Definitions

  • the invention relates to a first part of a connector and a second part of a connector.
  • a further hazard occurs when a current-carrying connector and in particular a DC-conducting connector are separated, i. when the plug is pulled out of the socket, as it may physically lead to the formation of an arc, which may result in, among other things, serious injury or even the death of persons located in the immediate or immediate vicinity of the connector. Furthermore, as a result of the arc, the air and creepage distances are reduced by the occurring ionization, so that it can lead to destruction of equipment and system components, so that even if no personal injury occurs material damage can occur.
  • any opening of live connectors may result in undefined and critical equipment and machine conditions.

  • An embodiment of the first part of the connector as a socket or as a plug represents a common embodiment of the first part of the connector.
  • the locking device comprises an actuator which moves based on a thermal deformation due to a current flow or based on a polymeric deformation due to a voltage applied to the actuator or based on a generation of a magnetic field due to a current flow, a closing element which cooperates with the locking element of the second part of the connector such that the mated first and second part of the connector are not separable from each other.
  • the locking element is designed as a tab which protrudes from the second part of the connector.
  • An embodiment of the locking element as a tab, which protrudes from the second part of the connector, represents a particularly simple embodiment of the locking element.
  • the tab has a hole, since then the closing element particularly simple, e.g. as a bolt, can be formed.

  • the first part 2 of the connector has a first pin receptacle 5a for receiving a first pin 4a of the second part 3 of the connector and a second pin receptacle 5b for receiving a second pin 4b of the second part 3 of the connector. Furthermore, the first part 2 of the connector has a locking element holder 8 for receiving a locking element 6 of the second part 3 of the connector.
  • the first pin 4a and the first pin receptacle 5a are electrically conductive and form a first electrically conductive connection between the first part 2 of the connector and second part 3 of the connector in the mated condition.
  • the second pin 4b and the second pin receptacle 5b are also electrically conductive and form in the mated condition a second electrically conductive connection between the first part 2 of the connector and the second part 3 of the connector.
  • a current flowing through the connector I 1 thus flows through the electrical line 17 a, via the first pin 4 a, via the first pin receptacle 5 a and via the electrical line 18 a and flows via the electrical line 18 b, the second pin receptacle 5 b, the second pin 4 b and back via the electrical line 17b.
  • the second part 3 of the connector has a locking element 6, which is formed in the context of the embodiment as a tab which protrudes from the second part 3 of the connector.

  • the first pin 4a together with the first pin receptacle 5a forms a first electrically conductive connection and the second pin 4b forms a second electrically conductive connection together with the second pin receptacle 5b, so that the voltage U between the first and the second electrically conductive connection Connection is present.
  • the locking device 9 cooperates with the locking element 6 in such a way that the mated first and second part of the connector can no longer be separated from one another are.
  • the connector is in such a manner against separation, ie against opening when it is live, ie an electrical voltage between the lines 17a and 17b and thus also between the lines 18a and 18b is applied, locked.
  • the closing element 10 of the locking device 9 is moved into the hole 7 of the locking element 6 upon occurrence of the voltage U and thus causes a locking against withdrawal of the second part of the connector from the first part of the connector.
  • the first and second part of the connector are then no longer separable from each other by a person, ie the second part of the connector can not be pulled out of the first part of the connector.
  • the locking element 6 can have a variety of shapes that are adapted to the closing element accordingly.
  • the closing element may thus be e.g. may also be in the form of a hook, e.g. engaged in notches of the locking element, so as to ensure a lock.

  • a current I 2 flows (see FIG. 1 ) through the spool 11 and moves the closing element 10 through the hole 7 of the locking element 6, whereby the locking is effected.
  • the closing element 10 is retracted by a spring element 12 back to the starting position, so that the second part of the connector and the first part of the connector are again separated from each other.
  • FIG. 3 a second embodiment of the locking device 9 is shown in the form of a schematic representation.
  • the locking device 9 has an actuator, which in the embodiment according to FIG. 3 is formed as a bimetallic element 13. If the bimetallic element 13 is traversed by a current I 2 as a result of the applied voltage U, it heats up and expands so that, as shown in FIG. 3 , Bends to the left and thus the closing element 10 moves to the left, so that the closing element 10 is moved into the hole 7 of the locking element 6 and thus causes a lock. The locking device 9 thus moves the closing element 10 on the basis of a thermal deformation due to a current flow.
  • FIG. 4 a third embodiment of the locking device is shown in the form of a schematic representation.
  • the locking device 9 has an actuator, which is in the form of an electroactive polymer 14.
  • the electroactive polymer 14 deforms and moves the closing element 10, as shown FIG. 4 to the left, so that the closing element 10 moves into the hole of the locking element 6.
  • the closing element 10 is moved on the basis of a polymeric deformation as a result of a voltage U applied to the actuator 14.
