Description

Clamp for connecting cables

Technical field

The utility model provides a kind of Clamp for connecting cables, and it is to be used for cable is connected usefulness with busbar Clamp for connecting cables.

Background technology

See also Fig. 1, it is existing cable is connected the pressure copper lug of usefulness with busbar schematic diagram, on forceful electric power, be used for cable at present and the busbar ways of connecting is, the insulating barrier 2 of cable 1 is removed, expose cable core 3, one presses copper lug 4, the one end is the sleeve pipe 5 of hollow, the other end is a flat nose 6, is drilled with a circular hole on pug nose 6, and cable core 3 ends of removing insulating barrier 2 are inserted in the hollow sleeve 5 of pressing copper lug 4, and itself and cable 1 compressed realize being fastenedly connected, to press copper lug 4 to be connected with bolt 7 again with busbar 8, thus being connected of realization cable 1 and busbar 8, and the shortcoming of this connected mode is:

1, installation procedure is loaded down with trivial details, inefficiency;

2,,, and cause the virtual connection of cable 1 and busbar 8 so cable 1 becomes flexible easily with pressing between the copper lug 4 in use for some time because of cable is to compress with the hollow sleeve 5 of pressing copper lug 4 to be connected;

3, cost height, generally pressing copper lug 4 all is disposable use, and causes the waste of copper product.

The utility model content

The purpose of this utility model is, a kind of connection folder is provided, its have install easily, cable and busbar good connecting effect and the low advantage of cost.

A kind of Clamp for connecting cables of the utility model is characterized in that, comprising:

One underframe, this underframe is that a lamellar body bends and forms, general like a shape, the both sides of this underframe are identical, and all form hook portion in the end of both sides, form recess on the root of these both sides, the shape of this recess is similar to the ear of upper frame and greater than the ear of upper frame, and the ear of this upper frame is contained in the recess of underframe, and there is a screw centre of the bottom of this underframe, and underframe both sides inner face has a circular hole respectively;

Two back-moving springs, an end of this two back-moving spring are connected with the circular hole of upper frame both sides inner face respectively, and the other end is connected with the circular hole of underframe both sides inner face;

One bolt, the screw of this bolt and underframe bottom is spirally connected.

Wherein the edge of this upper and lower base of frame is formed with shank on the other hand.

Wherein the inboard of the hook portion of this upper and lower frame ends is formed with anti-skidding serrations.

Wherein the inboard of the screw of this underframe bottom is connected with an edge cover, and there is a screw centre of edge cover.

Wherein the end of this bolt is articulated with a crimping piece.
