And the connectors 30 and 35 are inserted and connected.

[0003]

[Problems to be Solved by the Invention] However, in electric / electronic devices using conventional FPC and PCB,
A connector connection portion 21 in which a terminal array portion 23 of an FPC (flexible printed wiring board) 22 is folded into a device case 20 and a connector connection portion 25 in which a tab 27 provided on a PCB (print circuit board) 26 is projected are individually provided. To increase the size of electrical and electronic equipment,
There is a problem that the connectors 30 and 35 to be individually inserted and connected to the connector connecting portions 21 and 25 are extremely uneconomical, and the connection work is complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a connection portion of electric / electronic equipment which is excellent in economy and workability, and in which a wire harness can be modularized.

[0005]

According to the present invention, a terminal arrangement portion of an FPC (flexible printed wiring board) is folded into a connector connection portion provided in an equipment case, and a tab arranged on a PCB (print circuit board) is inserted. A protruding electric / electronic device, and a connector in which a terminal fitting provided with a spring contact for press-contacting the terminal array portion of the FPC and a female terminal connected to a tab disposed on the PCB are housed in a terminal housing. A connection part of an electric / electronic device using an FPC and a PCB is configured to solve the conventional problems.

[0006]

[Function] In the connector connection part provided in the equipment case, FP
Terminal arrangement part of C (flexible printed wiring board) and P
By arranging the tabs arranged on the CB (print circuit board) collectively, the size of the device case can be reduced, and the number of connectors to be plugged into the connector connection portion can be reduced. Further, by combining the terminal arrangement of the FPC and the tab arrangement arranged on the PCB according to the use, modularization of the wire harness becomes possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded view of an essential part showing an embodiment of the present invention, and FIG. 2 is an explanatory view of an essential part showing a connection state. In FIG. In the connection portion, a PCB (to be described later) is provided on the bottom surface of the connector connection portion 2.
(Print circuit board) The insertion openings 3 through which the tabs 8 provided in the print circuit board 7 are inserted are arranged. Reference numeral 4 denotes an FPC (Flexible Printed Wiring Board), and a terminal arrangement portion 5 of the FPC 4 is disposed on an inner surface of the connector connection portion 2 provided in the device case 1. Reference numeral 6 denotes a protective cover put on the FPC 4. 7 is a PCB stored in the equipment case 1
(Print circuit board), 8 are tabs arranged on the PCB, and the tabs 8 are inserted through the insertion openings 3 arranged in the bottom surface of the connector connection portion 2 provided on the device case 1;
It protrudes into the connector connection part 2.

Reference numeral 10 denotes a connector. A terminal fitting 12 provided with a spring contact 13 for press-contacting the terminal arrangement portion 5 of the FPC (flexible printed wiring board) 4 in a terminal storage chamber 11 of the connector 10, and a PCB (printed). Female terminal 1 to be inserted and connected to tab 8 provided on circuit board 7
4 are stored. W is a wire harness connected to the terminal fitting 12 and the female terminal 14.

When the connector 10 is inserted and connected to the connector connection portion 2 provided on the equipment case 1, as shown in FIG. 2, the terminal arrangement room 5 of the FPC (flexible printed wiring board) 4 has the terminal storage chamber 11 of the connector 10. The spring contacts 13 of the terminal fittings 12 housed therein are pressed against
The female terminal 14 is inserted and connected to the tab 8 provided on the (print circuit board) 7, and the electrical / electronic device and the connector are electrically connected.

[0010]

According to the present invention, as described above, the terminal of the FPC (flexible printed wiring board) 4 can be formed by a very simple operation of inserting and connecting the connector 10 to the connector connecting portion 2 provided on the equipment case 1. A tab 8 provided on the arrangement portion 5 and a PCB (print circuit board) 7, and a terminal fitting 12 housed in a terminal housing 11 of the connector 10.
And the female terminal 14 can be connected collectively.
The workability is remarkably improved, and the number of connector connecting portions 2 provided on the device case 1 can be minimized, so that the device case 1 can be reduced in size. Target, and
The wiring harness W can be modularized by combining the terminal arrangement of the terminal arrangement part 5 of the FPC (flexible printed wiring board) 4 and the arrangement of the tabs 8 provided on the PCB (printed circuit board) 7 according to the application. And so on.
