The present invention relates to a fuse box terminal, and more particularly to a fixing structure of the fuse box terminal coupled to the fuse box of the vehicle.

BACKGROUND ART In general, automotive batteries are mounted on vehicles regardless of gasoline or diesel, and are used as power sources for starting, ignition, lighting, and other electrical equipment of an engine. The fuse box terminal is used as an electrical connection means by being coupled to the battery so that power can be applied to the start, ignition, lighting and other electrical equipment through the cable as described above.

Also, in recent years, as the vehicle is advanced and the electric devices inside the vehicle are complicated, a fuse box has been used a lot. The fuse box is a collection of fuses associated with various electrical components, and is installed in an automobile, for example, to prevent overcurrent from flowing through various electrical components of the automobile.

In this case, the fuse box may be directly connected to the battery. That is, the fuse box is mounted on an upper surface of the battery, and the fuse box terminal seated inside the fuse box is coupled with a terminal provided in the battery to supply power from the battery to the inside of the vehicle.

However, the prior art as described above has the following problems.

The fuse box terminal is seated in the fuse box, but is not directly connected through a fastener or the like. Therefore, when an external force such as vibration is transmitted to the coupling structure of the fuse box terminal while the vehicle is running, the flow of the fuse box terminal is generated. That is, the fuse box terminal flows in the up and down direction, or a rotation occurs due to relative movement, and thus the electrical contact between the fuse box terminal and the battery terminal is broken or a spark occurs.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, to ensure that the fuse box terminal is firmly coupled to the terminals of the battery.

According to a feature of the present invention for achieving the object as described above, the present invention is a fuse having a fuse box terminal, a seating portion in which the fuse box terminal is seated, and a fuse having a spacer coupling hole formed through one side of the seating portion; And a spacer inserted into the spacer coupling hole to fix the box and the fuse box terminal.

The spacer coupling holes are respectively formed at both sides of the seating portion, and the two spacers are respectively coupled to the spacer coupling holes.

The spacer coupling hole is formed with guide protrusions on the left and right sides, respectively.

The spacer is formed to extend in a direction orthogonal to the direction in which the fixed blade extends from the upper end of the body to secure the fuse box terminal and the body formed in each of the two stages in the left and right directions to engage with the guide projection. It consists of a push wing.

A fixing jaw is further formed at one end of the fuse box to prevent the flow of the fuse box terminal, and the fixing jaw is formed to be symmetrical to the left and right sides of the fixing jaw to fix one end of the fuse box terminal at each of the left and right sides.

According to the fixing structure of the fuse box terminal according to the present invention having such a configuration, even if an external force is applied to the assembly of the battery and the fuse box, the flow of the fuse box terminal is prevented, there is an advantage that the operation reliability of the fuse box terminal is increased.

Hereinafter, a preferred embodiment of the fuse box terminal fixing structure according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an exploded perspective view of a preferred embodiment of the fuse box terminal fixing structure according to the present invention, Figure 2a is a perspective view showing the main configuration before the spacer of the embodiment of the present invention is coupled, Figure 2b The perspective view showing the main part configuration after the spacer of the embodiment is coupled is shown, Figure 3 is a perspective view of the fuse box terminal of the present invention embodiment, Figure 4 is a side view showing the main part configuration of the present invention embodiment. .

As shown in these figures, the vehicle is provided with a battery 1 for supplying power to the engine for starting, ignition, lighting and other electrical components. In this case, the battery 1 is provided with a battery terminal 2 protruding to the outside for electrical connection with the electrical component side.

The fuse box 10 is connected to the battery terminal 2. The fuse box 10 is configured by coupling the upper cover 14 and the lower cover 15 to the main cover 13 to which various components can be mounted.

The fuse box terminal 20 is seated on the lower cover 15. As shown in FIG. 3, the fuse box terminal 20 includes two coupling rings A and B (21 and 22), and the coupling rings A and B (21 and 22) respectively have battery terminals 2.

At this time, the coupling rings A, B (21, 22) is formed in an arc shape of one end is open, each having an extension portion A, B (21 ', 22') extending from one side open.

The extension portions A and B 21 'and 22' are respectively tightened or opened at their ends, so that the diameter of the insertion hole 23 is reduced or increased so that the battery terminal 2 and the fuse box terminal ( 30) Adjust the binding between. In addition, an interference avoiding part 24 is formed in each of the extension parts A and B 21 'and 22', and the bolt A 31 to be described later penetrates the extension parts A and B 21 'and 22'. To engage with nut A (32).

As shown in FIG. 3, the fastening part 25 is separate from the coupling rings A and B (21 and 22), and the extension parts A and B (21 'and 22') are coupled to the coupling ring A. Both ends of the two extension portions A, B (21 ', 22') are wrapped in a direction orthogonal to the direction extending from the B (21, 22).

And a through hole (not shown) formed with a female thread is formed on the upper end of the tightening portion 25. The through hole is penetrated from below by the bolt A 31 and the bolt A 31 is coupled to the nut A 32. That is, the bolt A, which has a thread from the end of the body to a predetermined portion, passes through the interference avoiding portion 24 and the through hole, respectively, from below to above, and is coupled with the nut A 32. At this time, as shown in Figure 3, the diameter of the body of the bolt A (31) is larger than the interval between the ends of the extension A, B (21 ', 22'). Therefore, the combination consisting of the tightening portion 25, the bolt A (31) and the nut A (32) is not separated from the coupling rings A, B (21, 22).

  At this time, the bolt A (31) is formed with a substantially rectangular head portion 33. The head part 33 is fixed to the lower cover 15, and the extension part B 22 ′ is seated. Accordingly, the extension parts A and B 21 ′ and 22 ′ are positioned in a space formed by the head part 33 and the groove 26.

At this time, as shown in Figure 4, the tightening portion 25 is formed with a substantially trapezoidal groove 26, the lower end is opened and the gap is narrowed upward. At this time, the two extensions A, B 21 'and 22' are positioned to overlap each other in the groove 26. Since the groove 26 is narrowed toward the upper side, when the tightening portion 25 is lowered by tightening the nut A 32, the interval between the ends of the extension portions A, B (21 ′, 22 ′) is accordingly tightened. Also narrowed serves to reduce the diameter of the insertion hole (23).

Bolts B 34 are provided at the other ends of the coupling rings A and B 21 and 22 where the bolts A 31 are provided. The bolt B 34 is coupled to the nut B 35 to serve to couple the fuse box terminal 20 and the bus bar 40. The busbar 40 serves to connect two or more circuits individually or to connect several isometry points in a system. At this time, the bus bar 40 is seated on the lower cover 15 together with the fuse box terminal 20.

One side of the lower cover 15 is formed with a seating portion 41 in which the fuse box terminal 20 is located. A recess 42 is formed in the seating part 41 so as to correspond to the bottom surface of the fuse box terminal 20 so that the fuse box terminal 20 is fitted therein. At this time, the through hole 43 is formed in the center of the seating portion 41 to correspond to the insertion hole (23).
