PCT No. PCT/SE95/00640 Sec. 371 Date Dec. 5, 1996 Sec. 102(e) Date Dec. 5, 1996 PCT Filed Jun. 2, 1995 PCT Pub. No. WO95/35017 PCT Pub. Date Dec. 21, 1995The invention relates to an electrical connector (15) comprising a cable connection part (15a) and a circuit-board connection part (15b), wherein the metallic casings (16, 17) of the connection parts are electromagnetically screening and earth potential connected and include means (such as 20) for providing the casings (16, 17) of respective connecting parts (15a, 15b) with a common earth potential (5') when the parts are in a mutually coacting state. The circuit board (4) includes edge-oriented, and resilient electrical contact means (30) connected to earth potential and coacting with the metallic casing of the circuit-board connecting part. A unit provided with electrical contact devices and positioned within the electrical contact means (30) is connected by its associated connecting device or devices with a circuit-board contact surface or surfaces through the medium of connecting wires or connecting pins. The metallic casing (16) of the circuit-board connecting part is comprised of four wall-parts (16a, 16b, 16c, 16d) which are normally, but not necessarily, angled at 90 DEG and of which three wall-parts (16a, 16b, 16c) define an opening (35) which faces towards the circuit board (4) and of which three wall-parts (16b, 16c, 16d) define an opening (36) which faces towards the cable connecting part. A circuit-board layer which is at least partially surrounded by the electrical contact means is connected to earth potential. This layer being located closely adjacent the electrical contact means (30). The electrical contact means (30) is comprised of spring contact strips surface mounted on the circuit board and with which the casing edge surfaces coact in a readily fitted and readily released fashion. |
