Crushed Tubing Coaxial Connector

In some instances when connecting one printed circuit to another, coaxial cabling is needed. This connector not only provides the coaxial feature, but also forms a resilient contact that permits easy connecting and disconnecting.

Two metallic tubes 10 and 11 are telescoped and separated from one another by a third tube 12 of insulating material. Outer tube 10 is cut back at 14 to expose the inner tube and insulation. The end of tube 10 is then flared at 9. An area 15 is compressed, flattening all three tubes. The remainder of the connector is flattened in area 16 at right angles to area 15 and then curved to form a spring contact.

The other end of tube 10 is stripped back to expose the end of tube 11 which is flattened at right angles, to area 16, to form contact 17. Block 20 of insulating material formed with pockets in it accommodates the lower half of area 15 of the connector and supports circuit board 22. Block 21, provided with pockets for the upper half of area 15, is bolted to block 20. Area 15 stiffens the connector while area 16 forms a resilient arm for the free end.

Tube 10 makes contact at the flared portion with land 23 that is connected by a plated through hole, to ground circuit 24 on the opposite face of printed circuit board 25. Inner tube 11 can be connected in any manner to a signal circuit or component. Spring contact area 16 engages ground circuits 26 on circuit board 22 and flattened contact 17 engages signal...
