ABSTRACT:
A plug-in connector to couple pneumatic, hydraulic, or vacuum lines to elements mounted on a printed circuit board is described. The connector employs a wedge shaped male unit that plugs into a female unit having a cut-out which receives the wedge shaped male member. The mated male and female units of the connector provide an intermediate passage that is normal to and connects with the inlet and outlet passages whereby the forces on the connector are such that no fasteners are needed to keep the mated parts from separating.
