Definitions

  • the present invention relates to an electrical connector element of the type comprising an insulating block in which is formed at least partially at least one through cell which receives an electrical contact element.
  • the object of the invention is to propose an electrical connector element design which allows the mounting of contacts by one side of the insulating block and its at least partial disassembly, in particular to allow repair thereof, by the other side of the insulating block. .
  • the invention provides an electrical connector element characterized in that the electrical contact element comprises a central contact body received in an intermediate socket itself received in the cell of the insulating block with respect to which it is immobilized axially in a first direction by cooperation of two shoulders formed vis-à-vis respectively on the sleeve and in the cell, and in a second direction by cooperation of two other shoulders vis-à-vis between which a ferrule is interposed external support erasable from one of the end faces of the insulating block, the contact body being immobilized axially with respect to the sleeve in a second opposite direction by cooperation of two shoulders formed opposite each other respectively on the body contact and in the socket, and in said first direction by cooperation of two others facing shoulders between which is interposed an internal shroud erasable from the other end face of the insulating block.
  • the external and internal ferrules each have elastically radially inwardly deformed fingers which cooperate respectively by their free ends with an external radial shoulder of the sleeve and an external radial shoulder of the contact body.
  • connection assembly of two mother and daughter printed circuit boards of the type described and shown in French patent application n ° 89 07264, the content of which may be referred to for the structure thereof and design details.
  • the connection assembly comprises two connector elements, a plug 10 and a base 11 for the electrical connection of electrical tracks formed respectively on a daughter board 12 and a motherboard 13.
  • the plug 10 comprises a hollow peripheral frame of rectangular section 14 in which a block of insulating material 16 is received.
  • the insulating block 16 receives electrical contact elements in small cells. female 18 allowing for example the transmission of an electrical signal.
  • the electrical contact elements 18 protrude axially beyond the rear face 20 of the plug insulating block 16 so as to be connected to one of the faces of the motherboard 12 by means of connection grids 22.
  • the front ends 24 of the contacts 18 project axially beyond the front face 26 of the insulating block 16 in the direction of the base 11.
  • the insulating block 16 has in its middle part a through slot 28 which receives a ground connection strip 30, the front end 32 of which projects axially in the direction of the base 11 beyond the front face 26 of the block 16.
  • a male power contact 60 In a large cell 34 formed at the top of the insulating block 16, the latter receives a male power contact 60, the rear part of which is held and immobilized axially in a large cell 36 of the plug frame 14 which extends the cell 34 of the insulating block 16.
  • the power contact 60 is mounted from the rear in the plug 10 and is immobilized there axially in the direction of the rear by a retaining ring 40 comprising elastically deformed fingers radially inwards which cooperate with a retaining shoulder 42 of the external contact body of the contact 60.
  • the base 11 symmetrically comprises a peripheral frame 15 of rectangular section in which is received an insulating base block 17.
  • Small cells receive three male electrical contact elements 19 provided for cooperating electrically by their front ends 25 with the front ends 24 of the female contacts 18.
  • the signal male electrical contacts 19 extend axially towards the rear of the base 11 beyond the rear connection face 21 of the insulating block 17 to penetrate corresponding tap holes 23 of the motherboard 13.
  • the face front of connection 27 of the insulating block of base 17 is in abutment against the front of connection 26 of insulating block of plug 16, the front ends 24 of the female electrical contacts penetrating into corresponding cells of the insulating block 27 formed around the free ends front 25 of the male electrical contacts 19.
  • the insulating base block 17 has a slot 29 in which a ground connection strip 31 is received, the front end of which in the form of a clamp 33 receives the front end 32 of the ground strip 30 of the plug 10.
  • the insulating block 17 and the base frame 15 have large cells 35 and 37 which receive the rear part of a female power contact 61 complementary to the male contact 60.
  • the female contact 61 has an original structure allowing it to be mounted from the rear and its partial disassembly for repair from the front as well as a transverse movement in the direction D.
  • the female contact body 63 is extended towards the rear by an internal shouldered cylindrical sleeve 65 which is disposed in an intermediate shouldered socket 67 which is itself received in the cells 35 and 37.
  • the axial positioning and holding of the intermediate socket 67 in the cells is conventional and identical to that of the male contact body 60, that is to say by means of a ferrule with internal elastic fingers 41 whose ends cooperate with a shoulder 69 itself in abutment against a shoulder in vis-à-vis 71 of the insulating block.
  • the internal cylindrical sleeve is positioned and held in the intermediate sleeve 67 by means of an internal retaining ferrule 73 of structure similar to that of the external ferrule 41.
  • the arrangement of the internal ferrule is axially reversed so that the free ends of the fingers deformed radially inwards are in abutment against a face opposite 75 of the rear shoulder of the internal sleeve 65.
  • a split annular ring 77 is mounted between the stepped inner sleeve 65 and the inner ferrule 73 so that it can be pushed axially towards the rear via its projecting end 79 in order to allow disassembly from the front of the body contact 61 and sleeve 65.
  • the end 79 can be omitted and replaced by a tool, not shown, which is made to penetrate inside the female power contact by the slots 81 provided for the end (s) 79, the ring 77 being a split ring permanently mounted in the contact.
  • the first assembly of the female power contact is done by introducing from the rear into the cells 35 and 37 the assembly constituted by the intermediate socket 67 and by the contact body 61 itself, the latter having already been positioned in the intermediate sleeve 67.
  • a high conductivity copper conductor 85 has been introduced inside the stepped sleeve 65 until its free end 87 can be brazed from the front into the contact body 61 before mounting in the alveoli.
  • An axial clearance D is made possible by the small cross section of the conductor 85 which is received with a radial clearance in an internal bore 91 of the sleeve 65.
  • the internal sleeve 65 and the conductor 85 form a single element of larger diameter without radial clearance.
  • the female power contact shown in the figure retains the conventional repair function by extraction from the rear by acting on the ferrule 41 which makes it possible to extract the entire contact including the intermediate socket 67 by means of a conventional ring-shaped tool introduced into the radial clearance provided for this purpose.
  • the original combination of two external and internal erasable ferrules thus allows the rear mounting of the power contact and its at least partial separation by extraction from the front without having to dismantle the entire base 11 of the card 13 .
  • connection assembly for connecting mother and daughter printed circuit boards but is applicable to all types of known connection assemblies and whose applications may require mounting in a first direction and at least partial disassembly in a second opposite direction.
