Description

IC circuit box for vehicle {Intergrated circuit module relay box for vehicle}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay box for a vehicle, and more particularly, by mounting a twin relay composed of an integrated circuit module (ICM) on a printed circuit board (PCB), while excellent in stability of operation. It relates to a vehicle ICM relay box for assembly is greatly improved.

In general, a vehicle is provided with various electrical devices necessary for driving such as a signal, and these electrical appliances are electrically connected to a battery to receive power for operation. Accordingly, the electrical equipment is operated by a relay which opens or closes an electrical circuit of each electrical equipment by operating according to an input signal (operation and stop, etc.) from an operation switch provided in the driver's seat.

The relay is configured to control one classification group per relay by classifying into several groups according to the operation characteristics of the electrical equipment, etc. Accordingly, the vehicle is usually provided with four relays. These relays are usually housed together in a fuse box and mounted in the engine room of the vehicle.

On the other hand, in recent years, the number of circuits in the vehicle is greatly increased due to the increase in the number of electronic devices due to the trend of electronic equipment as well as equipped with a lot of convenience devices, which is inevitably accompanied by complicated wiring of many wiring harness (wiring harness) none.

However, the conventional relay has a large size as a so-called linear relay, and it is difficult to set the mounting position in the vehicle because the relays must be fixed individually, and excessive assembly work is required. In addition, since the relays are simple circuits, the wiring is greatly increased. As a result, the conventional relay structure causes considerable difficulty in designing and routing the wiring path of the electronics.

SUMMARY OF THE INVENTION The present invention has been invented in view of the above-described conventional problems, and secures the design and space of wiring paths for electronic devices by integrating the relay-related circuits located in the main part of the vehicle at an optimal position on the circuit and the path to integrate the wire harness. And to provide an ICM relay box of a vehicle that can greatly improve the installation work is its purpose.

In order to achieve the above object, the IC relay box of a vehicle according to the present invention includes a lower cover fixed to a vehicle body; A relay module comprising a printed circuit board, a plurality of integrated circuit twin relays and input / output terminals mounted on the printed circuit board, and mounted in a lower cover; And an upper cover having a connection port coupled to the lower cover to shield the relay module, and having input / output terminals of the relay module exposed to couple the connector of the wire harness.

Accordingly, the present invention enables not only the relay-related circuits of the vehicle to be integrated at the optimum position on the circuit path, but also to integrate the wire harnesses of complex wiring into one connector, thereby greatly improving the wiring path design, space securing, and installation of electronic components. This makes it possible to reduce the number of circuits, improve assembly and reliability of vehicle electronics.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the vehicle IC relay box according to the present invention.

1 and 2, the ICM relay box for a vehicle according to the present invention, the lower cover 10 is fixed to the vehicle body (S), the relay module 30 mounted in the lower cover 10, and the lower cover ( 10 is assembled with the upper cover 30 to shield the relay module 20.

The lower cover 10 has a plurality of lugs 11 on two main surfaces for fastening them to the vehicle body S with screws 16. The lower cover 10 has a grid-shaped rib 12 in which the relay module 20 is seated therein for stable support in which the relay module 20 can withstand the vibration of the vehicle body, and at the same time, the relay module ( The printed circuit board 21 of FIG. 20 has a plurality of poles 13 which pass through the four corners thereof. And, on both sides of the other two main surfaces of the lower cover 10 a plurality of hooks for fixing the upper cover 30 by the elastically fitted to the corresponding pockets (pocket :) of the upper cover 30 to be described later ( hooks 14 are provided.

The relay module 20 has two integrated circuit twin relays 22 mounted on a printed circuit board 21 having a predetermined circuit pattern, and a plurality of input / output terminals 23 are properly arranged on one side thereof. The integrated circuit twin relay 22 is a miniature type used in a control board of a computer or the like as is well known to realize two control logics with one relay. Preferably, the input / output terminals 23 are collectively arranged in one place such that a plurality of wire harnesses H may be connected to one connector C connected thereto.

Two main surfaces of the upper cover 30 are provided with a plurality of pockets 31 to which the hooks 14 of the lower cover 10 are respectively coupled. A connection port 32 is formed on the upper surface of the upper cover 30 so that the connector C of the wire harness H can be coupled, and an input / output terminal of the relay module 20 is formed on the bottom surface of the connection port 32. A plurality of slots 33 are formed so that the 23 parts can be exposed respectively. The remaining reference numeral 15 is a fastening hole formed in the lug 11 of the lower cover 10.

In the vehicle IC relay box according to the present invention having such a structural feature, the relay-related circuits are not only modularized into electronic integrated circuits but also two control systems, unlike the conventional linear relays in which the relay 22 is independently configured as a simple circuit. It consists of twin relays that can realize logic simultaneously, reducing relay failure rate and improving performance, greatly reducing the number of circuits in automotive electronics and simplifying wiring (approximately 32% improvement).

In addition, the relay is composed of one ultra-small unit independent of the fuse box can significantly reduce the packaging (about 60%) as compared to the conventional configuration consisting of four relays as well as to achieve a light weight. In particular, the relay box can transmit all the input and output signals by one connector (C), the body mounting process of the operator is greatly reduced from four times to one time.

As described above, according to the present invention, the relay-related circuits of the vehicle can be integrated at the optimum position on the circuit path, and the wire harnesses of the complicated wiring can be integrated in one connector, thereby designing the wiring path of the electronics and securing the space. And installation work can be greatly improved.

Therefore, the present invention has a very excellent effect that greatly contributes to reducing the number of circuits, assembling and reliability of the vehicle electrical equipment.
