Description

  The present invention relates to various devices that can be attached with screws in a control panel or the like, for example, devices such as an input / output terminal used in a wiring-saving system constituted by a network.

As a wiring-saving system, a programmable controller and a plurality of input terminals or output terminals are connected via branch connectors, and input devices such as limit switches and various sensors are connected to each input terminal. Alternatively, output devices such as air valves and actuators are connected to each output terminal. The programmable controller and the input terminal or output terminal are connected by a cable including a power line, a signal line, and a shield line. The input terminal takes in a signal from an input device and is programmable controller. On the other hand, the output terminal is configured to output a signal from the programmable controller to an output device (see, for example, Patent Document 1).
JP 2000-138682 A

  Equipment such as input / output terminals used in the above system is a small device having a vertical and horizontal dimension of about several centimeters, and is fixed by screwing to a support frame or the like provided in the control panel.

  In general, in small devices that can be mounted with screws, a plurality of mounting projections with mounting holes for screw insertion are integrally projected from appropriate locations on the outer periphery of the device body, but the position of the mounting holes is fixed. For this reason, the degree of freedom of attachment to the support frame or the like tends to be low.

  For example, as shown in FIG. 11, a pair of mounting projections 32a and 32b having mounting holes 31a and 31b for fixing screws are provided on the left and right sides of the device 30. As shown in FIG. The mounting protrusions 32a and 32b are shifted up and down left and right so that the gap between them can be as close as possible when the devices 30 are arranged side by side, but the mounting protrusions 32a and 32b are still adjacent to each other. It becomes an obstacle to narrow the interval between the devices 30 to be operated, and the devices 30 can not be installed at a high density in a limited installation area.

  In addition, since the mounting protrusions 32a and 32b are shifted up and down on the left and right, for example, when mounting to a support frame extending in the left and right direction with screws, when the vertical width of the support frame is narrow, the left and right mounting protrusions 32a and 32b It is difficult to align 32b with a support frame having a narrow width, or when processing a pilot hole (tap hole) of a screw in the support frame, the attachment holes 31a and 31b are vertically moved left and right. Since they are displaced, the lower holes must also be formed at positions shifted vertically on the left and right in correspondence with the mounting holes 31a and 31b, and there is a problem that the processing work is troublesome.

  Furthermore, when the device 30 is not attached with a screw but is installed using a tightening band, the attachment protrusions 32a and 32b are obstructive.

  Of course, by providing products with specifications that have different mounting protrusion mounting positions or specifications that do not have mounting protrusions, you can deal with the above problems by using different mounting specifications that match the equipment installation conditions. However, it is not only a cause of high costs to produce devices with multiple specifications that differ only in the installation specifications, but there are also problems in terms of product packaging, transportation, storage, and the like.

  The present invention has been made in view of such circumstances, and has as its main purpose to easily change the installation specifications of equipment at the installation site so that it can be installed according to the installation conditions. It is.

(1) The device of the present invention includes a mounting bracket having a mounting hole for screw insertion, and a device main body to which the mounting bracket is mounted, and the mounting bracket has a pair of mounting holes at both ends thereof. In addition, the both end portions protrude from the outer peripheral facing portion of the device main body in a state of being mounted on the device main body, and the device main body is orthogonal to allow the mounting bracket to be inserted and attached to the rear surface thereof from a plurality of directions. A slide guide groove to
The position of the mounting hole can be changed by changing the direction in which the mounting bracket is inserted into the device body.

  The “slide guide groove” guides the mounting bracket to the mounting position by shifting the mounting bracket relative to the device main body.

  According to the device of the present invention, by changing the mounting direction of the mounting bracket with respect to the orthogonal slide guide groove on the back of the device body and changing the position of the mounting hole, the mounting specification corresponding to the installation conditions of the device should be obtained. Can do. For example, when mounting on a horizontally long support frame, the mounting bracket is inserted into the slide guide groove sideways with respect to the device body, and when multiple devices are to be placed side by side in a row, It is only necessary to insert the mounting bracket into the slide guide groove in the vertical direction with respect to the device main body, and the operation for changing the mounting specification becomes easy.

  In addition, a device having a pair of mounting holes on the outside of the device body can be configured by simply mounting one mounting bracket having mounting holes at both ends on the device body. It is only necessary to attach a single mounting bracket. For example, a pair of mounting brackets each having a single mounting hole are mounted at appropriate positions on the main body of the device, and the mounting specifications are changed at a lower cost. In addition, it is not necessary to change the installation specifications.

  In addition, since there is a pair of mounting holes on the outside of the device body at the outer periphery facing part, the mounting holes are arranged in a straight line so that the pair of mounting holes face each other. When machining the lower holes, the lower holes may be arranged and formed in a straight line, and the machining operation becomes easier as compared with the conventional example in which the left and right mounting holes are displaced vertically.

  Furthermore, the mounting bracket can be removed when not screwed and fixed or when storing in a package. It is also possible to prepare a plurality of types of mounting brackets having different sizes and mounting hole positions, and to use the mounting brackets properly according to the installation conditions.

  Therefore, it is possible to easily change the installation specifications of the equipment even at the installation site, and to perform installation according to the installation conditions. In addition, since the mounting specifications are changed by changing the mounting direction of the mounting bracket, it can be implemented at a lower cost compared to preparing multiple types of equipment body, and it has excellent practical convenience. Become. Moreover, since the apparatus main body from which the mounting bracket is removed has a simple outer shape without large protrusions, it is advantageous in terms of packaging, transportation, storage, and the like.

  (3) In one Embodiment of the apparatus of this invention, the said attachment bracket has a small protrusion which protrudes in the direction orthogonal to an insertion mounting direction, and contact | abuts to the said apparatus main body in the said slide guide location.

  “Small protrusion” refers to a small protrusion that does not hinder the mounting of the mounting bracket, and this small protrusion preferably hits the device body in a point or line contact state.

  According to this embodiment, since the small protrusion of the mounting bracket contacts the device main body and is mounted on the device main body without any backlash, it is not necessary to particularly increase the accuracy of the slide guide portion.

  (4) In another embodiment of the device according to the present invention, the case of the device body protrudes in a direction perpendicular to the insertion mounting direction of the mounting bracket at four positions of the slide guide portion and contacts the mounting bracket. Small protrusions that come into contact are formed integrally.

  It is preferable that the small protrusions abut on the mounting bracket on both sides in the width direction of the mounting bracket to be mounted and at a total of four locations including two locations along the longitudinal direction.

  According to this embodiment, since the four projections integrally formed on the case of the device main body abut on the mounting bracket, the mounting bracket is mounted without any play on the device main body. There is no need to increase the value.

  (5) The device main body of the present invention is a device main body to which a mounting bracket having a mounting hole for screw insertion is mounted, and an orthogonal slide guide groove that allows the mounting bracket to be inserted and mounted from a plurality of directions on the back surface. I have.

  According to the device main body of the present invention, by selecting the mounting direction of the mounting bracket, a plurality of mounting specifications with different mounting hole positions or by removing the mounting bracket, a device with no mounting holes can be obtained. Therefore, it is possible to attach a device suitable for installation conditions.

  (6) The mounting bracket of the present invention is engaged with a guide rail that is engaged with a slide guide groove provided on the back surface of the device main body, a positioning stopper that abuts and engages with the device main body, and the device main body. And an elastically displaceable latching claw and a screw insertion hole.

  According to the mounting bracket of the present invention, when obtaining a device having a mounting hole, the mounting bracket can be mounted and positioned and fixed to the device body, and the mounting posture of the mounting bracket can be changed easily and without tools. It can be handled easily at the installation site.

  According to the present invention, by changing the mounting direction of the mounting bracket by changing the mounting direction of the mounting bracket with respect to the slide guide groove on the back of the device body, the mounting specifications of the device can be easily changed and installed at the installation site. Installation that meets the requirements can be performed.
