Embodiment 1

[0018] This embodiment provides a retractable pin, such as figure 1 As shown, it includes: a fixed cylinder 1 and a telescopic pin 2, wherein the telescopic pin 2 is socketed with the fixed cylinder 1, and the fixed cylinder 1 is welded on the board. The contact surface between the fixed cylinder 1 and the telescopic pin 2 is provided with an anti-pull-off buckle 3 to prevent the telescopic pin 2 from being pulled off from the fixed cylinder 1 . The fixed cylinder 1 is provided with a plurality of positioning grooves 4, and the telescopic pins 2 are provided with elastic positioning protrusions matching the positioning grooves 4, so that the length of the telescopic pins can be adjusted, and the length of the telescopic pins is avoided Change by mistake.

Abstract

The invention provides a telescopic pin which comprises a fixing cylinder and a telescopic pin body. The telescopic pin body is connected with the fixing cylinder in a sleeved mode, and the fixing cylinder is welded to a board card. According to the invention, the tinning rate of a connector is improved, so that the welding firmness is ensured, the connection universality is improved, the use of acustomized connector is reduced, the material purchasing cost is saved, the design change caused by too long or too short pins of the connector in research and development is reduced, and the research and development design cost is reduced. According to the telescopic pin, the design change caused by too long or too short connector pins in research and development is reduced, and the research anddevelopment design cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a retractable pin. Background technique [0002] The PIN pin of the existing connector is usually welded with a separate welding post, but this will cause the welding post to be too short to be welded, or because the surface mount material is too long, the scraper cannot be used when tinning the surface mount material, so the factory cannot perform surface mount. Tinning of materials. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a retractable pin to solve the above-mentioned technical problems. [0004] The present invention provides a retractable pin, comprising: a fixed cylinder and a telescopic pin, the telescopic pin is socketed with the fixed cylinder, and the fixed cylinder is welded on a board. [0005] Further, the contact surface between the fixed cylinder and the telescopic pin ...
