Abstract
A connector assembly includes modules which intermate to interconnect electrical circuits between mother and daughter printed circuit boards. The modules are provided with resilient projections which latch on relative rotation of the modules, enabling the handling of resultant modular assemblies. High current carrying terminals of the modules have contact posts of different spacings and lengths from a contact point to assure equal resistivity to avoid hot spots for high current. A polarizing key locking feature is provided by a snap ring including a slot to permit engagement and disengagement by a simple tool such as a screwdriver.
Claims8
A modular connector assembly for the distribution of power to a printed circuit board comprising;
- pairs of first and second matable individual connector modules, the first connector module of each pair having a pluggable mating face and a board-engaging face and the second connector module of each pair having a complementary pluggable mating face and a board-engaging face, each first individual module of respective pairs being provided with means to link itself with adjacent first modules to form a composite connector body, and each second individual module of respective pairs being provided with means to link itself with adjacent second modules to form a complementary composit connector body;
- and
- at least one pair of first and second polarizing modules, said first and second polarizing modules being linkable with respective adjacent first and second connector modules, each said first and second polarizing module including a dielectric housing member having a multifaced cavity therein, said first polarizing module further including a polarizing projection having a corresponding multifaced surface for receipt in said first cavity in different rotational positions corresponding to the opposition of respective different faces of the cavity and projection, a forward end of the projection being free of a mating face of the housing member for mating engagement with a corresponding multifaced cavity of said second polarizing module of the pair, the other end of the projection being formed with a groove adapted to receive locking means therein, and a locking means adapted to be inserted through an access opening in the housing to engage said groove to lock the projection axially in the housing in any one of the rotational positions, a one end portion of the locking means extending from the housing for engagement by a release tool to withdraw the locking means from the groove to release the projection for withdrawal from the cavity and rotation to another polarizing position.
A pair of polarizing modules comprising:
- first and second modules each having a dielectric housing member having a multifaced cavity therein, the said cavity of said first member being adapted to receive a polarizing projection therein;
- a polarizing projection having a corresponding multifaced surface for receipt in said first member cavity in different rotational positions corresponding to the opposition of respective different faces of said first member cavity and projection, a forward end of the projection being free of a mating face of the first housing member for mating engagement with a corresponding multifaced cavity of the second module of the pair, the other end of the projection being formed with a groove adapted to receive locking means therein;
- and
- locking means adapted to be inserted through an access opening in the first housing member to engage said groove to lock the projection axially in the first housing member in any one of the rotational positions, a one end portion of the locking means extending from the housing for engagement by a release tool to withdraw said locking means from the groove to release the projection for withdrawal from the first member cavity and rotation to another polarizing position.
