An aerial terminal has an increased density of connections and can be mounted alternatively on a pole or a cable. It has a housing with parallel side walls and end walls and a central wall extending across between the side walls, forming back and front chambers. A plurality of apertures extend in rows in the central wall and terminals are positioned in the apertures. The terminals are arranged in pairs, the front ends being in the front chamber and the back ends in the back chamber. Protector modules can be provided as part of a terminal for each pair. An openable cover and support brackets are also provided.

Aerial cable terminal

An interface for connection between incoming telephone lines and the customers equipment has a base for mounting on a support surface, with terminals for connection of incoming telephone lines and one or more plug-in positions for plug-in modules. Protectors are positioned in the modules. Each module has a modular jack. An intermediate cover fits over and is attached to the base, covering also the modules but with one or more apertures for access to the jack or jacks. The conductors from the customers equipment either terminate in modular plugs which insert directly into the jacks or terminate in spade terminals which are connected to terminals on the intermediate cover. In the latter case, a short interconnect cable connects at one end to these terminals and at the other end has a modular plug for insertion into a jack. An outer cover extends over the intermediate cover and the modular jack or jacks.

Telecommunications interface with protector modules

A connector for mounting on a vertical main frame has an elongate body portion containing a protector field and an elongate jumper field extending along one side. The connector is mounted on the frame member by a bracket which mounts the connector so that the body portion extends at an angle to the plane of the main frame. With an appropriate angle, a useful space is provided between connectors, for access, while removal and replacement of protector modules, and entire connectors, is readily available. One particularly appropriate angle is about 53.degree., while another is about 70.degree., although these can vary. A test field can also extend along one side, adjacent to the jumper field.

High density connector for main frames in telephone systems

A connector has a rectangular box-like form body with end walls and side walls and a transverse wall dividing the body into front and back parts. The transverse wall extends from one end wall to the other but at the sides extends backwards a distance from the side walls and then extends laterally to the back ends of the side walls. This forms a central web portion having a channel along each side and a back chamber between the channels. Terminals are positioned in the central web portion. A stub cable enters through an end wall into the back chamber, the cable conductors connected to rear ends of the terminals. Drop wire conductors can enter through grommets to connect to the front ends of the terminals. A cover is pivotally mounted at one end of the body. The back chamber is filled with potting compound after connection of the cable conductors to the rear ends of the terminals.

Pole mounting connector

An interface for use with telecommunications systems, at a customers premises, comprises a module for connection to the incoming telephone lines and having a modular jack for plugging in of the customers lines. Conveniently the module is a plug-in arrangement, and incorporates line protectors. Back-up protectors can also be provided. The module can also connect to, and also incorporate circuits for providing services such as automatic number identification and similar services.

Interface module with modular jack for telecommunications systems

A protector module, or assembly, for telephone lines and similar systems, has line terminals and a ground terminal in the base. The line circuit is between a related pair of line terminals. The line circuit includes part of a line bracket which extends up the side of the housing. The line bracket extends to the outer end of the housing and an aperture in the end of the housing permits access by a test probe to the line bracket. Normally, two line brackets are provided each associated with a pair of line terminals. A ground bracket also extends up the housing, being connected at one end to the ground terminal and having a flange at its other end. Between the outer end of the line bracket and the flange on the ground bracket a back-up or other form of protector member can be positioned.

Overload protector for communication systems

An aerial cable terminal has a one piece molded plastic housing with a dividing wall which divides the interior of the housing into front and back compartments. Terminals are mounted in the dividing wall, for example in hollow bosses extending into the front compartment. The conductors of a stub cable extend through the back compartment and are connected to the rear ends of the terminals. Drop wires enter at the bottom into the front compartment and are connected to the front ends of the terminals. A hinged cover closes the front compartment. Potting compound fills the back compartment. Two terminals can be assembled back-to-back, with conductors from one stub cable connected to both sets of terminals. Support hangers are provided on the top of the housing, one set of hangers for a single housing and another set which combines with hangers on the other housing to form combined hangers. Pivotal drop-wire support rings are provided at each end.
