[0075] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiment is only an embodiment of a component of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0076] Example 1

[0077] like Figure 1 、 Figure 2 and Figure 3 As shown, the junction box 100 provided by the embodiment of the present invention includes a housing 110 , a connection terminal 120 and a wire pressing spring 130 .

[0078] The housing 110 has a wire inlet 111 extending therethrough, that is, the housing 110 has an inner cavity. The wiring terminals 120 and the wire pressing spring 130 are located within the inner cavity of the housing 110, and a wire clamping space is formed between the wiring terminals 120 and the wire pressing spring 130. The wire pressing spring 130 is positioned closer to the wire inlet 111 than the wiring terminals 120.

[0079] like Figure 4As shown, the terminal block 120 comprises a wire abutment portion 121 and a mounting portion 122 disposed opposite each other, as well as a connecting plate 123. The mounting portion 122 is disposed adjacent to the housing 110, thereby securing the terminal block 120 within the housing 110. The connecting plate 123 connects the wire abutment portion 121 and the mounting portion 122. The connecting plate 123 is provided with adjacent insertion spaces 1231 and a hanging support portion 1232. The insertion space 1231 extends through the connecting plate 123, while the hanging support portion 1232 is disposed away from the wire abutment portion 121 and closer to the mounting portion 122.

[0080] like Figure 5 As shown, the wire pressing spring 130 has a first free portion 131 and a first fixed portion 132. A wire clamping space is formed between the first free portion 131 and the wire abutting portion 121. Relative to the first fixed portion 132, the first free portion 131 is close to the wire clamping space. When the first free portion 131 of the wire pressing spring 130 is subjected to an external force close to the first fixed portion 132, the first free portion 131 is also away from the wire clamping space. The fixing seat can include a hanging area 1321, which penetrates into the insertion space 1231 from one side of the wire inlet 111 and hooks onto the hanging support portion 1232, that is, the hanging support portion 1232 supports the hanging area 1321.

[0081] Of course, the first free portion 131 and the first fixed portion 132 of the wire pressing spring 130 are relative. Since the terminal 120 has a snap-fitting space and a hanging support portion 1232, the wire pressing spring 130 has a hanging area 1321 that matches the snap-fitting space and the hanging support portion 1232. This allows the first fixed portion 132 of the wire pressing spring 130 to be at least partially supported by the terminal 120, thereby avoiding being completely supported by the housing 110, which would lead to the problem of concentrated force on the housing 110 when the wire pressing spring 130 is subjected to force.

[0082] The plug-in space 1231 may be in a U-shape on the connecting plate 123 , that is, it is set through the middle of the connecting plate 123 , or it may not be in a U-shape, but connected to the edge of the connecting plate 123 .

[0083] A wire clamping space is formed between the first free portion 131 and the wire abutment portion 121, whereby the first free portion 131 is moved closer to or away from the wire abutment portion 121 under the action of external force, thereby increasing or decreasing the size of the wire clamping space, so as to facilitate the wire to pass through the wire clamping space or be clamped in the wire clamping space.

[0084] To facilitate the straight-line insertion of the wires and their clamping in the wire-clamping spaces, the axes of the wire inlets 111 and the wire-clamping spaces are aligned. Obviously, the number of wire inlets 111 can be equal to the number of wire-clamping spaces, as well as the number of wire-pressing springs 130 and terminal blocks 120.

[0085] In order to further alleviate the problem of concentrated force on the housing 110 when the wire pressing spring 130 is subjected to force, in the embodiment of the present invention, the first free portion 131 can partially penetrate into the insertion space 1231 and abut against the wire abutting portion 121 (see Figure 7 ). Among them, the wire abutment portion 121 is located on the side of the connecting plate 123 away from the wire inlet 111. After the first free portion 131 penetrates the insertion space 1231 from the side of the wire inlet 111, it abuts the wire abutment portion 121 under normal conditions, and a wire clamping space is formed between the wire abutment portion 121 and the first free portion 131. The first free portion 131 can abut the wire abutment portion 121 under normal conditions (when there is no external force to deform), that is, under normal conditions, the wire clamping space is small and the wire can be clamped therein. When the first free portion 131 is subjected to external force, it moves away from the wire abutment portion 121, thereby increasing the size of the wire clamping space, so that the wire can be inserted from the wire inlet 111 into the wire clamping space.

[0086] Therefore, in the embodiment of the present invention, the first fixed portion 132 and the first free portion 131 of the wire pressing spring 130 on the junction box 100 are partially inserted into the plug-in space 1231 and rest against the terminal 120, so that when the wire pressing spring 130 is subjected to force, the pressure is at least partially transmitted to the terminal 120, and then transmitted to the housing 110 by the terminal 120, thereby avoiding the problem of excessive concentration of pressure applied by the wire pressing spring 130 on the housing 110.

[0087] In the embodiment of the present invention, the wire abutting portion 121 may include a wire abutting surface, which is disposed toward the mounting portion 122 and may be a serrated surface 1211 (see FIG. Figure 6 ) to increase the static friction force holding the wire in the wire clamping space. The serrations of each serration on the serrated surface 1211 may extend perpendicularly to the axis of the wire inlet 111. Of course, the wire abutment portion 121 may also include a wire abutment back surface, which is disposed opposite the wire abutment surface and can be positioned against the inner wall of the housing 110, thereby improving the stability of the terminal block 120 within the housing 110.

[0088] The hooking area 1321 can be formed by the flange of the first fixing portion 132 away from the first free portion 131 (see Figure 5The cross section of the hanging area 1321 may be arc-shaped so as to be able to overlap the hanging support portion 1232. The hanging area 1321 may include a hanging surface, which faces the hanging support portion 1232 and faces away from the first free portion 131. Obviously, the hanging surface is a pressure-bearing surface of the wire pressing spring 130. When the first free portion 131 of the wire pressing spring 130 is subjected to external force, the hanging surface bears pressure and abuts against the hanging support portion 1232.

[0089] The mounting portion 122 includes a mounting surface 1221, which is used to fit the inner wall of the shell 110 and face away from the wire abutment portion 121. The shell 110 is provided with a pressing port 112 and a pressing member 113. The pressing port 112 passes through the inside and outside of the shell 110. The pressing member 113 is movably arranged on the pressing port 112 along the axial direction of the pressing port 112, and the pressing port 112 and the pressing member 113 are arranged away from the mounting surface 1221. The first free portion 131 of the wire pressing spring 130 is arranged close to the pressing port 112 and the first free portion 131 is away from the pressing port 112, that is, the first fixed portion 132 is arranged close to the mounting portion 122. After passing through the pressing port 112, the pressing member 113 abuts against the first free portion 131, and under the action of an external force outside the shell 110, the first free portion 131 is driven to be close to the first fixed portion 132, that is, away from the wire abutment portion 121.

[0090] In an embodiment of the present invention, the axial direction of the wire inlet 111 and the axial direction of the pressing port 112 can be perpendicular to each other, that is, after the external wire is inserted into the wire clamping space from the wire inlet 111, the pressing member 113 can apply deformation pressure to the first free portion 131 in a direction perpendicular to the wire insertion direction. Moreover, the axial direction of the wire inlet 111 is parallel to the surface where the mounting surface 1221 is located, and the axial direction of the pressing port 112 is perpendicular to the mounting surface 1221. Of course, in some embodiments, the axis of the wire inlet 111 and the axis of the pressing port 112 may not be perpendicular to each other, so long as the function of the wire pressing spring 130 can be achieved.

[0091] like Figure 2 and Figure 5As shown, the wire pressing spring 130 also includes an arc-shaped bending area 133, and the first fixed portion 132 also includes a first transition area 1322. The first transition area 1322 connects the arc-shaped bending portion and the hanging area 1321. The first free portion 131 includes a narrow area 1311 and a second transition area 1312. The second transition area 1312 is connected between the arc-shaped bending area 133 and the narrow area 1311 and abuts the pressing member 113. The narrow area 1311 penetrates the insertion space 1231 and abuts the wire abutment portion 121. The first transition area 1322 and the second transition area 1312 are arranged opposite each other, and the hanging area 1321 is formed by flanging from the first transition area 1322 in a direction away from the second transition area 1312. In the wire-pressing spring 130, the extension surfaces of the first transition zone 1322, the second transition zone 1312, and the narrow zone 1311 are all inclined. From the mounting portion 122 to the pressing opening 112, the first transition zone 1322, the second transition zone 1312, and the narrow zone 1311 gradually move away from the wall surface of the wire inlet 111. As a result, the inclination of the narrow zone 1311 and the second transition zone 1312 does not prevent the wire from entering the wire-clamping space (or rather, it has a certain guiding effect). Furthermore, because the extension surfaces of the narrow zone 1311 and the second transition zone 1312 do not extend along the axial direction of the wire inlet 111, the narrow zone 1311 and the second transition zone 1312 can exert a relatively large elastic force on the wire-contacting portion 121.

[0092] It should be understood that the wire-pressing spring 130 is integrally formed or integrally provided with a metallic elastic material, and the second transition region 1312 is elastic and capable of appropriate deformation. The arc-shaped bending region 133 and the first transition region 1322 can abut the inner wall of the housing 110. As a result, the wire-pressing spring 130 is supported directly by the housing 110 in addition to being supported by the terminal block 120, thus providing greater stability within the housing 110.

[0093] In order to facilitate the hooking of the hanging area 1321 into the plug-in space 1231 and then hook it on the hanging support portion 1232, so that the hanging support portion 1232 can support the hanging area 1321, and to improve the reliability of the hooking of the hanging area 1321 on the hanging support portion 1232, the connecting plate 123 is also tilted relative to the mounting surface 1221 in the shell 110. From the mounting portion 122 to the pressing port 112, the connecting plate 123 gradually approaches the wall where the wire inlet 111 is located. In other words, the extension surface of the connecting plate 123 is roughly perpendicular to the extension surfaces of the narrow area 1311, the first transition area 1322, and the second transition area 1312 in the wire pressing spring 130. Moreover, the tilted setting of the connecting plate 123 can also make the wire abutment portion 121 close to the wall where the wire inlet 111 is located, reducing the size of the junction box 100.

[0094] It should be noted that the inclined arrangement of the connecting plate 123 and the wire pressing spring 130 is relative to the mounting surface 1221 of the terminal block 120 . The mounting surface 1221 is considered to be horizontally arranged in the housing 110 unless there are special circumstances.

[0095] In the embodiment of the present invention, Figure 4 As shown, the terminal block 120 may further include a positioning portion 124. The positioning portion 124 extends from the wire contact portion 121 toward the wall of the wire inlet 111. The positioning portion 124 may abut against the inner wall of the housing 110, thereby further improving the stability of the terminal block 120 within the housing 110. Of course, the positioning portion 124 may also be suspended and not abut against the inner wall of the housing 110.

[0096] The junction box 100 may include at least two parallel-connected terminals 120, with the connection direction of the at least two terminals 120 defined as the width direction. The width dimension of the positioning portion 124 may be equal to the width dimension of the insertion space 1231. Alternatively, the outer dimensions of the positioning portion 124 may be equal to the outer dimensions of the insertion space 1231, specifically, the length, width, and back dimensions of the positioning portion 124 and the insertion space 1231 being identical. In this case, the positioning portion 124 may be formed by folding over a metal portion of the insertion space.

[0097] Furthermore, the width of the connection plate 123 and the width of the wire contact portion 121 may be equal.

[0098] In order to enable the pressing member 113 disposed on the pressing opening 112 to drive the first free portion 131 to move when it moves axially, the line along which the pressing member 113 can move in a direction perpendicular to the mounting surface 1221 at least partially overlaps with the first free portion 131. In other words, in a direction perpendicular to the mounting surface 1221, the orthographic projection of the first free portion 131 on the mounting surface 1221 overlaps with the orthographic projection of the pressing member 113 on the mounting surface 1221. However, due to the arrangement of the positioning portion 124 on the aforementioned terminal block 120, the positioning portion 124 may be located between the pressing member 113 and the first free portion 131. Obviously, the positioning portion 124 should avoid the force exerted by the pressing member 113 on the first free portion 131.

[0099] In the embodiment of the present invention, the pressing member 113 has a pressing foot 1131 (see Figure 3), the pressing foot 1131 extends toward the first free portion 131 and avoids the positioning portion 124. Specifically, an avoidance hole can be provided in the positioning portion 124 so that the pressing foot 1131 can abut the first free portion 131 after passing through. Alternatively, as in the present application, the positioning portion 124 can have a smaller width, while the first free portion 131 and the pressing foot 1131 have a larger width at the location where they abut. Therefore, the pressing foot 1131 can pass through both sides of the positioning portion 124 and abut the first free portion 131.

[0100] The first free portion 131 may include a narrow area 1311 and a second transition area 1312 . Since the narrow area 1311 penetrates the insertion space 1231 , the second transition area 1312 is located outside the insertion space 1231 for abutting against the pressing member 113 . Among them, relative to the narrow area 1311, the second transition area 1312 is close to the wire inlet 111 and away from the wire abutment portion 121. The narrow area 1311 can penetrate into the plug-in space 1231 and abut against the wire abutment portion 121, that is, the width dimension of the narrow area 1311 can be less than or equal to the width dimension of the plug-in space 1231, and the width dimension of the second transition area 1312 is greater than the width dimension of the narrow area 1311, so as to limit the penetration depth of the narrow area 1311. The second transition area 1312 is located outside the plug-in space 1231 and abuts against the pressing piece 113. Under the action of the pressing piece 113, it can drive the first free portion 131 to deform.

[0101] In order to enable the pressing foot 1131 to abut the second transition zone 1312 of the first free portion 131 without contacting the positioning portion 124 located between the pressing member 113 and the first free portion 131, the width dimension of the second transition zone 1312 is greater than the width dimension of the positioning portion 124. The pressing foot 1131 can avoid the positioning portion 124 and abut the second transition zone 1312, that is, the pressing foot 1131 maintains a distance from the positioning portion 124.

[0102] Although in an embodiment of the present invention, the second transition zone 1312 and the first free portion 131 are arranged to be inclined relative to the mounting surface 1221, in order to improve the pressing effect of the pressing member 113 on the second transition zone 1312, the end surface of the pressing foot 1131 facing the second transition zone 1312 is a horizontal plane, and the part of the second transition zone 1312 abutting against the pressing foot 1131 can also be a horizontal plane (parallel to the mounting surface 1221).

[0103] In this embodiment of the present invention, the wire pressing spring 130 is generally U-shaped, perpendicular to the width, with the narrow region 1311 and the attachment region 1321 located at the ends of the U. In other words, the second transition region 1312 and the first transition region 1322 are generally parallel to each other. Furthermore, to allow the attachment region 1321 to penetrate the insertion space 1231, the width of the attachment region 1321 is less than or equal to the width of the insertion space 1231, while the width of the second transition region 1312 is greater than the width of the insertion space 1231.

[0104] like Figure 4 As shown, in this embodiment of the present invention, the terminal block 120 may further include a coupling portion 125 and a strain portion 126. The strain portion 126 connects the mounting portion 122 and the coupling portion 125, and extends from the mounting portion 122 in a direction away from the mounting surface 1221. The coupling portion 125 is used to electrically connect to the electrical components of the junction box 100. The strain portion 126 is deformable, providing the coupling portion 125 with the ability to move upon application of force, thereby improving the reliability of the electrical connection between the coupling portion 125 and the other electrical components. Furthermore, in a direction perpendicular to the mounting surface 1221, the coupling portion 125 can move away from or closer to the mounting portion 122 relative to the wire abutment portion 121. Of course, the coupling portion 125 being farther away from the mounting portion 122 relative to the wire abutment portion 121 allows the strain portion 126 to have a sufficient length, further improving the strain portion 126's deformability and the reliability of the electrical connection between the coupling portion 125 and the other electrical components.

[0105] In the embodiment of the present invention, Figure 4 As shown, the terminal block 120 may further include an elastic reinforcement portion 127 connected between the strain portion 126 and the mounting portion 122 to enhance the strain capacity of the strain portion 126 and reduce the probability of elastic failure of the strain portion 126 after deformation. The elastic reinforcement portion 127 may be in a bent V-shape and positioned closer to the mounting portion 122 relative to the coupling portion 125.

[0106] To improve the stability of the connection terminal 120 in the housing 110, in the embodiment of the present invention, at least two positioning holes 1222 can be provided on the mounting surface 1221 of each connection terminal, and corresponding positioning members are provided in the housing 110. A mismatch prevention design is provided between the at least two positioning holes 1222 and the corresponding at least two positioning members.

[0107] The housing 110 may include a docking plate 114, with the pressing opening 112 extending through the docking plate 114. At least two mutually insulated receiving slots are provided on the docking plate 114, extending through the interior and exterior of the housing 110. The coupling portions 125 of at least two wiring terminals 120 are respectively disposed within the at least two receiving slots, thereby achieving electrical connection between the coupling portions 125 and the external electrical system, thereby providing the receiving slots with electrical connection capability. Obviously, the number of wiring terminals 120 can be equal to the number of receiving slots; in some cases, the number of wiring terminals 120 can be greater than the number of receiving slots.

[0108] In order to enable relative rotation between the junction box 100 and the target object (such as the first main body 240 of the fixing base 200 provided in the embodiment below) when mechanically connecting the junction box 100 and the target object without affecting the electrical connection between the junction box and the target object, at least two receiving grooves on the junction box can be a rotating structure centered on a rotating shaft 10. The at least two receiving grooves can be arranged concentrically around the rotating shaft 10, such as Figure 1 As shown, the receiving slot ( Figure 1 The first receiving slot 1141, the second receiving slot 1142, and the third receiving slot 1143 can be circular or annular. As a variation, at least two receiving slots can be located on the same circumference of a rotating shaft 10, in which case the receiving slots are arc-shaped, and each receiving slot is the same distance from the rotating shaft 10. Obviously, to achieve effective electrical connection, the receiving slots are insulated from each other. When there are two receiving slots, the two receiving slots are the L pole and the N pole, respectively. When there are three receiving slots, the three receiving slots are the L pole, the ground pole, and the N pole, respectively. The three receiving slots correspond to the three wire inlets 111, respectively. Moreover, the three wire inlets 111 are also connected to the external wires of the L pole, the ground pole, and the N pole, respectively. In addition, the number of receiving slots can also be more than three, such as four, five, etc.

[0109] like Figure 1 As shown, three receiving grooves are shown from the outside to the inside of the docking plate 114, namely a first receiving groove 1141, a second receiving groove 1142 and a third receiving groove 1143.

[0110] The docking plate 114 is provided with a first, inwardly recessed receiving cavity. The inner wall of the first receiving cavity comprises a cylindrical first insulating portion of a certain height, a cylindrical second insulating portion disposed within the first insulating portion and parallel to and of the same height as the first insulating portion, and a cylindrical third insulating portion disposed within the second insulating portion and parallel to and of the same height as the second insulating portion. An annular first receiving groove 1141 is formed between the first and second insulating portions, an annular second receiving groove 1142 is formed between the second and third insulating portions, and a circular third receiving groove 1143 is disposed in the center of the third insulating portion.

[0111] The housing 110 may further include a sidewall 115, the extension surface of which is perpendicular to the mounting surface 1221 and may be mutually perpendicular to the extension surface of the docking plate 114. The junction box 100 includes a first detachable connection portion 117, which extends circumferentially and surrounds the sidewall 115 and is used to detachably connect the housing 110 to a target object.

[0112] The first detachable connection portion 117 includes an extension portion 1171 and a notch 1172. The extension portion 1171 is compressed from the sidewall 115 toward the inner wall of the housing 110, while the notch 1172 extends through the extension portion 1171 along the extension surface of the sidewall 115. The first detachable connection portion 117 may also include a beveled guide area 1173 and a fastening area 1174. The beveled guide area 1173 is disposed adjacent to the notch 1172 along the axis, and the fastening area 1174 smoothly engages with the beveled guide area 1173 in the circumferential direction. The fastening area 1174 is adapted to be clamped onto a target object, thereby achieving a detachable connection between the first detachable connection portion 117 and the target object.

[0113] When viewed in the axial direction, the notch 1172 can be a circumferential closed loop opening (ie, maintaining a distance from the outer edge of the extension portion 1171) or an open loop opening (ie, maintaining connection with the outer edge of the extension portion 1171). Figure 1 As shown, in order to improve the compactness of the structure, the gap 1172 in the embodiment of the present invention can be an open ring.

[0114] Housing 110 may further include a mounting plate 116, which is positioned opposite to press opening 112, with its extension perpendicular to the extension of housing sidewall 115. Mounting plate 116 includes an inner surface and an outer surface disposed opposite each other. The inner surface mates with mounting surface 1221 of terminal block 120, while the outer surface faces away from press opening 112, relative to first detachable connection portion 117. In other words, a step is formed between the outer surface and first detachable connection portion 117, facilitating pre-positioning of junction box 100 when mounted on a target object.

[0115] In an embodiment of the present invention, the terminal block 120 should be made of a conductive elastic material. The terminal block 120 can be integrally formed during the manufacturing process, such as by casting, or can be made in sections and then connected together. For example, the connecting plate 123, the wire abutment portion 121, and the positioning portion 124 in the terminal block 120 are made as a whole, and the mounting portion 122, the coupling portion 125, and the strain portion 126 are also made as a whole, and then the connecting portion is connected to the mounting portion 122 (such as by welding) to obtain the terminal block 120. In addition, the connecting plate 123, the wire abutment portion 121, and the positioning portion 124 can be made as a whole, the coupling portion 125 and the strain portion 126 can be made as a whole, and the mounting portion 122 can be a circuit board, thereby connecting the connecting plate 123 and the strain portion 126 to the circuit board respectively, and realizing the electrical connection between the connecting plate 123 and the strain portion 126.

[0116] Example 2

[0117] An embodiment of the present invention provides a lamp fixture 400, comprising a matching mounting base 200 and a connecting base 300. The mounting base 200 can be pre-installed on a mounting base such as a roof or ceiling, while the connecting base 300 is pre-installed in the lamp, thereby enabling quick and convenient connection of the lamp to a mounting base such as a roof or ceiling.

[0118] Figure 8 This is a structural diagram of the fixing base 200 in the lamp fixing device 400 provided in Example 2 of the present invention at a certain viewing angle. Figure 9 This is an exploded view of the fixing seat 200 from another perspective. Figure 10 is a structural diagram of the fixing base 200 from another perspective, Figure 11 This is a structural diagram of the matching of the fixing base 200 and the connecting base 300. Figure 12 Schematic diagram of the structure of the connecting socket 300 at one viewing angle. Figure 13 is an exploded view of the lighting device 600, Figure 14 is an axial cross-sectional view of the lighting device 600 along the rotation axis 10, wherein Figure 13 and Figure 14 In the lighting device 600, the size of the second outer edge portion 350 of the connecting seat 300 in the lamp body assembly 500 can be extended radially outward, thereby increasing the radial surface size of the connecting seat 300. Figure 13 and Figure 14 The radial dimension of the connecting seat 300 is significantly larger than Figures 8 to 12 The radial dimension of the connecting seat 300 is as follows: Figures 8-14 Introduce the relevant structures respectively.

[0119] like Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the first electrical connection portion 210 of the fixing base 200 can be embedded and connected with the second electrical connection portion 310 on the connection base 300, that is, the first electrical connection portion 210 and the second electrical connection portion 310 are matched with each other to achieve electrical connection. The first electrical connection portion 210 has at least two mutually insulated receiving grooves, each of which has a coupling portion 125 that can be electrically connected, such as two, three, or four or more. Correspondingly, the second electrical connection portion 310 also has at least two conductive terminals, such as two, three, or four or more, each of which is electrically connected to the coupling portion 125 in each receiving groove.

[0120] In the embodiments of the present invention, "extending in a certain direction" may refer to extending approximately in that direction or absolutely in that direction. Furthermore, the circumferential direction in this application refers to the circumferential direction of the fixing base 200, the connecting base 300, and the lamp fixture 400; the axial direction refers to the extending direction from the fixing base 200 to the connecting base 300 on the lamp fixture 400; and the radial direction refers to the direction perpendicular to the axial direction.

[0121] The fixing base 200 includes a first electrical connection portion 210 and a first coupling portion 220. The first coupling portion 220 is circumferentially arranged coaxially with the first electrical connection portion 210 around a rotation axis 10. The first coupling portion 220 includes at least two circumferentially arranged mounting slots 221. Each mounting slot 221 includes an open end 2211, a first engaging surface 2212, and a retaining structure 2213, which are sequentially arranged. The first engaging surface 2212 faces away from the connecting base 300 and connects the open end 2211 and the retaining structure 2213. The retaining structure 2213 extends along the axial surface. The mounting groove 221 is suitable for cooperating and connecting with the first protrusion 321 extending along the radial surface and arranged circumferentially on the connecting seat 300, wherein the limiting structure 2213 is used to limit the depth of the first protrusion 321 entering the first clamping surface 2212 from the opening end 2211, that is, to achieve limitation in one circumferential direction. The first clamping surface 2212 can be used for clamping to achieve axial positioning, thereby utilizing the mounting groove 221 to achieve mechanical connection between the fixing seat 200 and the connecting seat 300.

[0122] like Figure 10As shown, an elastic rib 22121 is provided on the first clamping surface 2212, and the elastic rib 22121 extends in the direction from the open end 2211 to the limiting structure 2213 and is arc-shaped, and the center of the arc is concentric with the center of at least two circumferentially arranged mounting grooves 221. Obviously, the center is collinear with the rotation axis 10 in Example 1. Thus, when the third coupling portion of the connecting seat 300 is coupled with the first coupling portion 220 of the fixing seat 200, they can rotate relative to each other around the rotation axis 10, and during the relative rotation process, since the first clamping surface 2212 has the elastic rib 22121, the first clamping surface 2212 and the second clamping surface 3211 can fit tightly together, thereby avoiding relative shaking between the fixing seat 200 and the connecting seat 300 after matching. As shown Figure 10 As shown, two elastic ribs 22121 may be provided on each first engaging surface 2212 .

[0123] In the embodiment of the present invention, at least two mounting grooves 221 are evenly distributed along a circumferential direction, and the number thereof can be two, three, four or more.

[0124] In the embodiment of the present invention, the fixing seat 200 may further include a second coupling portion 230. The second coupling portion 230 is provided along the circumferential direction and is at least used for performing a limiting connection in the circumferential direction.

[0125] The first coupling portion 220 is circumferentially disposed and located on the periphery of the first electrical connection portion 210. As a variation, the first electrical connection portion 210 may be circumferentially disposed on the periphery of the first coupling portion 220, or the first electrical connection portion 210 may be circumferentially surrounded between the first coupling portion 210 and the second coupling portion 230.

[0126] The fixing seat 200 may further include a first main body portion 240 and a first outer edge portion 250 . The first outer edge portion 250 surrounds the first main body portion 240 .

[0127] The fixing seat 200 may also include a first side wall 260, which surrounds the outer periphery of the first main body portion 240, and the first outer edge portion 250 surrounds the outer periphery of the first side wall 260. In other words, on the radial surface of the fixing seat 200, the first main body portion 240, the first side wall 260 and the first outer edge portion 250 are arranged in sequence from the center to the periphery.

[0128] In the embodiment of the present invention, the first coupling portion 220 can be disposed on the first main body portion 240, and the second coupling portion 230 can be disposed on the first outer edge portion 250. As a variation, both the first coupling portion 220 and the second coupling portion 230 can be disposed on the first main body portion 240, or both on the first outer edge portion 250, or the first coupling portion 220 can be disposed on the first outer edge portion 250, and the second coupling portion 230 can be disposed on the first main body portion 240. Furthermore, both the first coupling portion 220 and the second coupling portion 230 can be disposed circumferentially.

[0129] In an embodiment of the present invention, the first main body portion 240 may include a bottom end portion 241 extending along a radial surface. The bottom end portion 241 may be plate-shaped. The first sidewall 260 extends axially from the periphery of the bottom end portion 241 toward the connection base 300. Relative to the bottom end portion 241, the first electrical connection portion 210 is disposed adjacent to the connection base 300. The first coupling portion 220 may be disposed on the bottom end portion 241. As a variation, only the second coupling portion 230 may be disposed on the bottom end portion 241, or both the first coupling portion 220 and the second coupling portion 230 may be disposed simultaneously.

[0130] The second engaging portion 230 is provided circumferentially and is used at least for limiting the position in the circumferential direction opposite to the limiting structure 2213, i.e., it has a retreat prevention function. Therefore, the limiting structure 2213 and the second engaging portion 230 can limit the connection base 300 on the fixed base 200 in both the clockwise and counterclockwise directions along the circumferential direction. Furthermore, the second engaging portion 230 can also be used for limiting the position in the axial direction opposite to the first engaging surface 2212. That is, the first engaging surface 2212 and the second engaging portion 230 can limit the connection base 300 on the fixed base 200 in two opposite axial directions.

[0131] The second coupling portion 230 includes a fixed end 231 and a free end 232 which are arranged and connected in sequence along the circumferential direction. The fixed end 231 is fixedly connected to the fixing seat 200, and the free end 232 can move relative to the fixed end 231 in a direction away from the connecting seat 300 to apply an axial force to the connecting seat 300. The axial force is from the fixed end 231 toward the connecting seat 300, and a stop protrusion 2321 is provided on the surface of the free end 232 facing the connecting seat 300. The stop protrusion 2321 is used to prevent the second protrusion 331 of the connecting seat 300 from coming out in the opposite direction after being coupled with the second coupling portion 230, that is, to reduce the probability of the fixed seat 200 and the connecting seat 330 automatically moving in the opposite direction and separating after the two are assembled. In other words, it prevents the first protrusion 321 of the connecting seat 300 from automatically coming out of the mounting groove 221 in a direction opposite to the first direction after sliding into the mounting groove 221 in the first direction, that is, to limit the first protrusion 321.

[0132] To further prevent the first protrusion 321 of the connecting base 300 from automatically falling out of the mounting groove 221 in a direction opposite to the first direction after sliding into the mounting groove 221 in a first direction, a first engaging groove 2322 is further provided on the surface of the free end 232 facing the connecting base 300. The retaining protrusion 2321 is spaced away from the fixed end 231 relative to the first engaging groove 2322. The first engaging groove 2322 can engage with the first protrusion 321 of the connecting base 300, further achieving circumferential positioning of the connecting base 300 and the fixed base 200.

[0133] like Figure 8 As shown, the first sidewall 260 and the bottom end portion 241 surround and form a receiving cavity, in which the first electrical connector 210 can be disposed. The opening of the receiving cavity can face the connection base 300, and the bottom end portion 241 can be disposed away from the connection base 300 relative to the first electrical connector 210. For example, the first electrical connector 210 can be disposed on the surface of the bottom end portion 241 facing the connection base 300, and in the middle of the bottom end portion 241.

[0134] The first electrical connector 210 can be used to electrically connect to the second electrical connector 310 in the connector base 300. Furthermore, the mechanical connection between the first electrical connector 210 and the first main body 240 of the fixing base 200 can be either a fixed connection or a removable connection. The first electrical connector 210 can be the junction box 100 of Example 1 of the present invention. When the first electrical connector 210 is the junction box 100 of Example 1 of the present invention, to achieve a removable connection between the bottom end portion 241 and the junction box 100, the bottom end portion 241 should have a second removable connector 242. The second removable connector 242 is used to removably connect to the first removable connector 117 of the junction box 100.

[0135] In order to achieve a detachable connection between the first main body 240 and the junction box 100 , the structure of the second detachable connecting portion 242 of the present application and its connection method with the first detachable connecting portion 117 in Example 1 are described below.

[0136] In which, the second detachable connecting part 242 can include the above-mentioned bottom end part 241 and the claw 2421, the claw 2421 is arranged along the circumference of a rotating shaft 10 (the same as the rotating shaft 10 in Example 1), relative to the bottom end part 241, the claw 2421 is set close to the connecting seat 300, and a clamping gap 2422 is formed between the claw 2421 and the top end part 341, and the clamping gap 2422 is suitable for clamping the fastening area 1174 of the junction box 100.

[0137] like Figure 9As shown, the second detachable connection portion 242 may further include a stopper 2423, which extends axially and is positioned away from the centerline of the rotation axis 10 relative to the claw 2421. When connecting the junction box 100 of Example 1 of the present invention to the first main body 240 of the present application, the claw 2421 can be first axially aligned with the notch 1172 of the junction box 100 (the rotation axis 10 of the two are colinear). At this time, the outer edge of the extension portion 1171 of the first detachable connection portion 117 abuts the stopper 2423, so that the two are aligned in the circumferential direction. Then, the first detachable connection portion 117 is relatively rotated along the rotation axis 10, so that the inclined guide area 1173 and the fastening area 1174 of the first detachable connection portion 117 sequentially enter the clamping gap 2422, and the fastening area 1174 is clamped in the clamping gap 2422, thereby achieving a detachable connection between the first detachable connection portion 117 and the second detachable connection portion 242. Furthermore, because a step is formed between the outer surface of the housing of the junction box 100 and the first detachable connecting portion 117, a corresponding pre-positioning hole 243 is provided on the first main body 240. The pre-positioning hole 243 is sized to accommodate the step. This step and the pre-positioning hole 243 on the first main body 240 further facilitate pre-positioning of the junction box 100 and the first main body 240, thereby facilitating alignment of the two. The number of claws 2421 can be three, or more than three, such as four or five, and the number of notches 1172 can be equal to or different from the number of claws 2421.

[0138] When viewed along the axial direction of the junction box 100, the notch 1172 can be a circumferential closed loop opening (i.e., maintaining a distance from the outer edge of the extension portion 1171) or an open loop opening (i.e., maintaining a connection with the outer edge of the extension portion 1171). To improve the compactness of the structure, the notch 1172 in the embodiment of the present invention can also be an open loop opening. In this case, since the notch 1172 needs to match the claw 2421, the limiting baffle 2423 can naturally be arranged between two adjacent claws 2421 in order to abut against the outer edge of the extension portion 1171 of the housing in the junction box 100. As a result, the structure of the first detachable connecting portion 117 and the second detachable connecting portion 242 can be more compact. As a variation, the notch 1172 on the bottom end plate can also be a closed-loop notch 1172 when viewed axially, that is, it does not penetrate to the outer edge of the bottom end plate. At this time, since the notch 1172 and the claw 2421 need to be aligned and matched, the limit baffle 2423 naturally needs to maintain a distance from the claw 2421 in order to rest against the outer edge of the bottom end plate, and the limit baffle 2423 is arranged on the periphery of the claw 2421.

[0139] In the embodiment of the present invention, the arrangement of the limiting baffle 2423 can further improve the assembly efficiency between the first detachable connecting portion 117 and the second detachable connecting portion 242 .

[0140] Of course, the first detachable connecting portion 117 and the second detachable connecting portion 242 may not be structures as described above, such as a common screw connection structure.

[0141] As mentioned in Example 1, at least two receiving grooves can be provided on the docking plate 114 on the junction box 100 (i.e., on the end surface of the first electrical connection portion 210 facing the connection seat 300), and the at least two receiving grooves are insulated from each other and form a rotating structure centered on a rotating shaft 10.

[0142] There may be at least two receiving grooves arranged concentrically around the rotating shaft 10, such as Figure 1 As shown, the receiving groove can be circular or annular; as a variation, at least two receiving grooves can be located on the same circumference of a rotating shaft 10, then the receiving grooves are arc-shaped, and the distance from each receiving groove to the rotating shaft 10 is the same.

[0143] Obviously, in order to achieve effective electrical connection, the receiving slots are insulated from each other. When there are two receiving slots, the two receiving slots are the L pole and the N pole respectively; when there are three receiving slots, the three receiving slots are the L pole, the ground pole, and the N pole respectively. In addition, the number of receiving slots can also be three, such as four, five, etc.

[0144] For example, as in Example 1, the docking plate 114 of the junction box 100 (i.e., the end surface of the first electrical connection portion 210 facing the connection base 300) may include a first receiving groove 1141, a second receiving groove 1142 and a third receiving groove 1143 that are insulated from each other from the outside to the inside around the rotation axis 10, and each receiving groove has a coupling portion 125 of a wiring terminal. Correspondingly, the connection base 300 has a first conductive terminal 311, a second conductive terminal 312 and a third conductive terminal 313 from the outside to the inside.

[0145] As a variation, the first electrical connection portion 210 may be provided with a conductive terminal instead of a receiving groove, and the corresponding second electrical connection base 300 on the connection base 300 may be provided with a receiving groove instead of a conductive terminal.

[0146] The above describes the specific structure and connection method of the second detachable connecting portion 242 on the first combining portion 220 and the second detachable connecting portion 242 of the junction box 100 in the embodiment of the present invention. The following continues to describe the structure of other components in the fixing base 200 of the present application.

[0147] In an embodiment of the present invention, the limiting structure 2213 of the first coupling portion 220 extends from the bottom end portion 241 toward the surface of the connecting seat 300 in the direction of the connecting seat 300 (such as extending axially close to the connecting seat 300), and the first clamping surface 2212 extends circumferentially from the end surface of the limiting structure 2213 close to the connecting seat 300, and relative to the bottom end portion 241, the first clamping surface 2212 is arranged close to the connecting seat 300.

[0148] The bottom end portion 241 also has a first wire-passing hole 2411. The first wire-passing hole 2411 is axially extending and can be located between the first electrical connection portion 210 and the first coupling portion 220. External wires pass through the side of the bottom end portion 241 facing away from the connection base 300 and into the middle accommodating cavity, electrically connecting to the junction box 100 located therein to provide power to the junction box 100. Of course, as a variation, the first wire-passing hole 2411 can be located elsewhere rather than between the first electrical connection portion 210 and the first coupling portion 220. The specific location can be flexibly set as needed, as long as it can achieve the wire-passing function and meet safety regulations.

[0149] The first outer edge portion 250 extends radially, and the first sidewall 260 has an axial guide portion 261 extending axially. To achieve the guiding function of the axial guide portion 261, the axial guide portion 261 should be closer to the connecting seat 300 than the bottom end portion 241 and the first outer edge portion 250. Therefore, the axial guide portion 261 is farther away from the bottom end portion 241 than the first outer edge portion 250.

[0150] The axial guide portion 261 can be used to guide the fixing seat 200 and the connecting seat 300 to be aligned when they are matched, and then rotate the connecting seat 300 relative to the fixing seat 200 to achieve the matching connection between the fixing seat 200 and the connecting seat 300.

[0151] The fixing base 200 also has mounting holes 270. These mounting holes 270 can be axially disposed on the first main body 240 and located within the inner circle of the first coupling portion 220, that is, closer to the circumferential center of the first main body 240 than the first coupling portion 220. The number of mounting holes 270 can be three, four, or more, and they can be evenly distributed along the circumference. Of course, as a variation, the mounting holes 270 can also be disposed not on the first main body 240, but on the first outer edge portion 250, or on the periphery of the first outer edge portion 250.

[0152] The first electrical connection portion 210 may be located on the first main body portion 240 and may be located on the inner circle of the first coupling portion 220 . In some special cases, it may be located on the first outer edge portion 250 .

[0153] The fixing base 200 according to the embodiment of the present invention is introduced above. The connecting base 300 matching with the fixing base 200 is introduced below in combination with the fixing base 200 .

[0154] like Figure 11 and Figure 12 As shown, the connecting base 300 includes a second electrical connecting portion 310 and a third combining portion. The third combining portion is arranged along the axis and is coaxially arranged with the second electrical connecting portion 310 around a rotation axis. The third combining portion includes a first protrusion 321. At least two first protrusions 321 are arranged along the axis and protrude toward the fixing base 200. The first protrusion 321 includes a second clamping surface 3211. The second clamping surface 3211 faces away from the fixing base 200. The first protrusion 321 is suitable for sliding into or out of the mounting groove 221 of the fixing base 200 through the open end 2211 of the fixing base 200, and the sliding depth is limited by the limiting structure 2213 so that the second clamping surface 3211 cooperates with the first clamping surface 2212.

[0155] In the embodiment of the present invention, the connecting seat 300 may further include a fourth coupling portion, which is circumferentially arranged for mating and coupling with the second coupling portion 230 of the fixing seat 200 . The fourth coupling portion may include a second protrusion 331 .

[0156] The connection base 300 may include a second main body portion 340 , on which a third combining portion and a second electrical connection portion 310 may be disposed.

[0157] The connecting seat 300 may further include a sleeve groove 360 ​​. The sleeve groove 360 ​​is circumferentially arranged around the second main body portion 340 and is used for sleeve connection with the axial guide portion 261 of the fixing seat 200 .

[0158] In this embodiment of the present invention, the connector 300 may further include a second outer edge portion 350, which surrounds the outer circumference of the sleeve groove 360. The third and fourth coupling portions may be disposed on the second main body portion 340, or on the second outer edge portion 350, or one of them may be disposed on the second main body portion 340 and the other on the second outer edge portion 350. In this embodiment of the present invention, the third coupling portion is disposed on the first main body portion 240, and the fourth coupling portion is disposed on the second outer edge portion 350.

[0159] The second main body 340 further includes a top portion 341 extending along a radial surface. A sleeve groove 360 ​​is disposed on the periphery of the top plate, with the notch of the sleeve groove 360 ​​facing the fixing base 200. The third coupling portion can be connected to the top portion 341. The second electrical connection portion 310 is disposed away from the fixing base 200 relative to the top portion 341. As a variation, a fourth coupling portion can also be disposed on the top portion 341.

[0160] The second outer edge portion 350 extends along a radial surface, and when the fourth coupling portion includes the second protrusion 331, it can be circumferentially disposed on a surface of the second outer edge portion 350 facing the fixed seat 200. The second outer edge portion 350 of the connecting seat 300 is substantially aligned with the first outer edge portion 250 of the fixed seat 200 in the axial direction, so that the second protrusion 331 on the second outer edge portion 350 can couple with the second coupling portion 230 on the first outer edge portion 250. After the connecting base 300 and the fixing base 200 are sleeved together, the second protrusion 331 can rotate relative to the fixing base 200 when the connecting base 300 is driven by an external force. The second protrusion 331 rotates onto the free end 232 of the second engaging portion 230. The free end 232 deforms relative to the fixed end 231 and exerts an elastic force on the second protrusion 331 from the fixing base 200 toward the connecting base 300. This elastic force causes the first engaging surface 2212 and the second engaging surface 3211 to abut against each other, thereby achieving axial fixation between the fixing base 200 and the connecting base 300. Furthermore, the stop protrusion 2321 on the free end 232 prevents the second protrusion 331 from automatically disengaging from the second engaging portion 230.

[0161] The second electrical connection portion 310 may be located on the second main body portion 340 and located on the inner circle of the third connecting portion. In some special cases, the second electrical connection portion 310 may be located on the second outer edge portion 350 .

[0162] like Figure 8 、 Figure 12 、 Figure 13 and Figure 14 As shown, to achieve electrical connection between the fixing base 200 and the connecting base 300, the second electrical connection portion 310 is disposed toward the fixing base 200 and includes a first conductive terminal 311, a second conductive terminal 312, and a third conductive terminal 313, which are sequentially distributed from the outside to the inside. When the first coupling portion 220 of the fixing base 200 is connected to the third coupling portion of the connecting base 300, the first conductive terminal 311, the second conductive terminal 312, and the third conductive terminal 313 are respectively received in the first receiving groove 1141, the second receiving groove 1142, and the third receiving groove 1143, thereby achieving electrical connection between the first electrical connection portion 210 of the fixing base 200 and the second electrical connection portion 310 of the connecting base 300.

[0163] The first and second conductive terminals 311, 312 are metal rings that match the size and shape of the first and second receiving slots 1141, 1142, respectively. The third conductive terminal 313 is a metal pin that matches the size and shape of the third receiving slot 1143. Of course, all the conductive terminals on the connector 300 can be metal rings. Furthermore, the first, second, and third conductive terminals 311, 312, and 313 are insulated from each other and form a rotating structure centered around a rotating axis 10, meaning they can be concentric circles. Of course, a concentric circle structure is also possible when there are two conductive terminals.

[0164] As a variation, the conductive terminals on the connecting base 300 can be distributed along the same circumference of the rotating shaft 10. In this case, the conductive terminals can all be metal pins, and the corresponding receiving grooves can be arc-shaped, so that at least two conductive terminals can rotate relative to each other after being inserted into the receiving grooves. Of course, this electrical connection method will reduce the relative rotation angle between the connecting base 300 and the fixing base 200 as the number of conductive terminals increases.

[0165] The lamp fixture device 400 provided in the embodiment of the present invention is applicable to a lamp body with a radial dimension less than 550 mm.

[0166] like Figure 13 and Figure 14 As shown, the connecting base 300 is connected to the lamp body to form a lamp body assembly 500, and the lamp body assembly 500 is matched with the fixing base 200 to form a lighting device 600. In addition, the lamp body assembly 500 can seal the light distribution element 513 or the lampshade with the light source module 512 and the power module 511. The sealed cover can ensure that the light distribution element 513 or the lampshade can non-detachably cover the light source module 512 and the power module 511, preventing foreign objects such as mosquitoes from entering the light source cavity and affecting light emission.

[0167] Example 3

[0168] The above-mentioned embodiment 2 provides a lamp fixing device 400, and embodiment 3 of the present invention provides another lamp fixing device 400, including a fixing base 200 and a connecting base 300 used in pair, wherein the fixing base 200 can be pre-installed on an installation base such as a roof or ceiling, and the connecting base 300 is pre-installed in the lamp, thereby enabling the lamp to be quickly and conveniently connected to an installation base such as a roof or ceiling.

[0169] Figure 15 Schematic diagram of the structure of the fixing base 200 of the lamp fixing device 600 in embodiment 3 of the present invention at a certain viewing angle, Figure 16 for Figure 15 A schematic structural diagram of the middle fixing seat 200 from another perspective, Figure 17Schematic diagram of the structure of the connecting base 300 of the lamp fixing device 400 in embodiment 3 of the present invention at one viewing angle. Figure 18 FIG. 3 is a structural diagram of an illuminating device 600 including a fixing base 200 and a lamp body assembly 500 in Example 3 of the present invention. Figure 19 This is an axial cross-sectional view of the lighting device 600 along the rotation axis 10 in Example 3 of the present invention. Figure 18 and Figure 19 The radial dimension of the connecting seat 300 is significantly larger than Figure 15-17 The radial dimension of the connecting base 300 is because the second outer edge portion 350 of the connecting base 300 in the lighting device 600 can be extended radially outward as needed. Figures 15-19 Introduce the relevant structures respectively.

[0170] like Figure 15 and Figure 16 As shown, the first electrical connection portion 210 of the fixing base 200 can be embedded and connected with the second electrical connection portion 310 on the connecting base 300. That is, the first electrical connection portion 210 and the second electrical connection portion 310 are electrically connected by a concave-convex fit. The first electrical connection portion 210 has at least two mutually insulated receiving grooves, such as two, three, or four or more. Correspondingly, the second electrical connection portion 310 also has at least two conductive terminals, such as two, three, or four or more. Each conductive terminal is electrically connected to the coupling portion 125 in each receiving groove.

[0171] In the embodiments of the present invention, "extending in a certain direction" may refer to extending approximately in that direction or absolutely in that direction. Furthermore, the circumferential direction in this application refers to the circumferential direction of the fixing base 200, the connecting base 300, and the lamp fixture 400, and the axial direction refers to the extending direction from the fixing base 200 to the connecting base 300 on the lamp fixture 400, from the radial direction to the direction perpendicular to the axial direction.

[0172] The fixing base 200 includes a first electrical connection portion 210 and a first coupling portion 220. The first coupling portion 220 is arranged circumferentially and coaxially with the first electrical connection portion 210 around the rotation axis 10. The first coupling portion 220 includes at least two circumferentially arranged mounting slots 221. Each mounting slot 221 includes an open end 2211, a first engaging surface 2212, and a retaining structure 2213, which are sequentially arranged. The first engaging surface 2212 faces away from the connecting base 300 and connects the open end 2211 and the retaining structure 2213. The retaining structure 2213 extends along the axial surface. The mounting groove 221 is suitable for cooperating and connecting with the first protrusion 321 extending along the radial surface and arranged circumferentially on the connecting seat 300, wherein the limiting structure 2213 is used to limit the depth of the first protrusion 321 entering the first clamping surface 2212 from the opening end 2211, that is, to achieve limitation in one circumferential direction. The first clamping surface 2212 can be used for clamping to achieve axial positioning, thereby utilizing the mounting groove 221 to achieve mechanical connection between the fixing seat 200 and the connecting seat 300.

[0173] In the embodiment of the present invention, at least two mounting grooves 221 are evenly distributed along a circumferential direction, and the number thereof can be two, three, four or more.

[0174] The fixing seat 200 may further include a second coupling portion 230 , which is provided along the circumferential direction and is at least used to limit the circumferential position between the fixing seat 200 and the connecting seat 300 .

[0175] The first coupling portion 220 is circumferentially disposed and located on the periphery of the first electrical connection portion 210. As a variation, the first electrical connection portion 210 may be circumferentially disposed on the periphery of the first coupling portion 220, or the first electrical connection portion 210 may be circumferentially surrounded between the first coupling portion 210 and the second coupling portion 230.

[0176] The fixing seat 200 may include a first main body portion 240 and a first outer edge portion 250 surrounding an outer circumference of the first main body portion 240 .

[0177] The fixing base 200 may further include a first sidewall 260, which surrounds the outer periphery of the first main body 240. The first outer edge 250 is disposed around the first sidewall 260. In other words, the first main body 240, the first sidewall 260, and the first outer edge 250 are disposed sequentially from the center to the periphery on the radial surface of the fixing base 200. The first outer edge 250 is disposed closer to the connecting base 300 than the first main body 240.

[0178] In the embodiment of the present invention, the first coupling portion 220 may be disposed on the second outer edge portion 350, and the second coupling portion 230 may be located on the second main body portion 340. As a variation, the first coupling portion 220 and the second coupling portion 230 may both be located on the second outer edge portion 350, or both be located on the second main body portion 340, or the first coupling portion 220 and the second coupling portion 230 may be located on the second outer edge portion 350.

[0179] The first main body 240 further includes a bottom end 241 extending along a radial surface. The first coupling portion 220 can be connected to the bottom end 241. The first electrical connection portion 210 is disposed adjacent to the connection base 300 relative to the bottom end 241. For example, the bottom end 241 is annular in shape, and the first electrical connection portion 210 can be disposed in the annular shape.

[0180] The second coupling portion 230 is provided circumferentially and is used at least for limiting the position in the circumferential direction opposite to the limiting structure 2213, i.e., it has a retreat prevention function. Therefore, the limiting structure 2213 and the second coupling portion 230 can limit the connection base 300 on the fixing base 200 in both the clockwise and counterclockwise directions along the circumferential direction. Moreover, the second coupling portion 230 can also be used for limiting the position in the axial direction opposite to the first engaging surface 2212. That is, the first engaging surface 2212 and the second coupling portion 230 can limit the connection base 300 on the fixing base 200 in two opposite axial directions.

[0181] Among them, the second coupling portion 230 includes a fixed end 231 and a free end 232 arranged in sequence along the circumferential direction and connected. The fixed end 231 is fixedly connected to the fixed base 200, and the free end 232 can move relative to the fixed end 231 in a direction away from the connecting base 300 to apply an axial force to the connecting base 300. The axial force is from the fixed end 231 toward the connecting base 300, and a stop protrusion 2321 is provided on the surface of the free end 232 facing the connecting base 300. The stop protrusion 2321 is used to prevent the first protrusion 321 of the connecting base 300 from sliding into the mounting groove 221 along the first direction and then automatically falling out of the mounting groove 221 in a direction opposite to the first direction, that is, to limit the first protrusion 321.

[0182] In an embodiment of the present invention, the limiting structure 2213 of the first coupling portion 220 extends from the bottom end portion 241 toward the surface of the connecting seat 300 in the direction of the connecting seat 300 (such as extending axially close to the connecting seat 300), and the first clamping surface 2212 extends circumferentially from the end surface of the limiting structure 2213 close to the connecting seat 300, and relative to the bottom end portion 241, the first clamping surface 2212 is arranged close to the connecting seat 300.

[0183] In an embodiment of the present invention, the first coupling portion 220 may further include a stop portion 2214, which is provided on a protruding surface 2212 and can be aligned with the opening end 2211 in the axial direction, and is used to stop the connecting seat 300 connected to the fixed seat 200 together with the stop protrusion 2321 of the second coupling portion 230, to prevent the stop protrusion 2321 from automatically detaching from the opening end 2211 after entering the first clamping surface 2212.

[0184] As mentioned above, the bottom end portion 241 can be annular (in the axial direction), and the first electrical connection portion 210 includes an electrical shell 211 and an electrical component 212. The opening of the electrical shell 211 faces away from the connection base 300 and is flush with the bottom end portion 241. The electrical component 212 is arranged in the electrical shell 211. The electrical shell 211 can be integrally provided with the bottom end portion 241. The integral provision includes integral molding during the manufacturing process, or integral connection after separate manufacturing. The first electrical connection portion 210 can also include an electrical cover 213, which covers the opening of the electrical shell 211 and is flush with the bottom end portion 241. It can be understood that in this application, since the electrical shell 211 and the bottom end portion 241 are integrally provided, it is a variation of the embodiment in which the shell and the bottom end portion 241 of the junction box 100 are integrally provided. In some embodiments, the opening of the electrical housing 211 may not be flush with the bottom end portion 241 but may be staggered. Similarly, the electrical cover 213 may not be flush with the bottom end portion 241 but may be staggered.

[0185] In this embodiment of the present invention, the electrical cover 213 is provided with a second wire hole 2131 extending axially therethrough to electrically connect the electrical components 212 within the electrical housing 211 to external wires outside the electrical housing 211. The number of the second wire holes 2131 can be two, three, four, or more.

[0186] In this embodiment of the present invention, the fixing base 200 further includes mounting holes 270. These mounting holes 270 can be arranged along the axis and located on the periphery of the first outer edge portion 250, for example, on the periphery of the second coupling portion 230. The number of mounting holes 270 can be three, four, or more, and can be evenly distributed along the circumference. Of course, the mounting holes 270 can also be arranged not on the periphery of the first outer edge portion 250, but on the first outer edge portion 250 or on the first main body portion 240.

[0187] The first electrical connection portion 210 may include, from the outside to the inside, a first receiving groove 1141, a second receiving groove 1142, and a third receiving groove 1143, which are insulated from each other. These receiving grooves are obviously provided through the electrical housing 211. Each receiving groove contains a coupling portion 125 of a terminal block. Correspondingly, the connection base 300 may include, from the outside to the inside, a first conductive terminal 311, a second conductive terminal 312, and a third conductive terminal 313.

[0188] The fixing base 200 according to the third embodiment of the present invention is introduced above. The connecting base 300 matching the fixing base 200 according to the third embodiment of the present invention is introduced below in combination with the fixing base 200 .

[0189] like Figure 17 As shown, the connecting seat 300 includes a second electrical connecting portion 310 and a third combining portion, the third combining portion is arranged along the axis and is coaxially arranged with the second electrical connecting portion 310 around the rotating axis 10, the third combining portion includes a first protrusion 321, at least two first protrusions 321 are arranged along the axis and protrude toward the fixing seat 200, the first protrusion 321 includes a second clamping surface 3211, the second clamping surface 3211 is facing away from the fixing seat 200, the first protrusion 321 is suitable for sliding into or out of the mounting groove 221 of the fixing seat 200 through the open end 2211 of the fixing seat 200, and the sliding depth is limited by the limiting structure 2213 so that the second clamping surface 3211 is abutted against the first clamping surface 2212.

[0190] In the embodiment of the present invention, the connecting base 300 may further include a fourth coupling portion, which is arranged along the circumference and is configured to mate with the second coupling portion 230 of the fixing base 200. The fourth coupling portion may include a second engaging groove 332, and at least two second engaging grooves 332 are provided on the top portion 341 and located on the inner circle of the first protrusion 321.

[0191] The third connecting portion is circumferentially disposed and located outside the second electrical connection portion 310. Alternatively, the second electrical connection portion 310 may be circumferentially disposed outside the fourth connecting portion, or the second electrical connection portion 310 may be circumferentially disposed between the third and fourth connecting portions.

[0192] After the fixed base 200 and the connecting base 300 are aligned, they rotate relative to each other about the rotation axis 10. The retaining protrusion 2321 on the second engaging portion 230 of the fixed base 200 slides into the second engaging groove 332, thereby achieving circumferential restraint between the fixed base 200 and the connecting base 300. Furthermore, the free end 232 of the second engaging portion 230 deforms, exerting an axial elastic force on the connecting base 300. The second engaging groove 332 may be provided on the surface of the top portion 341 facing the fixed base 200, rather than passing through the top portion 341.

[0193] The connection base 300 may include a second main body portion 340 , on which a third combining portion and a second electrical connection portion 310 may be disposed.

[0194] The connector 300 may further include a second outer edge portion 350, which surrounds the outer circumference of the second main body portion 340. The second main body portion 340 may further include a top portion 341, which extends radially. The third coupling portion may also be disposed on the second outer edge portion 350 and radially connected to the top portion 341. The second electrical connector 310 is disposed away from the fixing base 200 relative to the top portion 341.

[0195] When the locking cam 331 is in the unlocked position, the locking cam 331 is in the unlocked position, and the locking cam 331 is in the unlocked position, so that the user can lock the locking cam 331. When the fixing base 200 and the connecting base 300 need to be separated, the connecting base 300 is rotated in the opposite direction to that of the mating connection. The user can also hear a click sound when the retaining protrusion 2321 slides out of the second engaging groove 332 .

[0196] The second electrical connection portion 310 may be located on the second main body portion 340 and located on the inner circle of the third connecting portion. In some special cases, the second electrical connection portion 310 may be located on the second outer edge portion 350 .

[0197] In addition, in the lamp fixture 400 of embodiment 3 of the present invention, the structures including the receiving grooves and conductive terminals on the first electrical connection part 210 and the second electrical connection part 310 can refer to the structures of the receiving grooves and conductive terminals in embodiment 2 of the present invention, and will not be repeated here.

[0198] The lamp fixture device 400 provided in the embodiment of the present invention is applicable to a lamp body with a radial dimension greater than 650 mm.

[0199] like Figure 18 and Figure 19As shown, the connecting base 300 is connected to the lamp body to form a lamp body assembly 500, and the lamp body assembly 500 is matched with the fixing base 200 to form a lighting device 600. In addition, the lamp body assembly 500 can seal the light distribution element 513 or the lampshade with the light source module 512 and the power module 511. The sealed cover can ensure that the light distribution element 513 or the lampshade can non-detachably cover the light source module 512 and the power module 511, preventing foreign objects such as mosquitoes from entering the light source cavity and affecting light emission.

[0200] Example 4

[0201] Embodiment 4 of the present invention provides a lamp fixture device 400, which is a further limitation of the lamp fixture device 400 in Embodiment 2, and may not have the first electrical connection part 210 in Embodiment 2, or have an electrical structure different from the first electrical connection part 210 in Embodiment 2.

[0202] The fourth embodiment of the present invention further describes in detail the first combining portion 220 and the second combining portion 230 in the fixing base 200 and the third combining portion and the fourth combining portion in the connecting base 300 .

[0203] The mounting groove 221 in the first coupling portion 220 includes an open end 2211 , a first engaging surface 2212 and a limiting structure 2213 sequentially arranged along a circumferential direction, and the circumferential direction is the same as the direction in which the fixing seat 200 rotates relative to the connecting seat 300 .

[0204] In addition, the first coupling portion 220 may further include a sliding opening 222, which extends circumferentially (around the rotating axis 10), is coaxially arranged with the first clamping surface 2212 and radially connects the first clamping surface 2212 and the accommodating cavity, as well as connects the opening end 2211 and the limiting structure 2213. Thus, when the connecting seat 300 is close to the accommodating cavity of the fixed seat 200, in order to connect the two, during the process of the connecting seat 300 rotating around the fixed seat 200 along the rotating axis 10, the first protrusion 321 on the connecting seat 300 slides from the open end 2211 along the sliding opening 222 until the first protrusion 321 abuts the limiting structure 2213, thereby allowing the fixed seat 200 and the connecting seat 300 to be more reliably connected together with the aid of the first coupling portion 220 and the third coupling portion. Of course, as a variation, the first coupling portion 220 may not have the sliding opening 222 , and the sliding travel of the first protrusion 321 in the mounting groove 221 is limited, thereby limiting the coupling strength between the first coupling portion 220 and the third coupling portion.

[0205] like Figure 10 As shown, the sliding opening 222 can be provided on the periphery of the first clamping surface 2212. Figure 12As shown, the first protrusion 321 on the connection seat 300 may extend radially inward from the inner ring sidewall 342. Furthermore, the first protrusion 321 on the connection seat 300 may be flush with the inner ring sidewall 342 in the radial direction.

[0206] The second coupling portion 230 on the fixing base 200 has a free end 232. In order to improve the deformation capability of the free end 232, as shown in FIG. Figure 8 As shown, a plurality of deformation enhancement holes 2323 can be provided on the surface of the free end 232 facing the connection seat. The deformation enhancement holes 2323 can be blind holes or through holes. Specifically, the deformation enhancement holes 2323 can be provided on the first card slot 2222.

[0207] In order to properly guide the first protrusion 321 of the connecting seat 300 , a transition slope area 2215 is further included between the opening end 2211 and the first docking surface 2212 . Obviously, the transition slope area 2215 is located between the opening end 2211 and the elastic rib 22121 .

[0208] The following introduces the connecting base 300 that is matched with the fixing base 200. The connecting base 300 is a further limitation of the connecting base 300 in Example 2.

[0209] The second main body portion 340 may include an inner sidewall 342, and the second outer edge portion 350 may include an outer sidewall 351. Both outer sidewall 351 and outer sidewall 342 extend axially and surround a sleeve groove 360. The first protrusion 321 may extend radially inward from the inner sidewall 342, while the second protrusion 331 may extend axially from the outer sidewall 351 toward the fixing seat 200.

[0210] Example 5

[0211] Embodiment 5 of the present invention provides a lamp fixture device 400, which is a further limitation of the lamp fixture device 400 in Embodiment 3, and may not have the first electrical connection part 210 in Embodiment 3, or have an electrical structure different from the first electrical connection part 210 in Embodiment 3.

[0212] Embodiment 5 of the present invention further details the first and second coupling portions 220 and 230 of the fixing base 200, and the third and third coupling portions of the connecting base 300. Since the lamp fixture device 400 of Embodiment 5 of the present invention can be a variation of Embodiment 4, the following mainly describes the differences from Embodiment 4.

[0213] like Figure 16As shown, the first engaging surface 2212 is disposed on the outer periphery of the sliding opening 222. Accordingly, the first protrusion 321 on the connecting seat 300 may be connected to the first main body portion 240 (the bottom end portion 241), specifically, radially connected to the outer periphery of the first main body portion 240, and the orthographic projection of the first protrusion 321 along the axial direction is located at the first outer edge portion 250.

[0214] As a result, the first engaging surface 2212 is located at the outer end of the sliding opening 222. At this time, the axial projection of the opening end 2211, the first engaging surface 2212, and the limiting structure 2213 can not overlap with the first main body 240. As a result, the opening end 2211 is not located in the accommodation space formed by the bottom end 241 and the first sidewall 260. In other words, the first coupling portion 220 is not located on the first main body 240, but on the first outer edge portion 250. In order to allow the first protrusion 321 of the connecting seat 300 to enter the installation groove 221, the first coupling portion 220 also includes a guide opening 223. The guide opening 223 is arranged axially through and is located on the same circumference as the installation groove 221. Relative to the limiting structure 2213, the guide opening 223 is arranged near the opening end 2211 and is connected to the opening end 2211. The first protrusion 321 of the connecting seat 300 is axially aligned with the guide opening 223 and approaches the fixing seat 200. After the first protrusion 321 and the opening end 2211 are located in the same radial plane, the connecting seat 300 is rotated, and the first protrusion 321 rotates along the sliding opening 222 and abuts against the limiting structure 2213.

[0215] Furthermore, the stopper 2214 is positioned away from the connector 300 relative to the first engaging surface 2212. Furthermore, the axial dimension of the stopper 2214 gradually decreases from the first engaging surface 2212 toward the open end 2211. The stopper 2214 may be wedge-shaped, with the tip of the wedge facing the open end 2211.

[0216] The following introduces the connecting base 300 that is matched with the fixing base 200. The connecting base 300 is a further limitation of the connecting base in Example 3. The difference between the connecting base 300 in this embodiment and the connecting base 300 in Example 4 is that the axial projection of the first protrusion 321 of the connecting base 300 is located on the second outer edge portion 350, and is radially connected to the second main body portion 340, specifically, it can be connected to the top portion 341.

[0217] There may be at least two first protrusions 321 , which are evenly distributed along the circumference.

[0218] Example 6

[0219] Embodiment 6 of the present invention provides a connection socket 300 , which may be a further definition of the connection socket 300 in Embodiment 2 of the present invention, or a further definition of the connection socket 300 in Embodiment 3 of the present invention.

[0220] like Figure 11 and Figure 12 ,or Figure 17 As shown, embodiment 6 of the present invention provides a connecting base 300 for connecting with a fixing base 200 that can be set on a mounting base. The connecting base 300 includes a top portion 341 and a second electrical connecting portion 310. Relative to the top portion 341, the second electrical connecting portion 310 is set away from the fixing base 200, and the top portion 341 can be set relative to the bottom end portion 241 on the fixing base 200. At the same time, the second electrical connecting portion 310 and the first electrical connecting portion 210 are embedded in each other to achieve electrical connection. The connecting base 300 also includes a power supply accommodating chamber, which is arranged on the side of the top portion 341 away from the fixing base 200. The power supply accommodating chamber for accommodating the power module 511 is at a height position equivalent to that of the second electrical connecting portion 310 in the axial direction. Therefore, compared with the connecting base 300 stacked with the power supply housing cavity and the second electrical connection part 310, the thickness of the connecting base 300 in the embodiment of the present invention can be thinner, thereby solving the problem of the thicker thickness after the fixing base 200 and the connecting base 300 are set in the lighting device 600, and realizing the lightweight and thinness of the connecting base 300, the lamp body assembly 500, the lamp fixing device 400 and the lighting device 600.

[0221] In order to further achieve lightness and thinness, the connecting base 300 may include a light source receiving cavity, and the light source receiving cavity and the power supply receiving cavity are at the same height in the axial direction.

[0222] The connecting base 300 may further include a second main body portion 340 and a second outer edge portion 350 . The second outer edge portion 350 is disposed on the outer periphery of the second main body portion 340 .

[0223] The light source receiving chamber can be provided on the second outer edge portion 350, and the power supply receiving chamber can be provided on the second main body portion 340. Since the power supply receiving chamber is provided on the side of the top portion 341 facing away from the fixing base 200, the power supply receiving chamber is also provided on the top portion 341. In other words, the second main body portion 340 includes the top portion 341. As a variation, the light source receiving chamber can be provided on the second main body portion 340. In this case, the second outer edge portion 350 includes the top portion 341, and the power supply receiving chamber is provided on the side of the top portion 341 facing away from the fixing base 200. That is, the power supply receiving chamber is provided on the side of the top portion 341 facing away from the fixing base 200, and the power supply receiving chamber is provided on the second outer edge portion 350. As another variation, the light source receiving cavity may also be arranged on the side of the top portion 341 away from the fixing seat 200. Obviously, the top portion 341 may belong to the second main body portion 340 or the second outer edge portion 350, that is, the light source receiving cavity and the power supply receiving slot may be located on the second main body portion 340 or on the second outer edge portion 350 at the same time.

[0224] In order to achieve a mechanical connection between the connecting base 300 and the fixing base 200, the connecting base 300 may further include a third coupling portion. The connecting base 300 may include a third coupling portion, which may be disposed on the second main body portion 340 or the second outer edge portion 350. The second main body portion 340 may include a top portion 341. The third coupling portion may be disposed closer to the fixing base 200 relative to the top portion 341 to facilitate mechanical connection between the third coupling portion and the first coupling portion 220 on the fixing base 200. The third coupling portion may be disposed on the second main body portion 340, for example, on a side of the top portion 341 facing the fixing base 200 and disposed toward the fixing base 200 (corresponding to the fixing base 200 of the above-mentioned embodiment 2). The third coupling portion may also be disposed on the second outer edge portion 350 and radially connected to the top portion 341 (corresponding to the fixing base 200 of the above-mentioned embodiment 3).

[0225] As a variation, the connector 300 may not include the second outer edge portion 350. Instead, the lamp housing of the lamp body may be connected to the second main body portion 340 of the connector 300. The lamp housing is disposed in an annular shape surrounding the second main body portion 340, and a light source receiving cavity is provided on the lamp body. Of course, the light source receiving cavity, the power supply receiving cavity, and the second electrical connection portion 310 are still positioned at the same height in the axial direction. Furthermore, the light distribution element 513 is sealingly connected to the edge of the lamp housing of the lamp body, thereby sealing the light source module 512, the power supply module 511, and the second electrical connection portion 310 within the space enclosed by the light distribution element 513 and the lamp housing.

[0226] Therefore, in an embodiment of the present invention, the light source accommodating cavity, the voltage accommodating cavity and the second electrical connection part 310 are all arranged at positions with equivalent axial heights on the connecting seat 300, thereby effectively controlling the thickness size after the light source module 512 and the power module 511 are arranged on the connecting seat 300, so as to achieve the purpose of lightness and thinness.

[0227] In order to make the structure of the connecting base 300 compact, the height positions of the conductive terminals on the connecting base 300 are the same; correspondingly, the depth positions of the receiving grooves on the fixing base 200 are the same.

[0228] Furthermore, an embodiment of the present invention further provides a lamp assembly 500 , which includes the aforementioned connection base 300 and a lamp body. The lamp body may have a power module 511 , which may be accommodated in a receiving cavity on the connection base 300 .

[0229] To achieve more effective weight reduction, the end surface of the power module 511 facing away from the fixing base 200 can be flush with the end surface of the second electrical connection portion 310 facing away from the fixing base 200. Alternatively, the end surface of the power module 511 close to the fixing base 200 can be flush with the end surface of the second electrical connection portion 310 close to the fixing base 200. In other words, the power module 511 can be flush with the second electrical connection portion 310 in the radial plane.

[0230] A light source module 512 is also provided on the lamp body. The light source module 512 includes a light source board and a light-emitting unit. The light source module 512 is arranged in the light source receiving cavity, and the light-emitting unit is facing away from the fixing seat 200. The light source board can be attached to the second main body part 340, thereby quickly dissipating the heat of the light source module 512 through the second main body part 340.

[0231] The lamp body may further include a light distribution element 513, which houses the power module 511, the light source module 512, and the second electrical connection portion 310 and is connected to the edge of the second outer edge portion 350 of the connector 300. This connection may be a sealed connection, where the light distribution element 513 seals the light source module 512, the power module 511, and the second electrical connection portion 310, thereby preventing mosquitoes from flying into the light source housing cavity and affecting the light distribution effect. The light distribution element 513 may be a lampshade, a diffuser, or the like.

[0232] Obviously, in the lamp fixture device 400 having the aforementioned connecting base 300, the first electrical connection portion 210 of the fixing base 200 is connected to the second electrical connection portion 310 of the connecting base 300 to achieve electrical connection between the fixing base 200 and the connecting base 300. Furthermore, the first electrical connection portion 210 and the second electrical connection portion 310 are both at the same axial height relative to the power supply housing. Therefore, after the fixing base 200 and the connecting base 300 are mated and connected, the lamp fixture device 400 can also have a relatively small thickness.

[0233] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
