Introduction to the four basic components of automotive connectors

Release time: 2017-02-25 Clicks: 1844

1. The housing is the outer cover of the car connector . It provides mechanical protection for the built-in insulation mounting plate and pins, and provides the alignment of the plug and socket when mating, thereby fixing the connector to the device.


2. Contacts are the core parts of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a positive contact and a negative contact, and the electrical connection is completed by the mating of the female and male contacts. The male contact is a rigid part whose shape is cylindrical (round pin), square cylinder (square pin) or flat (pin). The male contact is generally made of brass or phosphor bronze. The female contact is the key part of the contact pair. It relies on the elastic structure to elastically deform when mating with the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many types of jack structures, including cylindrical (split groove, necked), tuning fork, cantilever beam (longitudinal slotted), folded type (longitudinal slotted, 9-shaped), and box-shaped (square socket) And hyperbolic wire spring jacks.


3. Insulators, insulators are often referred to as automobile connector bases or inserts. Its role is to arrange the contacts at the required position and spacing, and to ensure that the contacts and contacts are in between. Insulation performance with the shell. Good insulation resistance, voltage resistance performance and easy processability are the basic requirements for selecting insulating materials for processing into insulators.


4. Attachments, attachments are divided into structural attachments and installation attachments. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories have standard parts and universal parts. It is these four basic structural components that enable the automotive connector to act as a bridge for stable operation.
