  • Patent number: 4964788
    Abstract: A hermetic terminal for carrying electric current into the housing of a hermetic compressor, including a metallic body member formed with three collar portions that define apertures through which respective fusible terminal pin assemblies extend. Each terminal pin assembly includes two electrically conducting pin segments interconnected by an electrically insulating sleeve member having opposite open ends into which respective ends of each pin segment are telescopingly received. The sleeve member and pin segments define a closed cavity in which a cylindrical fusible link is disposed. Opposite ends of the fusible link are received within respective counterbores in axial ends of the pin segments within the closed cavity, and are retained therein by a brazed joint. Each pin assembly is sealingly retained within a respective collar portion of the terminal body by a glass seal, which contacts the insulating sleeve and optionally surrounds one of the joints between the insulating sleeve and the pin segments.

  • Patent number: 4965413
    Abstract: The electric fence insulator of linear polyethylene plastic includes a body having a rear portion thereon for attaching the body to a fence post. Forwardly of the body is a clip unit having an upper latch mechanism. More specifically, the clip unit includes a first panel integrally attached to the body and a second panel resiliently connected at its lower end to the lower end of the first panel through the agency of a bight portion. The latch mechanism includes an upwardly directed keeper portion having an angled edge thereon, the angled edges being vertically overlapped with respect to each other so that a latching engagement can be effected by manipulating a tab with one's fingers, the tab projecting upwardly from the hook portion. When latched, the electric fence insulator securely holds a braided tape-type conductor, yet permitting the release of the conductor when the tab is again manipulated to unlatch the mechanism.
