Abstract

An embodiment of the invention discloses a screw tooth-equipped test pin used for solving a problem that an opening of a pin tube of a screw tooth-equipped test pin of the prior art requires closing-in technologies and production difficulty is increased. The screw tooth-equipped test pin disclosed in the embodiment of the invention comprises a pin shaft, a pin tube, a spring and a clamping ring, wherein the clamping ring is arranged on an inner wall of an opening end of the pin tube, the pin shaft comprises a test head part and a tail end part, the tail end part is tightly clamped in the pin tube via the clamping ring, the test head part extends beyond the opening end of the pin tube, the spring is arranged in the pin tube, and the spring is connected with the tail end part. According to the test pin in the embodiment of the invention, the clamping ring is arranged to replace the closing-in technology in the technologies of the prior art, assembling processes are simplified, production difficulty is greatly lowered, production efficiency is improved, and production costs are reduced.

Description

technical field [0001] The invention relates to the technical field of electronic test needles, in particular to a test needle with screw teeth. Background technique [0002] Test pins, also known as probes in the industry, are divided into pogo pins (special pins) and general pins when used for PCB board testing. Under normal circumstances, a mold can only test one type of PCB board; when the general-purpose needle is used, it only needs to have enough points, so many manufacturers are using general-purpose needles; spring needles are divided into PCB board probes according to the usage , ICT probes, BGA probes, PCB board probes are mainly used for PCB board testing, ICT probes are mainly used for online testing after plug-in, BGA probes are mainly used for BGA package testing and chip testing. [0003] In order to cope with various test products, it is necessary to use the test with screw teeth to test the products. However, the current test needle with screw teeth needs ...
