In the following embodiments, the so-called "under a plan view" means viewing from the Z-axis direction.

(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 tray 200 installed on a structure such as a ceiling.

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, which have a plurality of LEDs inside each, 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 plate 200 to 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 joint 100 for lighting equipment is rotated in the installation direction with respect to the ceiling plate 200, thereby In order to mount the joint 100 for lighting equipment to the ceiling 200. In other words, the connector 100 for lighting equipment is mechanically and electrically connected to the ceiling plate 200.

Furthermore, 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 pressed toward the ceiling 200 side 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 joint 100 for lighting equipment relative to the ceiling 200 is restricted. In other words, the rotation of the joint 100 for lighting equipment relative to the ceiling 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 are due to the elastic member contained in the housing 110 (It is not shown in FIGS. 1 to 3), and it is pressed from the inside of the housing 110 toward 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 will abut 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 will resist the elastic member The pressing force 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 relationship between 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 is 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 given by the elastic member 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. With this, the mechanical and electrical installation of the luminaire 300 to the ceiling 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 panel 200 while pressing the unlock button 140, the lighting fixture connector 100 can be removed from the ceiling panel 200.

So far, the pen protruding from the first surface 111a of the housing 110 has a third terminal 123 in addition to the first terminal 121 and the second terminal 122. The third terminal 123 is a ground terminal and penetrates the insertion hole 213 of the ceiling tray 200. In this way, when the connector 100 for lighting equipment has three terminals, the arrangement of the three terminals in the housing 110 still has room for discussion. In the connector 100 for lighting equipment, three terminals are arranged so as to suppress the enlargement of the housing 110. This terminal configuration will be described in detail later.

[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. Also, in Figures 4 and 5, for the fixing member and the member All screws are omitted from the illustration.

The connector 100 for lighting equipment includes a housing 110, a first terminal 121, a second terminal 122, a third 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 elastic member 170, and the locking part 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 111 a facing the ceiling 200 and a second surface 112 a opposite to the first surface 111 a. 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.

The main body 111 is provided with terminal insertion holes 111a1, terminal insertion holes 111a2, and terminal insertion holes 111a3 at a portion of the main body 111 facing the ceiling tray 200. The end 121a of one side of the first terminal 121 protrudes from the terminal insertion hole 111a1, the end 122a of one side of the second terminal 122 protrudes from the terminal insertion hole 111a2, and the end 123a of one side of the third 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 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 port 150 is a portion that extends cylindrically from the inner surface of the portion of the main body 111 facing the ceiling 200 toward the second surface 112a. The connector insertion port 150 is exposed to the outside from the housing 110 through an opening 112b provided in the center of the outer cover 112, and is detachably connected to the connector 330 of the appliance main body 310. 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 resin plate-shaped member that covers the bottom surface side of the main body 111. The cover 112 constitutes the bottom surface (connecting surface) of the housing 110, and in the center of the 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 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 with screws. The end 121a of one side of the first terminal 121 protrudes from the terminal insertion hole 111a1 provided in the housing 110. The other end 121b of the first terminal 121 is disposed in the connector insertion opening 150. Similarly, the end 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 other end 122b of the second terminal 122 is disposed in the connector insertion opening 150. The end 123 a on one side of the third terminal 123 protrudes from the terminal insertion hole 111 a 3 provided in the housing 110, and the end 123 b on the other side of the third terminal 123 is disposed in the connector insertion opening 150.

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

Furthermore, the end 121a on one side of the first terminal 121 and the end 122a on one side of the second terminal 122 are respectively bent into an L-shape. If the end 121a of one side of the first terminal 121 penetrates the insertion hole 211, and the end 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 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 200.

On the other hand, the third terminal 123 is a ground terminal. By inserting the end 123 a of one side of the third terminal 123 into the insertion hole 213, the third terminal 123 is electrically connected to the ground terminal in the ceiling tray 200. Unlike the first terminal 121 and the second terminal 122, the end 123a of one side of the third terminal 123 is not bent, and the third terminal 123 is not used for mechanical connection of the connector 100 for lighting equipment. However, the end 123a of one side of the third terminal 123 may also be bent so that the third terminal 123 is used for mechanical connection of the connector 100 for lighting equipment.

The end 121b on the other side of the first terminal 121, the end 122b on the other side of the second terminal 122, and the end 123b on the other side of the third terminal 123 are connected between the connector 330 and the connector insertion port 150 In the state, it is connected to the metal terminal in the connector 330.

In addition, it may also be configured that the length of the portion protruding from the first surface 111a of the end portion 123a of one side of the third terminal 123 is greater than that of the end portion 121a of one side of the first terminal 121 from the first surface 111a. The length of the protruding part and the length of the part protruding from the first surface 111a among the end portions 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 mounted to the ceiling 200, the third terminal 123, which is a ground terminal, is easily connected to the terminals in the ceiling 200 before the first terminal 121 and the second terminal 122. Sexual connection. Therefore, the safety at the time of attaching the joint 100 for lighting equipment to the ceiling 200 can be improved.

Similarly, the end 123b on the other side of the third terminal 123 may be more toward the second surface 112a than the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122 protrude.

Thereby, when the appliance main body 310 and the lighting appliance connector 100 are electrically connected, the third terminal 123, which is a ground terminal, can easily be electrically connected to the appliance main body 310 earlier than the first terminal 121 and the second terminal 122. connect. 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 main body 310 to the lighting fixture connector 100.

The first locking member 131 is pressed from the inner side of the housing 110 to the outside by the elastic member 170, and protrudes from the first opening 111c1 toward the outer side of the housing 110. The second locking member 132 is pressed from the inner side of the housing 110 toward the outside by the elastic member 170 and protrudes toward the outer side of the housing 110 from the second opening 111c2. The elastic member 170 is specifically a torsion spring, but other elastic members may also be used.

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

The first operating lever 161 and the second operating lever 162 are resin-made members for detaching and operating the fixture main body 310 from the lighting fixture connector 100.

The first operating lever 161 is a member for moving 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 protrudes from the opening 112b provided in the outer cover 112, and is operated by the user. The opening 112b is an example of the third 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 recess 131a of the first locking member 131, whereby the first operating lever 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 161 a from the central portion of the housing 110 toward the outside, the first locking member 131 resists the elastic force of the elastic member 170 and moves toward the inside of the housing 110.

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 162a protrudes from the opening 112b provided in the outer cover 112, and is operated by the user. The opening 112b is an example of the fourth 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 162 a from the central part of the housing 110 toward the outside of the housing 110, the second locking member 132 resists the elastic force of the elastic member 170 and moves toward the inside of the housing 110.

In this way, the user pulls the first operated portion 161a and the second operated portion 162a outwards from the central part of the housing 110, so that the first locking member 131 and the second locking member 132 face the housing. It moves inside 110, and the apparatus main body 310 can be detached from the connector 100 for lighting apparatuses.

The locking part 180 is a member for restricting the movement of the lighting fixture connector 100 relative to the ceiling 200 in order to maintain the state where the lighting fixture connector 100 is normally mounted on the ceiling 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 against the bottom in the spring hole 182 and the other end abutting against 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 , And the protrusion 181 will protrude from the first surface 111 a of the housing 110 due to the urging force (elastic force) of the coil spring 190 and penetrate the insertion hole 212. In this state, the rotation of the lighting fixture connector 100 relative to the ceiling 200 is restricted. That is, the rotation of the joint 100 for lighting equipment with respect to the ceiling 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 plate 200 to restrict the lighting fixture connector 100 relative to the suction Movement of the top plate 200.

The unlocking button 140 is a button for pulling out the protrusion 181 from the insertion hole 212 by being pressed down on the side wall of the housing 110. The unlock button 140 is a resin member located on the outer side of the housing 110 with a part of it passing through a notch provided on 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. Thereby, the restriction on the rotation of the joint 100 for lighting equipment with respect to the ceiling 200 is released. The user can detach the joint 100 for lighting equipment from the ceiling 200 by rotating the joint 100 for lighting equipment with respect to the ceiling 200 while pressing the unlock button 140.

[Terminal configuration] Next, the arrangement of the first terminal 121, the second terminal 122, and the third terminal 123 when viewing the lighting fixture connector 100 from the second surface 112a side will be described. Fig. 6 is a diagram of the lighting fixture connector 100 viewed from the second surface 112a side. In addition, in FIG. 6, the housing 110 and the connector insertion opening 150 are shown in dashed lines.

As described above, the other end 121 b of the first terminal 121, the other end 122 b of the second terminal 122, and the other end 123 b of the third terminal 123 are located in the connector insertion opening 150. The end 121b on the other side of the first terminal 121, the end 122b on the other side of the second terminal 122, and the end 123b on the other side of the third terminal 123 can be compared to other terminals or conductive members. To ensure insulation, each needs to be arranged at the required predetermined interval. Suppose, the first position P1 of the other end 121b of the first terminal 121, the second position P2 of the other end 122b of the second terminal 122, and the second position P2 of the other end 123b of the third terminal 123 The three positions P3 are all arranged on a straight line along the Y-axis direction, and sometimes the size of the housing 110 in the Y-axis direction may increase. In addition, the position referred to here (specifically, the first position P1, the second position P2, and the third position P3) means, for example, the center of the end of the other side of the terminal viewed from the second surface 112a side Position (or the coordinates of the center position).

In view of this, in the lighting fixture connector 100, the first position P1 of the other end 121b of the first terminal 121, the second position P2 of the other end 122b of the second terminal 122, and the third terminal 123 The third position P3 of the end 123b on the other side is not arranged on a straight line. The first position P1, the second position P2, and the third position P3 constitute three vertices of the triangle.

Thereby, compared with the case where the first position P1, the second position P2, and the third position P3 are arranged on a straight line along a certain direction, it is easier to reduce the size of the housing 110 in the one direction.

Furthermore, the triangle with the first position P1, the second position P2, and the third position P3 as the three vertices can be any triangle; however, in the joint 100 for lighting equipment, this triangle is an isosceles triangle. In other words, the first position P1, the second position P2, and the third position P3 are arranged to form three vertices of an isosceles triangle. In other words, the third position P3 is located on the vertical bisector connecting the first position P1 and the second position P2.

Thereby, the distance between the other end 121b of the first terminal 121 and the other end 123b of the third terminal 123 is equal to the difference between the other end 122b of the second terminal 122 and the third terminal 123 The interval between the ends 123b of one side. When the third terminal 123 is a ground terminal, it is easy to make the distance between the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122 equal to the ground terminal.

Furthermore, in the lighting fixture connector 100, the first position P1 and the second position P2 are located on a straight line L passing through the center position C of the housing 110; on the negative side of the X-axis than the straight line L, it is arranged Unlock button 140; and the end 123b on the other side of the third terminal 123 is positioned on the positive side of the X axis than the straight line L. That is, the straight line L connecting the first position P1 and the second position P2 passes between the unlock button 140 and the third position P3. In addition, the center position C of the housing 110 is a position through which the rotating shaft passes when the joint 100 for lighting equipment is mounted on the ceiling 200.

As a result, since the end 123b of the other side of the third terminal 123 and the unlock button 140 are not arranged in one of the two regions divided by the straight line L, even if the size of the housing 110 is reduced It also makes it difficult for the end 123b of the other side of the third terminal 123 and the unlock button 140 to interfere with each other. In other words, it is easier to miniaturize the size of the housing 110.

Furthermore, in the lighting fixture connector 100, the first locking member 131 and the second locking member 132 are arranged side by side in the Y-axis direction, and the other end 121b of the first terminal 121 and the second terminal The other end 122b of the 122 is located between the first locking member 131 and the second locking member 132. In other words, the Y-axis direction is the arrangement direction of the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122.

In this way, when the first locking member 131 and the second locking member 132 are arranged, if the first position P1, the second position P2, and the third position P3 are arranged on a straight line along the Y-axis direction Above, the three terminals and the first locking member 131 and the second locking member 132 easily interfere with each other, which makes it more difficult to reduce the size of the housing 110 in the Y-axis direction. Therefore, when the first locking member 131 and the second locking member 132 are arranged as described above, the first position P1, the second position P2, and the third position P3 are arranged to form three vertices of the triangle. Good results.

Furthermore, in the lighting fixture connector 100, the first operating lever 161 (specifically, the first operated portion 161a) and the second operating lever 162 (specifically, the second operated portion 162a) are tied to They are arranged side by side in the Y-axis direction. The other end 121b of the first terminal 121 and the other end 122b of the second terminal 122 are located between the first operated portion 161a and the second operated portion 162a.

In this way, when the first operated portion 161a and the second operated portion 162a are arranged, if the first position P1, the second position P2, and the third position P3 are arranged on a straight line along the Y-axis direction Above, the three terminals and the first operated portion 161a and the second operated portion 162a are likely to interfere with each other, which makes the miniaturization of the housing 110 in the Y-axis direction more difficult. Therefore, when the first operated portion 161a and the second operated portion 162a are arranged as described above, the first position P1, the second position P2, and the third position P3 are arranged to form three vertices of the triangle. Good results.

However, as described above, the surroundings of 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 cannot be arranged. A conductive member. For example, if viewed from the side of the second surface 112a, starting from the center of each of the first position P1, the second position P2, and the third position P3, a circular area within the radius r cannot be arranged with conductivity The component. In this case, as shown in FIG. 7, if the first position P1, the second position P2, and the third position P3 are arranged on a straight line with an interval r, the area A surrounded by a thick line is The area where conductive components cannot be arranged. FIG. 7 shows a diagram of a region where conductive members cannot be arranged when the first position P1, the second position P2, and the third position P3 are arranged on a straight line.

On the other hand, when the first position P1, the second position P2, and the third position P3 constitute the three vertices of an isosceles triangle, the area B enclosed by the thick line in FIG. 8 cannot be arranged. The area of conductive components. FIG. 8 shows a diagram of a region where conductive members cannot be arranged when the first position P1, the second position P2, and the third position P3 constitute the three vertices of an isosceles triangle.

Here, in Figure 8, if the length r1 of the vertical line from the vertex corresponding to the third position P3 down to the bottom side satisfies the condition of r1≦1.13r, the area of area B in Figure 8 can be set to Area 7 is less than the area of A. That is to say, if the length of the base of the isosceles triangle formed by the first position P1, the second position P2, and the third position P3 is set to 1, then in the isosceles triangle, from corresponding to the third position P3 The length of the vertical line from the apex down to the bottom side should be less than 1.13. Thereby, even if the housing 110 is miniaturized, it is easy to arrange a conductive member. In other words, the miniaturization of the housing 110 can be made easier. Also, the minimum value of r1 is, for example, (√3/2)×r.

Furthermore, the first locking member 131 and the second locking member 132 are symmetrical in shape, size, arrangement, etc. In contrast, the shape and size of the first operating rod 161 and the second operating rod 162 are slightly different. Specifically, the shape and size of the first connecting portion 161b and the second connecting portion 162b are different.

The first connecting portion 161b and the second connecting portion 162b are arranged side by side in a direction intersecting the Y-axis direction (specifically, the X-axis direction orthogonal to the Y-axis direction). When viewed from the second surface 112a side, the end 121b on the other side of the first terminal 121, the end 122b on the other side of the second terminal 122, and the end 123b on the other side of the third terminal 123 are positioned Between the first connecting portion 161b and the second connecting portion 162b. The distance from the straight line L connecting the first position P1 and the second position P2 to the second connecting portion 162b is greater than the distance from the straight line L to the first connecting portion 161b. In addition, the "distance from the straight line L to the second connecting portion 162b" means, for example, the distance from the center position C in the X-axis direction to the second connecting portion 162b. The "distance from the straight line L to the first connecting portion 161b" is the same.

Thereby, since the space between the straight line L and the second connecting portion 162b is larger than the space between the straight line L and the first connecting portion 161b, it is easier to arrange the end 123b on the other side of the third terminal 123.

Above, the arrangement of the first terminal 121, the second terminal 122, and the third terminal 123 when viewed from the second surface 112a side has been described. Also, the same is true when viewed from the side of the first surface 111a, the position of the end 121a of one side of the first terminal 121, the position of the end 122a of one side of the second terminal 122, and the end of one side of the third terminal 123 The position of the portion 123a is the three vertices constituting the triangle. In this case, the position of the end 121a on one side of the first terminal 121, the position of the end 122a on one side of the second terminal 122, and the position of the end 123a on one side of the third terminal 123 may also be configured, etc. The 3 vertices of the waist triangle.

[Effects etc.] As described above, the lighting fixture connector 100 is a lighting fixture connector for connecting the ceiling 200 and the fixture 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 200 and a second surface 112a opposite to the first surface 111a), and a first terminal 121 and a second The terminal 122 and the third terminal 123. The ends of the first terminal 121, the second terminal 122, and the third terminal 123 respectively protrude from the terminal insertion hole provided on the first surface 111a of the housing 110, and the other end is located on the The connector on the side of the second surface 112 a of the housing 110 is inserted into the opening 150. The connector insertion port 150 is an example of a recessed portion. When viewed from the second surface 112a side, the first position P1 of the other end 121b of the first terminal 121, the second position P2 of the other end 122b of the second terminal 122, and the third terminal 123 The third position P3 of the end 123b on the other side constitutes the three vertices of the triangle.

Thereby, compared to the case where the first position P1, the second position P2, and the third position P3 are arranged on a straight line, it is easier to reduce the size of the housing 110. In other words, it is possible to realize the joint 100 for lighting equipment that is easy to be downsized.

Furthermore, for example, the first position P1, the second position P2, and the third position P3 constitute three vertices of an isosceles triangle. An isosceles triangle has the inner angle corresponding to the apex of the third position P3 as the apex angle.

Thereby, it is easy to make the distance between the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122 to the third terminal 123 equal.

Furthermore, for example, if the length of the base of the isosceles triangle is 1, the length of the perpendicular from the vertex corresponding to the third position P3 down to the base of the isosceles triangle is 1.13 or less.

Thereby, even if the housing 110 is miniaturized, it is easy to arrange a conductive member. In other words, the miniaturization of the housing 110 can be made easier.

Furthermore, for example, the joint 100 for lighting equipment further includes a protrusion 181 that 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 200, In this way, the movement of the lighting fixture connector 100 relative to the ceiling 200 is restricted; and the unlock button 140 is provided on the side wall of the housing 110, and the protrusion 181 is pulled out from the insertion hole 212 with a downward pressure. When viewed from the second surface 112a side, the straight line L connecting the first position P1 and the second position P2 passes between the unlock button 140 and the third position P3.

As a result, since the end 123b of the other side of the third terminal 123 and the unlock button 140 are not arranged in one of the two regions divided by the straight line L, even if the size of the housing 110 is reduced It also makes it difficult for the end 123b of the other side of the third terminal 123 and the unlock button 140 to interfere with each other. In other words, it is easier to miniaturize the size of the housing 110.

Furthermore, for example, the lighting fixture connector 100 further includes a first locking member 131 that protrudes from the first opening 111c1 provided in the side wall of the housing 110 and is used to lock the fixture body 310 to the lighting fixture. The connector 100; and the second locking member 132, which protrudes from the second opening 111c2 provided in the side wall of the housing 110, and is used to lock the device body 310 to the connector 100 for lighting equipment. The first locking member 131 and the second locking member 132 are arranged side by side in the arrangement direction of the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122. The arrangement direction moves. The arrangement direction is the Y direction in the above embodiment. When viewed from the side of the second surface 112a, the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122 are positioned between the first locking member 131 and the second locking member 131 Between members 132.

In this way, when the first locking member 131 and the second locking member 132 are arranged, if the first position P1, the second position P2, and the third position P3 are arranged on a straight line along the above-mentioned arrangement direction Above, the miniaturization of the housing 110 in the above-mentioned arrangement direction will be more difficult. Therefore, when the first locking member 131 and the second locking member 132 are arranged as described above, the first position P1, the second position P2, and the third position P3 are arranged to form three vertices of the triangle. Good results.

Furthermore, for example, the lighting fixture connector 100 further includes a first operating lever 161 having a first operated portion 161a protruding from an opening 112b provided on the second surface 112a side of the housing 110, and is used So that the first locking member 131 moves along the above-mentioned arrangement direction; and the second operating lever 162 has a second operated portion 162a protruding from the opening 112b provided on the second surface 112a side of the housing 110, and is used This allows the second locking member 132 to move along the above-mentioned arrangement direction. The opening 112b is an example of the third opening and the fourth opening. The first operated portion 161a and the second operated portion 162a are arranged side by side in the above arrangement direction; when viewed from the second surface 112a side, the end 121b on the other side of the first terminal 121 and the second terminal The other end 122b of the 122 is located between the first operated portion 161a and the second operated portion 162a.

In this way, when the first operated portion 161a and the second operated portion 162a are arranged, if the first position P1, the second position P2, and the third position P3 are arranged on a straight line along the above-mentioned arrangement direction Above, the miniaturization of the housing 110 in the above arrangement direction is more difficult. Therefore, when the first operated portion 161a and the second operated portion 162a are arranged as described above, the first position P1, the second position P2, and the third position P3 are arranged to form three vertices of the triangle. Good results.

Furthermore, for example, the first operating lever 161 has a first connecting portion 161 b to connect the first operated portion 161 a and the first locking member 131. The second operating lever 162 has a second connecting portion 162 b to connect the second operated portion 162 a and the second locking member 132. The first connecting portion 161b and the second connecting portion 162b are arranged side by side in a direction crossing the above-mentioned arrangement direction. When viewed from the second surface 112a side, the end 121b on the other side of the first terminal 121, the end 122b on the other side of the second terminal 122, and the end 123b on the other side of the third terminal 123 are positioned Between the first connecting portion 161b and the second connecting portion 162b. The distance from the straight line L connecting the first position P1 and the second position P2 to the second connecting portion 162b is greater than the distance from the straight line L to the first connecting portion 161b.

Thereby, it is easier to arrange the end 123b of the other side of the third terminal 123 in the space between the straight line L and the second connecting portion 162b.

Furthermore, for example, the first terminal 121 and the second terminal 122 are a pair of terminals for the lighting fixture 300 to receive power from the ceiling plate 200; the third terminal 123 is a ground terminal.

In this way, by providing the connector 100 for lighting equipment with a ground terminal, the safety of the connector 100 for lighting equipment can be improved.

Furthermore, for example, the end 123b on the other side of the third terminal 123 is more toward the second surface than the end 121b on the other side of the first terminal 121 and the end 122b on the other side of the second terminal 122 Side protruding.

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

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

With this, it is possible to realize a lighting fixture 300 that can easily reduce the size of the lighting fixture connector 100.

For example, in the above-mentioned embodiment, the connector for lighting equipment is equipped with the 1st locking member and the 2nd locking member so that the equipment main body of a lighting tool can be locked with the connector for lighting equipment. However, the joint for lighting equipment does not necessarily have the first locking member and the second locking member. For example, a spiral groove may be provided on the inner peripheral surface of the mounting hole of the fixture body and the outer peripheral surface of the housing side wall of the lighting fixture connector, respectively, and the fixture body and the lighting fixture connector may be screwed together.
