Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as Figure 1-Figure 6 The new disc-shaped shielding reed shown includes more than two reed units 1, and the top end of each reed unit 1 is fixedly connected and sealed to the bottom end of a reed unit 1 above it. The reed unit 1 It includes an upper reed 2 made of metal and a lower reed 3 made of metal, and the present invention is described by taking two reed units 1 as an example.

[0018] The upper reed 2 includes a first upper annular plate 4, a first lower annular plate 5 and a first connecting cylinder 6, and the inner diameter and outer diameter of the first upper annular plate 4 are respectively smaller than the first lower annular plate 5 The inner diameter and outer diameter of the first connecting cylinder 6 are in the shape of a truncated cone with a large lower end and a small upper end. The upper end of the first c...

Abstract

The invention discloses a novel dish-shaped shielding reed which comprises two or more reed units, and the reed units comprise an upper reed unit and a lower reed unit. The upper reed unit comprises afirst upper annular plate, a first lower annular plate and a first connecting barrel. An upper end of the first connecting barrel is sealingly connected to an outer edge of the first upper annular plate, and a lower end of the first connecting barrel is sealingly connected to an inner edge of the first lower annular plate. The lower reed unit includes a second upper annular plate, a second lowerannular plate and a second connecting barrel. The first lower annular plate is coaxial with the second upper annular plate, and a lower surface of the first lower annular plate is fixedly connected toan upper surface of the second upper annular plate. The first upper annular plate of each reed unit and the second lower annular plate of an above reed unit are coaxially disposed and sealingly connected. The novel dish-shaped shielding reed has the advantages that no gap is between various parts, no electromagnetic radiation goes out of the novel dish-shaped shielding spring in use, the electromagnetic shielding effect is good, and electromagnetic interference is not generated to other electrical components during use.

Description

technical field [0001] The invention relates to a novel dish-shaped shielding reed, which belongs to the technical field of electromagnetic shielding. Background technique [0002] The problem of electromagnetic interference is an urgent problem faced by communication equipment. In order to solve the problem of electromagnetic interference, the Chinese utility model patent No. ZL2012207257380 discloses a shielding reed. The shielding reed includes an annular metal sheet. A plurality of spring teeth are evenly arranged on the outer edge, and the spring teeth and the annular metal sheet are inclined inwardly by 0-60° with the vertical surface, and part of the electromagnetic radiation is blocked by the spring teeth. Due to the gap between the spring teeth of the shielding reed, the electromagnetic radiation It can still radiate out from the gap between two adjacent spring teeth, its electromagnetic shielding performance is still not good, and it will still generate electromagn...
