DOUBLE ENDED TERMINAL Filed Aug. 1, 1946 /nvenf0r Gusf0veFB0/7r By his attorneys Patented Dec. 12, 1950 DOUBLE -ENDED TERMINAL Gustave F. Bahr, Fairficld, Conn, assignor to The Bead Chain Manufacturing 00., Bridgeport, Conn, a corporation of Connecticut Application August 1, 1946, Serial No. 687,554
1 Claim. 1
This invention relates to electrical terminals and more particularly to double-ended terminals of the type usually secured in panel boards or other supports so as to project on both sides thereof and it is an object of this invention to provide a terminal of the type described of improved construction which can be readily and cheaply manufactured and applied.
In the drawings:
Fig. 1 is a view in elevation, partly broken away, of a terminal in accordance with this invention, the terminal bein shown enlarged and inserted but not secured in a panel board open- Fig. 2 is a view similar to Fig. 1 showing the terminal of Fig. 1 secured in a panel board open- Fig. 3 is a view in elevation, partly broken away, of a portion of a terminal in accordance with this invention but of modified construction; and
Fig. 4 is a view in elevation, partly broken away, of the complete terminal partl shown in Fig. 3.
As shown in Fig. 2 of the drawings, a terminal in accordance with this invention may consist of a tubular member I having shoulders or collars 2 and 3 formed integral therewith and of such diameter as to prevent passage of the terminal through the opening in the panel board 4. As shown in Fig. 1, the terminal is formed with the collar 2 of such diameter as to prevent passage of the terminal through the opening in the panel board 4 and with an enlargement 3a which fits the opening in the panel board. The terminal is secured in the panel board, after insertion in the opening, by staking or swaging the enlargement 3a to form the collar 3 in engagement with the panel board so as to secure the terminal in position.
The terminal shown is formed with enlargements 5 and 9 at opposite ends and with cylindrical portions 7 and 9 of different diameters, the enlargement 5 being of a size to pass through the opening in the panel board 4 while the enlargement 5 is of a greater diameter.
The terminal shown in Figs. 3 and 4 is formed in two tubular portions, the portion A shown in Fig. 3 comprising a cylindrical portion 10 having an enlargement II at its free end, an integrally formed shoulder I2 adapted to be engaged with the panel board i, a cylindrical portion [4 fitting in the opening in the panel board 4 and an end l5 which is stapled, spun over or otherwise suitably engaged with the panel board to secure the portion A in the opening in the panel board. The portion B comprises a tubular member having a cylindrical portion 16, an enlarged end 11, an integrally formed shoulder 18 and a substantially cylindrical end part I9 of such diameter as to be secured by a press fit in the cylindrical part I4 of the portion A.
The terminal I and tubular portions A and B may be made from strip stock which is formed into a tube and then shaped into the terminals and the terminals severed on a machine of the type shown in the Goodridge and Gagnon Patent No. 1,087,876 of February 17, 1914.
What i claimed is:
A double ended tubular electrical terminal comprising two tubular portions adapted to project beyond opposite sides of a support, one portion projecting through and being adapted to be secured to the support on both sides by integral parts, in combination with a reduced cylindrical part in the other tubular portion press-fitted into the first tubular portion, said two tubular portions being of substantially the same diameter, and terminal enlargements on said two tubular portions.
