Method for connector contacts

Disclosed is a method for connector contacts. Benefits include improved module retention and improved design flexibility.

Background

              Conventional connectors are 0.9 mm in pitch. They have retention latches that have a lever arm below the module. Activation of the arm causes the retention mechanism to engage when the module is inserted. The lever arm protrudes into an area where contacts could be added if the lever arm were not required (see Figure 1).

              Conventional methods of adding contacts either increase the pitch or increase the connector length. These options add cost and require additional silicon surface area.

Description

              The disclosed method retains the module by inserting a pin into either a notch in the module or a hole near the edge of the module (see Figure 2). No lever arm or other feature is required to actuate the retention feature, ensuring connection security. The latch is part of the molded connector body and does not require any additional parts. As a result, additional silicon surface area is available for additional connector contact without increasing the length of the connector or increasing contact density or pitch.   

              The latch mechanism is attached to the side of the connector housing and does not interfere with connector contacts. Latches could be located on the same side of the connector or on opposing corners.

Advantages

              The disclosed method retains the module more securely than conventional methods.
