Description
[technical field]
The present invention relates to a kind of electric connector, relate in particular to a kind of electric connector with first insulating body and second insulating body.
[background technology]
See also Fig. 8 and shown in Figure 9, it has showed a kind of structure of existing electric connector.Existing electric connector 10 wherein shown in Figure 8 ' comprising: insulating body 1 ', be immobilizated in terminal 2 on the insulating body ' and be shielded in the outer shielding casing 3 of insulating body ', described insulating body 1 ' have base portion and from the docking section that base portion extends forward, front end face in the docking section be concaved with backward receiving space 11 '.Described terminal be immobilizated in insulating body 1 ' on, the one end have protrude into receiving space 11 ' contact site, the other end has and extends back the outer weld part of insulating body.
See also shown in Figure 9ly, it is the cutaway view along C-C line direction shown in Figure 8, and the internal structure of having showed insulating body.The receiving space 11 that this insulating body 1 ' be provided with is positioned at the docking section ' and communicate with receiving space and run through several accepting groove conduits 12 of insulating body base portion rearward end ', have between the accepting groove that each accepting groove is adjacent a wall portion 13 '.Because of the structural limitations of this connector, need have certain-length as the docking section of electric connector, in order to keep docking preferably with butt connector; And the base portion of the described electric connector outside needs to coat a shell, and will make shell and electric connector have fixing preferably, so described base portion also need guarantee to have enough length.Therefore, the overall dimensions c on the described electric connector fore-and-aft direction generally should not reduce, and this overall dimensions c generally is made up of receiving space size a on the fore-and-aft direction and accepting groove conduit size b.Wherein, if docking section frame mouth is not deformed, described receiving space size a is unsuitable long, because of the overall dimensions c of electric connector constant, thereby cause that accepting groove conduit size b is long, in forming process, the wall portion 13 between the described accepting groove ' very easily fracture.Conversely, if accepting groove conduit size b is shortened the wall portion fracture that prevents between the conduit, then receiving space size a can be long, thereby described docking section frame mouth easily deforms.So in forming process, reduced production efficiency.
Therefore, necessary existing electric connector is improved, to overcome defective of the prior art.
