The following MUST be complied when attaching balance wires to taper pins. Most balance wires are extremely small (i.e. 30 AWG). Taper pins used in wind tunnels are not designated by the manufacturer for this size of wire. The following is an acceptable alteration. NEVER solder wires to taper pins.
Very Small Wires, #26 AWG or Less:
Mechanical strength is important -- Fold back wires (after stripping), cover with shrink tubing as shown.
|
Correct |
|
|
Put insulation all the way into rear crimp. For very small wires (#32, #36 AWG) two layers of shrink tubing may be necessary for proper crimp.
|
Incorrect |
|
|
Do not let bare wire stick out beyond "rear" crimp. Wire is weaker without shrink tube. The wire may break at 3:00AM during a tunnel run!
Following is the accepted method for attaching designated wire size to the AMP P/N 41666 taper pin. NEVER solder wires to taper pins!
#22 and #24 AWG Wires:
|
Correct |
|
|
Proper taper pin crimp requires insulation be gripped by the "rear" crimp.
|
Incorrect |
|
|
Do not let bare wire stick out beyond "rear" crimp. The wire will break at 3:00AM during a tunnel run
