Further, in the following description of the position and direction, the position and direction when viewed from the front are used as the normal mounted state of the in-panel device 1 as shown in FIG.

The in-board device 1 includes a rectangular parallelepiped casing 11, various electronic components (not shown) housed in the casing 11, and the like. The housing 11 has a front surface 11a, an upper surface 11b, a lower surface 11c (see FIG. 2), a right side surface 11d, a left side surface 11e, and a rear surface 11f (see FIG. 3). First to sixth connection connectors 12 to 17 are provided on the upper end portion on the front side of the in-board device 1. These first to sixth connection connectors 12 to 17 are exposed on the upper surface 11b of the housing 11, and the cable 18 is connected from above the housing 11.

As shown in FIG. 2, seventh to tenth connection connectors 21 to 24 are provided at the lower end of the in-board device 1. These seventh to tenth connection connectors 21 to 24 are provided so as to be exposed on the lower surface 11c of the housing 11. It is desirable that the seventh to tenth connection connectors 21 to 24 are connected to the cable 18 while visually confirming the connection position, and the cable 18 is led out downward from the in-board device 1 in the proper mounting state. Is configured.
As shown in FIG. 3, a rail groove 25 into which the DIN rail 5 is fitted is formed on the rear surface 11f of the housing 11 of the in-board device 1, and a plurality of vertically extending mounting pieces 26 are provided. ing. The rail groove 25 is continuously formed from the left end to the right end of the in-board device 1 without interruption.

The DIN rail 5 is a rail formed based on the German industrial standard. As shown in FIG. 4, the DIN rail 5 includes a strip-shaped flat plate portion 5a extending in the left-right direction and a first rail projecting from one side portion (upper side in FIG. 4) of the flat plate portion 5a. It has a portion 5b and a second rail portion 5c protrudingly provided on the other (lower side in FIG. 4) side portion of the flat plate portion 5a. A large number of elongated holes 5d for inserting screws are formed in the flat plate portion 5a. As shown in FIG. 3, the first rail portion 5b and the second rail portion 5c are each formed in an L-shaped cross section. The first rail portion 5b extends forward and upward from the flat plate portion 5a. The second rail portion 5c extends forward and downward from the flat plate portion 5a.

The mounting pieces 26 are arranged at two positions in the left-right direction of the in-panel device 1 so as to sandwich the DIN rail 5 from the vertical direction. Further, the mounting pieces 26 move toward the DIN rail 5 so that the upper first rail portion 5b and the lower second rail portion 5c of the DIN rail 5 cooperate with the in-board device 1. And pinch. In this way, by sandwiching the upper and lower ends of the DIN rail 5 between the four mounting pieces 26 and the in-board device 1, the in-board device 1 is attached to the DIN rail 5.

A locking mechanism (not shown) is provided on the attachment piece 26, and when the mounting piece 26 is moved to the DIN rail 5 side, the locking mechanism restricts the movement in the return direction.
The in-panel device 1 mounted on the DIN rail 5 by the four mounting pieces 26 is movable in the left-right direction along the DIN rail 5. In this embodiment, in order to regulate the movement of the in-panel device 1 in the left-right direction, the stoppers 27 are attached to the DIN rail 5 at positions sandwiching the in-panel device 1 from the left-right direction. There is.

As shown in FIG. 3, these stoppers 27 include a main body 27a that contacts the DIN rail 5 from the front, a movable member 27b that moves in the front-rear direction inside the main body 27a, and a movable member that penetrates the main body 27a. The fixing screw 27c screwed into 27b is provided. The movable member 27b is formed in a gate shape that comes into contact with the first and second rail portions 5b and 5c of the DIN rail 5 from behind. The movable member 27b moves forward when the fixing screw 27c is tightened, and cooperates with the main body 27a to clamp the first and second rail portions 5b and 5c. Since the stopper 27 is fixed to the DIN rail 5 and the movement path of the in-board device 1 is cut off, the in-board device 1 cannot move in the left-right direction.

As shown in FIGS. 1 and 2, the mounting structure 3 includes support brackets 4 and 4 positioned on both sides of the in-board device 1, and these two support brackets 4 and 4 via rotary structures 31 respectively. It has a DIN rail 5 connected thereto.
The support bracket 4 is formed by bending a metal plate material into an L shape, and has a mounting portion 4a and an arm portion 4b. The mounting portion 4a is mounted on the rear wall 2 with mounting screws 32. The arm portion 4b extends forward from the mounting portion 4a. A through hole 33 (see FIG. 4) is formed in the arm portion 4b, and the rotating structure 31 is provided using the through hole 33. The opening shape of the through hole 33 is a hexagon. The opening shape of the through hole 33 is not limited to the hexagon, and may be any shape as long as it is not circular. The opening shape of the through hole 33 may be, for example, a polygon such as a triangle or a quadrangle, or an ellipse.

As shown in FIG. 4, the rotary structure 31 according to this embodiment is composed of two dampers 34, 34. As shown in FIG. 5, each of the dampers 34 has a prismatic housing 35 and a shaft 36 protruding from one end of the housing 35.
A bearing 37 and a holding mechanism 38 are provided in the housing 35. FIG. 5 schematically shows the structure inside the housing 35. The shapes and positions of the bearing 37 and the holding mechanism 38 shown in FIG. 5 are different from the actual ones. In this embodiment, the shaft 36 corresponds to the "shaft portion" according to the present invention, and the bearing 37 corresponds to the "bearing portion" according to the present invention.

The housing 35 is attached to the DIN rail 5 with the attaching screw 39 (see FIG. 4) in a state where the axis C1 of the shaft is parallel to the longitudinal direction of the DIN rail 5.
The bearing 37 rotatably supports the shaft 36, and is accommodated in the housing 35 in a state where one end portion 36 a of the shaft 36 projects from the housing 35. One end 36 a of the shaft 36 is formed in a hexagonal column shape and fits into the through hole 33 of the support bracket 4. Therefore, the shaft 36 cannot rotate with respect to the support bracket 4. The shape of the one end portion 36a of the shaft 36 is not limited to the hexagonal column shape, and may be any shape as long as it is not a columnar shape. The shape of the one end portion 36a of the shaft 36 may be, for example, a prismatic columnar shape such as a triangular prismatic shape or a quadrangular prismatic shape, or an elliptical columnar sectional shape.
Although not shown in detail, the holding mechanism 38 applies a braking force to the shaft 36 by the resistance and frictional resistance associated with the deformation of the elastic piece when the shaft 36 rotates about the bearing 37. 36 is held at a predetermined position in the rotating direction.

In the electronic device mounting structure 3 configured in this manner, for example, by pulling the upper part of the in-panel device 1 forward or pushing it backward, the in-panel device 1, the DIN rail 5, and the housing of the damper 34 are 35 rotates integrally with the shaft 36. In the in-board device 1, from the use position shown by the solid line in FIG. 6, the front surface 11a of the housing 11 turns to a first turning position P1 in which the front surface 11a is directed obliquely downward and downward, and the front surface 11a is directed obliquely upward and upward. It can turn to the second turning position P2. When the in-board device 1 is in the first turning position P1, the upper surface 11b of the housing 11 can be viewed from the front. When the in-board device 1 is in the second turning position P2, the lower surface 11c of the housing 11 can be visually recognized from the front.

Therefore, according to this embodiment, the operator can easily visually recognize the upper surface 11b and the lower surface 11c of the in-panel device 1 from the front side in a state where the in-panel device 1 is attached to the rear wall 2. Therefore, although the in-panel device 1 according to this embodiment has the upper surface 11b and the lower surface 11c provided with the first to tenth connection connectors 12 to 17 and 21 to 24, Wiring work can be easily performed from the front. Further, although not shown, when an operation unit is provided on the upper surface 11b or the lower surface 11c of the in-panel device 1, the operation of the operation unit can be easily performed from the front side.

Since the in-panel device 1 according to this embodiment is rotatable so that the upper surface 11b and the lower surface 11c are directed to the front, it is necessary to connect a cable while visually checking the connection position (for example, a connector). The seventh to tenth connection connectors 21 to 24) can be provided on the upper surface 11b or the lower surface 11c of the in-board device 1. For this reason, even if you use a connector that requires you to connect the cable while visually checking the connection position, the cable connection does not have to be exposed on the front surface. There is no need for an openable cover to cover and hide. Therefore, by adopting the mounting structure 3 for the in-panel device 1, it is possible to reduce the number of parts constituting the in-panel device 1.

The rotating structure 31 according to this embodiment includes a housing 35 configured to accommodate the bearing 37 with one end 36a of the shaft 36 protruding. The shaft 36 is fixed to the support bracket 4, and the housing 35 is fixed to the DIN rail 5. According to this rotating structure 31, since the shaft 36 is supported by the bearing 37, the shaft 36 rotates smoothly with respect to the bearing 37. Therefore, according to this embodiment, since the in-panel device 1 can be smoothly rotated, it is possible to provide a mounting structure for an electronic device that has good workability when the cable is attached and detached.

The rotating structure 31 according to this embodiment includes a holding mechanism 38 configured to hold the DIN rail 5 at a predetermined position in the rotating direction. Therefore, the in-panel device 1 can be stopped at an arbitrary position, so that the cable 18 can be attached and detached more easily.

(Modification of support bracket)
The support bracket may be configured as shown in Figures 7-10. In these figures, the same or equivalent members as those described with reference to FIGS. 1 to 5 are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.
The DIN rail 5 shown in FIG. 7 is inserted into the through hole 41 formed in the support bracket 4 and penetrates the support bracket 4. As shown in FIG. 8, the through hole 41 has a shape along an arc 42 centered on the shaft 36 and includes a movement range when the DIN rail 5 rotates when viewed from the axial direction of the shaft 36. Has been done.

In this embodiment, since the DIN rail 5 can be passed through the through hole 41, the support bracket 4 is arranged at a position adjacent to the right side surface 11d and the left side surface 11e of the in-board device 1, as shown in FIG. be able to. According to this embodiment, since the support bracket 4 substantially functions as the stopper 27, the stopper 27 is unnecessary.
The through hole 41 of the support bracket 4 can be formed as shown in FIG. The through hole 41 shown in FIG. 10 is formed so that the length of the arc 43 centered on the shaft 36 is shorter than that of the arc 42 shown in FIG. 7.

For this reason, the through hole 41 shown in FIG. 10 has contact surfaces 44 and 45 that contact the DIN rail 5 that rotates together with the in-board device 1. According to this embodiment, the moving range of the DIN rail 5 can be defined by the contact surfaces 44 and 45. That is, the through hole 41 shown in FIG. 10 is formed in a shape that defines the movement range of the DIN rail 5. By adopting this embodiment, it is possible to prevent the in-panel device 1 from being rotated excessively and colliding with the rear wall 2.

In this embodiment, the shaft 36 of the damper 34 is fixed to the support bracket 4, and the housing 35 is fixed to the DIN rail 5. However, the present invention is not limited to such a limitation and can be implemented even if the shaft 36 is fixed to the DIN rail 5 and the housing 35 is fixed to the support bracket 4.

(Second embodiment)
The rotating structure 31 can be configured as shown in FIGS. 11 to 13. 11 to 13, members that are the same as or equivalent to those described with reference to FIGS. 1 to 10 are given the same reference numerals and detailed description thereof is omitted as appropriate.
The rotating structure 51 shown in FIG. 11 includes a circular guide hole 52 formed in the support bracket 4 and an insertion portion 53 of the DIN rail 5 inserted into the guide hole 52. In this embodiment, the guide hole 52 corresponds to the "bearing portion" in the present invention, and the insertion portion 53 corresponds to the "shaft portion" in the present invention.

As shown in FIG. 12, the guide hole 52 is formed in the support bracket 4 so as to penetrate therethrough. The diameter of the guide hole 52 is the same as the width of the flat plate portion 5a of the DIN rail 5.
The insertion portion 53 is inserted into the guide hole 52 in a fitted state. As shown in FIG. 12, the insertion portion 53 according to this embodiment is composed of a convex portion 53a formed so as to partially project in the longitudinal direction at the longitudinal end portion of the flat plate portion 5a. By being inserted into the guide hole 52, the convex portion 53a comes into contact with the hole wall surface of the guide hole 52 and is rotatably supported. That is, the guide hole 52 rotatably supports the convex portion 53a around the axis formed by the center line C2 of the convex portion 53a. By setting the diameter of the guide hole 52 so that the entire DIN rail 5 can be inserted in the fitted state, the insertion portion 53 can be formed by the entire end of the DIN rail 5, and the convex portion can be formed. It becomes unnecessary to provide 53a.

The support bracket 4 according to this embodiment is formed of an elastic material so that the arm portion 4b can be bent and can be inclined with respect to the mounting portion 4a. A plurality of protrusions 55 are provided on the inner side surface 54 (the surface facing the in-board device 1) of the arm 4b of the support bracket 4 as shown in FIG. These protrusions 55 are each formed in a hemispherical shape, and are provided at positions that divide an imaginary circle 56 surrounding the guide hole 52 at equal intervals in the circumferential direction. The diameter of the imaginary circle 56 is equal to or slightly smaller than the total width of the DIN rail 5. Therefore, by inserting the convex portion 53a of the DIN rail 5 into the guide hole 52, the portions adjacent to the convex portion 53a of the DIN rail 5, that is, the first rail portion 5b and the second rail portion 5c, respectively, are formed. It comes to engage between the protrusion 55 and the protrusion 55.

When the DIN rail 5 is rotated together with the in-board device 1 in this engaged state, the protrusion 55 is pushed by the first and second rail portions 5b and 5c, and the arm portion 4b of the support bracket 4 bends. As the DIN rail 5 further rotates while the arm portion 4b bends in this manner, the first and second rail portions 5b and 5c pass over the protrusion 55. The mounting angles of the DIN rail 5 and the in-board device 1 change as the first and second rail portions 5b and 5c pass over the protrusion 55 and the engagement position changes. After the angle is changed, the first and second rail portions 5b and 5c are held between the protrusions 55, so that the in-panel device 1 is held at that position.

In the rotating structure 51 according to this embodiment, since the insertion portion 53 of the DIN rail 5 is inserted into the guide hole 52 of the support bracket 4 in a fitted state, components other than the support bracket 4 and the DIN rail 5 are used. Can be realized without doing. Therefore, according to this embodiment, it is possible to provide a mounting structure for an electronic device that has a simple structure and is easy to assemble.

The insertion portion 53 of the DIN rail 5 according to this embodiment is formed by the convex portion 53a of the DIN rail 5. Further, the first and second rail portions 5b and 5c of the DIN rail 5 are engaged with a plurality of protrusions 55 provided around the guide hole 52.
Therefore, although the support bracket 4 and the DIN rail 5 are not used for realizing the rotating structure 51, the in-board device 1 can be held at a predetermined position in the rotating direction. Therefore, by adopting this embodiment, it is possible to provide a mounting structure for an electronic device which is not only easy to assemble but also easy to use.

The mounting structure of the electronic device according to this embodiment can be used as shown in FIG.
The pair of support brackets 4 and 4 shown in FIG. 13 are provided at positions adjacent to the right side surface 11d and the left side surface 11e of the housing 11 of the in-panel device 1. The DIN rail 5 is formed to have a length that matches the distance between the support brackets 4.
By adopting this usage pattern, the movement of the in-board device 1 in the longitudinal direction of the DIN rail 5 can be restricted by the support bracket 4, so that the stopper 27 is not necessary.

(Modification of DIN rail)
The DIN rail used for implementing the mounting structure of the electronic device according to the present invention can be formed as shown in FIGS. 14 to 16.
The DIN rail 5 shown in FIG. 14 has a plurality of notches 61 that divide the first rail portion 5b in the longitudinal direction and a plurality of notches 62 that divide the second rail portion 5c in the longitudinal direction. There is. These notches 61 and 62 divide the first and second rail portions 5b and 5c at the same position in the longitudinal direction.

A plurality of grooves 63 are formed in the flat plate portion 5a of the DIN rail 5. These grooves 63 are provided at positions corresponding to the cutouts 61 and 62, and extend from the cutout 61 of the first rail portion 5b to the second rail portion 5c in a direction orthogonal to the longitudinal direction of the DIN rail 5. To the notch 62. Further, these grooves 63 are formed on both front and back surfaces of the flat plate portion 5a, as shown in FIG. The grooves 63 are preferably provided on both the front and back surfaces of the flat plate portion 5a, but may be provided only on the front surface or the back surface of the flat plate portion 5a.

A chamfer 66 is applied to each of a boundary portion between the outer surface 64 of the first rail portion 5b and the cutout 61 and a boundary portion between the outer surface 65 of the second rail portion 5c and the cutout 62. .. The outer surfaces 64 and 65 mentioned here are surfaces that are oriented in the up-down direction when the DIN rail 5 is in use. The chamfer 66 is a so-called R chamfer and is formed such that the boundary portion between the outer side surfaces 64 and 65 and the notches 61 and 62 is rounded into an arc shape. The chamfer 66 is not limited to the R chamfer, but may be a so-called C chamfer that connects the boundary portions between the outer surfaces 64 and 65 and the cutouts 61 and 62 with an inclined surface.

Thus, the DIN rail 5 having the notches 61 and 62 and the groove 63 can be easily cut by repeatedly bending it around the groove 63. Therefore, this DIN rail 5 does not require a dedicated tool such as a rail cutter to cut the DIN rail 5 into a length suitable for the size of the self-standing board or the in-board equipment 1.
Further, since the DIN rail 5 is chamfered 66 at the boundary between the outer side surfaces 64 and 65 and the notches 61 and 62, a sharp corner is formed on the cut surface after cutting at the groove portion. Never. Therefore, this DIN rail 5 does not need to have an end cap (not shown) attached to its end in order to cover a sharp corner.

(Modification of support bracket)
