Description

Technical Field

[0001] This utility model relates to the field of electronic component installation technology, and in particular to a NOR Flash memory board support bracket for adjusting the installation angle. Background Technology

[0002] In today's electronic devices, especially in cutting-edge fields such as communication equipment, industrial control computers, high-reliability embedded systems, and aerospace, NOR Flash memory chips are widely used to store and directly run critical program code and system firmware due to their superior characteristics, such as strong code execution (XIP) capability, fast read speed, high reliability, and non-volatile data storage. These applications typically place extremely stringent requirements on system stability, anti-interference capabilities, and reliability under complex physical environments (such as vibration, shock, and high temperature).

[0003] To house and protect NOR Flash memory chips, they are typically soldered or mounted onto a dedicated printed circuit board (PCB) to form an independent NOR Flash memory card (or module). This memory card then connects electrically and exchanges data with the system motherboard via connectors (such as board-to-board connectors, pin headers, etc.). However, in actual system integration, especially within compact and complex equipment chassis, the connector positions on the motherboard, cable routing, and overall space constraints are often fixed. This means that the ideal installation position and angle of the memory card may not perfectly match the orientation of the motherboard connectors. Forced installation can lead to uneven stress on the connectors, poor contact, or excessive cable bending, introducing signal integrity risks and even causing connector damage or solder joint cracking under long-term vibration, seriously threatening the stable operation of the system. In existing technologies, the fixing methods for such memory cards are mostly rigid installations. The most common method is to use a simple L-shaped metal bracket, using screws to directly lock the memory card to a specific position on the device housing or motherboard.

[0004] The existing technical solutions have the following drawbacks: the fixed connection method makes it impossible to adjust and change the angle of the storage board, which greatly limits the installation position of the storage board. Therefore, a bracket structure that can adjust the installation angle of the storage board is needed to realize the variable angle installation of the storage board. Utility Model Content

[0005] The purpose of this invention is to provide a NOR Flash memory board support bracket with adjustable installation angle to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An adjustable mounting angle NOR Flash memory board support bracket includes a first frame and a second frame. The second frame is located inside the first frame. The bottom inner part of the first frame has a concentric extension edge. The extension edge has evenly spaced threaded holes running vertically through it. The first frame has through holes corresponding to the threaded holes, and the diameter of the through holes is larger than the diameter of the threaded holes. A support rod is fixedly installed at the bottom center of the first frame. The top surface of the support rod is hemispherical. A rubber ring is bonded to the top of the extension edge. The top surface of the rubber ring fits against the bottom surface of the second frame. The rubber ring has clearance holes corresponding to the threaded holes. A mounting plate is fixedly installed at the bottom inner part of the second frame. The mounting plate is used to mount the memory board, and the top of the mounting plate is coated with an insulating coating.

[0007] By adopting the above technical solution, during use, bolts are inserted from the top of each through hole in the second frame, pass through the clearance hole of the rubber ring, and finally lock into the threaded hole. The length of the bolts is adjusted by screwing the bottom end into the threaded hole, thereby changing the tilt angle of the second frame inside the first frame. The rubber ring supports the bottom of the second frame, thus adjusting the angle of the second frame and adjusting the position of the storage plate mounted on the mounting plate. The top of the support rod is fitted with the bottom of the mounting plate, so that the second frame has a fixed center point when tilted, making it easier to adjust the tilt angle.

[0008] In a further embodiment, each bolt is provided with two rings, which are symmetrically distributed about the second square.

[0009] By adopting the above technical solution, since the diameter of the through hole is larger than that of the threaded hole, in order to enable the bolt head to better apply the fastening force to the second square frame, the contact surface between the bolt head and the second square frame is enlarged by means of a ring.

[0010] In a further embodiment, a flexible buffer layer is adhered to the surface of the ring.

[0011] By adopting the above technical solution, the angle adjustment trajectory of the second square frame is avoided from being interfered with by the circular ring.

[0012] In a further embodiment, the top of the mounting plate is provided with a plurality of through-holes, and a sealing ring is fixedly installed in each hole.

[0013] By adopting the above technical solution, the wiring harness is hidden inside the entire device, making the outside of the device look neater, cleaner and more beautiful, and the sealing ring is used to play a certain role in waterproofing.

[0014] In a further embodiment, there is a gap between the outer wall of the second frame and the inner wall of the first frame, a second rubber layer is fixedly installed on the outer wall of the second frame, and a third rubber layer corresponding to the second rubber layer is installed on the inner wall of the first frame.

[0015] In a further embodiment, a cover plate is snapped onto the top of the first frame.

[0016] The above technical solution is used to protect the storage board.

[0017] In summary, this utility model has the following beneficial effects: 1. During use, bolts are inserted through the top of each through hole in the second frame, passing through the clearance holes of the rubber ring and finally locking into the threaded hole. The length of the bolts is adjusted by screwing the bottom end into the threaded hole, thereby changing the tilt angle of the second frame inside the first frame. The rubber ring supports the bottom of the second frame, thus adjusting the angle of the second frame and adjusting the position of the storage plate mounted on the mounting plate. The top of the support rod is fitted with the bottom of the mounting plate, so that the second frame has a fixed center point when tilted, making it easier to adjust the tilt angle.
