Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an ear-locking mechanism for a PCIE connector. Background Technology

[0002] Motherboards for computers, servers, and other devices have multiple connector slots for expanding functionality. Users can insert electronic cards into these connectors to extend the computer's capabilities. PCIe connectors are among the most widely used. PCIe, short for Peripheral Component Interconnect Express, is a high-speed serial point-to-point interconnect standard used in modern computers to connect high-speed external devices. Graphics cards are the most widely used component in PCIe connectors, followed by network cards, memory modules, and other electronic cards.

[0003] To ensure a secure connection between the electronic card and the PCIe connector, the PCIe connector typically has latches to lock and secure the electronic card after insertion. When removing the electronic card, the latches must be pressed to push the card out and release its locking mechanism before it can be pulled out. Because motherboards often have multiple connectors for various electronic cards, and due to the miniaturization and weight reduction of motherboards, the internal space becomes very limited. Therefore, removing the electronic card by pressing the latches in such a confined space becomes difficult, and even if successful, it often requires multiple attempts, a time-consuming process that causes significant inconvenience to the user. Furthermore, the rigid contact during the latch ejection process can cause wear and tear on the latches themselves. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a latch unlocking mechanism for a PCIe connector, which enables quick removal of electronic cards without pressing the latch, making operation convenient and preventing wear on the latch.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a PCIE connector ear-clip unlocking mechanism, comprising an insulating body, terminals, and ear clips. The insulating body has a slot, and the terminals are disposed within the insulating body and distributed on both sides of the slot along the extension direction of the slot. The ear clips are rotatably disposed at one end of the insulating body. The mechanism also includes a spring piece fixedly disposed at one end of the insulating body and located at the bottom end of the ear clip. The spring piece includes a base plate and an elastic support arm disposed at one end of the base plate. When an electronic card is inserted into the slot, it causes the ear clip to rotate and press down, thereby pressing against the elastic support arm of the spring piece, causing the elastic support arm to deform and store force, while simultaneously holding and fixing the electronic card. Using one end of the ear clip as a fulcrum, the electronic card is pulled out from the other end of the ear clip. During the pulling process, the elastic support arm that was pressed is elastically released, causing the ear clip to rotate and release the holding of the electronic card.

[0006] Preferably, the ear clip includes a pressing part, a stop part, and a pressing part, wherein the pressing part is located at the bottom end of the pressing part and has a guide groove corresponding to the slot, the stop part is located at the upper end of the guide groove, and the ear clip is rotatably connected to one end of the insulating body through the pressing part.

[0007] Preferably, the bottom end of the pressing part is provided with a groove corresponding to the shape of the spring sheet.

[0008] Preferably, the two sides of the pressing part of the ear clip are provided with pivots, and the insulating body is provided with pivot holes corresponding to the pivots. The ear clip is pivotally connected to the pivot holes through the pressing part pivots.

[0009] Preferably, the surface in which the pressing part of the ear loop contacts the elastic support arm has an inclined structure.

[0010] Preferably, the bottom plate of the spring sheet has several contact feet extending from both sides, and the insulating body has a slot corresponding to the contact feet. The spring sheet is fixed by being engaged with the slot by the contact feet.

[0011] The beneficial effects of this utility model are as follows: By providing a spring at the lower end of the ear clip, the elastic support arm of the spring provides an upward elastic force. When the electronic card is inserted into the slot, the ear clip is pressed down and held in place by the ear clip. At the same time, when the electronic card is inserted, the ear clip rotates and presses down, pressing down the elastic support arm to store force. When the ear clip is fixed at one end as a fulcrum, during the process of pulling out the electronic card from the end away from the ear clip, the elastic support arm releases its elasticity and acts on the pressing part of the ear clip, causing the ear clip to rotate and release the holding of the electronic card. This realizes the automatic unlocking of the ear clip and the quick removal of the electronic card, avoiding the inconvenience of removing the electronic card due to the limited internal space of the host or server motherboard. At the same time, during the removal process, there is no direct rigid contact between the ear clip and the electronic card, effectively avoiding contact wear between the electronic card and the ear clip.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] This utility model discloses a latch unlocking mechanism for a PCIe connector, which has a wide range of applications and can be used to connect common hardware such as graphics cards, memory, and network cards to expand the functionality of the computer. In this embodiment, all externally accessible hardware is collectively referred to as electronic card 100 for the purpose of describing this embodiment.

[0031] Please see Figure 1-4 As shown, this embodiment discloses a latch unlocking mechanism for a PCIE connector, including an insulating body 1, a terminal 2, and a latch 3.

[0032] The insulating body 1 is provided with a slot 11, and the terminals 2 are disposed inside the insulating body 1 and distributed on both sides of the slot 11 along the extension direction of the slot 11. Specifically, the insulating body 1 is provided with a fixing hole 12 corresponding to the terminal 2, and the terminal 2 is inserted into the fixing hole 12 for fixing. The bottom end of the terminal 2 extends beyond the bottom end of the insulating body 1 for electrical connection with the motherboard of a computer or server. The terminal 2 located inside the insulating body 1 extends into the slot 11. When the electronic card 100 is inserted, it contacts the electronic card 100 to achieve electrical connection for data signal transmission. In addition, grounding plates 5 are provided on both sides of the insulating body, and the grounding plates contact the terminal 2 in the terminal 2 used for grounding.

[0033] In this embodiment, the ear clip 3 is rotatably disposed at one end of the insulating body 1. Specifically, when the electronic card 100 is inserted into the slot 11, the ear clip 3 rotates under the downward pressure of the electronic card 100 to finally hold the electronic card 100. In order to realize the quick and convenient removal of the electronic card 100, a spring piece 4 is also provided. The spring piece 4 includes a base plate 41 and an elastic support arm 42 disposed at one end of the base plate 41. The spring piece 4 is fixedly disposed at the bottom end of the ear clip 3. As a preferred embodiment, a plurality of contact feet 43 are extended on both sides of the base plate 41 in the spring piece 4. The insulating body 1 is provided with a slot 13 corresponding to the contact feet 43. The spring piece 4 is fixedly engaged in the slot 13 by the contact feet 43 to ensure that the spring piece 4 can be stably disposed on the insulating body 1.

[0034] The ear clip 3 includes a pressing part 31, a stop part 32, and a pressing part 33. The pressing part 33 is located at the bottom of the pressing part 31. The pressing part 31 is provided with a guide groove 34 corresponding to the slot 11. The stop part 32 is located at the upper end of the guide groove 34. Pivots 331 are provided on both sides of the pressing part 33. The insulating body 1 is provided with a pivot hole (not shown in the figure) corresponding to the pivot 331. The ear clip 3 is pivotally connected to the pivot hole through the pressing part 33 pivot 331 to realize the rotation of the ear clip 3 around the pivot 331.

[0035] Please see Figure 5-6 As shown, when the electronic card 100 is inserted into the slot 11, the part of the electronic card 100 located on the side of the ear clip 3 can be inserted along the guide groove 34, ensuring accurate insertion of the electronic card 100. At the same time, the electronic card 100 will press against the surface of the pressing part 33 of the ear clip 3 during the insertion process, and the pressing part 33 will rotate downward under force. When the electronic card 100 is fully inserted into the slot 11, the stop part 32 located at the upper end of the guide groove 34 is above the electronic card 100, thereby realizing the holding of the electronic card 100.

[0036] During the rotation of the pressing part 33 under force, it presses against the elastic support arm 42 of the spring piece 4, causing the elastic support arm 42 to deform and store force. When the electronic card 100 is pulled out, the electronic card 100 is pulled out from the other end of the ear clip 3 with one end as the fulcrum. During the pulling process, the elastic support arm 42 that was pressed is released elastically. Under the action of the elastic force, the ear clip 3 rotates in the opposite direction, causing the stop part 32 to move away from the electronic card 100, thereby releasing the hold on the electronic card 100. This realizes the automatic unlocking of the ear clip 3 and the rapid removal of the electronic card 100.

[0037] As a preferred embodiment, the bottom end of the pressing part 33 in the ear clip 3 is provided with a groove 332 corresponding to the shape of the spring piece 4. The elastic support arm 42 is placed in the groove 332 at the bottom end of the pressing part 33, which can provide a good guiding effect and ensure that the elastic support arm 42 remains stable during the insertion and removal of the electronic card 100, thereby improving the success rate of quickly removing the electronic card 100.

[0038] In a preferred embodiment, the surface where the pressing part 33 of the ear clip 3 contacts the elastic support arm 42 is a sloping structure. Since the pressing part 33 directly applies pressure to the elastic support arm 42, the sloping structure of the contact can ensure a smooth transition between the pressing part 33 and the elastic support arm 42 during the force application process, ensuring stability during the force application process and avoiding wear and tear on the elastic support arm 42.

[0039] The following describes the embodiment in further detail through two methods of removing the electronic card 100.

[0040] I. Conventional Pull-out Method

[0041] Please see Figure 7-8 As shown, the electronic card 100 is removed in a conventional manner by pressing the pressing part 31 of the ear clip 3, causing the ear clip 3 to move along... Figure 7 The central arrow rotates, causing the stop part 32 of the ear clip 3 to gradually move away from the electronic card 100 during the rotation of the ear clip 3. At the same time, the pressing part 33 of the ear clip 3 pushes out the electronic card 100 under the action of rotation; at the same time, the elastic support arm 42 releases its elastic force to the position of the initial shape.

[0042] Please see Figure 9-10 As shown, when the ear clip 3 is rotated to its limit position, the stop part 32 is completely away from the electronic card 100, at which point the electronic card 100 can be pulled out.

[0043] Using the conventional removal method requires manually pressing the ear clip 3 in the confined space inside the host or server, which is inefficient. Furthermore, the ear clip 3 will push out the electronic card 100 during the pressing and rotating process, which will cause wear and tear on the ear clip 3.

[0044] II. Quick Pull-out Method

[0045] Please see Figure 11-12As shown, the method for quickly removing the electronic card 100 is to use one end of the ear loop 3 as a fulcrum and pull the electronic card 100 along the other end of the ear loop 3. Figure 11 As the arrow trails out, the pressing part 33 gradually lifts during the pulling process, and the elastic support arm 42 that was pressed is released elastically. Under the action of the elastic force, the ear buckle 3 rotates in the opposite direction, causing the stop part 32 to gradually move away from the electronic card 100.

[0046] Please see Figure 13-14 As shown, when the ear clip 3 is rotated to its limit position and the stop part 32 is completely away from the electronic card 100, the electronic card 100 can be pulled out.

[0047] The process of removing the electronic card 100 does not require pressing the ear clip 3, thus achieving automatic unlocking of the ear clip 3 and quick removal of the electronic card 100.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
