Automotive connectors are a component that our electronic engineers and technicians often come into contact with. Its function is very simple: to build a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. The form and structure of automotive connectors are ever-changing. It is mainly composed of four basic structural components, namely: housing (depending on the variety), contacts, accessories, and insulators.

  Automotive connectors are a component that our electronic engineers and technicians often come into contact with. Its function is very simple: to build a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. The form and structure of automotive connectors are ever-changing. It is mainly composed of four basic structural components, namely: housing (depending on the variety), contacts, accessories, and insulators.

  1. The shell, also known as the shell, is the outer cover of the automotive connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are mated, and then fixes the connector. to the device.

  Second, the contact piece is the core part of the automotive connector to complete the electrical connection function. Generally, a contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed through the insertion of the female and male contacts. The male contact is a rigid part, its shape

  The shape is cylindrical (round pin), square column (square pin) or flat (insert). Male contacts are generally made of brass, phosphor bronze. The female contact piece is the jack, which is the key part of the contact pair, and it relies on the elastic structure to fit with the pin

  When elastic deformation occurs, elastic force is formed to form close contact with the positive contact piece to complete the connection. There are many types of jack structures, such as cylindrical type (splitting, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9

  font), box-shaped (square jack) and hyperboloid wire spring jack, etc.

  Three, accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Installation accessories such as screws, nuts, screw rods, spring rings, etc. Most of the accessories have standard parts and general parts.

  Fourth, insulators, insulators are also often called automotive connector bases (base) or installation boards (insert), its function is to arrange the contacts according to the required position and spacing, and to ensure that the contacts between the contacts and the contacts Insulation performance between the shell and the shell. Good insulation, both ends take combination screw.
