Abstract
A synthetic resin (plastic) housing resistant to corrosive environments and especially adapted to receive electrical or mechanical devices or components, consists of two parts which are joined together with an interposed seal. According to the invention, the two parts have different depths so that each of the parts can be stacked with others of like kind and both of the parts are provided with mounting elements for the selective disposition of the electrical devices or units thereon which transmit force to a support for the housing without stressing the latter.
Claims12
A housing for a device to be sealed from the environment, said housing comprising:
- at least one housing part formed from synthetic resin material and having a mouth formed with a rim, lateral walls extending away from said mouth and a bottom wall remote from said mouth;
- a seal engaging said rim;
- mounting means on said bottom wall for the selective attachment of said device in said housing in said housing part substantially without applying strain to said housing part, said lateral walls being provided with sealable openings affording access to said device;
- and
- a support adjacent the bottom of said part, said mounting means including mounting elements passing through holes formed in the bottom wall of said part for connecting said support to said device, and including a member traversing each hole and extending entirely therethrough, one end of said member bearing against said support and being anchored thereto by a first bolt, a rail bearing against said member in said housing part and spaced from said bottom wall, said rail being adapted to support said device, whereby said housing part is not stressed by said mounting means.
A housing for a device to be sealed from the environment, said housing comprising:
- two housing parts formed from synthetic resin material and open toward one another, each housing part having a mouth formed with a rim, lateral walls extending away from said mouth and a bottom wall remote from said mouth;
- a seal interposed between said rims;
- mounting means on said bottom walls for the selective attachment of said device in said housing in one of said housing parts substantially without applying strain to said one of said housing parts, said parts having different depths and each being stackable with like housing parts, said lateral walls being provided with sealable openings affording access to said device;
- a support adjacent the bottom of said one of said parts, said mounting means including mounting elements passing through the bottom wall of said one of said parts for connecting said support to said device, said bottom walls being formed at corners thereof with respective pedestals traversed by throughgoing bores, said mounting elements traversing said bores, bores of the housing which are not traversed by said elements being provided with blind plugs sealing the interior of the housing against the exterior thereof, each of said housing parts being formed along an external surface of the respective bottom wall with a polygonal recess registering with the respective bore, each mounting element including a threaded bolt having a flat head of polygonal configuration received in the respective recess and a threaded stud projecting into the interior of the housing engaged by a nut, said mounting means further comprising mounting rails secured to the respective element by the respective nut, said rails forming a frame and including first rails connected to said elements and second rails extending transversely to said first rails and connected thereto, said rails being of channel configuration and receiving T-shaped bolts for attaching said rails together and said device to said rails.
