EMC Cable Glands

Abstract

The invention discloses an electromagnetically compatible cable locking joint, which solves the problems of inconvenient connection between the existing cable joint and the cable wire and poor shielding effect, and comprises a joint main body, a joint cap, a sealing ring and a shielding member; the joint The main body has a central hole, and there is an inner step in the central hole; the sealing ring is connected to the end of the joint main body, and a positioning groove is formed between the sealing ring and the inner step; the joint cap is connected to the sealing ring; the The shield includes an upper ring, a lower ring and arc-shaped shrapnels. The arc-shaped shrapnels have multiple pieces and are evenly arranged around the circumference. The upper end of each arc-shaped shrapnel is formed on the upper ring, the lower end is formed on the lower ring, and the arc-shaped shrapnel The middle part of the middle part is bent towards the center of the upper ring or the lower ring, the shielding part is arranged in the central hole, and the upper ring is located in the positioning groove, and the lower ring can move along the axial direction of the central hole. Convenient and good shielding effect.

Description

technical field [0001] The invention relates to an electromagnetic compatibility type cable locking joint. Background technique [0002] Nowadays, EMC cable locking joints are widely used. The cable shielding layer and the junction box are connected through the EMC cable joint, so that electronic equipment neither interferes with other equipment nor is it affected by other equipment. Its main function is to connect and fix cables, while ensuring its high-required waterproof performance, flame-retardant performance and electromagnetic compatibility function, so as to effectively form long-term stable and effective protection for cables and equipment. [0003] In the prior art, the structure of the EMC cable locking joint includes a metal body, a metal joint cap, nylon claws and a ring-shaped shielding ring. When the EMC cable locking connector is connected to the cable, insert the cable with the shielding layer removed into the connector, place the shielding ring between the...
