Description

 The invention relates to the field of electronics and computer technology and can be used for non-contact energy input of electric energy from another device into the closed volume of the sealed module, transmission and reception of information between them, in the development of portable computing devices, monitoring and data collection systems, banking and medical services , non-volatile reprogrammable devices for long-term storage of information, credit cards, individual data banks and software x funds.

 A known module with electronic components, comprising a base with cells filled with a viscous shockproof medium, electronic components installed in the cells and connected to a common board, and a cable for electrical connection and electronic components (French patent N 2624284, CL G 06 K 19/02 89 ISM issue 117 N1-90).

 This device, having a certain vibration resistance, does not have protection against adverse environmental influences.

 Other devices are known in which, in addition to increasing the vibration resistance of the module, mounting density, ease of use, protection against corrosion and explosion is also used (AS USSR N 1451880, Mcl H 05 K 5/06, 89).

 All of them have a main drawback - the presence of electrical energy inputs and outputs in the form of connectors, contacts, etc., which contact with a sealed enclosure, which significantly weakens the protection of the sealed devices from the adverse effects of the external environment, in particular moisture, due to the heterogeneity of the case.

The closest technical solution to the proposed device is a device for storing and processing information, comprising a metal case, including a cover and a bottom with a hole in which an insert of radiolucent material is sealed, the first multilayer board on which electronic units are connected, connected to a microelectronic circuit, the second a multilayer board connected to the first one using a flexible multicore loop and strengthened opposite the radiotransparent insert, in which flat and formation (transceiver) coils, power coils and a screen, a metal base placed inside the case, while the base has cells for placing the electronic blocks of the first board filled with elastic heat-conducting material, and on the other side of the base a sample is made for the second board, with this cover and the bottom of the case are made of metal and hermetically connected around the perimeter, and for the passage of the cable to the boards at the base there is a through hole (RF patent N 2046397 1995)
The disadvantages of this device are low performance and reliability, the presence of which is due to:
1. The possibility of distortion or loss of information due to the mutual influence of the flows of electric energy acting on the power supply coils and information (transceiver) coils and low shielding action of the structure when protecting electronic units from static electricity and external electric fields.

 2. Insufficient rigidity of the structure and the possibility of violation of the tightness of the housing due to the use of composite heterogeneous housing.

 3. The low thermal conductivity of the structure due to the use of dielectrics in the sealed enclosure, which imposes restrictions on the requirements for the element base and operating modes of the elements.

 4. The low density of electronic blocks on a multilayer board due to the presence of the base walls between the electronic blocks, which imposes restrictions on the integrity.

 The aim of the invention is to improve the performance and reliability of the device.

 This goal is achieved by the fact that in the device for storing and processing information, made in the form of a module containing a first printed circuit board, on which are installed electronic units connected to a microelectronic circuit, information (transceiver) coils and power coils, a second multilayer board, the first a screen, a metal base, an external sealed enclosure in which a base, a loop, and viscous dielectric material are installed, a third multilayer board, an internal supporting metal case, and volts are introduced a swarm screen, while the information (transceiver) coils and the first screen are installed on the second multilayer board, and the power coils and the second screen are installed on the third multilayer board, with the second and third boards placed on opposite sides of the base, and the information coils and power coils electrically connected to the electronic units by means of a loop, moreover, the first board is placed in an internal load-bearing housing, which is installed in the base between the second and third multilayer boards, and the space between the walls of the internal load-bearing housing, the first circuit board and the electronic units is filled with viscous dielectric material, and the external sealed housing is made of all-metal, while through holes are made for the passage of the cable.

 The drawing shows a device for the accumulation and processing of information, side view.

 The information storage and processing device comprises a sealed all-metal casing 1, a metal base 2, which is placed inside the casing 1, a first multilayer printed circuit board 3, on which electronic units 4 are connected, connected to a microelectronic circuit, a second multilayer circuit board 5, in which information (reception transmitting) coils 6, providing electromagnetic communication with external transceivers, and the first screen 7, designed to form a directed flow of electromagnet total energy acting on the coils 6, the third multilayer board 8, in which the power supply coils 9 are installed, which supply power to the device from external devices, and the second screen 10, designed to generate a directed flow of electromagnetic energy acting on the power coils 9, is an internal carrier a metal case 11 in which the first board 3 is installed, a flexible multi-layer cable 12, which electrically connects the information coils 6 and power supply coils 9 to the electronic units 4, while the second board 5 and the third board 8 are placed on opposite sides of the base 2 between the second board 5 and the third board 8, and the space between the walls of the inner supporting body 11, the first board 3 and the electronic units 4 is filled with viscous dielectric material 13, and for the passage of the loop 12 to the boards 3, 5 and 8 through the inner bearing housing 11 and the base 2 therein, through holes 14 and 15 are made.

 The operation of the device is as follows. Energy input and input of information signals to the device is carried out in a non-contact manner from other external devices. The possibility of contactless transmission of power and information signals is due to the electromagnetic coupling of power coils 9 and information coils 6 with other devices. Upon receipt of electromagnetic energy on the windings of the coils 9 and 6, further communication with the electronic units 4 is carried out using the cable 12. After processing the signals in the blocks 4, information through the cable 12 and the coil 6 is fed to other external devices.

 High efficiency of transmission of electromagnetic energy in a given frequency range is ensured by the presence of two screens 7 and 10, which together with base 2 form directed flows of electromagnetic energy acting on coils 9 and 6.

The introduction of new distinctive features in the device allows to provide:
1. High reliability of receiving, processing and transmitting information by eliminating the possibility of the influence of electromagnetic energy flows affecting power supply coils and information coils, as well as due to the high shielding action of the structure when protecting electronic units from static electricity and external electric fields.

 2. High mechanical characteristics, eliminating damage to the elements and breaks of the internal joints when exposed to significant bending, shock and vibration loads.

 3. High tightness of the device, preventing the effects of adverse environmental factors on the structural elements of the device.

 4. Highly efficient heat sink from electronic units.

 5. High density distribution of integrated circuit elements and other elements.

 The use of this device is most promising for automatic systems, because its use allows you to significantly expand their functionality, their application and increase their accuracy and speed.
