Definitions

  • the invention relates to a connection terminal arrangement for connecting at least one electrical conductor.
  • connection terminal arrangements usually have a busbar against which the electrical conductor to be connected can be pressed by means of a clamping spring in order to form electrical contact.
  • the clamping spring is usually designed as a leg spring which has a holding leg and a clamping leg which are connected to one another via an arcuate section.
  • the holding leg is usually positioned in a stationary manner, whereas the clamping leg can be pivoted relative to the holding leg in order to be able to clamp the conductor to be connected.
  • the retaining leg is supported against the housing surrounding the busbar and the clamping spring or against a clamping cage surrounding the busbar and the clamping spring, in that the retaining leg rests flat against a housing wall or a clamping cage wall.
  • the invention is based on the object of providing a connection terminal arrangement in which the positioning of the clamping spring can be improved.
  • connection terminal arrangement has a busbar, at least one clamping spring, which has a retaining leg for holding the clamping spring and a clamping leg for clamping the at least one conductor to be connected against the busbar in a connected state, and a clamping spring retaining element on which the at least one clamping spring is connected its retaining leg is held in a latching manner, the clamping spring retaining element being formed in one piece with the busbar.
  • the clamping spring is held directly on the busbar and thus directly on the via its retaining leg Busbar is attached.
  • a clamping spring holding element is formed on the busbar, on which the holding leg of the clamping spring can be held and fastened in a latching manner, that is to say via a latching engagement or a latching connection.
  • the clamping spring retaining element is formed in one piece with the busbar, so that the clamping spring retaining element can be formed directly when the busbar is produced or shaped.
  • the one-piece design ensures that the clamping spring retaining element is positioned in a fixed position relative to the busbar. In this way, the clamping spring can also be held in a secure and fixed position relative to the busbar.
  • the clamping spring retaining element is preferably positioned relative to the busbar in such a way that the clamping spring retaining element can extend at a 90 ° angle from a surface of the busbar on which the at least one conductor to be connected rests in the connected state.
  • the clamping spring holding element thus preferably protrudes from the busbar, so that assembly of the clamping spring on the clamping spring holding element can be facilitated.
  • the clamping spring can be placed in a simple manner on the clamping spring holding element in such a way that it can come into locking engagement with the clamping spring holding element.
  • the spring clip element can be stuck vertically away from the power rail due to the 90 ° angle.
  • the clamping spring retaining element thus preferably projects in the direction in which the conductor is also connected.
  • the clamping spring holding element can preferably be designed or produced in that the clamping spring holding element can be punched free from the busbar or from the material of the busbar and then sheared up from a plane spanned by the busbar.
  • the clamping spring retaining element can thus also be punched out at the same time, so that this can be done in one work step.
  • the punched-out spring clip element can then be bent up or sheared up until it can extend at a 90 ° angle to the surface of the busbar or to a plane spanned by the busbar.
  • the busbar is preferably designed in the form of a web or in the form of a plate which extends only in one plane, the clamping spring retaining element preferably being bent or sheared out of this plane.
  • the busbar can be made from an endless belt, for example.
  • several busbars formed in one piece with one another and thus also several such clamping spring holding elements can be provided on this endless belt, so that several clamping springs can also be arranged in a row next to one another.
  • the busbar it is also possible, however, for the busbar to be designed in the form of a single rail on which only one clamping spring retaining element is also designed.
  • the clamping spring retaining element can have at least one latching lug for lockingly holding the retaining leg of the at least one clamping spring.
  • the latching lug can preferably be wedge-shaped so that it can have an inclined surface which can serve as a guide surface for positioning the retaining leg on the clamping spring retaining element.
  • the retaining leg can preferably have a recess or a window-like opening into which the latching lug can hook or through which the latching lug can penetrate in order to be able to form a latching engagement between the clamping spring retaining element and the retaining leg of the clamping spring.
  • the connecting terminal arrangement can then have a first clamping spring and a second clamping spring, the first clamping spring being held in a latching manner on the clamping spring holding element via its holding leg and the second clamping spring being held in a latching manner on the clamping spring holding element via its holding leg.
  • the connection terminal arrangement enables two conductors to be connected. Because the two clamping springs can be held on one and the same clamping spring retaining element, a particularly compact arrangement of the clamping springs and thus the entire connection terminal arrangement is possible.
  • the clamping spring retaining element then preferably has a first latching lug for holding the retaining leg of the first clamping spring and a second latching lug for holding the retaining leg of the second clamping spring.
  • the latching lugs are preferably designed to be directed away from one another, so that the two clamping springs can be arranged in a line along the length of the busbar, the clamping spring retaining element is preferably arranged between the two clamping springs.
  • the two latching lugs are preferably shaped together in such a way that the clamping spring holding element forms a mushroom shape.
  • the latching lugs can preferably each be designed in a wedge shape so that they can each have an inclined surface which can serve as a guide surface or guide bevel for positioning the retaining leg of the respective clamping spring on the clamping spring retaining element.
  • the clamping spring retaining element can preferably have a web, wherein the first latching lug can be formed on a first side surface of the web and the second latching lug can be formed on a second side surface of the web opposite the first side surface, so that the web between the retaining leg of the first clamping spring and the retaining leg of the second clamping spring can be arranged for spaced positioning of the first clamping spring to the second clamping spring.
  • the web of the clamping spring retaining element can thus ensure that the two clamping springs are arranged at a distance from one another, so that no contact or touching can take place between the two clamping springs. Mutual influencing of the two clamping springs arranged on the clamping spring holding element via their clamping spring forces can thus be avoided.
  • the retaining legs of the two clamping springs are therefore preferably not in contact with one another, but rather the retaining legs of the two clamping springs are each preferably in contact with the web of the clamping spring retaining element.
  • Fig. 1 shows a connection terminal arrangement 100 for connecting an electrical conductor, not shown here.
  • connection terminal arrangement 100 has a busbar 10 which is designed in the form of a bar or a web. Furthermore, the connection terminal arrangement 100 has a clamping spring 11, by means of which the conductor to be connected can be clamped against the busbar 10 in order to be able to form an electrical contact.
  • the clamping spring 11 is designed as a leg spring and has a retaining leg 12 and a clamping leg 13, the retaining leg 12 being connected to the clamping leg 13 via an arcuate section 28.
  • the clamping leg 13 can be pivoted relative to the holding leg 12 in order to be able to clamp a conductor to be connected against the busbar 10.
  • the retaining leg 12, on the other hand, is positioned in a stationary manner, with the retaining leg 12 being held on a clamping spring retaining element 14 for this purpose.
  • the clamping spring retaining element 14 is formed in one piece with the busbar 10 by the clamping spring retaining element 14 being formed from the material of the busbar 10.
  • the clamping spring retaining element 14 is arranged at a 90 ° angle to a surface 15 of the busbar 10, to which the conductor to be connected in one connected and clamped state.
  • the clamping spring retaining element 14 thus protrudes from the busbar 10 in that the clamping spring retaining element 14 extends perpendicular to the busbar 10.
  • the clamping spring retaining element 14 has a web 16 and one or two latching lugs 17, 18 which are integrally formed on the web 16. With a first end 19 of the web 16, the clamping spring retaining element 14 is formed in one piece with the busbar 10. The two latching lugs 17, 18 are formed on a second end 20 of the web 16 opposite the first end 19. In the embodiment shown here, two locking lugs 17, 18 are formed on the web 16, but it is also possible that only one locking lug 17, 18 is formed on the web 16.
  • a clamping spring 11 can be held in a latching manner on the clamping spring holding element 14 via the locking lugs 17, 18.
  • the clamping spring 11 has a window-like opening 21 on its retaining leg 12, through which a locking lug 17, 18 can penetrate in order to be able to hold the clamping spring 11 in a locking manner on the clamping spring retaining element 14.
  • the latching lugs 17, 18 are each wedge-shaped so that they each have a guide bevel 22, 23, which can facilitate mounting of the clamping springs 11 on the latching lugs 17, 18 and thus on the clamping spring retaining element 14. Due to the latching lugs 17, 18 and the guide bevels 22, 23 of the latching lugs 17, 18, the clamping spring retaining element 14 has a mushroom shape.
  • the clamping spring retaining element 14 is formed in the middle of the length L of the busbar 10 on the busbar 10.
  • connection terminal arrangement 100 has two clamping springs 11, then two conductors can also be connected in the connection terminal arrangement 100.
  • One of the two latching lugs 17 is formed on a first side surface 24 of the web 16 and the other latching lug 18 is formed on a second side surface 25 of the web 16 opposite the first side surface 24, so that the web 16 is positioned between the retaining legs 12 of the two clamping springs 11 , as in Fig. 2 can be seen.
  • the web 16 or the clamping spring retaining element 14 can thus accommodate the two clamping springs 11 keep at a distance from one another so that they do not rest against one another at any point and thus no mutual influence of the two clamping springs 11 can take place.
  • Fig. 3 shows an embodiment in which several busbars 10 are integrally connected to one another in the form of an endless belt 26, so that several clamping spring retaining elements 14 are arranged in a row one behind the other, on each of which two clamping springs 11 can be held in a latching manner via their retaining legs 12.
  • Fig. 4 and 5 show the production of busbars 10 with corresponding clamping spring retaining elements 14, with a plurality of busbars 10 in the form of an endless belt 26 also being formed in one piece with one another.
  • the clamping spring retaining elements 14 are first punched free from the material of the busbars 10. After punching free, the clamping spring retaining elements 14 are sheared up from the plane E formed by the busbars 10 until they are aligned at a 90 ° angle to the surface 15 of the busbar 10, as in FIG Fig. 5 can be seen.
  • the formation of the clamping spring retaining element 14 in this form by punching free and shearing up takes place regardless of whether the busbars 10 are an endless belt or a single rail, as shown in FIG Fig. 1 is shown, formed or manufactured.
  • connection terminal arrangement 100 can have an insulating material housing 27, within which the busbar 10 and the clamping springs 11 can be arranged.
  • the clamping springs 11 are first placed in the insulating housing 27. Then the busbar 10 is inserted from below in the assembly direction M with its clamping spring retaining element 14 between the two clamping springs 11 or between the two retaining legs 12 of the clamping springs 11 in order to fasten the clamping springs 11 to the clamping spring retaining element 14 and to close the busbar 10 in the insulating material housing 27 position.
  • the busbar 10 is first positioned together with the clamping spring retaining element 14 in the insulating material housing 27 and then the clamping spring 11 is slipped onto the clamping spring retaining element 14 from above in the assembly direction M, as shown by the guide and the double representation of the clamping spring 11 in Fig. 7 is indicated.
  • connection terminal arrangement 100 thus differs in the two in FIG Fig. 6 and 7th embodiments shown.
