ADD-ON MTU ASSEMBLY FOR USE IN A TELEPHONE SUBSCRIBER JUNCTION BOX

摘要

An add-on MTU assembly (10) for a binding post array of a telephone junction box to interpose an MTU circuit unit between subscriber wiring and the utility's distribution cable. A first module (40) includes an MTU circuit unit (60, 290) therein having tip and ring wires (70, 72) extending to terminal housing subassembly (100), and having binding post wires (74, 76) extending to be attached to binding posts (20, 22). Terminal housing subassembly (100) includes a pair of terminals (112, 114) terminatable to ends of subscriber tip and ring wires (24, 26), and terminals (112, 114) are also electrically connected with tip and ring wires (70, 72) extending to the first module (40). Each of the modules (40, 100) includes a binding post clamp (44, 104) to be clamped onto a respective binding post (20, 22). The add-on assembly (10) is compact and flexible to be added onto a binding post array along with like others for other pairs of binding posts and fit into a confined space immediately surrounding the binding post array.
