Embodiment
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
Board to board connector described in the present embodiment, as shown in Figure 1, comprise housing 1, splicing ear 2, described housing 1 is provided with the socket 11 of flat, the inwall of described socket 11 is provided with caulking groove 13, caulking groove 13 through go out housing 1, described splicing ear 2 inserts in socket 11 by caulking groove 13, described splicing ear 2 comprises pin part 21 outside as housing 1, be connected fixed part 22 for inserting in caulking groove 13 with pin part 21, and being returned the contact site 23 formed to inflection by fixed part 22, described contact site 23 extends in socket 11.
Effect of the present utility model is, it can be directly used in grafting wiring board and connect, and it includes the socket 11 of a flat, and socket 11 is highly preferably 1-3mm, comprises two end values, to meet the demand of existing most pcb board thickness.Only need when pcb board customized, on pcb board, a reserved lug measure-alike with socket 11, lug arranges pad, by pad by connection to each bar circuit of wiring board.The socket 11 of the utility model flat can effectively be fixed when being inserted in socket 11 by wiring board lug, the height of socket 11 be set to identical with wiring board thickness or slightly larger than.Wherein the electrical connection of this board to board connector is consisted of splicing ear 2, splicing ear 2 comprises pin part 21, fixed part 22 and contact site 23, pin part 21 is used for being welded in wherein one piece of wiring board as the outside of housing 1, fixed part 22 inserts the effect played in caulking groove 13 and be fixedly connected with terminal 2, contact site 23 to be returned to inflection by the fixed part 22 inserted in caulking groove 13 and forms, and makes contact site 23 form elastic bumps 14 structure for pad of conflicting.The rectangular shape of structural entity of caulking groove 13, one end is run through housing 1 and is inserted for splicing ear 2, and the side in its relative socket 11 is opening, and contact site 23 can be extended in socket 11.Production due to existing line plate all needs customization, only need increase by an above-mentioned lug in customization procedure, increase cost hardly, again by adopting the direct grafting lug of board to board connector described in the utility model to connect, abandon the mode that traditional needs two connectors are connected, the connection of convenient two pieces of wiring boards, and greatly reduce cost.
