Description
본 발명은 근접스위치에 관한 것으로서, 보다 상세하게는 근접스위치의 내부공간부상에 충진되는 에폭시 수지가 케이블 내부로 침투되는 것을 미연에 방지할 수 있도록 한 근접스위치의 케이블 실링구조에 관한 것이다.The present invention relates to a proximity switch, and more particularly, to a cable sealing structure of a proximity switch that can prevent the penetration of the epoxy resin filled on the inner space portion of the proximity switch into the cable.
일반적으로, 근접스위치는 검출면에 접근하는 물체 혹은 근방에 존재하는 물체의 유무를 전자계의 힘을 이용하여 기계적 접촉없이 검출하는 스위치로서, 공장 자동화에 광범위하게 사용되고 있다. 그리고 사용목적 및 용도에 따라 여러 종류로 다양하게 구분된다.In general, the proximity switch is a switch that detects the presence or absence of an object approaching or near the detection surface without mechanical contact using the force of an electromagnetic field, and is widely used in factory automation. It is divided into various types according to the purpose of use and use.
종래의 근접스위치는 도 1에 도시된 바와 같이, 케이스(1) 내부공간부상에 코일(2)이 감겨진 보빈(3), 상기 보빈(3)이 수용되는 코어(4), 상기 보빈(3)의 코일(2) 및 외부로 인출되는 케이블(5)과 납땜에 의해 전기적으로 연결되어 있는 인쇄회로기판(6)이 설치되며, 그 내부가 에폭시 수지(7)로 충진되어 있는 구조를 지니고 있다.As shown in FIG. 1, a conventional proximity switch includes a bobbin 3 in which a coil 2 is wound on an inner space of a case 1, a core 4 in which the bobbin 3 is accommodated, and the bobbin 3. Coil (2) and a printed circuit board (6) electrically connected to the cable (5) drawn out to the outside by soldering are installed, and the inside thereof is filled with epoxy resin (7). .
그러나 상기와 같은 구조의 근접스위치는 케이스(1) 내부에 충진되는 에폭시 수지(7)가 케이블(5)의 개방부를 통해 내부로 침투됨으로써 외부로 노출된 케이블(5)이 경화되어 외부 충격에 의해 쉽게 손상되는 경우가 빈번히 발생되었다.However, in the proximity switch of the above structure, the epoxy resin 7 filled in the case 1 penetrates into the inside through the opening of the cable 5 so that the cable 5 exposed to the outside is hardened by external impact. Easily damaged cases occur frequently.
최근에 들어, 이러한 문제점을 보완하기 위하여 에폭시 수지와 접촉되는 케이블에 실리콘을 도포하는 방법이 시도되고 있으나, 이는 작업이 불편할 뿐 아니라 작업시간이 많이 걸렸다.Recently, in order to compensate for this problem, a method of applying silicone to a cable in contact with an epoxy resin has been attempted, but this is not only inconvenient but also takes a lot of work time.
또한, 실리콘에 의해 에폭시와 케이블의 완전부착이 어려워 인장강도가 약해지는 문제점이 있었다.In addition, it is difficult to completely adhere the epoxy and the cable by the silicon, there is a problem that the tensile strength is weakened.
본 발명은 상기와 같은 문제점을 감안하여 창출된 것으로, 실링부재를 이용하여 케이블을 압착시킴으로써 근접스위치 내부의 에폭시 수지가 케이블 내부로 침투되는 것을 방지할 수 있는 근접스위치의 케이블 실링구조를 제공하고자 하는 데 그 목적이 있다. The present invention was created in view of the above problems, and to provide a cable sealing structure of a proximity switch that can prevent the epoxy resin inside the proximity switch from penetrating into the cable by pressing the cable using a sealing member. Its purpose is to.
상기와 같은 목적을 달성하기 위하여 본 발명은, 에폭시 수지로 충진되는 케이스의 일측에 형성된 케이블삽입구 통해 내부의 인쇄회로기판과 전기적으로 연결되고, 외주면에 실링부재가 결합되어지는 케이블을 포함하는 근접스위치의 케이블 실링구조에 있어서, 상기 실링부재의 일단은 상기 케이블삽입구보다 외직경이 작고, 타단으로 갈수록 상기 케이블삽입구보다 외직경이 크게 형성되어 상기 케이블 삽입구 상에 압착ㆍ고정되는데 그 특징이 있다.In order to achieve the above object, the present invention, the proximity switch including a cable that is electrically connected to the printed circuit board inside, the sealing member is coupled to the outer circumference through a cable insertion hole formed on one side of the case filled with epoxy resin In the cable sealing structure, one end of the sealing member has an outer diameter smaller than that of the cable insertion opening, and an outer diameter is formed larger than the cable insertion opening toward the other end, so that the sealing member is crimped and fixed on the cable insertion opening.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
도 2는 본 발명에 따른 근접스위치의 케이블 실링구조를 도시한 단면도이고, 도 3은 본 발명에 따른 실링부재를 도시한 확대사시도이며, 도 4의 (a),(b)는 본 발명에 따른 실링부재의 사용상태도이며, 도 5는 본 발명에 따른 실링부재가 적용된 근접스위치를 도시한 사시도이다.2 is a cross-sectional view showing a cable sealing structure of a proximity switch according to the present invention, Figure 3 is an enlarged perspective view showing a sealing member according to the present invention, Figure 4 (a), (b) is in accordance with the present invention 5 is a perspective view illustrating a proximity switch to which a sealing member according to the present invention is applied.
도면에 도시된 바와 같이, 근접스위치는 에폭시 수지(70)로 충진되는 내부공간부상에 보빈(30), 코어(20) 및 인쇄회로기판(40) 등이 상호 연결·설치되며, 일측에는 케이블삽입구(16)가 형성되는 케이스(10); 상기 케이블삽입구(16)를 통해 케이스(10) 내부로 삽입되어 인쇄회로기판(40)과 전기적으로 연결되는 케이블(50); 상기 케이블(50)의 외주면에 밀착·삽입된 상태에서 케이스(10)의 케이블삽입구(16)상에 압착·고정되는 실링부재(60)로 구성된다.As shown in the figure, the proximity switch is provided with the bobbin 30, the core 20, and the printed circuit board 40, etc. are interconnected and installed on the inner space portion filled with the epoxy resin 70, and one side of the cable insertion opening. A case 10 in which 16 is formed; A cable 50 inserted into the case 10 through the cable insertion hole 16 and electrically connected to the printed circuit board 40; It consists of a sealing member 60 which is crimped and fixed on the cable insertion opening 16 of the case 10 in a state of being in close contact with and inserted into the outer peripheral surface of the cable 50.
상기 실링부재(60)는 케이블(50)을 압착할 수 있는 여러 종류의 재질을 다양하게 적용할 수 있으나, 압착성 및 밀착성이 우수한 고무재질을 사용하는 것이 가장 바람직하다.The sealing member 60 may be variously applied to various kinds of materials capable of compressing the cable 50, but it is most preferable to use a rubber material having excellent compressibility and adhesion.
상기 실링부재(60)의 일단은 케이블삽입구(16)보다 외직경이 작고, 타단으로 갈수록 케이블삽입구(16)보다 외직경이 크게 형성되어 있어, 작업자가 케이블(50)을 일정 강도로 잡아당김으로써 강제 압착방식에 의해 실링 가능하다. 즉, 실링부재(60)가 내부로 압착됨과 동시에 그 내측에 있는 케이블(50)이 압착되어 에폭시 수지(70)가 침투하지 못하게 되며, 설령 침투하더라고 그 양이 미소하여 거의 영향을 미치지 않는다.One end of the sealing member 60 has an outer diameter smaller than that of the cable insertion hole 16, and an outer diameter of the sealing member 60 is larger than the cable insertion hole 16 toward the other end, so that the operator pulls the cable 50 to a certain strength. Sealing is possible by forced crimping. In other words, the sealing member 60 is pressed into the inside and at the same time the cable 50 is pressed inside so that the epoxy resin 70 does not penetrate, even if the penetration is small, the amount is little affect.
한편, 미설명 도면부호 32는 코일을 도시한 것이다.On the other hand, reference numeral 32 denotes a coil.
상기에서 설명한 근접스위치의 케이블 실링구조에 적용된 실링부재의 결합상태를 간단하게 살펴보면 하기와 같다.Looking at the coupling state of the sealing member applied to the cable sealing structure of the proximity switch described above as follows.
먼저, 근접스위치의 케이스(10) 일측에 형성된 케이블삽입구(16)를 통해 내부로 삽입된 케이블(50)의 외주면에 실링부재(60)를 밀착·삽입시킨 후, 작업자가 일정 강도로 케이블(50)을 잡아당김으로써 실링부재(60)가 케이블삽입구(16)상에 강제 압착·고정됨과 동시에 그 내부에 삽입되어 있는 케이블(50)이 압착되는 구조를 취하고 있다.First, the sealing member 60 is brought into close contact with and inserted into the outer circumferential surface of the cable 50 inserted therein through the cable insertion hole 16 formed at one side of the case 10 of the proximity switch. ), The sealing member 60 is forcibly crimped and fixed on the cable insertion opening 16, and the cable 50 inserted therein is crimped.
이러한 근접스위치의 케이블 실링구조는 원주형 근접스위치를 위주로 설명하였지만 각주형 근접스위치에도 적용될 수 도 있을 것이다.Although the cable sealing structure of the proximity switch has been described mainly with the columnar proximity switch, it may also be applied to the columnar proximity switch.
이상에서 상술한 바와 같이 본 발명에 따르면, 에폭시 수지가 케이블 내부로 침투되는 것을 최소화하여 외부에 노출된 케이블이 경화·손상되는 것을 효율적으로 방지할 수 있다.As described above, according to the present invention, it is possible to minimize the penetration of the epoxy resin into the cable and effectively prevent the cable exposed to the outside from being hardened or damaged.
그로 인해, 케이블의 수명을 보다 연장할 수 있어 경제적인 측면에서도 유리하다.Therefore, the service life of the cable can be further extended, which is advantageous in terms of economy.
