이과 같은 본 고안의 작용은 다음과 같다.The operation of the present invention as described above is as follows.
제3도에 도시된 바와 같이, 본 고안에 따른 이어폰의 절선방지구조가 이어폰(20)의 신호전송선(22) 상에 끼워져 설치된 상태에서 사용도중에 강한 외력이 접속단자(30)와 하우징(36) 사이에 해당하는 신호전송선(22)상에 가해지면, 제4도에 도시된 바와 같이, 그 신호전송선(22)이 외력에 의해 당겨짐에 따라 하우징(36) 내부의 신호전송선수납실(28)내에 권회된 상태로 수납되는 신호전송선(22)과 고정된 상태의 이송원판(38)이 작동실(32) 내부에서 접속단자(30)쪽으로 당겨져 스프링(40)을 압축시키고, 그 결과 신호전송선수납실(28) 내부의 신호전송선(22)이 권회된 상태로부터 신장되면서 당겨지게 되어 접속단자(30)와 연결된 신호전송선(22)의 끊어짐이 방지된다.As shown in FIG. 3, a strong external force during use in the state where the cutting line preventing structure of the earphone according to the present invention is fitted on the signal transmission line 22 of the earphone 20 is connected to the connection terminal 30 and the housing 36. When applied on the signal transmission line 22 corresponding to the above, as shown in FIG. 4, the signal transmission line 22 in the signal transmission bow storage room 28 inside the housing 36 is pulled by the external force. The signal transmission line 22 accommodated in the wound state and the transfer disk 38 in the fixed state are pulled toward the connection terminal 30 in the operating chamber 32 to compress the spring 40, and as a result, the signal transmission bow storage room (28) The signal transmission line 22 inside is pulled while being stretched from the wound state, thereby preventing the signal transmission line 22 connected to the connection terminal 30 from being cut off.
이상태로부터 신호전송선(22)에 작용되던 외력이 제거되면 하우징(36) 내부의 신호전송선(22)과 고정결합된 이송원판(38)이 스프링(40)의 복원력에 의해 원래위치로 복귀됨과 동시에 하우징(36) 외측으로 신장되었던 신호전송선(22)이 하우징(36)내부에 신호전송선수납실(28)내로 다시 수납되면서 권회된다.When the external force acting on the signal transmission line 22 is removed from this state, the transfer disk 38 fixedly coupled to the signal transmission line 22 inside the housing 36 returns to its original position by the restoring force of the spring 40 and at the same time the housing (36) The signal transmission line 22, which has been extended outward, is wound while being received back into the signal transmission bow storage 28 inside the housing 36.
이와 같은 본 고안을 적용하면 이어폰에서 접속단자와 하우징 사이에 해당되는 신호전송선 사이에 외부의 당김힘이 작용하는 경우에 하우징 내부의 신호전송선수납실내에 수납되어 있던 권회된 상태의 신호전송선이 그 작용힘의 세기에 따라 적절한 길이로 신장되므로 신호전송선이 끊어지는 것을 방지할 수 있다는 효과가 있으며, 외력이 제거되면 스프링의 복원력에 의해 하우징 외로부 신장되었다. 신호전송선이 다시 수납되므로 그 사용이 매우 간편하다는 효과가 있다.According to the present invention, when the external pull force is applied between the signal transmission line between the connection terminal and the housing in the earphone, the wound signal transmission line stored in the signal transmission bow storage inside the housing is operated. Since it is extended to the appropriate length according to the strength of the force, there is an effect that it is possible to prevent the signal transmission line from being broken. Since the signal transmission line is stored again, the effect is very simple.
