[0039] Embodiment 1

[0040] See first Figures 1 to 6 As shown, the flexible connection device provided by the utility model includes an FPC component 1 and a connector 2; the above-mentioned FPC component 1 includes a first FPC 11, a second FPC 12 and a multi-layer circuit layer 13; the above-mentioned multi-layer circuit layer 13 is respectively configured on the above-mentioned first FPC 11 and the above-mentioned second FPC 12; the two ends of the above-mentioned first FPC 11 are respectively configured with connection areas 14, and the above-mentioned connection areas 14 include a connection terminal portion 141 and a first welding portion 142; the two ends of the above-mentioned second FPC 12 are respectively configured with second welding portions 15, and the above-mentioned first welding portion 142 is correspondingly welded with the above-mentioned second welding portion 15 to make the circuit layer 13 of the above-mentioned first FPC 11 communicate with the circuit layer 13 of the above-mentioned second FPC 12; the above-mentioned connector 2 is used to connect the above-mentioned connection terminal portion 141 with an external communication device.

[0041] Specifically, the multi-layer circuit layer 13 is respectively configured on the first FPC11 and the second FPC12, so that the original multi-layer circuit layer 13 is distributed to more FPC boards, the actual copper layer thickness of each circuit layer 13 is increased, and the heat release efficiency of each circuit layer 13 when running at the maximum current is improved. The ends of the first FPC11 and the second FPC12 are connected by the first welding portion 142 and the second welding portion 15 to connect the circuit layers 13 of the first FPC11 and the second FPC12. Finally, the information transmitted by the FPC assembly 1 is connected to the external communication device through the connector 2 at the end of the first FPC11, so that data information can be transmitted without replacing the connector 2, thereby meeting the installation requirements in a narrow space.

[0042] Among them, a four-layer circuit layer 13 is taken as an example. The original four-layer circuit layer 13 is distributed in one FPC, and now the four circuit layers 13 are distributed in the first FPC11 and the second FPC12, so that the four-layer circuit layer 13 is configured on multiple FPC boards. Under the premise that the thickness of a single FPC board remains unchanged, the thickness of each circuit layer 13 in the four-layer circuit layer 13 is increased by at least one time, and the thickness of the corresponding copper layer is also increased by at least one time, so that the FPC component 1 can dissipate the heat generated as quickly as possible when transmitting a large current; and the first FPC11 and the second FPC12 are connected through the first welding portion 142 and the second welding portion 15, and the end of the first FPC11 is configured with a connector 2 connection, and the end connector 2 connects the two devices to be communicated, so as to transmit information in a narrow installation space without changing the size of the connector 2, thereby meeting various usage requirements.

[0043] Among them, the usage scenarios of the flexible connection device provided by the utility model are mostly narrow spaces. The flexible connection device can not only match the direction of the actual installation space, but also can easily adjust the conveying direction, and has good performance.

[0044] Exemplarily, the multi-layer circuit layer 13 includes a high-current circuit layer 131 and a low-current circuit layer 132 ; the high-current circuit layer 131 is configured on the first FPC 11 , and the low-current circuit layer 132 is configured on the second FPC 12 .

[0045] Specifically, by distributing the high current circuit layer 131 in the multi-layer circuit layer 13 on the first FPC 11 and configuring the low current circuit layer 132 on the second FPC 12, the low current circuit layer 132 and the high current circuit layer 13 are separately arranged to avoid the problem of mutual interference of the generated heat.

[0046] Among them, the high-current circuit layer 131 and the low-current circuit layer 132 are classified according to actual conditions, mainly by comparing the maximum current amounts of multiple circuit layers 13, classifying the larger maximum current amount in the circuit layer 13 as the high-current circuit layer 131, and classifying the smaller maximum current amount in the circuit layer 13 as the low-current circuit layer 132.

[0047] Preferably, a circuit layer 13 having the largest maximum current is selected from the multi-layer circuit layers 13, and the current layer is configured on the first FPC 11 or the second FPC 12, and all remaining circuit layers 13 are configured on the second FPC 12 or the first FPC 11. As long as it can be ensured that the heat dissipated by the FPC can be well dissipated when the multi-layer circuit layers 13 are transmitting the maximum current, the FPC assembly 1 can be prevented from being in a high-temperature state for a long time.

[0048] Exemplarily, the first FPC 11 and / or the second FPC 12 includes a bending area 16 and a straight area 17 ; the bending area 16 is located at both sides of the straight area 17 .

[0049] Specifically, by setting the bending area 16 on both sides of the straight area 17, that is, the bending area 16 is close to the communication device, it is ensured that during the information data transmission process of the FPC component 1, the bending area 16 can better adapt to the narrow installation space, so that the data information can be more stably connected to the communication device through the connector 2.

[0050] Among them, since the two ends of the FPC component 1 are connected to the communication equipment, that is, the two ends are in a relatively narrow installation space, the bending area 16 is set at both ends of the entire FPC component 1 to better match various installation environments.

[0051] It is worth mentioning that the cross-sectional width of the straight area 17 is smaller than the cross-sectional width of the bending area 16, so as to ensure that during the data transmission process, the overall flexible connection device occupies a smaller installation area, is easier to install, and is more suitable for operations such as threading, thereby improving performance.

[0052] Exemplarily, the corners of the bending area 16 are rounded.

[0053] Specifically, by rounding the corners of the bending area 16 , the smoothness of the corners of the bending area 16 is increased, the bending area 16 is prevented from being easily bent, and the service life of the FPC assembly 1 is increased.

[0054] The direction of the rounded corners of the bending area 16 is toward the bending direction of the bending area 16, which is conducive to ensuring the flexibility of the bending area 16 in the bending direction and avoiding bending. It is worth mentioning that the inner and outer sides of the corners of the bending area 16 are rounded to ensure overall flexibility.

[0055] Exemplarily, the first FPC 11 and the second FPC 12 have the same size.

[0056] Specifically, the first FPC 11 and the second FPC 12 have the same size, which means that the first FPC 11 and the second FPC 12 are of the same size, that is, the length, width and height are the same, which is conducive to ensuring the convenience of operation when the first FPC 11 and the second FPC 12 are welded.

[0057] Preferably, the first FPC 11 and the second FPC 12 are the same FPC board.

[0058] Exemplarily, the number of the second FPC 12 is at least one.

[0059] Specifically, by selecting one second FPC 12, that is, configuring multiple circuit layers 13 on two FPCs; when selecting two second FPCs 12, that is, configuring multiple circuit layers 13 on three FPCs, the copper layer of each circuit layer 13 in the multi-layer circuit layer 13 is thicker, which is conducive to heat dissipation. It is worth mentioning that the two second FPCs 12 are respectively welded to the front and back of the first FPC 11, which is conducive to improving welding efficiency.

[0060] For example, when there are six circuit layers 13 and the number of the second FPC 12 is one, the six circuit layers 13 are respectively located on two FPC bodies. According to the equal distribution consideration, each FPC board is configured with three circuit layers 13, while the control FPC board is configured with six circuit layers 13. After the improvement, the thickness of each circuit layer 13 becomes larger, that is, the heat dissipation effect of the FPC board will also be improved.

[0061] For example, when the circuit layer 13 is six layers, when the number of the second FPC 12 is two; the six circuit layers 13 are respectively located on three FPC bodies, and according to the equal distribution consideration, that is, each FPC board is configured with two circuit layers 13, and the control FPC board is configured with six circuit layers 13. After the improvement, the thickness of each circuit layer 13 becomes larger, that is, the heat dissipation effect of the FPC board will also be improved.

[0062] Among them, it is preferred to place the circuit layer 13 that generates more heat separately on an FPC board, which is beneficial to ensure that the overall FPC assembly 1 can have a better heat dissipation effect.

[0063] Exemplarily, both end surfaces of the connection region 14 are provided with connection terminal portions 141 .

[0064] Specifically, by configuring the connection terminal portion 141 on both the front and rear surfaces of the connection area 14, the connection terminal portion 141 can avoid the problem of loose insertion due to the warping of the connection terminal portion 141 when connected to the connector 2. That is, when both end surfaces of the connection area 14 are configured with the connection terminal portion 141, when any end surface is warped, the other end surface can still be connected to the connector 2, thereby improving the stability and reliability of the product.

[0065] Preferably, the connection terminal portion 141 and the connector 2 are plug-connected, so that the connection terminal portion 141 can be quickly integrated with the connector 2 .

[0066] The connector 2 corresponding to the connection terminal portion 141 is a double-sided connector 2 to match the connection terminal portion 141 .

[0067] Among them, both end surfaces of the connection area 14 are configured with connection terminal parts 141, and the connection terminal parts 141 on the two end surfaces are completely consistent and can transmit the same data information; when the connection terminal part 141 on one end surface is connected to the connector 2, the connection terminal part 141 on the other end surface is in an open circuit and non-working state, and vice versa.

[0068] Exemplarily, the first welding portion 142 includes a first welding pad, the second welding portion 15 includes a second welding pad, and the second welding pad is provided with a welding hole.

[0069] Specifically, a first soldering pad is set on the first soldering portion 142, and a soldering hole is configured on the second soldering pad set on the second soldering portion 15. The first FPC11 and the second FPC12 are superimposed and laid flat so that the first soldering portion 142 and the second soldering portion 15 overlap, and the first soldering pad and the second soldering pad are connected by soldering the corresponding soldering holes on the second soldering pad.

[0070] There are multiple welding holes, and the multiple welding holes are evenly arranged on the second pad, which is conducive to achieving stable connection between the first FPC 11 and the second FPC 12.

[0071] Among them, the welding hole is preferably a long strip welding hole, so that welding is more convenient and the operation is simple and convenient.

[0072] Exemplarily, a fixing belt 3 is further included; the fixing belt 3 can be wrapped around the first FPC 11 and the second FPC 12 .

[0073] Specifically, by binding the first FPC 11 and the second FPC 12 with the fixing tape 3, the problem that the FPC assembly 1 occupies a large space during the information transmission process is avoided.

[0074] The fixing belt 3 may include a fixing buckle to achieve locking after binding the first FPC 11 and the second FPC 12, thereby improving the fixing efficiency.

[0075] There are preferably two fixing belts 3, which are respectively located on both sides to stably fix the first FPC 11 and the second FPC 12. Of course, the number of fixing belts 3 can also be selected, with one fixing belt 3 wrapped around the middle of the first FPC 11 and the second FPC 12.

[0076] The fixing belt 3 is preferably made of rubber material, which has good elasticity and avoids the problem of wear on the FPC.

[0077] The utility model also provides a surgical robot, comprising the above-mentioned flexible connecting device.

[0078] Specifically, an instrument is installed at the end of the robotic arm on the patient side of the surgical robot. When the robotic arm on the patient side transmits the control signal to the instrument at the end, the communication transmission space is very narrow. When a flexible connection device is selected for control signal transmission, the overall device has good flexibility and can also quickly dissipate heat when transmitting signals with large current among multiple control signals, thereby ensuring the safety performance of the surgical robot.

[0079] Embodiment 2

[0080] like Figure 7-8 As shown, the difference between this embodiment and the first embodiment is that the multiple circuit layers 13 are evenly arranged on the first FPC 11 and the second FPC 12 .

[0081] Specifically, by evenly disposing the multi-layer circuit layer 13 on the first FPC 11 and the second FPC 12, the FPC assembly 1 can generate relatively balanced heat when transmitting signals of the multi-layer circuit layer 13, thereby ensuring that the heat generated on each FPC board is relatively small.

[0082] The multi-layer circuit layer 13 is evenly arranged on the first FPC 11 and the second FPC 12. It is preferred to mix the higher current circuit layer 131 and the lower current circuit layer 132 in the multi-layer circuit layer 13 and evenly divide them to achieve a more balanced current on each FPC board. For example, both the high current circuit layer 131 and the low current circuit layer 132 are distributed on the first FPC 11. It is preferred to arrange the high current circuit layer 131 on the lower end surface of the first FPC 11, which is beneficial to the heat dissipation of the high current circuit layer 131; on the second FPC 12, both the high current circuit layer 131 and the low current circuit layer 132 are distributed. It is preferred to arrange the high current circuit layer 131 on the upper end surface of the second FPC 12, which is beneficial to the heat dissipation of the high current circuit layer 131.

[0083] In summary, the flexible connection device provided by the utility model configures the multi-layer circuit layer 13 on the first FPC11 and the second FPC12 respectively, so as to distribute the original multi-layer circuit layer 13 to more FPC boards, increase the actual copper layer thickness of each circuit layer 13, and improve the heat release efficiency of each circuit layer 13 when transmitting large current. The ends of the first FPC11 and the second FPC12 are connected by the first welding portion 142 and the second welding portion 15 to connect the circuit layers 13 of the first FPC11 and the second FPC12. Finally, the information transmitted by the FPC component 1 is connected to the external communication device through the connector 2, so as to transmit data information without replacing the connector 2, thereby meeting the installation requirements in a narrow space.
