Concrete execution mode

Below in conjunction with accompanying drawing the most preferred embodiment of the utility model signal connector is carried out concrete description.As shown in Figure 1, the utility model is to realize like this, a kind of signal connector, comprise plug 1 and socket 2, plug 1 is by insulator seat 11, hole insulator 12, hole contact 13, envelope curve back-up ring 14, shielding conductor ring washer 15, housing 16, straight shape pipe 17 and locking nut 18 constitute, described hole contact 13 inserts in insulator 12 location holes, envelope curve back-up ring 14 adopts two lobes to close up structure, it is enclosed within after closing up on the hole insulator 12, envelope curve back-up ring 14 and hole insulator 12 are pushed in the insulator seat 11, then shielding conductor back-up ring 15 is pressed in envelope curve back-up ring 14 on, extruding by straight shape pipe 17 is positioned at hole insulator 12 in the housing 16 firmly, holding wire tightens up straight shape pipe 17 by locking nut 18 and is fastened in the housing 16, and assembling and dismounting are all very convenient.Because shielding conductor back-up ring 15 has adopted the good copper of electric conductivity, so just can shield whole connector, prevent the electromagnetic interference of outside, referring to Fig. 2,3.

Envelope curve back-up ring 14 is working of plasticss, is divided into two lobes, is connected by thin slice in the middle of it, and the both sides of opening and closing place are provided with dop 141 and deck 142, and folding is all very convenient, does not need other instrument, referring to Fig. 4.

Socket 2 is made of pin insulator 21, needle contact piece 22, flange housing 23 and pin insulator back-up ring 24, described needle contact piece 22 inserts in the location hole of insulator 21, then pin insulator 22 is pushed in the flange housing 23, the madial wall of flange housing 23 is provided with groove 231, pin insulator back-up ring 24 upper side edges are provided with an outward flange 241, this outward flange 241 blocks with groove 231 and cooperates, and pin insulator 21 is fixed in the flange housing 23 by pin insulator back-up ring 24, referring to Fig. 5,6,7.
