CONSTITUTION: A case(10) is provided with a detecting surface(12). A core(30) and a printed circuit board(40) are inter-connected and installed on an inside of the case(10). A cap(20) is fit-coupled to an opened internal surface of the case(10) and provided with a pressure projection(24) embedded on a coupler(22). The pressure projection(24) formed on the coupler(22) of the cap(20) is strongly pressed on the inner surface of the case(10) by a forced insertion to strongly couple the case(10) to the cap(20). The pressure projection(24) is a ring-shape to surround an external surface of the coupler(22) of the cap(20).

Description

원주형 근접스위치의 캡 구조 {STRUCTURE OF CAP FOR ROUND-TYPE PROXIMITY SWITCH}Cap Structure of Cylindrical Proximity Switch {STRUCTURE OF CAP FOR ROUND-TYPE PROXIMITY SWITCH}

본 발명은 원주형 근접스위치에 관한 것으로서, 보다 상세하게는 근접스위치의 케이스와 결합되어 그 내부에 설치된 코어 및 인쇄회로기판 등을 보호할 수 있도록 한 원주형 근접스위치의 캡 구조에 관한 것이다.The present invention relates to a cylindrical proximity switch, and more particularly, to a cap structure of a cylindrical proximity switch coupled to the case of the proximity switch to protect the core and the printed circuit board installed therein.

일반적으로, 근접스위치는 검출면에 접근하는 물체 혹은 근방에 존재하는 물체의 유무를 전자계의 힘을 이용하여 기계적 접촉없이 검출하는 스위치로서, 공장 자동화에 광범위하게 사용되고 있다. 그리고 그 형상에 따라 각주형과 원주형으로 크게 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. And it is largely divided into a columnar shape and a columnar shape according to the shape.

종래의 원주형 근접스위치는 도 1에 도시된 바와 같이, 검출면(1)이 형성되는 케이스(2); 상기 케이스(2)의 내부에 상호 연결·설치되는 코어(3) 및 인쇄회로기판(4); 상기 케이스(2)의 개방된 내주면에 끼움 결합되는 캡(5)으로 구성되며, 그 내부가 에폭시 수지로 충진되는 구조를 취하고 있다.Conventional cylindrical proximity switch is shown in Figure 1, the case 2, the detection surface 1 is formed; A core 3 and a printed circuit board 4 interconnected and installed in the case 2; It consists of a cap (5) that is fitted to the open inner peripheral surface of the case (2), and the inside has a structure filled with epoxy resin.

그러나 상기 케이스(2) 및 캡(5)의 결합구조는 캡(5)을 케이스(2) 내주면상에 강제 끼움방식으로 결합함으로써 케이스(2)와 캡(5)의 규격이 조금이라도 일치하지 않을 경우에는 그 결합상태가 느슨해지거나 결합 자체가 곤란해지는 경우가 빈번히 발생되어, 작업효율이 저하되는 것은 물론 제조공정이 지연되는 결과를 초래하고 있었다.However, the coupling structure of the case 2 and the cap 5 is combined by the cap 5 on the inner circumferential surface of the case 2 by force-fitting method so that the specifications of the case 2 and the cap 5 may not match at all. In some cases, the coupling state is loosened or the coupling itself becomes difficult, resulting in a decrease in work efficiency and a delay in the manufacturing process.

그로 인해, 케이스 또는 캡의 직경을 다시 조절해야 하거나 그것이 여의치 않을 경우에는 아예 불량처리해야 하므로 경제적인 측면에서도 문제가 있었다.As a result, the diameter of the case or the cap needs to be adjusted again, or if it is not suitable, there is a problem in terms of economy because it must be treated badly.

본 발명은 상술한 바와 같은 문제점을 감안하여 창출된 것으로, 근접스위치의 케이스와 결합되는 캡의 구조를 개선하여 간단하면서도 견고하게 결합할 수 있는 원주형 근접스위치의 캡 구조를 제공하고자 하는 데 그 목적이 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a cap structure of a cylindrical proximity switch that can be combined simply and robustly by improving the structure of a cap coupled to a case of a proximity switch. There is this.

상기와 같은 목적을 달성하기 위하여 본 발명은, 개방된 일측 단부에는 케이스의 내주면에 끼움 결합되는 결합부가 형성되고, 타측에는 케이블이 관통·삽입되는 케이블삽입구가 구비되는 원주형 근접스위치의 캡에 있어서, 상기 캡의 결합부상에 압착돌기가 일체로 형성되는 데 그 특징이 있다.In order to achieve the above object, the present invention, in the open one end is formed in the coupling portion which is fitted to the inner circumferential surface of the case, the other side in the cap of the cylindrical proximity switch is provided with a cable insertion hole through which the cable is inserted and inserted , It is characterized in that the pressing projection is integrally formed on the coupling portion of the cap.

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 원주형 근접스위치의 사시도이고, 도 3은 본 발명에 따른 원주형 근접스위치의 단면도이며, 도 4는 본 발명에 따른 원주형 근접스위치의 캡 구조를 도시한 사시도이다.2 is a perspective view of a cylindrical proximity switch according to the present invention, Figure 3 is a cross-sectional view of the cylindrical proximity switch according to the present invention, Figure 4 is a perspective view showing the cap structure of the cylindrical proximity switch according to the present invention.

도면에 도시된 바와 같이, 원주형 근접스위치는 검출면(12)이 형성되는 케이스(10); 상기 케이스(10)의 내부에 상호 연결·설치되는 코어(30) 및 인쇄회로기판(40); 상기 케이스(10)의 개방된 내주면에 끼움 결합되며, 그 결합부상(22)에 압착돌기(24)가 일체로 형성되는 캡(20)으로 구성되어 그 내부가 에폭시 수지(50)로 충진되는 구조를 취하고 있다.As shown in the figure, the cylindrical proximity switch includes a case 10 in which a detection surface 12 is formed; A core 30 and a printed circuit board 40 interconnected and installed in the case 10; Fitted to the open inner circumferential surface of the case 10, it is composed of a cap 20, which is formed integrally with the pressing projection 24 on the coupling portion 22, the inside is filled with epoxy resin 50 Is taking.

상기 캡(20)의 결합부(22)상에 형성된 압착돌기(24)는 강제 삽입에 의해 케이스(10)의 내주면상에 강하게 압착되어, 케이스(10)와 캡(20)이 상호 견고하게 결속된 상태를 유지하도록 하는 역할을 수행한다.The pressing protrusion 24 formed on the engaging portion 22 of the cap 20 is strongly pressed onto the inner circumferential surface of the case 10 by forced insertion, so that the case 10 and the cap 20 are firmly bound to each other. It plays a role to keep the state.

상기 압착돌기(24)의 형상은 다양하게 변형 가능하지만, 접촉면이 많아 상대적으로 결속력을 강하게 유지할 수 있는 링 형상을 적용하는 것이 바람직하다.Although the shape of the crimping protrusion 24 can be variously modified, it is preferable to apply a ring shape that can maintain a relatively strong binding force due to the large contact surface.

그리고 상기 압착돌기(24)의 수는 필요에 따라 복수개 형성할 수 있지만, 결합력 및 형성공간 등을 고려하면 하나 또는 둘 정도가 가장 적당하다.The number of the crimping protrusions 24 may be formed in plural as necessary, but one or two is most suitable in view of coupling force and forming space.

상기에서 설명한 캡의 압착돌기는 플라스틱 재질의 캡에 적용되는 것이 일반적이다.The pressing projection of the cap described above is generally applied to the cap of the plastic material.

한편, 공지기술인 근접스위치의 구성 및 기능은 기존의 것과 동일하여 생략하도록 한다.On the other hand, the configuration and function of a known proximity switch is the same as the conventional one to be omitted.

이상에서 상술한 바와 같이 본 발명에 따르면, 캡의 구조를 개선하여 간단하면서도 견고하게 케이스와 결합할 수 있다.As described above, according to the present invention, the structure of the cap can be improved and combined with the case simply and firmly.

또한, 케이스와 캡의 규격이 일치하지 않더라도 압착돌기의 높이에 따른 오차범위 내에서 적용할 수 있다는 장점이 있다.In addition, even if the specifications of the case and the cap does not match, there is an advantage that can be applied within the error range according to the height of the pressing projection.
