Abstract

High-density pin connections are established with low-insertion force, while positive retaining action is provided through self-contained forces. Low-cost components are used and relatively relaxed tolerances are possible, while providing dual contacts for each pin.

Cam Activated Multicontact Connector

High-density pin connections are established with low-insertion force, while positive retaining action is provided through self-contained forces. Low-cost components are used and relatively relaxed tolerances are possible, while providing dual contacts for each pin.

Base or contact holding block 10 retains rows of pairs of contact springs 13. A cam screen 12 and a lever tool 14 which is used to move cam screen 12 in a plane parallel to 10, provides the remainder of the receiver portion for the connector. Cam screen 12 has a series of slightly tapered cams such as 15A, 15B and 15C at each contact position, and is positioned between the dual- contact springs 13. Lateral movement of cam screen 12 by lever 14 opens the contact springs to receive the pins 16 of module 17, as is shown for 13A and 13B.

In the open position, the connector presents a low-insertion force to pins 16 although some pressure will generally be required to seat the modules. However, this rubbing action further ensures positive contact between the contacts and pins 13 and 16. After pins 16 are seated, lever 14 moves cam screen 12 in the opposite direction closing the contacts, as are shown at 13C and 13D. As shown, all connectors 13 would be either open or closed, but 13A and B have been shown open and 13C and D closed for explanation purposes.

Each cam 15 has tapered side surfaces 18 which force contacts 13 apart when moved in one direction by lever 14 but, w...
