Embodiment
Electric connector of the present utility model include socket and with it with the use of plug.As shown in Figure 1, socket includes Socket casing 1, socket insulated mounting plate 5, socket contact 3, socket base 4 and clamp nut 6.
The integrated cyclic convex edge 2 with Socket casing 1 is had in the inserted terminal arranged outside of Socket casing 1, some hub boss 7 are provided with inside the inserted terminal of Socket casing 1, this hub boss 7 is circular cone shape, also can be set to the shape that other is beneficial to interference fit grafting as required.Or as required hub boss 7 can be arranged on the inserted terminal of socket base 4.Hub boss 7 is provided with central through hole 8, and socket contact 3, through socket insulated mounting plate 5 and socket base 4, inserts in hub boss 7 by central through hole 8, forms the contact jaw of socket contact 3 in the central through hole 8 of hub boss 7.Be filled with sealant at the welding ends of socket contact 3, according to the welding ends position by colloid embedding socket contact 3, sealant can be formed, produce high pressure interpolar discharge to prevent socket contact 3 at bonding wire end.
Socket casing 1, hub boss 7 and socket insulated mounting plate 5 are formed in one structure, socket base 4 is arranged in the cavity of Socket casing 1 and socket insulated mounting plate 5 formation, and and cavity interference fit between Socket casing 1 and socket insulated mounting plate 5, namely between socket base 4 force fit Socket casing 1 and socket insulated mounting plate 5, use the fastening socket insulated mounting plate 5 of clamp nut 6 again, block air gap, achieve Socket casing 1, sealing between socket insulated mounting plate 5 and socket base 4 like this.
As shown in Figure 2, plug includes plug casing 9, plug insulated mounting plate 12, Plug contact 11, Plug base 17, attachment cap 10, lining 14, wire-fixing jacket 13 and clamp 16.
Wherein, plug casing 9 and plug insulated mounting plate 12 are formed in one structure, Plug base 17 is arranged in the cavity of plug casing 9 and plug insulated mounting plate 12 formation, and and gap interference fit between plug casing 9 and plug insulated mounting plate 12, by between Plug base 17 force fit plug casing 9 and plug insulated mounting plate 12, and by wire-fixing jacket 13 by lining 14 and plug insulated mounting plate 12 fastening, block air gap, realize plug casing 9, sealing between plug insulated mounting plate 12 and Plug base 17.
