Housing assembly for an electrical apparatus

摘要

A housing assembly is provided for use with a television surveillance camera or the like. The housing includes an extruded stationary base with identical frame-shaped front and rear fixed members, and a removable extruded cover which latches to the front and rear members. A television camera inside the housing may receive optical images through the front frame member and transmit these images via cables leaving the housing through the rear frame member. A molded rubber end cap is adapted for detachable connection to the rear frame member, sealing out dust and contaminants when in place. The detachable end cap includes dustproof openings for the entry of cables into the rear of the housing with projections for strain relief incorporated into the openings. The openings are further connected by a slit in the rubber end cap, permitting cables to be inserted through the end cap without removing terminal connecting members. The periphery of the end cap is also formed with reinforcing gussets to provide shock protection at the rear edges of the housing assembly. The extruded base further includes tracks for supporting a planar camera platform and permitting the platform to slide longitudinally with respect to the base. Specially designed quick release clamps permit the platform to be secured to the tracks when the camera is properly positioned relative to the front frame member of the housing.
