[0053] The embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the embodiments of this application are primarily intended to illustrate possible implementations of the technical solutions of this application and should not be construed as limiting the technical solutions of this application. In this specification, identical or similar components are indicated by identical or similar reference numerals.

[0054] Figure 1a A front view of the circuit assembly 100 provided in an embodiment of this application. Figure 1b for Figure 1a Right view of the circuit assembly 100 shown. Figure 1c for Figure 1a Bottom view of the circuit assembly 100 shown.

[0055] like Figure 1a As shown in Figure 1c, an embodiment of this application provides a circuit assembly 100, which includes a circuit board 10 and a plurality of electronic components 20 disposed on the circuit board 10. The circuit board 10 can be a printed circuit board, which has a plurality of shared pads 11, a plurality of independent pads 12 and a plurality of vias 13. The plurality of shared pads 11 and the plurality of independent pads 12 are used to connect to a first type of connector, and the plurality of shared pads 11 and the plurality of vias are used to connect to a second type of connector.

[0056] In this embodiment, the first type connector and the second type connector are different types of connectors. The circuit board 10 in the circuit assembly 100 can be used to adapt and connect at least two different types of connectors, which significantly expands the application scenarios of the circuit assembly 100 and makes it compatible with different customer needs.

[0057] The plurality of electronic components 20 may include a light source 21, which may be a monochrome LED, a dual-color LED, or an RGB LED. The light source 21 is mounted on the circuit board 10 and is used to emit light according to an external control signal. In this case, the circuit assembly 100 can be used as a light source module for a motor vehicle to emit light outwards. For example, the circuit assembly 100 can be used as a light source module for interior lighting in a motor vehicle, and it can work with light guides, lenses, and / or other optical elements to achieve the lighting effect of the interior lighting target. In addition to the light source 21, the electronic components 20 may also include resistors, capacitors, chips, etc., which will not be detailed here.

[0058] Specifically, the number of shared pads 11 can be four, namely a first shared pad 111, a second shared pad 112, a third shared pad 113, and a fourth shared pad 114. The first shared pad 111, the second shared pad 112, the third shared pad 113, and the fourth shared pad 114 are spaced apart from each other along the first direction Y of the circuit board 10. The shared pads 11 are generally rectangular with missing corners; the shapes of the four shared pads 11 can be identical or not entirely the same.

[0059] The number of independent pads 12 can be two, namely a first independent pad 121 and a second independent pad 122. The first independent pad 121 and the second independent pad 122 are spaced apart from each other along the first direction Y of the circuit board 10. The first independent pad 121 and the second independent pad 122 are located on opposite sides of the four shared pads 11 along the first direction Y of the circuit board 10, i.e. Figure 1a The top and bottom sides from the viewing angle; and these two independent pads 12 are located on one side of the four shared pads 11 along the second direction X of the circuit board 10, that is Figure 1a The right side from the perspective; the second direction X is perpendicular to the first direction Y. The shape of the independent pad 12 is roughly a rectangle missing some corners, and the shape and size of these two independent pads 12 can be set to be the same.

[0060] The plurality of vias 13 can be two, namely a first via 131 and a second via 132. The first via 131 and the second via 132 are spaced apart from each other along the first direction Y of the circuit board 10. The two vias 13 are located between the first independent pad 121 and the second independent pad 122. The vias 13 are generally cylindrical in shape, and the shape and size of the two vias 13 can be set to be the same.

[0061] It is worth noting that in other embodiments, the number, position, and shape of the shared pad 11, the independent pad 12, and the via 13 can be different. This application does not impose specific limitations on this.

[0062] In some embodiments, the circuit assembly 100 may further include a connector disposed on the circuit board 10 for receiving external control signals. These external control signals can be used to control the operation of the light source 21. Specifically, the connector may be selected from a first type connector, a second type connector, and a third type connector; correspondingly, the connector may be connected to a portion of the structure of the shared pad 11, the independent pad 12, and the via 13, with the specific connection location depending on the type of connector. The specific connection locations of these three different types of connectors—the first type connector, the second type connector, and the third type connector—on the circuit board 10 are described in detail below.

[0063] Figure 2 It shows Figure 1a The connection area in the circuit assembly 100 shown is used for connection with the first type connector 70. Figure 3a A front view of a first type connector 70 provided for an embodiment of this application. Figure 3b for Figure 3a The right view of the first type connector 70 shown. Figure 3c for Figure 3a The bottom view of the first type connector 70 shown.

[0064] like Figure 2 and Figures 3a-3c As shown, when the connector provided on the circuit board 10 is a first type connector 70, the connector is connected to the first area 11a of the shared pad 11 and the independent pad 12. Figure 2 The area marked in black is the area where the first type of connector 70 is soldered.

[0065] The first type connector 70 includes a first connecting terminal 71, a first supporting terminal 72, and a first insulating portion 73. The first insulating portion 73 is an insulating shell, and the first connecting terminal 71 and the first supporting terminal 72 are disposed within the cavity of the insulating shell 73. The first connecting terminal 71 is used to receive external power signals and control signals, and the first supporting terminal 72 is used to stably fix the first type connector 70 to the circuit board 10. The first type connector 70 can be an SMD connector with an insulating shell.

[0066] Specifically, the first ends 71a of the four first connection terminals 71 are soldered one-to-one to the first regions 11a of the four shared pads 11. The first regions of the first shared pad 111, the second shared pad 112, the third shared pad 113, and the fourth shared pad 114 are in... Figure 2 These are labeled 111a, 112a, 113a, and 114a respectively. The second end 71b of the four first connecting terminals is a free end, used for connecting to an external connector. The first ends 72a of the two first support terminals 72 are soldered to two independent pads 12 in a one-to-one correspondence.

[0067] Figure 4 It shows Figure 1a The connection area in the circuit assembly 100 shown is used for connection with the second type connector 80. Figure 5a Front view of a second type connector 80 provided in an embodiment of this application. Figure 5b for Figure 5a The right view of the second type connector 80 shown. Figure 5c for Figure 5a The bottom view of the second type connector 80 shown.

[0068] like Figure 4 and Figures 5a-5c As shown, when the connector provided on the circuit board 10 is a second type connector 80, the connector is connected to the second area 11b of the shared pad 11 and the via 13. Figure 4 The area marked in black is the soldering area for the second type of connector 80. The first area 11a and the second area 11b do not overlap at least partially because the pin dimensions of the second type of connector are different from those of the first type of connector. The first area 11a and the second area 11b overlap at least partially, allowing the shared pad 11 to have a smaller footprint.

[0069] The second type connector 80 includes a second connecting terminal 81, a second supporting terminal 82, and a second insulating portion 83. The second connecting terminal 81 and the second supporting terminal 82 are disposed on the second insulating portion 83. The second connecting terminal 81 is used to receive external power signals and control signals, and the second supporting terminal 82 is used to stably fix the second type connector 80 to the circuit board 10. The second type connector 80 can be an SMD head type connector, and the second connecting terminal 81 is a connecting pin, with the spacing between the connecting pins being, for example, 2.56 mm.

[0070] Specifically, the first ends 81a of the four second connection terminals 81 are soldered one-to-one to the second region 11b of the shared pad 11. The second regions of the first shared pad 111, the second shared pad 112, the third shared pad 113, and the fourth shared pad 114 are in... Figure 4 These are labeled 111b, 112b, 113b, and 114b respectively. The second end 81b of each of the four second connecting terminals 81 is a free end, used for connecting to an external connector. The first ends 82a of each of the two second support terminals 82 are soldered to the two through holes 13 one-to-one.

[0071] Figure 6 It shows Figure 1a The connection area in the circuit assembly 100 shown is used for connection with the third type connector 90. Figure 7a A front view of a third type connector 90 provided in an embodiment of this application. Figure 7b for Figure 7a The right view of the third type connector 90 shown. Figure 7c for Figure 7a The bottom view of the third type connector 90 shown.

[0072] like Figure 6 and Figures 7a-7c As shown, when the connector provided on the circuit board 10 is a third type connector 90, the connector is connected to the third region 11c of the shared pad 11 and the via 13. Figure 6The area marked in black is the soldering area for the third type connector 00. The first region 11a, the second region 11b, and the third region 11c do not overlap at least partially because the third type connector has different pin dimensions than the first and second type connectors. The fact that the first region 11a, the second region 11b, and the third region 11c overlap at least partially allows the shared pad 11 to have a smaller footprint.

[0073] The third type connector 90 includes a third connecting terminal 91, a third supporting terminal 92, and a third insulating portion 93, with the third connecting terminal 91 and the third supporting terminal 92 disposed on the third insulating portion 93. The third connecting terminal 91 is used to receive external power signals and control signals, and the third supporting terminal 92 is used to stably fix the third type connector 90 to the circuit board 10. The third type connector 90 can be an SMD head type connector, and the third connecting terminal 91 is a connecting pin, with the spacing between the connecting pins being, for example, 2.2 mm.

[0074] Specifically, the first ends 91a of the four third connection terminals 91 are soldered one-to-one to the third region 11c of the shared pad 11. The third regions of the first shared pad 111, the second shared pad 112, the third shared pad 113, and the fourth shared pad 114 are in... Figure 6 These are labeled 111c, 112c, 113c, and 114c respectively. The second end 91b of the four third connecting terminals 91 is a free end, used for connecting to an external connector. The first ends 92a of the two third support terminals 92 are soldered to the two through holes 13 one-to-one.

[0075] In the above embodiments, the circuit board 10 can be compatible with three types of connectors, and the connectors can be selected from one of the first type connector 70, the second type connector 80, and the third type connector 90. However, it is worth noting that in other embodiments, the circuit board 10 may only be compatible with two types of connectors; for example, the connectors may be selected from one of the first type connector 70 and the second type connector 80. Alternatively, the circuit board 10 may only be compatible with four or more types of connectors. The types of connectors are not limited to those in the above examples, and will not be described in detail here.

[0077] like Figure 8aAs shown in Figure 8c, in addition to the circuit board 10, electronic components 20 and connectors similar to those in the above embodiments, the circuit module 100 in this embodiment also includes a housing 30, which can encapsulate the circuit board 10 and electronic components 20 inside it.

[0078] The housing 30 has a light-emitting hole 31 and a connection opening 32. The light-emitting hole 31 is used to emit light emitted by the light source 21, and the connection opening 32 is used to expose the free end of the connector terminal for connecting to an external connector.
