There are many types of connectors and various shapes. When we usually choose connectors, we can choose from the following aspects:
1. Choose the connector from the straight shape, the curved shape, the outer diameter of the wire or cable and the fixing requirements with the shell, the volume, the weight, whether to connect the metal hose, etc.
2. Choose from the appearance, shape and color of the connector.
3. Choose the connector according to the actual situation of use. Environmental parameters mainly include ambient temperature, humidity, sudden temperature changes, atmospheric pressure, and corrosive environment. The environment in which the connector is used, stored, and transported has a great influence on its performance, so the corresponding connector must be selected according to the actual environmental conditions.
4. Choose the connector according to the working environment temperature of the connector. The metal material and insulating material of the ambient temperature connector determine the working environment temperature of the high-current connector. High temperature will destroy the edge material, causing the insulation resistance and pressure resistance to decrease; for metals, high temperature can make the contact pair lose its elasticity, accelerate oxidation and cause coating deterioration. The usual ambient temperature is -55~100℃, which may be even higher in special occasions.
5. Choose the connector according to the connection method. Termination mode refers to the connection mode between the contact pair of the high-current connector and the wire or cable. Reasonable choice of termination methods and correct use of termination technology are also an important aspect of the use and selection of connectors.
