Abstract
Description
Technical Field
[0001] This utility model relates to the field of embedded computer-aided components, specifically to embedded computer bus devices. Background Technology
[0002] Every microprocessor needs to connect to a certain number of components and peripherals. However, if each component and each peripheral were directly connected to the CPU using a separate set of lines, the wiring would be intricate and even difficult to implement. To simplify hardware circuit design and system architecture, a common set of lines, configured with appropriate interface circuits, is used to connect to each component and peripheral. This shared set of connection lines is called a bus. Using a bus structure facilitates the expansion of components and devices, and in particular, establishing a unified bus standard makes it easy to interconnect different devices.
[0003] Specifically, in microcomputers such as embedded computers, buses generally include internal buses, system buses, and external buses. The internal bus is the bus between the various peripheral chips and the processor inside the microcomputer, used for chip-level interconnection; while the system bus is the bus between the various plug-in boards and the system board in the microcomputer, used for plug-in board-level interconnection; the external bus is the bus between the microcomputer and external devices. As a device, the microcomputer exchanges information and data with other devices through this bus, and it is used for device-level interconnection.
[0004] In the actual design of the system bus, the current system bus is usually in a state of direct exposure after plugging in. This makes the system bus wires susceptible to electromagnetic interference and unstable operation when the embedded computer is used in a complex industrial environment. If a shield is directly placed on the outside of the system bus wires for electromagnetic shielding, the wires will not be able to dissipate heat effectively, which will cause the system bus wires to become unstable due to temperature rise. Utility Model Content

By covering the bus cable body with a shielding shell of the interference shielding component, the bus cable body can be protected against electromagnetic interference. At the same time, the inner and outer top surfaces of the shielding shell are respectively covered and fixed with flexible heat-conducting plates and spaced heat dissipation fins. In this way, the heat of the bus cable body can be conducted to the heat dissipation fins through the flexible heat-conducting plate and the shielding shell for heat dissipation by contacting the flexible heat-conducting plate with the outside of the bus cable body. This enriches the functionality of the interference shielding component, as detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The embedded computer bus device provided by this utility model includes a bus cable body. The bus cable body is flat and its length is arranged longitudinally. The outer cover of the bus cable body is provided with an interference shielding component with heat conduction and heat dissipation function, so as to provide dual protection of the bus cable body by the interference shielding component and heat dissipation.
[0008] The interference shielding component is provided with corner fixing components at all four corners, which are used to quickly assemble and fix the interference shielding component to the outside of the bus cable body.
[0009] Preferably, both the front and rear ends of the bus cable body are electrically connected to bus plugs for plugging into and electrically connecting with corresponding plug-in boards and system boards.
[0010] Preferably, the interference shielding assembly includes a shielding shell and a flexible heat-conducting plate.

[0013] Preferably, each of the corner fixing components includes an insulating bracket and a fixing slot.

[0016] Preferably, the insulating card holders are all elastic rubber seats, and the corresponding corners of the shielding cover are detachably engaged with the corresponding fixing slots by means of tensioning fit.
[0017] Using the aforementioned embedded computer bus device, specifically in the application of the bus cable body in an embedded computer, the interference shielding component with heat conduction and heat dissipation functions is provided on the outside of the bus cable body. This allows the bus cable body to be protected against electromagnetic interference by the shielding shell of the interference shielding component covering the outside of the bus cable body. Simultaneously, the inner and outer top surfaces of the shielding shell are respectively covered and fixed with a flexible heat-conducting plate and spaced-apart heat dissipation fins.

It achieves efficient heat dissipation while providing shielding protection for the bus cable body, which is beneficial for improving the overall operational stability of the embedded computer. Furthermore, since the interference shielding component has heat dissipation fins at all four corners...

This facilitates the use of the interference shielding component to cover the bus cable body for shielding protection and heat dissipation, while also facilitating subsequent maintenance and inspection of the bus cable body after the interference shielding component is removed. Furthermore, since the insulating bracket of the corner fixing assembly is an elastic rubber bracket, the design of the insulating bracket allows for both pressing and pulling of the four corners of the shielding cover with the fixing slots, as well as pulling and disassembling.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0033] See Figures 1-8 As shown, this utility model provides an embedded computer bus device, including a bus cable body 3. The bus cable body 3 has a flat design and is arranged longitudinally along its length. The outer cover of the bus cable body 3 is provided with an interference shielding component 1 with heat conduction and heat dissipation functions, so as to provide dual protection for the bus cable body 3 through the interference shielding component 1 for shielding and heat dissipation. Specifically, the interference shielding component 1 includes a shielding shell 102 and a flexible heat-conducting plate 103. The shielding shell 102 is a rectangular box that is open at the front, back, and bottom, and the shielding shell 102 covers the outside of the bus cable body 3 from top to bottom. The flexible heat-conducting plate 103 is covered and fixed on the inner bottom surface of the shielding shell 102, and the bottom surface of the flexible heat-conducting plate 103 is in close contact with the outer upper part of the bus cable body 3. Multiple diffusers are fixed on the outer top surface of the shielding shell 102. The heat dissipation fins 101 are arranged vertically along the horizontal direction, and multiple heat dissipation fins 101 are spaced apart in the vertical direction. The purpose of this arrangement is to provide electromagnetic interference shielding protection for the bus cable body 3 by covering it with the shielding shell 102 of the interference shielding component 1. At the same time, the inner top surface and outer top surface of the shielding shell 102 are respectively covered and fixed with a flexible heat-conducting plate 103 and spaced heat dissipation fins 101. In this way, the heat of the bus cable body 3 can be conducted to the heat dissipation fins 101 through the flexible heat-conducting plate 103 and the shielding shell 102 by contacting the outside of the flexible heat-conducting plate 103 with the outside of the bus cable body 3. This enriches the function of the interference shielding component 1 and realizes efficient heat dissipation while shielding and protecting the bus cable body 3.
[0034] See Figures 1-5 As shown, corner fixing components 2 are provided at each of the four corners of the interference shielding component 1. These corner fixing components 2 are used to quickly assemble and fix the interference shielding component 1 to the outside of the bus cable body 3. Specifically, each corner fixing component 2 includes an insulating card holder 201 and a fixing slot 202. There are four insulating card holders 201, which correspond to the four corners of the shielding cover 102. The insulating card holders 201 are all vertically arranged along the longitudinal direction. The end faces of the insulating card holders 201 at the front and rear positions that are opposite to each other are provided with fixing slots 202 along the longitudinal direction, and the tops of the fixing slots 202 are all open. Meanwhile, the corners of the shielding cover 102 along the longitudinal direction are all locked in the corresponding fixing slots 202 in a vertically tight fit. The purpose of this arrangement is that by locking the four corners of the shielding cover 102 in a tight fit with the fixing slots 202, the interference shielding component 1 can be quickly assembled and fixed outside the bus cable body 3. At the same time, only force needs to be applied to separate the four corners of the shielding cover 102 from the fixing slots 202, and the interference shielding component 1 can be quickly disassembled. The assembly and disassembly of the interference shielding component 1 outside the bus cable body 3 is simple and easy to implement.
[0035] See Figures 1-5As shown, the bus cable body 3, interference shielding component 1, and corner fixing component 2 have been optimized as follows. Specifically, for the bus cable component, both the front and rear ends of the bus cable body 3 are electrically connected to bus plugs 301 for plugging into and connecting with corresponding plug-in boards and system boards, so as to meet the usage requirements of plugging into and connecting the bus cable body 3 with the corresponding plug-in boards and system boards using the bus plugs 301. Specifically, for the interference shielding component 1, the shielding shell 102 is a metal shielding shell, the flexible heat-conducting plate 103 is a rectangular strip of thermally conductive silicone plate, and the heat dissipation fins 101 are all rectangular metal sheets, so that the shielding shell 102 has a good shielding effect, the flexible heat-conducting plate 103 has a good heat conduction effect, and the heat dissipation fins 101 have a heat dissipation area that meets the usage requirements. Specifically, regarding the corner fixing component 2, the bottom surface of the insulating card holder 201 is flatly fixed with a connecting pad 203 to elevate and fix it at the installation position. This allows the insulating card holder 201 to be fixed in the corresponding position inside the embedded computer using the connecting pad 203. Preferably, the thickness of the connecting pad 203 can be customized and adjusted according to actual usage needs, and the connecting pad 203 can be fixed to the connecting surface by covering the bottom surface with hot melt adhesive. Optionally, the fixing slots 202 are all blind slots in the longitudinal direction, and the outer ends of the corresponding corners of the shielding cover 102 abut against the inner ends of the corresponding fixing slots 202. This allows the shielding cover 102 to achieve accurate positioning and limiting by the outer ends of the corresponding corners of the shielding cover 102 abutting against the inner ends of the corresponding fixing slots 202 when engaging with the fixing slots 202, facilitating accurate positioning and fixing of the shielding cover 102 in the installation position. Alternatively, the insulating brackets 201 are all elastic rubber seats, and the corresponding corners of the shielding cover 102 are detachably engaged with the corresponding fixing slots 202 by means of tensioning fit. This setting makes it easy to achieve both the pressing and tensioning fit between the four corners of the shielding cover 102 and the fixing slots 202 and the pulling and disengaging of each other by means of the insulating brackets 201. At the same time, the insulating brackets 201 can also achieve good insulation between the shielding cover 102 and the circuit board below.
[0036] Using the above structure, specifically in the application of the bus cable body 3 in embedded computers, the interference shielding component 1 with heat conduction and heat dissipation functions is provided on the outside of the bus cable body 3. This allows the bus cable body 3 to be protected against electromagnetic interference by covering it with the shielding shell 102 of the interference shielding component 1. Simultaneously, the inner and outer top surfaces of the shielding shell 102 are respectively covered and fixed with a flexible heat-conducting plate 103 and spaced-apart heat dissipation fins 101. Through the contact between the flexible heat-conducting plate 103 and the outside of the bus cable body 3, the heat of the bus cable body 3 can be conducted to the heat dissipation fins 101 for heat dissipation via the flexible heat-conducting plate 103 and the shielding shell 102. This enriches the functionality of the interference shielding component 1, achieving efficient heat dissipation while providing shielding protection for the bus cable body 3, which is beneficial for improving the overall working stability of the embedded computer. Furthermore, corner fixing components are provided at all four corners of the interference shielding component 1. 2. By using the four corners of the shielding cover 102 to be tightly fitted into the fixing slots 202, the interference shielding component 1 can be quickly assembled and fixed outside the bus cable body 3. At the same time, only force needs to be applied to separate the four corners of the shielding cover 102 from the fixing slots 202, and the interference shielding component 1 can be quickly removed. The assembly and disassembly of the interference shielding component 1 outside the bus cable body 3 is simple and easy to implement. It is convenient to cover the bus cable body 3 with the interference shielding component 1 for shielding protection and heat dissipation. It is also convenient to remove the interference shielding component 1 for maintenance and inspection of the bus cable body 3. Moreover, since the insulating bracket 201 of the corner fixing component 2 is an elastic rubber bracket, the setting of the insulating bracket 201 can achieve the pressing and tightening fit between the four corners of the shielding cover 102 and the fixing slots 202 and the pulling and disassembling of them. At the same time, the insulating bracket 201 can also achieve good insulation between the shielding cover 102 and the circuit board below.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
