Description

  The present invention relates to a case coupling structure for a case in which information devices such as KIOSK terminals, various game devices for halls, and the like are superposed and placed on top and bottom.

  For example, as disclosed in Patent Document 1, a gaming machine in which an upper unit and a lower unit are fixed as an example of a case structure in which upper and lower cases placed on each other are fixed and integrated. Is known.

In addition, as a specific coupling structure, a notch portion formed of a slope and a flat bottom surface is formed on the chassis, and the electric device placed on the chassis is moved in the front-rear direction to cut the caster of the electric device. The electrical equipment is prevented from being displaced in the horizontal plane by being dropped into the horizontal plane, and the electrical equipment is sandwiched between the chassis and the projection fixed to the chassis support frame according to the height of the electrical equipment. Patent Document 2 proposes a storage mechanism that prevents vertical displacement and vibration of the device.
However, in the storage mechanism disclosed in Patent Document 2, after the electric device is placed on the chassis using a forklift or a lifter, the caster is moved by moving the electric device in the front-rear direction using the caster of the electric device. It is configured to drop into the notch on the chassis, and no consideration is given to the problem that occurs when manually stacking electrical equipment, that is, the problem of sandwiching your hand between the bottom of the electrical equipment and the chassis. Not.
In addition, the vertical displacement and vibration can be eliminated by pressing the upper surface of the electrical equipment using the protrusions fixed on the side of the support frame. In short, the electrical equipment is placed inside the support frame. It is a structure based on the above, and is unsuitable for applications such as a case in which a casing that is an exterior body is overlapped and fixed on another casing (there is no support frame, and there is no (There is no place to provide a protrusion to hold down the upper surface of the housing.)

Further, as another coupling structure, the peripheral frame and the peripheral frame can be fitted by engaging the engaging protrusions on the surface of the side wall panel with the engaging grooves formed obliquely through the upper end edge of the peripheral frame made of a rectangular frame. An assembly-type container in which the side wall panel is fixed is disclosed as Patent Document 3.
In this assembly type container, the lower end edge of the side wall panel has already passed the upper end edge of the peripheral frame at the stage where the engaging projection protruding from the surface of the side wall panel enters the entrance of the engaging groove of the peripheral frame. In this structure, the lower end of the upper member and the upper end of the lower member overlap in a vertical plane without any mechanical support. is there. Such a structure seems to have no particular problem with respect to the assembly work of a lightweight object such as a side wall panel of a container. However, a similar structure to this structure has a large weight, for example, an information device such as a KIOSK terminal. When the upper case is placed on the lower case by placing a hand on the lower surface of the upper case, the upper case (on the side panel) It is conceivable that there is a problem that a finger is accidentally sandwiched between the lower housing (equivalent to the peripheral frame).

  As a means for solving such problems, a handle protruding outward is attached to the side surface of the upper housing, or a concave portion is formed on the outer peripheral portion of the contact surface of the upper housing or the lower housing. However, in any case, there is a detrimental effect that a design problem such as impairing the sense of unity of the combined upper and lower casings occurs.

Japanese Patent Laying-Open No. 2004-267695 (FIG. 3) Japanese Patent Laying-Open No. 2004-235177 (FIG. 8) Japanese Patent Laying-Open No. 2006-69575 (FIG. 2)

  Therefore, the problem of the present invention is that there is no risk of inadvertently pinching a finger or the like even if the hand is lifted with the hand held on the lower surface of the upper housing and placed on the lower housing. An object of the present invention is to provide a housing coupling structure that can effectively suppress a positional deviation and vibration in a direction and has no problem in appearance.

The housing coupling structure of the present invention is a housing coupling structure for fixing an upper housing and a lower housing that are stacked and placed one above the other, and in order to achieve the above-mentioned problem,
A protrusion having a rectangular cross section is formed on one surface of the lower surface of the upper housing or the upper surface of the lower housing, while a groove is formed on the other surface to fit with the protrusions.
Two or more protrusions projecting from the upper end portion of the inner surface toward the inner surface facing the inner surface are spaced apart in the longitudinal direction of the groove, and the width of the groove Two or more sets are fixed at intervals in the direction,
The outer surface of the ridge has a cross-sectional shape circumscribing the protrusion, and is inclined with respect to the end surface in the protruding direction of the ridge in a direction from the end surface of the protruding direction toward the base of the ridge. A protrusion fitting path extending along the longitudinal direction of the protrusion is formed in one-to-one correspondence with the fixed position of each protrusion.

According to the case coupling structure of the present invention, even if the case is placed on the lower case with the hand held on the lower surface of the upper case, there is no gap between the lower surface of the upper case and the upper surface of the lower case. There is no need to worry about your fingers being caught.
This eliminates the need for additional items such as a handle, and enhances the sense of unity between the combined upper and lower housings.
In addition, in the state where the upper housing and the lower housing are combined, the protrusion on the inner surface of the groove is sandwiched from above and below by the protrusion fitting path on the outer surface of the ridge, so the vertical direction of the upper housing It is also possible to effectively suppress positional deviation and vibration.

  Next, an example is given about the best form for implementing this invention, and it demonstrates in detail with reference to drawings.

  FIG. 1 shows an information device according to an embodiment to which the case coupling structure of the present invention is applied, specifically, an upper case 1 in which a monitor or the like is mounted, an input operation unit, a control unit, a power supply unit, etc. (not shown). It is the perspective view which simplified and showed the external appearance of the KIOSK terminal 3 comprised by the mounted lower housing | casing 2. FIG. FIG. 2 is a perspective view showing the upper half 4a of the case coupling structure 4 in the present embodiment in the form of looking up the upper case 1 removed from the lower case 2, and FIG. It is the perspective view which showed the lower half 4b of the housing | casing coupling | bonding structure 4 of this embodiment in the form which looked down at the lower housing | casing 2 from which it removed.

  In the present embodiment, a rectangular cross section is formed on the lower surface 1a of the upper housing 1 which is one of the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2 as shown in FIG. Two pairs of protrusions 5 and 5 are formed in parallel with a gap in the width direction, and on the upper surface 2a side of the lower housing 2 which is the other surface, as shown in FIG. Two sets of grooves 6 and 6 for engaging with the protrusions 5 and 5 are integrally formed at intervals in the width direction as described above.

As shown in FIG. 3, the inner surface 6a of each groove 6 constituting the main part of the lower half 4b of the housing coupling structure 4 is opposed to the inner surface 6a from the upper end of the inner surface 6a. Two protrusions 7 projecting toward the inner side surface 6b are fixed at intervals in the longitudinal direction of the groove 6.
In this embodiment, there are two sets of grooves 6, and the two protrusions 7 and 7 are fixed on the inner surfaces 6 a and 6 a of the grooves 6 and 6. As a result, the grooves 6 are spaced apart in the longitudinal direction. One set of protrusions 7, 7 fixed is spaced apart in the width direction of the groove 6, that is, four protrusions 7 are fixed to the grooves 6, 6 together.

Here, an example in which two protrusions 7 and 7 are provided on the inner surface 6a of each groove 6 is shown, but two protrusions 7 and 7 may be provided on the inner surface 6b side of each groove 6. .
Alternatively, two protrusions 7 and 7 are dispersed on the inner side surface 6a and the inner side surface 6b of each groove 6 so that one protrusion 7 is provided on each of the inner side surface 6a and the inner side surface 6b. The number of 7 may be two.
Further, a combination thereof, that is, in one groove 6, two protrusions 7 and 7 are provided on either the inner surface 6 a or the inner surface 6 b, while in the other groove 6, the inner surface 6 a of the groove 6. Alternatively, one protrusion 7 may be provided on the inner surface 6b, and the number of protrusions 7 per groove 6 may be two.
In particular, in the case where the weight of the upper housing 1 is extremely heavy, two protrusions 7 and 7 are provided on both inner side surfaces 6a and 6b of each groove 6, and the protrusions for each groove 6 are provided. The number of 7 may be four.

  On the other hand, on the outer surfaces 5a and 5a of the ridges 5 and 5 that fit into the grooves 6 and 6, as shown in FIG. 2, the protrusion fitting paths 8 and 8 that engage with the protrusions 7 and 7 of the groove 6, respectively. Is formed.

  Here, the configuration of the protrusion fitting path 8 provided in the protrusions 5 and 5 constituting the main part of the upper half 4a of the housing coupling structure 4 will be described in detail.

  FIG. 4 is a front view of the upper housing 1 shown with the monitor mounting surface of the upper housing 1 facing forward, and FIG. 5A is an upper housing 1 showing the section AA in FIG. FIG. FIG. 5B is a partially enlarged view showing the region B in FIG. 5A including one of the protrusion fitting paths 8 in an enlarged manner.

As shown in FIGS. 2 and 5 (b), each projection fitting path 8 is inclined at an angle of about 30 ° with respect to the end surface 5b in the protruding direction of the ridge 5 in an end surface 5b. It is formed to extend along the longitudinal direction of the ridge 5 in a direction from the ridge 5 toward the base 5 c of the ridge 5.
That is, when the projection fitting path 8 is viewed from the direction of the arrow AA in FIG. 4 as shown in FIG. 5A or 5B, it is 30 with respect to the end surface 5b in the protruding direction of the protrusion 5. A projection fitting path 8 is formed in a direction from the end surface 5b toward the base portion 5c of the protrusion 5 at an inclination angle of about front and rear, and the projection fitting from the lower surface side of the upper housing 1 as shown in FIG. Looking at the path 8, the protrusion fitting path 8 is formed so that the direction in which the protrusion fitting path 8 extends coincides with the longitudinal direction of the protrusion 5.

  Furthermore, in this embodiment, as shown in FIG. 5 (b), the protrusion fixing path 9 extending along the longitudinal direction of the protrusion 5 in a shape parallel to the end surface 5b in the protrusion direction of the protrusion 5, It is connected to the protrusion fitting path 8 and is formed on the base portion 5 c of the protrusion 5. Moreover, the positioning recessed part 10 which has the bottom area which accept | permitted mounting | wearing of the protrusion 7 by the side of the groove | channel 6 is shown in FIG. 2 and FIG. Thus, it is formed so as to communicate with the opening of the protrusion fitting path 8 on the extension line of the protrusion fitting path 8.

Both the protrusion fitting path 8 and the protrusion fixing path 9 have a cross-sectional shape circumscribing the protrusion 7 on the groove 6 side. For example, as shown in FIG. 6, the fixed positions of the protrusions 7 on the groove 6 side are provided. Are provided in a one-to-one correspondence.
In FIG. 5B, the groove dimensions of the protrusion fitting path 8 and the protrusion fixing path 9 are different because the cross-sectional shape of the protrusion 7 of this embodiment is rectangular. In the section of the protrusion fitting path 8 that is oblique to the protrusion, the corner of the outer peripheral surface of the protrusion 7 is in sliding contact with the protrusion fitting path 8, and the protrusion is parallel to the end face 5b of the protrusion 5 in the protruding direction. This is because the upper and lower surfaces of the outer peripheral surface of the protrusion 7 are in sliding contact with the protrusion fixing path 9 in the section of the fixing path 9. When the protrusion 7 is formed in a columnar shape, the groove dimensions of the protrusion fitting path 8 and the protrusion fixing path 9 may be equal.

  2, FIG. 5A and FIG. 5B, the protrusion fitting path 8 and the protrusion fixing path correspond to the configuration example of FIG. 3 in which two protrusions 7 are provided on the inner surface 6a of the groove 6. 9 is shown, but when two protrusions 7 are provided on the inner surface 6b side of each groove 6 shown in FIG. 5 and 5, the protrusion fitting path 8 and the protrusion fixing path 9 are formed on the outer surfaces 5 d and 5 d, and the two protrusions 7 and 7 are dispersed on the inner surface 6 a and the inner surface 6 b of each groove 6. When one projection 7 is provided on each of the inner side surface 6a and the inner side surface 6b, one projection fitting path 8 is provided on each of the outer side surfaces 5a and 5d of the ridges 5 and 5 fitted in the grooves 6 and 6. , The protrusion fixing path 9 is formed.

  Next, a procedure for mounting and fixing the upper housing 1 to the lower housing 2 will be described with reference to FIG.

First, a portion of the lower surface 1a of the upper housing 1 shown in FIG. 2 where the ridges 5 and 5 are not formed, that is, the portions of the lower surfaces 1a on both the left and right sides outside the ridges 5 and 5 is placed. Then, the upper casing 1 is lifted, and the positions of the protrusions 5 and 5 of the upper casing 1 are adjusted to the positions of the grooves 6 and 6 on the lower casing 2 side.
Alternatively, the upper housing 1 may be lifted by placing a hand on the central portion of the lower surface 1a inside the ridges 5 and 5.

  Then, as shown in FIG. 6, the upper housing 1 is slightly shifted to the front side of the lower housing 2 and protrudes to the positions of the protrusions 7, 7 protruding from the inner surfaces 6 a, 6 a of the grooves 6, 6. The upper housing 1 is placed on the lower housing 2 so that the positioning recesses 10 and 10 on the end surfaces 5b of the strips 5 and 5 are aligned.

  In this state, as shown in FIG. 6, the protrusions 7 and 7 on the inner surfaces 6a and 6a of the grooves 6 and 6 are in contact with the positioning recesses 10 and 10 on the end surface 5b in the protruding direction of the protrusions 5 and 5. Since the upper housing 1 is supported in contact with each other, a gap equivalent to the height H of the protrusions 5 and 5 is formed between the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2. . The size of the gap H is suitably a size that is slightly larger than the diameter of the finger, for example, about 25 mm.

  More specifically, the gap H is formed on both the left and right sides of the lower surface 1a of the upper housing 1 and the central portion of the lower surface 1a on the inner side of the ridges 5 and 5, that is, the upper housing 1 is located on the lower side. This is a portion that is handed when placed on the housing 2.

  Therefore, even if the upper casing 1 is placed on the lower casing 2 while holding the hand on the lower surface 1a of the upper casing 1, the lower surface 1a of the upper casing 1 and the upper surface 2a of the lower casing 2 are not affected. There is no worry that a finger or the like is inadvertently sandwiched between them, and the upper housing 1 can be safely placed on the lower housing 2.

  Further, when it is difficult to align the positioning recesses 10 and 10 with the positions of the protrusions 7 and 7, for example, as shown in FIGS. 3 and 2, the protrusions 7 are formed on the inner side surfaces 6a and 6a of the groove 6. , 7, and projection fitting paths 8, 8 are formed on the outer surfaces 5 a, 5 a of the ridges 5, 5 in accordance therewith, and the positioning recess 10 is formed from the left and right side surfaces of the upper housing 1. , 10 and the positions of the projections 7 and 7 are seals that indicate the positions of the projections 7 and the positioning recesses 10 on the side surface of the lower housing 2 and the side surface of the upper housing 1 in advance. It is preferable that the markings 11 and 12 are pasted in advance as shown in FIG.

  In this embodiment, since the positioning recess 10 is provided so as to communicate with the opening of the projection fitting path 8 on the extension line of the projection fitting path 8, a blind groping operation is performed. In addition, it is possible to relatively easily perform the positioning operation when placing the upper housing 1 on the lower housing 2, that is, the operation of positioning the vicinity of the entrance of the protrusion fitting path 8 on the protrusion 7. .

  Next, when the hand hung on the lower surface 1a of the upper casing 1 is removed and the upper casing 1 is pushed rearward, that is, from the right to the left in the state shown in FIG. Slip occurs between the recesses 10 and 10 and the projections 7 and 7 of the grooves 6 and 6, and the upper housing 1 moves in the direction from right to left in FIG. The protrusions 7 and 7 enter the protrusion fitting paths 8 and 8 of the protrusions 5 and 5.

  In FIG. 6, the lower surface 1 a of the upper housing 1 faces the upper surface 2 a of the lower housing 2 in accordance with the amount of horizontal movement of the upper housing 1 from right to left and the inclination of the protrusion fitting path 8. When approaching the right end of the protrusion fitting path 8 that moves while being gradually guided and finally guided by the protrusion 7, that is, the direction of the upper housing 1, the front of the protrusion fitting path 8 is used. When the end on the side reaches the position of the protrusion 7, the gap H between the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2 is eliminated, and the lower surface 1a of the upper housing 1 and the lower portion The upper surface 2a of the housing 2 and the end surface 5b in the projecting direction of the protrusion 5 and the bottom surface of the groove 6 are completely adhered.

  Thereafter, when the upper casing 1 is further moved from the front toward the rear, the right end portion of the protrusion fixing path 9 connected to the protrusion fitting path 8 finally hits the protrusion 7, and for example, as shown in FIG. In this way, the lower surface 1 a of the upper housing 1 is completely overlapped with the upper surface 2 a of the lower housing 2.

In this state, the protrusions 7 and 7 of the grooves 6 and 6 are sandwiched from above and below by the protrusion fixing paths 9 and 9 on the outer side surfaces 5a and 5a of the protrusions 5 and 5, so The vertical displacement and vibration of the upper housing 1 can be effectively suppressed, and the horizontal displacement and vibration of the upper housing 1 relative to the lower housing 2 are also caused by the grooves 6 and 6 and the protrusions. It can prevent reliably by 5 and 5 fitting.
In particular, in this embodiment, the protrusions 7 and 7 of the grooves 6 and 6 are vertically moved by the protrusion fixing path 9 extending along the longitudinal direction of the protrusion 5 in a shape parallel to the end surface 5b of the protrusion 5 in the protruding direction. Since the upper housing 1 is rocked and slightly displaced in the front-rear direction, the lower surface 1a of the upper housing 1 is in close contact with the upper surface 2a of the lower housing 2. This is superior to the configuration in which the upper housing 1 and the lower housing 2 are fixed using only the protrusion fitting path 8.
Further, of the positional displacement and vibration in the front-rear direction of the upper housing 1 with respect to the lower housing 2, the positional displacement and vibration in the direction in which the upper housing 1 moves rearward are projected on the wall surface 6 c on the rear side in the longitudinal direction of the groove 6. Although it is prevented by contact with the end surface 5e on the rear side in the longitudinal direction of the strip 5, it is particularly the length of the protrusion fixing path 9 that suppresses displacement and vibration in the direction in which the upper housing 1 moves forward. Is difficult in a situation where the width of the projection 7 is longer than the front and rear width of the projection 7. For example, as shown in FIG. 1, a screw 13 such as a hexagon socket set screw is screwed onto the side surface of the lower housing 2. The outer surface 5d of the protrusion 5 of the upper housing 1 may be fixed at the tip. For example, as shown in FIG. 2, a blind hole 14 that allows the tip of the screw 13 to enter is formed in the outer surface 5 d of the protrusion 5.
Even if there is carelessness such as forgetting to stop the screw 13, as described above, the upper housing 1 is fixed to the lower housing 2 by fitting the protrusions 7, 7 and the protrusion fixing paths 9, 9. The upper housing 1 is securely fixed in the left-right direction with respect to the lower housing 2 by fitting the grooves 6 and 6 with the protrusions 5 and 5, so that an earthquake, etc. Even if the KIOSK terminal 3 is strongly shaken under these extreme conditions, there is no fear that the upper casing 1 is easily detached from the lower casing 2 and jumps out.

When removing the upper housing 1 from the lower housing 2, contrary to the above, the screw 13 is loosened and then the upper housing 1 is pulled out.
In this embodiment, since the positioning recess 10 is provided on the end surface 5b side of the protrusion 5 so as to communicate with the opening of the protrusion fitting path 8 on the extension line of the protrusion fitting path 8, the upper housing When 1 is pulled forward and the protrusion fitting path 8 is detached from the protrusion 7, the edge of the positioning recess 10 is caught by the protrusion 7 and the movement of the upper housing 1 is stopped.
By this catching, it is possible to easily confirm that the projection fitting path 8 has been detached from the projection 7, so that it is possible to prevent failures such as, for example, pulling the upper housing 1 forward and dropping it on the feet. Can do.

  In this embodiment, since the protrusion fixing path 9 connected to the protrusion fitting path 8 is provided, as described above, first, when the front end of the protrusion fitting path 8 reaches the position of the protrusion 7. The gap H between the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2 is eliminated, and the upper housing 1 is moved further by a distance corresponding to the length of the protrusion fixing path 9 after that. The lower surface 1a of the housing 1 completely overlaps with the upper surface 2a of the lower housing 2, but when the protrusion fixing path 9 is omitted and only the protrusion fitting path 8 is formed, the protrusion fitting path 8 The gap H between the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2 is eliminated at the time when the end on the front side of the upper housing 1 abuts against the protrusion 7, and at the same time, the lower surface 1a of the upper housing 1 The inclination and length of the protrusion fitting path 8 are designed so as to completely overlap with the upper surface 2a of the housing 2. So as to.

Here, as an example, a case where two sets of protrusions 5 and 5 are formed on the lower surface 1a of the upper housing 1 and two sets of grooves 6 and 6 are formed on the upper surface 2a of the lower housing 2 has been described. Conversely, two sets of grooves 6 and 6 may be formed on the lower surface 1 a of the upper housing 1, and two sets of protrusions 5 and 5 may be formed on the upper surface 2 a of the lower housing 2.
However, since information devices such as the KIOSK terminal 3 are normally installed with the back side facing the wall, when the grooves 6 and 6 are formed on the lower surface 1a of the upper case 1, the upper case It is necessary to push the protrusions 7 and 7 of the grooves 6 and 6 into the protrusion fitting paths 8 and 8 of the ridges 5 and 5 by pushing 1 backward from the front side. Therefore, the protrusion fitting path 8 on the ridge 5 side extends from the near side toward the rear, and the protrusion fixing path 9 is connected to the rear end of the protrusion fixing path 9.
The configuration in this case is the same as the configuration in the case where FIG. 6 is rotated 180 ° in the horizontal plane and the upper casing 1 is replaced with the lower casing 2 and the lower casing 2 is replaced with the upper casing 1.

  Of course, the ridges 5 and the grooves 6 are not limited to two, but can be provided over three or more sets. Also, the ridges 5 and the grooves 6 are formed in the left-right direction, and the upper housing 1 is formed in the left-right direction. It may be configured to be attached to the lower housing 2 in such a manner that it is slid.

  Further, the protrusion 7 of the groove 6 may be formed in a bridge shape that communicates from one inner side surface 6a to the opposing inner side surface 6b. In this case, the protrusion fitting path 8 and the protrusion fixing path 9 are also formed so as to completely penetrate the outer surface 5d from the outer surface 5a of the protrusion 5 in accordance with the shape of the protrusion 7.

Further, only one protrusion is formed on the lower surface 1 a of the upper housing 1, and only one groove is formed on the upper surface 2 a of the lower housing 2, so that the upper housing 2 is fixed to the lower housing 2. In some cases, a configuration is used.
In that case, for example, only one wide protrusion having a lateral width comparable to the distance between the outer surfaces 5d and 5d of the two protrusions 5 and 5 shown in FIG. 2 is formed on the lower surface 1a of the upper housing 1. Only one wide groove is formed on the upper surface 2a side of the lower housing 2 so as to be fitted to this protrusion.
Further, two protrusions 7 and 7 are provided on each of the left and right inner surfaces of the groove with a gap in the longitudinal direction of the groove, and in correspondence with this, one wide protrusion is formed. Two sets of protrusion fitting paths 8 and protrusion fixing paths 9 are provided on each of the left and right outer surfaces.
Even when such a configuration is applied, the procedure for installing the upper casing 1 on the lower casing 2 and the overall operation and effects will be described with reference to FIGS. This is the same as in the above-described embodiment.

Even if any of the configurations described above is applied, the position of the protrusion formed on one surface of the lower surface 1a of the upper housing 1 or the upper surface 2a of the lower housing 2 and the other surface In a state where the upper housing 1 is placed on the lower housing 2 so as to match the position of the formed groove, the protrusion on the inner surface of the groove contacts the end surface in the protruding direction of the protrusion, and the upper housing By supporting the body 1, a gap H comparable to the height of the ridge is formed between the lower surface 1 a of the upper housing 1 and the upper surface 2 a of the lower housing 2. Even if it is placed on the lower housing 2 with its hand held, there is a disadvantage that a finger or the like is inadvertently sandwiched between the lower surface 1a of the upper housing 1 and the upper surface 2a of the lower housing 2. Can be prevented.
Further, when the upper housing 1 is slid along the longitudinal direction of the groove or the ridge while the upper housing 1 is placed on the lower housing 2, the protrusion on the inner surface of the groove is projected. The lower surface 1a of the upper housing 1 gradually approaches the upper surface 2a of the lower housing 2 according to the amount of movement and the inclination of the protrusion fitting route. In addition, when the projection that moves relatively along the projection fitting path reaches the end of the projection fitting path, the gap H between the lower surface of the upper housing and the upper surface of the lower housing is eliminated, The lower surface 1a of the upper housing 1 completely overlaps with the upper surface 2a of the lower housing 2 (when the protrusion fixing path is formed, the protrusion reaches the end of the protrusion fixing path). In this state, the protrusion on the inner surface of the groove is sandwiched from above and below by the protrusion fitting path or the protrusion fixing path (when the protrusion fixing path is formed) on the outer surface of the protrusion. It is also possible to effectively suppress vertical displacement and vibration.
There is no worry that a finger or the like is inadvertently sandwiched between the upper housing 1 and the lower housing 2, and there is no need to attach an additional object such as a handle to the upper housing 1. The sense of unity when 2 are combined is increased.
