Problems solved by technology

[0003] However, the above-mentioned gaskets have the following problems: the use of full-density gaskets cannot ensure the tightness between the gasket and the surface of the upper case cover after installation; head
[0004] material full compact system Full foam system features Hard material, not easy to deform The material is soft and elastic advantage One-shot molding The sealing performance between the gasket and the surface of the upper shell cover is good shortcoming The seal between the gasket and the surface of the upper case cover is not good Single-layer gaskets and complex internal structures cannot be molded at one time

Embodiment 1

[0015] Such as Figure 1~2 As shown, a junction box cover gasket for fixing a thermal switch, the shape of the gasket matches the junction box cover and the contact part of the upper casing cover of the compressor, and the gasket is composed of a foaming part 1 and a compact part 2, the shape of the foaming part 1 matches the junction box cover and the contact part of the upper casing cover of the compressor, and is made of PE foam material, which has good elasticity. After the junction box cover is installed and pressed The tightness has a better effect. The foaming part 1 is provided with a mounting hole, and the compact part 2 is arranged in the mounting hole. The compact part 2 is in the shape of a boss, and its bottom is provided with a skirt 21. The upper surface of the skirt 21 is in contact with the The foaming part 1 is bonded, so that the advantages of the original two materials are combined. The dense part is formed by one-time stamping of the dense material EPDM, ...

Abstract

The invention relates to a junction box cover gasket for fixing a thermal switch, the shape of the gasket matches the contact part between the junction box cover and the upper shell cover of a compressor, and the gasket is composed of a foamed part and a compact part , the shape of the foaming part is matched with the junction box cover and the contact part of the compressor upper shell cover, and a mounting hole is provided on the foaming part, and the dense part is arranged in the mounting hole, and the compressor upper shell The thermal switch on the cover is installed on the compact part. Compared with the prior art, the invention has the advantages of simple manufacture, good sealing performance and the like.

Description

technical field [0001] The invention relates to a gasket, in particular to a junction box cover gasket which can be used to fix a thermal switch. Background technique [0002] Existing technology: At present, the compressor junction box cover gaskets provided by major compressor manufacturers to air-conditioning manufacturers are mainly divided into two materials: dense and foamed. The dense material has good plasticity and is not easy to deform. It is an ideal material for fixed thermal switches and external protectors (for example, Mitsubishi and Meizhi companies all use this material for gaskets). The foam material has better elasticity, and has a better effect on the sealing of the junction box cover after installation and compression (Highly Company uses this material gasket) [0003] However, the above-mentioned gaskets have the following problems: the use of fully dense gaskets cannot ensure the tightness between the gasket and the surface of the upper case cover aft...
