Description

  The present invention relates to a programmable display, and more particularly to its structure / housing, manufacturing method, installation method, and the like.

FIG. 6 is a schematic exploded view of a conventional programmable display device 100.
In the figure, a main body 110 is a main body portion of the programmable display device 100, and the programmable display device 100 is manufactured by assembling the main body portion so as to be housed in a space formed by two illustrated housings. The

The two cases are a front resin case 120 and a rear resin case 130 shown in the figure. In addition, these can also be regarded as what divided | segmented one housing | casing into two.
The main body 110 includes, for example, a metal frame (sheet metal) 111, a “circuit board and various circuit components” 112, a display (LCD) 113, and the like. The material (metal) of the metal frame is not particularly limited.

  The programmable display 100 is produced in such a manner that the main body 110 is finally housed in one resin casing formed by the front resin casing 120 and the rear resin casing 130. Although this manufacturing process may be various, when it is set as the manufacturing process substantially the same as patent document 1 mentioned later, for example, it becomes as follows.

  That is, first, the main body 110 is connected to the front resin casing 120 from the back side / rear side of the front resin casing 120 (the lower side in the figure; the side having the illustrated main body 110). As shown in the figure, the main body 110 may be completed and then connected to the front resin casing 120, or the components of the main body 110 may be sequentially connected to the front resin casing 120. The connection method is, for example, a general method using a screw or the like (for example, a screw hole (not shown) provided in the metal frame 111 or the like and a not shown male screw). Not limited to.

  In the drawing, the touch panel 121 and the cover sheet 122 are fixed to the front resin casing 120 from the front side (upper side in the drawing) of the front resin casing 120 (adhesion or the like). However, the present invention is not limited to this example. For example, the touch panel 121 and the cover sheet 122 may be fixed after the main body 110 is first connected to the front resin casing 120.

  Then, after connecting the main body 110 to the front resin casing 120 as described above, the front resin casing 120 and the rear resin casing 130 are connected. Thus, the main body 110 is accommodated in one resin casing formed by the front resin casing 120 and the rear resin casing 130.

  The material of the front resin case 120 and the rear resin case 130 is desirably a material that is electrically insulated, such as a resinous material (for example, the same as the metal frame (sheet metal) 111, for example). Material is not desirable).

  In addition, the connection method between the front resin housing 120 and the rear resin housing 130 may be arbitrary, but the front resin housing 120 and the rear resin are later used as in the connection method using the screws and the like. It is desirable that the casing 130 be separable (thus, the adhesive is basically NG). This is because it is necessary to perform maintenance (repair of the main body 110, etc.) later. On the other hand, the cover sheet 122 may be bonded to the front resin casing 120.

FIG. 7 is an exploded structural view of the programmable display device 100.
As shown in the drawing, the touch panel 121 and the cover sheet 122 are shown on the front side of the front resin casing 120 because the touch panel 121 and the cover sheet 122 are bonded to the front resin casing 120 from the front side as described above. It expresses what to do.

  When the main body 110 is disassembled, a metal frame (sheet metal) 111, a “circuit board and various circuit components” 112, a display (LCD) 113, and the like are obtained as shown in the figure. For example, these may be connected to the front resin casing 120 in the illustrated arrangement order. That is, the display (LCD) 113 is first connected to the front resin casing 120, then the metal frame (sheet metal) 111 is connected, and finally the "circuit board and various circuit components" 112 are connected. May be. Of course, the present invention is not limited to this example, and the main body 110 may be connected to the front resin casing 120 after the main body 110 is assembled as described above.

In any case, after the main body 110 is connected to the front resin casing 120, the front resin casing 120 and the rear resin casing 130 are connected to each other.
Further, for example, the prior art described in Patent Document 1 is known.

  In Patent Document 1, for example, as shown in FIGS. 2 and 4, a display panel assembly 20, a main frame 30, a space formed by a casing of a programmable display (a front case 10 and a rear case 40), A configuration in which the circuit board 5 (circuit component 51) and the like are accommodated is disclosed.

JP 2011-238027 A

  As described above, conventionally, it is necessary to use two resin casings 120 and 130. This is a structure in which the resin casing is divided into two parts in consideration of later maintenance (maintenance, repair, etc. of the main body 110). Thereby, for example, when the main body 110 has some trouble, the main body 110 can be easily taken out from the resin casing (and can be repaired).

  However, resin parts are generally expensive (the cost of the resin is greatly influenced by the raw material cost, volume, and charge charge. Also, it can be caused by a high yield). It is not desirable to use two resin casings. However, as described above, it is necessary to use two resin casings 120 and 130 in consideration of maintenance, replacement of internal parts, and the like.

  Moreover, when installing a programmable display in the field, attaching a programmable display to a panel not shown is often performed. Conventionally, the programmable display is attached to the panel by connecting and fixing the resin casing to the panel (panel) with a plurality of screws or the like. When the programmable display is attached to the panel (board), for example, the attachment portions at the four corners (not shown) are screwed, but the four corners are not uniformly tightened, and the resin casing may be distorted.

  As described above, depending on how to tighten a plurality of screws (such as force adjustment), the resin casing is often distorted and deformed. In addition, there is a case where a gap is generated between the two resin casings 120-130 due to distortion / deformation, and dust, dust, or the like enters. In some cases, the accumulation of dust or the like may cause problems such as hindering heat dissipation.

  The object of the present invention is to reduce the volume of the resin casing, further reduce the number of screws and the number of screw tightening steps, thereby reducing the cost and reducing the work load, and further, the distortion caused by the attachment to the panel or the like. / Providing a programmable display or the like that does not cause deformation or the like.

  The programmable display according to the present invention includes a main body having a metal frame, a display panel, and a circuit unit, a resin housing in which a space for housing the main body is formed and an opening is formed, and the resin housing in the resin housing. Connection means for connecting the main body portion accommodated in the space and the resin casing, and a cover sheet fixed to the resin casing so as to close the opening of the resin casing.

  According to the programmable display of the present invention, its manufacturing method, installation method, etc., it is possible to reduce the volume of the resin casing and further reduce the number of screws and the number of screw tightening steps, thereby reducing the cost and reducing the work load. In addition, there is no distortion / deformation associated with the attachment to a panel or the like.

It is a schematic exploded structure figure of the programmable display of this example. The state in the middle of the assembly of the structure shown in FIG. 1 is shown. It is an exploded structure figure of a programmable indicator. (A), (b) shows a mode that a programmable display is attached with respect to a panel. (A)-(e) is a figure which shows the state after attaching a programmable display to a panel. It is a schematic exploded view of a conventional programmable display. It is an exploded structure figure of the conventional programmable display.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic exploded view of the programmable display 1 of this example.
FIG. 2 shows a state during the assembly of the configuration shown in FIG.

  Here, as described above, conventionally, the housing has been divided into two parts in consideration of maintenance (repair etc.). However, at present, in the case of a failure, there are many cases where it is cheaper to replace the purchase rather than repair.

  In this method, focusing on this point, based on the idea that maintenance (repair, etc.) is basically not performed, only one resin casing is necessary (in other words, the volume of the resin casing as a whole). Proposed). An example is shown in FIG.

In the example shown in FIG. 1, the programmable display 1 schematically includes a cover sheet 2 and the like, a main body 10, a resin housing 30 and the like.
The cover sheet 2 and the like may be substantially the same as the touch panel 121 and the cover sheet 122. However, the object to which the cover sheet 2 or the like is fixed (adhered or the like) is the resin casing 30. Further, the material of the cover sheet 2 may be, for example, polyethylene terephthalate (PET) as in the conventional case, but is not limited to this example.

  The main body 10 includes, for example, a metal frame (sheet metal) 11, a “circuit board and various circuit components” 12, a display (LCD) 13, and the like. This configuration itself may be substantially the same as the conventional one, but the shape of the metal frame (sheet metal) 11 is different from the conventional one. That is, in this example, the shape of the metal frame (sheet metal) 11 is matched to the shape of the resin casing 30 (positions of grooves, screw holes, etc.) in order to connect to the resin casing 30 as shown in FIG. It has become a thing.

The “circuit board and various circuit components” 12 may be referred to as, for example, a “circuit unit” 12 or the like.
For example, as shown in FIGS. 1 and 2, the resin housing 30 is provided with a plurality of “female screws (female screws)” (screw holes) 31. The shape and size of these “female screws” (screw holes) 31 correspond to the shape and size of “male screws (male screws)” (bolts and the like) 3. The metal frame (sheet metal) 11 of the main body 10 is provided with a plurality of through holes 11a. The size of the through hole 11a is such that the thread groove portion (shaft) of the “male screw” 3 can be passed, but the head (head) portion cannot be passed.

  With the above configuration, for example, as shown in FIG. 2, the “male screw” 3 is rotated and inserted (screwed) into the “female screw” 31 while passing the shaft portion of each “male screw” 3 through each through hole 11a. Thus, the main body 10 (the metal frame 11) is connected and fixed to the resin casing 30.

  The metal frame 11 is provided with a plurality of (four in the illustrated example) projections 11b, and the resin casing 30 has a plurality of (one in four corners in the illustrated example) corresponding to the projections 11b. A total of four) through-holes 32 are provided.

  Here, the shape of the resin casing 30 is broadly divided into a frame portion 1a that forms an upper opening in the figure, and other portions (a portion that mainly accommodates the main body 10; a bottom portion 1b). ). The frame portion 1a is formed so as to spread outward from the upper portion of the bottom portion 1b (here, it can be expressed that the area of the frame portion 1a is larger than the area of the bottom portion 1b). The through hole 32 is formed in the frame portion 1a and is located outside the bottom portion 1b.

  Thus, when connecting the main body 10 to the resin casing 30 as described above, each projection 11b passes through each through-hole 32 and exits outside the resin casing 30 (of its bottom portion 1b) ( Exposed) shape. That is, when the programmable display 1 is completed, the protruding portion 11b, which is a part of the main body 10 (the metal frame 11), is in a state of being exposed (exposed) to the outside of the resin casing 30. Yes. Then, when the programmable display device 1 is fixed / installed on a panel or the like later on in the field, each of the protrusions 11b is used. Details will be described later.

FIG. 3 is an exploded structural view of the programmable display 1.
3 may be regarded as a drawing corresponding to the conventional FIG.
FIG. 3 shows the metal frame (sheet metal) 11, circuit board and various circuit components 12, display (LCD) 13 (display panel), and the like, which are obtained by disassembling the main body 10. In the illustrated example, the metal frame (sheet metal) 11 is composed of two metal frames, a metal frame 11-1 and a metal frame 11-2. The main body 10 is formed in such a manner that the LCD 13 is sandwiched between the two metal frames 11-1 and 11-2. However, the present invention is not limited to this example. Conventionally, there are cases where there are one metal frame and two metal frames depending on the structure of the LCD (FIG. 7 shows only one example).

  Moreover, the said cover sheet 2 etc. consist of the illustrated cover sheet 2 and the touch panel 4, for example. However, the present invention is not limited to this example. At the time of assembly, the touch panel 4 is attached (adhered or the like) to the metal frame 11, so the touch panel 4 may be included in the main body 10 from the beginning to create the main body 10. . Therefore, in this example, the cover sheet 2 or the like means only the illustrated cover sheet 2, and the main body 10 includes a metal frame (sheet metal) 11, a circuit board and various circuit components 12, a display (LCD) ) 13 is constituted by the touch panel 4. The touch panel 4 is attached to the metal frame 11 so as to overlap the display (LCD) 13 (front side; upper side in FIG. 1).

  After connecting and fixing the main body 10 to the resin casing 30 as described above, the cover sheet 2 is fixed (adhered or the like) to the resin casing 30. This fixes (adheres, etc.) the cover sheet 2 to the resin casing 30 so as to close the opening of the resin casing 30. For example, this is bonded with a double-sided tape. For example, the outer peripheral portion of the back surface of the cover sheet 2 is bonded to the illustrated peripheral edge portion 33 formed on the frame portion 1 a of the resin housing 30. Thereby, the programmable display 1 of this example is completed. The programmable display device 1 of this example may be regarded as a main body 10 accommodated in a space formed by the cover sheet 2 and the resin casing 30.

  As described above, since the programmable display 1 of this example requires only one resin casing (in other words, the volume of the resin casing as a whole is reduced), a cost reduction effect can be obtained. . Further, conventionally, there has been a case where a gap is generated between two resin casings due to distortion / deformation accompanying installation on the panel, and dust, dust, etc. may invade. In this example, there is one resin casing. Therefore, such a problem cannot occur. Also, as will be described later, the distortion / deformation itself is very small in the first place.

However, as described above, it is basically assumed that maintenance (repair etc.) is not performed.
According to the programmable display 1 described above, the following effects can be obtained in addition to the above effects.
-Since the number of parts is reduced, the costs incurred when managing parts can be reduced.
・ Since no screws are required to connect the two resin casings, the cost of the screws and the number of manufacturing steps can be reduced.
-Resin parts have a high yield due to moldability, but since the resin parts are reduced, the yield can be reduced.

  Hereinafter, with reference to FIG. 4 and FIG. 5, for example, a method of installing the programmable display 1 manufactured on the manufacturer side or the like on a panel or the like at the installation location in the PLC system or the like on each user side will be described.

4 (a) and 4 (b) show how the programmable display 1 is attached to the panel.
Fig.5 (a)-(e) shows the state after attaching the programmable display 1 to a panel.

4 (a) shows only the front side and FIG. 4 (b) shows the state seen from the back side, and therefore, the following description will be made collectively as FIG. 4 without making any particular distinction.
5A is a front view, FIG. 5B is a side view, FIG. 5C is a rear view, and FIG. 5D is a top view. FIG. 5E is a cross-sectional view taken along the line AA ′ shown in FIG.

  First, as described above, the programmable display 1 is composed of the frame portion 1a and the bottom portion 1b in appearance. Further, as already described, it is assumed that “the area of the frame portion 1a> the area of the bottom portion 1b”.

  On the other hand, a hole 5 a is provided in the panel 5 where the programmable display 1 is installed. The size (area) of the hole 5a is smaller than the frame portion 1a and slightly larger than the bottom portion 1b. That is, there is a relationship of “the area of the frame portion 1a> the area of the hole 5a> the area of the bottom portion 1b”. Therefore, the bottom portion 1b can pass through the hole 5a, but the frame portion 1a cannot pass through the hole 5a. Therefore, when trying to pass the programmable display device 1 from the bottom portion 1b side through the hole 5a, the programmable display device 1 is stopped in a state where the back side of the frame portion 1a is in contact with the panel 5.

  As described above, the programmable display 1 is mounted using the mounting bracket 6 and the mounting nut 7 in a state where the bottom portion 1b of the programmable display 1 is passed through the hole 5a and the back side of the frame portion 1a is in contact with the panel 5. Fix to panel 5.

  Here, in this example, the programmable display 1 is fixed to the panel 5 by connecting each “pair of the mounting bracket 6 and the mounting nut 7” to each of the protrusions 11b. That is, the attachment to the panel 5 is realized by using a part of the metal frame instead of the resin casing as in the prior art. Naturally, the metal frame can be distorted less than the resin casing (it is hardly distorted only by screw tightening), so that the conventional problem can be solved.

  From the above, the shapes / structures of the mounting bracket 6 and the mounting nut 7 are not particularly important, and only an example is shown in FIGS. 4 and 5, and the present invention is not limited to this example. Therefore, these will be described briefly.

  First, in a state where the bottom portion 1b of the programmable display 1 is passed through the hole 5a, the four protrusions 11b are located at the four corners of the hole 5a. Thus, as shown in FIG. 4 and FIG. 5C, the four “pairs of mounting bracket 6 and mounting nut 7” are connected to the four protrusions 11b at the four corners of the hole 5a. To do. Although this connection method may be various, here, an example shown in FIG. 5E will be described.

  In the example shown in FIG. 5E, first, the mounting bracket 6 is provided with a hole 6a that can penetrate the protruding portion 11b. For example, when it is considered that the mounting bracket 6 having a shape close to a square is divided into four in a square shape, the hole 6a may be provided in one of the four divided regions. It is not restricted to this example.

  Then, for example, as shown in FIG. 5 (c), the projection 11b is passed through the hole 6a, and the other three divided areas are in contact with the panel 5 body (portion other than the hole 5a). The metal fitting 6 is arranged. In this state, for example, as shown in FIG. 5 (e), the mounting nut 7 is connected to the protrusion 11b. For example, as shown in FIG. 5 (c), the projection 11 b is inserted into the illustrated hole 7 a of the mounting nut 7 and the tip of the mounting nut 7 abuts against the mounting bracket 6. Is connected.

  This is particularly in the form of pressing (pressing) the mounting bracket 6 (the other three divided regions) against the panel 5 body by the mounting nut 7, and the mounting nut 7 is connected to the protrusion 11 b. Thus, the programmable display 1 is connected to the panel 5 in such a manner that the metal frame 11 is pulled toward the back side in the drawing (thereby pressing the frame portion 1a of the resin casing 30 against the panel 5 (the front side)). Will be attached to.

  Although not specifically shown in the figure, for example, as an example, a not-shown “female screw” is cut in the hole 7 a of the mounting nut 7, and a not-shown “male screw” corresponding to this is a protrusion. 11b may be used (that is, it may be a screw-tightened configuration. Of course, the present invention is not limited to this example. In this example, the mounting nut 7 is, for example, a “hex nut”). It does not matter.)

  In any case, as a result, the programmable display 1 is fixed to the panel 5 in such a form that the resin casing 30 of the programmable display 1 is pressed against the panel 5 (the front side thereof). 7 or the like is a projection 11b that is a part of the metal frame. Therefore, for example, even if there is some unevenness in the force applied when each mounting nut 7 is connected to each projection 11b (screw tightening or the like), the resin housing 30 will not be distorted (the distortion of the metal frame is extremely Should be less).

  Further, as described above, the metal frame 11 is attached by being pulled to the back side of the panel 5 by the “pair of the attachment metal fitting 6 and the attachment nut 7”, whereby the metal frame 11 is attached to the resin casing 30. The frame portion 1a is pressed against (pressed on) the panel 5 (the front side). That is, the programmable display device 1 is fixed to the panel 5 in such a manner that a part of the resin casing 30 (frame portion 1 a) is pressed against the panel 5. This can be considered that there is no particular problem even if the main body 10 and the resin casing 30 are not connected by the “male screw” 3 after the programmable display 1 is attached to the panel 5. That is, the main body 10 and the resin housing 30 can be substantially connected by the pressing force.

  Accordingly, as a modified example, it may be considered that the main body 10 and the resin casing 30 are not connected by the “male screw” 3. However, in the case of this modification, there is no problem after the programmable display 1 is attached to the panel 5, but there is a possibility that some problems will occur in the previous stage.

  That is, the main body 10 may move around in a space surrounded by the resin casing 30 and the cover sheet 2 during transportation from the manufacturer side to each user side (installation location). This may cause some problem (such as an impact on the main body 10 causing a failure, or the main body 10 breaking the cover sheet 2 and going out of the resin housing 30).

  In order to cope with this problem, a plurality of hooks 34 may be formed on the inner surface of the resin casing 30 (not shown), for example, as shown in FIGS. When the resin casing 30 is regarded as a rectangle composed of two long sides and two short sides, in the illustrated example, two hooks 34 are provided on the long side and on the short side. One hook 34 is provided. 1 and 2 are perspective views, only one of two hooks 34 is shown for both the long side and the short side, but naturally the hook 34 is also formed on the other side. .

  Further, in FIG. 1 and the like, when the main body 10 is inserted into the resin casing 30 from the upper side in the figure, the hook 34 is inserted into the main body 10 in such a manner that the hook 34 itself is slightly deformed although there is some resistance. Is forgiving. However, once the main body 10 is inserted into the resin casing 30, a hook 34 (not shown in particular) of the main body 10 is configured to be hooked. This can be said that the main body 10 is loosely connected (temporarily fixed) to the resin casing 30. Accordingly, in this state, even if the user or the like simply lifts the main body 10 upward in the figure, the main body 10 cannot be removed from the resin casing 30. Therefore, it is possible to prevent / suppress the above problem from occurring during transportation.

  And in the state which attached the programmable display 1 to the panel 5 by the said structure, as mentioned above, the metal frame 11 of the main body 10 presses the resin housing | casing 30 (the frame part 1a) against the panel 5, firmly. Will be fixed.

  In this manner, the main body 10 may be temporarily fixed to the resin casing 30 in such a manner that each part of the main body 10 is hooked on each hook 34. In addition, since such a structure may be diverted from the existing general structure, detailed illustration and description will not be given here. However, in this example, the “male screw” 3 and the like and the installation work thereof are not particularly necessary (although they may be performed), the cost reduction effect and work load reduction effect can be obtained (the number of screws and screw tightening man-hours can be reduced) Can be reduced).

As described above, the programmable display device 1 of this example may be regarded as having the following configurations, for example.
A main body (10) having a metal frame (11), a display panel (13), and a circuit unit (12);
A resin housing (30) in which a space for accommodating the main body (10) is formed and an opening is formed;
Connection means for connecting the main body (10) accommodated in the space in the resin housing (30) and the resin housing (30) (for example, the “male screw” 3 and the “female screw” 31) Or the plurality of hooks 34 etc.);
A cover sheet (the cover sheet 2 or the like) that is bonded to the resin casing (30) so as to close the opening of the resin casing (30);
For example, the metal frame (11) has a plurality of protrusions (11b).

  The resin casing (30) has a plurality of holes (32) corresponding to the plurality of protrusions (11b). And each protrusion part (11b) penetrates each hole (32), and is exposed to the outer side of the resin housing | casing (30).

  From this, when attaching the said programmable display 1 to arbitrary panels (5), said each protrusion part (11b) is utilized. That is, the second connection means (for example, “a pair of the mounting bracket 6 and the mounting nut 7”) connected to the protrusions (11b) exposed to the outside of the resin casing (30) as described above, The programmable display 1 is fixed to the panel (5).

  Then, for example, each of the second connecting means is connected to each protrusion (11b) on the back side of the panel (5), so that the resin housing is provided on the front side of the panel (5) via the metal frame (11). The programmable display 1 is fixed to the panel (5) by pressing the body (30) against the panel (5).

  According to the programmable display 1, the manufacturing method, the installation method, etc., the volume of the resin casing can be reduced, and further the number of screws and the number of screw tightening steps can be reduced, thereby reducing the cost and reducing the work load. In addition, there is no distortion / deformation associated with the attachment to a panel or the like.
