Abstract

The invention discloses a low-pressure cable sealing device and a manufacturing method thereof, wherein the sealing device includes a sealing sleeve body and a cable. The annular space between the cable and the inner cavity wall of the sealing sleeve is filled with sealant, and at least one of the left and right ends of the sealing sleeve body is provided with a sealing fit portion for axially connecting with the interface of the low-pressure box. The sealing device is axially butted on the low-pressure box, and the sealing fitting portion of the sealing sleeve body is used to seal and cooperate with the interface of the low-pressure box. The information exchange between the test piece and the detection equipment during the low-pressure test is realized. The method is simple and easy to operate, with good sealing effect and reliable connection.

Description

technical field [0001] The invention relates to a low air pressure cable sealing device and a manufacturing method thereof. Background technique [0002] When the low-pressure test box is doing air pressure test, it is often necessary to energize the inside of the test box or connect the testing equipment. At this time, it is necessary to solve the sealing problem of the cable connected to the test box; the cable sealing device is to solve the problem from the outside (atmospheric pressure environment) to the test. Sealing issues with wires passing inside the box (below atmospheric pressure). Most of the traditional methods are sealed by media such as plasticine or wood boards, which cannot achieve a good sealing effect. Contents of the invention [0003] The purpose of the present invention is to provide a low-pressure cable sealing device manufacturing method to solve the technical problem that the existing sealing method has poor sealing effect on cables. At the same ...
