Description
~:~l6'~
Background of tlle Invention The present invention relates,in general to fusing in connec,tion with electrical devices, and pertains, more particularly, to a combination plug 5 and fuse holder preferably embodied in a single integral unit preferably constructed of a fire retard-ant plastic.
There have been recent requirements for the use '' of a fuse directly in connection with certain elec- r 10 trical appliances such as the requirement for fusing a C*ristmas light string. The usual technique for i,ncorporating the fuse is to provide a separate fuse and associated holder connected into the electrical cord at some position along its length. However, this 15 arrangement usually makes it relatively difficult to ',provide for replacement of the fuse in an easy manner. ' Accordingly, one object of the present invention is to provide a combination fuse holder and plug preferably provided in an integral unit and wherein 1, 20 the fuse is very simple to replace without requiring the disconnection of any parts.
Among other objects of the present invention is tlle object of providing a fuse plug in which the assembly of the fuse on the cord is facilitated at a 25 low cost without requiring wire stripping or notching.
In accordance with this invention the electrical cord is placed into the housing but without requiring an~
stripping or notching.
Among other objects of the present invention is 30 the object of providing a fuse plug in which the assembly of the fuse on the cord is facilitated at a ; low cost without requiring wire stripping or notching.
In accordance with this invention, the electrical cord r lS placed into the housing but without requiring any 35 ,stripping or notching.

s --Among other objects of the present invention is the object of providing a fuse plug in w}lich the assembly of the fuse on the cord is facilitated at a low cost without requiring wire stripping or notching. In accordance with this invention, the electrical cord is placed into the housing but without requiring any stripping or notching.
Another object of the present invention is to provide a combination plug and fuse holder which enables the ready addition of fuse protection to existing equipment or applicances virtually wi~hout the use of any tools. If an appliance or equipment is only provided with the usual plug and it is desired to provide fuse protection, then the combination plug and fuse holder r of this invention may readily be substituted in place for tile conventional plug. This thus then provides r the dual operation of a plug and a fuse with the incorporation of a single unit to the electrical cord.
A further object of the present invention is to provide a fusing arrangement for an electrical cord in wllich fuse ~eplacement is permitted only when the r unit is unplugged from an electrical outlet. Further-more, in accordance with this invention, the fuse can be replaced without disturbing any electrical contact points to the wire.
Still another object of the present invention is to provide a combination fuse holder and plug as an integral unit and one in which the electrical cord is ;~ not easily disengagable with the housing.
Another object of ~he~present invention is to provide a combination fuse holder and plug that is preferably in a single unit thus eliminating any separate two-piece unit. This is accomplished by making the end connector or plug embodied in a housing 35 that also forms a fuse holder.
' :: ~ r ~, Summa~ the Invention A constructlon in accordance with the present invention comprises a combination plug and fuse holder adapted for receiving a multi-conductor cord and includ-ing a first insulated housing member having a passage for receiving the electric cord and a pocket extending substantially parallel to the passage and adapted to receive a fuse. Contact means are provided for elec-trically coupling one conductor of the cord to one end of the fuse. First prong means are associated with the first insulated housing member for electrical coupling to the other conductor of the cord. A second insulated housing member includes means for permitting the separation apart of the first and second housing members and for further interlocking these members. A second prong means is associated with the second insulated housing member extending in parallel with the first : prong means but only in the interlocked position of the housing members~ The second prong means is provided for electrical coupling to the other side of the fuse.
More specifically, there is provided a combination fuse holder and plug preferably formed in an integral unit and preferably of a fire-retardant plastic material. This housing is preferably formed in three separate members including a base member, an overlying body member and an end member. The body member is hinged along an edge from the base member and the end member is similarly hinged from an end edge of the base member. The base and body members together define a channel for accommodating the electrical cord.
- Also, the base member has an elongated slot or pocket for accommodating the majority of the fuse. The fuse plug normally accommodates an elongated cylindrical buss fuse. One end of this fuse extends into an accommodating opening in the end member for contact by one of the :;
:
-, ~:~L~
- 4a -prongs. The other prong is supported from the body member having an inner end directly contacting one of the conductors of the electrical cord. The other conductor of the electrical cord contacts a further contact member that is engaged with the fuse. The electrical circuit is thus formed with the fuse in series with one of the conductor leads of the cord.
As previously mentioned, the separate members comprising the apparatus of this invention are hinged relative to each otherO In addition, means are provided for enabling the snapping together of these various members for the purpose of providing a unitary fuse holder and plug. The accommodating channel or pocket for the fuse is dimensioned so that the fuse will slide easily in the pocket but only when the end member is hinged away from the base and body members. Thus, for replacement of the fuse, the end member simply needs to be hinged open t~ expoee an end of the fuse which :

serted into the pocket and the end member may then be hinged from the base member and moved into a locked position to provide a unitary apparatus.

Detailed Description ReEerring now to the drawing, there is shown apre-ferred embodiment for the fuse plug of this in-vention. I'his device embodies ina slngle integral unit both an A/C type plug and a use holder. The housirlg comprising the fuse plug is readily separable preferably by hinging to permit easy replacement of the fuse. One of the advantages of the construction of this invention is that the fuse can only be replaced, ~
10 however, with the unit unplugged. The Euse holder of - ~ r this invention may be used with any appliance or the ''like electrical equipment especially those now re-quiring fuse protection directly in the electrical cord.
The plug-in fuse holder of this invention com-prises a housing that is made up of three separate r housing sections identified herein as base member 10, overlying body member 12, and end member 14. ~ach of these members are perfectly constructed of the same material SUC}I as a fire-retardant plastic. These different housing members interact primarily by means of elongated hinge lines between different of these members as explained hereinafter. This hinge ,line is defined by a relatively'thin plastic bridge between the difEerent members of sufficient thickness so as not to break but also sufficiently thin to function as a hinge.
In the drawing there is shown a hinge 16 along an elonga~ed edge interconnecting the base member 10 and , .
the overlying body member 12. Similarly, there is 30 provided a ilinge 18 at a bottom edge of the base member for hingedly interconnecting the base member 10 and the ,~, - , end member 14. ' ,, The base member 10 is of generally rectangular shdpe having an elongated channel or pocket 20 for r 35 accommoi~ating the ma~ority of the length of the fuse 22, .
r ~::
I`he fuse may be of many different types and amperage ratings. One fuse that may be employed is a buss AGG 7.
As depicted in the drawing~ the fuse includes metal end caps 23 and 24. The section of the fuse 22 including 5 the end cap 24 it is noted extends outwardly from the base member 10 into an accommodating slot 26 in the end member 14.
The base member 10 also has an upright wall 28 relatively centrally disposed along the member and 10 defining one side of the channel 20. The top surface r of this wall also forms a rest surface for one side of the electrical cord as described hereinafter. The elec-trical cord 30 may be a conventional type of cord having the two conductors 31 and 32. One of these 15 conductors makes contact with one end of the fuse while the other conductor makes direct contact with one of the r plug prongs as described hereinafter.
'~he body member 12 is also oE substantially rec-tangular shape. On its internal surface, there is pro-20 vided an elongated groove 36 that is open to the outside.
lhis groove has a width and a depth that is adapted to readily accommodate a conventional electrical cord. As noted in the drawing, the cord also rests upon the top surface of the wall 28 of the base member 10. At the 25 outer end of the groove 36 there is provided a tri-allgular ridge transversely across-the groove identified in the drawing as ridge 38. Similarly, there is a corresponding,ridge 40 that is extending outwardly from the base member 10. These are relatively small ridges.
30 llowever, when the base and body members are interlocked the tendency is for these ridges to grip the cord and ~ rclieve any strain on the contact points with the con-- ductors.
, ' :
.
rhe overlying body member also has a thin passageway for accommodating electrical prong 42. The hole in the body member is arranged so that the prong is tightly fitted in the body member. The prong has a lower r 5 pointed end ~ that is adapted to engage the conductor wire 31 when the base and body members are interlocked.
Very similarly, at the other end o-f the base and body members there is provided a contact piece 44 having a pointed end 45 that is adapted to pierce the other 10 conductor 3Z when the base and body members are inter-locked. The contact 44 also has a turned end 46 that is adapted to firmly interengage with the end piece 23.
of the fuse 22.
The base member 10 is provided with two upright 15 locking posts 50 which are adapted to pass through corres-pondingly positioned holes 52 in the overlying body member 12. ~ach of these locking posts has a barbed end so that when the body and base members are interlocked this barbed end engages with a top surface of the body 20 member to lock the base and body members in position.
The opposite side of these members is secured by means of the hinge 16. r As previously mentioned, the end cap 24 of the fuse extends into a slot 26 formed on the inside of the end 25 member 14. It is noted that the top wall 56 of the end member is adapted to fit substantially planar with ~:: `tllC top wall 58 of the body memb~er 12. This top wall also reccives a second prong 60 that is substan~ially similar to the prong 42 except that this is a longer 30 proTlg having a base 62 that extends into the slot 26 and that is adapted to electrically interconnect with the fla-t end of the end cap 24 of the fuse 22. Of L
course, when the end member 14 is hinged away from the basé member 10 then the contact between the fuse r 35 and the prong 60 is interrupted.
: .
~ : :
:: ~ - r ~ , .
The end member 14 is hinged along the hinge line 18 from a lower end edge of tlle base member 10. ~his hinging occurs by means of a thin plastic bridge between the different members permitting the hinging action.
After the base and body members are interlocked in the manner described previously, then tlle end member may then be interlocked with the body member. Thus, the end member hinges with the base member but locks to a closed position by interengaging with the overlying body member. -~
In this regard, the body member is provided with a locking - post 66 having a tapered edgc 68. To cooperate with this, t]le top wall 56 of the end member is provided with a thru passage 70 with an edge thereof interlocking with the tapered edge of the locking post. L
I:or replacement of a fuse, the end member is simply disengaged witll the locking post on the body member and the end member is hinged along the hinge 18.
When this hinging occurs, the force imposed by the base of the prong 60 is relieved and the fuse is essentially in a loose position in its accommodating pocket and can be easily withdrawn. A new fuse can ~`
then be inserted and the end member is rotated back r to its locked position. It is noted that because the two prongs are rotatcd away from each other to replace ; ~ 25 the fuse, this fuse replacement cannot occur with the pIug plugged in.
llaving described one preferred embodiment of the present invertion, it should now be apparent that numer-ous other embodiments and modifications are contemplated as Ealling ~ithin the scope of this invention. For examl)le, tile fuse plug can be constructed in different sizes and could be adapted for accommodating differentL
length or configuration fuses. ;~
