Automotive connector is a kind of part that we electronic engineering technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the predetermined function. The form and structure of automotive connectors are ever-changing, which is mainly composed of four basic structural components, namely: housing (depending on the variety), contacts, accessories, and insulators.
Automotive connector is a kind of part that we electronic engineering technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the predetermined function. The form and structure of automotive connectors are ever-changing, which is mainly composed of four basic structural components, namely: housing (depending on the variety), contacts, accessories, and insulators.
The shell, also known as the shell (shell), is the outer cover of the automotive connector, which provides mechanical protection for the internal insulation mounting plate and pin, and provides alignment when the plug and socket are inserted, and then fixes the connector to the device.
Second, the contact part is the core part of the automobile connector to complete the electrical connection function. Generally, the contact pair is composed of positive contacts and negative contacts, and the electrical connection is completed through the insertion of Yin and Yang contacts. The positive contact is a rigid part, and its shape
The shape is cylindrical (round pin), square column (square pin) or flat (insert). Positive contacts are generally made of brass or phosphor bronze. The negative contact piece, the jack, is the key part of the contact pair, which relies on the elastic structure to insert with the pin
When the elastic deformation occurs, the elastic force is generated to form close contact with the positive contact to complete the connection. There are many types of jack structures, including cylinder type (wedge, taper), tuning fork type, cantilever beam type (longitudinal slot), folding type (longitudinal slot,9
Font), box shape (square jack) and hyperboloid wire spring jack.
Three, accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as fasteners, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most accessories have standard parts and universal parts.
Insulator, insulator is also often called the automotive connector base (base) or installation plate (insert), its role is to make the contact parts arranged according to the required position and spacing, and ensure the insulation performance between the contact parts and the contact parts and the shell. Good insulation, both ends take combination screw.
