Abstract: A rectangular loading coil case has front, back, side and end panels, with cable entry and exit provided in one end panel, and with a support structure attached to, for example, the front panel and comprising rods extending across the case with a series of beams extending in opposed pairs and supported on the rods by spacer members positioned on the rods. Assembled magazines of loading coils are supported on the beams, each magazine supported at one end by one of a pair of beams and supported at the other end by the other of the pair of beams. A plurality of magazines are carried by each pair of beams, to form a layer. The number of layers can vary.

Abstract: Loading coils for communications cables are preloaded into magazines and prewired to terminal strips carried on the magazines. A magazine comprises a length of material, typically extruded or molded plastic material, of a channel shaped cross-section to accommodate the coils flat and side-by-side. End caps fit on each end of the magazine to retain the coils in position and also serve as mounting means in a casing. The terminal strips are mounted on an extension of one wall of the channel shaped cross-section. The preassembled magazines are then assembled in the casing a higher packing density is obtained, and the prewiring of the coils to the terminal strips provides effective orientation of the coils relative to each other to give good electrical and electronic separation and reduced cross-talk.

Abstract: A loading coil assembly comprises a casing having discs at each end. At the inlet end a support disc is mounted on and spaced from the end disc and a plurality of assembled magazines holding loading coils is attached at one end of each magazine to the periphery of the support disc. A similar support disc interconnects the other ends of the magazines, the magazines extending in a circle about the casing axis. Further circles of magazines can be added by providing one or more annular rings attached to the end disc carrying the support disc, for attachment of the magazines at one end, and also interconnecting the other ends of the additional circles of magazines by annular rings. The conductors can be fed along spaces between adjacent magazines. The casings vary in size according to the number of circles of magazines.
