Description

The invention relates to power supply for aircraft, in particular unmanned aerial vehicles.

The prior art device for the distribution of electricity (US patent No. 5695933 from 08/12/1997), selected as an analogue. The device contains at least three connectors, each of which is connected to the printed circuit board, while the contacts of the connectors are inserted into the holes of the printed circuit board. The connectors are installed on the board, with one connector connected to a voltage source, and the other two to consumers. The electrical connection and branching is carried out using the tracks of the printed circuit board.

The disadvantage of the analogue is the design complexity and the lack of verification of the correct supply of voltage to consumers.

Also known from the prior art is the electrical distribution device of the aircraft (RF patent No. 2122763 of 06.15.1998), also selected as an analogue. The power distribution device comprises a power supply unit and distribution buses. The power supply is carried out via a power wire, and distribution to consumers using a power bus made in the form of a curved metal plate. The power distribution device is made in the form of a base on which the main and emergency buses are mounted, connected to the contacts of flat diodes, which are installed in cooler blocks, tightened together by explosive bolts with ring necks, protecting the diodes from exceeding contact pressure. To normalize the contact pressure on the diodes, amplification is transmitted to them through two-arm springs and a pusher.

The disadvantages of the analogue are: excessive design complexity and the inability to use in aircraft with more stringent requirements for overall and mass characteristics.

Also known in the prior art is an electrical connector (RF patent No. 2806054 of 05.23.1994), closest to the proposed invention and selected as a prototype. The electrical connector comprises a plug and a socket with sockets having through holes for the pins, as well as an additional contact board on the side of the socket shanks, the contact part of the pins being made of dielectric and interacting with the contacts of the additional contact board. This connector allows you to check the docking of electrical contacts.

The disadvantage of the prototype is the complexity of the design and the inability to implement with its help the branching of electric current.

The objective of the invention is to eliminate the above disadvantages, creating a reliable and compact device for connecting and branching electrical circuits, which also allows for troubleshooting in an unmanned aerial vehicle.

The problem is solved due to the fact that the connector-splitter of the electrical circuits of the aircraft contains an electrical connector, a mating part of the electrical connector and a contact closure of the tail parts of the contacts of the electrical connector, while the tail contact switch of the contacts of the electrical connector is made in the form of a flat conductor with holes, with which the tail parts of the contacts of the electrical connector are interconnected, and the counterpart of the electrical connector is connected to at least one and source of DC voltage and at least one consumer.

In the particular case of the execution of the connector-splitter of the electrical circuits of the aircraft as a flat conductor, a printed circuit board is used.

The essence of the invention is illustrated by the following drawings:

figure 1 - one of the embodiments of the connection of the electrical connector with the contactor of the tail parts of the contacts;

figure 2 is one of the options for connecting DC voltage sources and consumers with a connector-splitter of electrical circuits.

Figure 1 marked:

1 - electrical connector;

2 - contactor;

3 - the tail of the contacts of the electrical connector.

The connector-splitter of the electrical circuits of the aircraft consists of an electrical connector 1, a contactor 2 in the form of a flat conductor and a counterpart of the electrical connector 4. The flat conductor is made with holes, while the tail parts of the contacts of the connector 3 are inserted into the holes of the flat conductor and soldered to the flat conductor. Electrical connector 1 may have at least two pins. The electrical connector 1 is connected to the counterpart of the electrical connector 4. The counterpart of the electrical connector 4 can be connected to at least one constant voltage source and at least one consumer. As a connector, easily mating-undocking serial connectors such as SNC, ONC, or others used in a particular aircraft can be used.

The contacts of the electrical connector 1 of the connector-splitter of the electrical circuits of the aircraft can be selected in the form of pins, then the contacts of the connector of the reciprocal part of the electrical connector 4 should be made in the form of sockets. Also, the contacts of the electrical connector 1 in contact with the counterpart of the electrical connector 4 can be selected in the form of sockets, then the contacts of the counterpart of the electrical connector 4 should be in the form of pins. At least two conductors made, for example, in the form of wires, connecting the counterpart of the electrical connector 4 with at least one constant voltage source and at least one consumer are connected to the contacts of the mating part of the electrical connector 4. The total source of constant voltage and consumers can be a number less than or equal to the number of contacts of the electrical connector 1.

The proposed device is used to organize bus power rockets. In this case, the reciprocal part of the electrical connector 4 is connected by wires, for example, to a source of constant voltage 27 V of the carrier - aircraft 6 (or ship), with an on-board source of constant voltage 27 V of the aircraft (on-board battery 7) and with each consumer of electricity (autopilot 8 , electric drive 9, homing 10 and others).

Also, the use of this device allows you to get the same potential on all contacts of the reciprocal part of the electrical connector 4 and component units, which increases the reliability of the units and the reliability of the analysis of telemetry information. The dimensions and weight of the connector-splitter of the electrical circuits of the aircraft are minimal and almost equal to the dimensions and weight of the electrical connector 1 and the reciprocal of the electrical connector 4, because a flat conductor 2 (or a printed circuit board) is worn on the tail of the electrical connector 3. The use of the proposed device increases the reliability at high currents and avoids overheating of the contactor 2 (flat conductor or printed circuit board). In the proposed device can also be used a printed circuit board with the desired pin connection.

Using the proposed device, you can search for malfunctions in the aircraft. Having undocked the connector-splitter of the electrical circuits of the aircraft, it is possible to localize the malfunction or separately connect the corresponding energy consumer. Thus, the use of the proposed device can improve reliability and simplify the technology of assembly and debugging of an aircraft, in particular an unmanned aerial vehicle.

Consider the operation of the connector-splitter of electrical circuits on the example of one of the variants of the device shown in figure 2.

An electrical connector 1 is connected with a contactor 2 located on its rear parts 3 to the counterpart of the electrical connector 4. The counterpart of the electrical connector 4 is connected to voltage sources: a generator 5, an aircraft electrical system 6 and a battery 7, and also with consumers: an autopilot 8 , with an electric drive 9 and a homing 10. Voltage is supplied to the counterpart of the electrical connector 4 from the on-board network of the aircraft 6 and is transmitted to the autopilot 8, the electric drive 9 and to the heads using an electrical splitter e homing 10, and, if necessary, to the altimeter to other users. In the flight of an unmanned aerial vehicle, voltage is supplied to the connector-splitter of electrical circuits from the generator 5 or from the battery 7 and also transmitted to the autopilot 8, electric drive 9 and homing 10. Thus, the connector-splitter of electrical circuits provides a constant voltage of the required value to the autopilot 8, the electric drive 9 and the homing 10 from various voltage sources.

Troubleshooting the aircraft is carried out by disconnecting the connector-splitter of electrical circuits and checking the contacts of the mating part of the connector 4 in accordance with the electrical circuit.

The present invention distributes the supply voltage to the blocks of the aircraft and ensures reliable operation at high currents of consumption, and high temperatures and vibration overloads, and also allows you to check the correct supply of voltage to the blocks of the aircraft.

The presented drawings and description of the device allow, using the existing element base, to manufacture the device in an industrial way, which characterizes the invention as industrially applicable.
