Embodiment

Referring to figs. 1 through Fig. 7, a kind of fast waterproof connector, comprise male end 1 and female end 2, and the afterbody of described male end 1 and female end 2 is connected with wire 3, the end face of described male end 1 is provided with the connection-peg 10 of evagination, the conductive jack 11 that the end face setting of described connection-peg 10 is electrically connected to the wire 3 of its afterbody; The end face of described female end 2 is provided with the interface 200 of indent, be provided with the conductive pin 201 corresponding with described conductive jack 11 in described interface 200, described connection-peg 10, interface 200 are hard material and make, the madial wall of described interface 200 adopts the moulding technology integrated injection molding to form elastic water-proof circle 22, the end face of described elastic water-proof circle 22 is concordant with the end face of described interface, after pegging graft, interface is connected with connection-peg closely, can not form the hydrops cavity, the waterproof effect ideal.

The lateral wall of described connection-peg 10 can be smooth, also can be provided with some circumferential waterproof rings 101, and waterproof ring 101 is connected tightr with the madial wall of elastic water-proof circle 22, strengthens waterproof effect.

Described female end 2 comprises tail cover 20 and is arranged on the grafting cover 21 in described tail cover 20, described interface is arranged on described grafting cover 21, the cover 21 of pegging graft is provided with the through hole 213 that conductive pin 201 is installed, first make the cover 21 of pegging graft during production, then the cover of pegging graft is put into mould, on the cover 21 of pegging graft, injection moulding forms elastic water-proof circle 22, then will fill in the through hole 213 on the cover 21 of pegging graft with the conductive pin 201 of wire, then will peg graft and overlap 21, conductive pin 201 is put into mould with the assembly of elastic water-proof circle 22, injection moulding forms female end, simple in structure, convenient for production.

The madial wall of described interface is provided with some axial dovetail grooves 211, makes the lateral wall of described elastic water-proof circle 22 form dovetail section 221.At connection-peg, insert in the interface process, the inwall of elastic water-proof circle 22 is squeezed, produce flexural deformations, can make elastic water-proof circle 22 shrink to axle center, after dovetail groove 211 and dovetail section 221 are set, the outer wall of elastic water-proof circle 22 is connected tightr with the inwall of interface, can be squeezed and comes off or produce axial displacement.
