[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] See also Figures 1 to 6 As shown, the utility model discloses a lamp 100, comprising a lamp body 1 and a bracket assembly 2, wherein the bracket assembly 2 is used to install the lamp body 1 on a mounting surface.

[0041] The lamp body 1 includes a chassis 11 and an electrical connector 12 . A groove 10 is provided on a side of the chassis 11 facing the mounting surface. The electrical connector 12 is assembled and fixed in the groove 10 .

[0042] Preferably, the electrical connector 12 is provided with a clamping portion 124, and the chassis 11 is correspondingly provided with a clamping slot 114, and the clamping portion 124 cooperates with the clamping slot 114 to achieve clamping and fixing of the electrical connector 12 and the chassis 11. Of course, in other embodiments, the clamping and fixing method may not be adopted, and this is not limited. In this embodiment, in order to ensure firm fixation, while the electrical connector 12 and the chassis 11 are clamped, screws are further used to further strengthen the fixation.

[0043] The hanger assembly 2 includes a hanger 21 and a docking connector 22 fixedly connected to the hanger 21 . One end of the docking connector 22 is connected to the mains, and the other end is adapted to the electrical connector 12 .

[0044] When the chassis 11 and the bracket 21 are fixedly connected, the electrical connector 12 and the docking connector 22 are plugged into each other to be electrically connected, and the other side of the electrical connector 12 is connected to the controller inside the lamp 100. In this way, the current conduction of the lamp 100 can be achieved by only connecting the mains to the docking connector 22.

[0045] The docking connector 22 is provided with a clamping portion 221, and the bracket 21 is correspondingly provided with a clamping groove 211, and the clamping portion 221 extends into the clamping groove 211 to achieve clamping and fixing of the docking connector 22 and the clamping groove 211. Of course, in other embodiments, screws can also be used for fixing, which is not limited to this, and it is only necessary to ensure that the docking connector 22 and the bracket 21 are fixed.

[0046] The docking connector 22 is also preset with a guide post 222 , and the bracket 21 is correspondingly provided with a guide groove 212 , and the guide post 222 cooperates with the guide groove 212 to fix the docking connector 22 at a preset position.

[0047] In this embodiment, the hanger 21 is a metal frame, and a metal piece 23 is further provided between the hanger 21 and the docking connector 22, and the metal piece 23 is used to fix the hanger 21 and the docking connector 22, and the metal piece 23 is also configured to electrically connect the hanger 21 and the docking connector 22 to ground the hanger 21. In this way, by providing the metal piece 23, the mechanical and electrical connection between the hanger 21 and the docking connector 22 is simultaneously achieved.

[0048] Preferably, the hanger 21 is provided with a fixing hole 214, and the metal member 23 is fixed inside the docking connector 22 after passing through the fixing hole 214. The hole diameter of the fixing hole 214 is smaller than that of the metal member 23, so that the metal member 23 is fixed more firmly.

[0049] The surface of the hanger 21 is sprayed with an anti-corrosion coating to prevent the hanger 21 from rusting. When the metal part 23 penetrates the fixing hole 214, it can pierce the coating attached to the inner or outer surface of the fixing hole 214, thereby ensuring the conduction of current in the metal part 23.

[0050] In this embodiment, the lamp body 1 is configured to be horizontally movable relative to the bracket assembly 2, so that the chassis 11 and the bracket 21 are fixedly connected, and the electrical connector 12 and the docking connector 22 are electrically connected. In other words, the mechanical and electrical connection between the lamp body 1 and the bracket assembly 2 can be achieved while pushing the lamp body 1 to move.

[0051] For details, please combine Figure 7 As shown, a positioning member 113 is riveted on the chassis 11, and a positioning groove 213 is correspondingly provided on the bracket 21. The positioning groove 213 is provided with a first area 2131, a second area 2132 and a slide groove 2133 connecting the first area 2131 and the second area 2132. When the lamp body 1 moves horizontally relative to the bracket assembly 2, the positioning member 113 enters the second area 2132 from the first area 2131 along the slide groove 2133 to achieve a fixed connection between the chassis 11 and the bracket 21.

[0052] That is to say, in this embodiment, the chassis 11 and the bracket 21 are pre-installed by the positioning member 113. Furthermore, it can be said that the lamp body 1 and the bracket assembly 2 are first fixed on the installation surface in the vertical direction, and then the lamp body 1 is pushed to achieve a horizontal fixation. When the first step of vertical fixation is achieved, the installer can properly release his hands, so there is no need to hold the lamp body 1 or the bracket assembly 2 throughout the installation process, which is more labor-saving.

[0053] The electric connector 12 of the utility model can be smoothly inserted into the docking connector 22 under the drive of the chassis 11. In this embodiment, the electric connector 12 is a plug, and the docking connector 22 is a socket. Of course, in other embodiments, the electric connector 12 can also be set as a socket, and the docking connector 22 can be set as a plug, which is not limited to this.

[0054] For details, please combine Figures 8 to 11 As shown, the electrical connector 12 includes a base 121 and a docking portion 122, and the docking portion 122 can move in at least two directions relative to the base 121. The electrical connector 12 and the docking connector 22 are in the same horizontal plane. When the electrical connector 12 and the docking connector 22 are plugged in, because there is a gap between the electrical connector 12 and the docking connector 22, and the direction of the force applied by the installer may deviate, when the electrical connector 12 is inserted into the docking connector 22, the docking portion 122 will be displaced under the reaction thrust of the docking connector 22, so as to achieve smooth plugging with the docking connector 22.

[0055] Specifically, the electrical connector 12 further includes a positioning seat 123, the base 121 is provided with a mounting groove 1210 and a mounting hole 1211 that are interconnected, and the docking portion 122 is assembled in the mounting groove 1210 so as to be electrically connected to the docking connector 22. The positioning seat 123 is received in the mounting hole 1211, and a first receiving hole 1231 and a second receiving hole 1232 that are perpendicular to each other are concavely provided in the positioning seat 123, and the opening of the first receiving hole 1231 faces the mounting groove 1210. In other words, the first receiving hole 1231 and the mounting groove 1210 are interconnected.

[0056] The electrical connector 12 further includes a first elastic member 125 and a second elastic member 126. The first elastic member 125 is received in the first receiving hole 1231, and one end of the first elastic member 125 abuts against the positioning seat 123 and the other end abuts against the docking portion 122. The second elastic member 126 is received in the second receiving hole 1232, and one end of the second elastic member 126 abuts against the positioning seat 123 and the other end abuts against the base 121. The first elastic member 125 and the second elastic member 126 are perpendicular to each other, so that the docking portion 122 can move in at least two different directions relative to the base 121. In other words, the displacement direction of the docking portion 122 is the compression direction of the first elastic member 125 and / or the second elastic member 126.

[0057] The base 121 includes an upper shell 1212 and a lower shell 1213 assembled with each other. The middle position of the upper shell 1212 is recessed downward and forms the assembly groove 1210 together with the upper surface of the lower shell 1213. The assembly hole 1211 is first recessed from the assembly groove 1210 toward the interior of the upper shell 1212 and then recessed toward the interior of the lower shell 1213.

[0058] There is a gap between the docking portion 122 and the lower shell 1213, and when the second elastic member 126 is compressed, the docking portion 122 moves toward the lower shell 1213 to abut against the lower shell 1213. In other words, when the second elastic member 126 is in a normal state, the docking portion 122 does not contact the upper surface of the lower shell 1213, which reserves a space for the displacement of the docking portion 122 in the vertical direction.

[0059] The docking portion 122 includes an electrical connection portion 1221 and a positioning portion 1222 . The positioning portion 1222 is formed to extend outward from an outer wall surface of the electrical connection portion 1221 , and an extending direction of the positioning portion 1222 is perpendicular to a plug-in direction of the electrical connector 12 and the docking connector 22 .

[0060] In this embodiment, two positioning parts 1222 are provided and symmetrically arranged at both ends of the electrical connection part 1221, two positioning seats 123 are provided, and two assembly holes 1211 are also provided accordingly. The two positioning parts 1222 are respectively inserted into the first receiving holes 1231 of the corresponding positioning seats 123 and connected to the positioning seats 123. Such an arrangement makes the fixation of the docking part 122 and the base 121 more stable, and also provides a path for the docking part 122 to move to both sides. Of course, in other embodiments, only one positioning seat 123, positioning part 1222 and assembly hole 1211 may be provided, and there is no limitation to this.

[0061] In this embodiment, the positioning portion 1222 partially extends into the first receiving hole 1231 , a first docking hole 12221 is recessed in the positioning portion 1222 , one end of the first elastic member 125 is received in the first receiving hole 1231 , and the other end is received in the first docking hole 12221 .

[0062] A second docking hole 1215 is recessed in the base 121, and the recessed direction of the second docking hole 1215 is opposite to the recessed direction of the second receiving hole 1232, and both are parallel to the recessed direction of the assembly groove 1210. One end of the second elastic member 126 is accommodated in the second receiving hole 1232, and the other end is accommodated in the second docking hole 1215.

[0063] The lower shell 1213 is provided with a through groove 1214 which is connected to the assembly groove 1210, and the through groove 1214 passes through the lower shell 1213 from top to bottom. The electrical connection part 1221 includes a first electrical connection part 12211 and a second electrical connection part 12212. The first electrical connection part 12211 is accommodated in the assembly groove 1210 to be plugged with the docking connector 22, and the second electrical connection part 12212 is accommodated in the through groove 1214 and is connected to the controller inside the lamp 100.

[0064] In this embodiment, the first electrical connection portion 12211 further includes a bearing plate 12213 that can be moved to abut against the lower shell 1213, and a guide rib 12214 is provided on the side of the bearing plate 12213 away from the lower shell 1213. When the chassis 11 and the hanger 21 are in a pre-installed state, the docking connector 22 is partially located on the bearing plate 12213. When the chassis 11 is pushed, the guide rib 12214 supports the docking connector 22 and slides toward the docking connector 22 until the electrical connector 12 and the docking connector 22 are plugged in. In other words, by providing the guide rib 12214, the electrical connector 12 is given a plug-in guide, which is more conducive to the plug-in of the electrical connector 12 and the docking connector 22.

[0065] In summary, the electrical connector 12 and the lamp 100 of the utility model are provided with an assembly groove 1210 and an assembly hole 1211 in the base 121 of the electrical connector 12, and a positioning seat 123 is assembled in the assembly hole 1211, so that the first elastic member 125 is accommodated in the first receiving hole 1231 of the positioning seat 123, and the second elastic member 126 is accommodated in the second receiving hole 1232 of the positioning seat 123, and one end of the first elastic member 125 abuts against the positioning seat 123, and the other end abuts against the docking portion 122 of the electrical connector 12, and one end of the second elastic member 126 abuts against the positioning seat 123, and the other end abuts against the base 121, so that the docking portion 122 of the electrical connector 12 can move in at least two different directions relative to the base 121, so that the plug-in with the docking connector 22 is more flexible and the alignment is more precise.

[0066] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
