Description
본 발명은 통신케이블 연결용 단자함에 관한 것으로, 특히 단자핀 양단에 나사산과 길이방향으로 케이블접속홈이 형성되어, 이 접속홈에 케이블심선이 위치하여 나사결합으로 접속하는 통신케이블 연결용 단자함에 관한 것이다.The present invention relates to a terminal box for connecting a communication cable, and in particular, a cable connection groove is formed in both ends of the terminal pin in the threaded direction, the cable core wire is located in the connection groove is connected to the terminal box for connecting the communication cable screwed will be.
일반적으로 통신케이블 연결용 단자함은 외부로부터 건물, 즉 일반가정이나 사무실 등으로 인입되는 복수의 통신케이블이 입력단자에 각각 연결되고, 출력단자에 해당하는 통신기기로 연결되는 것이다.In general, a terminal box for connecting a communication cable is a plurality of communication cables that are introduced into a building, that is, a general home or an office from the outside, are connected to input terminals, respectively, and connected to communication devices corresponding to output terminals.
이와 같은 단자함은 수 내지 수백 가닥이상의 통신케이블을 건물내로 분기시키기 위하여 건물내의 통신기기와 교신을 위한 중간 매개체의 기능을 하는 것으로, 연결되는 통신케이블의 수에 따라 연결단자핀의 수도 많아지게 된다.Such a terminal box functions as an intermediate medium for communicating with a communication device in a building in order to branch a communication cable of several to several hundred strands into a building, and the number of connection terminal pins increases according to the number of communication cables to be connected.
이러한 종래의 통신케이블 연결용 단자함은, 도 1 내지 도 3에 나타낸 바와 같이, 절연재질로 되어 있으면서 커버(1)를 구비한 단자판(2)과, 이 단자판(2)에 설치되는 다수 개의 단자핀(3)으로 이루어진다.As shown in FIGS. 1 to 3, a terminal box for connecting a conventional communication cable is made of an insulating material and includes a terminal plate 2 having a cover 1, and a plurality of terminal pins provided on the terminal plate 2. It consists of (3).
여기서, 단자판(2) 양쪽으로 노출된 단자핀(3) 일단은 국선단자부(3a)로서 외부로부터 인입되는 인입케이블(4a)이 여러 회수로 권취되고, 타단은 내선단자부(3b)로서 출력케이블(4b)이 여러 회수로 권취되어 인입케이블(4a)과 출력케이블(4b)이 접속되므로써 해당 통신기기와 통신을 할 수 있게 된다.Here, one end of the terminal pin 3 exposed on both sides of the terminal plate 2 is wound with a plurality of times the inlet cable 4a drawn from the outside as the trunk line terminal portion 3a, and the other end is an output cable (3) as the inner terminal portion 3b. 4b) is wound several times, and the inlet cable 4a and the output cable 4b are connected, thereby enabling communication with the corresponding communication device.
그런데, 단자핀(3)에 통신케이블(4a,4b)을 접속할 때 권취된 케이블(4a,4b)이 단자핀(3)으로부터 벗겨지거나 빠져나가는 것을 방지하기 위하여 단자핀(3)을 사각단면형상으로 하여 케이블(4a,4b)을 권취하는 방법을 이용하고 있으나, 단자핀(3)과 권취된 케이블(4a,4b)의 접촉면적이 작아 접속상태가 불량하게 되고 이에 따라 통신품질을 크게 저하시킬 염려가 있다.By the way, when connecting the communication cables 4a and 4b to the terminal pins 3, the terminal pins 3 have a rectangular cross-sectional shape in order to prevent the cables 4a and 4b wound up from being peeled off or coming out of the terminal pins 3. Although the method of winding the cables 4a and 4b is used, the contact area between the terminal pin 3 and the wound cables 4a and 4b is small and the connection state is poor, thereby greatly reducing the communication quality. There is concern.
그래서, 권취회수를 증가시켜 접촉면적을 증가시키고 있으나, 이 경우 케이블(4a,4b) 피복의 탈피량이 그 만큼 증가하게 되고, 이에 따라 탈피작업시간이 증가되며 권취작업시 단선도 많이 발생할 수 있다는 결점이 있다.Therefore, although the contact area is increased by increasing the number of windings, in this case, the stripping amount of the cable 4a, 4b sheathing increases accordingly, which increases the stripping time and may cause a lot of disconnection during the winding operation. There is this.
또한, 접속작업시 케이블(4a,4b) 피복을 일일이 벗겨 심선을 노출시킨 다음 단자핀(3)에 권취하여야 하므로 접속작업능률이 떨어지고, 또한 피복이 완전히 벗겨지지 않아 접속상태가 불량하게 되며, 단선 등 권취작업이 잘못되었을 경우 권취된 케이블을 풀어서 다시 권취하는 작업이 번거롭다는 결점이 있다.In addition, the cable 4a and 4b should be peeled off to expose the core wires and then wound on the terminal pin 3 so that the connection work efficiency is reduced, and the sheath is not completely peeled off, resulting in poor connection. If the winding work is wrong, there is a drawback that it is cumbersome to unwind and rewind the wound cable.
그리고, 단자핀(3)은 습기나 우수 등에 의한 부식을 방지하기 위해 니켈(Ni)도금을 하여 안정적인 통신상태를 장기간 유지하도록 되어 있으나, 니켈(Ni)은 전도성이 불량하기 때문에 통신품질을 저하시키는 결점도 있다.In addition, the terminal pin 3 is nickel-plated to prevent corrosion due to moisture or rain, and thus maintains a stable communication state for a long time. However, nickel (Ni) degrades communication quality because of poor conductivity. There are also drawbacks.
본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로, 단자핀에 나사산을 형성하고 길이방향으로 케이블접속홈을 가공한 다음 접속너트를 나사결합시켜 접속능률을 향상시키고 간단하게 접속 및 해체작업을 할 수 있으며, 케이블의 탈피량을 줄임과 더불어 부식을 방지할 수 있는 통신케이블 연결용 단자함을 제공하는데 그 목적이 있다.The present invention has been made to solve the problems described above, to form a screw thread on the terminal pin and machine the cable connection groove in the longitudinal direction, and then screw the connection nut to improve the connection efficiency and simply connect and dismantle Its purpose is to provide a terminal box for connecting communication cables that can work, reduce the amount of cable stripping and prevent corrosion.

It is preferable to form and to make the outer periphery non-circular.
단자부(42,43)중에서 국선단자부(42)는 외부로부터 인입케이블(31)이 연결되고, 내선단자부(43)는 해당 통신기기(도시되지 않음)와 연결된 출력케이블(32)이 연결되어 외부와 통신기기 사이에 통신할 수 있도록 하는 것으로, 단자부(42,43)는 외주연에 나사산이 형성되어 있음과 더불어 길이방향으로 케이블접속홈(44)이 형성되어 있다.Among the terminal parts 42 and 43, the trunk line terminal part 42 is connected to the incoming cable 31 from the outside, and the internal terminal part 43 is connected to the output cable 32 connected to the corresponding communication device (not shown). In order to be able to communicate between communication devices, the terminal portions 42 and 43 are formed with a screw thread on the outer circumference and a cable connection groove 44 in the longitudinal direction.
케이블접속홈(44)은 단자부(42,43)에 길이방향으로 형성되어 통신케이블(31,32)의 심선이 압입되어 끼워지는 부분으로, 케이블접속홈(44)의 내경은 피복이 벗겨지지 않은 상태에서의 통신케이블(31,32) 직경보다는 작고 피복이 벗겨진 심선의 직경보다는 동일 혹은 약간 크게 하여 억지끼움이 이루어질 수 있게 함이 바람직하다.The cable connection groove 44 is formed in the terminal portions 42 and 43 in the longitudinal direction, and the core wires of the communication cables 31 and 32 are press-fitted into the cable connection groove 44. The inner diameter of the cable connection groove 44 is not peeled off. It is preferable that the interference fit can be made to be smaller than the diameter of the communication cable (31,32) in the state and the same or slightly larger than the diameter of the stripped core wire.
접속너트(50)는 단자부(42,43)와 나사결합되어 통신케이블(31,32)의 피복을 나사산에 따라 절개되고 동시에 케이블접속홈(44)에 통신케이블(31,32)의 심선이 압입되는 것으로, 접속너트(50)의 나사산은 단자부(42,43)의 나사산에 대응되게 형성되어 있다.The connection nut 50 is screwed with the terminal portions 42 and 43 to cut the sheath of the communication cables 31 and 32 according to the thread, and at the same time, the core wires of the communication cables 31 and 32 are press-fitted into the cable connection groove 44. The threads of the connection nut 50 are formed to correspond to the threads of the terminal portions 42 and 43.
여기서, 접속너트(50)의 높이는 단자부(42,43) 길이와 동일하게 하거나 약간 작게 하여 피복이 나사선에 의해 절개된 케이블(31,32)의 심선을 완전히 덮어줄 수 있도록 함이 바람직하다.Here, it is preferable that the height of the connection nut 50 is equal to or slightly smaller than the length of the terminal portions 42 and 43 so that the sheath can completely cover the core wires of the cables 31 and 32 cut by the thread.

상기와 같이 이루어진 본 발명의 단자함에 케이블(31,32)을 연결하는 방법을 설명하면 다음과 같다.Referring to the method of connecting the cables 31 and 32 to the terminal box of the present invention made as described above are as follows.
먼저 피복이 벗겨지지 않은 통신케이블(31,32) 가닥을 단자핀(40)의 케이블접속홈(44)에 가지런하게 정렬하여 댄 상태에서 접속너트(50)를 조여 나사결합시킨다.First, the communication cables 31 and 32 which are not peeled off are aligned with the cable connection grooves 44 of the terminal pins 40 so as to be tightened, and the connection nuts 50 are tightened and screwed together.
단자핀(40)에 접속너트(50)를 나사결합시킴에 따라 통신케이블(31,32)은 그 피복이 나사선에 따라 절개되면서 심선이 노출되고, 노출된 심선은 단자핀(40)의 케이블접속홈(44)에 압입되면서 끼워져 간단하게 전기적 접속이 완료되는 것이다.As the connection nut 50 is screwed to the terminal pin 40, the communication cables 31 and 32 are cut along the threaded wire, and the core wire is exposed, and the exposed core wire is connected to the cable of the terminal pin 40. It is inserted into the groove 44 while being simply inserted to complete the electrical connection.
그리고, 접속된 통신케이블(31,32)의 분리작업은 단자핀(40)에 나사결합된 접속너트(50)를 푼 다음 케이블접속홈(44)에 끼워진 통신케이블(31,32)을 잡아당겨 분리하기만 하면 간단하게 분리할 수 있다.Then, the disconnection operation of the connected communication cable (31, 32) loosen the connection nut 50 screwed to the terminal pin 40, and then pull the communication cable (31, 32) inserted into the cable connection groove 44 You can simply remove it.
한편, 단자핀(40)은 수 ∼ 수백 개 이상이므로 접속에 소요되는 시간이 상당히 소요되는 바, 전용지그를 사용하여 접속너트(50)를 단자핀에 나사결합 혹은 해체작업을 하면 그 접속작업을 신속하게 할 수 있다.On the other hand, since the number of terminal pins 40 is hundreds to hundreds or more, the time required for the connection is considerably high. When the connection nut 50 is screwed or dismantled to the terminal pins using a dedicated jig, the connection work is quickly performed. It can be done.
본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the technical idea of the present invention.
일례로 도 8에서 보인 바와 같이, 접속너트(50)를 그 일단이 막혀진 상태 즉 캡상으로 제작하여, 단자부(42,43)에 결합되는 케이블(31,32)의 심선이 단자부(42,43)측방에서 인입되어 선단부쪽으로 접속되는 경우 심선선단이 접속너트(50)에 의해 외부로 노출되는 것을 방지하므로써 다른 통신케이블(31,32)과 접촉에 의한 혼선이나 잡음의 발생을 방지하는데 유효하다.For example, as shown in FIG. 8, the connecting nut 50 is formed in a closed state, that is, in a cap shape, and the core wires of the cables 31 and 32 coupled to the terminal parts 42 and 43 are connected to the terminal parts 42 and 43.
