Hereinafter, the use of the cap device for the power connection according to the present invention having the above-described configuration will be described in detail.

The fastening nut 37 is inserted and fixed into the nut seating space 24 of the frame 10. The internal connecting member 30 can be connected to components in the internal space formed by the frame 10 and the cover 16 to form a circuit. One side of the internal connecting member 30 is located at the seating end 22. The center of the fastening nut 37 in the nut seating space 24 of the seating end 22 coincides with the center of the through hole 32.

The hinge portion 43 of the cap 40 is coupled to the hinge axis 26, so that the cap 40 can be rotated at a predetermined angle about the hinge axis 26. While the cap 40 is rotated to open the power connection unit 20, the external connection member 35 is connected to the internal connection member 30.

That is, the external connecting member 35 is positioned on the internal connecting member 30. At this time, each through hole 32 and 36 is aligned. In this state, the fastening bolt 38 is passed through the through hole 32.36, the fastening nut 37 and the fastening bolt 38 are left in a state in which they can be combined, and the fastening bolt (38) is tightened using an electric tool. 38) is rotated so that the fastening nut 37 and the fastening bolt 38 are fastened.

In this way, the cap 40 is closed while the internal connecting member 30 and the external connecting member 35 are fastened with the fastening bolts 38. That is, the cap 40 is rotated around the hinge axis 26 to shield the fastening bolts 38 and the like with the cap body 42.

You can. If the detection piece 45 of the cap body 42 can be accurately seated in the guide groove 33 without interfering with the external connecting member 35, the external connecting member 35 and the internal connecting member 30 ) means that they are combined correctly. That is, the corresponding surface of the external connecting member 35 is accurately seated on one surface of the internal connecting member 30 in contact with each other. Accordingly, the electrical connection between the internal connection member 30 and the external connection member 35 is normal, thereby preventing abnormal heat generation.

In a state where the cap 40 shields the power connection part 20, the coupling jaw 29 of the coupling plate 28 is hooked to the end of the cap body 42 in the width direction. That is, the coupling jaws 29 of the coupling plates 28 on both sides are hung on both sides of the cap body 42, so that the cap 40 is not rotated arbitrarily and is firmly fixed to the power connection unit ( 20) so that it can be shielded.

Next, as shown in FIG. 9, the assembly of the member cover 54 and the inspection member 50 is mounted on the cap 40. The body portion 50' of the inspection member 50 protruding outside of the hanging piece 60 is passed through the bolt hole 47 of the cap 40. At this time, the hanging piece 60 also penetrates the bolt hole 47 so that the hanging shoulder 60' can be hung on the edge of the exit side of the bolt hole 47.

When the body portion 50' of the inspection member 50 enters the tool groove 39' of the fastening bolt 38, if the fastening bolt 38 is not fastened to the fastening nut 37, The head 52 of the inspection member 50 is located at a slight distance from the upper surface of the cap body 42. This is because the fastening bolt 38 does not descend further toward the fastening nut 37. Accordingly, the operator can confirm that the fastening bolt 38 is not completely fastened to the fastening nut 37.

In this case, the worker holds the head 52 of the inspection member 50, that is, the member cover 54, by hand and rotates the fastening bolt 38 so that the fastening bolt 36 is connected to the fastening nut 37. ) can be further tightened.

In this process, when the fastening bolt 38 is completely fastened to the fastening bolt 36, the lever jaw 66 formed on the locking lever 64 of the member cover 54 is attached to the cap 40. It goes over the formed protrusion (49). In this process, the locking lever 64 repeats elastic deformation and restoration, and the worker can sense this state. When this process is completed, it can be confirmed that the fastening bolt 38 has been completely fastened.

Meanwhile, through this process, the hook 60' formed on the hook piece 60 of the member cover 54 can be hung on the edge of the exit side of the bolt hole 47 of the cap body 42. . In this case, the member cover 54 is hung and fixed to the cap. Ultimately, the inspection member 50 may be fixed to the cap 30 together with the member cover 54. Of course, the hanging piece 60 on which the hanging jaw 60' is formed can be elastically deformed when an operator applies a certain amount of force, so the inspection member 50 including the member cover 54 is separated from the cap 40. It can be separated.
