The structure of the computer keyboard consists of a keyboard shell, keys, a circuit board and a keyboard cable, wherein the keyboard shell consists of an upper cover and a base; the circuit board is arranged between the upper cover and the base; an elastic waterproof film is covered on the upper surface of the upper cover, a conductive plated film is attached to the lower surface of the elastic waterproof film, and the conductive plated film is attached to the outer surface or the inner surface of the base; a seam for connecting the upper cover and the base is provided with a conductive gland strip, and the conductive plated film and the conductive gland strip are connected with an earth wire on the circuit board through conducting wires; each key consists of a key column and a key cap; the lower end of the key column is connected with a key contact on the circuit board, and the upper end of the key column passes through the upper cover to connect with a corrugated sleeve; and a concave hole at the bottom of the key cap is buckled on the top of the corrugated sleeve, and the edge part of the corrugated sleeve is connected with the elastic waterproof film and attached with the conductive plated film. Compared with the prior art, the computer keyboard has the functions of water prevention, dust prevention, radiation prevention and the like, has good confidentiality, and can effectively prolong the service life of the keyboard; therefore, the computer keyboard has good popularization and usage value.
Description
Technical field
The present invention relates to a kind of keyboard, three anti-keyboards of specifically a kind of waterproof and dustproof and anti-electromagnetic radiation.
Background technology
Computing machine is commonly used in the supplemental treatment of hospital and diagnosis, but the particular surroundings of common computer keyboard incompatibility hospital, such as the water logging accident of laboratory with computing machine, because of be immersed in water the fully probability that causes computer motherboard to be burnt of keyboard very little, it is that reason is that water tumbler knocks over or the water tumbler spilling water spreads keyboard and causes short circuit that accident takes place maximum, at present the document of waterproff keyboard is a lot, is mostly to be provided with drainage system or the keyboard wiring board sealed to prevent the keyboard circuit short circuit on keyboard.
Also have the various radiation of radiation chamber heavy dose that keyboard is also had very big influence, be easy to cause losing or mistake of data, in addition, also have the button of keyboard impacting process, on-off circuit in the keyboard circuit on the keyboard can send a certain amount of electromagnetic radiation in handoff procedure, equally also can influence the normal operation of Medical Devices.Different button electromagnetic radiation two also different, use the special electromagnetic radiation detecting instrument will detect the signal that impacts keyboard according to different amount of electromagnetic radiation, by analyzing the interior perhaps information of keyboard operation of then decoding, if this keyboard is used on the secure computer, the danger of divulging a secret is very serious, and the three anti-keyboards of maintaining secrecy with waterproof and dustproof and anti-electromagnetic radiation are not also arranged at present.
Summary of the invention
The invention provides a kind of waterproof, protection against the tide, dustproof, electrostatic prevention and radiation-resistant medical three anti-keyboards.
Waterproof of the present invention, dustproof, electrostatic prevention and the radiation-resistant three anti-keyboards of maintaining secrecy are realized in the following manner, the structure of the computer keyboard that this waterproof anti-electromagnetic radiation is divulged a secret is by keyboard case, button, circuit board and keyboard cable, keyboard case is made up of loam cake and base, circuit board is arranged between loam cake and the base, upper surface at loam cake is coated with the elastic water-proof film, lower surface at the elastic water-proof film is attached with the conduction plated film, adhering at the outside surface of base or inside surface has the conduction plated film, be provided with the conductive seal bar between the seam that loam cake and base join, conduction plated film and conductive seal bar are connected with ground wire on the circuit board by lead, button is by the key post, keycap is formed, the lower end of key post is connected with key contacts on the circuit board, the upper end is passed loam cake and is through in the radiation fins and asks, the shrinkage pool of keycap bottom is buckled in the top of radiation fins, and the limit portion of radiation fins and elastic water-proof symphysis connect and also be attached with the conduction plated film.
The invention has the beneficial effects as follows: waterproof, protection against the tide, dustproof, radiation proof, electrostatic prevention, good confidentiality can effectively prolong keyboard serviceable life.
