Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuse box, and more particularly to a fuse box mounted on a body of an automobile or the like and accommodating a plurality of blade type fuses.

[0002]

2. Description of the Related Art Conventionally, a plurality of blade-type fuses 6 have been used.
As a fuse box 51 for accommodating 1, there was the following one. That is, as shown in FIG. 3, a predetermined fuse storage hole 57 corresponding to each blade type fuse 61 (see FIG. 5) is formed on the surface of the fuse box 51. The fuse storage holes 57 extend in a direction substantially parallel to and substantially perpendicular to each other (see FIG. 3B).

[0003] Each of the blade-type fuses 61 is separately housed in each of the fuse housing holes 57.
Further, a fuse connection terminal 58 is introduced into the fuse storage hole 57 of the fuse box 51, and is connected to a metal terminal portion of the blade type fuse 61. In this conventional example, five blade-type fuses 61 are arranged and stored in a line.

When the blade type fuse 61 is disconnected for some reason, the blade type fuse 61 must be removed from the fuse box 51. In this case, the user pulls out the blade type fuse 61 from the fuse storage hole 57 with a finger or uses a special tool 60 or the like (see FIG. 4). Then, a new blade type fuse 61 is inserted into the fuse storage hole 57 in the fuse box 51.

[0005]

However, the above conventional example has the following disadvantages. That is, in the general fuse box 51, in order to increase the storage efficiency of the blade type fuses 61, the mounting pitch between the adjacent blade type fuses 61 is narrow, and it is difficult to pull out with a finger. . Further, in some cases, a special tool 60 for pulling out the blade type fuse 61 is required, and there is an inconvenience that a storage space for the tool 60 must be ensured. Especially,
If the special tool 60 is lost, a situation may arise in which the blade type fuse 61 cannot be removed.

When one of the plurality of blade-type fuses 61 is disconnected, each of the blade-type fuses 61 is temporarily removed, and the disconnection of the blade-type fuse 61 is visually confirmed. Have to do. This is because each blade type fuse 61 is inserted deeply in the vertical direction, and the broken portion of the blade type fuse 61 cannot be seen.

The blade type fuse 61 has the property of generating heat when an electric current flows. However, in the conventional fuse box 51, the heat generating portions 59 of the adjacent blade type fuses 61 are close to each other. Therefore, there has been a problem that the adjacent blade-type fuses 61 affect each other with respect to the temperature rise. In addition, since there is only a small space between the fuse housing hole 57 and the blade type fuse 61, there is a disadvantage that heat dissipation is low and thermal conditions are severe.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fuse box in which the disadvantages of the prior art can be improved, and in particular, the fuse box can be easily removed without sacrificing the storage efficiency.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a box-shaped fuse box body having a fuse storage hole on its surface and a fuse storage hole of the fuse box body are provided. In a fuse box including a blade type fuse to be stored and a fuse connection terminal connected to the blade type fuse, a fuse storage hole is formed at a predetermined inclination angle with respect to an outer wall surface of the fuse box body. A partition plate integral with the fuse box body is formed between the blade-type fuses, and a predetermined cutout is formed at an end of the partition plate corresponding to the blade-type fuse. .

[0010] With the above configuration, each blade type fuse is stored at a predetermined inclination angle with respect to the outer wall surface of the fuse box. Then, when any of the blade-type fuses is disconnected, it is checked which blade-type fuse is disconnected from the cutout portion of the partition plate located between the blade-type fuses. After checking, put a finger into the notch of the target blade type fuse and pull out the blade type fuse. Thus, the blade type fuse can be easily replaced without using a special tool.

Further, since the plurality of blade-type fuses are all installed obliquely and are exposed to the outside by the notches, the heat generated by the blade-type fuse itself is easily dissipated, and the other adjacent blade-type fuses can be dissipated. Does not affect mold fuse.

[0012]

An embodiment of the present invention will be described with reference to the drawings. In the fuse box 1 according to the present embodiment, as shown in FIG.
A fuse box main body 3 having the following shape, a blade type fuse 11 stored in the fuse storage hole 7 of the fuse box main body 3, and a fuse connection terminal 12 connected to the blade type fuse 11 are provided. . The fuse housing hole 7 is formed at a predetermined inclination angle with respect to the outer wall surface of the fuse box main body 3, and the partition plate 4 integrated with the fuse box main body 3 is formed between the blade type fuses 11. A predetermined notch 6 is formed at an end of the partition plate 4 corresponding to the blade type fuse 11.

More specifically, the fuse box body 3 is a box-shaped structure made of a material such as resin. The fuse box body 3 houses a blade-type fuse 11 that is actually connected between electric components (not shown). Here, the fuse is a component for preventing electrical components such as a vehicle (not shown) from being damaged. The specific functions are as follows. That is, when a short circuit occurs due to some reason in the electrical components, a large current flows in the circuit. At this time, if no measures are taken, the electrical components will be damaged by heat or the like generated by the short-circuit phenomenon.

The fuse prevents this breakage,
The fuse has a portion that is easily melted by heat in the conductive wire. When a large current flows through the fuse due to a short circuit, the fuse itself generates heat and a part of the fuse is disconnected. As a result, the circuit is opened, and damage to the electrical components is effectively prevented.

The fuse box 1 contains a large number of blade-type fuses 11 connected to various electrical components, and a plurality of electric wires 9 are introduced into the fuse box body 3. Examples of the types of electrical components actually connected include a wiper, a headlight, a direction indicator, and a radio (all not shown). Since the electrical components use different rated current values and the like, the blade type fuses 11 having various capacities are correspondingly used. Specifically, 5A
(Amps), 10A, 15A and 20A.
Of course, some have larger capacities.

Further, the fuse box body 3 has a structure shown in FIG.
As shown in FIG. 7, a fuse housing hole 7 is formed. The fuse storage hole 7 is provided with a plurality of blade-type fuses 11.
It is for storing. In particular, in the present embodiment,
A fuse storage hole 7 is formed obliquely downward from the upper surface of the fuse box 1, and the fuse storage hole 7 reaches the bottom side of the fuse box 1 (FIG. 1B).
reference). The fuse housing hole 7 has a size corresponding to the width of a blade type fuse 11 described later.

In the fuse accommodating hole 7, a predetermined partition plate 4 is provided between each blade type fuse 11. The partition plate 4 is provided for separately storing each blade type fuse 11. The partition plate 4 also has a predetermined inclination angle corresponding to the fuse storage hole 7. In the fuse box 1 according to the present embodiment, the fuse box body 3 and the partition plate 4
Are integrally formed of resin. Therefore, the same number of fuse storage holes 7 as the number corresponding to the blade type fuses 11 are formed.

A predetermined notch 6 is formed at an end of the partition plate 4 on the upper surface side of the fuse box main body 3. The notch 6 is formed at the center in the width direction of the fuse box body 3, and specifically, is cut out to such an extent that the center of the blade type fuse 11 is visible. Therefore, when the blade type fuse 11 is removed, a finger can be easily put on the blade type fuse 11.

A fuse connection terminal 12 to which a blade type fuse 11 is connected is also stored in the fuse storage hole 7 of the fuse box body 3. The fuse connection terminal 12 is actually firmly fixed in the fuse accommodating hole 7 so that it does not easily move even when a large force is applied. A predetermined electric wire 9 is connected to each of the fuse connection terminals 12, and each of the electric wires 9 is exposed on the back side of the fuse box body 3. The fuse connection terminal 12 is configured as a female type, and the metal terminal portion of the blade type fuse 11 is fitted. For this reason, the blade type fuse 11 does not come off due to the vibration of the vehicle or the like, but can be easily taken off when the user pulls out with a finger.

Here, the fuse box body 3 according to the present embodiment is configured so as to be able to accommodate a total of five blade-type fuses 11. However, the present invention is not limited to this, that is, the number may be smaller or larger. Also, the inclination angle is not particularly limited, and may be about 30 to 45 degrees.

Next, the function of the fuse box 1 configured as described above will be described. That is, in a normal use state, as shown in FIG.
Are housed in the fuse housing holes 7 of the fuse box body 3 and are connected to the fuse connection terminals 12. Then, a current is passed between electric components (not shown).

On the other hand, for some reason, a part of the plurality of blade type fuses 11 is disconnected.
The user of the vehicle knows that the blade-type fuse 11 has been disconnected due to the phenomenon that some of the electrical components have stopped functioning. In this case, the user checks the fuse box 1 and replaces the blade type fuse 11 if it is broken.

The operator confirms the disconnected blade type fuse 11 at the cutout 6 and extracts the target blade type fuse 11. At this time, since the blade type fuse 11 is disposed obliquely and is largely exposed by the cutout portion 6, it can be easily pulled out from the fuse connection terminal 12 as shown in FIG.

[0024]

As described above, according to the present invention, the fuse housing hole is formed at a predetermined inclination angle with respect to the outer wall surface of the fuse box main body, and the fuse box main body and the fuse box main body are interposed between the blade type fuses. In this method, an integral partition plate is formed, and a predetermined notch is formed at an end of the partition plate corresponding to the blade type fuse. For this reason, the blade type fuse can be pulled out by putting a finger on the notch portion, so that it is not necessary to provide a special tool, and there is an excellent effect that the manufacturing cost can be reduced.

Further, since it is possible to visually check whether or not the blade type fuse is disconnected through the cutout portion, the disconnected blade type fuse can be surely removed without removing each blade type fuse. An excellent effect is obtained that it can be replaced with a new one.

Further, since the blade type fuse is inclined at a predetermined angle with respect to the wall surface of the fuse box main body, the fuse box can be made thinner as compared with the conventional case where the fuse box is vertically mounted. This produces an excellent effect.

Further, since the surface of each blade type fuse is exposed to the outside by the cutout portion, the heat generated when the fuse is energized is easily dissipated, and the heat is easily transmitted to another adjacent blade type fuse. Since there is no influence, an excellent effect is obtained in that the reliability of the blade type fuse and the ease of designing the fuse box are improved.
