1. Self-locking mouth

The locking device of the terminal in the sheath, the self-locking opening of the conventional terminal generally has 3 positions, the front of the terminal, the back of the terminal, and the two sides of the terminal. outside the jacket).

2. Wire core crimping area

The contact area of ​​the wire conductor and the terminal through which current and signals are transmitted between the terminal and the wire and electrical appliances. It is also the most important area to ensure electrical and mechanical properties.

3. Insulation crimping area

The contact area between the wire insulation layer and the terminal, this area has two functions:

① Prevent the wire core from being exposed at the end of the sheath caused by the retraction of the wire insulation layer, and the phenomenon of arc connection short circuit occurs in the case of high voltage;

②After the terminal tail in the insulation crimping area is in contact with the wire wrap, limit the swing range between the wire and the terminal to prevent the possibility of the wire core being broken due to the large swing.

4. Fixed navigation

A guide device when the terminal is installed in the sheath, the main functions of the fixed guide rail are 2:

① When the terminal is installed in the sheath, it plays a guiding role;

②After the terminal is installed in the sheath, it plays the role of fixing the terminal, so that the terminal cannot rotate or swing left and right in the sheath, so as to ensure the assemblability and stability of the terminal and the terminal, and the terminal and the sheath.

5. Tape cutting point

The position where the crimping die separates the terminal and the strip during the cold stamping connection process.

6. Front and rear protection ports

In the process of cold stamping connection, in order to protect the wire core from being damaged in the crimping area of ​​the wire core, the protrusion is left after being squeezed and deformed during the crimping process.

7. Crimp out

After the wire and the terminal are connected by cold stamping, the wire core in front of the front protection port is the wire core in the transition area.
