Description

[Technical Field]

[0001] The present disclosure relates to a plug for a wiring duct. [Background technology]

[0002] Electrical appliances are sometimes installed on ceiling surfaces. Spotlights, for example, are well-known examples of such electrical appliances. These electrical appliances are sometimes attached to wiring ducts. A wiring duct is a tubular member installed on a ceiling surface. Electrical wires are arranged inside the wiring duct. Wiring ducts make it possible to organize a large number of electrical wires. Furthermore, wiring ducts make it easy to attach and detach spotlights, for example. This allows for flexible changes to the lighting layout, etc.

[0003] An electrical appliance to be attached to a wiring duct has a wiring duct plug to be attached to the wiring duct. For example, the wiring duct plug disclosed in Patent Document 1 has a first engagement part that rotates to engage with the wiring duct and a second engagement part that rotates in conjunction with the first engagement part to engage with the wiring duct. The first engagement part has an electrical connection part that contacts the conductor of the wiring duct and a first operating part. The second engagement part has a second operating part.

[0004] In the above-mentioned wiring duct plug, the wiring duct plug can be engaged only by operating the second operating part. Furthermore, the wiring duct plug can be released only by operating the first operating part. This prevents the plug from being engaged only by the first engaging part. As a result, the load of the electrical appliance is not applied only to the electrical connection part and the first engaging part. This prevents excessive load from being applied to the electrical connection part. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-192289 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the wiring duct plug disclosed in Patent Document 1, the first operating portion and the second operating portion are adjacent to each other with no gap between them in the engaged state or the disengaged state. Such a wiring duct plug requires small dimensional tolerances during manufacturing, which can increase manufacturing costs. Furthermore, such a wiring duct plug requires strict dimensional control during manufacturing, which can increase manufacturing man-hours.

[0007] Therefore, an object of the present disclosure is to provide a plug for a wiring duct that can realize a configuration in which there is no engagement state with only an engagement portion having an electrical connection portion, with a simple configuration. [Means for solving the problem]

[0008] The wiring duct plug of the present disclosure is a wiring duct plug that is provided in an electrical appliance and attached to a wiring duct, and comprises: a first rotating body having a first engagement portion that rotates to engage with the wiring duct, a first rotating portion that rotates together with the first engagement portion, and an electrical connection portion that contacts the conductor of the wiring duct; and a second rotating body having a second engagement portion that rotates to engage with the wiring duct and a second rotating portion that rotates together with the second engagement portion, wherein a first protrusion portion is formed on the first rotating portion and a second protrusion portion is formed on the second rotating portion, and when the first engagement portion and the second engagement portion are not engaged with the wiring duct and the first engagement portion is rotated to engage with the wiring duct, the first protrusion portion is engaged by the second protrusion portion. [Effects of the Invention]

[0009] According to the wiring duct plug of the present disclosure, a configuration in which there is no state of engagement with only the engaging portion having the electrical connection portion can be realized with a simple configuration. [Brief explanation of the drawings]

[0011] An example of an embodiment of the present disclosure will be described in detail below. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating understanding of the present disclosure, and can be appropriately changed according to the application, purpose, specifications, etc.

[0012] [Electrical appliances] A spotlight 100 as an electrical appliance according to an embodiment will be described with reference to FIG.

[0013] The spotlight 100, which is an electrical appliance, is installed on the ceiling surface. More specifically, the spotlight 100 is attached to a wiring duct 110. The wiring duct 110 is arranged on the ceiling surface. The wiring duct 110 will be described in detail later. The spotlight 100 is a lighting appliance that irradiates light at a predetermined point. The spotlight 100 can change the direction or angle of the light. This allows the desired location to be illuminated more brightly. The spotlight 100 can be easily attached to or detached from the wiring duct 110. This allows the lighting layout, etc. to be freely changed.

[0014] It should be noted that the electrical appliance of the present disclosure is not limited to the spotlight 100. The electrical appliance of the present disclosure may be any electrical appliance that can be attached to or detached from the wiring duct 110. For example, the electrical appliance of the present disclosure may be a speaker that is part of an audio system, an air purifier that is part of an air conditioning system, or the like.

[0015] The spotlight 100 as an electrical appliance has a light source 101, a socket (not shown), an appliance body 102, an arm 103, and a wiring duct plug 10, the details of which will be described later. The light source 101 is attached to the socket. The socket is housed in the appliance body 102. The appliance body 102 is rotatably supported by the arm 103. The arm 103 is rotatably supported by the wiring duct plug 10. In other words, the wiring duct plug 10 is one of the components of the spotlight 100.

[0016] In the following description, the direction along the wiring duct 110 may be referred to as the depth direction (X direction in the drawings). Also, the direction perpendicular to the depth direction in the horizontal plane may be referred to as the width direction (Y direction in the drawings). Furthermore, the vertical direction perpendicular to the depth direction and width direction may be referred to as the up-down direction (Z direction in the drawings).

[0017] [Wiring Duct] The wiring duct 110 according to the embodiment will be described with reference to FIG.

[0018] The wiring duct 110 is a tubular member disposed on the ceiling surface. Electric wires (power supply electrodes, which will be described later) are passed through the inside of the wiring duct 110. The wiring duct 110 allows a large number of electric wires to be organized. The spotlight 100 is attached to the wiring duct 110. More specifically, the wiring duct plug 10 of the spotlight 100 is attached to the wiring duct 110.

[0019] The wiring duct 110 is made of, for example, synthetic resin. The wiring duct 110 is formed so as to extend in the depth direction. When viewed in cross section perpendicular to the depth direction, the wiring duct 110 is formed in a substantially C-shape. A duct opening 111 is formed on the lower surface of the wiring duct 110. The duct opening 111 is formed along the depth direction. Flanges 112 are formed inward on both sides of the lower end of the wiring duct 110 in the width direction.

[0020] Two protrusions 113 are formed inside the wiring duct 110. The two protrusions 113 protrude from the middle in the up-down direction of two inner surfaces facing each other in the width direction of the wiring duct 110. A recess 114 is formed at the tip of each protrusion 113. A power supply electrode (not shown) is held inside the recess 114.

[0021] The power supply electrodes are a pair of electrodes that supply AC power to the spotlight 100. A power receiving terminal 35 of the first rotating body 30, which will be described later, is connected to the power supply electrodes. The power supply electrodes are made of a metal such as copper. In the wiring duct 110, grooves 115 are formed between the flange 112 and the protrusion 113, into which a first engagement portion 34 and a second engagement portion 44, which will be described later, are respectively engaged. The shape or size of the wiring duct 110 is not particularly limited.

[0022] [Wiring duct plug] The wiring duct plug 10 will be described with reference to FIGS.

[0023] The wiring duct plug 10 is one component of the spotlight 100. The wiring duct plug 10 is attached to a wiring duct 110. The wiring duct plug 10, as will be described in detail later, can achieve a simple configuration in which there is no engagement state with only the first rotating body 30 having the power receiving terminal 35 as an electrical connection part.

[0024] The wiring duct plug 10 has a main body 20, a first rotating body 30, and a second rotating body 40, each of which will be described in detail later.

[0025] [Main unit] The main body 20 forms the outer shell of the wiring duct plug 10. The main body 20 is formed of, for example, synthetic resin. The main body 20 is hollow. The main body 20 is formed in a substantially cylindrical shape along the up-down direction. More specifically, the main body 20 is formed in a track shape (long hole shape) along the longitudinal direction when viewed in a cross section perpendicular to the up-down direction. Note that the main body of the present disclosure is not limited to a track shape along the longitudinal direction when viewed in a cross section perpendicular to the up-down direction. The main body of the present disclosure may be, for example, rectangular or square when viewed in a cross section perpendicular to the up-down direction.

[0026] A first rotating body 30 and a second rotating body 40 are rotatably supported on the top surface of the main body 20. A wall portion 21 is formed around the periphery of the top surface of the main body 20 except for a portion on one side in the width direction. In the portion of the periphery of the top surface of the main body 20 where the wall portion 21 is not formed, the first operating portion 32 of the first rotating body 30 and the second operating portion 42 of the second rotating body 40 protrude outside the main body 20. The first operating portion 32 and the second operating portion 42 are rotatable in the portion of the periphery of the top surface of the main body 20 where the wall portion 21 is not formed. In other words, the wall portion 21 restricts the rotation of the first operating portion 32 and the second operating portion 42.

[0027] The main body 20 supports the arm 103 so that it can rotate freely around an axis extending in the vertical direction. Inside the main body 20, a power line (not shown) is arranged, which is connected to the power receiving terminal 35 and is connected to a circuit board housed in the fixture main body 102.

[0028] [First body of revolution] The first rotating body 30 rotates and is attached to the wiring duct 110. The first rotating body 30 is electrically connected to the wiring duct 110. The first rotating body 30 is rotatably supported on the upper surface of the main body 20. The first rotating body 30 is disposed on one side in the depth direction of the upper surface of the main body 20. The first rotating body 30, except for the power receiving terminal 35, is formed of, for example, synthetic resin.

[0029] The first rotating body 30 has a first rotating portion 31, a first operating portion 32, a first engaging portion 34, a power receiving terminal 35 as an electrical connection portion, and a first protrusion portion 36, each of which will be described in detail below.

[0030] Hereinafter, the state in which the wiring duct plug 10 is attached to the wiring duct 110 may be described as an "engaged state." In the "engaged state," the first rotating body 30 and the second rotating body 40 are engaged with the wiring duct 110. More specifically, in the "engaged state," the first engaging portion 34 and the second engaging portion 44 are engaged with the groove portion 115 of the wiring duct 110. Also, in the "engaged state," the power receiving terminal 35 is engaged with the recessed portion 114 of the wiring duct 110.

[0031] Additionally, the position at which the first rotating body 30 or the second rotating body 40 engages with the wiring duct 110 may be referred to as the "engagement position." Furthermore, the rotational direction in which the first rotating body 30 or the second rotating body 40 attempts to engage with the wiring duct 110 may be referred to as the "engagement direction."

[0032] Hereinafter, the state in which the wiring duct plug 10 is removed from the wiring duct 110 may be described as the "released state." In the "released state," the first rotating body 30 and the second rotating body 40 are released from engagement with the wiring duct 110. More specifically, in the "released state," the first engaging portion 34 and the second engaging portion 44 are released from engagement with the groove portion 115 of the wiring duct 110. Also, in the "released state," the power receiving terminal 35 is released from engagement with the recessed portion 114 of the wiring duct 110.

[0033] In addition, the position where the first rotating body 30 or the second rotating body 40 is released from the wiring duct 110 may be described as the "release position." Furthermore, the rotation direction in which the first rotating body 30 or the second rotating body 40 attempts to be released from the wiring duct 110 may be described as the "release direction."

[0034] The first rotating part 31 is a base part of the first rotating body 30. The first rotating part 31 is formed in a substantially disk shape. The first rotating part 31 is arranged on one side in the depth direction of the top surface of the main body 20. The first rotating part 31 is also arranged close to the second rotating part 41. A first operating part 32 is formed on one side in the width direction of the first rotating part 31.

[0035] The first operating part 32 is a part that is rotated. The first operating part 32 is formed in a strip shape. The first operating part 32 is formed on one side in the width direction of the first rotating part 31. The first operating part 32 also protrudes from one side in the width direction. When the first operating part 32 rotates in the release direction, the first operating part 32 is locked by the wall part 21 of the main body 20. In other words, when the first rotating body 30 is in the release position, the first operating part 32 is locked by the wall part 21 of the main body 20.

[0036] The first engagement portion 34 is a portion that engages with the groove portion 115 of the wiring duct 110. The first engagement portion 34 is formed in a strip shape. The first engagement portion 34 is provided above the first rotating portion 31. The first engagement portion 34 rotates together with the first rotating portion 31. When the first rotating body 30 is in an engaged state, the longitudinal direction of the first engagement portion 34 is parallel to the width direction. On the other hand, when the first rotating body 30 is in a released state, the longitudinal direction of the first engagement portion 34 is parallel to the depth direction.

[0037] The power receiving terminal 35, which serves as an electrical connection part, is electrically connected to the power feeding electrode of the wiring duct 110 when the first rotating body 30 is in the engaged state. The power receiving terminal 35 is provided above the first engagement part 34. The power receiving terminal 35 rotates together with the first engagement part 34 and the first rotating part 31. When the first rotating body 30 is in the engaged state, the longitudinal direction of the power receiving terminal 35 is parallel to the width direction. On the other hand, when the first rotating body 30 is in the released state, the longitudinal direction of the power receiving terminal 35 is parallel to the depth direction.

[0038] The first protrusion 36 is a part of the disk-shaped first rotating part 31 formed as a corner.

[0039] When the first rotating body 30 and the second rotating body 40 are in a disengaged state and the first rotating body 30 is rotated in the engagement direction, the first protrusion 36 is locked by the second protrusion 46 of the second rotating body 40. In other words, when the first rotating body 30 and the second rotating body 40 are in a disengaged state, the rotation of the first rotating body 30 in the engagement direction is restricted by the second protrusion 46. As a result, when rotating the first rotating body 30 and the second rotating body 40 in the engagement direction, the second rotating body 40 must be rotated first. This prevents only the first rotating body 30 from entering the engaged state. As a result, the load of the spotlight 100 acting only on the power receiving terminal 35 and the first engagement portion 34 can be reduced. This prevents excessive load from acting on the power receiving terminal 35.

[0040] The wiring duct plug 10 of this embodiment has a simple configuration in which the first protrusion 36 is formed on the disk-shaped first rotating part 31 and the second protrusion 46 is formed on the disk-shaped second rotating part 41. This simple configuration makes it possible to prevent only the first rotating body 30 from being in an engaged state.

[0041] [Second body of revolution] The second rotating body 40 rotates and is attached to the wiring duct 110. The second rotating body 40 is rotatably supported on the upper surface of the main body 20. The second rotating body 40 is disposed on the other side in the depth direction of the upper surface of the main body 20. The second rotating body 40 is formed from, for example, synthetic resin.

[0042] The second rotating body 40 has a second rotating portion 41, a second operating portion 42, a second engaging portion 44, and a second protruding portion 46, each of which will be described in detail later.

[0043] The second rotating part 41 is a base part of the second rotating body 40. The second rotating part 41 is formed in a substantially disk shape. The second rotating part 41 is arranged on the other side in the depth direction of the top surface of the main body 20. The second rotating part 41 is also arranged close to the first rotating part 31. A second operating part 42 is formed on one side in the width direction of the second rotating part 41.

[0044] The second operating part 42 is a part that is rotated. The second operating part 42 is formed in a strip shape. The second operating part 42 is formed on one side in the width direction of the second rotating part 41. The second operating part 42 also protrudes from one side in the width direction. When the second operating part 42 rotates in the engagement direction, the second operating part 42 is locked by the wall part 21 of the main body 20. In other words, when the second rotating body 40 is in the release position, the second operating part 42 is locked by the wall part 21 of the main body 20.

[0045] The second engagement portion 44 is a portion that engages with the groove portion 115 of the wiring duct 110. The second engagement portion 44 is formed in a strip shape. The second engagement portion 44 is provided above the second rotating portion 41. The second engagement portion 44 rotates together with the second rotating portion 41. When the second rotating body 40 is in an engaged state, the longitudinal direction of the second engagement portion 44 is parallel to the width direction. On the other hand, when the second rotating body 40 is in a released state, the longitudinal direction of the second engagement portion 44 is parallel to the depth direction.

[0046] The second protrusion 46 is a portion formed so as to be wider from the base end side to the middle part of the second operating portion 42.

[0047] When the first rotating body 30 and the second rotating body 40 are in a disengaged state and the first rotating body 30 is rotated in the engagement direction, the second protrusion 46 locks the first protrusion 36 of the first rotating body 30. In other words, when the first rotating body 30 and the second rotating body 40 are in a disengaged state, the rotation of the first rotating body 30 in the engagement direction is restricted by the second protrusion 46. As a result, when rotating the first rotating body 30 and the second rotating body 40 in the engagement direction, the second rotating body 40 must be rotated first. This prevents only the first rotating body 30 from entering the engaged state. As a result, the load of the spotlight 100 does not act only on the power receiving terminal 35 and the first engagement portion 34. This prevents an excessive load from acting on the power receiving terminal 35.

[0048] Furthermore, when the first rotating body 30 and the second rotating body 40 are engaged and the first rotating body 30 is rotated in the disengagement direction, the second protrusion 46 engages with the first operating portion 32 of the first rotating body 30. In other words, when the first rotating body 30 and the second rotating body 40 are engaged, the rotation of the second rotating body 40 in the disengagement direction is restricted by the first operating portion 32. As a result, when the first rotating body 30 and the second rotating body 40 are rotated in the disengagement direction, the first rotating body 30 must rotate first. This prevents only the first rotating body 30 from entering the engaged state. As a result, the load of the spotlight 100 does not act only on the power receiving terminal 35 and the first engaging portion 34. This prevents an excessive load from acting on the power receiving terminal 35.

[0049] The wiring duct plug 10 of this embodiment has a simple configuration in which the first protrusion 36 is formed on the disk-shaped first rotating part 31 and the second protrusion 46 is formed on the disk-shaped second rotating part 41. This simple configuration makes it possible to prevent only the first rotating body 30 from being in an engaged state.

[0050] [Released state] The released state of the wiring duct plug 10 will be described with reference to FIG.

[0051] In the released state of the wiring duct plug 10, the longitudinal direction of the first engagement portion 34 of the first rotating body 30 and the longitudinal direction of the second engagement portion 44 of the second rotating body 40 are parallel to the depth direction. Here, the groove portion 115 of the wiring duct 110 is parallel to the depth direction. Therefore, the first engagement portion 34 and the second engagement portion 44 are disengaged from the groove portion 115.

[0052] Furthermore, when the wiring duct plug 10 is in the released state, the longitudinal direction of the power receiving terminal 35 of the first rotating body 30 is the depth direction. Here, the recess 114 of the wiring duct 120 is parallel to the depth direction. Therefore, the power receiving terminal 35 is removed from the recess 114. Furthermore, the first operating part 32 is inclined, for example, at approximately 45 degrees from the width direction to one side in the depth direction. The second operating part 42 is inclined, for example, at approximately 45 degrees from the width direction to one side in the depth direction.

[0053] [Engaged state] The engaged state of the wiring duct plug 10 will be described with reference to FIG.

[0054] When the wiring duct plug 10 is in the engaged state, the longitudinal direction of the first engagement portion 34 of the first rotating body 30 and the longitudinal direction of the second engagement portion 44 of the second rotating body 40 are parallel to the width direction. As a result, the first engagement portion 34 and the second engagement portion 44 engage with the groove portion 115 of the wiring duct 110.

[0055] Furthermore, when the wiring duct plug 10 is in the engaged state, the longitudinal direction of the power receiving terminal 35 of the first rotating body 30 is parallel to the width direction. As a result, the power receiving terminal 35 engages with the recess 114 of the wiring duct 110. Furthermore, the first operating part 32 is inclined, for example, at approximately 45 degrees from the width direction to the other side in the depth direction. The second operating part 42 is inclined, for example, at approximately 45 degrees from the width direction to the other side in the depth direction.

[0056] [Installation operation] The operation of attaching the wiring duct plug 10 will be described with reference to FIG.

[0057] When attaching the wiring duct plug 10 to the wiring duct 110, the first rotating body 30 and the second rotating body 40 are rotated in the engagement direction (in the direction of the arrow in the figure) so that the wiring duct plug 10 changes from a disengaged state to an engaged state. At this time, for example, if only the first rotating body 30 is rotated in the engagement direction, the first protrusion 36 of the first rotating body 30 is engaged with the second protrusion 46 of the second rotating body 40. As a result, when rotating the first rotating body 30 and the second rotating body 40 in the engagement direction, the second rotating body 40 must be rotated first. This prevents only the first rotating body 30 from entering the engaged state. As a result, the weight of the spotlight 100 is not applied only to the power receiving terminal 35 and the first engagement portion 34. This prevents excessive load from being applied to the power receiving terminal 35.

[0058] [Removal action] The operation of removing the wiring duct plug 10 will be described with reference to FIG. When removing the wiring duct plug 10 from the wiring duct 110, the first rotating body 30 and the second rotating body 40 are rotated in the disengagement direction (the direction of the arrow in the figure) so that the wiring duct plug 10 changes from an engaged state to a disengaged state. At this time, for example, if only the second rotating body 40 is rotated in the disengagement direction, the second operating portion 42 of the second rotating body 40 engages with the first protrusion 36 of the first rotating body 30. As a result, when rotating the first rotating body 30 and the second rotating body 40 in the disengagement direction, the first rotating body 30 must be rotated first. This prevents only the first rotating body 30 from entering the engaged state. As a result, the load of the spotlight 100 is not applied only to the power receiving terminal 35 and the first engagement portion 34. This prevents excessive load from being applied to the power receiving terminal 35. [summary] The present disclosure is further illustrated by the following embodiments.
