The axial lengths H1 , H2 , and H3 of the first protruding portion 121a1 , the second protruding portion 122a1 , and the third protruding portion 123a1 are substantially the same. In other words, H1=H2=H3. For example, the axial lengths H1 , H2 , and H3 of the first protruding portion 121a1 , the second protruding portion 122a1 , and the third protruding portion 123a1 are in the range of 3.5-20 mm. In other words, 3.5<H1=H2=H3<20mm. The axial lengths H1 , H2 , and H3 of the first protruding portion 121 a1 , the second protruding portion 122 a 1 , and the third protruding portion 123 a 1 may also be in the range of 5-12 mm. In other words, 5<H1=H2=H3<12mm. The lengths H1 , H2 , and H3 in the axial direction of the first protruding portion 121a1 , the second protruding portion 122a1 , and the third protruding portion 123a1 may also be within the range of 7-8 mm. In other words, 7<H1=H2=H3<8mm.

The lengths H1 , H2 , and H3 in the axial direction of the first protrusion 121a1 , the second protrusion 122a1 , and the third protrusion 123a1 are substantially the same, whereby the lighting fixture adapter 100 can be thinned. Moreover, since the adaptor 100 for lighting fixtures is formed thin, it can be easily packaged.

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

Therefore, compared with the case where 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 first protrusion 121a1, the second protrusion The lengths H1, H2, and H3 in the axial direction of the protruding portion 122a1 and the third protruding portion 123a1 are approximately the same, so that the contact area between the third protruding portion 123a1 and the third connected portion 223b of the third blade receiver 223 described later can be ensured, and further Good insertability can be obtained.

FIG. 5 shows another embodiment of the first protruding portion 121a1, the second protruding portion 122a1, and the third protruding portion 123a1' of the present invention. As shown in FIG. 5, the 3rd protrusion part 123a1' protrudes further toward the 1st surface 111a side than the 1st protrusion part 121a1 and the 2nd protrusion part 122a1. In other words, the length H3' of the third protrusion 123a1' in the axial direction is longer than the lengths H1 and H2 of the first protrusion 121a1 and the second protrusion 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 0.1-10 mm, or in the range of 0.5-5 mm, or in the range of 1-3 mm Scope. 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 0.1-10 mm, or in the range of 0.5-5 mm, or in the range of 1-3 mm 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 substantially 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 lengths H1 and H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction, whereby, When inserting the adapter 100 for lighting fixtures into the hook-and-loop socket 200, the third protrusion 123a1' can be aligned with the third guide groove 233 first, and the insertion can be facilitated. In addition, the third blade holder 223 of the pull-out socket 200 can also be arranged at a place far away from the first surface 211a, so that the insulation distance of the third blade holder 223 can be increased.

As shown in FIGS. 4 and 5 , the first protruding portion 121a1 of the first terminal 121 has a bent portion 121a11. The bent portion 121a11 can be used to hang the adapter 100 for lighting fixtures on the hook-and-loop socket 200 . The bent portion 121a11 of the first terminal 121 is a portion of the first terminal 121 which forms an angle with the axial direction in the axial cross section. In this embodiment, the curved part 121a11 extends along the radial direction of the adapter 100 for lighting fixtures. However, the curved portion 121a11 may extend along the horizontal direction, or may extend at an angle with respect to the horizontal direction. In addition, as shown in FIG. 5 , the length L1 of the curved portion 121a11 in the radial direction may be the same as the length of the portion of the third protruding portion 123a1 ′ protruding from the first protruding portion 121a1 and the second protruding portion 122a1 . In other words, the length L1 can also be slightly equal to the difference between H3' and H1, that is, L1=H3'-H1, or the length L1 can also be slightly equal to the difference between H3' and H2, that is, L1=H3'-H2. Therefore, when the third protrusion 123a1' also needs to form a curved portion, the third protrusion can be formed by directly bending the portion of the third protrusion 123a1' that protrudes from the first protrusion 121a1 and the second protrusion 122a1 123a1' bend.

A terminal connection portion 121a12 is formed in a portion of the bent portion 121a11 extending along the radial direction of the lighting fixture adapter 100 . In the present embodiment, the first terminal 121 is connected by a portion of the terminal connecting portion 121a12 and a first connected portion 221b of the first blade receiver 221 described later. By forming the terminal connecting portion 121a12 on the bent portion 121a11, when the adapter 100 for lighting fixtures is engaged with the hook-type terminal block 200, an additional supporting force can be provided. Moreover, the terminal connection part 121a12 may be comprised by the hook part formed in the shape of a fish hook. Thereby, the terminal connection part 121a12 can hang on the 1st blade holder 221 more reliably.

As shown in FIGS. 4 and 5 , the terminal connection portion 121a12 is formed in a shape with a hollow center. Specifically, the terminal connection portion 121a12 is formed in a shape having a substantially V-shaped cross section when viewed in the radial direction. With this shape, when the first terminal 121 is connected to the first blade holder 221, the first terminal 121 can be connected to the first connected part 221b through the contact point on the bottom surface, so that the first terminal 121 and the first connected part can be more reliably connected. 221b is connected to improve the stability of the connection of the adapter 100 for lighting equipment to the drop-type terminal block 200 . However, the cross section of the terminal connection portion 121a12 may be formed in an inverted V shape, a U shape, an inverted U shape, or the like, and the cross section of the terminal connection portion 121a12 may be formed in a flat plate shape without forming a depression.

In the present embodiment, as shown in FIGS. 4 and 5 , the cross-sectional shape in the axial direction of the first protruding portion 121 a 1 is an inverted L-shape. However, the cross section of the first protruding portion 121a1 in the axial direction may be an inverted J shape, an inverted U shape, or the like. In addition, the first protruding portion 121a1 may not have the curved portion 121a11 , and the first protruding portion 121a1 itself is connected to the first connected portion 221b of the first blade holder 221 .

Furthermore, as shown in FIGS. 4 and 5 , the second protruding portion 122a1 of the second terminal 122 has a bent portion 122a11. The bent portion 122a11 can be used to hang the adapter 100 for lighting fixtures on the hook-and-loop socket 200 . The bent portion 122a11 of the second terminal 122 is a portion of the second terminal 122 that forms an angle with the axial direction in the axial cross section. In this embodiment, the curved part 122a11 extends along the radial direction of the adapter 100 for lighting fixtures. However, the curved portion 122a11 may extend along the horizontal direction, or may extend at an angle with respect to the horizontal direction. In addition, as shown in FIG. 5 , the length L2 of the curved portion 122a11 in the radial direction may be the same as the length of the portion of the third protrusion portion 123a1 ′ protruding from the first protrusion portion 121a1 and the second protrusion portion 122a1 . 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. Thereby, in the third protrusion When the 123a1' also needs to form a curved portion, the curved portion of the third protrusion 123a1' can be formed by directly bending the portion of the third protrusion 123a1' protruding from the first protrusion 121a1 and the second protrusion 122a1.

A terminal connecting portion 122a12 is formed in a portion of the bent portion 122a11 extending along the radial direction of the lighting fixture adapter 100 . In the present embodiment, the second terminal 122 is connected by a portion of the terminal connecting portion 122a12 and a second connected portion 222b of the second blade receiver 222 described later. By forming the terminal connecting portion 122a12 on the bent portion 122a11, when the lighting fixture adapter 100 is snapped to the hook-and-loop socket 200, an 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 hook. Thereby, the terminal connection part 122a12 can hang on the 2nd blade holder 222 more reliably.

As shown in FIGS. 4 and 5 , the terminal connection portion 122a12 is formed in a shape with a hollow center. Specifically, the terminal connection portion 122a12 is formed in a shape having a substantially V-shaped cross section when viewed in the radial direction. With this shape, when the second terminal 122 is connected to the second blade 222, the second terminal 122 can be connected to the second connected portion 222b through the contact point on the bottom surface, thereby making it possible to make the second terminal 122 and the second connected portion more reliably. The 222b connection can be more stable, which improves the stability of the connection of the adapter 100 for a lighting fixture to the hook-up socket 200 . However, the cross section of the terminal connecting portion 122a12 may be formed in an inverted V shape, a U shape, an inverted U shape, or the like, and the cross section of the terminal connecting portion 122a12 may be formed in a flat plate shape without forming a depression.

In the present embodiment, as shown in FIGS. 4 and 5 , the cross-sectional shape in the axial direction of the second protruding portion 122a1 is an inverted L-shape. However, the cross section of the second protrusion 122a1 in the axial direction may be an inverted J shape, an inverted U shape, or the like. In addition, the second protruding portion 122a1 may not have the curved portion 122a11 , and the second protruding portion 122a1 itself is connected to the second connected portion 222b of the second blade holder 222 .

By forming the bent portion 121a11 and the bent portion 122a11 of the first terminal 121 and the second terminal 122, respectively, when the first terminal 121 and the second terminal 122 are connected to the first blade 221 and the second blade 222, an additional support.

As shown in FIGS. 4 and 5 , the third protrusions 123a1 and 123a1' of the third terminals 123 and 123' are in the shape of long straight pins. In other words, no curved portion is formed in the third protrusions 123a1 and 123a1'. Since the adapter 100 for lighting fixtures has three terminals, it becomes difficult to insert the adapter 100 for lighting fixtures into the drop socket 200 if all three terminals are formed with a bent portion. Therefore, in the present embodiment, the third protrusions 123a1 and 123a1' are in the shape of long straight pins. Thereby, when inserting the adapter 100 for lighting fixtures into the pull-out socket 200, it is not necessary to align the three curved parts at the same time, and the insertion can be made easy. In other words, the insertability of the adapter 100 for lighting fixtures can be improved. In addition, the user can visually determine the positions of the third terminals 123 and 123', and can also know the insertion direction. In addition, the third protrusions 123a1 and 123a1' are in the shape of long straight pins, so that the position where the third protrusions 123a1 and 123a1' are inserted into the third insertion part 233a can be easily positioned so that the lighting fixture adapter 100 can be inserted into the Getting to the pin-out terminal block 200 becomes easy. However, one end portion 123a, 123a1' of the third terminals 123, 123' may have a bent portion.

In addition, in order to make the rotation of the third protrusions 123a1 and 123a1' in the third guide groove 233 described later more stable, the cross-sectional shape of the third protrusions 123a1 and 123a1' viewed from the first surface 111a corresponds to the third guide. The shape of the groove 233 , in other words, the cross-sectional shape of the third protrusions 123a1 and 123a1 ′ as viewed from the first surface 111a is formed in a shape that can smoothly rotate in the third guide groove 233 . For example, the diameter of the third protrusions 123a1, 123a1' of the third terminals 123, 123' The cross-section system of the direction may be any of a square, a fan, a crescent, a semicircle, an arc, and the like. Thereby, the rotation of the third terminals 123, 123' in the third guide groove 233 in the circumferential direction can be more stable. In other words, the stability at the time of engagement can be increased. In addition, the cross-sectional shape of each of the first protruding portion 121a1 and the second protruding portion 122a1 viewed from the first surface 111a may correspond to the shape of the first guide groove 231 and the second guide groove 232, or may be a square, Any of a fan shape, a crescent shape, a semicircle shape, a circular arc shape, and the like. In addition, the cross-sectional shape of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1, 123a1' viewed from the first surface 111a may be any shape corresponding to the first guide groove as long as it can be smoothly guided 231 , the shape of the second guide groove 232 and the third guide groove 233 .

The locking portion is provided with a protrusion 181 .

When the adapter 100 for lighting fixtures is rotated so that the first terminal 121 reaches the end of the first guide groove 231 and the second terminal 122 reaches the end of the second guide groove 232, the position of the protrusion 181 and the second guide groove 232 The positions of the protrusions 181 overlap with each other, and the protrusion 181 protrudes from the first surface 111 a of the housing 110 and penetrates into the second guide groove 232 by the biasing force (elastic force) of the coil spring. In this state, the rotation of the adapter 100 for lighting fixtures with respect to the hook-type socket 200 is restricted. In other words, the rotation of the adapter 100 for lighting fixtures with respect to the hook-type socket 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 is inserted into the second guide groove 232 provided in the hook-type socket 200, thereby restricting the lighting fixture adapter 100 Movement relative to the drop-out terminal block 200 .

[Arrangement of terminals and inserts]

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

As shown in FIGS. 11 to 13 , one end 121 a of the first terminal 121 , one end 122 a of the second terminal 122 , and one end 123 a of the third terminal 123 are obtained from the lighting fixture adapter 100 . When the first surface 111a protrudes, 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. are the three vertices of the triangle. One end of the first terminal 121 121a, one end portion 122a of the second terminal 122, and one end portion 123a of the third terminal 123 must be separated by a predetermined distance in order to ensure insulation from other terminals or components having electrical conductivity. configured at intervals. It is assumed that the first position P1 of the one end portion 121a of the first terminal 121, the second position P2 of the one end portion 122a of the second terminal 122, and the third position P3 of the one end portion 123a of the third terminal 123 are arranged at On a straight line, the dimension of the casing 110 in the straight line direction may increase. In addition, the positions referred to here (specifically, the first position P1, the second position P2, and the third position P3) refer to, for example, the center position (or the center position of one end of the terminal as viewed from the first surface 111a side). coordinates indicated by the system center position).

Therefore, in the adapter 100 for lighting fixtures, the first position P1 of the one end portion 121a of the first terminal 121 , the second position P2 of the one end portion 122a of the second terminal 122 , and one of the third terminal 123 The third position P3 of the end 123a is not arranged 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 casing 110 in the same direction can be reduced.

In addition, 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 arranged so as to constitute three vertices of an isosceles triangle. In other words, the third position P3 is located on the mid-perpendicular line between the first position P1 and the second position P2.

The third terminal 123 is a ground terminal In this case, the distances from one end 121a of the first terminal 121 and one end 122a of the second terminal 122 to the ground terminal can be easily made equal.

However, in this arrangement, the one end portion 121a of the first terminal 121, the one end portion 122a of the second terminal 122, and the one end portion 123a of the third terminal 123 cannot be arranged around each of the sexual components. For example, when viewed from the side of the first surface 111a, it is assumed that no conductive element can be placed in a circular area within a radius r from the center of each of the first position P1, the second position P2, and the third position P3. . 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 therebetween, the region A surrounded by the thick line cannot be arranged The area of a component with electrical conductivity. FIG. 19 is a diagram showing a region where a device having conductivity cannot be arranged when the first position P1 , the second position P2 , and the third position P3 are arranged on a straight line.

When the first position P1, the second position P2, and the third position P3 are configured as three vertices of an isosceles triangle, the region B surrounded by the thick line in FIG. area. 20 is a diagram showing a region where a device having conductivity cannot be placed 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 vertical line formed from the vertex corresponding to the third position P3 to the opposite base satisfies the relationship of r1≦1.13r, the area of the region B in FIG. 20 can be The area of the area A of 19 is below. In other words, 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 only the vertex corresponding to the third position P3 in the isosceles triangle needs to be The length of the vertical line formed to the opposing bottom side should just be 1.13 or less. Thereby, even if the casing 110 is miniaturized, it is possible to easily arrange components having conductivity. In other words, the housing 110 can be easily miniaturized, and the insulation distances 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 may be, for example, (

3/3)×r.

In the above, the arrangement|positioning of the 1st terminal 121, the 2nd terminal 122, and the 3rd terminal 123 in the case of seeing from the 1st surface 111a side was demonstrated. Furthermore, 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 vertices of a triangle. 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.

Here, the first position P1 of the one end portion 121a of the first terminal 121 , the second position P2 of the one end portion 122a of the second terminal 122 , and the third position of the one end portion 123a of the third terminal 123 are listed. The configuration relationship of P3. 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 pull-out socket 200 are also applicable to the first position The configuration relationship of P1, the second position P2 and the third position P3. 6, the other ends 221d, 222d, 223d of the first blade receiving 221, the second blade receiving 222 and the third blade receiving 223 are also applicable to the first position P1, the second position P2 and the third position P3 configuration relationship.
