ABSTRACT:
A sealed electrical device like a relay includes a support base, a relay device on the inner side of the support base through which extends longitudinally-exposed terminals for feeding current to the relay device, and a housing having a relay-enclosing portion, and a stepped intermediate portion forming a continuation of the device-enclosing portion and making a face-to-face sealing engagement with longitudinally and laterally outwardly facing surfaces on the support base so that there is no straight-on access of a water stream external to said housing into the interior thereof on the inner side of the support base from either a lateral or longitudinal direction. The intermediate housing portion terminates in a sealing skirt-forming end portion extending a substantial distance longitudinally beyond the sealed portion of the support base to act as a further barrier against the ingress of an external water stream into the interior of said housing on the inner side of said support base. The support base has longitudinally extending connector guide walls on the outer side thereof enclosed by the housing skirt portion. The housing is secured to the support base by interlocking means on the inside of the skirt portion and the outside of said longitudinally extending walls. Means are provided for interlocking the housing skirt portion with a releasable locking means on the connector unit.
