Junction box for electric and telephone cables - has two part shell assembly to hold end clamps in place and to provide facilities for injection of sealing compounds

摘要

The junction box is to protect electric or telephonic cable joints, and is formed by screwing together two half shells (1,1a) which at the same time secures clamping jaws (11,etc.) which hold the two cables at the two entries to the box. A groove is cut in the joining faces of both halves of the box and when assembled these grooves form a channel into which an insulating grease may be injected through an inlet provided for this purpose. The clamping jaws fit into slots (14,etc.) in the ends of the junction box and are mfd. from a flexible thermoplastic material into semicircular discs having concentric grooves cut in their faces to allows, ready sizing of the cable entry holes. An adhesive tape (20) is wrapped round the cable where the jaws grip it and sealing compound may be injected between the jaws to ensure complete watertightness of the assembled junction box.
