Abstract

A specially designed spanner wrench makes it possible to use screw-on connectors for coaxial disconnect panels used in array testers for semiconductor devices. The screw-on connectors provide a more positive connection and do not require the use of a separate retainer board as is the case with the previously used snap-on connectors.

Spanner Wrench for Use on Closely Spaced Coaxial Connectors

A specially designed spanner wrench makes it possible to use screw-on connectors for coaxial disconnect panels used in array testers for semiconductor devices. The screw-on connectors provide a more positive connection and do not require the use of a separate retainer board as is the case with the previously used snap-on connectors.

The many cables on a disconnect panel (Fig. 1) make it extremely difficult to secure them using conventional tools or fingers. The limited space between the individual cables makes their assembly or disassembly from the panel time consuming and does not assure a tight connection, especially of those toward the center of the panel.

A long, slim spanner wrench 1 (Fig. 2) was designed to fit over the female retainer nut 2 (Fig. 3) of the coaxial cable 3 (Fig. 3). The wrench has a protrusion 4 (Fig. 2) which fits over the retainer nut. The end of the wrench has an extended opening 5 (Fig. 2) which makes it possible to accommodate the end of the cable which is being connected or disconnected. This also affords the tool a cantilever effect which applies pressure to the retainer nut so it may be turned.

(Image Omitted)

The new wrench makes it possible to quickly and securely tighten the connectors or makes it simple to remove them, as required.
