THERMOPLASTIC ELECTRICAL ENCLOSURE

摘要

An electrical enclosure is made of a thermoplastic material such as a polycarbonate material. The enclosure includes a box and a lid hinged to the box along its back edge. A top edge of the box and a bottom edge of the lid are shaped to engage and hold a resilient seal when the lid is closed. The lid may be moved between an open position and a closed position. The lid is held in the closed position by a tongue and dog fastener arrangement. One of the lid and box has a dog that projects from the front edge of the box while a resilient tongue projects from the other of the box and lid. The tongue has an opening that receives the dog when the lid is closed in order to hold the lid closed. An extension of the tongue projects past the opening and at an angle to create a space for manual engagement to pry the tongue away from the dog when it is required to open the box. A pair of hasp members, one part of the tongue and the other part of the one of the box and lid from which the dog projects, are aligned with each other when the lid is closed. The hasp members have holes that permit a lock or other retaining pin to be inserted in order to inhibit unintentional opening of the enclosure. The enclosure includes external mounting flanges to secure the enclosure to a supporting structure. The enclosure also may include internal rails integrally formed with the box for mounting electrical components. No metal inserts are included in the enclosure.
