Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit boards, in particular to a PCB circuit board with a wire harness fixing structure. Background Art

[0002] PCB is a printed circuit board, also known as a printed circuit board. It is the provider of electrical connections for electronic components. The current circuit board is mainly composed of lines and drawings. The lines are used as a tool for conducting between the originals. In the design, a large copper surface will be designed as a grounding and power supply layer. The lines and drawings are made at the same time. The insulating board is used as the base material and cut into a certain size. At least one conductive pattern is attached to it, and holes (such as component holes, fastening holes, metallized holes, etc.) are arranged on it. It is used to replace the chassis of the previous electronic components and realize the mutual connection between electronic components. Since this board is made by electronic printing, it is called a "printed" circuit board. It is not accurate to call "printed circuit board" as "printed circuit" because there is no "printed component" but only wiring on the printed board. The PCB circuit board is the support of electronic components and provides electrical connections between electronic components. It is an indispensable part of all electronic devices, so ensuring its stability and reliability is crucial to the performance of the entire device. In the three-dimensional layout design of the wire harness, how to effectively fix the wire harness, control the direction of the wire harness, and maintain appropriate clearance with surrounding parts is a key and difficult point in the design process. If the wire harness is not properly fixed, it may cause poor contact or signal interference, affecting the normal operation of electronic equipment.

Such methods are complicated and troublesome when disassembling and replacing. Therefore, we propose a PCB circuit board with a wiring harness fixing structure to solve this problem.
