Abstract
A bobbin for an electrical coil is described having a main winding space for electrical wire and at least two separate further winding spaces for terminating the wire wound on the main winding space. The or each further winding space has a groove in which a number of terminating wire coils can be wrapped. The groove is breached or gapped so that the wire coils wrapped in the channel bridge the breach and can be wholly or partially soldered together at the bridging portions to form terminal connections to the wire on the main winding space.
Claims9
A reed relay assembly, comprising:
- a bobbin having a hollow interior;
- first and second spaced apart flanges integrally formed on said bobbin for defining therebetween a first main winding space, at least one of said flanges having at least one slot for defining a wire passageway;
- third and fourth flanges integrally formed on said bobbin and axially spaced from said first and said second flanges for defining a second and a third annular termination winding space;
- a selected length of electrical wire wrapped a preselected number of turns around said first winding space to provide a main coil and wrapped a preselected number of turns around said second and said third annular termination winding spaces to provide termination windings the individual turns of which are electrically joined together to provide first and second electrical terminals for said main coil;
- and
- a reed switch disposed through said hollow interior and within said main coil.
