이 고안은 가변저항기에의 노브 결합장치에 관한 것으로서, 보다 상세하게는 노브내주면에 복수의 압입돌기를 축방향으로 형성하므로써 부품수가 줄어들고 조립이 간편하여 생산성 향상에 기여할수 있도록 한 가변저항기의 노브 결합장치에 관한 것이다.This invention relates to a knob coupling device for a variable resistor, and more particularly, by forming a plurality of indentation protrusions on the inner circumferential surface of the knob in an axial direction, the number of parts is reduced, and the assembly of the variable resistor knob contributes to productivity improvement by simplifying assembly. Relates to a device.

일반적으로, 각종 전자 전기제품에 사용되는 가변저항기는 제1도에 나타낸 바와같이 선단에 걸림평면(11)이 형성된 가변축 (12)이 몸체(13)로부터 회동가능케 연장설치되어 있으며, 이 가변축(12)에는 외면에 띠형돌기(14)가 형성되고 축방향으로 절결홈(15)이 형성되어 탄성력있게 형성된 디(D)형의 샤프트 플레이트 (16)가 삽입결합되어 있다.In general, the variable resistor used in various electronic and electrical appliances has a variable shaft 12 having a locking plane 11 formed at its tip as shown in FIG. 1 extending from the body 13 so as to be rotatable. In the 12, a strip-shaped protrusion 14 is formed on the outer surface, and a notched groove 15 is formed in the axial direction, and the D-shaped shaft plate 16, which is formed elastically, is inserted and coupled thereto.

상기 샤프트 플레이트(16)가 삽입결합된 가변축(12)의 외면에는, 원형내홈(21)이 형성된 노브(20)가 삽입되어 있다.A knob 20 having a circular inner groove 21 is inserted into an outer surface of the variable shaft 12 to which the shaft plate 16 is inserted and coupled.

상기와 같은 가변저항기의 노브 결합장치는, 노브(20)의 원형내홈(21)에 샤프트 플레이트(16)를 절반정도 조립한 후 가변저항기의 가변축(12)에 가조립하되 샤프트 플레이트(16)의 절결홈(15) 부분이 가변축(12)의 걸림평면(11)과 접촉되도록 하여 밀어 넣으면 가변축(12)의 외면이 샤프트 플레이트(16)의 띠형돌기(14)를 외측으로 밀어 벌림으로써 상기 가변축(12)에 노브(20)가 견고하게 결합고정된다.The knob coupling device of the variable resistor as described above is assembled to the variable shaft 12 of the variable resistor after half assembling the shaft plate 16 in the circular inner groove 21 of the knob 20, but of the shaft plate 16 When the notched groove 15 is pushed in contact with the engaging plane 11 of the variable shaft 12, the outer surface of the variable shaft 12 pushes the band-shaped protrusion 14 of the shaft plate 16 outward to open the above. The knob 20 is firmly coupled to the variable shaft 12.

그러나, 상기와 같은 가변저항기에의 노브 결합장치에 있어서는 노브(20)의 원형내홈(21)에 샤프트 플레이트(16)를 절반정도 삽입하여야만 노브(20)가 조립됨으로써 조립작업이 어렵고 난해하며, 필수적으로 샤프트 플레이트(16)가 소요됨으로써 부품수의 증가로 인한 원가상승이 이루어지는 문제점을 갖고 있었다.However, in the knob coupling device to the variable resistor as described above, the shaft 20 is inserted only halfway into the circular groove 21 of the knob 20 so that the assembly of the knob 20 is difficult and difficult. As a result, the shaft plate 16 has a problem in that cost increases due to an increase in the number of parts.

이 고안은 상기와 같은 종래의 제반 문제점을 해결하기 위한 것으로서, 이 고안의 목적은, 노브내주면에 복수의압입돌기를 축방향으로 형성함으로써 부품수가 줄어들고 조립이 간편하여 생산성 향상에 기여할 수 있도록 한 가변저항기의 노브 결합장치를 제공하는데 있다.This invention is to solve the above-mentioned conventional problems, the object of this invention is to form a plurality of indentation protrusions on the inner circumference of the knob in the axial direction, the number of parts is reduced, the assembly is easy to assemble the variable to contribute to productivity improvement It is to provide a knob coupling device of the resistor.

상기와 같은 목적을 달성하기 위한 이 고안에 따른 가변저항기의 노브 결합장치의 특징은, 선단에 걸림평면이 형성된 가변축이 몸체로부터 회동가능케 연장설치되고 이 가변축에 노브가 삽입결합되는 가변저항기에의 노브 결합장치에 있어서, 상기 노브의 내면에 가변축과 직접적으로 압입결합되는 압입돌기가 축방향으로 돌출형성되어 있는 점에 있다.A feature of the knob coupling device of the variable resistor according to the present invention for achieving the above object is that the variable shaft having a locking plane formed at the front end is rotatably extended from the body and the variable resistor is inserted into the variable shaft knob In the knob coupling device of the present invention, the indentation projection which is press-fitted directly to the variable shaft on the inner surface of the knob is protruding in the axial direction.

이하, 이 고안에 따른 가변저항기의 노브 결합장치를 일실시예의 첨부도면에 의하여 상세히 설명한다.Hereinafter, the knob coupling device of the variable resistor according to the present invention will be described in detail by the accompanying drawings of an embodiment.

제2도는 이 고안에 따른 가변저항기에의 노브 결합장치를 설명하기 위해 나타낸 도면이다.2 is a view for explaining a knob coupling device to a variable resistor according to the present invention.

여기에서, 가변저항기는 선단에 걸림평면(11)이 형성된 가변축(12)이 몸체(13)로부터 회동가능케 연장설치되어 있고, 상기 가변축(12)에 삽입되는 노브(20)는 걸림평면(22)이 형성된 내면에 축방향으로 복수의 압입돌기(23)가 돌출형성되어 있다.Here, the variable resistor is provided with a variable shaft (12) having a locking plane (11) formed at the front end thereof so as to be rotatable from the body (13), and the knob (20) inserted into the variable shaft (12) has a locking plane ( A plurality of indentation protrusions 23 protrude in the axial direction on the inner surface on which 22 is formed.

상기와 같이 구성된 이 고안에 다른 가변저항기에의 노브 결합장치는, 몸체(13)로부터 연장설치된 가변축(12)에 노브(20)를 직접조립하되 가변축(12) 및 노브(20)의 걸림평면(11),(22)이 서로 접촉되게 밀어 넣으면 노브(20) 내면의 압입돌기(2)3가 가변축(12)의 외면에 압착되어 억지끼워맞춤이 이루어지게 된다.The knob coupling device to the variable resistor according to the present invention configured as described above, the knob 20 is assembled directly to the variable shaft 12 extending from the body 13, but the locking of the variable shaft 12 and the knob 20 When the planes 11 and 22 are pushed into contact with each other, the indentation protrusions 2 and 3 of the inner surface of the knob 20 are pressed against the outer surface of the variable shaft 12 to be fitted with interference.

그러므로, 이 고안에 따른 가변저항기에의 노브 결합장치는 가변축(12)의 외면에 직접적으로 노브(20) 내주면의 압입돌기(23)가 압착되어 삽입결합되기 때문에 종래고안의 필수구성 요소인 샤프트 플레이트(16)가 필요하지 않아 부품수가 줄어들고 조립이 간편하며, 이에 따라서 생산성 향상에 기여할수 있게 된다.Therefore, the knob coupling device for the variable resistor according to the present invention is a shaft which is an essential component of the conventional design because the press-fitting protrusion 23 of the inner peripheral surface of the knob 20 is pressed and inserted directly to the outer surface of the variable shaft 12. Since the plate 16 is not required, the number of parts is reduced and assembly is easy, thus contributing to productivity improvement.

이상에서와 같이 이 고안에 따른 가변저항기에의 노브 결합장치에 의하면, 가변저항기의 가변축에 삽입되는 노브내주면에 복수의 압입돌기가 축방향으로 형성되어 있기 때문에 부품수가 줄어들고 조립이 간편하여 생산성 향상에 기여할 수 있는 효과가 있다.As described above, according to the knob coupling device of the variable resistor according to the present invention, since a plurality of indentation protrusions are formed in the axial direction on the inner circumferential surface of the knob inserted into the variable shaft of the variable resistor, the number of parts is reduced and assembly is simple, thereby improving productivity. There is an effect that can contribute to.
