N V EN TOR. wim? f' Maf GOL/bq /ffwwff Patented Apr. 21, 1953 UNITED STATES PATENT GFFICE 2,636,096 FUSED CIRCUIT PLUG-IN RECEPTACLE Frank Di Blasi, Cedarwood Park, N. J. Application May 9, 1951, Serial No. 225,332 1 Claim. (Cl. 200-1155) This invention relates to a fuse plug and receptacle.
It is an object of the present invention to provide in a plug of the multiple type a fuse to protect the electrical system at the plug from appliances or xtures that may be faulty or which would overload the circuit unduly and whereby to localize the trouble and to eliminate the need for going to the basement or remote place to replace the main fuse.
It is another object of the invention to provide a multiple receptacle plug wherein the spring engaging formations for the plugs of the appliances are of a long strip extending through the plug body and wherein the fuse element is disposed centrally of the body and connected to one of the plug terminals and spaced from a plug terminal extending from one of the strips.
Other objects of the invention are to provide a fuse plug with multiple receptacle outlets which are of simple construction, inexpensive to manufacture, has a minimum number of parts, compact, easy to assemble and eiiicient in operation.
For a better understanding of the invention, reference may be had to the following detailed description, taken in connection with the accompanying drawing, in which:
Fig. 1 is a perspective View of the fuse plug and receptacle embodying the features of the present invention.
Fig. 2 is an enlarged perspective view of the receptacle as viewed from the side thereof having the prongs which extend into the room receptacle.
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.
Referring now to the figures, I represents an insulating body which is recessed on one face, as indicated at II, to contain terminal strips I2 vand I3. Each strip extends the full width of the insulating body and has a plurality of prongs I 4 which respectively extend through slots I6 in the insulating body. The prongs on the strip I3 are indicated at I4. The strip I 2 has a laterally extending portion I1 which is secured to the body I 0 by a screw I8 and outwardly from which there extends prong I9. Screws and 2| further secure the strip I2 in place upon the insulating body.
Also in the body I0 is a recess 22 in which may be disposed a fuse 23. A terminal clip 24 receives one end of the fuse 23. This terminal clip 24 is integral with a prong 25 aligned with the prong I9. 'Ihese prongs I9 and 25 enter the wall receptacle.
has a clip 29 thereon for receiving the other end of the fuse 23.
As illustrated in Fig. 1, a plug 3I of an appliance having prongs 32 can be inserted into the front face of the insulating body I0 so that the prong 32 thereof enters the slots I6 and engage respectively with the spring portions I4 and I4.
An insulating sheet 33 fits into the recess I I and under an inwardly extending ange 34 extending from the side thereof, Fig. 3. The prongs I9 and 25 extending through this sheet 33.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as dened by the appended claim.
