The outwall of one end of the conductive contact near to the handle is spliced into the inner hole of the handle and equipped with a leaf spring, wherein the leaf spring comprises a base plate fixed on the outwall of the conductive contact and an unwarping part formed by bending one end of the base plate backwards and extending and a bending structure is formed in the middle of the unwarping part and the free end of the unwarping part is the projection end projecting outwards; a notch mated with the bending structure of the leaf spring and a detachable through hole allowing for being built into by the projection end of the leaf spring are set on the handle inner hole wall of the end mated with the conductive contact and the detachable through hole communicates the inner and outer of the handle wall. The connection structure effectively locks the circumferential stopping function between the conductive contact and the handle, ensures the reliable connection between the conductive contact and the handle, makes the assembly and disassembly more convenient.

Description

The conductive contact of plug for industrial use and the syndeton of handle

Technical field

The present invention relates to a kind of plug for industrial use (also claiming coupler), particularly the syndeton of a kind of conductive contact of plug for industrial use and handle.

Technical background

The patent No. is that 200480013760.0 Chinese patent application discloses a kind of electrical connecting member, comprise the conductive contact and the handle that removably connect by jockey, jockey comprises near the near-end of conductive contact and conductive contact makes whole elastic component, and having an outwards outstanding end, outwards outstanding end can flexibly embed near the through hole that is bonded on the near-end that is formed on handle.Circumferential stop between above-mentioned conductive contact and the handle and dismounting all embed in the through hole that is engaged in the handle close end by the outwards outstanding end of elastic component and realize, in the process that conductive contact and handle are dismantled, the outwards outstanding end of elastic component is subjected to may taking place after the repeatedly effect of extracting tool impaired, and after the outwards outstanding end of elastic component is impaired, can not play circumferential stopping function to conductive contact and handle, can not guarantee reliable connection the between conductive contact and the handle.

Summary of the invention

The object of the invention is to provide a kind of and can effectively plays the circumferential stopping function between conductive contact and the handle, guarantee reliably to connect between conductive contact and the handle, assembling and dismounting be the syndeton of the conductive contact of plug for industrial use and handle comparatively easily all, having solved conductive contact that prior art exists and circumferential stop between the handle and dismounting all embeds in the through hole that is engaged in the handle close end by the outwards outstanding end of elastic component and realizes, in the process that conductive contact and handle are dismantled, the outwards outstanding end of elastic component is subjected to may taking place after the repeatedly effect of extracting tool impaired, and after the outwards outstanding end of elastic component is impaired, can not play circumferential stopping function to conductive contact and handle, can not guarantee problems such as reliable between conductive contact and the handle is connected.

Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: it comprises conductive contact and handle, the end outer wall that described conductive contact and handle are close is pegged graft and is engaged in the endoporus of handle, this end outer wall that conductive contact and handle are close is provided with leaf spring, described leaf spring comprises and is used for back bending the warping part that extends to form with the fixing base portion of conductive contact outer wall with by base portion one end, the middle part of described warping part is formed with a bending structure, and the free end of warping part forms cambered outwards protruding end; Be formed with the dismounting through hole that draw-in groove that cooperates with the bending structure of leaf spring and the protruding end that allows leaf spring embed on described handle and this end inner hole wall that conductive contact matches, described dismounting through hole be communicated with handle wall portion inside and outside.During dismounting, only need to adopt and have the in-line end and act on the warping part and promote certain angle near near the direction of the cambered outwards protruding end of free end the free end of warping part radially inwardly being pressed and along the circumferential direction extend to the warping part, make between the draw-in groove of the bending structure of warping part and handle inner hole wall and throw off, conductive contact and handle can be separated; Also can adopt the bottle opener of in-line to be inserted into inwardly to apply certain active force in the dismounting through hole and turn an angle, also can throw off the dismounting between realization conductive contact and the handle between the draw-in groove with the bending structure of warping part and handle inner hole wall.Because when dismounting, extracting tool does not act directly on the bending structure of warping part, so even cambered outwards protruding end is impaired in unloading process, the draw-in groove that forms on the bending structure that adopts middle part, leaf spring warping part and the handle inner hole wall cooperates, thereby can play effectively circumferentially stopping function, the reliable connection between guarantee to know clearly conductive contact and the handle to conductive contact and handle.
