Definitions

  • the present invention relates to a connecting element for the electrically conductive connection of a plug pin to a conductor wire according to the preamble of claim 1.
  • Such a connecting element is known for example from EP-A-00 73 275.
  • the body consists of a bracket, which has an abutment leg and a semicircular groove and a center piece, the groove being formed by a stump of the bracket.
  • the mounting of the clamping plate as a swivel part on the groove requires a comparatively wide design of the connecting element, which limits its use for small switches and reduces the distance between adjacent connecting elements.
  • Another disadvantage with regard to the size is that the clamping element is only an angled bracket in principle, which deforms when the clamping screws are tightened and therefore reduces the clamping force.
  • the object of the present invention is therefore to improve a connecting element of the type mentioned at the outset in such a way that, with smaller outer dimensions, at least the same clamping forces can be generated without thereby reducing the ease of use.
  • the clamping surface of the clamping plate facing the first-mentioned inner surface is preferably provided with two concave recesses for partially enclosing the wire-shaped conductors.
  • a wedge surface parallel to the second inner surface is arranged at the upper end of the displacement path of the clamping plate. This makes it possible to simultaneously force the clamping plate away from the first-mentioned surface when relaxing.
  • reference number 1 denotes the rear end of the housing of a switching and signaling device which is provided with plug pins 2 for the connection of electrical conductors, only one of the plug pins being shown in the drawing.
  • the plug pin 2 ends in a cavity 3 on the back of the switch housing, which is closed off at the rear by a cover 1a.
  • a socket firmly connected to an electrical conductor can be plugged onto the plug pin 2, an opening that is axial to the plug 2 being provided in the cover 1a for the passage of the conductor.
  • a clamp connection is provided for connecting a conductor 4 which does not have a socket to the plug pin 2.
  • the plug pin 2 is surrounded by a frame-shaped body 5, which at one end closed by a bottom 6 and open at the other end.
  • a wall of the body 5 forms an inner surface 7 which bears against the plug pin 2 and which is opposite a second inner surface 8 which intersects it at an acute angle.
  • the two inner surfaces 7 and 8 intersect at an angle of approximately 30 ° and converge towards the bottom 6 in which a threaded bore 9 with the bore axis 10 is arranged.
  • the bore axis 10 forms with the inner wall 7 by an angle of approximately 15 o, and preferably on the bisecting line between the two surface 7 and 8.
  • a screw 11 is screwed whose shank has adjoining the screw head a cylindrical neck 12 , on which a clamping plate 13 with a slot opening 14 penetrated by the screw 11 is held captive.
  • the clamping plate 13 has the two inner surfaces 7 and 9 facing clamping surfaces 15 and 16, the clamping surface 16 having two concave recesses for partially enclosing an electrical conductor 4. If the clamping plate 13 is in the outer position shown in Fig. 1, the screw 11 is rotated clockwise in Fig. 2, it moves the clamping plate 13 against the bottom 6, the clamping surface 15 sliding along the inner surface 8 and thereby against the Inner surface 7 is pushed.
  • the clamping plate 13 is lifted off the electrical conductors 4 when the screw 11 is unscrewed (in FIG. 2: turning counterclockwise), a lug 19 is attached to the cover 1a, which on free end is provided with a wedge surface 20 parallel to the inner surface 8.
  • the cover 1a connected to the switch housing 1 has two openings 21 and 22. Through the opening 21, the screw 11 is accessible from the outside, whereas the electrical conductor can turn through the opening 22 inserted into the body 5.
  • the cover 1 a is replaced and the body 5 is removed from the plug pin 2 and removed.
  • the command or signaling device is to be provided with a terminal connection option, a cover 1a with the openings 21 and 22 is selected and a body 5 is pushed over the plug pin 2.
  • the nose 19 can be connected to the body 5 with the wedge surface 20 instead of with the cover 1a.
  • clamping plate can be secured by positive locking with parts of the body 5 against turning with the screw 11.

Claims (3)

  1. Connecteur (1) destiné à relier électriquement une broche (2) à fiche à un fil conducteur (4), comprenant :
    - un corps (5) présentant un fond (6) et de part et d'autre de celui-ci, deux parois internes (7, 8) face à face,
    - une vis de serrage (11) est vissée dans un alésage fileté (9) du fond (6),
    - une plaque de serrage (13) montée sur la vis (11) et en appui contre la seconde paroi interne (8) tandis que la première paroi (7) sert de surface d'application de la broche (2) à fiche,
    - la vis de serrage (11) traverse une ouverture (14) en forme de fente dans la plaque de serrage (13),
    - dans le fond (6), le long de la paroi interne (7) un passage (2a) permet l'enfoncement de la broche (2),
    caractérisé en ce que le corps (5) est constitué d'un cadre rigidifié d'un côté par le fond (6), dont la seconde paroi interne (8) est plane et orientée, par rapport à la première, selon un angle aigu dirigé vers le fond (6), tandis que la plaque de serrage (13) peut se déplacer autour de la vis de serrage (11) d'une des parois (7, 8) vers l'autre, l'axe (10) de la vis (11) occupant une position proche de la bissectrice de l'angle aigu formé par les parois (7, 8).
  2. Connecteur selon la revendication 1, caractérisé en ce que la tige de la vis de serrage (11), présente, au raccordement avec la tête de vis, une partie cylindrique (12) logée dans la fente de l'ouverture (14) de sorte que la rotation de la vis (11) entraîne le déplacement de la plaque de serrage (13) entre les parois (7, 8)), selon la direction de vissage, tandis qu'au niveau de l'extrémité, opposée au fond (6), de la course de la plaque de serrage (13), il est prévu une pièce en coin présentant une surface (20) parallèle à la seconde paroi interne (8) de manière à amener la plaque de serrage (13) en appui sur cette paroi.
  3. Connecteur selon la revendication 1, caractérisé en ce que la face (16) de la plaque de serrage (13) située en regard de la première paroi interne (7) présente deux évidements concaves (17) servant à entourer partiellement des fils conducteurs (4).
