What is Automotive Connectors

The harness connector is a kind of terminal. The connector, also known as the connector, is composed of plug and socket. The connector is the relay station of the neutral harness of the automobile circuit. Generally, connectors are used for the connection between harnesses and harnesses, and between harnesses and electrical components. Automobile harness connectors are important components for connecting various electrical and electronic equipment of the automobile. In order to prevent the connectors from being disconnected during the driving of the automobile, locking devices are used for all connectors.

To disassemble the connector, first release the locking, and then pull the connector. It is not allowed to force the cable harness without releasing the locking, which will damage the locking device or the connecting harness.

Selection of Automotive Connectors

In modern automobiles, there are many automobile harnesses, and the electronic control system is closely related to the harness. Someone once made a vivid analogy: if the functions of microcomputer, sensor and actuator are compared with human body, it can be said that microcomputer is equivalent to human brain, sensor is equivalent to sensory organ, actuator is equivalent to motor organ, harness is nerve and blood vessel, and connector is the body connecting blood vessel and body.

The type selection of connector needs to ensure good contact performance with electrical components, minimize contact resistance and ensure electrical reliability. The contact modes of connectors mainly include wire to wire, wire to board, board to board. 1. Wire to wire refers to the connection mode that forms an electrical connection between wires; 2. Wire to board refers to the connection between wires and equipment; 3. Board to board refers to the input end connection connected to the outside of the equipment, including PCB end connection and electrical equipment end connection. Selection method of connector: according to different connection modes, how to select a suitable connector should first make a preliminary judgment on the basic performance of the connection according to the application environment, and consider the installation environment, such as vehicle engine room and cabin, low pressure and high pressure, dry and wet, in the trunking and at the body through-hole, and select the seal, waterproof plug, locking and interlocking structure of the connector according to the above requirements Add fixed clips, etc. For the performance requirements of connectors and supporting terminals, it is necessary to further screen them in combination with the cross-sectional area of wires and the size of passing current. The current that can be carried by connectors of different specifications can be judged according to the routine: the terminal width is 0.64-1, and the series carries 10A; Width 2.2-2.8 carrying current 20A; Width 4.8 bearing capacity 30A; Width 6.0-6.3 bearing capacity 45A; Width 7.8-9.5, bearing capacity 60A; The carrying current of the terminal usually needs to be matched with the wire diameter. If too large terminal is selected and the wire diameter does not match, too large voltage drop will be caused; If too small terminal and wire diameter are selected, the contact resistance will be too large, and the rapid temperature rise will easily cause the connector to melt.

During model selection, if you need to refer to detailed connector drawing data and models, you’d better go to the official website, such as te, APTIV, Sumitomo, etc. to cooperate with the original factory can not only get the support of sample and get good material prices, but also get the support of existing comprehensive application cases and detailed data in the product development stage.


Basic Structure of Automobile Connector

Four basic structural components of automobile connector

1、 The contact is the core part of the automobile connector to complete the electrical connection function. Generally, the contact pair is composed of male contact and female contact, and the electrical connection is completed through the insertion of female and male contact.

The male contact is a rigid part, and its shape is cylindrical (round pin), square cylinder (square pin) or flat (insert). Male contacts are generally made of brass and phosphor bronze. The female contact, namely the socket, is the key part of the contact pair. It relies on the elastic structure to produce elastic force when it is inserted with the pin to form close contact with the male contact and complete the connection. There are many types of jacks, including cylindrical (slotted, necked), tuning fork, cantilever (longitudinally slotted), folded (longitudinally slotted, 9-shaped), box (square jack) and hyperboloid spring jacks.

2、 The shell, also known as the shell, is the outer cover of the automobile connector. It provides mechanical protection for the built-in insulating mounting plate and pin, and provides the alignment when the plug and socket are inserted, so as to fix the connector to the equipment.

3、 Insulator, which is also often called automobile connector base or insert. Its function is to arrange the contacts according to the required position and spacing, and ensure the insulation performance between the contacts and between the contacts and the shell. Good insulation resistance, voltage resistance and workability are the basic requirements for selecting insulating materials to be processed into insulators.

4、 Accessories, including structural accessories and installation accessories. Structural accessories such as snap ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring, sealing gasket, etc. Install accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories are standard parts and general parts.
