摘要:
A device (3) for providing a mechanical and electrical connection between a radio frequency filter (RF filter) (1), with a radio frequency contact pin (11), and a printed circuit board (PCB) (2) is disclosed, where the contact pin (11) is adapted to be inserted through a pre-made hole (21) in the PCB (2) and where the device (3) is adapted prevent the contact pin (11) from leaving the PCB hole (21), thereby providing the mechanical and electrical connection. The device (3) is made out of a piece of sheet material (31), which has an opening (32) with a number of radial cut-outs (33a,33b,...,33n) forming a number of contact tabs (34a,34b,...,34n). The device (3) is adapted to be forced over the contact pin (11). The diameter (32a) of the opening (32) is smaller than the diameter of the contact pin (11) so that a radial contact force is created as the tabs (34a,34b,...,34n) are pressed back by the pin (11) when the device (3) is made out of an electrically conductible material (36), adapted to provided the electrical connection between the contact pin (11) and the PCB (2). The opening (32) is given a diameter in relation to the diameter of the contact pin (11) that will provide a contact force sufficiently strong to create a sufficient contact force and provide the mechanical connection.

Apparatus and methodology are disclosed for providing effective transmission of data to and/or from an electricity meter by providing embedded radio frequency components. An antenna and stripline or microline filter arrangement are provided as embedded components in association with a transmitter or transceiver portion of the electricity meter's metrology circuitry so as to provide control of out of band harmonic radiation and to provide enhanced signal transmission to and/or from the electricity meter, to accomplish automated meter reading communications or similar. The antenna element is configured and mounted such that, once the electricity meter is fully assembled, the meter case itself can be used as part of a radiating element. An overall resulting integrated design can achieve greater economy utilizing printed circuit board approaches with no additional parts, and with less uncontrolled surface radiation because of the otherwise buried or embedded structure.
