Definitions

  • the present invention relates to a connection device which comprises at minus a terminal of the type having an elastic cage and a conductive part current, this ensuring the support function for the cage.
  • connection devices of this type are well known. They are associated with an electrical device or organ and allow clamping in the terminal cable to be connected to the device or organ without having to use a screw Tightening.
  • the elastic cage is placed near one end of the support piece close to an access face of the device and comprises a support wing applied to the support piece, a clamping wing with a clamping window for conductor by wedging effect and a loop connecting the support wing to the clamping wing and forming a spring for secure the conductor.
  • connection terminals elastic, it is desirable to be able to establish a connection, not only with cables attached and held by wedging, but also with power bars, or with other devices arranged laterally or superimposed, taking advantage of the existence of the terminals in question.
  • the invention thus aims to take advantage of the elastic cage terminals provided in an electrical device to ensure the connection of a cable, so to make a simple and reliable connection with another device or with a current conducting member.
  • connection device has an insulating block which on the one hand carries a branch suitable for ensuring the opening of the elastic cage and on the other hand a connecting conductive branch, the two branches being directed substantially parallel to the support wing of the cage and arranged so that, when the block lands against the cage, the branch opening bends the loop to allow the introduction of the branch of connection in the clamping window.
  • the two branches are rigid and a space remains in clamped position between the opening branch and its housing in the direction of the elastic loop, so that the application pressure of the connecting branch on the conductive part is due to the pressure exerted by the loop on the opening branch.
  • One of the branches can be provided with a shape helping to retain the block in the connected position.
  • the insulating body also has at least one interconnection element such as a conductive pin parallel to the connection branch and connected to it to ensure the link with another device.
  • Figure 1 schematically shows a conforming connection device to the invention.
  • Figure 2 shows in perspective a particular embodiment of the device connection block.
  • FIGS 3 and 4 illustrate the device respectively at docking and connected state.
  • the electrical appliance A is an appliance low-voltage electrical type with distribution, control function or protective.
  • Device A includes several connection terminals B of elastic type capable of receiving and connecting ends of conductors C.
  • the device according to the invention comprises the terminals B as well as a block multipole D connection; block D could of course also be unipolar.
  • Each terminal B comprises an elastic cage 10 and a flat and elongated part 20 which ensures the conduction of the current and the support function of the cage.
  • the elastic cage 10 is placed on the front 20a of the support piece 20 near one end 21 thereof near an access wall 22 of the apparatus and has a support wing 11 applied to the support piece on the length thereof, a clamping wing 12 provided with a clamping window 13 of conductor by wedging effect and a loop 14 forming spring and connecting the support wing 11 to the clamping wing 12.
  • the back 20b of the part 20 is used to make contact with the cable C and for this purpose has a bump 20c.
  • the device usually comprises in its access wall 22 and for each terminal B an opening 23 for insertion of the cable C to be connected to the part 20 and an opening 24 used to engage a tool; as we know, this tool must be able to press the loop to loosen the terminal, by allowing the window 13 to be released in order to introduce or release the cable therein.
  • the support piece 20, the support wing 11 of the elastic cage 10, the openings 23, 24 of the terminal are oriented in a same direction X which is that of introduction of the cable C.
  • the direction Y of relaxation of the loop 14 and movement of the wing 12 is substantially perpendicular to X.
  • the opening 24 gives access to a housing 25 contiguous to that of the cage 10 so that the tool can debate in this housing in order to press the loop 14 opposite to the Y direction while resting on the outer edge 24a of the opening 24.
  • the block D has an insulating body 30 which carries on the one hand a branch opening 31 of the cage and on the other hand a conductive connection branch 32.
  • the two branches 31, 32 are directed substantially parallel to the support wing 11 of the cage 10 along X and arranged so that, when the body 30 approaches the apparatus A, the opening branch 31 flexes the loop 14 (see dashed lines in FIG. 3) to allow the introduction of the connection branch 32 in window 13.
  • the two branches offer a predetermined distance between them h and are rigid so that the contact pressure of the connection branch 32 on the conductive part 20 is due to the pressure exerted by the loop 14 on the branch d opening 31.
  • the two branches 31, 32 are metallic and rigidly connected to each other; the branch 31 may also be made of insulating material and possibly come in one piece with the body 30.
  • the connection branch 32 provides the desired connection of current between the piece 20 and another member or device; it can be connected in the body 30 to another plug or pin 33 (see FIG. 2) which establishes the connection with another adjacent device or with a supply device.
  • the branch 31 has a slope 31a for gradually approaching the loop 14 and if necessary an anti-extraction conformation, for example and as indicated in FIG. 3, a recessed shape 31b which cooperates with the loop or a hard point provided in one face of the housing 25 to help maintain the block D in the connected position and assembled on the device A.
  • the branch 32 has a slope 32a for sliding on the boss 20c provided at the end 21 of the part 20 and it is capable of being applied against the boss by its edge 32b located on the side of the branch 31.
  • the branch 32 can offer an anti-extraction form 32c as indicated in FIG. 4.
  • the branches 31,32 have any suitable shape, the branch 31 being for example a flat plug and branch 32 a round pin.
  • the user approaches the insulating block D of the device in the direction X.
  • pin 33 into a terminal for each pole or a connecting member, not shown, from another device or member conductor, it penetrates the opening branch 31 of block D into the opening 24 of terminal B of device A; the slope 31a of branch 31 applies on the front rounding of the loop 14, so that the loop flexes; the connection branch 12 of the cage 10 comes in the position indicated in dashes in Figure 3 to make window 13 accessible.
  • the block is retained against an extraction in the direction X 'by cooperation of the withdrawal 31b of the branch 31 with the loop 14 or with a hard point provided on one face of the housing 25 or by cooperation of the withdrawal 32c of the branch 32 with the bump 20c of the part conductive 20.
