A state in which the terminal block 81 and the like are viewed from a direction orthogonal to the vertical direction is a side view. A state in which the sectional shape of the terminal block 81 and the like is viewed is referred to as a sectional view.

  The terminal block 81 of the present embodiment is a small and vertically long terminal block. The terminal block 81 includes a quick connection terminal portion, a terminal housing 83, and a cover 85. The quick connection terminal portion is accommodated in the terminal housing 83. The quick connection terminal portion includes two quick connection terminal members 87, two conductive terminal members 88, a terminal holding member e (an upper holding member 89a and a lower holding member 89b), and a release button. 90. As shown in FIG. 15, the terminal block 81 of the present embodiment has a collar portion 84 (fixed portion) positioned by a locking portion 30 b of the terminal mounting portion 30 provided on the fixture body 21 of the lighting fixture 11, and a screw or the like. The fixing member 86 is fixed to the mounting surface portion 30a.

  The quick connection terminal member 87 is formed by cutting and bending a single conductive metal plate. The quick connection terminal member 87 includes a side plate portion 87a, a first extension portion 87b, a first pressing piece 87c, a support piece 87d, a second extension portion 87e, and a second pressing piece 87f. The pair of quick connection terminal members 87 are disposed in the terminal housing 83 so as to face each other with the release button 90 interposed therebetween.

  The side plate portion 87a is a substantially rectangular and flat portion. The first extension portion 87b is a pair of square plate-like portions that extend inward in the direction orthogonal to the side plate portion 87a from both lateral ends of the side plate portion 87a on the upper side of the side plate portion 87a. The first pressing piece 87c is a pair of bent plate-like spring pieces extending from the lower end of the first extending portion 87b and approaching downward. The support pieces 87d are a pair of square plate-like portions that extend inward in a direction orthogonal to the side plate portion 87a by cutting the vicinity of both lateral ends of the side plate portion 87a. The support piece 87d supports the lower end of the upper holding member 89a disposed under the release button 90.

  The second extending portions 87e are a pair of square plate-like portions that extend inward in the direction orthogonal to the side plate portion 87a from both lateral ends of the side plate portion 87a on the lower side of the side plate portion 87a. . The second pressing piece 87f is a pair of bent plate-like spring pieces extending from the upper end of the second extending portion 87e and approaching upward.

  The conductive terminal member 88 is a bar-shaped conductive metal member having a U shape in cross section. The vertical dimension (length dimension) of the conductive terminal member 88 is substantially the same as the vertical dimension of the quick connection terminal member 87. The conductive terminal member 88 is held in a state where the middle part in the vertical direction is engaged with the conductive terminal holding part 89c of the upper holding member 89a, and the lower end part is positioned in the concave part 89g of the lower holding member 89b. The quick connection terminal member 87 is disposed at the center in the short direction.

  The terminal holding member 89 includes an upper holding member 89a and a lower holding member 89b, which are insulating resin members.

  The upper holding member 89a has a conductive terminal holding portion 89c and an engaging portion 89e.

  The conductive terminal holding portion 89 c is a concave portion, and is a portion that engages and holds the midway portion in the longitudinal direction of the conductive terminal member 88.

  The engaging portion 89e is a plate-like portion that extends downward from the lower end of the conductive terminal holding portion 89c. Both end portions in the width direction of the engaging portion 89e are portions that are engaged with a release button insertion portion 83h (see FIG. 10) of the engaged portion 83d formed on the inner wall of the tubular portion 83b of the terminal housing 83. . The engaging portion 89e is disposed between the pair of fast-coupling terminal members 87 that are opposed to each other on the lower side of the terminal housing 83, and serves as a partition that separates the pair of fast-coupling terminal members 87. Fulfill. That is, the engaging portion 89e is positioned so as to separate the different poles in the lower portion of the pair of quick connection terminal members 87. By providing the engaging portion 89e at this position, it is possible to take a distance from the different poles of the pair of quick connection terminal members 87 even in a narrow space. A lower holding member 89b is disposed below the engaging portion 89e.

  The lower holding member 89b is a member that has a substantially rectangular parallelepiped shape and is fitted to the lower end side of the cylindrical portion 83b of the terminal housing 83. The lower holding member 89b is engaged with an insertion hole 89f for inserting a wiring extending from the power supply unit of the electric appliance, a recess 89g for positioning the conductive terminal member 88, and an engaged claw portion 83e of the terminal housing 83. And a pair of engaging claw portions 89h fixed to each other and a lower end flange portion 89m engaged with a recess formed at the lower end of the terminal housing 83. A pair of insertion holes 89n for inserting a core wire of the electric wire is provided at the bottom (back) of the insertion hole 89f. When the core wire of the electric wire is inserted into the insertion hole 89n, the core wire of the electric wire is sandwiched between the conductive terminal member 88 of the quick connection terminal portion and the second pressing piece 87f. When the lower holding member 89 b is fitted into the terminal housing 83, the lower surface of the lower holding member 89 b is substantially flush with the lower surface of the flange portion 84.

  The release button 90 is used for removing the core wire of the electric wire sandwiched between the first pressing piece 87c and the conductive terminal member 88 by expanding between the pair of first pressing pieces 87c of the quick connection terminal member 87. The release button 90 has a plate-like substrate, and a convex portion 90a for expanding between the pair of first pressing pieces 87c on both surfaces of the substrate, and a portion to be inserted inserted into the release button insertion portion 83h. 90b. The release button 90 is arranged such that the tip can be pushed into the central long hole of the electric wire insertion surface 83c. By pushing the tip of the release button 90 downward, the gap between the pair of first pressing pieces 87c of the quick connection terminal member 87 is expanded and the electric wire held between the first pressing piece 87c and the conductive terminal member 88 is removed. The core wire can be removed. The release button 90 is disposed between a pair of fast connection terminal members 87 disposed to face each other, and serves as a partition wall that separates the pair of fast connection terminal members 87. That is, the release button 90 is positioned so as to separate the different polarities of the power supply wire and the feed wiring. By providing the release button 90 at this position, it is possible to secure the distance between the different poles in the upper part of the terminal block 81 that becomes the connection portion of the power supply wire and the feed wiring even in a narrow space.

  The terminal housing 83 is a vertically long and substantially cylindrical shape that can be embedded in the through hole H of the attached portion C. The terminal housing 83 is formed by electrically insulating transparent or translucent resin (polycarbonate in the present embodiment) entirely or partially. The terminal housing 83 accommodates the above-described quick connection terminal portion therein. With this configuration, it is easy to confirm from the outside the quick connection terminal portion that is the internal structure of the terminal housing 83, and it is easy to understand the loss of the parts constituting the quick connection terminal portion. Further, if the terminal housing 83 is formed of polycarbonate as in this embodiment, impact resistance and dimensional stability can be increased. In addition, since polycarbonate is more transparent than other resin materials, it is easy to check the internal structure.

  The terminal housing 83 has an electric wire introduction part 83a, a cylindrical part 83b, and a fixing part. The fixing portion is formed to extend so as to intersect the cylindrical portion 83b. The fixing portion is formed to be attachable to the appliance main body of the electric appliance. In the following description, the fixing portion will be described as a collar portion 84 as an example. The electric wire introduction part 83a has a flat electric wire insertion surface 83c at the upper end.

  The wire introduction part 83a has an opening formed in the wire insertion surface 83c, and a plurality of (four in this embodiment) wire insertion holes 82 into which core wires such as power supply wires and feed wiring wires are inserted, and a release button. And an elongated hole exposing the upper end of 90. The electric wire insertion surface 83c is engraved with the letters “power” on the side of one collar part 84 and “feed” on the side of the other collar part 84 (see FIG. 4).

  The electric wire insertion hole 82 is a substantially cylindrical space communicated along the vertical direction of the electric wire introduction portion 83a. Two insertion holes 82 for the electric wire of this embodiment are formed for each of the power supply wire and the feed wiring. The wire insertion hole 82 is closer to one flange portion 84 side than the pair of flange portions 84 (in FIG. 4, the side marked “power” on the wire insertion surface 83c), It is composed of a feed wiring wire insertion hole 82b closer to the other flange portion 84 (in FIG. 4, the side marked “feed” on the wire insertion surface 83c). In this way, by setting the positions of the power supply wire insertion hole and the feed wiring insertion hole in the wire insertion hole 82, a lateral force is applied to the terminal block 81 due to the weight of the power supply wire and the feed wiring. The terminal block 81 is not easily tilted.

  The cylindrical portion 83b is formed to extend in the electric wire insertion direction. The cylindrical portion 83b has a substantially rectangular parallelepiped internal space. Inside the cylindrical portion 83b, a pair of fast connection terminal members 87, a pair of conductive terminal members 88, a terminal holding member 89 (upper holding member 89a, lower holding member 89b) and a release button 90 are provided as a quick connection terminal portion. It is housed in an assembled state. The cylindrical portion 83b has an engaged portion 83d and an engaged claw portion 83e. The engaged portion 83d is a concave portion that extends a predetermined length in the vertical direction on the inner wall of the tubular portion 83b and engages with the engaging portion 89e of the upper holding member 89a. The engaged claw portion 83e is a through hole penetrating the surface of the pair of flange portions 84 in the vicinity of the lower end of the cylindrical portion 83b, and the engagement claw portion 89h of the lower holding member 89b is engaged therewith.

  The terminal housing 83 has ribs 83f at portions where the cylindrical portion 83b and the fixing portion (the flange portion 84) intersect. The rib 83f is a portion that protrudes in the extending direction of the flange portion 84 and that extends linearly along the vertical direction of the tubular portion 83b. The rib 83 f is extended on the outer peripheral surface of the terminal housing 83 so as to gradually protrude from a midway portion in the vertical direction toward the upper surface of the flange portion 84. The rib 83f is formed in a substantially square shape in cross-sectional shape. It is preferable that at least one rib 83f is formed with respect to one flange portion 84. In the present embodiment, two ribs 83f are formed for one flange portion 84. The rib 83 f functions as a reinforcing rib for reinforcing the terminal housing 83. Thereby, the bending strength of the terminal block 81 can be improved.

  The cylindrical portion 83b has a concave portion 83g on the outer peripheral surface. The recessed part 83g is provided in the outer wall part corresponding to the to-be-engaged part 83d provided in the inner wall of the cylindrical part 83b, and follows an up-down direction from the upper end of the cylindrical part 83b to the upper end of the to-be-engaged claw part 83e. It is extended. Thus, by providing the concave portion 83g on the outer peripheral surface, as shown in FIG. 10B, the thickness is uniform with other portions adjacent to the concave portion 83g, and uneven thickness is prevented. The moldability of the part 83b is improved.

  The fixing portion (the flange portion 84) is provided on the opposite side of the terminal housing 83 from the wire introduction portion 83a so as to intersect the cylindrical portion 83b. In the present embodiment, the two flange portions 84 are formed as the fixing portions so as to extend in different directions from the lower end of the cylindrical portion 83b. The collar portion 84 is a pair of collar-shaped portions having a substantially semi-elliptical shape. Such a fixing portion can be appropriately attached without the terminal block 81 being inclined when the terminal block 81 is attached to the appliance main body of the electric appliance, rather than the fixing portion that does not intersect the cylindrical portion 83b. In addition, when a pressure is applied in a direction orthogonal to the cylindrical portion 83b, it is less likely to incline in a direction orthogonal to the cylindrical portion 83b than a fixed portion that does not intersect the cylindrical portion 83b. As a result, even when attached to the appliance main body of the electric appliance, sufficient strength is ensured and the structure of the electric appliance is not complicated. In addition, since the fixing portion is provided so as not to overlap the power supply introduction portion 83a and the cylindrical portion 83b in plan view, the size of the power supply introduction portion 83a and the cylindrical portion 83b is not increased. Thereby, like the lighting fixture 11 using the terminal block 81 mentioned later, only a part of the terminal block 81 (a part of the power supply introduction part 83a and the cylindrical part 83b) is inserted into the through hole H provided in the attached part C. Need only be inserted, and it is not necessary to provide a large through hole H in the attached portion C.

  On the lower side surface of the collar portion 84, a boss portion 84a having a circular shape in plan view and a convex shape downward is provided. The boss portion 84 a is disposed on one side of the corner portion on the lower side surface of each of the pair of flange portions 84. The boss portion 84a can be engaged with, for example, a recess provided at a corresponding position on the mounting surface portion 30a. The boss portion 84 a can position the terminal block 81 with respect to the instrument body 21 by engaging with the concave portion of the attachment surface portion 30 a. The boss portion 84a serves as a guide for guiding the terminal block 81 to an appropriate mounting position with respect to the appliance main body of the electric appliance such as the appliance main body 21.

The pair of collar portions 84 are formed in different shapes in plan view. One collar portion 84 has a substantially semi-elliptical shape in plan view. The other flange portion 84 has a substantially oval shape in plan view and a shape in which a part of the outer peripheral end is notched linearly along a direction orthogonal to the extending direction of the flange portion 84. Further, a convex portion 84b having a semicircular shape in plan view is provided at the center of the notched portion of the other flange portion 84. Thus, by making the shape of the pair of flange portions 84 different from each other, it becomes a marker for recognizing the orientation of the terminal block 81. The operator can perform the assembly work while easily recognizing the orientation of the terminal block in the electric appliance.
In addition, the shape of a pair of collar part 84 is not limited to this embodiment, The shape of a pair of collar part 84 mutually differs, and it should just be distinguished as a marker.

Further, the pair of flange portions 84 have through holes 84 c and 84 d through which the fixing member 86 is inserted. The through hole 84c of the one collar portion 84 is a long hole having an oval shape in plan view. The insertion hole 84d of the other collar part 84 is a circular hole having a circular shape in plan view. The through-hole 84c of the one collar portion 84 is for play during assembly, and fine adjustment can be performed to provide the terminal block 81 at an appropriate position.
In addition, in this embodiment, although the fixing | fixed part is made into a pair of collar part 84, it does not specifically limit. For example, the flange portion may be extended in all directions, and the flange portion may be formed over the entire periphery of the lower end of the cylindrical portion 83b.

In the terminal block 81, when connecting the core wires of the power supply wires and the feed wiring wires, the core wires of the power supply wires and the feed wiring wires are inserted into the wire insertion holes 82 along the vertical direction of the instrument main body 21 on one end side (upper end side). Plugged into. The core wire of the inserted electric wire is sandwiched and electrically connected to the first pressing piece 87c of the quick connection terminal member 87 and one end side of the conductive terminal member 88. On the other end side (lower end side) of the terminal block 81, the core wire of the power supply unit 31 is inserted into the insertion hole 89n. The inserted core wire of the power supply unit 31 is sandwiched and electrically connected to the second pressing piece 87f of the quick connection terminal member 87 and one end side of the conductive terminal member 88. In this way, the power supply wire or the feed wiring wire and the wiring of the power supply unit 31 are electrically connected via the terminal block 81.
When the upper end of the release button 90 is pushed downward with a tapered tool or the like when the terminal block 81 removes the core wire of the power supply wire or the feed wiring wire (at the time of release), the convex portion 90a of the release button 90 is 1 The pressing piece 87c is expanded. Thereby, it becomes possible to pull out the core wire of the electric wire held between the first pressing piece 87c and the conductive terminal member 88.

  In the terminal block 81, the penetration direction of the through hole 84 for inserting the fixing member 86 is the same as the insertion direction of the electric wire. The release operation direction of the release button 90 is the same as the through direction of the through hole 84. That is, the mounting direction of the terminal block 81 (arrow X direction shown in FIG. 7) and the wire insertion direction / wire release direction (arrow Y direction shown in FIG. 7) are the same. Since the mounting direction of the terminal block 81 and the direction in which the electric wire is inserted or released are the same, it is difficult to apply an orthogonal pressure to the tubular portion 83b when inserting or releasing the electric wire. Therefore, it is difficult to give extra stress to the fixing portion where the terminal block 81 is attached to the appliance body of the electric appliance or the base portion thereof.

  The cover 85 is formed of an elastic electrically insulating resin such as a silicone resin. The cover 85 has a bottomed cylindrical shape with one end opened, and the inner shape of the cover 85 is formed to match the outer shape of the electric wire introduction portion 83 a of the terminal housing 83. The cover 85 has a shape in which a substantially circular diametrically opposed portion in a plan view is cut out linearly. The cover 85 has an arcuate surface portion 85a and a flat surface portion 85b as outer peripheral surfaces. The cover 85 is attached to the electric wire introducing portion 83a of the terminal housing 83 so as to cover the electric wire insertion surface 83c and the electric wire insertion hole 82. Core wires of power wires such as power wires and feed wiring wires are pierced so as to penetrate the cover 85, inserted into the wire insertion holes 82, and electrically connected to the quick connection terminal portion. By connecting in this way, it is possible to prevent foreign matters such as dust and water droplets from entering the insertion hole 82 of the electric wire.

  At the lower end of the circular arc surface portion 85a, there is a locking portion 85c extending inward. The locking portion 85c is locked to the locked portion 83p that protrudes outside the lower portion of the electric wire introduction portion 83a. That is, the cover 85 has a structure that is caught by at least a part of the wire introduction portion 83 a of the terminal block 81. Thereby, the cover 85 can be easily attached to an appropriate position of the electric wire introduction portion 83a, and further, the cover 85 can be prevented from being bent when the electric wire is inserted into the cover 85 by being inserted.

Below, the electric appliance using the terminal block of this embodiment is demonstrated using figures.

In addition, the external shape of the lighting fixture 11 is not limited to this embodiment. Other than a substantially circular shape in plan view, for example, an elliptical shape, a square shape, a rectangular shape, a polygonal shape, a sector shape, or a combination thereof can also be used.
Further, a through-hole H having a circular shape in plan view is provided in the attached portion C to which the luminaire 11 is attached. The through-hole H is a hole for inserting an electric wire such as a power supply wire or a feed wiring wire connected to an external commercial power source.

The instrument main body 21 is a substantially circular plate-shaped member in plan view, and is a flat dish-shaped member. The instrument main body 21 holds the power supply unit 31, the light source unit 41, the diffusion plate 51, the cover unit 61, the back cover unit 71, the terminal block 81, and the like. Specifically, the instrument main body 21 accommodates the power supply unit 31 in a power supply accommodating unit 29 described later on the attachment surface side, and the terminal block 81 and the back cover unit 71 are attached on the attachment surface side, and on the irradiation surface side. It is a member to which the light source unit 41, the diffusion plate 51, and the cover unit 61 are attached.
