connects the front wall 120 and the rear wall A bottom wall 123 and a top wall 124 of 125. An insertion portion 122 protrudes forward from the front wall 120 of the base 121 . A slot 1231 is defined in the middle of the bottom wall 123 , and a slot 1232 communicating with the slot 1231 is defined at the junction of the bottom wall 123 and the front wall 120 , so that a ladder portion 1233 is formed on both sides of the slot 1231 . The top wall 124 protrudes from the top wall 124 to protrude from the same number of protrusions 127 as the slots 116 . The rear wall 125 defines a terminal groove 128 extending through the base 121 and extending to the front end of the insertion portion 122 . Two ends of the rear wall 125 respectively define a groove 129 extending to the top wall 124 .

The socket terminal 13 has a holding portion 131 , one end of the holding portion 131 is vertically bent to extend a solder tail portion 132 , and the other end of the holding portion 131 is vertically bent to extend a contact portion 133 . The contact portion 133 of the socket terminal 13 is accommodated in the terminal slot 128 , and the holding portion 131 and the solder tail portion 132 protrude from the base 121 .
