Abstract

The invention discloses a radio frequency / microwave sliding electrical contact structure based on a shrapnel array, comprising: a source conductor, a target conductor, a screw, a conductive shrapnel, and a supporting shrapnel, and the conductive shrapnel can make a reciprocating straight line along the surface of the target conductor together with the source conductor Movement, the present invention adopts the technical route of distinguishing the conductive function of the shrapnel from the supporting function, and designs the conductive shrapnel and the supporting shrapnel respectively, and can select the optimal material that can satisfy its function according to the function, and place the most easily damaged and invalid supporting shrapnel in the ring It is divided into multiple identical structural units upwards, which significantly reduces the difficulty of assembly and improves the maintainability of components. The source conductor and target conductor with active water cooling structure are used to control the electrical contact temperature. The invention is especially suitable for high vacuum, Sliding electrical contact applications under high current loads.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a radio frequency / microwave sliding electrical contact structure based on shrapnel arrays, which is especially suitable for applications under high temperature, high vacuum and high current-carrying conditions. Background technique [0002] Electrical contact is a common component on electrical and electronic equipment, the purpose is to realize the electrical connection between two components. According to the relative movement state between the electrical contact parts, electrical contact can be divided into static electrical contact and dynamic electrical contact. Sliding electrical contacts are a common type of dynamic electrical contact, where there is relative linear motion between two electrically connected parts. Common sliding electrical contacts in civilian use mainly include motor brushes, pantograph slides on electric locomotives, etc. The above-mentioned slidin...
