Leak-tight socket connector of precision high-temperature vibration-resistant device // 2606212
FIELD: electrical engineering.SUBSTANCE: invention relates to radio and electrical engineering and can be used in instrument making, including for electric circuits switching under conditions of high temperatures. Leak-tight socket connector of precision high-temperature vibration-resistant device comprises ceramic plate with leads, leak-tight embedded into plate body, which is coated with insulating layer from glass, metal ring along ceramic plate outer diameter with applied layer of glass, metal ring along ceramic plate outer diameter with applied layer of glass and leads, made in form of pins from corrosion-resistant metal, have linear expansion factor corresponding to that of ceramics with applied layer of glass, leads are grouped along ceramic plate surface in rows with the same height of pins, pins in row are bent towards row with smaller height of pins, pins ends in place of supplied conductors termination have through hole for crimping and laser welding of lead conductors ends on row with smaller height side, and on metal ring along outer diameter shielding housing is tightly installed on compound.EFFECT: invention enables to increase precision instrument leak-tight socket connector thermal and mechanical resistance, eg for thermocouple temperature measuring device.1 cl, 1 dwg

Starting device of backup power supply automatic input with mechanical interlocking // 2408946
FIELD: electricity.SUBSTANCE: starting device of backup power supply automatic input with mechanical interlocking (MI) includes electric contactors (1), (2) and (3), MI (4), (5), (6) and base (8). The device is equipped with additional electric contactors (3), MI (4) and (6) installed in front of electric contactor (1) and between electric contactors (2) and (3) matching unit (MU) (7). MU (7) consists of a lever (L) (13) performed with bended edges (14) and push bars (PB) (15) and (16). L (13) is fixed at the base (8) in the supports (17) with possibility of axial turning. PB (15) and (16) are hinged to bended edges (14) of L (13) on one side. The other end of PB (15) is put on a pin (11) of MI (4) yoke plate (9), and the other end of PB (16) is equipped with a pin (19) that interacts with electric contactor (3) contact system (12).EFFECT: creating of compact starting device of backup power supply automatic input from three independent power sources with reliable mechanical interlocking of any two electric contactors with one switched on.3 dwg

Device of mechanical interlocking of three automatic switches with electric drive // 2408945
FIELD: electricity.SUBSTANCE: invention can be used for electric circuit control in backup power supply input systems, namely for interlocking of three automatic switches that operate in switch on - switch off automatic mode. Device of mechanical interlocking of three automatic switches with electric drive consists of interlocking mechanisms (1, 2, 3) each of which is equipped with control element performed in a form of actuating pin (4) hinged at the retainer (5) and matching device (6) that includes two pairs of yoke plates (7, 8 and 9, 10). Yoke (7) plate is installed at the axis (11), yoke (8 and 9) plate is installed at the axis (12), yoke (10) plate is installed at the axis (13). At the yoke (7) pivot axis (11) there hinged is double-arm lever (14). At the yoke (13) pivot axis (10) there hinged is double-arm lever (15). The lower levers of the yoke plates (7 and 8) are connected between themselves by joint-hinge (16). The lower levers of the yoke plates (9 and 10) are connected between themselves by joint-hinge (17). The upper levers of the yoke plates (8 and 10) and double-arm lever (14) are hinged to actuating pin (4). The upper levers of the yoke plates (7, 9) and double-arm lever (15) are equipped with support (18) that interacts with actuating pin (4).EFFECT: possibility to interlock in backup power supply input systems of three automatic switches that work in switch on - switch off automatic mode from electric drive.2 cl, 5 dwg

Energy distribution block // 2368028
FIELD: electricity.SUBSTANCE: invention relates to leads for distributing electrical energy, with a main opening for the main supply lead and several openings for energy distribution leads. The openings have sockets with clamping screws for fastening wires in the socket. Each block connection comprises a support for contact with the end of the wire. The structure of the block and its insulating casing provides for visual access to the tip of the wire when put into place, before fastening to the block using clamping screws. The entire top of the insulating casing is made from transparent material and has inner projections for calibrating and restricting movement of some of the clamping screws with the aim of preventing falling of these screws into the casing. Even if the screws are completely out of the block or not in contact with the block, they are kept in line with their corresponding sockets and cannot fall into the casing.EFFECT: method of distributing electrical energy which is safe for fingers, at the same time guaranteeing the fitter possibility of making identical and correct connections with several lead-outs or inputs.26 cl, 12 dwg
