Abstract

Abstract Described is an arrangement for removing electric charges which may be present or generated when terminals (9) of an elec­tronical apparatus, for instance a memory card, are connected to terminals (3) of a con­nector of an electric device. On both parts, the electroni­cal apparatus and the connector, electrically con­ductive contacting members (1, 5a) are provided which are brought into contact with each other when the apparatus is inserted into the connector before said ter­minals of the electronical apparatus come into contact with the terminals of the connector. By the contact between the contacting members any charges of the apparatus are discharged to ground before they can affect the electronic circuitry.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 72 words
An arrangement for removing electric charges which may be present or generated when terminals (9) of an elec­tronical apparatus are connected to terminals (3) of a con­nector of an electric device, comprising electrically con­ductive contacting members (1, 5a) on both, the electroni­cal apparatus and the connector, said contacting members being brought into contact with each other before said ter­minals of the electronical apparatus come into contact with the terminals of the connector.
Claim 2
Dependent Claim 72 words
An arrangement for removing electric charges which may be present or generated when terminals (9) of an elec­tronical apparatus are connected to terminals (3) of a con­nector of an electric device, comprising electrically con­ductive contacting members (1, 5a) on both, the electroni­cal apparatus and the connector, said contacting members being brought into contact with each other before said ter­minals of the electronical apparatus come into contact with the terminals of the connector.
Claim 3
Dependent Claim 56 words
An arrangement according to claim 1, wherein the electronical apparatus has a shutter (5) movable between a first position where it covers the terminals (9) of the electronical apparatus, and a second position exposing said terminals (9), and wherein said contacting members (5a) of said electronical apparatus are part of or connected to the shutter (5).
Claim 4
Dependent Claim 51 words
An arrangement according to any of claims 1 or 2, wherein said electronical apparatus includes a circuit board carrying said terminals (9) and an electronic cir­cuitry, said circuit board (8) being at least partly sand­wiched by metal panels (6) which are electrically connected to each other and to the shutter (5).
