Large-current transmission connector structure based on spring

Abstract

The invention belongs to the technical field of large current transmission, and discloses a spring-based large current transmission connector structure, which comprises a connector plug end and a connector tail end, a plurality of binding posts are arranged on the end surface of the connector plug end, annular dovetail grooves are formed in the end surfaces of the binding posts, annular spiral springs are arranged in the dovetail grooves, and the annular spiral springs are arranged in the dovetail grooves. The spiral cross section of the annular spiral spring is oval, the spiral outer diameter of the annular spiral spring is larger than the depth of the dovetail groove, and the tail end of the connector makes contact with and extrudes the annular spiral spring to achieve large-current transmission. The annular spiral spring is used as a current transmission medium, the power supply contact pressure is kept basically unchanged through contact compression of the binding post and the end face of the tail end of the connector, the problem of compression abrasion is well solved, the reliability of a transmission link is improved, and large-current transmission is achieved.

Description

Technical field [0001] The present invention relates to the field of large current transmission technologies, and more particularly to a connector structure based on a spring-based large current transmission. Background technique [0002] With the booming technology of airborne electronic equipment integration technology, the environmental performance, spatial placement, and electrical performance of electrical connections are also increasing. Taking the airborne radar as an example, the current radar antenna array is moving rapidly toward high power, high integration, and thinning in the direction. The antenna array transmission current transmission requires up to 1000A, while the installation space is only 62mm × 62mm × 15mm (15mm 15mm) For the contact direction size). Not only that, but also need to ensure the reliability and safety of electrical connections in a harsh vibration, climate, and three anti-environment. [0003] The traditional large current transmission uses a bu...
