(54) DEVICE FOR SCREENING THE CASE OF RADIO ELECTRONIC EQUIPMENT

one

The invention relates to the field of radio electronics and can be used in computing and to protect electronic radiation placed in an electronic device from electromagne-5 radiation disrupting its normal operation.

A device for shielding an electronic housing is known, comprising conductive elements mounted on the inner side of the door with shelves for fastening the ends of the contact springs. A conductive p layer is applied on the shelf.

However, in order to maintain the electrical conductivity of the conductive layer, the cabinet is coated with a conductive paint rather than ordinary. However, the electrical conductivity of the conductive paint is small, which reduces the effect of shielding.

It is also known a device for shielding the body of radioelectronic equipment, comprising a conductor - a 25th element fixed on the inner side of the door of the case, and a contact bent spring mounted at one end on the conductive element G23.

However, the known technical solution has the disadvantage that it does not provide a reliable shielding:

The aim of the invention is to improve the reliability of shielding.

This goal is to improve the reliability of shielding. It is ensured by the fact that in a known shielding device comprising a conductive element fixed on the inner side of the housing door and a contact curved spring mounted at one end on the conductive element. The conductive element is made in the form of two plates, the ends of the contact bent spring are made flat, while one of the ends of the contact bent spring is placed between the plates of the conductor of the coupling element with the possibility of fixation relative to one of them, and the other is mounted on the housing door. FIG. 1 shows a device for shielding an electronic housing, in general; Fig. 2 shows a conductive element; in fig. 3 shows a contact spring, FIG. 4 shows a device for shielding an electronic housing.

equipment in another embodiment / in fig. 5, b is the same in another embodiment.

The device for shielding the body of electronic equipment contains mounted on the inner side of the door i a conductive element; The entant 2, made in the form of two plates 4 and 5 installed with each other with a gap on the thickness of the curved contact spring 3, serves to install the curved contact spring 3, the ends of which BYBLyyena flat, on one of them protrude 6, matching slots 7 plate 5; inside the bent contact spring 3 improves the contact of the door 1 with the cabinet frame 8 divided into lobes by cuts 9. The springs 3 contact the frame 8 with their other end 10. The conductive element is attached to the door 1 with its 4 e plate supporting surface 11 ( See Fig. 1). The ends of the plates 4 and 5 before painting the cabinet are closed (see Fig. 2.6), thus protecting the space between the plates 4 and 5 from falling into it.

. The proposed device makes it possible to substantially simplify the process of protecting the conductive layer and thereby

reduce the labor intensity of manufacturing the device, increase the reliability of shielding.
