ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a connecting element for joining individual contactors to form a contactor combination.
BACKGROUND OF THE INVENTION
Connecting elements for contactor combinations have been part of the delivery program of contactor manufacturers for a long time. With the contactors used for this purpose, the magnet chambers are provided with grooves, e.g., dovetail grooves or T-grooves. The conventional connecting elements are positioned in the area of top-hat rail mounts of the contactor. In this way, the connecting elements are secured against falling out. When the devices are screwed onto a base plate, it is possible for the connecting elements to become dislocated and migrate as far as the base plate.
Due to the increasing miniaturization of contactors, in particular the reduction in overall width, the possible positioning of the coupling site is limited by the available space in the magnet chamber. If the coupling site is outside the engagement area of the top-hat rail, dislocation of the connecting element must be reliably prevented.
SUMMARY
An object of the present invention is to create a connecting element with which dislocation is reliably prevented, regardless of the position of the contactors in the magnet chamber and regardless of the type of fastening, e.g., top-hat rail mount or screwing onto a base plate. This object is achieved by a connecting element having the following features:
a) The connecting element has engagement sections for insertion into suitably shaped engagement grooves in the contactors.
b) The connecting element of the engagement sections is provided with catches serving to engage on the individual contactors after insertion of the engagement sections into the engagement grooves.
c) The catches are molded onto resilient outside surfaces of the connecting element.
