Description

A kind of fast connection terminal for power transmission line

technical field

The utility model relates to the field of electric equipment and appliances, in particular to a quick connection terminal for electric power transmission lines.

Background technique

With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the use of terminal blocks is increasing, and there are more and more types. However, there are still many shortcomings in the terminal blocks that people use now. For example, the screw-pressed terminal blocks use flat-head bolts to screw into the terminal to compress the wires. When wiring, the bolts need to be tightened, which is troublesome. It is easy to fall off from the component, and cannot be fixed well, and the fixing effect is poor. In addition, the electric resistance of the terminal block is relatively weak, and the scope of application is relatively small.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a quick connection terminal for power transmission line with simple result, reasonable design, firm connection and convenient use.

A quick connection terminal for electric power transmission line according to the utility model includes a housing, a copper pipe, a connecting part, a cap and a sliding block, the housing is a main supporting part, and the middle part of the housing is longitudinally arranged There is a containing groove, and a copper pipe is embedded in the containing groove, and the length of the copper pipe is slightly shorter than the length of the casing; the upper end of the casing is provided with a slot, corresponding to the opening on the copper pipe The slot is provided with an opening; a hollow connecting part is provided at the upper end of the slot, and a sliding block is arranged in the connecting part, and the lower end of the sliding block extends into the opening of the copper pipe, and the sliding block is placed in the opening of the copper pipe. Slide up and down inside; the upper end of the connecting part is matched with a cap, the cap is provided with a slot, the upper end of the sliding block is connected with a push handle extending to the outer end of the slot for insulation, and its lower end is provided with a An insertion hole; a spring is arranged between the cap and the push handle. When using wiring, press the push handle down to drive the sliding block to move into the copper tube, so that the socket hole is completely exposed in the copper tube, put the connecting wire into the socket hole of the sliding block, and slide it under the action of the spring. The block moves up, compressing the wire.

Further, the length of the copper pipe is 5-8 mm shorter than that of the shell.

Further, the sliding block is made of conductive material.

Further, the connecting part is screwed to the cap, so that when the spring is damaged, the cap can be unscrewed to replace a new spring.

The beneficial effects of the utility model are: compared with the prior art, the structure is simple and reasonable, easy to use, fast wiring, high efficiency, and the wire crimping is firm, the conductivity is improved, and the device has a simple manufacturing process and low production cost. It is convenient for promotion and application.
