Especially for ultrasound equipment or monitoring equipment, the host of the ultrasound equipment or monitoring equipment and the touch screen are usually connected by three connecting cables, namely the display cable, the signal cable and the power cable. In clinical use, there are the following inconveniences between the host and the touch screen: the three connecting cables need to be plugged and unplugged many times, which is inconvenient and time-consuming; and the three connecting cables are easily tangled together and difficult to separate, resulting in a poor user experience.

[0038] The embodiments of the utility model provide a cable assembly, a display screen and a medical device, thereby solving the problems of inconvenient plugging and unplugging of connecting cables between the existing host and the touch screen and cable entanglement and knotting. The three connectors on the host end are replaced by an aviation connector, and the three connectors on the display end are replaced by an adapter plate, so as to achieve rapid interoperability between the display screen and the host.

[0039] The embodiment of the utility model is to solve the above-mentioned problems of inconvenient plugging and unplugging and cable entanglement and knotting, and its technical solution is as follows:

[0040] The specific solution is to integrate the three interfaces of the display cable, signal cable and power cable through an aviation connector, so that three different functions can be realized while convenient and quick plugging and unplugging. Compared with the original three plug-in interfaces, it is improved to the current one plug-in interface, which takes 1 / 3 of the original time, greatly saving time; then design an adapter board, and the display cable, signal cable and power cable are connected to the board on the display screen through the adapter board. The adapter board is built into the display screen, so that the cable assembly has only one aviation connector plug. Therefore, you only need to plug and unplug the aviation connector and the host. In clinical use, there is only one plug-in and unplug, which saves 2 / 3 of the time and is more conducive to clinician operation. The operation is simple, quick and convenient, and the user experience is good.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Reference Figure 1-Figure 9 , Figure 1A schematic diagram of a cable assembly 100 provided for an embodiment of the utility model, the cable assembly 100 includes: a connector 1, a display core wire 2, a signal core wire 3, a power core wire 4, an outer sheath 5 and an adapter plate 6, the display core wire 2, the signal core wire 3 and the power core wire 4 are twisted together to form a fused cable, the fused cable is wrapped by the outer sheath 5, one end of the fused cable is connected to the connector 1, and the other end of the fused cable is connected to the adapter plate 6.

[0043] Reference Figure 2Specifically, the connector 1 is an aviation connector with a quick plug-in and self-locking structure to improve the reliability of the connection. The display core line 2 can be a line for transmitting video signals and control signals that can realize the display function, such as HDMI (High Definition Multimedia Interface), VGA (Video Graphics Array), DVI (Digital Visual Interface), etc. Specifically, the HDMI line can adopt a standard HDMI 19-core line. The signal core line 3 can be a line that can realize data transmission, such as USB (Universal Serial Bus), Lightning (Apple line), Type-C (Android line), micro USB, etc. Specifically, the USB line can adopt a standard USB2.0 four-core wire. The power cord 4 can be a line that can realize the power supply function, such as a DC power cord (direct current), an AC power cord (Alternating Current), etc. Specifically, the DC power cord can adopt a DC four-core wire. The display core wire 2, the signal core wire 3 and the power core wire 4 are twisted together to obtain a fused cable, which is wrapped by an outer sheath 5. From the cross section of the cable assembly 100, the core wires of the cable assembly 100 include four parts: A, B, C, and D. Part A, as the differential signal part of HDMI 0 / 1 / 2 and CLK clock, uses 30AWG (American wire gauge) silver-plated twisted pair plus bare ground wire wrapped with aluminum foil Mylar; Part B, as USB2.0 D+ / D-, uses 28AWG silver-plated twisted pair wire wrapped with aluminum foil Mylar; Among the seven core wires in part C, C1-C3 are used as ground wires, and C4-C7 are used as a pair of IIC (Inter-Integrated Circuit) and HDMI HPD (Hot Plug Detect), Vcc5V; Part D, as a DC power supply, uses two-core 24AWG*2 tinned copper wires and USB 5V power supply uses 24AWG*2 tinned copper wires. The adapter board 6 is connected to the board 8 in the display screen 200, so that the adapter board 6 is built into the display screen 200, so the end of the cable assembly 100 connected to the display screen 200 does not need to be plugged in and out, leaving only the end of the cable assembly 100 connected to the host 300, that is, the aviation connector needs to be plugged in and out. Then, when used clinically, the doctor only needs to plug the aviation connector into the host 300 to achieve a quick inter-matching connection between the display screen 200 and the host 300.

[0044] By implementing this embodiment, the connector 1 is used to integrate the three interfaces of the display line, signal line and power line, and three different functions are realized at the same time, which is convenient and quick to plug and unplug. Compared with the original three plug-in interfaces, the time is 1 / 3 of the original, which greatly saves time; and compared with the high probability of poor connection of the three plug-in interfaces at the same time, the aviation plug-in interface of this embodiment is locked, and the connection reliability is greatly improved; the adapter board 6 and the board 8 of the display screen 200 are also used for connection, which is simple to process, low in cost and high in assembly efficiency. Therefore, this embodiment integrates three different functional connection lines into one cable, solves the problems of cumbersome plug-in and cable knotting, and is convenient and quick to plug and unplug. The cable assembly 100 is lighter and simpler, convenient for daily maintenance and easier to store.

[0045] Continue to refer to Figure 2 In one embodiment, the outer sheath 5 includes a double-layer aluminum foil Mylar (not shown in the figure) and a silver-plated braided layer 51.

Specifically, the aluminum foil Mylar is made of metal aluminum foil as a base material, and is bonded with a polyester tape (generally PET (Polyethylene terephthalate, polyester resin) PP (polypropylene, polypropylene), etc.) after adhesive bonding. This embodiment uses a double-layer aluminum foil Mylar to wrap the core wire to improve the interference shielding performance. The double-layer aluminum foil Mylar is located on the outer layer of the core wire, and the silver-plated braided layer 51 is located on the outer layer of the double-layer aluminum foil Mylar. One end of the silver-plated braided layer 51 is connected to the aviation connector, and the other end is connected to one end of the conductive member 7. The silver-plated braided layer 51 further improves the ability to shield electromagnetic interference on the one hand, and can respond to leakage in a timely manner on the other hand.

[0046] In this embodiment, a silicone film layer is also coated on the outer side of the silver-plated braided layer 51. Specifically, after the core wires are twisted as a whole, the outer layer adopts a double-layer shielded aluminum foil Mylar and a silver-plated braided layer 51, and the outer sheath 5 adopts a silicone coating process. The overall wire is soft and has a certain elasticity. The coating process ensures that the wire is dust-free, anti-static, easy to clean, and has excellent smoothness and durability.

[0047] In one embodiment, the cable assembly 100 further includes an insulating member (not shown in the figure), and a pad welded to the other end of the fused cable is provided on the adapter plate 6, and the insulating member covers the pad. Specifically, the pad is provided at the edge of the adapter plate 6, and the other end of the fused cable is welded to the pad at the edge of the adapter plate 6. In order to insulate the pad, the present embodiment is provided with an insulating member, and the insulating member covers the pad, covering the area where the other end of the fused cable is welded to the pad, thereby insulating the pad, protecting the pad, and preventing the solder joint from being disturbed.

In this embodiment, the outer jacket 5 is connected to the exposed copper area by providing a conductive member 7, so that the wire and the adapter board 6 share the same ground, which plays a role in shielding electromagnetic interference. Specifically, the conductive member 7 is connected to the silver-plated braided layer 51 of the outer jacket 5, the insulating member covers the pad, the conductive member 7 covers the outer layer of the insulating member, the portion between the two ends of the conductive member 7 covers the insulating member, and the conductive member 7 shares the ground between the adapter board 6 and the wire, thereby achieving shielding at the connection between the wire and the adapter board 6.

[0049] Reference Figure 4-Figure 6 In one embodiment, the adapter board 6 includes a first surface and a second surface opposite to each other, and the copper-exposed area includes a first copper-exposed area 61 provided on the first surface and a second copper-exposed area 62 provided on the second surface, wherein the first copper-exposed area 61 is connected to the conductive member 7, and the second copper-exposed area 62 is used to connect to the ground terminal on the board 8. In order to further improve the electromagnetic shielding performance, specifically, the first copper-exposed area 61 and the second copper-exposed area 62 are respectively provided on the two opposite first surfaces and the second surface of the adapter board 6, and the first copper-exposed area 61 and the second copper-exposed area 62 are both ground terminals of the adapter board 6. The first copper-exposed area 61 is connected to the outer jacket 5 through the conductive member 7, so that the wire and the adapter board 6 are in common ground, and shielding is achieved at the connection between the wire and the adapter board 6. The second copper-exposed area 62 is used to connect to the ground terminal on the board 8 of the display screen 200, so that the adapter board 6 and the board 8 are in common ground, and shielding is achieved at the adapter board 6 and the board 8. Specifically, a third copper-exposed area (not shown) is provided on the board 8 of the display screen 200, and the second copper-exposed area 62 is electrically connected to the third copper-exposed area through a conductive docking piece 9, so that the adapter board 6 and the board 8 are grounded together, thereby improving the electromagnetic shielding performance.

[0050] Continue to refer to Figure 4-Figure 6In one embodiment, the pad includes a first pad 63 provided on the first surface and a second pad 64 provided on the second surface, the insulating member includes a first insulating sheet and a second insulating sheet, the first insulating sheet is attached to the first pad 63, and the second insulating sheet is attached to the second pad 64; the conductive member 7 includes a first conductive cloth 71 and a second conductive cloth 72, the first conductive cloth 71 covers the side of the first insulating sheet facing away from the first pad 63, one end of the first conductive cloth 71 overlaps the outer jacket 5, and the other end of the first conductive cloth 71 overlaps the first copper exposed area 61; the second conductive cloth 72 covers the side of the second insulating sheet facing away from the second pad 64, one end of the second conductive cloth 72 overlaps the outer jacket 5, and the other end of the second conductive cloth 72 overlaps the second copper exposed area 62. Specifically, the fusion cable and the adapter board 6 of this embodiment are double-sided welded, and the first pad 63 and the second pad 64 are respectively provided at the edges of the first surface and the second surface, and the core wire is welded to the first pad 63 and the second pad 64 to ensure the reliability of the connection. In this way, the pads on both sides are covered with insulating parts. The insulating parts of this embodiment are in the form of insulating sheets pasted on the pads to cover the pads. In practical applications, high-temperature adhesive tape can be used for pasting. Specifically, the insulating parts include a first insulating sheet and a second insulating sheet. The first insulating sheet and the second insulating sheet are respectively pasted on the first pad 63 and the second pad 64 at the edge to insulate the first pad 63 and the second pad 64 respectively to protect the pads. In addition, in order to ensure the integrity of the shielding, two conductive parts 7 are required to cover the outer layers of the two insulating sheets. The conductive parts 7 of this embodiment are covered in the form of conductive cloth. Specifically, the conductive part 7 includes a first conductive cloth 71 and a second conductive cloth 72. The first conductive cloth 71 and the second conductive cloth 72 are roughly triangular in shape. The top ends of the two triangles overlap with the silver-plated braided layer 51 of the outer jacket 5, and the two triangular sides opposite to the top ends overlap with the first copper-exposed area 61 and the second copper-exposed area 62 on the adapter board 6 respectively. The entire triangular area of ​​the first conductive cloth 71 covers the first insulating sheet. Similarly, the entire triangular area of ​​the second conductive cloth 72 covers the second insulating sheet. The two conductive cloths realize the common ground of the wire and the adapter board 6, thereby ensuring the integrity of the shielding at the wire and the adapter board 6.

[0051] In this embodiment, a through conductive connection hole (not shown in the figure) is provided between the first copper exposed area 61 and the second copper exposed area 62, and the conductive connection hole is used to be fixedly connected to the grounding terminal of the board 8. Specifically, the conductive connection hole passes through the first surface and the second surface of the adapter board 6, and respectively forms an electrical connection with the first copper exposed area 61 on the first surface and the second copper exposed area 62 on the second surface, thereby making the two copper exposed areas share a common ground. The conductive connection hole short-circuits the two copper exposed areas on the one hand, and is used to fasten with the board 8 on the other hand to ensure the reliability of the connection.

[0052] Reference Figure 4 and Figure 5 In this embodiment, the first copper-exposed area 61 and the second copper-exposed area 62 each include a long side and two short sides, and the two short sides are vertically connected to the two ends of the long side; the two ends of the two short sides away from the long side are connected to the other end of the conductive member 7. Specifically, the first copper-exposed area 61 and the second copper-exposed area 62 of this embodiment are both strip-shaped copper-exposed areas, and the specific shape is a rectangle with one long side missing, and the position of the missing long side is to avoid the empty pad. The other end of the conductive cloth can be overlapped with the two short sides to achieve the conductive connection with the copper-exposed area. Specifically, the other end of the first conductive cloth 71 overlaps with the two short sides of the first copper-exposed area 61, and the other end of the second conductive cloth 72 overlaps with the two short sides of the second copper-exposed area 62. Designing the copper-exposed area into a rectangular shape is, on the one hand, to avoid the electronic components in the middle, and on the other hand, to increase the conductive contact area with the conductive docking member 9 and improve the reliability of the connection. Of course, it can be understood that in other embodiments, the first copper-exposed area 61 and the second copper-exposed area 62 can also be other shapes, such as rings, arcs, etc., which are specifically set according to actual needs.

[0053] Furthermore, there are four conductive connection holes, two of which are arranged at the vertical connection between the two short sides and the long sides, and the other two are arranged at the two ends of the two short sides away from the long sides. Specifically, two conductive connection holes are arranged at the right angles of the rectangle, and two conductive connection holes are arranged at the ends of the two short sides of the rectangle. The four conductive connection holes are used to connect the grounding terminals of the adapter board 6 and the board card 8 to ensure the reliability and stability of the common ground.

[0054] Reference Figure 7 and Figure 8 In this embodiment, the second copper-exposed area 62 is provided with a pin header 65 for connecting with the board 8. Specifically, the second copper-exposed area 62 is used to connect with the third copper-exposed area on the board 8. The second copper-exposed area 62 faces the board 8, so the pin header 65 is set in the second copper-exposed area 62, and the adapter board 6 is electrically connected to the board 8 through the pin header 65 to complete the signal transmission. Through this connection method between the adapter board 6 and the display screen 200 board 8, the display screen 200 can be made thinner, the overall appearance is more beautiful, and it is easy to carry, which will improve the user experience and visual sense of the product.

[0055] In one embodiment, the connector 1 includes a wire clamp (not shown in the figure), one end of the fused cable is coated with copper foil (not shown in the figure), and the wire clamp is sleeved on the copper foil and has an interference fit with the copper foil. Specifically, the wire clamp is a three-petal wire clamp, which is in the shape of a sleeve and has three slits on one side, so it is a three-petal wire clamp. Specifically, the silver-plated braided layer 51 of the outer jacket 5 is folded back and wrapped with copper foil, and the wire clamp is sleeved on the copper foil and has an interference fit with the copper foil, which ensures the reliability of contact and the integrity of the 360° annular shielding, thereby realizing the shielding between the connector 1 and the wire.

[0056] In addition, when the connector 1 is plugged into or unplugged from the host 300 , the base of the connector 1 is in contact and communication with the housing of the host 300 , thereby sharing a common ground.

[0057] Through the above embodiments, shielding is achieved at the connection between the connector 1 and the wire, shielding is achieved between the wire and the adapter board 6, and shielding is achieved between the adapter board 6 and the board 8. A complete shielding environment is provided in the entire transmission link from the host 300 to the display screen 200, which ensures reliable and interference-free signal transmission and prevents radiation leakage.

[0058] In one embodiment, the connector 1 is provided with a power pin, a return ground pin and a signal pin, wherein the power pin and the return ground pin are long pins (not shown in the figure), and the signal pin is a short pin (not shown in the figure). In order to achieve hot plugging, this embodiment separates the pins of the connector 1, one part is a long pin, and the other part is a short pin, and hot plugging is achieved by successively conducting the long pin and the short pin. Hot plugging is live plugging, which means that without turning off the system power, the connector 1 is inserted or unplugged from the system without affecting the normal operation of the system, that is, when the connector 1 is powered on, the insertion or unplugging does not affect the signal, does not affect the normal function, and does not need to be turned on and off to restart, thereby improving the reliability of the system, the ability to recover in time, etc. Specifically, the connector 1 is provided with 30 pins (i.e., pins), wherein 8 pins are extended as power and return ground, wherein 4 pins are used as power and 4 pins are used as return ground. The remaining 22 pins are for signals, and the two are separated. In this long and short contact method, during the insertion process: the power supply and return ground 8 pins are connected first, and the signal pin is not in contact at the moment of connection. When the power supply and return ground pin are fully in contact and the power supply is stable, the signal pin will be in contact, thereby ensuring the stability of the signal. During the removal process: the short pin of the signal pin is disconnected first, and then the long pin power supply and return ground pin are disconnected. All communications are terminated before the module is powered off, thereby ensuring that the signal is not lost. In this way, through the long and short pin design of this embodiment, during the insertion process, when the long pin is inserted, the short pin is not in contact, and the signal will not be affected by transient current or sudden voltage generated during the contact process. Compared with the traditional three-stage pin structure, the longest pin of the three sections is the ground pin, followed by the power supply and signal pins. When connected to the host, the ground pin is connected first, the purpose of which is to share the ground with the host, eliminate the potential difference between the boards of the circuit board, and reduce the impact on the circuit. In this embodiment, when the aviation connector is inserted, the shell of the aviation connector contacts the host, which can achieve common ground with the host, and there is no need to design the ground pin to be the longest. The purpose of designing the power pin and return ground as long pins in this embodiment is that the DC power supply and its independent power return ground, the long pin is fully in contact so that the voltage and current remain stable. Therefore, when the short pin is about to be inserted, the long pin is already in full contact, the voltage and current are stable, and there will be no interference to the signal; during the process of pulling out the pin, the signal short pin is disconnected first, at this time the power long pin is fully in contact, and all communications are terminated before the system is powered off, the normal signal is disconnected, and the signal is not lost.
