Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multi-interface connection structure and medical equipment with an inclined plane. Background Technology

[0002] In some existing medical devices, for aesthetic reasons and to facilitate observation and operation, the display or operating parts are often designed as bevels. Take endoscopic devices as an example... Figure 1 As shown, the display area of ​​its main unit is angled.

[0003] Typically, the display area of ​​a host computer has multiple cable interfaces for connecting to the host computer via cables. These cable interfaces are usually perpendicular to the beveled surface.

[0004] This setup has the following problems: 1. The cable droops at an angle of less than 90 degrees after connecting to the cable interface, causing severe bending of the external cable and reducing its lifespan; 2. The tilted insertion of the cable not only affects the appearance, but also makes it inconvenient to operate when plugging in the cable connector and interface, and increases the risk of damage to the cable interface due to incorrect force direction; 3. The open and tilted upward cable interface is more prone to accumulating dirt and grime, thus affecting the performance and lifespan of the cable interface; At the same time, since multiple cable interfaces are connected to different PCB boards, the stability of the cable interface and PCB board after fixed connection is poor, and there is a risk of poor contact due to shaking. Summary of the Invention

[0005] In view of this, the present invention provides a multi-interface connection structure and medical device with an inclined plane to solve any of the following technical problems caused by the inclined cable interface: severe bending of the connected cable; inconvenient plugging and connection, and the risk of damaging the cable interface; dirt accumulation, affecting the performance and lifespan of the cable interface; poor connection stability between the cable interface and the PCB board.

[0006] In a first aspect, the present invention provides a multi-interface connection structure with an inclined plane, comprising a mounting housing and at least two interface components. The mounting housing has an inclined mounting surface, the angle between the mounting surface and the vertical direction being a first angle, and at least two first mounting holes are provided at intervals on the mounting surface, the axes of the first mounting holes being perpendicular to the mounting surface; the interface components include interface seats, interface bodies, and PCB boards, with multiple interface seats correspondingly disposed in the first mounting holes, each interface seat having a second mounting hole penetrating it, the second mounting hole communicating with the first mounting hole, the axis of the second mounting hole having a second angle between it and the mounting surface, the first angle and the second angle being complementary, the first end of the interface body being disposed in the second mounting hole, the second end of the interface body being connected to the PCB board, and the PCB boards of adjacent interface components being connected.

[0007] Beneficial effects: Since the angle between the axis of the second mounting hole and the mounting surface is complementary to the angle between the mounting surface and the vertical direction, the tilt angle of the axis of the second mounting hole compensates for the tilt angle of the mounting surface relative to the vertical direction. This makes the axis of the interface assembly's insertion hole horizontal, resulting in the following effects: 1. When a cable is connected to the interface, the cable's droop angle is greater than 90 degrees, reducing the degree of external cable bending and ensuring that the cable's lifespan is not affected; 2. Because the interface body is horizontally arranged, it is easy to plug in the cable connector, making operation convenient and reducing damage to the interface; 3. The interface changes from an upward tilt to a horizontal position, making it less prone to dust accumulation and reducing the impact of dust on the interface's performance and lifespan. Simultaneously, the PCB boards of adjacent interface assemblies are interconnected, thus ensuring the connection stability between the interface body and the PCB board and guaranteeing good contact between them.

[0008] In one alternative implementation, multiple interface components are arranged in a stepped manner along a vertically downward direction. The PCB board includes a vertically arranged board body and bosses protruding from the board body toward the side close to the interface body. The bosses of adjacent PCB boards are arranged opposite each other, and the two opposite bosses are fixedly connected.

[0009] Beneficial effects: By setting up bosses, gaps between adjacent interface component boards can be filled, thereby adjusting the horizontal distance between the interface body's plug hole and the mounting surface. The closer the horizontal distance between the interface body's plug hole and the mounting surface, the easier it is to plug in cables.

[0010] In one optional embodiment, the horizontal distance between adjacent board bodies is a first distance, and the horizontal distance between the front end faces of the plug holes of adjacent interface bodies is a second distance, and the first distance and the second distance are equal.

[0011] Beneficial effects: Since the board body is set vertically, and the horizontal distance between adjacent board bodies is equal to the horizontal distance between the front end faces of the plug holes of adjacent interface bodies, the horizontal distance between the front end faces of the plug holes of adjacent interface bodies and the mounting surface is equal. This ensures that the cable connector is plugged into any interface body to the same depth, guaranteeing proper insertion, good contact, and stable connection.

[0012] In one alternative implementation, the two opposing bosses are welded together, or the two opposing bosses are connected by a plug-in structure.

[0013] Beneficial effects: The two opposing bosses are welded together, allowing for a cost-effective and secure connection between the two PCB boards. The two opposing bosses are connected via a plug-in structure, ensuring high positioning accuracy, facilitating installation, and achieving a secure connection between the two PCB boards.

[0014] In one optional embodiment, the plug-in structure includes a male plug and a female plug that cooperate with each other. The male plug and the female plug are respectively provided on two opposite protrusions. The male plug and the female plug are plugged in to fix the adjacent plate bodies together.

[0015] Beneficial effects: The use of male and female plug-in connectors makes plugging in convenient, easy to operate, and provides high positioning accuracy.

[0016] In one optional embodiment, the interface base includes a plug portion that mates with a first mounting hole and a limiting portion connected to the plug portion. A second mounting hole passes through the plug portion and the limiting portion. The plug portion is inserted into the first mounting hole of the mounting housing. The size of the limiting portion is larger than the size of the plug portion. A first stepped surface is formed between the limiting portion and the plug portion. The first stepped surface abuts against the inner end face of the first mounting hole.

[0017] Beneficial effect: With this setting, when the first stepped surface and the inner end face of the first mounting hole abut, a limit is formed between the interface seat and the mounting housing, indicating that the socket seat is installed in place.

[0018] In one alternative embodiment, a third included angle exists between the axis of the second mounting hole and the insertion portion, and the third included angle is equal to the first included angle.

[0019] Beneficial effects: With this configuration, since the axis of the interface seat is perpendicular to the mounting surface, and the third included angle between the axis of the second mounting hole and the interface seat is equal to the first included angle between the mounting surface and the vertical direction, the second mounting hole is perpendicular to the vertical direction, i.e., the second mounting hole is horizontal. This makes the axis of the insertion hole of the interface body located in the second mounting hole horizontal, thereby enabling the interface assembly to meet the requirements of horizontal insertion, ensuring convenient insertion, proper insertion, and good contact.

[0020] In one optional embodiment, the second mounting hole includes a first hole segment near the mounting surface and a second hole segment away from the mounting surface. The size of the second hole segment is larger than that of the first hole segment. A second stepped surface is formed between the second hole segment and the first hole segment. The interface body is inserted into the second hole segment, and the front end of the interface body abuts against the second stepped surface.

[0021] Beneficial effects: This design creates a limit between the front end of the interface body and the second stepped surface. When the front end of the interface body abuts against the second stepped surface, it indicates that the interface body is installed in place. Furthermore, because the rear end of the interface body is connected to the PCB board, both ends of the interface body are also limited, ensuring the positioning and fixation of the interface body.

[0022] In one alternative implementation, a limiting block protrudes from the side of the interface socket facing the PCB board, and the limiting block abuts against the PCB board.

[0023] Beneficial effects: This configuration creates an abutment limit between the limiting block and the PCB board body, allowing the PCB board body to be positioned and improving its installation accuracy.

[0024] Secondly, the present invention also provides a medical device, including a host and a multi-interface connection structure of an inclined plane according to any of the above technical solutions, wherein the mounting housing is disposed on the host, or the housing of the host is the mounting housing.

[0025] Beneficial effects: Since the medical device includes a multi-interface connection structure with an inclined plane, it has the same effect as the multi-interface connection structure with an inclined plane, which will not be elaborated here. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0041] According to an embodiment of the present invention, in one aspect, a multi-interface connection structure with an inclined plane is provided, including a mounting housing 1 and at least two interface components 2. The mounting housing 1 has an inclined mounting surface 101, the mounting surface 101 forming a first angle α with the vertical direction, and at least two first mounting holes 102 are provided at intervals on the mounting surface 101, the axis of the first mounting holes 102 being perpendicular to the mounting surface 101; the interface components 2 include an interface base 201, an interface body 202, and a PCB board 3, a plurality of interface bases 201 being disposed in the first mounting holes 102 in a corresponding manner, the interface base 201 being provided with a second mounting hole 2011 passing through it, the second mounting hole 2011 communicating with the first mounting hole 102, the axis of the second mounting hole 2011 being at a second angle β with the mounting surface 101, the first angle α and the second angle β being complementary, the first end of the interface body 202 being disposed in the second mounting hole 2011, the second end of the interface body 202 being connected to the PCB board 3, and the PCB boards 3 of adjacent interface components 2 being connected.

[0042] Since the angle between the axis of the second mounting hole 2011 and the mounting surface 101 is complementary to the angle between the mounting surface 101 and the vertical direction, the tilt angle of the axis of the second mounting hole 2011 compensates for the tilt angle of the mounting surface 101 relative to the vertical direction. This makes the axis of the insertion hole of the interface assembly 2 horizontal, thus achieving the following effects: 1. When a cable is connected to the interface, the cable drooping angle is greater than 90 degrees, reducing the degree of external cable bending and ensuring that the cable's service life is not affected; 2. Because the interface body 202 is horizontally arranged, it is convenient to plug in the cable connector and interface, making operation easy and reducing damage to the interface; 3. The interface changes from tilted upwards to horizontal, making it less prone to dust accumulation and reducing the impact of dust on the interface's performance and lifespan. Simultaneously, the PCB boards 3 of adjacent interface assemblies 2 are interconnected, thus ensuring the connection stability between the interface body 202 and the PCB board 3 and guaranteeing good contact between them.

[0043] Specifically, from Figure 1 As shown in the diagram, multiple interface components 2 are arranged vertically at intervals on the mounting surface 101. Taking two USB interface components 2 as an example, the two interface components 2 are arranged vertically at intervals on the mounting surface 101.

[0044] Specifically, the first end of the interface body 202 is the end closer to the mounting surface 101, and the second end of the interface body 202 is the end farther away from the mounting surface 101.

[0045] In one embodiment, multiple interface components 2 are arranged in a stepped manner along the vertically downward direction. The PCB board 3 includes a vertically arranged board body 301 and a boss 302 protruding from the board body 301 toward the side close to the interface body 202. The bosses 302 of adjacent PCB boards 3 are arranged opposite to each other, and the two opposite bosses 302 are fixedly connected.

[0046] Because the mounting surface 101 is sloped, the second ends of the interface bodies 202 of two adjacent interface components 2 are staggered in a stepped manner as they descend along the mounting surface 101. There is a horizontal gap between the second ends of adjacent interface bodies 202. Since the board body 301 is vertically arranged, and the second ends of the interface bodies 202 connect to the board body, there is a horizontal gap between adjacent board bodies 301. By setting a boss 302 to connect two board bodies, a supporting effect can be provided for the two adjacent board bodies, improving the installation stability of the board bodies. The closer the horizontal distance between the insertion hole of the interface component 2 and the mounting surface 101, the easier it is to insert cables.

[0047] Specifically, the PCB board 3 body 301 is connected to conductive wires 5.

[0048] In one embodiment, the horizontal distance between adjacent board bodies is a first distance, and the horizontal distance between the front end faces of the plug holes of adjacent interface bodies 202 is a second distance, and the first distance and the second distance are equal.

[0049] With this configuration, since the board body is set vertically, and the horizontal distance between adjacent board bodies is equal to the horizontal distance between the front end faces of the plug holes of adjacent interface bodies 202, the horizontal distance between the front end faces of the plug holes of adjacent interface bodies 202 and the mounting surface is equal. This ensures that when the cable connector is plugged into any interface body 202, the insertion depth is the same, guaranteeing proper insertion, good contact, and stable connection.

[0050] In one embodiment, the two opposing bosses 302 are welded together, or the two opposing bosses 302 are connected by a plug-in structure.

[0051] The two opposing bosses 302 are welded together, which can fix the two PCB boards 3 together at a lower cost. The two opposing bosses 302 are connected by a plug-in structure, which has high positioning accuracy, facilitates installation, and achieves a fixed connection between the two PCB boards 3.

[0052] In one embodiment, the plug-in structure includes a male plug-in 304 and a female plug-in 305 that cooperate with each other. The male plug-in 304 and the female plug-in 305 are respectively provided on two opposite bosses 302. The male plug-in 304 and the female plug-in 305 are plugged in to fix the adjacent plate bodies 301 together.

[0053] The connection uses a male snap-fit ​​304 and a female snap-fit ​​305, which is convenient to plug in, easy to operate, and has high positioning accuracy.

[0054] In one embodiment, the plate body 301 is provided with a third mounting hole 303 that passes through it, and the interface body 202 and the plate body 301 are connected by bolts 4.

[0055] The system uses four bolts for connection, which is simple in structure and easy to operate, and achieves a fixed and conductive connection between the interface body 202 and the board body 301.

[0056] In one embodiment, the interface base 201 includes a plug-in portion 2012 that mates with a first mounting hole 102 and a limiting portion 2013 connected to the plug-in portion 2012. A second mounting hole 2011 passes through the plug-in portion 2012 and the limiting portion 2013. The plug-in portion 2012 is inserted into the first mounting hole 102 of the mounting housing 1. The size of the limiting portion 2013 is larger than the size of the plug-in portion 2012. A first stepped surface 2014 is formed between the limiting portion 2013 and the plug-in portion 2012. The first stepped surface 2014 abuts against the inner end face of the first mounting hole 102.

[0057] With this configuration, when the first stepped surface 2014 and the inner end face of the first mounting hole 102 abut against each other, a limit is formed between the interface seat 201 and the mounting housing 1, indicating that the socket seat is installed in place.

[0058] In one embodiment, there is a third included angle γ between the axes of the second mounting hole 2011 and the insertion part 2012, and the third included angle γ is equal to the first included angle α.

[0059] With this configuration, since the axis of the interface base 201 is perpendicular to the mounting surface 101, and the third included angle γ between the axis of the second mounting hole 2011 and the interface base 201 is equal to the first included angle α between the mounting surface 101 and the vertical direction, the second mounting hole 2011 is perpendicular to the vertical direction, that is, the second mounting hole 2011 is horizontal. This makes the axis of the insertion hole of the interface body 202 located in the second mounting hole 2011 horizontal, thereby enabling the interface assembly 2 to meet the requirements of horizontal insertion, ensuring convenient insertion, proper insertion, and good contact.

[0060] In one embodiment, the second mounting hole 2011 includes a first hole segment near the mounting surface 101 and a second hole segment away from the mounting surface 101. The size of the second hole segment is larger than the size of the first hole segment. A second stepped surface 203 is formed between the second hole segment and the first hole segment. The interface body 202 is inserted into the second hole segment, and the front end of the interface body 202 abuts against the second stepped surface 203.

[0061] This configuration creates a limiting relationship between the front end of the interface body 202 and the second stepped surface 203. When the front end of the interface body 202 abuts against the second stepped surface 203, it indicates that the interface body 202 is installed in place. Furthermore, because the rear end of the interface body 202 is connected to the board body 301 of the PCB board 3, both ends of the interface body 202 are limited, ensuring the positioning and fixation of the interface body 202.

[0062] In one embodiment, the interface base 201 has a limiting block 204 protruding from the side facing the PCB board 3, and the limiting block 204 abuts against the PCB board 3.

[0063] This configuration allows the limiting block 204 and the board body 301 of the PCB board 3 to form an abutment limit, abutting the board body 301 and the limiting block 204 of the interface seat 201, thereby enabling the positioning of the board body 301 of the PCB board 3 during installation and improving the installation accuracy of the board body 301 of the PCB board 3.

[0064] In one embodiment, a limiting post 103 is provided on the inner wall of the mounting housing, and the limiting post 103 abuts against the limiting part 2013 of the interface seat 201. This can further improve the positioning accuracy of the interface seat 201 during installation.

[0065] In one embodiment, a threaded hole is provided on the limiting post 103, and a corresponding connecting hole is also provided on the limiting part 2013 of the interface seat 201. When the interface seat 201 and the limiting post 103 abut and cooperate, their connecting holes correspond. After the bolt 4 passes through the connecting hole on the interface seat 201, it is tightened into the threaded hole of the mounting housing 1 to fix the interface seat 201 and the mounting housing 1.

[0066] According to an embodiment of the present invention, another aspect provides a medical device, including a host 6 and a multi-interface connection structure of an inclined plane according to any of the above technical solutions, wherein a mounting housing 1 is disposed on the host 6, or the housing of the host 6 is the mounting housing 1.

[0067] Since medical devices include multi-interface connection structures with inclined planes, which have the same effect as multi-interface connection structures with inclined planes, they will not be elaborated further here.

[0068] Specifically, the main unit 6 includes a front panel 601 and a front shell 602. The front panel 601 is disposed on the front shell 602, and the mounting housing 1 is either the front shell 602 or the mounting housing 1 is disposed on the front shell 602.
