FUSE HOLDER Filed May 4, 1955 Patented Dec. 15, 1953 UNITED STATES PATENT OFFICE 2 ,662,953 FUSE DER Ray Barker, Wichita, Kans. Annl qa pnMav 1953, Serial 52 3 Cla m 1 This invention relates to a fuse holder and has among its objects the provision of a resilient or elastic hollow container of electrically nonconductive material having spaced contact members therein which are dispcsed'wi'thin' an electric conductor having portions extending into the container; the container having at least one opening in the wall thereof medially of the ends of the container for insertion therethrough of a fuse that is held under compression between and in engagement with the spaced contact m mbers by stress resigning troroan elongation of he container when'the fuse is forcibly inserted between the contact members of the conductor.

Another object of the intention resides in the provision of a resilient or elastic tubular-container for an" electricfuse di oosed'therein between spaced contacts of electric conductor .ex tendingftherein through the opposite ends of the container and which container is capable of being stretched to permit forcedinsertion of the ,fuse between thespacedcontacts, or the removal oi the fuse therefrom, through an accessible opening, or a pair of transversely aligned openings, in the body of the container.

Another object of' the invention is round in the provision of a fuse holder constructed-from .relsilient material, such as rubber, artificial or synthetic rubbr or certain flexible plastics, for the above-stated purposes [and to obviate shorting" or grounding of electricalcircuits in the event the holder accidentally comes inicontact with metallic structures or other .uninsulated electrical conductors.

The various features of novelty whereby the present invention'i's characterized will hereinafter h poi ted Pi with pa l r t i the claims, but, for a full understanding of the invention and of its objects and advantages, referonce may be had to the following detailed description taken in connection with the accompanyingdrawing,.whereinli Fig. l is'a side elevationof a fuse holder embodying my invention.

Fig. 2 is a side elevation of the fuse holder, turned ninety degrees on its longitudinal axis from that of Fig. 1, parts being shown in section for a convenience of illustration.

Fig. 8 is a longitudinal sectional View, taken on line 33 in Fig. 2, looking in direction of I the arrows.

Fig. 4 is a cross sectional view, taken on line 4-4 in Fig. 1, looking in direction of the arrows. The invention herein disclosed relates to a fuse holder that may be interposed in an electrical conductor and supported suitable position and location.

The invention finds embodiment in an elongated tubular and preferably cylindrical container I, said container being hollow and proe vided with closed perforated ends and molded or otherwise formed from material having elastic ,or resilient'and electrically insulating properties thereby in any such as rubber or flexible plastics.

The container i is provided with apertured ends 2 through which insulation covered electric conductors, orwires 3, extend. IntermedL ately of the ends 2 of the elongated bo'dy'o'f the container l, and located in diametrically op posite sides of the body, is a pair of elongated openings 46 and 5, said openings being provided for the purpose of inserting a conventional fuse ierethrough and into the container. Said openings further provide windows for visually inspecting the fuse B by observing the conditidn of its protective fusible link 1.

For electrically connecting each of the condue-tors 3 to the respective metallic end cap members 8 of the fuse vi3, the inner end of each conductor 3 is secured to a suitably shaped con-- tact member ,9, preferably conveXoconcave in formgthe QdnveX side preferably having a small flattened central portion 9 positioned in contact with alcorre'spoilding respective end {of the fuse, while the concave side of the member 9 engages an inner convex face of an end closure wall of the container I. Each contact member 3 has an axial aperture in which the insulationstripped end portion of the electric conductor 3 is suitably'seciuredfas by soldering or the like. The engagement of the contact member .9 with t e inn enside of its respective'container end 2 will resist the possibility of the contact member 9 pulling .through theapertured end 2 should undue forcebe applied to the conductor 3.

-Ih e contact members 9, with portions of their respective co'nductors '3 secured thereto, maybe positioned in place during the time of forming th i id t ip ii t i th n lqtbrs 3 wit their contacts "9 "may be inserted through one of the openings 4 or 5 of the container I and the conductors 3 threaded through the apertures in the ends 2, and then pulled until the contact members 9 come to engagement with their respective seats in the ends 2 of the container.

It will be understood that to remove a fuse, the container is stretched sufficiently, by gripping the container adjacent its ends to thus permit one end of the fuse to be swung outwardly to, the tension in the stretched container forced into engagement with the contact 9 of the other conductor 3. stretched after the fuse is inserted and its ends. engage both contact members 9 whereby sufficient stable contact is maintained between fuse 5 and contact members 9.

The body of the holder, With fuse inserted therein, protects the fuse from short circuits The container remains slightly or grounding out of electrical components coming in accidental contact therewith, and the fuse containing holder may be readily inserted in any electrical system.

The fuse equipped holder may be supplied with electrical conductors 3 of predetermined length for convenient installation.

While the invention as specifically described is at present preferably the manufactured structure, the same may be altered therefrom with respect to details of structure, form and proportion, and

other modifications may be made as lie within the scope of the appended claims;

I claim:

1. In a fuse holder comprising a hollow container of material having elastic and insulating properties, a pair of spaced electric contact members carried in the container, an electric conduc tor secured to each contact member and extending outwardly from the container, said container having an opening in a wall thereof for insertion therethrough of a fuse into said container, and a fuse held under compression between and in engagement with said contact members by stress resulting from an elongation of the container when the fuse is forcibly inserted between said contact members.

2. In a fuse holder comprising an elongated resilient hollow container of electrically insulating material, a metallic contact member positioned in the container adjacent each end thereof and adapted to be secured to an electrical con- D ductor extending into the container, a fuse in said container, said container having accessible means medially of its ends for permitting replacement of the fuse into the container, and said container being forcibly elongated when said fuse IS installed within the container between said contact members thereby urging said contact members into engagement with said fuse.

3.
