Abstract

A fuse receptacle, an electrical fuse holder device in the form of a small plastic case which can be safely handled and with a removable cover to provide access to the fuses, also with a pair of standard external metal plug contacts on one end of the case, called front end, and a pair of internal metal receptacle contacts enclosed in the other end and which same contacts are so positioned in the main body of the plastic case that a pair of standard plug contacts similar to same on the front end can be inserted through access slots in the case into contact with the internal receptacle contacts. The external and internal conductors on each side can be eletrically connected inside the case by a fuse placed in fuse clips attached to the top of each of the conductor parts.

Claims

1. In a fuse receptacle, an electrical fuse holder device, to be used in connection with the standard receptacle and plug contact means between an appliance and a power source, comprised of a plastic case and a set of metal parts fixed in place therein, the plastic parts consisting of a main body, a bottom plate and a fuse cover, and the metal parts consisting of a pair of standard parallel external plug contacts of which about one-half the total length of each is fixed in the same main body, a pair of parallel internal receptacle contact parts enclosed and fixed in the other end of the same main body and spaced apart to receive a pair of standard plug contacts, a fuse clip fixed in contact with each of the same plug contacts and receptacle contacts, those parts of the same metal parts and those parts of same plastic parts, the main body together with the bottom plate cemented in place thereto, which constitute the self locking means by which the same metal contact parts are securely and rigidly locked in place in the same plastic parts.

2. In claim 1, in the said main body part, the pair of parallel plug contact main slots, the pair of parallel receptacle contact main slots, the sHort end slot and a bottom recess on each side of each of the same main slots, which same slots and recesses constitute the self locking means wherein the said metal contact parts are fixed in position, also in same main body part, the pair of access slots to the said internal receptacle contacts, also in same main body a bottom plate locating recess in the sides thereof, also a center barrier on the top surface of same main body.

3. In claim 1 the said bottom plate locking means whereby the metal parts are locked in place in the said main body part, and the raised edge locating means of said bottom plate.

4. A pair of parallel plug contact main slots and a pair of receptacle contact main slots identical to same as in claim 2, except that same slots also have self locking fuse clip recesses formed therein consisting of a pair of side clearance recesses and a pair of bottom locking recesses in each slot.

5. In claim 1 the said pair of plug contacts, formed of folded sheet metal, and the self locking means thereof consisting of a short end flange and a bottom flange on each side of the main body of each of the same plug contact parts.

6. In claim 1 the same pair of receptacle contacts, formed of sheet metal, each comprised of three parts, a channel shaped outer casing with a short locking means flange on the end of each leg thereof, a channel shaped inner casing with a short locking means flange on each side of one end thereof, and a leaf spring with a hook formed on one end by which means same spring is fixed to same inner casing part by crimping the same hook to one flange thereof.

7. A leaf spring identical to said leaf spring as in claim 6 except length from free end is increased one-half the length of the said inner casing part and that same length folded back to the concave side forming a double leaf spring.

8. A main body with fuse cover identical to a main body with fuse cover as in claim 1 except that the plane of the mating line between the fuse cover and the main body is about one-half the distance between the top surface of the main body and the bottom surface of the fuse cover top, wherein the parts below that same plane of separation are a part of the main body and the parts above are a part of the fuse cover.

9. A self locking fuse clip identical to fuse clip as in claim 1, except with an added spaced pair of legs of same width as, and extending below same fuse clip with a simple locking means hook on each end thereof.
