Definitions

  • the present invention relates to a fast-acting self-stripping connection, applicable in particular to the production of a distribution terminal block making it possible to connect a plurality of conductors to a common strip, by self-stripping.
  • An object of the present invention is to provide a self-stripping connection in which the connection of the conductors can be carried out simply, without any other tool than an ordinary screwdriver, and quickly, by a rotation of the screwdriver for example less than 180 °.
  • Another object of the invention is to provide a connection in which a simple screwdriver makes it possible to remove the conductors already connected.
  • the invention relates to a self-stripping connection for connecting conductors to a metal strip provided with self-stripping contacts comprising sharpened parallel edges, characterized in that it comprises a means for pushing the conductor on said contacts, actuated by screwdriver.
  • said pushing means comprises a well containing a screw immobilized in translation and whose rotation under the action of said screwdriver causes the axial translation of a threaded pusher cooperating with the screw and immobilized in rotation.
  • the invention also relates to a terminal block comprising at least one self-stripping connection as defined above.
  • the terminal block comprises a plastic box divided into compartments, each compartment comprising self-stripping contacts, a well provided with a screw and a pusher, an opening being made in the box, for each compartment, between the base of the pusher and said self-stripping contacts, to allow the introduction of a conductor to be connected, said opening being in communication with a slot parallel to the edges of the self-stripping contacts.
  • said slot is provided with lips allowing the conductor to be pinched after connection.
  • said lips have come from molding with the housing.
  • the height of the self-stripping contacts is equal to a multiple of the diameter of the conductors to be connected.
  • said slot extends, without lips, below the level of the self-stripping contacts, to allow the extraction of a conductor by simple pushing, for example using said screwdriver.
  • connection terminal block that of a connection terminal block, but it should be understood that the fast-acting self-stripping connection of the invention can be applied to any type of device in the field of connectors.
  • the terminal block includes a plastic casing, advantageously made up of two interlocking portions, generally referenced A and B (see Fig. 3).
  • the assembly defines a substantially parallelepiped housing comprising a front face 1, a rear face 2, a top 3 and a bottom 4 which can be secured to a metal fixing rail 5.
  • Part A comprises the face 1, the bottom 4 and the lower part of the face 2.
  • the part B comprises the top 3 and the upper part of the face 2.
  • the housing comprises transverse partitions 11 defining a plurality of parallel compartments 12 which can each receive one or more conductors.
  • the partitions 11 are provided with aligned holes allowing the engagement of a metal bar 13 (see Fig. 3 to 5); the conductors must be electrically connected to this single bar.
  • the length of the housing depends on the number of connections to be made.
  • an ear 7 molded allows the housing to be fixed.
  • the strip 13 is secured to self-stripping contacts (see FIG. 5) generally designated below by the reference 16; these contacts are constituted by a plate 16 folded back so as to define two parallel portions 16A and 16B terminated by converging ends 16'A and 16'B whose sharp edges are distant by a length slightly less than the diameter of the metal of the conductors to connect.
  • the plate 16 is secured to the bar by crimping to pins 13A of the bar of a portion 16C suitably folded.
  • the housing comprises, for each compartment 12, a portion in the form of a well 21.
  • This well is disposed above the self-stripping contacts 16 which have just been described, and contains a screw 22 having a threaded body 22A and a head 22B provided with a slot 22C capable of receiving the end of a screwdriver 24.
  • the head of the screw is engaged between two circular edges 21A and 21B of the part 21, so that the screw can rotate, but that it is immobilized in translation; the screw is intended to move a pusher 25 comprising a prismatic portion 25A internally threaded, screwed to the screw 22, and secured by a bottom 25B to a prismatic end portion 25C; the section of the well comprises two opposite parallel faces, it is the same for the prismatic portion 25A; in this way, the part 25A is immobilized in rotation and can only move in axial translation.
  • the section of the part 25C visible in particular in FIG. 5, is substantially that of a diabolo, the thinned part being able to engage between the sharp edges of the self-stripping contacts. This arrangement makes it possible to exert a regularly distributed thrust on the conductor to be connected.
  • Part A of the housing has, for each compartment, a lateral orifice with conical inlet 27, formed in the front face 1 of the housing, and intended to receive the conductors to be connected.
  • This orifice is disposed between the base of the well 21 and the upper part of the self-stripping contacts 16.
  • This orifice is in communication with a slot 28 which extends in line with the contacts 16 and the length of which is chosen according to the number of conductors that you want to connect in the same compartment. The example chosen and illustrated is that where two conductors can be connected in the same compartment.
  • the slot 28 extends at 29 below the self-stripping contacts, over a length sufficient to allow the extraction of the conductor, as will be seen below.
  • edges of the slot 28 are provided, at the level of the contacts 16, with elastic lips 31 and 32, preferably coming from molding with the housing, and intended to clamp the conductor after connection.
  • the upper part 3 of the part B of the housing is closed by a clipped bar 34.
  • the invention is economical, thanks to a small number of molded parts; its modular nature allows it to be adapted to all needs; its use is particularly easy since it does not require any of the special tools or accessories usually required in this type of connection.
