본 고안은 회전형 가변 저항기 및 콘덴서, 스위치등과 같은 전기부품의 단자 구조에 관한 것으로 특히 프린트 배선에 적합한 것을 제공하고저 하는 것이다. 이하 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention relates to a terminal structure of an electrical component such as a rotary variable resistor, a capacitor, a switch, and the like, and particularly provides a suitable one for printed wiring. Hereinafter will be described in detail based on the accompanying drawings.
절연재로 형성된 상자형 케이스(1)내에 나사부(2a)와 괘지륜(2b)을 유삽시킨 금속제의 축(2)을 케이스(1)의 전후벽(1a),(1b) 사이에 넣고 저항체(5)와 절연기판(3)을 취부판(4)상에 리벳트(6)로서 고착시켜 케이스(1)의 개방면을 밀폐시키되 U자형 탄성 금속제된 된 습동자(7)를 축(2)과 나합하여 축(2)의 회전에 의해 이동하여 저항체(5)상에 습접(接)되게한 것이며 (8)은 본 고안에 관련된 탄성 금속제로 된 단자부(8a) 평면부(8b) 및 축(2)을 삽입용 절결부(8c)가 형성된 탄성부(8d)로 구성된 것으로 단자부(8a)에는 길이 방향으로 V자상의 리브(rib)(8e)가, 또한 평면부(8b)에는 단자(8)가 축(2)에 접촉하는 부분과 단자부(8a)와의 사이에 단자부(8a)의 폭보다 약간 넓은 폭의 凸부(8f)가 형성되어 있다.In the box-shaped case 1 formed of an insulating material, a metal shaft 2 into which the screw portion 2a and the wheel ring 2b are inserted is inserted between the front and rear walls 1a and 1b of the case 1, and the resistor 5 ) And the insulating board 3 are fixed to the mounting plate 4 as rivets 6 to seal the open surface of the case 1, while the U-shaped elastic metal-made slider 7 Screwed together and moved by rotation of the shaft 2 to be wetted on the resistor 5 ( (8) is composed of a terminal portion (8a) made of elastic metal according to the present invention, a planar portion (8b) and an elastic portion (8d) having a cutout portion (8c) for inserting the shaft (2). In the 8a, the V-shaped ribs 8e in the longitudinal direction, and in the planar portion 8b, the terminal 8a is between the terminal portion 8a and the portion where the terminal 8 contacts the shaft 2. 8f of the width | variety which is slightly wider than the width | variety of () is formed.
그리고 단자(8)가 케이스(1)내에 삽입될때에는 절결구(8c) 내에 축(2)의 일부가 위치함과 동시에 탄성부(8d)의 탄성에 의해 평면부(8b)과 괘지륜(2b)과 접촉하여 축(2)을 후벽(1b)에 탄압하고 또한 단자부(8a)는 절연기판(3)의 구멍(3a)으로부터 외방으로 돌출하며, 단자부(8a)에 형성된 리브(8e)의 종단은 절연기판(3)면에서 약간 떨어진 위치에 있다.When the terminal 8 is inserted into the case 1, a part of the shaft 2 is located in the cutout 8c, and the flat portion 8b and the wheel 2b are supported by the elasticity of the elastic portion 8d. ), The shaft 2 is pressed against the rear wall 1b, and the terminal portion 8a protrudes outward from the hole 3a of the insulating substrate 3, and terminates the rib 8e formed in the terminal portion 8a. Is located slightly away from the insulating substrate 3 surface.
이와 같이 구성된 본 고안은 프린트기판(도시하지 않음)의 구멍에 단자(8) 및 단자부 리벳트(6)를 삽통하여 납땜에 의해 프린트 기판에 고착되지만 납땜시 모세관 현상에 의한 플럭스(flux)의 상승이 리브(8e)의 종단과 凸부(8f)에 의해 저자되어 플럭스가 단자(8)에 의해 축(2)과의 접촉부까지 상승하지 않도록 되어 있다.The present invention configured as described above is fixed to the printed circuit board by soldering by inserting the terminal 8 and the terminal part rivet 6 into the hole of the printed board (not shown), but raising the flux due to the capillary phenomenon during soldering. The ends of the ribs 8e and the recesses 8f prevent the flux from rising to the contact portion with the shaft 2 by the terminal 8.
이와 같이 된 본 고안의 단자(8)는 단자부(8a)에 리브(8e)를 또 평면부(8b)에 단자부(8a)와 단자(8)의 축(2)에의 접촉부 사이에 凸부(8f)를 설치한 것이기 때문에 납땜시 플럭스가 축 접촉부로 개입하는 것을 저지하므로서 단자(8)와 축(2)과의 접촉상태를 안정 확실하게 할수가 있는 효과를 갖는 것이다.The terminal 8 according to the present invention has a rib 8e at the terminal portion 8a and a flat portion 8f at the flat portion 8b between the terminal portion 8a and the contact portion between the terminal portion 8a and the shaft 2 of the terminal 8. ), Which prevents the flux from interfering with the shaft contact portion during soldering, and has an effect of making the contact state between the terminal 8 and the shaft 2 stable.
