Seals for an electrical connector

摘要

An electrical connector assembly includes a receptacle connector (10) matable with a pin header (122). The pin header (122) includes a cavity (126) in which a gasket seal (202) is located. The seal (202) includes a rim (214) that is thicker than a central section (204) surrounded by the rim. The rim bulges inwardly when subjected to elevated temperatures so that excessive stresses are not imposed on the mated connectors. The seal (202) is rectangular and the portions (203, 205) of the seal rim (214) on the shorter end sections are wider than most of the rim along the longer sides. Sections (207 and 209) adjacent a central opening (212) are also wider than adjacent portions of the longer side of the seal rim (214). These wide section prevent the rim from rocking when subjected to compression and prevent the seal from ballooning next to the inside of the rim. Leakage when the seal is subjected to elevated temperatures is thus prevented.
