Description

[Detailed description of the invention] [Industrial application field] This invention relates to a mounting bracket for a case of a switch or the like.

[Prior art and its problems] Conventionally, this type of mounting bracket has been constructed as shown in FIGS. 4 to 7. The mounting portion of the case 1 is constructed as shown in FIG. That is, a recess 2 is provided in the mounting portion of the case 1, and the DIN rail 15 is inserted into the recess 2.
The end 17 of the DIN rail 15 is attached to one end of the case 1.
A support portion 3 is provided so as to be sandwiched between the recess 2 and the support portion 3 . A guide portion 4 is provided at the other end of the case 1, and a stopper 5 is fitted into the guide portion 4. The stopper 5 consists of an engaging part 6, a spring part 7, and an operating part 8. A projection (not shown) is provided at the center of the spring part 7, and this projection is provided on the case 1. It is fitted into a hole (not shown). The stopper 5 is configured to move back and forth along the guide of the guide portion 4 using the deflection of the spring portion 7 around this projection. The DIN rail 15 is fixed to the mounted member by tightening screws and nuts into the mounting holes of the mounted member (not shown) and the mounting holes 16 of the DIN rail 15. Next, support part 3 and recess 2 of case 1
When the end 17 of the DIN rail 15 is sandwiched between the two, and the case 1 is further pressed in the direction of the DIN rail 15, the inclined part of the engaging part 6 of the stopper 5 will be inserted into the other DIN rail 15. The end portion 17 will be pressed. Then, the stopper 5 retreats along the guide of the guide part 4 due to the deflection of the spring part 7, and
Sandwich the end 17 of the DIN rail 15 between the engaging part 6 of the stopper 5 and the recess 2 of the case 1, and then
It can be fixed to the DIN rail 15. The state at this time is shown in FIG. Also, case 1
When removing the stopper 5 from the DIN rail 15, pull the operating part 8 of the stopper 5 in the opposite direction to the direction in which it is attached to the DIN rail 15, the spring part 7 of the operating part 8 will stretch, and the engaging part 6 will be attached to the operating part 8. is moved in the tensile direction, the engaging portion 6 is disengaged from the end 17 of the DIN rail 15, and the case 1 can be removed from the DIN rail 15. DIN rail 15 is generally used when multiple cases 1 are installed.

Next, the case where one case 1 or a small number of cases 1 are attached will be explained. When installing one case 1 or a small number of cases, the DIN rail 15 is too long and takes up space. So, according to the width of case 1
When trying to cut the DIN rail, the mounting hole 16
You end up having to use the space in between. If one case 1 is mounted using the mounting hole 16, the length of the DIN rail 15 will greatly exceed the width of the case 1, resulting in wasted mounting space.

Therefore, when one case 1 or a small number of cases 1 are to be installed, the cases 1 are usually installed using the L-shaped fittings 18. The case 1 is provided with a through hole 9 on its side, and when installing, pass the screw 19 through the elongated hole 20 of the L-shaped fitting 18 and the through hole 9 of the case 1, and then tighten the nut (not shown) from the back side of the case 1. Attach to screw 19, tighten screw 19, and connect case 1 and L-shaped bracket 1.
8 and fixed. After that, in order to attach it to a predetermined location, pass the screw 29 through the other elongated hole 30 and the mounting hole of the attached member, attach the nut to the screw 29 from the attached member side, tighten the screw 29, and then tighten the L-shaped bracket 1.
8 is fixed to the member to be attached. However, L-shaped fitting 18
Compared to installing one case 1 using the DIN rail 15, the number of screws to be tightened increases from two to four locations, which increases the amount of installation work and requires new installation and installation. There is a problem that maintenance work increases and takes time.

In addition, in the installation space, L-shaped bracket 1
No. 8 requires an extra space for the area of attachment to the member to be attached, which makes it impossible to attach a plurality of pieces in close contact with each other, and there are also problems that it is impossible to attach them in a small space.

Also, when cutting the DIN rail 15 to fit the width of case 1 and installing one case 1, the space between the mounting holes 16 must be used, so use the mounting holes 16 to install one case 1. When installed, the length of the DIN rail 15 greatly exceeds the width of the case 1, resulting in a problem in that installation space is wasted.

In addition, since DIN rails are originally made so that the case can slide on the rail, the case may be affected by external vibrations, etc.
There is a problem in that the case may shift on the rail in the direction of the short side, and if the DIN rail is cut as described above, the case may fall off the DIN rail, that is, the mounting bracket.

[Purpose of the invention] The invention of the present application was made in view of the above-mentioned points, and even when only one case is installed, the installation method is easy, and at the same time, the case does not shift from the mounting bracket, and the case can only be inserted. The purpose is to provide mounting brackets that allow the case to be mounted if there is space for the case.

[Configuration and Effects] In order to achieve the above-mentioned purpose, the present invention has the following features:
A mounting bracket for a case equipped with a mounting structure compatible with a DIN rail, which includes a base part whose short side width is less than the width of the case, and both ends of the long side of the base part. an upright wall provided on each of the sections; a protrusion provided on each of the upright walls and protruding toward the outside of the base;
A protrusion provided on each of the protrusions and engaged with the case, and a protrusion provided on the base portion, one having a longitudinal direction between the protrusions and the other having a longitudinal direction in a direction perpendicular thereto. This is a mounting bracket with a long hole.

With the above-mentioned configuration, the present invention provides the upright wall with a protrusion that protrudes outward from the base, and supports the protrusion between the supporting part or engaging part of the case and the recess, so that the DIN rail You can install and remove mounting brackets with the same ease.

In addition, since the base part has a width dimension on the short side of the mounting bracket that is smaller than the width of the case, and mounting holes are provided in the base part on the inside of both edges of the protrusion, the long side of the mounting bracket Achieved smaller side width dimensions,
If there is enough space for the case, the case can be attached, and multiple cases can be attached closely together.

Since the protrusion is provided with a protrusion that engages with the case, an excellent effect is achieved in that the case does not easily shift from the mounting bracket.
