A mode for carrying out the invention is shown below. As can be seen from FIGS. 1 to 4, the cabinet 1 of the present embodiment includes a metal housing and a metal mounting member that is joined to the housing to provide additional functions. , Is equipped. In addition, this mounting member includes a joint piece to be joined to the housing, and also has a functional piece that exerts an additional function at a portion erected from the joint piece, and the joint piece and the housing are joined by a mechanical clinch. ing. Therefore, the three-dimensional mounting member can be easily mounted on the housing of the cabinet 1. In particular, it is not necessary to perform welding or drilling when joining the mounting member and the housing, and workability can be improved. A joint portion 80 is formed at a portion where the joint is made by mechanical clinching.

The housing of the cabinet 1 may mean only the housing main body 10 in addition to the case where the housing including the housing main body 10 and the door 11 is included.

Here, a mounting member that functions as a light-shielding plate will be described as an example. The cabinet 1 of the example shown in FIGS. 1 to 4 has a mounting member that protects (light-shields) the ceiling surface of the housing and protects the side surface of the housing (as shown in FIGS. 2 and 3). It is equipped with a mounting member that shields light from light. These mounting members are light-shielding plates that are joined to the outside of the housing, and the joint pieces are attached to the outer shell of the housing so as to form a space S between the functional piece that exerts the light-shielding function and the housing. And are joined. With such a configuration, the light-shielding plate can be easily attached to the housing.

In the examples shown in FIGS. 1 to 4, the mounting member that protects the ceiling surface of the housing and the mounting member that protects the side surface of the housing are caulked and joined to the side surface of the housing body 10 by mechanical clinching. .. In this example, the left and right ends of the functional piece 212 (light-shielding portion) of the first mounting member that shields the ceiling surface so that both mounting members can be joined to the side surface of the housing body 10 by mechanical clinching. A joint piece 211 extending substantially vertically downward from the portion is provided. This mounting member is provided with a portion that becomes a joint piece 211 and a portion that becomes a functional piece 212 by bending a plate-shaped member. The joint piece 211 is a portion extending substantially vertically downward on the left and right sides of the housing, and the functional piece 212 is a portion extending horizontally above the housing.

Further, in the example shown in FIG. 1 and the like, a second mounting member that shields the side surface from light is provided, and this second mounting member extends substantially horizontally from the upper and lower ends of the functional piece 222 (light-shielding portion). It is formed so as to provide a portion and a joint piece 221 extending in the vertical direction from the end portion thereof. These portions are formed by bending a plate-shaped member so as to form a so-called hat cross section. In a state where the second mounting member is joined to the housing, the joining piece 221 is a portion extending substantially vertically at a position adjacent to the housing, and the functional piece 222 is substantially separated from the housing. It is a part that extends in the vertical direction.

In the examples shown in FIGS. 1 to 4, the joint piece 211 of the first mounting member extends to the side surface of the housing body 10, and both the housing body 10 and the joint piece 221 of the second mounting member are mechanically clinched. It is caulked and joined by a ring. Therefore, the joining position and joining work can be standardized. In the example shown in FIG. 3, the second mounting member (side light-shielding plate) and the first mounting member (ceiling surface light-shielding plate) are joined in this order by stacking the joining pieces on the side surface of the housing. .. In the example shown in FIG. 3, the first mounting member and the second mounting member are crimped to the housing by a common joint 80, but the first mounting member and the second mounting member are different from each other. The structure may be crimped to the side surface of the housing at a location.

In this way, the first mounting member that serves as the first light-shielding plate that protects the first surface of the housing and the second mounting member that serves as the second light-shielding plate that protects the surface different from the first surface are If the joint piece 211 of the first mounting member is extended to the surface to which the joint piece 221 of the second mounting member is mounted, the joint surface can be shared, so that the direction of the joint is changed. Is constant, and the joining workability is improved. Further, if the joint piece 211 of the first mounting member, the joint piece 221 of the second mounting member, and the portion where the surfaces constituting the housing overlap are caulked and joined by mechanical clinching, the work is further performed. It is possible to save the trouble of.

Further, the joint piece of the first mounting member and the second mounting member is formed at a position where the joint piece is exposed from the functional piece. Therefore, even if it is a three-dimensional light-shielding plate, it is not necessary to form a "hole 82 for inserting a joining tool" as provided in an example described later. For this reason, it is easy to manufacture and does not spoil the aesthetic appearance.

By the way, in mechanical clinching, two thin plates crimped between a punch (male) and a die (female) are mechanically joined so as to bite into the other party. Due to such a configuration, the mechanical clinching is weaker in the peeling direction than in the shearing direction. This point can be improved by mounting the mounting member so that a part of the housing is sandwiched between the two joining pieces 211 provided on the mounting member.

For example, as can be seen from FIG. 2, the first mounting member that functions as a light-shielding plate is formed so that the joining pieces 211 face each other. The mounting member is mounted on the housing so that a ceiling plate or the like (a part of the housing) is sandwiched between the two joint pieces 211 provided on the mounting member. At this time, mechanical clinching is performed. The caulking deformation is performed so that unevenness is formed in the left-right direction. Since the movement of the first mounting member in the left-right direction is restricted by the positional relationship between the joint piece 211 and the ceiling plate, the movement in the peeling direction is restricted to the joint portion 80 where mechanical clinching is performed. On the other hand, it is suppressed that a large force is applied in the peeling direction. Therefore, the mounting strength in the vertical and horizontal directions can be increased.

By the way, in the examples shown in FIGS. 1 to 4, the first mounting member that functions as a light-shielding plate on the ceiling surface has a substantially U-shaped cross section, and the second mounting member that functions as a side light-shielding plate. The member has a so-called hat cross section by providing joint pieces 221 at both ends of a portion having a convex cross section, and each of the members is joined on the side surface of the housing body 10. On the other hand, when the first mounting member and the second mounting member are mounted on the ceiling surface, the first mounting member has a cross section of a hat and the second mounting member has a substantially U-shaped step surface. It should be.

If the examples shown in FIGS. 1 to 4 are used, it is not necessary to make a hole in the housing, so that there is no risk of water entering the housing. If a hole is made in the housing, rust may occur from the cut surface, but if joining by mechanical clinching is used, there is no possibility of rusting.

Next, another example of a mounting member that functions as a light-shielding plate will be described. In the examples shown in FIGS. 5 to 7, the first mounting member that shields the ceiling surface is joined to the ceiling surface by mechanical clinching, and the second mounting member that shields the left and right sides is mechanically connected to the left and right sides. It is joined using clinching. Further, a mounting member that shields the front surface from light is joined to the door 11 by using mechanical clinching. Each joint piece is provided so as to extend inside the mounting member. Specifically, the joint piece 231 is provided so as to extend by bending at a substantially right angle from the end portion of the bent piece provided so as to rise from both ends of the functional piece 232 that functions as a light-shielding portion, and has a substantially C-shaped cross section. I try to make it look like. Therefore, the joint piece 231 joined to the housing is covered with the functional piece 232.

If the functional piece 232 and the joint piece 231 have such a positional relationship, it becomes difficult to provide the joint portion 80 that crimps the housing and the joint piece 231. Therefore, in the embodiment, a joining tool is attached to the functional piece 232. A hole 82 that can be inserted is provided. The hole 82 will be located at a location facing the joint 80 created by the caulking connection. In this way, the joint piece 231 provided at a position facing the functional piece 232 and the surface protected by the functional piece 232 are connected by the joint portion 80, and the functional piece 232 is attached to the joining tool. If the hole 82 into which the wire is inserted is provided at a position facing the joint 80, the mounting member serving as a light-shielding member can be joined to the housing without the need for major modification of the housing side. Further, even if such a hole 82 is provided, the presence of the functional piece 232 makes it difficult for the joint 80 to be visually recognized or accessed from the outside. Since the entire surface protected by the functional piece 232 can be covered with the functional piece 232, it is possible to make the light-shielding area wider than the examples shown in FIGS. 1 to 4.

By the way, when the fan 91 is provided between the functional piece 232 and the housing body 10, if the fan 91 is arranged at a position facing the hole 82 as in the example shown in FIG. 8, the hole 82 can be ventilated. It can be used. In that case, it is preferable that the fan 91 is provided with the louver 92. It is preferable to mount the fan 91 at a position where the ventilation hole does not overlap with the joint piece 231. In this way, if the fan 91 is provided between the functional piece 232 and the housing and the hole 82 is located at a position facing the fan 91, the hole 82 also functions as a ventilation hole for ventilation. Therefore, it is not necessary to separately provide a hole for inserting the joining tool and a ventilation hole for ventilation. Further, the hole 82 may be used for other purposes such as wiring.

Next, an example in which the mounting member is used as something other than the shielding plate will be described. In the examples shown in FIGS. 9 and 10, the mounting member is a ground terminal. This mounting member is provided with a terminal surface on the functional piece 312. This terminal surface is a place where the ground wire is connected using a terminal screw. In the example shown in FIG. 9, in the mounting member serving as the ground terminal, the joining piece 311 is joined to the right side surface of the housing by mechanical clinching, but the mounting location is any of the bottom surface of the housing and the like. You may. The mounting member can be retrofitted at any location where mechanical clinching can be applied. In the examples shown in FIGS. 9 and 10, the mounting member serving as the ground terminal has a cross-sectional shape of a hat, and joint portions 80 are provided at both ends of the mounting member, but the configuration is not limited to this.

In the example shown in FIG. 11, the mounting member is a rail mounting bracket. This mounting member is provided with a rail mounting surface having a rail mounting hole 323 in the functional piece 322. Using this rail mounting hole, the rail to which the internal equipment is mounted can be connected to the rail mounting surface. In the example shown in FIG. 11, the mounting member serving as the rail mounting bracket is provided in a crank shape having a joint piece 321 at one end, and is cantilevered to the housing by mechanical clinching.

In the example shown in FIG. 12, the mounting member is a drawing holder. The mounting member has a functional piece 332 having a substantially U-shaped cross section so as to secure a space for storing drawings and the like. This mounting member is provided with joint pieces 331 at both ends of the functional piece 332, and has a hat cross section. Both joint pieces 331 provided on both end sides of the functional piece 332 are joined to the housing by mechanical clinching. In the example shown in FIG. 12, the mounting member is joined to the back surface of the door 11, but the mounting member functioning as a drawing holder may be joined to the front surface of the door 11 or the housing body 10.

In the example shown in FIG. 13, the mounting member is a stay device. The stay 98 for holding the door 11 in the open state is connected to this mounting member, and the stay 98 is movably connected to the joint piece 341 and the functional piece 342 having a substantially L-shaped cross section. To. This mounting member is provided in a crank shape having a joint piece 341 at one end of the functional piece 342, and is cantilevered to the housing by mechanical clinching. In the example shown in FIG. 13, the mounting member is joined to the back surface of the door 11, but in the embodiment, the mounting member to be the stay device is also coupled to the housing body 10 and is joined to the door 11. The stay 98 is connected so as to bridge both the mounting member and the mounting member joined to the housing body 10.

In the examples shown in FIGS. 14 and 15, the mounting member is a hinged door 11. In this mounting member, one side of the shaft portion of the hinge member 94 to be connected to the housing body 10 constitutes a joint piece 351 and the door 11 is a functional piece 352. The joint piece 351 provided so as to form an L shape with the functional piece 352 is joined to the housing by mechanical clinching. As in the example shown in FIGS. 14 and 15, if the housing body 10 and the hinged door 11 are to be joined by mechanical clinching, the housing body 10 and the hinged door 11 are manufactured, and the door 11 is manufactured. After confirming whether the door opens to the right or to the left, the mounting members can be joined by mechanical clinching, so it is not necessary to prepare both the housing of the right-opening door 11 and the left-opening housing in advance. Will also get better. In addition, it is possible to shorten the time from confirming the opening direction of the door 11, which is requested to be manufactured, to completing the housing. Any method of joining the hinge member 94 and the door 11 may be used.

In the example shown in FIG. 16, the mounting member is a pole mounting device. This mounting member includes joint pieces 361 joined to the housing at both ends, and functional pieces 362 attached to poles such as utility poles between the joint pieces 361. The functional piece 362 shown in FIG. 16 has a substantially M-shaped cross section, and is provided with a band insertion hole 363 through which a band used when fixing the housing to the pole can be inserted. In the example shown in FIG. 16, two mounting members are joined by mechanical clinching so as to be arranged vertically on the back surface of the housing. If the mounting member to be the pole mounting device is joined by mechanical clinching, it is easy to correspond to the mounting mode to the pole, and rainwater invades from the mounting location of the mounting member even in the case of outdoor use. There is no fear.

In the example shown in FIG. 17, the mounting member is a wall mounting bracket. This mounting member includes a joining piece 371 to be joined to the housing, and a functional piece 372 used for fixing the wall surface. The functional piece 372 shown in FIG. 17 has a through hole into which a fixing member such as a screw can be inserted. In the example shown in FIG. 17, two L-shaped mounting members are joined to the left side surface of the housing by mechanical clinching so as to be arranged in the vertical direction. If the mounting member to be the wall mounting bracket is joined by mechanical clinching, it is easy to correspond to the mounting mode on the wall surface, and rainwater invades from the mounting location of the mounting member even in the case of outdoor use. There is no fear.

As can be seen from these examples, when manufacturing a cabinet 1 comprising a metal housing and a metal mounting member that is joined to the housing to provide additional functionality, it is joined to the housing. By applying a method of mechanically clinching the joint piece to be formed and a mounting member having a functional piece that exerts an additional function to the portion erected from the joint piece, the degree of freedom in manufacturing the cabinet 1 can be increased. Since it is possible to add functions while maintaining the quality of the housing to be joined while enhancing the cabinet 1, a good cabinet 1 can be obtained.

Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be in various modes. For example, the portion of the protective surface protected by the light-shielding plate is arbitrary, and the necessary portion such as the ceiling surface or side surface of the housing or the front side of the housing may be protected. Further, the cabinet 1 is used as a box body that can store various items such as a switchboard, a server storage rack, a box for storing electronic and electrical equipment such as a cubicle, and a delivery box.
