And an external conductor cell assembled to the outside of the insulating housing and having an open portion exposing the insulating housing at an upper end thereof.

상기 외부도체셀에는 절연하우징이 슬라이드방식으로 끼워져 외부단자가 핀홀에 끼워지는 외력에 의해 절연하우징이 외부도체셀로부터 분리될 우려가 있고, 이로 인해 회로기판에 접속된 단자가 단락될 수 있는 문제점이 있었다.There is a concern that the insulating housing is inserted into the outer conductor cell in a sliding manner, and the insulating housing is separated from the outer conductor cell by an external force in which the external terminal is fitted into the pinhole, which may short-circuit the terminal connected to the circuit board. there was.

When the external terminal is connected to the switch mechanism, the electronic circuit of the circuit board on which the switch mechanism is mounted is electrically connected to an electronic device (eg, a tester) connected to the external terminal.

상기 스위치기구는, 상기 절연하우징(10)의 핀홀(12)에 고정되어 구비되는 고정단자(21)와, 상기 절연하우징(10)의 핀홀(12)로 삽입되는 외부단자를 탄성적으로 지지하는 스프링단자(22)로 구성된다.The switch mechanism may elastically support the fixed terminal 21 fixed to the pinhole 12 of the insulating housing 10 and the external terminal inserted into the pinhole 12 of the insulating housing 10. It is composed of a spring terminal 22.

상기 고정단자(21)는 일단이 상기 절연하우징(10)의 외부로 노출되어 회로기판의 일측에 접속되고, 타단은 상기 절연하우징(10)의 내부에서 스프링단자(22)와 접속가능하게 구비된다. One end of the fixed terminal 21 is exposed to the outside of the insulating housing 10 so as to be connected to one side of the circuit board, and the other end of the fixed terminal 21 is connected to the spring terminal 22 inside the insulating housing 10. .

상기 스프링단자(22)는 핀홀(12)의 내부에서 상기 고정단자(21)를 탄성적으로 지지하도록 구비되고, 일단이 상기 절연하우징(10)의 외부로 노출되어 회로기판의 일측에 결합되어 있다.The spring terminal 22 is provided to elastically support the fixed terminal 21 in the pinhole 12, one end is exposed to the outside of the insulating housing 10 is coupled to one side of the circuit board. .

상기 외부도체셀(30)은 전기도체로 외부 전자기기의 단자가 접촉되면 회로기판과 외부 전자기기를 전기적으로 접속시키게 된다.The external conductor cell 30 electrically connects the circuit board and the external electronic device when the terminal of the external electronic device is in contact with the electrical conductor.

상기 외부도체셀(30)은 상기 절연하우징(10)이 끼워지는 결합홈(31)을 구비하고, 회로기판에 안착되는 복수개의 지지다리(32)를 돌출되게 구비하며, 외부단자가 출입하는 연결부(33)를 구비하고 있다.The outer conductor cell 30 has a coupling groove 31 into which the insulating housing 10 is fitted, and has a plurality of supporting legs 32 projected on the circuit board to protrude, and a connection portion to which an external terminal enters and exits. 33 is provided.

또한, 상기 외부도체셀(30)의 일측에는 상기 결합홈(31)을 형성하는 1쌍의 결합벽(34)이 서로 소정간격을 두고 형성되어 있다.In addition, a pair of coupling walls 34 forming the coupling grooves 31 are formed at one side of the outer conductor cell 30 with a predetermined distance from each other.

상기 각각의 결합벽(34)의 외측에는 코킹홈(35)이 형성되어 있다. Caulking grooves 35 are formed on the outer side of the respective coupling walls 34.

상기 절연하우징(10)은 절연체인 합성수지로 성형되고, 상기 외부도체셀(30)은 스테인레스 스틸로 사출성형된다. 상기 외부도체셀(30)은 사출성형되므로 결합벽(34)의 외측에 코킹홈(35)이 용이하게 형성될 수 있게 된다. The insulating housing 10 is formed of synthetic resin, which is an insulator, and the outer conductor cell 30 is injection molded of stainless steel. Since the outer conductor cell 30 is injection molded, the caulking groove 35 may be easily formed on the outer side of the coupling wall 34.

상기 코킹홈(35)이 결합벽(34)에 함입되어 형성됨으로써 코킹홈(35)이 형성된 부분에서 결합벽(34)의 두께가 얇아지게 되므로 코킹(caulking) 공정에 의해 용이하게 변형될 수 있게 된다. 즉, 상기 결합홈(31)에 절연하우징(10)이 끼워진 상태에서 상기 코킹홈(35)의 내측벽에 외력을 가하여 코킹공정을 수행하게 되면 코킹홈(35)이 형성된 부분에서 결합벽(34)이 절연하우징(10)쪽으로 돌출되게 변형되면서 절연하우징(10)의 외측면을 물어 잡게 된다.Since the caulking groove 35 is formed by being embedded in the coupling wall 34, the thickness of the coupling wall 34 is thinned at the portion where the caulking groove 35 is formed so that the caulking groove 35 can be easily deformed by a caulking process. do. That is, when the coking process is performed by applying an external force to the inner wall of the caulking groove 35 while the insulating housing 10 is fitted to the coupling groove 31, the coupling wall 34 is formed at the portion where the caulking groove 35 is formed. ) Is deformed to protrude toward the insulating housing (10) to grab the outer surface of the insulating housing (10).

따라서, 코킹공정에 의해 결합벽(34)이 절연하우징(10)을 견고하게 지지할 수 있게 되는 것이다.Therefore, the coupling wall 34 can firmly support the insulating housing 10 by the caulking process.

도 5를 참조하여 본 발명에 의한 RF스위치를 구비한 동축커넥터 제조방법을 설명한다.Referring to Figure 5 will be described a method of manufacturing a coaxial connector having an RF switch according to the present invention.

먼저, 외부도체셀(30)을 사출성형한다. 이때, 외부도체셀(30)의 일측에 코킹홈(35)이 형성되도록 금형을 제조한다. 외부도체셀(30)의 소재는 스테인레스 스틸로 한다.First, the outer conductor cell 30 is injection molded. At this time, the mold is manufactured so that the caulking groove 35 is formed on one side of the outer conductor cell 30. The material of the outer conductor cell 30 is made of stainless steel.

사출성형공정에서 금형으로부터 외부도체셀(30)을 탈거한 이후에는 룰렛(Roulette) 공정에 의해 외부도체셀(30)의 연결부(33)의 형상을 보완한다.After removing the outer conductor cell 30 from the mold in the injection molding process, the shape of the connecting portion 33 of the outer conductor cell 30 is supplemented by a roulette process.

즉, 도 3에 도시된 바와 같이, 상기 외부도체셀(30)의 연결부(33)는 원통형상으로 형성되는데, 사출성형을 하게 되면 연결부(33)의 외표면이 완전한 원형을 이루지 못하게 되므로 룰렛공정에 의해 외표면을 매끄럽게 가공하게 된다.That is, as shown in Figure 3, the connecting portion 33 of the outer conductor cell 30 is formed in a cylindrical shape, when the injection molding the outer surface of the connecting portion 33 does not form a complete circle, so roulette process This makes the outer surface smooth.

또한, 외부도체셀(30)의 지지다리(32)들은 사출성형시나 사출성형후에 서로 벌어질 수 있는데, 이는 지그나 형틀에 지지다리(32)를 강제진입시켜 형상을 교정하게 된다.In addition, the support legs 32 of the outer conductor cell 30 may be separated from each other at the time of injection molding or after injection molding. This is to force the support legs 32 into the jig or the mold to correct the shape.

외부도체셀(30)의 형상을 보정한 이후에 외부도체셀(30)에 절연하우징(10)을 끼워 결합시킨다.After correcting the shape of the outer conductor cell 30, the insulating housing 10 is fitted to the outer conductor cell 30 to be coupled.

외부도체셀(30)에 절연하우징(10)을 결합시킨 후 외부도체셀(30)의 코킹홈(35)에 외력을 가하여 코킹공정을 수행한다.After the insulating housing 10 is coupled to the outer conductor cell 30, the caulking process is performed by applying an external force to the caulking groove 35 of the outer conductor cell 30.

즉, 절연하우징(10)을 사이에 두고 서로 반대쪽에 위치하는 1쌍의 코킹홈(35)에 동시에 외력을 가해 결합벽(34)의 내측부분이 절연하우징(10)의 외측을 견고하게 지지하도록 한다.That is, external force is simultaneously applied to a pair of caulking grooves 35 positioned opposite to each other with the insulating housing 10 interposed therebetween so that the inner portion of the coupling wall 34 firmly supports the outside of the insulating housing 10. do.

이상에서 설명한 바와 같이 본 발명에 따른 RF스위치를 구비한 동축커넥터에 의하면, 외부도체셀이 스텐인레스 스틸 재질로 제조되므로 내마모성이 향상되고, 사출성형에 의해 제조되므로 코킹홈을 용이하게 형성할 수 있으며, 코킹조립에 의해 절연하우징과 외부도체셀이 견고하게 결합될 수 있는 효과가 있다.As described above, according to the coaxial connector having the RF switch according to the present invention, since the outer conductor cell is made of stainless steel, the wear resistance is improved and manufactured by injection molding, so that the caulking groove can be easily formed. By caulking assembly, there is an effect that the insulating housing and the outer conductor cell can be firmly coupled.
