Problems solved by technology

[0003] There are certain disadvantages in the use of the existing positioning pins of PCB board test fixtures. First, the use strength of the positioning pins may be low during use, which is prone to damage and has a short service life, which is not conducive to people's use. , in addition, it is relatively complicated to prepare, which brings certain adverse effects to people's use process. Therefore, we propose a PCB board test fixture positioning pin and its manufacturing method

Abstract

The invention discloses a PCB test fixture positioning pin and a manufacturing method thereof, the PCB test fixture positioning pin comprises a pin body, a pin holder and a pin head, the tail of the pin body is provided with a pin tail, the pin body is internally provided with a spring, the end part of the spring is provided with a piston, a pin rod is installed between the pin holder and the pin head, the outer wall of the pin body is provided with a reinforcing shell, and the reinforcing shell is provided with a through hole. The reinforced shell comprises a zinc coating, a metal fiber layer, a high polymer material layer, a copper alloy layer and an aluminum alloy layer, the zinc coating is located on the outer surface of the metal fiber layer, and the metal fiber layer is located on the outer surface of the high polymer material layer. According to the PCB test jig positioning pin and the manufacturing method thereof, the reinforced shell and the galvanized material layer are arranged, so that the use strength of the positioning pin can be improved, damage is not prone to occurring, the service life of the positioning pin is prolonged, the anti-abrasion effect of the outer surface of the positioning pin can be improved, the use strength is further improved, and manufacturing is simpler.

Description

technical field [0001] The invention relates to the field of PCB board testing, in particular to a PCB board testing fixture positioning pin and a manufacturing method thereof. Background technique [0002] PCB board test fixture positioning pin is a kind of support device for positioning the PCB board during testing. When testing the PCB board, it is necessary to locate the four corners of the board first to prevent the deviation during testing. In fact, with the continuous development of technology, people have higher and higher requirements for the manufacturing process of PCB board test fixture positioning pins. [0003] The existing PCB board test fixture positioning pins have certain disadvantages in use. First of all, the use strength of the positioning pins may be low during use, which is prone to damage and has a short service life, which is not conducive to people's use. , and also, the preparation is more complicated, which brings certain adverse effects to peopl...
