In order to protect the above, a protection cap 70 as shown in FIG. 10 has been conventionally proposed (JP-A-6-267600). In this protective cap 70, a plate-shaped terminal 72 is arranged in a box-shaped main body 71, and a protrusion 74 is provided in a hole 74 of the plate-shaped terminal 72 through an assembling hole 73 of the main body 71 and a counterpart terminal (not shown). By inserting the bolts 75 thus formed and screwing the bolts 75 onto the nuts 76, the counterpart terminals and the plate-like terminals 72 are electrically connected, and the main body 71 is capped with the lid 77.

There is a risk that the worker may accidentally come into contact with the bolt 75 and receive an electric shock during the screwing operation with the screw 6. Further, since the plate-like terminal 72 and the mating terminal are electrically connected to each other by screwing the bolt 75 and the nut 76, there is a drawback that the number of parts is increased. In addition, until the screwing work is performed, it is necessary to temporarily hold the bolt 75 and the nut 76 so as not to lose them, so that the efficiency of the work of connecting the plate-shaped terminal 72 and the counterpart terminal is lowered. .

2a is pressed by the washer 5a, and the flexible locking piece 22 bends in the bolt insertion direction (P direction). After insertion, the flexible locking piece 22
Since the free end portion 22a of the rail rides over the washer 5a, the flexible locking piece 22 is restored to its original state and is located above the washer 5a. As a result, the free end portion 22a of the flexible locking piece 22 prevents the washer 5a from rising. That is, the washer-equipped bolt 5 is less likely to come off, and the washer-equipped bolt 5 is temporarily fixed to the main body 10.

れる。As shown in FIG. 9, a nut member 8 is arranged below the mating terminal 7, a bolt 5 with a washer is inserted into the nut member 8 only slightly, and they are meshed with each other. In order to screw the bolt 5 with a washer onto the nut member 8, a tool (not shown) such as an impact wrench is used for the head 5b of the bolt 5 with a washer.
Even if the flexible locking piece 22 is inserted into the bolt insertion direction (P
Direction), it does not hinder the insertion of the tool. Then, the plate-shaped terminal 2 and the mating terminal 7 are electrically connected to each other through the conductive pedestal 30 by screwing the washer-equipped bolt 5 and the nut member 8 with a tool. After the connection, the small locking frame 46 of the front lid 41 and the small protrusion 26a of the main body 10 are engaged with each other, and the engaging rib 23 of the main body 10 and the side wall 43 of the front lid 41 are engaged with each other. 41 is attached to the main body 10.

る。As described above, according to the first aspect of the present invention, the peripheral wall projects from the periphery of the assembly hole formed in the bottom wall of the main body to the outside of the main body, and a plurality of locking members are provided on the inner surface of the peripheral wall. Since the claw is arranged and the locking groove is formed on the outer surface of the conductive pedestal,
The conductive pedestal is integrally assembled to the main body by the engagement of the locking claw and the locking groove. Accordingly, after the bolt is inserted into the through hole formed in the conductive pedestal, the hole of the plate-like terminal, and the assembling hole of the main body, the bolt can be screwed to the mating terminal. Therefore, it is possible to save the labor of positioning the hole of the plate-shaped terminal with respect to the bolt protruding from the counterpart terminal as in the past, and to connect the plate-shaped terminal and the counterpart terminal without damaging the counterpart terminal. Can be done safely and quickly.
