The present invention relates to a power supply connector particularly suitable for electric motors.
As is known, in order to supply power to electric motors, and particularly to submersed motors, hermetic connectors are commonly used which are composed of two portions that can be mated mechanically, one shaped like a plug and the other one shaped like a socket, which connect in a protected manner the electrical contacts of the motor to the power supply line derived from the mains.
Generally, this type of connector offers only an electrical insulation between the outside environment and the conductors that are live, without applying any action to the power supply line.
However, in order to avoid radio interference and overvoltages, filters constituted by simple electronic circuits arranged at the windings and provided in practice by means of varistors, gas-filled diodes or other electronic components, are usually inserted in the power supply circuit of electric motors.
The fitting and wiring of these filters is generally performed by specialized personnel, which must install them by repeating a series of operations which, in addition to considerably affecting production times, may lead to errors in the connections, with consequent malfunction of the motors.
