Large-caliber split type conductive slip ring suitable for high-humidity environment

Abstract

The invention discloses a large-caliber split type conductive slip ring suitable for a high-humidity environment, which is composed of a center shaft, a combined support, ring pieces, insulating spacers, a pressing plate and an electric brush assembly. The insulating spacer is a stepped spacer which is made of POM (polyoxymethylene) and is high in inside and low in outside, and a wire passing notch is milled in the inner ring of the insulating spacer. The ring piece sleeves the outer circle of the protruding portion of the insulating spacer, and the wire passing notches of two adjacent insulating spacers are staggered by 180 degrees. The creep distance and the gap between the stator and the rotor are ensured through the design of the conductive slip ring structure to control and prevent moisture diffusion, and a high insulation resistance value between rings in a high-humidity environment is used, thereby ensuring integrity and stability of transmitted signals. The application of the large-caliber split type conductive slip ring in a high-humidity environment is realized, great convenience is provided for the field of electric rotation signal transmission, and the problems of integrity and stability of signals transmitted by the large-caliber split type conductive slip ring in a 360-degree rotation mode in the high-humidity environment are solved.

Description

technical field [0001] The invention relates to the technical field of conductive slip ring signal transmission, in particular to a large-diameter split conductive slip ring suitable for signal and power transmission in a high-humidity environment. Background technique [0002] Conductive slip ring belongs to the application category of electrical contact sliding connection. A precision power transmission device for image, data signal and power transmission of a relative rotating mechanism. It is especially suitable for applications where unlimited continuous rotation is required, and at the same time power or data needs to be transmitted from a fixed position to a rotating position. [0003] Conventional conductive slip rings that work in high-humidity environments are integrated slip rings. Generally, the ring body is sealed to ensure the reliability of work in high-humidity environments. However, because the split type slip ring cannot achieve external sealing, it is ea...

Problems solved by technology

However, because the split type slip ring cannot achieve external sealing, it is easy to cause the insulation resistance between the rings to drop in a high-humidity environment, which will cause signal interference between the rings; if it is serious, it will cause a short circuit between the rings, which will seriously distort the signal and cause the overall failure. machine failure
