Pogo pin mold, machining process thereof and pogo pin assembly process

Abstract

The invention provides a pogo pin mold, a machining process thereof and a pogo pin assembly process. The pin mold comprises a lower cover plate and an upper cover plate, wherein a square lug boss protrudes from one side of the surface of the lower cover plate; the other side of the surface of the lower cover plate is provided with a plurality of lower through holes along the length direction of the lower cover plate; along the thickness direction of the lug boss, one side of the lug boss is provided with a plurality of lower pinholes for the pogo pin to pass through; corresponding to the lower cover plate, the upper cover plate is provided with upper pinholes and upper through holes in the surface of the upper cover plate, wherein the upper pinholes correspond to the lower pinholes, and the upper through holes correspond to the lower through holes; the upper cover plate adheres to the other surface, provided with the lug boss, of the lower cover plate; a fixing part passes through the upper and lower through holes to realize connection between the upper cover plate and the lower cover plate; and the pogo pin penetrates out of the upper pinholes of the upper cover plate from the lower pinholes of the lower cover plate. The machining process of the pin mold is optimized, and errors generated in a machining process are reduced to improve the machining precision; by adopting a more reasonable high-precision assembly process, the work efficiency of assembly is improved; and the pin mold is simple in structure, low in production cost and good in economic benefits.

Description

technical field [0001] The invention relates to a pogopin probe needle mold, its processing technology and probe assembly technology. Background technique [0002] Pogo pin is a precision connector used in electronic products such as mobile phones, and is widely used in semiconductor equipment for connection. [0003] Pogo pin is a spring-type probe formed by riveting and pre-pressing the three basic parts of needle shaft, spring and needle tube through precision instruments. There is a precise spring structure inside. The surface coating of the pogo pin is generally gold-plated, which can better improve its anti-corrosion function, mechanical properties, electrical properties, etc. Needle points include pointed needles, grasping needles, round needles, knife-shaped needles, etc. Pogo pins are generally used in precision connections in electronic products such as mobile phones, communications, automobiles, medical, aerospace, etc., which can improve the corrosion resistanc...

Problems solved by technology

However, in the needle mold provided by this patent, the needle plate (3) is formed by superimposing the upper needle plate 31, the base plate 32 and the lower needle plate 33. This three-layer structure is difficult to fix during processing, and the gap between the plates is easy. Misalignment occurs, and the processing error is difficult to control, which reduces the subsequent assembly accuracy of the probe and lowers the assembly efficiency.
