Abstract

The invention provides a cable quick connector, which comprises a body. The front part of the body is provided with a cable claw and the middle part of the body is provided with a screw head. The connection part of the rear part of the body with the screw head is oppositely provided with a recessed base and a recessed cover. The external surface of the recessed base is conical and gradually tapered along the rear portion thereof. The external surface of the recessed cover is also conical and gradually tapered along the rear portion thereof. The recessed base and the recessed cover or the recessed cover and the recessed base form a form cavity together with the screw head and the form cavity is used for an accommodating cable bare head. A split groove is formed between the recessed cover and the recessed base. After the recessed cover and the recessed base are combined together as one piece, the profile of the combined piece is matched with the profile of the screw head. A screw sleeve is additionally arranged. The front portion of the screw sleeve is provided with threads matched with the screw head. The rear portion of the screw sleeve is provided with a conical ring cavity. During installation, the cable bare head is inserted into the conical ring cavity of the screw sleeve to abut against the interior of the form cavity. After that, the screw sleeve is pushed forwardly to be sleeved inside the screw head and screwed tightly with the screw head. Under the action of the conical ring cavity, the split groove is gradually tightened to gradually and densely press the cable bare head. The cable quick connector is convenient and quick to install. The combination compactness of the cable quick connector with the cable bare head is strengthened and the binding force between the cable quick connector and the cable bare head is greatly improved.

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 ", it be cable exposure after cable core Insert in the copper tube of copper lug, copper pipe is extruded with crimper is packed tightly, 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 the deformation of copper pipe and cable core, produce gap, can burn with anger, Catch fire, open circuit, the safety of production, life, 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, the outer spiral shell being adapted with screw in the outer surface formation of cable conduction core in advance when using Line, and being extruded by specific purpose tool after cable conduction core screws in screw makes screw locked with conductive core deformation；This terminals Need to produce deformation and fix when son is due to using, 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, increased 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, the cable pawl and are provided with Cable fixing hole, it is characterised in that：The body middle part is provided with screw terminal, the rear body with the cable pawl junction The tapered dimple progressively narrowed along rear portion in an outer surface is relatively set with the screw terminal junction and an outer surface is also in The recessed lid that taper is progressively narrowed along rear portion, the recessed lid is common with the dimple and the screw terminal with the dimple or the recessed lid With the shape chamber for constituting an accommodating cable bare wire head, one is provided between the recessed lid and the dimple and splits groove, the recessed lid with it is described Profile after 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 and institute The screw thread of screw terminal cooperation is stated, swivel nut rear portion is provided with a coniform ring cavity；During installation, cable bare wire head is inserted into hollow swivel nut Coniform ring cavity in, and overhead is in the shape chamber, then swivel nut is inserted in forward the screw terminal and is screwed, in the circular cone In the presence of shape ring cavity, it is described split groove progressively tighten up and progressively it is closely knit compression cable bare wire head.

Preferably, the screw terminal is rounded or symmetrical discount vibram outlet shape.

Preferably, dimple shaping corresponding shape chamber surface relative with the recessed lid is provided with tooth ripple；During installation, Screw swivel nut so that tooth ripple is inserted into cable bare wire head, be used to further enhance the knot of the present invention and cable bare wire head With joint efforts.

Preferably, swivel nut outer surface front portion is provided with nut head, is easy to screw swivel nut with instrument, in swivel nut outer surface In cylinder, swivel nut outer surface rear portion is in truncated cone-shaped in portion.

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