Abstract: A phone jack connector is described with which a multiple conductor cable can be connected to the lead frame inside the phone jack using insulation displacement contacts (IDCs) but without the use of a special tool. A yoke assembly for receiving the cable aligns the individual conductors with IDC's located on a conductor assembly having a lead frame electrically connected to the IDC's. A screw thread is located on a wall on the conductor assembly and can be engaged by a cable nut that fits around the yoke assembly. When the nut is manually rotated it forces the yoke assembly against the IDC's and thereby causes an electrical contact to be made between the conductors and the lead frame of the phone jack.

Abstract: An insulation displacement connector is provided that has two housings. The first housing encloses surge protection. Terminals extend from the first housing. The second housing has insulation displacement terminals with first ends for connection with insulated wires and with second ends for connection to the terminals extending from the first housing. The two housings are to be joined together to complete an electrical line from one insulation displacement terminal to the other via the surge protection. Thus, surge protection is in one sub assembly protected from the environment, and the insulation displacement terminals are in another subassembly protected from the environment. The housings have a detent assembled condition enabling relative positional adjustment before joining of the housings. Electrical testing for the line circuit and for the surge protection may be performed upon the closed assembly.

Abstract: This invention discloses a network termination module which comprises a base structure having a means for grounding. Mounted on and above the base structure are a pair of insulation displacement terminals, a telephone jack and subscriber terminals. The insulation displacement terminals are electrically connected to the telephone jack. The network termination module also includes an openable cover which, in its closed position, establishes electrical connection between the insulation displacement terminals and the subscriber terminals, and, in its open position, breaks the electrical connection between the insulation displacement terminals and the subscriber terminals. The cover, in its closed position, also closes off access to the jack and to the subscriber terminals. Disposed within the base structure is a protector element which is electrically connected to the insulation displacement terminals. The protector element is also electrically connected to the means for grounding.

Abstract: A device (1) is described for disconnectably connecting cable wires to a contact plate (2). The contact plate contains a through opening (9) and, in use, one of the cable wires to be contacted is urged into contact with the edges of that opening (9). The cable wire is moved by a thrust piece (3) which also contains a through opening (24) and which is moved relative to the through opening (9) in the contact plate by means of a screw element.

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 telecommunications terminal (10) includes a series of teeth (14) opposite a juxtaposable surface (25). The region between the teeth (14) and surface (25) has a progressive taper such that a wire (22) captured therebetween is progressively engaged thereby.

Abstract: An insulation displacement terminal comprises a clamp having an internally threaded tubular portion to accommodate a screw. An insulated telephone wire can be inserted into an aperture in the clamp. When the screw is screwed all the way into the clamp, a cylindrical blunt edge thereon will displace the insulation on the wire and make contact with the metal core of the wire. There is a sealing material in the terminal to seal around the point of contact. A well and axial hole in the screw can accommodate sealing material that is displaced by the screw.

Abstract: This invention provides a terminal block or an adaptor where the binding posts and the caps which screw on the binding posts are adapted to receive small wires without breaking or cutting the wires when the cap is installed with normal installation torque for binding posts. The binding posts and cap can also receive large gauge wires and make connection therewith through the insulation on the wire without cutting or braking the conductor in the wire.

Abstract: An electrical connector is disclosed which makes connection to one or more unstripped insulated conductors. The connector includes a movable contact assembly disposed in a cavity for movement between open and closed positions. The connector includes a fixed contact electrically coupled to a contact of the movable contact assembly at least in the closed position of the movable contact assembly. The cavity is sealed except for one or more inlets through which one or more conductors are inserted into the cavity for connection. The cavity receives a water-proofing or sealing compound. The connector is constructed so that the cavity volume is constant in both the open and closed positions and during travel of the movable contact assembly. Thereby, compound is not forced out of the cavity when a conductor is connected or disconnected, i.e., when the movable contact assembly is moved. An activator for moving the movable contact assembly is insulated from the contacts of the connector at all times.
