본 발명은 LED(light emitting diode)를 회로기판에 접속시키고자 할 때 LED의 (+)(-)돌출단자를 회로기판의 접속단자에 꽂아주는 단순 작업만으로도 LED를 회로기판에 접속시킬 수 있도록 개선된 납땜없이 회로기판에 접속시킬 수 있는 LED에 관한 것이다.The present invention is improved to connect the LED to the circuit board by simply plugging the (+) (-) projection terminal of the LED into the connection terminal of the circuit board when the LED (light emitting diode) to connect to the circuit board The present invention relates to an LED that can be connected to a circuit board without soldering.

통상 LED는 수 와트에서부터 수십 와트의 낮은 소비전력으로 백색·적색·청색 등 여러 가지 색상의 광출력을 얻을 수 있으므로서 문자나 숫자표시를 식별할 수 있도록 하는 전자광고판을 비롯하여 상품을 진열하는 진열장 등을 조명하는 조명장치에 다양하게 적용되고 있다.In general, LEDs can obtain light output of various colors such as white, red, and blue with low power consumption of several watts to several tens of watts, and an electronic billboard for identifying letters and numbers, as well as a showcase for displaying products. Various applications have been applied to lighting devices.

기존의 LED는 전기회로가 인쇄된 회로기판에 형성된 접속단자에 (+)(-)돌출단자를 꽂아준 다음 회로기판의 이면측으로 돌출된 (+)(-)돌출단자를 납땜하는 방법으로 LED를 회로기판에 접속시키고 있는바, 이와 같이 LED의 (+)(-)돌출단자를 회로기판에 납땜하는 방법으로 접속시켜서 전자광고판이나 조명장치로 사용하는 도중에 다수의 LED들 중 하나 또는 그 이상의 LED가 점등되지 않는 고장을 일으켰을 때 그 고장난 LED로 인하여 전자광고판의 문자나 숫자가 정확하게 표현되지 않거나 또는 조명효과가 떨어지는 문제가 발생된다.Existing LED is connected by connecting (+) (-) projecting terminal to the connection terminal formed on the printed circuit board and then soldering the (+) (-) projecting terminal protruding to the back side of the circuit board. In this way, by connecting the positive (+) (-) projecting terminal of the LED to the circuit board by soldering the circuit board, one or more of the LEDs during the use as an electronic billboard or lighting device When the failure does not turn on due to the broken LED due to the letter or number of the electronic billboard is not accurately represented or the lighting effect is reduced.

따라서 LED를 이용한 전자광고판이나 조명장치를 사용하는 도중에 점등이 않되는 LED는 새것으로 교체해주어야만 광고효과 또는 조명효과를 높일 수 있는데, 기존의 LED들은 (+)(-)돌출단자를 회로기판에 납땜으로 접속시켰기 때문에 고장난 LED를 회로기판에서 분리시키고 새것으로 교체자 할 때에는 많은 시간이 소요되는 등 여러가지 문제가 있다.Therefore, LEDs that do not light up while using LED or electronic billboards or LED lighting devices must be replaced with new ones to increase the advertising effect or lighting effect. Existing LEDs have positive (+) projection terminals on the circuit board. Because of the connection by soldering, there are various problems such as taking a long time when removing the failed LED from the circuit board and replacing it with a new one.

예를 들어, 무수히 많은 LED들이 종횡으로 다수열 설치되어 있는 전자광고판의 경우에는 LED의 몸체가 표출되어 있는 광고판의 전면에서 점등되지 않는 LED만을 골라내어 빼내는 작업으로 LED를 분리시킬 수는 없었기 때문에 작업자는 광고판 이면에서 고장난 LED의 (+)(-)돌출단자를 접속시키고 있는 납땜부분을 절단 제거하거나 또는 납땜부분을 전기인두 등으로 가열하여 납땜을 녹여주는 작업으로 고장난 LED를 회로기판에서 분리시킬 수 있는데, 전자광고판의 이면측에서 고장난 LED를 찾아내는데에는 많은 시간이 소요되며, 또한 고장난 LED를 찾은 후 납땜부분을 제거함에 있어 니퍼(nipper) 등의 수공구를 사용하여 절단할 때에는 회로기판에 인쇄된 전기회로가 손상되지 않도록 조심하여야 하며, 또는 전기인두로 납땜부분을 녹여줄 때에는 용융되는 납땜이 이웃하는 (+)(-)돌출단자 또는 회로기판의 접속단자 등에 옮겨붙지 않도록 조심해야 하는 관계로 고장난 LED를 분리하는데 많은 시간과 수고가 뒤따르게 되며,For example, in the case of an electronic billboard with a large number of LEDs installed vertically and horizontally, the worker could not separate the LEDs by selecting and removing only the LEDs that are not lit from the front of the billboard where the body of the LED is displayed. Is to cut and remove the solder part connecting the (+) (-) projecting terminal of the failed LED on the back of the billboard or to melt the solder by heating the solder part with an electric iron etc. to separate the failed LED from the circuit board. It takes a lot of time to find the faulty LED on the back side of the electronic billboard. Also, when cutting by using a hand tool such as a nipper to remove the soldered part after finding the faulty LED, it is printed on the circuit board. Care must be taken not to damage the circuit, or the solder that melts when the solder is melted with an electric iron It takes a lot of time and effort to separate the failed LED because care must be taken not to stick to the neighboring (+) (-) protruding terminal or the connection terminal of the circuit board.

또한 조명장치의 경우에도 케이스 등에 장착되어 있는 회로기판을 빼내야만 고장난 LED를 교체할 수 있기 때문에 회로기판을 빼내고, 또 LED의 (+)(-)돌출단자를 고정상태로 접속시키고 있는 납땜부분을 제거하는데 시간이 소요되고, 또 고장난 LED를 새것으로 교체한 후 회로기판을 다시 케이스에 장착하는데에도 시간이 소요되므로 조명장치 역시 고장난 LED를 새것으로 교체하는데 많은 시간과 수고가 뒤따르게 된다.Also, in the case of lighting devices, the broken LEDs can be replaced only by removing the circuit boards mounted on the case, so the circuit boards can be removed and the soldered part connecting the positive (+) projecting terminals of the LEDs in a fixed state can be It takes time to remove, and it takes time to replace the failed LED with new one and then to refit the circuit board to the case, so the lighting device also takes a lot of time and effort to replace the failed LED with new one.

본 발명은 상기와 같이 회로기판에 LED를 납땜으로 접속시키는데 나타나는 제반 문제를 해결하기 위하여 제안된 것으로, LED의 (+)(-)돌출단자를 회로기판에 형성된 접속단자에 꽂아준 다음 납땜하지 않고도 LED를 회로기판의 접속단자에 견고한 상태로 접속시킬 수 있으며, 또한 고장난 LED를 회로기판에서 분리시키고자 할 때에는 회로기판의 일면으로 노출되어 있는 LED의 몸체를 손가락으로 잡고 (+)(-)돌출단자를 접속단자에서 빼낼 수 있도록 하므로서 고장난 LED의 교체작업을 용이하고 신속하게 수행할 수 있도록 하는데 목적을 두고 발명한 것이다.The present invention has been proposed to solve various problems in soldering an LED to a circuit board as described above, without plugging the (+) (-) protruding terminal of the LED into the connection terminal formed on the circuit board and then soldering it. The LED can be connected to the connection terminal of the circuit board in a solid state, and in order to separate the failed LED from the circuit board, hold the body of the LED exposed to one side of the circuit board with a finger and protrude (+) (-).

(13a) (14a) There is an embodiment formed of projections 32 and 33 protruding in pairs or plural pairs symmetrically at each end, and each embodiment of the interference fitting means 3 will be described together with the drawings. Let's do it.

먼저, 도 1 내지 도 4의 도시는 LED(1)의 빛투과부(12)가 오목렌즈타입으로 형성되어 있고, (+)돌출단자(13)에만 차단부(15)가 형성되어 있으며, 상기 억지끼움수단(3)은 LED(1)의 (+)(-)돌출단자(13)(14)의 삽입단(13a)(14a) 각각에 돌출되게 절곡 형성된 밴딩돌기(31)로 구성하여서 된 것을 실시예로 하고 있다.First, as shown in FIGS. 1 to 4, the light transmitting part 12 of the LED 1 is formed in a concave lens type, and the blocking part 15 is formed only in the positive protruding terminal 13, and the interference is prevented. The fitting means 3 is composed of a bending protrusion 31 bent to protrude to each of the insertion end 13a, 14a of the (+) (-) protrusion terminal 13, 14 of the LED (1). It is set as an Example.

상기한 실시예에서의 밴딩돌기(31)는 LED를 제조하기 전에 (+)(-)돌출단자(13)(14)의 소재가 되는 금속판재(알루미늄판재 등)에서 펀칭가공할 때 삽입단(13a)(14a)이 되는 부분을 밴딩가공하여 일측으로 돌출되게 절곡시켜서 형성되게 하는 것이다. 따라서 LED(1)를 제조하였을 때에는 몸체(11)의 저부측으로 일정길이 돌출되게 형성되는 (+)(-)돌출단자(13)(14)의 삽입단(13a)(14a) 각각에는 일측으로 돌출된 밴딩돌기(31)가 억지끼움수단(3)을 형성하게 된다.The banding protrusion 31 in the above-described embodiment is inserted at the end of the punching process from a metal plate (aluminum plate, etc.), which is a material of the (+) (-) protrusion terminals 13 and 14, before manufacturing the LED. 13a) 14a is to be formed by bending the portion to be protruded to one side by bending.
