DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this terminal device is an example of a feed terminal device in a temporary power distribution board, and includes a mounting rail 1, a terminal base 2, a fixing means 3, and a mounting tool 4.
And a terminal plate 5 and a terminal cover 6.

The mounting rail 1 has two rail pieces 8 raised on a base 7 with their ends directed outward in opposite directions, and is mounted on a mounting base 30 such as a distribution board. The plurality of terminal bases 2 are slidably mounted on the mounting rail 1. That is, the lower surface has a groove 9 slidably engaged with the two rail pieces 8 and is engaged with the rail piece 8. It has a side wall 11 in the width direction, a support plate 12 is provided over the insulating wall 10 and the side wall 11 above the rail piece 8, and a center plate 13 is provided between the support plates 12. Reference numeral 14 denotes a holding portion facing the center plate 13, and reference numeral 15 denotes a positioning projection.

The fixing means 3 positions and fixes both ends of the plurality of terminal bases 2. That is, a groove 16 is slidably fitted to the rail piece 8, and a fixing screw 17 provided on the upper surface is tightened and its tip is pressed onto the rail piece 8 to be fixed to the rail piece 8. Reference numeral 18 denotes a fall prevention piece. In addition, in order to arrange the insulating plate 24 on one side of the terminal unit base 2 in the direction in which the terminal walls 2 do not have the insulating wall 10, a groove 23 is formed in the insulating plate 24 so as to slidably engage the rail piece 8. I have.

A pair of fixtures 4 are attached to those located at both ends in the direction in which the plurality of terminal bases 2 are arranged, and the tips extend upwardly from the terminal bases 2. That is, a metal rectangular plate is bent into a U-shape, and the central portion thereof is
The mounting piece 22 is formed with a cutout recess 21 that engages with the positioning projection 15, and both ends that become the tip are bent outward to form a support piece 19, and a screw hole is formed in the support piece 19. 20
Is formed. Place the mounting piece 22 on the center plate 13 and the holding portion 14
The support plate 12 supports both ends of the insertion mounting piece 22 between the mounting plate 22 and the notch recess 21 is locked to the positioning projection 15. One of the pair of fixtures 4 is a pair of terminal bases 2.
Is supported by the insulating wall 10 of the terminal unit 2
0 and supported by the insulating plate 24.

The plurality of terminal plates 5 have terminal screws 25 and are attached to components other than those located at both ends of the terminal base 2. That is, the terminal plate 5 is supported by the support plate 12 and the central portion 13 and is held by the holding portion 14.
Notch recess 2 which is positioned and engaged with positioning projection 15.
6 are formed. The terminal screw 25 is located between the support plate 12 and the center plate 13. The longitudinal direction of the mounting rail 1 of each terminal plate 5 is determined by the plurality of terminal bases 2 and the insulating plate 24.

The terminal cover 6 has a driver insertion hole 28 aligned with the terminal screw 25 and is attached to the distal end of the attachment 4 by an attachment screw 27. The driver insertion hole 28 is provided in only one of the terminal screws 25, but may be provided in both. Reference numeral 29 denotes a hole through which the mounting screw 27 passes. In this embodiment, a terminal plate 5 is mounted on a plurality of terminal bases 2 and is passed through a rail piece 8 of a mounting rail 1. At this time, the insulating wall 10 of each terminal base 2 insulates between the terminal bases 2. In addition, fittings 4 are mounted on both ends of the terminal device base 2 in the arrangement direction instead of the terminal plates 5. Next, the insulating plate 24 is arranged on the one end side of the terminal block 2 on the side where the insulating wall 10 is not located, and the fixing means 3 is further arranged, and the fixing screws 17 thereof are tightened and fixed. The terminal cover 6 is mounted on the mounting metal 4 with the mounting screw 27.

According to this embodiment, the driver insertion hole 28
Through a screwdriver (not shown) to loosen the terminal screw 25,
The connection can be made without removing the terminal cover 6 from the side of the terminal cover 6. In this case, since the mounting fixture 4 for fixing the terminal cover 6 is attached to the terminal base 2, the interval between the plurality of terminal bases 2 is constant, so that the driver insertion hole 28 of the terminal cover 6 and the terminal screw 25 Easy alignment
And it can be done reliably . Furthermore, since the terminal cover 6 is fixed to the mounting rail 1 via the terminal stand 2 and the fixing means 3, the terminal cover 6 can be prevented from being displaced and can be fixed firmly. In addition, it is located at both ends of a plurality of terminal bases 2.
Are provided with mounting members 4, and these mounting members 4 are provided with terminal covers.
-6 is screwed, so the terminal cover 6 can be
Since the table 2 can be shared, the number of parts can be reduced and
By attaching the fixture 4 to the base 2,
On the other hand, the terminal cover 6 can be arranged at a predetermined height.
You.

[0013]

[Effect of the invention] terminal apparatus of this invention, because that secure the fixture to secure the pin cover the terminal unit block, and the driver insertion hole of the terminal cover because spacing between the plurality of terminals devices block is constant The positioning with the terminal screw can be easily and surely performed . Further, since the terminal cover is fixed to the mounting rail via the terminal device base and the fixing means, there is an effect that the positional displacement of the terminal cover can be prevented and the terminal cover can be firmly fixed. Also located at both ends of multiple terminal block
Attach attachments and screw the terminal cover to these attachments
The terminal block can be shared for mounting the terminal cover
Therefore, the number of parts can be reduced and
The terminal cover to the terminal block.
Can be placed at height.
