Abstract
A solenoid is provided having an improved connection arrangement. The solenoid includes external wires that are coupled to internal solenoid components via terminals. Further, a sealed solenoid is provided having a housing overmolded onto a solenoid subassembly. External wires can be coupled to the solenoid after overmolding. The solenoid may also include a cavity for receiving at least one of electrical component. The solenoid may also include a powdered metal core.
Claims16
A solenoid comprising:
- a bobbin;
- a core wire positioned about at least a portion of the bobbin, the core wire forming a coil;
- a housing positioned about at least a portion of the coil;
- a lid coupled to the housing, the lid and housing defining an interior area;
- an external wire extending from outside the housing into the interior area;
- a cavity positioned on the housing in the interior area, the cavity positioned adjacent the external wire and sized to accept at least one electrical component;
- a first channel and first recess on the housing in the interior area, the first channel extending longitudinally on the housing to accept the external wire and the first recess extending from the cavity to the first channel;
- and
- a second channel and a second recess on the housing, the second channel extending substantially parallel to the first channel, the second recess extending from the second channel to the cavity, wherein the cavity is positioned between the first and second channels.

A solenoid comprising:
- a bobbin;
- a core wire positioned about at least a portion of the bobbin and forming a coil, the core wire having first and second terminal ends;
- a housing positioned about at least a portion of the core wire, the housing defining an opening providing access from an exterior side of the housing to the first terminal end;
- an external wire extending from outside the housing;
- and
- a wire-to-wire terminal having a first end extending at least partly into the opening in the housing and having a generally V-shaped inner surface to provide contact with the first terminal end of the solenoid coil wire and a second end having a generally V-shaped inner surface to provide contact with the external wire, the wire-to-wire terminal providing an electrical connection between the first terminal end and the external wire.
