Earth terminal for flexible conductors with metal braid

Abstract

The invention discloses a grounding terminal for a flexible conductor with a metal mesh grid. The grounding terminal comprises a metal saddle and a grounded metal support, the metal saddle comprises asaddle body in the middle, and the saddle body extends towards two sides to form saddle side frames. The saddle side frames are fixedly connected with the metal support, a through groove through which the flexible conductor passes is formed between the saddle body and the metal support, and the flexible conductor is vertical to the metal saddle. The metal saddle is also provided with a limiting piece for limiting the flexible conductor, the limiting piece makes contact with the metal mesh grid and is grounded through the metal saddle and the metal support, so that the effective and flexible contact with a system is allowed. The continuity of grounding connection is guaranteed even under the condition that a cable and the metal mesh grid of the cable deform, the firm mechanical support isfurther provided, and the cable can be prevented from being torn.

Description

technical field [0001] The invention relates to a grounding terminal, in particular to a grounding terminal for a flexible conductor with metal braided mesh. Background technique [0002] Grounding of electrical installations is a common requirement in most domestic and industrial circuits. Especially in the case of heating cables used in power heat tracing, their production and installation are governed by the IEC 62395-1 and IEC 62395-1-2 standards. [0003] Electrical standards, such as standard N60335-1, state in its clause 28.2: Electrical connections and connections to ensure grounding continuity must be made in such a way that contact pressure is not transmitted through insulating materials that are prone to adsorption or deformation , unless removal or deformation of the insulating material is likely to be compensated by sufficient elasticity of the metal fittings. [0004] Some electrical junction boxes for cable connections include a metal braid which must be gro...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the disadvantages of the prior art by providing an earth terminal for flexible conductors with metal braid which allows an effective and flexible contact system even in the event of deformation of the cable and its metal braid down, also guarantees the continuity of the ground connection
