Automotive connector is a component of electronic engineering technician regular contact. Its role is very simple: in the circuit between blocked or isolated place unreasonable circuit, bridge the communication gap, allowing current to flow, the circuit to achieve a predetermined function. Automotive Connectors form and structure is changing, which is mainly composed of four basic structural components, namely: contacts, housing (depending on species may be), insulator, annex.
About Automotive Connectors
General car need to use the type of connector has nearly 100 kinds, connectors used a single model, about hundreds of as much. As the car safety, environmental protection, comfort, wisdom, and so increasingly high demand, the increasing application of automotive electronics products, which will allow automotive connectors showing growth of the number of applications in the case.
The basic structure
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.
