The invention discloses a shell assembly and electronic equipment, the shell assembly comprises a key and a shell, the shell is provided with a key hole, the key comprises a conductive key cap, a clamping plate, a conductive elastic piece and a conductive key column, the conductive key cap is matched with the key hole and partially exposed out of the key hole, the clamping plate is buckled to the part, located in the key hole, of the conductive key cap, and the conductive elastic piece is arranged on the conductive key column. The end portion of the clamping plate is provided with a limiting clamping hook, the limiting clamping hook is matched with the limiting protrusion, and the conductive elastic piece is connected with the clamping plate and the conductive key column so that the conductive key cap and the conductive key column can be conducted, and the conductive key cap can move relative to the conductive key column. The conductive key column is conducted with the conductive key cap to meet the effective conductive requirement, and the conductive elastic piece can enable the conductive key cap to move relative to the conductive key column, so that the conductive key cap is effectively prevented from tilting and being stuck, the key is effectively pressed, and the effectiveness of the key is further improved.
