Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a terminal cover mounting device that uses fixing screws for a terminal block main body to attach a terminal cover to a terminal block.

BACKGROUND ART A terminal block main body is fixed at a predetermined location by a stud, and a terminal cover is attached to the stud.

Problems to be Solved by the Invention However, in the conventional configuration, the terminal block body and the terminal cover were attached separately, which caused the problem of poor workability.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a terminal cover mounting device that can simultaneously fix the terminal block main body and the terminal cover using the same screw.

Means for Solving the Problems In order to achieve the above object, the present invention provides a terminal block in which a mounting piece of a terminal block main body is provided with a mounting screw insertion portion that penetrates vertically, and a tube that fits into the mounting screw insertion portion. and a flange portion for pressing the base of the terminal cover mounting plate onto the upper surface of the mounting piece.

Function: By inserting a bolt or stud into the cylindrical part of the spacer and applying the nut screwed onto the head of the bolt or stud to the flange part of the spacer, the mounting piece of the terminal block body and the terminal cover can be connected. The base is fixed at the same time.

Embodiment FIG. 3 is a front view of a terminal block according to an embodiment of the present invention.

In this figure, a terminal block body 10 made of synthetic resin
There are partition walls 1 arranged in the left and right direction at the top and bottom of the
1 and 12 form a plurality of chambers 13 and 14. Inside each chamber 13, 14,
A pair of upper and lower terminal screws 20 and 21 are provided. At both left and right ends of the terminal block main body 10, a mounting piece 16 having a mounting screw insertion part (FIG. 1) 15 consisting of a round hole is provided protrudingly.
6a has a pair of front and rear seating parts (Fig. 2) 17a, 1
7b, and locking portions (hereinafter referred to as recesses) 18a and 18b consisting of blind holes. Each of the upper and lower terminal screws 20 and 21 is covered with a terminal cover 3 made of synthetic resin.
0 and 40, and both left and right ends of each terminal cover 30 and 4 are attached to the terminal block main body 10 by a pair of terminal cover attachment plates 50 and 60 made of thin metal plates, respectively.

FIGS. 1 and 2 are cross-sectional views showing details of the terminal cover mounting portion. As shown in FIGS. 6 and 7, the terminal cover mounting plates 50 and 60 have base parts 51 and 61 formed by bending one end, and a holding part 5 formed by bending the other end.
2, 62, and the base portions 51, 61 are provided with mounting screw insertion portions (round holes in the figure) 53, 63 corresponding to the mounting screw insertion portion 15. Further, as shown in FIG. 2, on both sides of the base 61 of the terminal cover mounting plate 60 on the lower side, there are latches that fit and lock into the recesses 8a and 18b of the mounting piece 16 at the tip bent in a dogleg shape. Portions 64a and 64b are integrally formed.

In addition, in FIGS. 1 and 2, reference numeral 70 denotes a spacer made of synthetic resin, which passes through the mounting screw insertion portion 53 of the terminal cover mounting plate 50 on the upper side and attaches to the terminal block main body 10.
The mounting piece 16 is inserted through the cylindrical part 71 having an outer periphery that can be fitted into the mounting screw insertion part 15 with a slight press fit, and the base part 51 of the terminal cover mounting plate 50 on the upper side.
The flange portion 72 is arranged on the upper surface portion 16b of the flange portion 72. 80 is a bolt as a mounting screw.

As shown in FIG. 8, positioning recesses 31, 41 are provided at both ends of the terminal covers 30, 40.

Next, a method for attaching the terminal covers 30, 40 will be explained.

First, after inserting the cylindrical part 71 of the spacer 70 into the mounting screw insertion part 53 of the terminal cover mounting plate 50 on the upper side,
Fit the cylindrical part 71 into the mounting screw insertion part 15 of the terminal block main body 10 so that the holding part 52 is located on the endmost partition wall 11, and attach the base part 51 of the terminal cover mounting plate 50 to the mounting piece using the flange part 72. 16 upper surface part 16
Assign it to b. In this case, since the cylindrical portion 71 is fitted into the mounting screw insertion portion 15 with a slight press fit,
After that, when installing the lower terminal cover mounting plate 60, even if the terminal block main body 10 is turned over, the spacer 70
And the terminal cover mounting plate 50 will not fall off.

Thus, when attaching the lower terminal cover 60, the locking portions 64a, 64b are fitted into the recesses 18a, 18b of the attachment piece 16. At this time, the bent ends of the locking parts 64a and 64b elastically abut and lock against the side surfaces of the recesses 18a and 18b, that is, by gripping between the recesses 18a and 18b, The base portion 61 of the terminal cover mounting plate 60 is so-called temporarily fixed to the mounting piece 16 of the terminal block main body 10. Therefore, after that, the terminal block body 1
Even if the terminal cover mounting plate 60 is oriented so that the terminal cover mounting plate 60 protrudes downward, the terminal cover mounting plate 60 will not fall off.

Next, after placing the seating portions 17a and 17b of the mounting piece 16 on a fixing base 90 such as a placement board, the bolts 80
The male threaded portion 80b is inserted into the cylindrical portion 71 of the spacer 70 and screwed onto the fixing base 90. In this case, bolt 80
The head 80a of the spacer 70 acts on the flange 72 of the spacer 70, and the base 51 of the terminal cover mounting plate 50 on the upper side
is on the top surface 16b of the mounting piece 16, and the mounting piece 16
The lower surface portions 16a of the lower surface portions 16a are pressed and fixed to the fixing base 90, and at the base 61 of the lower terminal cover mounting plate 60, the engaging portions 64a, 64b are connected to the upper surface of the recesses 18a, 18b and the upper surface of the fixing base 90. It is held in a fixed state by being sandwiched between the

Install the four terminal cover mounting plates 5 as described above.
0, 50, 60, and 60 are attached to the terminal block body 10 at the same time as the terminal block body 10 is fixed. And the terminal cover mounting plates 50 on the upper left and right (Fig. 3),
The recesses 31, 31 of the upper terminal cover 30 are hooked onto the holding parts 52, 50 of the terminal cover 50, so that the terminal cover 30 is held astride the upper partition walls 11. In addition, on the holding parts 62, 62 of the terminal cover mounting plates 60, 60 on the lower left and right sides (Fig. 3),
The recesses 41, 41 of the terminal cover 40 on the lower side are attached and held in the same manner as described above.

Note that the terminal covers 30 and 40 may be attached prior to attaching the terminal block main body 10 to the fixing base 90.

Further, as an alternative to the bolt 80 of the embodiment, a combination of a stud and a nut can be used. Further, in the embodiment, the terminal cover mounting plates 50 and 60 are provided on both the upper and lower sides, but it is obvious that only the upper terminal cover mounting plate 50 can be provided and used.

Effects of the invention According to the terminal cover mounting device for a terminal block of the present invention, when installing the terminal cover mounting plate, the base of the terminal cover mounting plate is positioned in the mounting screw insertion portion of the terminal block body using the spacer, and the base of the terminal cover mounting plate is This has the effect that the mounting piece of the terminal block body and the mounting piece of the terminal block body can be fixed at the same time with the same screw, and workability can be improved.
