The electrical connector is an electromechanical element connected to an electrical circuit. So the electrical connector itself is the electrical parameters of the choice of electrical connector first to consider the problem. Proper selection and use of electrical connectors is an important aspect of ensuring circuit reliability.

Electrical connector safety parameters:

1. Atmospheric pressure

In the air at high altitude, plastic emissions of gas pollution contact, and to increase the trend of corona, pressure resistance decreased, so that the circuit short circuit failure. At high altitude to achieve a certain value, the plastic performance deteriorated. So the use of non-sealed electrical connector at high altitude, must be derated.

2.Corrosive environment

According to the different use of the electrical connector corrosion environment, the choice of the corresponding metal, plastic, plating structure of the electrical connector, like salt spray environment in the use of the electrical connector, if there is no corrosion of the metal surface, the performance will deteriorate rapidly. In a SO2 environment with a considerable concentration, it is not advisable to use an electrical contact with silver. In hot flashes, mold is also an important issue.

3.Termination method

Termination means that the contact of the electrical connector is connected to the wire or cable. Reasonable choice of termination and proper use of termination technology, but also the use and selection of electrical connector is an important aspect.

4.welding

The most common welding is soldering. The most important thing for the solder connection is the continuity of the metal between the solder and the surface to be welded. So for the electrical connector, it is important to solderability. The most common coating is the tin alloy, silver and gold. Reed-type contact with the common welding end with a solder-type, punching type and notch Solder type: pinhole contact on the common welding end with a circular arc notch.
