Abstract: A modular telecommunications terminal block system includes one or more terminal blocks (10) which may be repeatedly installed and removed from a mounting rail (24). Each terminal block (10) employs a housing (12) having a telephone exchange wire carrier and a service wire carrier within the housing. An exchange to be connected to the terminal block (10) is inserted through an opening (36) in the housing and into the exchange wire carrier (20) which is movable between an open position and a closed position. By manually pressing the exchange wire (20) in the closed position, or by installating the terminal block (10) onto the mounting rail (24), the exchange wire is terminated to an exchange wire contact element (170) within the terminal block (10). A service wire is separately terminated within the terminal block and engages a service wire contact element (66, 68).

Abstract: A telecommunications terminal block employs a housing having a number of separate dielectrically isolated chambers disposed therein. Service wires to be connected to a splice cable are inserted into a chamber through openings in the housing and into a movable wire carrier member disposed within the chamber. An actuator member drives the carrier member from a first position, at which the wires are inserted, to a second position where the wires engage a contact element which electrically couples them to the splice cable. The carrier member moves within the chamber so as to allow an electrically insulating medium within the chamber to flow around the carrier and maintain a constant volume of the medium within the chamber. Loss of insulating medium is thereby avoided during connection and reconnection of the service wires allowing improved protection from environmental factors such as moisture, chemicals and other contaminants.
