Abstract
Two contactors are mutually interlocked via a blocking element which is arranged between the contactors. The blocking element interacts with guides on the contact supports of the contactors. The guides act directly on the blocking element. Only compression forces, but no tensile forces or shear forces, now occur in the blocking element, as a result of this and as a result of the blocking element being configured in a suitable manner.
Claims19
A contactor arrangement, comprising:
- two contactors;
- and
- a blocking element, wherein the contactors include guides, wherein the blocking element is in an intermediate position, permitting operation of either contactor, when none of the contactors are operated, wherein the blocking element is deflected from the intermediate position to a blocking position blocking operation of one of the two contactors thereby creating a blocked contactor, by a guide of an operated contactor upon one of the contactors being operated, the blocking position preventing operation of the blocked contactor, wherein the guide of the blocked contactor acts in an operating region on the blocking element upon attempting to operate the blocked contactor, wherein the guides act directly on the blocking element, wherein essentially only compression forces occur in the blocking element as a result of an attempt to operate the blocked contactor, wherein side surfaces of the contactors face one another, wherein the blocking element is arranged in a blocking element holder, wherein the blocking element holder is arranged between the contactors and wherein the blocking element holder is arranged at least partially recessed in the contactors.
A contactor arrangement, comprising:
- two contactors;
- and
- a blocking element, wherein the contactors include guides, wherein the blocking element is in an intermediate position, permitting operation of either contactor, when none of the contactors are operated, wherein the blocking element is deflected from the intermediate position to a blocking position blocking operation of one of the two contactors thereby creating a blocked contactor, by a guide of an operated contactor upon one of the contactors being operated, the blocking position preventing operation of the blocked contactor, wherein the guide of the blocked contactor acts in an operating region on the blocking element upon attempting to operate the blocked contactor, wherein the guides act directly on the blocking element, wherein essentially only compression forces occur in the blocking element as a result of an attempt to operate the blocked contactor, wherein side surfaces of the contactors face one another, wherein the blocking element is arranged in a blocking element holder, wherein the blocking element holder is arranged between the contactors, and wherein the contactors each include one front face and one rear face, opposite the front face, and wherein the rear faces and the blocking element holder end flush with one another.
A contactor arrangement, comprising:
- two contactors including guides;
- and
- blocking means for, in an intermediate position, permitting operation of either contactor when none of the contactors are operated, and for, in a blocking position deflected from the intermediate position, blocking operation of one of the two contactors, thereby creating a blocked contactor, upon one of the contactors being operated, the blocking position preventing operation of the blocked contactor, wherein the guide of the blocked contactor acts in an operating region on the blocking means upon attempting to operate the blocked contactor, wherein the guides act directly on the blocking means, wherein essentially only compression forces occur in the blocking means as a result of an attempt to operate the blocked contactor wherein side surfaces of the contactors face one another, wherein the blocking means is arranged in a blocking element holder, wherein the blocking element holder is arranged between the contactors, and wherein the blocking element holder is arranged at least partially recessed in the contactors.
