Abstract

The present invention relates to an external push-pull expansion type connector in the technical field of electrically connected devices, which comprises an insulator 1 and an insulator 2, wherein an inserting rod and an inserting needle are arranged in the insulator 1 and the insulator 2 respectively and the insulator 1 and the insulator 2 are fixed in a connecting seat and a sleeve pipe respectively. The head end of the sleeve pipe is provided with at least three axial openings and the edge of the head end of the sleeve pipe is provided with an arc inner protrusion. The outside of the connecting seat is provided with a circumferential groove and the outer surface of the connecting seat is axially provided with a positioning groove. The root part of the axial openings is provided with a lug boss and both sides of the lug boss are provided with a returning spring respectively. The outside of the sleeve pipe is sheathed with a moving sleeve and the other ends of the two returning springs are axially and oppositely fixed with the moving sleeve. A clamping nail is arranged in the moving sleeve and is matched to be inserted in the positioning groove. When the inner protrusion is clamped in the circumferential groove, the inserting needle is just inserted into an inserting hole of a corresponding inserting rod correspondingly and at the same time, one end of the moving sleeve presses against the outer side of the head end of the sleeve pipe. The connector has the advantages of self locking, reliable use, interchange use of the insulator 1 and the insulator 2 and convenient welding and can be used for various quickly disassembled and assembled electrically connected places and equipment.

Description

A kind of push-pull expansion type connector

Technical field

The present invention relates to a kind of arrangements of electric connection, particularly a kind of connector.

Background technology

In the prior art, a kind of connector is arranged, locking mode is an in-ward hook, mainly include insulator one and insulator two, be provided with at least one inserted link that has jack in the insulator one, the tail end of inserted link stretches out outside the insulator one, is provided with in the insulator two and inserted link contact pin one to one, and stretch out outside the insulator two at the two ends of contact pin; Described insulator one is fixed in the Connection Block, and insulator two is fixed in the sleeve pipe, is provided with the buckle and the draw-in groove that cooperatively interact between sleeve pipe and the Connection Block, when buckle snaps in draw-in groove, in the corresponding jack that inserts on each inserted link of contact pin.The tail end of inserted link and contact pin is used for welding lead, and the flange end of Connection Block can be fixed on device one fixedly on plate or the wall; When it used, relative the pegging graft of head end with Connection Block and sleeve pipe can plug contact pin and inserted link fast, also can separate fast; Its weak point is: after the clamping, withdrawing power is big mutually for buckle and draw-in groove; The structural requirement buckle of buckle and draw-in groove caves inward, and causes insulator one different with insulator two structures, and both can not exchange; In addition, in the contact pin welding lead, insulator need be pulled down welding, its inconvenient operation.

Summary of the invention

The purpose of this invention is to provide that a kind of dismounting and convenient welding, use are reliable, insulator one and insulator two interchangeable push-pull expansion type connectors.

The object of the present invention is achieved like this: a kind of push-pull expansion type connector, comprise insulator one and insulator two, be provided with at least one inserted link that has jack in the insulator one, the tail end of inserted link stretches out outside the insulator one, be provided with in the insulator two and inserted link contact pin one to one, stretch out outside the insulator two at the two ends of contact pin; Described insulator one is fixed in the Connection Block, and insulator two is fixed in the sleeve pipe, and described sleeve pipe head end is provided with at least three road axially opens, and described axially open evenly distributes in a circumferential direction; The head end edge of sleeve pipe is provided with the internal projection of arc, Connection Block is provided with a circumferential slot outward, the Connection Block outer surface is axially arranged with location notch, location notch extends to the other end from Connection Block axle head end, the root that is positioned at axially open on the described sleeve pipe is provided with the radially boss of evagination, the boss both sides respectively are provided with a back-moving spring, sleeve pipe is set with outward and moves cover, the other end of two back-moving springs respectively with move the axial relative fixed of cover, move in the cover and be provided with radially inwardly protruded bail, described bail passes described axially open and cooperates in the insertion location notch; When the internal projection axial motion and when snapping in circumferential slot, in the jack on the corresponding just corresponding inserted link of pegging graft of contact pin, simultaneously, move inboard conflict the in edge of cover head end in the sleeve pipe head end outside.

The tail end of each inserted link and contact pin is used for welding mutually with lead, during this device work, mobile cover can be under external force to the head of sleeve pipe, the tail end direction moves, after external force is removed, move and be enclosed within the action of reset spring, can return to initial condition, its meaning is: external force is pushed mobile cover and is moved to the tail end direction of sleeve pipe, mobile cover also can be separated with the sleeve pipe head end outside, under external force continuation effect, sleeve pipe head end strain breaks away from circumferential slot, the setting of axially open, make that the sleeve pipe head end can strain, can contact pin and inserted link be separated along the location notch direction after the sleeve pipe strain; When needs are pegged graft inserted link and contact pin mutually, at first will move cover and push head end direction to sleeve pipe, again with bail and location notch over against pegging graft, make the corresponding one by one grafting of contact pin and inserted link, after grafting puts in place, internal projection snaps in the circumferential slot once more, at this moment, and removal external force, moving cover moves, the edge of its head end is inboard conflicts in the sleeve pipe head end outside, plays locking action, and external force can't be separated contact pin and inserted link by pulling lead or sleeve pipe.Compared with prior art, this device is pegged graft and convenient separation, can self-locking, use reliably, and insulator one and insulator two can exchange use, have reduced production cost, have enlarged the scope of application.This device can be used for being used for power supply, signal transmission etc. on the electrical connection place or equipment of various fast assembling-disassemblings.

For making things convenient for welding operation, the tail end tail pipe that has been threaded is taken in the adapter that has been threaded of sleeve pipe tail end, is provided with wire clamp in the tail pipe, wire clamp one end with take over relative fixed, the guiding conical surface through cooperatively interacting between the wire clamp other end and the tail pipe is connected.In when welding, as long as after tail pipe unclamped, unload lower linking tube, can expose the tail end of contact pin, can directly weld, easy to operate.
