Definitions

  • the invention relates to a switch, in particular to Circuit breaker or a DC high-speed switch.
  • Conventional switches have a contact lever, which means one formed in this elongated hole on a stationary arranged axis are stored.
  • a contact lever which means one formed in this elongated hole on a stationary arranged axis are stored.
  • the contact lever When switched off and also during a swiveling movement intended to switch on the contact lever has a cylindrical axis trained and functioning as a sliding end section of the elongated hole.
  • the contact lever in Elongate hole from said end section and thereby the Plain bearing is released.
  • swinging the Contact lever becomes a partial adjustment of each other contact surfaces of the main contacts reached.
  • the object of the invention is to provide a switch at an optimal automatic position adjustment of the surfaces of the Main contacts with each other to achieve maximum Contact line is possible.
  • a switch with a Contact lever 1 equipped which is substantially parallel to Drawing plane is pivotable about an axis 2, around the Main contacts 3 of the switch in contact with each other bring.
  • the movement of the contact lever 1 is a Linkage 4 and one not shown in detail Drive device controlled.
  • the axis 2 is - as shown in FIG. 2 in detail - on one Frame 5 is firmly attached and has two tapered Paragraphs 2a and 2b, through which the diameter of the central Section 2c of axis 2 is reduced. This one in the middle Section 2c thus serves as the actual axis of rotation for the Swiveling the contact lever 1.
  • the opening 6 adjusts in this embodiment Elongated hole with two end sections 6a, 6b.
  • the end sections 6a, 6b of the elongated hole 6 are essentially cylindrical formed, the second end portion 6b a smaller Has diameter than the first end portion 6a.
  • the second End section is semicircular and is over a straight opening portion 6c, which of the semicircular ends of the second end section 6b tangentially and has mutually parallel walls, with the first End section 6a connected.
  • the straight opening section (6c) has the length (x) shown in Fig. 3a.
  • the opening edges of the first end portion 6a and the straight one Opening sections 6c are provided with chamfers 6d, the shape of which in essentially the shape of the tapered paragraphs 2a and 2b corresponds to axis 2.
  • the central section 2c is the Axis 2 is 0.1 to 0.9 mm longer than the width of the opposite parallel walls of the straight Opening portion 6c, so that because of this guaranteed axial play of the mounted on the axis 2 Contact lever 1 is possible, the contact lever in the 3b with respect to the axis 2 by one Twist angle up to 5 °.
  • the contact lever 1 In the open state, the contact lever 1 is in the position shown in Fig. 1a. In this position, which is also illustrated by the illustration in FIG. 3a, the axis 2 is in abutment with the cylindrical wall of the second end section 6b and is slidably mounted therein in order to control the tilting or pivoting movement controlled by the linkage 4 of the contact lever 1 to enable.
  • the contact lever 1 is rotated clockwise by the linkage 4 in order to bring the main contacts 3 into contact with one another. After the main contacts 3 are brought into contact with each other, the rotation of the contact lever 1 is continued by a small angle before the device driving the linkage is adjusted.
  • the invention is based on the embodiment shown above not limited.
  • the matching bearing surfaces any other shape combination of axis and joint opening exhibit.
  • the between paragraphs 2a and 2b rotationally symmetrical concave central section of the Axis 2, on which the contact lever 1 is mounted, can also by a circular line can be formed.
  • they have to this section of the second walls End section 6b may also be correspondingly rounded in a circular manner, to ensure the largest possible plain bearing surface.
  • the radius of the rounding of the opening edges in the central portion 6c of the joint receiving opening 6 may be smaller than the radius of the curvature forming end of the second section 6b, to a sufficient game for a rotation of the axis 2 in to ensure the central section.
