Problems solved by technology

Although the use of this invention can ensure a stable and low connection between a pair of contact points of the foot and the concave contact, but because it does not limit the width of the curved portion of the elastic portion, the curved portion used for conduction may have a small area. Causes technical problems of high probe impedance and poor conductivity

Abstract

The invention discloses a crimping elastic piece of a single buffer channel. The crimping elastic sheet includes a first metal adapter portion, a second metal adapter portion and a metal bending portion; the first metal adapter portion, the second metal adapter portion and the metal bending portion are integrally formed; the first metal adapter portion and the second metal adapter portion have probe heads; the metal bending portion is composed of two metal conductive strips arranged in parallel and spaced from each other; each metal conductive strip is made of a material that is both electrically conductive and elastically deformable; the width of the probe heads / 4 <= the width of each metal conductive strip <= the width of the probe heads / 3. The invention is simple in structure and is convenient to use; the area of the metal bending portion for conduction is effectively increased by designing the width of the metal bending portion to be 2 to 4 times the width of the probe heads and designing the metal bending portion into the two parallel metal conductive strips spaced from each other; the impedance and continuity of the elastic sheet probe can be improved.

Description

technical field [0001] The invention relates to a crimping shrapnel, which belongs to the technical field of testing non-standard products such as electronic screens, and in particular to a crimping shrapnel with a single buffer channel. Background technique [0002] In the prior art, most of the conduction devices on the test fixture are pogo pin connectors. The pogo pin connector is formed by riveting the three basic components of the needle shaft, spring, and needle tube through precision instruments. Because the pogo pin The needle shaft of the connector is relatively thin and the aperture of the needle tube used to install the needle shaft is small, so the spring thimble connector has technical problems such as difficult processing and difficult control of processing accuracy. In order to solve the above technical problems, the Chinese utility model patent CN206515372U discloses a flat probe for integrated circuit testing, which includes an upper contact end, a bent sec...
