The present invention is designed to cut off the power supply due to the overload and the failure of the device while distributing the inside of the cubicle front panel and the inside of the electrical equipment in parallel, and inside the fuselage box in which the power connection terminal is installed outside. The inserts equipped with the wood holder and the terminal are made to slide in and out so that in the event of a fuse or trouble, the fuse can be easily replaced safely without shutting off the main power supply. The present invention relates to a fuse block case for an electric device, which can be easily distinguished from an abnormality.

The fuse block case used for the same purpose of the prior art has a fuse inserted in the plane between the input line and the output line, so when the fuse has a problem or trouble, it is troublesome to replace the fuse after shutting off the main power. This followed. The present invention is to allow the safe and simple to replace the fuse without breaking the main power in consideration of the above-mentioned conventional defects will be described in detail based on the accompanying drawings as follows.

1, 3, and 4, 1 is an insert inserted into the housing 2 in a sliding manner, and the insert 1 has a fuse holder 3 and a connecting terminal 4 therein. 4a, 4b is installed, and the connecting terminal of the insert 1 is connected to the inner terminals 6, 6a and 6b connected to the outer terminals 5, 5a and 5b of the housing 2. 4) (4a) and (4b) are made connectable.

7 is the main fuse inserted in the fuse holder 3 of the insert 1, and is provided between the connecting terminals 4 and 4a.

8 is an auxiliary fuse installed between the connecting terminals 4 and 4a of the insert 1, and the auxiliary fuse 8 is supported by the spring 10 on the other side of the fuse line 9, and thus the auxiliary fuse. In the case where the fuse line 9 of (8) is broken, the protruding line 17 of the distal end portion 11 protrudes toward the center hole 13 of the lid 12 by the spring 10 by the spring 10. At the same time, the connecting terminal connecting terminals 4a and 4b are electrically connected to each other by the contact 16 of the tip portion 11 so that the warning lamp or the buzzer 14 is operated. 15 is a handle mounted on the front center of the insert 1.

The present invention configured as described above is provided with a plurality of cusicles on the front panel and inside of the electric equipment to distribute the high voltage current inside, and to cut off the power when an overload and a failure of the device are caused. When the auxiliary fuse 8 is cut off, the power is cut off and at the same time, the contact 16 of the auxiliary fuse 8 is connected to operate the warning lamp or the buzzer 14, and particularly the front of the insert 1 of the corresponding block case. The protruding line 17 provided in the front end 11 of the auxiliary fuse 8 is pulled to the center hole 13 of the lid 12 so that the presence or absence of the abnormal fuse can be easily read.

In addition, once the main fuse (7) and the auxiliary fuse (8) is broken, to replace it, simply grasp the handle (15) on the front of the insert (1) and pull out the connecting terminals (4) (4a) of the insert (1). The fuse 1 is drawn out while the 4b is separated from the inner terminals 6, 6a and 6b connected to the outer terminals 5, 5a and 5b of the enclosure 2. (7) (8) can be easily replaced, and in this case, the entire circuit of the warning light or the buzzer 14 is in an open state so that it is not operated and the power of the tablet case is continuously connected. Therefore, after replacing the fuses (7) (8), if the insert (1) is pushed into the enclosure (2), the terminals (4) (4a) (4b) and (6) (6a) (6b) It is connected to the original again, which will be described in more detail as follows.

First, the power source is connected to the output terminals 4a and 6a through the connecting terminal 4 and the main fuse 7 of the insert 1 connected to the input terminals 5 and 6 inside and outside the enclosure 2. If the main fuse (7) is cut off at this time, the input terminal (5) (6) of the housing (2) and the connecting terminal (4) and the auxiliary fuse (8) of the insert (1) Through the output terminal 4a (6a) (5a) through the main unit is in normal operation, but if the auxiliary fuse (8) is cut off, the power input to the terminals (5) (6) (4) is cut off and contact Closing (16) to operate the warning light and the buzzer (15), that is, as shown in FIG. 5, the fuse line (9) one side end portion 11 of the auxiliary fuse (8) is a fuse body One side and the spring (10) is limited to the protruding line 11 is installed so as to protrude through the central hole 13 of the tip portion 11, the lid 12, and the inside of the central hole 13 of the lid 12 The fuse 4 of the auxiliary fuse 8 is connected to the terminal 4b. ) Is cut off, the power of the output terminal (4a) is cut off once, and the protruding line (17) of the distal end portion (11) is moved to the right side of the distal end portion (11) to which the fuse line (9) is connected by the spring (10). ) Protrudes brightly through the central hole 13 of the lid 12 so that the abnormality of the fuse can be easily read from the outside.

At this time, the distal end portion 11 of the fuse line 9 comes into contact with the central hole 13 of the lid 12, and the terminals 4 and 4b are connected to each other so that the warning lamp and the buzzer 14 are operated.

As described above, the present invention provides a main fuse 7 and an auxiliary fuse 8 in an enclosure 2 in which external and internal connection terminals 5, 5a, 5b, and 6, 6a, and 6b are installed. ) The insert (1) equipped with the main fuse holder (3) and the connecting terminals (4) (4a) and (4b) is made to slide in and out so that each terminal can be connected. The fuse can be replaced, and the auxiliary fuse 8 is cut off and at the same time, a protrusion line installed at the distal end of the fuse line 9 to the central hole 13 of the lid 12 installed on the front of the insert 1. By exposing (17), it is possible to conveniently read the abnormality of the fuse without opening the fuse block case one by one.
