  However, in the conventional wiring duct, when it is desired to arbitrarily install a plurality of wiring ducts on an installation surface such as a ceiling surface or a wall surface, the end of the plurality of wiring ducts is attached before the wiring duct is attached to the installation surface. The connecting joint must be mechanically and electrically connected from the side opening side to form an integral wiring duct unit. That is, a plurality of wiring ducts can be connected by inserting and engaging an end opening in the longitudinal direction of the other wiring duct with a connecting joint connected to one wiring duct. . Therefore, since it is necessary to prepare a desired wiring duct unit to be arranged on the installation surface in advance, if the desired wiring duct unit is relatively long, the installation work requires a large number of people, and construction is difficult. It was complicated.

  In addition, as another method of arbitrarily installing multiple wiring ducts on the installation surface, after connecting one wiring duct to the installation surface, connect the connecting joint, and then connect the other wiring duct to the joiner. It is also possible to do. However, even in such a method, the connection of the connecting joint and the connection of the wiring duct to the joint is a method of inserting from the end opening side in the longitudinal direction of the wiring duct. The work must be performed while supporting, and particularly when the installation surface is a ceiling surface, the installation work becomes very complicated.

  The present invention has been made in view of the above problems, and can be connected from the opening side of the wiring duct and can easily perform mechanical connection and electrical connection to improve the efficiency of installation work.

In short, the process of projecting is not a problem, and as a result, in a direction orthogonal to the longitudinal direction. It only needs to protrude. For the operation of the operation member, for example, the operation member automatically operates in conjunction with the operation by the installation operator operating the operation member or the operation of connecting the wiring duct coupling portion to the wiring duct.

  As shown in FIG. 1, the wiring device 1 is a so-called I-shaped joiner, is made of a synthetic resin and is formed in a substantially rectangular shape, and includes a main wall surface 2 and a wiring duct coupling portion 3. On the back side of the wiring duct coupling portion 3, a main wall surface 2 is formed along the longitudinal direction of the wiring duct coupling portion 3. Further, mechanical connection means 4 and electrical connection means 5 are provided at both ends of the wiring duct coupling portion 3. Furthermore, the wiring duct coupling portion 3 is provided with an operating member 6 for connecting and operating the mechanical connecting means 4 and the electrical connecting means 5. The actuating member 6 has a substantially cylindrical shape, is formed in a truncated cone shape having a tapered portion 6a with a tapered front end portion, and is configured as an operation portion 6b with a flat rear end portion. 3 is guided by a circular through hole 2a formed in the inner wall and the main wall surface 2 so as to be slidable. The operating member 6 is in a state of protruding from the surface of the main wall surface 2 through the through hole 2a when not operating. The actuating member 6 is held by the stopper projection 6c provided on the tapered surface 6a without coming out of the through hole 2a.

  The mechanical connection means 4 is located below the operating member 6 in the drawing, and a pair of engagement elements 4a that can project and retract in a direction perpendicular to the longitudinal direction through slots 3a formed on both sides of the wiring duct coupling portion 3. have. As shown in FIG. 2, each engaging element 4 a is given an elastic force by a spring member 4 b in a direction in which the back surfaces abut each other, that is, a direction in which the engaging element 4 a is stored in the wiring duct coupling portion 3. Is given an elastic force. Therefore, each engagement element 4a forms an abutting portion 4c with which the back surfaces abut each other, and can project and retract in the direction of the arrow shown in the figure.

  The electrical connection means 5 is located below the mechanical connection means 4 and is formed of a metal material having conductivity and elasticity, and is orthogonal to the longitudinal direction through the slot 3b formed on both sides of the wiring duct coupling portion 3. Can be sunk in the direction.

  The main wall surface 2 is configured so that the length in the direction perpendicular to the center line, that is, the length in the width direction, is different from the left and right with respect to the center line in the longitudinal direction defined by the positional relationship of the wiring duct coupling portion 3 ing. That is, the dimensional relationship of W1> W2 is established, and the left and right wall surfaces of the main wall surface 2 have an asymmetric shape.

  As shown in FIG. 3, the wiring duct 10 can be mounted at an arbitrary position so that an electric device such as a lighting fixture or an outlet can be disposed at an arbitrary position. Power can be supplied at any mounting position. The wiring duct 10 has a long duct body 11 having a U-shaped cross section. For example, the entire outer surface of a metal duct base material such as a galvanized steel sheet is covered with a synthetic resin insulator so as to be integrated. Is formed. An opening 12 is formed in the duct body 11 along the longitudinal direction, and a pair of support collars 13 are formed on both sides of the opening 12. Further, an attachment hole (not shown) for attaching the installation surface to the installation surface with a screw or the like is formed on the wall surface opposite to the opening 12.

  A pair of insulative conductor holding portions 14 are provided along the longitudinal direction at both side positions inside the duct body 11, and a conductive portion 15 as a pair as a power source line is provided in the conductor holding portions 14. Installed along the direction. One of the conductive portions 15 is a voltage side conductive portion 15a, and the other is a ground side conductive portion 15b. In addition, on one outer surface of the support flange 13 of the opening 12, that is, the outer surface of the support flange 13 on the ground-side conductive portion 15b side, a protrusion 16 for polarity display is integrally formed. Note that a conductive portion 15 c serving as a ground line is provided on the inner wall surface on the side opposite to the opening 12.

  Next, the connection between the wiring device 1 and the wiring duct 10 will be described with reference to FIG. As shown in FIG. 4A, the wiring duct coupling portion 3 of the wiring device 1 is inserted from the opening 12 of the wiring duct 10. Then, the back surface of the main wall surface 2 of the wiring device 1 is in a state where it overlaps the outer surface of the support flange 13 of the wiring duct 10. Next, the operation portion 6 b of the operating member 6 protruding from the surface of the main wall surface 2 is pressed. The operating member 6 slides while being guided by the inner wall of the wiring duct coupling portion 3 and the through hole 2 a of the main wall surface 2, and enters the wiring duct coupling portion 3. At this time, the distal end portion of the actuating member 6 collides with the contact portion 4c formed by the engagement element 4a, and further acts so as to spread the contact portion 4c by the tapered surface 6a. Subsequently, as the immersion proceeds, as shown in FIG. 4B, the back surface of the engaging element 4a is pressed by the cylindrical portion of the actuating member 6, and the engaging element 4a protrudes through the slot 3a, and the support rods on both sides are supported. Engage with the inside of the part 13 to complete the mechanical connection.

  On the other hand, the electrical connection is also performed on the extension line of the mechanical connection. In other words, since the electrical connecting means 5 is located below the mechanical connecting means 4, when the immersion is advanced by the sliding movement of the operating member 6, the operating member 6 passes through the mechanical connecting means 4. Similarly, the electrical connecting means 5 acts so as to protrude from the wiring duct coupling portion 3. Therefore, the electrical connection means 5 is pressed outward by the cylindrical portion of the actuating member 6 and protrudes through the slot 3b. The electrical connection means 5 contacts the conductive portions 15 on both sides, and the electrical connection is made. Complete.

The mechanical connection and the electrical connection as described above are performed by operating the operation member 6 in the direction in which the wiring duct coupling portion 3 is connected to the wiring duct 10 so that both the mechanical connecting means 4 and the electrical connecting means 5 are connected. It can protrude in the direction orthogonal to the longitudinal direction. That is, the operation direction of the actuating member 6 is converted into a movement that protrudes in a direction perpendicular to the longitudinal direction with respect to the mechanical connection means 4 and the electrical connection means 5.
For such operations, the mechanical connection means 4 and the electrical connection means 5 are arranged so as to be juxtaposed in the connection direction, and the actuating member 6 is provided with the mechanical connection means 4 and the electrical connection means 5. These are common members that project in a direction perpendicular to the longitudinal direction.
In a state where the mechanical connection and the electrical connection are completed, the operation portion 6b of the actuating member 6 is substantially flush with the main wall surface 2 and has a preferable form in appearance, as well as the mechanical connection and the electrical connection. It is easy to visually confirm that the connection is complete. Further, since the left and right wall surfaces of the main wall surface 2 are asymmetrical, the main wall surface 2 does not overlap the polar display protrusions 16, and the polarity display protrusions 16 appear on the outer surface, The main wall surface 2 and the polarity display protrusion 16 are substantially flush with each other to form the outer surface. Therefore, it can be easily visually determined that the connection is properly made without any error in the direction, and the height of the main wall surface 2 and the polarity display protrusion 16 is substantially flush with each other. It becomes a compact configuration without causing an increase in. In order to remove the wiring device 1 from the wiring duct 10, a release mechanism for mechanical connection means 4 and electrical connection means 5 (not shown) is provided.

In this assembly, the wiring device 1 is connected from the opening 12 side of the wiring duct 10 (FIG. 7B), and the cover 21 is put on the wiring device 1 (FIG. 7C). In this case, the cover 21 is substantially flush with the main wall surface 2 and the ridge 16 for polarity display, so that the cover 21 is U-shaped as described above without being affected by the ridge 16 for polarity display. Since the mounting direction is not restricted, the mounting work can be easily performed. Note that the cover 21 may be provided integrally with the main wall surface 2.
