insulating members, where the insulating members are provided between the steel wires and the metal connecting sheets and located at the intersections, and fixedly connected with the steel wires and the metal connecting sheets;
connecting terminals, where both ends of each of the steel wires each are connected with one connecting terminal, and both ends of each of the metal connecting sheets are connected with two different connecting terminals; and
