A data card connector (43) is disclosed which comprises a housing defining an aperture for receiving a data card with contacts, electrical connectors (14) for engaging the data card contacts to couple the data card contacts to an electronic device, and a cover (12) moveable between an open position and a closed position. The data card connector further comprises an indicator (19,20) for indicating when the cover is in the closed position. When the cover is in this closed position, the contacts of the data card are connected to the electronic device and electric connection between the data card and the electronic device may be affects.

DETAILED DESCRIPTION According to the invention there is provided a data card connector comprising: a housing defining an aperture for receiving a data card; and electrical connectors for coupling a data card and a cover movable between an open position and a closed position, wherein the data card connector further comprises an indicator for indicating whether the cover is in the open position or in the closed position.
By this indicator it is secured that the contacts between the data card and the data card connector are closed before any data contact from other electronics, e.
g.
, electronics to read out the data card, is made to the data card before the cover is in the closed position.
Furthermore the power supply for the data card can for example be turned on after it is indicated that the cover is in the closed position.
Any damages to the data card because of unsecure electrical contact to the data card during the insertion of the data card is prohibited.
The indicator is preferably a switch.
The switch can for example be in the closed position when the cover is closed or in the opened position when the cover is open.
Preferably the switch comprises electrical contact elements in the cover and the aperture for receiving the data card.
When the cover is opened the contacts in the aperture and in the cover are not connected with each other and the switch is open.
After the cover is closed the contacts have contact with each other and the switch is closed and indicated the cover closed position.
The construction of the switch preferably comprises a contact plate at the inner surface which is directed towards the aperture and the aperture comprises two contact springs directed towards the cover and when the cover is in the closed position the contact plate connects the contact springs for indicating the cover closed position.
Further the indicator indicates the cover position to a control unit and the control unit establishes a data connection to the electrical connectors upon cover-closed indication
