terminal block
terminal block is an electronic component used for circuit connection, also called terminal block, electrical connector, etc.
shell
electrical connector shell refers to the plug socket shell, connecting nut, tail accessories. The function of the shell is to protect the internal parts of the electrical connector such as the insulator and the contact body (the general name of the pin socket) from damage. The positioning keyway on the top ensures the positioning of the plug and socket. The coupling nut is used to attach and detach the connector. The tail attachment is used to protect the wire and contact body terminal from damage and to fix the cable. The shell also has a certain electromagnetic shielding effect. The shell is generally made of aluminum alloy processing (machining, cold extrusion, die casting). Steel housings are mostly used for glass sealing and high temperature resistant electrical connectors.
insulator
insulator consists of pin insulator and socket insulator. Interface seal body, seal body, etc. It is used to keep the pin socket in a set position and electrically insulate each contact body and each contact body and the housing. The environmental resistance of the electrical connector is improved by sealing the insulator and the interface seal body. In order to adapt to the product's high temperature, low temperature, flame retardant, to ensure that the geometry of the parts is stable and reliable. Most insulators are molded using thermosetting plastics. The interface grommet and seal are molded with silicone rubber.
contact body
pin socket is a general term for contact body, which is divided into welding type, crimping type and winding type, etc., which are used to realize circuit connection. The pin jack is the key component of the electrical connector, which directly affects the reliability of the electrical connector. Most of the pin jacks are made of elastic copper alloy material with good electrical conductivity, and the surface is silver-plated and gold-plated to achieve the purpose of small contact resistance and corrosion prevention. The structural features of
are: environment resistance, bayonet type (quick) connection, multi-key position (anti-wrong insertion), crimping connection between contact body and wire (single pick-up and delivery is convenient for fault handling). The shell is shielded and the environment is protected with 360 ° electromagnetic interference shielding capability.
