Abstract

In a function circuit incorporating type wiring device for an automobile, including a junction block employed for an electronic wiring in the automobile, and an electronic unit pack detachably connected to the junction block, the electronic unit pack being provided with a case, a printed board incorporated in the case and forming a function circuit for effecting connection of a signal between wire harnesses, a junction block connector formed on an outer periphery of the case and an external connector formed on the outer periphery of the case; the improvement comprises at least one tabular connection terminals led from the junction block into the junction block connector of the electronic unit pack and projected into the external connector of the electronic unit pack to form a through circuit, said tubular connection terminals being connected with a part of the function circuit on the printed board as required.

Claims

1. In a function circuit incorporating type wiring device for an automobile, including a junction block employed for an electric wiring in the automobile, and an electronic unit pack detachably connected to said junction block, said electronic unit pack being provided with a case, a printed board incorporated in said case and forming a function circuit for effecting connection of a signal between wire harnesses, a junction block connector formed on an outer periphery of said case, and an external connector formed on the outer periphery of said case;

the improvement comprising at least one tabular connection terminal led from said junction block into said junction block connector of said electronic unit pack and projected into said external connector of said electronic unit pack to form a through circuit, said tabular connection terminals being connected with a part of said function circuit on said printed board as required.

2. The function circuit incorporating type wiring device as defined in claim 1, further comprising a female terminal member electrically connected to said printed board by soldering.

3. The function circuit incorporating type wiring device as defined in claim 2, wherein said female terminal member comprises a base, a pair of vertical side walls formed on both sides of said base and bent back toward said base at its free ends, a receiving space defined between said base and said side walls for receiving said tabular connection terminal to provide electrical connection with said tabular connection terminal, an elastic contact portion extending from one end of said base into said receiving space, and a connection pin extending from the other end of said base and adapted to be connected to said printed board.

4. The function circuit incorporating type wiring device as defined in claim 1, further comprising a flexible printed board electrically connected to said printed board at one end and also electrically connected to said tabular connection terminal at the other end.

5. The function circuit incorporating type wiring device as defined in claim 4, further comprising a pin for fixing said flexible printed board to a projected portion of a housing for receiving said external connector.

6. The function circuit incorporating type wiring device as defined in claim 5, wherein said tabular connection terminal is formed with a resilient contact portion to be electrically connected with said flexible printed board.

7. The function circuit incorporating type wiring device as defined in claim 6, further comprising an elastic member attached to said projected portion of said housing for securing contact between said resilient contact portion and said flexible printed board.

8. In a function circuit incorporating type wiring device for an automobile, including a junction block employed for an electric wiring in the automobile, and an electronic unit pack detachably connected to said junction block, said electronic unit pack being provided with a case, a printed board incorporated in said case and forming a function circuit for effecting connection of a signal between wire harnesses, a junction block connector formed on an outer periphery of said case, and an external connector formed on the outer periphery of said case;

the improvement comprising at least one junction terminals fixed to said printed board and formed with a male terminal portion at one end and with a female terminal portion at the other end, said male terminal portion being projected into said external connector of said electronic unit pack, and a tabular connection terminal led from said junction block into said junction block connector of said electronic unit pack and inserted into said female terminal portion of said junction terminal to form a through circuit by the combination of said junction terminal and said tabular connection terminal, said junction terminal being connected with a part of said function circuit on said printed board as required.

9. The function circuit incorporating type wiring device as defined in claim 8, wherein said junction terminal comprises a base, a pair of vertical side walls formed on both sides of said base, a pair of elastic holding arms bent back from said side walls toward said base, a female terminal portion formed between said arms and said base for receiving said tabular connection terminal to provide electrical connection with said tabular connection terminal, a male terminal portion extending from one end of said base and adapted to be connected with said external connector, and a connection pin projecting from the other end of said base and adapted to be connected to said printed board.

10. The function circuit incorporating type wiring device as defined in claim 8, wherein said junction terminal comprises a base, a pair of vertical side walls formed on both sides of said base, a male terminal portion extending from one end of said base and folded inwardly at both sides thereof, and a female terminal portion comprising a pair of bent portions bent back from said side walls toward said base, a receiving space defined between said base and said bent portions for receiving said tabular connection terminal to provide electrical connection with said terminal, and an elastic contact portion extending from the other end of said base into said receiving space.

11. The function circuit incorporating type wiring device as defined in claim 10, wherein said male terminal portion is soldered at its base to said printed board.

12. The function circuit incorporating type wiring device as defined in claim 10, further comprising a second female terminal portion having a length smaller than that of said female terminal portion, said second female terminal portion comprising a pair of second bent portions bent back from said side walls toward said base, a second receiving space defined between said base and said second bent portions, and a second elastic contact portion projected from said base by partially cutting said base.

13. The function circuit incroporating type wiring device as defined in claim 12, further comprising a crank-shaped conductive member connected with said printed board at one end, and inserted into said second receiving space of said second female terminal portion at the other end.
