  • Patent number: 8246375
    Abstract: An electrical connector for connecting the bare end of a horizontal conductor with a horizontal printed circuit board, including a sectional housing having a base member seated on the printed circuit board. The base member contains an open-topped chamber and includes a vertical front wall the upper edge of which contains a vertical slot communicating with the chamber. A cover member is normally seated on the base member to close the chamber and the upper end of the slot. A lower electrically conductive cage member is arranged in the bottom of the chamber for electrical connection with the printed circuit board. The cover member is removable from the base member to open the tops of the chamber and the slot, thereby to permit the horizontal conductor bare end to be displaced laterally vertically downwardly into the slot and housing chamber toward electrical engagement with the lower cage member.

  • Patent number: 7367832
    Abstract: An adapter assembly for connecting a multi-contact electrical plug within a cable support arrangement includes an elongated adapter body containing a through passage and having a rectangular first end portion containing a chamber for receiving the electrical plug, and a tubular second end portion threadably connected adjacent its free extremity with a concentrically arranged cable sleeve, an annular sealing device being provided for sealing one end of the annular space defined between the cylindrical outer surface of the adapter body tubular end portion and the inner surface of the adjacent end portion of the concentrically arranged sleeve. A second annular seal is supported within the cable sleeve for sealing the entrance of the cable into the adapter through passage, and a third sealing ring is provided for sealing the space between the outer surface of the adapter body rectangular end portion and a slidably mounted outer sleeve member.
