Embodiment
As shown in Figure 1, 2, the present invention includes contact pin 1, jack 2, contact pin upper insulator 3, contact pin lower insulator 4, jack upper insulator 5, jack lower insulator 6, metal partion (metp) 7, plug body 8, binding ring 9, jack housing 10, sealing ring 11, hood 12, holding screw 13, cable clip 14, screw 15, packing ring 16.
Contact pin 1 forms contact together with jack 2, the soldering terminals of contact pin 1 and jack 2 or crimping lead wire.
Contact pin 1 loads in the hole of contact pin upper insulator 3 and contact pin lower insulator 4, jack 2 loads in the hole of jack upper insulator 5 and jack lower insulator 6, separates between some (being generally 4) contact pins 1 or some (being generally 4) jack 2 with metal partion (metp) 7.Metal partion (metp) 7 end edge has the hole can welding earth lead.
Contact pin 1 and jack 2, with cylinder boss, match with contact pin upper insulator 3, contact pin lower insulator 4, jack upper insulator 5, jack lower insulator 6 aperture step respectively, prevent moving axially of contact pin 1 and jack 2.
Contact pin upper insulator 3, contact pin lower insulator 4, jack upper insulator 5, jack lower insulator 6 have keyway, coordinate, prevent the radial rotary of insulator with the convex key in plug body 8, jack housing 10 inner circle.
Plug body 8 and jack housing 10 adopt spline fitted, ensure that the aperture position of each insulator is relatively fixing, connecting and ensure that the insertion of corresponding contact pin 1, jack 2 in separation process and extract, contact pin upper insulator 3, contact pin lower insulator 4 can exchange with jack upper insulator 5, jack lower insulator 6, thus can change the conversion of contact pin and jack in plug, socket in plug body 8 with jack housing 10.
Hood 12 and plug body 8, jack housing 10 tail end, with being threaded, having step and contact pin lower insulator 4, jack lower insulator 6 to hold out against, prevent moving axially of insulator.
In use, holding screw 13 with unscrewing, hood 12 is backed out, contact pin 1, jack 2, contact pin upper insulator 3, contact pin lower insulator 4, jack upper insulator 5, jack lower insulator 6, metal partion (metp) 7 can take out in plug body 8 and jack housing 10, separable between contact pin upper insulator 3, contact pin lower insulator 4, separable between jack upper insulator 5, jack lower insulator 6, so that contact pin 1, jack 2 take out.
By wire through the hole in the middle of hood 12, contact pin 1 takes out from contact pin upper insulator 3 and contact pin lower insulator 4, jack 2 takes out from jack upper insulator 5, jack lower insulator 6, with the wire that is terminated, contact pin 1, jack 2 weld or are crimped onto on the cable core that strips successively, contact pin 1, jack 2 can weld with the termination form of wire, also can crimp.
Contact pin 1, the jack 2 of differential signal transmission are pair twist termination with the wiring of netting twine, and must be pair twist termination, that is: 1 and 4 termination one twisted pair wires in Fig. 2,2 and 3 termination one twisted pair wires, 5 and 8 termination one twisted pair wires, 6 and 7 termination one twisted pair wires.When contact pin 1, jack 2 are then difficult upper wiring requirement when connecing power line.The ground shield welding of wire or solderless wrapped connection are tightened on the hole of metal partion (metp) 7.
The cylindrical of contact pin lower insulator 4 and jack lower insulator 6 has the groove by wire, can conducting wire, contact pin 1 good for termination is loaded contact pin upper insulator 3 and contact pin lower insulator 4, jack 2 good for termination is loaded jack upper insulator 5, jack lower insulator 6, then by reinstalling plug body 8 and jack housing 10 shown in Fig. 1 respectively.
Hood 12 is screwed back in plug body 8 and jack housing 10, tighten holding screw 13, then tighten screw 15, compress cable clip 14, fix cable.
The plug of the good wire of termination and socket plug together and connect, can differential signal transmission and power supply signal.
The contact pin 1 of differential signal transmission and the quantity of jack 2 are generally the integral multiple of 4, and separated respectively by metal partion (metp) 7, the contact pin 1 of transmission power supply signal and the fixing restriction of the quantity of jack 2, also have the contact pin 1 of metal partion (metp) 7 and other differential signal transmission and jack 2 to separate.
