Description

The proposed technical solution relates to the design of control and testing equipment used to conduct various types of testing of electronic components requiring the measurement of resistance, current, and voltage in electrical circuits using two- and four-wire circuits, including applying electrical signals to the tested components during functional/parametric testing, multiplying the electrical circuits of the tested components during functional/parametric testing, and any combination of the above applications, as well as during the preparation and conduct of radiation and other types of testing. Depending on the test requirements, the switching and diagnostic device enables switching of a large number of measurement channels. The design of the switching and diagnostic device can be used as an electrical connection device in complex automated control and measurement systems and ensure the electrical interfacing of electronic components with various means for measuring electrical and/or physical parameters under conditions of exposure to ionizing radiation. A radio-electronic unit is known (RU Patent for Utility Model No. 50070, priority 30.06.2005, publication 10.12.2005), comprising a housing, mounting boards with rectangular electrical connectors connected to them at their contact ends, installed parallel to one of the walls of the housing, the mounting boards are connected to each other with their end parts to form a rigid package and are fastened to the housing using fasteners, in which an insulating cover is introduced, closing the housing, in the internal cavity of the insulating cover a backplane is installed, on the surface of which rectangular electrical connectors are placed, connected to rectangular electrical connectors on the contact ends of the mounting boards, in addition, on the outer surface of the insulating cover there is an electrical connector connected to the backplane, wherein two round electrical connectors are connected to the contact end of each mounting board opposite to the end with which the rectangular electrical connector is connected forms placed on the outside of the body and connected to the body using fasteners. A drawback of this device is the inability to use the unit for radiation testing, as the layout of the boards prevents uniformity of the absorbed ionizing radiation dose across each surface, and there is no way to controllably shield part of the structure during radiation resistance testing. This device also lacks the ability to quickly connect and disconnect the circuit boards, and it is not possible to adapt the switching to different types of microcircuits. A universal high-voltage switching unit (Russian Federation patent for utility model No. 189048, priority date October 29, 2018, publication date May 7, 2019) is also known. It consists of a 1U enclosure, fans, and a toggle switch mounted on the front panel, a switch, a service compartment, and upper and lower backplanes, with the backplanes arranged horizontally. Furthermore, the switching unit can accommodate one to three additional switches. High-voltage measurement and digital control signals are routed to separate printed circuit boards. A drawback of this device is the inability to use the unit for radiation testing, as there are no niches for dosimetric instruments and no way to controllably shield part of the structure during radiation resistance testing. This device also does not provide for the placement of test objects directly within the structure on mounting boards, nor does it allow for combining different types of boards. The closest analogue of the proposed technical solution is an electrical equipment unit and a mounting panel (RU Patent for Invention No. 2013895, priority dated December 29, 1991, publication dated May 30, 1994). The described device comprises connectors installed in the unit (described as a housing) for the electrical connection of circuit boards via mating connector parts formed on the ends of the boards. The circuit boards are connected to each other at their ends by paired mounting panels to form a rigid package and are secured to the housing and to each other using fasteners. The mounting panel consists of a rectangular plate with a 90° bend, on which fasteners are provided. Parallel, shaped cutouts are made on the long shelf of the plate, the shape of which is similar to the shape of the outer contours of the electrical connector housings, and the cutouts are made with flanges. The disadvantages of this device include: the impossibility of using the unit for radiation testing, as no niches are provided for dosimetric instruments; the arrangement of the boards does not ensure uniformity of the absorbed dose of ionizing radiation on the surface of each of them; the inability to controllably shield part of the structure during radiation resistance testing. The objective of the proposed technical solution is to expand the functionality and versatility of the device by al
