And, the alternator terminal 150 exposed to the outside of the block 110 through the fastening hole 260, the installation pin 270 is inserted into the fastening hole 260, the body 10 and the alternator terminal ( 150) detachably combined.

In this case, the installation pin 270 is inserted into the power supply terminal 280 to be electrically connected to the alternator terminal 150.

The power supply terminal 280 is a general ring terminal.

In particular, the power supply terminal 280 is inserted into the installation pin 270 and assembled to contact the alternator terminal 150 to directly connect the power supply terminal 280 to the alternator terminal 150. This is to simplify the interconnect structure while maintaining contact with each other even when the vehicle shakes.

If the maximum current is generated within the allowable member 170 of the power connection terminal group 160, the blocking member 180 may be shorted to protect the battery.

Therefore, the power connection terminal group 160 connected to the alternator terminal 150 through the intermittent member 170 on the left side of the block 110 based on the blocking member 180 is connected to the electrical appliance that is operated only during startup. Preferably, the energizing terminal group 130 connected to the battery terminal 120 through the short circuit member 140 on the right side of the block 110 on the basis of the blocking member 180 and the electrical equipment to be operated even when the start stop It is preferred to be connected.

It is preferable to use a strip-shaped copper foil which connects the alternator terminal 150 with.

At this time, the intermittent member 170 and the blocking member 180 apply a heat-transfer member 220 which is a high-heat material on the surface in order to short-circuit in a short time when the overload occurs.

The heat transfer member 220 is heated in a short time by the heat generated when the overload occurs to thereby short-circuit the intermittent member 170 and the blocking member 180 through this.

The heat transfer member 220 is preferably made of tin having a property of further heating the heated material.

In particular, the intermittent member 170 and the blocking member 180 form a cohesive hole 230 to cure in a cohesive state of the heat transfer member 220.

Therefore, the heat transfer member 220 is applied to the surface of the intermittent member 170 and the blocking member 180 in a softened state to have fluidity, and then aggregated around the cohesion hole 230 at the time of curing.

Thus, when the overload occurs, the interruption member 170 and the blocking member 180 are short-circuited to the aggregation hole 230.

In particular, the block 110 preferably forms a transparent window 250 such that whether the intermittent member 170 and the blocking member 180 are short-circuited, similarly to the short circuit member 140, can be visually confirmed.

In addition, the block 110 is the arbitrary intermittent member 170 and the blocking member 180 is melted and each of the intermittent members 170 and so that the short-circuit member 140 and the intermittent member 170 does not affect during the short circuit. The partition wall 240 is formed therein to partition the blocking members 180 from each other.

Therefore, the multi-fuse 100 of the above configuration is formed by integrally forming the battery terminal 120, the alternator terminal 150, the conduction pins (131, 132, 133) and the power connection pins (161, 162, 163, 164, 165) integrally in one block (110).
