Abstract

The invention discloses a communication joint among hydraulic support controller shelves, comprising a connector assembly which is arranged in a tubular joint and is positioned by a locating pin. A pouring sealant is arranged in the cavity body of the intake end of the connector assembly in the tubular joint, and the tubular joint is in sealing and fixed connection with the connector assembly by the pouring sealant. Sealing rings are respectively arranged between the tubular joint and the connector assembly and on the peripheral surface of the tubular joint. The inner part of the tubular joint is provided with a fixed hole slot in the position near a jack, and the tubular joint is provided with a locating hole and a locating pin arranged in the locating hole. The communication joint has the advantages that the communication joint plays a role of resisting moisture, dust, corrosion and shock and increases the use performance of the connector assembly; the corresponding position of the locating pin is provided with the locating hole and the locating pin arranged in the locating hole, which is used for distributing right and left joints and avoids the faulty installation in using.

Description

technical field [0001] The present invention relates to a communication joint, in particular to a hydraulic support controller inter-frame communication joint. Background technique [0002] The underground environment of the mine is humid, and ordinary communication connectors are easily invaded by water vapor and damp, so that the contact terminals inside the connector are corroded, resulting in poor signal transmission quality; and when the communication connector is used for the inter-frame communication connection of the hydraulic support controller Need to have a certain anti-vibration performance and explosion-proof function. Contents of the invention [0003] The object of the present invention is to provide a moisture-proof and vibration-proof hydraulic support controller inter-rack communication joint. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] The inter-frame communication joint of the hydrau...
