본 발명은 차단턱이 구비된 러버버튼장치에 관한 것으로, 특히 서로 다른 컬러를 갖는 버튼구조의 성형시 버튼과 버튼사이에 차단턱을 형성하므로써, 사출성형시 러버버튼재료가 인접버튼주변영역으로 유입되는 것을 차단하는 차단턱이 구비된 러버버튼장치에 관한 것이다.The present invention relates to a rubber button device provided with a blocking jaw, in particular, by forming a blocking jaw between the button and the button when forming a button structure having a different color, the rubber button material flows into the adjacent button surrounding area during injection molding The present invention relates to a rubber button device having a blocking jaw for preventing it from being.

일반적으로 통신시스템은 제공되는 서비스 종류에 따라 다양한 기능을 갖는시스템들이 사용될 수 있는데, 이러한 다양한 기능을 제어하기 위해서는 필연적으로 입출력제어장치들이 구비되어야 한다. 그런데, 최근에는 상기와 같은 통신시스템에 디지털기술이 접목되어 그 기능이 급속도로 대용량화되어 이를 그 설치된 사양에 따라 정확히 제어하기 위해 복잡한 구조의 입출력제어장치 즉, 제어버튼이나 제어스틱이 포함된 키패드나 키보드부가 개발되어 널리 사용되고 있다.In general, a communication system may be a system having a variety of functions according to the type of service provided, in order to control such a variety of functions must be provided with input and output control devices. However, in recent years, digital technology has been incorporated into the communication system as described above, and its functions are rapidly enlarged, so that an input / output control device having a complicated structure, that is, a keypad including a control button or a control stick, can be precisely controlled according to the installed specifications. The keyboard part has been developed and widely used.

예를들어, 상기와 같은 통신시스템, 특히 개인 휴대통신에 사용되는 셀룰러폰과 같은 단말기에는 다이얼링과 그 밖의 내장기능을 제어하기 위해 숫자나 문자로 표시된 입출력제어장치로서 다양한 종류 예컨대, 투명 혹은 불투명의 4×3 매트릭스의 키패드 버튼들이 사용되고 있다.For example, such a communication system, particularly a terminal such as a cellular phone used for personal mobile communication, is an input / output control device indicated by numbers or letters to control dialing and other built-in functions, and various types, for example, transparent or opaque. 4 x 3 matrix keypad buttons are used.

그러면, 상기와 같은 종래 버튼구조의 일례를 도 1을 참고로 살펴보면, 먼저 일정형상을 갖는 러버프레임부(70)와, 상기 러버프레임부(70)의 전면에 일정간격을 두고 숫자나 문자 형태의 식별기호가 인쇄된 버튼부(71A-N)가 형성된다.Then, referring to an example of the conventional button structure as described above with reference to Figure 1, first, the rubber frame portion 70 having a predetermined shape, and the rubber frame portion 70 in the form of numbers or letters at a certain interval on the front Button portions 71A-N having the identification symbols printed thereon are formed.

여기서, 상기 버튼부(71A-N)는 러버버튼재료 예컨대, silicon rubber를 이용하여 사출성형된 투명버튼 혹은 불투명버튼을 모두 포함한다.Here, the button portion 71A-N includes both a transparent button or an opaque button injection molded using a rubber button material, for example, silicon rubber.

한편, 상기와 같은 종래 버튼구조의 제조방법을 살펴보면, 먼저 일정 버튼형상이 도 1의 (a)-(c)에 도시된 바와같이 사출되도록 형성된 금형구조(72)내에 러버버튼재료 예컨대, silicon rubber재료를 주입하여 사출성형하는데, 이때 투명버튼(71A)에는 투명수지를 주입하고, 불투명 버튼(71B-N)에는 불투명수지를 주입하여 버튼구조를 제조한다.On the other hand, looking at the manufacturing method of the conventional button structure as described above, first, a rubber button material, for example, silicon rubber in the mold structure 72 is formed so that a predetermined button shape is injected as shown in (a)-(c) of Figure 1 The injection molding is performed by injecting the material. At this time, the transparent button 71A is injected with the transparent resin, and the opaque buttons 71B-N are infused with the opaque resin to manufacture the button structure.

상기와 같은 과정에 의해 버튼구조가 완성되면 외부에서 볼 때 투명버튼(71A)은 자신의 내부에 빛이 관통하게 되므로 이 투명버튼(71A)의 내부바닥면상에 인쇄되어 있는 숫자나 문자를 식별할 수 있다. 반면에 불투명버튼(71B-N)은 내부를 관출할 수가 없다.When the button structure is completed by the above process, when the transparent button 71A is seen from the outside, light penetrates the inside thereof so that the number or letter printed on the inner bottom surface of the transparent button 71A can be identified. Can be. On the other hand, the opaque buttons 71B-N cannot observe the inside.

그러나, 상기와 같은 종래 버튼구조는 임의의 버튼과 이 버튼에 인접한 다른 버튼사이의 경계면이 평탄하기 때문에 사출성형시 인접한 버튼 형성을 위한 수지재료가 이 경계면을 통해 침투되어 사출불량을 야기하므로 그에 따라 버튼구조의 제조수율을 상당히 저하시켰으며, 또한, 사출성형시 인접한 경계면을 통해 칼라가 서로 다른 수지가 인접 버튼측으로 침투할 경우 고가의 러버버튼구조를 모두 다시 제조해야하므로 그에 따라 버튼구조의 제조비용을 상당히 증가시키는 문제점을 야기시켰다.However, in the conventional button structure as described above, since the interface between an arbitrary button and another button adjacent to the button is flat, the resin material for forming an adjacent button penetrates through the interface during injection molding, thereby causing an injection failure. The manufacturing yield of the button structure was considerably lowered. Also, in case of injection molding, if the resin with different colors penetrates to the adjacent button side through the adjacent interface, all the expensive rubber button structures must be manufactured again. This causes a problem that increases considerably.

이에 본 발명은 상기와 같은 종래 제반 문제점을 해결하기 위해 발명된 것으로, 서로 다른 컬러를 갖는 버튼구조의 성형시 버튼과 버튼사이에 차단턱을 형성하므로써, 사출성형시 러버버튼재료가 인접버튼주변영역으로 유입되는 것을 차단하게 되므로 그에 따라 러버버튼장치의 제조수율을 향상시키는 차단턱이 구비된 러버버튼장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by forming a blocking jaw between the button and the button when forming a button structure having a different color, the rubber button material is adjacent to the adjacent button area during injection molding It is an object of the present invention to provide a rubber button device having a blocking jaw to improve the production yield of the rubber button device accordingly to block the flow into.

본 발명의 다른 목적은 차단턱을 통해 서로 다른 수지의 경계에서 러버버튼재료의 주입을 용이하게 조절할 수 있으므로 그에 따라 러버버튼장치의 작업성도 상당히 향상되는 차단턱이 구비된 러버버튼장치를 제공하는데 있다.Another object of the present invention is to provide a rubber button device with a blocking jaw that can easily adjust the injection of the rubber button material at the boundary of different resins through the blocking jaw, thereby significantly improving the workability of the rubber button device. .

상기와 같은 목적을 달성하기 위한 본 발명은 일정형상의 매트릭스구조를 갖는 러버프레임부를 갖는 전자시스템에서, 상기 전자시스템의 일부에 구비되고, 일정 칼라를 갖는 제1 버튼부의 주변바닥면에 일정형상으로된 차단턱을 형성하며 이 차단턱을 경계면으로 하여 제2 버튼부가 형성된 러버프레임부를 포함하는 차단턱이 구비된 러버버튼장치를 제공한다.The present invention for achieving the above object in the electronic system having a rubber frame portion having a predetermined matrix structure, which is provided in a part of the electronic system, and in a predetermined shape on the peripheral bottom surface of the first button portion having a predetermined color The present invention provides a rubber button device having a blocking jaw including a rubber frame part in which a second button part is formed, the blocking jaw being formed and having the blocking jaw as an interface.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 러버버튼장치는 도 2에 도시된 바와같이 통신시스템 예컨대, 일정형상을 매트릭스구조를 갖는 러버프레임부(1)와, 상기 러버프레임부(1)의 일정위치에 예컨대, 유자형상으로 차단턱(2)이 형성된 일정 칼라를 갖는 제1 버튼부(3)와, 상기 차단턱(2)을 경계면으로 하여 사출성형시 사출재료가 격리되어 버튼구조를 형성하는 제2 버튼부(4)로 구성된다.As shown in FIG. 2, the rubber button device of the present invention blocks a predetermined shape of the rubber frame part 1 having a matrix structure and a rubber frame part 1 at a predetermined position of the rubber frame part 1, for example, in a zigzag shape. The first button part 3 having a predetermined collar having the jaw 2 formed thereon, and the second button part 4 having the button jaw 2 as an interface to separate the injection material during injection molding to form a button structure. It is composed.

여기서, 상기 차단턱(2)은 도 1의 (b)에 도시된 바와같이 단면으로 볼 때 러버프레임부(1)를 형성하는 하부금형틀(5)의 바닥면에서 돌출된 구조로 형성되므로, 서로 다른 칼라를 갖는 제1 버튼부(3)와 제2 버튼부(4)가 러버프레임부(1)상에 사출성형될 경우 서로 다른 칼라의 버튼재료가 이 차단턱(2)을 경계면으로 하여 더 이상 다른 버튼부로 침투되지 못하도록 하는 구조이다.Here, since the blocking jaw (2) is formed in a structure protruding from the bottom surface of the lower mold frame (5) forming the rubber frame portion 1 when viewed in cross section as shown in (b) of FIG. When the first button part 3 and the second button part 4 having different colors are injection molded on the rubber frame part 1, the button material of different colors has the blocking jaw 2 as an interface. It is a structure that can no longer penetrate other buttons.

그리고, 상기 제1 버튼부(3)와 제2 버튼부(4)의 칼라는 정해진 것이 아니며, 해당 제품의 설계에 따라 이들의 칼라가 선택되는 것이므로, 본 발명에서는 이에 국한되지 않는다. 다만, 본 발명의 일실시예에서는 상기 제1 버튼부(3)를 투명재료로 형성하고 제2 버튼부(4)는 불투명재료로 형성하는 것으로 설명한다.In addition, since the color of the first button part 3 and the second button part 4 is not determined, and their color is selected according to the design of the product, the present invention is not limited thereto. However, in the exemplary embodiment of the present invention, the first button part 3 is formed of a transparent material, and the second button part 4 is described as being formed of an opaque material.

다음에는 상기와 같은 본 발명의 러버버튼장치의 제조방법을 설명한다.Next, a method of manufacturing the rubber button device of the present invention as described above will be described.

본 발명의 러버버튼장치는 도 3에 도시된 바와같이 초기상태(S1)에서 금형틀 조립단계(S2)로 진행하여 버튼과 버튼을 격리하는 차단턱을 갖는 러버버튼장치를 형성하는 금형틀을 조립한다. 그리고, 상기 금형틀 조립단계(S2)후에 사출성형단계(S3)로 진행하여 조립된 차단턱을 가진 금형틀에 칼라가 서로 다른 버튼재료를 해당 부위에 주입하여 사출성형한다.In the rubber button device of the present invention, as shown in FIG. 3, the mold frame is formed to form a rubber button device having a blocking jaw that separates the button from the button by proceeding to the mold frame assembling step (S2). do. Then, after the mold assembly step (S2) to proceed to the injection molding step (S3) to the injection molding mold having a cutoff jaw different color button material is injected into the corresponding site.

이때, 상기 사출성형단계(S3)에 의해 사출성형시 버튼재료가 차단턱에 의해 인접 버튼부로 침투되는 것이 차단된다.At this time, the injection molding step (S3) is blocked when the injection molding button material to the adjacent button portion by the blocking jaw.

한편, 상기 사출성형단계(S3)후에 러버버튼장치 완성단계(S4)로 진행하여 금형틀에 의해 제작된 일부 버튼과 버튼사이에 차단턱을 갖는 러버버튼장치를 금형틀로부터 분리하여 해당 전자시스템에 조립시킨다.On the other hand, after the injection molding step (S3) proceeds to the rubber button device completion step (S4) to remove the rubber button device having a blocking jaw between the button and some buttons produced by the mold frame from the mold frame to the electronic system Assemble

환언하면, 상기 버튼(3)과 버튼(4)사이가 버튼 재료로부터 격리되도록 도 1의 (a)-(c)에 도시된 바와같이 차단턱(2)이 형성된 상,하 금형틀(5,6)을 조립하고버튼재료를 금형틀(5,6)에 주입하면 도 1의 (a)에 도시된 바와같이 다수의 버튼들을 갖는 러버버튼장치가 사출성형된다. 이때, 상기 사출성형시 금형틀(5,6)의 하부면에 돌출되어 있는 차단턱(2)에 의해 버튼(3)과 인접버튼(4)의 경계면에는 통로(7)가 매우 작게 형성된다. 따라서, 상기 버튼(3)과 버튼(4)사이의 통로가 매우 작기 때문에 사출성형시 버튼재료의 흐름이 순간적으로 차단되게 되어 이 버튼재료가 인접버튼으로 침투되는 것이 방지된다.In other words, the upper and lower mold frame 5, in which the blocking jaw 2 is formed, as shown in FIGS. 1 (a)-(c) so that the button 3 and the button 4 are separated from the button material. 6) After assembling and injecting the button material into the molds 5 and 6, the rubber button device having a plurality of buttons is injection molded as shown in FIG. At this time, the passage 7 is formed on the interface between the button 3 and the adjacent button 4 by the blocking jaw 2 protruding from the lower surface of the mold 5, 6 during the injection molding. Therefore, since the passage between the button 3 and the button 4 is very small, the flow of the button material is momentarily interrupted during injection molding, thereby preventing the button material from penetrating into the adjacent button.

즉, 상기 버튼재료가 금형틀(5,6)내에서 일정한 두께로 성형되어지다가 차단턱(2)에 의해 형성된 통로(7)를 통과할 때, 이 통로가 매우 좁기 때문에 순간적으로 버튼재료의 흐름이 차단되어 그 상태로 성형되게 된다. 따라서, 이와같이 차단턱(2)의 작용에 의해 버튼재료가 인접버튼으로 유입되는 것이 완전차단되므로 그에 따라 사출성형시 버튼재료에 의해 발생되는 사출불량을 현저히 감소되게 된다.That is, when the button material is molded to a certain thickness in the mold 5, 6 and passes through the passage 7 formed by the blocking jaw 2, the passage of the button material is instantaneously because the passage is very narrow. Is cut off and molded in that state. Therefore, since the button material is completely blocked from flowing into the adjacent button by the action of the blocking jaw 2 as described above, the injection failure caused by the button material during injection molding is significantly reduced.

한편, 상기와 같은 사출성형과정을 거쳐 제조된 본 발명의 버튼러버장치는 다양한 칼라를 갖는 버튼을 다수개 형성한다하더라도 차단턱(2)에 의해 인접버튼에 영향을 미치지 않으므로 매우 우수한 작업공정을 이룰 수 있다.On the other hand, the button rubber device of the present invention manufactured through the injection molding process as described above does not affect the adjacent button by the blocking jaw (2) even if a plurality of buttons having a variety of colors to achieve a very excellent work process Can be.

이상 설명에서와 같이 본 발명은 서로 다른 컬러를 갖는 버튼구조의 성형시 버튼과 버튼사이에 차단턱을 형성하므로써, 사출성형시 러버버튼재료가 인접버튼주변영역으로 유입되는 것을 차단하게 되므로 그에 따라 러버버튼장치의 제조수율을 향상시키는 장점을 가지고 있다.As described above, the present invention forms a blocking jaw between the button and the button when forming a button structure having different colors, thereby preventing the rubber button material from flowing into the adjacent button surrounding area during injection molding. It has the advantage of improving the manufacturing yield of the button device.

또한, 본 발명에 의하면, 차단턱을 통해 서로 다른 수지의 경계에서 러버버튼재료의 주입을 용이하게 조절할 수 있으므로 그에 따라 러버버튼장치의 작업성도 상당히 향상되는 효과도 있다.In addition, according to the present invention, since the injection of the rubber button material can be easily adjusted at the boundary of the different resin through the blocking jaw, there is also an effect that the workability of the rubber button device is significantly improved.
