Abstract
The invention relates to a junction box cover gasket for fixing a thermal switch. The gasket matches with a junction box cover and a contact part of an upper case of a compressor in shape. The gasket is composed of a foamed part and a dense part. The foamed part matches with the junction box cover and the contact part of the upper case of the compressor in shape. The foamed part is provided with a mounting hole. The dense part is disposed in the mounting hole. The thermal switch on the upper case of the compressor is disposed on the thick part. Compared with the prior art, the junction box cover gasket for fixing the thermal switch has the advantages of simplicity in structure, high airtightness and the like.
Description
Technical field
The present invention relates to a kind of pad, especially relate to a kind of fixedly connector cover pad of thermal switch that can be used for.
Background technology
Prior art: each large compressor manufacturer compressor wiring lid pad of offering air-conditioning producer mainly is divided into two kinds of materials at present: closely knit system and foaming system.Closely knit material has preferably plasticity, not yielding, is more satisfactory material (all having adopted this material pad such as Mitsubishi, Mei Zhi company etc.) for fixedly thermal switch and external protector.Foam material has preferably elasticity, and the sealing of installing after compressing for connector cover has preferably effect (Hai Li company has adopted this material pad)
But above-mentioned pad has following problem: adopt complete closely knit gasket, can't well guarantee to install the sealing between rear pad and the upper shell cover surface; And the foaming prepared material can't form multilayer steps shape thermal switch gland.
| Material | Complete closely knit scheme processed | Full foaming scheme processed |
| Characteristics | Material partially firmly, not yielding | Material is partially soft, good springiness |
| Advantage | The processing one-shot forming | The installation good airproof performance on pad and upper shell cover surface |
| Shortcoming | The sealing on pad and upper shell cover surface is not good | Individual layer pad, inner labyrinth can't one-shot formings |
Summary of the invention
Purpose of the present invention is exactly to provide a kind of fixedly thermal switch connector cover pad simple, good airproof performance of making for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of fixedly thermal switch connector cover pad, the shape of this pad and connector cover and compressor upper shell cover contact portion are complementary, it is characterized in that, described pad is comprised of foaming system part and closely knit system part, the shape of described foaming system part and connector cover and compressor upper shell cover contact portion are complementary, foaming system part is provided with an installing hole, described closely knit system part is arranged in this installing hole, and the thermal switch on the compressor upper shell cover is installed on the closely knit system part.
Described closely knit system part is boss-shaped, and its bottom is provided with the shirt rim, and the upper surface of this shirt rim is bonding with foaming part processed.
Described closely knit system part is by the disposable punch forming of close material, and described close material comprises ethylene propylene diene rubber (EPDM), silica gel or acrylonitrile-butadiene rubber.
Described foaming system partly is to be made by expanded material, and described expanded material comprises PE expanded material or polyurethane foam material.
Compared with prior art, the present invention carries out the new design of pad in conjunction with the advantage of closely knit gasket and two kinds of materials of foaming gasket.Utilize both advantages on material separately, by the bonding mode of adhesive in conjunction with two kinds of materials, obtain more can be safely fixedly thermal switch and guaranteeing sealing, connector cover pad that resistance to deformation is strong are installed.
Description of drawings
Fig. 1 is the vertical view of pad of the present invention;
Fig. 2 is the end view of pad of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
Shown in Fig. 1～2, a kind of fixedly thermal switch connector cover pad, the shape of this pad and connector cover and compressor upper shell cover contact portion are complementary, described pad is comprised of foaming part 1 processed and closely knit part processed 2, the shape of described foaming part 1 processed and connector cover and compressor upper shell cover contact portion are complementary, be to be made by the PE expanded material, have preferably elasticity, the sealing of installing after compressing for connector cover has preferably effect.The part 1 processed that foams is provided with an installing hole, described closely knit part 2 processed is arranged in this installing hole, closely knit part processed 2 is boss-shaped, its bottom is provided with shirt rim 21, the upper surface of this shirt rim 21 is bonding with foaming part processed 1 so that original two kinds of materials separately advantage partly combine, closely knit system is by the disposable punch forming of close material ethylene propylene diene rubber (EPDM) partly, have preferably plasticity, not yielding, the thermal switch on the compressor upper shell cover is installed on the closely knit part processed 2.
It is good fixing that the structure of this new design pad both can guarantee that thermal switch was installed, can guarantee again to install the sealing between the pad and compressor upper shell cover behind the connector cover, the material deformation amount of the comparatively fluffy material behavior of foaming system after also the butted line lid compresses has certain cushioning effect.
Described close material can also be the close materials such as silica gel or acrylonitrile-butadiene rubber.
Described expanded material can also be other expanded materials such as polyurethane foam material.
Claims (4)
