Abstract
It is shown an electric connector for enabling galvanic contact between a contact pad of a first electric device and a contact pad of a second electric device. The connector is mechanically attachable to and detachable from at least the first electric device and comprises a first resilient contact pin connected to a second resilient contact pin. When mechanically attached to at least the first electric device, the first resilient contact pin is in abutment with the contact pad of the first electric device and the second resilient contact pin is in abutment with the contact pad of the second electric device.
Claims28
A mobile telephone terminal comprising:
- a housing;
- a flip-lid being attachable and detachable from said housing;
- and
- an electrical connector located within a hinge structure interconnecting the housing and the flip-lid including a first resilient contact and a second resilient contact, said first resilient contact being in abutment with a contact pad of said flip-lid and said second resilient contact being in abutment with a contact pad of said housing, wherein said first resilient contact and said second resilient contact maintain contact with said contact pad of said flip-lid and said contact pad of said housing, respectively, without being fixedly attached to said contact pads, wherein said electrical connector forms a part of the hinge structure separate from the housing and the flip-lid that enables a rotating motion between said housing and said flip-lid, wherein during the rotating motion said electrical connector maintains a continuous galvanic contact between said housing and said flip-lid.
