Specific embodiment
It is specifically described technical solution of the present invention with reference to embodiments, present invention discloses a kind of anti-high frequency spokes of 5G epoch
The operatic tunes shielding case for penetrating and being insulated energy in conjunction with shown in Fig. 2-Fig. 5, including by metal shell 1, plastic cement inner casing 3 and is set to the two
Between adhesive 2 constitute double-layer structure.Specifically, described adhesive 2 can be adhesive glue but be not limited to adhesive glue.It is described
The inner wall of the outer wall of plastic cement inner casing 3 and the metal shell 1 is in close contact, and the outer wall of the plastic cement inner casing 3 is attached at the gold
Belong to the full inner wall surface of shell 1.The planform of the plastic cement inner casing 3 can be identical as metal shell, can also be according to actually answering
With needing to be adjusted, to significantly promote the application range of product.Uniquely invariably, need to keep plastic cement inner casing 3
Outer wall is tightly covered in the full surface of inner wall of metal shell 1, to ensure that the shielding case is to belong to double-layer structure.
The metal shell 1 is the cavity for being provided with an opening.Described adhesive 2 when in use, can be only arranged at institute
At the top of the outer wall for stating plastic cement inner casing, or certain thickness is provided with by the adhesive at top, to utilize the characteristic of adhesive
Realize all standing of the contact surface adhesive of metal shell and plastic cement inner casing.The top is open relative to the metal shell 1
For the inner wall of opposite face.Due to certain thickness glue, plastic cement inner casing is pressed into inside of metal outershell with jig, make glue by
Plastic cement inner casing squeezes, and due to the principle of glue constancy of volume, glue can be along plastic cement inner casing lateral wall and inside of metal outershell
Gap between wall extends, so that glue be made to fill up entire gap, forms the shielding case of double-layer structure.It is of course also possible to use
Coated form, wall or the full surface of inner casing outer wall uniformly coat a layer of adhesive inside the shell, equally can achieve the effect.
Surface for anti-interference, the anti-high frequency radiation effect for further increasing shielding case, the metal shell 1 is arranged
There is electroplated layer.The electroplated layer is and is not limited to nickel coating, silver coating or Gold plated Layer.
Present invention further teaches the preparation sides of above-described 5G epoch anti-high frequency radiation and the operatic tunes shielding case of insulation energy
Method includes the following steps,
The preparation of S1, metal shell are prepared by the punching press that impact style carries out metal shell, to molding metal shell surface
The plating of electroplated layer is carried out by electroplating technology.Sheet Metal Forming Technology is a kind of method for metal working, for metal shell of the present invention
Production has higher production efficiency, simultaneously, and low material consumption is applicable to relatively produce in enormous quantities while accomplishing less waste material and nothing
Waste material production makes full use of material.The metal of the metal shell can be common stainless steel or copper, and this is not restricted.
The preparation of S2, plastic cement inner casing are prepared into plastic cement inner casing by injection molding；
Adhesive is coated on the inside top surface of metal shell in S1 by the integration of S3, inside and outside shell, and by the plastic cement inner casing in S2
The inside of S1 metal shell is placed in a manner of slide fit by clamping jig, plastic cement inner casing is pressed in the metal using formed punch
Outer casing inner wall forms the shielding case of double-shell structure.Double-layer structure is relative to existing only only using the exhausted of spray form
Thermosphere can preferably realize whole insulation, practical although structure of the invention is bilayer, compared with prior art, due to bonding
Agent itself also belongs to one layer of structure, and actual effect can achieve the three times of shielding case in the prior art or more, can also play
Better insulation effect.
Certainly still there are many specific embodiments by the present invention, are just not listed one by one herein.It is all using equivalent replacement or
Equivalent transformation and all technical solutions formed, all fall within the scope of protection of present invention.
