Damp-proof heavy-load connector

Abstract

The utility model relates to a moistureproof heavy load connector comprising a receiving main body, two sides of the external part of the receiving main body are fixedly connected with limiting blocks, one sides of the external parts of the two limiting blocks are respectively and rotatably connected with a first sealing plate and a second sealing plate, and the inner walls of the first sealing plate and the second sealing plate are fixedly connected with sealing gaskets. A fixing block is fixedly connected to one side of the top of the second sealing plate, and an inserting block is fixedly connected to the top of the fixing block. The beneficial effects of the utility model lie in that although a heavy-load connector in the prior art can be fixed on different types of installation guide rails through an arranged fixing mechanism, the installation efficiency is improved, but when the heavy-load connector is used in a relatively humid environment, if the heavy-load connector is not subjected to moisture-proof treatment, the heavy-load connector cannot be fixed on the installation guide rails. The problems that the device is affected with damp and even damaged due to the fact that wet gas easily permeates into the connector, the service life is shortened, and the use danger is improved are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of heavy-duty connectors, in particular to a moisture-proof heavy-duty connector. Background Art

[0002] Heavy-duty connectors are one of the indispensable devices in construction machinery, textile machinery and other workplaces. Heavy-duty connectors are devices used to connect and protect pipelines. Heavy-duty connectors have the advantages of pre-installation, pre-wiring, preventing mis-insertion, and improving work efficiency. They can provide effective protection in harsh environments.

[0003] After searching, a Chinese patent discloses a heavy-duty connector with high conductivity (authorization announcement number CN 210040749U). The patented technology includes a heavy-duty connector body, a protective mechanism and a fixing mechanism. The heavy-duty connector body includes a first connecting block, a handle, a second connecting block and a base. The protective mechanism includes a button, which is located on one side of the handle. A slide groove is provided on one side of the handle. Limiting grooves A are provided on both sides of one end of the slide groove. One end of the button is fixedly connected to a limiting ring B, and both ends of one side of the limiting ring B are fixedly connected to a spring B. By adding a protective mechanism on one side of the handle, abnormal loosening and falling of the heavy-duty connector caused by accidentally touching the handle is avoided, the normal operation of the electrical equipment is guaranteed, and the service life of the electrical equipment is effectively improved. By adding a fixing structure at the bottom of the base, the heavy-duty connector body can be fixed on installation rails of different models, which improves the installation efficiency of the staff and also facilitates the disassembly of the heavy-duty connector body.

[0004] In the actual application process of this patented technology, although the heavy-load connector can be fixed on different types of mounting rails through the setting of the fixing mechanism to improve the installation efficiency, when the heavy-load connector is used in a relatively humid environment, if it is not treated with moisture-proof, it is easy for humid gas to penetrate into the interior of the connector, causing the device to get damp or even damaged, thereby reducing the service life and increasing the risk of use.
