An electrically-conducting assembly for conducting a first housing and a second housing of an electronic device. The first housing is detachably combined with the second housing. The electrically-conducting assembly includes a retaining wall and a lapping part. The retaining wall is perpendicularly provided at the first housing, and a surface of the retaining wall has an electrically-conducting layer. The lapping part is perpendicularly provided at the second housing, and a surface of the lapping part has another electrically-conducting layer. The lapping part and the retaining wall contact with each other when the first housing and the second housing are combined so that the electrically-conducting layer and the another electrically-conducting layer are mutually conductive.
