Pogo pin assembly with double-tube assembly structure

Abstract

The invention relates to the technical field of electronic products, in particular to a Pogopin assembly of a double-tube assembly structure, which comprises an outer needle tube, an inner needle tube, an inner needle head, a spring and an outer needle head, a containing cavity is formed in the outer needle tube, a first opening communicated with the containing cavity is formed in a first end of the outer needle tube, and a sealing baffle used for closing the containing cavity is arranged at a second end of the outer needle tube. The inner needle tube is arranged in the containing cavity in a penetrating mode through the first opening, the outer wall of the inner needle tube is in interference fit with the inner wall of the outer needle tube, the sum of the wall thickness of the inner needle tube and the wall thickness of the outer needle tube is 0.35 mm, the first end of the inner needle tube is in limiting fit with the first end of the outer needle tube, and the second end of the inner needle tube abuts against the sealing baffle in a matched mode. The first end of the inner needle tube is provided with a second opening communicated with the penetrating hole, the inner needle and the spring are arranged in the penetrating hole, the first end of the spring abuts against the second end of the inner needle in a matched mode, the second end of the spring abuts against the sealing baffle, the second end of the outer needle is limited in the penetrating hole and abuts against the first end of the inner needle, and the first end of the outer needle penetrates out of the penetrating hole through the second opening.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a Pogopin assembly with a double-tube assembly structure. Background technique [0002] For Pogopin components applied to 25A high-current electronic cigarette products, the shape of electronic cigarettes needs to be smaller and smaller. For conventional Pogopin production process design (current below 10A, wall thickness below 0.20mm), the product size will be larger and the wall thickness is thicker. Thick, it is not suitable for assembly, and the conductive cross-sectional area of ​​the needle tube is insufficient. SUMMARY OF THE INVENTION [0003] In view of the defects of the prior art, the present invention provides a Pogopin assembly with a double-tube assembly structure, which effectively solves the deficiencies of the prior art. [0004] In order to achieve the above object, the technical scheme applied by the present invention is as follows: [0005] A P...
