Description

Fuse with relay box for automobil}

The present invention relates to a fuse and a relay device of an automobile, and more particularly, to form a power distribution and branch circuit integrally in the body of the box to reduce the number of parts, and to prevent the terminal push and contact failure of the automobile Relates to a fuse and a relay box.

In general, in order to prevent excessive current from flowing to the electric component, a large number of fuses which melt instantly when the current exceeds a specified value and cut off the circuit, and operate when the input value reaches a predetermined value, A box-type fuse and a relay box are provided in which dozens of relays are assembled and stored to open and close the circuit.

As shown in FIG. 1, the fuse and relay box 1 includes a main body 2 in which a plurality of fuses and relays are assembled, an upper cover 3 for opening and closing the main body 2, and the main body 2. The lower cover 4 is opened and closed, for example, which can be mounted on a wheel house of an automobile. That is, a conventional fuse and relay box of the prior art is formed of a plastic injection molding and is configured such that terminals and bars of simple structure are installed.

That is, the conventional fuse and relay box has a bus bar structure in which a plastic injection molding and a plurality of power supplies or supply circuits are connected. For example, the number of circuits that can be employed in the same area is relatively small, about 60. In addition, since power must be distributed using terminals, the body of a conventional box must be procured in line integrally with the wheel house assembly. Accordingly, the increase in the overall weight of the wheel house assembly and the component parts are many, and thus the workability of the line is disadvantageous, and there is a problem in that the service is unreasonable because the entire assembly must be supplied even in the case of partial defects.

In addition, in terms of the design of the wheel house assembly, since the fuse and the relay box are integral to the wheel house assembly, it is necessary to bypass a part of the circuit, which reduces design efficiency, and in addition, the branch body of the box body can be handled by Since there is no way to deal with the bypass circuit by pulling the circuit directly to the outside, there is a problem that the overall cost of the entire wheel house, such as using an external joint connector, increases.

In addition, in the conventional fuse and relay box, terminals are pushed and poor contact results in deterioration of product quality and reliability, and the wiring of the entire engine room is not clean.

Therefore, the present invention has been invented to solve the above-described problems, the object of the present invention is to form a power distribution and branch circuit integrally in the body to reduce the number of parts, the vehicle that can prevent terminal push and contact failure To provide fuses and relay boxes.

It is another object of the present invention to provide a fuse and relay box for an automobile in which a process for a wheel house assembly is omitted and a single part can be replaced and repaired.

Still another object of the present invention is to provide a fuse and relay box for an automobile in which the weight and manufacturing cost of the entire wheel house are reduced.

Such objects include: a fuse and a relay box for an automobile, the body being formed in a box shape and having a plurality of fasteners protruding outward from a portion of a corner portion thereof; A plate installed in the main body and having a plurality of fuses and relays respectively connected to the electronic parts of the vehicle; An insulating plate integrally formed on a rear surface of the plate and stamped with a plurality of bus bar patterns to which distribution and branching circuits are connected; And a cover installed on the main body so as to be openable and closeable, and including a cover on which a label printed on a label corresponding to each fuse and relay provided on the plate is attached to a rear surface thereof. Can be.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 2, the fuse and relay box according to the present invention includes a main body 10. The main body 10 is preferably formed in a box shape. Of course, a plurality of fasteners 12 to which a cover, which will be described later, may be protruded to the proximal portion of a corner portion of the main body 10.

As shown in FIG. 3, the main body 10 is provided with a plate 18 on which a plurality of fuses 14 and a relay 16 are installed. Of course, each of the fuses 14 and the relay 16 is connected to the respective electrical components and circuits of the vehicle and when the current exceeds the specified value flows instantly melts the circuit, and when the input value reaches a predetermined value It acts to open and close other circuits.

In particular, on the back surface of the plate 18, for example, dozens of bus bar patterns 20 are stamped to form a stamped insulating plate 22 integrally. Each of these bus bar patterns 20 is preferably stamped on the insulating plate 22, for example, a printed circuit board manufacturing method.

Meanwhile, as shown in FIG. 5, the cover 24 is fixed to the main body 10 so as to be openable and closeable. In particular, inside the cover 24, the location, use, capacity, etc. of each fuse installed in the plate 14 of the main body 10 are divided into the partitions 26, and the printed label 28, for example, adhesive It is preferable to attach by.

Hereinafter, the operation mode of the fuse and the relay box for a vehicle according to the present invention will be described in detail.

In the main body 10 of the fuse relay box for automobiles according to the present invention, for example, dozens of bus bar patterns 20 and insulating plates 22 may be used to cleanly distribute power distribution and branch circuits. That is, since the distribution and branch circuits can be adopted using dozens of stamped bus bar patterns 20 inside the main body 10, the number of circuits that can be employed in the same space can be maximized, thereby manufacturing the overall wheel house. The process can be simplified. In addition, the main body can be procured and assembled independently of the wheel house assembly, and can be manufactured separately from the wheel house assembly.

In addition, one body can be used to insert and discharge circuits into the wheel house assembly, thereby reducing the overall number of parts in the box. In addition, since the branch circuit can be processed to use the bus bar pattern stamped in a single unit of the box, there is no need to bypass the circuit, so that a separate connection means such as a joint connector can be omitted.

In addition, since a circuit can be connected to the back of the box by using a connector, it is possible to prevent terminal pinching and contact failure.

As a result, according to the automotive fuse and relay box according to the present invention, it is possible to process the branch circuit internally, does not require a separate connection means, the terminal push and contact failure is prevented to improve the productability and reliability It is effective.

In addition, since the wheel house can be manufactured and processed separately, workability is improved.

While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
