Definitions

  • the present invention relates to an electrical connector, in particular of the Jack and DIN types in conjunction with a socket in a cabinet.
  • Plugs of the Jack and DIN types are widely used in conjunction with low voltage equipment and installations and are so well-known that they do not require more detailed description.
  • the plugs are only retained by compression forces in the socket and are easily removable and there is a risk that they may be inadvertently disconnected. In certain cases it is desirable and sometimes required that this cannot take place.
  • hospital beds where the mattress support may be adjusted by means of a system of electric linear actuators. The beds are washed and disinfected when the patients are discharged, typically in automatic washing plants. In this situation it would be unfortunate if a plug were not in its proper place because water and disinfectant might enter the socket and thereby disturb or in the worst case hurt the electronics inside. Disinfectants are aggressive compounds which may attack electronic parts.
  • the electrical connection in particular of the Jack and DIN types in conjunction with a socket in a cabinet is particular in that it comprises a union nut which surrounds and retains the plug and where the union nut is secured against undesired removal by an axially displaceable locking element in conjunction with the side wall of the union nut which may be displaced between an inoperative position and a locking position where the element engages the cabinet directly or in-directly.
  • the construction becomes particularly simple and user friendly by letting the axially displaceable element form part of the side wall of the union nut, preferably as a section of the union nut. In the active locking position the union nut will look like a standard union nut.
  • the locking element is preferably retained by a tongue-and-groove joint to the union nut.
  • the union nut with the element appears as a solid whole.
  • the tongue-and-groove is slightly slanted towards the centre of the union nut, the ring is furthermore tightened by the insertion of the element.
  • the union nut with a springforce might squeeze around the element.
  • the locking element advantageously locks in that the end facing the cabinet has a cut-out designed for engaging a projection in the cabinet.
  • the end of the locking element may grip into an under-cut in the cabinet.
  • the union nut is preferably shaped with an outside recess, and the locking protrusion is fitted at some distance from the socket and has a height such that the recess may pass between the protrusion and the socket, and furthermore that the wall element has a length and thickness so that the cut-out engages the locking protrusion.
  • the locking protrusions are advantageously disposed such that neighbouring plugs share a locking protrusion.
  • the plug is preferably made with a bayonet lock.
  • An alternative embodiment has a thread.
  • the sockets are preferably fitted into a cylindrical piece on the outside of the cabinet as against a countersunk fitting.
  • a connection which is fluid tight may be obtained by means of o-rings in which case it is preferable to mount a single o-ring in a groove on the outside of the body of the plug.
  • the o-rings could be fitted in the sockets.
  • Fig. 1 of the drawing there is schematically shown a section of a cabinet 2 with six sockets, with a jack plug 4 being inserted into the nearer socket 6.
  • the socket 6 comprises a short cylindrical part 8 which projects from the cabinet.
  • a circular groove 9 at the front of the jack plug 4 there is fitted an o-ring which is not shown for obtaining fluid tightness when the plug is fitted into the socket.
  • a recess 10 In the entrance to the socket there is placed a recess 10 which cooperates with a collar 12 on the plug in forming a stop for further movement of the jack into the socket.
  • the union nut may, however, be completely locked by means of a locking element which is in the form of an axially displaceable wall element 20 in the union nut, cf. Fig. 3.
  • a locking element which is in the form of an axially displaceable wall element 20 in the union nut, cf. Fig. 3.
  • the wall element is provided with a tongue 22 on the side edges which cooperate with corresponding grooves 24 in the sides in the opening in the union nut.
  • the first set of tongue-and-groove joints retain the wall element in the in the ring-shape of the union nut while the second set holds the nut and wall element together.
  • the tongues 22 on the side edges of the wall element end at the bottom in a leg 34 with a hook which, when the element is fitted, catches the recess 32 and further prevents the wall element from being unintentionally extracted.
  • the thickness of the side parts of the wall element is balanced in order that the full wall thickness of the union nut is obtained in cooperation with the wings in the opening, while the central part already has this thickness.
  • the wall element has the full height of the union nut, i.e. it has no terminating recess at the inner end.
  • the union nut retains the jack plug by having a collar 40 at its front end which cooperates with the stop collar 12 on the plug.
  • the plug projects with its rear end through the union nut, as the hole corresponds to the thickness of the rear end.
