Description

[Detailed Description of the Invention] This invention relates to a terminal device such as a feed-in for a wiring duct.

The feed-in that forms the basis of this idea is shown in Figures 1 to 4.
Shown in the figure.

That is, in this feed-in, the terminal block 2 is fixed to the base 1, the rear end portions of the pair of terminals 3, 3' are attached to the terminal block 2, and terminal screws 4, 4' are provided.

The terminal block 2 has a cover mounting opening 5 above the terminal screw 4.4'.
A recess 6 is formed at the edge thereof, and a tapered projection 7 is formed in the recess 6.

The cover 8 has an L-shaped bent shape and has a thin section 9a at one end.
A hinge tongue piece 9 with a hinge portion formed by the recess 6 is provided.
A long engagement hole 10 is formed in the hinge tongue piece 9, and the protrusion 7 is fitted into the hinge tongue piece 9.

Furthermore, a cap 11 is provided to cover the tips of the terminals 3, 3' for positioning when attached to the end of the wiring duct 12, and the plug blades 3a of the terminals 3, 3' are made to protrude from both sides of the cap 11. A protrusion protrudes from the engagement hole 10 by forming an engagement hole 14 and a horizontal groove 16 into which the tip of the hinge tongue piece 9 is inserted at the opening edge of the cap 11 so as to be brought into pressure contact with the conductor 12a of the wiring duct 12. 7 by using the taper 7a and attaching it to the base 1 with screws 13.

Open the cover 8 and connect the power wire (not shown) to the terminal screws 4, 4.
', then remove the knockout part 8a of the cover 8, close it, and screw the set screw 15 into the screw hole 15 of the base 1.
Fix it to a.

15' is a cover support part, and 15' is an insertion hole for the screw 15.

3 and 4 show the opening/closing operation of the cover 8,
FIG. 3 shows the cover 8 in a closed state.

At this time, the cover 8 has a long engagement hole 17 and a horizontal groove 1.
6 so that the edge of the cover 8 comes into contact with the opening edge 11 a of the cap 11 and the cover mounting opening 5 of the terminal block 2 without creating a gap, and in this state, tighten the setscrew 15
It can be stopped.

On the other hand, FIG. 4 shows the set screw 15 with the cover 8 open.
Remove the cover 8 by the length of the elongated hole and remove the hinge tongue piece 9.
The thin wall part 9a of the cap 11 is prevented from being obstructed by the opening edge 11a of the cap 11, and the cover 8 is made easy to open.

According to this field-in, since the cover 8 is hinged to the terminal block 2, there is no fear of the cover 8 falling off when connecting the power line to the terminal, and since the hinge tongue piece 9 is slidably attached, it does not fit into the cover mounting opening 5. This has the advantage of not creating any gaps.

However, the above feed-in is
When the cover 8 is rotated open and closed, the cover 8 rotates around the thin wall portion 9a, so when the cover 8 is fixed with the set screw 15, if the set screw 15 is not inserted after the cover 8 is closed, it will not fit into the mounting hole 15''. It cannot be passed through, and when opening the cover 8, it is necessary to remove the setscrew 15 and then open the cover 8, which is a hassle and reduces work efficiency.

Furthermore, since the set screw 15 must be separated from the cover 8, there is a possibility that it may be lost.

Therefore, an object of this invention is to provide a terminal device that improves the efficiency of cover opening/closing operations.

An embodiment of this invention is shown in FIGS. 5 and 6.

That is, in this terminal device, instead of the screw mounting hole 15'' provided in the cover support portion 15 of the terminal block 2 in the terminal device shown in FIGS. 1 to 4, a set screw 15 is attached to the cover 8 to open and close the cover 8. At this time, a notch 18 is formed with an opening in a direction escaping the rotation locus of the set screw 15.

With this configuration, the through hole 1 formed in the base 1
By unscrewing the setscrew 15 from 9, it can be opened immediately as shown in FIG.

Further, when closing the cover 8, by closing the cover 8 with the screw inserted into the cover 8, the screw tip is immediately located above the tapped hole 19, so that tightening is facilitated.

In this case, if the screw is fixed in the screw insertion hole 8a formed in the cover 8 by leaving a molded burr, for example, to prevent it from coming loose, the screw 15 will fall out and be lost when the cover 8 is opened and closed. As mentioned above, in the terminal device of this invention, a notch is formed in the cover support part to escape the rotation trajectory of the set screw, and a screw hole is formed in the bottom of the notch, which improves the efficiency of cover opening and closing operations. This has the effect of improving the
