Description

Multi-fuse}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-fuse, and more particularly, to a multi-fuse to which a conventional general fuse is applied and a fuse can be individually replaced.

There are a variety of electrical products that use power from a vehicle. For example, there are motors, spark plugs, and the like. These electrical components require power for their operation. These electrical components are supplied with power from a battery or generator via a fuse box.

The fuse box is provided with a fuse for preventing an overcurrent from flowing into each electrical component. As a result, power is supplied to each electric component through a fuse, and when an overcurrent flows, the power supply to the electrical component is cut off because the fuse is blown.

Among these fuse boxes, the multi-fuse supplies electric power to a plurality of electric components and prevents the overcurrent from flowing into each of the electric components. That is, the multi-fuse actually plays the same role as a combination of a plurality of fuses.

In the interior of the multi-fuse, a bus bar and a plurality of terminal blocks for interrupting the power supply connection are provided when an overcurrent flows through each electrical component, and the power supply is cut off by breaking the terminal block.

However, in the conventional multi-fuse, since a plurality of fuse portions are connected to each other and any one of them is disconnected, the entire multi-fuse must be replaced, and therefore, the replacement cost of the components is high and the parts are wasted.

In addition, when the size and the size of the multi-fuse applied to the vehicle differs depending on the type of vehicle or the like, the multi-fuse itself must be newly designed and manufactured.

Of course, in some cases, the portion corresponding to the identification cover 13 may be omitted so that the storage space 12 may be exposed to the outside, and the identification cover 13 itself may be omitted.

A supporting portion 15 protrudes toward the center of the accommodating space 12 in the accommodating space 12 of the fuse housing 10. The support portion 15 protrudes from the inner surface of the storage space 12 and extends along the longitudinal direction of the storage space 12. The support portion 15 includes a first extension portion of the individual fuse F F2. In this embodiment, two support portions 15 are provided in pairs.

A guide channel (18) is formed on both sides of the storage space (12). The guide channels 18 are formed at positions facing each other in the storage space 12 and serve to guide both sides of the individual fuses F in the process of being inserted into the storage space 12. [ In this embodiment, the guide channels 18 are formed between a pair of guide ribs 17 protruding from both side surfaces of the storage space 12.

The upper cover 30 is coupled to the upper portion of the fuse housing 10. The upper cover 30 has a long and flat cover body 31 and is coupled to an upper portion of the fuse housing 10 to shield one side of the storage space 12. [ As shown in FIG. 2, the upper cover 30 covers and covers the entire bus bar 40 except the connection terminal 47 of the bus bar 40, which will be described below.

A bus bar 40 is coupled to the upper portion of the fuse housing 10. The bus bar 40 is made of a metal material having high electrical conductivity. As shown in FIG. 4, the bus bar 40 is long in one direction to correspond to the upper portion of the fuse housing 10.

The bus bar 40 includes a bus bar body 41 extending in one direction and connection legs 45 extending from the bus bar body 41 to the respective storage spaces 12. The connecting legs 45 may be formed in a number corresponding to the number of the accommodating spaces 12 and may protrude from the bus bar body 41 and at least part of the connecting legs 45 may be inserted into the accommodating space 12. [ . The connecting leg 45 protrudes in a cantilever shape from the bus bar body 41 and is elastically deformable

At this time, a contact portion 46 protrudes from the connection leg 45 of the bus bar 40. The contact portion 46 is formed by protruding one side of the connecting leg 45 and being extended through the entirety of the connecting leg 45. The contact portion 46 is a portion substantially in contact with the first extending portion F2 of the individual fuse F and is electrically connected to the first extending portion F2 in a line contact manner. In this embodiment, the contact portion 46 is provided in a bead shape elongated to one side, but can be modified in various ways if it has a protruding shape.

5, the connection leg 45 of the bus bar 40 is elastically deformed more strongly than the first extension F2 of the individual fuse F by the protrusion of the contact portion 46, So that they are in close contact with each other. The first extended portion F2 of the individual fuse F is supported by the support portion 15 of the accommodating space 12 at its rear face and is pressed by the elastic force of the connection leg 45 in this state The first extended portion F2 and the contact portion 46 can be brought into stronger contact with each other. As a result, a more stable electrical connection is established between the bus bar 40 and the individual fuse F.

A connection terminal 47 is provided at one side of the bus bar 40. The connection terminal 47 protrudes outside the upper cover 30 and is electrically connected to an external power source such as a battery.

A separate fuse F is inserted into the fuse housing 10. A plurality of individual fuses (F) are provided, and they form a multi-fuse. The plurality of individual fuses F are respectively inserted and fixed in the storage space 12. The individual fuses F are generally widely used fuses, and may be fuses of various kinds and sizes. For example, the capacity of the individual fuse F may vary depending on the user's selection, and the capacity between the plurality of individual fuses F accommodated in the plurality of storage spaces 12 may be different from each other .

The individual fuse F includes a fuse body F1 having a free end and a first extension F2 and a second extension F3 provided on both sides of the fuse body F1. The first extended portion F2 extends from one side of the fuse body F1 and is connected to the bus bar 40.

The first extension F2 is electrically connected to the connection leg 45 of the bus bar 40 and the second extension F3 is electrically connected to the FF terminal T. The second extension F3 is electrically connected to the FF terminal T, T are connected to the parts (not shown), so that the external power can be delivered to the respective parts via the bus bar 40 / individual fuse F / FF terminal T. [

An F-F terminal T is provided on one side of the storage space 12 of the fuse housing 10 opposite to the bus bar 40. The second extension F3 of the individual fuse F is inserted into one side T1 of the FF terminal T in the present embodiment, And the terminal portion of the component is inserted into the other side T2.

Hereinafter, an assembling process of the multi-fuse according to the present invention will be described in detail with reference to the drawings.

First, the operator inserts the F-F terminal (T) into the lower portion of the fuse housing 10. [ More precisely, the F-F terminal T is inserted into one side of the fuse housing 10 which opens downward in the receiving space 12. Although not shown, the F-F terminal T may be fixed with a fixing part for fixing one side of the F-F terminal T to the storage space 12. This is shown in Fig.

Next, an individual fuse F is inserted from the top of the fuse housing 10. The individual fuse F is inserted downward from the opened top of the storage space 12, at which time the second extension F3 is inserted first. Of course, since the first extension F2 and the second extension F3 of the individual fuse F are not distinguished, the first extension F2 may be inserted first.

Since the individual fuses F are inserted into the guide channels 18 of the storage space 12 on both sides thereof, they can be inserted while being guided in a predetermined direction. When the individual fuse F is completely inserted into the storage space 12, the first extended portion F2 of the individual fuse F is held in contact with the support portion 15 protruding into the storage space 12, The second extended portion F3 is inserted into one side T1 of the previously inserted FF terminal T. [

At this time, the operator can insert the individual fuses F into the storage space 12 by the desired position and number. In other words, the individual fuses F can be selectively inserted according to the environment and conditions in which the multi-fuses are used. In FIG. 2, four individual fuses F are shown, Respectively. Of course, the capacity of the individual fuse F may vary depending on the use environment or conditions. This is shown in Fig.

Next, the bus bar 40 is inserted into the upper portion of the fuse housing 10. The bus bar 40 is lowered with the connection legs 45 facing the storage space 12 so that a plurality of connection legs 45 are inserted into the storage space 12.

At this time, the contact portion 46 provided in the connection leg 45 of the bus bar 40 is brought into contact with the first extended portion F2 of the individual fuse F, and the first extended portion F2 is supported by the supporting portion 15, the operator has to push the connecting leg 45 of the bus bar 40 while elastically deforming the connecting leg 45 to some extent. The connection legs 45 of the bus bar 40 and more precisely the contact portions 46 of the connection legs 45 can be strongly adhered to the first extension F2 of the individual fuse F. [

Then, the operator covers the bus bar 40 by covering the upper part of the bus bar 40 with the upper cover 30. Of course, if the bus bar 40 is integrally formed with the upper cover 30 through a method such as insert injection, the process of separately assembling the upper cover 30 may be omitted. This is shown in FIG.

Lastly, external power is directly or indirectly connected to the connection terminal 47 of the bus bar 40, and a part of the component of the F-F terminal T is connected to the other end T2.

If any one of the individual fuses F is cut off due to the overload of the parts in the process of using the multi-fuse, the operator can easily identify it through the identification cover 13.

Then, the operator can continue to use the multi-fuse by removing the upper cover 30 and replacing only the individual fuse F that needs to be replaced, so that it is not necessary to replace the multi-fuse itself.
