1.The connector can be selected according to the straight type,curved type,cable outer diameter,shell fixing requirements,volume,weight and whether to connect metal hose.

2.The connector can be selected according to the appearance,shape and color of the connector.

3.The appropriate connector can be selected according to the actual use of the connector.Generally,the environmental factors affecting the performance of the connector include temperature,humidity,sudden temperature change,atmospheric pressure,corrosive environment,etc.,and the use,storage and transportation environment of the connector will also affect its performance.Therefore,the corresponding connector must be selected according to the actual environmental conditions.

4.The connector can be selected according to the temperature range of the application working environment.The design material of the connector determines the temperature range of its working environment.High temperature will damage the edge material of the connector and reduce the insulation resistance and withstand voltage;The metal contact will make the contact point lose elasticity and accelerate oxidation in the high temperature environment,resulting in the deterioration of the coating.The ambient temperature range of most connectors is usually-55~100℃,and the requirements for special occasions may be higher.

5.The appropriate connector can be selected according to the connection mode.There are many kinds of connector termination modes.Specifically,the actual use and mechanical properties of the connector should be considered to ensure that the selected connector products have high reliable connection.
