BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle integrated electronic module, and more particularly, to a structure of an electronic module integrated with one connector per wire harness, comprising two printed circuit boards (PCBs), 2 By integrating the circuit connected to the I / O terminal of the printed circuit board and the circuit connected from the second printed circuit board to the I / O connector of the second printed circuit board, one multi-pole connector per wire harness is used. The present invention relates to a structure of an integrated electronic module for a vehicle configured to integrate a first printed circuit board and a second printed circuit board in one connector.

In general, the electric device of the car is a kind of nervous system, and only when the electric device is normally operated can the car exhibit excellent performance, and the electric device of the car is applied to the parts of the vehicle and other parts of the body other than the engine. The body is equipped with various electronic equipment.

In general, wiring through a junction box is configured to supply electricity to various electric appliances and motor driving devices of a vehicle, and the junction box is provided with overcurrent and overload such as fuel tanks, engines, air conditioners, equalizers, and warning indicators. A fuse, a relay, or the like is provided as a protection device to prevent the damage.

The junction box processes the wiring from the harness to the fuse or the relay terminal with a printed circuit board (PCB), and the wiring of the printed circuit board is electrically connected to the harness through a connector. These junction boxes provide wiring reliability while improving workability, and each one is mounted around the engine compartment and the driver's seat.

On the other hand, the indoor side of the vehicle is equipped with a number of small modules that are individually controlled to control the driver convenience of the vehicle, which is composed of one large module and one or two microcomputers are configured to control this electronic control module (electronic control module) It is called).

The electronic module includes basic functions for driver convenience of a vehicle, such as power window timer control, one touch power window, door lock control, and wiper control. Rear defog as an optional feature including room lamp decay, illumination control, chimebell, battery saver, rear defog control module, and more Rear fog control, shiftlock control, keyless entry, day time running light module, and the like.

In addition, the junction box and the electronic modules all perform a function of transmitting and distributing current, and it is common to configure an integrated system. Conventionally, the junction box and the electronic module are electrically connected to each other to form a package product. In this way, the circuits connected by mutual wires among the circuits of the electronic box and the circuits of the electronic modules can be integrated to achieve more efficient circuit design.

In other words, the junction box and the electronic module are manufactured separately, and the male and female terminals are mechanically fixed to face each product so as to enable mutual electrical connection, and the junction box and the electronic module are connected side by side to one body in the injection molding. By minimizing the product size according to the vehicle design while eliminating the redundancy of the electrical connection on both sides by externalization, or by integrating and connecting the boxed electronic module to the junction box equipped with male and female connection terminals for electrical connection. An integrated scheme is proposed to minimize the interference space of the component arrangement that occurs when the chapters are side by side.

An example of such a prior art is disclosed in Korean Laid-Open Patent Publication No. 2002-9545.

However, in each independent circuit of the junction box part and the electronic module part, each independent connector was applied, and the circuit configuration using the individual connector was connected to the outside.

This leads to a large number of connecting connectors. For example, when circuits are to be divided into two or three types of wire harnesses, the number of connectors is required to be "number of times x 2" times (e.g., two kinds of harnesses). Four connectors, three connectors and six connectors), the size of the product, and the complexity of the vehicle assembly to work with the connector have been raised.

Furthermore, even in a structure in which a junction box and an electronic module are integrated into one circuit component (for example, a circuit assembly such as a PCB), the circuits are inevitably divided into two or three kinds of harnesses. Since there are many circuits of 100 or more, there is a problem in that it is not possible to solve the demands of automobile manufacturers for the simplicity of the process and the cost reduction by reducing the number of connectors.

As a result of intensive efforts to solve the problems of the prior art, the present inventors have two printed circuit boards to configure the circuit of the junction box on the first printed circuit board, and the circuit of the electronic module on the second printed circuit board. After the configuration, connect it with the connecting pin, and make the external injection molded connector shape, but adopt the predetermined multi-pole connector configuration to have one connector per one harness. While reducing the size of the construction while minimizing the connection connector was confirmed that the effect of the process clarity and cost reduction and completed the present invention.

Accordingly, an object of the present invention is to provide an integrated electronic module having a circuit configuration that can be technically simplified and economically cost effective.

In particular, the object of the present invention is to focus on ways to minimize the number of connecting connectors in connection with the wire harness.
