The automotive wiring harness is the network body of the automotive circuit, connecting the electrical and electronic components of the car and enabling them to function. Without the wiring harness, there would be no automotive circuit.
With the development of intelligent technology, there are more and more wiring harnesses in cars. Although they are almost invisible from the appearance of the car, they are hidden in every corner of the car body. Many people have such questions, how to ensure stable connection of so many wiring harnesses in the car? Wire-to-wire connectors can stably connect the long wire harnesses together according to certain requirements to provide energy for various parts of the car.
What types of wire-to-wire connectors are there? From the application point of view, they can be divided into non-waterproof wire-to-wire connectors, waterproof wire-to-wire connectors and body-to-door wire-to-wire connectors.
01
The non-waterproof series is mainly installed under the vehicle frame or in the cockpit. Because the outside of these locations is tightly wrapped by the frame or shell and will not be exposed to the external environment during daily driving, it is not necessary to adopt a waterproof structure due to space, weight and cost considerations.
Common non-waterproof applications include connections from automotive instruments to the engine compartment, body, and roof, and from the body to the engine compartment and trunk.
The non-waterproof series wire-to-wire connector is the most commonly used wire-to-wire connector in automobiles. It is widely used in various parts of automobiles due to its compact size, economical cost and rich PIN positions.
02
As the name implies, the body-to-door series is used to connect the wiring harness between the body and the front/rear doors. Nowadays, there are more and more buttons on the car doors, and the corresponding applications are also increasing. Not only do they correspond to door locking, window lifting, and rearview mirror adjustment, but some models also integrate buttons for more functions such as seat adjustment, rearview mirror defogger, volume adjustment, and central control screen control on the car doors.
This requires that the wiring harness connections on the car doors be more compact, and the body-to-door connectors must not only be smaller in size, but also meet more requirements beyond traditional functions, such as data transmission needs, especially the transmission of screen analog signals.
The new generation of body-to-door series connectors developed by TE Connectivity (TE) has a built-in modular structure and reserved holes for coaxial connectors and automotive Ethernet connectors, which can easily replace FAKRA coaxial connections, MATE-AX miniaturized coaxial connections and MATEnet Ethernet connections, leaving more room for functional development for flexible design.
03
The waterproof series of wire-to-wire connectors are mainly used in working conditions where the connection parts may be exposed to the outside or may be exposed to water, especially the wiring harness connection between the front and rear bumpers and the engine compartment and the body. The waterproof connector is equipped with a strict protective plastic shell and sealing ring, and uses a dedicated waterproof terminal, with multiple protections and worry-free.
Since the application environment of automotive electronic systems is relatively harsh, there are high requirements for the safety and reliability of automotive connectors. Therefore, the selected connectors must be resistant to high temperature, vibration, impact and corrosion.
