[0002] With the development of science and technology, signal transmission between electronic devices such as mobile phones and tablet computers and external devices is becoming more and more frequent. As a connecting line used to transmit signals in electronic devices, the role of signal transmission lines is becoming more and more important. In the existing technology, the signal transmission line is usually connected to the circuit board using a connector, and is electrically connected to the signal control module on the circuit board through the connector. Specifically, the connector may include a socket and a plug that are connected in a matching manner, one of which is connected to the circuit board, and the other is connected to the signal transmission line. By inserting the plug into the socket, the connection between the signal transmission line and the circuit board can be achieved.

[0003] However, in order to achieve reliable signal transmission, the plug and socket of the connector are usually set to be relatively large, and the space occupied by the plug or socket of the connector on the circuit board is also correspondingly large.

[0023] An embodiment of the present application provides a circuit board assembly, which may include a circuit board and a signal transmission line for transmitting signals. The signal may include but is not limited to a high-frequency signal, a medium-frequency signal, or a low-frequency signal, etc. The embodiment of the present application does not specifically limit the type of signal that the signal transmission line can transmit.

[0024] Reference Figure 1 , showing a schematic diagram of the structure of a circuit board assembly according to an embodiment of the present application, Figure 2 , showing Figure 1 The schematic diagram of the structure of the signal transmission line in the circuit board assembly shown in FIG. Figure 3 , showing Figure 2 A schematic structural diagram of the signal transmission line shown in FIG.

[0025] Specifically, the circuit board assembly may include: a circuit board 2 and a signal transmission line 1; wherein the circuit board 2 is provided with a plug hole 21; the signal transmission line 1 may include a transmission line body 10 and a plug structure 11, the plug structure 11 is connected to the transmission line body 10, and the plug structure 11 is at least partially inserted into the plug hole 21 to connect the signal transmission line 1 to the circuit board 2.

[0026] In the embodiment of the present application, the circuit board assembly is provided with a plug hole 21 on the circuit board 2 and a plug structure 11 on the signal transmission line 1. The signal transmission line 1 can be connected to the circuit board 2 by directly inserting the plug structure 11 into the plug hole 21, thereby avoiding the design of a connector plug or socket on the circuit board 2, saving space on the circuit board 2, and improving the space utilization rate of the circuit board 2.

[0027] Specifically, the transmission line body 10 may include a first grounding layer 101, a first dielectric layer 102, and a first routing layer 103 from the outside to the inside. The first routing layer 103 may be used to transmit signals, and the first routing layer 103 may be made of conductive metals such as copper and gold. The first grounding layer 101 may be used to achieve grounding of the transmission line body 10, and the first grounding layer 101 may be made of conductive metals such as copper and gold. The first dielectric layer 102 may be used to achieve isolation between the first routing layer 103 and the first grounding layer 101, and the first dielectric layer 102 may be made of insulating materials such as plastic and silicone.

[0028] In an embodiment of the present application, the plug-in structure 11 can be set at the end of the transmission line body 10, and the plug-in structure 11 can be electrically connected to the transmission line body 10. By at least partially plugging the plug-in structure 11 into the circuit board 2, the plug-in structure 11 can be electrically connected to the circuit board 2.

[0029] like Figure 1 As shown, the plug-in structure 11 may specifically include: a second grounding layer 111, a second dielectric layer 112 and a second routing layer 113; wherein the second grounding layer 111 is provided with a first groove and a protruding plug-in portion 114, and at least a portion of the plug-in portion 114 is inserted into the plug-in hole 21; the second routing layer 113 is embedded in the first groove, and the second dielectric layer 112 is located between the second routing layer 113 and the second grounding layer 111.

[0030] In the embodiment of the present application, the second grounding layer 111 is electrically connected to the first grounding layer 101 for transmitting signals, the second dielectric layer 112 is connected to the first dielectric layer 102, and the second grounding layer 111 is electrically connected to the first grounding layer 101. A first groove is provided on the side of the second grounding layer 111 close to the circuit board 2, the second wiring layer 113 is embedded in the first groove, and the second dielectric layer 112 is located between the second wiring layer 113 and the second grounding layer 111, and is used to isolate the second wiring layer 113 and the second grounding layer 111. A plug-in portion 114 is also provided on the second grounding layer 111, the plug-in portion 114 protrudes toward the circuit board 2, and is at least partially inserted into the plug-in hole 21 of the circuit board 2, so as to connect the signal transmission line 1 to the circuit board 2, and also make the connection between the plug-in portion 114 and the circuit board 2 more reliable.

[0031] In practical applications, part of the second ground layer 111 may be protruded to form the plug-in portion 114 , which not only simplifies the processing of the plug-in portion 114 but also has little impact on the signal transmission effect of the second wiring layer 113 .

[0032] like Figure 1 As shown, the circuit board assembly may further include: a connector 3; a plug-in hole 21 passing through the circuit board 2, and a plug-in portion 114 is embedded in the plug-in hole 21 from one side of the circuit board 2; a first through hole 1141 is provided on the plug-in portion 114, and the connector 3 is passed through the first through hole 1141, and at least partially extends from a side of the circuit board 2 away from the signal transmission line 1.

[0033] In the embodiment of the present application, since the first through hole 1141 is provided on the plug-in portion 114, after the plug-in portion 114 is inserted into the plug-in hole 21 from one side of the circuit board 2, the connector 3 can be inserted into the first through hole 1141 from one side of the signal transmission line 1, and at least partially extends from the side of the circuit board 2 away from the signal transmission line 1. In practical applications, the portion extending from the side of the circuit board 2 away from the signal transmission line 1 can be connected to other structural members such as the middle frame or mainboard bracket of the electronic device. In this way, on the one hand, the circuit board 2 can be connected to other structural members, and on the other hand, the connection reliability between the signal transmission line 1 and the circuit board 2 can be further increased.

[0034] In practical applications, in order to fix the circuit board 2 on other structural parts of the electronic device, it is necessary to open a hole on the circuit board 2, and use a connector 3 to pass through the opening to connect the circuit board 2 to other structural parts, that is, the circuit board 2 itself needs to open a hole. In the embodiment of the present application, the existing opening on the circuit board 2 can be used as the plug hole 21 described in the embodiment of the present application, and the plug part 114 of the signal transmission line 1 is inserted into the plug hole 21. Finally, the first through hole 1141 of the connector 3 passing through the plug part 114 is used to connect the signal transmission line 1 and the circuit board 2 to other structural parts. In this way, by using the existing opening on the circuit board 2 as the plug hole 21 described in the embodiment of the present application, it is possible to avoid setting up a separate space on the circuit board 2 to set up the plug hole 21, further reducing and saving the space of the circuit board 2, and improving the space utilization rate of the circuit board 2.

[0035] Of course, in practical applications, those skilled in the art may also separately set up a space on the circuit board 2 to set up the plug hole 21, and the embodiment of the present application does not limit this.

[0036] Optionally, the connector 3 includes at least one of a screw, a bolt and a stud, so as to connect the signal transmission line 1 and the circuit board 2 to other structural components of the electronic device through the above-mentioned standard fasteners, thereby reducing the structural cost of the connector 3.

[0037] In some optional embodiments of the present application, the circuit board 2 is provided with a first electrical connection portion 22 at a position corresponding to the second wiring layer 113 , and the first electrical connection portion 22 is electrically connected to the second wiring layer 113 to realize signal transmission between the circuit board 2 and the signal transmission line 1 .

[0038] In practical applications, the circuit board 2 is also provided with a signal processing module 23 ( Figure 1 (not shown), the signal processing module 23 is electrically connected to the first electrical connection portion 22. Since the first electrical connection portion 22 is electrically connected to the second wiring layer 113, the signal transmitted by the signal transmission line 1 can be transmitted to the signal processing module 23 through the first electrical connection portion 22. Specifically, the signal processing module 23 can be used to process the signal transmitted by the signal transmission line 1. For example, when the signal is a radio frequency signal, the signal processing module 23 is a radio frequency module that can process radio frequency signals.

[0039] In some optional embodiments of the present application, the first electrical connection portion 22 at least partially protrudes from the surface of the circuit board 2; when the plug-in portion 114 is inserted into the plug-in hole 21, the first electrical connection portion 22 is at least partially embedded in the first groove and abuts against the second wiring layer 113, so that the connection between the first electrical connection portion 22 and the second wiring layer 113 is relatively stable, so as to further increase the electrical connection stability between the signal transmission line 1 and the circuit board 2.

[0040] Optionally, the first electrical connection portion 22 may be exposed copper on the circuit board 2 , or may be other conductive structures such as a metal conductive sheet. The specific content of the first electrical connection portion 22 may not be limited in the embodiment of the present application.

[0041] Reference Figure 4 , showing a schematic diagram of the structure of another circuit board assembly of an embodiment of the present application, referring to Figure 5 , showing Figure 4 A schematic structural diagram of the signal transmission line of the circuit board assembly shown.

[0042] Specifically, the transmission line body 10 may include a first grounding layer 101, a first routing layer 103 encapsulated in the first grounding layer 101, and a first dielectric layer 102 located between the first grounding layer 101 and the first routing layer 103; the plug-in structure 11 may specifically include a first elastic arm 115 and a second elastic arm 116, the first elastic arm 115 is connected to the first grounding layer 101, the second elastic arm 116 is electrically connected to the first routing layer 103, and at least part of the first elastic arm 115 and the second elastic arm 116 are inserted into the plug-in hole 21 to connect the signal transmission line 1 to the circuit board 2.

[0043] Specifically, the first elastic arm 115 and the second elastic arm 116 can both be made of conductive metals such as copper and silver. The number of the first elastic arms 115 can be two, and the two first elastic arms 115 can be arranged on the same plane and relatively spaced apart. Similarly, the number of the second elastic arms 116 can be two, and the two second elastic arms 116 can be arranged on the same plane and relatively spaced apart. In practical applications, in order to better isolate the first elastic arm 115 and the second elastic arm 116, the plane where the first elastic arm 115 is located and the plane where the second elastic arm 116 is located can be arranged vertically.

[0044] It should be noted that, in actual applications, the number of the first elastic arm 115 and the second elastic arm 116 can also be 1, 3 or 6, etc., and the positions of the first elastic arm 115 and the second elastic arm 116 can also be set according to actual requirements. The embodiment of the present application may not limit the number and position of the first elastic arm 115 and the second elastic arm 116.

[0045] Optionally, the opening of the plug hole 21 can be toward the side wall of the circuit board 2, so that the first elastic arm 115 and the second elastic arm 116 of the signal transmission line 1 can be inserted into the plug hole 21 from the side of the circuit board 2, so as to avoid opening the plug hole 21 on the front or back side of the circuit board 2 to affect the layout of other electronic components on the circuit board 2, save space on the front and back sides of the circuit board 2, and further improve the space utilization of the circuit board 2.

[0046] In some optional embodiments of the present application, the socket 21 may specifically include a first socket 211 and a second socket 212 that are connected; wherein the first socket 211 is close to the side wall of the circuit board 2, and the diameter of the first socket 211 is smaller than the diameter of the second socket 212; a second electrical connection portion and a third electrical connection portion are provided on the side wall of the second socket 212, the first elastic arm 115 is supported against the second electrical connection portion, and the second elastic arm 116 is supported against the third electrical connection portion.

[0047] Specifically, since the first plug hole 211 is close to the side wall of the circuit board 2, the first elastic arm 115 and the second elastic arm 116 can be first inserted into the first plug hole 211, and then inserted into the second plug hole 212 through the first plug hole 211. Since the diameter of the first plug hole 211 is relatively small, the first plug hole 211 can better limit the transmission line body 10 to prevent the transmission line body 10 from shaking in the first plug hole 211. The first elastic arm 115 and the second elastic arm 116 can be inserted into the second plug hole 212 and abut against the side wall of the second plug hole 212. Since the diameter of the second plug hole 212 is larger than the diameter of the first plug hole 211, when the first elastic arm 115 and the second elastic arm 116 are inserted into the second plug hole 212 and abut against the side wall of the second plug hole 212, it is difficult for the first elastic arm 115 and the second elastic arm 116 to slide from the second plug hole 212 into the first plug hole 211. In this way, the connection reliability between the first elastic arm 115 and the second elastic arm 116 and the second plug hole 212 can be further improved, thereby further improving the connection reliability between the signal transmission line 1 and the circuit board 2.

[0048] In the embodiment of the present application, a second electrical connection portion and a third electrical connection portion are provided on the side wall of the second jack 212, wherein the second electrical connection portion can be electrically connected to the ground layer on the circuit board 2, and the third electrical connection portion can be electrically connected to the signal processing module 23 on the circuit board 2. The first elastic arm 115 abuts against the second electrical connection portion to achieve electrical connection between the first ground layer 101 and the ground layer on the circuit board 2, and the second elastic arm 116 abuts against the third electrical connection portion to achieve electrical connection between the first routing layer 103 and the signal processing module 23, thereby achieving signal transmission.

[0049] It should be noted that the second electrical connection part and the third electrical connection part can be exposed copper on the circuit board 2, or can be other conductive structures such as metal conductive sheets. The embodiment of the present application does not limit the specific contents of the second connection part and the third electrical connection part.

[0050] In summary, the circuit board assembly described in the embodiment of the present application can at least include the following advantages:

[0051] In the embodiment of the present application, the circuit board assembly is provided with a plug hole on the circuit board and a plug structure on the signal transmission line. The signal transmission line can be connected to the circuit board by directly inserting the plug structure into the plug hole, thereby avoiding the design of a plug or socket of a connector on the circuit board, saving space on the circuit board, and improving the space utilization rate of the circuit board.
