Compressor with wire protection, wire protection device and overload protector

Abstract

The invention discloses a compressor with wiring protection. The compressor comprises a compressor body, an overload protector and a wiring protection device, wherein the overload protector and the wiring protection device are arranged on the compressor body. A protective cover comprises an installation portion and a combination portion connected with the peripheral wall of the installation portion, a terminal protective cover comprises a protective cover body and a combination shade connected with the peripheral wall of the protective cover body, the installation portion is provided with a first positioning structure, a second positioning structure matched with the first positioning structure is arranged on the peripheral surface of a protector main body of the overload protector, the combination portion is provided with a first buckling structure, and the combination shade is provided with a second buckling structure buckled with the first buckling structure. The invention further provides the wiring protection device and the overload protector. By means of the wiring protection device, the overload protector can be positioned effectively, bias of the overload protector or damage to the overload protector when the overload protector is clamped into a first cavity of the protective cover is prevented, and wiring operation between a compressor terminal block and the overload protector is facilitated.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor with wiring protection, a wiring protection device and an overload protector thereof. Background technique [0002] In the field of air-conditioning manufacturing, the composition of air conditioners mainly includes: compressor, condenser, throttling device, evaporator, and auxiliary components such as stop valves. Among them, the compressor is the core component of the air conditioner, which is equivalent to the heart of the human body. In order to prevent the compressor from overloading, the general compressor is equipped with an overload protector, and the overload protector is divided into built-in and external. The overload protector is used for overcurrent and high temperature protection, so the bottom of the overload protector must be close to the top of the compressor when assembling, so as to accurately detect the surface temperature of the compressor a...

AI Technical Summary

Problems solved by technology

In this protection method, since more wires need to be connected between the terminal of the compressor and the overload protector, and the inner cavity of the protective cover is generally larger than that of the overload protector, the overload protector is easy to install when assembling the protective cover. Offset occurs or is stuck in the inner cavity of the protective cover, so that the bottom of the overload protector is not close to the top of the compressor shell, so that the compressor cannot be accurately protected, and it is easy to cause the compressor to burn out, and the existing overload The connection terminal of the protector is located at the axial end of the overload protector, and it is easy to cause damage to the connection terminal of the overload protector during assembly

In addition, the existing overload protectors are relatively large and difficult to assemble. Space for assembly needs to be reserved, which brings difficulties to the piping space.
