[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0053] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This embodiment provides a light source module, which includes an adapter plate 10 and a plurality of light strips 20. Each light strip 20 includes a light panel 21 and a plurality of LED lights 22 located on the light panel 21. A first connector 23 is provided at one end of each light panel 21. A plurality of second connectors 11 are provided at intervals on at least one of the opposite sides of the adapter plate 10. The adapter plate 10 is connected to the first connector 23 of the corresponding light strip 20 through the plurality of second connectors 11 to form an electrical connection between the light panel 21 and the adapter plate 10.

[0054] In this configuration, multiple second connectors 11 can be spaced out on one of the opposite sides of the adapter plate 10, or multiple connectors can be spaced out on both opposite sides of the adapter plate 10. If multiple second connectors 11 are spaced out on either side of the adapter plate 10, when the light strip 20 is inserted into the second connector 11 of the adapter plate 10 through the first connector 23, the multiple light strips 20 can be distributed on the same side of the adapter plate 10. Thus, when arranging the backlight module, the adapter plate 10 is positioned relative to the side of the entire backlight module. If the adapter plate 10 has second connectors 11 spaced out on both opposite sides, when the light strip 20 is inserted into the second connector 11 of the adapter plate 10 through the first connector 23, the multiple light strips 20 can be distributed on both opposite sides of the adapter plate 10. Thus, when arranging the backlight module, the adapter plate 10 is positioned relatively in the middle, while the multiple light strips 20 are located on both opposite sides of the adapter plate 10, arranged longitudinally relative to the adapter plate 10, and arranged laterally on both sides of the adapter plate 10.

[0055] It should be noted that the embodiments of this application take the example of having a second connector 11 on both opposite sides of the adapter board 10 to illustrate the structure of the adapter board 10.

[0056] In this embodiment, by setting a first connector 23 in the light strip 20 and a corresponding second connector 11 in the adapter plate 10, the electrical connection between the light board 21 and the adapter plate 10 can be directly achieved through the plugging between the first connector 23 and the second connector 11 during assembly. There is no need to set an additional screw structure for assembly, which simplifies the assembly process and can effectively improve the assembly efficiency.

[0057] Please refer to the following: Figure 4 , Figure 5 and Figure 6 In some embodiments, the socket formed by the first connector 23 is located on one side of the lamp board 21, and the LED lamp 22 is located on the other side of the lamp board 21; the first connection terminal 111 of the second connector 11 is located on the side facing the lamp board 21; the first connection terminal 111 in the second connector 11 is used for electrical connection with the connection pin in the first connector 23.

[0058] In this embodiment, the first connector 23 formed in the lamp plate 21 has a socket; while the adapter plate 10 forms a second connector 11 by providing a protrusion, which is provided with a connection point for electrical connection, namely a first connection terminal 111. During assembly, the protrusion in the adapter plate 10 is inserted into the socket in the first connector 23 for connection; when the lamp strip 20 is inserted into the adapter plate 10, the lamp plate 21 is located above the adapter plate 10, and the adapter plate 10 is located below the lamp plate 21. The first connection terminal 111 provided on the protrusion in the adapter plate 10 can face one side of the lamp plate 21, which is equivalent to the first connection terminal 111 of the protrusion being located on the front, thereby realizing electrical connection with the connection pin in the first connector 23.

[0059] In one embodiment, the adapter board 10 is a PCB board, and the first connecting terminal 111 can be formed by exposing copper on the PCB board. Alternatively, a metal layer can be plated onto the exposed copper area to form the first connecting terminal 111. For example, gold plating can be used to form gold fingers as the second connector 11, or silver plating can be used. Compared to other types of connectors, this design is simple in structure and low in cost.

[0060] It should be noted that in the embodiments of this application, a protrusion can also be provided on the side of the lamp board 21 to form a first connector, and a connection point for electrical connection can be provided in the first connector; at this time, the second connector on the side of the corresponding adapter plate 10 has a socket to realize the insertion between the lamp board 21 and the adapter plate 10.

[0061] Please continue reading Figure 5Specifically, in this embodiment, the first connector 23 includes a plurality of first connecting pins 231, a first fixing base 232, and a first insulating member 233. The first fixing base 232 has a first connecting cavity and a plurality of first mounting slots. The plurality of first mounting slots are used to fix each of the first connecting pins 231, such that one end of the first connecting pin 231 is exposed in the first connecting cavity, and the other end of the first connecting pin 231 extends out of the first connecting cavity. The first connecting cavity is used to form the socket of the first connector 23. One end of the first connecting pin 231 is used to connect with the first connecting terminal 111 in the second connector 11, and the other end of the first connecting pin 231 is used to connect with the second connecting terminal 211 in the lamp board 21, and the second connecting terminal 211 is located on the second side of the lamp board 21. The first insulating member 233 is fixedly connected to the first fixing base 232 and is used for insulation between the first connecting pins 231 and the lamp board 21.

[0062] In this embodiment, the insertion direction of the socket formed by the first connecting cavity is the same as the extension direction of the lamp board 21 relative to the first connector 23; wherein, one end of the first connecting pin 231 is exposed at the top of the first connecting cavity and towards the bottom of the first connecting cavity. When plugged in, the first connecting terminal 111 of the protrusion is inserted towards the top of the first connecting cavity (i.e., the side facing the lamp board 21) and electrically connected to one end of the first connecting pin 231 to facilitate the formation of an electrical connection; at this time, the first connecting terminal 111 in the adapter plate 10 is located on the front side of the protrusion.

[0063] In this embodiment, the other end of the first connection pin 231 is exposed and connected to the second connection terminal 211 on the second side of the lamp board 21. One end of the first connection pin 231 is located in the first connection cavity forming one side of the lamp board 21, which is equivalent to the other end of the first connection pin 231 being exposed and crossing from one side of the lamp board 21 to the other side. Therefore, in order to avoid the first connection pin 231 from contacting the lamp board 21 when crossing the lamp board 21, a first insulating member 233 is provided between the lamp board 21 and the first connection pin 231 for insulation, thereby improving the reliability of the connection.

[0064] Please refer to the following: Figure 7 , Figure 8 , Figure 9 and Figure 10 In some embodiments, the socket formed by the first connector 23 is located on one side of the lamp board 21, and the LED lamp 22 is located on the other side of the lamp board 21; the first connection terminal 111 in the second connector 11 is located on the side opposite to the lamp board 21; the first connection terminal 111 in the second connector 11 is used for electrical connection with the connection pin in the first connector 23.

[0065] Similarly, in this embodiment, when the light strip 20 is plugged into the adapter plate 10, the light plate 21 is located above the adapter plate 10, and the adapter plate 10 is located below the light plate 21. In this embodiment, the first connecting terminal 111 provided on the protrusion of the adapter plate 10 can be located on the side away from the light plate 21, which is equivalent to the first connecting terminal 111 of the protrusion being located on the back side, thereby realizing electrical connection with the connecting pin in the first connector 23.

[0066] Specifically, in this embodiment, the first connector 23 includes a plurality of second connecting pins 234, a second fixing base 235, and a second insulating member 236. The second fixing base 235 has a second connecting cavity and a plurality of second mounting slots. The plurality of second mounting slots are used to fix each of the second connecting pins 234, such that one end of the second connecting pin 234 is exposed in the second connecting cavity, and the other end of the second connecting pin 234 extends out of the second connecting cavity. The second connecting cavity is used to form the socket of the first connector 23. One end of the second connecting pin 234 is used to connect with the first connecting terminal 111 in the second connector 11, and the other end of the second connecting pin 234 is used to connect with the second connecting terminal 211 in the lamp board 21, and the second connecting terminal 211 is located on the second side of the lamp board 21. The second insulating member 236 is fixedly connected to the second fixing base 235 and is used for insulation between the second connecting pins 234 and the lamp board 21.

[0067] In this embodiment, the insertion direction of the socket formed by the second connecting cavity is the same as the extension direction of the lamp board 21 relative to the first connector 23; wherein, one end of the first connecting pin 231 is located at the bottom of the second connecting cavity and protrudes towards the top of the second connecting cavity. When plugged in, the first connecting terminal 111 of the protrusion is inserted towards the bottom of the second connecting cavity (i.e., the side away from the lamp board 21) and abuts against one end of the first connecting pin 231 to facilitate the formation of an electrical connection; at this time, it is equivalent to the first connecting terminal 111 in the adapter plate 10 being located on the back side of the protrusion.

[0068] Please continue reading. Figure 8 As one embodiment, the other end of the second connection pin 234 is provided with a first sub-pin 2341 and a second sub-pin 2342; the first sub-pin 2341 and the second sub-pin 2342 are used to electrically connect with the same first connection terminal 111 in the second connector 11; that is, in this embodiment, by providing two sub-pins for the second connection pin 234, when the first connector 23 is plugged into the second connector 11, each second connection pin 234 can be electrically connected to a corresponding first connection terminal 111 through the two sub-pins, ensuring the reliability of the connection between the first connector 23 and the second connector 11.

[0069] Please refer to the following: Figure 11, Figure 12 and Figure 13 In some embodiments, the socket formed by the first connector 23 is located on the same side of the lamp board 21 as the LED lamp 22; the first connection terminal 111 in the second connector 11 is located on the side facing the lamp board 21; the first connection terminal 111 in the second connector 11 is used for electrical connection with the connection pin in the first connector 23.

[0070] In this embodiment, the first connector 23 formed in the lamp plate 21 has a socket; while the adapter plate 10 forms a second connector 11 by providing a protrusion, which is provided with a connection point for electrical connection, namely a first connection terminal 111. During assembly, the protrusion in the adapter plate 10 is inserted into the socket in the first connector 23 for connection. In this embodiment, the lamp plate 21 is located below the adapter plate 10, and the adapter plate 10 is located above the lamp plate 21. The first connection terminal 111 on the corresponding protrusion can be provided on the side facing the lamp plate 21, abutting against the second connection terminal 211 in the first connector 23. This is equivalent to the first connection terminal 111 of the protrusion being located on the back side, thereby realizing the electrical connection between the lamp plate 21 and the adapter plate 10.

[0071] Specifically, as one embodiment, the first connector 23 in this embodiment includes a plurality of third connection pins 237 and a third fixing seat 238. The third fixing seat 238 has a third connection cavity and a plurality of third mounting slots. The plurality of third mounting slots are used to fix each third connection pin 237, such that one end of the third connection pin 237 is exposed in the third connection cavity, and the other end of the third connection pin 237 extends out of the third connection cavity. The third connection cavity is used to form the socket of the first connector 23.

The second connection terminal 211 and the LED lamp 22 are located on the same side of the lamp board 21.

[0072] In this embodiment, the socket formed by the third connecting cavity, the second connecting terminal 211, and the LED light 22 are all located on the same side of the lamp plate 21, so corresponding insulating parts are not required. During insertion, the adapter plate 10 is located above the lamp strip 20, one end of the third connecting pin 237 is located at the bottom of the third connecting cavity and protrudes towards the top of the third connecting cavity, and the first connecting terminal 111 in the adapter plate 10 is located on the back of the protrusion and abuts against the third connecting pin 237 to form an electrical connection.
