Abstract

A tuning fork contact is considered to be an optimum device for connecting components to pins. Sometimes, it is required that a module, to be plugged onto the pins, be central to the pin grid arrangement. The module itself may not have the space available for containing the tuning fork contacts.

Tandem Contact

A tuning fork contact is considered to be an optimum device for connecting components to pins. Sometimes, it is required that a module, to be plugged onto the pins, be central to the pin grid arrangement. The module itself may not have the space available for containing the tuning fork contacts.

A tuning fork 10 is provided that is split into two sections and arranged to straddle the module 12. The pin entry portion 14 of the straddled fork is bridged to enable a combined spring force to be applied against the mating circuit board pin 16. Lobes 18 are shown molded into the side of the module to position and strain relieve the fork contact. A selected clearance between the position lobes 18 and the fork slit 20 provides a self-aligning feature to absorb pin to pin manufacturing tolerances. A small spacing is provided between the bottom of the module and the end or bridged portions of the tuning fork contact so that the module will not interfere with the pin insertion. Drawing B shows a side and front view of the tandem contact and illustrates the dimpled opening 14 or contact surface for receiving the pin 16 to which it is to be plugged.
