Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1 and fig. 2, which are schematic structural diagrams of the housing 1 in the present embodiment, a first cavity 1-5 is disposed in a middle area of an inner surface of the housing 1, and the first cavity 1-5 is used for disposing an electronic information circuit board.

The first cavity 1-5 is formed by surrounding six vertical wall surfaces 1-4, and all the wall surfaces 1-4 are vertically arranged on the inner surface of the shell 1 in a protruding mode. In order to enable the cavities 1-5 to have a good fixing effect on the electronic information circuit board, the area of the whole first cavity 1-5 is slightly smaller than that of the electronic information circuit board, so that the electronic information circuit board can be embedded into the first cavity 1-5, and all the wall surfaces 1-4 have weak elastic force and can expand towards the periphery. In order to realize the expansion purpose, two ends of one wall surface of the first cavity 1-5 are not connected with other wall surfaces 1-4, so that two gaps are formed between the wall surface and the other wall surfaces, and the stress of the wall surfaces 1-4 is released through the gaps, so that the whole first cavity has weak expansion elasticity. A first positioning groove is arranged in the first cavity 1-5 and matched with the positioning bulge on the electronic information circuit board for positioning the electronic information circuit board.

A ring of closed-loop steps 1-3 are arranged around the first cavity 1-5, the steps are vertically arranged on the inner surface of the shell 1, and the steps 1-3 are used for supporting the cover body 2. The space between the step 1-3 and the first cavity 1-5 forms a second cavity 1-6, and the second cavity 1-6 is used for arranging a closed-loop antenna circuit board. The first cavity 1-5 and the second cavity 1-6 are two completely independent cavities in physical structure, so that the antenna circuit board and the electronic information circuit board are completely isolated from a physical space without electromagnetic interference between the two.

The shell of the outer ring of the step 1-3 is also provided with a plurality of through holes, wherein the end part of the axis of the shell is provided with a first positioning through hole 1-1 which is used for being connected with a first positioning column 2-4 on the cover body 2. And the through holes 1-2 are used for sealing connection with the through holes on the cover plate during plastic package at the later stage. And second positioning columns 1-7 are arranged on the back surface of the shell and are also used for positioning the shell in the later plastic packaging process.

As shown in FIG. 3, the overall size of the cover plate 2 is smaller than that of the casing, and the inner wall surface of the cover plate 2 firstly comprises a step 2-1 from the outermost circle, and the step 2-1 is used for covering the step 1-3 on the casing. The cover plate 2 is provided with a circle of closed-loop convex rings 2-2 and a U-shaped convex ring 2-3 with one open end, and the U-shaped convex ring 2-3 is arranged in the closed-loop convex ring 2-2. When the cover body 2 is covered with the shell 1, the U-shaped convex ring 2-3 and the closed-loop convex ring 2-2 correspond to the second cavity of the shell 1, and after the cover is covered, the two convex rings can press the antenna circuit board to place the antenna circuit board for displacement. The first cavity 1-5 on the cover body 1 corresponds to the U-shaped cavity 2-5 formed by the U-shaped convex ring 2-3 on the cover body 2 after the cover is closed, and the electronic information circuit board and the antenna circuit board can be completely isolated by the structural arrangement. One end of the U-shaped convex ring 2-3 is provided with an opening, so that the electronic information circuit board is conveniently communicated with the antenna circuit board by using a signal wire.

After the cover plate 2 and the shell 1 are closed, the whole shell forms an inner sealed space.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
