Description

a wiring clip

technical field

The utility model relates to a connection clamp for a secondary terminal of a power distribution transformer, in particular to a connection clamp with an external connection board.

Background technique

The secondary outlet of a 10kV distribution transformer is usually crimped to the secondary terminal of the transformer with equipment clamps. Since there is a certain gap between the crimping of ordinary clamps and the secondary terminal of the transformer, it can only rely on the upper and lower nuts and clamps of the equipment clamp. The connection conducts electricity. Due to the small contact surface between the wire clip and the secondary terminal of the transformer, it is very easy to cause heat at the connection between the terminal post of the distribution transformer and the wire clip when the transformer is under heavy load, causing the rubber beads on the secondary side of the transformer to age and harden, resulting in oil leakage from the transformer .

Utility model content

The technical problem to be solved by the utility model is to provide a terminal clip which enlarges the electrical connection contact surface, improves the conductivity, and avoids overheating under heavy load.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a terminal clamp, which is characterized in that it includes a terminal, a sleeve and a horizontal terminal plate; the terminal is connected to the distribution transformer, and the sleeve The sleeve is screwed on the terminal through its internal thread, and the waist of the sleeve is provided with a conjoined horizontal terminal board, and the right end of the horizontal terminal board is connected with the external wire through bolts and nuts.

A further improvement of the utility model is that: the right end of the horizontal wiring board is connected to the external wiring through a bolt provided with a pressure plate nut.

Symmetrical planes are provided on the outer peripheries of both ends of the sleeve.

The beneficial effects produced by adopting the above-mentioned technical solution are: the utility model has simple structure and high reliability, and can be widely applied to 10kV distribution transformers, increases the contact surface between the distribution transformer terminal and the secondary outgoing line, and effectively solves the problem of traditional The overheating problem at the connection between the terminal post of the distribution transformer and the secondary outgoing line caused by the connection technology improves the conductivity, avoids the oil leakage fault of the transformer, and improves the reliability of power supply.
