Abstract

The utility model relates to an aero lifesaving seat electromotor with shield to prevent the aero lifesaving seat electromotor from radiating outwards. The aero lifesaving seat electromotor with shield comprises two microswitches, two excitation coils, an arrester coil and excitation coil lead-out wires; one end of a capacitor is connected with the lead-out wires of one excitation coil and one microswitch; the other end of the capacitor is earthed; one end of the other capacitor is connected with the lead-out wires of the other excitation coil and the other microswitch; the other end of the other capacitor is earthed. The aero lifesaving seat electromotor with shield has the advantages that: the capacitor is arranged between the excitation coil and the microswitch; one end of the capacitor is earthed; the negative wire of the electromotor wire is earthed, thereby shielding the spark emitted by an electric brush and a commutator caused by the rotation of the electromotor and the spark caused by the on-off of the microswitches, preventing electromagnetism from radiating outwards and reducing the bouncing influence on the aero lifesaving seat by the aero lifesaving seat electromotor.

Description

A kind of aviation lifesaving's seat motor with shielding

Technical field:

The utility model relates to a kind of aviation lifesaving's of preventing seat motor to extraradial a kind of aviation lifesaving's seat motor with shielding.

Prior art

At present, on the motor of the ejection mechanism of aviation lifesaving's seat, the lead-out wire of the magnetizing coil of motor directly and sensitive switch join, when when sensitive switch moves, driving the Lifesaving chair machine operation, the electromagnetic radiation meeting of Lifesaving chair motor causes other electric devices of Lifesaving chair to be subjected to electromagnetic radiation, and cisco unity malfunction is when this launches in the needs lifesaving, can directly influence the time that lifesaving is launched, thus seat is launched can not urgency the time and cause very serious consequence.

Summary of the invention:

The purpose of this utility model provides a kind of aviation lifesaving's seat motor that can prevent motor to extraradial band shielding.Technical solution of the present utility model is, aviation lifesaving's seat motor of band shielding, comprise two sensitive switches, two magnetizing coils, brake coil and magnetizing coil lead-out wires, one end of a capacitor and the lead-out wire of magnetizing coil and fine motion and pass join the other end ground connection of capacitor; One end of another capacitor and the lead-out wire of another magnetizing coil and another fine motion and pass join the other end of this capacitor and ground connection.

The effect that the utility model produced is, between magnetizing coil and sensitive switch, increase capacitor, one end of capacitor and the shell of motor join, the negative wire ground connection of motor lines, thereby masked because the spark that spark that brush that the motor rotation causes and commutator send and sensitive switch cause, prevent electromagnetism to external radiation, reduced the influence that aviation lifesaving's seat motor launches Lifesaving chair.

Embodiment

Aviation lifesaving's seat motor of band shielding, comprise two sensitive switches 1 and 8, two magnetizing coils 4 and 5, brake coil 12 and magnetizing coil lead-out wire 3 and 6, one end of capacitor 2 and the lead-out wire 3 of magnetizing coil 4 and fine motion are also closed 1 and are joined the other end ground connection of capacitor 2; One end of capacitor 7 and the lead-out wire of another magnetizing coil 56 and another fine motion are also closed 8 and are joined, and the other end of capacitor 7 is by support 15 ground connection.

Aviation lifesaving's seat motor prevents that electromagnetism to extraradial formation, seeing Fig. 1 for details.

DC motor 13 during by sensitive switch 1 and 8, capacitor 2 and 7, magnetizing coil lead-out wire 3 and 6, magnetizing coil 4 and 5, brake coil lead-out wire 11, brake coil 12, braking and lead 9,10,14 etc. are formed.

Aviation lifesaving's seat motor has three leads, and wherein, lead 9 and lead 14 are main track, and lead 10 is a negative wire, the negative pole of a termination power of negative wire 10, and the other end is connected with brake coil 12, and with its ground connection.

Main track 14 1 ends connect positive source, and the other end connects magnetizing coil 4 through sensitive switch 1, and the steering direction of motor 13 is controlled by external sensitive switch 1.Connect an end of capacitor 2 between magnetizing coil 4 and sensitive switch 1, the other end of capacitor 2 passes through ground connection; Main track 9 one ends connect positive source, the other end connects magnetizing coil 5 through sensitive switch 8, the steering direction of motor 13 is controlled by external sensitive switch 8, end with capacitor 7 between magnetizing coil 5 and sensitive switch 8 joins, the other end of capacitor 7 is by support 15 ground connection, thereby realize masking because the motor rotation causes the spark that brush and commutator send, prevent that electromagnetism is to external radiation.

Claims (1)

1. aviation lifesaving's seat motor with shielding, comprise sensitive switch (1), sensitive switch (8), magnetizing coil (4) and (5), brake coil (12) and magnetizing coil lead-out wire (6) and (3), it is characterized in that, the lead-out wire (3) of one end of capacitor (2) and magnetizing coil (4) and fine motion and pass (1) join the other end ground connection of capacitor (2); The lead-out wire (6) of one end of capacitor (7) and magnetizing coil (5) and fine motion and pass (8) join the other end ground connection of capacitor (7).
