Outer cylinder, a lower projection formed on the lower surface of the outer cylinder and fitted into the lower locking hole, an upper projection formed on the upper surface of the outer cylinder, and a terminal plate transparently fitted to the upper projection. Upper locking hole, an insulating inner cylinder whose tubular portion is inserted into the through hole through the through hole of the terminal board, and a bulging portion formed on the upper portion of the inner tube and having its lower surface placed on the terminal board. And a bolt inserted into the inner cylinder and screwed into the screw hole, and external and internal lead wire connecting portions formed on the terminal plate.

[0007]

In the terminal board mounting device of the present invention constructed as described above, the lower and upper projections are formed on the lower and upper surfaces of the outer cylinder, and these are formed on the lower locking hole of the board and on the terminal board. The inner cylinder that fits into the locking hole and presses the terminal plate is inserted into the through hole of the outer cylinder, and the bolt inserted into the inner cylinder is screwed into the screw hole of the board. Can be fixed without rotating, does not require screws other than bolts, has a small number of parts, has a simple configuration, and is extremely easy to work with.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment will be described with reference to FIGS. In these drawings, the same symbols as those in FIGS. 3 and 4 indicate the same or corresponding ones. Reference numeral 17 is a screw hole formed in the substrate 1, 18 and 19 are small lower locking holes and large lower locking holes transparently provided in the substrate 1 on the left and right of the screw hole 17, and 20 is a vertical through hole 21. Formed insulating outer cylinders 22 and 23 are a small lower projection and a large lower projection formed on the left and right of the lower surface of the outer cylinder 20, respectively. Hole 1
9 is fitted. 24 and 25 are left of the upper surface of the outer cylinder 20,
The small upper projection and the large upper projection are formed on the right side and have the same shape as the small and large lower projections 22 and 23, and are formed right above.

Reference numeral 26 is a through hole formed in the terminal plate 12,
Reference numerals 7 and 28 denote small upper locking holes and large upper locking holes formed in the left and right terminal plates 12 of the through hole 26, respectively.
4 and the large upper protrusion 25. Reference numeral 29 denotes an insulating inner cylinder, and 30 denotes a cylindrical portion formed at a lower portion of the inner cylinder 29, which is fitted into the through hole 21 through the through hole 26. 31 is the inner cylinder 2
9 is a bulging portion on the upper side, and the lower surface is placed on the terminal plate 12. Reference numeral 32 is a long bolt which is inserted into the inner cylinder 29 via the washer 15 and the flat washer 16 and whose lower end is screwed into the screw hole 17 so that the board 1 is inserted through the outer cylinder 20 and the inner cylinder 29. The terminal board 12 is attached.

Reference numeral 33 denotes an external conductor connecting portion, which is a bolt 3
4 is inserted through the through hole of the terminal plate 12, the external conductor 35, the flat washer 16 and the washer 15, and is screwed into the nut 36. 37
Is the internal conductor connection, and the bolt 38 is the washer 1
5, the plain washer 16 and the internal conductor 39 are inserted and screwed to the terminal plate 12.

At the time of mounting, the lower projections 22 and 23 of the outer cylinder 20 are fitted into the lower locking holes 18 and 19 of the substrate 1 to position the outer cylinder 20, and the upper locking holes of the terminal board 12 are positioned. Two
7 and 28 are fitted to the upper protrusions 24 and 25 of the outer cylinder 20 to position the terminal plate 12 in the outer cylinder 20, the cylinder portion 30 of the inner cylinder 29 is inserted into the through hole 21, and the bolt 32 is inserted into the inner cylinder. It is inserted into 29 and screwed into the screw hole 17.

In the above embodiment, two protrusions 22, 23, 24, 25 are formed on the lower surface and the upper surface of the outer cylinder 20, but they may be formed one by one, and the board 1 and the terminal board 1 may be formed.
Even if the two locking holes 18, 19, 27, 28 are also provided one by one, the terminal plate 12 can be fixed to the substrate 1 without rotating.

[0013]

Since the present invention is constructed as described above, it has the following effects. A lower protrusion 22 and an upper protrusion 24 are formed on the lower surface and the upper surface of the outer cylinder 20, and these are fitted into the lower locking hole 18 of the substrate 1 and the upper locking hole 27 of the terminal plate 12, respectively, and the terminal plate 12 is secured. The pressed inner cylinder 29 is the outer cylinder 2
Since the bolt 32 inserted into the through hole 21 of 0 and inserted into the inner cylinder 29 is screwed into the screw hole 17 of the board 1, the terminal plate 12 can be fixed to the board 1 without rotating, and the bolt 32 No other screws are needed, the number of parts is small,
The configuration can be simplified and the work can be made extremely easy.
