A modular distribution frame is disclosed which includes a module block having first and second parallel opposing rows of wire connectors. Apertures in the block provide access to the connectors. The wire connectors have a wire terminating end and a spring contact finger end. The spring contact finger end of opposing connectors extend into the apertures in releasable electrical contact. An overload protector element is provided adaptable for insertion into the aperture and extending between opposing spring fingers to electrically separate the fingers. The overload protector element includes circuitry to provide electrical connection between the opposing wire connectors through the element.

Modular distribution frame including protector modules adapted for break

A distribution frame comprising interconnect block modules for use in telecommunications is disclosed. The frame is front accessible for both wiring and test access. The structure incorporates a reversible wire guide to facilitate wiring of a module from either the right or left hand side of a particular mounting bracket. The individual modules incorporate an overload protector element which utilizes a printed circuit board as a primary contact structure. The individual modules also use split cylinder insulation displacement connectors which are readily accessible from the front of the module and terminate in spring fingers which make contact to the overload protector elements.

Modular interconnect block with protector structure

A test plug is disclosed for alternatively providing releasable electrical connection between a test lead and a first and second electrical contact where the first contact is a female contact and the second contact is a male contact. The plug includes a housing sized to be manually engageable and having a slot formed through a first end of the housing. A plunger is slidably disposed within the housing and slidable between an extended position and a retracted position with the plunger having a contact portion sized to extend through the slot and be received within the female contact when the plunger is in the extended position. The contact portion is further sized to be received within the housing when the plunger is in the retracted position with the slot being unobstructed to the insertion of a male contact. A first electrical contact point is disposed within the slot and yieldably biased into electrical connection with a male contact received within the slot. A conductor connects the first contact point to the test lead. The contact portion is provided with a deposit of electrically conductive material which is disposed to connect electrically with the female contact when the plunger is extended to the extended position with the electrically conductive material also in electrical contact with the first electrical contact point.
