DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting tool used for mounting a component on a component mounting rail.

[0002]

2. Description of the Related Art Heretofore, a component mounting rail called a DIN rail has been widely used as a support for mounting a component such as a solenoid valve on a support surface such as a wall. D
As shown in FIG. 6, the IN rail 31 is formed by opposing substantially L-shaped protrusions 33 on one side surface of a long rail main body 32 on both sides thereof. The DIN rail 31 is used in a state where the non-projecting surface side of the projecting piece 33 is fixed to the wall side.

FIG. 1 shows a component mounting tool 35 used when mounting a component 34 on a DIN rail 31. The component mounting member 35 is made of a metal material, and a pair of holding pieces 37 for holding the protruding piece 33 protrude from both ends of the component mounting portion 36. Further, a screw hole 39 through which the screw 38 is inserted is provided in the component mounting portion 36.

[0004] Such a component fitting 35 is used, for example, as follows. 1) A screw 38 is inserted from the front side into a screw insertion hole 40 formed so as to penetrate the upper and lower surfaces of the component 34, and the tip of the projecting screw 38 is disposed on the rear side of the component 34. Screw hole 3
9 through. 2) Using the two holding pieces 37 of the component mounting tool 35 in a state where the component 34 is mounted on the component mounting portion 36,
By fitting the component fixture 35 to the IN rail 31,
The part 34 is temporarily fixed to the DIN rail 31. 3) After positioning left and right on the DIN rail 31, the screw 38
Is completely tightened, and the tip of the screw 38 is connected to DI
Screw it into the rail body 32 of the N-rail 31. As a result, the component 34 becomes immovable, and the fixing is completed. Note that the component mounting tool 35 may be temporarily fixed to the DIN rail 31 first, and then the component 34 may be screwed to the component mounting tool 35.

[0005]

However, the conventional component mounting device 35 has several problems as follows. First, even if an attempt is made to fix the component 34 only by the clamping force of the component mounting tool 35 without screwing the tip of the screw 38 into the DIN rail 31, a positional shift occurs in the left-right direction. This is because the holding force of the holding piece 37 is insufficient and the DIN rail 31 itself has a dimensional tolerance.

Second, the tip of the screw 38 is connected to the DIN rail 3
As a measure for fixing the component 34 without being screwed into the component 1, for example, end blocks may be arranged on both sides of the component 34 to thereby fix the component 34 from the side. However, in this case, there arises a problem that the whole becomes larger by the size of the end block.

Third, the tip of the screw 38 is connected to the DIN rail 3
The screw 38 may not be too long or too short in order to allow the screw 1 to be appropriately screwed and to fix the component 34 to the component mounting member 35 without looseness. Therefore, conventionally, the designation of the length of the screw 38 becomes strict. Also, screw 3
8 must also have a pointed shape, and the specification of the shape becomes strict.

[0008] Fourth, when the tip of the screw 38 is screwed into the DIN rail 31, the DIN rail 31 is damaged and the aesthetic appearance deteriorates. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a component that can securely and compactly mount a component to a rail without screwing a screw tip into a component mounting rail. It is to provide a fixture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a component mounting tool for a DIN rail will be described in detail with reference to FIGS.

FIG. 1 shows a pressure switch 1 as a component,
A DIN rail 2 as a component mounting rail, a component mounting tool 3 and a screw 4 used when mounting the pressure switch 1 on the DIN rail 2 are shown.

In this embodiment, the pressure switch 1 is a rectangular part comprising a pressure switch main body 5 and an auxiliary block 6, and a screw insertion hole 7 is formed in the auxiliary block 6 so as to penetrate the lower surface of the upper surface. Have been. An accommodation recess 8 for accommodating the head of the screw 4 is formed in the upper opening of the screw insertion hole 7.

The DIN rail 2 is a long rail body 9.
Is an aluminum member having substantially L-shaped protruding pieces 10 formed on both sides thereof on opposite sides thereof. This DIN
The rail 2 is used in a state where the non-projecting surface side of the projecting piece 10 is fixed to the side of a wall or the like which is a supporting surface.

As shown in FIGS. 1 and 2, the component fixture 3 of the present embodiment is made of a metal plate having a thickness of about 0.5 mm (for example, a cold-rolled steel plate carburized and quenched). ,
It has suitable elasticity as a whole. In addition, an iron alloy plate material other than the above-mentioned steel plate (for example, a spring steel subjected to a rust-proof treatment, stainless steel, or the like) may be used, and further, a plate material made of a copper alloy, an aluminum alloy, or the like may be used. Good. However, when the DIN rail 2 is made of aluminum, it is preferable to select a harder metal plate material for improving the prevention of displacement. That is, DI
This is because even if the claw portions 12a and 12b, which will be described later, bite into the N rail 2, wear and deformation are less likely to occur on the claw portions 12a and 12b.

At a position eccentric from the rail center line in the component mounting portion 14, two screw holes 15 through which the screw 4 can be inserted are provided.
Are formed close to each other. However, screw hole 15 is 1
Or three or more. The tip of the screw 4 is screwed into these screw holes 15. The component mounting portion 14 has a bent portion W1. Since the bent portion W1 is bent along the rail center line and in the direction opposite to the pressure switch 1, the component mounting portion 14 can be elastically deformed when the pressure switch 1 is screwed.

At both ends of the component mounting portion 14, a pair of holding pieces 12, 13 for holding the projecting piece 10 are provided in a protruding manner. The second holding piece 13, which is located relatively far from the position where the screw hole 15 is formed, is formed to bend in a substantially S-shape and has a rectangular tool insertion hole 16. on the other hand,
The first holding piece 12 located relatively close to the position where the screw hole 15 is formed is formed smaller than the second holding piece 13. The inner surfaces of the sandwiching pieces 12 and 13 are portions that come into contact with the protruding pieces 10 of the DIN rail 2 when components are mounted. Two claw portions 12a and 12b are provided at both edges of the first holding piece 12 so as to be bent in the direction of the inner surface. These claws 12a, 12b are DIN based on the overall elastic deformation of the component fixture 3 caused by screwing.
The projecting pieces 10 of the rail 2 bite each. Here, “penetration” is one mode of “pressure contact”, in other words, it is defined as pressure contact with a mating member in a form involving deformation of the mating member. The claws 12a and 12b as described above can be obtained by, for example, press working so as to sandwich both edges of the holding piece 12 with a jig. Of course, other conventionally known processing methods can be used.

Next, a method of using the component mounting tool 3 will be described. First, screw 4 is inserted into screw insertion hole 7 formed through pressure switch 1 from the front side.
This is inserted. At the same time, the tip of each projecting screw 4 is inserted into each screw hole 15 of the component fixture 3 arranged on the rear side of the pressure switch 1. Next, the component mounting tool 3 is fitted to the DIN rail 2 by using the both holding pieces 12 and 13 of the component mounting tool 3 in a state where the pressure switch 1 is mounted on the component mounting unit 14. As a result, as shown in FIG. 3, the component attachment 3 is temporarily fixed to the DIN rail 2. At this time, the bending of the component mounting part 3 in the component mounting part 14 still remains, and the component mounting part 14 and the pressure switch 1 are in a non-contact state. Therefore, the component attachment 3 hardly undergoes elastic deformation.

After the left and right positioning of the component fitting 3 and the pressure switch 1 on the DIN rail 2, the screw 4 is then completely tightened. Since the screw 4 of the present embodiment is not as long as the conventional screw, the tip of the screw 4 is not screwed into the rail body 9 of the DIN rail 2 even in a completely tightened state.

When the screw 4 is completely tightened as described above, elastic deformation is generated in the component mounting portion 14 so as to eliminate the bending as shown in FIG. 4, and the component mounting portion 14 and the pressure switch 1 are connected. It will be in close contact. Then, based on the elastic deformation, the claw portions 12a and 12b bite into the protruding piece 10 which is the contact portion with the DIN rail 2. As a result, the pressure switch 1 cannot move on the DIN rail 2, and the fixing is completed.

Of course, first, the component mounting fixture 3 is attached to the DIN rail 2.
, The pressure switch 1 may be screwed to the component attachment 3. In this case, since the component mounting member 3 made of a metal material of the present embodiment has a suitable elasticity, the holding members 12 and 13 are pressed against the DIN rail 2 to expand the both members 12 and 13. Installation can be performed easily. At this time, the second holding piece 13 particularly contributes.

It can be installed without shifting. Therefore, the pressure switch 1 can be securely mounted on the DIN rail 2. Further, according to this configuration, it is not necessary to screw the tip of the screw 4 into the rail main body 9, so that the designation of the length and shape of the screw 4 is relaxed,
In addition, deterioration of the appearance of the DIN rail 2 is also avoided. Of course, since it is not necessary to use an end block, the overall size can be reduced.

(2) With the configuration of the component mounting member 3, the deformation can be extremely easily generated by screwing, and the shape can be restored by loosening the screw 4. Therefore, the position of the pressure switch 1 can be easily changed even after the mounting is completed, and the pressure switch 1 can be used many times.

(3) In this component mounting device 3, when the holding pieces 12 and 13 at both ends hold the both protruding pieces 10 of the DIN rail 2, both the claw portions 1 provided on the first holding piece 12 are provided.
The protrusions 2a and 12b bite into the projection 10.
Therefore, not only the positioning action based on the elasticity of the two holding pieces 12 and 13 but also the positioning action by the biting of the claw portions 12a and 12b can be obtained, so that reliable positioning can be achieved.

(4) In the component fixture 3 of the present embodiment, the holding piece 1 on the side susceptible to elastic deformation due to screwing.
2, that is, the claw portions 12a and 12b are provided on the first holding piece 12. For this reason, a strong biting force can be obtained,
More reliable positioning can be achieved.

(5) In the component mounting device 3, the claw portions 12a and 12b are separated from each other by one holding piece 12.
Since it is formed at the location, it is possible to more reliably prevent the displacement as compared with the case where only one is provided.

(6) Further, the second holding piece 13 of the component attachment 3 has a tool insertion hole 16. For this reason,
At the time of removing the component attachment 3, the tip of a tool such as a flathead screwdriver or the like is inserted into the tool insertion hole 16, and the component attachment 3 can be removed according to the principle of leverage. Therefore, there is an advantage that the removal operation becomes easy.

(7) The component mounting device 3 has an advantage that it can be used even if it is turned upside down. (8) In the present embodiment in which the metal component mounting member 3 is used, the claw portions 12a and 12b can be surely cut into the aluminum DIN rail 2 without causing abrasion or deformation. And reliable positioning can be achieved.

The present invention can be modified, for example, as follows. (1) A plurality of claws 22 may be provided on the second holding piece 13 as in the case of the component mounting tool 21 of another example 1 shown in FIG. With this configuration, the holding pieces 12, 13 are DIN
When the two protruding pieces 10 of the rail 2 are clamped, the four claw portions 12
The a, 12b, and 22 cut into each other, so that more reliable positioning can be achieved.

(2) The screw holes 15 may be arranged along the center line of the rail without eccentricity, as in the case of the component mounting member 26 of another example 2 shown in FIG. 5B. (3) The number of the claws 12a, 12b, 22 is reduced to one holding piece 1.
It is also permissible to use one or two or three or more. Further, the positions of the claws 12a, 12b, 22 formed on the holding pieces 12, 13 can be changed to some extent.

(4) It is not always necessary for the component mounting tool to include the two holding pieces 12 and 13. That is, a configuration having only one holding piece 12 or 13 or a configuration having no holding piece at all is permissible, and a configuration in which the claw portions 12a, 12b, and 22 bite by deformation based on screwing or the like is sufficient. In the embodiment and other examples, the screw hole 15 is used.
However, even if there is only one, a desired biting force can be obtained, and there is no particular problem.

(5) The component mounting member is not limited to the elastically deformable metal material as in the above embodiment and the first and second alternatives. For example, similarly, the elastically deformable resin material is used. It may be. The component attachment made of a resin material is inferior to a metal material in terms of strength, but has the advantages that it is lightweight, easy to mold, and does not require rust prevention treatment. In addition, since the molding can be performed with the pigment mixed therein, there is an advantage that coloring of the component attachment is extremely easy.

(6) For example, a component mounting fixture is formed using a thermosetting resin or the like, and is heated or the like at the time of component mounting to cause hardening deformation, thereby causing the claw portions 12a, 12b
