The insertion guide projection 31d is a plate-like projection that protrudes outward from the side wall facing surface 31k and extends in the longitudinal direction (see FIG. 5C).

  The insertion base 31a has the one side locking projection 31b on the side close to the exposed surface 31j of the side wall facing surface 31k. On the other hand, the retaining projection 31b is a plate-like projection that protrudes outward from the side wall facing surface 31k and extends in the longitudinal direction. On the other hand, when mounted on the duct rail 100, the retaining projection 31b abuts on the inner side surface of the guide 102a.

Most of the remaining part of the exposed surface 41j is covered with the exposed part 32 of the first member 3 when the first member 3 and the second member 4 are united (FIG. 3 (B), FIG. 5 (A) reference).

  The insertion base 41a has an insertion guide protrusion 41d on the side closer to the ceiling attachment wall opposite surface 41f of the side wall opposite surface 41k. The insertion guide projection 41d is a plate-like projection that protrudes outward from the side wall facing surface 41k and extends in the longitudinal direction (see FIG. 5C).

  The insertion base 41a has the other retaining projection 41b on the side closer to the exposed surface 41j of the side wall facing surface 41k. On the other hand, the retaining projection 41b is a plate-like projection that protrudes outward from the side wall facing surface 41k and extends in the longitudinal direction. On the other hand, when mounted on the duct rail 100, the retaining projection 41b abuts on the inner side surface of the guide 102b.

  In the insertion base 41a, a contact storage groove 41c is formed in parallel to the region sandwiched between the insertion guide projection 41d on the side wall opposing surface 41k and the other prevention projection 41b. A part of the contactor 45 is stored in the contactor storage groove 41c.

  On the other hand, the surface of the retaining projection 41 b in contact with the guide 102 of the duct rail 100 is formed on a horizontal surface parallel to the guide 102. Further, the back surface 41e is formed at a right angle with respect to the other retaining projection 41b. That is, the back surface 41 e is formed in a plane (a plane in which the normal direction is the width direction of the duct rail 100) extending in the longitudinal direction and the height direction of the duct rail 100.

In this embodiment, the sum of the distance W31a and the distance W41a is formed to be substantially the same as the width W104. Thus, when the first member 3 and the second member 4 are brought into contact with each other to be integrated, the plug portion 10 constituted by the first member 3 and the second member 4 can easily slide in the sliding direction by its own weight or the like. It is attached to the duct rail 100 with such a degree of stability that it can not slide and slide when a person tries to slide with a strong force.

  In addition, the difference between the distance W31b of the first member 3 and the distance W31a can be made shorter than or equal to the projection length on the inner surface side of the guide 102 (the length in the width direction of the guide 102), And, it can be half or more, preferably two thirds or more, of the protruding length on the inner surface side of the guide 102.

The side wall facing surface 31k is brought close to the side wall 101a of the duct rail 100 until the side wall facing surface 31k of 31a abuts on the tip of the guide 102a of the duct rail 100. At this time, the contact terminal portion 35d of the first member 3 is pressed against and brought into contact with the conductor line 103 of the duct rail 100 by the elastic force of the plate spring portion 35c, so that a conductive state can be established.

  Preferably, the insertion of the first member 3 is performed in a state where the AC / DC conversion unit 5 is fixed to the AC / DC conversion installation unit 33 of the first member 3. As a result, it is possible to reduce labor and time for fixing the AC / DC conversion unit 5 to the first member 3 by screwing or the like toward the ceiling.

It is preferable to use the same length, more preferably the same length or more, and it is preferable to set the length twice or more.
Further, on both rear surfaces 31 e and 41 e (contact surfaces), unevenness (horizontal stripe pattern) having a low height of a plurality of filaments extending in parallel to the longitudinal direction of the duct rail 100 may be formed. As a result, in the state in which both the back surfaces 31e and 41e are in contact with each other, they slide easily in the length direction of the contact surface, but they do not easily slide in the height direction of the contact surface. For this reason, even if large shear stress is applied in the height direction between both the back surfaces 31e and 41e due to the own weight of the power supply unit 1 etc. for hanging duct rails, both the back surfaces 31e and 41e do not slip easily in the height direction. And can abut.

<DC light emitting unit mounting plug>
FIG. 8 (A) is a perspective view of the DC light emitting unit mounting plug 220, FIG. 8 (B) is a perspective view of the DC light emitting unit mounting plug 220 with the front and back reversed, and FIG. FIG. 9B is a vertical cross-sectional view of a state in which the light emitting unit mounting plug 220 is inserted for mounting on the duct rail 100. FIG. 9B is a state where the DC light emitting unit mounting plug 220 inserted in the duct rail 100 is rotated 90 degrees and mounted. It is a partial longitudinal cross-sectional view of.

  The DC light emitting unit mounting plug 220 has a plate-like main portion 242 (see FIG. 8A) having a thickness that is substantially rectangular and a side of the duct rail 100 (FIG. 8A) from the main portion 242 (exposed portion). (The upper side in FIG. 1) and a locking member 221 (insertion portion) provided on the duct rail 100 side of the rotary locking member 230.

  The main body portion 242 is provided with a through hole 243 in the vertical direction (thickness direction) at the center of a rectangular plate, and four screw holes 245 are respectively provided on four floor surface sides (opposite to the duct rail 100). It is provided. A recess 247 is provided on the surface of the main body 242 opposite to the duct rail 100. The recess 247 has a constant width at the center of the short side recessed to a short distance to a position just before the through hole 243. Near the center of the surface on the duct rail 100 side of the main body portion 242, a spacer portion 241 which is convex in a substantially ring shape is provided. The spacer portion 241 is formed at the same height as a projecting piece 102s (see FIG. 9B) which is straight in the longitudinal direction formed by the one side wall 101a of the duct rail 100 projecting from the guide 102.

  As shown in FIG. 8A, the rotation locking body 230 has a shape in which a part of the disk part 231 protrudes in the radial direction as a rectangular plate-like part 234, and the penetration of the main body 242 to the center of the disk part 231. Through holes 235 (see FIG. 9A) communicating with the holes 243 are provided in the thickness direction.

  As shown in FIG. 8A, the plate-like portion 234 protrudes in the same width as the opening 104 of the duct rail 100 on the duct rail 100 side (upper side in FIG. 8A) slightly inside the outer end. Engaging claws 232 are provided. Further, the outer end portion of the plate-like portion 234 is formed thinner than the height of the engagement claw 232, and the operation piece 233 is formed.

  The rotation locking body 230 is disposed such that the plate-like portion 234 extends toward one side in the longitudinal direction of the main body portion 242, and the distance from the tip of the plate-like portion 234 (tip of the operation piece 233) to the through hole 235 is The end of the operation piece 233 and the end of the main body 242 are flush with each other. The end of the operation piece 233 and the end of the main body 242 are flush with each other. Further, the width in the short direction of the plate-like portion 234 and the width of the engagement claw 232 are configured to be slightly the same width as the opening 104 of the duct rail 100 and slightly shorter. For this reason, the engaging claws 232 and the plate-like portion 234 are accommodated in the opening 104 at the time of mounting, and their end portions abut on the edge on the opening 104 side of the guide 102 (see FIG. 9B) .

  The rotation locking body 230 is integrally formed of a material, such as acrylic or resin, which is bent when pressed with an unnecessary finger or the like but has an elastic force that returns to the original level when the pressing is released.

  The anti-slip member 221 has a rectangular short side formed in an arc shape whose center is convex, and is configured such that the longitudinal direction is parallel to the short direction of the main body portion 242. The width in the short direction of the locking member 221 is formed slightly shorter than the width of the opening 104 of the guide rail 100, and the length in the longitudinal direction of the locking member 221 is the horizontal protrusion of the guide 102 of the guide rail 100. It is formed shorter than the width and long enough to be engaged with the guide 102 to prevent it from coming off. The longitudinal projecting portion functions as a retaining projection 222. The arc-shaped short side of the stopper body 221 is formed in an arc shape along the circumference when a true circle is drawn from the center, and is formed slightly convex toward the main body portion 242, and this convex portion Function as locking projections 223.

  The anti-slip member 221 has, at its center, a through hole 225 (see FIG. 9A) communicating with the through hole 243 of the main body 242 and the through hole 235 of the rotation locking body 230. Further, the retaining member 221 is provided with a spacer portion 224 in which the periphery of the through hole 225 is convex in a disk shape toward the duct rail 100 side and has a diameter substantially the same as the width of the opening 104. The height of the spacer portion 224 is formed slightly higher than the height of the guide 102 (see FIG. 9B) of the duct rail 100.

<Mounting of DC light emitting unit mounting plug on duct rail>
First, as shown in FIG. 9A, the longitudinal direction of the retaining member 221 is aligned in the longitudinal direction of the duct rail 100, and the retaining member 221 is inserted into the opening 104 of the duct rail 100 to the back. At this time, the plate-like portion 234 of the rotation locking member 230 protrudes in the width direction of the duct rail 100. At this time, the spacer portion 224 is positioned between the two guides 102 of the duct rail 100.

  At this time, as shown in FIG. 7A, the suspending arm 207 is lightly held by a screw 213 so that the DC light emitting unit mounting plug 220 and the suspending arm 207 can be relatively rotated. Keep it.

  Next, as shown in FIG. 9B, the DC light emitting unit mounting plug 220 is rotated 90 degrees in the horizontal direction. At the time of rotation, the engagement claws 232 of the rotation locking member 230 may contact the duct rail 100 to prevent the rotation. In this case, the operation piece 233 is pressed toward the main body portion 242 to retract the engagement claw 232 into the recess 247 (see FIG. 8B), thereby releasing the engagement claw 232 from being caught. Then, the elastic force of the rotation locking member 230 allows the engagement pawl 232 without being caught by the subsequent rotation, and rotates until the engaging claw 232 fits into the opening 104 (until it rotates by 90 degrees).

  When rotated 90 degrees, the engaging claws 232 fit into the openings 104 by the elastic return force, the inner pieces of the two guides 102 and the engaging claws 232 contact, and the DC light emitting unit mounting plug 220 against the duct rail 100 Relative rotation is prevented.

  At this time, the locking member 221 rotates while the locking convex portion 223 is in contact with the inner side surface of the guide 102, and the locking protrusion 222 having the locking convex portion 223 and the guide 102 face each other in parallel. In this state, the DC light emitting unit mounting plug 220 is prevented from coming off the duct plug 100.

  Thus, when the DC light emitting unit mounting plug 220 is rotated 90 degrees, the screw 213 is loosened to such an extent that the hanging arm 207 (see FIG. 7A) mounted on the DC light emitting unit mounting plug 220 can rotate. Therefore, even if a plurality of hanging arms 207 are provided as shown in FIG. 1A and can not rotate, the DC light emitting unit mounting plug 220 can be rotated 90 degrees.

  Thereafter, the DC light emitting unit mounting plug 220 and the suspending arm 207 are fixed by firmly turning the screw 213, and the DC coming out of the through holes 225, 235, 243 (see FIG. 9A) of the DC light emitting unit mounting plug 220. Electrically connect power supply lines 215a and 215b (conductor lines, see FIG. 1A) to DC lines La, Lb or DC output portions TO1, TO2 (see FIG. 2A) of duct rail power supply unit 1. .

In this manner, it is possible to provide the beautifully beautiful duct rail DC light emission system 201 in which the power supply lines and the like do not extend around the duct rail 100.
A cover (not shown) is attached to a portion of the opening 104 of the duct rail 100 where the DC power supply lines 215a and 215b and the DC lines La and Lb can be seen, providing a beautiful beauty in which the power supply line etc. can not be completely seen. it can.

  With the above configuration, there is no need to undergo PSE compatibility inspection even if the shape, design, etc. of the light emitting apparatus is changed, and the DC light emission system 1 for duct rail that is easy to mount on the duct rail and is suitable is provided. it can.

  The DC power supply lines 215a and 215b for supplying DC power to the DC light emitting unit 202 pass through the inside of the hanging arm 207, pass through the through holes 225, 235 and 243 of the DC light emitting unit mounting plug 220, and Being disposed within the hollow interior 105 (see FIG. 2B), it is possible to make the DC power supply lines 215a, 215b invisible at all.

  In addition, since the longitudinal direction of the locking member 221 and the longitudinal direction of the rotary locking member 230 are arranged in a direction different by 90 degrees, the DC light emitting unit mounting plug 220 is rotated 90 degrees in the horizontal direction. By operation, the retaining member 221 prevents retention from the duct rail 100 (supports the weight of the DC light emitting unit 202 to prevent removal) and rotation locking of the DC light emitting unit mounting plug 220 (DC due to earthquake or vibration) Both of the light emitting unit mounting plug 220 can be prevented from rotating.

  In addition, since the DC light emitting unit mounting plug 220 does not contact the conductor line 103 of the duct rail 100 and does not perform energization to AC power, the DC light emitting unit mounting plug 220 shown in FIG. If the DC power supply lines 215a and 215b can be inserted and used as shown in FIG. 1A, the DC power supply lines 215a and 215b etc. are not inserted as shown on the right side of the DC light emitting unit mounting plug 220. It can also be used for physical fixing to the duct rail 100 at the time of suspension.

  In addition, the rotation locking member 230 can prevent rotation after mounting, and when it is desired to remove it, the operation piece 233 is operated to retract the plate-like portion 234 into the recess 247 to rotate the DC light emitting unit mounting plug 220 It can be easily removed.

  Further, the spacer portion 241 is provided in the main body portion 242, so that the DC light emitting unit mounting plug 220 can be rotated when the DC light emitting unit mounting plug 220 is attached to and removed from the duct rail 100 The engaging claws 232 of the body 230 can get over the projecting pieces 102s (see FIG. 9B) of the duct rail 100.

  In addition, it is possible to provide the power supply unit 1 for the duct rail that does not use the turning operation of the operation lever at the time of attaching and detaching to the duct rail 100.

  The plug portion 10 of the duct rail power supply unit 1 includes a first member 3 engaged and energized in one of the width directions of the duct rail 100 and a second member 4 engaged and energized in the other in the width direction of the duct rail 100. It consists of For this reason, the plug portion 10 inserts the insertion portions 31 and 41 into the hollow interior 105 at different positions in the longitudinal direction of the duct rail 100 for the first member 3 and the second member 4 respectively, and slides one or both of them. By bringing the back surfaces 31 e and 41 e into contact at the same position in the longitudinal direction, engagement and energization to the duct rail 100 can be easily realized.

  The mounting operation of the duct rail power supply unit 1 is performed by inserting the first member 3 through the opening 104, inserting the second member 4 through the opening 104, sliding them, positioning them in the width direction and abutting each other. Only by doing, it can be arranged stably. After that, the connection of the arrangement and the attachment of the unit case 2 are sufficient, so it is possible to prevent the arm from being extended upward and performing a complicated attachment operation while facing upward on the stepladder etc. It can be worn easily.

The present invention is not limited to the above-described embodiment, but can be various embodiments.
For example, in FIG. 3C, the first member 3 is longer in the longitudinal direction of the duct rail 100 in the upper and lower direction than the center in the vertical direction (longitudinal direction of the duct rail 100) in FIG. A third member of the same shape as the upper portion of the second member 4 but with the contact 45 removed (the length of the second member 4 is approximately twice as long as that of the second member 4). Not shown) may be used. In this case, the first member 3 and the second member 4 are fixed at a position where the exposed portions 32 and 42 abut, and a third member is abutted and fixed near the upper end of the first member 3 in the figure. Can. As a result, the first member 3 can be formed long for stable installation, and the second member 4 and the third member can be stably installed by sliding them from both ends in the longitudinal direction. At this time, if the first member 3 and the second member 4 are simply formed long, the sliding distance is long and the contact surface is also wide, and it becomes difficult to slide in the middle by the frictional force in the middle, but such a thing is prevented and it is simple Can be stably attached to the duct rail 100.

  In addition, the thickness of the insertion portion 41 (see FIG. 3B) of the second member 4 in the width direction is tapered at the leading portion (upper right portion in FIG. 3B) to be slid for mounting. A chamfered portion and a tapered portion may be provided on the back surface. The chamfered portion may be provided on the back surface 41e (see FIG. 5C), and the tapered portion may be provided on the side wall opposing surface 41k (see FIG. 5C). good. The tapered portion may be tapered in a longer distance than the chamfered portion. When configured in this manner, the chamfered portion can slide the first member 3 and the second member 4 relative to each other to prevent sticking at the beginning of overlapping, and the movement when sliding from there is a tapered portion Can be smoother.

  Further, the AC / DC conversion unit 5 may be configured to be mounted on the duct rail 100 suspended from the ceiling. In this case, an AC / DC converting portion extending from the opening 104 of the duct rail 100 through the periphery of the duct rail 100 extends a wire for energization from the contacts 35 and 45 of the first member 3 and the second member 4 respectively. It may be connected to each of the AC input sections TI1 and TI2 of 5. Also in this case, the first member 3 and the second member 4 are firmly fixed to the duct rail 100 and can be stably energized to convert AC power into DC power.

  If the DC light emitting unit 202 is small or lightweight, it is preferable that the DC light emitting unit 202 be attached to the duct rail 100 by one hanging arm 207 and one DC light emitting unit mounting plug 220. Also in this case, it is possible to provide a DC light emission system 201 for a duct rail that is beautiful in appearance.

  Further, the duct rail power supply unit 1 may be physically fixed to the duct rail 100 and electrically connected to the conductor line 103 by a structure different from that of the plug portion 10 described above. Also in this case, it is possible to provide a DC light emission system 201 for a duct rail for beautiful beauty.

  The present invention can be used in the industry of electrically connecting and fixing a device driven by DC power to a duct rail through which AC power flows.
