Definitions

  • the present invention relates to a spring-loaded terminal with a busbar, which is provided for contacting an electrical conductor, in particular a stranded conductor, and with a spring, which is provided for fixing the electrical conductor in the spring-loaded terminal.
  • Such spring-loaded terminals in an embodiment as direct plug-in terminals (push-in) with a compression spring which presses the conductor against the busbar are known in various embodiments. They differ primarily because of their application, for example depending on the required current-carrying capacity of the busbar, the spring force of the clamping spring and / or their installation conditions, in particular their size. Simple assembly and inexpensive manufacture are permanent requirements for such a clamp.
  • the DE 10 2011 055919 A1 shows a spring-loaded terminal with the features a) to c) of claim 1.
  • a spring-loaded terminal is known in an embodiment as a direct plug-in terminal, in which the clamping point can be opened with a sliding sleeve acting directly on a clamping leg of a clamping spring.
  • the pamphlet US 7,997,915 B2 discloses a wire end ferrule, at one end of which a direct plug-in terminal is arranged for permanently connecting an electrical conductor.
  • the direct plug-in terminal comprises a current-carrying terminal cage for making electrical contact with the electrical conductor and a spring for fixing the electrical conductor.
  • the spring has a pivotable clamping leg which, when the electrical conductor is not inserted into the direct plug-in terminal, is positioned on a retaining edge, so that a free space is kept free for the electrical conductor and can be inserted into the terminal cage.
  • the holding means is displaced in such a way that the clamping leg is released and pivoted.
  • the pivoted clamp leg presses the electrical conductor against the clamp cage.
  • a generic prior art also shows DE 10 2004 001 202 A1 .
  • the object of the present invention is to create a spring-loaded terminal, in particular a row-mounted spring-loaded terminal, in particular for stranded conductors, in which the insertion of finely stranded conductors that are particularly flexible is significantly easier.
  • a spring-loaded terminal which comprises a busbar for contacting an electrical conductor, as well as a clamping spring for fixing the electrical conductor in the spring-loaded terminal, the clamping spring having a clamping leg which can be pivoted about a pivot axis in a pivoting direction and which is in a detent state in which it is latched on a holding means, can be pivoted by moving the electrical conductor inserted into the spring-loaded terminal into a clamping state in which it is unlocked from the holding means and presses the electrical conductor against the busbar.
  • the retaining means is arranged on a retaining spring which can be pivoted about a second pivot axis in and against a second pivot direction. By giving away the retaining spring, the retaining means can therefore be pivoted in such a way that the clamping leg disengages.
  • the retaining spring preferably has a pressure surface which furthermore preferably extends transversely to the sliding direction. It is preferred that the retaining spring can be pivoted in the second pivoting direction by pressing on the pressure surface.
  • a pressure surface at a different angle to the sliding direction is also conceivable. Arranging the pressure surface transversely to the sliding direction is advantageous because of the large contact surface for the electrical conductor in this arrangement.
  • the pressure surface is arranged below the holding means in the sliding direction.
  • the spring-loaded terminal has a sliding sleeve which serves as an insertion aid for the conductor and which significantly facilitate the insertion of such finely stranded conductors, which are particularly flexible.
  • the sliding sleeve with a sliding section slidably guided in an insertion opening of the housing and the sliding sleeve has, as an extension of the sliding section, an actuating attachment which extends to the retaining spring and which is coupled to the retaining spring at its end directly or in the area of a transverse web.
  • the spring-loaded terminal is characterized in that it comprises a restoring means which is provided for pivoting the clamping leg back.
  • the clamping leg can be swiveled back from the clamped state into the latched state by moving the restoring means against the swivel direction.
  • a conductor of the spring-loaded terminal that was previously jammed in the clamping state can be removed again in the latched state.
  • the resetting means preferably protrudes from a clamp housing of the spring-loaded clamp. This makes it very easily accessible and very easy to push in the sliding direction.
  • the handling of the spring-loaded terminal can therefore be carried out in the same way for solid conductors and stranded conductors and is very simple.
  • the restoring means is clamped in the clamped state between the clamp leg and the clamp housing in the latter, so that it does not come loose from the clamp housing.
  • the clamping spring, the busbar and / or the retaining spring are preferably produced as stamped and bent parts from sheet metal, preferably from strip material, since this can be done inexpensively with conventional methods.
  • the busbar is preferably made of a material with good electrical conductivity, in particular a copper-containing metal.
  • the clamping spring and retaining spring are preferably made from a material with good spring properties.
  • Fig. 2 shows a spring-loaded terminal 1, here a lined-up terminal, with a busbar 2 for contacting an electrical conductor, a clamping spring 3 acting as a compression spring, which is provided for clamping the electrical conductor 6 in the spring-loaded terminal 1, and with a retaining spring 4.
  • the busbar 2, the clamping spring 3 and the retaining spring 4 are arranged in a terminal housing 12, which is preferably made from an electrically insulating material, in particular from a plastic.
  • An insertion opening 11 for inserting the electrical conductor 6 is provided in the terminal housing 12.
  • the electrical conductor 6 shown has an electrically insulating sheath 62 which is stripped above an open end 63 of the electrical conductor 6, so that a wire 61 of the electrical conductor 6 is visible.
  • the clamping spring 3 has a clamping leg 32 that can be pivoted about a pivot axis 8 in a pivoting direction 81, as well as a retaining leg 31 with which it is supported in a simple and secure manner on the terminal housing 12 (in particular made of plastic), especially when the clamping leg 32 is pivoted.
  • One metallic clamping cage is not provided here, but is optionally conceivable.
  • the retaining leg 32 and the clamping leg 32 are preferably connected to one another via a bend. An advantageous support contour of the terminal housing engages in this bend, through which the axis of rotation 8 passes here and which also serves to limit the movement.
  • the clamping leg 32 has an open end 33. In the latching state R, it is latched with its open end 33 against its restoring force with the holding means 41.
  • the retaining spring 4 can be pivoted about a second pivot axis 9 in and against a second pivot direction 91. When the retaining spring 4 is given away, the retaining means 41 is pivoted with it against the restoring force of the retaining spring 4. As a result, the position of the holding means 41 shifts about the second pivot axis 9, so that the open end 33 of the clamping leg 32 is unlocked.
  • the retaining spring 4 In order to pivot the retaining spring 4 in the second pivot direction 91, it has a pressure surface 42.
  • the pressure surface 42 is provided transversely to the sliding direction S or conductor insertion direction S. By pressing on the pressure surface 42, the retaining spring 4 can be pivoted in the second pivoting direction 91.
  • a free space is formed between the clamping spring 3 and the busbar 2, in which the electrical conductor 6 in the latched state R of the clamping leg 32 can be freely displaced in and against the sliding direction S.
  • the spring-loaded terminal 1 also includes a return means 5.
  • the return means 5 is displaceable in and against the sliding direction S. It is provided for pivoting back the clamping leg 32 against the pivoting direction 81.
  • the clamping leg 32 can be pivoted back from the clamping state K into the latching state R by moving the restoring means 5 against the pivoting direction S, so that its open end 33 locked again with the holding means 41.
  • An electrical conductor 6, which was previously jammed in the spring-loaded terminal 1 in the clamping state K, can then be removed from the spring-loaded terminal 1 in the latched state R.
  • the restoring means 5 is arranged in the latched state R between the clamping spring 3 and the electrical conductor 6. In the clamped state K, it is arranged above the clamp leg 32 in the sliding direction S. Therefore, when the clamping leg 32 is in the clamped state K, the restoring means 5 acts directly on the clamping leg 32 when it is moved in the sliding direction S, so that the displacement path required to pivot the clamping leg 32 back is small.
  • the resetting means 5 protrudes from a terminal housing 12 of the spring-loaded terminal 1 in the clamping state K. This makes it very easily accessible and very easy to push in the sliding direction S. To actuate the restoring means, it has an actuation groove which simplifies actuation with a tool such as a screwdriver.
  • the restoring means 5 is clamped between the clamp leg 32 and the clamp housing 12 in the latter, so that it does not become detached from the clamp housing 12.
  • the Fig. 2 (a) shows the clamping spring 3 in the latching state R of the clamping leg 32.
  • the electrical conductor 6 is still arranged outside the spring-loaded terminal 1. It can be seen that the open end of the clamping leg is latched onto the holding means, which is designed here as an edge. The free space 13 between busbar 2 and clamping leg 32 can also be clearly seen.
  • the Fig. 2 (c) shows the electrical conductor 6 jammed in the spring-loaded terminal 1.
  • the clamping leg 32 is pivoted in the pivoting direction 81 about the pivot axis 8 and its open end 33 presses the wire 61 of the electrical conductor 6 against the busbar 2.
  • the clamping leg 32 is the Resetting means 5 presses against the sliding direction S when pivoting in the pivoting direction 81.
  • the restoring means 5 moves against the sliding direction S, so that it protrudes from the terminal housing 12 and is easily accessible.
  • the clamping leg 32 also has an angle 321 to the sliding direction S. It is conceivable to choose this in such a way that the restoring means 5 is pressed against the terminal housing 12 in the clamping state K and is clamped in a self-locking manner.
  • the electrical conductor 6 can be released by moving the restoring means 5, starting from this clamping state K, in the sliding direction S until the open end 33 of the clamping leg 32 engages with the holding means 41 in the latching state R again.
  • the subject of Fig. 2 - to which additional reference is made - is in the Fig. 1 (a - e) advantageously supplemented by a sliding sleeve 7, which serves as an insertion aid for the conductor.
  • This sliding sleeve 7 is particularly advantageous when a conductor 6 with a very finely stranded core or core or strand arrangement 61 is used.
  • the sliding sleeve 7 is guided displaceably with a sliding section 71 in the insertion opening 11 of the housing 12. Both the sliding sleeve 7 and the insertion opening 11 have corresponding sliding contours in this area, so that the sliding sleeve 7 with a sliding section can easily be moved into the insertion opening 11.
  • the sliding contours can have corresponding rectangular, for example square, cross-sections (see FIG Fig. 1d ) but also have other, for example cylindrical, cross-sections.
  • the sliding sleeve 7 also has its own lead-through opening 72, into which the electrical conductor 6, which has been stripped in its end region, can be inserted.
  • This feed-through opening 72 tapers in such a way that, in the case of conductors 6 of a suitable pressure gauge whose insulation is (slightly) larger than the diameter of the feed-through opening 72 in the narrowed section, the wire arrangement 62, but not the insulation or sheathing 61 in the inserted state can protrude from the sliding sleeve 7 in the sliding direction S. Rather, when the conductor is in the inserted state, the sheath 61 rests on the tapering area 73 in the sliding direction and can thus advance the sliding sleeve in the sliding direction S when the conductor 6 continues to move in the sliding direction S.
  • the sliding sleeve also has a web-like actuating projection 74 as an extension of the sliding section 71, which extends up to the retaining spring 4 and which is coupled to the retaining spring 4 at its end directly or in the area of a transverse web 75.
  • this coupling is realized in that one end of the retaining spring is in a slot 76 of the actuating extension 74, here the crosspiece 75, engages.
  • the other end of the retaining spring 4 with the retaining means is preferably fixed in a slot in the housing 12.
  • the retaining spring 4 can be deflected in this way in the sliding direction S at its end coupled to the actuating shoulder 74.
  • the insulation 61 comes to rest on the tapering area 73. In this state, the wire arrangement or strand arrangement 62 protrudes from the sliding sleeve 7 in the sliding direction or in the direction of the contact point to be formed.
  • the sheathing or insulation 61 pushes the sliding sleeve 7b further forward in the sliding direction S. This deflects the retaining spring 4 coupled to the actuating attachment 71, which finally releases the clamping spring 3 when the conductor 6 with the sliding sleeve 7 is inserted sufficiently wide, so that it can relax and contact the line core.
  • Opening the terminal point can be done in the same way as Fig. 2 take place with a restoring means 5. This opening is in Fig. 1 (e) indicated.
  • the insertion opening 61 preferably has a step as a stop for the sliding means in the sliding direction S in order to define the maximum sliding path.
  • the spring-loaded terminal 1 of the Fig. 3-4 differ from the spring-loaded terminal 1 of the Fig. 1 in particular and among other things by the design of the retaining spring 104.
  • a sliding sleeve is not shown in this embodiment, but could be supplemented.
  • Each spring-loaded terminal of the Fig. 3-4 can therefore be provided with a sliding sleeve, which is preferably in the manner of Fig. 1 is designed.
  • Fig. 3 shows a spring-loaded terminal 101, here a lined-up terminal, with a busbar 102 for contacting an electrical conductor, a clamping spring 103 acting as a compression spring, which is provided for clamping the electrical conductor (not shown here) in the spring-loaded terminal 101, and with a retaining spring 104
  • the sliding sleeve to be supplemented is not shown.
  • the busbar 102, the clamping spring 103 and the retaining spring 104 are in a terminal housing in the manner of Fig. 2 arranged from the in Fig. 3 only a basic body that is in Fig. 3 is not shown and which is preferably made of an electrically insulating material, in particular a plastic. An insertion opening for inserting the electrical conductor is again provided in the terminal housing. It will refer to the relevant explanations too Fig. 2 referenced.
  • the clamping spring 103 has a clamping leg 132 which can be pivoted about a pivot axis 108 in a pivoting direction 181, as well as a holding leg 131 with which it is supported in a simple and secure manner on a metallic clamping cage, which is here with the busbar, especially when the clamping leg 132 is pivoted 10 is formed in one piece.
  • the holding leg 131 and the clamping leg 132 are preferably connected to one another via a bend 130.
  • An advantageous support contour of the terminal housing 112 engages in this bend 130, through which the axis of rotation 108 penetrates here and which also serves to limit the movement (see FIG Fig. 2 ).

  • the resetting means 105 is displaceable in and against the sliding direction 107. It is provided to pivot the clamping leg 132 back against the pivoting direction 181.
  • the clamping leg 132 can be swiveled back from the clamping state K into the latching state R by moving the restoring means 105 against the pivoting direction 107, so that its open end 133 latches again with the holding means 141.
  • An electrical conductor 106 which was previously jammed in the spring-loaded terminal 101 in the clamping state K, can then be removed from the spring-loaded terminal 101 in the latched state R.
  • the restoring means 105 is arranged in the latching state R between the clamping spring 103 and the electrical conductor. In the clamped state K, it is arranged above the clamp leg 132 in the sliding direction 107. Therefore, when the clamping leg 132 is in the clamped state K, the restoring means 105 acts directly on the clamping leg 132 when it is moved in the sliding direction 107, so that the displacement path required to pivot the clamping leg 132 back is small.
  • the restoring means 105 protrudes from a terminal housing 112 of the spring-loaded terminal 11 in the clamping state K. This makes it very easily accessible and very easy to push in the sliding direction 107.

It can be seen that the open end 133 of the clamping leg 103 in this embodiment of the spring-loaded terminal 101 without the inserted conductor 106 rests on a latching lug 121 of the busbar 102.
  • the bus bar 102 of this embodiment is part of a clamping cage 120, e.g. is bent in a U shape.
