Dual probing tip system

摘要

A dual probing tip system uses a slot and rail system to provide variable spacing and lateral and axial compliance of the probing tips mounted on first and second support members. A movable base member is secured on a frame with the base member having a rack of linear teeth and a pair of rails angled toward the front. First and second intermediate carriers each have a slot that engages one of the angled rails. Each of the carriers has stanchions that receive a thumb wheel pinion gear mounted on a shaft. The pinion gear mates with the teeth on the base member for movement of the carriers. Each support member has an axial slot that mated with an axial slot on each one of the carriers. Each support member has a compression spring which allows axial compliance of the support members.

1. A dual probing tip system comprising: a base member movably mounted on a frame with the base member having first and second rails formed on a top surface thereof with the rails angularly disposed toward one end thereof; first and second intermediate carriers with each intermediate carrier having a bottom surface and a top surface with the bottom surface having a slot formed therein angularly disposed toward one end thereof for mating with one of the first and second angularly disposed rails of the base member such that movement of the moveable base member in one direction causes the distance between the first and second intermediate members to close and movement in the other direction causes the distance between the first and second intermediate members to open, wherein the each of the base member and the first and second intermediate carriers has a long axis and a front end and a back end with the rails of the base member angularly disposed relative to the long axis toward the front end thereof and the slots of the first and second intermediate members angularly disposed relative to the long axis toward the front end thereof, wherein each of the first and second intermediate carriers further comprises a rail formed on the top surface thereof parallel to the long axis and first and second support members with each support member having a long axis, bottom surface and a top surface with the bottom surface having a slot formed therein parallel to the long axis for mating with one of the rails on the top surface of one of the first and second intermediate carriers.
