Combined shield assembly

Abstract

The invention discloses a combined shield assembly. The combined shield assembly comprises a shield body and a hard framework, wherein the shield body is an elastic shield body with a certain compression amount; the hard framework is a plastic conductor or metal body with certain resilience; and the shield body is clamped on the outer surface of the hard framework. According to the combined shield assembly provided by the invention, the combined shield assembly can ensure the integrity and deformability of the product, greatly improve the product stability and yield, save cost, and reduce environmental pollution.

Problems solved by technology

[0002] Existing shielding products are formed by one-time mold processing, which has extremely poor flexibility; when the shielding structure of the product needs to be slightly changed, the shielding product needs to be remade (it cannot meet the shielding space), that is, the mold needs to be remade or modified (Generally, the mold needs to be re-opened); resulting in a large waste of cost and resources, and also brings considerable trouble to the designer. If the design is not considered carefully in the early stage or there is a deviation in the design calculation, it will bring problems to the subsequent testing and debugging. Trouble, leading to delays in the delivery cycle or a series of problems such as lengthening the development cycle

[0003] Moreover, the production of existing shielding products requires hot-melt molding of the shielding body and the skeleton; the shielding body and the skeleton are bonded with hot-melt adhesive to form a whole, and the minimum temperature needs to be 150 degrees; resulting in the skeleton (plastic extruded product) Deformation or melting occurs after high temperature, the defective rate of the product is extremely high, and the production stability is poor; materials such as hot melt adhesive are wasted, which leads to problems such as rising costs, low output rate, and prolonged delivery cycle.

And the hot melt adhesive will produce a certain amount of waste gas after melting, which will cause environmental deterioration after being discharged into the air
