Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a card edge connector and a PCB board using the same. Background Technology

[0002] Card edge connectors are common connectors used between circuit board cards, such as PCI connectors and PCI-E connectors (also known as PCIe connectors). These connectors can be used in I / O cards in desktop PCs, as well as in data communication applications in servers, workstations, routers, industrial embedded systems, interface processing and data storage devices (such as graphics cards, hard disk drives (HDDs) and solid-state drives (SSDs)).

[0003] Currently, the market offers high-end, heavy-duty graphics cards with relatively large dimensions. These cards feature a locking mechanism at the rear of the slot, where the locking device automatically rotates to secure the card when it is soldered to the PCB motherboard and the graphics card is inserted. Removing the card requires manually prying open the locking mechanism, but the large size of heavy-duty graphics cards often obstructs the locking mechanism, making this process inconvenient. Therefore, this invention proposes a card edge connector to at least partially address the problems inherent in the existing technology. Utility Model Content

[0004] In view of the above problems, the present invention provides an embodiment of the present invention to provide a card edge connector that overcomes or at least partially solves the above problems.

[0005] To address the aforementioned problems, this utility model discloses a card edge connector, comprising:

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 6 The diagram illustrates a card edge connector of this utility model, comprising: a PCI-E terminal 100, the lower end of which is provided with a PIN pin for electrical connection to a PCB board 400, and an extension end 200 on one side; the extension end 200 is provided with a mounting hole; an ear clip assembly 300, the lower end of which is provided with a rotating shaft 304, and one side of its upper end is provided with a pressing end 302, the rotating shaft 304 being disposed in the mounting hole; the ear clip assembly 300 is provided with a top clip portion 305 of a preset height facing the PCI-E terminal 100.

[0029] In this embodiment, traditional ear clips are located at the rear of the graphics card slot, which are easily obstructed by large, heavily loaded graphics cards. The ear clip assembly 300 in this application is mounted on the extension end 200 on one side of the PCI-E terminal 100 via a rotating shaft 304, changing the position of the ear clip. A pressing end 302 is provided at the upper end of the ear clip assembly 300, allowing the user to operate the pressing end 302 from the side when needing to remove the graphics card, thereby removing the graphics card from the PCI-E terminal 100. This avoids the problem of inconvenience caused by the large size of heavy-load graphics cards obstructing the traditional rear ear clips.

[0030] The new ear clip assembly 300's position and structural design allow users to easily access the pressing end 302 for card ejection, eliminating the need for the previously laborious process of prying open the ear clip from the obstructed rear end. This significantly improves the convenience of card ejection, especially in scenarios requiring frequent insertion and removal of heavy-duty graphics cards, thus substantially increasing work efficiency. The improved ease of operation eliminates the need for excessive force or tools to pry open the obstructed ear clip, reducing the risk of damage to the ear clip, graphics card, or PCB motherboard due to improper handling, thereby lowering hardware repair costs and equipment failure rates. The entire card insertion and removal process is also smoother, making both installing and removing heavy-duty graphics cards easier, providing a better experience for users of high-end, heavy-duty graphics cards and enhancing the product's market competitiveness.

[0031] In one embodiment of this application, as Figure 1 and Figure 2As shown, the lower end of the ear clip assembly 300 is provided with a support portion 301, and the rotating shaft 304 is disposed inside the support portion 301; the lower end of the support portion 301 is horizontal; the end of the extension end 200 is provided with a ramp 201. When the display card or the corresponding electronic card device is inserted into the PCI-E terminal 100, the tail of the display card or electronic card presses down on the top card portion 305, causing the ear clip assembly 300 to spring up. The bottom of the support portion 301 contacts the plane of the extension end 200. When the pressing end 302 is pressed, the rotating shaft 304 drives the support portion 301 to rotate and move it toward the ramp 201, thereby causing the top card portion 305 to lift the display card from the PCI-E terminal 100, separating it from the PCI-E terminal 100.

[0032] In one embodiment of this application, as Figures 4 to 5 As shown, the top of the pressing end 302 has a stepped surface. This stepped surface provides a better tactile feel and pressure point for the user. When pressing the ear clip assembly 300, the stepped surface allows the user to apply force more stably, and the fingers can more precisely control the pressure and direction. Compared to ordinary flat pressing ends, this design makes operation more comfortable, especially when the graphics card needs to be plugged and unplugged repeatedly. It effectively reduces finger fatigue, further improves the convenience and accuracy of operation, and enhances the stability and reliability of the entire card edge connector during use.

[0033] In one embodiment of this application, as Figure 5 As shown, the stepped surface is provided with at least a portion of horizontal lines 303, and other textures such as diagonal lines or multiple dot-shaped protrusions can also be provided to increase the surface roughness, thereby increasing the friction when it comes into contact with the finger surface and preventing the hand from slipping when pressing.

[0034] In one embodiment of this application, the pressing end 302 is located on the right side of the ear clip assembly 300. Generally, when a graphics card is inserted into the PCI-E terminal 100 of a computer, its various components are usually located on the left side of the board, with the PCB board on the right side. This allows for sufficient space for operation and avoids the ear clip assembly 300 being affected by the size of the graphics card or other boards.

[0035] In one embodiment of this application, the PCI-E terminal 100 is provided with a metal casing. Since the signal of the graphics card is generally a high-frequency signal, by providing a metal casing on the outside of the PCI-E terminal 100, it is possible to prevent external electromagnetic interference from interfering with the connection between the graphics card and the PCI-E terminal 100, thereby ensuring the stability of the graphics card signal.

[0036] In one embodiment of this application, based on the same concept, a PCB board 400 is also disclosed, such as... Figure 2 and Figure 3As shown, the PCB board 400 is provided with a card edge connector.

[0037] The beneficial effects of this application include that after the graphics card slot is soldered onto the PCB, the bottom of the tail ear clip has sufficient space from the PCB surface, which will not interfere with other components around it, and facilitates the arrangement and layout of motherboard components; in terms of card removal operation, the existing ear clip structure can only be opened by pressing down on the tail of the ear clip, while the new ear clip structure can also be opened and removed by lifting from the front, providing operators with multiple operation methods.

[0038] Insert the ear clip assembly into the mounting hole at the tail end of the main body of the socket. When inserting the graphics card, it is pressed against the top of the ear clip. At the same time, the ear clip is automatically locked by rotating the rotating shaft. To remove the card, press down or lift the ear clip to open it and then take out the graphics card.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
