Abstract
An electric terminal fitting intended to be interposed between a terminal plate and a terminal screw of an electrical outlet and hold an end of a conductor wire in place for electrical connection, the fitting including a two prong member fitting opposite sides of a terminal screw, and having wire retainer elements for placing the end of a conductor wire in position for electrical contact with the outlet. The fitting may be arranged to include a cover having an insulation surface which may be folded over the terminal screw to prevent shorting or grounding of the terminal screw. Also, the fitting may be formed of plastic material and maintain an electrical connection directly between the wire and the terminal plate or the terminal screw.
Claims11
An electric terminal fitting adapted to be interposed between a terminal plate and attaching screw to receive the stripped end of a conductor wire, said fitting comprising:
- a. a slotted plate element for receiving the shank of an attaching screw;
- b. at least one folded marginal element forming with the screw shank and plate element a guide passage dimensioned to receive an exposed conductor wire;
- the proportions of the guide passage being such as to clamp the wire upon tightening the screw;
- c. and a tab element extending from the plate element and foldable over the head of the screw, the tab element having an insulating surface to guard against electrical contact with the head of the screw.
An electric terminal fitting adapted to be interposed between a terminal plate and an attaching screw to receive the stripped end of a conductor wire, said fitting comprising:
- a. a metal plate element having a slot extending therein from one end to receive the shank of the screw;
- b. an integral tab element extending from the opposite end to aid in manipulating the plate element into the space between the terminal plate and the head of the screw;
- c. opposed folded marginal elements forming with the screw shank a pair of guide passages adapted to receive the exposed straight ends of conductor wires in tangential relation to the screw shank to retain the wire ends in place during tightening of the screw and securing the wire ends;
- d. the plate element and tab element being foldably connected and the tab element being of sufficient length as to be folded over the head of the screw;
- e. and a covering of insulation on the tab to guard the head of the screw against electrical contact.
An electric terminal fitting adapted to be interposed between a terminal plate and an attaching screw to receive the stripped end of a conductor wire, said fitting comprising:
- a. a plate element having a slot intersecting one end to receive the shank of the screw;
- b. a folded element at a margin of the plate element including means for placing the end portion of the conductor wire for retention and electrical connection between the terminal plate and the wire upon tightening the screw;
- c. a tab continuing from the plate element to aid in manipulating the plate element into position, the tab being flexible and dimensioned to fold over the head of screw and includes a surface of insulating material to guard the head from electrical contact.
An electrical fitting adapted for use with an attaching screw of a terminal plate for connecting the stripped end of a conductor wire, comprising a plate element having a portion for receiving the wire in generally parallel relation to the plane of the plate element, the plate element having a frame and releasable flap element for overlying the attaching screw with access through said frame for manipulating the screw, and at least the exterior of said frame and flap being electrically insulated.
An electric terminal fitting formed of insulation material and adapted to be interposed between a terminal plate and an attaching screw to receive the stripped end of a conductor wire, said fitting comprising:
- a. a plate element having a slot intersecting one end to receive the shank of the screw;
- b. a folded element at a margin of the plate element including means for placing the end portion of the conductor wire for retention and electrical connection between the terminal plate and the wire upon tightening the screw;
- c. and a screw cover means continuing from the folded element over the head of the screw and including a latachable and flexible central flap to provide access to the screw head and to cover the screw head.
