The conductive connecting piece 4 of the embodiment can be a metal terminal, and the insulating fixing piece 6 can be made of plastic material; of course, other materials having the same or similar properties as those of the prior art may be used. One end of the conductive connecting piece 4 is in conductive connection with the conductor 3 of the light-emitting component 2, and the other end of the conductive connecting piece 4 is in conductive connection with power supply equipment; the insulating fixing piece 6 is matched with the conductive connecting piece 4, and after the insulating fixing piece 6 is deformed by external force, the insulating fixing piece 6 limits and fixes the conductive connecting piece 4 on the insulating part.
Specifically, the conductive connecting piece 4 includes a body 5 and an extension piece 18, the extension piece 18 is disposed on one side of the body 5, and the body 5 cooperates with the insulating fixing piece 6 to fix the conductive connecting piece 4; the extension 18 is in contact with the conductor 3 of the light emitting assembly 2 for an electrically conductive connection. In this embodiment, the end of the extension member 18 is inclined to the side close to the conductor 3 of the light emitting component 2, so that after the conductive connection member 4 is fixed to the insulation part, the extension member 18 naturally abuts against the conductor 3 of the light emitting component 2, thereby realizing conductive connection between the conductive connection member 4 and the conductor 3 of the light emitting component 2. Further, in order to better achieve an electrically conductive connection of the extension member 18 to the light emitting assembly 2, a protruding structure 16 is provided at the end of the extension member 18 at the side close to the conductor 3.
In the conventional assembly process, the electric wire 7 needs to be welded on the light emitting component 2 in advance, and then the light emitting component 2 and the components such as the COB bracket are installed, so that the assembly process is complicated, and the assembly of the light emitting component 2 is inconvenient. In this embodiment, the extension piece 18 is in contact with the conductor 3 of the light emitting component 2 to realize conductive connection, so that connection of the light emitting component 2 and conductors such as the wire 7 is effectively simplified, and the conductive connection of the light emitting component 2 is completed while the conductive connection piece 4 is assembled, so that the operation is convenient, the procedure of welding the wire 7 on a wafer in the early stage is omitted, the production process is simplified, and the method is more suitable for automatic production and assembly, and the production efficiency is improved.
For better mating fixation between the conductive connection 4 and the insulating fixture 6, at least one mounting hole 17 may be provided on the body 5, and at least one insulating fixture 6 may be provided in each of the mounting holes 17.

In this way, by the cooperation of the two insulating fixtures 6 with the mounting holes 17, the restriction and positioning of the planar movement of the conductive connecting member 4 are achieved. When the conductive connecting member 4 is fixed, the insulating fixing member 6 is pressed to deform, and after the diameter is increased and the height is reduced (the area is enlarged and the thickness is reduced), the compaction and fixation of the body 5 are completed, thereby realizing the fixation of the conductive connecting member 4.

Like this, insulating mounting 6 pressfitting is in the edge of body 5 for the middle part position of body 5 can set up to seal structure, thereby can set up assembly structure more nimble on body 5, so as to cooperate with other metal conductor 3 or electric wire 7, and then realize with power supply unit's conductive connection. For example, a female fitting structure may be provided on the body 5 for a male fitting with the electric wire 7, and the detailed description will be made with reference to the prior art.

The positioning groove 12 is arranged so as to accurately and firmly place the conductive connecting piece 4 on the frame body 1 during assembly, thereby being beneficial to improving the position accuracy of the conductive connecting piece 4; meanwhile, in the subsequent press-fitting process, the insulating fixing piece 6 can be deformed to better compact and fix the conductive connecting piece 4 on the frame body 1, so that the conductive connecting piece 4 is fixed. Further, the insulating fixing member 6 of the present embodiment is also provided in the positioning groove 12 corresponding to the mounting hole 17 of the body 5 of the conductive connecting member 4.
