Abstract
Abstract The invention provides an iduction generator comprising a plastic injection-molded housing having a port and one or more pole shoe(s) associated with a permanent magnet. A plastic bobbin inserted into the port and having a coil wound thereon which, through soldering eyelets, is connected to two contact tags in communication with an outwardly guided cable. A mounting member, with the port at the end thereof facing the soldering eyelets being closely sealed by a lid welded to the housing. To provide an induction generator that is easy to manufacture and that insures a substantially improved operation, the port of the housing at the end thereof facing away from the soldering eyelets is closed by a bottom integrally formed with the housing and the pole shoe or shoes along with the associated permanent magnet are integrated in the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
An induction generator comprising: (a) an injection molded housing of plastic material provided with a port; (b) at least one pole shoe; (c) a permanent magnet associated with the at least one pole shoe; (d) a bobbin made of plastic material accommodated in the port, a coil wound on the bobbin and connected through soldering eyelets to two contact tags, the contact tags being in communication with an externally guided cable; and (e) a mounting element on said housing displaced from said port; (f) the end of the port facing the soldering eyelets being tightly closed by a lid welded to the housing, the end of the port facing away from the soldering eyelets being closed by a bottom integrally formed with the housing, and the pole shoe and the associated permanent magnet being integrated in and sealed within the housing with the housing bottom extending over said at least one pole shoe.
Claim 2
Dependent Claim
153 words
An induction generator comprising: (a) an injection molded housing of plastic material provided with a port; (b) at least one pole shoe; (c) a permanent magnet associated with the at least one pole shoe; (d) a bobbin made of plastic material accommodated in the port, a coil wound on the bobbin and connected through soldering eyelets to two contact tags, the contact tags being in communication with an externally guided cable; and (e) a mounting element on said housing displaced from said port; (f) the end of the port facing the soldering eyelets being tightly closed by a lid welded to the housing, the end of the port facing away from the soldering eyelets being closed by a bottom integrally formed with the housing, and the pole shoe and the associated permanent magnet being integrated in and sealed within the housing with the housing bottom extending over said at least one pole shoe.
