CONTACT SPRING REPAIR
Alignment of the contact springs (pins) in the Patchboard receiver of the
Digalog Series 2040 Test System is critical. Misaligned or bent pins can cause
failures in the system. It is possible that one or more contact springs may
become damaged in one way or another. If the springs are bent, and the bend
is horizontal (lateral), the springs may be repairable. If the springs are severely
bent, or bent vertically, they must be replaced.
When damage to the springs is minor and
repairable, they may be straightened with
an Alignment Comb (Digalog part number
0000-2745) designed for this purpose.
When several contact springs of a single
row are out of position, straighten them
with the alignment comb to attain
uniformity. Use the comb as follows:
1. De-energize the system, and remove the Patchboard fixture to expose the
contact springs.
2. Determine the contact springs to be straightened. You can do this by
placing a non-metallic straight edge vertically along the row to be straightened.
CAUTION: Be sure the contact springs you are aligning are either all left
hand or all right hand springs.
3. Place the bottom edge of the teeth of the
comb between two vertical rows of contact
springs.
4. Place the bottom edge of the teeth against
the base of the contact springs in the row
adjacent to those being straightened.
5. Push against the top of the contact springs
with the comb. It may be necessary to bend
the contact springs beyond the normal
