Definitions
- the invention relates to an electrical circuit breaker with a movable contact arrangement and with a drive device which actuates the contact arrangement for switching on and off and which is articulatedly connected to the contact arrangement by a drive lever, a transverse bore for receiving a the drive lever in an insulating contact lever carrier of the contact arrangement is arranged with the contact arrangement connecting bearing pin and the bearing pin is secured against removal from the transverse bore by a locking screw.
- a circuit breaker with the features mentioned has become known essentially from DE 44 16 105 Cl.
- the locking screw is in a conductive connection with the bearing pin. This not only includes the bearing pin in contact with the drive lever, but also the one
- the object of the invention is to increase the dielectric strength of the movable contact arrangement and thereby to improve the security against electrical errors for given dimensions.
- the above object is achieved in that an axially blocking the bearing bolt, consisting of insulating plastic on the contact lever carrier Locking piece is attached by means of the locking screw.
- a further dielectric improvement can be achieved in that the locking screw engages in a receiving opening arranged at right angles to the transverse bore and ends at a distance from the bearing pin. In contrast to the previous design of the contact lever carrier, the screw therefore no longer acts as an electrode at earth potential.
- the locking piece for the bearing pin can be designed as a protective element for covering an assembly opening of the contact lever carrier which provides access to the head piece of the bearing pin. This measure also works in the sense of increasing the creepage distances.
- the locking piece can have a rib for mutual support of a locking web located in front of the head piece of the bearing pin and a locking leg filling the assembly opening.
- the rib acts as a stiffener and therefore allows the locking piece to be manufactured as a light plastic molded part.
- Figure 1 shows a schematic representation
- FIG. 2 shows a contact lever support shown in FIG. 1 on a larger scale and partly in section.
- FIG. 3 is an illustration of section III-III in FIG. 2.
- the low-voltage circuit breaker 1 shown schematically in FIG. 1 has a movable contact arrangement 2, which includes a connecting bar 3, flexible current strips 4 and at least one movable contact lever 5.
- a contact lever carrier 6 can be pivoted by a drive device 7, a shift shaft 10 actuated thereby and drive lever 11 for switching on and off.
- the movable contact lever 5 cooperates with a stationary counter contact 12 which is connected to a further connecting rail 13.
- FIGS. 2 and 3 Details of the connection of the drive lever 11 to the contact lever carrier 6 are described in more detail below with reference to FIGS. 2 and 3.
- a mounting opening 14 is shown on the top of the contact lever carrier 6, in which a locking piece 15 is located.
- a bearing pin 17 In a transverse bore 16 of the contact lever carrier 6 there is a bearing pin 17 which passes through a bearing opening of the drive lever 11. It is indicated in FIG. 3 that two parallel drive levers 11 are provided for the power transmission to the contact lever carrier 6.
- a barrier 20 of the Locking piece 15 is located in front of a head piece 21 of the
- Bearing pin 17 and secures it against axial displacement in the transverse bore 16.
- a locking screw 22 engages in a receiving opening 23 of the contact lever carrier 6 and passes through a through opening of a locking leg 24 of the locking piece 15. As can be seen in particular from FIG. 3, the locking leg 24 of the locking piece 15 fills the mounting opening 14 of the contact lever carrier 6.
- a rib 26 extends between the locking leg 24 and the locking web 20.
- the rib 26 lies over part of its length against a wall surface 25 of the contact lever carrier 6 delimiting the mounting opening 14. Axial forces which may arise from the bearing bolt 17 are thus introduced directly into the contact lever carrier 6, bypassing the locking screw 22.
- connection between the contact lever carrier 6 and the drive lever 11 can be established in a simple manner by inserting the bearing bolt 17 into the transverse bore 16.
- the assembly opening 14 is provided with a lateral mouth 27.
- the locking piece 15 is then inserted into the mounting opening 14 from above, which is only possible if the locking bar 20 can join the head piece 21 of the bearing pin 17.
- the locking screw 22 is also inserted into the mounting opening 14 from above.
- the locking screw 22 is of such a length that a reaching fastening is achieved, but there is still a distance from the bearing pin 17. So that the locking screw
- Grounding drive device 7 is.
- Locking screw 22 can therefore not act as an electrode.
