Description

Fast cable joint

Technical field

The present invention relates to electrical component field, and in particular to a kind of structure of cable connecting terminal.

Background technology

In the market discloses a kind of cable connecting terminal, is commonly called as " copper lug ", and it is the cable core after cable exposure In the copper tube for inserting copper lug, copper pipe extruding is packed tightly with crimper, this to pack tightly connection method, tensile strength is not high and exists Hidden danger, copper tube and cable core, chronically expanded by heating shrinkage cause copper pipe and cable core to deform, produce gap, can burn with anger, Catch fire, open circuit, production, life, the safety of property in serious harm, and this connected mode step is complicated, and installation effectiveness is low, no It is adapted to work high above the ground.

Therefore, in the market also discloses a kind of cable connecting terminal, for cable to be conductively connected with external equipment, have The screw that current supply cable conductive core is screwed in, forms the outer spiral shell being adapted with screw in the outer surface of cable conduction core in advance when using Line, and make screw and conductive core deformation locked by specific purpose tool extruding after cable conduction core screws in screw；This terminals It need to produce deformation when son is due to using and fix, be unfavorable for the reuse of binding post, and instrument crimp power is limited, and The more closely knit connection of conductive core and cable connecting terminal can not be realized；Structure similar to this cable connecting terminal also has very It is many；And due to installing the cable termination period of the day from 11 p.m. to 1 a.m, step is relative complex, adds the set-up time, reduces installation effectiveness；There is mirror In this, it is necessary to innovated on this basis.

The content of the invention

The present invention is intended to provide one kind is easy for installation, quick, can significantly improve cable connecting terminal and cable bare wire head i.e. Cable core connects the fast cable joint of density.

To achieve the above object, the technical solution adopted by the present invention is such：

A kind of fast cable joint is provided, including body, the body portion are provided with cable pawl, set on the cable pawl It is equipped with cable fixing hole, it is characterised in that：The cable pawl junction is provided with screw terminal, the body in the middle part of the body Rear portion is relatively set with the tapered dimple progressively narrowed along rear portion in an outer surface and an outer surface with the screw terminal junction Also it is tapered along rear portion progressively narrowed recessed lid, the recessed lid and the dimple or the recessed lid and the dimple and the screw Head collectively forms the shape chamber of an accommodating cable bare wire head, and the recessed lid splits groove being provided with one between the dimple, the recessed lid with Profile after the dimple combination is adapted with the profile of the screw terminal；One hollow swivel nut is set again, and swivel nut front portion is provided with The screw thread coordinated with the screw terminal, swivel nut rear portion is provided with a coniform ring cavity；During installation, cable bare wire head is inserted hollow In the coniform ring cavity of swivel nut, and overhead is in the shape chamber, then swivel nut is inserted in forward into the screw terminal and screwed, described In the presence of coniform ring cavity, it is described split groove progressively tighten up and progressively it is closely knit compression cable bare wire head.

It is preferred that, the screw terminal is rounded or symmetrical discount vibram outlet shape.

It is preferred that, dimple shape chamber surface corresponding with recessed lid shaping relatively is provided with tooth ripple；During installation, Swivel nut is screwed so that tooth ripple is inserted into cable bare wire head, to further enhance the present invention and the knot of cable bare wire head With joint efforts.

It is preferred that, swivel nut outer surface front portion is provided with nut head, is easy to screw swivel nut with instrument, in swivel nut outer surface Portion is in cylinder, and swivel nut outer surface rear portion is in truncated cone-shaped.

The present invention through arrangement above, it is quick and easy for installation, enhance what fast cable joint was combined with cable bare wire head Density, adhesion is greatly improved, and can repeatedly be utilized, and is reduced and is wasted.
