Description

[Technical Field]

[0001] This utility model relates to the technical field of tinplate shielding shells for high-frequency video cables, and in particular to a single-sided interlocking tinplate shielding cover. [Background Technology]

[0002] Most existing tinplate shielding covers are made of iron or stainless steel. Their high mold-making costs, poor sealing, and low load-bearing capacity limit their use and make them incomparable to zinc alloy tinplate. In recent years, some zinc alloy tinplate covers have adopted a top and bottom cover design, but the top and bottom covers are two different structures, and the mold-making and product costs are still high, and the assembly efficiency is low. [Utility Model Content]

[0003] To overcome the above problems, this utility model proposes a single-sided interlocking tinplate shielding cover that can effectively solve the above problems.

[0004] The present invention provides a technical solution to the above-mentioned technical problems by providing a single-sided interlocking tinplate shielding cover, comprising two identical face covers that interlock with each other and are locked together by screws; the inner side of each face cover is provided with matching interlocking holes and interlocking posts, and the interlocking posts of the two identical face covers are respectively inserted into the interlocking holes of the other; the inner side of each face cover is provided with matching screw fixing grooves and screw holes, and the screw holes of the two identical face covers are respectively fixed to the screw fixing grooves of the other.

[0005] Preferably, a receiving groove is provided on the outer periphery of the screw hole, the receiving groove being used to receive the screw head.

[0006] Preferably, the cover is made of zinc alloy by die casting.

[0007] Preferably, the surface of the cover is polished and then plated with conductive nickel.

[0008] Preferably, the fastening hole and fastening post are located on the upper part of the cover, and the screw fixing groove and screw hole are located on the lower part of the cover.

[0009] Compared with the prior art, the single-sided interlocking tinplate shielding cover of this utility model is designed with the upper and lower covers as a single piece structure, which can be quickly assembled without distinguishing between the upper and lower covers, which helps to improve assembly efficiency. It is also designed with screws to fix the upper and lower covers tightly, achieving the high-requirement shielding and fixing effect and reducing costs. [Attached Image Description]

Detailed Implementation Methods

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0014] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0015] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0016] Please see Figures 1 to 3 The single-sided interlocking tinplate shield of this utility model is mainly used for EMI treatment in high-speed signal transmission. It includes two identical face covers 10, which interlock with each other and are locked together by screws 20. The two identical face covers 10 enclose the product, effectively shielding signal noise and providing a very tight EMI anti-interference effect and internal structural support.

[0017] The inner side of the cover 10 is provided with matching fastening holes 11 and fastening posts 12. The fastening posts 12 of the two identical cover 10s are respectively inserted into the fastening holes 11 of each other, which can effectively position and assemble the parts, improving efficiency.

[0018] The inner side of the cover 10 is provided with matching screw fixing grooves 13 and screw holes 14. The screw holes 14 of the two identical cover 10 are respectively fixed with screws 20 into the screw fixing grooves 13 of each other, making the locking tighter.

[0019] A receiving groove 15 is provided on the outer periphery of the screw hole 14. The receiving groove 15 is used to receive the screw head of the screw 20 so that it does not protrude from the cover 10.

[0020] The face cover 10 is made of zinc alloy die casting. The two face covers 10 are designed with the same single piece assembly interlocking method to achieve low cost, simple structure, convenient assembly, high strength locking shielding fit, plus double-sided screw fixation, making the shielding more secure and the EMI shielding effect better.

[0021] The surface of the cover 10 is polished and then plated with conductive nickel. The zinc alloy shell has a one-piece structure design for both upper and lower flat sections, which is die-cast, polished, nickel-plated, and hardened with conductive nickel plating. It is seamlessly assembled and locked, which enhances the overall support and makes it suitable for shielding, waterproofing, and pressure bearing requirements.

[0022] The fastening hole 11 and fastening post 12 are located above the cover 10, and the screw fixing groove 13 and screw hole 14 are located below the cover 10. The assembly method adopts the upper rivet point for fastening and the lower screw for interlocking. The simple assembly method achieves a good tinplate shielding effect.

[0023] Compared with the prior art, the single-sided interlocking tinplate shielding cover of this utility model is designed with the upper and lower covers as a single piece structure, which can be quickly assembled without distinguishing between the upper and lower covers, which helps to improve assembly efficiency. It is also designed with screws to fix the upper and lower covers tightly, achieving the high-requirement shielding and fixing effect and reducing costs.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any modifications, equivalent substitutions and improvements made within the concept of the present utility model should be included within the patent protection scope of the present utility model.
