Description

Technical Field

[0001] The invention relates to the technical field of insulating terminals, and in particular to an insulating terminal for a high-voltage conductive slip ring. Background Art

[0002] Conductive slip ring is a rotating electrical transmission connector that realizes signal and power transmission between two rotating parts. The sliding transmission in the rotating state is realized through sliding electrical friction contact between the stator part and the rotor part of the slip ring.

[0003] During the use of conductive slip rings under special working conditions of high voltage, insulation design is required between conductors and between conductors and the ground. At the same time, it is necessary to isolate the excess materials produced by wear of the conductive slip rings after long-term rotation to avoid discharge and breakdown caused by insufficient insulation strength. Insulation isolation is usually achieved through insulating sheets or special insulating terminals. The purpose is to isolate the conductive channel and prevent short-circuit burning during the conduction of the slip ring. How to improve the withstand voltage insulation has become a technical problem that needs to be solved.

[0004] Ordinary insulating terminals have a normal creepage distance and are often not designed with special wear residue storage grooves. There are also problems with improper material selection, which leads to a low upper voltage resistance limit for the slip ring. At the same time, there is accumulation of wear residues, low working voltage resistance safety, and insufficient product reliability. Summary of the invention

[0005] In view of the above technical problems, the present invention proposes an insulating terminal for a high-voltage conductive slip ring, wherein multiple groups of insulating bosses are arranged on both sides of the insulating terminal, and the insulating bosses on both sides are symmetrically distributed about the center line of the insulating terminal, and rotating flanges for connecting conductors are installed at both ends of the insulating terminal, and multiple groups of chip grooves are arranged on both sides of the insulating terminal, and the chip grooves on both sides are symmetrically distributed about the center line of the insulating terminal.

[0006] Furthermore, a butt thread for connecting with a conductor is provided at the center of each rotating flange.

[0007] Furthermore, each of the chip storage grooves is provided with two "V"-shaped grooves, the cross-section of the chip storage groove is sawtooth-shaped, the groove depth of each "V"-shaped groove is 1mm, and the groove width of each "V"-shaped groove is 1mm.

[0008] Furthermore, the insulating terminal is made of epoxy resin plus glass fiber material.

[0009] Compared with the prior art, the present invention has the following beneficial effects: (1) Since the insulating terminal of the present invention is provided with a plurality of insulating bosses, the creepage distance of adjacent conductors isolated by the insulating terminal is increased, and the safety margin during high-voltage point operation is greatly improved. At the same time, since a plurality of "V-shaped" chip grooves are provided, the cross-section of the chip groove presents a sawtooth shape with high and low inclinations, so that the wear and tear debris that falls off the conductive slip ring and enters the insulating terminal can enter the "V-shaped" chip groove for storing chips; (2) The insulating terminal of the present invention has the advantages of simple structural design, safe and reliable operation, and easy production and promotion.

[0014] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0015] Example: Figure 1-Figure 3 An insulating terminal for a high-voltage conductive slip ring is shown, wherein a plurality of insulating bosses 1 are arranged on both sides of the insulating terminal, and the insulating bosses 1 on both sides are symmetrically distributed about the center line of the insulating terminal, and a rotating flange 3 for connecting a conductor 5 is installed at both ends of the insulating terminal, and a plurality of chip grooves 2 are arranged on both sides of the insulating terminal, and the chip grooves 2 on both sides are symmetrically distributed about the center line of the insulating terminal.

[0016] A butt thread 4 for connecting with the conductor 5 is arranged at the center of each rotating flange 3 .

[0017] Each of the chip storage grooves 2 is provided with two "V"-shaped grooves, the cross section of the chip storage groove 2 is sawtooth-shaped, the groove depth of each "V"-shaped groove is 1mm, and the groove width of each "V"-shaped groove is 1mm.

[0018] The insulating terminal is made of epoxy resin plus glass fiber material.

[0019] The working principle of the present invention is: When the insulating terminal needs to be installed, the rotating flange 3 is docked with the adjacent conductor 5 under the action of the docking thread 4 by rotating the flange 3, so that the rotating flange 3 and the conductor 5 are tightened to ensure that the rotating flange 3 and the adjacent conductor 5 are installed in place, so that the insulating terminal can safely insulate and isolate the adjacent conductor 5 when working with power.

[0020] Since the insulating terminal in the present invention is provided with a plurality of insulating bosses 1, the creepage distance of adjacent conductors 5 isolated by the insulating terminal is increased, and the safety margin is greatly improved during high-voltage point operation. At the same time, since a plurality of "V-shaped" chip grooves 2 are provided, the cross-section of the chip groove 2 presents a sawtooth shape with high and low inclinations, so that the wear and tear of the conductive slip ring that falls off and enters the insulating terminal can enter the "V-shaped" chip groove 2 for storing chips; thereby, the insulating terminal works more safely and reliably and is not prone to short circuit. The present invention has a simple structural design, low cost, and is suitable for industrial production.
