What Are The Basic Components of Waterproof Connector?

The internal structure of a machine is very complicated and complicated, and the components of the machine and underwater camera equipment cannot be separated from connectors. It commonly used connectors include: SIM card holder, SD/TFC card holder, SATA connector, board-to-board connector, PCIE connector, USB connector, etc. These waterproof connectors have become indispensable electronic accessories. The use performance, specifications and dimensions of electronicare different. 

The following is a detailed introduction by science and technology to which connector products are mainly used: players, automobiles and automobile peripheral products, unmanned aerial vehicles, recorders, security equipment, medical equipment, and many other uses.

The basic structural components of the connector are: contacts, housings, insulators and accessories.

1. Contacts are the core parts of the connector to complete the electrical connection function. Generally, the contact is made up of two parts of male contact and female contact, and the electrical connection is completed through the insertion of the male and female contacts.

The male contact is a rigid part, in which the shape is divided into cylindrical (round pin), square cylindrical, or flat. Male contacts are generally made of brass or phosphor bronze.

Female contact piece, i.e. jack, is the key part of contact. it relies on the elastic structure to generate elastic deformation when it is inserted into the pin to generate elastic force to form close contact with male contact piece to complete connection. There are many types of jack structures, including cylinder type, tuning fork type, cantilever type, box type, etc.

2. Shell: Also called shell, that is, the outer cover of the connector, which provides mechanical protection by the built-in insulating mounting plate and pin, and provides proper alignment of plug and socket to fix the connector to the equipment

3. Insulator: Insulator is called base or mounting plate. Its function is to arrange the contacts according to the position and spacing required by the lock, and to ensure the insulation performance between the contacts and the shell of the contacts. Good insulation resistance, point pressure resistance and easy processing are the basic requirements for selecting insulation materials to be processed into insulation.

4. Accessories: Accessories include structural accessories and installation accessories. Structural accessories include circlip, locating key, locating pin, guide pin, coupling ring, cable clamp, sealing ring and sealing gasket. Install accessory milk screws, nuts, screws, spring rings, etc. Most accessories are standard parts and common parts.
