Definitions

  • the present invention relates to electrical connectors particularly intended for the measurement and control of electronic telecommunications equipment circuits.
  • a connector is used specific to the type of measurement to be carried out, that is to say a connector carrying out a coupling in shunt on the circuit to be tested for a measurement of a voltage and a connector carrying out a coupling in series. by breaking the circuit for current measurement.
  • An object of the present invention is to provide an electrical connector allowing, by itself and without any adaptation, to carry out either a branch coupling or a series coupling by breaking the circuit to ensure, consequently, a voltage measurement or a current measurement at a point in a circuit.
  • the present invention also aims to achieve, from said multiple coupling connector, a first multiple measurement connector for electronic equipment circuit boards mounted in a chassis, allowing measurements at points on the circuits of individual cards, accessible from the free face known as the front face of the chassis, and a second multiple connector also for measuring electronic circuit boards mounted in a chassis allowing measurements at points on the circuits of individual cards, not accessible while the card or cards are test remain in the chassis.
  • FIGS. 1A and 1B an embodiment of the multiple coupling connector according to the invention is illustrated, formed by a socket 1A and a plug 1B capable of engaging in the socket.
  • the socket 1A comprises a housing 2 made of an insulating material and mounted on one of the edges of a printed circuit board 3 carrying a pair of contact terminals 4 and 5 between which it is desired to produce a defined coupling, i.e. a branch coupling or a series coupling, using plug 1B.
  • the plate 3 carries, on the same face and in the vicinity of its edge inserted in the housing, the two contact terminals 4 and 5.
  • These two terminals are defined by the terminal portions of two conductive tracks 6 and 7 printed recto-verso on the wafer 3, one of the tracks, here the track 7 being brought back to the face carrying the other track, 6, through a metallized hole 8, so that the two terminals are arranged facing each other near the edge of the wafer with a different spacing from this edge.
  • the contact terminals 4 and will be connected, in particular by the conductive tracks 6 and 7 to an electronic circuit to be tested, not shown, carried or not, by the plate 3.
  • the housing 2 has an internal cell 11 in which is housed a conductive jumper 12, in the shape of an inclined U.
  • the ends of the branches of this jumper are curved and have between them the same spacing as that existing between the contact terminals 4 and 5 on which they are, in the socket 1A considered independently of the plug 1B, in elastic connection as shown by marks 14 and 15.
  • the housing 2 also has an opening 16 for inserting the plug 1B into the socket 1A.
  • This opening 16 formed in the face of the housing opposite to that receiving the wafer and called the front face, opens into the cell 11 so that the plug 1B inserted in the socket 1A according to the arrow F comes to be inserted between the terminals of contact 4 and 5 and the ends of the branches of jumper 12 by removing. the elastic connections 14 and 15 which existed directly between them.
  • the jumper 12 is held in the cavity 11 by embedding a portion adjacent to its base and deformed to form a shoulder 17 bearing in the internal wall of the corresponding profile of the housing , above the opening 16. Jointly, a lug 18 cut out from the base of the jumper is housed in a retention groove 19 formed in the housing; for blocking the rider whose ends of the branches form support springs on contact terminals 4 and 5.
  • the housing 2 made of insulating material will come from molding.

  • the pair of contacts, ie 26-27 is defined by two deformations, in the form of a boss constituting elastic spring, of the same strip, ie 21; these contacts 26-27 belonging to the same strip 21 are in permanent electrical connection.
  • the second pair of contacts, 28-29 is defined by two deformations, also in the form of a boss constituting elastic spring, of the terminal portions opposite one and the other of the lamellae. 21 and 22; these contacts 28-29 are therefore without direct electrical connection with each other.
  • the two other end portions of the two conductive strips 21 and 22 extend recto-verso in the vicinity of the edge of the support 20, received by the base; they are connected inside the base 23 to the two conductors 24 and 25 to which will be connected the appropriate measuring device according to the test to be carried out, therefore the coupling produced between the terminals 4 and 5 by the plug 1B.

  • FIGS. 4, 5 and 6 a first application of the socket and the plug according to FIGS. 1A and 1B has been illustrated in the production of a connection strip 10 with multiple sockets and of an associated multiple plug 10B, for measurements at a plurality of points on an electronic circuit carried by a card, brought to one of the directly accessible edges of the card in global electronic equipment to which it belongs.

  • the strip 40 has, on its front face a series of openings 48 opening into the respective cells, for the insertion through each of them of a multiple plug 10B interposed between the set of pairs of contacts concerned and the set of conductive jumpers that corresponds to it.
  • the strip 10 thus produced is therefore constituted by a series of 'multiple sockets, designated by the general reference 10A, the different sets of pairs of contact terminals of which are carried by the same printed circuit board.
  • the strip 40 does not cover simply that one of the contact terminals of each of the pairs of successive contact terminals which extend along the edge of the card which it receives.
  • the sets of conductive jumpers 47 are therefore not completely housed in the cells of the strip but partially protrude therein so that the ends of their branches normally come in elastic connection on the contact terminals of the different pairs.
