Wire harness quick-plug 2 + 3 is a common electrical connection device and is widely used in various electronic devices and electrical systems. The following is a detailed introduction to it:

Structure and Principle

Structure: It is usually composed of a male end and a female end. The male end has 2 and 3 protruding pins, while the female end has 2 and 3 recessed sockets accordingly. This design enables the male and female terminals to be precisely matched and inserted, achieving the conduction of the circuit. Pins and sockets are generally made of materials with good electrical conductivity such as copper alloys and undergo surface treatments like gold or silver plating to reduce contact resistance and prevent oxidation.

Principle: By inserting the male pin into the female socket, the conductive components of the two are made to come into close contact, thus forming a current path and achieving the transmission of power and signals. Meanwhile, there are usually locking or interlocking structures between the male and female heads to ensure the stability of the connection and prevent accidental separation due to external forces or other factors during use.

Performance characteristics

Electrical performance: It has excellent electrical conductivity and can withstand certain voltages and currents. The general rated voltage is around 300 to 500V, and the rated current varies depending on the specific specifications, ranging from 2 to 10A. In addition, the contact resistance is low and stable, usually at the milliohm level, to reduce the loss of electrical energy transmission and heat generation.

Mechanical properties: The casing is made of high-strength and impact-resistant engineering plastics such as nylon and PBT, which can withstand certain external force pulling and vibration. Meanwhile, the pins and sockets have a certain insertion and extraction force, which not only ensures the reliability of the connection but also facilitates the user's insertion and extraction operations.

Environmental adaptability: It has excellent temperature resistance and can operate normally within a certain temperature range, generally from -40 ℃ to 100℃. Some products also feature water resistance, dust resistance, corrosion resistance and other properties, and can adapt to harsh working environments.

Application scenarios

Automotive electronics: Wiring harness connections used for sensors, controllers, audio systems, lighting systems, etc. in automobiles. For instance, the airbag system of a car, the engine management system, the on-board multimedia system, etc. may all use this kind of wiring harness quick-plug to achieve reliable electrical connections between various components.

Industrial automation: It is used in the connection between equipment in an automated production line, such as between PLCS and sensors, drivers and motors, etc. The wiring harnesses of different devices can be quickly connected to achieve signal transmission and power supply, improving the operational efficiency and stability of industrial equipment.

Consumer electronics: The connection of some small electronic products or electronic modules is also used. For instance, in devices such as digital cameras, video cameras, and portable hard drives, it is used to achieve power and signal connections between different components, facilitating users' assembly and maintenance of the equipment.

Key points for selection

Electrical parameters: According to the actual application requirements, select products with appropriate rated voltage, rated current, contact resistance and other electrical parameters to ensure that the wire harness quick plug can work safely and reliably.

Mechanical parameters: Consider factors such as insertion and extraction force, housing material and mechanical strength. If there is significant vibration or external force in the application scenario, products with high mechanical strength and appropriate insertion and extraction force should be selected to prevent connection loosening or damage.

Environmental conditions: According to the temperature, humidity, dust, oil stains and other conditions of the usage environment, select the wire harness quick-plug with the corresponding protection level and environmental resistance performance. For example, products used in damp environments should have good waterproof performance.

Size and shape: Select the appropriate size and shape of the wire harness quick-insert based on the installation space and wiring requirements. Ensure that it can be conveniently installed inside the equipment and is compatible with other components.
