Abstract:
A magnet coil (1), a housing, said magnet coil is disposed in an interior of said housing (6), said housing has a circumferential wall (7) and a bottom (8), and the coil (1) is electrically insulated from an outside of said housing by insulation material (11), the magnet coil has two contact terminals (5) leading to the outside from the housing, said two contact terminals are enclosed over a portion of their length by insulating material (11, 15), and which lead with their regions surrounded by insulating material through openings (12) in the bottom (8) of the housing (6) and have an electrical connection outside the housing, in which the insulation of the magnet coil (1) and of the contact terminals (5) with insulating material (11) is formed by spray-coating on all sides, which is simultaneously sprayed onto the inner walls of the housing and completely fills up the openings (12) in the bottom and closes them and positions the coil in a predetermined position inside the housing (6), the bottom (8) has a third opening (17), through which a rod-like part (25) can be introduced from the outside into the interior of the housing (6), in conjunction with the contact terminals (5) the part is supported on stops, the magnet coil (1) is kept stably spaced apart from the adjoining housing walls in an intended position inside the housing (6) during the spray-coating process and the part is removed again after the conclusion of the spray-coating process, and the third opening (17) is likewise filled and closed by insulating material (11), the openings (12, 17) receiving the contact terminals (5) and the rodlike part (25) are disposed such that the rodlike part and the contact terminals together produce a stable three-point support.
