특히, 상기 도체(322b)의 일단은 반구형태를 이루고 있으며, 앞서 언급한 암부재(321)의 반원홈(321b-1)에 삽입되어 회전가능하게 면 접촉된다.Particularly, one end of the conductor 322b has a hemispherical shape, and is inserted into the semicircular groove 321b-1 of the arm member 321 mentioned above to be in surface contact with the rotatable surface.

참고로, 상기 회전체(322a)와 도체(322b)를 제조하는 방식은 개별적으로 제조된 것을 상호 결합하거나 또는 회전체(322a)와 도체(322b)를 인서트성형을 통해 제조할 수 있다.
For reference, the method of manufacturing the rotating body 322a and the conductor 322b may be manufactured by combining the manufactured separately, or by insert molding the rotating body 322a and the conductor 322b.

상기 탄성체(330)는 공지의 코일스프링으로서, 본 실시 예의 경우 하우징(310)의 수용부(311a,312a)에 내설되어 암부재(321)의 이동체(321a)를 수부재(322)를 향해 일 방향으로 탄발지지하는 기능을 한다.
The elastic body 330 is a known coil spring, and in the present embodiment, the elastic body 330 is installed in the receiving portions 311a and 312a of the housing 310 to move the movable body 321a of the female member 321 toward the male member 322. It acts to support the shot in the direction.

상기와 같은 구성으로 이루어진 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made of the above configuration as follows.

우선, 지중전선(L1)과 배전선(L2)을 지중전선커넥터(300)에 설치하는 과정을 간략하게 설명하면, 지지플레이트(100) 상에 고정된 지중전선커넥터(300)를 구성하는 암부재(321)의 전선고정부(321a-1)에는 지중전선(L1)을 압입시켜 준 상태에서 결속부재(T)를 매개로 단단하게 2차 고정시켜 주고, 수부재(322)의 전선고정부(322a-1)에는 배전선(L2)을 압입시켜 준 상태에서 결속부재(T)을 매개로 단단하게 2차 고정시켜 주면 된다.
First, the process of installing the underground wire L1 and the distribution line L2 to the underground wire connector 300 will be described briefly, and the arm member constituting the underground wire connector 300 fixed on the support plate 100 ( In the wire fixing part 321a-1 of 321, the underground wire L1 is press-fitted in the state where the underground wire L1 is press-fitted, and the second fixing is firmly performed through the binding member T, and the wire fixing part 322a of the male member 322 is fixed. In the case of -1), in the state in which the power distribution line L2 is press-fitted, the secondary member can be fixed firmly through the binding member T.

한편, 상기와 같이 설치된 상태에서 지진이 발생하게 되면, 지면이 좌우, 뿐만 아니라 상하로도 심하게 흔들리게 되는데, 이로 인해 지중전선커넥터(300)에 설치된 지중전선(L1) 역시 상하로 진동이 발생하게 된다.On the other hand, when an earthquake occurs in the above-described state, the ground shakes violently up and down, as well as up and down, which causes the underground wire L1 installed in the underground cable connector 300 to also generate vibration up and down. do.

이와 같이, 지진발생으로 인한 상하 진동으로 인해 지중전선(L1)이 하방으로 힘이 가해지게 되면, 이를 받침대(1-1)와 지지플레이트(100) 사이에 배치된 완충스프링(200)이 압축 및 복원을 반복하면서 진동을 흡수하게 되며, 이로 인하여 지중전선(L1)에 가해지던 힘은 완충스프링(200)에 의해 힘이 상쇄 또는 감쇄되어 반복적인 상하진동으로 인해 지중전선(L1)이 단선되는 것을 방지할 수 있게 된다.
As such, when the underground wire L1 is applied downward due to the up and down vibration caused by the earthquake, the buffer spring 200 disposed between the pedestal 1-1 and the support plate 100 is compressed and The vibration is absorbed while repeating the restoration, and the force applied to the underground wire L1 is canceled or attenuated by the buffer spring 200 so that the underground wire L1 is disconnected due to the repeated vertical vibration. It can be prevented.

본 발명은 기재된 구체적인 실시 예에 대해서만 상세히 설명되었지만 본 발명의 기술사상범위 내에서 다양하게 변형 및 수정할 수 있음은 당업자에 있어서 당연한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연한 것이다.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
