Description

Vertical Type Junction Box [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a junction box that is provided in an automobile and distributes power to a plurality of electric apparatuses. The junction box improves the structure of a PCB assembly mounted on one side of a passive junction box, The present invention relates to a vertical junction box that enables new functions to be added without re-manufacturing a junction box when a new vehicle is applied, diversification of options, and common use of a junction box.

Generally, a junction box refers to a device for distributing electric power to an engine room of an automobile and a plurality of electric device modules installed in an automobile.

Although there are slight differences according to the sizes of vehicles, there are about 20 to 40 relays and a dozen fuses in the automobile. If such relays and fuses are disposed in a dispersed manner, the structure becomes complicated and control becomes difficult.

Accordingly, a junction box is used as a device for integrating them in one place by using a printed circuit board (hereinafter referred to as PCB) and distributing electric power to each electric device module.

As shown in FIGS. 1 and 2, the junction box includes a housing 53 having a fixing bracket 54 on both sides in the width direction so as to be mounted on a vehicle, and a housing 53 having the same structure as the relay 51 or the fuse 52 (Not shown) installed on both sides of the housing 53 in the longitudinal direction thereof, a PCB 50 having a plurality of components and a circuit for connecting the components, and horizontally installed inside the housing 53, And a connector terminal (55) for inserting the connector terminal (55).

The connector can be divided into a power connector for power supply and a distribution connector for delivering the power distributed from the PCB 50 to each device of the vehicle.

In the junction box, some conductive terminals are connected by using a PCB, and the remaining terminals are directly connected by using a female / male connector, which is generally called a partial type junction box.

However, the conventional junction box shown in FIGS. 1 and 2 has a problem that it is difficult to additionally install a fuse or a relay due to a limited space when a new function is added to the junction box.

Accordingly, when various options are added, there is a problem that the junction box must be re-manufactured or an additional junction box must be manufactured.

In addition, the conventional junction box has a problem that it is difficult to share it with a new vehicle type because of its function and space problems.
