Definitions

  • the invention relates to a terminal for connecting a conductor end to a, in particular fixed, contact, in particular to a busbar or a contact of a fuse carrier, the U-shaped holder comprising the contact itself or having it itself and a clamping member seated in the holder and pressing the conductor end against the contact in the form of a one-armed lever mounted with its lever axis in the holder, the longer arm of which than a push handle underneath Pressing the, shorter, load arm to the end of the conductor and tightening a spring in a hooking with the bracket can be locked
  • the bracket consists of one, especially the rear Molded end of a connector pin, molded part.
  • the molded part has a front wall, a back wall and in between a flat contact surface.
  • In the front wall there is a U-shaped opening through which the conductor end is inserted.
  • the bottom of the opening is higher than the contact surface, so that this is due to the clamping member Conductor end pressed against the contact surface is forced into a double kink becomes.
  • the clamping element in the form of a one-armed lever bent from elastic sheet metal with a load arm bent back under the power arm to form a kind of sleeve pushed with the sleeve onto a rod formed on the molded part as a lever axis.
  • the invention has for its object a simple to manufacture in multiple Way to create executable and easy and quick to use clamp.
  • the holder consists of a U-shaped, resilient sheet metal
  • the lever axis is formed by two stubs emerging in alignment with one another on both sides of the lever and that the two stubs are inserted into recesses of the two, elastically expandable, cheeks of the holder and are stored therein
  • the conductor end between the two U-cheeks is to be inserted parallel to these and for arranging the contact in the terminal the two U-cheeks have an incision with which the holder can be pushed onto a busbar, or have a distance from one another at which the holder can be placed on a contact tongue, or the bracket is in contact with the U-bar itself.
  • the holder consists of a flat, U-shaped sheet, that the lever axis is formed by one end of the lever, which is inserted into a recess of the one cheek of the holder and stored therein or hooked onto a projection or two lateral projections of the U-cheek, the end of the conductor must be inserted between the two U-cheeks transversely to them and the other U-cheek is forked or angled for this purpose, and for arranging the contact in the terminal, the holder with the U-web seat for the conductor end and contact itself.
  • the invention replaces that in the known clamp forming the bracket, complex Shaped part with the molded rod by means of a sheet metal part, which is also otherwise designed two recesses in the first variant and one recess in the second variant and inserting the lever with its lever axis provided on it into the recess (s).
  • Said spring can, for example, hold the pivot bearing of the lever resiliently or be arranged on the power arm in such a way that it presses on the conductor end.
  • the lever itself is the spring in the manner known per se, in the form of a spiral spring, so that no separate part has to be attached for the suspension.
  • the load arm is then preferably bent back, preferably somewhat behind, the lever axis under the power arm. With this shape, the spiral spring is of sufficient length to provide a comparatively large amount of travel. However, their structural dimensions are relatively small.
  • the spiral spring at the end of the load arm is preferably bent out toward the end of the conductor, so that it presses on it with an edge.
  • the edge made of spring steel will then press a little into the conductor end, which usually has a copper sleeve, and hold it accordingly in the longitudinal direction. It can also be created only by a slight notch at the spring end, which can be formed when punching out the spring plate, a centering holding the conductor end in the transverse direction.
  • the lever is expediently bent, as is known per se, in order to hook at the end of the bent section under a projection of the holder.
  • the hook can be formed by a bend, preferably by 180 °.
  • the lever arm has the greatest possible length. The bend also creates a rounding, with which the lever end does not press sharply into the thumb when the spring is tensioned and engaged.
  • the bent portion can be a breakthrough for the engagement of a screwdriver have, such that the bent portion by means of a screwdriver for unhooking something can be bent back.
  • the two stubs emerging from the sides of the lever, which form the lever axis according to the invention, are preferably rectangular. They do not require their own work step; the two stubs can also be shaped when the lever is shaped.
  • the lever in the form of the spring is not weakened by the stubs attached, compared to other possible solutions.
  • the two stubs are expediently mounted in recesses of two elastically expandable cheeks of the holder.
  • the recesses each have approximately the shape of two diagonally cut-out quarter circle cutouts which overlap at the tips.
  • the stubs are then not only guided around the circumference of the recesses. They also have an axle-like bearing in the middle between two tips.
  • the plate of the holder can also in the case of the holder itself representing the contact are made of copper.
  • the spiral spring By influencing the bending stress in the proposed manner, the bending is relocated from places where there is a high bending moment due to the basic shape of the bending spring and the flow of forces, to places with a lower bending moment.
  • the spiral spring can remain dimensioned as a whole without the bend anywhere coming too close to the area of permanent deformation.
  • the spiral spring should be guided laterally in the holder and thus at least in the vicinity of the stub and preferably also at the end of the load arm have the clear width of the holder; at the end of the power arm, it should offer the thumb a comfortable pressure surface.
  • the width of the spiral spring should decrease from the stubs towards the, again wider, ends, ie in the direction of the decrease in the bending moment.

  • the associated lever preferably has a pressure element that branches off along the length of the power arm in order to form the load arm. If it is inserted into the mentioned recess, it can also be hooked on.
