(Implementation form) Hereinafter, the lighting equipment of the embodiment will be described. Fig. 1 is an exploded perspective view of the lighting fixture of the embodiment. Fig. 2 is an enlarged view of area II in Fig. 1, which is a perspective view of the appearance of the connector for lighting equipment of the embodiment viewed from below. Fig. 3 is an external perspective view of the connector for lighting equipment of the embodiment viewed from above. Furthermore, in FIGS. 1 to 3, there is also a ceiling junction box 200 installed on a ceiling and other structures.

As shown in FIGS. 1 to 3, the lighting fixture 300 includes a connector 100 for lighting fixtures, a fixture body 310, light source units 320a and 320b, a connector 330, a cover 340, and a lamp cover 350. The main body 310 of the appliance is provided with a mounting hole 360.

The appliance body 310 is provided with a light source unit 320a and a light source unit 320b, and a connector 330 electrically connected to the light source unit 320a and the light source unit 320b. Furthermore, a circular mounting hole 360 is provided in the central part of the main body 310 of the appliance.

The light source unit 320a and the light source unit 320b are light sources each having a plurality of LEDs inside, and emit light toward the lampshade 350 (below), for example.

The connector 330 is a connector connected to the connector 100 for lighting equipment. By connecting the connector 330 to the connector 100 for lighting equipment, the connector 100 for lighting equipment and the equipment main body 310 are electrically connected.

The lampshade 350 is a translucent optical member, and the shape of the lampshade 350 in a plan view is a rectangle with rounded corners. The lampshade 350 is in a form of covering the bottom surface of the main body 310 of the apparatus, and is installed to the main body 310 of the apparatus. The shape of the lampshade 350 in a plan view may also be circular.

The connector 100 for luminaires is a connector for connecting the ceiling junction box body 200 and the luminaire main body 310 of the luminaire 300. The lighting fixture connector 100 includes a housing 110, and has a first terminal 121 and a second terminal 122 having an L-shaped cross-section and protrudes from the first surface 111a of the housing 110. In a state where the first terminal 121 is inserted into the insertion hole 211 and the second terminal 122 is inserted into the insertion hole 212, the lighting fixture connector 100 is rotated in the installation direction relative to the ceiling junction box body 200, whereby This allows the connector 100 for lighting equipment to be mounted to the ceiling junction box body 200. In other words, the connector 100 for lighting equipment is mechanically and electrically connected to the ceiling junction box body 200.

In addition, when the lighting fixture connector 100 rotates until the first terminal 121 reaches the end of the insertion hole 211 and the second terminal 122 reaches the end of the insertion hole 212, the protrusion 181 that is pushed toward the ceiling junction box body 200 is pressed. The position will overlap with the position of the insertion hole 212, and the protrusion 181 will protrude from the first surface 111 a of the housing 110 and penetrate into the insertion hole 212. In this state, the rotation of the lighting fixture connector 100 relative to the ceiling junction box body 200 is restricted. In other words, the rotation of the lighting fixture connector 100 relative to the ceiling junction box body 200 is locked.

Furthermore, the first locking member 131 and the second locking member 132 protrude from the side wall of the housing 110; and the first locking member 131 and the second locking member 132 will be accommodated in the torsion force of the housing 110 The spring 170 (not shown in FIGS. 1 to 3. It is shown in FIGS. 4 to 7 described later.) is pushed from the inside of the housing 110 to the outside.

The user pushes the appliance main body 310 upward so that the housing 110 of the lighting appliance connector 100 is inserted into the mounting hole 360. At this time, the inner peripheral surface of the mounting hole 360 abuts against the inclined surfaces of the edges of the first locking member 131 and the second locking member 132, and the first locking member 131 and the second locking member 132 resist the torsion spring The pressing force of 170 is pushed to the inside of the housing 110.

Once the first locking member 131 and the second locking member 132 pass through the mounting hole 360, the inner peripheral surface of the mounting hole 360 and the inclined surface of the edge of the first locking member 131 and the second locking member 132 are released Abut. As a result, the first locking member 131 and the second locking member 132 will protrude to the outside of the housing 110 due to the pressing force of the torsion spring 170 in the housing 110. In this way, the peripheral portion of the mounting hole 360 of the device main body 310 is locked to the first locking member 131 and the second locking member 132.

After that, the user connects the connector 330 to the connector insertion port 150 provided on the bottom side of the housing 110 of the connector 100 for lighting equipment, and installs the cover 340 covering the mounting hole 360 from the bottom side, and the lamp cover 350. In this way, the mechanical and electrical installation of the luminaire 300 to the ceiling junction box body 200 is completed.

In addition, the removal method of the lighting fixture 300 is as follows. The user first removes the lamp cover 350 and the cover 340, and then removes the connector 330 from the connector insertion port 150.

Next, the user pulls the first operating lever 161 and the second operating lever 162 from the central part of the housing 110 to the outside, respectively. In this way, the first locking member 131 and the second locking member 132 move to the inside of the housing 110. Thereby, the user can remove the fixture main body 310 from the connector 100 for lighting fixtures.

Furthermore, the user can pull out the protrusion 181 from the insertion hole 212 by pressing the unlock button 140 to unlock the lock. If the user rotates the lighting fixture connector 100 in the removal direction with respect to the ceiling junction box body 200 while pressing the unlock button 140, the lighting fixture connector 100 can be removed from the ceiling junction box body 200.

[Structure of connector for lighting equipment] Next, the structure of the connector 100 for lighting equipment will be described with reference to FIGS. 4 and 5 in addition to FIGS. 1 to 3. Fig. 4 is an exploded perspective view of the lighting fixture connector 100 viewed from above. Fig. 5 is an exploded perspective view of the lighting fixture connector 100 viewed from below. In addition, in FIGS. 4 and 5, the screws for fixing the members to each other are not shown in the drawings.

The connector 100 for lighting equipment includes a housing 110, a first terminal 121, a second terminal 122, a ground terminal 123, a first locking member 131, a second locking member 132, an unlock button 140, and a first operating lever 161 , The second operating lever 162, the torsion spring 170, and the locking portion 180.

The housing 110 is a substantially flat cylindrical member, and accommodates various components included in the joint 100 for lighting equipment. The housing 110 has a first surface 111a facing the ceiling junction box body 200, and a second surface 112a opposite to the first surface 111a. The housing 110 specifically has a main body 111 on the side of the first surface 111a and a cover 112 on the side of the second surface 112a.

The main body 111 is a substantially bottomed cylindrical (flat) member that opens on the side of the second surface 112a. The main body 111 is formed of, for example, an insulating resin material, and forms the housing 110 of the lighting fixture connector 100 together with the outer cover 112.

A portion of the main body 111 facing the ceiling junction box body 200 is provided with a terminal insertion hole 111a1, a terminal insertion hole 111a2, and a terminal insertion hole 111a3. The edge portion 121a of one side of the first terminal 121 protrudes from the terminal insertion hole 111a1, the edge portion 122a of one side of the second terminal 122 protrudes from the terminal insertion hole 111a2, and the edge portion 123a of one side of the ground terminal 123 protrudes from the terminal insertion hole 111a3.

Furthermore, an opening 111b is provided in a portion of the main body 111 facing the ceiling junction box body 200. A protrusion 181 having a locking portion 180 protrudes from the opening 111b.

The side wall of the main body 111 is provided with a first opening 111c1 and a second opening 111c2. The first locking member 131 protrudes from the first opening 111c1 toward the outer side of the main body 111. The second locking member 132 protrudes from the second opening 111c2 toward the outer side of the main body 111.

A connector insertion port 150 is provided on the inner side of the main body 111. The connector insertion opening 150 is a part that extends cylindrically from the inner surface of the part of the main body 111 facing the ceiling junction box body 200 toward the second surface 112a. The connector insertion port 150 is exposed to the outside from the housing 110 through the opening 112b provided in the center of the outer cover 112, and the connector 330 of the appliance main body 310 is pluggable and connected. The shape of the connector insertion opening 150 in a plan view is substantially T-shaped, and the connector 330 has a corresponding shape. The connector insertion opening 150 is an example of a recess provided on the second surface 112a side of the housing 110.

The cover 112 is a metal plate-shaped member covering the bottom surface side of the main body 111. The outer cover 112 constitutes the second surface 112 a of the housing 110. In other words, at least a part of the second surface 112a side of the housing 110 is formed of metal. In the center of the outer cover 112, an opening 112b is provided. The connector insertion port 150, the first operated portion 161a of the first operating lever 161, and the second operated portion 162a of the second operating lever 162 are exposed to the outside through the opening 112b.

The first terminal 121, the second terminal 122, and the ground terminal 123 are plate-shaped members made of metal. The first terminal 121, the second terminal 122, and the ground terminal 123 are fixed to the inside of the main body 111 with screws. The edge portion 121a of one side of the first terminal 121 protrudes from the terminal insertion hole 111a1 provided in the housing 110. The edge 121b on the other side of the first terminal 121 is disposed in the connector insertion opening 150. Similarly, the edge portion 122 a of one side of the second terminal 122 protrudes from the terminal insertion hole 111 a 2 provided in the housing 110. The edge portion 122b on the other side of the second terminal 122 is disposed in the connector insertion opening 150. The edge portion 123 a on one side of the ground terminal 123 protrudes from the terminal insertion hole 111 a 3 provided in the housing 110, and the edge portion 123 b on the other side of the ground terminal 123 is disposed in the connector insertion opening 150.

The first terminal 121 and the second terminal 122 are a pair of power supply terminals for the lighting fixture 300 to receive power from the ceiling junction box body 200. The edge 121a of one side of the first terminal 121 is inserted into the insertion hole 211, and the edge portion 122a of one side of the second terminal 122 is inserted into the insertion hole 212, so that the first terminal 121 and the second terminal 122 are A pair of power supply terminals in the ceiling junction box body 200 are electrically connected. Although the luminaire 300 receives, for example, the supply of AC power from the ceiling junction box body 200, it may also receive the supply of DC power.

Furthermore, the edge portion 121a on one side of the first terminal 121 and the edge portion 122a on one side of the second terminal 122 are respectively bent into an L-shape. If the edge portion 121a of one side of the first terminal 121 penetrates the insertion hole 211 and the edge portion 122a of one side of the second terminal 122 penetrates the insertion hole 212, the lighting fixture connector 100 is rotated, and the lighting fixture connector 100 will be buckled on the ceiling junction box body 200. In other words, the first terminal 121 and the second terminal 122 are also used to mechanically connect the connector 100 for lighting equipment to the ceiling junction box body 200.

The ground terminal 123 is a terminal used to improve the safety of the connector 100 for lighting equipment. By inserting the edge portion 123 a of one side of the ground terminal 123 into the insertion hole 213, the ground terminal 123 is electrically connected to the ground terminal in the ceiling junction box body 200. Unlike the first terminal 121 and the second terminal 122, the edge portion 123a of one side of the ground terminal 123 is not bent, and the ground terminal 123 is not used for mechanical connection of the connector 100 for lighting equipment. However, the edge portion 123a of one side of the ground terminal 123 may be bent so that the ground terminal 123 is used for mechanical connection of the connector 100 for lighting equipment. In addition, the connector 100 for lighting equipment does not necessarily have the ground terminal 123, and the ground terminal 123 may be omitted.

The edge 121b of the other side of the first terminal 121, the edge 122b of the other side of the second terminal 122, and the edge 123b of the other side of the ground terminal 123 are in a state where the connector 330 is connected to the connector insertion port 150 , And connect with the metal terminal in the connector 330.

Alternatively, it may be configured that the length of the portion protruding from the first surface 111a of the edge portion 123a of one side of the ground terminal 123 is greater than that of the edge portion 121a of one side of the first terminal 121 that protrudes from the first surface 111a The length of the portion of the second terminal 122 and the length of the portion protruding from the first surface 111a of the edge portion 122a of one side of the second terminal 122. The length referred to here is, more specifically, the length in the Z-axis direction.

Thereby, when the lighting fixture connector 100 is installed to the ceiling junction box body 200, the ground terminal 123 is easily electrically connected to the terminals in the ceiling junction box body 200 before the first terminal 121 and the second terminal 122. Therefore, it is possible to improve the safety at the time of attaching the connector 100 for lighting equipment to the ceiling junction box body 200.

Similarly, the edge portion 123b on the other side of the ground terminal 123 may also protrude more toward the second surface 112a than the edge portion 121b on the other side of the first terminal 121 and the edge portion 122b on the other side of the second terminal 122 .

Thereby, when the appliance main body 310 and the lighting fixture connector 100 are electrically connected, the ground terminal 123 is easily electrically connected to the appliance main body 310 earlier than the first terminal 121 and the second terminal 122. Therefore, the safety at the time of attaching the fixture main body 310 to the connector 100 for lighting fixtures can be improved.

The first locking member 131 and the second locking member 132 are resin-made members used by the lighting fixture connector 100 to hold the fixture main body 310. In other words, the first locking member 131 and the second locking member 132 are members for locking the fixture body 310 to the lighting fixture connector 100, and the fixture body 310 is locked to the first locking member 131 and the second locking member 131 and the second locking member 132. Locking member 132.

The first locking member 131 is pushed by the torsion spring 170 from the inside of the housing 110 to the outside, and protrudes from the first opening 111c1 toward the outside of the housing 110. The second locking member 132 is pushed by the torsion spring 170 from the inside of the housing 110 to the outside, and protrudes toward the outside of the housing 110 from the second opening 111c2.

The torsion spring 170 is an elastic member made of metal, and pushes the first locking member 131 and the second locking member 132 to the outside of the housing 110. The torsion spring 170 causes the first locking member 131 to protrude from the first opening 111c1 provided on the side wall of the housing 110 toward the outer side of the housing 110. Furthermore, the torsion spring 170 causes the second locking member 132 to protrude from the second opening 112c2 provided on the side wall of the housing 110 toward the outside of the housing 110.

Specifically, the torsion spring 170 has a first arm 171 connected to the first locking member 131, a second arm 172 connected to the second locking member 132, and a first arm 171 and a second arm connected to each other. The winding portion 173 of the arm portion 172. In other words, the torsion spring 170 includes a first arm portion 171 and a second arm portion 172 connected through the winding portion 173.

The winding portion 173 is a portion where the linear metal member constituting the base of the torsion spring 170 is spirally wound. A protrusion 113 provided inside the casing 110 passes through the winding part 173. The protrusion 113 is cylindrical, in other words a sleeve. The protrusion 113 is provided with a screw hole for inserting a screw for fixing the cover 112 to the main body 111.

The first locking member 131 moves along the Y-axis direction by operating the first operating lever 161. The second locking member 132 moves along the Y-axis direction by operating the second operating lever 162.

The first operating lever 161 and the second operating lever 162 are resin-made members operated to remove the fixture body 310 from the lighting fixture connector 100.

The first operating lever 161 is a member that is connected to the first locking member 131 and moves the first locking member 131 in the Y-axis direction. The first operating lever 161 has a first operated portion 161a and a first connecting portion 161b.

The first operated portion 161a is operated by the user to move the first locking member 131 toward the inner side of the housing 110. The first operated portion 161a protrudes from the opening 112b provided in the outer cover 112 to the outside of the housing 110. The opening 112b is an example of an opening provided on the second surface 112a side of the housing 110.

The first connecting portion 161b connects the first operated portion 161a and the first locking member 131. The first connecting portion 161b is arranged in the concave portion 131a of the first locking member 131, whereby the first operating lever 161 and the first locking member 131 are engaged with each other. That is, the first operated portion 161a and the first locking member 131 are connected. By pulling the first operated portion 161a from the central part of the housing 110 toward the outside, the first locking member 131 moves to the inside of the housing 110 against the elastic force of the torsion spring 170.

The second operating lever 162 is a member for moving the second locking member 132 in the Y-axis direction. The second operating lever 162 has a second operated portion 162a and a second connecting portion 162b.

The second operated portion 162 a is operated by the user to move the second locking member 132 toward the inner side of the housing 110. The second operated portion 162 a protrudes from the opening 112 b provided in the outer cover 112 to the outside of the housing 110. The opening 112b is an example of an opening provided on the second surface 112a side of the housing 110.

The second connecting portion 162b connects the second operated portion 162a and the second locking member 132. The second connecting portion 162b is arranged in the recess 132a of the second locking member 132, whereby the second operating lever 162 and the second locking member 132 are engaged with each other. That is, the second operated portion 162a and the second locking member 132 are connected. By pulling the second operated portion 162a from the central part of the housing 110 toward the outside of the housing 110, the second locking member 132 moves to the inside of the housing 110 against the elastic force of the torsion spring 170.

In this way, the user pulls the first operated portion 161a and the second operated portion 162a from the central part of the housing 110 to move the first locking member 131 and the second locking member 132 to the housing. In the body 110, the device main body 310 can be removed from the lighting device connector 100.

Furthermore, the shape, size, and arrangement of the first locking member 131 and the second locking member 132 are symmetrical. On the other hand, the shape and size of the first operating lever 161 and the second operating lever 162 are slightly different. The first operating lever 161 has a larger shape than the second operating lever 162 when viewed from a direction perpendicular to the second surface 112a in order to suppress the positional deviation of the torsion spring 170.

The locking portion 180 is a member for restricting the movement of the lighting fixture connector 100 relative to the ceiling junction box body 200 so as to maintain the lighting fixture connector 100 in a state where it is normally installed on the ceiling junction box body 200. The lock portion 180 includes a protrusion 181, a spring hole 182 into which a coil spring (not shown) is inserted, and a groove portion 183.

The coil spring inserted into the spring hole 182 has one end abutting the bottom in the spring hole 182 and the other end abutting the inner surface of the outer cover 112. Thereby, the locking portion 180 is pressed from the second surface 112a side to the first surface 111a side. Once the lighting fixture connector 100 is rotated so that the first terminal 121 reaches the end of the insertion hole 211 and the second terminal 122 reaches the end of the insertion hole 212, the position of the protrusion 181 overlaps the position of the insertion hole 212 , The protrusion 181 will protrude from the first surface 111a of the housing 110 and penetrate the insertion hole 212 due to the urging force (elastic force) of the coil spring. In this state, the rotation of the lighting fixture connector 100 relative to the ceiling junction box body 200 is restricted. That is, the rotation of the lighting fixture connector 100 with respect to the ceiling junction box body 200 is locked.

In this way, the protrusion 181 protrudes from the opening 111b provided on the first surface 111a side of the housing 110 and penetrates the insertion hole 212 provided on the ceiling junction box body 200 to restrict the lighting fixture connector 100 relative to Movement of the ceiling junction box body 200.

The unlock button 140 is a button that is provided on the side wall of the housing 110 and is pressed by a person to pull the protrusion 181 out of the insertion hole 212. The unlock button 140 is a resin-made member, and a part of it is located on the outer side of the housing 110 through a cutout provided in the side wall of the housing 110.

The convex part 141 of the unlocking button 140 is located in the groove part 183 of the locking part 180. The groove portion 183 forms an inclined groove in the X-axis direction as the moving direction of the convex portion 141; when the user presses the unlock button 140 toward the inside of the housing 110, the convex portion 141 of the unlock button 140 is The inner wall of the groove portion 183 is pushed, thereby causing the locking portion 180 to move toward the second surface 112a. As a result, the protrusion 181 is pulled out from the insertion hole 212 against the urging force (elastic force) of the coil spring. As a result, the restriction on the rotation of the lighting fixture connector 100 with respect to the ceiling junction box body 200 is released. The user can detach the lighting fixture connector 100 from the ceiling junction box body 200 by rotating the lighting fixture connector 100 with respect to the ceiling junction box body 200 while pressing the unlock button 140.

[Configuration of the first joystick] In the joint 100 for lighting equipment, restraining the positional deviation of the torsion spring 170 is an issue. For example, when the joint 100 for lighting equipment is assembled by an automatic assembly device, the stability of the assembly of the joint 100 for lighting equipment can be improved by suppressing the position deviation of the torsion spring 170.

Furthermore, the torsion spring 170 is located between the first terminal 121 and the outer cover 112 in the height direction of the connector 100 for lighting equipment. 6 is a cross-sectional view of the vicinity of the winding portion 173 of the torsion spring 170 of the joint 100 for lighting equipment.

As shown in FIG. 6, on the inner side of the housing 110, in the direction from the second surface 112 a to the first surface 111 a, the first operating rod 161, the torsion spring 170, and the first terminal 121 are sequentially arranged. In other words, the torsion spring 170 is located between the first terminal 121 and the outer cover 112. As mentioned above, the first terminal 121 is a terminal for the lighting fixture 300 to receive the power supply from the ceiling junction box body 200. Therefore, around the first terminal 121, the torsion spring 170 and other metal components need to be arranged. Insulation distance.

In particular, when the cover 112 is made of metal, in order to ensure all the insulation distances related to the first terminal 121, the distance from the first terminal 121 to the torsion spring 170 and the distance from the torsion spring 170 to the cover 112 , Both need to keep a certain degree of distance. However, if the torsion spring 170 is close to one of the first terminal 121 and the outer cover 112 due to skewed installation of the torsion spring 170, etc., it is difficult to ensure the entire insulation distance with respect to the first terminal 121.

In view of this, when the lighting fixture connector 100 is viewed from a direction perpendicular to the second surface 112a (hereinafter, it may only be described as "under a plan view"), the first operating lever 161 is connected to At least a part of the winding portion 173 of the torsion spring 170 overlaps. FIG. 7 is a diagram of the inside of the housing 110 of the lighting fixture connector 100 viewed from the side of the second surface 112a. In addition, in FIG. 7, the housing 110, the terminal insertion hole 111a1, and the protrusion 113 are shown in dashed lines.

As shown in FIG. 7, the first operating rod 161 overlaps at least a part of the winding portion 173 of the torsion spring 170. As a result, the position of the torsion spring 170 is restricted by the first operating lever 161, so that the assembly failure of the joint 100 for lighting equipment can be suppressed. Furthermore, since the contact between the torsion spring 170 and the outer cover 112 is suppressed, it is easy to ensure the entire insulation distance with respect to the first terminal 121.

In addition, the side surface 161d on the outer side of the first operating lever 161 faces the protrusion 113; and the distance L from the side surface 161d on the outer side of the first operating lever 161 to the protrusion 113 is smaller than the diameter d of the winding portion 173. The diameter d of the winding portion 173, in other words, is the wire diameter (that is, the “thickness”) of the winding portion 173.

Thereby, the first operating rod 161 can easily overlap with at least a part of the winding portion 173 of the torsion spring 170.

Furthermore, as shown in FIG. 7, the first operating rod 161 not only overlaps with at least a part of the winding part 173 but also overlaps with at least a part of the first arm part 171.

Furthermore, the first operating rod 161 also overlaps at least a part of the second arm 172. Specifically, the first operating lever 161 has a corner portion 161c, and the corner portion 161c overlaps the second arm portion 172. The corner 161c is a rounded corner with an angle of almost 90 degrees; the second operating lever 162 does not have such a corner. In other words, the corner portion 161c is a portion deliberately formed in order to overlap at least a part of the first operating lever 161 and the second arm portion 172. In addition, the first operating lever 161 may overlap with the second arm portion 172 at a portion other than the corner portion 161c. In addition, the angle of the corner portion 161c is not limited to 90 degrees. For example, the corner portion 161c may also extend to the outside more than that shown in FIG. 7, and the angle is less than 90 degrees.

In this way, the position of the torsion spring 170 can be restricted more reliably by the structure in which at least a part of the first operating rod 161 and the second arm portion 172 are overlapped.

Furthermore, as shown in FIG. 7, the corner portion 161c not only overlaps with at least a part of the second arm portion 172, but also overlaps with at least a part of the terminal insertion hole 111a1. That is, the joint 100 for lighting equipment has a part where the terminal insertion hole 111a1, the torsion spring 170, and the first operating lever 161 overlap.

Thereby, the first operating rod 161 can restrict the position of the torsion spring 170 near the terminal insertion hole 111a1.

So far, since the first operating lever 161 has a long distance from the first operated portion 161a to the corner portion 161c, when the first operated portion 161a is operated, the stress applied to the first operating lever 161 It may become larger.

In view of this, the side surface 161e on the inner side of the first operating lever 161 includes a curved surface. Accordingly, compared to the case where the inner side surface 161e is formed as a plane like the second operating rod 162, the width of the first operating rod 161 can be increased as a whole, and the first operating rod 161 can be reduced by increasing the width. The stress applied to the first operating lever 161 when the operated portion 161a is operated. In addition, the side surface 161e on the inner side of the first operating lever 161 may include a plurality of curved surfaces. Furthermore, the side surface 161d on the outer side of the first operating lever 161 may include one or more curved surfaces.

[Effects etc.] As described above, the lighting fixture connector 100 is a lighting fixture connector for connecting the ceiling junction box body 200 and the fixture main body 310 of the lighting fixture 300. The connector 100 for lighting equipment includes a housing 110 (which has a first surface 111a facing the ceiling junction box body 200 and a second surface 112a opposite to the first surface 111a); a first locking member 131, Used to lock the device body 310 to the lighting fixture connector 100; the torsion spring 170 causes the first locking member 131 to protrude from the first opening 111c1 provided on the side wall of the housing 110 toward the outside of the housing 110; and An operating lever 161 is connected to the first locking member 131 and has a first operated portion 161a. The first operated portion 161a protrudes from the opening 112b provided in the housing 110 to the outside of the housing 110 for human operation It is used to move the first locking member 131 toward the inner side of the housing 110; in a plan view, the first operating rod 161 overlaps at least a part of the winding portion 173 of the torsion spring 170.

As a result, the position of the torsion spring 170 is restricted by the first operating lever 161, so that the assembly failure of the joint 100 for lighting equipment can be suppressed. Furthermore, the variation in the insulation distance due to the positional movement of the torsion spring 170 is suppressed.

Furthermore, for example, the housing 110 has a first surface 111a facing the ceiling junction box body 200, and a second surface 112a opposite to the first surface 111a. The lighting fixture connector 100 further includes a first terminal 121 for power supply, which protrudes from the terminal insertion hole 111a1 provided on the first surface 111a of the housing 110 to the outside of the housing 110. At least a part of the second surface 112a side of the housing 110 is formed of metal; inside the housing 110, in the direction from the second surface 112a to the first surface 111a, the first operating rods 161, The torsion spring 170 and the first terminal 121.

Since the position of the torsion spring 170 is restricted by the first operating lever 161 by this, the distance from the first terminal 121 to the torsion spring 170 and the distance from the torsion spring 170 to the outer cover 112 are not easily changed. Therefore, it is easy to ensure all the insulation distances related to the first terminal 121.

Furthermore, for example, in a plan view, the lighting fixture connector 100 has a portion where the terminal insertion hole 111a1, the torsion spring 170, and the first operating lever 161 overlap.

Thereby, the first operating rod 161 can restrict the position of the torsion spring 170 near the terminal insertion hole 111a1.

Furthermore, for example, the torsion spring 170 has a first arm portion 171 and a second arm portion 172 connected through the winding portion 173. The first arm portion 171 is connected to the first locking member 131. In a plan view, the first operating rod 161 overlaps at least a part of the winding portion 173 and at least a portion of the second arm portion 172.

Thereby, the first operating lever 161 can more reliably restrict the position of the torsion spring 170.

Furthermore, for example, in a plan view, the first operating lever 161 has a corner portion 161c, and the corner portion 161c overlaps the second arm portion 172.

Thereby, the first operating rod 161 can restrict the position of the torsion spring 170 by the corner portion 161c.

Furthermore, for example, the housing 110 has a protrusion 113 that penetrates the winding portion 173; the side surface 161d on the outer side of the first operating lever 161 faces the protrusion 113; and the side surface 161d on the outer side of the first operating lever 161 reaches The distance L from the protrusion 113 is smaller than the diameter d of the winding part 173.

Thereby, the first operating rod 161 can easily overlap with at least a part of the winding portion 173 of the torsion spring 170.

Furthermore, for example, the side surface 161e on the inner side of the first operating lever includes a curved surface.

Accordingly, compared to the case where the inner side surface 161e is formed as a plane like the second operating rod 162, the width of the first operating rod 161 can be increased as a whole, and the first operating rod 161 can be reduced by increasing the width. The stress applied to the first operating lever 161 when the operated portion 161a is operated.

Furthermore, for example, the lighting fixture connector 100 further includes: a second locking member 132 for locking the fixture body 310 to the lighting fixture connector 100; and a second operating lever 162 and the second locking member 132 Is connected and has a second operated portion 162a, which protrudes from the opening 112b provided in the housing 110 to the outside of the housing 110, and is operated by a person to make the second locking member 132 face The inside of the housing 110 moves. The torsion spring 170 causes the second locking member 132 to protrude from the second opening 111c2 provided on the side wall of the housing 110 toward the outer side of the housing 110.

Thereby, the device main body 310 can be locked to the first locking member 131 and the second locking member 132. Furthermore, by operating the first operating lever 161 and the second operating lever 162, the user can remove the appliance body 310 originally locked to the first locking member 131 and the second locking member 132.

Furthermore, for example, the connector 100 for lighting equipment further includes a ground terminal 123 that protrudes from the terminal insertion hole 111a3 provided in the housing 110 to the outside of the housing 110.

In this way, by providing the lighting fixture connector 100 with the ground terminal 123, any electrical conductors (in other words, metal members) in the lighting fixture 300 including the lighting fixture connector 100 can be grounded, and the performance of the lighting fixture 300 can be improved. safety.

Furthermore, the lighting fixture 300 includes a coupling 100 for lighting fixtures and a fixture main body 310.

With this, in the lighting fixture connector 100 included in the lighting fixture 300, the position of the torsion spring 170 is restricted by the first operating lever 161, so that the assembly failure of the lighting fixture connector 100 can be suppressed. Furthermore, the variation in the insulation distance due to the positional movement of the torsion spring 170 is suppressed.
