7 Claims.
This invention relates to an electrical junction device for the purpose of joining a plurality of wires carrying electrical current to or from a machine, switchboard, or some other electrical instrument.
It is the object of my invention to provide an electrical junction device which will enable a maximum number of wires to be brought together at the junction point in the smallest possible space and at the lowest cost.
Other and further supplementary objects will be seen from a study of the specification taken in connection with the annexed drawing wherein:
Figure 1 is a plan view of one form of my improved junction device, a part of the cover and number plate being removed.
Figure 2 is a side elevation of Figure 1.
Figure 3 is a bottom plan view of Figure 2.
Figure 4 is a section on the line 44 of Figure 2.
Figure 5 is a section on the line 5-5 of Figure 2,
Figure 6 is an enlarged view, part in section and part in elevation, showing certain details of the junction device. 1
In the various views wherein like numbers refer to corresponding parts, I is a block of insulating material which has a plurality of cross or transverse bores 2, within which are positioned metallic connectors 3. As will be seen from Figure 2, the bores 2 are arranged in a plurality of spaced rows and the holes themselves are arranged in staggered relation, one to the other, in the respective rows. By this arrangement thegreatest number of connectors 3 can be assembled in a giv'en size of insulating block, at the same time giving sufficient insulation between the walls of the adjacent bores.
The connectors 3 are hollow or provided with holes therethrough to receive the bared ends 4 and 5 of insulated conductors or cables 6 and I. As will be seen from Figures 2 and 6, the connectors 3 have the holes therein preferably eccentric so as to provide a thin wall 8 which may be indented as at 9, the indentation 9 acting as a stop for the bared ends 4 and 5 of the said conductors. The ends 4 and 5 are engaged by their respective screws l0 and II which are positioned in holes l2 provided in the block I.
As shown in 'Figure 1, the connectors 3 are preferably alternately ofiset, and likewise, the
This also inthe screws l0 and II. Also as shown in Figure 1, the bores for the connectors 3 are made so as keep moisture out of the connection and lessens corrosion and electrolytic disintegration at the connector. 10
Where a plurality of taps are desired to be made from one feed wire coming to the junction device, the bottom thereof is made with a channel I3, in which a metallic plate I4 is positioned, beingheld in place by screws l5 which go into 00- operative connectors 3 and are so positioned therein, as indicated in Figures 3 and 4, as to act, in each case, as a stop for the conductor ends, similar to the indentation 9 of Figure 6. By making the plate M of sufiicient length, as many taps may betaken off from one lead wire as are desired.
In covering the holes I2, I use a designation strip l6 over which is positioned a transparent plate H, the same being held to the block in any satisfactory manner as by screws l8. As shown in Figure 1, the block I may be formed at one or both ends with lugs l9 having screw-holes 20 therein for mounting purposes, or the block I may be provided at one or both ends with bosses 2| on its lower surface and mounted by a screw-hole 22 from an under-support; or the combination of the two may be used as shown in Figure 2. As a matter of fact, the block may be formed to fit any desired mounting so that the junction device may be used in an outlet box for socalled BX cable, or may be mounted to act as a terminal block for motors and generators; or arranged for any other type of mounting. It follows, of course, that the junction device may be made with any number 40 of bores and supplied with their respective connectors to'suit conditions; for example, for certain classes of work there may be as many as two,
three and four dozen connectors mounted within the block, while for a motor only two or three connectors will be required. By making the blocks l with mounting bosses such as 2|, contact with the mounting surface area is reduced and the possibility of moisture collecting on the 50 block is thereby largely eliminated.
From what has been said, it will be understood that various changes may be made in the mounting arrangement of the block and the parts carried thereby, without departing from the spirit of the invention and the scope of the appended claims.
