Abstract

This article describes a hook assembly for connecting anodes to electrical bus bars in electroplating applications. The hook assembly is self-aligning and contacting on power bus bars allowing automatic loading and unloading of anodes with no manual operations or safety concerns. The assembly consists of an upright plate 1 with a welded U- shaped bracket 2 and support gussets 3. The anode basket, bar, etc., is attached to the assembly at position 4. The assembly is lifted to and from the bus bar 5 via connections at position 6. A cam action lever arm 7,8,9 with two pivot points 10 is connected to the U-shaped bracket. During operation, contact is made between the upper part of the lever arm and the bus bar.

Self-Aaligning Electrical Hook Assembly

       This article describes a hook assembly for connecting
anodes to electrical bus bars in electroplating applications.  The
hook assembly is self-aligning and contacting on power bus bars
allowing automatic loading and unloading of anodes with no manual
operations or safety concerns.  The assembly consists of an upright
plate 1 with a welded U- shaped bracket 2 and support gussets 3.  The
anode basket, bar, etc., is attached to the assembly at position 4.
The assembly is lifted to and from the bus bar 5 via connections at
position 6.  A cam action lever arm 7,8,9 with two pivot points 10 is
connected to the U-shaped bracket.  During operation, contact is made
between the upper part of the lever arm and the bus bar.  The pivot
points and weight of the anode force flush contact of the lower part
of the lever arm and the power bus bar with good wiping action.  A
copper (or other metal) pad 11 can be placed on the upright plate for
minimal electrical resistance with the bus bar and improved wiping
action.  The electrical resistance between the bus bar and hook
assembly is sufficiently small to allow in excess of thousands of
amperes current flow while meeting the small voltage drop
requirements (circa 1-5 volts) of typical electroplating power
supplies.
