Coupling structure for a flat wiring cable having non-uniform pitch

1. A coupling structure of a wiring member for coupling a plurality of connector terminals with the wiring member comprising:

the wiring member including a plurality of flat-type conductors arranged in parallel in a width direction of the wiring member and covered on an outer periphery of the flat-type conductors by an insulation member;

the plurality of connector terminals electrically coupled to the wiring member in an orthogonal manner so as to match to terminal pitches of a complementary connector,

wherein a first pitch of at least one flat-type conductor of the plurality of flat-type conductors is different from that of remaining flat-type conductors of the plurality of flat-type conductors and a second pitch of at least one connector terminal of the plurality of connector terminals is different from that of remaining connector terminals of the plurality of connector terminals.

2. The coupling structure of the wiring member according to claim 1 , wherein conductor pitches between the respective flat-type conductors of the wiring member are made different according to a circuit to be coupled.

3. The coupling structure of the wiring member according to claim 1 , wherein each of width sizes of the flat-type conductors and each of width sizes of the connector terminals coupled to the flat-type conductors is made differ according to a current capacity of a circuit to be coupled thereto.

4. The coupling structure of the wiring member according to claim 1 , wherein the second pitch is greater than the first pitch.

5. The coupling structure of the wiring member according to claim 1 , wherein each of the terminal is formed in a rectangular box shape in which upper surface is opened,

wherein each of the terminal blocks has a positioning frame part formed at a side wall and an erection wall provided on the positioning frame part; and

wherein the terminal blocks are stacked to each other by engaging the positioning frame parts with the erection walls to constitute a single laminated member.

6. The coupling structure of the wiring member according to claim 1 , wherein a terminal block is attached to the wiring member, and

the terminal block is configured that the connector terminals are disposed in parallel so as to cross with the flat-type conductors on a same plane and be conductively coupled to the predetermined flat-type conductors, respectively.

7. The coupling structure of the wiring member according to claim 6 , wherein the terminal block includes partition walls each of which partitions between adjacent ones of the connector terminals so as to protrude toward inside thereof.

8. The coupling structure of the wiring member according to claim 6 , further comprising a connector housing which is configured that when the terminal block is inserted therein, one ends of the connector terminals are protruded within a fitting space opened at a front surface thereof to be fitted with the complementary connector and the wiring member is derived from a side surface thereof.

9. The coupling structure of the wiring member according to claim 8 , wherein a plurality of the terminal blocks are laminated and housed within the connector housing.
