When the electric connection box 31 is fixed to the inner wall of the vehicle body, first, the electric connection box 31 is gripped by one hand and held at a predetermined position on the inner wall of the vehicle body. Bolts were inserted through bolts 36 and 37 to perform bolting work.

[0005]

However, when holding the electric connection box 31 with one hand, the short side of the electric connection box 31 often has a considerably long width (W1), and it is difficult to hold the electric connection box 31 with one hand. Met. Therefore, the operator may perform the mounting operation while holding the relay 38 which is easy to grasp.

For this reason, there has been a problem that the relay 38 may be damaged, fall off, or cause a poor contact. The present invention has been made in order to solve the above problems, and an object of the present invention is to easily attach the electric junction box by holding it with one hand without impairing the functions of electrical components such as a relay. It is to provide an electric junction box which can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIG.
The electric connection box 11 includes a lower case 12 in which electric components and the like are stored, and an upper case 13. The lower case 12 has a box shape with an open top, and is formed so that the upper case 13 can be fitted thereto.

As shown in FIGS. 1 and 2, a mounting arm 14 is formed at the upper end of the lower case 12 so as to protrude, and a bolt insertion hole 15 is formed in the mounting arm 14. At the upper end of the upper case 13, a mounting arm 16 is formed so as to protrude so as to be inclined. The mounting arm 16 has a bolt insertion hole 17 formed therein. Then, a bolt (not shown) is inserted through the bolt insertion holes 15 and 17 of the mounting arms 14 and 16 and screwed to the inner wall of the vehicle body, thereby connecting the electric connection box 1 to the inner wall of the vehicle body.
1 is fixed.

A fuse mounting portion 18 is provided on the upper surface of the upper case 13, and a plurality of fuses 19 are mounted on the fuse mounting portion 18. Also, upper case 1
A relay mounting portion 20 is provided on the upper surface of the device 3, and a plurality of relays 21 are mounted on the relay mounting portion 20.

Further, a peripheral wall 22 is formed on the upper case 13 so as to surround the relay mounting portion 20, and the width W2 of the peripheral wall 22 on the short side is set to be lower.
And the height H2 of the peripheral wall 22 is higher than the height of the relay 21 mounted on the relay mounting portion 20 and the height H1 of the fuse mounting portion 18. The width W2 and the height H2 of the peripheral wall 22 are formed so as to be easily gripped by one hand. Further, the fuse mounting portion 18 is provided on the peripheral wall 2.
2 are disposed outside.

Next, the operation and effect of this embodiment will be described. In the present embodiment, the peripheral wall 22 is formed so as to surround the relay mounting portion 20 together with the relay 21, and is formed so as to be gripped by one hand. Therefore, the relay 21
Not only the protective role of the
There is also an effect that the peripheral wall 22 can be easily gripped with one hand. Therefore, since there is no need to grip the relay 21, the work of attaching the electric connection box 11 to the inner wall of the vehicle body can be easily performed without impairing the function of the relay 21. In the upper case 13 of the electric connection box 11, the fuse mounting portion 18 is disposed outside the peripheral wall 22. For this reason, the fuse 1
9 can be easily attached and detached. Also, fuse 1
9 is often replaced as compared with the relay 21, and therefore, by disposing the fuse mounting portion 18 on the outer side of the peripheral wall 22, the fuse 9 can be conveniently used as an electric connection box.

The present invention is not limited to the above-described embodiment, but may be implemented as follows, with a part of the configuration being appropriately changed without departing from the spirit of the invention. As shown in FIG. 3, a flange 23 is formed on the upper edge of the peripheral wall 22 as a means for facilitating gripping. In addition, as shown in FIG. 4, gripping holes 24 as means for facilitating gripping are formed on each long side of the peripheral wall 22. Further, as shown in FIG. 5, a projection 25 as a means for facilitating gripping is formed on each long side of the peripheral wall 22 in a plate shape.

In the case of such a construction, the means 23, 2 formed on the peripheral wall 22 for facilitating the gripping are provided.
4 and 25, the peripheral wall 22 can be more securely gripped with one hand, so that the work of mounting the electric connection box 11 can be performed more easily and quickly. In the above embodiment, the peripheral wall 22 is connected to the relay mounting portion 20.
Is formed so as to surround with the relay 21, but a part of the peripheral wall 22 may be cut or omitted.
In particular, if the short side peripheral wall 22 is cut or omitted, the manufacturing cost of the electric connection box 11 can be efficiently reduced. In the above-described embodiment, one peripheral wall 22 is formed so as to surround the plurality of relay mounting portions 20, but two or more peripheral walls 22 are formed so as to surround the relay mounting portions 20. Is also good. In the above embodiment, the peripheral wall 22 is formed in a square frame shape, but the shape of the peripheral wall 22 may be curved or bent, and the shape of the peripheral wall 22 is particularly limited to a square frame shape. Not something.

Incidentally, the "electric junction box" referred to in the present specification is:
It means any form of intervening existence provided to house various electric components and connect them to wire harnesses and other wiring, and is limited to so-called junction blocks (J / B) is not.

[0018]

Since the present invention is configured as described above, it has the following effects. According to the invention described in claim 1, it is possible to reliably grip the peripheral wall with one hand, without gripping the relay, it is possible to perform the work for attaching the grips the wall for example, such as a vehicle body. Therefore,
Without impairing the function of the relays can be mounted easily by grasping the peripheral wall with one hand. Further, since the peripheral wall is formed higher Ri <br/> by relays, it is possible to protect the relay by the peripheral wall.

Further, since the fuse mounting portion outwards of the peripheral wall is disposed, it is possible to fuse the detachable relative to the fuse mounting portion easily.

According to the invention described in claim 2 , according to claim 1,
In addition to the effects of the invention described in (1), by forming a flange on the upper end edge of the peripheral wall as a means for facilitating gripping on the peripheral wall, the peripheral wall can be more securely gripped with one hand, so that electrical connection can be made. The box mounting operation can be performed more easily and reliably.
