Description

  The present invention relates to a casing sealing structure, and more particularly to a sealed casing structure that waterproof and dustproof an electrical apparatus or a mechanical apparatus.

  Conventionally, when installing electrical equipment or mechanical devices outdoors, or when installing these devices in harsh places in indoor environments with high humidity and dust concentration, a housing is provided outside the device to isolate it from the outside. To protect the device. The housing is mainly composed of a storage portion and a lid portion, and many studies and proposals have been made on the sealing material used for the joint portion between them.

  As an example of this, in Japanese Patent Application Laid-Open No. 11-16997 (Patent Document 1), a gasket is disposed in a fitting portion between a storage portion and a lid portion. FIG. 10 shows a structural diagram of Patent Document 1, but the sealed housing is composed of a storage portion 10 and a storage portion 20, and a fitting portion is formed in each case so that they can be fitted to each other. A gasket (rubber packing 30) is disposed between the fitting portions, and the device stored inside is protected from the outside air. As another example, there has been proposed one using a liquid sealing material as in Japanese Utility Model Laid-Open No. 4-118833 (Patent Document 2).

Japanese Patent Laid-Open No. 11-16997 Japanese Utility Model Publication No. 4-118833

  However, in Patent Document 1, when the sealing material is installed in a severe place in the outside air environment, the sealing material is hardened, and it is difficult to maintain the sealing performance. Further, when a certain pressure is applied to the sealing material to ensure sealing performance, a large number of system stoppers such as screws and claws for engaging the storage portion and the lid portion are required. Since the system stop material is provided outside the sealing material to secure a space inside the housing, there arises a problem that the housing is enlarged.

Moreover, in patent document 2, when filling the liquid sealing material over the entire circumference of the groove portion provided in the storage portion, if the width of the groove portion is narrow, it is difficult to inject the liquid sealing material into the appropriate groove portion. If the liquid sealing material is not properly injected, the sealing performance of the sealed casing is lowered.

  In view of the above problems, an object of the present invention is to provide a sealed housing capable of maintaining high sealing performance and easily injecting a liquid sealing material.

In order to solve the above-described problems, the present invention has the following sealed casing configuration. That is, in claim 1, at least two sealing members fitted by the mutual fitting portions provided in each, and a liquid sealing material filled in the fitting gap formed by the mutual fitting portions In addition, an external groove is formed outside the sealed housing by fitting the seal member into a sealed housing that stores a predetermined device in a sealed space formed between the sealed members. As a basic configuration, among the sealing members, one sealing member has a groove-shaped fitting portion, the other sealing member has a protruding fitting portion, and the fitting gap is A change may be made so that an external fitting gap is formed by the outer surface of the protruding fitting portion, the inner surface of the groove fitting portion, and the coupling surface coupled to the outer groove. In addition, the outer groove is modified so that the opening width in the cross section of the outer groove is larger than the separation width between the inner surface of the groove-type fitting portion and the outer surface of the protruding fitting portion. Further, the outer groove may have a maximum opening width in a cross section of the outer groove and continuously increase with the coupling surface as a reference surface.

Moreover, in the sealed housing according to claim 5, at least one concave processed portion is formed on the outer surface of the protruding fitting portion. Further, the fitting gap has an inner fitting gap formed by an inner surface of the protruding fitting portion and an inner surface of the groove fitting portion, and the protruding fitting portion is At least one notch may be formed. The fitting gap further includes an inner fitting gap formed by an inner surface of the protruding fitting portion and an inner surface of the groove fitting portion, and the one sealing member and At least one of the other sealing members is abutted before the end portion of the protruding fitting portion and the bottom portion of the groove fitting portion are in contact with each other, and between the end portion and the bottom portion. A contact surface for forming a communication path may be provided.

  Furthermore, in the sealed housing according to claim 8, the protruding fitting portion and the groove fitting portion may be engaged by a system stop material, and the one sealing member and the other sealing member may be engaged. At least one of the members provided with at least one gate formed in a recess shape coupled to the outer groove, the liquid sealing material supplied to the gate being guided to the outer groove; You may arrange in the state.

  According to the present invention, an external groove is formed in the sealed housing, and the layout is made such that the opening width which is a wide groove width is exposed in the external groove, so that the liquid sealing material can be easily injected. It becomes. Since the external groove is integrally coupled with the external fitting gap having a relatively narrow groove width, the liquid sealing material injected into the fitting groove does not overflow to the outside of the sealed housing, and the external fitting is performed. The gap is filled into a good sealed state.

In addition, when a notch is provided in the protruding fitting portion formed on the lid, resistance to the liquid sealant is suppressed in the region near the notch, and the liquid sealant is provided in a region with low resistance. Since they are sequentially supplied, the liquid sealing material can be efficiently filled in the external fitting gap 71. Further, the external fitting gap and the internal fitting gap 7 are communicated with each other by the notch, and the external groove, the external fitting gap, and the internal fitting gap form a substantially U-shaped integral groove. The liquid sealing material is also filled in the internal fitting gap to make a better sealed state.

Furthermore, when the external fitting gap and the internal fitting gap are communicated over the entire circumference of the external groove by the communication path, the external groove, the external fitting gap, and the internal fitting gap are substantially U-shaped accordingly. Since the integral groove is formed, the liquid sealing material is also filled in the internal fitting gap portion to achieve a better sealing state.

  Furthermore, since the position where the liquid sealing material is supplied is unified at a predetermined location by providing the gate, when the liquid sealing material is supplied over the entire circumference of the external groove formed outside the sealing housing, the liquid It is not necessary to move the spout of the sealing material along the external groove, and the liquid sealing material injection operation is simplified.

  In addition, after the lid portion and the storage portion are fitted, when the liquid sealing material is filled in the groove portion when the locking member is engaged in a state where the members are not released, the lid portion The lid does not float due to buoyancy. Thereby, the predetermined fitting state of a cover part and an accommodating part is maintained, and a favorable sealing state can be expected.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration of a sealed housing according to the present embodiment. As shown in FIG. 1A, a sealed housing 100 includes a storage portion 10 (one sealing member in the claims) in which a groove-type fitting portion 11 is formed, and a protruding fitting portion 21. Are formed, and a liquid sealing material 31 that changes its state from a liquid to a solid over time.

  In the sealed housing 100, the storage unit 10 and the lid unit 120 are fitted in a state in which the desired device 5 is stored inside the sealed housing 100. In addition, a liquid sealing material 31 is filled in a fitting gap formed by the groove-type fitting portion 11 and the protruding fitting portion 21 provided in these. Therefore, in the space formed between the storage portion 10 and the lid portion 120, exchange with outside air is not performed, so that a sealed space 4 that can prevent inflow and inflow of moisture, dust, and the like is formed. Further, since the predetermined device 5 is accommodated in the sealed space 4, the predetermined device 5 is also in a sealed state.

  FIG. 1B and FIG. 1C show a fitting state between the groove-type fitting portion 11 and the protruding fitting portion 21. In FIG. 1B, when the storage portion 10 and the lid portion 120 are fitted, the chamfered surface of the lid portion 120, the inner side surface 12 of the groove-type fitting portion, and an external fitting gap 71 described later. An outer groove 60 having a trapezoidal cross section is formed by the coupling surface 61 to be coupled. Further, an outer fitting gap 71 having a rectangular cross section is formed by the inner surface 12 in the groove-shaped fitting portion, the outer surface 22 in the protruding fitting portion, and the coupling surface 61 coupled to the outer groove 60. . Since the external groove 60 is coupled to the upper portion of the external fitting gap 71, the external groove 61 and the external fitting gap 71 form an integral groove via the interfacing virtual coupling surface 61. Yes.

  Further, in this embodiment, as shown in FIG. 1 (c), it is also possible to use the one in which the fitting state between the storage portion 10 and the lid portion 120 described in FIG. 1 (b) is further changed. . Specifically, the lid 120 is shifted by a predetermined amount in the direction of the external fitting gap 71 to form the above-described groove, while the inner surface 12 in the groove-shaped fitting portion and the protruding shape inside the lid 120. The inner surface 23 in the fitting portion is separated from the inner fitting gap 72, and an internal fitting gap 72 is newly generated. As a result, a gap is generated between both side surfaces of the protruding fitting portion 21 provided in the lid portion 20, so that the fitting state is relatively loose.

  In FIG. 2, the transition state of the liquid sealing material with which a sealing housing | casing is filled is shown. In this figure, the fitting layout in FIG. 1C is illustrated and described, but the fitting layout in FIG. 1B may be used. 2 (b) shows the opening width 62 in the cross section of the external groove 60, and the separation between the inner side surface 12 in the groove type fitting portion and the outer side surface 22 in the protruding type fitting portion. A width 63 is shown. In the present embodiment, since the cross-sectional shape of the external groove 60 formed in the lid portion 20 is a substantially triangular shape with the opening width 62 as a base, the cross-section of the external groove 60 has a separation width with the coupling surface 61 as a reference plane. It will increase continuously from 63 to the opening width 62.

First, FIG. 2A shows an initial state in which the liquid sealing material 31 is injected into the external groove 60. The liquid sealing material 31 filled in the external groove 60 is gradually lowered by its own weight. At this time, most of the liquid sealing material 31 is distributed in the vicinity of the external groove 60. Thereafter, as shown in FIG. 2B, the liquid sealing material 31 passes through the coupling surface 61 and is gradually sent from the external groove 60 to the external fitting gap 71. At this time, the liquid sealing material 31 is distributed in both the external groove 60 and the external fitting gap 71. Moreover, since the separation width 63 of the external fitting gap 71 is narrower than the cross-sectional width of the external groove 60, the liquid sealing material 31 is diffused to ensure a predetermined cross-sectional area, and the distribution state is more than before. spread. Thereafter, as shown in FIG. 2C, the liquid sealing material 31 further flows and diffuses downward, the distribution state further expands accordingly, and the region of the external fitting gap 71 is almost completely filled.

  In the present embodiment, since the external groove 60 is formed in the sealed casing 100 and the external groove 60 is laid out so as to expose the opening width 62 that is a wide groove width, the liquid sealing material 31 is provided. Can be easily injected. Since the external groove 60 is integrally coupled with the external fitting gap 71 having a relatively narrow groove width, the liquid sealing material 31 injected into the fitting groove 60 overflows outside the sealed housing 100. Instead, the external fitting gap 71 is filled and a good sealed state is obtained.

  Next, a modified example of the sealed housing according to the second embodiment will be described. In the configuration of the sealed casing 200 used in the present embodiment, the same portions as those of the sealed casing 100 are denoted by the same reference numerals and description thereof is omitted.

  With reference to FIG. 3A and FIG. 3B, in this embodiment, a new lid portion 220 is provided in place of the lid portion 120 described in the first embodiment. The lid 220 is formed with a rectangular cutout 92 in a state including the end of the protruding fitting portion 21. Accordingly, a tooth-shaped contour is formed on the end surface of the protruding fitting portion 21 by the notch 92.

With reference to the cross-sectional view of the fitting portion of FIG. 4A, a notch 92 is formed in the fitting state of the groove-type fitting portion 11 and the protruding fitting portion 21 according to this embodiment. The description will be divided into a non-CC section and a DD section in which the notch 92 is formed. First, in the case of the CC cross section, the cross section of the protruding fitting portion 21 according to the present embodiment has the same shape as the cross section of the protruding fitting portion 21 described in the first embodiment. For this reason, there is no difference in the fitting state in such a case. On the other hand, in the case of the DD cross section, the cross section of the protruding fitting portion 21 according to the present embodiment is different in shape from the cross section of the protruding fitting portion 21 described in the first embodiment. Specifically, when the storage portion 10 and the lid portion 220 are fitted, the external groove 60, the external fitting gap 71, and the internal fitting gap 72 are formed as described above. However, since the rectangular cutout portion 92 is formed in a state including the end portion of the protruding fitting portion 21, the external fitting gap 71 and the inner fitting gap 72 that are separated from each other are spatially connected. The communication path 82 to be made appears. Thereby, in the DD cross section, the cross section of the external groove 60 forms a substantially U-shaped groove in which the external fitting gap 71 and the internal fitting gap 72 are integrally coupled.

  Furthermore, in FIG. 4, the transition state of the liquid sealing material with which a sealing housing | casing is filled is shown. First, FIG. 4A shows an initial state in which the liquid sealing material 31 is injected into the external groove 60. The liquid sealing material 31 filled in the external groove 60 is gradually lowered by its own weight. At this time, most of the liquid sealing material 31 is distributed in the vicinity of the external groove 60. Thereafter, as shown in FIG. 4B, the liquid sealing material 31 passes through the coupling surface 61 and is gradually sent from the external groove 60 to the external fitting gap 71. At this time, since the cross section of the lid portion 220 in the CC cross section has the same shape as the cross section of the protruding fitting portion 21 of the lid portion 220, the behavior of the liquid sealing material 31 will be described in the first embodiment. The behavior of the liquid sealing material 31 is the same. At this time, when the liquid sealing material 31 flows, boundary friction is generated with an external wall surface, and the viscous resistance is received. Further, since the viscous resistance has a property that is inversely proportional to the separation distance between the wall surfaces, the flow rate of the liquid sealing material 31 is kept low in this case. Therefore, although the distribution state of the liquid sealing material 31 spreads within a predetermined range, it does not show a remarkable spread. On the other hand, in the cross section of the lid section 20 in the DD section, since the notch 92 is processed in the end 24 in the protruding fitting section, the liquid sealing material 31 that has passed through the virtual coupling surface 61 is the same as that described above. Similarly, the external fitting gap 71 flows at a low speed. However, since the liquid sealing material 31 after reaching the notch 92 flows in a space where the boundary surface is reduced and the width of the gap is widened, the viscous resistance is reduced, and the space near the notch 92 is reduced. It shows a remarkable spread at a high speed. As a result, as shown in the side view of the lid portion in FIG. 5B, a difference in flow state occurs between the CC cross section and the DD cross section, and the liquid sealing material 31 is grooved in the DD cross section. It can be observed that a region not filled with the liquid sealing material 31 remains in the CC cross section, while the lower portion of the fitting portion is substantially filled. Thereafter, as shown in FIG. 4C, the liquid sealing material 31 is efficiently replenished to the region not filled with the liquid sealing material 31 from both the upper portion of the region and the side portion on the side of the cutout portion 92. Thereby, the liquid sealing material 31 is efficiently filled in the entire region of the external fitting gap 71. Furthermore, the liquid sealing material 31 is also filled into the internal fitting gap 72.

In the present embodiment, since the notch 92 is provided in the protruding fitting portion 21 of the lid 30, the resistance to the liquid sealing material 31 is suppressed in the vicinity of the notch 92, and the resistance is low. Since the liquid sealing material 31 is sequentially supplied to the region, the liquid sealing material 31 can be efficiently filled into the external fitting gap 71. Further, the outer fitting gap 71 and the inner fitting gap 72 are communicated with each other by the notch 92, and the outer groove 60, the outer fitting gap 71, and the inner fitting gap 72 form a substantially U-shaped integral groove. Since the liquid sealing material 31 is formed, the liquid sealing material 31 is also filled in the internal fitting gap 72 to achieve a better sealed state.

As shown in FIG. 4D, for example, a rectangular concave processing portion 91 may be provided only on the outer surface of the protruding fitting portion 21. Also in this case, in the cross section in which the concave processing portion 91 is processed, the liquid sealing material 31 that has passed through the coupling surface 61 flows at a low speed through the external fitting gap 71 having a narrow width, and then the concave processing. Since the liquid sealing material 31 that has reached the portion 91 passes through the external fitting gap 71 having a wide groove width, it is efficiently filled in the external fitting gap 71 as described above. However, in this case, the liquid sealing material 31 is not filled into the internal fitting gap 72. Note that the processing shape of the concave processing portion 91 is not limited to the rectangular shape, and can be appropriately changed according to various conditions.

  Next, a further modification of the sealed housing according to the third embodiment will be described. Note that, in the configuration of the sealed casing 300 used in the present embodiment, the same portions as those of the sealed casing 100 are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 5A, even in this embodiment, a new lid 320 is replaced in place of the lid 120 described in the first embodiment. The lid 320 is provided with a protruding portion on the inner peripheral portion of the protruding fitting portion 21, and a lower portion of the protruding portion is in contact with the inner side wall of the groove-shaped fitting portion 11. A surface 81 is formed. In addition, the dimension of the distance X from the contact surface 81 to the end face in the projecting fitting portion 21 is designed to be shorter than the groove depth Y of the groove fitting portion 11.

  Next, the fitting state of the groove type fitting part 11 and the projecting type fitting part 21 according to the present embodiment will be described. As shown in FIG. 5B, when the storage portion 10 and the lid portion 320 are fitted, an external fitting gap is provided between the groove-type fitting portion 11 and the protruding fitting portion 21 as described above. 71 and an internal fitting gap 72 are formed. Further, when the projecting fitting part 21 is inserted into the groove of the grooved fitting part 11, the contact surface 81 has a grooved fitting part before the end 24 in the projecting fitting part. 11, the end 24 in the protruding fitting portion is not in contact with the bottom 13 in the groove fitting portion. Therefore, similarly to the description of the cutout portion of the second embodiment, a communication path 82 that spatially connects the external fitting gap 71 and the internal fitting gap 72 that are separated from each other appears. Thus, a substantially U-shaped groove in which the outer groove 60, the outer fitting gap 71, and the inner fitting gap 72 are integrally coupled is formed.

  FIGS. 5B to 5D show a transition state of the liquid sealing material filled in the sealed casing. First, FIG. 5B shows an initial state in which the liquid sealing material 31 is injected into the external groove 60. The liquid sealing material 31 filled in the external groove 60 is gradually lowered by its own weight. At this time, most of the liquid sealing material 31 is distributed in the vicinity of the external groove 60. Thereafter, as shown in FIG. 5C, the liquid sealing material 31 passes through the coupling surface 61 and is gradually fed from the external groove 60 to the external fitting gap 71 as described above. After that, the liquid sealing material 31 that has reached the end portion 24 in the projecting fitting portion flows through the communication passage 82 in which the width of the gap is widened, and thus flows in this space at a high speed. Thereafter, as shown in FIG. 5D, the liquid sealing material 31 is sequentially filled into the internal fitting gap 72.

In the present embodiment, since the distance of the external fitting gap 71 having a narrow width is designed to be short, the viscous resistance applied to the liquid sealing material 31 is suppressed, and the liquid sealing material 31 is efficient in each groove. It can flow well. Further, the external fitting gap 71 and the internal fitting gap 72 are communicated with each other by the communication passage 82, and the outer groove 60, the outer fitting gap 71, and the inner fitting gap 72 are formed into an integral U-shaped groove. Since the liquid sealing material 31 is formed, the liquid sealing material 31 is also filled in the internal fitting gap 72 to achieve a better sealed state.

Next, another embodiment of the sealed housing according to the fourth embodiment will be described. Note that, in the configuration of the sealed casing 400 used in the present embodiment, the same portions as those of the sealed casing 100 are denoted by the same reference numerals and description thereof is omitted.

  With reference to FIG. 6, the lid 420 is newly provided with a depressed gate 110 that appears outside the sealed housing 400. Further, the gate 110 is integrally connected to a part of the outer groove 60 in a hollow cross section.

  When supplying the liquid sealing material 31 over the entire circumference of the external groove 60 formed outside the sealing housing 400, first, the liquid sealing material 31 is poured into the gate 110. Thereafter, the liquid sealing material 31 poured into the gate 110 is led to the external groove 61 and flows on the side A of the external groove 60 in two hands. In the lower part of the external groove 60 to which the liquid sealing material 31 is supplied, the liquid sealing material 31 is sequentially filled into the external fitting gap 71 and the internal fitting gap 72 as described above. Thereafter, the liquid sealing material 31 reaches the side B of the outer groove 60 and flows while filling the liquid sealing material 31 sequentially into the lower fitting gap 71 and the inner fitting gap 72 by changing the flow direction. Further, the liquid sealing material 31 reaches the side C of the external groove 60, changes the flow direction, and joins with the other liquid sealing material 31 branched earlier near the middle point of the side C. As described above, the liquid sealing material 31 is supplied over the entire circumference of the outer groove 60, and the liquid sealing material 31 is sequentially filled into the fitting gap 71 and the inner fitting gap 72 below each outer groove 60. In FIG. 6, only one gate 110 is marked, but such gates may be appropriately provided at a plurality of locations as necessary. Moreover, the shape of the gate 110 can be changed as appropriate.

  In this embodiment, the position for supplying the liquid sealing material 31 is made uniform at a predetermined location by providing the gate 110, so that the liquid sealing material is formed over the entire circumference of the external groove 60 formed outside the sealing housing 400. When supplying 31, it is not necessary to move the spout of the liquid sealing material 31 along the external groove 60, and the injection operation of the liquid sealing material 31 is simplified.

Next, another embodiment of the sealed housing according to the fifth embodiment will be described. In the configuration of the sealed casing 500 used in the present embodiment, the same portions as those of the sealed casing 100 are denoted by the same reference numerals and description thereof is omitted.

  With reference to FIG. 7, first, the lid portion 520 is provided with an insertion hole 101 into which the locking member 100 is inserted. In addition, in the storage portion 510, the locking member 100 is assembled and the lid portion 520 and the storage portion 510 are fixed. An engaging portion 102 is provided.

  At the time of assembly of the lid part 520 and the storage part 510, after the lid part 520 and the storage part 510 are fitted together, both members are fixed by the locking member 103 in a state where the mutual fitting state is not removed. After that, as described above, the liquid sealing material 31 is filled in the external groove 60 formed outside the sealed casing 500. The locking member 103 described in the present embodiment is not limited to a bolt or a screw with a tap formed as shown in FIG. For example, a rivet may be used, or temporary fixing may be performed using an adhesive.

  In this embodiment, after the lid portion 510 and the storage portion 520 are fitted, the locking member 103 is engaged with each other in a state where the members are not released, so the liquid sealing material 31 is filled in the groove portion. In this case, buoyancy acts on the lid 20 and the lid 520 does not float. Thereby, the predetermined fitting state of the cover part 510 and the accommodating part 520 is maintained, and a favorable sealing state can be expected.

  In the first to fifth embodiments, as shown in FIG. 8, even if the liquid sealing material 31 is previously filled in the groove formed in the storage portion 610 and then the lid portion 620 is fitted, the sealed housing 600 can be sealed. The fitting state at this time is the same as the fitting state described in the first embodiment.

  However, the sealing process at that time is performed as shown in FIGS. 9A to 9B. First, FIG. 9A shows a state where the liquid sealing material 31 is filled. Thereafter, as shown in FIG. 9B, when the cover 620 starts to be fitted into the storage portion 610, the protruding fitting portion 21 is inserted into the groove-type fitting portion 11, and the liquid sealing material 31. Begins to be divided into an outer region and an inner region of the protruding fitting 21. At this time, the liquid sealing material 31 in each region gradually spreads upward. Thereafter, when the fitting operation proceeds, the respective regions are completely isolated, and the external fitting gap 71 and the internal fitting gap 72 appear. At this time, the liquid sealing material 31 in each region gradually spreads upward, and the surplus portion of the liquid sealing material 31 in the region of the external fitting gap 71 reaches the external groove 60. At this time, it is possible to prevent the excess liquid sealing material 60 from overflowing from the external groove 60 by calculating the surplus of the liquid sealing material 31 in advance and determining the dimensions of the cross-sectional shape of the external groove 60. It becomes.

  Each embodiment described as above is only one embodiment of the present invention, and the meaning of the terminology of the present invention or each constituent element is not limited to that described in the embodiment. Absent. In the present embodiment, the acrylic plate 14 is provided in the storage unit 10 so that the inside of the sealed housing 100 can be observed. However, without providing the acrylic plate 14, the inside of the sealed housing 100 is not visible. Also good. Further, in this embodiment, all parts of the predetermined device 5 are stored inside the sealed housing. However, a portion of the predetermined device 5 that does not require sealing is exposed to the outside. If the design can be changed, and the predetermined device 5 is a device that requires a power source, an opening that can maintain a sealed state is provided to supply power to the predetermined device 5 through the power line. Also good. Further, an operation button or the like corresponding to the device related to the outside of the sealed housing may be provided so that the predetermined device 5 can be operated from the outside of the sealed housing. Furthermore, as the liquid sealing material used in the present invention, UV resin, epoxy resin, and other various resin materials are used.
