Description

전선공동구의 연결부재{The joint member of underground multi-purpose duct for electric wire}Joint member of underground multi-purpose duct for electric wire}

본 발명은, 전선을 땅 속에 매설하는 전선공동구를 서로 연결하기 위한 전선공동구의 연결부재에 관한 것이다.The present invention relates to a connecting member of a wire tool for connecting the wire tool to embed the wire in the ground.

전선공동구를 서로 연결하기 위해서는, 도 7 에 나타낸 바와 같이 조인터 (1) 를 전선공동구 (2) 단부의 오목부 (3) 에 삽입하고, 전선공동구 (2) 의 연결 구멍 (4) 에서 조인터 (1) 의 세로 구멍 (5) 을 통해 반대측에 달할 때까지 금속제 연결부재 (6) 를 타입하는 방법을 사용하고 있다.In order to connect the electric wire joints with each other, as shown in Fig. 7, the joint 1 is inserted into the recess 3 at the end of the electric wire joint 2, and the joint is connected at the connection hole 4 of the electric wire joint 2; The method of typing the metal connecting member 6 is used until it reaches the opposite side through the vertical hole 5 of (1).

이 방법에서는, 전선공동구 (2) 의 상면에서 연결부재 (6) 를 타입하여야 한다. 따라서, 도 8 에 나타낸 바와 같이 전선공동구 (2) 를 단으로 쌓아 부설하여 단면을 정렬시킨 경우에는, 중간단이나 하부단의 전선공동구 (2) 에 대해서는 그 상면에서 연결부재 (6) 를 타입할 수 없어 연결할 수 없다는 문제가 있었다.In this method, the connecting member 6 is to be typed on the upper surface of the wire cavity 2. Therefore, as shown in FIG. 8, in the case where the wire ducts 2 are stacked and laid in stages to align the cross sections, the connecting member 6 may be formed on the upper surface of the wire ducts 2 at the intermediate or lower ends. There was a problem that I could not connect.

그래서 본 발명자들은, 도 9 에 나타낸 바와 같이 스프링 (7) 을 내장한 신축가능한 중공 연결부재 (8) 를 조인터 (1) 의 세로 구멍 (5) 에 삽입하고, 조인터(1) 가 전선공동구 (2) 의 오목부 (3) 에 소정 위치까지 삽입되었을 때 연결부재 (8) 가 상하로 신장하여 전선공동구 (2) 의 연결 구멍 (4) 과 결합하도록 한 연결법을 먼저 개발하였다. 그러나, 전선공동구 (2) 의 관로 사이즈가 작아지면 연결부재 (8) 도 상사적으로 짧아져 충분한 신축 스트로크를 확보할 수 없으므로, 확실한 연결이 불가능해진다는 문제가 남아 있었다. 또, 이러한 연결부재 (8) 는 상하 양단을 손으로 눌러 축소시켜 조인터 (1) 의 세로 구멍 (5) 에 삽입해야만 하므로, 취급이 용이하지 않다는 문제도 있었다.Thus, the present inventors insert the flexible hollow connecting member 8 having the spring 7 therein into the longitudinal hole 5 of the jointer 1, and the jointer 1 is a wire cavity. A connection method was first developed in which the connecting member 8 extends up and down to be engaged with the connecting hole 4 of the electric wire cavity 2 when it is inserted into the recessed part 3 of (2) to a predetermined position. However, when the pipe size of the electric wire cavity 2 decreases, the connecting member 8 also becomes shorter similarly, so that sufficient stretching stroke cannot be secured, so that a reliable connection remains. In addition, since the connecting member 8 must be pressed down by both upper and lower ends by hand to be inserted into the vertical hole 5 of the jointer 1, there is also a problem that handling is not easy.

본 발명은 상기한 종래의 문제점을 해결하여, 전선공동구의 관로 사이즈가 작고 상면에서 연결부재를 타입할 수 없는 경우에도 전선공동구를 확실하게 연결할 수 있으며, 또한 취급이 용이한 전선공동구의 연결부재를 제공하기 위해 이루어진 것이다.The present invention solves the above-mentioned problems, and even when the pipe size of the wire duct is small and the connection member cannot be typed on the upper surface, the wire duct can be reliably connected, and the connection member of the wire duct is easy to handle. It was made to provide.

It is characterized in that the movable coupling plate which is widened up and down when inserted to engage with the inner surface of the concave portion of the electric wire cavity. Moreover, it is preferable to form the projection for pushing inside the main-body part.

본 발명의 전선공동구의 연결부재는, 본체부 상하에 가동결합판을 형성한 것으로, 이들 가동결합판이 전선공동구의 오목부에 소정 위치까지 삽입되었을 때 조인터의 세로 구멍에서 상하로 벌어지는 것을 이용하여 전선공동구를 연결하도록 한 것이다. 따라서, 종래의 연결부재와 같이 큰 스트로크는 불필요하고, 또 전체가 U 자형이기 때문에 종래의 봉형 연결부재에 비해 취급이 용이하다는 이점이 있다.The connecting member of the wire joint according to the present invention is provided with a movable coupling plate above and below the main body, and when the movable coupling plate is inserted into the recess of the wire cavity to a predetermined position, It is to connect the wire harness. Therefore, as with the conventional connecting member, a large stroke is unnecessary, and since the whole is U-shaped, there is an advantage that it is easier to handle than a conventional rod-shaped connecting member.

이하에, 본 발명의 바람직한 실시형태를 설명한다.EMBODIMENT OF THE INVENTION Below, preferable embodiment of this invention is described.

도 1 은 제 1 실시형태를 나타낸 사시도이다. 본 발명의 전선공동구의 연결부재는 전체가 스테인리스 등의 탄성이 있는 금속판으로 이루어진 것으로, 도면 부호 (10) 는 본체부, 부호 (11) 은 그 상하를 굴곡시켜서 일체로 형성된 가동결합판이다. 도 2 에 나타낸 바와 같이, 이 본체부 (10) 는 전선공동구 (2, 2) 를 연결하는 조인터 (1) 의 세로 구멍 (5) 에 삽입할 수 있는 길이로 되어 있다. 또 가동결합판 (11) 은, 외력이 가해지지 않은 상태에서는 45 도 정도의 각도로 상하로 벌어지도록 되어 있다. 이 제 1 실시형태에서는, 가동결합판 (11) 의 이면에 짧은 밀어넣기용 돌기 (12) 가 절단된 후 세워지도록 형성되어 있다.1 is a perspective view showing a first embodiment. The connecting member of the electric wire joint of the present invention is made of a metal plate with elasticity such as stainless steel as a whole, and reference numeral 10 denotes a main body portion, and reference numeral 11 denotes a movable coupling plate integrally formed by bending the upper and lower portions thereof. As shown in Fig. 2, the main body portion 10 has a length that can be inserted into the longitudinal hole 5 of the jointer 1 connecting the electric wire cavity holes 2 and 2. In addition, the movable coupling plate 11 is opened up and down at an angle of about 45 degrees without an external force being applied. In this 1st embodiment, it is formed so that a short pushing protrusion 12 may be cut and stood on the back surface of the movable coupling plate 11.

이 연결부재는, 도 2 에 나타낸 바와 같이 조인터 (1) 의 세로 구멍 (5) 에 삽입한 다음 그대로 조인터 (1) 를 전선공동구 (2) 단부의 오목부 (3) 에 삽입한다. 이 때, 가동결합판 (11) 은 도 2 의 중간단에 나타낸 바와 같이 전선공동구 (2) 의 단면에 눌려 내측으로 휘고, 소정 위치까지 조인터 (1) 가 삽입되면 그 자체의 스프링력에 의해 상하로 벌어져 전선공동구 (2) 의 오목부 내부에 형성된 결합용 사면 (13) 과 결합한다. 따라서, 조인터 (1) 는 전선공동구 (2) 와 강고하게 연결되고, 조인터 (1) 의 반대측도 동일한 구조로 해두면 2 개의 전선공동구 (2) 가 서로 연결된다.This connecting member is inserted into the longitudinal hole 5 of the jointer 1, as shown in FIG. 2, and then inserts the jointer 1 into the recessed part 3 of the end part of the electric wire cavity 2 as it is. At this time, the movable coupling plate 11 is pressed by the end face of the electric wire cavity 2 as shown in the middle end of FIG. 2 and bent inward. When the jointer 1 is inserted to a predetermined position, the movable coupling plate 11 is driven by its own spring force. It opens up and down and engages with the coupling slope 13 formed in the recessed part of the electric wire cavity 2. Therefore, the jointer 1 is firmly connected to the electric wire cavity 2, and if the opposite side of the jointer 1 is also the same structure, the two electric wire cavity 2 is connected to each other.

또, 밀어넣기용 돌기 (12) 는, 조인터 (1) 를 전선공동구 (2) 단면의 오목부 (3) 에 삽입할 때 조인터 (1) 의 세로 구멍 (5) 의 후단면과 결합하여, 연결부재가 빠지는 일없이 확실하게 밀어 넣어지기 위한 것이다. 제 1 실시형태에서는 이 밀어넣기용 돌기 (12) 는 가동결합판 (11) 의 이면에 형성되어 있지만, 도 3 에 나타낸 제 2 실시형태에서는 종단면이 실크모자형인 금속판을 본체부 (10) 에 용접하여 밀어넣기용 돌기 (12) 가 형성되고 있다. 또한, 도 4 에 나타낸 제 3 실시형태에서는 수평단면이 U 자형인 금속판을 본체부 (10) 에 용접하여 밀어넣기용 돌기 (12) 가 형성되고 있다.Moreover, the pushing projection 12 engages with the rear end surface of the longitudinal hole 5 of the joining device 1 when the joining device 1 is inserted into the recessed portion 3 of the cross section of the electric wire cavity 2. This is to ensure that the connecting member is pushed in without fail. In the first embodiment, the pushing projection 12 is formed on the rear surface of the movable coupling plate 11, but in the second embodiment shown in Fig. 3, a metal plate whose longitudinal section is silk hat-shaped is welded to the main body portion 10. And the projection 12 for pushing is formed. In addition, in the 3rd Embodiment shown in FIG. 4, the projection 12 for pushing and welding the metal plate of a U-shaped horizontal cross section to the main-body part 10 is formed.

도 5 에 나타낸 제 4 실시형태에서는, 연결부재의 가동결합판 (11) 을 본체부 (10) 와 별도로 하고, 스프링 (14) 에 의해 가동결합판 (11) 이 항상 열린 상태로 탄성적으로 지지되어 있다. 이렇게 구성되어 있기 때문에, 연결부재로서 판 두께가 두꺼운 것을 선택해도 적절하게 가동결합판 (11) 이 요동하므로, 강도적으로 우수하게 할 수 있다. 또, 도 6 에 나타낸 바와 같이 제 5 실시형태에서는, 연결부재의 가동결합판 (11) 을 별도로 하고, 본체부 (10) 의 동체를 상기 조인터 (1) 의 세로구멍 (5) 에 대응하도록 원형으로 하여 적절하게 밀어 넣어지게 되어 있다.In the fourth embodiment shown in FIG. 5, the movable coupling plate 11 of the connecting member is separated from the main body portion 10, and the movable coupling plate 11 is always elastically supported by the spring 14 in an open state. It is. Since it is comprised in this way, even if the plate | board thickness is chosen as a connection member, since the movable coupling plate 11 fluctuates suitably, it can be made excellent in strength. In addition, as shown in FIG. 6, in 5th Embodiment, the movable coupling plate 11 of a connection member is isolate | separated, and the body of the main-body part 10 corresponds to the longitudinal hole 5 of the said joiner 1, Moreover. It is circular and is pushed in appropriately.

이상에 설명한 바와 같이, 본 발명의 연결부재는 조인터의 세로 구멍에 삽입할 수 있는 길이의 본체부 상하에, 조인터가 전선공동구의 오목부에 소정 위치까지 삽입되었을 때 조인터의 세로 구멍에서 상하로 벌어져 전선공동구의 오목부 내면과 결합하는 가동결합판을 요동가능하게 형성한 것이므로, 종래의 봉형 연결부재와는 달리 큰 신축 스트로크를 확보하지 않아도 확실하게 조인터와 전선공동구를 연결할 수 있다. 따라서, 전선공동구의 관로 사이즈가 작고 상면에서 연결부재를 박아 넣을 수 없는 경우에도, 전선공동구를 확실하게 연결할 수 있다.As described above, the connecting member of the present invention is formed in the vertical hole of the joint when the joint is inserted up to a predetermined position in the concave portion of the wire duct, above and below the main body portion having a length that can be inserted into the vertical hole of the joint. Since the movable coupling plate is formed to be swingable so as to swing up and down and engage with the inner surface of the recess of the wire cavity, unlike the conventional rod-shaped connecting member, the joint and the wire cavity can be reliably connected without securing a large stretch stroke. Therefore, even when the conduit size of the electric wire tool is small and the connecting member cannot be driven from the upper surface, the electric wire tool can be reliably connected.

또, 본 발명의 연결부재는 가동결합판을 요동가능하게 형성한 것이므로, 도 2 에 나타낸 바와 같이 단순히 조인터와 함께 연결부재를 전선공동구의 오목부에 밀어넣기만 하면 된다. 따라서, 종래의 신축식 봉형 연결부재와 비교하여, 취급이 용이한 이점이 있다.In addition, since the connecting member of the present invention is a movable coupling plate formed so as to be swingable, it is only necessary to push the connecting member together with the jointer into the concave portion of the wire cavity as shown in FIG. Accordingly, there is an advantage in that it is easy to handle compared with the conventional stretchable rod connecting member.
