Definitions

  • the present invention relates to an electrical appliance comprising terminals of which each has a conductive support piece bearing near one end an elastic cage intended to receive at least one conductor to be connected.
  • the elastic cages usually used in such bollards include a support wing applied or fixed on the support piece and a wing operating by jamming a tightening of the end of an external conductor to be connected, such as a cable.
  • the clamping wing is connected to the support wing by a spring loop and it has a window into which a conductor can be inserted, this conductor being wedged between an edge of the window and the support piece by the force due at the loop.
  • the invention aims to meet these wishes.
  • the conductive support piece for the cage is a piece that is substantially U-shaped with a core, a support wing on which is applied the support wing of the cage and a guide branch for a plug connection, the connection plug being inserted in the direction of the core and applicable between said branch and the loop of the elastic cage.
  • the support piece can be dimensioned to receive two spring cages arranged side by side in a direction parallel to the two wings.
  • the planned distance between the loop of a spring cage and the second wing is sufficient to receive a connection plug.
  • the terminal can be arranged to house a plug side by side distribution for the power supply of the device and a connection cable to a other device.
  • Figure 1 shows a side view of a terminal according to the invention housed in a electrical appliance.
  • FIG. 2 is a perspective view of a variant with a double terminal.
  • the electrical appliance part of which is shown schematically in the figure 1 comprises a housing made of insulating material 10 and several terminals with elastic cage Protected by a housing part, a cover or other similar member of recovery 11.
  • Terminal A has a conductive support piece 12 bearing on a wing 12a a spring cage 13.
  • the spring cage 13 comprises a support wing 13a applied on the wing 12a of the support piece, a clamping wing 13b and a loop 13c; the clamping wing 13b is connected to the support wing 13a by the loop 13c which forms a spring and it has a clamping window 13d into which enters and remains engaged the end of the wing 13a.
  • Clamping window 13d has an edge 13e applicable against the side of the wing 12a opposite to that which carries the wing 13a; the window 13d is used to clamp at least one conductor C, with wedging effect between the edge 13th and wing 12a.
  • the wing 12a of the part 12 can advantageously offer an end free curved or convex 12e which enters the window 13d of the spring cage and facilitates cable entry.
  • the conductive support piece 12 is generally U-shaped and has the wing 12a already mentioned, as well as a core 12b and another wing 12c.
  • the wing 12c extends substantially parallel to the wing 12a or may be slightly inclined relative to the wing 12a.
  • the wing 12c forms a guide branch for a tool B which is used to deform the loop 13c (see figure 1), in order to release an opening window 13d and thus ensure the passage of the conductor, or for a plug connection D; the wing 12a advantageously has a convex free end 12d (see Figure 2).
  • the part 12 retains, opposite the core 12b, a wide opening which allows a satisfactory access to conductors C, plugs D and tools B via appropriate openings 11c and 11b, d of the cover 11.
  • FIG. 2 a double terminal according to the invention.
  • the spring cages 13 are housed one next to the other in the part 12.
  • a stiffening arm 16 in the form of a bridge takes root on the wing 12c and is supported by a shoulder 16a on the wing 12a, of so that this results in better rigidity for the support piece and for the entire terminal.
  • the core 12b of the part 12 having a length a , or even a distance a being provided between the support wing (12a) and the guide branch (12c), it can be observed that the distance b provided between the loop 13c of the spring cage 13 and the second wing 12c is sufficient to accommodate between them a connection plug D and that the arrangement adopted makes it possible to house, in the same location and with minimal bulk, a power plug D and a cable starting C.
