摘要： A connector is provided for selectively connecting or disconnecting a stripper rubber to or from drilling head equipment such as a bearing assembly. A generally cylindrical adapter connected to the equipment defines a primary bore accommodate a down hole tubular. One or more cam pin bores, adapted to house one or more cam pins, are positioned radially around the adapter substantially parallel to the primary bore. One or more cam lock bores adapted to house one or more at least partially rotatable cam locks, are offset from the pin cam bores such that each cam pin bore partially intersects a corresponding cam lock bore to form an apertaure through which the cam lock engages the cam pin. One or more cam pins are connected to the stripper rubber; and one or more at least partially rotatable cam locks house in the cam lock bores of the adapter optionally engage or disengage the pin cams to respectively connect or disconnect the stripper rubber to or from the equipment.
