Abstract

Provided is a circuit structure using a printed-circuit board with a novel structure that can provide a plurality of types of circuit specifications by switching connection of circuit patterns, allows circuit specifications to be easily identified, and achieves excellent connection workability and connection stability for circuit patterns. The circuit structure includes: a printed-circuit board 18 on which a plurality of circuit patterns are provided; and a circuit switching component, wherein the circuit switching component includes bus bar support bases on which any connection bus bars selected can be mounted and held, the plurality of types of connection bus bars are classified according to the number and the position of lead portions to be electrically connected to connection points, and a plurality of types of circuit specifications are provided by changing a mounting mode of the connection bus bars to the bus bar support bases.

First claim

What is claimed is:

1. A circuit structure comprising:
a printed-circuit board on which a plurality of circuit patterns are provided; and
a circuit switching component placed on the printed-circuit board, wherein
the circuit switching component includes a plurality of types of connection bus bars, and a bus bar support base on which any connection bus bar selected from the plurality of types of connection bus bars can be mounted and held,
respective connection points of the plurality of circuit patterns are disposed below the bus bar support base and arranged so as to be spaced apart from each other in an extension direction of the bus bar support base,
the plurality of types of connection bus bars are different from each other and are configured to engage different connection points of the plurality of circuit patterns so as to be electrically connected to the connection points, and wherein mounting any one of the plurality of connection bus bars to corresponding connection points of the plurality of circuit patterns provides a corresponding one of a
a plurality of types of circuit specifications.

2. The circuit structure according to claim 1 , wherein the plurality of circuit patterns include three or more circuit patterns, the connection points of the circuit patterns are provided below the bus bar support base, and three or more lead portion insertion holes are formed so as to extend through the bus bar support base at positions corresponding to the connection points of the three or more circuit patterns.

3. The circuit structure according to claim 1 , wherein the bus bar support base is formed integrally with an electric component mounted on the printed-circuit board.

4. The circuit structure according to claim 3 , wherein the electric component is a power supply connector module.

5. The circuit structure according to claim 2 , wherein the bus bar support base is formed integrally with an electric component mounted on the printed-circuit board.
