[0039] In the above technical solution, the wiring harness socket is connected to the wiring harness plug, and the multiple wiring harness sockets include a power socket connected to the power supply and multiple branch sockets. The branch sockets are connected to various components of the electric vehicle (horn, turn signal, instrument, etc.) to provide power to each component.

[0040] The power socket and the branch socket are connected through a circuit board. After the power socket is connected to the power source, power can be supplied to the components on the branch socket.

[0041] Through the above splitters, centralized power management can be achieved, the wiring of the electrical system is simplified, the maintainability and scalability of the system are improved, and the assembly cost is also reduced.

[0042] Specifically, the branching socket includes at least one two-hole socket, at least one four-hole socket, at least one six-hole socket and at least one ten-hole socket.

[0043] The branching socket includes at least one two-hole socket, at least one four-hole socket, at least one six-hole socket and at least one ten-hole socket to meet the connection requirements of different types and quantities of electrical components. In addition to the above conventional number of holes, sockets with more holes such as 12 holes and 14 holes can be set according to actual needs.

[0044] Specifically, the back side of the adapter plate is provided with pinhole columns 7 corresponding to the pinholes one by one, and a reinforcing step 8 is provided between the pinhole columns 7 .

[0045] In this embodiment, pinhole columns corresponding to the pinholes are provided on the back of the adapter plate, and reinforcing steps are provided between the pinhole columns to enhance the structural stability. The design of the reinforcing steps increases the mechanical strength of the adapter plate, ensuring that it will not be deformed or damaged due to vibration or external force during long-term use, thereby extending the service life of the product.

[0046] Specifically, the back of the adapter board has a support column 9 that is higher than the back of the adapter board. The circuit board is placed on the support column 9. The pin is plugged into the circuit board and has a raised welding end 10.

[0047] In this embodiment, a support column that is higher than the back of the adapter board is provided on the back of the adapter board, and the circuit board is placed on the support column to leave a gap between the circuit board and the back of the adapter board to prevent the solder from corroding the adapter board during wave soldering and making it impossible to use automatic soldering. In addition, the pins are plugged into the circuit board and have a raised soldering end, which also facilitates wave soldering and improves soldering stability. This design optimizes the product's soldering process, improves soldering efficiency and soldering quality, and is particularly suitable for large-scale production and automated production line applications, greatly reducing the cost of mass production of products and greatly improving corporate benefits.

[0048] Specifically, it also includes a back cover 11, a connecting ring 12 is provided on the side wall of the back cover 11, and a connecting step 13 connected to the connecting ring is provided on the outer side of the adapter plate.

[0049] In this embodiment, the splitter further includes a back cover, a connecting ring is provided on the side wall of the back cover, and a connecting step matching the connecting ring is provided on the outer side of the adapter plate, so that after the back cover is covered on the adapter plate, the connection is made through the connecting step and the connecting ring.

[0061] In the above technical solution, a sealing cover and a sealing gasket are provided on the wiring harness plug, and a wire hole for the wire to enter is provided on the sealing cover and the sealing gasket. After the wire passes through the wire hole of the sealing gasket, the wire and the wire hole are squeezed, which can prevent rain and dust from entering through the wire hole, thereby improving the waterproof and dustproof effect. In addition, in order to facilitate the plug-in adaptation of the socket with the same number of holes as above (such as multiple two-hole sockets), the sealing gasket can be pad printed in the same color as the socket as an adaptation mark. At the same time, the sealing cover is made of transparent material to facilitate the observation of the adaptation color.
