  • Patent number: 4646101
    Abstract: An antenna support is provided by a molded plastic member comprising a block having a vertical passage therein, a horizontal guideway on the top of the block, and detent instrumentalities associated with such guideway. The support is designed for use with a 40 MHz wire rod antenna shaped by multiple "L" bends therein to have a middle section comprising two horizontal arms normal to each other and, at its extremities, two vertical arms normal to the middle section. The support is assembled with the antenna by passing one of the antenna's vertical arms through the vertical passage in the block, and by seating the horizontal antenna arm adjacent that vertical arm into the support guideway so that such horizontal arm is snap-fittably held in that guideway by such detent instrumentalities. Thereafter, the unit consisting of the antenna and its support is assembled with a printed wiring board so that the support maintains the antenna in a predetermined desired positioning thereof relative to the board.

  • Patent number: 3953103
    Abstract: A plug-in terminal for connecting a stranded insulated conductor with a conductive path on a circuit board includes a barrel of ductile metal for receiving a stripped end of the conductor. The barrel has a first section at a first end thereof for gripping the insulation on the conductor adjacent the stripped end, a second openended section at a second and opposite end thereof for surrounding and loosely gripping the strands at the extremity of the stripped end, and a third section, between the first and the second sections, for surrounding and tightly gripping the strands. After being crimped onto the conductor, the terminal is extended through a hole formed through the circuit board and the conductive path thereon. Locating and locking tabs extend from the terminal to position the terminal within the hole with the second section projecting beyond the conductive path, and to then secure the terminal within the hole.
