  • DE 36 37 316 A1 shows a connecting terminal with a connecting plate and a clamping spring, the clamping spring and the connecting plate forming a clamping point for an electrical conductor to be clamped.
  • a release member is guided through an opening of the connection plate and lies on a sliding surface of the clamping spring, the release member being set up to open or close the clamping point.
  • DE 10 2015 115 791 B4 discloses a conductor connection contact element with a busbar and a clamping spring, the clamping spring being arranged within the busbar piece.
  • the busbar piece has two side walls, an actuating section of the clamping spring projecting through a recess on one of the side walls and the actuating section being set up for opening and closing a clamping point for an electrical conductor to be clamped by means of an actuating tool.
  • the conductor connection terminal have an actuating element which is arranged pivotably over the busbar section and is in operative connection with the actuating section of the clamping spring with an actuating finger extending next to the partition wall and is designed to open or close the clamping point.
  • actuating element which is arranged pivotably over the busbar section and is in operative connection with the actuating section of the clamping spring with an actuating finger extending next to the partition wall and is designed to open or close the clamping point.
  • the busbar section and the partition are formed in one piece from the contact frame and thus from the same material.
  • the busbar section can be formed from a different material than the partition.
  • the partition can consist of a plastic, while the busbar section is made of an electrically conductive metal.
  • busbar section acts as an electrically conductive connection and as a partition for the actuating section of the clamping spring, in that it is passed through the wall opening of the partition.
  • the clamping point and the actuating section of the clamping spring are thus spatially separated by the busbar section.
  • the partition can be arranged between the busbar section and the wall opening and the actuating finger can protrude into the wall opening.
  • the actuating element can be mounted with a bearing opening and a pin which plunges into the position opening. It is also advantageous if the bearing opening is an elongated hole and the pin is slidably mounted in the elongated hole. In this way, reliable guidance of the actuating element can be provided, which enables the clamping point to be opened or closed.
  • the actuating element can be self-locking in its position in an open and / or a closed position of the clamping point. It is also advantageous if the actuating finger is directed from a pivot bearing area of the actuating element to rest on the actuating section of the clamping spring out of the direction of force of the clamping spring pointing towards the pivot bearing area and towards the spring arch, the actuating finger in the open position between one of the clamping limbs and the pivot bearing area Perpendicular of the clamping leg and the spring arch rests on the actuating section. In this way, an actuating element can be provided which remains self-locking in the open position without being dependent on additional aids or constructive measures.
  • the pivot bearing area is the area in which the actuating element can be pivoted into an open position or a closed position.
  • the contact leg of the clamping spring can have at least one curvature.
  • the spring root is relieved by a curvature of the contact leg and thus increases the elastic deformability.
  • a low overall height can be achieved by increasing the maximum deflection of the spring. The occurrence of fatigue can thus be reduced and the frequency of actuations increased.
  • the curvature of the contact limb prevents the spring from falling out of the conductor rail section. in contrast to known conductor connection terminals, no additional fixing elements have to be used. This has the advantage that a bulk connector suitable for bulk goods can be provided.
  • the curvature of the contact leg of the clamping spring is not limited to one of the above-described and subsequent embodiments, but rather can also be used in other conductor connection terminals in order to achieve a low overall height and / or to fix the clamping spring without additional elements.
  • the contact leg can be supported on a contact surface of the contact frame diametrically opposite the busbar section. It is also advantageous if the contact leg is held in a form-fitting manner on the bearing surface. This has the advantage that a bulk connector suitable for bulk goods can be provided. It is advantageous if the contact leg is curved. It is conceivable that the contact leg is supported at certain points by the curvature at two points on the contact surface of the contact frame.
  • a plug contact connection for plug contacting of a plug element can be arranged on the contact frame. It is also advantageous if the plug contact connection is a fork contact formed in one piece with the contact frame. In this way, a conductor terminal can be provided, which enables an electrically conductive connection with a plug contact element inserted into the conductor terminal.
  • the conductor connection terminal can have an insulating material housing with a conductor insertion opening for inserting the electrical conductor, the contact frame and the actuating element being arranged in the insulating material housing. It is furthermore advantageous if a plurality of contact frames, each with associated actuating elements and a clamping spring, are accommodated in the insulating material housing, wherein in each case there is a conductor insertion opening opening out to a clamping point in the insulating material housing. Conductor terminals with different numbers of poles are conceivable depending on the application.
  • the indefinite term "a” is to be understood as such and not as a numerical value.
  • the insulating material housing can therefore also have further conductor insertion openings, plug contact openings, busbar sections and associated clamping springs, for example for a multipole conductor connection terminal.
  • FIG. 1 shows a conductor terminal 1 in a side sectional view.
  • the conductor connection terminal 1 has a contact frame 2 and a clamping spring 3 for connecting an electrical conductor, the clamping spring 3 being arranged on the contact frame 2.
  • the contact frame 2 has a busbar section 4 and a partition 5, the partition 5 having a wall opening 6.
  • the clamping spring 3 has a clamping leg 7 with a clamping edge 8 aligned with the busbar section 4, the clamping edge 8 and the busbar section 4 forming a clamping point for an electrical conductor to be clamped.
  • the clamping spring 3 also has a spring arch 9 which merges into a contact leg 10.
  • the busbar section 4 and the partition 5 are integrally formed from the same material. However, it is also conceivable that the partition 5 and the busbar section 4 can be formed from different materials.
  • the contact leg 10 bears against the contact frame 2 on the side opposite the busbar section 4 and is curved in this area.
  • the contact leg 10 is therefore not flat on the contact frame 2, but rather only touches it in two points.
  • the bending joint can be relieved, so that the number of load changes of the clamping spring 3 can be increased and, on the other hand, no additional elements are required to hold the clamping spring 3 in the contact frame 2.
  • the clamping spring 3 is thus positively connected to the contact frame 2 and thus provides a contact insert suitable for bulk goods.

  • the actuating element 14 has an actuating finger 18, the actuating finger 18 extending next to the partition 5 on the side facing away from the clamping point to the actuating section 17 of the clamping spring 3 and being operatively connected to the actuating section 17 such that the actuating element 14 is designed to open or close the terminal point.
  • the actuating section 17 is arranged at one end of the clamping leg 7 so that a low actuating force leads to the deflection of the clamping leg 7 of the clamping spring and thus to the opening of the clamping point. This enables easy handling of the conductor terminal 1.

  • Figures 3 and 4 show a contact frame 2 for a conductor terminal in a perspective view. It is clear that the contact frame is made in one piece.
  • the contact frame 2 is U-shaped, the busbar section 4 merging into the partition 5 and then merging into a contact surface 19 opposite the busbar section 4.
  • the partition consists of a material different from the busbar section 4, such as a plastic, in order to electrically isolate the clamping point and the actuating section 17 of the clamping spring from one another.
