Definitions

  • a connection terminal with a spring-loaded terminal connection and an actuating lever is known.
  • the actuating lever is pivotally mounted with its axis of rotation behind the terminal point below the clamping spring, as seen in the conductor insertion direction.
  • An actuating tab is bent at the free end of the clamping leg, which works together with an actuating finger of the actuating lever to open the spring-loaded terminal connection.
  • DE 19 84 159 U discloses a clamping device for connecting electrical cables with a U-shaped sheet metal body that has a recess for a lever and a clamping spring.
  • the lever is arranged behind the electrical conductor to be clamped in the conductor insertion direction and consists of a U-shaped sheet metal body and a lever arm that is installed in a recess in the sheet metal body.
  • EP 1 605 547 A1 discloses a connection terminal with a double spring. To actuate each spring element, an actuating lever is pivotably mounted above a busbar section.
  • EP 1 641 079 A1 shows a connection terminal in which a pivoting operating lever is built into the insulating housing above the conductor insertion opening and the electrical conductor to be connected.
  • EN 20 2009 002 240 U1 describes an electrical connection terminal with an operating tool that is pivotably mounted in the insulating housing far outside the electrical conductor to be connected.
  • DE 29 22 477 A1 discloses a terminal block with a busbar section that has a roof-shaped contact surface for guiding an electrical conductor.
  • An actuating lever is pivotably mounted on the busbar section next to an adjoining surface.
  • EP 0 821 433 A1 discloses a connection terminal with a rod-shaped actuating lever which is pivotably arranged in the insulating housing between the inserted electrical conductor and the clamping leg of the clamping spring.
  • JP 2004 319394 A discloses a connection terminal with an actuating lever, each of which has an actuating plunger for a clamping spring arranged to the right and left of a pivot bearing arm. An electrical conductor will then pass laterally past one of these actuating arms to the clamping point, with a free space between the conductor insertion opening and the clamping point.
  • EP 1 081 790 A1 shows a spring terminal for connecting electrical conductors.
  • the electrical conductor is guided along a side wall of a busbar cage to a terminal point.
  • An operating lever is pivotably mounted above the busbar section.
  • connection terminal that is as small as possible with a spring-loaded terminal connection and actuating lever, which is also improved with regard to the force effect of the actuating lever on the connection terminal and the conductor guide.
  • connection terminal with the features of claim 1.
  • the actuating lever is arranged so as to be pivotable in an associated conductor insertion opening or the extension of the conductor insertion opening that continues in the conductor insertion direction to the clamping point, with the rotation axis of the actuating lever being arranged transversely to the conductor insertion direction in the associated conductor insertion opening or the extension of the conductor insertion opening that continues in the conductor insertion direction to the clamping point.
  • the actuating lever has two opposing lateral boundary walls for guiding an electrical conductor that is inserted into a conductor insertion opening in the conductor insertion direction to an associated clamping point.
  • the rotation of the operating lever takes place in the area of the terminal point or in the space in front of it.
  • This has the advantage that the operating lever can be accommodated in the insulating housing in a very space-saving manner and at the same time serves as the wall of the conductor entry channel for guiding an electrical conductor.
  • the operating lever thus replaces part of the guide wall for an electrical conductor in the conductor entry opening.
  • the at least one actuating lever is arranged adjacent to an associated busbar section forming the clamping point in such a way that the actuating lever is arranged in the space between the plane spanned by the busbar section and the plane parallel to this, defined by the clamping edge of the clamping spring that is fully opened when the actuating lever is pivoted.
  • the actuating lever is preferably positioned below the busbar section in the conductor insertion direction slightly in front of or directly below the clamping point.
  • the busbar in the section that forms the clamping point defines a first plane, regardless of any elevations for a contact edge, to which a second imaginary plane is spanned.
  • This second plane is spaced from the plane of the busbar section in such a way that the clamping edge of an opened clamping spring touches this plane.
  • the space between the planes forms the preferred space in which the actuating lever should be in order to provide an extremely compact, mechanically stable connection terminal.
  • At least one actuating lever is inserted into a cutout of the busbar piece that is adjacent to a clamping section of the associated busbar piece.
  • the actuating lever then uses an actuating section to actuate an actuating tab that is arranged next to the clamping section of the clamping spring, viewed across the width of an associated clamping spring, in order to open the clamping spring.
  • the cutout on a side edge of the busbar piece makes it possible to accommodate the actuating lever in a space-saving manner.
  • an actuating tab Viewed across the width of the busbar piece and the associated clamping spring, an actuating tab is then exposed on the clamping section of the clamping spring below this cutout, which is then acted upon by the actuating section of the actuating lever when the actuating lever is pivoted in order to open the clamping spring.
  • the electrical contacting of an electrical conductor then takes place adjacent to this cutout of the busbar piece or, viewed across the width, adjacent to the actuating tab by the clamping section of the clamping spring and a preferably forward contact edge of the busbar piece.
  • the actuating tab is preferably freed from the clamping spring, e.g. by punching or cutting, and protrudes obliquely from the clamping section of the clamping spring.
  • the at least one clamping spring is preferably designed as a U-shaped clamping spring, the free clamping section of which points obliquely in the direction of an associated busbar section.
  • a U-shaped clamping spring With the help of such a U-shaped clamping spring, a direct clamping of an electrical conductor is possible without first opening the clamping spring with the associated operating lever. This is also known as direct plug-in technology.
  • the at least one actuating lever has an actuating arm that extends on the underside or the top of the connection terminal in the conductor insertion direction or in the opposite direction.
  • the connection terminal that are as compact as possible, combinations are particularly conceivable in which the actuating arms of the actuating levers extend alternately in the conductor insertion direction and in the opposite direction, or alternately extend on the underside and top in the same directions or alternately in opposite directions.
  • Figure 1 shows a connection terminal 1 with an insulating housing 2, in which at least one pair of opposing spring clamp connections 3a, 3b are installed.
  • the spring clamp connections 3a, 3b each have a U-shaped clamping spring 4 and a common busbar section 5.
  • Each spring-loaded terminal connection 3a, 3b provides a clamping point by means of a clamping section 6 formed at the free, movable end of the clamping spring and in particular by means of the clamping edge at the free end of the clamping spring 4 and at the busbar section 5a opposite the clamping section 6.
  • an associated conductor insertion opening 7 is made in the insulating housing for each spring-loaded terminal connection 3a, 3b.
  • the conductor insertion opening 7 has a diameter that is adapted to the largest possible permissible cross-section, including the insulating sheath, of an electrical conductor.
  • each spring-force clamp connection 3a, 3b has an actuating lever 8 with an actuating section 9 and an adjacent actuating arm 10 extending in a longitudinal direction.
  • the left operating lever 8a is shown in the closed position and the right operating lever 8b is shown in the open position of the clamping spring. It can be seen that the operating levers 8a, 8b are pivoted by approximately 90° from the closed position to the open position. It is clear that the operating lever 8a with its operating section 9 and in particular the axis of rotation D about which the operating lever 8a, 8b is pivotably mounted in the insulating housing 2 of the connection terminal, is arranged in the space of the associated conductor entry opening 7 or in the conductor entry direction L to the clamping point in the further extension of the conductor entry opening 7. However, the axis of rotation D is still positioned in front of the clamping point when viewed in the conductor entry direction L and is in no way behind the clamping section 6 of the clamping spring 4 when viewed in the conductor entry direction L.
  • an actuating tab 11 is exposed next to the clamping section 6 and protrudes obliquely from the clamping section 6.
  • An eccentric-like, protruding contour of the actuating section 9 of the associated actuating lever 8a, 8b acts on this actuating tab 11 at least partially during the movement when the actuating lever 8a, 8b is pivoted from the closed position (left actuating lever 8a) to the open position (right actuating lever 8b). In this way, the clamping section 6 of the clamping spring 4 is moved away from the adjacent busbar section 5a forming the clamping point in order to open the clamping spring 4.
  • actuating levers 8a, 8b are accommodated in recesses in the insulating housing 2 for receiving a part of the actuating arm 10.
  • the actuating arm 10 protrudes in the closed position (left actuating arm 8a in Figure 1 ) opposite to the conductor insertion direction L at the respective front side of the associated conductor insertion opening 7 from the insulating housing 2.
  • an embodiment is also conceivable in which the actuating arm 10 is rotated by 180° and points in the conductor insertion direction L in the closed position.
  • This is particularly conceivable for a connection terminal in which only one spring-loaded terminal connection is present over the length of the connection terminal shown in the conductor insertion direction L and several spring-loaded terminal connections in the direction of view of the Figure 1 are arranged distributed across the width.
  • connection terminal 1 In the connection terminal 1 shown, it is conceivable that not only one such pair of spring-loaded terminal connections 3a, 3b with associated actuating levers 8a, 8b is provided, but rather several such arrangements are arranged next to one another across the width of the connection terminal as viewed in the direction of view.
  • a bridge insertion opening 12 is provided on the top of the insulating housing, which is open to the top of the insulating housing 2.
  • the bridge insertion opening 12 opens into a bridge terminal connection formed by a material tab 13 of the busbar 5 and a downwardly bent end 14 of a clamping spring 4.
  • busbars 5 arranged next to one another are electrically connected to one another with associated spring-loaded terminals 3a, 3b.
  • Such bridges have at least two parallel comb teeth, which are electrically connected to one another via a web running transversely thereto. At least this transverse web can be surrounded by an insulating material sheath in a manner known per se.
  • the insulating housing 2 is constructed in two parts and has a lower part 2a onto which an upper part 2b is snapped.
  • locking lugs 16 of the lower part 2a engage in associated locking openings 17 of the upper part 2b.
  • Figure 2 shows a perspective view of a spring-loaded clamp connection 3, which is formed from a U-shaped clamping spring 4 and a busbar section 5a.
  • the busbar section 5a forming the clamping point has a clamping projection 18 at its free end, by means of which a defined contact surface for an electrical conductor is created with a reduced area. The clamping force of the clamping spring 4 is then concentrated via the electrical conductor onto this clamping surface defined by the clamping projection 18, so that the surface pressure is increased compared to a planar contact surface.
  • the free end of the busbar section 5a forming the clamping point is angled upwards in order to provide a guide for an electrical conductor to the clamping edge 18.
  • the busbar section 5a forming the clamping point has a cutout 19 in the form of a depression laterally adjacent to the clamping edge 18, into which the actuating section 9 of the actuating lever 8 is inserted.
  • the actuating tab 11 is free from the clamping section 6 of the clamping spring 4 and extends in the direction of the conductor insertion direction L.
  • the side wall of the actuating section 9 of the actuating lever 8 forms a lateral boundary wall for an electrical conductor introduced to the clamping point, which is used to guide the electrical conductor to the clamping point.
  • the busbar 5 is folded over laterally in such a way that a support surface 20 for supporting a contact leg 21 of the clamping spring 4 is created at a distance and parallel to the busbar section 5a forming the clamping point.
  • Figure 3 omits a perspective view of the spring clamp connection 3 with actuating lever 8 Figure 2 from the other side.

  • the pivot pin 22 is provided to be inserted into a corresponding opening or recess (not shown) in the insulating housing of the connection terminal 1.
  • the actuating lever 8 is thus rotatably mounted on one side in the insulating housing 2 by the pivot pin 22 serving as a bearing.

  • clamping spring 4 is formed in the form of a U-shaped clamping spring with a contact section 21, an adjoining spring arch 23 and the adjoining clamping section 6 extending approximately in the direction of the contact leg 21.
  • Figure 4 shows a variant of the connection terminal 1 in a reduced side sectional view. It is clear that the left operating lever 8a for the left spring clamp connection protrudes upwards from the top of the insulating housing.
  • the right operating lever 8b for the right spring clamp connection 3b is arranged in a mirror image such that it protrudes from the bottom of the insulating housing 2.
  • connection terminals in which there is only one spring clamp connection over the length of the connection terminal and not, as in the embodiments according to Figure 1 and 4 two spring clamp connections 3a, 3b arranged one behind the other are provided.
  • several such spring clamp connections 3a are advantageously provided across the width, ie in the direction of view of the Figure 4 arranged one behind the other.
  • the actuating levers 8 protrude alternately across the width at the top and bottom.
  • a variant is also conceivable in which the actuating arms 10 protrude alternately from the rear or front side on the one hand in the conductor insertion direction and, in the case of the adjacent spring-loaded terminal connection 3, opposite to the conductor insertion direction L.

  • the clamping edge lies on the busbar section 5a.
  • the clamping spring 4 has actuating tabs 11 on both sides of the clamping section 6.
  • connection terminal 1 An embodiment of the connection terminal 1 is also conceivable in which two spring clamp connections 3 lying next to each other are electrically connected to each other and two or three pairs of such electrically connected spring clamp connections 3 are provided. This means that two conductors for a single-phase power supply connection with the connections L (phase), N (neutral conductor) and PE (earth) can each be connected to each other, so that a mains connection terminal is formed.
  • actuating levers 8 are arranged next to the clamping points, i.e. next to the busbar section 5a and the clamping section 6 immediately behind the end of the conductor insertion opening 7 formed in the insulating housing 2.
  • the actuating sections 9 of the actuating levers 8 form a continuation of the wall of the respective conductor insertion opening 7 in order to guide an electrical conductor to the clamping point.
