Micro darkroom equipment for mobile phone test

Abstract

A dark chamber for the test of cell phones comprises an electromagnetic wave-absorbing shell, an electromagnetic shielding shell, a receiving antenna and a cell phone rotating table. The electromagnetic shielding shell is a square one formed by a strengthened stainless steel plate with the thickness to be 1.5 mm, and the electromagnetic wave-absorbing shell is a shell made of flat wave-absorbing materials. The electromagnetic wave-absorbing shell is arranged around the inside of the electromagnetic shielding shell and provided with an open door in the same position of the electromagnetic wave-absorbing shell for putting the cell phone in. The cell phone rotating table is arranged on the bottom at one end in the electromagnetic wave-absorbing shell, and the top of the cell phone rotating table is on the same plane with the open door through which the cell phone is put on the cell phone rotating table. The receiving antenna is arranged on the side wall at the other end in the electromagnetic wave-absorbing shell, and the installing position of the receiving antenna on the side wall of the electromagnetic wave-absorbing shell is on the same plane with the top of the cell phone rotating table.

Description

technical field [0001] The invention relates to a mobile phone signal testing device, in particular to a mobile phone testing miniature darkroom device. Background technique [0002] In the current mobile phone testing darkroom equipment, the occupied area and cost of the darkroom are very high, transportation and installation are inconvenient, and relocation is even more difficult. Because the darkroom of the traditional mobile phone test darkroom equipment generally adopts an iron shell, it is definitely not easy to relocate due to the heavy weight of the iron shell. And because its darkroom shell is to utilize keel reinforcement frame to form, so can increase the volume and the weight of equipment equally. In addition, the traditional mobile phone test darkroom equipment uses cone sponge absorbing material as the absorbing material in the darkroom, and the cone sponge absorbing material is currently sold at a high price in the market, and it is usually used in traditiona...

Problems solved by technology

[0002] In the current mobile phone testing darkroom equipment, the occupied area and cost of the darkroom are very high, transportation and installation are inconvenient, and relocation is even more difficult

Because the darkroom of the traditional mobile phone test darkroom equipment generally uses an iron shell, it is definitely not easy to move due to the heavy weight of the iron shell

And because the darkroom shell is made of keel steel frame, it will also increase the volume and weight of the equipment

In addition, the traditional mobile phone test darkroom equipment uses cone sponge absorbing material as the absorbing material in the darkroom, and the cone sponge absorbing material is currently sold at a high price in the market, and it is usually used in traditional mobile phone test darkroom equipment. Occupies a large space, which will also increase the volume of the device

Because if the amount of cone sponge absorbing material does not meet certain requirements, the cone sponge absorbing material will not meet the requirements of absorbing signal waves
