Abstract

A probe 1 is designed for use in connection with a card 2 that is to be probed. The principle feature of probe 1 is that it is relatively compact in the direction h, i.e., in the direction perpendicular to card 2 so that it can be connected to a card that is mounted on a machine in close proximity to other components or similar cards.

Card Probe

A probe 1 is designed for use in connection with a card 2 that is to be probed. The principle feature of probe 1 is that it is relatively compact in the direction h, i.e., in the direction perpendicular to card 2 so that it can be connected to a card that is mounted on a machine in close proximity to other components or similar cards.

To accomplish this, probe 1 has two side bars 3 and 4 provided with slots that receive the edges of card 2. A support member 5 connects the outer ends of 3 and 4 and is provided with a slot 6. Probe 1 also has blocks 7 and 8 mounted on member 5, each block having a part engaged with slot 6 so that blocks 7 and 8 can be moved to different positions along member 5. Contact assemblies 9-11 are mounted on block 7 and contact assemblies 12,13 and 17 are mounted on block 8.

Each of contact assemblies 9-13 is similar so that only one will be described in detail. Relative to assembly 9, each assembly has a rod 14 slideably engaged with the block. A knob 15, connected to the outer end of rod 14, provides means for manually moving the contact assembly and also allows electrical contact to be made by external implementation with the probe. The inner end of rod 14 is connected to a pivoted contact member 16 which establishes the electrical contact between probe 1 and the desired element of card 2.

Contact assembly 17 is slightly different in that it has a coaxial tube 18 slideably mounted in block 8. The outer conductive layer of tub...
