Definitions

  • the present invention relates to an electrical connector, in particular of the cylindrical type with plug and socket.
  • the invention particularly aims to provide a shielded connector structure, waterproof, electrically isolated from the outside to protect its user and which allows electrical wiring and easy repairs.
  • the invention provides an electrical connector of the type comprising a plug and a complementary base and in which the plug comprises a metal plug body which receives a plug insulating block, the through cells of which receive electrical contact elements, and a bayonet type coupling nut rotatably mounted on the front end of the plug body, characterized in that the rear end of the plug body comprises a hollow metal plug body extension which delimits a rear wiring chamber and of which the rear free end edge tightens the shielding braid of the electric cable to be connected against the front face opposite a clamping ring, and in that it comprises an insulating external clamping sleeve, the front free end is screwed onto the rear part of the plug body and the rear free end of which has an internal radial shoulder which cooperates with the rear face against the clamping ring to cause the shielding braid to be tightened by screwing the clamping sleeve onto the plug body.
  • FIG. 1 of which is a view in axial section of an electrical connector in accordance with the teachings. of the invention and of which Figures 2 and 3 illustrate two methods of isolating the base.
  • FIG. 1 an electrical connector 10 consisting of a female connector element, or plug, 12 and a male connector element, or socket 14.
  • the two elements 12 and 14 are shown in the coupled position.
  • the plug 12 includes a metallic plug body 16 inside which is insulated a block of insulating material 18.
  • the insulating block 18 includes through cells 20 each of which receives an electrical contact element 22 which is introduced axially into the cell from the rear face 24 of the insulating block and in which it is fitted elastically.
  • the electrical contact elements 22 of the plug are male contact elements which cooperate with complementary female contact elements 23 arranged in the insulating block of the base.
  • the structure of the insulating blocks is perfectly symmetrical and makes it possible to reverse the arrangement of the male and female electrical contacts with respect to the embodiment illustrated in the figure, the concept of female connector element or plug being to be understood independently of the type of electrical contact element which it receives.
  • the front end portion 26 of the plug body is equipped with a metal bayonet coupling nut 28.
  • the axial retention of the nut 28 and the electrical continuity between the nut 28 and the plug body 16 are provided by means of a spring 30 of known structure shown schematically.
  • the rear part 32 of the plug body 16 has an internal thread in which the end is screwed. free threaded front end 34 of a plug body extension 36.
  • the extension 36 is a metallic element in the form of a hollow socket, the internal bore 38 of which delimits an internal wiring chamber 40 intended to receive the wires to be connected to the elements 22 of a shielded electric cable of cylindrical section with a braid of peripheral shielding (not shown).
  • the free rear end edge 42 of the extension 36 has a hollow frustoconical profile section which is designed to cooperate with the front face of complementary profile 44 of a clamping ring 46 made of insulating material.
  • a bi-conical metal ferrule 48 is interposed between the end 42 and the face 44.
  • the ferrule is designed to receive the end of the metal braid for shielding the cable so as to ensure the tightening of the latter between the end 42 and the corresponding face 50 of the ferrule.
  • the sleeve 52 has an internal bore 54 in which the cylindrical body of the extension 36 is received.
  • the front end of the bore 54 has an internal thread 56 which is screwed onto a corresponding external thread formed in the external surface of the rear part 32 of the plug body 16.
  • the bore 54 is delimited axially towards the rear by an internal radial shoulder 58 whose internal radial face 60 cooperates with the radial face opposite 62 of the clamping ring 46, with the interposition of a washer 64.
  • the clamping ring 46 is made of elastomeric insulating material and is extended axially towards the rear by a "wire-passing" guide tube 66 which passes through the shoulder 58 by an internal bore 68 of the latter to extend outwards. of the sleeve 52 towards the rear.
  • the guide tube 66 is provided to cooperate with the outer wall of the sheath of the cable to be connected.
  • the insulating clamping sleeve 52 extends axially forwards beyond the tapping 56 by an annular portion 70 which covers the external surface of the plug body 16.
  • a sealing ring 72 mounted in a groove 74 in the plug body cooperates with the internal cylindrical surface of the extension 70.
  • extension 70 is provided to cooperate with a corresponding annular extension 76 which extends axially towards the rear and extends a coating 74 made of insulating material which covers the nut 28.
  • annular portions 76 and 70 overlap axially in all the relative positions of the coupling nut 28 relative to the plug body 16 so as to ensure continuity of the external electrical insulation of the plug from the free front edge 82 from the nut to the insulating guide tube 66.
  • the base 14 also comprises a metal base body 84 and an insulating block 86.
  • the front end portions 26 and 88 of the plug body 16 and base 84 penetrate into each other in the coupled position and a seal 90 is interposed between these two portions.
  • the front edge 85 of the base body 84 it is possible to provide for the front edge 85 of the base body 84 to extend axially so as to come into axial mechanical abutment against the face opposite 89 of the external radial shoulder 91 of the plug body.
  • This mechanical stop has the effect of improving electrical ground continuity and also of avoiding excessive crushing of the seal 90 during coupling.
  • a seal 92 is also arranged between the insulating block 86 and the base body 84, just as a seal 17 is arranged between the insulating block 18 and the plug body 16.
  • Sealing is also ensured between the electrical contact elements and their cells due to the elasticity of the insulating material of the insulating blocks. According to a variant not shown, it was possible to arrange a sealing ring around each contact which cooperates with the bore of the corresponding socket.
  • FIG. 2 illustrates a first embodiment of the insulation of the base body 84.
  • a nut made of insulating material 92 is screwed onto the body 84. It has an axial annular extension 94 which extends axially forward and overlaps the insulating coating 78 of the locking nut 28.
  • the mounting nut 92 of the base is metallic. It is covered by the rear skirt 96 with an insulation nut 98 which is also screwed onto the base body 84.
  • the insulation nut 98 also has an annular extension 90 as in the case of FIG. 2.
  • the front face of the panel 100 which receives the base can also be covered with an insulating material.
  • each of the two connector elements can be fitted with a closure plug whose body is metallic and whose outer wall is coated with insulating material.
  • connection of the plug on the cable with the presence of the wiring chamber 40 makes it easy to repair and / or replace a contact element 22 by unscrewing the extension 36 and this even in the event of very high density electrical contact elements.
  • the unscrewing of the extension can be facilitated by an external gripping area, for example knurled.
  • the extension 36 can be of very small size axially to form a very short wiring chamber and, in the latter case, be produced in one piece with the plug body 16.
