0.6, 0.8, 1.0, 1.5mm pierced terminal wires are widely used. What is a pierced terminal wire? In fact, the piercing terminal wiring harness also belongs to the category of terminal wires. The pierced terminal wiring harness has an obvious application characteristic structure.
 
 
1. Pierced terminal wire, easy to install, direct conductive connection to prevent oxidation, no false welding, to ensure a good electrical connection without damaging the wire.
2. The insulated wire can be used as a cable branch without stripping, and the connector is completely insulated. It can be tapped at any position of the cable. The installation space requirements are extremely small, saving costs.
3. The pierced terminal line can reduce production costs, improve production efficiency, unique joint design, reduce production energy consumption, realize environmentally friendly manufacturing, semi-automatic technology, and provide high reliability.

Advantages of pierced terminal wire connector: It can achieve efficient and reliable tap terminal connection, which serves as a bridge connecting various functions. Products are used in motors and motors, water pumps, air compressors, washing machines, generators, transformers, power tools, etc.


The connection between the motor lead wire and the enameled wire, and the paint on the outer layer of the enameled wire, mainly plays the role of anti-corrosion and anti-oxidation in the working environment. The enameled wire is usually depainted mechanically, manually or chemically, and then the depainted enameled wire and the lead wire are connected by welding. This traditional connection process is not only inefficient, but also prone to problems such as false soldering, and failure to achieve a good seal on the painted part. The copper wire in the lacquer is easily corroded and oxidized, which damages the performance of the motor and affects the use of the product. In the prior art, a terminal with trapezoidal tooth grooves transversely provided on the inner surface is used. When using, put the enameled wire and lead in the terminal and press it tightly by the crimping machine. The transversely arranged trapezoidal tooth grooves pierce the paint layer of the enameled wire, so that the enameled wire and the lead are connected and conducted. However, the processing of the trapezoidal tooth grooves arranged horizontally is troublesome and the shape of the terminal is fixed. Leads with different diameters need to be equipped with terminals of different specifications, which is troublesome to use.

Technical realization elements:
In view of this, the purpose of the present invention is to provide a piercing terminal with a simple structure and convenient crimping.
In order to achieve the above purpose, the utility model adopts a piercing terminal. The cross section of the piercing terminal is U-shaped. The piercing terminal includes two side wing plates, and a semicircular transition plate connecting the two side wing plates. The piercing terminal forms a plurality of tines along the U-shaped line of the inner surface on the inner surface, and a plurality of grooves are formed between the adjacent tines.
The beneficial effects of the utility model are: The whole is set in a U shape, which is more convenient and easy to operate when crimping the utility model. The multiple sharp teeth are used for puncture operation, and the groove is provided to ensure the success of puncture.
The utility model further provides that the adjacent grooves are arranged as an upper groove and a lower groove. The depth of the upper groove is smaller than that of the lower groove. The upper groove is provided to increase the strength, and the lower groove is provided with a large depth, which ensures the accurate puncture operation.
