A multiple cable electrical connector comprises a metallic body having a base portion and at least three spaced-apart legs extending upwardly from the base portion. The legs have axial recesses therein for receiving the ends of electrical conductor cables. Each leg has a lateral threaded bore intersecting the recess at substantially right angles and a setscrew is threadedly received in each bore. Each setscrew has an inner end received in the recess and a saddle clamp is mounted on the inner end of each setscrew in each recess. The base portion of the connector and at least one leg may be completely encapsulated in elastomeric electrical insulating material. The insulating material may be bonded to the base portion and unbonded to the one leg so that it is easily peeled off from the leg. The legs are spaced in such a manner that two connectors may be interdigitated to provide double the number of available recesses while taking up very little additional space.
A unitary power distribution block particularly suitable for high amperage application is disclosed. This new power distribution block features an electrical contact member in the form of a copper bus bar having distinct conductor engagement surfaces disposed in different horizontal planes. The bus bar is held within a steel skeleton to form an internal assembly and a shell of nonconductive material is molded around the internal assembly. The shell has a number of distinct conductor receiving cavities disposed on different horizontal planes of the distribution block.
A set screw bus connector comprising a bus with a secondary outlet and a service outlet extending from the bus. The service outlet comprises a terminal having a first borehole extending from its distal end to the bus, a first set screw in the terminal for securing a service cable in the first borehole, a second smaller borehole extending from the distal end of the terminal substantially parallel to but displaced from the first borehole, with the second borehole terminating short of the first set screw, and a second set screw in the terminal for securing a streetlight cable within the second borehole.
An electrical connector configured to maintain an electrical connection with a conductor during heating and cooling cycles is provided. The electrical connector includes a base portion and an arm extending from the base portion. The arm and the base portion combine to define an opening configured to receive the conductor, and one of the arm and the base portion defines a bore communicating with the opening. A fastener inserted into the bore is configured to retain the conductor inserted into the opening, and the arm is configured to deflect to provide a spring force that secures the fastener against the conductor during the heating and cooling cycles.
A terminal block assembly includes a housing having a base portion and partition walls extending from the base portion. The partition walls are spaced apart to define a cavity therebetween. The terminal block assembly further includes a terminal connector removably secured in the cavity between the partition walls. The terminal is configured to accept at least one of a bare wire and a contact attached to a wire. At least one of the partition walls includes a latch arm deflectable outward away from the cavity. The latch arm snappably retains the terminal connector within the cavity.
