Description

A special copper-aluminum nose for low-voltage cable branch box

technical field

The utility model relates to the technical field of cable connection, in particular to a special copper-aluminum nose for a low-voltage cable branch box.

Background technique

The copper nose is a connecting piece that connects and protects the copper wire and the required connection items. It is a connector used for connecting wires and cables to electrical equipment. The top side is the edge for fixing the upper screw, and the end is the copper core of the wire and cable after the upper stripping. Copper lugs are often used for cable end connection and continuation, which can make the connection between cables and electrical appliances stronger and safer. It is a commonly used material for construction, power equipment and electrical connections. Generally, when a wire is connected to a terminal, if it is a single-strand wire of 10 square millimeters or less, it needs to bend a circle at the end of the wire to connect to the terminal. However, if it is a multi-strand copper wire of more than 10 square millimeters, it needs to be installed with a terminal lug, and then connected to the terminal. The copper and aluminum lugs produced by all manufacturers on the market are basically the same as the diameter of the screw hole and the diameter of the cable. The hole diameter on the copper bar of the 400v low-voltage cable distribution box is generally 10.5, which is equivalent to a 50 square meter cable. The actual cable diameter may only be 16 or 25 square meters, but the copper nose produced by the manufacturer has a screw hole diameter similar to the cable diameter. As a result, a section of the cable in the distribution box cannot be crimped to the copper nose. How to invent a special nose suitable for the low-voltage cable distribution box is a problem to be solved urgently by those skilled in the art.

Utility model content

The purpose of this utility model is to provide a special copper-aluminum nose for the low-voltage cable branch box to solve the problem that the copper nose produced by the traditional manufacturer proposed in the background technology is that the diameter of the screw hole is similar to the diameter of the cable, resulting in a section of cable in the low-voltage branch box. The problem that the wire cannot be crimped to the copper nose.

In order to achieve the above purpose, the utility model provides the following technical solutions: a special copper-aluminum nose for the low-voltage cable branch box, including a fixed end, the outer wall of the fixed end is provided with a screw fixing hole, and the left end of the fixed end is fixed A cable connection end is connected, and a cable installation groove is opened on the left side wall of the cable connection end.

Preferably, the diameter of the screw fixing hole is 10.5mm.

Preferably, the circumference diameter of the cable connection end is ten or twelve millimeters.

Preferably, the circumference diameter of the cable installation groove is 5.5 or 7 mm.

Preferably, the fixed end is made of copper, and the cable connection end is made of aluminum.

Compared with the prior art, the beneficial effect of the utility model is that the special copper-aluminum nose for the low-voltage cable branch box has a reasonable design and strong practicability. The diameter of the screw fixing hole is set to 10.5 mm, and the diameter of the cable installation groove is set to 5.5 or 7 mm, the outer diameter of the cable connection end is kept at 10 or 12 mm, which can completely crimp a section of cable in the distribution box to the copper lug, and solve the problem that the 16 or 25 square meters of cables entering the distribution box cannot be crimped copper and aluminum Nose problems.
