Description

A wire straight connection structure

technical field

The utility model relates to the technical field of wire connection, in particular to a wire linear connection structure.

Background technique

In normal direct wire connection, crimp terminal connection or soldering (lap welding) connection is often used.

For crimping terminal connections: matching terminals and professional crimping tools are required, and crimping is a special operation process that requires operators with professional skills and qualifications to operate. At the same time, crimping tools also need to verify the effectiveness of crimping before use. Therefore, the crimp terminal connection requires more implementation conditions for operation.

For welding (lap welding) connection: power supply is needed to make the electric soldering iron reach the expected welding temperature before welding can be carried out, and the temperature of the electric soldering iron for welding is relatively high. If the operation is a little careless, it is easy to burn other wire insulation skins, resulting in The insulation performance is reduced. At the same time, solder wire is used for welding, and the core hole of the solder wire generally contains flux. Corrosion slowly forms on the solder joint (or wire) over time, so the electrical performance of the solder connection is not easy to guarantee.

To sum up, how to solve the problems that there are many operating conditions and the electrical performance is difficult to guarantee in the straight line connection of wires has become a technical problem urgently to be solved by those skilled in the art.
