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 sloped.

[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, at least two interface components, and a PCB board. 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 spaced apart on the mounting surface, the axes of the first mounting holes being perpendicular to the mounting surface; the interface components include interface seats and interface bodies, multiple interface seats are correspondingly disposed within 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 with the mounting surface, the first angle and the second angle being complementary, and the interface body being disposed within the second mounting hole; all multiple interface components are connected to the PCB board.

[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 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, since multiple interface assemblies are connected to the same PCB board, the connection stability between the interface assemblies and the PCB board is guaranteed, ensuring good contact between them.

[0008] In one alternative embodiment, the PCB board includes a board body and at least one boss disposed on the board body. The boss has a first end face facing away from the board body. In a vertically downward direction, the distance between the first end face of a plurality of bosses and the board body increases. An interface assembly is connected to the board body directly or through the boss.

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

[0010] In one alternative embodiment, the horizontal distance between the first end face of the first boss and the plate body is a first distance, or the horizontal distance between the first end faces of two adjacent bosses is a first distance, and the horizontal distance between the front end faces of the plug holes of adjacent interface components is a second distance, wherein the first distance and the second distance are equal.

[0011] Beneficial effects: This design ensures that the horizontal height difference between the boss and the plate body, or between adjacent bosses, compensates for the horizontal distance difference between the front ends of the insertion holes of two adjacent interface components. This results in equal horizontal spacing between the front ends of the insertion holes of interface components at different positions on the mounting surface and the mounting surface, thereby ensuring proper insertion, good contact, and stable connection.

[0012] In one alternative embodiment, the boss and the plate body are integrally formed, or the boss and the plate body are welded together.

[0013] Beneficial effects: The boss and the plate body are integrally formed, simplifying the assembly process; the boss and the plate body are welded together, resulting in low cost.

[0014] In one optional embodiment, both the plate body and the boss are provided with a third mounting hole, and the third mounting hole on the boss passes through the boss and the plate body; the interface body and the plate body are connected by bolts, or the interface body and the boss are connected by bolts.

[0015] Beneficial effects: The bolted connection is simple in structure and easy to operate, realizing the connection between the interface body and the plate body.

[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 embodiment, the interface socket has a protrusion on the side facing the PCB board, and the protrusion abuts against the PCB board, or the protrusion abuts against a boss.

[0023] Beneficial effects: This design creates a contact limit between the interface socket and the PCB board body. When the board body and the protrusion of the interface socket abut against each other, or when the boss of the PCB board abuts against the protrusion of the interface socket, the installation of the PCB board body can be positioned, thus improving the installation accuracy of the PCB board body.

[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, a multi-interface connection structure with an inclined plane is provided, including a mounting housing 1, at least two interface components 2, and a PCB board 3. 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 spaced apart 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 and an interface body 202, multiple interface bases 201 being disposed one-to-one in the first mounting holes 102, the interface base 201 having a second mounting hole 2011 penetrating therethrough, the second mounting hole 2011 communicating with the first mounting hole 102, the axis of the second mounting hole 2011 having a second angle β with the mounting surface 101, the first angle α and the second angle β being complementary, and the interface body 202 being disposed in the second mounting hole 2011; multiple interface components 2 are all connected to the PCB board 3.

[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, since multiple interface assemblies 2 are connected to the same PCB board 3, the connection stability between the interface assembly 2 and the PCB board 3 can be guaranteed, ensuring 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] In one embodiment, the PCB board 3 includes a board body 301 and at least one boss 302 disposed on the board body 301. The boss 302 has a first end face 3021 facing away from the board body 301. In the vertically downward direction, the distance between the first end face 3021 of the plurality of bosses 302 and the board body 301 increases. The interface component 2 is directly or through the bosses 302 connected to the board body 301.

[0045] Because the mounting surface 101 is sloped, the ends of adjacent interface components 2 near the PCB board 301 are staggered in a stepped manner as they descend along the mounting surface 101. There is a horizontal gap between the ends of the two interface components 2 near the PCB board 301. Since the PCB board 301 is vertically arranged, and the distance between different interface components 2 and the PCB board 301 varies, a boss 302 can be provided to fill the gap between the interface component 2 and the PCB board 301, thereby adjusting the horizontal distance between the interface component 2's insertion hole and the mounting surface 101. The closer the horizontal distance between the interface component 2's insertion hole and the mounting surface 101, the easier it is to connect cables. When the interface component 2 is close to the PCB board 301, the interface component 2 can be directly connected to the PCB board 301, such as... Figure 3The interface component 2 is located at the top. When the distance between the interface component 2 and the board body 301 is large, a boss 302 is provided on the board body 301, and the interface component 2 is connected to the boss 302, thereby realizing the connection with the board body 301. The thickness of the boss 302, that is, the distance between the first end face 3021 of the boss 302 and the board body 301, can be adjusted according to actual needs.

[0046] Specifically, the PCB board 3 body 301 is connected to conductive wires 5.

[0047] In one embodiment, the horizontal distance between the first end face 3021 of the first boss 302 and the plate body 301 is the first distance L1, or the horizontal distance between the first end faces 3021 of two adjacent bosses 302 is the first distance L1, and the horizontal distance between the front end faces of the plug holes of adjacent interface components 2 is the second distance L2, and the first distance L1 and the second distance L2 are equal.

[0048] This configuration ensures that the horizontal height difference between the boss 302 and the plate body 301, or the horizontal height difference between adjacent bosses 302, compensates for the horizontal distance difference between the front ends of the insertion holes of two adjacent interface components 2. This makes the horizontal distance between the front ends of the insertion holes of the interface components 2 at different positions on the mounting surface 101 and the mounting surface 101 equal, thereby ensuring proper insertion, good contact, and stable connection.

[0049] In one embodiment, the boss 302 and the plate body 301 are integrally formed, or the boss 302 and the plate body 301 are welded together.

[0050] The boss 302 and the plate body 301 are integrally formed, which simplifies the assembly process; the boss 302 and the plate body 301 are welded together, which reduces costs.

[0051] In one embodiment, both the plate body 301 and the boss 302 are provided with a third mounting hole 303, and the third mounting hole 303 on the boss 302 passes through the boss 302 and the plate body 301; the interface body 202 and the plate body 301 are connected by bolts 4, or the interface body 202 and the boss 302 are connected by bolts 4.

[0052] When the interface component 2 is close to the board body 301 of the PCB board 3, the interface component 2 and the board body 301 are directly connected. Specifically, a third mounting hole 303 is provided on the board body 301 at the position corresponding to the interface component 2. A bolt 4 passes through the third mounting hole 303 to fix the interface body 202 in the interface component 2 to the board body 301 and achieve electrical connection. When the interface component 2 is far from the board body 301 of the PCB board 3, a boss 302 is provided at the corresponding position on the PCB board 3. A third mounting hole 303 is provided on the boss 302, penetrating both the boss 302 and the board body 301. A bolt 4 passes through the board body 301 and the boss 302 and connects to the interface body 202, achieving fixation and electrical connection between the interface body 202 and the board body 301. The bolt 4 connection is simple in structure and easy to operate.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In one embodiment, the interface base 201 has a protrusion 204 on the side facing the PCB board 3, and the protrusion 204 abuts against the PCB board 3, or the protrusion 204 abuts against the boss 302.

[0060] This configuration allows the interface bracket 201 and the board body 301 of the PCB board 3 to form an abutment limit, so that when the board body 301 abuts the protrusion 204 of the interface bracket 201, or when the boss 302 of the PCB board 3 abuts the protrusion 204 of the interface bracket 201, the installation of the board body 301 of the PCB board 3 can be positioned, thereby improving the installation accuracy of the board body 301 of the PCB board 3.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.
