Definitions

  • the invention relates to a box terminal, in particular for installation devices, for example circuit breakers, which leads a clamping screw in a frame-like clamping body and receives a multi-leg pressure piece, one leg of which forms the actual pressure piece between the clamping screw and the clamping body.
  • Box terminals of this type are known in a wide variety of configurations.
  • the known clamp for connecting electrical conductors has a multi-leg pressure piece which is guided in a box clamp like interlocking ring members.
  • a compression spring is arranged so that the clamp is in the closed position in its basic state.
  • the well-known box terminal is said to combine the advantages of spring terminals which immediately clamp a conductor to be inserted and a screw terminal which establishes a long-term secure connection.
  • the invention has for its object to develop a box terminal, as it is particularly advantageous for installation devices such as circuit breakers, and which can be retrofitted on the basis of box terminals by a terminal insert.
  • the described object is achieved in that the pressure piece has a snap holder for the clamping screw and a compression spring for the clamping body on a leg opposite the pressure leg.
  • a box clamp can be formed by retrofitting, and the pressure piece can also be removed if it is is not desired. Since the snap bracket and compression spring are designed on one leg, which is arranged opposite the pressure leg, the pressure piece is held in the open position for insertion of the conductor to be connected, depending on the degree of opening of the clamping screw. With a smaller opening, the effect of a spring clip can also be used. It is also advantageous that the box clamp cannot be shaken into the closed position even in the open position during transport. Finally, the retrofitting of a box clamp with a pressure piece and the easy removal of the pressure piece is advantageous.
  • the pressure piece forms the snap holder by means of free-cut snap arms and the pressure spring by means of free-cut and bent-up pressure arms.
  • the pressure piece can have ribs which stand up with respect to the plane of extent of the snap holder, which forms a lock on the clamping screw head against the connection of conductor rails.
  • the idea essential to the invention can also be found in the pressure piece alone, with which box clamps can be equipped accordingly.
  • the pressure limb can be provided with pressed cross ribs in order to ensure sufficient rigidity on the one hand with sheet-like material, preferably spring bronze, and on the other hand a connection grip.
  • the box clamp 1 guides a clamping screw 3 in a frame-like clamping body 2.
  • the pressure piece On its leg 6 opposite the pressure leg 5, the pressure piece has a snap holder 7 for the clamping screw 3 and a compression spring 8.
  • the compression spring 8 is designed as a two-armed, bent tab made of resilient material, such as it can be seen from Figures 3 and 4 in side view.
  • the entire pressure piece is advantageously made from sheet metal material using the stamping and bending technique.
  • spring bronze is particularly suitable for this purpose, which enables one-piece production with good power conduction and suspension properties.
  • the pressure piece can form the snap holder by means of cut-out snap arms and the pressure spring can be formed by cut-out bent-up pressure arms.
  • An embodiment of the snap bracket 7 can be seen from the supervision of FIG 2. Cutouts 9 provide, in a manner known per se, for functional mobility of the individual parts of a one-piece pressure piece.
  • the pressure pieces according to FIGS. 3 and 4 differ in that the pressure piece according to FIG. 4 has upstanding ribs 10 with respect to the plane of extent of the snap holder, which ribs, when used in a clamping body according to FIG .
  • the ribs 10 are formed in that the pressure arms, which form the compression spring 8, are bent upwards so far that a lock on the clamping screw head prevents the connection of conductor rails.
  • the pressure leg 5 has transverse ribs 11 for stiffening and possibly for increasing the grip for a conductor to be connected. This increases contact security.
  • the insertion protection can only be used due to the raised clamping area, even without raised ribs.
  • the lateral edges of the compression spring 8 in plan view according to FIG. 2 also provide guidance in a housing.

Claims (6)

  1. Borne en forme de boîte, notamment pour des appareils du domaine des installations électriques, par exemple des disjoncteurs de ligne, qui guide, dans un corps de serrage (2) en forme de cadre, une vis de serrage (3) et loge une pièce de pression (4) à plusieurs branches, l'une forme, en tant que branche de pression (5), la pièce de pression proprement dite entre la vis de serrage (3) et le corps de serrage (2), caractérisée par le fait que la pièce de pression (4) possède, au niveau d'une branche (6) située à l'opposé de la branche de pression (5), un système de fixation à encliquetage (7) pour la vis de serrage (3) et un ressort de pression (8) dirigé vers le corps de serrage (2).
  2. Borne en forme de boîte suivant la revendication 1, caractérisée par le fait que la pièce de pression forme le dispositif de fixation à encliquetage (7) grâce à la présence de bras d'encliquetage découpés, et le ressort de pression (8) forme des bras de pression, qui sont découpés et repliés.
  3. Borne en forme de boîte suivant la revendication 2, caractérisée par le fait que la pièce de pression (4) possède des nervures (10), qui font saillie perpendiculairement au plan dans lequel est disposé le dispositif de fixation à encliquetage et qui forment, sur la tête de la vis de serrage, un système de blocage empêchant le raccordement de rails conducteurs.
  4. Borne en forme de boîte suivant la revendication 2, caractérisée par le fait que les bras de pression (ou les ressorts de pression 8) sont repliés vers le haut à leur extrémité de sorte qu'ils forment, au niveau de la tête de la vis de serrage, un système de blocage empêchant le raccordement de rails conducteurs.
  5. Pièce de compression, notamment pour une borne suivant la revendication 1, caractérisée par le fait qu'à l'opposé d'une branche de pression (5), une branche (6) comporte un système de fixation à encliquetage (7) dans un plan par rapport auquel un ressort de pression (8) que comporte la branche fait un angle, notamment 90 degrés.
  6. Pièce de compression suivant la revendication 5, caractérisée par le fait que la pièce de pression comporte des nervures transversales imprimées (11).
