Description

  The present invention relates to a conductive device such as a lighting duct device capable of supplying power to an electrical device such as a lighting fixture.

  Conventionally, by electrically connecting the ends of a conductive device, for example, a plurality of lighting ducts, using a joiner made of a wiring device, it is possible to supply power to a lighting fixture attached at an arbitrary position of the lighting duct. A lighting duct device is provided.

The electrical connection between the end of the lighting duct and the joiner in this type of lighting duct device is made by connecting the joiner from the open longitudinal end of the lighting duct to the inside of the end of the lighting duct, and along the longitudinal direction of the lighting duct. This is done by bringing the contact metal fittings of the plug-in type jointer into contact with a conductor disposed in the lighting duct. By this connection, the conductors corresponding to the longitudinal direction of the lighting ducts arranged adjacent to each other are electrically connected via a joiner (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2003-197026 (paragraphs 0001-0053, FIGS. 1 to 6)

  The lighting duct device assembled by connecting the lighting duct and the joiner by inserting the joiner into the end portion of the lighting duct along the longitudinal direction of the duct as in Patent Document 1 has room for improvement in the following points. There is.

  When the joiner is inserted into the end of the lighting duct and connected, the insertion posture is not appropriate.For example, when the lighting duct is viewed from the side, the joiner is forcibly inserted obliquely upward with respect to the lighting duct In addition, when the lighting duct is viewed from above (rear side), it may be forcibly inserted in a state where the joiner is deviated in parallel to the lighting duct or is inclined.

  In these cases, workability is poor because it is difficult to insert. Not only that, the part of the insulation supporting the conductor in the lighting duct may be stripped off and it may be sandwiched between the conductor and the joint fitting of the joint, so that the conductor and There is a possibility that the electrical connection with the contact metal fitting becomes defective. In addition, since the contactor fitting of the joiner is generally made of a conductive leaf spring, if excessive deformation occurs due to an unreasonable insertion operation as described above, the spring property is lowered, and thereby the conductor There is a risk that the electrical connection between the contact fitting and the contact metal fitting will be poor.

  In addition, the lighting duct device may be laid out in a complicated shape such as a square shape or a square shape by connecting a plurality of lighting ducts with a joiner. The joiner may not be able to be inserted inside the end of the duct. Therefore, in the case of a complicated layout, the entire lighting duct device is pre-assembled on the ground side, or the lighting duct device is divided and pre-assembled before being installed on the ceiling or the like.

In the present embodiment, the predetermined shapes are linear, that is, arranged so as to be positioned on the extension line in the longitudinal direction of the conductive portion 2 as shown by a two-dot chain line in FIG. These conductive parts 2 are attached to installation places such as a ceiling or a room wall in a building. When the installation location is the ceiling, the installation to the ceiling is directly attached with screws to the ceiling surface, or embedded in the embedded frame that is embedded in the ceiling and fixed to this frame, or the ceiling surface Any one of the aspects of the pipe hanging attached to the lower end of the hanging pipe attached to the hanger via the hanger can be selected.

  As shown in FIG. 4 and the like, each conductive portion 2 has a conductive portion main body 3 made of an extruded material such as aluminum and a pair of conductors 6.

  The conductive portion main body 3 has a base wall portion 3a, side walls 3b bent at right angles from both side edges of the base wall portion 3a, and device support portions 3c that protrude from the inner side surfaces of the front end portions of the side walls 3b. In addition, both ends in the longitudinal direction of the conductive portion main body 3 are open. The inner surfaces of the side walls 3b face each other. The device support portion 3c is continuous at a right angle to the inner surface of the side wall 3b, and an opening 4 is formed between the leading edges facing each other. The opening 4 extends over the entire length of the conductive portion main body 3 and faces the central portion in the width direction of the inner side surface (lower surface in FIG. 4) of the base wall portion 3a. Reference numeral 5 denotes a grounding conductor attached to the center in the width direction of the inner side surface of the base wall 3a. This grounding conductor 5 can be omitted.

  The pair of conductors 6 is supported by an insulating material 7 fixed to the inner surface of the side wall 3b, and is provided in the conductive portion main body 3 so as to extend the entire length in the longitudinal direction of the conductive portion main body 3. These conductors 6 are disposed at the same height in the thickness direction (vertical direction in FIG. 4) of the conductive portion main body 3 and are exposed in the conductive portion main body 3, and this exposed portion is the conductive portion main body 3.

  A lighting device such as a spotlight (not shown) has a power receiving terminal that is slidably in contact with the conductor 6, and is slidably engaged with and suspended from the back surfaces of the pair of device support portions 3c. . Therefore, this lighting fixture can be used by moving the hanging position with respect to the conductive portion 2 to an arbitrary position in the longitudinal direction of the conductive portion 2.

  As shown in FIGS. 1 to 4, the connection portion 11 includes a connection portion main body 12, a pair of conductive bars 14, a pair of operation members 16, and a pair of contact fittings 18.

  The connection portion main body 12 is made of synthetic resin, has a length extending over the end portions in the longitudinal direction of the conductive portions 2 arranged adjacent to each other, and is formed so as to cover the outer surfaces of these end portions. Has been. A part of the side wall of the connecting portion main body 12 forms a cover portion 12a. The cover portion 12a is shorter than the entire length of the connection portion main body 12, for example, and is provided between these both end portions except for both ends in the longitudinal direction of the connection portion main body 12. A connection portion indicated by a symbol H in FIG. As shown in FIGS. 2 and 3, the main body 12 is formed at a height that covers the entire side of the side wall 3 b at the end of the conductive portion 2.

  The pair of conductive bars 14 are made of a conductive material that can be elastically deformed, specifically, a metal leaf spring, and these are attached to the connection portion main body 12. As shown in FIG. 1B, the length of the conductive bar 14 is shorter than the entire length of the connection portion main body 12 and longer than the length of the cover portion 12a. Therefore, these conductive bars 14 are attached to extend in the longitudinal direction of the connecting portion main body 12 at positions removed from the cover portion 12a, and the thickness direction of the connecting portion main body 12 (vertical direction in FIGS. 2 to 4). Are arranged at the same height, and face the width direction of the connecting portion main body 12 (the left-right direction in FIGS. 2 to 4). These conductive bars 14 are attached so as to be elastically deformable at both ends in the longitudinal direction, and for this reason, the back surface of the conductive bar 14 is supported by a rib (not shown) only at the center.

  As shown in FIG. 1, the pair of operation members 16 are rotatably attached to both ends in the longitudinal direction of the connection portion main body 12. These operation members 16 are made of synthetic resin, and have a linear operation groove 16a at one end side portion fitted to the front wall 12b of the connection portion main body 12 as shown in FIGS. A rotation operation is performed over a first position and a second position, which will be described later, through a tool such as a screwdriver inserted into the operation groove 16a. 2 to 4, reference numeral 16 b indicates an engaging portion of the operation member 16. The engagement portion 16b is a portion that contacts the back surface of the front wall 12b of the connection portion main body 12 and prevents the operation member 16 from falling off the connection portion main body 12, and has a circular shape.

  The operation member 16 has an insertion portion 16d that protrudes integrally from the center portion of the flange 16c and is inserted into the conductive portion 2. The operation member 16 has, for example, a circular flange 16c that defines an insertion depth by contacting the outer surface of the device support portion 3c when the connection portion main body 12 is combined with the end portion of the conductive portion 2.

  As shown in FIG. 1 (A), a pair of engaging convex portions 16e are integrally projected on the side surface of the insertion portion 16d. These engaging projections 16e are provided 180 degrees apart and can be inserted into and removed from the gap G. As shown in FIG. 3, in the state where the operation member 16 is disposed at the second position shifted by 90 degrees with respect to the first position, the pair of engaging convex portions 16e are inserted into the gap G, respectively, and the device support portion The operation member 16 is mechanically supported by the device support portion 3c by being engaged with the back surface of 3c. In other words, the connection part 11 is mechanically connected to the conductive part 2.

  As shown in FIG. 2, the width D of each engagement convex portion 16e is narrower than the mutual interval between the device support portions 3c, that is, the width B of the opening 4, and the conductive bar 14 and the insulating material 7 that supports this are mutually connected. Narrower than the interval. Further, the distance L (shown in FIG. 3) between the tips of the pair of engaging projections 16e is wider than the mutual distance between the device support portions 3c and wider than the mutual distance between the conductive bars 14 and the insulating material 7 that supports them. .

  Thereby, as shown in FIG. 2, in the state where the operation member 16 is disposed at the first position shifted by 90 degrees with respect to the second position, the insertion portion 16d having the pair of engagement convex portions 16e is The conductive part 2 can be inserted along the thickness direction of the conductive part 2 through the opening 4. In other words, the insertion portion 16 d of the operation member 16 can be inserted into the opening 4 in a direction orthogonal to the direction in which the conductive portion 2 and the conductor 6 extend and toward the base wall portion 3 a of the conductive portion 2. .

  The pair of contact fittings 18 form means for electrically connecting the conductors 6 in the adjacent conductive portions 2 together with the conductive bar 14, and are made of a metal leaf spring that is less elastically deformed than the conductive bar 14. And is attached to the operation member 16 at a distance of 180 degrees. As shown in FIG. 3, these contact fittings 18 have a first end portion 18 a and a second end portion 18 b that are substantially parallel to each other, and are formed in a substantially U-shape. As the operation member 16 is rotated, the first end portion 18 a is brought into contact with and separated from the conductor 6, and the second end portion 18 b is brought into contact with and separated from the conductive bar 14.

  The first end portion 18a disposed on one end portion side of the operation member 16 and the second end portion 18b disposed on the other end portion side of the operation member 16 are in the same direction as the engagement convex portion 16e. The engaging projection 16e is provided between the first end 18a and the second end 18b. Therefore, the contact fitting 18 is disposed in a direction perpendicular to the direction in which the conductive bar 14 extends, and consequently the direction in which the conductor 6 extends, as shown in FIG.

  As shown in FIG. 2, the width E of the contact fitting 18 is narrower than the width of the insertion portion 16d. The width of the insertion portion 16d is the same as the width D of the engaging convex portion 16e. Therefore, the insertion portion 16d can be inserted into the conductive portion 2 through the opening 4 as shown in FIG. 2 in a state where the operation member 16 is disposed at the first position. Therefore, in this state, the first end portion 18 a of the contact fitting 18 is separated from the conductor 6, and the second end portion 18 b of the contact fitting 18 is also separated from the conductive bar 14.

  As shown in FIG. 3, the first end 18 a of the contact fitting 18 is held in contact with the conductor 6 in a state where the operation member 16 is disposed at the second position, and the second end of the contact fitting 18 is maintained. The end portion 18b is kept in contact with the end portion of the conductive bar 14 in the longitudinal direction. These holdings are realized by the first end 18a being pressed against the conductor 6 by the elastic deformation of the contact fitting 18, and the second end 18b is electrically conductive by the elastic deformation of the end of the conductive bar 14. This is realized by relatively pressing the end of the bar 14. In addition, the code | symbol 16f in FIG. 3 has shown the escape groove provided in the operation member 16, and the elastic deformation of the contact metal fitting 18 is possible in this escape groove 16f.

  Next, a procedure for assembling the conductive device 1 will be described.

  First, all the conductive parts 2 to be used are arranged in a predetermined shape at an installation place such as a ceiling. In this case, the lighting fixture that needs to be passed through the open end of the conductive portion 2 is inserted along the longitudinal end surface of the conductive portion 2 and moved along the longitudinal direction of the conductive portion 2 to a desired position. This work is omitted when the lighting fixture can be attached to the conductive portion 2 through the opening 4 of the conductive portion 2, but this type of lighting fixture is finally assembled with the conductive device 1. After that, it is inserted upward along the thickness direction of the conductive portion 2 through the opening 4 of the conductive portion 2 and attached to an arbitrary position of the conductive portion 2.

  Thereafter, in a state where the operation member 16 of the connection portion 11 is disposed at the first position, the insertion portion 16d of the operation member 16 included in the connection portion 11 is replaced with the conductive portion of the conductive portion 2 that is attached to the ceiling or the like. It passes through the opening 4 of the conductive portion 2 upward so as to be perpendicular to the conductor 6 in the main body 3. As a result, the insertion portion 16d is inserted into the conductive portion 2, and at the same time, the connection portion 11 is covered over the opposing ends of the conductive portions 2 adjacent to each other. FIG. 2 shows a state where the connecting portion 11 is covered with the end portion of the conductive portion 2.

  In the state where the operation member 16 is disposed at the first position (set state), the engagement convex portion 16e of the insertion portion 16d, the first end portion 18a and the second end portion 18b of the contact fitting 18 are Since it arrange | positions so that it may protrude in the longitudinal direction of the connection part main body 12 and the electroconductive part main body 3, it does not become a hindrance at the time of covering the connection part 11 on the edge part of the electroconductive part 2. FIG.

  Next, the operation member 16 is rotated 90 degrees so that the operation groove 16a of the operation member 16 extends in the longitudinal direction of the connection portion main body 12, and the operation member 16 is arranged from the first position to the second position. . With this arrangement, the engagement protrusion 16e of the operation member 16 enters the gap G of the conductive portion body 3 and is engaged with the device support portion 3c from above, so that the connection portion 11 is connected to the conductive portion 2. Mechanically connected to the end.

  At the same time, the first end 18a of the contact fitting 18 comes into contact with the longitudinal end of the conductor 6 of the conductive portion 2, and the contact fitting 18 is elastically deformed with the progress of the contact. The electrical connection state in which the end portion 18a of the first electrode 18a is in elastic contact with the conductor 6 is maintained. At the same time, the second end portion 18b of the contact fitting 18 contacts the longitudinal end portion of the conductive bar 14 of the connecting portion 11, and the longitudinal end portion of the conductive bar 14 is elastically deformed as the contact proceeds. Therefore, the electrical connection state in which the end portion elastically contacts the second end portion 18b is maintained. Such a connection state is shown in FIG.

  Thereby, since the conductor 6 of the conductive portion 2 and the conductive bar 14 of the connecting portion 11 are electrically connected by the contact fitting 18, they correspond to the longitudinal direction of the conductive portions 2 that are attached to the ceiling or the like and adjacent to each other. The conductors 6 are electrically connected to each other through the connection portion 11.

  Of the conductive parts 2 arranged in a predetermined shape, the end part of the conductive part 2 whose end part is not covered by the connection part 11 is provided with an end cap made of an insulator that closes the opened end ( (Not shown).

  According to the assembly of the conductive device 1 described above, a plurality of conductive portions 2 can be placed in advance in a predetermined shape on a ceiling or the like, and adjacent conductive portions 2 can be mechanically and electrically connected to each other by the connection portion 11. . Therefore, even when the conductive portion 2 of the conductive device 1 is laid out in a complicated layout, it is not necessary to assemble the conductive device 1 in the whole or divided state on the ground side and then install it on the ceiling or the like. Thereby, the electroconductive apparatus 1 can be installed on a ceiling etc., without requiring many manual operations for installation. Further, the electrical connection around the connection portion 11 is also preferable in that no electric wire connection is required.

  Further, as is clear from the description of the assembly described above, in a state where the operation member 16 is disposed at the first position, the pair of contact fittings 18 of the connecting portion 11 is formed as a pair of conductors as shown in FIG. 6 is smaller than the mutual distance A of 6 and the width B of the opening 4. For this reason, when the insertion portion 16d of the operation member 16 to which the contact fitting 18 is attached is inserted through the opening 4 into the end portion of the conductive portion 2, the insertion portion 16d becomes the insulating material 7 and the conductor 6. It can be prevented from being inserted into the conductive part 2 by force.

  As a result, as the operating member 16 is rotated to the second position after the operation member 16 is inserted, a part of the insulating material 7 is peeled off and between the conductor 6 and the first end 18 a of the contact fitting 18. There is no possibility of being pinched, and there is no possibility that the contact fitting 18 is excessively elastically deformed and its springiness is lowered. Therefore, the reliability of the electrical connection between the conductor 6 and the contact metal fitting 18 is increased, in other words, the reliability of the electrical connection between the conductive portion 2 and the connection portion 11 can be improved.

  In addition, as described above, the contact fitting 18 of the connection portion 11 is inserted upward in the conductive portion 2 so as to be perpendicular to the conductor 6 in the conductive portion 2 in FIG. This is preferable.

  That is, when the connecting portion is attached to the end portion of the conductive portion from the open end face of the conductive portion, the contact fitting arranged along the longitudinal direction of the conductive portion is connected to the end portion of the conductive portion. Since the length corresponding to the insertion depth is occupied at the end of the conductive portion, the end cannot support the lighting fixture. Therefore, in such a thing, it is disadvantageous at the point to which the movable distance of the lighting fixture between the both ends of an electroconductive part becomes short, and in order to supplement this, it is necessary to use a longer electroconductive part.

  However, in the first embodiment, as described above, the operation member 16 is moved 90 degrees with the insertion portion 16d of the operation member 16 inserted upward into the opening 4 extending over the entire length in the longitudinal direction of the conductive portion 2. The connection part 11 is attached to the conductive part 2 by rotating. For this reason, it is not necessary to insert the connecting portion 11 from the open end of the conductive portion 2, so that the space occupied by the insertion portion 16 d of the connecting portion 11 at the end portion of the conductive portion 2 can be reduced and inserted. It is possible to provide the portion 16d as close to the longitudinal end of the conductive portion 2 as possible. Therefore, it is possible to secure a long movable distance of the luminaire between both end portions of the conductive portion 2.

  In addition, the connection portion main body 12 included in the connection portion 11 of the conductive device 1 having the above configuration covers the outer surface of the end portion of the conductive portion 2 that is disposed adjacently. Therefore, the installation accuracy of the conductive part 2 with respect to the installation place such as the ceiling is rough, and even if there is a gap between the opposite ends of the conductive part 2, it is covered with the connection part main body 12 and the appearance is lowered. You can avoid it. In addition, because of this, high accuracy is not required for the installation of the conductive portion 2, so that the installation workability of the conductive portion 2 at the installation location can be improved.

  A second embodiment of the present invention will be described with reference to FIGS. In the following description, since the conductive portion 2 has the same configuration as that described in the first embodiment, the same reference numerals are given and description thereof is omitted.

  The connection part 21 includes a connection part main body 22, a pair of contact fittings 24, and a pair of operation members 26.

  The connection portion main body 22 is made of synthetic resin, has a length extending between the end portions in the longitudinal direction of the conductive portions 2 arranged adjacent to each other, and is provided so as to cover the outer surfaces of these end portions. It has a U-shaped cross section. The side wall 22 a of the connection portion main body 22 is provided over the entire length of the connection portion main body 22, and the height of the side wall 22 a indicated by the symbol H in FIG. 6 is equal to the thickness of the conductive portion 2.

  The front wall 22b of the connection portion main body 22 can contact the outer surface (lower surface) of the device support portion 3c when the connection portion main body 22 is combined with the end of the conductive portion 2. On the inner side surface of the front wall 22b, as shown in FIG. 1, a metal fitting fixing portion 22c and a pair of metal fitting receiving portions 22d are integrally formed.

  The metal fitting fixing portion 22 c is provided at the center portion in the width direction of the connection portion main body 22 and at the center portion in the longitudinal direction of the connection portion main body 22, and is formed by a convex portion extending in the longitudinal direction of the connection portion main body 22. The bracket receiving portions 22 d are provided at the center in the width direction of the connection portion main body 22 and at both ends in the longitudinal direction of the connection portion main body 22, and these are also formed by convex portions extending in the longitudinal direction of the connection portion main body 22. However, the length is shorter than the metal fixture 22c. The width of the bracket receiving portion 22d and the width of the bracket fixing portion 22c are, for example, the same.

  A rotation angle restricting portion 22e is provided on the front wall 22b of the connecting portion main body 22 so as to be positioned between the metal fitting fixing portion 22c and the metal fitting receiving portion 22d. These rotation angle restricting portions 22e restrict the rotation angle of the operation member 26 to 90 degrees, and are formed by, for example, a groove that opens on the inner side surface of the front wall 22b.

  The pair of contact fittings 24 also serve as a conductive bar, and are made of a metal leaf spring that is a conductive material that can be elastically deformed. The length of the pair of contact fittings 24 is substantially the same as the entire length of the connection portion main body 22. Each of the end portions 24a in the longitudinal direction of the contact fitting 24 has a contact portion formed by bending, for example, a contact piece 24c. The contact portion may be formed of a member different from the contact fitting.

  The contact fitting 24 extends in the same direction as the conductor 6 and is attached to the connection portion main body 22. Specifically, the contact metal fitting 24 is attached with its central portion in the longitudinal direction fixed to the side surface of the metal fitting fixing portion 22c. Therefore, both end portions 24a of the contact metal fitting 24 can be elastically deformed, and these both end portions 24a are received by the side surfaces of the metal fitting receiving portion 22d by their own elastic force in an unloaded state. This state is shown in FIG. 5A, and in this state, the pair of contact fittings 24 are provided in parallel, and between the tips of the corresponding contact pieces 24c forming the maximum width thereof. The separation dimension W is narrower than the mutual distance between the pair of device support parts 3c included in the conductive part 2, that is, the width B of the opening 4, and narrower than the mutual distance between the conductive bar 14 and the insulating material 7 that supports the conductive bar 14.

  The pair of operation members 26 are rotatably mounted so as to be positioned at both ends in the longitudinal direction of the connection portion main body 22, specifically, between the metal fitting fixing portion 22 c and the metal fitting receiving portion 22 d. These operation members 26 are made of synthetic resin, and have a linear operation groove 26a at one end side portion fitted to the front wall 22b of the connection portion main body 22, and are inserted into the operation groove 26a. A rotation operation is performed over a first position and a second position described later via a tool such as a turning tool.

  In FIG. 6, reference numeral 26 b indicates an engaging portion of the operation member 26. The engaging portion 26b is in contact with the back surface of the front wall 22b of the connecting portion main body 22, and is a part responsible for preventing the operation member 26 from falling off the connecting portion main body 22 and regulating the rotation angle. Is formed. The engaging portion 26b hits one end or the other end of the rotation angle restricting portion 22e and restricts the rotation angle of the operation member 26 to 90 degrees. FIG. 5A shows a state in which the engaging portion 26b hits one end of the rotation angle restricting portion 22e and restricts the operating member 26 to the first position, and the engaging portion 26b hits the other end of the rotation angle restricting portion 22e and operates. A state where the member 26 is restricted to the second position is shown in FIG.

  The operation member 26 has an insertion portion 26 d that is inserted into the conductive portion 2. The insertion portion 26d is formed with a substantially rectangular engagement convex portion 26e that integrally protrudes from the side surface. Both ends in the longitudinal direction of the engaging convex portion 26e can be inserted into and removed from the gap G provided in the conductive portion 2. As shown in FIG. 6, in a state where the operation member 26 is arranged at the second position shifted by 90 degrees with respect to the first position, both end portions of the engaging convex portion 26e are inserted into the gap G, respectively, to support the device. It is adapted to be engaged with the back surface of the portion 3c. By this engagement, the operation member 26 is mechanically supported by the device support portion 3c. In other words, the connection portion 21 is mechanically connected to the conductive portion 2.

  As shown in FIG. 5 (B), the width I of the engaging convex portion 26e is narrower than the mutual interval of the device support portions 3c, that is, the width B of the opening 4. At the same time, the length L of the engaging projection 26 e shown in FIG. 5A is wider than the width B of the opening 4. Therefore, as shown in FIG. 8, in the state where the operation member 26 is disposed at the first position shifted by 90 degrees with respect to the second position, the insertion portion 26 d having the engagement convex portion 26 e is connected to the conductive portion 2. It can be inserted vertically upward along the thickness direction of the conductive portion 2 through the opening 4. In other words, the insertion portion 26d of the operation member 26 can be inserted into the opening 4 in a direction orthogonal to the direction in which the conductive portion 2 and the conductor 6 extend and toward the base wall portion 3a of the conductive portion 2. .

  The insertion portion 26d of the operation member 26 has a cam portion 26c that protrudes integrally with the central portion of the engagement convex portion 26e. The cam portion 26c has an oval shape, and is provided so that its longitudinal direction is orthogonal to the operation groove 26a when viewed from the front as shown in FIGS. The width of the cam portion 26c is the width of the metal fitting fixing portion 22c and the metal fitting receiving portion 22d, in other words, the opposite end portions 24a of the pair of contact metal fittings 24 are received by the metal fitting receiving portion 22d as shown in FIG. In this state, it is shorter than the mutual interval between the opposite end portions 24a. The length between both longitudinal ends of the cam portion 26c is longer than the widths of the metal fitting fixing portion 22c and the metal fitting receiving portion 22d.

  The cam portion 26c is inserted between the opposed end portions 24a of the pair of contact fittings 24, and the opposed ends of the pair of contact fittings 24 when the operation member 26 is disposed at the second position. The portions 24a are elastically deformed to push apart in a direction away from each other.

  Next, a procedure for assembling the conductive device 1 according to the second embodiment will be described.

  First, all the conductive parts 2 to be used are arranged in a predetermined shape at an installation place such as a ceiling. In this case, the lighting fixture that needs to be passed through the open end of the conductive portion 2 is inserted from the longitudinal end of the conductive portion 2 and moved along the longitudinal direction of the conductive portion 2 to a desired position. This work is omitted when the lighting fixture can be attached to the conductive portion 2 through the opening 4 of the conductive portion 2, but this type of lighting fixture is finally assembled with the conductive device 1. After that, it is inserted along the thickness direction of the conductive portion 2 through the opening 4 of the conductive portion 2 and attached to an arbitrary position of the conductive portion 2.

  Thereafter, in a state where the operation member 26 of the connection portion 21 is disposed at the first position, the insertion portion 26d of the operation member 26 included in the connection portion 21 is replaced with the conductive portion of the conductive portion 2 that is attached to the ceiling or the like. It passes through the opening 4 of the conductive portion 2 upward so as to be perpendicular to the conductor 6 in the main body 3. Accordingly, the insertion portion 26d and the pair of contact fittings 24 in parallel with each other are inserted into the conductive portion 2 through the opening 4, and opposite ends of the conductive portions 2 adjacent to each other. The connecting portion 21 is covered. FIG. 7 shows a state (set state) in which the connection portion 21 is thus covered on the end portion of the conductive portion 2.

  In the state where the operation member 26 is disposed at the first position, the engagement convex portion 26e of the insertion portion 26d is arranged in the longitudinal direction of the connection portion main body 22 and the conductive portion main body 3 as shown in FIG. It is provided along. Similarly, as shown in FIG. 7, the cam portion 26c of the insertion portion 26d inserted between the opposite end portions 24a of the pair of contact fittings 24 is provided at a position where the opposite end portions 24a are not pushed open. ing. As a result, the pair of contact fittings 24 are held in parallel with each other, and the opposite end portions 24a hold a space narrower than the width B of the opening 4 due to their own elasticity. Therefore, the engaging protrusion 26e and the pair of contact fittings 24 do not hinder the connection portion 21 from being put on the end portion of the conductive portion 2.

  Therefore, the insertion portion 26d is inserted into the conductive portion 2 until the front wall 22b of the connection portion main body 22 hits the device support portion 3c by the operation described above.

  Next, as shown in FIG. 5B, the operation member 26 is rotated 90 degrees so that the operation groove 26a of the operation member 26 extends in the longitudinal direction of the connection portion main body 22, and the operation member 26 is moved to the first position. Arrange from the position to the second position. In this case, the rotation of the operation member 26 is restricted to 90 degrees by the engagement portion 26b of the operation member 26 hitting the rotation angle restricting portion 22e of the connection portion main body 22, so that the operation member 26 is appropriately rotated. This can be reliably arranged at the second position.

  With this arrangement, the engagement convex portion 16e of the operation member 26 enters the gap G of the conductive portion main body 3 and is engaged with the device support portion 3c from above, so that the connection portion 21 is connected to the conductive portion 2. Mechanically connected to the end.

  At the same time, the cam portion 26c of the insertion portion 26d rotated 90 degrees causes the opposite end portions 24a of the pair of contact fittings 24 to move away from each other while being elastically deformed as shown in FIG. 5B. Push open. Therefore, the distance between the contact pieces 24c formed on the end 24a of the contact fitting 24 is wider than the width B of the opening 4 and the mutual interval A between the conductors 6 of the conductive portion 2, and the contact pieces 24c are formed in the conductor 6. The electrical connection state in which the contact piece 24c elastically contacts the conductor 6 is maintained as the contact proceeds. Such a connection state is shown in FIG.

  Thereby, since the conductor 6 of the conductive part 2 and the contact metal fitting 24 of the connection part 21 are electrically connected, the conductors 6 corresponding to the longitudinal direction of the conductive parts 2 that are preceded by a ceiling or the like and are adjacent to each other. Are electrically connected through the connecting portion 21.

  Of the conductive parts 2 arranged in a predetermined shape, the end part of the conductive part 2 whose end part is not covered with the connection part 21 is provided with an end cap made of an insulator that closes the opened end surface ( (Not shown).

  According to the assembly of the conductive device 1 described above, a plurality of conductive portions 2 can be placed in advance in a predetermined shape on a ceiling or the like, and adjacent conductive portions 2 can be mechanically and electrically connected to each other by the connection portion 21. . Therefore, even when the conductive portion 2 of the conductive device 1 is laid out in a complicated layout, it is not necessary to assemble the conductive device 1 in the whole or divided state on the ground side and then install it on the ceiling or the like. Thereby, the electroconductive apparatus 1 can be installed on a ceiling etc., without requiring many manual operations for installation. Further, the electrical connection around the connecting portion 21 is also preferable in that a wire connection is not required.

  Further, as is clear from the description of the assembly described above, in the state where the operation member 26 is disposed at the first position, the pair of contact fittings 24 and the insertion portion 26d of the connection portion 21 are as shown in FIG. The distance between the pair of conductors 6 and the width B of the opening 4 is narrower. Therefore, when the contact fitting 24 and the insertion portion 26d attached to the connection portion main body 22 are inserted into the end portion of the conductive portion 2 through the opening 4, the contact fitting 24 and the insertion portion 26d are insulated from each other. 7 and the conductor 6 can be prevented from being inserted into the conductive portion 2 by force.

  As a result, as the operating member 26 is rotated to the second position after the operation member 26 is inserted, a part of the insulating material 7 is peeled off, and the contact piece 24 c formed on the conductor 6 and the end 24 a of the contact fitting 24. There is no possibility that the contact fitting 24 is excessively elastically deformed and its springiness is not lowered. Therefore, the reliability of the electrical connection between the conductor 6 and the contact fitting 24 is increased, in other words, the reliability of the electrical connection between the conductive portion 2 and the connection portion 21 can be improved.

  In addition, the connection portion main body 22 included in the connection portion 21 of the conductive device 1 having the above configuration covers the outer surface of the end portion of the conductive portion 2 that is disposed adjacently. Therefore, the installation accuracy of the conductive part 2 relative to the installation place such as the ceiling is rough, and even if there is a gap between the opposite ends of the conductive part 2, it is covered with the connection part main body 22 and the appearance is lowered. You can avoid it. In addition, because of this, high accuracy is not required for the installation of the conductive portion 2, so that the installation workability of the conductive portion 2 at the installation location can be improved.

  A third embodiment of the present invention will be described with reference to FIGS. In the following description, the same components as those in the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the third embodiment, as the operating member is arranged from the first position to the second position by the rotation operation, the mechanical connection is made simultaneously with the electrical connection of the connection part to the conductive part. Compared with the second embodiment, the point that these connections are made individually is different from the second embodiment.

  Therefore, in the third embodiment, each of the operation member 27 responsible for the electrical connection and the other operation member 28 responsible for the mechanical connection is provided at both ends in the longitudinal direction of the connection portion main body 22. Is mounted between the bracket fixing portion 22c and the bracket receiving portion 22d so as to be rotatable. Further, other rotation angle restricting portions 22f are provided between the metal fitting fixing portion 22c and the metal fitting receiving portion 22d of the connection portion main body 22, respectively. The other rotation angle restricting portion 22f restricts the rotation angle of the other operation member 28 to 90 degrees. For example, the rotation angle restricting portion 22f is formed by a groove opened on the inner surface of the front wall 22b. The configuration is the same as that of the restricting portion 22e.

  The pair of operation members 27 has a configuration in which the cam portion of the operation member described in the second embodiment is omitted.

  That is, as shown in FIGS. 13A and 13B, the operation member 27 made of synthetic resin has a linear operation groove 27a at one end side portion fitted to the front wall 22b of the connection portion main body 22. The rotation operation is performed over a first position and a second position, which will be described later, via a tool such as a screwdriver inserted into the operation groove 27a.

  The engaging portion 27b of the operating member 27 is in contact with the back surface of the front wall 22b of the connecting portion main body 22, and is a part responsible for preventing the operating member 27 from falling off the connecting portion main body 22 and regulating the rotation angle. It is formed with the convex part. The engaging portion 27b hits one end or the other end of the rotation angle restricting portion 22e and restricts the rotation angle of the operation member 27 to 90 degrees. The state of the operating member 27 when the engaging portion 27b hits one end of the rotation angle restricting portion 22e and the operating member 27 is disposed at the first position is shown in FIG. 9, and the engaging portion 27b is the rotation angle restricting portion 22e. FIGS. 10 and 11 show the state of the operation member 27 when the operation member 27 is disposed at the second position by hitting the other end.

  As shown in FIG. 13, the operation member 27 has an insertion portion 27 d that is inserted into the conductive portion 2. The insertion portion 27d has a cam portion 27c on the distal end side. As shown in FIGS. 9 to 11, the shape of the cam portion 27 c viewed from the front is an oval shape, and the longitudinal direction thereof is provided to be orthogonal to the operation groove 27 a when viewed from the front. The width of the cam portion 27c is the width of the metal fitting fixing portion 22c and the metal fitting receiving portion 22d, in other words, the opposite end portions 24a of the pair of contact metal fittings 24 are received by the metal fitting receiving portion 22d as shown in FIGS. It is narrower than the mutual space | interval of the edge parts 24a which faced each other in the state which is carried out. The length between both ends in the longitudinal direction of the cam portion 27c is longer than the widths of the metal fitting fixing portion 22c and the metal fitting receiving portion 22d.

  The cam portion 27c is inserted between the opposed end portions 24a of the pair of contact fittings 24, and the opposed ends of the pair of contact fittings 24 when the operation member 27 is disposed at the second position. The portions 24a are elastically deformed to push apart in a direction away from each other.

  The other operation member 28 has a configuration in which the engagement convex portion of the operation member described in the second embodiment is omitted.

  That is, as shown in FIG. 12, the other operation member 28 made of synthetic resin has a linear operation groove 28a at one end side portion fitted to the front wall 22b of the connection portion main body 22, and this operation groove It is rotated over a first position and a second position, which will be described later, via a tool such as a screwdriver inserted into 28a.

  The engaging portion 28b of the other operation member 28 is in contact with the back surface of the front wall 22b of the connection portion main body 22, and is a part responsible for preventing the other operation member 28 from falling off the connection portion main body 22 and regulating the rotation angle. The fan-shaped convex portion is formed. The engaging portion 28b hits one end or the other end of the other rotation angle restricting portion 22f and restricts the rotation angle of the other operation member 28 to 90 degrees. The state of the other operating member 28 when the engaging portion 28b hits one end of the other rotation angle restricting portion 22f and the other operating member 28 is disposed at the first position is shown in FIGS. The state of the other operation member 28 when the part 28b hits the other end of the other rotation angle restricting part 22f and the other operation member 28 is disposed at the second position is shown in FIG.

  As shown in FIG. 12, the other operation member 28 has an insertion portion 28 d that is inserted into the conductive portion 2. The insertion portion 28d is formed with a substantially rectangular engaging convex portion 28e that integrally projects from the side surface. Both end portions in the longitudinal direction of the engaging convex portion 28e can be inserted into and removed from the gap G provided in the conductive portion 2. As shown in FIG. 12A, in a state where the other operation member 28 is disposed at the second position shifted by 90 degrees with respect to the first position, both end portions of the engagement convex portion 28e are respectively in the gap G. It is inserted and engaged with the back surface of the apparatus support part 3c. Due to this engagement, the other operation member 28 is mechanically supported by the device support 3c. In other words, the connection portion 21 is mechanically connected to the conductive portion 2.

  As shown in FIG. 11, the width I of the engaging convex portion 28 e is narrower than the mutual interval between the device support portions 3 c, that is, the width B of the opening 4. At the same time, the length L of the engaging projection 28 e shown in FIG. 9 is wider than the width B of the opening 4. Therefore, as shown in FIG. 9, in the state where the other operation member 28 is disposed at the first position shifted by 90 degrees with respect to the second position, the insertion portion 28d having the engagement convex portion 28e is electrically conductive. It can be inserted into the part 2 along the thickness direction of the conductive part 2 through the opening 4. In other words, the insertion portion 28d of the other operation member 28 can be inserted into the opening 4 in a direction orthogonal to the direction in which the conductive portion 2 and the conductor 6 extend and toward the base wall portion 3a of the conductive portion 2. It is.

  Next, a procedure for assembling the conductive device 1 according to the third embodiment will be described.

  First, all the conductive parts 2 to be used are arranged in a predetermined shape at an installation place such as a ceiling. In this case, the lighting fixture that needs to be passed through the open end of the conductive portion 2 is inserted from the longitudinal end of the conductive portion 2 and moved along the longitudinal direction of the conductive portion 2 to a desired position. This work is omitted when the lighting fixture can be attached to the conductive portion 2 through the opening 4 of the conductive portion 2, but this type of lighting fixture is finally assembled with the conductive device 1. After that, it is inserted along the thickness direction of the conductive portion 2 through the opening 4 of the conductive portion 2 and attached to an arbitrary position of the conductive portion 2.

  Thereafter, in a state where the operation member 27 and the other operation member 28 of the connection portion 21 are arranged at the first position, the insertion portion 27d of the operation member 27 and the insertion portion 28d of the other operation member 28 are connected to the ceiling or the like. The conductive part 2 is passed through the opening 4 of the conductive part 2 upward so as to be perpendicular to the conductor 6 in the conductive part main body 3 of the conductive part 2. Thereby, as shown in FIG. 13B, a pair of contact fittings 24 in parallel with each other is inserted into the conductive portion 2 through the opening 4, and the conductive portions 2 adjacent to each other are inserted. The connection part 21 is covered over the opposite ends. A set state in which the connection portion 21 is thus covered on the end portion of the conductive portion 2 is shown in FIGS. 9, 12B, and 13B.

  In the state where the other operation member 28 is disposed at the first position, the engaging convex portion 28e of the insertion portion 28d extends along the longitudinal direction of the connection portion main body 22 and the conductive portion main body 3 as shown in FIG. It is provided as follows. Similarly, in the state where the operation member 27 is disposed at the first position, the cam portion 27c of the insertion portion 27d inserted between the opposite end portions 24a of the pair of contact fittings 24 as shown in FIG. It is provided at a position where the opposite end portions 24a are not pushed open. As a result, the pair of contact fittings 24 are held in parallel with each other, and the opposite end portions 24a hold a space narrower than the width B of the opening 4 due to their own elasticity. Therefore, the engaging convex portion 28e and the pair of contact fittings 24 do not become an obstacle when the connecting portion 21 is put on the end portion of the conductive portion 2.

  Therefore, the insertion portions 27d and 28d are inserted into the conductive portion 2 until the front wall 22b of the connection portion main body 22 hits the device support portion 3c by the operation described above.

  Next, as shown in FIG. 10, the other operation member 28 is rotated 90 degrees so that the operation groove 28a of the other operation member 28 extends in the longitudinal direction of the connection portion main body 22, and the other operation member 28 is moved to the first position. It arrange | positions from the position of 1 to the 2nd position. In this case, since the engaging portion 28b of the other operation member 28 hits the end of the other rotation angle restricting portion 22f of the connecting portion main body 22, the rotation of the other operation member 28 is restricted to 90 degrees. The member 28 is properly rotated and can be reliably placed in the second position.

  With this arrangement, the engagement projection 28e of the other operation member 28 enters the gap G of the conductive portion body 3 and is engaged with the device support portion 3c from above, so that the connection portion 21 is connected to the conductive portion. 2 is mechanically connected to the end. This state is shown in FIG.

  Thereafter, as shown in FIG. 11, the operation member 27 is rotated 90 degrees so that the operation groove 27a of the operation member 27 extends in the longitudinal direction of the connection portion main body 22, and the operation member 27 is moved from the first position to the second position. Place at the position. In this case, since the engaging portion 27b of the operation member 27 hits the end of the rotation angle restricting portion 22e of the connection portion main body 22, the rotation of the operation member 27 is restricted to 90 degrees, so that the operation member 27 is appropriately rotated. This can be reliably arranged at the second position.

  With such 90-degree rotation, the cam portion 27c of the insertion portion 27d pushes open the opposing end portions 24a of the pair of contact fittings 24 in a direction away from each other while being elastically deformed as shown in FIG. Therefore, the space between the contact pieces 24c formed at the end 24a is wider than the width B of the opening 4 and the distance A between the conductors 6 of the conductive portion 2, and the contact pieces 24c are arranged in the longitudinal direction of the conductor 6. An electrical connection state in which the contact piece 24c is in elastic contact with the conductor 6 is maintained as the end portion comes into contact with the progress of the contact. Such a connection state is shown in FIG.

  Thereby, since the conductor 6 of the conductive part 2 and the contact metal fitting 24 of the connection part 21 are electrically connected, the conductors 6 corresponding to the longitudinal direction of the conductive parts 2 that are preceded by a ceiling or the like and are adjacent to each other. Are electrically connected through the connecting portion 21.

  Of the conductive parts 2 arranged in a predetermined shape, the end part of the conductive part 2 whose end part is not covered with the connection part 21 is an end made of an insulator that closes the open end. A cap (not shown) is attached.

  According to the assembly of the conductive device 1 described above, a plurality of conductive portions 2 are placed in advance in a predetermined shape on a ceiling or the like, and after being mechanically connected to the end portions of the conductive portions 2 by the connecting portions 21, they are adjacent to each other. The electrically conductive parts 2 can be electrically connected by the connecting part 21. Therefore, even when the conductive portion 2 of the conductive device 1 is laid out in a complicated layout, it is not necessary to assemble the conductive device 1 in the whole or divided state on the ground side and then install it on the ceiling or the like. Thereby, the electroconductive apparatus 1 can be installed on a ceiling etc., without requiring many manual operations for installation. Further, the electrical connection around the connecting portion 21 is also preferable in that a wire connection is not required.

  Further, as is clear from the description of the assembly described above, in a state where the operation member 27 and the other operation member 28 are disposed at the first position, the pair of contact fittings 24 and the insertion portions 27d and 28d of the connection portion 21 are provided. However, the distance between the pair of conductors 6 and the width B of the opening 4 is narrower. For this reason, when the contact fitting 24 and the insertion portions 27d and 28d attached to the connection portion main body 22 are inserted into the end portion of the conductive portion 2, the contact fitting 24 and the insertion portions 27d and 28d are connected to the insulating material 7 and the conductive portion. Competing with the body 6 can be prevented from being inserted into the conductive portion 2 by force.

  Thereby, after inserting the operation member 27 and the other operation member 28, as these are rotated to the second position, a part of the insulating material 7 is peeled off and the conductor 6 and the end portion of the contact fitting 24 are removed. There is no possibility of being pinched between the contact piece 24c formed on 24a, and there is no possibility that the contact fitting 24 is excessively elastically deformed and its springiness is lowered. Therefore, the reliability of the electrical connection between the conductor 6 and the contact fitting 24 is increased, in other words, the reliability of the electrical connection between the conductive portion 2 and the connection portion 21 can be improved.

  In addition, the connection portion main body 22 included in the connection portion 21 of the conductive device 1 having the above configuration covers the outer surface of the end portion of the conductive portion 2 that is disposed adjacently. Therefore, the installation accuracy of the conductive part 2 relative to the installation location such as the ceiling is rough, and even if there is a gap between the opposite ends of the conductive part 2, it is covered with the connection part main body 22 and the appearance is lowered. You can avoid it. In addition, because of this, high accuracy is not required for the installation of the conductive portion 2, so that the installation workability of the conductive portion 2 at the installation location can be improved.

  A fourth embodiment of the present invention will be described with reference to FIGS.

  The connection portion indicated by reference numeral 31 in these drawings includes a connection portion main body 32, a metal fitting holder 33, a pair of contact metal fittings 34, one operation member 35, and a pair of urging bodies 36. The connecting portion 31 is inserted into an end portion of the conductive portion 2 (the configuration is the same as that described in the first embodiment) from an end face opened in the longitudinal direction of the conductive portion 2. These are provided over the longitudinal ends of the conductive portions 2 arranged adjacent to each other.

  The connection portion main body 32 is made of metal, and has fixing holes 32a at both ends in the longitudinal direction. The connecting portion main body 32 is inserted in the longitudinal direction of the conductive portion 2 by a screw 38 inserted through the opening 4 of the conductive portion 2 and screwed into the base wall portion 3a of the conductive portion 2 through the fixing hole 32a. Fixed to the end.

  The metal fitting holder 33 is made of a synthetic resin, and is attached to the back surface of the connection portion main body 32, and both side edges project out so as to cover both side edges of the connection portion main body 32. A pair of contact metal fittings 34 are supported by the metal fitting holder 33 so as to be movable in the width direction of the connection portion main body 32.

  The length of the pair of contact fittings 34 is shorter than the total length of the fitting holder 33. These contact fittings 34 are formed of metal leaf springs that can be elastically deformed and have conductivity. The pair of contact fittings 34 has contact portions, for example, contact pieces 34a formed by bending the end portions at both ends in the longitudinal direction. The contact pieces 34a are inserted into the guide grooves 33a provided in the metal fitting holder 33 corresponding to these individually, and are regulated so as to be translated by these guide grooves 33a.

  The operation member 35 is rotatably attached to the central portion in the longitudinal direction of the connection portion main body 32 and is held so as not to drop off by a retaining means (not shown). The operation member 35 is made of synthetic resin and has a linear operation groove 35a exposed on the front surface of the connection portion main body 32. The operation member 35 is inserted through a tool such as a screwdriver inserted into the operation groove 35a. A rotation operation is performed between the first position and the second position.

  The operation member 35 has an upward insertion portion 35 d that is inserted into the conductive portion 2. This insertion part 35d has a cam part 35c integrally. The cam portion 35c has an oval shape, and its longitudinal direction is provided in parallel with the operation groove 35a when viewed from the front as shown in FIGS. 14 (A) and 15 (A). The cam portion 35c is inserted between a pair of contact fittings 34 facing each other. In the state where the operation member 35 is disposed at the second position shown in FIGS. 15A and 15B, the pair of contact fittings 34 are pushed away from each other by the cam portion 35c.

  The pair of urging bodies 36 is made of, for example, a spring, and is provided by urging the pair of contact fittings 34 in a direction approaching each other. Therefore, in a state where the operation member 35 is disposed at the first position shown in FIGS. 14A and 14B, the biasing member 36 causes the pair of contact fittings 34 to sandwich the cam portion 35c therebetween. It has been moved. Furthermore, in this state, the mutual distance K between the contact pieces 34 a which is the maximum separation distance between the pair of contact fittings 34 is held narrower than the mutual distance A between the pair of conductors 6 in the conductive portion 2.

  Next, a procedure for assembling the conductive device 1 according to the fourth embodiment will be described.

  First, the operation member 35 of the connection part 31 is arrange | positioned in a 1st position. The mutual relationship between the operation member 35 arranged at the first position and the pair of contact fittings 34 is shown in FIGS. 14A and 14B, and the corresponding contact of the pair of contact fittings 34 in this state. The mutual distance K between the pieces 34a is the narrowest.

  Thereafter, one end portion of the connecting portion 31 is inserted along the longitudinal direction of the conductive portion 2 into one longitudinal end portion of the two conductive portions 2 to be installed from the opened end face. At the same time, the other end portion of the connecting portion 31 is also inserted along the longitudinal direction of the conductive portion 2 from the opened end face into the longitudinal end portion of the other conductive portion 2. Such a set state is shown in FIG. Subsequently, the connecting portion main body 32 is mechanically fixed to the end portions of the two conductive portions 2 using screws 38. In this case, it is preferable in terms of appearance if the adjacent end faces of the two conductive parts 2 to be installed are brought into contact with each other. Further, due to the insertion, the contact pieces 34 a of the pair of contact fittings 34 are arranged so as to be close to the longitudinal ends of the pair of conductors 6 in the conductive portion 2.

  Next, the operation member 35 of the connection portion 31 is rotated 90 degrees and disposed at the second position. The mutual relationship between the operation member 35 arranged at the second position and the pair of contact fittings 34 is shown in FIGS. 15A and 15B, and the corresponding contact of the pair of contact fittings 34 in this state. The mutual interval K between the pieces 34a is most widened by the cam portion 35c. As the mutual distance K between the pair of contact fittings 34 is increased in this way, the contact piece 34a is brought into contact with the longitudinal ends of the pair of conductors 6 in the conductive portion 2, thereby increasing the mutual distance K. Accordingly, the end of the contact fitting 34 in the longitudinal direction is elastically deformed and the contact is maintained.

  As a result, the conductor 6 of the conductive portion 2 and the contact fitting 34 of the connection portion 31 are electrically connected, so that the conductors 6 corresponding to the longitudinal direction of the conductive portions 2 adjacent to each other pass through the connection portion 31. Are electrically connected. Of the conductive parts 2 arranged in a predetermined shape, an end cap made of an insulating material that closes the open end is provided at the end of the conductive part 2 whose end is not connected by the connection part 31. Is attached (not shown).

  According to the assembly of the conductive device 1 described above, in the state where the operation member 35 is disposed at the first position, the mutual distance K between the pair of contact fittings 34 of the connection portion 31 is equal to the mutual distance between the pair of conductors 6. It is in a narrower state. For this reason, when the connecting portion 31 is inserted into the end portion of the conductive portion 2 from the opened end, the contact fittings 34 are forcibly inserted into the conductive portion 2 in competition with the insulating material 7 and the conductor 6. There is nothing.

  Accordingly, as the operation member 35 is rotated to the second position, a part of the insulating material 7 is peeled off and may be sandwiched between the conductor 6 and the contact piece 34 a formed on the contact fitting 34. In addition, there is no possibility that the contact fitting 34 is excessively elastically deformed and its springiness is lowered. Therefore, the reliability of the electrical connection between the conductor 6 and the contact metal fitting 34 is increased, in other words, the reliability of the electrical connection between the conductive portion 2 and the connection portion 31 can be improved.

  When the connecting portion 31 is inserted into the end portion of the conductive portion 2 as the connecting portion 31 in which the urging body 36 is omitted in the fourth embodiment, the mutual distance K between the pair of contact fittings 34 is The pair of contact fittings 34 are moved by hand so as to be closer to each other so that the distance between the conductors 6 becomes narrower. In this state, the connecting portion 31 is connected to the end portion in the longitudinal direction of the conductive portion 2 from the opened end. Just plug it in.

  A fifth embodiment of the present invention will be described with reference to FIGS. In the following description, the same components as those in the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the fifth embodiment, the operating member is divided into an upper part and a lower part, and the lower part is provided so as to be movable up and down (in other words, movable in the thickness direction of the conductive part) and urged downward. The second embodiment is different from the second embodiment in that an urging force for returning the urging force to the first position is given and the lower portion of the operation member can be held at the second position against the urging force.

  Specifically, as shown in FIGS. 16 and 21, the operation member 26 is divided into an insertion portion 26d that forms the upper portion and an operation portion 26g that forms the lower portion. As described in the second embodiment, the insertion portion 26d is formed with the cam portion 26c and the engaging convex portion 26e. In addition, the insertion portion 26d is provided with a connecting hole 26h that opens to the center of the lower surface. The connection hole 26h is non-circular, and is formed, for example, as a square hole, specifically, a square hole.

  The operation portion 26g is provided with a linear operation groove 26a opened on the lower surface thereof. Unlike the second embodiment, the operation groove 26a extends in the same direction as the longitudinal direction (the direction in which the long axis of the ellipse extends) of the substantially oval cam portion 26c as shown in FIGS. Is formed. At the same time, an engaging portion 26b is provided integrally with the operation portion 26g. The engaging portion 26b is formed as a substantially rectangular convex portion as shown in FIG. 18 and the like, and protrudes in a direction in which the operation groove 26a extends as shown in FIGS.

  Furthermore, an upward connecting convex portion 26f is integrally projected at the center of the upper surface of the operation portion 26g. The connecting convex portion 26f has a shape corresponding to the connecting hole 26h, and the cross-sectional shape in the direction orthogonal to the protruding direction is non-circular. Accordingly, as shown in FIGS. 18 and 23, the connecting convex portion 26f is formed in, for example, a rectangular column shape. The connecting convex portion 26f is fitted in the connecting hole 26h so as to be movable up and down.

  As shown in FIGS. 16 and 21, for example, a coil spring 41 is provided as an urging member between the insertion portion 26d and the operation portion 26g, specifically, the inner surface of the connection hole 26h and the upper end of the connection convex portion 26f. It is sandwiched between them. The coil spring 31 always urges the operation portion 26g downward. Thereby, the engaging part 26b is always pressed against the rotation angle restricting part 22e of the connecting part main body 22. However, since the rotation angle restricting portion 22e receives the engaging portion 26b, the operating portion 26g is supported on the front wall 22b of the connecting portion main body 22 so that the operating portion 26g is not dropped by the biasing force of the coil spring 41. ing.

  As described above in the second embodiment, the rotation angle restricting portion 22e has an arc shape in plan view and restricts the rotation angle of the operation member 26 to 90 degrees. Specifically, as shown in FIGS. 18 and 23, the operation member 26 having the operation portion 26g is positioned at the first position at one end 42 of the rotation angle restricting portion 22e, and the other end portion of the rotation angle restricting portion 22e. The operating member 26 is positioned at the second position by the holding portion 43 formed in the above.

  The rotation angle restricting portion 22e is formed by a groove opened on the back surface of the front wall 22b. In the present embodiment, the rotation angle restricting portion 22e further includes a holding portion 43 as shown in FIGS. The holding portion 43 is formed by a depressed portion formed deeper at the other end portion. The engaging portion 26 b is fitted into the holding portion 43 and can be engaged. The engaging portion 26b can be inserted into and removed from the holding portion 43 as the operation portion 26g is moved up and down.

  As shown in FIGS. 18, 19, 23, and 24, the operating portion 26g is biased to the first position by a return member, for example, a return coil spring 44. The return coil spring 44 is provided with both ends thereof connected to the operation portion 26g and a fixed portion, for example, the back surface of the front wall 22b.

  Next, a procedure for assembling the conductive device 1 according to the fifth embodiment will be described.

  First, all the conductive parts 2 to be used are arranged in a predetermined shape at an installation place such as a ceiling. In this case, the lighting fixture that needs to be passed through the open end of the conductive portion 2 is inserted from the longitudinal end of the conductive portion 2 and moved along the longitudinal direction of the conductive portion 2 to a desired position. This work is omitted when the lighting fixture can be attached to the conductive portion 2 through the opening 4 of the conductive portion 2, but this type of lighting fixture is finally assembled with the conductive device 1. After that, it is inserted along the thickness direction of the conductive portion 2 through the opening 4 of the conductive portion 2 and attached to an arbitrary position of the conductive portion 2.

  Thereafter, in a state where the operation member 26 of the connection portion 21 is disposed at the first position, the insertion portion 26d of the operation member 26 included in the connection portion 21 is replaced with the conductive portion of the conductive portion 2 that is attached to the ceiling or the like. It passes through the opening 4 of the conductive portion 2 upward so as to be perpendicular to the conductor 6 in the main body 3. Accordingly, the insertion portion 26d and the pair of contact fittings 24 in parallel with each other are inserted into the conductive portion 2 through the opening 4, and opposite ends of the conductive portions 2 adjacent to each other. The connecting portion 21 is covered.

  FIG. 16 shows a state (set state) where the connection portion 21 is thus covered on the end portion of the conductive portion 2. In this state, since the operation member 26 is disposed at the first position, the engagement portion 26b of the operation portion 26g is positioned in the shallow groove portion of the rotation angle restricting portion 22e and positioned at one end 42 as shown in FIG. Has been. Accordingly, as shown in FIG. 16, the operation portion 26 g is held at a height position where the coil spring 41 is compressed and raised, and the lower surface thereof is located deeper than the lower surface of the connection portion main body 22. The operation member 26 at such a height position is referred to as being in an OFF state.

  In the state where the operation member 26 is disposed at the first position, the engagement convex portion 26e of the insertion portion 26d is along the longitudinal direction of the connection portion main body 22 and the conductive portion main body 3 as shown in FIG. Is provided. At the same time, as shown in FIG. 17, the cam portion 26c of the insertion portion 26d inserted between the opposite end portions 24a of the pair of contact fittings 24 is provided at a position where the opposite end portions 24a are not pushed open. ing. As a result, the pair of contact fittings 24 are held in parallel with each other, and the opposite end portions 24a hold a space narrower than the width B of the opening 4 due to their own elasticity. Therefore, the engaging protrusion 26e and the pair of contact fittings 24 do not hinder the connection portion 21 from being put on the end portion of the conductive portion 2.

  Therefore, the insertion portion 26d is inserted into the conductive portion 2 until the front wall 22b of the connection portion main body 22 hits the device support portion 3c by the operation described above. Further, the operation groove 26a of the operation member 26 in the OFF state extends in the longitudinal direction of the connection portion main body 22 as shown in FIG.

  Next, the operating portion 26g is rotated 90 degrees so that the operating groove 26a extends in the width direction of the connecting portion main body 22 while extending the operating portion 26g against the return coil spring 44, whereby the operating member 26 is moved to the first position. It arrange | positions to the 2nd position shown in FIG.

  In this case, since the operation part 26g and the insertion part 26d are connected by the uneven | corrugated fitting part with the connection hole 26h connection convex part 26f, it rotates integrally. Since the engaging portion 26b of the operation member 26 hits the standing wall surface of the holding portion 43 of the rotation angle restricting portion 22e of the connection portion main body 22, the rotation of the operation member 26 is restricted to 90 degrees. Is appropriately rotated and is reliably disposed at the second position.

  At this stage, the operating portion 26g is pushed down by the coil spring 41 as shown in FIG. 21, so that the engaging portion 26b is fitted into the holding portion 43 as shown in FIG. Due to the engagement of the engagement portion 26b with the holding portion 43, the operation member 26 having the operation portion 26g and the insertion portion 26d is held at the second position regardless of the pull back force of the return coil spring 44.

  With this arrangement, as shown in FIG. 21, an engagement state is formed in which the engagement convex portion 16e of the operation member 26 enters the gap G of the conductive portion main body 3 and is hooked on the device support portion 3c from above. The part 21 is mechanically connected to the end of the conductive part 2.

  At the same time, the cam portion 26c of the insertion portion 26d rotated 90 degrees as described above separates the opposite end portions 24a of the pair of contact fittings 24 while elastically deforming each other as shown in FIG. Push in the direction. Therefore, the distance between the contact pieces 24c formed on the end 24a of the contact fitting 24 is wider than the width B of the opening 4 and the mutual interval A between the conductors 6 of the conductive portion 2, and the contact pieces 24c are formed in the conductor 6. The electrical connection state in which the contact piece 24c elastically contacts the conductor 6 is maintained as the contact proceeds. Such a connection state is shown in FIG.

  Thereby, since the conductor 6 of the conductive part 2 and the contact metal fitting 24 of the connection part 21 are electrically connected, the conductors 6 corresponding to the longitudinal direction of the conductive parts 2 that are preceded by a ceiling or the like and are adjacent to each other. Are electrically connected through the connecting portion 21.

  Of the conductive parts 2 arranged in a predetermined shape, the end part of the conductive part 2 whose end part is not covered with the connection part 21 is provided with an end cap made of an insulator that closes the opened end surface ( (Not shown).

  According to the assembly of the conductive device 1 described above, a plurality of conductive portions 2 can be placed in advance in a predetermined shape on a ceiling or the like, and adjacent conductive portions 2 can be mechanically and electrically connected to each other by the connection portion 21. . Therefore, even when the conductive portion 2 of the conductive device 1 is laid out in a complicated layout, it is not necessary to assemble the conductive device 1 in the whole or divided state on the ground side and then install it on the ceiling or the like. Thereby, the electroconductive apparatus 1 can be installed on a ceiling etc., without requiring many manual operations for installation. Further, the electrical connection around the connecting portion 21 is also preferable in that a wire connection is not required.

  Further, as is apparent from the description of the assembly described above, in a state where the operation member 26 is disposed at the first position, the pair of contact fittings 24 and the insertion portion 26d of the connection portion 21 are connected to the pair of conductors 6. It is in a state narrower than the mutual distance A and the width B of the opening 4. Therefore, when the contact fitting 24 and the insertion portion 26d attached to the connection portion main body 22 are inserted into the end portion of the conductive portion 2 through the opening 4, the contact fitting 24 and the insertion portion 26d are insulated from each other. 7 and the conductor 6 can be prevented from being inserted into the conductive portion 2 by force.

  As a result, as the operating member 26 is inserted and rotated to the second position, a part of the insulating material 7 is peeled off, and the contact piece 24 c formed on the conductor 6 and the end 24 a of the contact fitting 24. There is no possibility that the contact fitting 24 is excessively elastically deformed and its springiness is not lowered. Therefore, the reliability of the electrical connection between the conductor 6 and the contact fitting 24 is increased, in other words, the reliability of the electrical connection between the conductive portion 2 and the connection portion 21 can be improved.

  In addition, the connection portion main body 22 included in the connection portion 21 of the conductive device 1 having the above configuration covers the outer surface of the end portion of the conductive portion 2 that is disposed adjacently. Therefore, the installation accuracy of the conductive part 2 relative to the installation location such as the ceiling is rough, and even if there is a gap between the opposite ends of the conductive part 2, it is covered with the connection part main body 22 and the appearance is lowered. You can avoid it. In addition, because of this, high accuracy is not required for the installation of the conductive portion 2, so that the installation workability of the conductive portion 2 at the installation location can be improved.

  In the assembly described above, when the rotation operation of the operation member 26 is halfway and the engagement portion 26b is not engaged with the holding portion 43 in the second position, the spring force of the return coil spring 44 is applied to the operation portion 26g. Therefore, the operation member 26 is pulled back to the first position. Therefore, by confirming the direction of the linear operation groove 26a formed on the lower surface of the operation member 26 by visual or tactile sense, it is possible for the construction worker to know the quality of the connection state.

  In addition, as described above, the engaging portion 26 b is fitted into the holding portion 43, and at the same time, the operation portion 26 g is pushed down according to the depth of the holding portion 43 by the force of the coil spring 41. Thereby, as shown in FIG. 21, the operation part 26g is arrange | positioned in the height position from which the lower surface and the lower surface of the connection part main body 22 become substantially flush. The operation member 26 at such a height position is referred to as being in an ON state. The operation groove 26a of the operation member 26 in the ON state extends in the width direction of the connection portion main body 22 as shown in FIG.

  As described above, the height of the operation unit 26g is changed from the above-described OFF state to the ON position, so that the construction worker can know that an appropriate connection has been made. At the same time, even if the operating member 26 is forgotten to be rotated from the first position to the second position, the height position of the lower surface of the operating portion 26g is confirmed in the subsequent inspection, so that the operating member 26 is forgotten to rotate. I can understand that.

  Further, the engaging portion 26b is provided so as to protrude in the direction in which the cam portion 26c extends, and the operating member 26 is disposed at the second position, and the operating portion 26b is engaged with the holding portion 43. A holding portion 43 is provided on an extended line in a direction in which the linear operation groove 26a opened on the lower surface of 26g extends. Therefore, as described above, the operation portion 26g is rotated so that the operation groove 26a extends in the width direction of the connection portion main body 22, and the operation member 26 is disposed at the second position to engage the engagement portion. In order to determine that 26b is engaged with the holding portion 43, the direction of the operation groove 26a with respect to the connection portion main body 22 can be determined as a guide.

  A sixth embodiment of the present invention will be described with reference to FIG. In the following description, the same components as those in the fifth embodiment are denoted by the same reference numerals and description thereof is omitted. In the sixth embodiment, the operation member is integrally formed without being divided into an upper part and a lower part, and the operation member is arranged from the first position to the second position by the rotation operation. The point from which the whole member accompanied the up-and-down movement differs from 5th Embodiment.

  Therefore, in the sixth embodiment, the engagement convex portion 26e is formed thinner than the gap G so that the entire operation member 26 can be vertically moved.

  At the same time, in order to prevent the contact piece 24c of the contact fitting 24 from interfering with the insulating material 7 along with the vertical movement of the entire operation member 26, a conductor having a wide width is adopted as the operation member 26. The contact piece 24c can be brought into contact with the conductor 6 regardless of whether it is arranged at a low position or at a high position.

  Further, the operation member 26 is formed with a linear operation groove 26a opened on the lower surface thereof.
