Abstract: The present invention relates to two modules containing electronic equipment, one relatively small, and one relatively large, that will be physically connected and used for extended operation in an environment where the ambient atmosphere contains moisture filled air or some other specified environmental contaminant. An absorber such as desiccant of a prescribed amount is contained within at least the relatively large module to control the absolute humidity and/or environmental contaminants within each module during extended operation in the ambient environment. Permeable wall portions are placed in the region between the relatively small module and the relative large module to allow for moisture and/or other specified environmental contaminants to pass from the relatively small module to the relatively large module. As such, the lifespan of the small module can be extended.

Abstract: Connector including a housing including a resilient portion provided with a cavity, connectors mounted in the cavity, the resilient portion deformable to increase access to the cavity to facilitate insertion and mounting of the connectors in the cavity, the connectors for mechanically and electrically engaging a first pair of terminals to which an incoming telephone line is connected and a second pair of terminals to which a telephone subscriber line is connected to mount the connector to the pairs of terminals and to electrically interconnect the incoming telephone line with the telephone subscriber line, a telephone circuit is provided in the connector which is connected to the connectors for connection to one of the lines or to both of the lines; alternate connector includes test terminal assemblies for the external testing of the incoming telephone company line and telephone subscriber line and a telephone circuit mounted internally of the connector without dismounting the connector from a connector block

Abstract: In a terminal connected to a distribution cable composed of wire pairs corresponding to communication lines, the wire pairs are disposed in an array across index strips. Termination of a selected wire pair corresponding to a communication line is achieved by mounting an insulation displacement connection (IDC) connector on one of the index strips. In the mounting process, the connector makes electrical contact with the selected wire pair. Drop wires may then be connected to the IDC connector, and brought into customer premises to realize the communication line. Unterminated wire pairs are available for termination at another terminal. Advantageously, using one or more terminals to distribute the wire pairs in accordance with the invention obviates, among others, the need for a prior art feeder distribution interface used in the traditional wire pair distribution.

Abstract: Enclosure for electrical switching equipment including electrical control or display devices (21) supported on a wall (23) of the enclosure, being accessible from the outside, a processing or control unit (20) for these devices which is housed inside the enclosure, and an electrical interface device (1) between the devices (21) and the unit (20), the interface device (1) being composed of a housing (10) comprising a body (11) that houses a printed circuit board and encloses a row of connection terminals (30) and a connector (61) to connect the printed circuit board to the devices (21) and to unit (20) respectively, characterized in that the interface device (1) comprises an attachment part (12a) installed on the inside of the enclosure wall (23) close to the devices (21), and the terminals (30) on the device (1) are of the quick fit type.

Abstract: The interface card consists of a circuit pack containing the line or trunk circuitry and a face plate connected to one side of the circuit pack. A first connector is located on the side of the circuit pack opposite the face plate for connecting the line card to the backplane of the switching system or other network element. A second connector is provided on the face plate for connecting the circuit pack to the cable plug of the cabling. To disconnect the connector, an ejection mechanism is provided on the face plate of the interface card. The ejection mechanism slides relative to the face plate to force camming surfaces into engagement with abutment surfaces on the cable plug thereby forcing the cable plug perpendicularly away from the face plate. Thus the plug is removed without damaging the pin connectors. A locking device can be optionally provided on the ejection mechanism to lock the cable plug into engagement with the pin connector to prevent inadvertent disconnection.

Abstract: A frame structure for mounting telecommunications equipment including a frame, a plurality of sealing covers, a plurality of fasteners, and a plurality of wire protective sleeve. The frame having a base, two support frames, and an upper frame. A receiving recess is provided to accommodate transmission conductors (optic cables, electric cables or lead wires) of telecommunications equipment. A positioning recess formed between the plate bodies at the upper and lower covers of the inner side of the sealing covers and the fastening plates allows the sealing covers to be mounted over the edge of the inner lateral plates of the opening of the receiving recess on the support frames. A fastener is then passed into a hollowed hole of the outer lateral plate on the sealing cover and further into a fastening hole, with the plate body of the sealing cover being pressed downwardly. A press element is then pressed into a fastener body to secure the connection.

Abstract: A configurable I/O panel assembly includes an upper and a lower I/O panel (connector plate), and a cover plate. A plurality of upper I/O panels is provided, from which the upper I/O panel is selected. Similarly, a plurality of lower I/O panels is provided, from which the lower I/O panel is selected. The cover plate is selected from a plurality of cover plates. Openings are formed in the upper and lower I/O panels for receiving cable connectors. Typical connectors include, but are not limited to, 50-pin connectors, RS-232 connectors, 9-pin D-sub connectors, RJ-45 jacks and BNC connectors. Grounding and other signal conditioning circuitry for the connectors are provided to protect against EMI radiation.

Abstract: An enclosure (10) for junctions of telephone service wires (18,19) and a stub cable (16) includes a rear panel member (20) and a front cover (100) adapted to be slid downwardly to expose the interior of the enclosure for wire interconnection and servicing. Wire-receiving openings (40,42) of the enclosure are organized in linear arrays and are sealed by a pair of elastomeric strips (80,90;44,46) held against the enclosure wall by bracket members (50,48), with one strip (90) having small diameter holes (92) for just fitting around a wire, and the other (80) having slits (82) which remain closed if no wire is inserted into a particular opening, with both the small diameter holes and slits aligned between the enclosure openings and openings (52) through the bracket members.

Abstract: A telephone jack panel assembly suitable for modular digital installations which facilitates connection at a period of time when the frame upon which it is installed is already congested by previously installed connectors. As contrasted with conventional construction, the disclosed panel is provided with a rearwardly extending housing, which mounts plural multi-contact connectors which are interconnected to corresponding multi-contact jacks mounted upon the free ends of incoming telephone cables. Thus, only a relatively few plug connections need be made without the necessity of removing the jack from the main frame. The housings for each jack panel are so contoured as to form a horizontally oriented recess, one for each jack panel, when a plurality of such jack panels are assembled on the main frame in stacked relation.

Abstract: An environmentally protected housing for receiving a connector block in which a multiplicity of central office protector modules can be mounted. The housing is designed such that its surface area is slightly larger than the surface area of the connector block and when the block and modules are mounted in the housing the top of the modules is just below the cover of the housing. Telephone cables which are used to connect to the cables from the central office and from the subscribers enter the housing and are wired to the rear of the connector block. The connector block is mounted in the housing and the modules are placed therein. A potting compound is then poured in the bottom of the housing to thereby environmentally seal the terminals and connections thereto on the rear of the protector block. The housing has a cover which has a suitable seal on its inside surface. The closing of the cover provides the environmentally protected housing.
