Abstract

The utility model relates to a high voltage cable connection device, in particular to a high voltage cable connector applicable to coal mines. The utility model resolves the problem of no quarantine connection quality of high voltage cable connection device connecting high cable prior used in coal mine, and the utility model comprises a tube body, a loudspeaker fixed on both sides of the tube body. The tube body is internally provided with two round-cake shape insulation supports in accordance with the tube body inner wall. The round-cake shape insulation supports have three equal through holes, and the wall of the tube body has a cable glue casting mouth; the loudspeaker has a gap with a fixed thread pressed board trough bolt. The utility model has the advantages of reasonable structure, convenient operation, good use effect and high reliability, thus the utility model satisfies the needs of high voltage cable connection in coal mines.

Description

High-voltage cable connector

Technical field

The utility model relates to a kind of high-tension cable jockey, is specially a kind of high-voltage cable connector that is applicable under the coal mine.

Background technology

The high-voltage cable connector that uses under the coal mine generally adopts direct connected mode of pyrocondensation and bolt-type fast-assembling connected mode at present, and preceding a kind of connection request height is not easy to operate, does not often reach requirement because of connecting, and causes cable explosive; The back is a kind of often causes insulation to reduce because of the latch loose contact makes it local overheating, easily makes cable grounding and short circuit; In a word, can not absolutely guarantee the reliable use of high-tension cable in the down-hole.

Summary of the invention

The utility model connects the problem that the high-tension cable quality of connection can't ensure in order to solve the existing high-tension cable jockey that is used under the coal mine, and a kind of high-voltage cable connector is provided.

The utility model is to adopt following technical scheme to realize: high-voltage cable connector, the loudspeaker that comprise cylindrical shell, are fixed in the cylindrical shell two ends are chewed, being provided with the two round pie insulation consistent with cylinder inboard wall in the cylindrical shell supports, (promptly three through holes are opened on same circumference evenly to have three through holes in the round pie insulation support, and alternate 120 degree), have the cable gum sprue gate on the barrel of cylindrical shell; Loudspeaker are chewed and are had breach, and indentation, there is by bolt live conductor plate.

For the ease of installation, convenient disassembly, described cylindrical shell is made of intermediate cylinder that has the cable gum sprue gate and the connector that is fixed in the intermediate cylinder two ends.In order to make this connector can be applicable to the wet environment of down-hole, the spark of avoiding the blast of cable joint place to be produced simultaneously spills, and cause fire damp blast, be provided with the O RunddichtringO between intermediate cylinder and the connector, loudspeaker chew and connector between be provided with quoit and sealing ring.

Consider dissimilar (as: armoured cable, the quads) of cable simultaneously,, reach purpose easy and simple to handle, be respectively equipped with the ground connection ear on the inside and outside wall of connector for making things convenient for ground connection.The cable gum sprue gate is furnished with Explosion-proof cap.

During stube cable, at first successively loudspeaker are chewed, quoit, sealing ring, connector is placed on the two high-tension cable lines that need to connect, then the three-phase heart yearn of a cable is wherein passed three through holes that two insulation are supported in the cylindrical shell respectively, the three-phase heart yearn of two high-tension cables of needs connection is connected with copper connecting leg or aluminium connecting leg, and compress with oil pressure pincers, be dragged in the cylindrical shell after pressing, make the junction just in time between two insulation are supported, connect good interior ground connection or external ground, with cylindrical shell, connector, interfix by bolt between loudspeaker are chewed, cable is compressed then with the cable tension, and with the tension disc at the loudspeaker place of chewing, at this moment, threephase cable spacing in the cylindrical shell equates, after the cable gum sprue gate pours into cable gum in cylindrical shell, treats to compress after cable gum cools off the Explosion-proof cap at sprue gate, so far, connection is finished.

Compared with prior art, the utility model in cylindrical shell, be provided with two on it all portion have the insulation of three through holes to support, the threephase cable heart yearn kept at a certain distance away support, and in cylindrical shell, pour into cable gum, avoided being short-circuited between heart yearn, satisfied the insulating requirements that cable connects largely; Multiple hermetically-sealed construction setting has avoided moisture to enter in the cylindrical shell, also avoids preventing the appearance of high-voltage earthing and short-circuit state and fire damp blast situation because the Mars that the cable blast produces spills.

The utility model is rational in infrastructure, and is easy to operate, and result of use is good, satisfied the requirement that under the coal mine high-tension cable is connected, the reliability height.
