본 고안은 압지편을 형성한 압지구의 상면으로 LED가 현출되도록 끼움고정시켜 구성한 키보드의 연성 PCB에 접속하는 LED 접속구에 관한 것으로 사용시에 LED의 리드선 양단자가 키보드의 연선 PCB에 안전하고 용이하게 접속되도록 키보드의 상면판에 끼워물림시킬 수 있게함에 목적을 둔것이다.The present invention relates to an LED connector for connecting to the flexible PCB of the keyboard formed by fitting the LED to emerge to the upper surface of the pressure-dial forming the tack piece, so that both ends of the LED lead wire to be safely and easily connected to the stranded PCB of the keyboard when in use The purpose is to allow the keyboard to snap into the top panel of the keyboard.
종래에 에폭시 수지로된 PCB인 경우는 경질로서 내열성이 양호하여 LED를 납땜하여 사용할 수 있었으나, 이는 에폭시 수지가 고가이므로 원료구입에 따른 경제적인 부담이 크고 또한 리드선 양단자를 별도로 납땜을 하여야되는 작업공정이 까다로운 결점으로 인하여 실용성이 적어지고 있는 실정인데 대하여 연성 PCB 동 박판이 실용화되고 있는 것이다.In the case of the conventional PCB made of epoxy resin, it was hard and had good heat resistance, so it could be used by soldering LED. However, since the epoxy resin is expensive, the economic burden due to the purchase of raw materials is large and the both ends of the lead wire must be soldered separately. Due to this difficult drawback, the practicality of the use is less, the flexible PCB copper sheet is being used.
일반적으로 연성 PCB인 경우는 연질로서 내열성이 약하여 납땜을 할수가 없으므로 LED의 리드선 양단자를 동박가판에 접지하여 꽂아둔 상태로서 지지시켜 사용되고 있으므로 사용중에 키보드 본체를 이동할 때 흔들림으로 인하여 동박판에 접지된 상태인 LED의 리드선단자가 동박판에서 이탈되어 접속상태가 불량하거나 동박판이 손상되는 결점이 있었다.In general, the flexible PCB is soft and has low heat resistance and cannot be soldered. Therefore, both ends of the LED lead wires are grounded and plugged into the copper foil board, which is used to support the PCB. There was a defect that the lead terminal of the LED in the state was separated from the copper foil and thus the connection state was poor or the copper foil was damaged.
본 고안은 종래의 결점을 적게하기 위하여 LED의 리드선 양단자를 별도로 형성한 압지구에 끼움고정시켜 구성한 LED접속구를 키보드본체의 상면판 뚫은 구멍에 끼워물림시켜주므로서 LED의 리드선 양단자가 동박판에 안전하고 용이하게 접속될 수 있도록 고안된 것으로서 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to reduce the shortcomings of the prior art, the LED connector formed by fitting both ends of the LED lead wires into the squeezing holes formed separately is inserted into the hole formed in the upper plate of the keyboard body to secure the copper foil plate. It is designed to be easily connected to and described in detail by the accompanying drawings as follows.
양측에 구멍(3)(3a)을 뚫은 "+"자형의 절연체(1)의 하방에 극성이 다른 도전성 고무(2)(2a)를 양분되게 접착시켜 "+"자형의 절연체(1)의 양측에 뚫은 구멍(3)(3a)으로 공지한 LED (4)의 리드선 양단자(5)(5a)끼워 도전성고무(2)(2a)에 끼워물림시킨 다음 걸림턱(P)(T)을 가진 압지편(6)(6a)을 형성한 압지구(7)에 공지한 LED (4)가 현출되도록 접착고정시켜서된 접속구(8)를 국성이 다른 도전성고무(2)(2a)가 연성 PCB(9)의 동막(10)(10a)에 접지되도록 공지한 키보드 본체 상면판(11)에 뚫은 사각구멍(12)에 끼워 물림시켜서 된 것이다.Both sides of the " + " insulator 1 are formed by bidirectionally bonding conductive rubbers 2 and 2a of different polarity to the lower side of the " + " insulator 1 having bored holes 3 and 3a on both sides. Both ends of the lead wires 5, 5a of the LED 4, known as holes 3, 3a, are fitted into the conductive rubbers 2, 2a, and then have a locking step P (T). The conductive rubbers 2 and 2a having different nationalities are connected to the connector 8 formed by adhesively fixing the known LEDs 4 to the squeezing holes 7 on which the squeezing pieces 6 and 6a are formed. It is made by being fitted into the square hole 12 drilled in the keyboard body upper plate 11 which is known to be grounded to the copper film 10, 10a of 9).
도면중 미설명부호(10')(10a')는 절연막이다.In the drawings, reference numerals 10 'and 10a' denote insulating films.
이와같이 본 고안은 "+"형의 절연체(1) 하방으로 극성이 다른 도전성고무(2)(2a)의 쇼트를 방지할 수 있도록 양분되게 접착시켜 LED의 리드선 양단자(5)(5a)를 절연체(1)의 양측구멍(3)(3a)으로 끼워 상기 도전성고무(2)(2a)에 끼워물림상태로서 LED가 압지구(7)의 상면으로 현출되도록 압지구(7)의 내저부로 끼움고정시킴으로 접속구(8)가 구성되는 것이며 이와같이 구성된 접속구(8)를 사용할 때에는 미리 사각구멍(12)의 하방인 키보드본체내에 설치한 연성 PCB(9)의 동막(10)(10a)이 표출되도록 다층구조의 PCB 절연막을 탈피시켜놓은 상태이므로 압지구(7)의 양측에 형성된 압지편(6)(6a)을 눌러주면서 키보드본체의 상면판(11)에 뚫은 사각구멍(12)에 끼워넣어 주게되면, 압지편(6)(6a)의 걸림터(P)(T)이 사각구멍(12)의 턱에 물림과 동시에 접속구(8)의 하단부인 극성이 다른도전성고무(2)(2a)가 연성 PCB(9)의 동막(10)(10a)에 안전하게 접지된 상태로서 고정되게 되는 것이다.In this way, the present invention adheres bidirectionally under the "+" type insulator 1 so as to prevent shorting of the conductive rubbers 2 and 2a having different polarities so that both ends of the LED lead wires 5 and 5a are insulated. Inserted into both side holes (3) and (3a) of (1), it is fitted into the conductive rubber (2) and (2a), and the LED is inserted into the inner bottom of the squeegee 7 so that the LED emerges from the upper surface of the squeegee 7. The connector 8 is formed by fixing, and when using the connector 8 configured in this way, the multilayer film 10 and 10a of the flexible PCB 9 installed in the keyboard body below the square hole 12 in advance are exposed. Since the PCB insulating film of the structure is peeled off, it is inserted into the square hole 12 drilled in the upper plate 11 of the keyboard main body while pressing the tack pieces 6 and 6a formed on both sides of the brace 7. The degree of polarization at the lower end of the connection port 8 is also different when the catcher P of the presser pieces 6 and 6a is bitten by the jaw of the square hole 12. The malleable rubber (2) (2a) is to be fixed as a state securely grounded to the copper film (10) (10a) of the flexible PCB (9).
이와같이된 본 고안은 접속구만 키보드 본체의 상면판에 뚫어놓은 사각구멍에 끼워물림시켜주게되면 접속구의 하단부에 형성된 극성이 다른 도전성 고무의 탄성과 넓은 면적이 연성 PCB 동막에 양호하게 안전하게 접점되는 것이므로 키보드를 이동하더라도 흔들림으로 인하여 연성 PCB가 손상되거나 접점불량 상태가 발생될 염려가 없는 것이며 경우에 따라 LED를 교체하고자할때에는 접속구의 양측에 형성한 압지편만 눌러주면서 잡아당겨주게되면 압지편의 걸림턱이 사각구멍에서 해방되어 쉽게 빼어낼 수 있는 것이므로 접속구를 끼우고 빼기가 용이하여사용이 간편한 잇점이 있는 것이다.In this way, when the connector is inserted into the square hole drilled into the upper plate of the keyboard body, the elasticity and the large area of the conductive rubber having different polarities formed at the lower end of the connector are in good contact with the flexible PCB copper film. There is no risk of damaging the flexible PCB or bad contact due to shaking even if you move it. In some cases, when replacing the LED, if you pull the paper while pressing only the paper pieces formed on both sides of the connector, Since it is freed from the hole and can be easily pulled out, it is easy to use as it is easy to insert and remove the connector.
