Method of fitting a coil onto a bobbin. |
摘要 |
<p>The invention relates to a method of fitting an overload coil (44) for a circuit breaker onto a bobbin assembly (24). The overload coil is preformed into a helical coil (44) with a pair of terminals (16, 17) and a coil sub-assembly (76) is formed by attaching electrical leads (42) to the terminals of the coil. Separate base and top halves (26, 28) of a split bobbin are assembled so that the pre-formed coil of the coil subassembly is held captive therebetween. A sensing tube (18) is fitted through an aperture extending axially through the assembled split bobbin, and the sensing tube is mounted onto a magnetic cradle. Different top halves, such as a voltage coil top half (46) and a high inrush top half (60) may be fitted into a common base half. The invention extends to a bobbin assembly for a circuit breaker, as well as to an overload coil sub-assembly (76). <IMAGE></p> |
