Arrangement for securing the SIM card in a mobile telephone

Claim 1

An arrangement for securing a SIM card (6) in a mobile telephone, the arrangement comprising a mobile telephone casing frame (1) with guiding means (2) for inserting said SIM card into said mobile telephone casing frame (1) and a SIM connector (4) with connector lugs (5) for making contact with said SIM card (6) after the insertion of said SIM card (6) into said mobile telephone casing frame (1) using said guiding means (2), characterized in that said mobile telephone also comprises a protrusion (8) as a part of said mobile telephone casing frame (1), and the relative position of said guiding means (2), said protrusion (8) and said connector lugs (5) is arranged such that when said SIM card (6) is inserted into said mobile telephone casing frame (1) using said guiding means (2) a force is applied to said SIM card to cause a flexible deformation in the shape of said SIM card (6) such that said SIM card (6) is enabled to slide over said protrusion (8), and when said SIM card (6) is fully inserted into said mobile telephone casing frame (1) and a pressing force (F) is introduced to urge said SIM card (6) toward said connector lugs (5), said SIM card takes a position in which said protrusion hinders said SIM card (6) from moving along said guiding means (2).

Claim 9

A method for inserting and retaining an electronic card in a radiotelephone, comprising the steps of: sliding the electronic card through an opening in a case of the radiotelephone, the step of sliding passing the electronic card over a protrusion disposed within the opening until the electronic card is fully inserted into an operating position behind the protrusion; electrically coupling the fully inserted electronic card to a plurality of electrical contacts, the contacts exerting a first force on a first surface of the electronic card for bowing the electronic card by an amount sufficient to enable the electronic card to be withdrawn from the enclosure by passing the electronic card back over the protrusion and back through the opening; and retaining the electronic card in the operating position by exerting a second force on a second surface of the electronic card that is opposite the first surface, the second force being sufficient to counteract at least a portion of the first force so that the amount of bowing is reduced to an extent that the electronic card cannot be passed over the protrusion.

Claim 10

A method for inserting and retaining an electronic card in a radiotelephone, comprising the steps of: sliding the electronic card through an opening in a case of the radiotelephone, the step of sliding passing the electronic card over a protrusion disposed within the opening until the electronic card is fully inserted into an operating position behind the protrusion; electrically coupling the fully inserted electronic card to a plurality of electrical contacts, the contacts exerting a first force on a first surface of the electronic card for bowing the electronic card by an amount sufficient to enable the electronic card to be withdrawn from the enclosure by passing the electronic card back over the protrusion and back through the opening; and retaining the electronic card in the operating position by exerting a second force on a second surface of the electronic card that is opposite the first surface, the second force being sufficient to counteract at least a portion of the first force so that the amount of bowing is reduced to an extent that the electronic card cannot be passed over the protrusion.
