Definitions

  • the present invention relates to an electrical connector element of the type comprising an insulating block which receives electrical contact elements which extend through the insulating block and a metal shielding envelope which at least partially surrounds the insulating block in the area before the latter which is intended to be connected with the corresponding part of a complementary connector element.
  • Such a type of connector element is for example used in a set of connectors designed for the connection of the various components of transmission networks called field bus networks.
  • each link begins and ends respectively at the connection to the electronic bay for managing the system and to the subscriber's sensor, it can be envisaged that the base unit protruding from the panel metal of the bay (or of the box) is entirely plastic and the shielding is connected to the earth of the printed circuit by a simple electrical continuity by means of locking screws and metal brackets for example.
  • This part of the shield makes it possible to absorb these electrostatic discharges which are thus conveyed towards the electrical ground of the system and to prevent them from penetrating through the cutout of the panel (passage of the base) and that they do not disturb internal electronics.
  • connection and connection point are determined according to the level at which this connection point is located within the network and differ depending on whether it is '' at a start, end of line or intermediate level direct earthing of the shielding is therefore not always possible at each connector and it is therefore necessary to guarantee the safety of operating personnel ( with regard to lightning, in particular because these connections can reach several kilometers) to effectively and completely isolate all the metal parts ensuring the shielding of the connectors.
  • the invention provides a connector element of the type mentioned above, characterized in that it comprises a cap of insulating material which is attached to the front part of said shielding casing.
  • the element 10 comprises an insulating block 12 axially traversed by electrical contact elements 14 which in the case of a male connector element extend axially beyond the front face 16 of the insulating block to be connected to elements of complementary contact of a connector element not shown.
  • the insulating block 16 is surrounded by a shielding box consisting of a front half-shell 18 and a rear half-shell 20.
  • the front half-shell 18 has a front axial portion 22 in the form of a skirt which surrounds the front ends of the electrical contact elements 14.
  • the skirt 22 is extended at the rear by a plate-shaped portion 24 which extends in a radial plane which is fixed by crimping to the corresponding radial plate 26 of the rear half-shell 20.
  • the plate-shaped portion 26 is extended axially towards the rear by an axial skirt 28.
  • the metal shielding box is here fixed to a printed circuit board 30 by means of brackets 32 and harpoons 34.
  • the front half-shell 18 is capped by a molded plastic cap 36 which completely surrounds the peripheral metal surfaces of the front half-shell 18.
  • the insulating cap 36 comprises a front part in the form of an axial skirt 38 and a rear radial part 40 in the form of a plate.
  • the part 40 is extended axially towards the rear by an axial edge 42 which covers and surrounds the peripheral edges opposite the fixing plates 24 and 26 of the two half-shells.
  • the attachment of the cap 36 on the connector element 10 is ensured by means of latching tabs 44 which extend radially inwards from the peripheral edge 42 of the cap so as to cooperate with the rear face of the radial plate 26 for fixing the rear half-shell 20.
  • the size of the connector element, in its front part, is increased only very slightly and it is possible to equip the element 10, already installed on the plate 30 by coming to cap it by the front by passing the cover 36 through the standard opening 50 formed for example in a panel 52 of an electrical equipment bay.
  • the tabs 44 snap elastically around the edges of the two plates 24 and 26 which are received in the definitive notches 45 by the tabs 44, and by the face rear 41 of the plate-shaped part 40.
  • the cover has two complementary cylindrical parts 56 surrounding the nuts 54.
  • the invention is applicable to many types of connectors, to weld, to brush, to prick, etc ...
