본 고안은 VTR의 카세트하우징의 상판등에 고정되어 카세트하우징내의 카세트가 삽입되었는지의 유무를 판별하기 위한 리프(LEAF)스위치의 안전 동작장치에 관한것으로 특히 접점을 보호할수 있는 캡을 씌워 하측의 한쪽방향에서만 동작할 수 있도록 한 리프스위치의 안전동작장치에 관한 것이다.The present invention relates to a safety operation device of a leaf (LEAF) switch, which is fixed to the upper plate of a cassette housing of a VTR, to determine whether or not a cassette is inserted in the cassette housing. It relates to a safety operation device of the leaf switch to operate only at.

일반적으로 사용되는 리프스위치는 상, 하측에서 동작편에 힘이 가해지면 스위띠가 동작하도록 구성되있어 한쪽방항에서 작동을 요구하게 될 경우 충격 또는 외력에 의해서 오동작이 발생하는 등의 결점이 있었다.In general, the leaf switch used is configured to operate the switch when the force is applied to the moving piece from the upper and lower sides, and if there is a demand for operation in one direction, a malfunction occurs due to an impact or an external force.

따라서 본 고안은 상기에서와 같은 종래의 결점을 해결하기 위하여 스위치의 하측에서 동작시키는 힘이 전달 되면 스위치가 동작할수 있도록 되어있으며 상측에서 누를경우에는 파측 단자편이 자동적으로 밀려 동작하지 않도록 안출한 것으로 이를 첨부된 도면에 따라서 본 고안의 실시예를 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to operate the switch when the force acting on the lower side of the switch in order to solve the conventional drawback as described above, and when pressed from the upper side, the side of the terminal piece is automatically pushed out so that it does not work. Referring to the embodiments of the present invention in detail according to the accompanying drawings as follows.

제1도와 제2도에 도시한 바외같이 리프스위치(1)에는 둥근형의 동작편(2)과 상, 하단자편(3), (4)을 보호하는 접점보호캡(1)이 일체로 형성되어 있으며 접점보호캡(1)내부 양측으로는 상기 하측 단자편(3)에 몰딩시킨 동작 누름편(5)이 끼워질 수 있는 가이드홈(1a)과 상측동작방지편(6)의 힌지축(7)이 끼워질수 있는 힌지부(8)가 각각 형성되어 있다.As shown in FIG. 1 and FIG. 2, the leaf switch 1 is integrally formed with a contact protection cap 1 for protecting the round operation piece 2 and the upper and lower magnetic strip pieces 3 and 4. The hinge shaft 7 of the guide groove 1a and the upper anti-operation piece 6 into which both of the inner side of the contact protection cap 1 can be fitted the operation pressing piece 5 molded into the lower terminal piece 3. Each hinge portion 8 into which the) can be fitted is formed.

또 상술한 단자편의 동작누름편(5)은 접점(3a)과 근접되어 있으며 하측단자편(3)을 보호캡(1) 내부에서 유동되지 않도록 가이드홈(1a)에 고정하는 역활을 하게되고 하측단자편(3)이 끼워져 몰딩시킬수 있는 통공(5a)이 뚫려 있으며 뿔모양의 방지편(6)은 접점보호캡(1)양측 내부의 가이드홈(1a)에 뚫려있는 힌지부(8)에 끼워져 회전할 수 있도록 힌지축(7)이 돌설되어 있으며 방지편(6)상부에는 하측 단자편(3)이 상측 단자편(4)과 접점하고 원위치로 돌아올때 상측단자편(4)이 하측단자편(3)에 접촉되어 오동작하는 것을 막기위한 받침대(6a)가 형성되어 있다.In addition, the operation pressing piece 5 of the terminal piece is close to the contact point 3a and serves to fix the lower terminal piece 3 to the guide groove 1a so as not to flow inside the protective cap 1 and to the lower side. The terminal piece 3 is inserted into the through hole 5a which can be molded, and the horn shaped prevention piece 6 is inserted into the hinge part 8 which is drilled in the guide groove 1a inside the contact protection cap 1. The hinge shaft 7 is protruded so as to rotate, and the upper terminal piece 4 is lower terminal piece when the lower terminal piece 3 contacts the upper terminal piece 4 and returns to its original position on the upper part of the prevention piece 6. A pedestal 6a is formed to prevent contact with (3) and malfunction.

또한 리프스위치의 상, 하측 단자편(4), (3)이 타물질이나 외부로 부터의 충격으로 파손되는 것을 막기위하여 몸체(11)의 상측에는 상측보호편(10)이 몸체(11)의 하측에는 하측보호편(9)이 형성된 것으로 도면중 미설명 부호 (11a)는 접편인출편이고(12)는 고정부이며 (12a)는 고정홈이며 (13)은 고정구멍 (14)는 카세트 하우징 상판, (14a)는 돌출부를 나타낸 것이다.In addition, in order to prevent the upper and lower terminal pieces 4 and 3 of the leaf switch from being damaged by impacts from other materials or from outside, the upper protective piece 10 is provided on the upper side of the body 11. In the drawing, a lower protective piece 9 is formed, and reference numeral 11a in the figure indicates that the piece is pulled out, 12 is a fixing part, 12a is a fixing groove, and 13 is a fixing hole 14 that is a cassette housing upper plate. , 14a represents the protrusion.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안의 리프스위치는 하측에서 스위치를 동작하는 힘이 동작편(2)에 가해지면 동작편(2)과 일체로 제작된 접점보호캡(1)이 위로 작동하면서 접점보호캡(1)내부양측의 가이드홈(1a)에 끼워져 있는 동작 누름편(5)에 의하여 하측단자편(3)이 접점보호캡(1)과 함께 상측으로 이동하면서 상측단자편(4)에 접점이 된다. 이때 하측 단자편(3)이 끼워져 있는 방지편(6)은 양측의 힌지축(7)이 접점보호캡(1) 내부의 양측에 형성된 가이드홈(1a) 에 힌지부(8)에 끼워져 있기때문에 이것을 기준점으로 하측단자편(3)이 벤딩되어 하측 접편(3)이 윗쪽으로 작동할때 방지편(6)상측의 받침대(6a)가 구조상 상측단자편(4)에 미끄러져 작동될수 있도록 일정한 각도로 경사를 주어 방지편(6)이 약간 회동하면서 경사면이 상측단자편(4)과 거의 평행상태로 되면서 하측단자편(3)의 접점 (3a)이 상측단자편(4)의 접점(4a)에 스위치 접속된다.In the leaf switch of the present invention, when a force for operating the switch from the lower side is applied to the operation piece 2, the contact protection cap 1 manufactured integrally with the operation piece 2 operates upward while both sides of the contact protection cap 1 operate. The lower terminal piece 3 is brought into contact with the upper terminal piece 4 while the lower terminal piece 3 moves upward with the contact protection cap 1 by the operation pressing piece 5 fitted in the guide groove 1a. In this case, in the prevention piece 6 in which the lower terminal piece 3 is fitted, the hinge shafts 7 on both sides are fitted to the hinge portion 8 by guide grooves 1a formed on both sides of the inside of the contact protection cap 1. When the lower terminal piece (3) is bent as a reference point and the lower contact piece (3) operates upward, the base 6a on the upper side of the prevention piece (6) can be slid to operate on the upper terminal piece (4). The inclined surface becomes substantially parallel to the upper terminal piece 4 while the prevention piece 6 is rotated slightly, and the contact point 3a of the lower terminal piece 3 is the contact point 4a of the upper terminal piece 4. Is connected to the switch.

그리고 반대로 상측에서 접점보호캡(1)이 하측으로 작동하게 되면 하측단자편(3)에 몰딩되어 가이드홈(1a) 에 끼워진 동작누름편(5)에 의해 보호캡과 함깨 하측단자편이 방지편(6)의 힌지축(7)을 중심으로 벤딩되고 동시에 방지편의 받침대(6a)가 회동하여 수직하게 됨으로써 상측 단자편(4)을 밀게되고 이때 상측단자편(4)은 자체탄성으로 수평을 유지하여 접점접속이 불가능하게 된다.On the contrary, when the contact protection cap (1) from the upper side is operated to the lower side is molded in the lower terminal piece (3) and the lower terminal piece together with the protective cap by the operation pressing piece (5) fitted in the guide groove (1a) ( 6) is bent around the hinge shaft (7) and at the same time the base of the prevention piece (6a) is rotated and vertical to push the upper terminal piece (4) at this time the upper terminal piece (4) to maintain the level of its own elastic Contact connection becomes impossible.

그리고 이와같은 스위치동작시 상측보호편(10)과 하측 보호편(9)은 외부로부터 의 충격이나 휘어짐으로 부터 상측단자편(4)과 하측단자편(3)을 보호하기 위한 장치이며 스위치의 고정부(12)는 카세트하우징상판(14)에 조립시킬때 고정홈(12a)이 안내역활을 하며 고정구(12)의 고정구(13)에 세트의 돌출부(14a)가 끼워짐으로서 스위치의 유동과 이탈을 방지하도록된 것이다. 또한 몸체(11)의 접편인출편(11a)은 외부연결선과 연결할 수 있는 연결단자이다.In this switch operation, the upper protective piece 10 and the lower protective piece 9 are devices for protecting the upper terminal piece 4 and the lower terminal piece 3 from impact or bending from the outside. When the government part 12 is assembled to the cassette housing upper plate 14, the fixing groove 12a serves as a guide, and the protrusion 14a of the set is fitted into the fixture 13 of the fixture 12 so that the flow and departure of the switch can be achieved. It is to prevent. In addition, the contact piece pull-out piece (11a) of the body 11 is a connection terminal that can be connected to the external connection line.

이상과 같이 본 고안은 종래스위치의 양상인 보호캡 전체로 스위치를 감싸거나 양쪽에서 힘이 가해질경우 오동작을 할수 있는 소지를 많이 가지고 있었으며 작동후의 진동이나 타물체에 의해 오동작이 발생하는 결점을 해소하기 위하여 스위치의 단자편에 접점방지편을 설치하여 한쪽방향에서만 동작할수 있도록 구성설계함으로서 오동작방지와 세트의 신뢰성을 극대화시킬수 있도록 한 장점이 있는 것이다.As described above, the present invention has a lot of possibility of malfunction when the switch is wrapped around the entire protective cap which is an aspect of the conventional switch or when the force is applied from both sides, and it is possible to solve the defect that the malfunction occurs due to vibration or other object after operation. In order to prevent the malfunction and maximize the reliability of the set by installing the contact prevention piece on the terminal piece of the switch to operate only in one direction.
