Description

Technology Field

[0001] The present invention relates to a connecting device for a wire fuse. Background Technology

[0003] The following problem occurs because the wires are inserted into a cylindrical sleeve body at both ends of the wire fuse and the wires and fuses are connected in mid-air using a crimping tool and a die.

[0004] When a fuse melts due to an overcurrent, there is a persistent risk of increased construction costs and safety accidents resulting from prolonged high-altitude work, such as cutting the incoming line and using a heavy compressor to crimp the fuse instead of just replacing the fuse.

[0005] When replacing a burnt-out fuse, the length of the service entrance line is shortened due to the reinstallation, resulting in additional costs for wiring replacement work if necessary. The problem to be solved

[0007] An embodiment of the present invention is intended to provide a wire fuse connection device that can reduce the time required for high-altitude work for fuse replacement by improving the wire fuse connection method to a bolt and nut fastening form, and can reduce construction costs for fuse replacement and the occurrence of safety accidents for workers. means of solving the problem

Referring to FIG. 1, the connecting device for a wire fuse according to an embodiment of the present invention includes a wire fuse (10) having a fuse inside a main body (12) formed in the longitudinal direction and incoming line connecting parts (14) on both sides of the main body (12), and a connecting fitting (100) having one side connected to the incoming line connecting part (14) and the other side connected to the incoming line (124). By improving the wire fuse (10) connection method to a bolt and nut fastening form, the time required for high-altitude work for fuse replacement can be shortened, and the cost of fuse replacement construction and the occurrence of safety accidents for workers can be reduced.

[0022] The connecting fitting (100) includes a first connecting part (110) and a second connecting part (120), and the connecting fitting (100) connected to the wire fuse (10) is improved to a bolt and screw fastening structure so that a worker can easily separate and assemble it. By improving the bolt and nut type connecting fitting (100) for the wire fuse, a worker can easily connect the wire fuse (10) which is installed and operated on the secondary side of a power distribution transformer to prevent damage to the wire when an excessive current exceeding the specified current occurs in the wire, and the time for working at height can be shortened by replacing the wire fuse (10), and the construction costs and the risk of safety accidents resulting from the shortening of working at height can be minimized.

[0023] The first connecting part (110) is formed as a coupling structure on both sides of the incoming line connecting part (14) and can be electrically connected to a fuse. The first connecting part (110) may include a bolt connecting part (114) in which one side is connected to the incoming line connecting part (14) with the bolt head (112) at the center, and the other side is formed as a bolt body.

[0024] The second connecting part (120) has a connection structure for an incoming line (124) on one side and can be connected to the first connecting part (110) in a separate connection structure. The second connecting part (120) may include a nut connecting part (122) that is screw-fastened to the bolt body of the bolt connecting part (114). One side of the incoming line (124) can be inserted and connected inside the nut connecting part (122). When the nut connecting part (122) is screw-fastened to each of the bolt connecting parts (114) formed in different directions at both ends of the incoming line connecting part (14) to be firmly and tightly connected, the incoming line (124) inserted into the nut connecting part (122) can be electrically connected to the wire fuse (10). The incoming line (124) can be fixed by removing the insulation covering for a preset length to expose the conductor (124a) and then connecting it to the wire fuse (10) through the connecting fitting (100).

[0025] It may further include an incoming line connecting fitting (124b) that is coupled to the end of the incoming line (124) and connected to the end of the bolt body. Here, the compressed portion of the incoming line connecting fitting (124b) and the conductor (124a) on the incoming line (124) side can be reused when replacing the wire fuse (10) after the initial installation.

[0026] As described above, the wire fuse (10) to which the connecting device for the wire fuse according to the embodiment of the present invention has a connecting fitting (100) formed in the form of a bolt and nut connection is applied, has a first connecting part (110) in the form of a bolt formed on the outer shape of the incoming line connecting part (14) at both ends of the main body part (12) of the wire fuse (10), and can apply a second connecting part (120) in the form of a rotating nut to the transformer and the incoming line connecting part for the consumer.

[0027] Meanwhile, there are six types of wire fuses (10) currently used for protecting low-voltage service entrance lines, and the rated voltage is 220V. A total of six types of connecting fittings (100) for connecting service entrance lines (124) according to wire specifications for each rated current may also be provided. 38A (2.6 mm²), 50A (3.2 mm²), 100A (22 mm²), 150A (38 mm²), 200A (60 mm²), 300A (100 mm²)

[0028] FIG. 2 is a schematic diagram illustrating a wire fuse connection device according to another embodiment of the present invention. Referring to FIG. 2, the wire fuse connection device according to another embodiment of the present invention differs from the wire fuse connection device according to an embodiment of the present invention in the shape of the connection fitting (100). While describing the wire fuse connection device according to another embodiment of the present invention, detailed descriptions of contents that overlap with the wire fuse connection device according to an embodiment of the present invention are omitted. In the wire fuse connection device according to another embodiment of the present invention, the first connection part (110a) may include a bolt connection fitting (100) (114a) formed with one side centered on the bolt head (112a) in the shape of a fuse connection fitting (100) (116) inserted inside the incoming line connection part (14), and the other side formed as a bolt body.

[0029] The incoming line connection part (14) may further include a guide part (14a) into which a fuse connection fitting (100)(116) is inserted. The guide part (14a) is formed in a hollow shape so that when the fuse connection fitting (100)(116) is inserted, it can be compressed according to an external force to maintain a connected state as a single unit. In this way, with the first connection part connected to the wire fuse (10), the second connection part (120) can be connected to the first connection part to electrically connect the incoming line (124) and the wire fuse (10).

Furthermore, construction costs and concerns regarding safety accidents can be minimized due to the reduction in working time at height. In addition, when using an insertable nut, existing wire fuses (10) can be used, and costs and time can be reduced by compressing on the ground and fastening from above.
