Technical Field

[0001] This utility model relates to the field of computer motherboard technology, and more specifically, it relates to a computer motherboard with interface expansion. Background Technology

[0002] Computers are increasingly being applied to various fields. However, the functionalities and requirements of computers vary across industries, necessitating customization. The most significant customization lies in the different interface requirements of various industries. Customizing motherboards to meet these diverse interface requirements would significantly increase costs and create problems in subsequent stages such as material preparation, production, sales, and after-sales service.

[0003] Currently, when replacing the interface on computer motherboards on the market, the following technical problems often exist: When existing computer motherboards install and position interfaces in a detachable manner, the connector terminals of the interfaces often lack sealing protection and isolation structures. This makes it easy for external dust and debris to enter the connector terminals, leading to poor contact during later use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a computer motherboard with interface expansion that can seal and protect the connector terminals of the interface component after plugging and fixing, prevent external dust and debris from entering the connector terminals of the interface component, and prevent poor contact in the future.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A computer motherboard with interface expansion includes a motherboard body, on which a plurality of interface components are inserted and fitted, and a cover fitting slidably fitted on the motherboard body; the top of the motherboard body is provided with a plurality of electrical connection sockets that are respectively inserted and fitted with a plurality of interface components; the top of the motherboard body is fixed with symmetrical side plates, and a transverse guide groove is provided through one side of each side plate; the cover fitting includes a movable rail slidably fitted between the two transverse guide grooves, and an L-shaped cover plate is fixed at the bottom of the movable rail; the L-shaped cover plate has a plurality of sealing cover frames adapted to the interface components fixed in a linear array inside.

[0006] The present invention is further configured such that: sliding columns are fixed on both sides of the moving rail; two symmetrical baffles are fixed on the top of the main body of the main board, and pins are fixed on the opposite sides of the two baffles; a lower pressure arm is rotatably engaged on the circumferential side of the pin; and a sliding groove is slidably engaged on the sliding column on one side of the lower pressure arm.

[0007] The present invention is further configured such that: an arc-shaped spring is fixed between the lower pressure arm and the main body of the motherboard; an elastic metal sheet is fixed at the end of the lower pressure arm; and a groove is provided on the top of the elastic metal sheet; two symmetrical U-shaped plates are fixed on the top of the main body of the motherboard; and a circular column that fits into the groove is fixed inside each of the two U-shaped plates.

[0008] The present invention is further configured such that: the top of the main body of the motherboard is fixed with several sets of vertical plates in a linear array between the two side plates, and the number of vertical plates in each set is two.

[0009] The present invention is further configured such that: a number of fixed plates are fixed in a linear array at the top of the main body between the two side plates, and the number of fixed plates in each group is two; a contact rod is slidably fitted through the side of the fixed plate, one end of the contact rod is rounded, and a circular plate is fixed to the other end of the contact rod; an elastic spring is fixed between the circular plate and the fixed plate and fitted on the contact rod.

[0010] The present invention is further configured such that: the interface component includes a wiring port that is plugged into each group of vertical plates, and one side of the wiring port is electrically connected to a plurality of port pins that are plugged into the electrical connector.

[0011] The present invention is further configured such that: two symmetrical J-shaped plates are fixed on the top of the connected port, each of the two J-shaped plates has a plug hole on one side, and the bottom of the two J-shaped plates is rounded, and the two plug holes are respectively plugged into the rounded ends of the two abutment rods.

[0012] The advantages of this utility model are: 1. By pressing down the lowering arm, the sliding groove through one side of the lowering arm slides synchronously on the circumferential side of the sliding column, thereby driving the moving rail to move horizontally inside the two transverse guide grooves. This allows several sealing cover frames fixed in a linear array inside the L-shaped cover plate to slide and fit onto the surfaces of several different types of interface components, thereby sealing and protecting the connector terminals of the interface components after insertion and fixing, preventing external dust and debris from entering the connector terminals and preventing poor contact later.

[0013] 2. This utility model, by pressing down on the top of the wiring port, causes the two abutment rods slidingly fitted on the side of each set of fixing plates to move horizontally away from each other simultaneously. This causes the elastic springs fixed between the circular plate and the fixing plate to stretch slowly until the rounded ends of the two abutment rods coincide and align with the insertion holes. Then, the two abutment rods move closer to each other under the elastic force of the two elastic springs. This achieves a detachable installation and fixing method for the interface component, making it convenient for users to install and replace different types of interface components.

Detailed Implementation

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution: Specifically, it refers to a computer motherboard with interface expansion, including a motherboard body 1, a number of interface components 2 inserted and fitted on the motherboard body 1, and a cover 3 slidably fitted on the motherboard body 1; the top of the motherboard body 1 is provided with a number of electrical connection sockets 101 that are respectively inserted and fitted with a number of interface components 2; the top of the motherboard body 1 is fixed with symmetrical two side plates 102, and a transverse guide groove 103 is opened through one side of each side plate 102; the cover 3 includes a moving rail 301 slidably fitted between the two transverse guide grooves 103, and an L-shaped cover plate 302 is fixed at the bottom of the moving rail 301; the L-shaped cover plate 302 has a number of sealing cover frames 303 adapted to the interface components 2 fixed in a linear array inside; Furthermore, sliding posts 304 are fixed on both opposite sides of the moving rail 301; two symmetrical baffles 104 are fixed on the top of the main body 1, and pins 105 are fixed on opposite sides of the two baffles 104. A lower pressure arm 106 is rotatably fitted on the circumference of the pin 105. A sliding groove 107 is provided on one side of the lower pressure arm 106, which is slidably fitted on the sliding post 304; an arc spring 108 is fixed between the lower pressure arm 106 and the main body 1, and an elastic metal sheet 109 is fixed at the end of the lower pressure arm 106. A groove is provided on the top of the elastic metal sheet 109; two symmetrical U-shaped plates 110 are fixed on the top of the main body 1, and circular posts 111 that fit into the grooves are fixed inside the two U-shaped plates 110.

[0026] The specific application of this embodiment is as follows: After the different types of interface components 2 are detachably installed and fixed, by pressing down the pressing arm 106, the sliding groove 107 through one side of the pressing arm 106 slides synchronously on the circumferential side of the sliding column 304, thereby driving the moving rail 301 to move horizontally inside the two transverse guide grooves 103. This causes the sealing cover frames 303, which are fixed in a linear array inside the L-shaped cover plate 302, to slide and fit onto the surfaces of the different types of interface components 2. When the sealing cover frames 303, which are fixed in a linear array inside the L-shaped cover plate 302, slide and fit onto the surfaces of the different types of interface components 2, their elastic metal sheets 109, under the pressing force, When the relative closing and closing phenomenon occurs, the overall length of the lowering arm 106 and the elastic metal sheet 109 will become relatively shorter. Until the elastic metal sheet 109 and the lowering arm 106 are pressed down to the bottom of the circular column 111, the elastic metal sheet 109 will undergo a mutual expansion and reset process under its own elastic force. Finally, through the mutual contact between the groove set on the top of the elastic metal sheet 109 and the circular column 111, the sliding cover 3 is sealed and locked. This provides sealing protection and isolation for the terminal of the interface component 2 after plugging and fixing, preventing external dust and debris from entering the terminal of the interface component 2, preventing poor contact in the later stage, and improving the stability of the main board body 1.

[0027] Example 2, please refer to Figure 1-7 This second embodiment improves upon the first embodiment as follows: Specifically, several sets of vertical plates 112 are fixed in a linear array at the top of the main body 1 between the two side plates 102, with two vertical plates 112 in each set; several sets of fixing plates 113 are fixed in a linear array at the top of the main body 1 between the two side plates 102, with two fixing plates 113 in each set; a contact rod 114 is slidably fitted through the side of the fixing plate 113, with one end face of the contact rod 114 rounded, and a circular plate 115 is fixed to the opposite end face of the contact rod 114; the circular plate 115 and... An elastic spring 116 is fixed between the fixed plates 113 and sleeved on the abutment rod 114; the interface component 2 includes a wiring port 201 that is inserted between each set of vertical plates 112, and a number of port pins 202 that are inserted into the electrical connector 101 are electrically connected to one side of the wiring port 201; two symmetrical J-shaped plates 203 are fixed to the top of the wiring port 201, and each of the two J-shaped plates 203 has a plug hole 204 on one side. The bottom of the two J-shaped plates 203 is rounded, and the two plug holes 204 are respectively inserted into the rounded ends of the two abutment rods 114.

[0028] A specific application of this embodiment is as follows: During the installation and use of this utility model, different types of interface components 2 are placed inside each set of vertical plates 112 (the types of interface components 2 are RJ45 and USB 2.0 ports, and when the interface component 2 is installed and fixed in a detachable manner, its electrical connection base 101 is reserved with holes for the RJ45 and USB 2.0 port pins 202, supporting RJ45 and USB Type-A dual-mode plug-in communication functions. In the later use, a high-speed electronic switch matrix is ​​set in the main board 1, which is connected to the USB 2.0 controller and the network card chip. Through the impedance automatic detection circuit, the type of the connected interface component 2 is identified, the specific signal function at that location is determined, and the signal is routed to the corresponding interface function. At the same time, the dedicated ASIC chip of the hybrid protocol controller inside the main board 1 realizes the protocol conversion. The USB 2.0 mode supports 480Mbps transmission, and the Ethernet mode supports 10 / 100 / 1000M adaptive function). During the placement process, by pressing down on the top of the wiring port 201, the bottom rounded corners of the two J-shaped plates 203 fixed to the top of the wiring port 201 gradually move closer to each other. The rounded ends of the two contact rods 114 are pressed until the bottom rounded parts of the two J-shaped plates 203 are in contact with the rounded ends of the two contact rods 114. Then, the wiring port 201 is pressed, so that the two contact rods 114 slidingly fitted on the side of each set of fixing plates 113 move horizontally away from each other. This causes the elastic springs 116 fixed between the circular plate 115 and the fixing plate 113 to stretch slowly until the rounded ends of the two contact rods 114 are aligned with the insertion hole 204. Then, the two contact rods 114 move closer to each other under the elastic force of the two elastic springs 116. This achieves the detachable installation and fixing method of the interface component 2, which is convenient for users to install and replace different types of interface components 2.
