Definitions

  • the invention relates to a connecting terminal according to claim 1.
  • Such connecting terminals with conductor insertion openings arranged on opposite sides of the housing which are also referred to as double terminals or double-sided connecting terminals, are, for example, from FIG DE 10 2013 101 830 A1 or the EP 2 605 335 A2 known.
  • the invention is based on the object of specifying a connecting terminal with a smaller structure.
  • Another advantage is that no additional measures are required to implement a conductor stop in the respective conductor insertion area of the connecting terminal, such as an insulating material wall. This also allows the insulating material housing to be optimized with regard to the necessary material and construction.
  • the conductor stop can in particular prevent the conductor from being inserted too far into the connecting terminal. The user can easily haptically recognize when a conductor has been inserted sufficiently deep into the connecting terminal.
  • the previously mentioned area of the respective clamping spring which is bent in the direction of the busbar can serve as a conductor stop, for example.
  • first and second clamping springs can be arranged closer to one another and can also touch one another, which opens up the possibility of making the busbar shorter than known connecting terminals. In this way, a material saving on the busbar can be achieved.
  • the connecting terminal can be made shorter in the direction in which the busbar extends.
  • the connecting terminal can be implemented particularly flat in this way.
  • busbar can be implemented as a flat component, which minimizes the material and manufacturing costs of the busbar and also has a favorable effect on an overall flat design of the connecting terminal.
  • the through-opening of the busbar can in particular have a non-circular shape in plan view of the busbar, e.g. rectangular, possibly with rounded corner areas. This improves the attachment of the first and / or the second clamping spring to the busbar.
  • the respective, extended end sections of the contact legs of the first and the second clamping spring can thus advantageously be suspended in one and the same through opening of the busbar.
  • the busbar does not have to have a large number of openings, so that a mechanical weakening of the busbar and a deterioration in the electrical conductivity can be minimized.
  • the connecting terminal can be implemented as a single-pole connecting terminal, ie with only one busbar, or as a multi-pole connecting terminal, for example in such a way that several individual connecting terminals are lined up next to one another so that their busbars are arranged essentially parallel to one another.
  • the multi-pole connecting terminal can in particular be designed as a divisible connecting terminal that can be assembled by the user to the desired number of poles.
  • the connecting terminal has a first actuating lever for opening and closing the first spring-force terminal connection by applying the clamping leg of the first clamping spring when the first operating lever is operated and / or a second operating lever for opening and closing the second spring-force terminal connection by applying the Has clamping leg of the second clamping spring upon actuation of the second actuating lever.
  • an extended end section of the contact leg of the first and / or the second clamping spring is suspended in the through opening of the busbar.
  • a particularly compact busbar can be used to fasten the first and / or the second clamping spring.
  • forces of the first and / or the second clamping spring acting on the insulating material housing can at the same time be reduced to an acceptable order of magnitude.
  • the through opening in the busbar is designed as a nozzle (material passage).
  • the nozzle can, for example, have a wall made of the material of the conductor rail and protruding from the surface of the conductor rail surrounding the through opening and surrounding the through opening. This has the advantage that the through opening can be produced in a simple and proven manner. In addition, this creates a mechanical reinforcement of the busbar in the area weakened per se by the passage opening. The electrical properties of the busbar are also improved.
  • the side of the busbar facing away from the clamping point engages behind and / or the area of the contact leg of the second clamping spring that is suspended in the through opening engages behind the through opening of the busbar on the side of the busbar facing away from the second clamping point.
  • the first clamping spring and / or the second clamping spring can be suspended below the busbar, ie on the side facing away from the respective clamping point, and is securely held on the busbar without additional mechanical fixing means.
  • the area of the contact leg of the respective clamping spring which is suspended in the through opening can, for example, engage behind the aforementioned wall of the nozzle.
  • the contact leg of the first clamping spring is supported on the busbar on its side facing the first clamping point and / or the contact leg of the second clamping spring is supported on the busbar on its side facing the second clamping point.
  • the clamping spring on the other side of the busbar, on which it does not engage behind the through opening can be fixed to the busbar and securely supported there. This can be achieved, for example, by the fact that the contact leg of the respective clamping spring has a greater width than the through opening in the area in which the support on the conductor rail takes place.
  • the first and / or the second clamping spring can, for example, have a spring bow via which the contact leg is connected to the clamping leg.
  • the clamping spring can, for example, have an overall V-shape, for example in a kind of loop shape.
  • the first clamping spring and / or the second clamping spring is supported on the insulating material housing.
  • the clamping spring can also be fixed in the insulating material housing, for example in that contact leg area which adjoins a spring arch of the clamping spring via which the contact leg is connected to the clamping leg.
  • the connecting terminal has a plurality of conductor entry openings arranged next to one another on a respective housing side of the insulating material housing, each of which has spring-loaded terminal connections, each with a clamping spring assigned to a conductor entry opening, with extended end sections of clamping springs arranged next to one another being suspended in the same through opening of the busbar.
  • a connection terminal with several conductor entry openings arranged next to one another on one side of the insulating material housing is also referred to as a double connection terminal (with two conductor entry openings arranged next to one another) or multiple connection terminal (with more than adjacent conductor entry openings).
  • the connecting terminal 9 shown is constructed essentially symmetrically with respect to a vertical axis of symmetry. It has a first spring-force terminal connection 1 and a second spring-force terminal connection 2 to the left and right of the vertical axis of symmetry.
  • the first and second spring-loaded terminal connections 1, 2 are arranged in an insulating material housing 4, 5 of the connecting terminal 9.
  • the insulating material housing 4, 5 can, for example, be designed in at least two parts, for example from an upper housing part 4 and a base part 5 that can be connected to the upper housing part 4 by means of latching elements 50.
  • the first spring-loaded terminal connection 1 has a first clamping spring 11 which is angled several times in a loop.
  • the first clamping spring 11 has at one end a clamping leg 12 which is used to clamp an electrical conductor introduced through a first conductor insertion opening 10 against a first clamping point 31 of a busbar 3.
  • a loading area 13 of the first clamping spring 11 on which the clamping leg 12 can be actuated via an actuating lever 19 to open and close the first spring-force terminal connection 1.
  • a spring bow 14 adjoins the clamping leg 12 of the first clamping spring 11, which is then followed by a contact leg 15 of the first clamping spring 11.
  • the contact leg 15 rests against an inner wall area 41 of the insulating material housing 4, 5 and is supported thereon at least in part against the forces absorbed by the clamping leg 12.
  • the first clamping spring 11 extends in the area of the contact leg 15 further into an elongated end section 16 in which the material of the first clamping spring 11 is finally bent in a vertical area 17 in the direction of the busbar 3.
  • the end section 16 of the contact leg 15 extends beyond the vertical area 17 further down through a through opening 30 of the busbar 3 and is finally hooked into the through opening 30 of the busbar 3, e.g. by an end piece 18 of the end section 16 being further angled and thus the busbar 3 engages behind, in particular in an area of the busbar 3 which is designed as a nozzle 33 and which surrounds the through opening 30 in the manner of a base.
  • the second clamping spring 21 can, for example, be shaped in the same way as the first clamping spring 11.
  • the second spring-force clamping connection 2 has a second clamping spring 21 which is angled several times in a loop.
  • the second clamping spring 21 has at one end a clamping leg 22 which is used to clamp an electrical conductor introduced through a second conductor insertion opening 20 against a second clamping point 32 of the busbar 3.
  • a loading area 23 of the second clamping spring 21 on which the clamping leg 22 can be actuated for opening and closing the second spring-force terminal connection 2 via an actuating lever 29.
  • a spring bow 24 connects to the clamping leg 22 of the second clamping spring 21, which is then followed by a contact leg 25 of the second clamping spring 21.
  • the contact leg 25 rests against an inner wall area 42 of the insulating material housing 4, 5 and is supported thereon at least in part against the forces absorbed by the clamping leg 22.
  • the second clamping spring 21 extends in the area of the contact leg 25 further into an extended end section 26 in which the material of the second clamping spring 21 is finally in one Vertical area 27 is bent in the direction of busbar 3.
  • the end section 26 of the contact leg 25 extends beyond the vertical area 27 further down through the through opening 30 of the busbar 3 and is finally hooked into the through opening 30 of the busbar 3, for example by an end piece 28 of the end section 26 being further angled and thus the busbar 3 engages behind, in particular in the area of the busbar 3 designed as a nozzle 33.
  • the Figure 1 shows the first spring-loaded terminal connection 1 with the first actuating lever 19 open, in such a way that the first clamping point 31 is not touched by the clamping leg 12 and an electrical conductor that may have previously been clamped there can be removed. It can be seen that the clamping leg 12 of the first clamping spring 11 is then removed from the first clamping point 31.
  • the second spring-loaded terminal connection 2 is shown in the closed state, ie the second actuating lever 29 is in the closed position. In this state, the end of the clamping leg 22 of the second clamping spring 21 touches the second clamping point 32 of the busbar 3.
  • the busbar 3 has impressions in the area of its first and second clamping points 31, 32, through which the material of the busbar 3 is slightly protruded upwards, i.e. in the direction of the respective clamping legs 12, 22. This improves the clamping of a connected electrical conductor.
  • the busbar 3 is designed in one piece as a flat, short busbar piece. By forming the through opening 30 with the nozzle 33, the busbar 3 is mechanically stabilized in this area and also optimized with regard to electrical conduction.
  • the clamping springs 11, 21 cannot initially, that is to say before they are attached to the busbar 3, in their respective end pieces 18, 28 not yet be bent outward in the manner shown in FIG Figure 1 is recognizable. At first they can run essentially in a straight line. After the clamping springs 11, 21 have been installed in the through opening 30 of the busbar 3, a further production step takes place in which the end pieces 18, 28 are bent outwards, ie in the direction of the respective conductor entry opening 10, 20, and then engage behind the nozzle 33.
  • the first clamping spring 11 is supported in the vertical area 17 on the vertical area 27 of the second clamping spring 21, i.e. the clamping springs 11, 21 support one another in the area of their vertical sections 17, 27.
  • the vertical area 17 also forms a conductor stop when the first conductor is inserted into the insulating material housing.
  • the vertical area 27 also forms a conductor stop when the second conductor is inserted into the insulating material housing.
  • the connecting terminal 9 can be designed as a simple connecting terminal, in which a conductor insertion opening 10, 20 is present on each side. It can also be designed as a double or multiple clamp. In this case, two or more first conductor insertion openings 10 and two or more second conductor insertion openings 20 are arranged next to one another on each side available. A different configuration of the respective actuating lever 19, 29 can be advantageous for such embodiments.
  • the Figure 2 shows in the lower area initially an advantageous embodiment of an actuating lever 6, which can be used as a first or second actuating lever 19, 29, specifically for the case that the connecting terminal has only one conductor insertion opening 10, 20 on each side.

In the closed actuation position, the actuation lever 6 rests with the bearing area 63, in the open position with the bearing area 64 due to the bearing areas 63, 64, which slide on the busbar 3 during the pivoting movement of the actuating lever 19, 29, to be able to absorb deflection occurring during the pivoting movement of the actuating lever 19, 29.
  • the Figure 2 shows in the upper area an embodiment of an actuating lever 6, which is designed for a connecting terminal, in which two spring-loaded terminal connections arranged next to one another are present on each side of the housing. Accordingly, the entire actuating lever 6 is made wider and has two adjacent, recessed areas 65 in which respective clamping springs can be passed. There are three corresponding areas of application 62 provided. In this case, the central area of application 62 acts simultaneously on the two adjacent clamping springs on one side of the connecting terminal 9.
  • the Figure 3 shows the fastening of the clamping springs to the busbar 3 in an enlarged detail.

  • a section of the respective vertical regions 27 of the clamping springs is shown here. These then combine to form a common fastening section 271, which is finally fastened to the nozzle 33 of the busbar 3 via the end pieces 28, which are guided through the through opening 30. It is shown by way of example that the left end piece 28 has already been bent over, as in FIG Figure 1 shown, and the right end piece 28 is not yet bent.
