  • Such an electrical connector is known, in particular according to the XLR standard, in which the contact elements of the cable connector in the form of contact sockets and the mating contact elements of the mating connector are formed in the form of contact pins which can be plugged together in the axial direction.
  • XLR plugs are especially popular for audio applications.
  • the latching part is biased by a leaf spring of the insert part in its outwardly pivoted position in which the latching lug of the locking part over the circumference of the plug housing protrudes outwardly and engages in the assembled state of the connector in a recess of the mating connector, which from a window opening in the plug housing of Mating connector is formed.
  • an electrical connector with quick lock is known.
  • the plug has a cranked outer sleeve, which releases the quick lock by axial displacement.
  • the sleeve is not under spring tension.
  • US 5 637 010 A shows a male coupling with locking mechanism.
  • the plug has an outer sleeve which is spring biased and holds the latch upright. By axial movement of the sleeve, the connection can be solved.
  • US 2004/137778 A1 shows a snap connection of a male coupling with an outer sleeve, which can solve the lock by axial displacement.
  • the plug is coaxial.
  • the sleeve is not spring loaded.
  • the object of the invention is to provide an improved electrical connector of the type mentioned, in which a mutual wobbling of the nested connector is counteracted and in which a good and reliable annular contact between the connector housings of the two connectors can be achieved. According to the invention, this is achieved by an electrical plug connection with the features of claim 1.
  • the sliding sleeve allows also a simple release of the latching and opening of the electrical connector, wherein when moving the sliding sleeve in its rear open position, the latching lug is moved inwardly so that it comes out of engagement with the latching recess.
