Definitions
- the invention relates to a connection arrangement for connecting an electrical conductor, which has a current bar, a clamping spring, which has a holding leg and a clamping leg, and a pivotably mounted actuating lever, by means of which the clamping leg of the clamping spring can be transferred into an open position and/or a clamping position.
- clamping spring In the case of lever clamps, where the clamping spring can be actuated using an operating lever, a torque is created on the clamping spring when the operating lever acts on the clamping leg of the clamping spring, which can easily cause the clamping spring to shift or tilt.
- the clamping spring is often supported with its holding leg against a housing made of an insulating material, which, however, does not allow the torque forces acting on the clamping spring to be absorbed.
- the invention is therefore based on the object of providing a connection arrangement in which the risk of displacement or tilting of the clamping spring can be avoided.
- connection arrangement according to the invention is characterized in that the clamping spring is held on the current bar via its holding leg.
- the clamping spring is no longer held on the housing, but on the current bar.
- the clamping spring can now be held on a metal material that does not give way under stress, so that the clamping spring can be held on the current bar and thus the clamping spring within the connection arrangement in a way that is secure against twisting or tilting.
- the torques acting on the clamping spring by the actuating lever can therefore be absorbed by the current bar.
- the holding leg can be held or attached to the current bar in a detachable manner.
- the current bar can have a receiving pocket in which the holding leg of the clamping spring can be held. The holding leg can be inserted into the receiving pocket at least in part so that the holding leg can be held within the receiving pocket.
- the receiving pocket can be formed by folding the current bar or part of the current bar.
- the receiving pocket can have a free space forming an interior into which the clamping spring can be immersed with its holding leg.
- the receiving pocket enables the clamping spring to be held on the current bar in a stable and twist-proof manner by immersing the holding leg of the clamping spring in the interior of the receiving pocket.
- the holding leg can be pushed or plugged into the receiving pocket, which enables the clamping spring to be mounted on the current bar quickly and easily.
- the current bar can be shaped in such a way that the current bar can have a clamping section for clamping the conductor to be connected and a holding section extending at an angle to the clamping section, wherein the receiving pocket can be formed on the holding section.
- the conductor to be connected In the area of the clamping section, the conductor to be connected is clamped by means of the clamping leg against the current bar in the clamping position of the clamping leg.
- the conductor to be connected is preferably not clamped on the holding section.
- the holding section can be designed at an angle to the clamping section.
- the holding section can preferably extend at a 90° angle from the clamping section of the clamping spring.
- the receiving pocket can be formed by folding the current bar material on the holding section.
- the holding section can have a first leg and a second leg extending at an angle to the first leg, so that the holding section itself can be designed at an angle.
- the second leg can preferably extend at an angle between 90° and 120° to the first leg.
- the first leg of the holding section can directly adjoin the clamping section, so that the first leg of the holding section can extend between the clamping section and the second leg of the holding section.
- the second leg of the holding section then does not directly adjoin the clamping section, but is arranged at a distance from the clamping section.
- the receiving pocket can preferably be formed on the leg of the clamping section.
- the receiving pocket can preferably have a U-shape.
- the receiving pocket can encompass the holding leg inserted into the receiving pocket.
- the receiving pocket can have two opposing side walls, between which the holding leg of the clamping spring can be arranged. The holding leg can thus rest with its top and bottom on the two side walls of the receiving pocket and be supported thereby, whereby twisting or tilting of the holding leg and thus the clamping spring within the receiving pocket can be reliably prevented.
- the holding leg can have a fastening section for fastening the holding leg to the receiving pocket, wherein the fastening section can have a U-shape, by means of which the fastening section can clamp around the receiving pocket.
- the holding leg In the area of the fastening section, the holding leg can be held on the receiving pocket in order to fasten the clamping spring to the current bar.
- the fastening section can preferably be formed at a free end of the holding leg of the clamping spring.
- the U-shape can be formed in such a way that it has two web-shaped projections extending transversely to the longitudinal direction of the holding leg, which are spaced apart from one another and run parallel to one another. A connecting web extending in the longitudinal direction extends between the two web-shaped projections.
- the connecting web is preferably immersed in the receiving pocket or in the free space or the interior of the receiving pocket in the mounted position of the clamping spring on the current bar.
- the two web-shaped projections preferably rest on the receiving pocket outside the receiving pocket in the mounted position of the clamping spring on the current bar, so that the receiving pocket is arranged or clamped between the two web-shaped projections. A displacement of the clamping spring in the longitudinal direction of the holding leg can thus be prevented.
- a recess In order to further improve the positional stability of the clamping spring within the connection arrangement when actuated by means of the actuating lever, a recess.
- the clamping leg of the clamping spring can then be hooked into the recess of the current bar with its clamping edge in an initial position and in particular when assembling the connection arrangement. This also allows torques acting on the clamping spring to be absorbed.
- the recess forms a depression in the clamping section of the current bar.
- the recess can be provided in the form of a notch formed on the clamping section of the current bar.
- the recess preferably extends over the entire width of the clamping section of the current bar.
- the clamping spring can have an actuating arm formed on the clamping leg, which can interact with the actuating lever.
- the actuating arm preferably extends at an angle, in particular at a 90° angle, from the clamping leg in the direction of the holding leg of the clamping spring.
- the actuating arm is preferably designed to be so long that it overlaps the holding leg starting from the clamping leg.
- the actuating lever therefore preferably does not act directly on the clamping leg in order to actuate it, but rather acts indirectly on the clamping leg.
- a contact element can be formed on the current bar.
- the contact element can be, for example, a contact tulip, a contact pin, a contact socket, or the like.
- the contact element is preferably made from the material of the current bar, so that the contact element is preferably formed in one piece with the current bar.
- the contact element can preferably be formed on the holding section of the current bar, in particular on the first leg of the holding section of the current bar.
- connection arrangement can also have a housing.
- the actuating lever can be pivotally mounted on the housing.
- the housing can preferably be made of an insulating material.

- the clamping spring 112 is held or fastened to the current bar 111 via the holding leg 115.
- Fig. 2 the current bar 111 is shown alone.
- the current bar 111 has a clamping section 118 against which the conductor to be connected can be clamped by means of the clamping leg 116 of the clamping spring 112.
- a recess 119 is formed on the clamping section 118, into which the clamping leg 118 can hook with its clamping edge 120 when the clamping leg 118 is in a starting position, as shown in Fig. 1 and 4.
- the recess 119 is formed in the form of a notch on the clamping section 118.
- the recess 119 extends over the entire width of the clamping section 118.
- corrugations 121 or grooves are formed on the clamping section 118, by means of which oxide layers on the connected conductor can be broken up. The corrugations 121 or grooves extend at an angle and thus not parallel to the recess 119.
- the current bar 111 also has a holding section 122 which extends away from the clamping section 118 at an angle.
- a receiving pocket 123 is formed on the clamping section 118, into which the clamping spring 112 can be inserted or pushed with its holding leg 115 in order to be held on the current bar 111.
- the receiving pocket 123 is folded from the material of the current bar 111.
- the receiving pocket 123 has a U-shape.
- the holding section 122 has a first leg 124 and a second leg 125 extending at an angle from the first leg 124.

- the free space 128 forms the interior of the receiving pocket 123 for receiving the holding leg 115 of the clamping spring 112.
- the two side walls 126, 127 are connected to one another via a bend 129.
- the bend 129 is on a longitudinal direction of the second leg 125. extending longitudinal edge 130 of the second leg 125 of the holding portion 122.
- the first side wall 127 of the receiving pocket 123 extends in the plane of the second leg 125 of the holding section 122.
- the second side wall 128 of the receiving pocket 123 extends in a second plane which is spaced apart and parallel to the plane of the second leg 125 of the holding section 122.
- the holding leg 115 is supported with its upper side 135 and its lower side 136 on the two side walls 126, 127 of the receiving pocket 123, whereby twisting or tilting of the holding leg 115 and thus of the clamping spring 112 within the receiving pocket 123 can be reliably prevented.
- Fig. 4 shows the clamping spring 112 on its own.
- the holding leg 115 has a fastening section 131 for fastening the holding leg 115 to the receiving pocket 123.

- the fastening section 131 is formed on a free end of the holding leg 115 of the clamping spring 112, so that the fastening section 131 is arranged at a distance from the arcuate section 117 of the clamping spring 112.
- the U-shape of the fastening section 131 is designed such that it has two web-shaped projections 132, 133 extending transversely to the longitudinal direction of the holding leg 115, which are spaced apart from one another and run parallel to one another.
- a connecting web 134 extending in the longitudinal direction of the holding leg 115 extends between the two web-shaped projections 132, 133.
- the connecting web 134 is immersed in the receiving pocket 123 in the mounted position of the clamping spring 112 on the current bar 111.
