Abstract
A holder for an electromagneticcoil assembly comprised of joined mirror symmetric E core halves has two bracket pieces which are disposed adjacent to joined legs of the E core halves, each bracket having a pair of bores therein for receiving at least one retainer rod. The rod extends through the brackets and an alignment bore or groove in the core halves. In one embodiment of the holder a retainer plate having bores in registry with the bracket bores also receives the retainer rod, with nuts applied to threaded ends of the retainer rod to exert a uniform retaining pressure along opposite faces of the core halves to maintain a substantially constant core air gap and maximize vibration resistance.
Claims10
In an electromagnetic coil assembly consisting of opposed abutting E core halves each having an end face and two outer legs and a centrally disposed inner leg, and a hollow coil bobbin which receives said central legs and is disposed between said halves, a holder for said assembly comprising:
- two brackets disposed adjacent to said outer legs of each core half, each said bracket having a pair of spaced bores;
- at least one retainer received in said bores in said brackets, said retainer terminating in two threaded ends;
- a means in said E core half legs for receiving and aligning said retainer,
- whereby said retainer extends through said brackets and said means in said core half legs to hold said halves between said brackets;
- a pair of nuts received on said threaded ends of said retainer for applying uniform retaining pressure to said halves in cooperation with said brackets;
- and
- at least one vertical leg respectively depending downwardly from each bracket, each said vertical leg carrying means thereon for attaching said vertical leg to a circuit.
