The cover 2 is provided with a light-transmitting hole for the LED light source 3 to emit light. The LED light source 3 and the metal connecting piece 4 are respectively mounted between the base 1 and the cover 2. The metal connecting piece 4 is used to connect external wires. The LED light source 3 has an electrical contact area (not shown in the figure) on the side facing the circuit board 5, which forms an electrical connection with the circuit board 5. The circuit board 5 has an electrical contact area (not shown in the figure) that forms an electrical connection with the metal connecting piece 4. After the cover 2 and the base 1 are assembled, the LED light source 3, the circuit board 5, and the metal connecting piece 4 are connected to the external wires (not shown in the figure).

[0043] In this embodiment, the base 1 and the cover 2 are generally circular in shape, and in other embodiments they can also be square or other shapes. Both form a mounting space that is compatible with the LED light source 3 and the metal connecting piece 4, so that the LED light source 3 and the metal connecting piece 4 can be completely accommodated in the space.

[0044] Specifically, the LED light source 3 is arranged on the base 1 and connected with the circuit board 5; the cover 2 is provided with an elastic limiting piece 6, and the circuit board 5 is pressed under the cover fastening of the cover 2 to limit the displacement of the circuit board 5. In this embodiment, the LED light source 3 is directly arranged on the base 1, and the circuit board is attached on the LED light source. The circuit board 5 and the LED light source 3 always maintain close contact under the continuous pressing force provided by the elastic limiting piece 6, which ensures stable electrical connection and avoids the problem of poor contact caused by looseness or displacement.

[0045] In this embodiment, the light transmission hole is located in the middle of the base 1, and a mounting groove 11 for accommodating the LED light source 3 is arranged on the outer periphery of the light transmission hole, so that the LED light source 3 is erected on the outer periphery of the light transmission hole and does not deviate from the base 1.

[0046] In this embodiment, the circuit board 5 is a PCB circuit board.

[0047] Optionally, the elastic limiting piece 6 includes a contact body 61 abutting against the circuit board and an elastic deformation part 62 integrally formed with the contact body, and the elastic deformation part 62 is deformed under the cover fastening of the cover 2 to press the contact body 61 on the circuit board 5.

[0049] In order to improve the deformation force of the elastic limiting piece 6, further, the contact body 61 is V-shaped or U-shaped protruded towards the circuit board and abuts against the circuit board with interference.

[0050] In this embodiment, the contact body 61 is designed to be V-shaped or U-shaped protruded towards the circuit board and bent with the elastic deformation part, which can significantly increase the deformation capacity of the elastic limiting piece 6 and provide a larger elastic deformation space, so that the limiting piece can generate a larger pressing force to press the circuit board 5 more firmly and ensure stable contact with the LED light source 3.

[0051] Further, the cover 2 is provided with a limiting groove 21 for mounting the elastic limiting piece 6, the elastic limiting piece is located in the limiting groove 21, the elastic deformation part abuts against the bottom of the limiting groove 21, and the limiting feet 63 on both sides thereof abut against the side walls of the limiting groove with interference. In addition, the limiting feet 63 of the elastic limiting piece are provided with a bent deformation part 631 to improve the deformation force thereof.

[0053] In the embodiment, the cross-sectional structure of the elastic limiter 6 is approximately M-shaped, which provides a larger contact surface, so that the elastic limiter 6 is more uniformly and stably in contact with the circuit board 5 or the base 1. By increasing the contact area, the pressure applied to the limiter can be effectively dispersed, and the local stress concentration can be reduced, thereby reducing the risk of deformation or damage of the assembly due to excessive local stress, and ensuring the continuous and stable connection between the circuit board 5 and the LED light source 3.

[0054] Optionally, the base 1 is provided with a mounting groove 11 matched with the metal connector 4, and the metal connector 4 is fixed in the mounting groove 11; one end of the metal connector 4 extends to provide a connecting piece 41, the connecting piece 41 is in contact with the circuit board 5; the other end of the metal connector 4 is provided with a wire clamping frame 42 for accommodating a wire, and the wire clamping frame 42 is provided with a wire clamping piece 43 for electrically connecting with the wire.

[0057] In addition, the limiting structure, such as the limiting foot and the limiting groove, the limiting column and the limiting hole, arranged between the circuit board and the base or the cover, forms a multiple fixing effect, effectively preventing loosening; the close fit between the limiting foot and the limiting groove limits the movement of the elastic limiter, so that it can withstand external pressure or impact without displacement; further, the wire clamping frame and the wire clamping piece of the metal connector tightly clamp the external wire, which not only ensures the stability of electrical connection, but also prevents the problem of poor contact caused by vibration or pulling the wire.

[0058] Example 2

[0059] like Figures 6-10 As shown, this embodiment 2 provides an LED light source connector. The difference between this embodiment 2 and embodiment 1 is that the structure of the elastic limiting member 6 is different:

[0061] Example 3

[0062] like Figures 11-15 As shown, this embodiment 3 provides an LED light source connector. The difference between this embodiment 3 and embodiment 2 is that the structure and distribution of the elastic limiting member 6 are different, and the distribution of the metal connector 4 is also different:

[0063] The two elastically deformable portions of the two elastic limiting members 6 are integrally formed and located on one side of the circuit board 5, extending along the side of the circuit board 5.

[0064] The two metal connectors 4 are located on the opposite side of the elastic limiting member 6 and are spaced apart.

[0065] This design primarily utilizes the symmetrical distribution of elastic limiting components and metal connectors to achieve a more balanced force on the circuit board, resulting in a more stable connection and avoiding problems such as poor contact caused by uneven force distribution.
