Definitions

  • connection terminal for electrical installation apparatus comprising an approximately annular clamping box which is engaged with a clamping bracket by means of a bolt and which, within a zone predetermined by the clamping bracket, is guided so as to be able to slide in height in a compartment of the housing of the apparatus of the installation, by cooperation with the bolt and a retaining device acting so as to produce a connection controlled by a strength.
  • connection terminal is for example described in DE-U-83 17 416 and it is advantageously used in line protection circuit breakers for the connection of both busbars and single-wire conductors.
  • Automatic locking of the clamping box in any position adjusted is obtained here by means of a leaf spring inserted in the housing.
  • This retaining device has the disadvantage of an additional part for which are required, in addition to manufacturing costs, assembly costs.
  • the object of the invention is to develop, for the abovementioned connection terminal, a retaining device which is even simpler in structure and which is shaped favorably for installation, while guaranteeing inexpensive manufacture.
  • connection terminal having the characteristic features of claim 1.
  • Advantageous improvements and embodiments of the invention are also the subject of the secondary claims.
  • the invention is advantageous insofar as the retaining device for the height-adjustable clamping box can be directly shaped during the production of the parts of the housing. This eliminates an additional part and saves assembly costs.
  • the protrusions of the retainer are arranged so that the upper position of the clamping box is normally kept as the basic position during the manufacture of the device and that the terminal bolt is also assigned a corresponding higher assignment. This identical position for all devices does not change either during transport or during handling at the mounting location.
  • connection terminal forms a practical installation aid.
  • the connection terminal includes a metal clamp 1 approximately in the shape of a U or a frame, in a side view, which is fixedly anchored in a housing 2, made of an insulating material, of an apparatus for installation not shown in detail.
  • a passage hole 1a ⁇ through which a bolt 3 penetrates into a tapped hole 4a of an approximately annular metallic clamping box 4.
  • This surrounds a lower wing 1b of the clamping bracket and it is guided so as to be able to slide in height in a compartment 2a of the housing composed of two shells 2b, 2c.
  • the clamping box 4 can be made to slide inside a sliding zone "s" from an extreme upper position (FIGS. 1 or respectively 3) to an extreme lower position (FIGS. 2 or respectively 4), depending the bolting depth of the bolt 3.
  • the embodiment of the clamping bracket 1 guarantees, in cooperation with the compartment, the guidance of the clamping box and sufficient protection against torsion.
  • a retaining device is arranged in the compartment in the form of two elastic projections 2d, 2e which are arranged in lateral projection and which, in the extreme upper position, take slightly below the lower side 4b of the clamping box, fixing the latter in its position .
  • the projections 2d, 2e, arranged one opposite the other, are preferably made in the form of lips and they are, with sufficient flexibility, shaped, in particular by molding, directly during manufacture, on the shells 2b, 2c of the housing made of thermoplastic material.
  • an elastic tongue 2g which is shaped on the housing in the region of the upper wing 1a of the clamping bracket 1, is arranged as a retaining device in the compartment 2a.
  • the elastic tongue previously bent in the compartment, represents, in an isolated form, part of the wall of the compartment and exerts, from one side, an elastic pressure on the clamping box 4 which is therefore pressed on the opposite wall of the compartment and is held by a force-controlled link.
  • This latter wall can additionally also be provided with a lip-shaped projection 2d ⁇ to thereby determine the upper position of the clamping box (FIG. 3).
  • a busbar not shown which can be introduced between a head 3a of the terminal bolt and the upper wing 1a of the clamping bracket.
  • the bolt head which is partially covered by a plate in console 2f, is accessible via an opening 2f ⁇ arranged concentrically, so that the bolt can be actuated by a screwdriver. In the case of a current right-hand thread, a rotation to the right causes the busbar to be tightened.
  • Rotating the terminal bolt to the left has the effect that the bolt head, by its marginal zone, comes to bear on the plate in console 2f. This then forms a fixed counter-stop so that the terminal bolt brings, in accordance with the rotation to the left, the clamping box to slide between the elastic projections, in the direction of the lower extreme position.
  • the latter is provided with approximately parallel side surfaces 4c, in the sliding zone of the projections or respectively of the elastic tongue.
  • the sliding of the clamping box in the lower position can also be obtained by manual pressure on the bolt head.
  • the clamping box is again pulled upwards between the projections, until, depending on the cross-sections of the conductors, the terminal bolt and the box tighten each other.
  • the clamping yoke serves here as a stop intended to oppose the pressing force produced by the terminal bolt.
  • the length of the terminal bolt is adjusted on the clamping bracket.
  • the cooperation of all the parts of the connection terminal gives an advantageous installation aid, the console plate 2f preventing the fall of the terminal bolt and also guaranteeing safety against any involuntary contact with conductive parts current.
  • a comparable retaining device for the clamping box can be introduced, as an additional part, directly during manufacture or even later during mounting.
