Cable gland and electric device

Abstract

The invention discloses a cable gland comprising an inner fitting and a cable seal ring. The cable seal ring comprises a cylindrical mounting part and a seal bottom plate. The seal bottom plate is fixedly connected to the cylindrical mounting part. The seal bottom plate is disposed at the first end of the cylindrical mounting part. The inner fitting comprises a cylindrical body and a claw. The body comprises a first sleeve and a second sleeve, wherein the sleeves are serially connected with each other and fixedly connected with each other. The claw is fixed to the end face of the first sleeve through the end of the claw. The inside diameter of the first sleeve is larger than that of the second sleeve. The cylindrical mounting part is inserted into the first sleeve through the second end of the cylindrical mounting part, and the part from the inner wall of the first sleeve to that of the cylindrical mounting part is gentle. The cable gland has the advantages that smoothness of a cable passage can be ensured, the cable is prevented from excessively pulling the cable seal ring, shedding of the cable seal ring is prevented, the cable seal ring and the inner fitting can be fitted reliably, and using is facilitated for users. The invention further discloses an electric device using the cable gland. The electric device is convenient for users to use.

Description

technical field [0001] The invention relates to the technical field of machinery industry, more specifically, to a cable fixing head, and also to an electrical device. Background technique [0002] Cable glands are devices used to fix and protect cables in various electrical equipment. [0003] The existing cable fixing head includes a cable sealing ring and an inner fitting, wherein the cable sealing ring includes a cylindrical mounting part and a sealing bottom plate fixed at one end of the cylindrical mounting part; the sealing bottom plate is provided with a cable through hole; The shaped mounting part is inserted into the inner fitting. In application, the above-mentioned cable fixing head is arranged on the shell of the electrical equipment, and the external cables of the electrical equipment penetrate into the interior parts, and penetrate into the installation part, and then pass through the cable through holes of the sealed bottom plate to reach the shell of the el...

Problems solved by technology

[0004] However, in the existing cable fixing head, after the installation part is inserted into the interior part, a boss will be formed inside the interior part, and the cable will be blocked by the above boss during use, causing the cable to pull the boss of the cable sealing ring excessively, thus causing the cable The sealing ring falls off, which is not convenient for users to use

[0005] In addition, there are cable through-holes on the sealing bottom plate of the above-mentioned cable sealing ring, but the multiple cables of the same electrical equipment are of different sizes, and the cables of different electrical equipment are of different sizes. It often happens that the cables and the cable through-holes cannot be tightly matched, resulting Poor sealing of cable glands
