The base of the terminal connector, that is, the plastic part of the product, its role is to support the contact parts - conductive parts and make it firm and not loose, in addition to the whole terminal for the plastic parts can also play a dustproof, anti-fouling and moisture-proof, so the general high-quality product base plastic parts will choose V0 material with high protection level. The base body can be installed with needle and hole conductors, and the wire is connected from one half of the connector and from the other half, so it can be called male head and female head. Talk about the base, is generally a general term for connectors with welding pins that can be directly installed on the printed circuit board, the main difference between the base and the base body is that the base is always installed with the circuit pin, and the base body is just an empty shell.
Another important part is the conductive part of the terminal connector, its role is to connect the two parts of the conductor (or wire) together, the circuit is connected, and the current flows through the connector. There are two main types of contact parts: terminal and pin. The exact shape of the object varies greatly.
One product that comes with the terminal connector is the circuit identification, because the connector always has many circuit pins, there must be a way for the user to correctly recognize the pin number of the circuit.
