Abstract

The utility model relates to a conducting wire connecting device which comprises compression screws 1 and a wiring slot 2, and a U-shaped metal pad 3 is buckled at one side of the wiring slot with the screw. One side of the U-shaped metal pad is provided with openings corresponding to the screw holes on the wiring slot, and the compression screws can press wires 5 via the U-shaped metal pad. The utility model has the advantage of simple structure, owing to the pad contacting with the wire, the compression screws are avoided directly contacting with the wires, the utility model reduces the damage rate of the wires and can be suitable for the occasions of frequent installation, debugging, calibration and maintenance of products.

Description

The lead termination

The utility model belongs to dynamo-electric termination, specifically a kind of lead termination.

Present electric product or other power consumption equipments such as electric energy meter, used termination generally is the termination of directly pressing lead with line pressing bolt, this termination is in the process of the installation of equipment, debugging, calibration, maintenance, since screw frequently to lead directly extruding can cause the damage of conductive line surfaces, serious when big electric current by wiring point time heating, faults such as causing the interface loose contact, strike sparks, lead is oxidized.

The purpose of this utility model provides a kind of housing screw frequent operation also to the undamaged lead termination of lead.

The purpose of this utility model can realize by following scheme, it comprises housing screw, connecting groove, at a side button one U-shaped metallic gasket of wiring troughed belt screw, a side of this U-shaped metallic gasket and the screw corresponding position perforate on the connecting groove, housing screw compresses lead by the U-shaped metallic gasket.

The utility model compared with prior art has following advantage: 1, owing to be to contact with lead by pad, strengthened the lifting surface area of lead, weaken stressed Strong degree, avoided housing screw to contact with the direct of lead, reduce the loss percentage of lead, can adapt to the occasion that product is frequently installed, debugs, calibrates, safeguarded; 2,, reduced fault because of striking sparks appears in loose contact and lead is oxidized because contacting between pad and the lead is good.

Fig. 1 is the scheme of installation of existing skill wood;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a scheme of installation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to Fig. 2, metallic gasket 3 buckles into a side of connecting groove 2 band screws, housing screw 1 is screwed in the screw sub-fraction, do not compress metallic gasket 3, make the opening part of connecting groove 2 expose incoming line 4, lead 5 inserts connecting grooves 2 and places the below of metallic gasket 3 from incoming line 4, screw housing screw 1 again, make comprehensive engagement between metallic gasket 3 and the lead 5, realize that housing screw 1, metallic gasket 3 leads 5 link together securely in connecting groove 2 places, referring to Fig. 3.When the user need unload line, unclamp housing screw 1, just can from connecting groove 2, take out lead 5.

Claims (1)

1, a kind of lead termination, it comprises housing screw (1), connecting groove (2), it is characterized in that: at a side button one U-shaped metallic gasket (3) of described connecting groove (2) band screw, screw corresponding position perforate on one side of this U-shaped metallic gasket (3) and the connecting groove (2), housing screw (1) compresses lead (5) by U-shaped metallic gasket (3).
