Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a flexible connection device and an electronic device. Background Technology

[0002] Flexible interconnection devices can be used in electronic devices such as computing devices and communication devices to achieve electrical interconnection between different components.

[0003] In related technologies, flexible connection devices typically include cables and connectors located at both ends of the cables. The cables are connected to the connectors by soldering to achieve electrical connection between the cables and connectors. However, the transmission performance of these flexible connection devices still needs improvement. Utility Model Content

[0004] This application provides a flexible connection device and an electronic device, which can improve the transmission performance of the flexible connection device.

[0005] A first aspect of this application provides a flexible connection device, which includes a first support plate, a second support plate, and a first flexible circuit board. The first support plate includes a first side surface located on one side of its thickness direction. The second support plate includes a second side surface located on one side of its thickness direction. The first flexible circuit board includes a first insertion terminal and a second insertion terminal. The first insertion terminal is fixedly connected to the first side surface, and a first conductive contact is provided on the surface of the first insertion terminal facing away from the first side surface. The second insertion terminal is fixedly connected to the second side surface, and a second conductive contact is provided on the surface of the second insertion terminal facing away from the second side surface. The first flexible circuit board has a first printed circuit, and the first and second conductive contacts are electrically connected through the first printed circuit.

[0006] The flexible connection device provided in this application embodiment has a first conductive contact and a second conductive contact electrically connected through a first printed circuit of a first flexible circuit board. This can improve the impedance continuity between the first conductive contact and the second conductive contact, that is, improve the impedance continuity between the input and output terminals of the flexible connection device. This can improve the transmission performance of the flexible connection device, which is beneficial for the disassembly, assembly and maintenance of electronic equipment, while improving the interaction performance between the two components connected by the flexible connection device.

[0007] In addition, the first flexible circuit board itself has a small thickness and is easy to bend and deform, which makes it easy to arrange in a compact and limited space. This makes the arrangement of the flexible connection device more flexible, which helps to shorten the transmission length between the input and output ends of the flexible connection device, thereby reducing the transmission loss between the input and output ends of the flexible connection device and improving the interaction performance between the two components connected by the flexible connection device.

[0008] Furthermore, the first flexible circuit board can integrate a large number of circuits while maintaining a relatively small thickness, resulting in a simpler structure within the installation space. This minimizes airflow obstruction and improves the efficiency of air-cooling. The simplified structure within the installation space also reduces the likelihood of malfunctions caused by components rubbing against the flexible connection device.

[0009] Furthermore, flexible connection devices are formed by using flexible circuit boards and support plates. The molding of flexible connection devices is relatively easy and the manufacturing cost is low.

[0010] In addition, the flexible connection device formed by the flexible circuit board and the support plate also has good vibration resistance, impact resistance and thermal stability, which makes the connection between the two components connected by the flexible connection device more reliable and stable.

[0011] In some possible implementations, the first plug-in terminal is insulated from the first support plate, and the second plug-in terminal is insulated from the second support plate. In this case, no electrical connection is required between the first and second support plates and the first flexible circuit board, making the assembly of the first and second support plates with the first flexible circuit board easier and the flexible connection device easier to form and less expensive. Furthermore, since both the first and second support plates are insulated from the first flexible circuit board, the electrical interaction of the first flexible circuit board is less susceptible to the influence of the first and second support plates.

[0012] In some possible implementations, the first plug-in end is bonded to the first side surface via a first adhesive layer, and the second plug-in end is bonded to the second side surface via a second adhesive layer. Both the first and second adhesive layers are insulating layers. This facilitates the insulating and fixed connection between the first plug-in end and the first side surface, and between the second plug-in end and the second side surface. The assembly of the first and second support plates with the first flexible circuit board is also easier, and the flexible connection device is easier to form and has a lower cost.

[0013] In some possible implementations, the flexible connection device further includes a first connector housing and a second connector housing. The first connector housing is sleeved on the outside of the first support plate and the first plug-in end, and is fixedly connected to the first support plate and the first plug-in end. The second connector housing is sleeved on the outside of the second support plate and the second plug-in end, and is fixedly connected to the second support plate and the second plug-in end. This facilitates a stable connection between the flexible connection device and the corresponding connector.

[0014] In some possible implementations, the first support plate includes a first side and a second side, which are respectively located on both sides of the first support plate in the width direction of the first conductive contact. At least one of the first side and the second side has a first snap-fit ​​structure, and the inner wall of the first connector housing has a first mating structure. The first snap-fit ​​structure snaps into the first mating structure.

[0015] In this way, the cooperation between the first snap-fit ​​structure and the first mating structure prevents the first support plate from shifting relative to the first connector housing, thereby preventing the first plug-in end from shifting relative to the first connector housing. This results in better structural stability of the flexible connection device and better electrical contact stability of the first conductive contact. Furthermore, the first snap-fit ​​structure is located on at least one of the first and second sides, ensuring that while the first support plate is less likely to shift relative to the first connector housing, the snap-fit ​​structure does not significantly affect the placement of the first conductive contact and the first flexible circuit board.

[0016] In some possible implementations, the second support plate includes a third side and a fourth side, which are located on opposite sides of the second support plate in the width direction of the second conductive contact. At least one of the third side and the fourth side has a second snap-fit ​​structure, and the inner wall of the second connector housing has a second mating structure. The second snap-fit ​​structure snaps into the second mating structure.

[0017] In this way, the cooperation between the second snap-fit ​​structure and the second mating structure prevents the second support plate from shifting relative to the second connector housing, thereby preventing the second insertion end from shifting relative to the second connector housing. This results in better structural stability of the flexible connection device and better electrical contact stability of the second conductive contact. Furthermore, the second snap-fit ​​structure is located on at least one of the third and fourth sides, ensuring that while the second support plate is less likely to shift relative to the second connector housing, the placement of the second snap-fit ​​structure does not significantly affect the placement of the second conductive contact and the first flexible circuit board.

[0018] In some possible implementations, the flexible leveling device further includes a second flexible circuit board. The first support plate also includes a third side surface, with the first and third side surfaces located on opposite sides of the thickness direction of the first support plate. The second support plate also includes a fourth side surface, with the second and fourth side surfaces located on opposite sides of the thickness direction of the second support plate. The second flexible circuit board includes a third insertion terminal and a fourth insertion terminal. The third insertion terminal is fixedly connected to the third side surface, and a third conductive contact is provided on the surface of the third insertion terminal facing away from the third side surface. The fourth insertion terminal is fixedly connected to the fourth side surface, and a fourth conductive contact is provided on the surface of the fourth insertion terminal facing away from the fourth side surface. The second flexible circuit board has second printed circuitry, and the third and fourth conductive contacts are electrically connected through the second printed circuitry.

[0019] In this way, electrical interaction can be achieved through conductive contacts located on both sides of the first and second support plates. While keeping the size of the flexible connection device small, it can also have more transmission channels, which is conducive to multi-channel electrical interaction between the two components.

[0020] In some possible implementations, the first support plate and the second support plate are located on the same side of the thickness direction of the first flexible circuit board and on the same side of the thickness direction of the second flexible circuit board.

[0021] In this way, the assembly of the first flexible circuit board, the second flexible circuit board, the first support plate, and the second support plate is more convenient.

[0022] In some possible implementations, the first flexible circuit board further includes a first connecting portion located between the first plug-in terminal and the second plug-in terminal, the first plug-in terminal and the second plug-in terminal being connected via the first connecting portion. The second flexible circuit board further includes a second connecting portion located between the third plug-in terminal and the fourth plug-in terminal, the third plug-in terminal and the fourth plug-in terminal being connected via the second connecting portion. The second connecting portion overlaps with and is fixedly connected to the surface of the first connecting portion on one side of the thickness direction of the first flexible circuit board.

[0023] In this way, the flexible connecting device has a smaller width, making it easier to arrange. In addition, the first connecting part and the second connecting part fit tightly and are not easy to shift, which makes it easy for the flexible connecting device to be arranged through a small space, and the arrangement of the flexible connecting device is more flexible.

[0024] A second aspect of this application provides an electronic device including a first connector, a second connector, and a flexible connection device as described in any of the above embodiments. A first insertion end of the flexible connection device and a first support plate of the flexible connection device are inserted into the first connector, and a first conductive contact of the flexible connection device is in electrical contact with the first connector. A second insertion end of the flexible connection device and a second support plate of the flexible connection device are inserted into the second connector, and a second conductive contact of the flexible connection device is in electrical contact with the second connector.

[0025] In some possible implementations, the electronic device further includes a base plate, a first component, a second component, and a third component. The first, second, and third components are all fixedly connected to the base plate, with the third component located between the first and second components. The first component has a first connector, and the second component has a second connector. A gap exists between the third component and the base plate, and a first flexible circuit board of the flexible connection device passes through this gap.

[0026] This allows for wiring to be routed using the gap between the third component and the base plate, improving space utilization in the installation area. Additionally, it shortens the transmission path between the first and second connectors, reducing transmission loss and improving their interaction performance. Furthermore, the third component can partially shield the flexible connection device, preventing it from rubbing against other components and resulting in a cleaner structure within the installation space.

[0054] Figure 1 This is a schematic diagram of an electronic device provided in an embodiment of this application.

[0055] like Figure 1 As shown, the electronic device may include a housing 100 and a first component 200 disposed within the housing 100. The housing 100 includes a top cover 110 and a bottom cover 120. The top cover 110 covers the upper end of the bottom cover 120, and the bottom cover 120 and the top cover 110 enclose an installation space. The first component 200 is disposed within the installation space and is fixedly connected to the bottom cover 120.

[0056] Specifically, the bottom shell 120 includes a bottom plate 121, a first panel 122, a second panel 123, and a first side plate 124 (e.g., ...). Figure 2 (as shown) and the second side plate 125 (as shown) Figure 2 As shown in the diagram, the first panel 122 and the second panel 123 are arranged opposite each other and are fixedly connected to the front and rear ends of the base plate 121, respectively. The first side panel 124 and the second side panel 125 are arranged opposite each other and are fixedly connected to the left and right sides of the base plate 121, respectively. The base plate 121 and the top cover 110 are arranged opposite each other vertically. The upper ends of the first panel 122, the second panel 123, the first side panel 124, the second side panel 125 and the top cover 110 are fixedly connected to the top cover 110. The base plate 121, the first panel 122, the second panel 123, the first side panel 124, the second side panel 125 and the top cover 110 surround and form an installation space. The first component 200 is fixedly connected to the base plate 121.

[0057] In some examples, the first component 200 includes a first circuit board 210 and a first device 220, the first circuit board 210 being fixedly connected to the base plate 121, the first device 220 being disposed on the first circuit board 210, and the first device 220 being electrically connected to the first circuit board 210.

[0065] Figure 2 This is a schematic diagram of another electronic device provided in an embodiment of this application. Wherein, Figure 2 This is a top view after removing the top cover 110.

[0066] like Figure 2 As shown, the electronic device also includes a first connector 510, a second connector 520, and a flexible connection device 600. One end of the flexible connection device 600 is inserted into the first connector 510 and makes electrical contact with the first connector 510. The other end of the flexible connection device 600 is inserted into the second connector 520 and makes electrical contact with the second connector 520. The first connector 510 and the second connector 520 are electrically connected through the flexible connection device 600. The two components can be electrically connected through the first connector 510, the flexible connection device 600, and the second connector 520. The flexible connection device 600 can be quickly plugged in and out of the first connector 510 and the second connector 520, making the disassembly, assembly, and maintenance of the electronic device more convenient.

The first device 220 can be electrically connected to the second component 300 through the first connector 510, the flexible connection device 600 and the second connector 520 to realize the electrical interconnection between the first device 220 and the second component 300.

[0070] Figure 3 This is a schematic diagram of yet another electronic device provided in an embodiment of this application. Wherein, Figure 3 This is a top view after removing the top cover 110.

[0071] like Figure 3 As shown, in some examples, the first component 200 further includes a second device 230, which is disposed on the first circuit board 210 and electrically connected to the first circuit board 210. Exemplarily, the second device 230 may include, but is not limited to, a processor, memory, network card, etc.

[0072] In some examples, the first circuit board 210 is provided with a first connector 510 and a second connector 520. The first device 220 is electrically connected to the first connector 510 through the first circuit board 210, and the second device 230 is electrically connected to the first device 230 through the first circuit board 210. The first device 220 and the second device 230 are electrically connected through the first connector 510, the flexible connection device 600 and the second connector 520 to realize the electrical interconnection between the first device 220 and the second device 230.

[0073] For example, the first circuit board 210 is fixed and electrically connected to the first connector 510 and the second connector 520.

[0074] Figure 4 This is a schematic diagram of a flexible connection device provided in an embodiment of this application.

[0075] like Figure 4As shown, the flexible connection device 600 includes a first support plate 610, a second support plate 620, and a first flexible circuit board 630. The first support plate 610 includes a first side 611 and a third side 612, which are located on opposite sides of the thickness direction of the first support plate 610. The second support plate 620 includes a second side 621 and a fourth side 622, which are located on opposite sides of the thickness direction of the second support plate 620.

[0076] The first flexible circuit board 630 includes a first insertion terminal 631 and a second insertion terminal 632.

[0077] The first plug-in end 631 is fixedly connected to the first side surface 611. The first plug-in end 631 is located on one side of the thickness direction of the first support plate 610. The surface of the first plug-in end 631 facing away from the first side surface 611 has a first conductive contact 6311. The first plug-in end 631 and the first support plate 610 are used to form a first connector structure. The first connector structure is plugged into the first connector 510, and the first conductive contact 6311 is in electrical contact with the first connector 510. The first support plate 610 is used to provide strength and thickness to meet the plugging requirements of the first connector structure and the first connector 510. The first support plate 610 can provide effective support for the first plug-in end 631, so that the first plug-in end 631 is not easily bent or deformed during the insertion and removal of the first connector structure.

[0078] The second insertion end 632 is fixedly connected to the second side surface 621. The second insertion end 632 is located on one side of the second support plate 620 in the thickness direction. The surface of the second insertion end 632 facing away from the second side surface 621 has a second conductive contact 6321. The second insertion end 632 and the second support plate 620 are used to form a second connector structure. The second connector structure is inserted into the second connector 520, and the second conductive contact 6321 is in electrical contact with the second connector 520. The second support plate 620 is used to provide strength and thickness to meet the insertion requirements of the second connector structure and the second connector 520. The second support plate 620 can provide effective support for the second insertion end 632, making it less prone to bending and deformation during the insertion and removal of the second connector structure.

[0079] The first flexible circuit board 630 has a first printed circuit 634, and a first conductive contact 6311 and a second conductive contact 6321 are electrically connected through the first printed circuit 634. The first conductive contact 6311, the second conductive contact 6321 and the first printed circuit 634 are all formed by circuit board manufacturing process, and the first conductive contact 6311 and the second conductive contact 6321 are located on the surface of the first flexible circuit board 630.

[0080] In this way, the first conductive contact 6311 and the second conductive contact 6321 are electrically connected through the first printed circuit 634 of the first flexible circuit board 630. The first support plate 610 and the second support plate 620 do not need to play the role of circuit conduction. The electrical connection between the first conductive contact 6311 and the second conductive contact 6321 is not achieved through the transition between the first support plate 610 and the second support plate 620. This allows for better impedance continuity between the first conductive contact 6311 and the second conductive contact 6321. In other words, it allows for better impedance continuity between the input and output terminals of the flexible connection device 600. Consequently, it allows for better transmission performance of the flexible connection device 600. This facilitates the disassembly, assembly, and maintenance of electronic equipment while improving the interaction performance between the two components connected by the flexible connection device 600. For example, when the flexible connection device 600 is used to transmit high-speed signals, the good continuity of impedance between the input and output terminals of the flexible connection device 600 results in good performance in terms of crosstalk and return loss of high-speed signals, and can improve the interaction performance of high-speed signals between two components connected by the flexible connection device 600.

[0081] Furthermore, the first flexible circuit board 630 has a small thickness and is easy to bend and deform, making it easy to arrange in a compact and limited space. This allows for more flexible placement of the flexible connection device 600, which helps to shorten the transmission length between the input and output ends of the flexible connection device 600, thereby reducing the transmission loss between the input and output ends of the flexible connection device 600 and improving the interaction performance between the two components connected by the flexible connection device 600.

[0082] Furthermore, the first flexible circuit board 630 can integrate a large number of circuits and has a small thickness, which allows for a simpler structure within the installation space, resulting in less obstruction of airflow and thus improving the energy efficiency of air cooling. The simpler structure within the installation space also reduces the likelihood of malfunctions caused by components within the installation space rubbing against the flexible connecting device 600.

[0083] Furthermore, the flexible connection device 600 is formed by a flexible circuit board and a support plate. The flexible connection device 600 is relatively easy to form and has a low manufacturing cost.

[0084] In addition, the flexible connection device 600 formed by the flexible circuit board and the support plate also has good vibration resistance, impact resistance and thermal stability, which makes the connection between the two components connected by the flexible connection device 600 more reliable and stable.

[0085] For example, the first plug-in end 631 and the first support plate 610 are plugged into the first connector 510, and the second plug-in end 632 and the second support plate 620 are plugged into the second connector 520.

[0086] For example, the first conductive contact 6311 and the second conductive contact 6321 are gold fingers.

[0087] For example, the first conductive contact 6311, the second conductive contact 6321, and the first flexible circuit board 630 are an integral structure.

[0088] For example, the first plug-in terminal 631 has a plurality of first conductive contacts 6311 arranged in a row along the width direction of the first conductive contacts 6311. The length direction of the first conductive contacts 6311 is the insertion / removal direction of the first connector structure, and the width direction of the first conductive contacts 6311 is a direction perpendicular to the insertion / removal direction of the first connector structure.

[0089] For example, the second plug-in terminal 632 has a plurality of second conductive contacts 6321 arranged in a row along the width direction of the second conductive contacts 6321. The length direction of the second conductive contacts 6321 is the insertion / removal direction of the second connector structure, and the width direction of the second conductive contacts 6321 is a direction perpendicular to the insertion / removal direction of the second connector structure.

[0090] For example, the thickness of the first flexible circuit board 630 can be greater than or equal to 0.2 mm and less than or equal to 0.5 mm. For instance, the thickness of the first flexible circuit board 630 can be 0.4 mm.

[0091] For example, the first connector structure and the second connector structure may include, but are not limited to, MCIO connector structures, UBC connector structures, etc. Correspondingly, the first connector 510 and the second connector 520 may include, but are not limited to, MCIO connectors, UBC connectors, etc.

[0092] When the first connector structure and the second connector structure are MCIO connector structures, the thickness of the first connector structure and the second connector structure can be 1.57mm.

[0093] For example, the first flexible circuit board 630 also includes a first connecting portion 633 located between the first plug-in end 631 and the second plug-in end 632, the first plug-in end 631 and the second plug-in end 632 being connected through the first connecting portion 633.

[0094] For example, the first flexible circuit board 630 may include one or more first plug-in terminals 631, the flexible connection device 600 includes a first support plate 610 corresponding to the first plug-in terminals 631, the first plug-in terminals 631 are fixedly connected to the first side surface 611 of the corresponding first support plate 610, and the flexible connection device 600 may form one or more first connector structures.

[0095] For example, the first flexible circuit board 630 may include one or more second plug-in terminals 632, the flexible connection device 600 includes a second support plate 620 corresponding to each of the second plug-in terminals 632, the second plug-in terminals 632 are fixedly connected to the second side 621 of the corresponding second support plate 620, and the flexible connection device 600 may form one or more second connector structures.

[0096] In some possible implementations, the first plug-in terminal 631 is insulated from the first support plate 610, and the second plug-in terminal 632 is insulated from the second support plate 620. In this case, no electrical connection is required between the first support plate 610, the second support plate 620, and the first flexible circuit board 630, making the assembly of the first support plate 610, the second support plate 620, and the first flexible circuit board 630 easier and cheaper. Furthermore, since both the first support plate 610 and the second support plate 620 are insulated from the first flexible circuit board 630, the electrical interaction of the first flexible circuit board 630 is less susceptible to the influence of the first support plate 610 and the second support plate 620.

[0097] In some possible implementations, the first plug end 631 is bonded to the first side surface 611 by a first adhesive layer 651, and the second plug end 632 is bonded to the second side surface 621 by a second adhesive layer 652. Both the first adhesive layer 651 and the second adhesive layer 652 are insulating layers.

[0098] This facilitates the insulation and fixed connection between the first plug-in end 631 and the first side 611, and between the second plug-in end 632 and the second side 621. The assembly difficulty of the first support plate 610 and the second support plate 620 with the first flexible circuit board 630 is relatively low, and the flexible connection device 600 is easier to form and has a lower cost.

[0099] In some examples, the first adhesive layer 651 and the second adhesive layer 652 can both be structural layers formed by hot pressing a prepreg. The first insertion end 631 and the first support plate 610, and the second insertion end 632 and the second support plate 620 can be fixedly connected by hot pressing.

[0100] In other examples, the first adhesive layer 651 and the second adhesive layer 652 can be adhesive backing layers, that is, the first insertion end 631 and the first side 611, and the second insertion end 632 and the second side 621 can be bonded by adhesive backing.

[0101] For example, both the first support plate 610 and the second support plate 620 are insulating plates, that is, the materials of the first support plate 610 and the second support plate 620 are insulating materials.

[0102] For example, the first support plate 610 and the second support plate 620 may be, but are not limited to, resin plates, fiberglass plates, plastic plates, etc.

[0103] In some examples, the first support plate 610 and the second support plate 620 are located on both sides of the thickness direction of the first flexible circuit board 630.

[0104] Figure 5 This is a schematic diagram of another flexible connection device provided in an embodiment of this application.

[0105] like Figure 5 As shown, in some other examples, the first support plate 610 and the second support plate 620 are located on the same side of the thickness direction of the first flexible circuit board 630.

[0106] like Figure 5 As shown, in some possible embodiments, the flexible connection device 600 further includes a first connector housing 660 and a second connector housing 670.

[0107] The first connector housing 660 is sleeved on the outside of the first support plate 610 and the first plug end 631 and is fixedly connected to the first support plate 610 and the first plug end 631. The first connector housing 660, the first support plate 610 and the first plug end 631 are used to form the first connector structure. The first connector housing 660 is used to plug into the first connector 510 so that the first connector structure is fixed to the first connector 510.

[0108] The second connector housing 670 is sleeved on the outside of the second support plate 620 and the second plug-in end 632 and is fixedly connected to the second support plate 620 and the second plug-in end 632. The second connector housing 670, the second support plate 620 and the second plug-in end 632 are used to form the second connector structure. The second connector housing 670 is used to plug into the second connector 520 so that the second connector structure is fixed to the second connector 520.

[0109] This facilitates a secure connection between the flexible connection device 600 and the corresponding connector.

[0110] For example, the first connector housing 660 includes a first half-shell and a second half-shell disposed opposite to each other. The first half-shell and the second half-shell can be fixedly connected by means of adhesive, snap-fit ​​or other means. The first support plate 610 and the first plug end 631 are located between the first half-shell and the second half-shell. The first support plate 610 and the first plug end 631 can be pressed and fixed by the first half-shell and the second half-shell.

[0111] For example, the second connector housing 670 includes a third half-shell and a fourth half-shell disposed opposite to each other. The third half-shell and the fourth half-shell can be fixedly connected by means of adhesive, snap-fit ​​or other means. The second support plate 620 and the second plug-in end 632 are located between the third half-shell and the fourth half-shell. The second support plate 620 and the second plug-in end 632 can be pressed and fixed by the third half-shell and the fourth half-shell.

[0112] Figure 6 This is a schematic diagram of a flexible connection device provided in an embodiment of this application at a first support plate.

[0113] like Figure 5 , Figure 6 As shown, in some possible embodiments, the first support plate 610 includes a first side and a second side, which are respectively located on both sides of the first support plate 610 in the width direction of the first conductive contact 6311. At least one of the first side and the second side has a first snap-fit ​​structure 613. The inner wall of the first connector housing 660 has a first mating structure. The first snap-fit ​​structure 613 snaps into the first mating structure and the first snap-fit ​​structure mates with the first mating structure to limit the relative movement of the first support plate 610 and the first connector housing 660 in the insertion and removal direction of the first connector structure.

[0114] Thus, during insertion and removal of the first connector structure, the cooperation between the first snap-fit ​​structure 613 and the first mating structure prevents the first support plate 610 from shifting relative to the first connector housing 660, thereby preventing the first insertion end 631 from shifting relative to the first connector housing 660. This results in better structural stability of the first connector structure and better electrical contact stability of the first conductive contact 6311. Furthermore, the first snap-fit ​​structure 613 is located on at least one of the first and second sides, ensuring that while the first support plate 610 is less likely to shift relative to the first connector housing 660, the placement of the first snap-fit ​​structure 613 does not significantly affect the placement of the first conductive contact 6311 and the first flexible circuit board 630.

[0115] For example, both the first and second sides are provided with a first snap-fit ​​structure 613, so that the first support plate 610 and the first connector housing 660 are snapped together more stably.

[0116] For example, one of the first snap-fit ​​structure 613 and the first mating structure is a snap ridge and the other is a snap groove. For instance, the first snap-fit ​​structure 613 is a snap ridge and the first mating structure is a snap groove.

[0117] For example, the first plug-in end 631 has a protruding structure or a recessed structure opposite to the first snap-fit ​​structure 613.

[0118] For example, the first snap-fit ​​structure 613 is a slot, and the first insertion end 631 has a notch structure at the position opposite to the first snap-fit ​​structure 613.

[0119] For example, the first snap-fit ​​structure 613 is a snap-fit ​​edge, and the first plug-in end 631 may cover the part of the first side 611 located in the first snap-fit ​​structure 613, or it may not cover the part of the first side 611 located in the first snap-fit ​​structure 613.

[0120] For example, the first mating structure includes a first sub-matting structure located on the inner wall of the first half-shell and a second sub-matting structure located on the inner wall of the second half-shell, and the first snap-fit ​​structure 613 is snap-fitted with both the first sub-matting structure and the second sub-matting structure.

[0121] In some possible implementations, the second support plate 620 includes a third side and a fourth side, which are respectively located on both sides of the second support plate 620 in the width direction of the second conductive contact 6321. At least one of the third side and the fourth side has a second snap-fit ​​structure 623. The inner wall of the second connector housing 670 has a second mating structure. The second snap-fit ​​structure 623 snaps into the second mating structure and engages with the second mating structure to limit the relative movement of the second support plate 620 and the second connector housing 670 in the insertion and removal direction of the second connector structure.

[0122] Thus, during the insertion and removal of the second connector structure, the cooperation between the second snap-fit ​​structure 623 and the second mating structure prevents the second support plate 620 from shifting relative to the second connector housing 670, thereby preventing the second insertion end 632 from shifting relative to the second connector housing 670. This results in better structural stability of the second connector structure and better electrical contact stability of the second conductive contact 6321. Furthermore, the second snap-fit ​​structure 623 is located on at least one of the third and fourth sides, ensuring that while the second support plate 620 is less likely to shift relative to the second connector housing 670, the placement of the second snap-fit ​​structure 623 does not significantly affect the placement of the second conductive contact 6321 and the first flexible circuit board 630.

[0123] For example, the third and fourth sides are provided with a second snap-fit ​​structure 623, which makes the snap-fit ​​between the second support plate 620 and the second connector housing 670 more stable.

[0124] For example, one of the second snap-fit ​​structure 623 and the second mating structure is a snap ridge and the other is a snap groove. For instance, the second snap-fit ​​structure 623 is a snap ridge and the second mating structure is a snap groove.

[0125] For example, the second insertion end 632 has a protruding structure or a recessed structure opposite to the second snap-fit ​​structure 623.

[0126] For example, the second snap-fit ​​structure 623 is a slot, and the second insertion end 632 has a notch structure at the position opposite to the second snap-fit ​​structure 623.

[0127] For example, the second snap-fit ​​structure 623 is a snap-fit ​​edge, and the second plug-in end 632 may cover the part of the second side 621 located in the second snap-fit ​​structure 623, or it may not cover the part of the second side 621 located in the second snap-fit ​​structure 623.

[0128] For example, the second mating structure includes a third sub-matting structure located on the inner wall of the third half-shell and a fourth sub-matting structure located on the inner wall of the fourth half-shell, and the second snap-fit ​​structure 623 snaps into both the third sub-matting structure and the fourth sub-matting structure.

[0129] Figure 7 This is a schematic diagram of another flexible connection device provided in an embodiment of this application.

[0130] like Figure 7 As shown, in some possible embodiments, the flexible connection device 600 further includes a second flexible circuit board 640. The second flexible circuit board 640 includes a third insertion terminal 641 and a fourth insertion terminal 642.

[0131] The third plug-in end 641 is fixedly connected to the third side surface 612. The first support plate 610 is located between the first plug-in end 631 and the third plug-in end 641. The first plug-in end 631 and the third plug-in end 641 are located on opposite sides of the thickness direction of the first support plate 610. The surface of the third plug-in end 641 facing away from the third side surface 612 has a third conductive contact 6411. The first plug-in end 631, the third plug-in end 641, and the first support plate 610 are used to form the first connector structure. The first conductive contact 6311 and the third conductive contact 6411 are in electrical contact with the first connector 510. The first support plate 610 can also provide effective support for the third plug-in end 641, making it less prone to bending and deformation during the insertion and removal of the first connector structure.

[0132] The fourth plug-in terminal 642 is fixedly connected to the fourth side surface 622. The second support plate 620 is located between the second plug-in terminal 632 and the fourth plug-in terminal 642. The second plug-in terminal 632 and the fourth plug-in terminal 642 are located on opposite sides of the thickness direction of the second support plate 620. The surface of the fourth plug-in terminal 642 facing away from the fourth side surface 622 has a fourth conductive contact 6421. The second plug-in terminal 632, the fourth plug-in terminal 642, and the second support plate 620 are used to form the second connector structure. The second conductive contact 6321 and the fourth conductive contact 6421 are in electrical contact with the second connector 520. The second support plate 620 can also provide effective support for the fourth plug-in terminal 642, making it less prone to bending and deformation during the insertion and removal of the second connector structure.

[0133] The second flexible circuit board 640 has a second printed circuit 644, and a third conductive contact 6411 and a fourth conductive contact 6421 are electrically connected through the second printed circuit 644. The third conductive contact 6411, the fourth conductive contact 6421, and the second printed circuit 644 are all formed by circuit board manufacturing processes, and the third conductive contact 6411 and the fourth conductive contact 6421 are located on the surface layer of the second flexible circuit board 640.

[0134] In this way, electrical interaction can be achieved through the conductive contacts located on both sides of the first support plate 610 and the second support plate 620. While the size of the flexible connection device 600 is small, it can have more transmission channels, which is conducive to multi-channel electrical interaction between the two components.

[0135] When the flexible connection device 600 includes a second flexible circuit board 640, the first insertion end 631, the third insertion end 641 and the first support plate 610 are inserted into the first connector 510, and the second insertion end 632, the fourth insertion end 642 and the second support plate 620 are inserted into the second connector 520.

[0136] For example, the third conductive contact 6411 and the fourth conductive contact 6421 are gold fingers.

[0137] For example, the third conductive contact 6411, the fourth conductive contact 6421, and the second flexible circuit board 640 are integrated into one structure.

[0138] For example, the third plug-in terminal 641 has a plurality of third conductive contacts 6411 arranged in a row along the width direction of the third conductive contacts 6411. The length direction of the third conductive contacts 6411 is the insertion / removal direction of the first connector structure, and the width direction of the third conductive contacts 6411 is a direction perpendicular to the insertion / removal direction of the first connector structure.

[0139] For example, the fourth plug-in terminal 642 has a plurality of fourth conductive contacts 6421 arranged in a row along the width direction of the fourth conductive contacts 6421. The length direction of the fourth conductive contacts 6421 is the insertion / removal direction of the second connector structure, and the width direction of the fourth conductive contacts 6421 is a direction perpendicular to the insertion / removal direction of the second connector structure.

[0140] For example, the thickness of the second flexible circuit board 640 can be greater than or equal to 0.2 mm and less than or equal to 0.5 mm. For instance, the thickness of the second flexible circuit board 640 can be 0.4 mm.

[0141] For example, the second flexible circuit board 640 also includes a second connecting portion 643 located between the third plug-in end 641 and the fourth plug-in end 642, the third plug-in end 641 and the fourth plug-in end 642 being connected through the second connecting portion 643.

[0142] In some possible implementations, the second connecting portion 643 overlaps with and is fixedly connected to the surface of the first connecting portion 633 on the thickness side of the first flexible circuit board 630.

[0143] In this way, the flexible connecting device 600 has a smaller width, making it easier to arrange. In addition, the first connecting part 633 and the second connecting part 643 fit tightly and are not easy to shift, which makes it easy for the flexible connecting device 600 to be arranged through a small space, and the arrangement of the flexible connecting device 600 is more flexible.

[0144] For example, the orthographic projection of the second connecting portion 643 onto the first connecting portion 633 is located within the first connecting portion 633.

[0145] Of course, in some other examples, the second connecting part 643 and the first connecting part 633 may not be fixed.

[0146] like Figure 7 As shown, in some possible embodiments, the first support plate 610 and the second support plate 620 are located on the same side of the thickness direction of the first flexible circuit board 630 and on the same side of the thickness direction of the second flexible circuit board 640.

[0147] In this way, the assembly of the first flexible circuit board 630, the second flexible circuit board 640, the first support plate 610 and the second support plate 620 is more convenient.

[0148] In some examples where the first flexible circuit board 630 includes a plurality of first plug-in terminals 631, a third plug-in terminal 641 is fixedly connected to a first support plate 610 corresponding to one or more of the first plug-in terminals 631. That is, one or more of the first connector structures may include a third plug-in terminal 641.

[0149] In some examples where the first flexible circuit board 630 includes a plurality of second plug-in terminals 632, a second support plate 620 corresponding to one or more of the second plug-in terminals 632 is fixedly connected to a fourth plug-in terminal 642. That is, one or more of the second connector structures may include a fourth plug-in terminal 642.

[0150] In some possible implementations, the third plug-in terminal 641 is insulated from the first support plate 610, and the fourth plug-in terminal 642 is insulated from the second support plate 620. In this case, no electrical connection is required between the first support plate 610, the second support plate 620, and the second flexible circuit board 640, making the assembly of the first support plate 610, the second support plate 620, and the second flexible circuit board 640 easier and more cost-effective. Furthermore, since both the first support plate 610 and the second support plate 620 are insulated from the second flexible circuit board 640, the electrical interaction of the second flexible circuit board 640 is less susceptible to the influence of the first support plate 610 and the second support plate 620.

[0151] like Figure 7 As shown, in some possible embodiments, the third plug end 641 is bonded to the third side surface 612 by a third adhesive layer 653, and the fourth plug end 642 is bonded to the fourth side surface 622 by a fourth adhesive layer 654. Both the third adhesive layer 653 and the fourth adhesive layer 654 are insulating layers.

[0152] This facilitates the insulation and fixed connection between the third plug-in end 641 and the third side 612, and between the fourth plug-in end 642 and the fourth side 622. The assembly difficulty of the first support plate 610 and the second support plate 620 and the second flexible circuit board 640 is relatively low, and the flexible connection device 600 is easier to form and has a lower cost.

[0153] In some examples, the third adhesive layer 653 and the fourth adhesive layer 654 can both be structural layers formed by hot pressing of a prepreg. The third insertion end 641 and the first support plate 610, and the fourth insertion end 642 and the second support plate 620 can be fixedly connected by hot pressing.

[0154] In other examples, the third adhesive layer 653 and the fourth adhesive layer 654 can be adhesive backing layers, that is, the third insertion end 641 and the third side 612, and the fourth insertion end 642 and the fourth side 622 can be bonded by adhesive backing.

[0155] In some possible implementations, the first connecting portion 633 and the second connecting portion 643 are insulated from each other. In this case, no electrical connection is required between the first flexible circuit board 630 and the second flexible circuit board 640, making the assembly of the first flexible circuit board 630 and the second flexible circuit board 640 easier and the flexible connecting device 600 easier to form and less expensive. Furthermore, since the first flexible circuit board 630 and the second flexible circuit board 640 are insulated from each other, they are less likely to interfere with each other.

[0156] In some possible implementations, the first connecting portion 633 and the second connecting portion 643 are bonded together by a fifth adhesive layer 655, which is an insulating layer.

[0157] This facilitates the insulation and fixed connection between the first connecting part 633 and the second connecting part 643, reduces the assembly difficulty of the first connecting part 633 and the second connecting part 643, and makes the flexible connecting device 600 easier to form and lower in cost.

[0158] In some examples, the fifth adhesive layer 655 can be a structural layer formed by hot pressing a prepreg, and the first connecting part 633 and the second connecting part 643 can be fixedly connected by hot pressing.

[0159] In other examples, the fifth adhesive layer 655 can be an adhesive backing layer, that is, the first connecting part 633 and the second connecting part 643 can be bonded together with adhesive backing.

[0160] In some examples where the flexible connection device 600 includes a first connector housing 660, the first connector housing 660 is sleeved on the outside of the first support plate 610, the first plug-in end 631, and the third plug-in end 641, and is fixedly connected to the first support plate 610, the first plug-in end 631, and the third plug-in end 641. The first connector housing 660, the first support plate 610, the first plug-in end 631, and the third plug-in end 641 are used to form a first connector structure. Exemplarily, the first support plate 610, the first plug-in end 631, and the third plug-in end 641 are located between the first half-shell and the second half-shell, and the first support plate 610, the first plug-in end 631, and the third plug-in end 641 can be pressed and fixed by the first half-shell and the second half-shell.

[0161] In some examples where the flexible connection device 600 includes a second connector housing 670, the second connector housing 670 is sleeved on the outside of the second support plate 620, the second insertion end 632, and the fourth insertion end 642, and is fixedly connected to the second support plate 620, the second insertion end 632, and the fourth insertion end 642. The second connector housing 670, the second support plate 620, the second insertion end 632, and the fourth insertion end 642 are used to form a second connector structure. Exemplarily, the second support plate 620, the second insertion end 632, and the fourth insertion end 642 are located between the third half-shell and the fourth half-shell, and the second support plate 620, the second insertion end 632, and the fourth insertion end 642 can be pressed and fixed by the third half-shell and the fourth half-shell.

[0162] In some examples where the first support plate 610 has a first snap-fit ​​structure 613, the third plug-in end 641 has a protruding structure or a recessed structure opposite to the first snap-fit ​​structure 613.

[0163] For example, the first snap-fit ​​structure 613 is a slot, and the third insertion end 641 has a notch structure at the position opposite to the first snap-fit ​​structure 613.

[0164] For example, the first snap-fit ​​structure 613 is a snap-fit ​​edge, and the third plug-in end 641 may cover the part of the third side 612 located in the first snap-fit ​​structure 613, or it may not cover the part of the third side 612 located in the first snap-fit ​​structure 613.

[0165] In some examples where the second support plate 620 has a second snap-fit ​​structure 623, the fourth plug-in end 642 has a protruding structure or a recessed structure opposite to the second snap-fit ​​structure 623.

[0166] For example, the second snap-fit ​​structure 623 is a slot, and the fourth insertion end 642 has a notch structure at the position opposite to the second snap-fit ​​structure 623.

[0167] For example, the second snap-fit ​​structure 623 is a snap-fit ​​edge, and the fourth plug-in end 642 may cover the part of the fourth side 622 located in the second snap-fit ​​structure 623, or it may not cover the part of the fourth side 622 located in the second snap-fit ​​structure 623.

[0168] Figure 8 This is a schematic diagram of yet another electronic device provided in an embodiment of this application.

[0169] like Figure 8As shown, in some examples where the first component 200 has a first connector 510 and the second component 300 has a second connector 520, there is a gap between the third component 400 and the base plate 121, and the first flexible circuit board 630 passes through the gap between the third component 400 and the base plate 121. Specifically, the first connecting portion 633 passes through the gap between the second circuit board 410 and the base plate 121.

[0170] This allows for wiring to be routed using the gap between the third component 400 and the base plate 121, improving the space utilization of the installation area. Additionally, it helps shorten the transmission path between the first connector 510 and the second connector 520, thereby reducing transmission loss and improving their interaction performance. Furthermore, the third component 400 can partially shield the flexible connection device 600, preventing it from rubbing against other components and maintaining a neater structure within the installation space.

[0171] In some examples where the flexible connection device 600 includes a second flexible circuit board 640, the second flexible circuit board 640 also passes through the gap between the third component 400 and the base plate 121. Specifically, the second connecting portion 643 passes through the gap between the second circuit board 410 and the base plate 121.

[0172] For example, the third component 400 can be fixedly connected to the base plate 121 via a support structure to form a gap between the third component 400 and the base plate 121. Specifically, the second circuit board 410 can be fixedly connected to the base plate 121 via a support structure to form a gap between the second circuit board 410 and the base plate 121.

[0173] The first flexible circuit board 630 may include one or more conductive layers and one or more insulating layers. For example, the first flexible circuit board 630 may include one, two, three, or four conductive layers. When the first flexible circuit board 630 includes multiple conductive layers, an insulating layer is provided between two adjacent conductive layers.

[0174] Figure 9 This is a schematic diagram of a first flexible circuit board provided in an embodiment of this application.

[0175] like Figure 9As shown, exemplarily, the first flexible circuit board 630 may include a first conductive layer L1, a second conductive layer L3, a third conductive layer L5, a first insulating layer L2, and a second insulating layer L4.
