Description

Technical Field

[0001] The utility model relates to the technical field of electronic product component production, in particular to a casing probe installation tool. Background Art

[0002] The sleeve probe is a device used in the field of electronic testing. They are usually used for integrated circuit testing, PCB (printed circuit board) testing, etc. The sleeve probe consists of two parts: the sleeve (needle sleeve) and the probe. The probe is used to contact the test point on the circuit board, while the sleeve protects the probe and provides a certain degree of elasticity. In electronic testing, the sleeve probe can provide a stable contact force to ensure the accurate transmission of the test signal.

[0003] The sleeve probe installation tool is usually used to ensure that the probe is correctly installed in the sleeve. In the prior art, the installation steps of the sleeve probe mainly include: opening a mounting hole on the pin mold fixing plate; inserting the sleeve: inserting the sleeve into the mounting hole of the pin mold fixing plate with the bottom end facing downward, ensuring that the sleeve can easily slide into the hole until the pressure ring contacts the top surface of the mounting plate; knocking the sleeve into the mounting hole of the pin mold fixing plate: inserting the tool head of the sleeve installation tool into the top of the sleeve, and gently tapping with a small hammer until the tool head of the tool contacts the pin mold fixing plate; installing the probe: using the probe installation tool, push the probe vertically downward into the sleeve until the probe is fixed in the sleeve.

[0004] The existing installation method of casing probe has at least the following technical problems:

[0005] (1) The diameter of the mounting hole may be too large or too small, affecting the installation of the casing;

[0006] (2) The sleeve is easily damaged during the process of knocking the sleeve into the mounting hole of the needle mold fixing plate;

[0007] (3) Once the sleeve is knocked into the installation hole, an interference fit structure is formed between the sleeve and the installation hole, and it cannot be replaced. If it needs to be replaced, the existing installation template can only be damaged and a new template can be made and reinstalled, resulting in a waste of manpower, material resources, and installation time costs.
