[0024] Example 1

[0025] like Figure 1-5 As shown, a solderless light source assembly includes a bracket 1. The bottom surface of the bracket 1 is provided with a mounting groove 11. An integrated light source module 3 is provided in the mounting groove 11. The integrated light source module 3 includes a light control circuit board and an LED light source. The mounting groove 11 is provided with a light transmission hole 111, through which the integrated light source module 3 transmits light.

[0026] The mounting groove 11 has a fixing groove 12 on its side, and a power terminal 2 is provided at the fixing groove 12. The power terminal 2 includes a wiring groove 21, and a pressing spring 22 is provided inside the wiring groove 21. The pressing spring 22 is a barbed shape that extends inward from the side wall of the wiring groove 21 and is inclined. The end of the power cord can be directly inserted into the wiring groove 21, so that the power terminal 2 conducts power. The pressing spring 22 can clamp the power cord. Due to the structural characteristics of the pressing spring 22, it can effectively prevent the power cord from loosening. There are two pressing springs 22, which are arranged in parallel to each other, which makes the power cord connection more reliable. There is no need to solder between the power cord and the power terminal 2. The power cord can be connected at any time, and can be directly connected to the power supply network when the lamp is in use. The end face of the bracket 1 has a wiring hole 13 that communicates with the fixing groove 12. The power cord can be directly inserted into the wiring groove 21 through the wiring hole 13.

[0027] The wiring groove 21 is connected to an elastic sheet 23. The elastic sheet 23 extends from the edge of the fixing groove 12 into the mounting groove 11. The integrated light source module 3 is provided with a conductive contact 31 that contacts the elastic sheet 23 and conducts electricity. The elastic sheet 23 and the conductive contact 31 are in contact and conduct electricity.

[0028] The wiring groove 21, the top pressure spring 22, and the elastic sheet 23 are integrally stamped structures. The cross-section of the wiring groove 21 is U-shaped, and the top pressure spring 22 is formed by stamping from the side wall material of the wiring groove 21. The edge of the fixing groove 12 is provided with a limiting protrusion 121, which abuts against the wiring groove 21. The limiting protrusion 121 can prevent the wiring groove 21 from loosening from the fixing groove 12, making the installation more secure.

The fixing clips 4 are arranged on opposite sides of the mounting groove 11, which can fix the integrated light source module 3 on both sides, so that the integrated light source module 3 is stably fixed in the mounting groove 11.

[0030] Depending on the specifications of the integrated light source module 3 and the different power connection points required, such as Figure 5 As shown, there are two fixing slots 12, arranged diagonally. Each fixing slot 12 has a power terminal 2. This structure is suitable for integrated light source modules 3 that require two-point power connection. The integrated light source module 3 has two conductive contacts 31. (As shown...) Figure 6 As shown, there are four fixing slots 12 arranged at the four corners. Each of the four fixing slots 12 is equipped with a power terminal 2. This structure is suitable for integrated light source modules 3 that require four-point power connection. The integrated light source module 3 is equipped with four conductive contacts 31. The mounting groove 11 is equipped with supporting protrusions 14. The number and position of the supporting protrusions 14 correspond to the elastic sheet 23. The supporting protrusions 14 can support the integrated light source module 3, ensuring more reliable contact between the conductive contacts 31 and the elastic sheet 23.

[0031] The working process of this embodiment is as follows: During assembly, the wiring groove 21 is pressed into the fixing groove 12 to fix the power terminal 2. Then, the conductive contact 31 is aligned with the elastic sheet 23, and the integrated light source module 3 is installed in the mounting groove 11. At this time, the fixing buckle 4 is engaged and the position of the integrated light source module 3 is restricted to prevent it from loosening.

[0032] Example 2

The pressure spring 22 is a barbed shape extending inward from the side wall of the wiring groove 21 and inclined. The end of the power cord can be directly inserted into the wiring groove 21, allowing the power connection terminal 2 to conduct power. The pressure spring 22 clamps the power cord, effectively preventing it from loosening due to its structural characteristics. Two pressure springs 22 are provided and arranged parallel to each other, making the power cord connection more reliable. No soldering is required between the power cord and the power connection terminal 2, allowing for power cord connection at any time, including direct connection to the power grid when the light fixture is in use.

[0034] The wiring groove 21 is connected to an elastic sheet 23, which is used to make contact with the conductive contact 31 on the integrated light source module 3 to conduct electricity. The wiring groove 21, the top pressure spring 22 and the elastic sheet 23 are stamped as a single integrated structure. The cross-section of the wiring groove 21 is U-shaped and the top pressure spring 22 is formed by stamping the side wall material of the wiring groove 21.

[0035] The working process of this utility model is as follows: During assembly, the wiring groove 21 is pressed into the fixing groove 12 to fix the power terminal 2. Then, the conductive contact 31 is aligned with the elastic sheet 23, and the integrated light source module 3 is installed in the mounting groove 11.
