FREDERICK H. AYER, OF CHICAGO HEIGHTS, ILLINOIS.
ELECTRICAL CONNECTOR.
Specifieationof Letters Patent.
Patented Oct. 22, 1907.
Application filed February 23, 1907. Serial No. 358,782.
The object of the invention is to provide a structural shape of wire or rod which may be readily drawn by the use of ordinary drawing dies, and which when used in conjunction with a suitably channeled bonding pin or plug will complement the bonding pin and form in conjunction with the latter a practically solid body which will exactly fill and completely occupy a cylindric bore.
The invention will be readily understood from the following description, reference being had to the accompanying drawing, in which Figure I shows in side elevation a very common type of electrical rail bond formed of wire or rod of my improved cross-sectional shape; Fig. 2 is an end view showing on a larger scale the bonding wire; Fig. 3 is a plan view of a piece of the wire shown on the same scale as Fig. 2; Fig. 4 is a cross-sectional view of the bonding wire assembled in a bonding pin of suitable cross-sectional form for use therewith. Fig. 5 is a side elevation of the bonding pin shown in Fig. 4. Fig. 6 shows an application of the invention. v
Describing the said bonding wire or rod, the same, as clearly shown in the drawings, is triangular and equilateral in cross-section; each of the three sides thereof, as l, 2 and 3, being formed on an arc concentric with the angle opposed thereto. That is to say, the side one is formed on an arc concentric with the point 4, and the sides 2 and 3 formed on arcs respectively concentric with the points 5 and 6. The size of the wire or rod may, of course, be varied at will.
In use a section of wire cut off and formed into a bond,
as for example like that illustrated in Fig. I and designated 7, has its ends inserted in suitable apertures in the contiguous ends of the rails or other conductors to be electrically connected, and a tapered and channeled bonding pin, such for example as that shown in Fig. 5 and having the cross-sectional form shown in Fig. 4 and designated 8, is driven into the aperture alongside of each bond terminal in such manner that the latter rests within and occupies the channel of the bonding pin. The channel 9 of each bonding pin conforms in shape and dimensions to two sides of the bonding wire and the third side of the latter conforms to and rests flush with the cylindric or approximately cylindric exterior of the pin, as seen clearly in Fig. 4.
By reason of the peculiar cross-sectional form of the wire or rod the terminal parts of the bond will complement and exactly fill out the channels of the pins used to connect the bond to the rail and produce not only as perfect and electrical contact as can be had between separately formed metallic parts but at the same time form weatherproof joints which preclude access of air and moisture and thus prevent oxidation, electrolysis and deterioration.
An important advantage resides in the facility with which the parts may be assembled when connecting the bond to the rails, as well also as the facility with which a bond of any desired length may be made, i. e. cut off.
Obviously it. is immaterial which particular angle of the equi-lateral wire or rod is placed within the channel since the cross-sectional form is symmetrical, and it is further obvious that the length of the bonding wire or the distance to which the latter is inserted through the channel pin is likewise immaterial.
I claim as my inventiont A .hond wire or rod having the cross-sectional shape of a three-sided figure. each side of which is formed on an are described from the intersection ofthe other two sides.
