Description

Technical Field

[0001] This invention belongs to the field of connector cable technology, and specifically relates to a multi-channel adapter cable assembly for magnetic resonance equipment. Background Technology

[0002] In medical devices such as MRI scanners, electrical connectors and components are typically used to connect the portable handheld device 3, the hospital bed 2, and the main body of the device 1, synchronously transmitting radio frequency and current signals. Their basic structure is as follows: Figure 1 As shown. The headboard 201 of the hospital bed 2 is equipped with a connector and is connected to the main body of the device 1 via a headrest connection. The footboard 202 is equipped with a connector and is connected to the portable handheld device 3 via a headrest connection.

[0003] With technological advancements, equipment is evolving towards higher density and modularity, with the number and functionality of transmission channels continuously increasing. Simultaneously, there is a frequent need for movement and dragging between the hospital bed (2) and the MRI machine (1). Therefore, as... Figure 2 As shown, a cable chain assembly 4 is required to protect the cables between the hospital bed body 2 and the equipment body 1, placing higher demands on the bending resistance and bending radius of the cables in the cable chain assembly 4. The cables in the cable chain assembly 4 are generally circular cross-section cables, and the wire diameter increases with the number of transmission channels. Given the frequent bending and unfolding of the cable chain, the increased bending radius of the circular cables results in the cable chain assembly occupying more space.

[0004] In addition, such as Figure 2 As shown, the bed assembly 5 used to connect the cable chain assembly 4 and the portable handheld device 3 on the current MRI equipment bed is a single double-ended cable assembly. The two ends of the cable are a head-end connector 501 and a foot-end connector 502, respectively. The head-end connector 501 is connected to the cable chain socket end 402 in the cable chain assembly 4 via a head-end connection, and the foot-end connector 502 is connected to the portable handheld device 3 via a head-end connection. The cable chain plug end 401 in the cable chain assembly 4 is connected to the device body 1 via a head-end connection.

[0005] However, this connection method has the following problems:

[0006] 1. To meet the connection requirements of multiple portable handheld devices 3, multiple bed frame components 5 need to be connected in parallel. If a problem occurs at the connector end and needs to be replaced, the entire assembly needs to be replaced, resulting in high maintenance costs.

[0007] 2. Currently, the bed assembly 5 and the cable chain assembly 4 are connected via a headstock, with a round pin and round hole contact pair and a 12-channel connector. With the increasing demand for multi-channel connectors, the connector connected to the headstock has to be larger due to the increased number of contact pairs, which is detrimental to the utilization of bed space. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-channel adapter cable assembly for magnetic resonance imaging (MRI) devices. While increasing the number of transmission channels without affecting transmission performance, the structure is optimized to reduce the size of connectors and space occupation. Furthermore, the adapter components facilitate product maintenance and replacement.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: a multi-channel adapter cable assembly for a magnetic resonance imaging (MRI) device, including a drag chain unit, wherein the drag chain cable in the drag chain unit is a flat drag chain cable, which is composed of multiple strands of round wire bundles laid flat, one end of the drag chain cable is connected to the main body of the MRI device through a connector, and the other end of the drag chain cable is connected to the bed unit through a connector.

[0010] The bed unit is laid on the bed of the magnetic resonance equipment. The bed unit includes a bed cable. The end of the bed cable near the head of the bed is connected to the drag chain cable through a connector, and the end of the bed cable near the foot of the bed is connected to the adapter component.

[0011] The adapter component includes a footboard socket, a mating male PCB adapter, and a female PCB adapter. The footboard socket and the male or female PCB adapter are pre-assembled into a prefabricated module, which is then plugged into the female or male PCB adapter connected to the cable on the bed frame.

[0012] Its beneficial effects are: the drag chain cable is set as a flat drag chain cable, which can have a smaller bending radius under the same channel, enabling it to work in a smaller space without affecting transmission performance; after using the adapter component, the end socket of the bed end and the PCB adapter male or PCB adapter female end are pre-assembled into a prefabricated module, which facilitates maintenance or replacement during equipment use. Moreover, after using the adapter component, it can be used for various cable outlet methods, while ensuring that the module positions of the head end and the end end of the bed can be aligned. The head end and end end modules can also be laid out on both sides or ends of the bed, making the overall layout more coordinated and unified.

[0013] Furthermore, the drag chain cable and the bed cable are connected by a high-density connector, which includes a high-density plug and a high-density socket. The high-density plug and the high-density socket are L-shaped, and when they are plugged into place, the whole structure is rectangular.

[0014] Its beneficial effects are: the use of high-density plugs and high-density sockets can increase the number of channels, and through the optimization of the shape and structure, the volume is more compact after plugging, and the space utilization rate is higher.

[0015] Furthermore, the high-density plug and high-density socket have a PCB board inside. The PCB board on the high-density plug and high-density socket is soldered to the cable to be connected. The soldering area of ​​the PCB board is coated with UV glue to fix and protect the solder joints and the wires of the solder joint accessories.

[0016] Its beneficial effects are: by soldering the contacts of plugs or sockets onto the PCB board, high-density connections can be achieved, and the UV adhesive in the soldering area can fix and protect all the wires of the solder joints and their accessories, ensuring the reliability and stability of the connection.

[0017] Alternatively, when the drag chain cable is connected to the high-density plug, the high-density socket is connected to the bed frame cable.

[0018] Alternatively, when the drag chain cable is connected to the high-density socket, the high-density plug is connected to the bed frame cable.

[0019] Its beneficial effect is that it provides two implementation methods, making it easy to choose which one to use.

[0020] Alternatively, the prefabricated module includes a footboard socket and a male PCB adapter, the female PCB adapter being connected to the bed frame cables.

[0021] Alternatively, the prefabricated module includes a socket at the foot of the bed and a female PCB adapter, the male PCB adapter being connected to the bed frame cable.

[0022] Its beneficial effect is that it provides two implementation methods, making it easy to choose which one to use.

[0023] Furthermore, for the male and female PCB adapter terminals, the pad area of ​​the PCB board is designed in the middle of the board, and the empty space around the pad area is used for connection with the PCB board fixing device.

[0024] Its beneficial effects are: it facilitates better fixation of the PCB board and avoids loosening of the PCB board caused by multiple insertion or separation processes.

[0025] Furthermore, the PCB board of the male or female PCB adapter of the adapter component has multiple pads distributed on it. The arrangement of the pads is adapted to the wire inlet direction in the bed cable so that the soldered wires are laid flat on the PCB board.

[0026] Its beneficial effects are: the soldering of the PCB board and the cable will increase the size and thickness of the adapter part, which will affect the space. The distributed design of the solder pads can adapt to different wire exit directions, so that the wires can be laid flat on the PCB board after soldering, saving assembly space.

[0027] Furthermore, the PCB board of the male or female PCB adapter of the adapter component is also provided with mounting holes for the transmitting contact component.

[0028] Its beneficial effects are: the distributed design of the pads can leave space for the mounting holes of the transmitter contact components, allowing users to use the transmitter adapter socket as needed to achieve compatibility with the transmitter function.

[0029] The beneficial effects of the present invention are: under the premise of increasing the number of transmission channels without affecting transmission performance, the present invention reduces the size of connectors and space occupation through structural optimization, and facilitates product maintenance and replacement through the setting of adapter components.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0044] See attached document Figure 3 As shown, a multi-channel adapter cable assembly for a magnetic resonance imaging (MRI) device includes a cable chain unit 6 and a bed unit 7. The cable chain unit 6 includes a cable chain cable 9, a cable chain plug 8, and a high-density socket 10. The bed unit 7 includes a high-density plug 11, a bed cable 12, and an adapter component. The high-density plug 11 and the high-density socket 10 are connected by plugging and connecting. The cable chain plug 8 is used to connect to the device body 1, and the adapter component is used to connect to a portable handheld device 3.

[0045] like Figure 4 , 5 As shown in Figure 6, the high-density plug 11 and high-density socket 10 are L-shaped, and when they are plugged in, they form a cuboid shape. Therefore, the combined size is more compact, and the space utilization is higher. A PCB board is installed inside the high-density plug 11 and high-density socket 10. The PCB board on the high-density plug 11 and high-density socket 10 is soldered to the cables to be connected. The contacts on the high-density plug 11 and high-density socket 10 are soldered to their corresponding PCB boards, and UV glue is applied to the soldering area of ​​the PCB board to fix and protect the solder joints and the wires around them. By soldering contacts to the PCB board, multi-channel signal transmission with more than 12 channels can be achieved, such as 24-channel signal transmission. Furthermore, through shape optimization of the high-density plug 11 and high-density socket 10, while achieving higher channel signal transmission, the connector size is more compact, improving space utilization.

[0046] like Figure 7As shown, the cable chain unit 6 mainly includes a cable chain cable 9 and a high-density socket 10. The PCB board of the high-density socket 10 is connected to one end of the cable chain cable 9, and the other end of the cable chain cable 9 is connected to a cable chain plug. The cable chain plug uses a conventional plug connector with round pins as contacts, and therefore is not shown in the figure. The cable chain cable 9 is a flat cable chain cable, composed of several strands of round wires laid flat, with a bending radius (e.g., ...). Figure 8 As shown, it has only 50% of the capacity of a round cable carrier with the same number of channels. Therefore, with the same number of channels, a flat cable carrier can operate in a smaller space than a round cable carrier without affecting transmission performance.

[0047] For example Figure 3 , Figure 9 , Figure 10 As shown, the adapter components in the bed unit 7 include a footboard socket 15, a mating PCB adapter male terminal 14, and a PCB adapter female terminal 13. The footboard socket 15 and the PCB adapter male terminal 14 are pre-assembled together. The PCB adapter female terminal 13 is connected to the bed frame cable 12 of the bed unit 7, and the bed frame cable 12 is connected to the high-density plug 11 at the headboard. Thus, the wiring connection between the headboard and footboard can be achieved through the plug-in connection of the PCB adapter male terminal 14 and the PCB adapter female terminal 13. Furthermore, the pre-assembled footboard socket 15 and the PCB adapter male terminal 14 can serve as a prefabricated module, making it a convenient product for maintenance or replacement during equipment use.

[0048] Understandable Figure 9 In the first embodiment, the bed end socket 15 and the PCB adapter male terminal 14 are pre-assembled together as a prefabricated module. In other embodiments, the bed end socket 15 and the PCB adapter female terminal 13 can also be pre-assembled together as a prefabricated module. In this case, the PCB adapter male terminal 14 needs to be connected to the bed cable 12 in the bed unit 7.

[0049] Similarly, the positions of the high-density plugs 11 and high-density sockets 10 on the cable chain 9 and the bed frame cable 12 can be interchanged. For example, the cable chain 9 can be configured to have the high-density plugs 11 and the high-density sockets 10 on the bed frame cable 12 connected in a plug-in manner.

[0050] The bed unit 7, equipped with an adapter, can be adapted to various cable exit methods (such as...). Figure 11 (As indicated by the arrow), this ensures that the modules at the head and foot of the bed are aligned. The head and foot modules can also be placed on the sides or ends of the bed frame, resulting in a more harmonious and unified overall layout. The "head and foot modules" mentioned here refer to the foot-end socket 15 located at the foot of the bed and the high-density socket 10 or high-density plug 11 located at the head of the bed. Figure 9 ,10 As shown, four bed units are arranged on the bed body at the same time, and the bed cables 12 of the four bed units have different outgoing directions.

[0051] In other embodiments, preferably, for the PCB adapter male terminal 14 and the PCB adapter female terminal 13, the pad area of ​​the PCB board is designed in the middle of the board, and the surrounding space of the pad area can be provided for the fixing device to fix the PCB board. This can form a reliable support for the PCB board during the insertion or separation of the PCB adapter male terminal 14 and the PCB adapter female terminal 13.

[0052] After the PCB board of the adapter male terminal 14 or PCB adapter female terminal 13 is soldered to the bed cable 13, if the wires are soldered to the same pad, the size and thickness of the adapter part will increase, requiring a certain amount of assembly space. Therefore, to solve this problem, in other embodiments, multiple distributed pads are used on the PCB board, and the arrangement of the pads on the PCB board is adjusted according to the outgoing direction of the bed cable, so that different pads can be adapted to different outgoing directions of the wires, and the soldered wires can be laid flat on the PCB board, saving assembly space.

[0053] In addition, the PCB board of the male or female PCB adapter of the adapter component is also provided with mounting holes for the transmitter contact component, which can be put into use according to user needs and achieve compatibility with the transmitter function.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of the present invention with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the protection scope of the pending claims.
