ELECTRICAL COMPONENTS AND BREADBOARD FOR ELECTRICAL CIRCUIT STUDY KIT

摘要

Provided are electrical components and a breadboard for an electronic circuit study kit. The breadboard includes: a base formed of a metallic material to a predetermined width so that an electronic circuit kit can be attached to the base by a magnetic force; an interconnection sheet which is disposed on an upper portion of the base and in which a plurality of power pads for electric short and a plurality of ground pads which are adjacent to one another on its upper surface, are formed to be spaced apart from one another from one side direction to the other side direction on a plane, the power pads and the ground pads are connected to power terminal pads and ground terminal pads which are formed in predetermined positions of an upper surface of the interconnection sheet, respectively, a plurality of interconnection pads are formed between one power pad and one ground pad which are adjacent to each other from another power pad and another ground pad which are adjacent to each other, to be spaced apart from one another in a predetermined pattern, the interconnection sheet being formed of one of a thin plate and a film sheet made of an insulating material; a circuit board which is disposed on an upper portion of the interconnection sheet and in which terminal holes are respectively formed in corresponding positions of the power terminal pads and the ground terminal pads of the interconnection sheet and a plurality of circuit connection holes are perforated by a predetermined distance so that the circuit connection holes can be located on vertical upper portions of the power pads, the ground pads and the interconnection pads of the interconnection sheet; an insulating plate disposed on a lower portion of the base and formed of an insulating material; and a combining means of the circuit board allowing the base to be combined with an upper portion of the insulating plate, the interconnection sheet to be combined with an upper portion of the base and the circuit board to be disposed and fixed on an upper portion of the interconnection sheet.
