Abstract: A terminal block for terminating one or more exchange wires to one or more service wires has a housing including a plurality of separate chambers each of which are accessible to a service wire through a wire access port. The terminal block includes an access jack including a service wire junction contact provided within a service wire junction contact slot, an exchange wire junction contact provided within an exchange wire junction contact slot and an earth junction contact retained within an earth junction contact slot. Exchange wires are terminated to respective exchange wire junction contacts in the terminal block and the corresponding stub cable is permanently secured thereto. One or more service wires are terminated and conductively connected to a service wire junction contact. A linking module is provided which, when inserted into the access jack, forms a conductive connection between the service wire junction contact and the exchange wire junction contact.

Abstract: A protected terminal block has a housing (10) having a plurality of test ports (18) and a plurality of electrical contact elements (40), each of which includes a test lead (48) which is accessible through a test port (18). The electrical contact elements are configured in the housing and connected to an exchange wire which is secured to a stub cable. A protection module retainer (140) is secured to a side of the housing (10) proximate the test ports (18) to form a plurality of retaining cups (142) adapted to receive a protection module (100). A grounding strip (150) is secured to ground and retained between the protection module retainer (140) and the housing (10) proximate the test ports (18), the grounding strip (150) having a plurality of integral ground connectors (158). A protection module (100) is provided having a protector (116) which is connected to a pair of terminal block contact elements (102) and a ground connector (160).

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.

Abstract: A cable enclosure for enclosing electrical cable splices, typically telephone cables. An elongate housing having first and second housing members joined together along one edge for movement between housing open and closed conditions, and an elongate header for attachment to a messenger cable, with the housing members being closable about the header. A suspension system is provided for supporting the housing members from the header when in the open condition providing free access to the cables during the splicing operation. The housing members have replaceable end plates for handling various numbers of cables through each end plate.

Abstract: A switching assembly for selectively connecting telephone cable to a test set or the like. A mounting panel provides connectors for receiving two twenty-five pair telephone cables, and a third connector for receiving another twenty-five pair cable. A set of switches provides for connecting the third connector to either the first or second connector. The switches are mounted in a row on a printed circuit board and are driven by a sliding actuator plate carried between the switches and the mounting panel, with a rotating knob driving the actuator plate to control the switches, and indicating which of the first and second connectors is being connected.

Abstract: A cap shoe system for making electrical connections between a plurality of conductors in one cable and a corresponding plurality of conductors in a connector module of a connector which includes an index strip, the connector module, and a cap. The cap has access holes for contact pins carried by the cap shoe which has a slide member that is retractable to provide for entry of the contact pins through the access holes in the cap into electrical contact with the respective conductors in the connector module. The cap shoe body is formed of two molded shell sections with projecting bosses for locating the contact pin housings. The slide member is a unitary molding and carries corresponding adjustable shims and locking clips for engaging the connector module.

Abstract: A crimp-type cable shield bonding device for electrically interconnecting the shields of two sheathed and shielded cables each having an outer protective sheath and an underlying shield which enclose a bundle of conductors. The bonding device includes two tubular clamps respectively connectible to adjacent ends of the two cables. Each tubular clamp comprises a generally semicylindrical outer portion adapted to fit over the outer protective sheath at one end of one of the cables and a generally V-shaped inner portion within such outer portion, with its apex extending toward the outer portion. The inner portion of each tubular clamp is insertable between the shield and the conductors at the corresponding end of the corresponding cable with its apex extending toward the shield. The inner portion of each tubular clamp has teeth extending toward the outer portion of such tubular clamp and adapted to penetrate the shield of the corresponding cable.

Abstract: A cap shoe system for making electrical connections between a plurality of conductors in one cable and a corresponding plurality of conductors in a connector module of a connector which includes an index strip, the connector module, and a connector-module cap, and/or for making electrical connections between a plurality of conductors in another cable and a corresponding plurality of conductors in a bridge module forming part of the connector and including a bridge-module cap. The connector-module and bridge-module caps have access holes for connector-module and bridge-module contact pins respectively carried by connector-module and bridge-module cap shoe bodies having connector-module and bridge-module slide members which are retractable to provide for entry of the connector-module and bridge-module contact pins through the access holes in the connector-module and bridge-module caps into electrical contact with the respective conductors in the connector and bridge modules.
