DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for attaching a structure such as a terminal block to a support having a horizontally projecting piece projecting outward.

[0002]

2. Description of the Related Art Conventionally, terminal blocks have been mounted on top hat-shaped rails, C-shaped rails, and G-shaped rails, each of which has a groove-like shape and horizontally projecting pieces project outward from upper ends on both sides thereof.
Alternatively, the terminal block may be directly attached to the panel. A fixture separate from the terminal block is used to attach the terminal block to the rail.

[0003] An elastic member is mounted on a terminal block and can be attached to and detached from the rail with one touch.

[0004]

The terminal block and the fixture of the separated type have a large number of component parts, and since the terminal block and the fixture are separated, the fixture may be lost. In addition, since the one-touch fixing device uses an elastic member, there is a concern about mechanical strength when fixing a heavy object.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention does not separate a fixture such as a terminal block to be mounted from a fixture, and has a small number of components, and is easy and reliable. A fixture that attaches a structure to a support that has a horizontally projecting piece projecting outward so that the oblique piece extends from one end of the base piece and is bent inward at the tip of the oblique piece. A fixing plate, which is formed with a hooked piece, and has a thread engraved on the base piece, a plane contacting the base piece of the fixing plate, a slope abutting on the oblique piece, and opposing each other with a plate thickness of the fixing plate. A guide surface, a holding groove for one of the horizontally projecting pieces of the support, and a through-hole at a location facing the thread of the fixing plate, and inserted into the through-hole and screwed into the thread. Mounting groove on one horizontal protruding piece of the support, and a holding groove on the other horizontal protruding piece. Multiplying pieces were engaged respectively, and the fixture was set to secure the structure to the support by screwing mounting screws.

Further, in the present invention, in order to ensure that the fixture does not separate from the structure, a mounting screw without an intermediate thread is used.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. Although the structure is not limited to the terminal block, the terminal block will be described here as an example.
Here, a long rail 1 will be described as an example of the support. The rail 1 is an extruded aluminum member having a groove shape and horizontally projecting pieces 2 and 3 projecting outward from the upper end thereof. The rail 1 is attached to an operation panel or the like by using an end groove 20.

Although there are various types of structures, the terminal block 4 will be described here as an example. The fixing plate 5 is made of a sheet metal having a narrow width, and has a slant 7 extending from one end of the base 6, and a hook 8 bent inward at the tip of the slant 7. 9 is engraved.

The terminal block 4 is made of a synthetic resin and has the following configuration for mounting the fixing plate 5 and the mounting screws 10.
A flat surface 11 in contact with the base piece 6 of the fixed plate 5, a slope 12 in contact with the oblique piece 7, a guide surface 13 provided to face the fixed plate 5, separated by a plate thickness t, and one horizontal surface of the rail 1. As shown in FIG. 3, an oval long hole-shaped insertion hole 15 is formed at a position facing the holding groove 14 of the projecting piece 2 and the screw thread 9 of the fixing plate 5. As long as the insertion hole 15 is a long hole, the end may not be circular but may be linear.

The mounting screw 10 is inserted into the insertion hole and screwed to the thread 9 of the base piece 6. Terminal block 4 and mounting screws 10
A seat plate 21, a flat washer 22 and a spring washer 23 are interposed between the head plate and the head. Next, the fixing of the terminal block 4 to the rail 1 will be described. First, when the mounting screw 10 is loosened, the fixing plate 5 is
3 and moves diagonally downward. At the same time, the mounting screw 10 also moves through the insertion hole 15 in the horizontal direction. The fixing plate 6 is moved in the horizontal direction by the elongated insertion hole 15 and the oblique groove by the vertical movement of the mounting screw 10. When the fixing plate 5 moves obliquely downward, the terminal block 4 and the fixing plate 5 are moved.
Is larger than the width of the rail 1. Therefore, the rail 1 is connected to the horizontally projecting piece 2 by the holding groove 1 of the terminal block 4.
4 and a fixing plate 5
Are engaged with each other. Thereafter, when the mounting screw is closed, the fixed plate 5 moves obliquely upward, the rail 1 is sandwiched between the terminal block 4 and the fixed plate 5, and the terminal block 4 is
Fixed to.

A screw thread is eliminated in the middle of the shaft of the mounting screw 10 shown in FIG. When the mounting screw 10 is loosened to reach a portion having no screw thread, the screw thread 10 rotates in an empty manner, so it is understood that the screw thread 10 has reached a portion having no screw thread, and no further attempt is made to loosen the screw. Therefore, the fixing plate 5 is not separated from the terminal block 4, and the fixing plate 5 is not likely to be lost.

Although a terminal block has been described as an example of a structure, the present invention is not limited to a terminal block.
Although the rail has been described as a support, it is not so limited.

[0013]

As described above, the present invention relates to a fixture for mounting a structure on a support having a horizontally projecting piece projecting outward, wherein the oblique piece extends from one end of a base piece. A fixing plate comprising a hook piece bent inward at the tip of the fixing plate, and a thread engraved on the base piece, a plane contacting the base piece of the fixing plate, a slope contacting the oblique piece, and a plate of the fixing plate. A structure having a guide surface provided oppositely with a thickness, a holding groove of one of the horizontally projecting pieces of the support, and an insertion hole at a position opposed to the screw thread of the fixing plate, and inserted into the insertion hole. A mounting screw threadedly engaged with a screw thread, a holding groove is engaged with one horizontal projecting piece of the support, and a hook piece is engaged with the other horizontal projecting piece, and the mounting screw is screwed in to attach the structure to the support. Since the fixture is designed to be fixed, the fixture is not separated from the structure such as the terminal block to be attached. Fear of losing the fixing plate also becomes nil.

Further, according to the present invention, the number of components of the fixture is reduced, and the fixture can be provided at low cost. Further, according to the present invention, the structure can be easily and reliably attached to and detached from the support. Further, according to the present invention, since the intermediate screw thread of the mounting screw is eliminated, the fixing plate does not separate from the structure without fail, and the fixing plate is not likely to be lost.
