Abstract

The present invention refers to a plug connection for a mobile terminal. In order to provide an improved plug system which overcomes the problems of known solutions, according to the present invention, a plug connection is provided for electrically connecting a power supply unit which is to be supplied with mains voltage and is arranged within a mobile terminal via a power line carrying mains voltage or via a coupling piece, which can be coupled to a conventional power line to the mains voltage. The preferably flexible power line can be coupled to the power supply unit via a plug system comprising a plug connector and a receptacle, said plug system being dimensioned in a way, that it is smaller than plug systems according to IEC 320, and that it is complying with the valid standards in respect to the contact and handling safety.

Claims

1. A plug connection for electrically connecting a power supply unit within a mobile terminal and which is to be supplied with mains voltage via at least one of a power line carrying mains voltage or a coupling piece which can be coupled to a conventional power line to the mains voltage,

wherein the power line can be coupled to the power supply unit via a plug system comprising a plug connector having first and second channels, within which are located respective contacts, and a receptacle, said plug system being dimensioned to be smaller than plug systems according to IEC 320, said plug connector defining respective depths of the channels to the contacts, wherein the sum of the respective depths is greater than that of plug connectors according to IEC 320 to maintain compliance with rated values of contact and handling safety of plug systems according to IEC 320.

2. The plug connection according to claim 1, wherein the receptacle comprises a receptacle body and an end termination of at least one of a power line and a receptacle body of a coupling piece, wherein the receptacle comprises pin channels and has a length, and wherein the length of the receptacle and the depth of the pin channels to contacts within the receptacle are dimensioned in a manner in compliance with regulations for contact safety and electric strength.

3. The plug connection according to claim 2, wherein the plug connector has a plug funnel which corresponds to a length of the receptacle body.

4. The plug connection according to claim 1, wherein the plug connector is directly formed as a plug connector for an electric input to a battery system of the mobile terminal.

5. The plug connection according to claim 1, wherein the plug connector is coupled within the mobile terminal by a snap fit.

6. The plug connector according to claim 1, wherein the plug connector is coupled within the mobile terminal as a built-in connector plug for mounting on a circuit board.

7. The plug connection according to claim 1, wherein the receptacle is formed as a built-in receptacle.

8. The plug connection according to claim 1, wherein the receptacle is formed as a termination of a power line.

9. The plug connection according to claim 8, wherein the receptacle is provided with a strain relief integrated into an end termination of the power line.

10. The plug connection according to claim 1, wherein the coupling piece is provided for the connection between a receptacle according to IEC 320 and a receptacle of a plug system dimensioned to be smaller than plug systems according to IEC 320 and in compliance with standards in respect to contacts and handling safety.

11. The plug connection according to claim 10, wherein coupling piece is provided for the connection between a receptacle according to IEC 320 of the type C8 and a receptacle of a plug system dimensioned to be smaller than plug systems according to LEC 320 and in compliance with standards in respect to contacts and handling safety.

12. The plug connection according to claim 1, wherein the mobile terminal is a telephone.
