Definitions

  • the invention relates to a socket safety system, intended for the overheating protection of the terminals of the plug in case of its weak contact in the terminals of the socket.
  • the disadvantages of the solution are that with the time of use and / or with the increase of the temperature due to the high current intensity at the contact, the firmness of the contact between the blade system and the terminals of the power supply decreases, leading to increased contact resistance.
  • the technical problem solved by the invention consists in the realization of a socket safety system, , which uses a system consisting of two springs, destined to the protection to overheating of the terminals of the plug and to the increase of the force at the contact level.
  • the socket safety system eliminates the disadvantages presented by the fact that it consists mainly of a system of Nitinol springs whose response to the increase in temperature leads to a compression of them, ensuring an increase in force and therefore a contact firmly with the coupling terminals.
  • the socket safety system consists mainly of two identical, elastic parts, identical, in shape of horseshoe arch 1 and 1 ′, each piece being provided with two channels 2 and 2′ respectively 2 ⁇ , 2 ⁇ ', by which moves in the longitudinal direction a guide piece 3 and 3′, provided at the ends with two nitinol springs 4 and 4′ and, respectively, 4 ⁇ , 4 ′′′, tensioned and rigidly attached to the socket support.
  • the guide pieces 3 and 3′ When the terminals of a plug are inserted into the socket, the guide pieces 3 and 3′ will move by tensioning the springs with nitinol 4 and 4′ respectively 4 ⁇ , 4 ′′′.
  • the guide pieces 3 and 3′ When the current through the socket, at the level of the electrical coupling, increases, the guide pieces 3 and 3′, will heat up and the temperature will be taken over by the springs with nitinol 4 and 4′ respectively 4 ⁇ , 4 ′′′, which under its action will be compressed by changing the elastic constant of the spring, achieving an increase in pressure force and thus a firm tightening of the terminals of the plug, thus avoiding imperfect contact and heating of the plug and the elastic parts in shape of horseshoe arch 1 and 1′, respectively the reduction of the contact resistance between the consumer and the supply voltage.
  • the tightening is directly proportional to the temperature released.
  • the socket safety system according to the invention can be reproduced with the same performance and characteristics whenever necessary, which is an argument in favor of compliance with the criterion of industrial applicability.
