Description

Technical Field

[0001] The utility model relates to the technical field of relay protection, in particular to a relay protection auxiliary device. Background Art

[0002] A relay, also known as an electric relay, is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is usually used in automatic control circuits. In fact, it is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] The existing relay protection auxiliary device is protected by an external frame during use. If it is a fully enclosed type, the heat dissipation is slow, and it is easy to be contaminated with dust and inconvenient to disassemble. At the same time, the internal wiring harness needs to be sorted, but some mounting frames cannot adapt to wiring harnesses of different thicknesses. If the wiring harness is too thick, it is easy to cause damage to the surface. In any case, if the wiring harness is too thin, it cannot be firmly clamped. For this reason, we propose a relay protection auxiliary device. Utility Model Content
