Description

Technical Field

[0001] The present invention relates to the technical field of the structural design of electronic devices, and particularly to a new blade board card tray. Background Art

[0002] Traditional blade board cards adopt a rigid fixed structure and cannot adapt to the installation inclination problems caused by different circuit board thicknesses (±10% tolerance). Especially in high-speed and high-density scenarios, it is easy to cause a decline in signal quality.

[0003] Such as Figures 4 to 6 In the schematic diagram of the prior art structure of, the blade board card 3 is directly inserted into the guide slot on the side of the guide rail board 2. At the same time, the slot 4 of the bus backplane 1 needs to match the positions of the connectors 5 on the blade board card 3. Therefore, due to error factors, the blade board card 3 will be inclined relative to the guide slot of the guide rail board 2;

[0004] At the same time, the existing solution relies on the copper-exposed area of the circuit board of the blade board card 3 to contact the guide rail board 2 to achieve ESD protection. However, due to processing tolerances or plugging and unplugging vibrations, the contact is poor and the protection effect is unstable.

[0005] Therefore, we propose a new blade board card tray to solve the problems mentioned above. Summary of the Invention

[0011] Preferably, the inner wall of the welding nut sleeve is designed to be smooth, and the welding nut sleeve is slidably connected to the screw rod.

[0012] Preferably, the second nut sleeve is rotated to adjust the relative height with the screw rod, so as to change and adjust the height of the blade board relative to the bus backplane, and the first nut sleeve clamps the blade board on the second nut sleeve.

[0013] Preferably, an embedded nut head is integrally provided at the lower end of the screw rod, and the embedded nut head is embedded in the tray.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figure 1 , the present invention provides a technical solution: a new blade board card tray, including: a tray 6 and a blade board card 3. The tray 6 is detachably installed on the bus backplane 1, and the edge of the tray 6 is inserted into the guiding slot of the guide rail plate 2;

[0030] A number of studs 8 are arranged on the tray 6, welding nut sleeves 10 are arranged at corresponding positions on the blade board card 3, a screw 9 is rotatably arranged in the welding nut sleeve 10, and the screw 9 is threadedly connected with the stud 8. By rotating the screw 9, the distance between the welding nut sleeve 10 and the stud 8 is adjusted, and then the distance between the blade board card 3 and the tray 6 is adjusted;

[0031] By directly inserting the tray 6 into the guiding slot of the guide rail plate 2 and using the screw 9 to pre-adjust the distance between the blade board card 3 and the tray 6, it is ensured that when each blade board card 3 is docked with the bus backplane 1, the relative position of the front surface of the blade board card 3 is fixed, that is, the position of the backplane connector 5 on the front surface of the blade board card 3 relative to the slot 4 is fixed. A number of connectors 5 are installed on the blade board card 3 to accurately dock the connectors 5 with the slots 4 on the bus backplane 1.

[0032] Conductive foams 7 are symmetrically and fixedly installed at the left and right edges of the upper surface of the tray 6, and the conductive foams 7 are in contact with the copper-exposed areas on both sides of the blade board card 3 to further optimize the anti-static interference effect.

[0033] Embodiment 2

[0034] Please refer to Figure 2 and Figure 3, the present invention provides a technical solution: a new blade board card tray, including: a bus backplane 1, a blade board card 3, and a tray 6. The difference between this embodiment and the first embodiment is that at the position of the welding nut sleeve 10 corresponding to the blade board card 3 on the tray 6, a threaded sleeve 18 is provided. A screw rod 15 is installed between the welding nut sleeve 10 and the threaded sleeve 18. The screw rod 15 is threadedly installed with the threaded sleeve 18. The screw rod 15 passes through the welding nut sleeve 10. First nut sleeves 14 and second nut sleeves 16 are threadedly installed on the upper and lower parts of the screw rod 15 located in the welding nut sleeve 10;

[0035] After the screw rod 15 is threadedly fixed to the threaded sleeve 18, first install the second nut sleeve 16 on the screw rod 15, then align the welding nut sleeve 10 of the blade board card 3 with the screw rod 15 and place it in. Here, the inner wall of the welding nut sleeve 10 is designed to be smooth, and the welding nut sleeve 10 is slidably connected to the screw rod 15. Then, put the first nut sleeve 14 on the screw rod 15. By adjusting the height of the second nut sleeve 16 relative to the screw rod 15, the height of the blade board card 3 relative to the bus backplane 1 is adjusted. Then, clamp the blade board card 3 through the first nut sleeve 14, making the height adjustment of the blade board card 3 more flexible.

[0036] An embedded nut head 17 is integrally provided at the lower end of the screw rod 15, and the embedded nut head 17 is embedded in the tray 6 to improve the aesthetics.

[0037] Another difference between this embodiment and the first embodiment is that a horizontal light emitter 12 is inserted into the bus backplane 1, and a light sensor receiver 11 is inserted into the blade board card 3. The light sensor receiver 11 receives the light emitted by the horizontal light emitter 12. A real-time induction indicator light is provided on the light sensor receiver 11. When the light sensor receiver 11 receives the light emitted by the horizontal light emitter 12, the induction light lights up;

[0038] When installing the blade board card 3 and the tray 6, insert the horizontal light emitter 12 into the bus backplane 1 and insert the light sensor receiver 11 on the blade board card 3. During the adjustment of the blade board card 3, by receiving the light of the horizontal light emitter 12 through the light sensor receiver 11, the levelness of the blade board card 3 relative to it is determined to ensure that the height of the blade board card 3 matches the height of the bus backplane 1. After the installation is completed, remove the horizontal light emitter 12 and the light sensor receiver 11.
