There are 5 common wiring methods for automotive terminal welding:

 1. Puncture the connection

Also known as insulation displacement connection, it has the characteristics of high reliability, low cost, convenient use, etc., and is suitable for the connection of ribbon cables.

It is not necessary to strip the insulation layer of the cable when connecting, and rely on the "U" shaped touch reed of the terminal to Pierce the insulation layer, so that the conductor of the cable slides into the groove of the touch reed and is caught, thus forming a tight electrical connection.

2, screw connection

The screw connection is the connection method of the screw type automobile terminal welding bar, pay attention to the small section of the allowed connection wire, and the tightening torque allowed with different specifications of screws.

3. Crimp

Crimping is a technique for tightening and displacing metal within regular limits and connecting wires to touch pairs. Good crimping joint can trigger metal interfusion activity, so that the wire and touch data symmetrical deformation.

This connection is similar to cold welding connection, can get better mechanical strength and electrical continuity, can accept more harsh environments. However, the crimping connection is a permanent connection and can only be used once.

4. Welding

The most common welding is tin welding, and the most important connection is that the continuity of the metal should be formed between the solder material and the welded surface. Therefore, for automotive terminal welding and cord end terminals, it is important to weldability.

5. Wrap

Winding is to wrap the wire directly around the angular touch piece winding column. When winding, the wire stops winding under the condition that the tension is controlled, presses into and is fixed at the corner of the winding column of the touch piece to form an airtight touch.
