Abstract
The utility model discloses an anti-electromagnetic radiation device arranged at the installation part of computer case power. A power assembling port is arranged on the metal backboard of the computer case, and a power supplying device is fixedly arranged at the medial side of the power assembling port. The device is characterized in that: zigzag elastic sheets are installed with intervals at the periphery of the power assembling port, and contacts convex laterally are arranged on the elastic sheets. The contacts are withstood against the metal shell of the power supplying device. The utility model can ensure that the metal backboard of the computer case tightly contacts the metal shell of the power supplying device, therefore effectively preventing the leakage of electromagnetic radiation from injuring human body.
Description
(1) technical field
The utility model relates to the anti-electromagnetic radiation device on a kind of computer housing.
(2) background technology
Along with computer product is come into huge numbers of families, people are more and more higher to the quality requirements of computer product.Particularly office computer, household PC are more and more universal, people usually every day all will be in front of computer slow-witted on several hrs, therefore, prevent that the electromagnetic radiation of computer built-in system from causing the injury to human body to become an important research project.
Existing computer power source supply device generally is mounted in cabinet backboard place, is provided with a power supply installation opening on the metal backing of cabinet, power supply unit with screw retention at power supply installation opening place.Because it is not tight that the metal shell of power supply installation opening and power supply contacts, and just might cause electromagnetic exposure.
(3) summary of the invention
The purpose of this utility model is to provide the anti-electromagnetic radiation device of a kind of computer housing power supply installation position, can prevent effectively that electromagnetic radiation from causing the injury to human body, improves the quality of computer product.
In order to achieve the above object, the utility model provides the anti-electromagnetic radiation device of a kind of computer housing power supply installation position, be on the metal backing of cabinet, to be provided with a power supply installation opening, set firmly power supply unit in power supply installation opening inboard, it is characterized in that: the periphery of this power supply installation opening is interval with the serrate shell fragment, being provided with the contact of protruding to the inside in this shell fragment, conflicts on the metal shell of power supply unit in this contact.
The utility model has the advantages that, the metal backing that can guarantee cabinet closely contacts with the metal shell of power supply unit, realize well, all electromagnetism wave amplitudes are penetrated the source all be enclosed in the metal chassis, can prevent from effectively that electromagnetic radiation from revealing human body is damaged the shielding electromagnetic waves effect.
(4) description of drawings
Fig. 1 is the schematic perspective view of cabinet metal backing of the present utility model.
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
(5) embodiment
With reference to Fig. 1,2, the anti-electromagnetic radiation device of computer housing power supply of the present utility model installation position, be on the metal backing 2 of cabinet, to be provided with a power supply installation opening 4, set firmly power supply unit (figure does not show) in power supply installation opening 4 inboards, the periphery of this power supply installation opening 4 is interval with serrate shell fragment 1, be provided with the contact 3 of protruding to the inside in this shell fragment 1, shell fragment 1 is set as serrate can guarantee that shell fragment 1 has better elastic, makes this contact 3 tightly conflict on the metal shell of power supply unit.
The utility model is conflicted on the metal shell of power supply unit by this contact 3, the metal backing that can guarantee cabinet closely contacts with the metal shell of power supply unit, realize good shielding action to electromagnetic radiation, all electromagnetism wave amplitudes are penetrated the source all be enclosed in the metal chassis, can prevent effectively that the electromagnetic radiation leakage from damaging human body.
Be to be understood that; though the utility model is described the foregoing description; but be not limited to described specific embodiment, possible modification and the change done on principle of the present utility model and spiritual basis must belong within the protection domain of the present utility model.
Claims (1)
