<p>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.</p> |
