Description

공기 조화기의 압축기용 전장품의 고정구조{Structure for fixing electric devices for a compressor in an air conditioner}Structure for fixing electric devices for a compressor in an air conditioner

본 발명은 공기조화기의 압축기용 전장품을 체결수단을 이용하여 플라스틱 사출물에 고정하는 구조에 관한 것으로서, 보다 상세하게는 플라스틱 사출물의 체결력을 보강하는 금속재의 고정판에 체결수단이 체결됨으로써 전장품을 견고하게 고정할 수 있는 구조에 관한 것이다.The present invention relates to a structure for fixing the electrical equipment for compressor of the air conditioner to the plastic injection molding using the fastening means, and more particularly, the fastening means is fastened to the fixing plate of the metal material to reinforce the fastening force of the plastic injection molding It is about structure which can be fixed.

일반적으로, 압축기를 작동시키기 위한 전장품은 나사와 같은 체결수단에 의해 플라스틱 사출물에 고정된다. 그러나, 플라스틱 사출물은 재료의 특성상 나사를 여러번 풀고 조이는 과정에서 체결부의 암나사부가 쉽게 마멸되는 단점이 있다. 이러한 단점은 나사를 그 체결부에 조이고 푸는 과정을 10회 반복하는 체결부의 암나사부의 마멸에 대한 안전시험과 관련하여 제품의 불합격 요인이 된다.Generally, the electrical equipment for operating the compressor is fixed to the plastic injection molding by fastening means such as screws. However, the plastic injection molding has a disadvantage in that the female thread part of the fastening part is easily worn in the process of loosening and tightening the screw many times due to the characteristics of the material. This drawback is a failure of the product in relation to the safety test for the wear of the female thread part of the fastening part that repeats the process of tightening and loosening the screw 10 times.

이에 대한 해결책으로서, 금속재의 체결부를 인서트(insert)로 사용한 인서트 사출공정에 의해 플라스틱 사출물이 성형된다. 이러한 사출공정에 의해 성형된 플라스틱 사출물이 도 1에 도시되어 있다.As a solution to this, the plastic injection molded product is molded by an insert injection process using a fastening part of a metal material as an insert. The plastic injection molded by this injection process is shown in FIG. 1.

도 1을 참조하면, 플라스틱 사출물(10a)에는 나사(30a)에 의해 체결되는 너트의 역할을 하는 인서트(5)가 매립되어 있다. 이 인서트(5)는 그 내주면에 암나사부가 형성되어 있다. 터미널 블럭(7) 및 마그네트 스위치(8)와 같은 전장품을 고정하기 위한 나사(30)가 인서트(5)와 나사결합된다.Referring to FIG. 1, an insert 5 serving as a nut fastened by a screw 30a is embedded in the plastic injection molding 10a. The insert 5 has a female threaded portion formed on an inner circumferential surface thereof. Screws 30 for fastening electrical components such as the terminal block 7 and the magnet switch 8 are screwed into the insert 5.

이와 같은 인서트 사출공정은 나사에 의한 체결력을 충분히 확보할 수 있다는 장점에도 불구하고 제조공정의 특성상 제조 단가가 통상의 사출공정보다 값비싸다는 단점이 있다.Such an insert injection process has a disadvantage in that a manufacturing cost is more expensive than a normal injection process in view of the characteristics of the manufacturing process, despite the advantage that the fastening force by the screw can be sufficiently secured.

전술한 단점을 해결하기 위한 본 발명의 목적은 고가의 인서트 사출공정이 아닌 저가의 일반 사출공정에 의해 성형된 플라스틱 사출물에 전장품을 견고하게 고정할 수 있는 공기조화기의 압축기용 전장품의 고정구조를 제공하는 것에 있다.An object of the present invention for solving the above-mentioned disadvantages is to provide a fixed structure of a compressor electrical equipment for an air conditioner that can firmly fix the electrical equipment to a plastic injection molded by a low-cost general injection process rather than an expensive insert injection process. It is to offer.
