A customer service closure includes a base having a plurality of indentations on one side for facilitating the mounting of a variety of communications apparatus such as protective devices. On an opposite side of the base there is provision for mounting the closure on a number of structures such as walls, horizontal and vertical conduits, pedestals, and mounting posts. Protection against environmental contaminants is provided by a cover which is slidably engageable with the base. The cover and base further include provisions for securing them to one another to prevent unauthorized entry.

Customer service closures

An insulation piercing slotted beam connector includes a central base portion which is bifurcated at one end. Each of the furcations has a chisel-like cutting edge at its tip which enables the terminal to pierce through insulation covering a conductor so that the insulation remains intact along an outer edge. The base portion also includes provision whereby the bifurcated end can advantageously laterally yaw upon engagement with the insulation covered conductor to properly align the terminal with an offset conductor for a gastight connection.

Insulation piercing slotted beam electrical connector

A connector block for terminating unprepared communication service wires is disclosed. Pairs of spaced-apart, laterally offset, quick-connect terminals make electrical connections with opposite sides of insulation covered electrical conductors comprising the service wire when the wire is inserted into the connector block and the terminals and conductors are urged into engagement with one another.
