In the process of interconnecting automotive waterproof connectors, different shapes and modelsconnectorThe devices that are paired and connected are also different. To prevent errors when connecting car waterproof connectors, the following are some common connection methods.

1、 Twisted pair cable

A type of cable consisting of two insulated small conductors wrapped around a layer of casing, usually with good insulation. Ordinary telephone cables and household wires are twisted pair.

2、 Coaxial cable

It is coaxial arrangement of smaller diameter copper wires (inner conductors) on larger diameter outer conductors. Two wires are separated and supported by a dielectric material, and their outermost layer is coated with insulating material.

3、 Discrete conductor

Use a single wire or cable combined with a plastic casing to rivet the terminal connection.

4、 Ribbon cable

This type of cable is called a flat cable, which consists of a set of parallel conductors wrapped in insulating material. There are two types of conductors, one is a circular cross-section conductor, and the other is a flat flexible cable:

1. Printed circuit board (PCB) is printed on a copper plated polymer board through an etching process, and then printed on the circuit.

2. Flat flexible cables (FFC/FPC) are similar to ribbon cables, but their conductors are flat and non circular, with a rectangular cross-section and very thin.
