Description

Technical Field

[0001] The utility model relates to the technical fields of controllers, drivers and internal wire harness connections, and particularly relates to a structure for replacing a wire harness connection with a PCB board. Background Art

[0002] Broadly speaking, a driver refers to the driving hardware for driving a certain type of device. Nowadays, drivers are getting smaller and smaller. Therefore, in many cases, a driver cannot be made too large. When designing a driver, the dimensions of length, width and height should be fully utilized. In many cases, if a PCB board is designed, there will be structural limitations. Therefore, often several PCB boards are required for one driver. Currently, the connection of signals of several driver boards generally uses wire harnesses.

[0003] Using wire harnesses will have several drawbacks: First, there are many wires that need to be inserted in the wire harness, and it is easy to insert the wire terminals incorrectly. Second, it is troublesome to fix the wires inside the board. When there are many wires, it looks messy at a glance. Third, high-temperature wires are required for the wires. High-temperature wires are expensive and not commonly used at the same time. Fourth, the wire harness needs to be fixed separately on the baffle, which is easy to shake. If too much force is applied, it is easy to push the wire harness plug out of the baffle. Therefore, we propose a structure for replacing a wire harness connection with a PCB board.
