Definitions

  • the present invention generally relates to connection terminals of the type used in electrical appliances for their connection to the electrical conductors of the electric cable proper to their power supply.
  • connection terminal according to the preamble of claim 1 is known from the document EP-0 037 758 .
  • connection terminals which are commonly called automatic clamping, that is to say those whose connection to an electrical conductor is by simply plugging the end, previously stripped, thereof , without the intervention of any tool.
  • the present invention is directed to those automatic clamping connection terminals which comprise, on the one hand, a hollow body made of conductive material which, for the insertion of an electrical conductor, opens on the outside by at least one engagement inlet, having, on either side thereof, two opposite walls, one lower, the other upper, and, secondly, a leaf spring, which has at least two branches connected continuously to one another by a rounded bend, namely, a fixing branch, which extends outside the hollow body, in contact with the lower wall of the latter; ci, being duly attached to this lower wall, and a connecting arm, which intervenes freely, in an elastically deformable manner, in the hollow body, extending generally obliquely with respect to the engagement input of this body hollow, in the direction of its upper wall, the intermediate elbow re between these two branches bypassing the front edge of the bottom wall of this hollow body.
  • the leaf spring is secured to the lower wall of the hollow body by its fastening branch, and, by its connecting branch, it ensures the tightening of the electrical conductor against the upper wall of this body hollow.
  • connection terminal of this type is particularly described in the French patent which, filed April 4, 1980, under the No 80 07675 , was published as No 2,480,037 .
  • the intermediate bend between the two branches of the leaf spring extends at a distance from the front edge of the relevant wall of the hollow body, forming, in practice, in front of this front edge, a loop which extends over more than 180 °.
  • the leaf spring carries, by another bend, on the inner face of the relevant wall of the hollow body, and on the outer face of this wall, it extends flat against this one, without any contact with its front slice.
  • connection branch which, in some applications, at least, is satisfactory, in particular because it allows a support of buttressing of the connecting branch of the leaf spring on the inner surface of the relevant wall of the hollow body and because it leads to a high elasticity for this connection branch, may, in other applications, be less satisfactory, because the axis of rotation according to which this connection branch flexes when a driver is engaged electrical is indeterminate and it follows that, this connection branch then taking a more or less random position, the mechanical strength provided, that is to say the resistance offered by the electric conductor when a pull is untimelyly exerted on him, is itself more or less uncertain.
  • German No 82 32 135.3 which, moreover, does not exactly concern a connection terminal of the same type in the measurement, at least, where, on the one hand, the elbow of the leaf spring is located on the opposite side to the engagement input of the hollow body, and where, on the other hand, it has only one wall, the clamping of the electrical conductor being on the inner surface of this wall, the spring blade is in contact with one of the slices of this wall by its elbow, in this case its rear slice.
  • the present invention generally relates to a provision to avoid these disadvantages.
  • an automatic clamping connection terminal of the kind comprising, on the one hand, a hollow body, made of conductive material, which opens on the outside by at least one engagement input, presenting , on either side of it, two opposite walls, one lower, the other upper, and, secondly, a leaf spring, which has at least two branches connected continuously one of to the other by a rounded bend, namely, a fixing branch, which extends outside the hollow body, in contact with the lower wall thereof, being duly secured to this lower wall, and a connecting branch, which intervenes freely, in an elastically deformable manner, in the hollow body, extending generally obliquely with respect to the engagement input of this hollow body, in the direction of the upper wall thereof , the intermediate elbow between these two branches bypassing the edge before e the lower wall of this hollow body,
  • this connection terminal being generally characterized in that the leaf spring, which is in contact with the front edge of the bottom wall of the hollow body by its elbow, bears against this slice before the lower edge thereof, which lower edge
  • the axis of rotation according to which the connecting branch of the leaf spring flexes when an electrical conductor is engaged is advantageously well determined, since it is materialized by the lower edge of the lower wall of the hollow body, to the benefit of the working conditions of this branch of connection, and in particular to the benefit of the mechanical strength it provides with respect to the electrical conductor.
  • connection terminal 10 comprises, on the one hand, on the one hand, a hollow body 11, made of conductive material, which opens to the outside through minus one engagement input 12, presenting, on either side thereof, two opposite walls 13, 14, one lower, forming a floor, the other upper, forming a roof, and, on the other hand, on the one hand, a leaf spring 15, which has at least two branches 16, 18 continuously connected to each other by a rounded bend 19, namely, a branch 16, which extends to the outside the hollow body 11, in contact with the bottom wall 13 thereof, being duly attached to the bottom wall 13 in accordance with arrangements described in more detail later, and a connecting arm 18, which intervenes freely, elastically deformable manner , in the hollow body 11, extending generally at an angle to the entrance e engagement 12 of this hollow body 11, towards the top wall 14 thereof, the elbow 19 intermediate between the two branches 16, 18 bypassing the front edge 22 of the bottom wall 13 of the hollow body 11.
