Abstract
The rotation of a power control arm on a fuse box is used to rotate a contact, sequentially disconnecting power to a fuse and spreading the tensioned jaws on a fuse clip to reduce the force needed to remove a flat fuse terminal from the clip.
Claims4
A fuseholder comprising a pair of tensioned opposed jaws defining a clip for the flat end of fuse and a contact electrically connected to the jaws and rotatable to create an electrical connection to a power terminal, characterized by:
- means on the contact for spreading the jaws as the contact is rotated to a first position at which the electrical connection to the power terminal is broken.
A fuseholder comprising a pair of tensioned opposed jaws defining a clip for the flat end of fuse and a contact electrically connected to the jaws and rotatable to create an electrical connection to a power terminal, characterized by:
- means on the contact for spreading the jaws when the contact is rotated to a first position at which the electrical connection to the power terminal is broken;
- the contact comprising a first contact surface for engaging the electrical contact and a second surface that is positioned between the jaws, the first and second surfaces being angularly disposed around an axis of rotation of the contact;
- and
- the second contact surface having a thickness greater than the thickness of the flat end.
