The four basic structure of the electronic connector, electronic connectors are vulnerable to what corrosive hazards?

As the name suggests, the electronic connector is to connect the circuit. In practice, the product's four basic structures are indispensable, namely, the insulator, accessories, contacts and shells, next we one by one to introduce these institutional parts, I hope that after reading the article, you have a better understanding of the product.
1, insulator
　　The insulator part of the electronic connector is also known as the base or mounting plate, its purpose is to allow the contact can be arranged according to the required spacing and location, to ensure that each contact and the shell can have a good insulation properties between.
　　For electronic connectors, have a better insulation resistance and strong voltage resistance, is very important, so in this part of the construction in the production of insulating materials to be selected.
2, contact parts
　　Contact is one of the core institutions of the electronic connector, which consists of a positive contact and a negative contact composed of contact pairs, through which the two inserted, you can achieve the effect of electrical connection.
　　Usually the positive contact belongs to the rigid parts, it is mainly the use of brass, phosphor bronze production, the shape can be divided into cylindrical, cylindrical and flat.
　　As for the negative contact parts, it needs to rely on the elastic structure, in the insertion of deformation, and the positive contact parts and contact to realize the connection, it has a lot of shapes, there are folding type, cylinder type, cantilever beam type, and so on.
3、Shell
　　It is also the shell part of the electronic connector, the main role is to protect the insulated mounting plate and pins inside, at the same time can provide the alignment of the insertion and closure, and so that the electronic connector can be connected to the equipment above.
4, accessories
　　Electronic connector accessories, including installation accessories and structural accessories two parts, installation accessories are mainly nuts, screws, screws, spring ring, etc., structural accessories are positioning pins, seals, rings, cable clamps, etc..
