Definitions

  • the present invention relates to a protective conductor terminal, which can be snap-fitted onto or removed from a mounting rail, preferably designed as a protective conductor busbar, with a terminal body made of non-conductive material and terminals integrated therein, which are connected to an electrically conductive plate, which in turn is connected is connectable to the mounting rail, the plate in conductive connection with the terminals being pulled down to the base of the terminal body and angled at the lower end in some areas to form contact surfaces which are intended to bear against the mounting rail and that spring means are provided in the terminal body are to press the terminal with the contact surfaces of the conductive plate against the mounting rail.
  • Tightening or loosening these contact screws does not, of course, correspond to the purpose of snap fastening and thus complicates the quick and uncomplicated mounting of the protective conductor terminals on the mounting rail.
  • the object of the present invention is to design a protective conductor terminal so that it also ensures a reliable electrical connection between the protective conductor terminal and the mounting rail by simply snapping onto a mounting rail.
  • the clamp according to the invention is characterized in that the spring means consist of a single, substantially U-shaped clamp-like bracket which, with its connecting web, passes above the angled end regions of the conductive plate and bears against it, while the resilient projecting downwards Legs are slightly bent inwards, to engage under the contact surfaces of the mounting rail from the side when the clamp is placed on the mounting rail, on the back of the angled end regions of the conductive plate, preferably elevations formed from the plate material are provided, against which the connecting web of the bracket abuts and can thus extend freely between the ridges formed and thus supports the clamping action of the spring.
  • the end of at least one of the resilient stirrup legs can have an outwardly projecting extension, which makes it easier to release the snap closure.
  • This leg extension can have an opening for attaching an actuating lever (tool, eg screwdriver).
  • the invention thus relates to a spring-loaded protective conductor terminal with screwless snap-on device for attaching it to a mounting rail.
  • the protective conductor terminal 1 shown in the drawing is intended to be snapped onto a mounting rail 2 (protective conductor busbar).
  • a bow-shaped spring 3 is provided on the foot part of the terminal body 4 consisting of non-conductive material, which engages under the side flanges 5, 6 of the mounting rail 2 and thus presses the protective conductor terminal 1 against the mounting rail 2.
  • the spring 3 leads behind the right-angled foot part 7 of an electrically conductive plate 8 which is guided downward and on which, in the example shown, two clamps 9, 10 integrated therein (screwless clamps in the exemplary embodiment shown, which are depressed in the middle of the clamp body 4) can be brought into a position by means of a tool which can be inserted through the openings 11, 12 and which allows the insertion of conductors to be clamped through the lateral openings 13, 14, the conductors being automatically clamped in the terminals after the tool has been withdrawn; if the connection is to be released, the clamps are again pressed down using the tool) (conductive contact).
  • One spring leg 3 has an outwardly projecting extension 17, which allows the snap connection to be released in the simplest way and the protective conductor terminal 1 to be removed from the mounting rail 2.
  • the spring extension 17 is provided with an opening 18 which allows the insertion of a lever (e.g. screwdriver) in order to easily release the spring (by lifting).
  • a lever e.g. screwdriver

Claims (3)

  1. Borne à fil de terre qui peut être placée par enclenchement sur un rail porteur (2) réalisé de préférence sous forme de rail collecteur de bornes à fil et qui peut être enlevée de celui-ci, avec un corps de borne (1) en un matériau non conducteur et des bornes (9, 10) intégrées dans celui-ci qui sont en liaison avec une plaque (8) électriquement conductrice pouvant être reliée elle-même au rail porteur (2), la plaque (8) en liaison conductrice avec les bornes (9, 10) étant tirée vers le bas vers la base du corps de borne (1) et est coudée à l'extrémité inférieure par zones (7) pour constituer des surfaces de contact destinées à s'appliquer au rail porteur (2), et en ce que sont prévus au corps de borne (1) des moyens formant ressort (3) pour appliquer la borne avec les surfaces de contact (7) de la plaque conductrice (8) contre le rail porteur (2), caractérisée en ce que les moyens formant ressort sont constitués par un seul étrier (3) en forme de pince sensiblement en U qui traverse avec sa baguette de liaison (3') au-dessus des zones d'extrémité coudées (7) la plaque conductrice (8) et s'applique à celle-ci tandis que les branches (3) faisant élastiquement saillie vers le bas sont légèrement courbées vers l'intérieur pour, lorsque la borne est placée sur le rail porteur (2), passer sous les surfaces de contact du rail porteur (2) depuis le côté, et sur le côté arrière des zones d'extrémité coudées (7) de la plaque conductrice (8) étant prévues des surélévations (15, 16) réalisées de préférence dans le matériau de la plaque contre lesquelles s'applique la baguette de liaison (3') de l'étrier (3) qui peut donc s'étendre librement entre les surélévations formées (15, 16) et qui renforce ainsi l'action de serrage du ressort.
  2. Borne selon la revendication 1, caractérisée en ce que l'extrémité d'au moins l'une des branches d'étrier élastiques (3) présente un prolongement (17) faisant saillie vers l'extérieur qui facilite le relâchement de la fermeture par enclenchement.
  3. Borne selon la revendication 2, caractérisée en ce qu'il est prévu dans le prolongement de branche (17) faisant saillie vers l'extérieur une ouverture (18) pour l'application d'un levier d'actionnement.
