1. An electrical system, comprising:
at least two magnetically-attracted conductive tracks, at least one electrical apparatus and at least one adapter, the at least one adapter cascading the at least two magnetically-attracted conductive tracks, wherein:
the magnetically-attracted conductive track comprises a main body portion extending along a length direction and having a flat shape, the main body portion comprises: an attraction wall, a mounting wall arranged opposite to the attraction wall, a pair of side walls connecting the attraction wall and the mounting wall, and a pair of partition walls parallel to the side walls and located between the side walls; the side walls and the partition walls, together with the attraction wall and the mounting wall, form conductive grooves extending in the length direction and located at both sides, and form an accommodating space located between the conductive grooves; a slot is formed in a direction from the attraction wall towards the mounting wall and is in communication with the conductive grooves;
a pair of insulating portions, each accommodated in the conductive groove and provided with an accommodating portion in communication with the slot of the attraction wall;
a pair of conductive portions, each accommodated in the accommodating portion of the insulating portion; and
a magnetic element, accommodated in the accommodating space and attached to the attraction wall; wherein,
the insulating portion is attached inside the conductive groove; and the accommodating portion of the insulating portion comprises: a first space for accommodating the conductive portion, and a second space which is in communication with the first space and is smaller than the first space, allowing a conductor of a lamp to enter the first space from the second space to be electrically connected with the conductive portion;
the electrical apparatus comprises: a main body formed by extending along a longitudinal direction, an electrical connection module collocated with the main body, and a magnet module;
the electrical connection module comprises: a housing body formed by extending along the longitudinal direction, an elastic conductive terminal accommodated in the housing body, and a collocating portion provided on a surface of the housing body that faces the magnetically-attracted conductive track and extending in the longitudinal direction; the elastic conductive terminal and the collocating portion are arranged longitudinally in a row; and the elastic conductive terminal extends beyond the collocating portion along a height direction;
the elastic conductive terminal and the collocating portion are jointly collocated into the magnetically-attracted conductive track;
the elastic conductive terminal of the electrical apparatus and the collocating portion are jointly collocated into the second space of the magnetically-attracted conductive track; and the elastic conductive terminal further extends into the first space and is elastically abutted against a surface of the conductive portion to form an electrical connection;
the adapter comprises: an insulating body, and a conductive terminal arranged in the insulating body and partially protruding and extending out of the insulating body; the conductive terminal has a flat sheet shape and comprises: a base portion provided in the insulating body, and a docking portion protruding and extending out of the insulating body; the insulating body protrudes and extends at the docking portion adjacent to the conductive terminal to form a guiding portion spaced apart from the conductive terminal, and the insulating body is configured such that the guiding portion and the docking portion are jointly assembled into the at least two electrical apparatuses to achieve an electrical connection of the two electrical apparatuses.
