Description
제 1 도는 본 고안장치의 사시도.1 is a perspective view of the present device.
제 2 도는 제 1 도중 (가)에 나타낸 부분의 확대도.2 is an enlarged view of a portion shown in (a) of the first view.
본 고안은 전화 국선에 연결된 전화기를 낙뢰등과 같은 이상 전압이 국선에 인가되었을 때 기기를 보호하기 위한 국선 보안 장치에 관한 것으로서, 특히, 바이메탈편의 중앙부에 넓은 면적부위로 된 원통형 축열부를 설치하고, 축열부내에는 히터를 내장시켜 형성된 국선 보안 장치에 관한 것이다.The present invention relates to a trunk line security device for protecting a device when an abnormal voltage such as a lightning strike is applied to a telephone connected to a telephone trunk line. In particular, a cylindrical heat storage unit having a large area is installed in the center of a bimetal piece. It relates to a trunk line security device formed by embedding a heater in the heat storage unit.
종래의 국선 보안장치는 국선에 연결된 단자편과 접지사이에 아레스터(피뢰기)를 연결하고, 국선사이에 히터선을 설치하며, 히터선은 1자형 바이메탈편에 감아서 국선에 이상전압이 인가되면 히터선의 발열에 의하여 바이메탈편이 접지에 접촉되도록 하는 것으로서 바이메탈편의 휨 동작을 빠르게 일으키기 위하여서는 히터선이 길어져야 되는데 히터선을 길게하여 자체저항값을 크게 하면 국선 전화기 사이의 저항값이 크게 되어 전화국측에서 보면 신호통로가 제한되는 단점이 발생되고, 그렇다고 히터선 길이를 짧게한 상태에서 바이메탈편의 두께를 얇게 하는 경우에는 동작 속도는 필요한 만큼 빠르게 되나 회복속도가 역시 빠르게 되어 국선을 충분한 시간동안 접지상태로 유지하지 못하게 되는 단점이 있었다.The conventional trunk line security device connects an arrester (arrestor) between the terminal piece connected to the trunk line and the ground, installs a heater wire between the trunk lines, and the heater wire is wound around a single-shaped bimetal piece to apply abnormal voltage to the trunk line. As the bimetal piece is brought into contact with the ground by the heating of the heater wire, the heater wire needs to be long in order to cause the bending action of the bimetal piece quickly. When the heater wire is lengthened and the self-resistance value is increased, the resistance value between the trunk lines is increased. In the case of, the disadvantage is that the signal path is limited. However, when the length of the heater wire is shortened and the thickness of the bimetal piece is made thin, the operation speed is as fast as necessary, but the recovery speed is also fast and the trunk line is grounded for a sufficient time. There was a drawback to being unable to maintain.
본 고안은 이러한 종래의 단점을 해결하기 위하여 바이메탈편의 중앙부에 넓은 면적부를 설치하여 한번 감아서 원통형 축열부를 설치하고, 원통형 축열부 내에는 히터를 코일형으로 말아서 내장시켜 히터의 발열을 효과적으로 바이메탈편에 전달 할 수 있어 바이메탈편에 이상 전류가 흐를 경우에 바이메탈의 동작특성을 개선할 수 있고, 충분한 시간동안 접지상태를 유지할 수 있도록 한 국선 보안장치를 제공하는 것을 목적으로 하는 것으로서 이하 첨부된 도면을 참조하면서 본 고안장치를 상세하게 설명하면 다음과 같다.In order to solve the above disadvantages, the present invention installs a cylindrical heat storage unit by winding a wide area at the center of the bimetal piece and winding the heater once in the cylindrical heat storage unit to roll up the heater in a coil shape so that the heat generation of the heater is effectively applied to the bimetal piece. It is possible to improve the operating characteristics of the bimetal when abnormal current flows through the bimetal piece, and to provide a trunk line security device that can maintain the ground state for a sufficient time. While explaining the present invention in detail as follows.
제 1 도에서와 같이 아레스터(1)의 지지단자편(2,2')을 국선(L1,L2) 측 히터선(3,3')을 통하여 내선(T1,T2)측에 연결하고, 아래스터(1)의 접지단자(4)를 접지단자(5)에 연결하며, 바이메탈편(6,6')의 상부측(6A,6A')를 지지단자편(2,2')에 연결하며, 바이메탈편(6,6')의 중앙부에 넓은 면을 형성하여 1회 감아서 된 축열부(7,7')를 형성하고, 축열부(7,7')내에는 히터선(3,3')을 코일형으로 감아서 내장시키며, 바이메탈편(6,6')의 일측단부를 아레스터(1)의 지지단자편(2,2')국선측의 상단측에 고착하고, 바이메탈편(6,6')의 타측단부는 아레스터(1)의 접지단자(4)에 인접하여 위치시키며, 아레스터(1)의 접지단자(4)는 접지단자(5)의 절결홈(5')에 끼워서 된 구성으로서 이러한 본 고안장치의 작용효과를 설명하면 다음과 같다.As shown in FIG. 1, the support terminal pieces 2, 2 'of the arrester 1 are connected to the internal lines T 1 , T 2 through the heater lines 3, 3' on the trunk line L 1 , L 2 side. The ground terminal 4 of the lower stud 1 to the ground terminal 5, and the upper side 6A, 6A 'of the bimetal piece 6, 6' is supported on the support terminal piece 2, 2 '), And forms a wide surface at the center of the bimetal piece 6,6' to form a heat storage unit 7,7 'wound once, and a heater in the heat storage unit 7,7'. The wires 3 and 3 'are coiled and embedded, and one end of the bimetal piece 6 and 6' is fixed to the upper end side of the support terminal piece 2 and 2 'of the arrester 1 side. The other end of the bimetal piece 6, 6 'is positioned adjacent to the ground terminal 4 of the arrester 1, and the ground terminal 4 of the arrester 1 is cut out of the ground terminal 5. Referring to the operation and effect of the present invention as a configuration sandwiched in the groove 5 'as follows.
축열부(7,7')는 바이메탈편(6,6')의 중앙부에 위치하고 있고 히터선(3,3')이 국선(L1,L2)을 통하여 흐르는 전류에 의하여 발열되면 축열부(7,7')에 흡수되어 바이메탈편(6,6')의 축열부(7,7')는 퍼져서 하측부(6B,6B')가 동시에 휘어지므로 바이메탈편(6,6')의 하측부(6B,6B')가 접지단자(4)에 빠르게 접속되는 것이고, 동시에 이상전압이 인가되면 아레스터(1)자체내의 방전에 의하여 아레스터(1)의 내부 양측극이 단락되어 접지되는 것이다.The heat storage unit 7, 7 ′ is positioned at the center of the bimetal piece 6, 6 ′, and the heat storage unit 3 generates heat when the heater wires 3, 3 ′ are generated by current flowing through the trunk lines L 1 and L 2 . 7,7 ') and the heat accumulating portions 7,7' of the bimetallic pieces 6,6 'spread and the lower portions 6B, 6B' are bent at the same time so that the lower portion of the bimetallic pieces 6,6 'is bent. 6B and 6B 'are quickly connected to the ground terminal 4, and at the same time, when an abnormal voltage is applied, both internal poles of the arrester 1 are short-circuited and grounded by discharge in the arrester 1 itself.
또한, 히터선이 코일형으로 감겨있고, 바이메탈편(6,6')의 축열부(7,7')가 원통형으로 되어 있어 일단 히터선(3,3')에서 발열된 열은 외부로의 발산이 늦게 되어 충분한 시간동안 바이메탈편(6,6')의 하측부(6B,6B')가 접지단자(4)에 접속된 상태로 유지되어 이상전류를 충분히 접지시킬 수 있다.In addition, the heater wire is wound in a coil shape, and the heat storage parts 7 and 7 'of the bimetal piece 6 and 6' have a cylindrical shape, and heat generated by the heater wires 3 and 3 'once is transferred to the outside. The divergence is late so that the lower portions 6B, 6B 'of the bimetallic pieces 6, 6' are kept connected to the ground terminal 4 for a sufficient time, so that the abnormal current can be sufficiently grounded.
이상에서 설명한 바와 같이 본 고안장치에 의하면 바이메탈의 구조를 개량하여 이상전류가 흐르는 즉시 바이메탈의 정확한 동작에 의하여 전화국선 보안에 안전을 기할 수 있게 된 것이다.As described above, according to the device of the present invention, the structure of the bimetal is improved to secure the telephone line by the correct operation of the bimetal immediately after an abnormal current flows.
