Tool Enables Proper Mating of Accelerometer and Cable Connector 
The problem: 
To design a tool that can be used in conjunction 
with a torque wrench to fasten accelerometer cable 
connectors to accelerometers without damaging the 
components or permitting them to work loose under 
sustained, high-level vibrations. 
The solution: 
A tool that supports the accelerometer in axial 
alignment with the cable connector and permits tight-
ening of the accelerometer to the cable connector 
with a torque wrench.
How it's done: 
The accelerometer cable connector is secured finger-
tight to the accelerometer.This assembly is then placed 
in the tool, with the accelerometer mounting stud held 
in the support bracket of the tool and the connector 
nesting between the contoured jaws. The bracket sup-
ports the accelerometer in axial alignment with the 
cable connector and prevents side loading and possi-
ble fracture of the mating connector. Hand-grip pres-
sure is applied to the tool to clamp the cable con-
nector and prevent it from turning while the specified 
(continued overleal)
