Problems solved by technology

However, it has been found that there are reliability problems in this installation structure. For example, when the upper cover is subjected to a strong impact, due to the effect of inertia, there may be a quality accident in which the buckle structure of the shrapnel is loose.

Embodiment Construction

[0024] In view of the defect that the installation structure of the overload protector in the prior art is easy to loosen, the present invention believes that when the overload protector is pressed down by force, the force that the existing shrapnel anti-buckling structure can bear is relatively small, so there is a possibility of loosening. hidden danger.

[0025] To this end, the present invention provides a new installation structure for overload protectors (such as three-phase compressor overload protectors), such as Figure 1-3 shown.

[0026] Specifically, the installation structure of the overload protector of the present invention mainly includes an overload protector housing 1 and an overload protector bracket 2 . Among them, the overload protector 3 is fixed in the overload protector housing 1, the overload protector housing 1 is installed together with the overload protector bracket 2, and the overload protector bracket 2 is fixed on the installation part such as t...

Abstract

The invention discloses an overload protector mounting structure. The overload protector mounting structure comprises an overload protector outer shell and overload protector supports, wherein each overload protector support is provided with clamping-mounting portions, buckle structures are arranged at the tail ends of the clamping-mounting portions and protrude in the width directions of the clamping-mounting portions, and the overload protector outer shell is provided with clamping-connection portions matched with the clamping-mounting portions. The overload protector mounting structure is high in reliability, it can be guaranteed that an overload protector and the supports are not loosened or separated even under intense impact, and meanwhile the cost is low. The invention further discloses the overload protector supports.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an installation structure of an overload protector. Background technique [0002] The overload protector is an important safety protection device in the compressor, for example, it is used to automatically disconnect the power supply when the compressor current exceeds the limit or the temperature exceeds the limit. In the prior art, the overload protector of a three-phase compressor usually fixes the overload protector on the compressor upper cover by means of the shrapnel reversed, that is, the overload protector is fixed by a hook-shaped structure formed by bending the shrapnel. However, it has been found that this installation structure has reliability problems. For example, when the upper cover is subjected to a strong impact, due to the effect of inertia, a quality accident that the shrapnel anti-buckling structure is loosened may occur. [0003] Therefore, it is an ur...
