[0003] Currently, most medical device mainframes on the market use solder cup-type aviation connector sockets or 90° angle aviation connector sockets for external connections. Please refer to [link / reference]. Figure 1 The solder cup type aviation connector socket connects to the host device by soldering the corresponding cable to the solder cup 01 at its tail end. Please refer to [link / reference]. Figure 2 The 90° bend aviation connector socket connects to the mainboard via its 90° bend pin 02, which is soldered to the mainboard.
[0004] However, the manufacturing and assembly process of solder cup-type aviation connector sockets is complex and has a high defect rate. During the assembly of 90° bend aviation connector sockets, the pins are prone to deformation, leading to high-speed signal quality problems such as crosstalk. In addition, the exposed pins are also a high-risk area for electromagnetic radiation.

[0032] This application discloses a connector assembly and a device host to facilitate assembly and improve signal quality.
[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0034] The connector assembly provided in this application is used for electrical connection between two devices to transmit signals and / or current. It is applicable to, but not limited to, connections between a touchscreen and a device host, such as connections between a touchscreen and a medical device host. Exemplarily, the connector assembly is located on the device host, and a corresponding connection end is provided on the touchscreen. For example, the connector assembly serves as the female connection end, and the touchscreen has a male connection end. When connecting the touchscreen to the device host, the male connection end mates with the female connection end. The structure of the connector assembly is described in the following embodiments.
[0035] In some embodiments, please refer to 3- Figure 5 The connector assembly provided in this application includes an adapter circuit board 1, a housing 2, and pins 3. The adapter circuit board 1 has a circuit board body 13 and a plug-in portion 14, with gold fingers 11 on the plug-in portion 14. The number of gold fingers 11 can be set as needed and is not specifically limited here. It is understood that the circuit board body 13 and the plug-in portion 14 are two parts of the adapter circuit board 1. For example, the plug-in portion 14 is used to plug into the motherboard of the device host. The adapter circuit board 1 and the motherboard are connected by a plug-in method, effectively reducing the use of wire harnesses, greatly reducing assembly difficulty and EMC (Electromagnetic Compatibility) risks, and providing convenient assembly, reliable connection, and easy subsequent maintenance and replacement. Furthermore, the gold fingers 11 are located on the plug-in portion 14 for electrical connection with the motherboard, resulting in low insertion loss. Compared to common high-speed connectors and ribbon cable combinations, this effectively reduces connection reliability risks and insertion loss introduced by multiple connector mating. Moreover, wire harness shielding measures are generally complex and costly, with disadvantages such as difficulty in implementation in production and unsightly appearance. Using gold fingers 11 plugged into the motherboard can effectively avoid wire harness shielding problems. The circuit board body 13 is provided with an electrical connection part 15.
[0036] The housing 2 has a plug end and a fixed end, which serve as the two ends of the housing 2. The plug end can be electrically connected to a mating connector, and the fixed end is fixedly connected to the circuit board body 13. The plug end can be used as both a connector plug and a connector socket.
[0037] Pin 3 passes through the housing 2 and is electrically connected to the gold finger 11 via the electrical connection part 15. The number of pins 3 can be set as needed, such as multiple pins 3. For example, pins 3 are soldered to the electrical connection part 15. It can be understood that in this embodiment, pins 3 are indirectly connected to the gold finger 11 via the electrical connection part 15, and the electrical connection part 15 is electrically connected to the gold finger 11 via the traces of the adapter circuit board 1, resulting in excellent signal quality and EMC shielding performance. By setting the electrical connection part 15, on the one hand, it facilitates the electrical connection between pins 3 and the adapter circuit board 1; on the other hand, the positions of the housing 2 and pins 3 on the adapter circuit board 1 are more flexible, and can therefore be set accordingly as needed, such as the shape and thickness of the adapter circuit board 1 and the fixed position of the housing 2, which are flexibly adjustable and facilitate structural stacking within the device host.
[0038] Using the connector assembly provided in this application, the fixed end of the housing 2 is fixedly connected to the adapter circuit board 1. The pin 3 passes through the housing 2 and is electrically connected to the gold fingers 11 on the adapter circuit board 1 via the electrical connection part 15. The adapter circuit board 1 can then be electrically connected to the motherboard of the device host via its gold fingers 11, thus achieving an electrical connection between the pin 3 and the motherboard. In summary, the connector assembly provided in this application connects the pin 3 to the motherboard via the adapter circuit board 1. The pin 3 is less prone to deformation, ensuring a reliable electrical connection, thereby improving the reliability of the connector assembly and guaranteeing signal quality. Furthermore, the adapter circuit board 1, connected to the motherboard via the gold fingers 11, is low-cost, wear-resistant, easy to assemble, and convenient for future maintenance and replacement.
[0039] In some embodiments, the adapter circuit board 1 has a first surface and a second surface disposed opposite to each other. The housing 2 is fixedly connected to the circuit board body 13 on the first surface, and the gold fingers 11 are disposed on the first surface and / or the second surface of the insertion portion 14. It is understood that the first surface and the second surface of the adapter circuit board 1 are large planes along its length, the first surface of the insertion portion 14 faces the same direction as the first surface of the adapter circuit board, and the second surface of the insertion portion 14 faces the same direction as the second surface of the adapter circuit board 1. By connecting the housing 2 to the large plane along the length of the adapter circuit board 1, instead of the small plane along the thickness direction of the adapter circuit board 1, and by disposing the gold fingers 11 on the first or second surface of the insertion portion 14, or by disposing the gold fingers on both the first and second surfaces of the insertion portion 14, assembly is simpler, space in the depth direction of the connector assembly can be saved, and the direction of the pins 3 can be changed.
[0040] In some embodiments, the circuit board body 13 and the housing 2 each have a fixing part 121 and a fixing mating part 122 with corresponding position and shape. The engagement of the fixing part 121 and the fixing mating part 122 facilitates the assembly and maintenance of the housing 2 and the circuit board body 13. The fixing part 121 and the fixing mating part 122 can be several mating protrusions and grooves (or through holes) surrounding the pin 3. Since the pin 3 and the electrical connection part 15 are relatively small, they are not easy to assemble quickly and accurately. Therefore, with the assistance of the fixing part 121 and the fixing mating part 122, the connection between the pin 3 and the circuit board body 13 is simpler. In other embodiments, the fixing part 121 and the fixing mating part 122 may not be provided; the pin 3 can be directly inserted into the circuit board body 13 and then soldered. Alternatively, the housing 2 and the adapter circuit board 13 can be directly fixed together by adhesive bonding, high-temperature welding, or other methods.
[0041] In some embodiments, the fixing part 121 or the fixing mating part 122 is disposed around the periphery of the pin 3. It is understood that the fixing part 121 or the fixing mating part 122 surrounds the pin 3, and when multiple pins 3 are provided, the fixing part 121 or the fixing mating part 122 is disposed around the periphery of each pin 3 as a whole. Fixing the housing 2 relative to the adapter circuit board 1 from the periphery ensures the reliability of the connection between the internal pin 3 and the electrical connection part 15. Furthermore, during the insertion and removal of the plug-in part 14 from the motherboard, the housing 2 is the main force-bearing component; that is, the housing 2 is inserted and removed from the motherboard along with the adapter circuit board 1, while the pin 3 experiences relatively less force, further ensuring the reliability of the pin 3 connection.
[0042] For example, the fixing part 121 is provided on the housing 2, and the fixing mating part 122 is provided on the circuit board body 13. The fixing part 121 is welded to the circuit board body 13, and the pin 3 is welded to the electrical connection part 15. The welding area between the electrical connection part 15 and the pin 3 is smaller than the welding area between the fixing part 121 and the circuit board body 13. That is, the housing 2 serves as the main force-bearing component for connecting to the adapter circuit board 1, thereby ensuring a reliable mechanical and electrical connection between the pin 3 and the adapter circuit board 1. Specifically, the fixing part 121 is a welding pin, and the fixing mating part 122 is a through hole provided on the circuit board body 13. During assembly, the pin 3 is inserted into the electrical connection part 15 and welded thereto, and the welding pin is inserted into the tube through hole 12 and welded thereto.
[0043] In some embodiments, the fixed end of the housing 2 surrounds the pin 3, that is, the pin 3 at the end of the housing 2 connected to the adapter circuit board 1 is not exposed. For ease of explanation, the end of the adapter circuit board 1 that abuts against the housing 2 is referred to as the first side of the adapter circuit board 1. That is, the pin 3 is not exposed on the first side of the adapter circuit board 1, so the electromagnetic compatibility performance is better, and thus it is especially suitable for medical devices with strict requirements for electromagnetic compatibility performance.
[0044] In some embodiments, multiple pins 3 and electrical connection parts 15 are correspondingly configured, and the fixing part 121 and fixing mating part 122 are provided with a foolproof structure, so that the housing 2 and the circuit board body 13 can only be fixedly connected in a set posture. In the set posture, multiple pins 3 and electrical connection parts 15 are paired and combined one by one according to their functions. For example, some of the multiple pins 3 are high-definition multimedia pins, some are USB (Universal Serial Bus) pins, and some are power pins. That is, the connector assembly can transmit signals and power at the same time. Specifically, this application integrates three signals, such as HDMI (High Definition Multimedia Interface), USB 2.0, and DC 12V, into an aviation socket with impedance control, which is compatible with high-speed signal quality and power carrying capacity. For example, the connector assembly is a 22-pin connector assembly, which ensures the continuity of the high-speed signal transmission link impedance, while minimizing the number of signals, thereby ensuring both aesthetic appearance and effectively reducing the core diameter of the plug-in wire harness, improving the flexibility of the wire harness. In terms of signal definition, HDMI 2.1 is specifically adopted, replacing HEC (HEC HDMI Ethernet Channel) DATA+ / - with USB 2.0's D+ / - as defined by USB 3.2. HDMI's 5V power supply current is relatively small, so only pin 10 is used for transmission; pin 13 is used as USB_VBUS, and similarly, pin 7 is used as the 12V power supply. The CEC (Consumer Electronics Control) signal is used as HPD (Hot Plug Detection). By providing foolproof structures in the fixing part 121 and the fixing mating part 122, it is easier to determine the position of the housing 2 and the circuit board body 13 when connecting them, facilitating assembly and avoiding misalignment of pins 3 due to relative positional deviation between the housing 2 and the circuit board body 13.
[0045] In some specific examples, the electrical connection portion 15 includes, but is not limited to, pads, vias, etc. Pin 3 can pass through the electrical connection portion 15. In some specific examples, the end of pin 3 does not extend beyond the back of the adapter circuit board 1, meaning pin 3 is not exposed on the back of the adapter circuit board 1, thereby reducing the risk of electromagnetic radiation. To ensure the reliability of the connection between pin 3 and the electrical connection portion 15, in other specific examples, the end of pin 3 protrudes beyond the back of the adapter circuit board 1, with a protrusion height specifically not exceeding 1mm. Compared to conventional 90° bend aviation connector sockets, this significantly reduces the exposed length of pin 3, and the electromagnetic radiation generated by the exposed length can even be ignored.
[0046] In some embodiments, the plug portion 14 includes at least two protrusions 141 extending from the edge of the circuit board body 13, with a notch 142 formed between adjacent protrusions 141. When the connector assembly is connected to the motherboard, the protrusions 141 are used to insert into the slots of the motherboard, while the notch 142 can be positioned with the protrusions in the slots, thereby facilitating the determination of the insertion position during assembly and further improving assembly efficiency.
[0047] In some embodiments, the plug-in terminals of housing 2 are aviation sockets. Aviation sockets offer a simple structure, easy soldering process, and stable connection. For example, the plug-in terminals of housing 2 utilize aviation sockets with impedance control, resulting in excellent signal quality, high integration, aesthetically pleasing appearance, and convenient plugging and unplugging. With aviation sockets at the plug-in terminals of housing 2, and the connector assembly located on the device host, corresponding aviation plugs are provided on devices such as the touchscreen. During connection, the aviation plug is inserted into the aviation socket to make contact and conduction between the pins 3, thereby connecting the touchscreen and other devices to the device host.
[0048] In some embodiments, the plug end of the housing 2 has a groove 21, and the bottom of the groove 21 has a socket 22, with pins 3 disposed within the socket 22. The groove 21 is used for the insertion of the aviation plug; that is, when the aviation socket is connected to the aviation plug, the aviation plug is inserted into the groove 21, and the terminals of the aviation plug are inserted into the socket 22 and make contact with the pins 3 for conduction. The groove 21 and the socket 22 can guide and limit the plug and its terminals, making the connection between the aviation plug and the aviation socket more reliable.
[0049] Based on the connector assembly provided in the above embodiments, this application also provides a device host, which includes a motherboard and any one of the connector assemblies in the above embodiments, wherein the gold fingers 11 of the connector assembly are electrically connected to the motherboard. Since this device host uses the connector assembly in the above embodiments, the beneficial effects of this device host can be found in the above embodiments.
[0050] In some embodiments, the motherboard has a slot, and the connector 14 is inserted into the slot. For example, the slot is a PCIe slot. The adapter circuit board 1 connects to the motherboard via a plug-in connection, effectively reducing the use of wiring harnesses, significantly reducing assembly difficulty and EMC risks, and providing convenient assembly, reliable connection, and easy future maintenance and replacement. Furthermore, the gold fingers 11 are electrically connected to the motherboard, resulting in low insertion loss. Compared to common high-speed connectors and ribbon cables, this effectively reduces connection reliability risks and minimizes insertion loss introduced by multiple connector matings. Moreover, wiring harness shielding measures are generally complex and costly, presenting disadvantages such as difficulty in production implementation and unsightly appearance. Using the gold fingers 11 to connect to the motherboard effectively avoids wiring harness shielding issues.
