Application April 19, 1939, Serial No. 268,804

2 Claims.

This invention relates to a fuse mounting, and

has for the primary object the provision of a device of this character which includes improved fuse terminal clips which will permit fuse changing to be easily and quickly carried out should a fuse burn out and which will efficiently grip the terminals of the fuse to prevent arcing when in use and consequently prolong the life of the clips as well as the terminals of the fuse and tends to check corroding.

With these and other objects in-view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a. front elevation illustrating a fuse invention.

Figure 2 is a sectional view taken on the line 22 of Figure'l, showing one of the clips.

Figure 3 is a perspective view illustrating the bifurcated portion of one of the clips and its attaching plate.

ing the terminal of the fuse tightly against the seat I4 and against the portion [2, thereby establishing an eflicient electrical connection between the clip and the terminal 'of the fuse which will prevent arcing and tends to check corrosion.

A clip of the character described and shown in the drawing is easily actuated to free the terminal of a fuse therefrom and to permit the reinstatement of a terminal of a fuse therein when desired. Also, it will be seen that due to the construction of this clip the bifurcated portions l2 and It as well as the seat I4 may be readily cleaned of corrosion.

The set screw I6 in its head portion may be provided with an annular groove [9 to receive the bifurcated portion it of the wedge ll thereby rotatably connecting the set screw to the wedge mounting constructed in accordance with our- Figure 4 is a wedge element for coaction with the bifurcated portion in gripping a terminal of a fuse,-

Referring in detail to the drawing, the numeral 5 indicates a panel mounting constructed of insulated material and ,apertured to receive fasteners forsecuring said panel on a Supp rt. Clips 6 are mounted on the panel 5 by screws or like fasteners 1 and are arranged a selected distance apart to receive the terminals 8 of a fuse 9, it being understood that the clips are constructed of conductive material and the fasteners I are employed for connecting electric leads tothe clips.

Each clip includes an attaching plate It on which is formed an enlargement ll. including converging portions l2 and I3. Formed on the inner face of the portion l2 inwardly of the free end thereof is a shoulder ll acting to form a seat for limiting the inward movement of the terminal of the fuse in the clip. The portion I3 is bifurcated and opening into the last-named bifurcation is a screw threadedsocket l5 formed in the enlarged portion II to receive a setscrew IS. A wedge element I1 is adapted to enter between the portions l2 and "and in contact with the terminal of the fuse and has a bifurcated portion l8 disposed at right angles thereto through which the set screw it extends. By

threading the set screw into the socket ii the wedge element ll will-be drawn tightly inwardly between the bifurcated portions 12 and llforccausing the wedge to follow the movement of the set screw.

It is believed that the foregoing description, when taken in connection with the drawing, will fully set forth the construction and advantages of this invention to those skilled in the art to which such device relates, so that further detailed description will not be required.

What is claimed is:

1. A fuse clip comprising an attaching plate including an enlarged portion, said enlarged portion being cut-away to form converging portions and one of said converging portions having a bifurcation, said enlarged portion having a screw threaded socket opening out into the bifurcated portion, a shoulder formed on one of the converging portions to form a seat for a fuse terminal, a wedge element engageable with the fuse element and the bifurcated converging portion to force the fuse terminal against the other com verging portion and the seat, and a set screw connected with said wedge element and threaded into said socket.

2. A fuse clip comprising an attaching plate including an enlarged portion, said'enlarged portion being cut-away to form converging portions and one of said converging portions having a bifurcation, said enlarged portion having a screw threaded socket opening out into the bifurcated portion, a shoulder formed on one of the converging portions to form a seat for a fuse terminal, a wedge element engageable with the fuse element and the bifurcated converging portion to force the fuse terminal against the other converging portion and the seat, a bifurcated portion formed on said wedge element and overlying the bifurcation of the converging portion, an a set screw extending through the bifurcation of the wedge and threaded into the socket.
