Description

Technical Field

[0001] This utility model relates to the field of computer hardware technology, and in particular to a PCI interface cable support device that prevents pins from coming loose. Background Technology

[0002] In computer hardware systems, the stable connection of PCI interface cables directly affects the data transmission performance and operational reliability of the equipment. As the integration level of electronic devices continues to increase, PCI interfaces must withstand multiple tests such as vibration and external tension under complex operating conditions, which places higher demands on the convenience and stability of cable support devices.

[0003] Most existing PCI interface cable support devices employ a step-by-step fixing method. The support device must first be installed and fixed in a predetermined position inside the chassis using screws, clips, etc., completing a series of operations such as positioning and calibration before the subsequent cable fixing process can proceed. During cable fixing, technicians also need to use auxiliary tools such as cable ties and clips to further adjust and tighten the PCI interface cable to ensure correct connection to the PCI slot. This separate fixing process not only increases the complexity and operation time of hardware assembly, reducing production efficiency, but also makes it prone to human error due to multiple steps. Therefore, there is an urgent need for a PCI interface cable support device that prevents pin detachment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PCI interface cable support device that prevents pin detachment, so as to solve the problem that most existing PCI interface cable support devices mentioned in the background art adopt a step-by-step fixing mode, which requires the support device to be installed and fixed in a preset position inside the chassis by means of screws, buckles, etc., and a series of operations such as positioning and calibration can be completed before the subsequent cable fixing process can be carried out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCI interface cable support device for preventing PIN detachment, comprising a fixed frame, three fixed sleeves fixedly provided on the outer wall of the fixed frame, each of the three fixed sleeves being provided with a pressing rod, a pressing plate being fixedly provided on the three pressing rods, a clamping frame being fixedly provided at the bottom of the pressing plate, two connecting grooves provided on the outer wall of the fixed frame, each of the two connecting grooves being provided with a connecting rod, and a lower pressure plate being fixedly provided on the two connecting rods.

[0006] Preferably, each of the two fixed sleeves located on both sides is provided with a first piston plate that is fixedly connected to the pressing rod, and the outer wall of the first piston plate is connected to the inner bottom wall of the fixed sleeve by a first spring.

[0007] Preferably, each of the two connecting grooves is provided with a second piston plate that is fixedly connected to the connecting rod, and the middle fixed sleeve is provided with a second spring, the two ends of which are respectively connected to the outer wall of the pressing rod and the inner wall of the fixed sleeve.

[0008] Preferably, the fixing frame has two connecting channels inside, and both ends of the two connecting channels are respectively connected to the fixing sleeve and the connecting groove.

[0009] Preferably, both the fixing frame and the clamping frame are L-shaped, the vertical part of the clamping frame slides through the horizontal part of the fixing frame, and the horizontal part of the clamping frame is below the horizontal part of the fixing frame.

[0010] Preferably, the bottom wall of the fixing frame, the upper surface of the pressing plate, the upper surface of the horizontal part of the clamping frame, and the bottom wall of the lower pressing plate are all provided with protective pads, and the protective pads are made of rubber and have anti-slip textures on the surface.

[0011] The beneficial effects of this utility model are:

[0012] 1. Through a unique structural design, the support device and motherboard can be quickly clamped and fixed, and the PCI interface cables can be simultaneously squeezed and fixed. The operator only needs to press once to complete the positioning and installation of the motherboard and the device, as well as the stable support of the cables. This avoids the cumbersome process of fixing the support structure to the chassis first and then fixing the cables separately, which is a traditional method. This greatly shortens the assembly time and significantly improves the installation efficiency.

[0013] 2. Utilizing an innovative structural design involving springs, piston plates, and gas connections, the pressing operation is transformed into a linked fixing action. When external force is applied, all components of the device move in tandem, automatically adjusting the main board clamping and wire fixing status; after the external force is removed, the springs return to their original position, achieving synchronous tightening without the need for additional manual adjustment. This intelligent structural design simplifies the operation process. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A PCI interface cable support device for preventing PIN detachment includes a fixed frame 1. Three fixed sleeves 4 are fixedly provided on the outer wall of the fixed frame 1. Each of the three fixed sleeves 4 is provided with a pressing rod 5. A pressing plate 2 is fixedly provided on the three pressing rods 5. A clamping frame 3 is fixedly provided at the bottom of the pressing plate 2. Two connecting grooves 11 are provided on the outer wall of the fixed frame 1. A connecting rod 8 is provided in each of the two connecting grooves 11. A lower pressure plate 6 is fixedly provided on the two connecting rods 8.

[0022] Each of the two fixed sleeves 4 located on both sides is equipped with a first piston plate 9 fixedly connected to the pressing rod 5. The outer wall of the first piston plate 9 is connected to the inner bottom wall of the fixed sleeve 4 by a first spring 10. The elastic potential energy provided by the first spring 10 enables the first piston plate 9 to push upward. Therefore, in the absence of external force intervention, the distance between the pressing plate 2 and the lower pressing plate 6 is the shortest, and the distance between the horizontal part of the clamping frame 3 and the horizontal part of the fixed frame 1 is the shortest.

[0023] Each of the two connecting grooves 11 is equipped with a second piston plate 12 fixedly connected to the connecting rod 8. A second spring 14 is located inside the middle fixing sleeve 4, with its two ends connected to the outer wall of the pressing rod 5 and the inner wall of the fixing sleeve 4, respectively. The first piston plate 9 is slidably and sealed within the fixing sleeve 4, and the second piston plate 12 is slidably and sealed within the connecting groove 11. The second spring 14, in conjunction with two first springs 10, ensures that the pressing plate 2 can only be lowered after strong pressure, moving it away from the lower pressure plate 6 and closer to the horizontal portion of the fixing frame 1.

[0024] The mounting bracket 1 has two connecting channels 13 inside, and both ends of the two connecting channels 13 are connected to the mounting sleeve 4 and the connecting groove 11, respectively. There is gas between the first piston plate 9, the connecting channel 13 and the second piston plate 12.

[0025] Both the fixing frame 1 and the clamping frame 3 are L-shaped. The vertical part of the clamping frame 3 slides through the horizontal part of the fixing frame 1, and the horizontal part of the clamping frame 3 is below the horizontal part of the fixing frame 1. The upper surface of the horizontal part of the clamping frame 3 contacts the bottom wall of the main board, and the bottom wall of the horizontal part of the fixing frame 1 contacts the upper surface of the main board, thereby realizing the connection between the entire device and the main board.

[0026] Protective pads 7 are provided on the bottom wall of the fixing frame 1, the upper surface of the pressing plate 2, the upper surface of the horizontal part of the clamping frame 3, and the bottom wall of the lower pressing plate 6. The protective pads 7 are made of rubber and have anti-slip textures on their surface. The rubber protective pads 7 can prevent damage to the upper and lower surfaces of the motherboard when the entire device is connected to the motherboard, and the anti-slip textures enhance the anti-slip effect and prevent it from detaching from the motherboard.

[0027] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0028] In use, this invention involves pinching the horizontal portion of the fixing frame 1 and the pressing plate 2 with two fingers, then pressing down on the pressing plate 2 with one finger, bringing it closer to the horizontal portion of the fixing frame 1 and away from the lower pressing plate 6. At this time, the two first springs 10 and the second spring 14 are compressed, and the two first piston plates 9 descend within the fixing sleeve 4. Gas then enters the connecting groove 11 through the connecting channel 13, and then pushes the connecting rod 8 through the second piston plate 12. Subsequently, the lower pressing plate 6 rises away from the vertical portion of the fixing frame 1 and further away from the pressing plate 2. The device then moves closer to the main board, with the edge of the main board positioned between the horizontal portion of the fixing frame 1 and the clamping frame 3. Between the horizontal sections, and with the PCI interface cable passing through the device, that is, between the vertical section of the fixing frame 1, the pressing plate 2, and the lower pressing plate 6, the pressing plate 2 is released and no longer pressed down. At this time, the first spring 10 and the second spring 14 are reset, and the gas returns to the connection channel 13 and the fixing sleeve 4. The lower pressing plate 6 descends, and the pressing plate 2 rises. Together with the vertical section of the fixing frame 1 and the pressing plate 2, the PCI interface cable is squeezed and fixed. At this time, the horizontal section of the pressing plate 2 rises, together with the horizontal section of the fixing frame 1, to achieve the clamping and fixing operation of the edge of the motherboard, thereby realizing the fixed clamping and support of the PCI interface cable.
