Abstract
In one aspect, there is disclosed a solenoid having a bobbin with a core wire positioned about the bobbin to form a coil. A power supply wire is connected an end of the core wire and a frame is connected to the bobbin. An overmolded housing surrounds the core wire, the frame and a portion of the power supply wire.
Claims21
A solenoid comprising:
- a bobbin;
- a core wire forming a coil about at least a portion of the bobbin;
- a power supply wire electrically coupled to an end of the core wire;
- a frame secured to the bobbin, the frame including a first end portion extending adjacent a first end of the coil, a second end portion extending adjacent a second end of the coil, and a longitudinal portion extending from the first end portion to the second end portion;
- and
- an overmolded housing surrounding the core wire, the frame, and a portion of the power supply wire.

A method of forming a solenoid comprising the steps of:
- winding a wire around a bobbin to form a coil;
- electrically coupling a first end of the wire to a power supply wire;
- inserting a portion of a core into an opening at a first end of the bobbin such that the coil encircles the portion of the core;
- attaching a frame to the bobbin such that a first end of the frame contacts the core and a second end of the frame contacts a portion of the bobbin adjacent a second end of the coil;
- and
- overmolding a housing about the coil, the frame, the connector, and a portion of the power supply wire.
3 more elements
A solenoid comprising:
- a bobbin having a securing protrusion;
- a core wire forming a coil about at least a portion of the bobbin;
- and
- a frame secured to the bobbin, the frame including a first end portion extending adjacent a first end of the coil, a second end portion extending adjacent a second end of the coil, and a longitudinal portion extending from the first end portion to the second end portion, the longitudinal portion including a slot for receiving the securing protrusion to couple the bobbin to the frame.
