Definitions

  • the present invention relates to an arrangement for mechanical coupling an overload relay on a contactor, the overload relay at least a protruding one, for insertion into a mounted on the housing of the contactor Coupling opening determined hook with at least one of two sides of the flat end portion of the hook facing away from each other Has latch part and at least one protruding, for insertion into the contactor's connection terminal and for holding it in place, carries electrically conductive connector pin.
  • EP-A1-0774768 describes an arrangement for mechanical and electrical Coupling an overload relay to a contactor.
  • the overload relay is equipped with elastically deformable hooks Reach for the latch parts of the opening edges in the contactor housing.
  • Rigid, electrically conductive connection pins of the overload relay are in the connecting terminals of the contactor inserted and clamped there. So must the bending moment occurring during operation solely through the connection terminals be included.
  • the elastically deformable hooks relieve the Terminals do not with a bending moment stress.
  • the mechanical and electrical connection between a certain overload relay and a certain contactor In practice, however, there are connection terminals for contactors as required Clamping brackets or with clamps.
  • the object of the present invention is to be universally applicable Arrangement for mechanically coupling an overload relay to a contactor to propose both for contactor connections with clamps as well can be used for contactor connections with clamping claws and thus the economic disadvantages of the known arrangements can be avoided.
  • the hook is stiff and the Coupling opening from one for the insertion running in the connection direction of the entire end region of the hook with the central part provided with the locking part and on both sides of the central opening in the tightening direction of the connection terminals of the contactor, for receiving the flat, trained immediately behind the bolt end portion of the hook Slits together, the latch when connecting the connector pins on a contactor with claws the edge of the connection terminals away slot and when connecting the connection pins to a contactor with drawbars on the edge of the slot facing the connection terminals engages behind.
  • This arrangement can be used universally and allows connection of a single overload relay on contactors both with drawbar connections as well as with clamp claw connections.
  • the rifle casings remain with the exception of the design of the electrical connections unchanged.
  • the electrical connections of the contactor can be made independent of the end to be connected Overload relays can be freely selected.
  • the hook inserted operationally into the coupling opening has an advantage on its side facing away from the bolt part, immediately behind that in the slot lying, flat end area the further insertion of the hook into the Preventing the coupling opening, which is in contact with the lower part of the contactor housing Stop on.
  • the stop ensures the exact position of the overload relay in relation to the contactor.
  • An overload relay 1 is shown in perspective in FIG.
  • the overload relay 1 is provided for mechanical coupling to a contactor 2 (Fig.2).
  • the overload relay 1 has a protruding hook 3.
  • On the flat End area 4 of this hook 3 is formed on a laterally projecting locking part 5.
  • Contactor 2 has a central opening 7 and on both sides of this central opening 7 in Direction of the contacts of the contactor 2 and in the opposite direction aligned slots 8, 9 having coupling opening available.
  • the central opening 7 is for the introduction of the entire end portion 4 of the hook 3 with Bolt part 5 is provided.
  • the slots 8, 9 are only so wide that only the flat one End area 4 of the hook 3, which lies immediately behind the locking part 5, fits in.
  • the overload relay 1 is with electrically conductive, for the electrical and mechanical connection of overload relay 1 to contactor 2 provided connection pins 10 provided.
  • the contactor 2 is equipped with clamps 12 electrical connection terminals 11 provided.
  • the active parts of a terminal 11 with clamps 12 are shown outside the contactor 2 to the details of To recognize terminal 11 better.
  • the mechanical coupling of the overload relay 1 to the contactor 2 is carried out by the end region 4 of the hook 3 into the central opening 7 of the coupling opening and the connector pins 10 are inserted under the clamps 12. Then the screws 13 of the terminals 11 are tightened. At the Tightening the screws 13, the connection pins 10 with the clamping claws 12 and thus also the entire overload relay 1 downwards, in the tightening direction the terminals 11 pressed. With this relative shift between the overload relay 1 and the contactor 2, the flat end portion 4 of the Hook 3 in the slot 9 facing away from the connecting terminals 11 of the coupling opening pushed in. The latch part 5 engages behind the hook 3 Edge of the slot 9.
  • the overload relay 1 shown in FIGS. 4, 5 and 6 is the same as that shown in FIGS Figures 1, 2 and 3 are identical and bear the same reference numerals.
  • the contactor 15 visible in FIGS. 4, 5 and 6 differs from contactor 2 of Figures 1, 2 and 3 only in the connecting terminals 16. Die Lower parts 6 of the contactors 2 and 15 are identical and therefore also carry the same reference numbers.
  • connection terminal 16 of the contactor 15 is next to the contactor 15 in FIG shown alone.
  • This connection terminal 16 has a pull bracket 17.
  • the coupling can be done by loosening the screws 19 of the connection terminals 16 be solved again.
