Definitions
- the present invention relates to a contact arrangement for electromagnetic Switchgear, especially for contactors, with a housing, with in Housing arranged stationary and can be brought into and out of engagement with them, movable contact pieces, with one through the armature of the electromagnetic Drive longitudinally movable contact bridge carrier, in its window-like opening the movable contact piece with one on one housing-connected abutment supporting contact pressure spring can be moved longitudinally is arranged guided.
- From DE-A1-3440229 is a contact arrangement of the type mentioned known. This arrangement is used for the movable contact piece to achieve a constant lifting force characteristic.
- the contact pressure spring of the movable contact piece not as previously known on Contact carrier, but supported on a housing-connected abutment.
- the electromagnetic switching device To be able to mount the abutment is for the electromagnetic switching device a two-part housing is provided. By closing the housing halves the abutment is caught, the correct position of the abutment only accessible through special, expensive guide surfaces in the housing is. The abutment is uncontrolled when the housing halves are closed between these.
- the object of the present invention is to provide a contact arrangement for electromagnetic Develop switchgear, especially for contactors, at which the contact pressure spring of the movable contact piece is supported on the housing is economical in terms of production and also automated assembly is advantageous.
- the task is solved in that the housing is transverse to the direction the contact movement is formed in one piece and that the one for the contact pressure spring provided abutment provided centering through the window-like
- the opening of the contact bridge carrier is inserted under the contact pressure spring and is held in the housing by positive connections.
- the one-piece design of the housing is simple to manufacture and spares an assembly of housing halves.
- the abutment is proportionate to the simple and also automatable assembly under the contact pressure spring inserted and in the housing by positive connections held.
- the abutment can rest on the housing with both ends.
- the two-sided Support of the abutment is sufficient, especially for switchgear with a large housing advantageous.
- the abutment can also be designed like a console and only with its one End area in the housing be secured against bending.
- the console-like training the abutment can be especially in the case of relatively smaller housings Switchgear bring advantages.
- the electromagnetic switching device shown in section in Figure 1, or Schütz has one composed of an upper part 1 and a lower part 2 Housing on.
- the upper part 1 of the housing contains the fastened therein stationary contact pieces 3, 4.
- the arranged on a contact bridge 5 movable contact pieces 6, 7 are with the fixed contact pieces 3, 4 in and disengageable.
- the contact bridge 5 is in a window-like Opening 8 of the contact bridge support 9 and can be in the switching direction be moved.
- the contact bridge support 9 is connected to the armature 10 of the Electromagnets of the electromagnetic drive coupled, as in the EP-A2-0739021.
- the contact bridge 5 is at a by excitation of the electromagnetic Drive causes the switching device to switch off via a towing connection brought with the contact bridge support 9 in the off position.
- the contact bridge 5 In the event of an interruption in the excitation of the electromagnetic drive caused switch-on movement of the switching device, the contact bridge 5 from by a spring moving contact bridge carrier 9 in the switch-on direction Cut. The contact bridge 5 is then in 11 by the contact pressure spring brought the switch on.
- the contact pressure spring 11 is on a housing-connected abutment 12 a centering point 13 formed thereon.
- This abutment 12 is in FIG. 2 from above and in FIG. 3 from below, on a different scale shown.
- the abutment 12 is bar-shaped and lies with its two End areas on the upper part 1 of the housing. Because the top part 1 of the housing transversely to the direction of the contact movement, the abutment 12 at the assembly of the contactor from the side through the window-like opening 8 of the Contact bridge support 9 pushed under the contact pressure spring 11. In the Operating position is the abutment 12 by positive connections in the held in the correct position.
- FIG. 4 shows another electromagnetic switching device in section. Also at this switching device is the housing of an upper part 14 and a lower part 15 composed. Both the upper part and the lower part 15 are formed in one piece transversely to the direction of the contact movement.
- the fixed contact pieces 16, 17 are attached to the housing.
- the one Contact bridge 18 arranged movable contact pieces 19, 20 are with the stationary contact pieces 16, 17 can be disengaged by the contact bridge carrier 21 moved by the armature 22 of the electromagnetic drive becomes.
- the contact bridge 18 lies in a window-like opening 23 of the contact bridge support 21 and can be in the direction of movement of the armature 22 be moved.
- the contact bridge 18 is over when the switching device is switched off a towing connection with the contact bridge carrier 21 against the force of Contact pressure spring 24 brought into the off position.
- the separation of the movable contact pieces 19, 20 of the fixed contact pieces 16, 17 takes place.
- the contact pressure spring 24 is on a housing-connected abutment 25 a centering point 26 formed thereon is supported.
- This abutment 25 is shown in perspective in a different scale in FIG.
- the abutment 25 is formed like a console and only with its one end region in the upper part 14 attached to the housing.
- the upper part 14 of the housing is transverse to the direction of the Contact movement in one piece.
- the abutment 25 must therefore when installing the Switching device inserted from the side under the contact pressure spring 24 become.
- For holding the abutment 25 are in the upper part 14 of the housing positive connections molded.
