CN2612089Y - Cable and wire terminal with self-lock up - Google Patents

Abstract

A self-lock cable connector can resolve the problems of prior art which connector used on electric appliance uses muffle structure, needing special tool to press and connect in connection, and contactor of wire connector has point contact with low current rating to cause overload accident. The utility model comprises a connector, characterized in that one connecting end of the connector is open and inserted into a connecting hole of a hollow lock nut, arranged with a screw through hole vertically to the connecting hole, while the connecting hole is screwed with an internal lock rod.

Description

The self-locking cable terminal

Technical field

The utility model belongs to the binding post that uses on a kind of electric power facility, particularly a kind of self-locking cable terminal.

Background technology

At present, the binding post that uses on the electric power facility such as ammeter box, power distribution cabinet, mostly be sleeve type structure, during connection lead inserted sleeve pipe, carry out crimping with the specific purpose tool Press Plier, because the terminal contact after the crimping is the some contact, ampacity is little, is everlasting the overload fault takes place herein, very causes accidents caused, simultaneously when construction, special-purpose Press Plier must be arranged, and the binding post of this structure to expend the copper material more.

The utility model content

The purpose of this utility model provides a kind of self-locking cable terminal, can construct without specific purpose tool, and easy to operate, contact resistance is little, increases ampacity, connects reliably, and saves non-ferrous metal.

The purpose of this utility model is achieved by the following technical solution: it comprises binding post, it is characterized in that: terminals of binding post are the opening terminal, the opening terminal is inserted in the connecting hole of hollow locknut, and the direction perpendicular with connecting hole has tapped through hole, is screwed locking bar in the hole.

Assemble slidably lock dog in the inboard of above-mentioned locking bar.

During construction, the termination of lead is inserted in the opening terminal, turn locking bar with instrument then, the top power of locking bar makes opening shape binding post inwardly closed, and the lead termination is firmly locked.

The utility model has the advantages that: can construct without specific purpose tool, easy to operate, contact resistance is little, increases ampacity, connects reliably, and saves non-ferrous metal.

Embodiment

See Fig. 1-3, concrete structure is as follows: terminals of binding post constitute opening terminal 4 by upper and lower two arcs, opening terminal 4 is inserted in the connecting hole of hollow locknut 2, the direction perpendicular with connecting hole has tapped through hole, be screwed locking bar 1 in the hole, assemble slidably lock dog 3 in the inboard of locking bar 1.Locking bar 1 can adopt hexagon socket head cap screw, also can adopt the outer-hexagonal bolt.

Claims (2)

1, a kind of self-locking cable terminal, it comprises binding post, it is characterized in that: terminals of binding post are the opening terminal, and the opening terminal is inserted in the connecting hole of hollow locknut, and the direction perpendicular with connecting hole has tapped through hole, is screwed locking bar in the hole.

2, self-locking cable terminal according to claim 1 is characterized in that: assemble slidably lock dog in the inboard of locking bar.
