Definitions

  • the present invention relates to a connection device which comprises at least one terminal of the type having an elastic cage and a conductive part that current, the latter providing the support function for the cage.
  • connection devices of this type are well known, for example from DE 3911459. They are associated with an apparatus or electrical member and allow to tighten in the terminal a cable to connect to the device or the body without having to resort to a clamping screw.
  • the elastic cage is placed near one end of the support piece close to an access face of the apparatus and comprises a support wing applied to the support piece, a clamping wing equipped with a wedging clamping conductor window and a loop connecting the support wing to the clamping wing and forming a spring to secure the driver.
  • the object of the invention is therefore to take advantage of the elastic cage terminals provided in an electrical appliance for connecting a cable, in order to make a simple and reliable connection with another appliance or with a current-conducting member.
  • connection device has an insulating block which carries, on the one hand, a branch capable of ensuring the opening of the elastic cage and, on the other hand, a conductive connection branch, the two branches being directed substantially parallel to the support wing of the cage and arranged so that when the block docked the cage, the opening branch flexed the loop to allow the introduction of the connecting branch in the tightening window
  • the two branches are rigid and a space remains in a tight position between the opening branch and its housing in the expansion direction of the elastic loop so that the application pressure of the connecting branch on the conductive part due to the pressure exerted by the loop on the opening branch.
  • One of the branches can be provided with a shape contributing 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 thereto for connection with another device.
  • Figure 1 schematically shows a connection device according to the invention.
  • FIG. 2 shows in perspective a particular embodiment of the connection block of the device.
  • Figures 3 and 4 illustrate the device respectively docking and the connected state.
  • the electrical apparatus A whose outline is shown in dashed lines is a low-voltage electrical appliance with a control distribution or protection function.
  • the apparatus A comprises a plurality of elastic-type connection terminals B capable of receiving and connecting the ends of the conductors C.
  • the device according to the invention comprises the terminals B as well as a multipole-D-connection block. heard to be unipolar too.
  • Each terminal B comprises an elastic cage 10 and an elongated flat piece 20 which conducts the current and the support function of the cage.
  • the elastic cage 10 is placed on the front 20a of the part 20 of the support near an end 21 thereof close to an access wall 22 of the apparatus and comprises a support wing 11 applied to the support piece along the length thereof, a clamping wing 12 provided with a wedging clamping window 13 and a spring loop 14 connecting the support wing 11 to the 12.
  • the back 20b of the part 20 is used to make contact with the cable C and has a bump 20c for this purpose.
  • the apparatus comprises conventionally in its access wall 22 and for each terminal B an opening 23 of intreduction for the cable C to connect to the piece 20 and an opening 24 for engaging a tool: as is known, this tool must be able to press the loop to loosen the terminal by allowing the window 13 to be removed to introduce the cable therein.
  • this tool must be able to press the loop to loosen the terminal by allowing the window 13 to be removed to introduce 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 the same direction X which is the introduction of the cable C.
  • the Y direction of relaxation of the loop 14 and displacement of the wing 12 is substantially perpendicular to X.
  • the opening 24 gives access to a housing 25 adjacent to that of the cage 10 so that the tool can debate in this housing to press the loop 14 away from the direction Y by bearing on the outer edge 24a of the opening 24.
  • Block D has an insulating body 30 which carries on the one hand an opening branch 31 of the cage and on the other hand a connecting conductive 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 accosts the apparatus A, the opening branch 31 flexes the loop 14 (see dashed in Figure 3) to allow the introduction of the connection branch 32 in the window 13.
  • the two branches offer a predetermined distance between them h and are rigid so that the contact pressure of the branch connection 32 on the conductive part 20 is due to the pressure exerted by the loop 14 on the opening branch 31.
  • it remains in the clamping position of the branch 32 of the block against the back 20b of the part 20 of the terminal a space e between the branch 31 and the adjacent surfaces of the opening 24, in particular at its outer edge 24a, and the housing 25.
  • the two branches 31, 32 are metallic and interconnected rigidly; the branch 31 may also be of insulating material and optionally come from a part with the body 30.
  • the connecting branch 32 provides the desired connection of current between the part 20 and another member or apparatus; it can be connected in the body 30 to another plug or pin 33 (see Figure 2) which establishes the connection with another adjacent device or with a power device.
  • the branch 31 has a slope 31a to gradually dock the loop 14 and optionally an anti-extraction conformation, for example and as shown in Figure 3 a recessed form 31b which cooperates with the loop or a hard point provided in a face of the housing 25 to contribute to the maintenance of the block D in connected and assembled position on the apparatus A.
  • the branch 32 has a slope 32a for sliding on the boss 20c provided at the end 21 of the piece 20 and it is likely to be applied against the boss by its edge 32b located on the side of the branch 31.
  • the branch 32 may provide an anti-extraction form 32c as shown in Figure 4.
  • the branches 31,32 have any suitable shape, the branch 31 being for example a flat plug and branch 32 a round brooch.
  • the user approaches the insulating block D of the apparatus in the X direction.
  • the pin 33 into a terminal or a connection member (not shown) of another apparatus or conductive member, he causes the opening branch 31 of the block D to enter the opening 24 of the terminal B of the apparatus A; the slope 31a of the branch 31 is applied to the front rounding of the loop 14, so that the buckle flexes: the connecting branch 12 of the cage 10 comes in the position shown in dashed lines in Figure 3 to make the window 13 accessible.
  • the block is retained against an extraction in the direction X 'by cooperation withdrawal 31b of the branch 31 with the loop 14 or with a hard point provided on one side of the housing 25 or by cooperation of the withdrawal 32c of the branch 32 with the hump 2Cc of the conductive part 20. It can also be provided in the usual manner a hooking means or snap the block on the device.
