Abstract: A method for connecting or terminating wires to a printed circuit is disclosed. The method includes applying layers, such as a first layer and a second layer, to the printed circuit. The first layer is applied over several active components on the printed circuit, and provides a sealant against ingress of contaminants in the active components. The second layer is a rigid layer applied over the first layer. When the printed circuit is placed in a fixture, a metallic element, such as a thermode or hot bar, presses against the wires to hold the wires against several terminals on the printed circuit. The metallic element is heated to melt solder between the wires and the terminals. The second layer is configured to resist compressive forces from the metallic element and the fixture, such that the printed circuit and the active components are not damaged during the connection process.

Abstract: A cable antenna includes a circuit board to which first ends of two antenna cables and a coupling cable are soldered. A second end of the coupling cable forms a connector for connection with a signal receiving/transmitting circuit. Each of the antenna cables has a second free end exposed to the atmosphere for receiving/transmitting electromagnetic signals. An outer jacket of each antenna cable is removed along a first predetermined length measured from the free end thereof to expose a braided shield. A second predetermined length of the braided shield measured from the free end is removed for exposing an inner dielectric layer that surrounds a core conductor. The second length is less than the first length thereby leaving a portion of the exposed braided shield on the inner dielectric layer. The braided shield that is cut from the cable is twisted to form an elongate consolidated conductor.

Abstract: An electrical connector (1/1A) for either through hole mounting or surface mounting comprises a common dielectric housing (10), a plurality of terminals (12) retained therein, and a pair of securing devices (20 or 120) mutually exclusively fixed in the housing.
