ABSTRACT:
An improved sealable connector has a geometry which effects reliable sealing upon assembly. The connector is useful, for example, for connecting a pressure sensor to a fuel pump accumulator in a fuel injection system. The connector includes a male member, a female member, and an annular seal disc which compressibly seats between the male and female members. The male member has a tip with a flat annulus at an innermost radius surrounding a fluid-delivery bore. A frustoconical section of the tip extends radially outwardly from the annulus, sloping away from the plane of the annulus at about 5.degree.-15.degree., for example. The female member has a cavity shaped to receive the male member, the cavity having a bottom defined by a flat annular seat surrounding another fluid-delivery bore. The seal disc is compressed between the flat seat of the female cavity and the planar/frustoconical tip of the male member. Axial compressive loads on the disc are concentrated under the planar annulus such that the disc has a radially-inward zone of plastic compression adjacent to the fluid-carrying bore, this plastic compression zone being radially-outwardly surrounded by an elastic compression zone.
