The wire terminal (not shown) is also used as a connecting means for fastening the bolt (B) and the nut (N) so that power can be applied to the inside of the vehicle through the cable.

Hanging jaw 13 is formed on the inner surface 12 of the lower cover 10. The hanger 13 is formed to protrude from the inner surface 12 of the lower cover 10, the lower cover 10 is hooked with the coupling rib 29 of the main cover 20 to be described below And serves to couple the main cover 20.

 The hanger 13 is formed with a guide surface 13 '. The cross section of the guide surface 13 'is preferably formed in a shape corresponding to the inclined surface 29' of the coupling rib 29 to be described below. The guide surface 13 ′ serves to guide the coupling rib 29 when the coupling rib 29 is engaged with the hooking jaw 13.

A mounting surface 14 is formed on the bottom of the lower cover 10. The seating surface 14 is a portion on which the main cover 20 to be described below is seated.

A fixing rib 16 is formed on the seating surface 14 of the lower cover 10. The fixing rib 16 protrudes from the bottom surface of the lower cover 10 and extends upward when viewed in the center of the drawing. The fixed rib 16 is a part seated in the channel 25 of the main cover 20 to be described below. The fixed rib 16 is preferably formed to have a cross-section of approximately 'b' shape. This is to allow the channel 25 and the fixed rib 16 to be coupled to each other corresponding to the channel 25 of the main cover 20. The fixing rib 16 is inserted into the channel 25 of the main cover 20 to serve to couple the main cover 20 and the lower cover 10 to each other.

On the other hand, a mounting bracket 18 is formed on one side of the lower cover 10. The mounting bracket 18 is a part for coupling the fuse box 20 to the inside of the vehicle. That is, a fastening hole 18 'is formed in the mounting bracket 18 to be bolted to the inside of the vehicle.

The main cover 20 is coupled above the lower cover 10. The main cover 20 is a portion formed to cover a portion of the upper surface of the lower cover 20. The main cover 20 is formed to be located above the bus bar 11 so that the bus bar 11 is not exposed.

The main cover 20 has a shield 21 is formed. The shield 21 is a portion that substantially shields the bus bar 11. The shield 21 is formed to correspond to the inner shape of the lower cover 10. One side of the upper surface of the shielding portion 20 is provided with a fuse mounting portion 22a on which a fuse is mounted, a relay mounting portion 22b on which a relay is mounted, and a connector mounting portion 22c on which a connector housing is mounted.

The shielding portion 21 has a tool passing portion 23 is formed. The tool passing portion 23 is formed by cutting a part of the shield 21. The tool passing portion 23 is a portion formed to fasten the bolt (B) and the nut (N) of the fuse box terminal. That is, the tool passing portion 23 is to avoid the interference by the main cover 20 when fastening the bolt (B) and the nut (N).

An extension portion 24 is formed at an adjacent portion of the tool passing portion 23. The extension part 24 is a thin and long part of both sides of the shielding part 21 adjacent to the tool passing part 23. That is, the extension part 24 is formed extending from the shielding part 21 in a cantilevered shape. The extension part 24 is a remaining part in which the tool passing part 23 is formed in the shielding part 21 and is seated on the seating surface 14 of the lower cover 10.

The channel 25 is formed to be opened to one side of the extension 24. The channel 25 is a portion corresponding to the fixed rib 16 and is coupled to the fixed rib 16. That is, the fixing rib 16 is inserted into the channel 25 to guide the main cover 20 to the position where the main cover 20 is coupled to the lower cover 10 and prevent the deformation of the extension part 24.

Reinforcing ribs 27 are formed on the inner surface of the main cover 20 in contact with the inner surface 12 of the lower cover 10. The reinforcing ribs 27 are formed to a predetermined thickness toward the inner surface of the main cover 20. Since the main cover 20 is made by injection molding, the overall shape can be deformed, and in particular, since the extension part 24 is thin and long, the shape can be easily deformed, thereby forming the reinforcing ribs 27 so that To prevent deformation or breakage of the main cover 20.

An inner surface of the main cover 20 adjacent to the channel 25 is formed to protrude a locking projection 27 ', as shown in FIG. The locking protrusion 27 ′ serves to prevent play between the fixed rib 16 and the reinforcing rib 27.

That is, the coupling rib 29 is fastened to the hanger 13 so that the edge surface 26 of the main cover 20 is in close contact with the inner surface 12 of the lower cover 10.

The coupling rib 29 is formed with an inclined surface 29 'corresponding to the guide surface 13' of the hanging jaw 13. The inclined surface 29 'is guided by the guide surface 13'.

Hereinafter will be described in detail the operation of the coupling structure of the fuse box for a battery according to the present invention having the configuration as described above.

First, a process of mounting the bus bar 11 on the lower cover 10 will be described. First, the bus bar 11 is seated on the lower cover 20. The fuse box terminal and the bus bar 11 are coupled to each other by a bolt B and a nut N provided at one side of the fuse box terminal. The bus bar 11 is seated and fixed to the lower cover 10, and the fuse box terminal is also fixed to the lower cover 10. In general, the fuse box terminal is seated on the lower cover 10 in a state in which the bus bar 11 is installed on the lower cover 10. Then, a wire terminal is connected to one side of the bus bar 11.

Next, the main cover 20 is coupled above the lower cover 10. At this time, the concave inlet portion 28 formed in the main cover 20 is positioned so as to face the hanger projection 13 formed in the lower cover 10. In this state, the main cover 20 is moved toward the lower cover 10. In the present embodiment, since the plurality of concave portions 28 and the hanging jaw 13 are respectively formed, it is necessary to insert the corresponding hanging jaw 13 into each concave portion 28.

When the main cover 20 is moved downward while the edge surface 27 of the main cover 20 and the inner surface 12 of the lower cover 10 face each other, the hooking jaw 13 And the coupling rib 29 are walked with each other. That is, when the hooking jaw 13 and the coupling rib 29 are in contact, the coupling rib 29 passes over the hooking jaw 13. In this case, the hooking jaw 13 and the coupling rib 29 are walked with each other.

At this time, the fixed rib 16 is inserted into the channel 25. The main cover 20 is fixed to the lower cover 10 by engaging the channel 25 with the fixed rib 16. In this case, the edge surface 26 of the main cover 20 and the inner surface 12 of the lower cover 10 are in close contact with each other, and the relative movement between the main cover 20 and the lower cover 10. This is avoided. This appearance is well illustrated in FIG. 5.

In the present specification, the battery fuse box has been described using a name, but any name may be used as long as it serves to distribute power and has a function of preventing overcurrent from flowing to each component.

In the seating structure of the fuse box for the battery according to the present invention as described in detail above, the following effects can be obtained.

In the present invention, the fixing rib and the channel which can fix the extension of the main cover to the lower cover are formed in a position corresponding to each other to prevent the flow between the lower cover and the main cover. Therefore, the coupling between the main cover and the lower cover is firmly maintained, thereby improving the operational reliability of the fuse box.

And in the present invention, the engaging rib and the hook jaw is hooked to each other in the recessed portion formed in the main cover. Accordingly, the surfaces facing each other of the main cover and the lower cover are in close contact with each other to prevent relative movement between the main cover and the lower cover, and the bus bar may be shielded without play.
