Abstract

The utility model provides an electric connector connected to a circuit board, comprising an isolation body and a plurality of conductive terminals held inside the isolation body. Wherein, the terminal is provided with a holding part, a contact part vertically extending from one end of the holding part, and a welding part connected by the other end of the holding part correspondingly; the welding part is used for welding on the circuit board. In order to prevent the welding point of the terminal and the circuit board from cracking, the terminal is also provided with an elastic part used for elastically connecting the welding part to the holding part. The elastic part can generate elastic deformation and absorb the limited displacement generated by the electric connector corresponding to the circuit board to reduce the acting force between the welding part and the circuit board and the possibility that the welding point generates cracking.

[embodiment]

See also Fig. 2, electric connector 200 of the present utility model is in order to being installed on the circuit board (not shown), and connects with another connector (not shown).This electric connector 200 comprises insulating body 20, several conducting terminals 40 and is coated on the metal shell 50 of insulating body 20 peripheries.

Please in conjunction with consulting Fig. 2～4, insulating body 20 is rectangular-shaped, its be provided with installed surface 21 towards circuit board, vertical with installed surface 21 in order to the interface 23 that connects with aforementioned another connector and with interface 23 opposing to breech face 24.Insulating body 20 is in being provided with the holding slot 202 that is parallel to installed surface 21 near installed surface 21, and this holding slot 202 connects the interface 23 and breech face 24 of insulating body 20.Being connected in holding slot 202 downsides is provided with groove 204 towards installed surface 21, and the width of groove 204 is narrow than holding slot 202.Being connected in the upside of holding slot 202 is provided with equally the accepting groove 206 narrow than holding hole 202, and this accepting groove 206 connects to interface 23, and is being provided with retaining wall 25 near breech face 24 places.The top of corresponding accepting groove 206 is provided with the identical blind hole 208 of width and holding slot 202, and this blind hole 208 is offered from interface 23, and is provided with link slot 209 between blind hole 208 and accepting groove 206.

Terminal 40 is a sheet metal stamping-out molded article, it is provided with flat first holding parts 41, at first holding parts, 41 1 end vertical extent tabular contact site 42 is arranged, vertically be connected with and first holding parts, the 41 parallel second relative holding parts 43 in contact site 42 extending ends.The other end of first holding parts 41 extends outstanding " several " shape elastic portion 44 in oriented contact site 42 the same sides, and elastic portion 44 is connected with first holding parts 41 and has conplane limiting section 45, tail end by limiting section 45 is extended with weld part 46, this weld part 46 is in the opposite side of elastic portion 44 relative first holding parts, 41 directions, and parallel with first holding parts 41, this weld part 46 in order to surface soldered in the aforementioned circuit plate.Terminal 40 inserts in the insulating body 20 from the interface 23 of the body 20 that insulate, wherein first holding parts 41 inserts holding slot 202 with limiting section 45, second holding parts 43 inserts blind hole 208, and first holding parts 41 and holding slot 202 interference engagement, and limiting section 45 slidably cooperates with holding slot 202, and second holding parts 43 is in blind hole 208 interference engagement.Contact site 42 is contained in link slot 209, and relative first holding parts 41 of the width of elastic portion 44 and weld part 46 is narrower with limiting section 45, so elastic portion 44 can be contained in resettlement section 206, and weld part 46 can pass groove 204 and extend to and protrude from installed surface 21.
