(Implementation form)
Hereinafter, a lighting fixture according to an embodiment will be described. Fig. 1 is an exploded perspective view of a lighting fixture according to an embodiment. FIG. 2 is an enlarged view of a region II in FIG. 1, and is an external perspective view of the joint for a lighting fixture of the embodiment viewed from below. Fig. 3 is an external perspective view of the joint for a lighting fixture according to the embodiment as viewed from above. Furthermore, in Figs. 1 to 3, there is also shown a ceiling pad 200 provided on a structure such as a ceiling.

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

The appliance main 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 a central portion of the appliance body 310.

The light source unit 320 a and the light source unit 320 b are light sources, each of which has a plurality of LEDs and emits light toward, for example, the lamp cover 350 (below).

The connector 330 is a connector connected to the joint 100 for a lighting fixture. By connecting the connector 330 to the lighting fixture connector 100, the lighting fixture connector 100 is electrically connected to the fixture body 310.

The cover 350 is a light-transmitting optical member, and the shape of the cover 350 in a plan view is a rounded rectangle. The lamp cover 350 is attached to the apparatus main body 310 so that the bottom surface of the apparatus main body 310 may be covered. The shape of the lamp cover 350 in a plan view may be circular.

The lighting fixture joint 100 is a joint for connecting the ceiling plate 200 and the fixture body 310 of the lighting fixture 300. The joint 100 for a lighting fixture 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 device connector 100 is rotated in the mounting direction with respect to the ceiling plate 200, whereby The joint 100 for lighting fixtures is attached to the ceiling plate 200. In other words, the joint 100 for a lighting fixture is mechanically and electrically connected to the ceiling plate 200.

In addition, when the connector 100 for a lighting fixture is rotated 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 projection 181 is pushed toward the ceiling plate 200 side. The position overlaps the position of the insertion hole 212, and the protrusion 181 protrudes from the first surface 111a of the housing 110 and penetrates into the insertion hole 212. In this state, the rotation of the joint 100 for lighting fixtures with respect to the ceiling plate 200 is restricted. That is, the rotation of the joint 100 for lighting fixtures with respect to the ceiling plate 200 is locked.

In addition, 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 accommodated in the housing 110. (Not shown in FIG. 1 to FIG. 3), but is pushed from the inside of the housing 110 toward the outside.

The user pushes up the fixture body 310 so that the housing 110 of the lighting fixture joint 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 elastic member. Is pushed toward the inside of the housing 110 by the pressing force of.

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 edges 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 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 appliance 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 opening 150 provided on the bottom surface side of the housing 110 of the joint 100 for lighting fixtures, and attaches a cover 340 covering the mounting hole 360 and a lamp cover 350 from the bottom surface side. Thereby, the operation of mechanically and electrically mounting the lighting fixture 300 to the ceiling plate 200 is completed.

The method of removing 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 operation lever 161 and the second operation lever 162 from the central portion of the housing 110 to the outside, respectively. In this way, the first locking member 131 and the second locking member 132 move toward the inside of the housing 110. Thereby, the user can remove the fixture main body 310 from the lighting fixture joint 100.

When the user rotates the lighting fixture connector 100 in the removal direction with respect to the ceiling plate 200 while holding down the unlock button 140, the lighting fixture connector 100 can be removed from the ceiling plate 200.

At this point, in addition to the first terminal 121 and the second terminal 122, the third terminal 123 protrudes from the first surface 111a of the housing 110. The third terminal 123 is a ground terminal and penetrates the insertion hole 213 of the ceiling plate 200. As such, when the connector 100 for a lighting fixture has three terminals, there is still room for discussion on the arrangement of the three terminals in the housing 110. In the joint 100 for lighting fixtures, three terminals are arranged so as to suppress an increase in size of the housing 110. This terminal arrangement will be described in detail later.

[Structure of joint for lighting equipment]
Next, the structure of the joint 100 for lighting fixtures 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 joint 100 for a lighting fixture viewed from above. FIG. 5 is an exploded perspective view of the joint 100 for a lighting fixture viewed from below. In addition, in FIGS. 4 and 5, illustrations of the fixing members and the screws of the members are omitted.

The connector 100 for a lighting fixture 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 operation lever 162, the elastic member 170, and the lock portion 180.

The housing 110 is a substantially flat cylindrical member that houses each constituent element included in the joint 100 for a lighting fixture. The housing 110 has a first surface 111 a facing the ceiling plate 200 and a second surface 112 a opposite to the first surface 111 a. The casing 110 specifically includes a main body portion 111 on the first surface 111a side and a cover 112 on the second surface 112a side.

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

A terminal insertion hole 111a1, a terminal insertion hole 111a2, and a terminal insertion hole 111a3 are provided in a portion of the main body portion 111 facing the ceiling plate 200. An end portion 121a of one side of the first terminal 121 protrudes from the terminal insertion hole 111a1, an end portion 122a of one side of the second terminal 122 protrudes from the terminal insertion hole 111a2, and an end portion 123a of one side of the third terminal 123 protrudes from the terminal insertion hole 111a3. .

Further, an opening 111b is provided in a portion of the main body portion 111 facing the ceiling plate 200. A projection 181 having a lock portion 180 projects from the opening 111b.

A first opening 111c1 and a second opening 111c2 are provided in a side wall portion of the main body portion 111. The first locking member 131 protrudes from the first opening 111 c 1 toward the outer side of the main body portion 111. The second locking member 132 protrudes from the second opening 111 c 2 toward the outer side of the main body portion 111.

A connector insertion port 150 is provided inside the main body portion 111. The connector insertion opening 150 is a portion extending from the inner surface of the main body portion 111 facing the ceiling plate 200 toward the second surface 112a and extending in a cylindrical shape. The connector insertion port 150 is exposed from the housing 110 to the outside through an opening 112b provided in the center of the cover 112, and is connected to the connector 330 of the appliance main body 310 in a detachable manner. The shape of the connector insertion opening 150 in a plan view is substantially a T-shape, and the connector 330 also has a shape corresponding thereto. The connector insertion opening 150 is an example of a recessed portion provided on the second surface 112 a side of the housing 110.

The cover 112 is a resin plate-like member that covers the bottom surface side of the main body portion 111. The cover 112 constitutes the bottom surface (connecting surface) of the housing 110, and an opening 112 b is provided in the center of the cover 112. The connector insertion port 150, the first operated portion 161a of the first operation lever 161, and the second operated portion 162a of the second operation lever 162 are exposed from the opening 112b to the outside.

The first terminal 121, the second terminal 122, and the third terminal 123 are plate 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 portion 111 with screws. An end portion 121 a of one side of the first terminal 121 protrudes from a terminal insertion hole 111 a 1 provided in the housing 110. The other end 121 b of the first terminal 121 is disposed in the connector insertion opening 150. Similarly, an end portion 122 a of one side of the second terminal 122 protrudes from a terminal insertion hole 111 a 2 provided in the housing 110. The other end 122 b of the second terminal 122 is disposed in the connector insertion opening 150. An end portion 123a on one side of the third terminal 123 protrudes from a terminal insertion hole 111a3 provided in the housing 110, and an end portion 123b on the other side of the third terminal 123 is disposed in the connector insertion port 150.

The first terminal 121 and the second terminal 122 are a pair of terminals used by the lighting fixture 300 to receive power supply from the ceiling plate 200. The first terminal 121 and the second terminal 122 are made by inserting the end portion 121a of one side of the first terminal 121 into the insertion hole 211 and the end portion 122a of one side of the second terminal 122 into the insertion hole 212. A pair of power supply terminals in the ceiling board 200 are electrically connected. The luminaire 300 receives, for example, the supply of AC power from the ceiling plate 200, but may also receive the supply of DC power.

Furthermore, an end portion 121a on one side of the first terminal 121 and an end portion 122a on one side of the second terminal 122 are each bent into an L shape. When the end portion 121a on one side of the first terminal 121 is inserted into the insertion hole 211 and the end portion 122a on the one side of the second terminal 122 is inserted into the insertion hole 212, the lighting device connector 100 is rotated and the lighting device connector is rotated 100 will be buckled on the ceiling plate 200. That is, the first terminal 121 and the second terminal 122 are also used to mechanically connect the joint 100 for a lighting fixture to the ceiling plate 200.

On the other hand, the third terminal 123 is a ground terminal. By inserting the end portion 123a on 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 plate 200. Unlike the first terminal 121 and the second terminal 122, an end portion 123a on one side of the third terminal 123 is not bent, and the third terminal 123 is not used for the mechanical connection of the joint 100 for lighting appliances. However, the end portion 123a on one side of the third terminal 123 may be bent, so that the third terminal 123 is used for the mechanical connection of the joint 100 for a lighting fixture.

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 connected to the connector 330 and the connector insertion port 150. In a state, it is connected to a metal terminal in the connector 330.

In addition, the length of a portion protruding from the first surface 111a of one end portion 123a of one side of the third terminal 123 may be longer than the end portion 121a of one side of the first terminal 121 from the first surface 111a. The length of the protruding portion and the length of the portion protruding from the first surface 111 a among the end portions 122 a of one side of the second terminal 122. Here, the length is more specifically a length in the Z-axis direction.

Therefore, when the connector 100 for a lighting fixture is mounted on the ceiling plate 200, the third terminal 123, which is a ground terminal, is easier to be electrically connected to the terminals in the ceiling plate 200 than the first terminal 121 and the second terminal 122. Sexual connection. Therefore, it is possible to improve safety when attaching the joint 100 for lighting fixtures to the ceiling plate 200.

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

With this, when the appliance body 310 and the lighting fixture connector 100 are electrically connected, the third terminal 123 as a ground terminal is easier to be electrically connected to the appliance body 310 earlier than the first terminal 121 and the second terminal 122. connection. Therefore, it is possible to improve safety when the fixture body 310 is attached to the lighting fixture joint 100.

The first locking member 131 and the second locking member 132 are resin members for holding the fixture main body 310 by the joint 100 for a lighting fixture. In other words, the first locking member 131 and the second locking member 132 are members for locking the fixture body 310 to the joint 100 for a lighting fixture.

The first locking member 131 is pressed from the inside of the casing 110 toward the outside by the elastic member 170, and protrudes from the first opening 111 c 1 toward the outside of the casing 110. The second locking member 132 is pressed from the inside of the housing 110 toward the outside by the elastic member 170, and protrudes from the second opening 111 c 2 toward the outside of the housing 110. The elastic member 170 is specifically a torsion spring, but may be other elastic members.

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

The first operation lever 161 and the second operation lever 162 are resin members that are operated by removing the fixture body 310 from the lighting fixture joint 100.

The first operating lever 161 is a member for moving the first locking member 131 in the Y-axis direction. The first operation lever 161 includes a first operated portion 161a and a first connection portion 161b.

The first operated portion 161a protrudes from an opening 112b provided in the cover 112 and is operated by a user. The opening 112b is an example of a 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 connection portion 161b is disposed in the recessed portion 131a of the first locking member 131, thereby engaging the first operating lever 161 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 operation lever 162 includes a second operated portion 162a and a second connection portion 162b.

The second operated portion 162a protrudes from an opening 112b provided in the cover 112 and is operated by a user. The opening 112 b is an example of a fourth opening provided on the second surface 112 a 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 recessed portion 132a of the second locking member 132, and thereby the second operating lever 162 and the second locking member 132 are engaged. 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 portion of the casing 110 toward the outer side of the casing 110, the second locking member 132 resists the elastic force of the elastic member 170 and moves toward the inside of the casing 110.

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

The locking portion 180 is a member for restricting the movement of the joint 100 for lighting fixtures with respect to the ceiling plate 200 in order to maintain the state in which the joint 100 for lighting fixtures is normally mounted on the ceiling plate 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.

One end of the coil spring inserted into the spring hole 182 is in contact with the bottom of the spring hole 182, and the other end is in contact with the surface inside the cover 112. Thereby, the lock portion 180 is pushed from the second surface 112a side to the first surface 111a side. When 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 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 joint 100 for lighting equipment with respect to the ceiling plate 200 is restricted. That is, the rotation of the joint 100 for lighting fixtures with respect to the ceiling plate 200 is locked.

As such, the protrusion 181 protrudes from the opening 111b provided on the first surface 111a side of the housing 110, and penetrates through the insertion hole 212 provided on the ceiling plate 200, so that the joint 100 for lighting fixtures is restricted from suctioning. The movement of the top plate 200.

The unlock button 140 is a button provided on the side wall of the housing 110 and used to push the protrusion 181 out of the insertion hole 212 by pressing down. The unlock button 140 is a resin member located on the outer side of the housing 110 with a portion thereof passing through a cutout portion provided on a side wall of the housing 110.

The convex portion 141 of the unlock button 140 is located in the groove portion 183 of the lock portion 180. The groove portion 183 forms an inclined groove in the X-axis direction which is 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 recessed portion 183 is pushed, whereby the lock portion 180 is moved toward the second surface 112a side. As a result, the projection 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 joint 100 for lighting fixtures with respect to the ceiling plate 200 is released. The user can detach the lighting fixture connector 100 from the ceiling tray 200 by pressing the unlock button 140 while rotating the lighting fixture connector 100 with respect to the ceiling tray 200.

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

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

In view of this, in the lighting fixture joint 100, the first position P1 of the other end portion 121b of the first terminal 121, the second position P2 of the other end portion 122b of the second terminal 122, and the third terminal 123 The third position P3 of the end portion 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 a triangle.

As a result, 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 triangles having three vertices at the first position P1, the second position P2, and the third position P3 may be any triangle. However, in the joint 100 for lighting appliances, this triangle is an isosceles triangle. That is, the first position P1, the second position P2, and the third position P3 are arranged to constitute three vertices of an isosceles triangle. In other words, the third position P3 is located on a vertical bisector which connects the first position P1 and the second position P2.

Thereby, the interval between the other end portion 121b of the first terminal 121 and the third end 123b of the third terminal 123 is equal to the distance between the other end 122b of the second terminal 122 and the third terminal 123. The interval between one end portions 123b. When the third terminal 123 is a ground terminal, it is easy to make the ends 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, at the joint 100 for lighting fixtures, 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; they are arranged on the negative X-axis side more than the straight line L. The unlock button 140 is unlocked; the other end 123b of the third terminal 123 is positioned on the X-axis positive side more 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. The center position C of the housing 110 is a position through which a rotation axis passes when the joint 100 for a lighting fixture is mounted on the ceiling plate 200.

As a result, the end portion 123b on 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. Therefore, the size of the housing 110 is small It also makes it difficult for the other end portion 123b of the third terminal 123 and the unlock button 140 to interfere with each other. That is, it is easier to miniaturize the size of the casing 110.

Furthermore, in the joint 100 for a lighting fixture, 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 are arranged side by side. An end portion 122b on the other side of 122 is positioned 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 portion 121b on the other side of the first terminal 121 and the end portion 122b on the other side of the second terminal 122.

As such, 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 In the above, the three terminals and the first locking member 131 and the second locking member 132 easily interfere with each other, making the miniaturization of the housing 110 in the Y-axis direction 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 at three vertices constituting a triangle. The results are good.

Furthermore, in the joint 100 for lighting fixtures, the first operating lever 161 (specifically, the first operated portion 161a) and the second operating lever 162 (specifically, the second operated portion 162a) are attached to Arranged side by side in the Y-axis direction. An end portion 121b on the other side of the first terminal 121 and an end portion 122b on the other side of the second terminal 122 are positioned between the first operated portion 161a and the second operated portion 162a.

As such, 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 In the above, the three terminals and the first operated portion 161a and the second operated portion 162a easily 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 as three vertices constituting a triangle. The results are good.

However, as described above, the end portions 121b on the other side of the first terminal 121, the end portions 122b on the other side of the second terminal 122, and the end portions 123b on the other side of the third terminal 123 cannot be arranged. Conductive components. For example, when viewed from the side of the second surface 112a, it is assumed that from the center of the first position P1, the second position P2, and the third position P3, a circular area within a radius r cannot be disposed with conductivity. Of the building. In this case, as shown in FIG. 7, if the first position P1, the second position P2, and the third position P3 are respectively arranged on a straight line with an interval r, the area A surrounded by a thick line is Do not place areas with conductive members. FIG. 7 is a diagram illustrating a region where a conductive member cannot be arranged when the first position P1, the second position P2, and the third position P3 are arranged on a straight line.

In contrast, when the first position P1, the second position P2, and the third position P3 constitute the three vertices of the isosceles triangle, the area B surrounded by a thick line in FIG. 8 cannot be equipped with a tool. Area of conductive member. FIG. 8 is a diagram illustrating a region where a conductive member cannot be arranged when the first position P1, the second position P2, and the third position P3 are the three vertices of the isosceles triangle.

Here, in FIG. 8, if the length r1 from the vertex corresponding to the third position P3 and down to the bottom side satisfies the condition r1 ≦ 1.13r, the area of the area B in FIG. 8 can be made in FIG. 8. The area of the area A is 7 or less. That is, 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 1, then in the isosceles triangle, the length from The length of the vertical line from the top of the vertex to the bottom, as long as it is below 1.13. Thereby, even if the housing 110 is miniaturized, it is easy to arrange a conductive member. That is, the miniaturization of the housing 110 can be made easier. The minimum 値 of r1 is, for example, (√3 / 2) × r.

In addition, the first locking member 131 and the second locking member 132 are symmetrical in shape, size, and arrangement. In contrast, the shape and size of the first operation lever 161 and the second operation lever 162 are slightly different. Specifically, the shapes and sizes of the first connection portion 161b and the second connection portion 162b are different.

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

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

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 above. It is the same when viewed from the side of the first surface 111a, the position of the end portion 121a on one side of the first terminal 121, the position of the end portion 122a on one side of the second terminal 122, and the end on 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 portion 121a of one side of the first terminal 121, the position of the end portion 122a of one side of the second terminal 122, and the position of the end portion 123a of one side of the third terminal 123 may be configured, etc. 3 vertices of a waist triangle.

[Effects, etc.]
As described above, the lighting fixture joint 100 is a lighting fixture joint for connecting the ceiling plate 200 and the fixture body 310 of the lighting fixture 300. The connector 100 for a lighting fixture includes a housing 110 (having a first surface 111a facing the ceiling plate 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 first terminal 121, the second terminal 122, and the third terminal 123 have one end portions protruding from the terminal insertion holes provided on the first surface 111a side of the housing 110, and the other end portions are respectively disposed on The connector insertion port 150 is on the second surface 112a side of the housing 110. The connector insertion opening 150 is an example of a recessed portion. When viewed from the second surface 112a side, the first position P1 of the end 121b on the other side of the first terminal 121, the second position P2 of the end 122b on the other side of the second terminal 122, and the third terminal 123 The third position P3 of the end 123b on the other side constitutes three vertices of the triangle.

Thereby, compared with the case where the 1st position P1, the 2nd position P2, and the 3rd position P3 are arrange | positioned on a straight line, it is easier to reduce the size of the housing 110. That is, the connector 100 for a lighting fixture that can be easily miniaturized can be realized.

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 uses the inner angle of the vertex corresponding to the third position P3 as the apex angle.

Thereby, it is easy to make the distance between the end portion 121b on the other side of the first terminal 121 and the end portion 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 to the bottom 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. That is, the miniaturization of the housing 110 can be made easier.

Further, for example, the joint 100 for lighting fixtures further includes a protrusion 181 protruding from an opening 111b provided on the first surface 111a side of the housing 110 and penetrating through an insertion hole 212 provided in the ceiling plate 200. The joint 100 for lighting fixtures is restricted from moving relative to the ceiling plate 200; 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 by pressing down. 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, the end portion 123b on 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. Therefore, the size of the housing 110 is small It also makes it difficult for the other end portion 123b of the third terminal 123 and the unlock button 140 to interfere with each other. That is, it is easier to miniaturize the size of the casing 110.

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

As such, 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 As a result, miniaturization of the housing 110 in the above-mentioned arrangement direction becomes 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 at three vertices constituting a triangle. The results are good.

Furthermore, for example, the joint 100 for lighting fixtures 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 for 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 an opening 112b provided on the second surface 112a side of the housing 110, and is used for The second locking member 132 is moved along the 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-mentioned arrangement direction; when viewed from the second surface 112a side, the end portion 121b on the other side of the first terminal 121 and the second terminal An end portion 122b on the other side of 122 is positioned between the first operated portion 161a and the second operated portion 162a.

As such, 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 As a result, miniaturization of the housing 110 in the above-mentioned arrangement direction becomes 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 as three vertices constituting a triangle. The results are good.

Furthermore, for example, the first operating lever 161 has a first connection portion 161b to connect the first operated portion 161a and the first locking member 131. The second operating lever 162 has a second connecting portion 162b to connect the second operated portion 162a and the second locking member 132. The first connection portion 161b and the second connection portion 162b are arranged side by side in a direction crossing the arrangement direction. When viewed from the second surface 112a side, the end portion 121b on the other side of the first terminal 121, the end portion 122b on the other side of the second terminal 122, and the end portion 123b on the other side of the third terminal 123 are positioned. Between the first connection portion 161b and the second connection 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.

This makes it easier to arrange the end portion 123b of the third terminal 123 on the other side in the space between the straight line L and the second connection portion 162b.

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

As described above, the safety of the lighting fixture joint 100 can be improved by providing the lighting fixture joint 100 with a ground terminal.

Furthermore, for example, the end portion 123b on the other side of the third terminal 123 faces the second surface more than the end portion 121b on the other side of the first terminal 121 and the end portion 122b on the other side of the second terminal 122. Protruding sideways.

With this, when the appliance body 310 and the lighting fixture connector 100 are electrically connected, the third terminal 123 as a ground terminal is easier to be electrically connected to the appliance body 310 earlier than the first and second terminals 121 and 122. connection. Therefore, it is possible to improve safety when the fixture body 310 is attached to the lighting fixture joint 100.

The lighting fixture 300 includes a lighting fixture joint 100 and a fixture body 310.

Thereby, the lighting fixture 300 which can make the lighting fixture joint 100 easy to miniaturize can be implemented.
