Abstract

The present invention relates to a sealing connector of an explosion-proof multicore cable, and more particularly, a housing in which a multicore cable (2) is inserted therein and a separate front and rear housing (110, 120) for filling and sealing a compound filler. Providing the 100, the front and rear housing is formed by the recess 130 to the inner coupling portion so that the compound filler is inserted into the connector in the inserted filled state so as to prevent the separation from before and after after solidification, through the cable during an electrical fire accident As well as blocking the transmission of flames, it is possible to reuse and recycle the connector only by replacing the housing, thereby providing excellent economy and efficiency.

Description

Explosion-proof multicore cable sealing connector {EXPLOSION-PROOF TYPE CABLE GLAND}

The present invention relates to a sealing connector of explosion-proof multi-core cable, and more specifically, compound filler filled inside the connector for explosion-proof function is packed into a separate housing to be assembled and reused by replacing only the housing. TECHNICAL FIELD The present invention relates to a sealing connector of an explosion-proof multicore cable that provides excellent economy and workability.

In general, various electrical fire accidents occur due to partial arc discharge, overheating, sparks, etc. in cables connecting electrical devices.

If the flames or sparks from these electrical fire accidents are transmitted through cables, they cause more serious problems because they provide a secondary fire source for electrical equipment or other equipment.

In order to prevent such a conventional problem, that is, flames or sparks generated at the time of an electrical fire accident of the cable is transmitted through the cable and spread to the secondary fire accident, the sealing process of various structures is performed by sealing connectors of various structures at certain positions of the cable. It was to block the transmission of flames or sparks due to fire accidents.

In more detail, the multi-core cable is inserted into the connector body, and the cable is inserted and mounted to be spaced apart from each other by the shade, and the sealing process is performed to block the front and rear directions by inserting and filling concrete or compound inside. Shut off the transmission of flames or sparks due to electric fire accidents.

However, since the conventional sealing connector inserts and fills concrete or compound directly into the body, the connector and the concrete or compound are integrally coupled to each other so that it is difficult to replace or reuse the connector. There was a problem.

The present invention has been made to fundamentally solve the problems of the prior art and the technology previously filed by the applicant, the compound filler filled in the connector for explosion-proof function in a separate housing with a multi-core cable It is the purpose to provide excellent economy and efficiency by filling and assembling to prevent the transmission of flame through the cable in the event of an electrical fire, as well as to reuse and recycle by replacing only the housing.

This invention is

Insert a compound filler with a multicore cable inside to seal;

The multi-core cable is achieved by inserting the compound filler in a housing provided separately and inserting it inside the connector in a sealed state to block the front and rear.

The present invention is composed of the front housing and the rear housing coupled to the rear end of the front housing to form a stepped portion, the front and rear of the housing to form a recessed portion to form a compound so that the compound filler is prevented from falling back and forth It is characterized by the configuration to be sealed.

The present invention inserts the compound filler filled inside the connector for explosion-proof function into a structure that prevents the front and back of the separation in the separate housing to be assembled and installed inside the connector, so when the electric fire accident due to partial arc discharge, overheating, explosion of the cable It prevents secondary fire accidents by blocking the transmission of flames through the cable, and it is possible to reuse and recycle the connector only by replacing the housing, and to keep the service life long by preventing the compound filler from separating and detaching back and forth during use. Therefore, it has the effect of providing excellent economics and efficiency.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

First, as shown in Figures 1 to 4, the explosion-proof multi-core cable sealing connector, the main body 11 and the sealing bushing 12 is coupled to each other by a nut 13 at the outer periphery, the sealing bushing Grand body (15) and the fitting (16) to the (12) to form a connector 10 by mutually coupling with the nut (17) on the outer periphery,

The connector 10 is configured to seal the front and rear by inserting a compound filler into the sealing bushing 12 together with the shade 18 for guiding the multicore cables 2 spaced apart from each other.

At this time, the present invention has a separate housing 100 having an inner through hole 150 into which the multicore cable 2 is inserted to insert the compound filler 5 together with the multicore cable 2 in the housing. It is characterized by inserting into the interior of the sealing member 12 in a sealed state to block the front and rear.

That is, the compound filler 5 is not directly filled in the connector 10, but is filled in a separate housing 100 to be inserted into the connector 10 in a sealed state to install the housing 100. To achieve.

In this case, the housing 100 includes a front housing 110 forming a stepped portion 115 corresponding to the stepped portion 12 ′ of the sealing member 12, and a rear housing 120 coupled to the rear end of the front housing. It is configured to), the inner coupling portion of the front and rear housing 110, 120 is formed to form a recess 130 so that the compound filler 5 is sealed to prevent the front and rear departure.

In addition, the structure of the front and rear housings 110 and 120 can be variously changed, as well as any structure that can be sealed by filling the compound filler 5 therein belongs to the scope of the present invention. To reveal.

As an unexplained reference, 121 and 122 are formed before and after the rear housing 120 to indicate the stepped portion for coupling the front housing 110 and the grand body 15.

Next will be a look at the operation and action of the subject innovation configured as described above.

The sealing connector of the present invention is intended to prevent the transfer of flame through the cable in the event of an electrical fire due to partial arc discharge, overheating, sparking, etc., to the cable connecting the electrical device.

To this end, the present invention provides a separate housing 100 and inserts and fills the compound filler 5 together with the multicore cable 2 into the inner through hole 150 of the housing to seal the front and rear to block the front and rear. It is inserted into the sealing bushing 12 of the connector 10.

In other words, the transmission of the flame through the multicore cable 5 is blocked by the compound filler 5 sealed in the housing 100.

Furthermore, the present invention is not filled directly with the compound filler 5 in the connector 10 as in the prior art, but is filled and installed using a separate housing 100 so that the sealing process is reused by replacing only the housing 100. And recycling is possible to maximize the economics.

In addition, the present invention is configured to couple the housing 100 to the front, rear housing 110, 120, the front housing is a step portion 115 corresponding to the step portion 12 'of the sealing member 12 And the rear housing is formed to protrude inward from the rear of the front housing inward to form a recess 130 in the inner coupling portion of the front and rear housings 110 and 120.

Therefore, since the compound filler 5 is filled in the recess 130 of the front and rear housings 110 and 120 together with the through hole 150, the compound filler 5 is solidified in the recess 130. Since the corresponding protrusions are formed, the compound fillers can be effectively prevented from being separated, separated from each other in the front-rear direction or causing a gap during use, thereby effectively using the sealing function for a long time.
