Four basic structural components of automobile connector
First, the contact is complete automotive connector electrically connected to the function of core components. Usually by the positive contact and the negative contact contact pair composed by male and female mating contacts complete the electrical connection.
The positive contact of rigid parts, which shape is cylindrical (round pins), square column (square pin) or flat shape (inserts). Positive contacts generally made of brass, phosphor bronze. I.e. negative socket contact, a contact of the key parts, it relies on an elastic structure with the pin insertion timely elastically deformed to generate resilient force into close contact with the positive contact to complete the connection. Many types of jack structure, a cylindrical type (split groove, necking), tuning fork, cantilever type (vertical slot), folding type (longitudinal slot, 9-shaped), box-shaped (square jack) and hyperboloid wire spring jack and so on.
Second, housing, also known as shell (shell), automotive connector housings, which provides mechanical protection for the built-in mounting plate and pin insulation and provides plug and socket plug timely alignment, thereby fixing the connector to the device.
Third, the insulator, the insulator is also often referred to as Auto connector base (base) or mounting plate (insert), its role is to make contacts arranged by location and spacing needed and ensure contacts and contacts between insulation properties and housing. Good insulation resistance, withstand voltage performance and ease of processing is to select the insulating material into the insulator of the basic requirements.
Fourth, the attachment, the attachment points structural attachments and mounting accessories. Such as a collar, positioning key, pin, guide pin, coupling ring, cable clamps, seals, gaskets and other structural attachments. Installation accessories such as screws, nuts, screws, spring ring. Annex large have standard and common parts.
It is these four basic structural components of the automobile connector can act as a bridge, stable operation.
