By adopting technique scheme, butt piece is bolt, the internal thread that bolt can arrange by through hole is screwed in through hole fixing, fixed effect is reliable, prevents bolt falling, and the end face of bolt is the end face of the screw portion of bolt, this face is for being placed in through hole, elastic component is connected between this end face and silver-plated, and bolt fixed effect is firm, and therefore elastic component contacts at both and directly can provide more stable support force for silver-plated.The cross section size of the head of bolt is set to be less than or equal to the cross section size of riveting column, mainly based on the fixing consideration of convenient riveted joint, when bolt is screwed in through hole, avoid the head of bolt radially to extend the end face of riveting column, the installation of silver contact is impacted.
The utility model is further set to: described elastic component is Compress Spring, and the end face of a described silver-plated and bolt side is in opposite directions equipped with the projection for inlay card Compress Spring.
By adopting technique scheme, elastic component is Compress Spring, between the end face of silver-plated and bolt, be for fixing Compress Spring, be equipped with projection in the end face of a silver-plated and bolt side in opposite directions, Compress Spring can be placed in projection, Compress Spring can effectively be fixed, can not be offset, make Compress Spring more stable to the supporting role of silver-plated.
The utility model is further set to: described riveting column is provided with flange in a side at silver-plated place.
By adopting technique scheme, in the time silver contact being mounted on conductive contact plate, flange can be fitted and the edge of conductive contact plate installing hole, for silver contact provides more effective fixing.
