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 that faces the hook-type terminal block 200 toward 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 112, and is detachably connected to the connector 330 of the appliance body 310. The top view shape of the connector insertion opening 150 is slightly T-shaped, and the connector 330 is also a corresponding shape. The connector insertion port 150 is provided in, for example, a concave portion on the second surface 112a side of the housing 110.

The cover 112 is a plate-shaped component made of resin that covers the lower surface side of the main body 111. The cover 112 constitutes the lower surface (connection surface) of the housing 110, and an opening 112 b is provided in the center of the cover 112. From the opening 112b, the connector insertion port 150 and the first operated portion (not shown in the figure) of the first lever 161 and the second operated portion (not shown in the figure) of the second lever 162 are exposed to the outside.

The first terminal 121, the second terminal 122, and the third terminal 123 are metal plate-shaped components. The first terminal 121, the second terminal 122 and the third terminal 123 are fixed by screws inside the main body 111.

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

As shown in FIG. 4, the first terminal 121, the second terminal 122, and the third terminal 123 respectively have one end 121a, 122a, and 123a from the terminal insertion holes 111a1, 111a2 provided on the first surface 111a of the housing 110. , 111a3 protruding first protrusion 121a1, second protrusion 122a1, and third protrusion 123a1. The first protrusion 121a1, the second protrusion 122a1, and the third The lengths H1, H2, and H3 of the protrusion 123a1 in the axial direction are slightly the same. In other words, H1=H2=H3. For example, the lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 in the axial direction are slightly in the range of 3.5-20 mm. In other words, 3.5<H1=H2=H3<20mm. The lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 in the axial direction may also be slightly in the range of 5-12 mm. In other words, 5<H1=H2=H3<12mm. The lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 in the axial direction may also be slightly in the range of 7-8 mm.

The lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 in the axial direction are substantially the same, so that the lighting fixture adapter 100 can be formed into a thinner shape. In addition, since the adapter 100 for lighting equipment is formed to be thin, it can be easily packaged.

In addition, if the length H3 of the third protrusion 123a1 in the axial direction is shorter than the lengths H1 and H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction, the third protrusion 123a1 is inserted into the hook-up terminal block When contacting the third connected portion 223b of the third blade receiver 223 described later in 200, there is a problem of insufficient clamping area. In addition, in this case, the third connected portion 223b must be arranged in a direction close to the third protruding portion 123a1, which may also cause the third connected portion 223b to have insufficient insulation distance.

Therefore, compared with the case where the length H3 of the third protrusion 123a1 in the axial direction is shorter than the length H1, H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction, the first protrusion 121a1, the second protrusion The lengths H1, H2, and H3 of the protrusions 122a1 and the third protrusions 123a1 in the axial direction are slightly the same, so that the third protrusions 123a1 and the third blade receiving 223 described later can be ensured. The contact area of the third to-be-connected portion 223b can further obtain good insertability.

FIG. 5 is another embodiment of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1' of the present invention. As shown in FIG. 5, the third protruding portion 123a1' protrudes further to the first surface 111a side than the first protruding portion 121a1 and the second protruding portion 122a1. In other words, the length H3' of the third protruding portion 123a1' in the axial direction is longer than the lengths H1, H2 of the first protruding portion 121a1 and the second protruding portion 122a1 in the axial direction. In other words, H3'>H2 or H3'>H1. For example, the length H3' of the third protrusion 123a1' in the axial direction is longer than the length H1 of the first protrusion 121a1 in the axial direction in the range of 0.1-10mm, or 0.5-5mm, or 1-3mm. range. In other words, the relationship between the length H3' and the length H1 is 0.1<H3'-H1<10mm, or 0.5<H3'-H1<5mm, or 1<H3'-H1<3mm. Similarly, the length H3' of the third protrusion 123a1' in the axial direction is longer than the length H2 of the second protrusion 122a1 in the axial direction in the range of 0.1-10mm, or 0.5-5mm, or 1-3mm Range. In other words, the relationship between the length H3' and the length H2 is 0.1<H3'-H2<10mm, or 0.5<H3'-H2<5mm, or 1<H3'-H2<3mm. In addition, in this embodiment, the length H1 and the length H2 are slightly the same. In other words, the relationship between the length H1 and the length H2 is H1=H2. However, the length H1 and the length H2 may have different lengths. The length H3' of the third protrusion 123a1' in the axial direction is longer than the length H1, H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction. When the hook-type terminal block 200 is reached, the third protrusion 123a1' can be aligned with the third guide groove 233 first, which can facilitate the insertion. In addition, the third blade receiver 223 of the hook-type terminal block 200 can also be configured at a place farther from the first surface 211a, which can increase the insulation distance of the third blade receiver 223.

In other words, the length L2 can also be slightly equal to the difference between H3' and H1, that is, L2=H3'-H1, or the length L2 can also be slightly equal to the difference between H3' and H2, that is, L2=H3'-H2. In this way, in the case where the third protrusion 123a1' also needs to form a curved portion, the third protrusion can be formed by directly bending the part of the third protrusion 123a1' protruding from the first protrusion 121a1 and the second protrusion 122a1 The curved part of 123a1'.

The bent portion 122a11 is formed with a terminal connection portion 122a12 at a portion extending in the radial direction of the lighting fixture adapter 100.

By forming the terminal connecting portion 122a12 on the bent portion 122a11, when the lighting fixture adapter 100 is clamped to the hook-type terminal block 200, additional supporting force can be provided. Moreover, the terminal connection part 122a12 may be comprised by the hook part formed in the shape of a fishing hook. Thereby, the terminal connecting portion 122a12 can be hung on the second blade receiver 222 more reliably.

As shown in FIGS. 4 and 5, the terminal connection portion 122a12 is formed in a shape with a recessed center. Specifically, when viewed from the radial direction, the terminal connection portion 122a12 is formed in a shape having a substantially V-shaped cross section. With this shape, when the second terminal 122 is connected to the second blade receiver 222, it can be connected to the second connected portion 222b through the contact point on the bottom surface, thereby enabling the second terminal 122 to be more reliably connected to the second connected portion The 222b connection can be more stable, and the stability of the connection of the adapter 100 for lighting equipment to the hook-type terminal block 200 is improved. However, the cross section of the terminal connection portion 122a12 may also be formed in an inverted V shape, a U shape, an inverted U shape, etc., and the cross section of the terminal connection portion 122a12 may not be formed with a recess, but may be formed in a flat plate shape.

The enlarged portion 223b4 is formed so that the interval in the engagement direction becomes larger. As a result, since the enlarged portion 223b4 is formed with a larger interval in the engagement direction, the angle formed by the place where the enlarged portion 223b4 connects to the third base portion 223a becomes smaller, and the third terminal 123 enters and The opening and closing angle between the third base portion 223a and the enlarged portion 223b4 caused by the removal becomes smaller. Therefore, the deformation amount of the third base portion 223a caused by the opening and closing of the third blade receiver 223 when the third terminal 123 is engaged can be reduced by the absorption of the enlarged portion 223b4. Thereby, the fatigue deformation or fracture of the third blade receiver 223 due to long-term use can be reduced.

In this embodiment, the third connected portion 223b has an opening 223b1, a guiding portion 223b2, and an engaging portion 223b3.

[Configuration of terminal and plug-in part]

Next, the combination of the first terminal 121, the second terminal 122, and the third terminal 123 when the lighting fixture adapter 100 is viewed from the side of the first surface 111a will be described with reference to FIGS. 11-13, 19, and 20 state.

As shown in FIGS. 11-13, one end 121a of the first terminal 121, one end 122a of the second terminal 122, and one end 123a of the third terminal 123 are from the lighting fixture adapter 100 The first surface 111a protrudes, when one end 121a of the first terminal 121, one end 122a of the second terminal 122, and one end 123a of the third terminal 123 are viewed from the side of the first surface 111a, it is configured Are the three vertices of the triangle. One end 121a of the first terminal 121, one end 122a of the second terminal 122, and one end 123a of the third terminal 123 are each in order to ensure insulation from other terminals or conductive components. It is necessary to configure at a predetermined interval. It is assumed that the first position P1 of one end 121a of the first terminal 121, the second position P2 of one end 122a of the second terminal 122, and the third position P3 of one end 123a of the third terminal 123 are configured. In a straight line, the size of the housing 110 in the straight line direction may increase. And, the position referred to here (specifically, the first position P1, second position P2, and third position P3) refer to, for example, the center position (or the coordinates indicated by the center position) of one end of the terminal viewed from the first surface 111a side.

Therefore, in the lighting fixture adapter 100, one of the first position P1 of the one end 121a of the first terminal 121, the second position P2 of the one end 122a of the second terminal 122, and one of the third terminal 123 The third position P3 of the end 123a is not configured in 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 the same direction, the size of the housing 110 in the same direction can be miniaturized.

Furthermore, the triangle having the first position P1, the second position P2, and the third position P3 as three vertices may be any triangle, but the triangle in the lighting fixture adapter 100 is an isosceles triangle. In other words, the first position P1, the second position P2, and the third position P3 are configured to form three vertices of an isosceles triangle. In other words, the third position P3 is located at the vertical line between the first position P1 and the second position P2.

Thereby, the distance between the one end 121a of the first terminal 121 and the one end 123a of the third terminal 123 is the same as the one end 122a of the second terminal 122 and the one end 123a of the third terminal 123. The intervals between are equal. When the third terminal 123 is a ground terminal, the distance from each of the one end 121a of the first terminal 121 and the one end 122a of the second terminal 122 to the ground terminal can be made equal.

For example, when viewed from the side of the first surface 111a, it is assumed that the distance from the center of each of the first position P1, the second position P2, and the third position P3 is half No conductive components can be configured in the circular area within the diameter r. In this case, as shown in FIG. 19, 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 the thick line cannot be Configure the area of conductive components. FIG. 19 is a diagram showing an area where conductive components cannot be configured when the first position P1, the second position P2, and the third position P3 are arranged on a straight line.

In the case where the first position P1, the second position P2, and the third position P3 are configured as the three vertices of an isosceles triangle, the area B surrounded by the thick line in FIG. 20 cannot be configured with conductive components Area. FIG. 20 is a diagram showing an area where conductive components cannot be arranged when the first position P1, the second position P2, and the third position P3 are configured as three vertices of an isosceles triangle.

3/3)×r。 Here, in FIG. 20, if the length r1 of the perpendicular formed from the vertex corresponding to the third position P3 to the opposite base meets the relationship of r1≦1.13r, the area of the area B in FIG. 20 can be Area A of 19 is less than the area. In other words, if the base length of the isosceles triangle formed by the first position P1, the second position P2, and the third position P3 is set to 1, then only the vertex of the isosceles triangle corresponding to the third position P3 The length of the perpendicular formed by the opposite bottom side can be set to 1.13 or less. In this way, even if the housing 110 is miniaturized, it is easy to configure conductive components. In other words, the case 110 can be easily reduced in size, and the insulation distance of the first terminal 121, the second terminal 122, and the third terminal 123 can be ensured at the same time. In addition, the minimum value of r1 can be, for example, (

3/3)×r.

Above, the configuration of the first terminal 121, the second terminal 122, and the third terminal 123 when viewed from the side of the first surface 111a has been described. Also, when viewed from the second surface 112a side, the position of the other end 121b of the first terminal 121, the position of the other end 122b of the second terminal 122, and the position of the other end 123b of the third terminal 123 It also constitutes the three tops of a triangle point. In this case, the position of the other end 121b of the first terminal 121, the position of the other end 122b of the second terminal 122, and the position of the other end 123b of the third terminal 123 may also be configured as an isosceles triangle. 3 vertices.

The first position P1 of one end 121a of the first terminal 121, the second position P2 of one end 122a of the second terminal 122, and the third position of one end 123a of the third terminal 123 are listed here. The configuration relationship of P3. And, referring to FIG. 10, the first position P1b of the first insertion portion 231a, the second position P2b of the second insertion portion 232a, and the third position P3b of the third insertion portion 233a of the hook-type terminal block 200 are also applicable to the first position The configuration relationship of P1, the second position P2, and the third position P3. And, referring to FIG. 6, the other ends 221d, 222d, and 223d of the first blade receiver 221, the second blade receiver 222, and the third blade receiver 223 are also applicable to the first position P1, the second position P2, and the third position P3.
