Abstract
A card-receiving device for a communication apparatus, such as a handheld device or a personal computer card, receives a circuit card, such as a SIM-card. The device includes a body member having a card-receiving portion, a guide that allows movement of the body member to be performed in relation to a printed circuit board of the communication apparatus, and a switch for controlling an electric circuit interfacing and/or powering the circuit card. The switch includes a first contacting mechanism adapted to directly contact a second contacting mechanism of the printed circuit board for enabling the electric circuit.
Claims22
A card-receiving device for a communications apparatus, such as a handheld device or a personal computer card, and for receiving a circuit card, such as a SIM-card, including a body member displaceable relative to a printed circuit board of the communications apparatus and having a card-receiving portion and a guide means allowing substantially longitudinal movement of the body member to be performed in relation to the printed circuit board of said communication apparatus, and a switch for controlling an electric circuit interfacing and/or powering said circuit card including a pair of resilient contact members arranged on the body member for directly physically contacting a pair of contact surfaces formed as a part of a surface of said printed circuit board,
- wherein said electric circuit is enabled when there is direct contact between the pair of resilient contact members and the pair of printed circuit board contact surfaces.
A card-receiving device for a communications apparatus, comprising:
- a body member displaceable relative to a printed circuit board of the communications apparatus and having a card-receiving portion for receiving a circuit card and a guide for allowing movement of the body member in relation to the printed circuit board of the communication apparatus, and
- a switch mechanism providing an electrical interface between the printed circuit a board and a received circuit card and including a pair of resilient contact members arranged on the body member to directly physically contact a pair of contact surfaces formed as a part of a surface of the printed circuit board to permit transmission of electrical signals between the printed circuit board and the received circuit card,
- wherein an electric circuit for the transmission of electrical signals between the printed circuit board and the received circuit card is enabled when there is direct contact between the pair of resilient contact members and the pair of printed circuit board contact surfaces.
