Definitions

  • the present invention relates to a device for electrical and mechanical locking for contactors.
  • a locking device associated with two contactors is used in electric motor controls, ensuring reverse gears, or starts star-triangle, in order to prohibit its closing simultaneous.
  • the electrical condemnation between two contactors consists in opening the coil supply circuit of the first contactor by the closing action of the second contactor and vice versa.
  • This system requires that the input-output terminals of the first opening contact are on the upper side of the condemnation device and that those of the second be located on the opposite side. This principle is particularly troublesome with regard to the simplicity of realization of interconnection wiring.
  • the object of the invention is to eliminate these drawbacks, and in particular to improve currently known techniques, by a simplification of the forms of the constituent parts.
  • the subject of the invention is a locking device electrical and mechanical for contactors, intended to be placed between two contactors, comprising a flat box and a cover, of substantially rectangular shape, two input connections and two output connections on them side faces of the housing, two switch devices each comprising a pair of fixed connected contacts respectively to an input connection and a connection of output, and a movable contact actuated by a movable element of conviction ordered by the contactor corresponding to the means of a power take-off, characterized in that the two input connections and one output connection are located on one side of the housing while the other outlet connection is located on the side opposite, and in that one of said devices switches is mounted, between an input connection and an output connection, on a current line extending perpendicular to the side faces of the housing.
  • a case 1 contains all the others elements constituting the device.
  • the case is closed permanently by a cover 1 'by means of the housings 10 located on the box 1 and 10 'pins located on the cover and inserted by force.
  • the hanging function is ensured by fixed hooks 6 ' located on the housing and the cover, as well as “movable” hooks 6, designed in one piece, and mounted on two springs 9, 9 'ensuring the clamping action of hooks 6.
  • the input terminals A ', B' located on the same face side are coupled by a mobile contact system 5 ', 5, at the output terminals: A for A', and B, for B '.
  • the output terminal A is located on the same side face as the input terminals A ', B' and the output terminal B is located on the opposite side.
  • Output contacts A and B are identical manufacturing parts.
  • the movable contacts 5, 5 ', ensuring the cuts, are mounted in slides included in levers 2, 2 '.
  • the contact holding pressure is provided by springs 8, 8 '.
  • Each lever 2, 2 ' carries two power take-off axes 3, 3 'projecting from one side of the device conviction.
  • the two visible axes 3, 3 ' are carried by the lever 2' and protrude from the side of the cover 1 ′, while the two axes 3, 3 'not visible are carried by lever 2 and make projection on the bottom side 1.
  • These axes 3, 3 ′ are manually modular, that is to say that one of them can be manually extracted from its housing to adapt the locking device to contactor travel.
  • levers 2, 2 'of identical manufacture ensuring the opening and closing of the contacts 5, 5 'are mounted in their respective housing axes 3, 3 '. They are held slightly tight by the joint action of a blade in elastic steel 4, 4 '. The recall of levers 2, 2 'is provided by the springs 7, 7 '.
  • the electrical and mechanical locking device provides an arrangement of the connection terminals allowing the use of a feed chute unique for simplified wiring.
  • the closing system of the case is economical and reliable.
  • the modular drive axes allow a interlock mounting on travel switches different.
