Detailed Description

The following description is made with reference to the accompanying drawings the present invention will be described in further detail.

Referring to fig. 1 to 3, the lamp body electrical connection structure 100 includes a light source board 10, a socket 20, a driving board 30 and pins 40. The socket 20 is fixed on the light source board 10, the pin 40 is fixed on the driving board 30, and the pin 40 is inserted into the socket 20 to electrically connect the light source board 10 and the driving board 30 when electrically connected.

The light source board 10 is provided with a through hole 11, and a part of the structure of the socket 20 and a part of the structure of the pin 40 penetrate through the through hole 11.

The socket 20 is disposed on the bottom surface of the light source board 10 facing the driving board 30. The socket 20 includes a connecting portion 22 and a clamping portion 21. The socket 20 is fixed on the light source board 10 through the connection portion 22, the connection portion 22 includes a flat plate 221 and two bends 222 disposed at two ends of the flat plate 221, the two bends 222 are fixed on the light source board 10 and electrically connected with the light source board 10, and the two bends 222 are fixed on the electrodes of the light source board 10 through welding. The clamping portion 21 includes an opening 211 formed on the connecting portion and at least one elastic sheet 212 disposed on the periphery of the opening 211. The elastic piece 212 is disposed on a side of the connecting portion 22 away from the driving plate 30, and the elastic piece 212 is fixed on the connecting portion 22. The socket 20 is formed by integrally bending a metal sheet. After assembly, the spring plate 212 of the socket 20 extends into the through hole 11 of the light source board 10.

In the case of an electrical connection, the pin 40 is inserted into the opening 211 of the socket 20 to abut against the spring plate 212, so as to electrically connect the light source board 10 and the driving board 30. Preferably, the number of the elastic sheets 212 is two, and the two elastic sheets 212 are arranged in an inverted-V shape. Preferably, the clamping portion 21 further includes a guide ring 213, the guide ring 213 is fixed on the connecting portion 22, the elastic sheet 212 is fixed on the guide ring 213, the guide ring 213 and the elastic sheet 212 cooperate to form the opening 211, and the size of the opening 211 gradually decreases in a direction away from the driving plate 30.

Preferably, the lamp body electrical connection structure 100 includes two socket bases 20 and two pins 40 (as shown in fig. 1), where the socket bases 20 and the pins 40 are disposed in a one-to-one correspondence.

During assembly, the power panel 10 and the driving panel 30 are conveyed to a welding station to be respectively and automatically welded with the socket 20 and the pin 40, so that the power panel 10, the socket 20, the driving panel 30 and the pin 40 are welded together; then, the contact pin 40 is inserted into the opening 211 of the socket 20 by an automation device to be abutted against the elastic sheet 212 of the socket 20, so that the driving board and the light source board are electrically connected.

In summary, the lamp body electrical connection structure 100 is provided with the socket 20 and the pin 40, the socket 20 is fixed on the light source board 10, and the pin 40 is fixed on the driving board 30. During assembly, the contact pin 40 is inserted into the socket 20 to realize the electric connection between the light source board 10 and the driving board 30, so that the electric connection between the light source board 10 and the driving board 30 is realized without manually welding wires, and the lamp body electric connection structure has the advantages of high yield, high production efficiency, convenience and simplicity in assembly and suitability for automatic assembly. Since the opening 211 of the socket 20 extends from large to small in a direction away from the driving plate, this makes the obstruction encountered during the insertion of the pin 40 small, so that the lamp body electrical connection structure has the advantage of smooth assembly.

The socket 20 is disposed on the light source board 10 facing the bottom surface of the driving board 30 (as shown in fig. 1), and the elastic sheet 212 of the socket 20 is disposed on a side of the connecting portion away from the driving board 30, so that the elastic sheet 212 can elastically deform and simultaneously support the light source board 10 to the socket 20. If the socket 20 is disposed on the light source board 10 far from the top surface of the driving board 30, when the socket 20 is inserted by the pins 40, the force applied by the pins 40 is conducted to the two bends 222, so that the welding between the bends 222 and the light source board 10 may be disconnected and disabled. In addition, another effect caused by the elastic sheet 212 of the socket 20 being accommodated in the through hole 11 is that the height of the socket 20 on the light source board 10 is directly reduced, so that the socket 20 is prevented from shielding the light emitted by the LED light source while saving the material.
