Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and in particular to a portable PCB board detection jig. Background Art

[0002] PCBs are widely used in various electronic devices, including computers, mobile phones, televisions, automotive electronics, medical equipment, etc. PCBs provide a convenient, compact and reliable way to connect various electronic components together to form a complete circuit. With the continuous advancement of electronic technology, PCBs are also constantly developing. In recent years, new PCB technologies such as flexible PCBs, high-density interconnected PCBs, and high-speed PCBs have continued to emerge to meet the demand for smaller, higher-performance, and more complex circuits. Before PCB boards are put into use, they need to be tested. Therefore, a portable PCB board testing fixture is proposed.

[0003] A search revealed a publication numbered CN208047009U, which discloses a PCB jig comprising a base, a PCB jig platform, a crossbeam, a crossbeam support, and a push rod. The PCB jig platform is horizontally arranged directly above the base surface, and the base surface has four blind holes in a rectangular array. A guide hole is also coaxially provided at the bottom of each blind hole, and the guide hole has a diameter smaller than that of the blind hole. Four guide posts are vertically arranged at the bottom of the PCB jig platform, and the lower ends of the four guide posts are movable and extend into the four guide holes. Each guide post is sleeved with a support spring, and the lower end of the support spring presses against the bottom of the blind hole, while the upper end of each support spring supports the PCB jig platform. The utility model has a simple structure. In the clamping state of the jig, the push rod is always subjected to a stable rebound preload due to the rebound force of the support spring, and the threaded connection between the push rod and the crossbeam is not easily loosened.

[0004] In the above application, due to the rebound force of the support spring, the push rod is always subjected to a stable rebound pre-tightening force, so that the threaded connection between the push rod and the crossbeam is not easy to loosen. However, during use, the different sizes of PCB boards are not taken into account, making it inconvenient to adjust the clamping in time. Utility Model Content
