본 고안은 통신기기의 키패드스위치 고정장치에 관한 것으로서 특히 실리콘 접착테이프를 삭제하고 하우징의 가이드리브와 인쇄회로 기판의 가이드홀을 사용하여 키패드 스위치를 고정하여 원가를 절감하고 작업불량을 해결할 수 있도록 한 것이다.The present invention relates to a keypad switch fixing device of a communication device, in particular, by removing the silicone adhesive tape and fixing the keypad switch using the guide rib of the housing and the guide hole of the printed circuit board to reduce the cost and solve the work defect. will be.
종래 키패드스위치는 제1도 내지 제3도에서와 같이 폴리돔(2)과 키패드러브(3)가 실리콘 접착 테이프로 일체화된 키패드스위치와, 상기 키패드스위치를 하우징(4)에 고정시키도록 형성된 가이드리브(5)와, 상기 하우징(4)에 말칙 조립되는 인쇄회로기판(1)으로 구성되었다.Conventional keypad switches include a keypad switch in which the polydome 2 and the keypad love 3 are integrated with a silicone adhesive tape as shown in FIGS. 1 to 3, and a guide formed to fix the keypad switch to the housing 4. It consists of a rib 5 and a printed circuit board 1 assembled to the housing 4.
이와 같은 종래의 키패드스위치 고정구조는 폴리돔(2)과 키패드러버(3)가 실리콘 접착테이브로 일체화되고, 하우징의 가이드리브(5)에 키패드러버(3)의 가이드홀을 일치시켜 삽입시켜 고정시키면 인쇄회로기판(1)을 밀착 조립하여 키패드스위치를 고정시킨다.In the conventional keypad switch fixing structure, the polydome 2 and the keypad rubber 3 are integrated with a silicone adhesive tape, and the guide holes of the keypad rubber 3 are inserted into and fixed to the guide ribs 5 of the housing. In this case, the printed circuit board 1 is tightly assembled to fix the keypad switch.
이 때, 제3도에서와 같이 하우징(1)이 설치된 가이드리브(5)는 키패드스위치의 키패드러버(3)만을 고정하게 된다.At this time, as shown in FIG. 3, the guide rib 5 provided with the housing 1 fixes only the keypad rubber 3 of the keypad switch.
그러나 이러한 고정구조는 제3도에서와 같이 하우징의 가이드리브(5)가 키패드스위치러버(3)의 가이드홀만을 고정하므로 폴리돔(2)과 키패드러버(3)의 가이드홀이 일치되지 않아 키패드스위치가 오동작을 일으킬 경우가 발생하게 되고 키패드스위치 제작시 고가의 실리콘 접착테이프를 사용하므로 키패드스위치의 원가가 상승하며 폴리돔과 키패드러버의 접착작업시 가이드홀이 일치되지 않는 불량이 발생하게 되는 문제점이 있었다.However, this fixing structure, as shown in FIG. 3, the guide rib 5 of the housing only fixes the guide hole of the keypad switch rubber 3, so the guide holes of the polydome 2 and the keypad rubber 3 do not coincide. When the switch malfunctions, the expensive silicone adhesive tape is used in the manufacture of the keypad switch, which increases the cost of the keypad switch and causes the defect that the guide hole does not match when the polydome and the keypad rubber are bonded. There was this.
본 고안은 이러한 점을 감안하여 하우징의 가이드리브에 삽입 고정되도록 폴리돔과 키패드러버 그리고 인쇄회로기판에 각각 삽입홀을 형성함으로써, 키패드러버와 폴리돔의 불일치에 의한 오동작을 방지하고 고가의 실리콘 접착테이프를 사용하지 않으므로 생산원가를 절감시키도록 하는데 목적이 있다.In consideration of this, the present invention forms insertion holes in the polydome, keypad rubber, and printed circuit board to be inserted and fixed to the guide rib of the housing, thereby preventing malfunction due to mismatch between the keypad rubber and the polydome and expensive silicone adhesion. Since the tape is not used, the purpose is to reduce the production cost.
본 고안을 제4도 내지 제6도에 의하여 설명한다.The present invention will be described with reference to FIGS. 4 to 6.
하우징(110)의 가이드리브(111) 삽입 고정되도록 폴리돔(108) 및 키패드러버(109)에 각각 삽입홀(105)을 형성하고, 상기 하우징(110) 하부에 밀착조립되는 인쇄회로기판(106)에도 가이드리브(111)가 삽입되도록 삽입홀(105)을 구성하였다.A printed circuit board 106 is formed in each of the polydome 108 and the keypad rubber 109 so that the guide ribs 111 of the housing 110 can be inserted and fixed, and are closely assembled to the bottom of the housing 110. The insertion hole 105 is configured so that the guide rib 111 is also inserted.
이와 같이 구성된 상태에서 키패드스위치의 조립은 제4도와 같이 가이드리브(111)를 가진 하우징(110)에 실리콘 접착테이프를 삭제한 폴리돔(108)과 키패드러버(109)의 삽입홀(105)을 각각 가이드리브(111)에 일치시켜 삽입시키고, 가이드리브(111)의 삽입홀(105)이 형성된 인쇄회로기판(106)이 키패드스위치에 밀착 조립되어 키패드스위치가 하우징(110)에 고정되어지게 되어 종래의 실리콘 접착테이프와 같은 별도의 접착부재를 사용하지 않고도 가이드리브(111)에 의해 키패드스위치를 구성시킬 수 있게 된다.Assembling the keypad switch in the state configured as described above, the insertion hole 105 of the polydome 108 and the keypad rubber 109 in which the silicone adhesive tape is removed from the housing 110 having the guide ribs 111 as shown in FIG. The printed circuit board 106 having the insertion ribs 105 of the guide ribs 111 formed therebetween to be matched with the guide ribs 111 is tightly assembled to the keypad switches so that the keypad switches are fixed to the housing 110. The keypad switch can be configured by the guide ribs 111 without using a separate adhesive member such as a conventional silicone adhesive tape.
이상에서 살펴본 바와 같은 본 고안은 키패드러버와 폴리돔의 불일치에 의한 통신기기의 오동작을 방지할 수 있고 고가의 실리콘 접착테이프 삭제에 의한 생산원가를 절감시킬 수 있는 고안이다.The present invention as described above is to prevent the malfunction of the communication device due to the mismatch between the keypad rubber and the polydome and to reduce the production cost by deleting expensive silicone adhesive tape.
