Abstract
Abstract A surge protection cartridge is disclosed which is compact, allows for surge protection devices to be inserted and removed by hand, is rugged, is easy to use and is economical. The cartridge includes a plastic housing, a series of tip and ring terminals mounted to the housing, a ground bar mounted within the housing, a guide strip frictionally mounted to the housing, two attachment clips and a cover. The guide strip is partitioned and includes surge protection device pads with three holes and funnel-like bordering surfaces around each hole to facilitate installation of the devices. The side walls of the housing are shortened to allow hand installation and removal of devices and the cover is used to protect the devices and maintain their connection even when the cartridge is roughly handled. The attachment clips connect to the housing, to a standard telecommunication frame and to a modular terminal block assembly.
