A method of manufacturing a shell element ( ) for an electronic device, said shell element ( ) having a front part( ) and at least one part that is angled in relation to said front part ( ). The shell element ( ) further comprises a formed sheet ( ) that constitutes at least a part of the outer surface of said front part ( ) and at least a part of said at least one part that is angled in relation to the front of the shell element ( ). The method comprises the steps of first forming a sheet ( ) to a desired shape including a part that is angled in relation to a front part ( ) and then injection molding a plastics material on the back of the formed sheet ( ). At least one opening ( ) is provided in the angled part of the formed sheet ( ) before the plastics material is injection molded on the back of the formed sheet ( ) and the at least one opening ( ) is left open during the injection molding of the plastics material on the back of the formed sheet ( ). A shell element manufactured by this method is also disclosed.

Method for manufacturing a shell element for an electronic device

The present invention relates to a device for connecting two electrical circuits (2,17;15,16) by a connection which permits that the two circuits easily can be separated and reunited again at the same time as interference and scratching noise in the connection mechanism are avoided. A first carrier (14, 28) is movable around a shaft (1), which is fastened onto a second carrier (7, 29). The first carrier (14, 28) can easily be removed from the shaft (1) and refitted again. The first carrier (14, 28) has a projecting part (8, 23, 30), which presses against an electrically conducting elastomer (4,18a-l, 21, 33) localized on the second carrier (7, 29). On the projecting part (8, 23, 30) there is an electrically conducting part (9, 20a-l, 24a-h), which is connected to a first electrical circuit (2,17) localized on the first carrier (14, 28). The electrically conducting elastomer (4,18a-l, 21, 33) is connected to a second electrical circuit (15,16) localized on the second carrier (7, 29). By means of co-operation between the projecting part (8, 23, 30) and the elastomer (4,18a-l, 21,33), an electrical connection between the first (2,17) and the second circuit (15,16) is achieved.
