Abstract
Abstract An electrical box for securing a sheathed cable extending along a support wall to a connector is disclosed, preferably for use in a local area network computer communications system. The connection box comprises a mounting base, a cover plate, and a connection box. The mounting base has pairs of smooth cylindrical posts of different height respectively formed along edges of the base. The sheathed cable extending through an opening in the connection box is clamped between one pair of posts by a clamping bar screwed against upper post ends. A method of temporarily positioning the cover plate carrying the connector to the connection box is also disclosed allowing an installer to use both hands to electrically connect the cable to the connector. In an alternate preferred embodiment, the connection box is secured to the mounting base without screws by means of anchoring feet and retaining lugs formed along common end portions of the base and connection box and a latch arm arrangement at opposite end portions of the base and box for securing the parts together in snap-fitting engagement. In accordance with a further preferred embodiment, the sheathed cable may be clamped to the mounting base by means of a pair of clamping jaws slidable along one edge of the mounting base within a slide track integrally formed in the mounting base upper surface.
