Description

 The invention can be used in systems using electronic and computer technology, with non-contact energy input of electric energy from other devices into the closed volume of a sealed device for storing and processing information, receiving and transmitting information between them in the microwave range, when developing portable computing devices, monitoring systems and collecting information, non-volatile reprogrammable devices for long-term storage of information, in particular credit cards, individual banks OF DATA and software.

A well-known electronic block containing a cylindrical housing with a central axis, printed circuit boards with radio elements located radially around the central axis, covers, latches of printed circuit boards, mounting harnesses, holders with stops, on each of which adjacent printed circuit boards are fixed in pairs with their ends, the latches of each pairs of printed circuit boards are made in the form of springs, radio-electronic elements are located on the inner sides of each pair of printed circuit boards, and mounting plaits between the pairs of printed circuit boards, holders are installed with the possibility of th contact of their chocks with the respective caps and the spring retainer [1]
Other devices are known in which, in addition to increasing the vibration resistance of the unit, mounting density, ease of use, its protection against corrosion and explosion is also used [2 and 3]
All of them have the inherent disadvantage of the presence of electrical energy inputs and outputs in the form of connectors, contacts, etc., which significantly weaken the protection of the sealed devices from the adverse effects of the external environment, in particular moisture, due to the heterogeneity of the case.

 Known energy input into a sealed chamber containing a detachable magnetic circuit made of two halves, on which the primary and secondary windings of the energy input are located, located on opposite sides of the wall of the casing of the sealed electronic module of another device [4] This device provides some protection for the electronic block due to a uniform closed shell , which does not have additional connectors for introducing energy into the unit.

 The disadvantage of this device is the use of a closed metal casing of the electronic unit in it, which, solving the problem of sealing the hardware, dramatically reduces the energy transfer efficiency and sharply reduces the frequency range in which it is possible to use a device with acceptable values of the energy transfer efficiency due to the creation of a vortex short-circuited coil, which limits the functionality of the device and narrows the scope of its application.

Closest to the proposed device is a card with electronic components containing a base with cells, electronic components installed in cells filled with a viscous shockproof medium and connected to a common board, and a cable for electrical connection with electronic components [5]
The disadvantages of such a device are low performance and reliability, the presence of which is due to poor protection of the elements from external electric fields, which can lead to loss of information and termination of the device; the lack of the possibility of non-contact energy input of information signals with a certain frequency range into blocks from other devices; insufficient sealing of its components; insufficient rigidity of the structure, which may result in damage to the board or elements, including enclosures and crystals of the LSI; low thermal conductivity of the structure, which imposes serious restrictions on the density of the layout of the elements, the requirements for the element base and operating modes of the elements; low efficiency of the use of internal volume, which imposes restrictions on the integrity.

 The aim of the invention is to improve performance and reliability by providing the possibility of simultaneously contactless reception of power signals and information signals with minimal losses and reliable protection of electronic components from external electromagnetic fields.

 The goal is achieved in that the information storage and processing device, made in the form of a module containing a multilayer printed circuit board, on which electronic blocks are mounted connected in a microelectronic circuit, electronic block cells filled with viscous dielectric material, and the cable is equipped with a sealed metal case, including a cover and a bottom with a hole in which an insert of radiolucent material is sealed, a second multilayer board and a metal base placed inside a metal case between the multilayer boards, the cells filled with viscous dielectric material for the electronic blocks of the first board are made in the base on the one hand, and on the other hand, a sample is made for the second board opposite the radio-transparent material insert, on which are mounted flat cables connected to the electronic blocks coils and screen, while the cover and bottom of the case are hermetically connected to each other, and for the passage of the loop through the base, a through hole is made in it, and t kzhe in that the insertion therein of radiotransparent material is formed on the basis of an alumina ceramic lid and the bottom of the case are sealed to the perimeter weld.

 In FIG. 1 shows a device for storing and processing information, a longitudinal section; in FIG. 2 base of the device in plan.

 The information storage and processing device comprises a metal case, including a cover 1 and a bottom 2 with an opening 3, in which an insert 4 of a radio-transparent material, for example, based on alumina ceramic, is hermetically mounted, a first multilayer board 5 on which electronic units 6 are connected, connected to microelectronic circuit, the second multilayer board 7, connected to the board 5 using a flexible multi-core cable 8 and reinforced opposite the insert 4, in which are mounted flat coils 9, providing power and electromagnetic communication with external transceivers, screen 10, which together with the case covers the board 7 on all sides, except for the side opposite the radiolucent insert, designed to form a directed flow of electromagnetic energy acting on the coils located on the board 7, the metal base 11 placed inside the housing in which the cells 12 are made for accommodating the electronic units 6 of the first board 5, filled with a viscous elastic heat-conducting dielectric material rial 13, for example with gel, while on the other side of the base a sample was made for the second board 7, the cover 1 and the bottom 2 of the case are made of metal and hermetically connected around the perimeter, for example, with a weld seam 14, and for the cable 8 to pass through the base 11 to the boards 5 and 7, a through hole 15 is made therein.

 The operation of the device is as follows.

 Energy input and input of information signals to the device is carried out from other devices. The possibility of contactless transmission of power and information signals is carried out thanks to the electromagnetic coupling of the flat coils 9 of the board 7 with other devices through the insert 4. When information signals arrive at the coil windings 9, further communication with the electronic units is carried out using a cable 8. After processing the signals in blocks 6, information through the loop and coils are supplied to other devices.

 High transmission efficiency in a given frequency range is ensured by the structural structure of insert 4, which reduces the effect of eddy and short-circuited current turns, and the presence of a screen 10, which together with the body forms a directed flow of electromagnetic energy acting on the coils. The proposed design makes it possible to simultaneously provide contactless reception of power and information signals with minimal losses and reliable protection of electronic units from the effects of external electromagnetic fields, since due to the presence of a second board with coils located on it for receiving signals, it is possible to reliably shield the first board with electronic blocks with the help of the housing, base and screen, taking into account the mutual placement of structural elements.

 The efficiency of using this design is achieved by the possibility of placing and wiring a large number of elements of integrated circuits and other open-frame elements, high efficiency of using the internal sealed volume; the possibility of providing a highly efficient heat sink from the elements of the device mounted on the board to the external surface of the device, using a metal base with cells filled with heat-conducting viscous material; providing high mechanical characteristics, eliminating damage to the elements and breaks of the internal joints when exposed to significant bending, shock and vibration loads; ensuring high tightness, preventing the influence of the external environment on the structural elements of the device; good protection of the elements of the device from static electricity and external electric fields.

 The use of this device is most relevant for automatic systems, since its use can significantly increase their accuracy and speed.
