<p>The present invention relates to a magnetic yoke (12) intended particularly for electromagnetic coil (2) of a circuit breaker trigger mechanism (1) comprising a single part having the form of an enclosed jacket (13) encircling said electromagnetic coil (2) with a continuous transition (14) into a curved projection (15) for a fixed contact (16) and further extending backwards to said jacket (13) as a straight section (17) of an arcing contact (18). Portions of the enclosed jacket (13) that are in contact with each other, are interconnected by an entry (19) of one portion into another and in the region of the curved projection (15) for the fixed contact (16) as well as in the region of said curved projection (15) transition back to the enclosed jacket (13) said magnetic yoke (12) is narrowed symmetrical to the width thereof to the form of said arcing contact (18) and has, in that spot, side distance projections (20). An electrically conducting bridge (29) serving for interconnection of the fixed contact (16) and said electromagnetic coil (2) outlet (28) may be adjoined in the form of a splice bar to said arcing contact (18).</p> |
