(Implementation form) [Structure of lighting equipment] Hereinafter, the lighting fixture 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 an external perspective view 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. In addition, FIGS. 1 to 3 also illustrate a suspended ceiling lamp holder main body 200 installed on a structure such as a ceiling.

As shown in FIGS. 1 to 3, the lighting fixture 300 includes a lighting fixture connector 100, a fixture body 310, light source units 320a and 320b, a connector 330, a cover plate 340, and a lamp cover 350. The appliance body 310 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. In addition, a circular mounting hole 360 is provided in the central part of the appliance body 310.

The light source unit 320a and the light source unit 320b are each a light source provided with 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 is electrically connected to the equipment body 310.

The lampshade 350 is an optical member with translucency; the top view shape of the lampshade 350 is a rectangle with rounded corners. The lamp cover 350 is attached to the main body 310 of the apparatus so as to cover the bottom surface of the main body 310 of the apparatus. The top view shape of the lampshade 350 may also be circular.

The connector 100 for luminaires is a connector for connecting the main body 200 of the suspended ceiling lamp holder to the body 310 of the luminaire 300. The connector 100 for lighting equipment includes a housing 110; a first terminal 121 and a second terminal 122 having an L-shaped cross section protrude from the first surface 111a of the housing 110. When the first terminal 121 penetrates the through hole 211 of the main body 210 of the suspended ceiling lamp holder main body 200, and the second terminal 122 penetrates through the through hole 212, the lighting fixture connector 100 is connected to the suspended ceiling lamp holder main body. The 200 rotates in the installation direction, so that the lighting fixture connector 100 is installed to the main body 200 of the suspended ceiling lamp holder. In other words, the connector 100 for lighting equipment is mechanically and electrically connected to the main body 200 of the suspended ceiling lamp holder.

In addition, if the lighting fixture connector 100 rotates and the first terminal 121 reaches the end of the through hole 211, and the second terminal 122 reaches the end of the through hole 212, the position of the protrusion 181 biased toward the suspended ceiling lamp holder main body 200 , Coincides with the position of the through hole 212, and the protrusion 181 protrudes from the first surface 111a of the housing 110 to penetrate the through hole 212. In this state, the rotation of the lighting fixture connector 100 with respect to the suspended ceiling lamp holder body 200 is restricted. That is, the rotation of the joint 100 for lighting equipment with respect to the main body 200 of the suspended ceiling lamp holder is locked.

In addition, the first locking member 131 and the second locking member 132 protrude from the side wall of the housing 110; by the torsion spring 170 (not shown in FIGS. 1 to 3, described later in FIGS. 4 and 5), the first locking member 131 and the second locking member 132 are biased from the inside to the outside of the housing 110.

The user pushes the main body 310 upwards to insert the housing 110 of the connector 100 for lighting equipment into the mounting hole 360. At this time, the inner peripheral surface of the mounting hole 360 abuts on the inclined surfaces of the ends 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 twisting The biasing force of the spring 170 is pushed in toward the inner side of the housing 110.

If 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 will abut the inclined surfaces of the ends of the first locking member 131 and the second locking member 132 Releasing. As a result, the first locking member 131 and the second locking member 132 protrude to the outside of the housing 110 due to the biasing force given by the torsion spring 170 in the housing 110. In this way, the edge portion of the mounting hole 360 of the appliance body 310 is locked with the first locking member 131 and the second locking member 132.

Then, the user connects the connector 330 to the connector insertion opening 150 provided on the bottom side of the housing 110 of the lighting fixture connector 100, and installs the cover plate 340 covering the mounting hole 360 from the bottom side and the lamp cover 350. Thus, the mechanical and electrical installation of the luminaire 300 to the main body 200 of the suspended ceiling lamp holder is completed.

In addition, the disassembly 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 rod piece 161 and the second rod piece 162 from the central part of the housing 110 to the outside. 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 detach the luminaire main body 310 from the connector 100 for lighting equipment.

In addition, the user can pull out the protrusion 181 from the through hole 212 by pressing the lock release button 140 to release the lock.

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 to the outside of the main body 111. The second locking member 132 protrudes from the second opening 111c2 to the outside of the main body 111.

Inside the main body 111, a connector insertion port 150 is provided. The connector insertion opening 150 is a part extending cylindrically from the inner surface of the part of the main body 111 facing the suspended ceiling lamp holder main body 200 to the second surface 112a side. The connector insertion port 150 is exposed to the outside from the housing 110 through an opening 112b provided in the center of the cover portion 112, and is connected to the connector 330 of the appliance body 310 in a arbitrarily pluggable manner. The shape of the connector insertion opening 150 in plan view is slightly T-shaped, and the connector 330 has a corresponding shape. The connector insertion port 150 is an example of a recess provided on the second surface 112 a side of the housing 110.

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

The first terminal 121, the second terminal 122, and the third terminal 123 are plate-shaped members made of metal. The first terminal 121, the second terminal 122, and the third terminal 123 are fixed to the inside of the main body 111 by screws. One end 121 a of the first terminal 121 protrudes from the terminal through hole 111 a 1 provided in the housing 110. The other end 121 b of the first terminal 121 is arranged in the connector insertion port 150. Similarly, one end 122 a of the second terminal 122 protrudes from the terminal through hole 111 a 2 provided in the housing 110. The other end 122b of the second terminal 122 is arranged in the connector insertion opening 150. One end 123a of the third terminal 123 protrudes from the terminal through hole 111a3 provided in the housing 110, and the other end 123b of the third terminal 123 is arranged 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 supply from the suspended ceiling lamp holder body 200. By passing one end 121a of the first terminal 121 through the through hole 211 and making one end 122a of the second terminal 122 through the through hole 212, the first terminal 121 and the second terminal 122 are connected to the suspension type One of the main body 200 of the ceiling lamp holder is electrically connected to the power supply terminal. The luminaire 300 receives, for example, the supply of AC power from the main body 200 of the suspended ceiling lamp holder, but can also receive the supply of DC power.

In addition, one end 121a of the first terminal 121 and one end 122a of the second terminal 122 are respectively bent into an L-shape. If one end 121a of the first terminal 121 penetrates through the through hole 211, and one end 122a of the second terminal 122 penetrates through the through hole 212, the lighting fixture connector 100 is turned, the lighting fixture connector 100 hooks Clamped to the main body 200 of the suspended ceiling lamp holder. That is, the first terminal 121 and the second terminal 122 are also used for the mechanical connection of the lighting fixture connector 100 to the suspended ceiling lamp holder body 200.

The third terminal 123 is a grounding terminal for improving the safety of the connector 100 for lighting equipment. By making one end 123a of the third terminal 123 penetrate through the through hole 213, the third terminal 123 is electrically connected to the terminal in the suspended ceiling lamp holder body 200. Unlike the first terminal 121 and the second terminal 122, one end 123a of the third terminal 123 is composed of a cylindrical base 123c and a flat cylindrical large diameter portion 123d with a larger diameter than the base 123c.

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

In addition, the length of the part protruding from the first surface 111a in the one end 123a of the third terminal 123 is longer than the length of the part protruding from the first surface 111a in the one end 121a of the first terminal 121, and The length of the part protruding from the first surface 111a in the one end 122a of the second terminal 122 is longer. The length here is, more specifically, the length in the Z-axis direction. That is, in a state in which the lighting fixture connector 100 is not mounted on the suspended ceiling lamp holder main body 200, the third terminal 123 protrudes to the side of the suspended ceiling lamp holder main body 200 than the first terminal 121 and the second terminal 122 .

Thereby, when the luminaire connector 100 is installed in the suspended ceiling lamp holder body 200, the third terminal 123 is easier to connect with the fourth terminal in the suspended ceiling lamp holder body 200 than the first terminal 121 and the second terminal 122. Electrical connection. Therefore, it is possible to improve the safety when attaching the joint 100 for lighting equipment to the suspended ceiling lamp socket main body 200. In addition, the user can use the third terminal 123 to align the connector 100 for lighting equipment with the main body 200 of the suspended ceiling lamp holder.

Similarly, the other end 123b of the third terminal 123 may be further toward the second surface 112a than the other end 121b of the first terminal 121 and the other end 122b of the second terminal 122 prominent.

Thereby, when the appliance body 310 and the lighting appliance connector 100 are electrically connected, the third terminal 123 is easier to be electrically connected to the appliance body 310 before the first terminal 121 and the second terminal 122. Therefore, the safety at the time of attaching the luminaire main body 310 to the connector 100 for lighting equipment can be improved.

The first locking member 131 and the second locking member 132 are members made of resin for holding the luminaire body 310 in the lighting fixture connector 100. In other words, the first locking member 131 and the second locking member 132 are members for locking the luminaire body 310 to the connector 100 for lighting equipment; the luminaire body 310 is locked to the first locking member 131 And the second locking member 132.

The torsion spring 170 biases the first locking member 131 from the inside of the housing 110 to the outside so as to protrude from the first opening 111c1 to the outside of the housing 110. The torsion spring 170 biases the second locking member 132 from the inside of the housing 110 to the outside so that it protrudes from the second opening 111 c2 to the outside of the housing 110.

The torsion spring 170 is a metal elastic member that biases 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 to the outside of the housing 110. In addition, 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 to the outside of the housing 110.

The torsion spring 170, specifically, includes a first arm 171 connected to the first locking member 131, a second arm 172 connected to the second locking member 132, and connecting the first arm 171 and the second arm Section 172 is connected to the winding section 173. That is, the torsion spring 170 includes a first arm portion 171 and a second arm portion 172 connected via the winding portion 173.

The winding portion 173 is a portion where the original linear metal member of the torsion spring 170 is spirally wound. The protrusion 113 provided inside the casing 110 penetrates the winding portion 173. The protrusion 113 is cylindrical, in other words a hub. The protrusion 113 is provided with a screw hole into which a screw for fixing the main body 111 to the cover 112 is inserted.

By operating the first lever piece 161, the first locking member 131 is moved in the Y-axis direction. By operating the second lever piece 162, the second locking member 132 is moved along the Y-axis direction.

The first lever piece 161 and the second lever piece 162 are members made of resin that are operated in order to remove the luminaire main body 310 from the joint 100 for lighting equipment.

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

The first operated portion 161a is operated by the user in order to move the first locking member 131 to the inside of the housing 110. The first operated portion 161a protrudes from the opening 112b provided in the cover portion 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 disposed in the concave portion 131a of the first locking member 131, whereby the first lever piece 161 is engaged with the first locking member 131. 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 to 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 lever piece 162 is a member for moving the second locking member 132 in the Y-axis direction. The second lever piece 162 includes a second operated portion 162a and a second connecting portion 162b.

The second operated portion 162a is operated by the user in order to move the second locking member 132 to the inside of the housing 110. The second operated portion 162 a protrudes from the opening 112 b provided in the cover portion 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 disposed in the concave portion 132a of the second locking member 132, thereby engaging the second lever piece 162 with the second locking member 132. 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 to the outside of the housing 110, the second locking member 132 is moved 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 portion of the housing 110 to the outside, so that the first locking member 131 and the second locking member 132 can be made Move into the housing 110, and remove the luminaire main body 310 from the connector 100 for lighting equipment.

The locking portion 180 is a member used to restrict the movement of the lighting fixture connector 100 with respect to the suspended ceiling lamp holder main body 200 in order to maintain the condition that the lighting fixture connector 100 is normally mounted on the suspended ceiling lamp holder main 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 183.

The coil spring inserted into the spring hole 182 has one end abutting against the bottom in the spring hole 182 and the other end abutting against the inner surface of the cover 112. Thereby, the locking portion 180 is biased from the second surface 112a side to the first surface 111a side. If the lighting fixture connector 100 is rotated and the first terminal 121 reaches the end of the through hole 211, and the second terminal 122 reaches the end of the through hole 212, the position of the protrusion 181 coincides with the position of the through hole 212, and the protrusion 181 is caused by the coil spring. The biasing force (elastic force) protrudes from the first surface 111 a of the housing 110 and penetrates the through hole 212. In this state, the rotation of the lighting fixture connector 100 with respect to the suspended ceiling lamp holder body 200 is restricted. That is, the rotation of the joint 100 for lighting equipment with respect to the main body 200 of the suspended ceiling lamp holder 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 through hole 212 provided in the suspended ceiling lamp holder main body 200, thereby restricting the suspension of the lighting fixture connector 100 The movement of the main body 200 of the ceiling lamp holder.

The unlocking button 140 is a button provided on the side wall of the housing 110 and is pressed in order to retract the protrusion 181 from the through hole 212. The unlocking button 140 is a resin-made member that is partially located on the outside of the housing 110 through a notch provided in the side wall of the housing 110.

The convex portion 141 of the unlocking button 140 is located in the groove 183 of the locking portion 180. The groove 183 forms an inclined groove in the X-axis direction that is the moving direction of the convex portion 141. When the user pushes the unlocking button 140 into the housing 110, the convex 141 of the unlocking button 140 pushes the groove 183 The inner wall thereby moves the locking portion 180 to the second surface 112a side. As a result, the protrusion 181 resists the biasing force (elastic force) of the coil spring and withdraws from the through hole 212. Thereby, the restriction on the rotation of the suspended ceiling lamp holder main body 200 of the joint 100 for lighting equipment is released. The user presses the lock release button 140 and rotates the lighting fixture connector 100 with respect to the suspended ceiling lamp socket main body 200, so that the lighting fixture connector 100 can be detached from the suspended ceiling lamp socket main body 200.

[Structure of the third terminal and the fourth terminal] In the connector 100 for lighting equipment, the third terminal 123 is provided in the central part of the first surface 111a of the housing 110 (that is, the opposite surface facing the suspended ceiling lamp holder main body 200). The central part here is not the strictly defined central, but refers to the substantial central. The central part means, for example, the position of the rotation axis (in other words, the center position of rotation) when the lighting fixture connector 100 is rotated with respect to the suspended ceiling lamp holder main body 200, and the peripheral portion of the rotation axis. In addition, the first surface 111a may be a flat surface, a surface with unevenness, or a curved surface.

As mentioned above, the third terminal 123 is electrically connected to the fourth terminal in the main body 210 of the suspended ceiling lamp holder body 200. 6 and 7, how the third terminal 123 and the fourth terminal 220 are connected will be described. 6 is a diagram showing the internal structure of the suspended ceiling lamp holder body 200 in a state where the connector 100 for lighting equipment is not installed, and FIG. 7 is a diagram showing the internal structure of the suspended ceiling lamp holder body 200 in a state where the connector 100 for lighting equipment is installed Diagram of the internal structure.

The fourth terminal 220 shown in FIGS. 6 and 7 is formed by bending a plate spring, for example. That is, the fourth terminal 220 has elasticity. The fourth terminal 220 includes two terminal strips for clamping the third terminal 123, and the interval between the two terminal strips is narrow when the lighting fixture connector 100 is not attached. The fourth terminal 220 is grounded by wiring or the like inside the main body 210 of the suspended ceiling lamp holder main body 200.

If the lighting fixture connector 100 is attached to the suspended ceiling lamp holder main body 200, the two terminal strips of the fourth terminal 220 are stretched by the third terminal 123 and elastically deform. More specifically, the fourth terminal 220 is elastically deformed due to being stretched by the large diameter portion 123d. In addition, deformation (elastic deformation) refers to deformation based on the shape of the fourth terminal 220 in a state where the connector 100 for lighting equipment is not attached as a reference shape.

Here, since the fourth terminal 220 has elasticity, the two terminal pieces are about to return to the state where the connector 100 for lighting equipment is not attached. As a result of this, the third terminal 123 is clamped by the two terminal strips. That is, the two terminal strips of the fourth terminal 220 are in contact with the third terminal 123 in an elastically deformed state. More specifically, the two terminal pieces of the fourth terminal 220 are in contact with the large-diameter portion 123d in an elastically deformed state. In addition, the two terminal strips may be designed to be in contact with the edge e1 on the upper side of the large diameter portion 123d, or may be designed to be in contact with the edge e2 on the lower side of the large diameter portion 123d.

As mentioned above, when the first terminal 121 penetrates through the through hole 211 and the second terminal 122 penetrates through the through hole 212, the lighting fixture connector 100 is rotated to the installation direction of the suspended ceiling lamp holder main body 200, so that the lighting fixture The joint 100 is used to mount to the main body 200 of the suspended ceiling lamp holder. Here, according to the structure in which the elastic fourth terminal 220 is stretched by the large-diameter portion 123d, the large-diameter portion 123d is hooked to the fourth terminal 220 before the lighting fixture connector 100 rotates in the installation direction. In other words, the first terminal 121 and the second terminal 122 can be hooked in front of the suspended ceiling lamp holder main body 200, and the connector 100 for lighting equipment can be temporarily held by the fourth terminal 220. In this way, the user can simply install the lighting fixture connector 100 to the suspended ceiling lamp holder main body 200.

In addition, the shape of the third terminal 123 is not particularly limited. For example, it may have a conical large-diameter portion 123f like the third terminal 123e shown in FIG. 8, or the third terminal may be shown in FIG. Like 123g, the large-diameter portion 123h is positioned in the middle of the base portion 123i. 8 and 9 are diagrams showing other examples of the shape of the third terminal 123. In addition, although not shown, the third terminal 123 may have a shape in which the large diameter portion 123d does not exist. In the joint 100 for lighting equipment, only the base 123c may protrude from the terminal penetration hole 111a3.

[Modification 1] In the above-mentioned embodiment, in a state in which the lighting fixture connector 100 is attached to the suspended ceiling lamp socket main body 200, the fourth terminal 220 contacts the third terminal 123 in a deformed state. However, the third terminal 123 may be in contact with the fourth terminal 220 in a deformed state. That is, the third terminal 123 and the fourth terminal 220 may be in contact with each other in a state where at least one of them is deformed. Fig. 10 is a perspective view of the appearance of the connector for lighting equipment of Modification Example 1 as viewed from above. FIG. 11 is a diagram showing the internal structure of the main body of the suspended ceiling lamp holder of Modification 1 in a state where the connector for lighting equipment of Modification 1 is not attached. Fig. 12 is a diagram showing the internal structure of the main body of the suspended ceiling lamp socket of the modification 1 in a state where the connector for lighting equipment of the modification 1 is attached.

In addition, the following modification 1 will focus on the difference between the third terminal 1123 of the lighting fixture connector 1100 and the third terminal 123. The structure of the third terminal 1123 on the connector insertion port 150 side is similar to The third terminal 123 is the same, so its description is omitted. Regarding the structure of the suspended ceiling lamp socket main body 1200, the description will also center on the differences from the suspended ceiling lamp socket main body 200.

As shown in FIGS. 10 and 11, the third terminal 1123 of the connector 1100 for lighting equipment is formed by bending a plate spring. The third terminal 1123, specifically, is bent into an arched plate shape so as to protrude toward the suspended ceiling lamp holder main body 1200, and has elasticity. In the state where the lighting fixture connector 1100 is not mounted on the suspended ceiling lamp holder body 1200, the height of the third terminal 1123 based on the first surface 111a (that is, the third terminal 1123 is located outside the housing 110 The height of the part) is lower than that of the first terminal 121 and the second terminal 122, but can be higher.

On the other hand, as shown in FIGS. 11 and 12, the suspended ceiling lamp holder main body 1200 has a fourth terminal 1220 in the center of the surface of the main body 210 facing the lighting fixture connector 1100. A part of the fourth terminal 1220 is exposed from the main body of the suspended ceiling lamp holder body 1200 to the outside, and the other part is grounded by wiring or the like inside the suspended ceiling lamp holder body 1200. The planar shape of the fourth terminal 1220 is, for example, a circle, but it may also be other shapes such as a rectangle.

The third terminal 1123 is elastically deformed by being pushed from above. Therefore, as shown in FIG. 12, in the state where the lighting fixture connector 1100 is attached to the suspended ceiling lamp holder body 1200, the third terminal 1123 is pressed by the fourth terminal 1220, and is elastically deformed with the fourth terminal 1220 contacts.

In this way, the third terminal 1123 of the connector 1100 for lighting equipment may be configured such that the third terminal 1123 contacts the fourth terminal 1220 in a deformed state.

[Modification 2] In addition, in the connector 100 for lighting equipment, the third terminal 123 may be composed of a plurality of members. Fig. 13 is a perspective view of the appearance of the connector for lighting equipment of Modification 2 as viewed from above. FIG. 14 is a diagram showing the internal structure of the main body of the suspended ceiling lamp holder of the modification 2 in a state where the connector for lighting equipment of the modification 2 is not attached. 15 is a diagram showing the internal structure of the main body of the suspended ceiling lamp holder of the modification 2 in the state where the connector for lighting equipment of the modification 2 is attached.

As shown in Figures 13-15, the third terminal 2123 of the lighting fixture connector 2100 includes: a contact portion 2123a that contacts the fourth terminal 2220; and an elastic member 2123b that connects the contact portion 2123a to the suspended ceiling lamp holder The main body 2200 is biased.

The contact portion 2123a is, for example, a cannonball-shaped member formed of metal. The upper end of the contact portion 2123a has a spherical shape, for example, but may also have other shapes such as a flat surface. In a state in which the lighting fixture connector 2100 is not attached to the suspended ceiling lamp socket main body 2200, the contact portion 2123a protrudes toward the suspended ceiling lamp socket main body 2200 side than the first surface 111a. In addition, when the lighting fixture connector 2100 is not attached to the suspended ceiling lamp holder body 2200, the height of the contact portion 2123a based on the first surface 111a is lower than the first terminal 121 and the second terminal 122. But it can also be higher.

The elastic member 2123b is specifically a coil spring, but may be other springs or the like. The upper end of the elastic member 2123b is connected to the contact portion 2123a; the lower end of the elastic member 2123b is connected to the end of the third terminal 2123 (not shown) in the connector insertion port 150. The elastic member 2123b is located inside the housing 110.

On the other hand, as shown in FIGS. 14 and 15, the suspended ceiling lamp holder main body 2200 includes a fourth terminal 2220 at the center of the surface of the main body 210 facing the lighting fixture connector 2100. A part of the fourth terminal 2220 is exposed to the outside from the main body of the suspended ceiling lamp holder main body 2200, and the other part is grounded by wiring or the like inside the suspended ceiling lamp holder main body 2200. The planar shape of the fourth terminal 2220 is, for example, a circle, but it may also be other shapes such as a rectangle.

In addition, the fourth terminal 2220 may have a recessed portion corresponding to the shape of the contact portion 2123a. These recesses can be used to align the third terminal 2123 with the fourth terminal 2220.

The third terminal 2123 elastically deforms the elastic member 2123b by pushing from above. The elastic member 2123b, specifically, shrinks. Therefore, as shown in FIG. 15, in the state where the lighting fixture connector 2100 is mounted to the suspended ceiling lamp holder body 2200, the third terminal 2123 is pressed by the fourth terminal 2220, and the elastic member 2123b is elastically deformed. , The contact portion 2123a is in contact with the fourth terminal 2220.

In this way, the third terminal 2123 of the connector 2100 for lighting equipment may be composed of a plurality of members.

[Modification 3] In addition, the first surface 111a of the lighting fixture connector 100 is provided with three terminals: the first terminal 121, the second terminal 122, and the third terminal 123, but other terminals may be further provided. Fig. 16 is a perspective view of the appearance of the connector for lighting equipment of Modification 3 as viewed from above.

As shown in FIG. 16, the connector 3100 for lighting equipment includes a fifth terminal 124 and a fifth terminal 125 provided on the first surface 111 a of the housing 110.

The fifth terminal 124 and the fifth terminal 125 are terminals for signal transmission that transmit signals from the suspended ceiling lamp holder body 3200 to the appliance body 310. The fifth terminal 124 and the fifth terminal 125 are, for example, a pair of terminals for dimming signal transmission for dimming of the lighting device 300. The fifth terminal 124 and the fifth terminal 125 can also be a pair of terminals used to transmit the color adjustment signal of the lighting appliance 300, or can be used to transmit the control signal of the light control including dimming and color adjustment. Use one pair of terminals. In addition, the fifth terminal 124 and the fifth terminal 125 can also be used for signal transmission from the appliance body 310 to the suspended ceiling lamp holder body 3200.

In addition, the connector for lighting equipment 3100 has a pair of fifth terminals 124 and a pair of fifth terminals 125 to allow differential transmission of signals, but at least one fifth terminal is sufficient. By making the potential of the third terminal 123 a reference potential or the like, a signal can be transmitted by one fifth terminal.

The fifth terminal 124 is electrically connected to the terminal for signal transmission in the main body 3200 of the suspended ceiling lamp holder by penetrating the through hole 214a. The fifth terminal 125 is electrically connected to the terminal for signal transmission in the main body 3200 of the suspended ceiling lamp holder by penetrating the through hole 214b.

The upper end of the fifth terminal 124 is not bent, and is not used for mechanical connection of the connector 3100 for lighting equipment. However, the upper end portion of the fifth terminal 124 may be bent and used for mechanical connection of the connector 3100 for lighting equipment.

The connector 3100 for these lighting appliances can not only transmit power but also transmit signals to the appliance body 310. In addition, in Modification 3, the third terminal 123 is used as the grounding terminal, but instead of the third terminal 123, the third terminal 1123 or the third terminal 2123 may be used.

[Effects etc.] As described above, the connector 100 for lighting equipment is a connector for lighting equipment for connecting the main body 200 of the suspended ceiling lamp holder to the main body 310 of the lighting equipment 300. The connector 100 for lighting equipment includes a housing 110 having a first surface 111a facing the suspended ceiling lamp holder body 200; a first terminal 121 and a second terminal 122 for power supply provided on the first surface 111a; and The third terminal 123 for grounding is provided at the center of the first surface 111a. The connector 100 for lighting equipment is installed to the suspended ceiling lamp socket main body 200 by allowing the first terminal 121 and the second terminal 122 to respectively penetrate through holes provided in the suspended ceiling lamp socket main body 200. In a state where the lighting fixture connector 100 is attached to the suspended ceiling lamp socket main body 200, the third terminal 123 and the fourth terminal 220 provided on the suspended ceiling lamp socket main body 200 are in contact with each other in a deformed state. The first surface 111a is an example of the facing surface.

As a result, the third terminal 123 for grounding is provided in the connector 100 for lighting equipment, so the safety of the lighting equipment 300 can be improved.

In addition, for example, in a state in which the lighting fixture connector 100 is attached to the suspended ceiling lamp socket main body 200, the fourth terminal 220 contacts the third terminal 123 in an elastically deformed state.

In this way, the structure of elastically deforming the fourth terminal 220 simplifies the structure of the connector 100 for lighting equipment.

In addition, for example, in a state in which the lighting fixture connector 100 is attached to the suspended ceiling lamp holder body 200, the fourth terminal 220 is elastically deformed by being stretched by the third terminal 123, and is in an elastically deformed state with the third terminal 123 contacts.

These fourth terminals 220 can temporarily hold the third terminals 123 by elasticity. If the connector 100 for lighting equipment is temporarily held by the fourth terminal 220, the user simply attaches the connector 100 for lighting equipment to the suspended ceiling lamp socket main body 200.

In addition, for example, the third terminal 123 includes a base portion 123c and a large diameter portion 123d having a larger diameter than the base portion 123c. When the lighting fixture connector 100 is attached to the suspended ceiling lamp socket main body 200, the fourth terminal 220 is elastically deformed by being stretched by the large diameter portion 123d, and contacts the large diameter portion 123d in an elastically deformed state.

These fourth terminals 220 can temporarily hold the large diameter portion 123d of the third terminal 123. If the connector 100 for lighting equipment is temporarily held by the fourth terminal 220, the user simply attaches the connector 100 for lighting equipment to the suspended ceiling lamp socket main body 200.

In addition, in Modification 1, the third terminal 1123 contacts the fourth terminal 1220 in an elastically deformed state in a state in which the lighting fixture connector 1100 is attached to the suspended ceiling lamp socket main body 1200. The same is true in Modification 2.

In this way, the structure of the third terminal 1123 provided in the lighting fixture connector 1100 is elastically deformed, so that the structure of the suspended ceiling lamp holder body 1200 can be simplified. For example, the miniaturization (thinness) of the main body 1200 of the suspended ceiling lamp holder becomes simple.

In addition, in Modification 1, the third terminal 1123 has a plate shape that is bent so as to protrude toward the main body 1200 of the suspended ceiling lamp socket.

According to the third terminal 1123 with a relatively simple structure, the structure of the connector 1100 for lighting equipment can be simplified.

In addition, in Modification 2, the third terminal 2123 includes: a contact portion 2123a that is in contact with the fourth terminal 2220; and an elastic member 2123b that biases the contact portion 2123a to the suspended ceiling lamp holder body 2200. In a state where the lighting fixture connector 2100 is attached to the suspended ceiling lamp socket main body 2200, the third terminal 2123 brings the contact portion 2123a into contact with the fourth terminal 2220 in a state where the elastic member 2123b is elastically deformed.

These third terminals 2123 can make contact with the fourth terminals 2220 more reliably.

In addition, in a state where the lighting fixture connector 100 is not installed in the suspended ceiling lamp socket main body 200, the third terminal 123 protrudes to the suspended ceiling lamp socket main body 200 side than the first terminal 121 and the second terminal 122.

Thereby, when the luminaire connector 100 is installed on the suspended ceiling lamp holder body 200, the third terminal 123 is easier to be electrically connected to the terminal before the first terminal 121 and the second terminal 122. Therefore, it is possible to improve the safety when attaching the joint 100 for lighting equipment to the suspended ceiling lamp socket main body 200. In addition, the user can use the third terminal 123 to align the connector 100 for lighting equipment with the main body 200 of the suspended ceiling lamp holder.

In addition, in Modification 3, the connector 3100 for lighting equipment further includes a fifth terminal 124 for signal transmission, which is provided on the first surface 111a.

The connector 3100 for these lighting appliances can transmit signals from the main body 3200 of the suspended ceiling lamp holder to the main body 310 of the appliance.

In addition, for example, the fifth terminal 124 is a terminal for dimming signal transmission used for dimming of the lighting device 300.

The connector 3100 for these lighting fixtures can transmit the dimming signal from the main body 3200 of the suspended ceiling lamp holder to the main body 310 of the fixture.

In addition, the lighting fixture 300 includes a connector 100 for lighting fixtures and a fixture body 310.

These lighting fixtures 300 are provided with the third terminal 123 for grounding in the lighting fixture connector 100, so the safety is improved.
