Technical Field
[0001] This utility model relates to the field of plastic shell technology, specifically to an anti-shielding plastic shell. Background Technology
[0002] Plastic housings are housings made through injection molding. The housing has a cover to form a sealed space. Electronic components are located inside the plastic housing and can be protected by the plastic housing. Traditional plastic housings are simply made of plastic material.
[0003] However, plastic casings cannot shield against external electromagnetic signals, which in turn can affect the electronic components inside the plastic casing, thus impacting their functionality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an anti-shielding plastic shell, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-shielding plastic shell, comprising a box body and a cover body, wherein fixed supports are fixedly connected to the four corners of the inner wall of the box body, and fixed supports are also fixedly connected to the four corners of the inner wall of the cover body, and fixed screws are provided at the four corners of the upper end of the cover body, the fixed screws passing through the cover body and threadedly connected to the fixed supports at the four corners of the inner wall of the box body, and an anti-shielding mechanism is provided inside the box body and the cover body, the anti-shielding mechanism comprising a metal mesh.
[0006] Furthermore, the connecting end faces of the box body and the cover body are provided with slots, the upper and lower slots are staggered, and the metal mesh is staggered at the connecting end of the box body and the cover body.
[0007] Furthermore, the connecting end faces of the upper and lower fixed supports are provided with fixed grooves, and a metal ring is fixedly connected in the fixed groove on the lower fixed support, and the metal ring is matched and inserted into the fixed groove on the upper fixed support.
[0008] Furthermore, the metal mesh has perforations, which are regular hexagonal in shape and evenly spaced.
[0009] Furthermore, the connecting end of the lower fixed support is located at the lower end of the box body connecting end, and the connecting end of the upper fixed support is located at the lower end of the cover body connecting end.
[0010] Furthermore, the upper end face of the fixing screw is flush with the upper end face of the cover, and the fixing screw is an embedded hexagonal type.
[0011] Compared to the aforementioned background technology, the anti-shielding plastic shell provided in this application includes a plastic shell with very mature technology, and a metal mesh as the core component. Its principle relies on the metal mesh located inside the box and the cover to shield against external electromagnetic signals. Furthermore, the metal mesh at the connection between the box and the cover is staggered, which further improves the sealing effect against shielding signals.
[0012] This invention provides an anti-shielding plastic shell. Compared with the prior art, it has the following advantages:
[0013] This anti-shielding plastic shell features a metal mesh fixed inside the box and lid via injection molding. The metal mesh effectively shields against external electromagnetic interference, and the staggered placement of the mesh between the box and lid prevents electromagnetic signal leakage at the seams, thus achieving a more airtight anti-shielding effect.

[0022] 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.
[0023] Please see Figure 1-7 This utility model provides a technical solution: an anti-shielding plastic shell, including a box body 1 and a cover body 2. Fixing supports 4 are fixedly connected to the four corners of the inner wall of the box body 1, and fixing supports 4 are also fixedly connected to the four corners of the inner wall of the cover body 2. Fixing screws 3 are threaded through the four corners of the upper end of the cover body 2 and are threadedly connected to the fixing supports 4 at the four corners of the inner wall of the box body 1. An anti-shielding mechanism, including a metal mesh 6, is provided inside the box body 1 and the cover body 2. The box body 1 and the cover body 2 are mutually matched and connected. Fixing supports 4 are fixed at the four corners of the inner walls of the box body 1 and the cover body 2. Fixing screws 3 are inserted through the upper end of the cover body 2 to connect and fix the box body 1 and the cover body 2. At the same time, an anti-shielding mechanism is set inside the box body 1 and the cover body 2. Specifically, a metal mesh 6 is set inside the box body 1 and the cover body 2 and distributed around the perimeter. This can provide anti-shielding effect from all directions through the box body 1 and the cover body 2, so that the electronic components inside the box body 1 and the cover body 2 will not be affected by external electromagnetic interference.
[0024] like Figure 2 As shown, a slot 5 is provided on the connecting end face of the box body 1 and the cover body 2. The upper and lower slots 5 are staggered, and the metal mesh 6 is also staggered at the connecting end of the box body 1 and the cover body 2. The slots 5 are staggered at the upper and lower ends at the connection between the box body 1 and the cover body 2. The staggered arrangement of the slots 5 can also make the metal mesh 6 connecting the box body 1 and the cover body 2 staggered, thereby preventing electromagnetic interference at the connection between the box body 1 and the cover body 2.
[0025] like Figure 6 As shown, the connecting end faces of the upper and lower fixed supports 4 are provided with fixed grooves 7. A metal ring 8 is fixedly connected in the fixed groove 7 on the lower fixed support 4, and the metal ring 8 is matched and inserted into the fixed groove 7 on the upper fixed support 4. After the fixed supports 4 correspond to each other, the two fixed supports 4 are fixed by the fixed screws 3. The metal ring 8 located between the two fixed supports 4 can avoid electromagnetic interference from the connection gap.
[0026] like Figure 7As shown, the metal mesh 6 has perforations 9, which are regular hexagons with equal spacing. The regular hexagonal perforations 9 on the metal mesh 6 can improve the stability of the metal mesh 6 and can be tightly fitted and fixed to the box body 1 and the cover body 2 during manufacturing, thereby increasing the contact area.
[0027] like Figure 2 As shown, the connecting end of the lower fixed support 4 is located at the lower end of the connecting end of the box body 1, and the connecting end of the upper fixed support 4 is located at the lower end of the connecting end of the cover body 2. Since the fixed supports 4 are correspondingly arranged and the lower fixed support 4 is located at the lower end of the end face of the box body 1, it is convenient to align the fixed supports 4 when placing the cover body 2.
[0028] like Figure 2 As shown, the upper end face of the fixing screw 3 is flush with the upper end face of the cover 2, and the fixing screw 3 is an embedded hexagonal type. The upper end face of the fixing screw 3 is flush with the cover 2 in order to protect the end of the fixing screw 3 through the cover 2, and the embedded hexagonal fixing screw 3 can avoid slippage when rotating and is easy to rotate.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
