The 4-core male and female quick-plug connector for wire harnesses is a type of connector used for wire harness connections. The following is its related introduction:

Structural characteristics

Male connector: It usually has a protruding pin, and its shape may be cylindrical, square cylindrical or flat, etc. It is used to insert into the socket of the female connector to achieve electrical connection.

Female connector: It has a recessed socket. Common socket types include cylindrical, tuning fork, and cantilever beam types, etc. It can tightly accommodate the male connector pins, ensuring the stability and reliability of the connection.

Shell: Generally, high-strength and well-insulating materials such as nylon and PPS are used to protect the internal conductive components, prevent short circuits and external interference. At the same time, it has a certain mechanical strength and can withstand certain external force pulling and impact.

Performance parameters

Rated voltage: Generally around 300-500V. Products from different manufacturers and in different application scenarios may vary. It is used to indicate the voltage range that the connector can safely withstand.

Rated current: Usually 2-10A. The specific value depends on factors such as the material of the wire core, cross-sectional area, and the structural design of the connector. It reflects the maximum current value that the connector can carry.

Contact resistance: It is required that the contact resistance be low and stable, generally at the milliohm level, to reduce the loss and heat generated during the transmission of electrical energy and ensure the efficiency of signal and power transmission.

Insulation resistance: Usually greater than 100MΩ. Good insulation resistance can effectively prevent leakage and short circuit phenomena, ensuring safe use.

Application field

Automotive electronics: It is used for the connection of wiring harnesses of various sensors, controllers, audio systems, lighting systems, etc. in automobiles, such as the wiring harness connection of automotive cameras, reversing radars, in-car navigation devices, etc. It can work stably in the complex electrical environment of automobiles, ensuring the accuracy and reliability of signal transmission.

Industrial automation: It is widely applied in the wiring harness connection between sensors, actuators, programmable logic controllers (PLCS) and other devices in automated production lines. It can adapt to harsh conditions such as vibration, shock, dust and oil stains in industrial environments, ensuring the stable operation of industrial equipment.

Consumer electronics: In electronic products such as mobile phone chargers, headphones, and portable hard drives, it is used to achieve power and signal connections between different components. It has the advantages of small size and convenient connection, and can meet the requirements of consumer electronics for thinness, miniaturization, and convenience.

Advantages

Quick connection and disassembly: Without the need for tools, the male and female heads can be quickly inserted or separated, facilitating installation, maintenance and repair, and improving work efficiency.

Good compatibility: As long as they are 4-core male and female quick connectors of the same specification and type, products from different manufacturers are usually compatible with each other, facilitating connection and replacement in different devices and systems.

Anti-misinsertion design: By using specific shapes, colors or positioning structures, it prevents the male and female connectors from being inserted in reverse or incorrectly, ensuring the correctness and security of the connection.
