Description

Technical Field

[0001] This utility model relates to the field of shielding cover technology, specifically a shielding cover with a lightweight reinforcement structure around the clearance hole. Background Technology

[0002] A shield is a functional metal housing component used in electronic devices to suppress electromagnetic interference (EMI) and prevent electromagnetic wave leakage or intrusion of external electromagnetic waves. It is widely used in high-frequency electronic devices such as 5G base stations, aerospace instruments, and precision sensors. Its core function is to block the exchange of electromagnetic energy between the internal circuits of the device and the external environment by using the shielding effect of metal materials and the principle of electromagnetic wave reflection and absorption, so as to ensure that electronic components work stably in complex electromagnetic environments. The structure of the shield needs to be designed according to the layout of the internal components of the device. It often includes a main frame, clearance holes for connectors or heat dissipation components, edge connection parts, etc. Some also integrate lightweight hollow areas and reinforcement structures. Therefore, a shield with a lightweight reinforcement structure around the clearance holes is required.

[0003] In order to ensure their lightweight nature, existing protective shields reduce the amount of sturdy materials used, which often leads to a significant reduction in their strength. Utility Model Content

[0004] The purpose of this invention is to provide a shielding cover with a lightweight reinforcement structure around the clearance hole, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shielding cover with a lightweight reinforcement structure around the clearance hole, comprising a shielding cover body,

[0006] Connection holes are provided on the side wall of the shield body;

[0007] And a reinforcing component disposed on the side of the shield body;

[0008] The reinforcement component includes a reinforcement structure disposed on the side of the shield body;

[0009] An auxiliary mechanism is provided on the side of the shielding cover body.

[0010] Preferably, the reinforcement structure includes a reinforcement ring, which is installed on the inner wall of the shield body with a groove. A reinforcement member is fixedly installed on the side wall of the reinforcement ring. A compression spring is fixedly installed at one end of the reinforcement member, and a plug rod is fixedly installed at the other end of the compression spring. An adjustment block is fixedly installed on the side wall of the plug rod.

[0011] Preferably, the side wall diameter of the plug rod is the same as the inner wall diameter of the positioning hole on the shield body, and the side wall of the plug rod is slidably connected to the inner wall of the positioning hole.

[0012] Preferably, the sidewall of the reinforcing ring contacts the inner wall of the groove on the shielding cover body, and the sidewall of the reinforcing member contacts the inner wall of the groove.

[0013] Preferably, there are two plug-in rods, both of which are of equal shape and size, and are symmetrically arranged with respect to the center plane of the reinforcing ring in the left-right direction.

[0014] Preferably, the auxiliary mechanism includes a honeycomb panel, which is fixedly installed on the inner wall of the shielding cover body, and a connector is fixedly installed on the inner wall of the honeycomb panel.

[0015] Preferably, there are four connection holes, all of which are of equal shape and size, and are located at the four corners of the shield body.

[0016] This utility model provides a shielding cover with a lightweight reinforcement structure around the clearance hole. It has the following beneficial effects:

[0017] (1) The present invention allows the operator to install the reinforcing ring according to the required position. First, the adjusting blocks at both ends are pressed, and the adjusting blocks drive the position of the plug rod to move. One end of the plug rod will press one end of the compression spring. Then, the reinforcing ring and the reinforcing part are installed on the inner wall of the groove on the surface of the shield body. Then, the adjusting block is released. Under the action of the compression spring, one end of the plug rod will enter the inner wall of the positioning hole, which improves the stability of the reinforcing ring and the reinforcing part after installation. This solves the problem that existing protective covers reduce the amount of sturdy materials used in order to ensure their lightweight, which often leads to a significant reduction in their strength.

[0018] (2) This utility model achieves a balance between weight reduction and shielding by setting connectors and honeycomb panels on the inner wall of the shield body and using a simple hollow design, thereby reducing vibration and noise caused by sudden changes in local stiffness.
