Abstract: An electrical power distribution system is provided with an elongate track and a plurality of power tap assemblies that are engageable with the track. The power tap assemblies may be moved to any desired location along the track. Power may be fed into the track through one of the assemblies and taken out of the track through another of the assemblies. Receptacles may be mounted to one or more of the power tap assemblies. A latch system can hold the power tap assemblies in (1) a fully inserted, electrically engaging orientation and (2) an electrically disconnected orientation wherein the components are still supported on the track. The components employ spring terminals which establish electrical contact through a surface-to-surface butt engagement with a conducting member. Mechanical key systems are provided for preventing improper mounting of the components on the track and for preventing the connection of more than one power in-feed to the track.

The fastening piece also includes a rod connected to the body by a connection zone including a tooth. The blade spring has a longitudinal slot, a first bridge at one end of a curved part and a second bridge at an arched end of the blade spring; these bridges cooperate with the tooth and the third hook to fix the blade spring. The fastening piece is fixed to a case having an earthing terminal fixed to the rod on the fastening piece thereby providing an earth connection for the rail.

Abstract: The invention relates to a plug connector device for telecommunication and data systems, comprising a plug connector 1 and a connector bank 30. The connector bank 30 is formed of a housing with insulation displacement contacts 31 connected each to switching contacts 6. The plug connector 1 comprises a housing 2 with a connector tongue 4 supported therein and has contact tracks 5 on either side which can be inserted between two switching contacts 5 opposed to each other of the connector bank 30. The exterior distance B of two contact tracks 5 being smaller than the interior distance A between two stitching contacts 6.The plug connector 1 is provided such that there is no abrasion between the contact tracks 5 of the plug connector 1 and the switching contacts 5 of the connector bank 30 during the insert procedure. After the insert procedure, a contact connection with a sufficiently high contact force is established between the contact tracks 5 and the switching contacts 6.

Abstract: A connector apparatus or adaptor for use in a track-lighting system is provided which includes a grounding leaf to effect electrical contact between a grounded metallic track and a grounding conductor or grounding wire in the connector apparatus. The grounding leaf is slidably mounted onto the floor of the connector apparatus and provides an upwardly protruding lip which is placed in contact with an arm of the metallic track upon locking engagement therewith.

Abstract: High resistivity In-based compound Group III-V epitaxial layers are used to prevent substantial current flow through a region of a semiconductor device, such as a CSBH, DCPBH, EMBH or CMBH laser, a LED, a photodiode, a HBT, or a FET. Also disclosed is a hydride VPE process for making the high resistivity material doped with Fe. The Fe is supplied by a volatile halogenated Fe compound, and the extend of pyrolysis of the hydride is limited to allow transport of sufficient dopant to the growth area.

Abstract: An apparatus for connecting a high density cable assembly having a shield and to be connected to corresponding contact pins provided on a substrate having a grounding grid formed of conductive guides, each having a predetermined number of contact pins therein, including a connector to which the cable assembly is connected and which is to be mounted to the associated guide. The connector has a connector body, a connector cover surrounding the connector body, and a latching device provided between the connector cover and the connector body for easily latching and unlatching the connector to and from the associated guides.

Abstract: A frame connector assembly having a module field into which six pin alarm indicating modules can be inserted. The front face of the module field has six receptacles for each module, each receptacle associated with a respective one of the six module pins. The rear face of the module field has six pins for each module, each pin associated with a respective one of the six receptacles. The ground bus which interconnects all of the rear face ground pins of all of the modules in a given row follows a serpentine path. The module field receptacles are designed to make it difficult to insert a module with the pins reversed.

Abstract: A telephone distribution frame connector assembly for connecting incoming lines to inside equipment and comprises a module field block, a test field block and an equipment field block, and a frame member for mounting the field blocks to a telephone distribution frame. The field blocks are mounted to the frame member to define a generally rectilinear enclosure having one open side. An access panel is provided for normally covering the one open side of the connector assembly, and a panel securing arrangement is provided for removably, securely engaging a marginal peripheral portion of the access panel with a peripheral edge portion of the open side. One or more of the field blocks includes a plurality of ground terminals located interiorally of the enclosure thus defined. A common ground bus is electrically coupled to all of the ground terminals and an adjustable ground selection arrangement is provided for alternatively coupling the ground bus to one of a frame ground and an isolated ground.

Abstract: A connector is positioned at any selected location along an elongated electrical source in order to provide an electrical outlet where desired. The electrical source has a slot extending along its length, and a lengthwise extending electrical contact within the slot which is engaged by a connector contact on a contact member on the connector when the contact member is inserted in the slot. The contact member is shaped so that the connector contact is held in engagement against the lengthwise extending contact. The connector is a two-piece unit, with a contact unit including the contact member and a clamping unit which engages against the upper surface of the electrical source to hold the connector unit in a desired position. Bolts are provided to draw the clamping unit and the contact unit together to provide clamping at a desired position along the electrical source. The clamping unit includes outlets for providing electrical power to an appliance.

Abstract: An improved electric power distribution track comprises a metal-reinforced duct and at least three conductors extending along the length thereof. The duct is shaped to have a top wall, a pair of lateral sidewalls and a lengthwise bottom opening, and is composed of a correspondingly shaped metal-made core channel member covered by an insulation sheath of a plastic material. Three conductors are disposed on the inner sheath in a trigonous arrangement with one of the conductors on the top wall and the two others on the opposite sidewalls. Integrally projecting from the corresponding portions of the inner sheath are support members for holding the respective conductors at positions spaced inwardly from the inner periphery of the sheath. The support member on the top wall is connected to those on each of the sidewalls by a connection rib integrally extending therebetween for reinforcing the support members by one another to thereby retain the conductors held thereby in positions.
