The purpose of the prevent invention is to provide a cable connector for a junction box, wherein the junction box cable connector is coupled to a through-hole of a junction box by a coupler and a fastener; a predetermined distance of spacing is formed between the distribution terminal and the junction box cable connector such that the wires and optical cables connected to the junction box cable connector can be twisted; and the junction box cable connector comprises a housing containing a connector having an MTP terminal for connecting wires and optical cables and a wire connection terminal, and a coupler coupled to be able to rotate such that the housing can be penetrated and can be exposed to the outside of the junction box. The present invention is advantageous and very useful in that, in connection with connecting wires and optical communication cables to a junction box for wireless communication by a connector, coupling of a multi push-pull on-off connector (MTP) terminal is made easy, and the junction box cable connector that has been fixed to and installed on the junction box is enabled to rotate, instead of the main cable connector that is thick and long and thus is conventionally difficult for the operator to twist, such that, through such a conceptual shift, the junction box cable connector and the main cable connector can be connected (coupled) very easily.

정션박스용 케이블 커넥터Junction box cable connector
본 발명은 정션박스용 케이블 커넥터에 관한 것으로, 보다 상세하게는 전선과 광통신케이블을 정션박스를 이용해 분배함에 있어 케이블을 분리하여 콘센트 타입의 커넥터와 플러그 타입의 커넥터로 접속할 수 있도록 정션박스에 설치되는 케이블 커넥터가 회전가능토록 구성함으로써 MTP(multi push-pull on-off connector)단자가 포함된 메인케이블의 커넥터 결합에 편리한 정션박스용 케이블 커넥터에 관한 것이다.The present invention relates to a cable connector for a junction box, and more particularly, in distributing a wire and an optical communication cable using the junction box, the cable is separated and installed in the junction box to be connected to the outlet type connector and the plug type connector. The present invention relates to a cable connector for a junction box that is convenient for connector coupling of a main cable including a multi push-pull on-off connector (MTP) terminal by configuring the cable connector to be rotatable.
일반적으로, 정션박스는 외부 케이블을 인입시켜 다수개의 단자로 분리하여 이를 전기적, 통신적으로 분배하기 위한 수단으로 수분 및 이물질의 유입을 방지하기 위해 밀폐가 매우 중요하다. 종래에는 다수 가닥의 전선과 광(통신)케이블로 이루어지는 메인케이블이 직접 다수개의 정션박스 단자에 연결하여 메인케이블과 정션박스를 한꺼번에 들고 다니면서 설치하여야 하는데, 상기 메인케이블도 상당한 무게를 갖는데 정션박스도 금속재질이고 상당한 무게를 갖는 것이어서 이를 공장에서 제작하여 설치해야할 현장까지 운반하여 또 해당 위치에 이를 설치하기란 결코 쉬운 일이 아니다.In general, the junction box is a means for distributing an external cable into a plurality of terminals and distributing it electrically and communicatively, so that the junction box is very important to prevent inflow of moisture and foreign matter. Conventionally, a main cable consisting of a plurality of wires and an optical (communication) cable is directly connected to a plurality of junction box terminals and installed while carrying the main cable and the junction box at the same time. The main cable also has a considerable weight. It's made of metal and has a significant weight, so it's never easy to transport it to a site that needs to be manufactured and installed at the factory and install it in that location.
따라서 본 발명자는 별도의 전선과 광케이블을 정션박스 내부 단자에 각각 연결하고 상기 전선과 광케이블의 끝단에는 접속단자를 연결하고 이를 모아 정션박스 케이블 커넥터를 형성하였으며, 또한 메인케이블의 끝단에도 각각의 접속단자를 연결하고 이를 모아 메인 케이블 커넥터를 형성함으로써 이들을 억지끼움시켜 접속하기만 하면 모든 전선과 광케이블이 연결되므로 하였다.Therefore, the present inventors connect separate wires and optical cables to the terminals inside the junction box, respectively, and connect the connection terminals to the ends of the wires and the optical cables to form junction box cable connectors, and also connect the respective connection terminals to the ends of the main cable. Connect and collect them to form a main cable connector, so that all wires and optical cables are connected simply by forcibly connecting them.
그런데 상기 정션박스 케이블 커넥터와 메인케이블 커넥터의 중간부에는 여러 다발의 광섬유케이블을 연결하기 위한 암수의 MTP단자(MPO단자라고도 한다)가 각각 구비되어 있어 이들을 정확하게 접속해야만 한다.However, the middle part of the junction box cable connector and the main cable connector is provided with male and female MTP terminals (also called MPO terminals) for connecting a plurality of optical fiber cables, so that they must be connected correctly.
문제는 상기 MTP단자는 사각형상이어서 정확한 위치가 아니면 암단자에 숫단자를 삽입시켜 연결하기란 결코 쉽지 않다는 단점을 갖는다.The problem is that the MTP terminal is rectangular, so it is not easy to connect the male terminal to the female terminal unless it is the correct position.
그런데 더 심각한 문제는 정션박스 메인커넥터는 정션박스에 고정된 상태이고, 메인케이블은 길이만 약 50m이상이고 매우 굵어 이를 작업자가 비틀어서 MTP단자가 결합될 수 있도록 정렬시키기란 결코 쉬운 일이 아니다.However, the more serious problem is that the junction box main connector is fixed to the junction box, and the main cable is only about 50 m long and is very thick, so it is not easy to align the operator so that the MTP terminal can be twisted and combined.
따라서 결국 정션박스의 케이블 커넥터에 메인케이블 커넥터를 연결하기 위해서는 메인케이블 커넥터의 끝단을 비틀어서 정션박스의 케이블 커넥터의 MTP단자가 서로 일치되도록 정렬시켜야 하는데 이는 작업자들에 많은 힘과 고도의 집중력을 필요로 하는 것이다.Therefore, in order to connect the main cable connector to the junction box cable connector, it is necessary to twist the end of the main cable connector to align the MTP terminals of the junction box cable connector with each other, which requires a lot of power and high concentration on the workers. It is to be.

우선, 도면들 중, 동일한 구성요소 또는 부품들은 가능한 동일한 참조부호로 나타내고 있음에 유의하여야 한다. 또한, 본 발명을 설명함에 있어, 관련된 공지기능 혹은 구성에 대한 구체적인 설명은 본 발명의 요지를 모호하지 않게 하기 위하여 생략하기로 한다.First, in the drawings, the same components or parts are to be noted that the same reference numerals as possible. In addition, in describing the present invention, a detailed description of related known functions or configurations will be omitted in order not to obscure the subject matter of the present invention.
본 발명 정션박스 케이블 커넥터는 다수 가닥의 전선(122) 및 광케이블(121a)이 연결된 상태로, 상기 전선(122) 및 광케이블(121a)은 정션박스(110)의 내부 일측면에 형성된 다수개의 분배단자(112)에 분배되어 연결된다.The junction box cable connector of the present invention has a plurality of wires 122 and the optical cable 121a is connected, the wire 122 and the optical cable 121a is a plurality of distribution terminals formed on one inner surface of the junction box 110 And distributed to 112.
이때 상기 정션박스 케이블 커넥터는 정션박스(110)의 통공(111)에 결합구(150)와 체결구(160)에 의해 결합되되 상기 정션박스 케이블 커넥터에 연결된 전선(122) 및 광케이블(121a)이 트위스트(twist)될 수 있도록 회전가능하게 결합된다.At this time, the junction box cable connector is coupled to the through-hole 111 of the junction box 110 by the coupling hole 150 and the fastener 160, the wire 122 and the optical cable 121a connected to the junction box cable connector is It is rotatably coupled so that it can be twisted.
이때 전선(122) 및 광케이블(121a)이 트위스트 가능토록 상기 분배단자(112)와 정션박스 케이블 커넥터 사이는 소정의 이격거리를 가져야 한다.At this time, the wire 122 and the optical cable 121a must have a predetermined distance between the distribution terminal 112 and the junction box cable connector so that the twist.
즉 전선(122) 및 광케이블(121a)이 분배단자(112)에 연결된 상태에서도 본 발명 정션박스 케이블 커넥터가 회전가능해야만 메인케이블 커넥터(A)와 연결이 쉬울 수 있기 때문이다.That is because the junction box cable connector of the present invention can be easily connected to the main cable connector A even when the wire 122 and the optical cable 121a are connected to the distribution terminal 112.
본 발명 정션박스 케이블 커넥터는 전선(122) 및 광케이블(121a)의 접속을 위한 MTP단자(121a) 및 전선연결단자(122a)를 구비하는 접속구(130)가 내장된 하우징(140)과 상기 하우징(140)이 관통되어 정션박스(110) 외부로 노출될 수 있도록 하면서 회전은 가능토록 결합하는 결합구(150)로 이루어진다. 상기 MTP단자(121a)에는 여러 가닥의 광케이블(121a)이 연결되고, 전선연결단자(122a)에는 전선(122)이 연결된다.The junction box cable connector of the present invention includes a housing 140 and a housing 140 in which a connection port 130 including an MTP terminal 121a and a wire connection terminal 122a for connecting the electric wire 122 and the optical cable 121a is embedded. The rotation is made of a coupler 150 for coupling so that the 140 can penetrate and be exposed to the outside of the junction box 110. The optical cable 121a of several strands is connected to the MTP terminal 121a, and the wire 122 is connected to the wire connection terminal 122a.
이때 상기 하우징(140)의 상단에는 결합구(150)의 상단에 걸려 이탈을 방지하기 위한 걸림턱(142)이 형성되는데, 상기 걸림턱(142)의 하단에는 적어도 하나 이상의 돌기(142a)가 돌출 형성되도록 구성할 수도 있다.In this case, a locking jaw 142 is formed at an upper end of the housing 140 to prevent separation from the upper end of the coupling hole 150. At least one protrusion 142a protrudes from the lower end of the locking jaw 142. It may be configured to be formed.
상기 돌기(142a)는 결합구(150)의 상단에 형성된 오목홈(152)에 끼워지는데, 상기 돌기(142a)의 기능은 하우징(140)이 결합구(150)에 결합된 상태에서 회전함에 있어 일정 범위 이상은 회전하지 못하도록 제한하기 위한 것이다. 이는 전선(122) 및 광케이블(121a)의 많은 꼬임으로 인한 손상 방지를 위한 구성이다.The protrusion 142a is fitted into the concave groove 152 formed at the upper end of the coupling hole 150. The function of the protrusion 142a is to rotate in a state in which the housing 140 is coupled to the coupling hole 150. More than a certain range is to limit the rotation. This is a configuration for preventing damage due to many twists of the wire 122 and the optical cable 121a.
따라서 상기 오목홈(152)에는 적어도 하나 이상의 차단턱(153)이 형성되는데, 상기 차단턱(153)의 배치 및 갯수에 따라 돌기(142a)의 진행이 차단되어지고 결국 하우징(140)이 소정의 각도범위 내에서만 회전가능하게 된다.Accordingly, at least one blocking jaw 153 is formed in the concave groove 152, and the progress of the protrusion 142a is blocked according to the arrangement and number of the blocking jaws 153. It is possible to rotate only within the angular range.
상기 하우징(140)의 몸체 외측에는 공구결합홈(143) 또는 회전방지레버(미도시)가 돌출형성될 수도 있는데, 상기 하우징(140)을 작업자가 회전시킴에 있어 원통형상이어서 미끌리기 쉽기 때문이다. 즉 공구결합홈(143)에 스패너와 같은 공구를 끼워 회전시킬 수도 있고, 공구가 없는 경우를 대비해 하우징(140)을 직접 회전시킬 수 있는 회전방지레버를 하우징(140)의 몸체(141)와 일체로 형성시켜 측방향으로 돌출되도록 구성할 수도 있다.A tool engagement groove 143 or an anti-rotation lever (not shown) may protrude from the outer side of the body of the housing 140 because the operator has a cylindrical shape to easily rotate the housing 140 to slide the housing 140. . That is, a tool such as a spanner may be rotated by inserting a tool such as a spanner in the tool coupling groove 143, and an anti-rotation lever that directly rotates the housing 140 in case of no tool is integrated with the body 141 of the housing 140. It may be formed so as to protrude laterally.
또한 본 발명은 상기 하우징(140)의 회전을 보다 수월하게 하기 위해 몸체(141) 외측과 하우징 관통공(151) 내측면 사이에 베어링(180)을 형성할 수도 있다. In addition, the present invention may form a bearing 180 between the outer side of the body 141 and the inner surface of the housing through-hole 151 in order to facilitate the rotation of the housing 140.
이처럼 본 발명은 상기 하우징(140)이 정션박스(110)의 결합구(150)에 의해 결합된 상태지만 회전가능하게 함으로써 메인케이블 커넥터(A)와의 연결을 손쉽게 할 수 있으며, 이처럼 본 발명 정션박스케이블 커넥터가 회전가능하더라도 정션박스(110) 내부로 수분이 침투할 수 있는 구조여서는 곤란하다.As such, the present invention allows the housing 140 to be easily connected to the main cable connector A by being rotatable but coupled to the coupling hole 150 of the junction box 110, and thus, the junction box of the present invention. Even if the cable connector is rotatable, it is difficult to have a structure that allows moisture to penetrate into the junction box 110.
따라서 본 발명은 정션박스(110)의 하단과 결합구(150)의 상단 사이와, 하우징(140)의 몸체(141) 외측과 결합구(150)의 하우징 관통공(151) 내측면에는 O오링(170,171)이 형성되어 정션박스(110) 내부로 수분이 유입되는 것을 차단할 수 있도록 한다.Therefore, the present invention O-ring between the lower end of the junction box 110 and the upper end of the coupling hole 150, the outer surface of the body 141 of the housing 140 and the inner surface of the housing through-hole 151 of the coupling hole 150 (170,171) is formed to block the inflow of moisture into the junction box (110).
상술 한 바와 같이 본 발명은 비록 한정된 실시예들에 의해 설명되었으나, 본 발명은 이것에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.As described above, although the present invention has been described by way of limited embodiments, the present invention is not limited thereto, and the technical concept of the present invention and the following will be described by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the appended claims.
