Definitions

  • the present invention is related to the field of electrical connection means, in particular plug-in connection means, able to establish an electrical and mechanical link with a wire on similar conductor without needing an additional specific positive action of the user (by using a tool or acting on a clamping means for example).
  • the invention concerns a spring loaded clamping connection terminal, and an electrical connection device incorporating at least one such terminal.
  • connection terminals Numerous constructions of such connection terminals are already known in the state of the art, such as the ones disclosed in DE 20 2013 100740 U1 , EP 2 466 689 , US 2010/0267292 A1 , DE 3302372 A1 , US 5 494 456 , EP 0 831 557 , US 8 591 271 , US 2013/0072072 and DE 197 10 306 for example.
  • DE 20 2013 100740 U1 discloses a spring clamping connection terminal according to the preamble of claim 1.
  • connection terminals are working in a satisfactory way with fairly rigid wires and conductors. But, they are not well suited for flexible wires or conductors as the engagement or triggering action, which leads to the electrical and mechanical connection, requires the transmission of a considerable pushing force along the wire or conductor. Such a force transmission is not possible with a non rigid wire, such as for example a multistrand or multi-filament wire.
  • the mechanical link usually by clamping, is established near the front end of the wire and thus is only secured by a very short length of wire, which can slip or can disaggregate into separate and loose filaments (in case of multistrand wire), thus jeopardizing the mechanical connection link.
  • connection terminals usually requires the use of a tool to undo the connection.
  • connection terminal of the type mentioned in the preamble of claim 1 improved by the features of the characterizing part of claim 1.
  • connection terminal 1 which is of the plug-in type, comprises a housing or cage 2 for receiving the bare end portion 4 of an electrical cable, conductor or wire 3 (rigid or flexible) and lodging at least one clamping arrangement 5.
  • Said arrangement comprises a spring force loaded arm 6 automatically movable between a retracted position wherein said arm 6 is located outside a passage or channel 7 following a wire insertion opening 2' of said housing 2, and allows obstacle free introduction of said bare end portion 4 into said passage or channel 7, and an extended position in which said arm 6 is at least partly located in said passage or channel 7 and is able to come into contact under elastic constraint with the end portion 4 of an electrical conductor or wire 3 received within said passage or channel 7 (and thus securing the insertion of said end portion 4).
  • Said clamping arrangement 5 also comprises:
  • connection terminal is usually located within an electrically insulated housing.
  • the trigger means 10 is located and arranged after or beyond the arm 6 and the site 9, in the direction D of insertion of the wire or conductor 3, and consists of a lever arm extending in said direction D, the contact part 11 consisting of a free end portion of said lever arm 10.
  • the invention provides simultaneously two main advantages, namely:
  • the arm 6 can be provided with a latching part 8 able to come into engagement with the respective anchoring site 9, preferably by clinging or clipping, in order to keep and to lock said arm 6 in its retracted position against the spring constraint, said mutually cooperating part 8 and site 9 forming together the locking means of said arm 6.
  • the lever arm 10 can be operatively, preferably through a force transmission or physical link, connected to the anchoring site 9 and extends beyond said site 9 in the direction D, so as to be able to displace said site 9 against a spring force and to undo the clinging or clipping engagement of the latching part 8 of the spring loaded arm 6 with said anchoring site 9, upon application of a sufficient minimal pressure or force on to said contact part 11 of the lever arm 10 located at a significant distance from said site 9 in the direction D.
  • lever arm 10 acts on the anchoring site 9 in order to release the locked spring loaded arm 6, and not on said arm 6 itself.
  • the clamping arrangement 5 is made of a single metallic strip forming the spring loaded arm 6 and a mounting frame 12 to which said arm 6 is continuously and materially connected through an elastical bendable strip portion 13 which provides the spring force load to said arm 6, said spring force being sufficient to clamp the end portion 4 of the conductor or wire 3 through said arm 6 against an opposite wall 7' of said passage or channel 7, possibly provided with a notch 7" or a similar protruding counter-clamping means able to cooperate with the arm 6 to lock the wire or cable in the passage 7 and secure the electrical contact between the end portion 4 and the conductive housing or cage 2.
  • the mounting frame 12 itself is rigidly mounted and fixed the housing or cage 2, as can be seen in figures 1 , 4 , 5 , 7 and 8 .
  • the conductive cage 2 itself can also be made from a bended metal strip, possibly together with other parts of the connection terminal.
  • the mounting frame 12 incorporates the anchoring site 9 and the corresponding latching part 8 is provided at the free end 6' of the spring loaded arm 6.
  • the free end 6' of the arm 6 can be provided with two features (hook 8 - edge 6") fulfilling two different functions, namely possible locking engagement with the anchoring site 9 and possible clamping of the bare end portion 4 of the wire 3.
  • the mounting frame can be composed of two branches or wing parts mutually arranged in an upside down L-shape or capital gamma-shape configuration with two branches 12' and 12" connected by a first curved elastically bendable portion 13, wherein the end of a first branch 12' is continuously connected through a second curved elastically bendable portion 13 to the spring loaded arm 6 and the free end 12'" of the second branch 12" is provided with the anchoring site 9, preferably in the form of a slot or an aperture, and in that the latching part 8 at the free end 6' of the spring loaded arm 6 consists of a fastening hook or a bent finger, the mounting frame 12, the curved or bent portion 13 and the arm 6 thus forming in the locked retracted position of said arm 6 a closed loop configuration.
  • the first curved bendable portion 13 provides the elastic constraint which has to be overcome in order to displace the anchoring site 9 and liberate the locked spring loaded arm 6 whose latching part is engaged with said site 9.
  • the latching part 8 and the anchoring site 9 are located with a lateral shift so as to free the insertion channel or passage 7 when the arm 6 is retracted.
  • the latching part 8 consists of a bent fastening hook extending from the free end 6' of the arm 6 and the anchoring site 9 consists in a lateral cut-out, in the shape of a slot, of the second branch 12" of the mounting frame 12.
  • the other part of the free end 6' forms the clamping edge 6" (preferably sharp) of the arm 6, which pushes the clamped wire 3 towards the notch 7" when said arm 6 is released.
  • the trigger means 10 are an integral part of the clamping arrangement 5, the clamping arrangement 5 and the trigger means 10 being preferably made of a same single metal strip.
  • said trigger means 10 can consist, when considered in the direction D, of an upside down L-shaped or capital gamma-shaped lever arm, with a first branch 14 continuously and materially connected to the clamping arrangement 5 in the region of its means 9 for locking the spring loaded arm 6 in its retracted position and with a second branch 14' forming or comprising a contact part 11 to be hit or pressed on by the end portion 4 of an electrical conductor or wire 3 inserted in the passage or channel 7 provided for in the housing or cage 2, the lever arm 10 showing a stiffness sufficient to transmit pressure forces to the clamping arrangement 5 in order to move the anchoring site 9 and to disengage the locking means 8, 9.
  • the arm 6 with its latching part 8, the elastic intermediate curved portion 13, the mounting frame 12 with the anchoring site 9 and the trigger means forming lever 10 with its contact part 11 are all made of a single metal strip through bending and cutting operations, the lever arm 10 being formed as an extension of the free end 12'" of the second branch 12" prolonging beyond the anchoring site 9.
  • the strip portion forming the lever arm 10 can also extend laterally as at least one side wall 10', in order to define a more narrow end section 7'" of the introduction channel 7 for the wire 3. Said section 7'" helps guiding precisely the end portion 4 of the wire towards the contact part 11 and can also provide lateral support for said end portion 4, able to avoid deformation of the same.
  • the free end 6' of the arm 6 can comprise side by side a latching means 8 and a clamping edge 6".
  • the latching means 8 are aligned with the corresponding anchoring site 9 and the clamping edge 6" is aligned with the end section 7'" of the passage 7, leading to the contact wall or wing 11 located at the free end of the trigger lever 10.
  • connection terminal 1 comprises an integrated or incorporated reset and/or clamping release means 15 able to displace the spring force loaded arm 6 from its extended position into its retracted one, against the spring force, the locking means 8, 9 providing an automatical locking of said arm 6 in its retracted position when said position is reached, a reset means 15 being associated with and acting on one or several arm(s) 6.
  • the reset means 15 consists in an electrically insulated lever mounted through a hinged link 16 onto said housing or cage 2 (the bearings can be formed on said cage 2) and comprising i) a pushing part 15" able to contact the spring loaded arm 6 over all its pivoting movement between its retracted position and its extended position and ii) a pressing part 15', in the shape of a push button for contact with a finger of a user.
  • the pushing part 15" may define a contact and gliding profile 15"' allowing the free end 6' of the spring loaded arm 6 to press against and simultaneously slip along it while pushed in its locked position ( figures 1 and 7 ).
  • the hook 8 automatically engages the anchoring slot or cutout 9, when the arm 6 is sufficiently bent by the electrically insulated lever and positioned in the right place.
  • connection terminal 1 may comprise at least two clamping arrangements 5 arranged side by side, each incorporating corresponding trigger means 10 and being associated with a respective passage or channel 7 for reception of the end portion 4 of a conductor or wire 3.
  • each one of the clamping arrangement 5 of a pair of coupled arrangements 5 can have its own separate reset means 15 acting only on the one arm 6 it is associated with.
  • a same reset means 15, such as a plastic lever hinged with the cage or housing 2 may be associated with and able to act simultaneously on the two spring loaded arms 6 of a pair of clamping arrangements 5, preferably contacting the arms 6 in a region approximately aligned with their latching means 8.
  • the pressing area of the lever on the arm 6 will be located laterally outside the region where the wire passes.
  • the invention can provide that when the clamping arrangements 5 are grouped in pairs, both arrangements 5 of each pair are preferably made from one single metal strip.
  • the housing or cage 2 may comprise an opening 2' allowing the passage of the pushing part 15" of the lever, said opening 2' being closed by said pushing part 15" and covered by the pressing part 15'.
  • the lever 15 comprises means preventing mutual engagement of the locking means 8, 9 upon actuation of said lever when a conductor or wire 3 is present in the passage 7 and clamped by the concerned arm 6.
  • the means 16' preventing mutual engagement of the locking means 8, 9 consist of means using the presence of at least one wire in the passage 7, or in at least one passage 7 in case of a same reset means 15 associated with several passages 7, to limit the displacement of the reset means 15 so that it cannot reach the position wherein an automatical mutual engagement of the locking means 8, 9 takes place.
  • the insulated pivoting lever is provided, at or near its free end opposed to it hinged end, with a projecting portion 16', such as a wall or a wing part, extending in a parallel manner to and in the same direction that the pushing part 15", the free edge of said projecting portion 16' contacting a conductor or wire 3 located within a concerned passage 7 and stopping the pivoting displacement of said lever before its pushing part 15" is able to displace the concerned spring loaded arm 6 sufficiently to cause mutual engagement of the locking means 8, 9.
  • a projecting portion 16' such as a wall or a wing part
  • FIG. 6 shows with S1 the stroke allowed to the lever (from its resting position when no pressure is applied to its pressing part 15') until the wall 16' contacts the wire 3 (or its bare end portion 4 within the insulated housing 17').
  • S2 illustrates the stroke of the lever which would be necessary to cause mutual engagement of the locking means 8, 9.
  • the invention may provide the pressure of the projecting portion 16' of the lever (preferably integrally formed with it) on a conductor or wire 3 clamped by the spring loaded arm 6 within a corresponding passage 7 causes its bare end portion 4 engaged by the arm 6, and possibly by a corresponding counterclamping means, to be released in order to allow the extraction of said considered conductor or wire 3.
  • a sufficient pressure applied by the projecting portion 16' onto the bare end portion 4 may disengage it from the notch 7" and also bent it downwards so as to release it from the grip of the spring loaded arm 6 resting against it (by it edge 6").
  • the invention also encompasses an electrical connection device 17, as a separate component or an integral part, comprising an external housing 17' made of non-conductive material.
  • said device 17 comprises at least one spring clamping connection terminal 1 as described herein before, said or each terminal 1 being possible electrically linked to a male or female plug-in socket 18, 18'.
  • FIG. 8 An example of such a device 17 is partly shown on figure 8 , wherein one double connection terminal 1 is connected through its conductive housing 2 to a pin connector 18 (top part of the device 17 on figure 8 ) and two double connection terminals 1 are connected through their conductive housing 2 to respective female plug-in clamp connectors 18' (bottom part of the device 17 on figure 8 ).
