  An electrical apparatus according to an embodiment of the present invention will be described with reference to FIGS. Here, the radio 1 is an example of the electric device, and is used by being brought into a work place such as a construction site.

  As shown in FIG. 1, the radio 1 includes a radio main body 2 and a frame guard 3. The radio main body 2 has a long casing 10 that extends in the left-right direction when installed in a work place, and a cross section along a plane orthogonal to the left-right direction of the casing 10 has a substantially triangular shape.

  An operation unit 11, a display unit 12, a protective cover 13, and a pair of speaker units 14 that output sound are provided on the front side of the housing 10. The pair of speaker units 14 are positioned on the left and right end sides of the housing 10, and the operation unit 11, the display unit 12, and the protective lid 13 are positioned between the pair of speaker units 14. The operation unit 11 is for exerting a radio function, and is provided with a dial and a push switch (not shown). The display unit 12 includes, for example, a liquid crystal panel that displays information to be used for operation, and is positioned above the operation unit 11. The protective lid 13 is located between the left speaker portion 14 and the operation portion 11 and includes a transparent portion 13A. The protective lid 13 is provided so that it can be opened and closed. In a state where the protective lid 13 is closed, the operation unit 11, the display unit 12, and the surfaces of the protective lid 13 are substantially flush.

  As shown in FIG. 4A, since the casing 10 has a substantially triangular shape in cross section, the front surface thereof is inclined with respect to the horizontal plane (makes an acute angle with respect to the bottom surface). Since the front surface on which the operation unit 11 and the display unit 12 are arranged is inclined, it is easy for a user who works standing up to visually recognize the operation unit 11 and the display unit 12. In addition, since the operation unit 11 and the display unit 12 are arranged on a single surface on the front surface, the user can check and operate the display on only one surface when operating the radio 1. Convenience is improved.

Here, the front surface of the housing 10 is compared with the conventional housing 101 having a rectangular shape in a sectional view (FIG. 4B) having the same height (h) as the height (h) of the housing 10. the length of (L ₁₎ is to become longer than the vertical length of the front (L ₂₎ of the housing 101, it is possible to increase the front to place the operating unit 11 and display unit 12 or the like than conventional it can. By enlarging the front surface, the operation unit 11 and the display unit 12 can be enlarged, and even a user wearing gloves can easily operate and the operability is improved.

  An open / close switch 15 for opening and closing the protective lid 13 is provided on the upper left side of the housing 10 on the left side immediately above the protective lid 13. By pressing the open / close switch 15, the protective lid 13 can be opened. When the lid 13 is closed, a state in which the protective lid 13 is closed is held by being caught by a claw (not shown).

  A pair of woofer portions 16 are provided on both side surfaces of the housing 10 in the left-right direction. By providing the woofer unit 16, it is possible to effectively output a low frequency range.

  On the bottom surface side (not shown) of the housing 10, a storage portion (not shown) that stores an outlet cord for obtaining power from a commercial power source is formed. In addition, a power supply battery (not shown) is accommodated in the housing 10. Since the radio body 2 includes both a power battery and an outlet cord, whether the power source battery or the outlet cord is used depends on whether the work place where the radio 1 is used is a place where commercial power can be used or not. Can be appropriately selected. A voice input / output mechanism (not shown) is further provided inside the housing 10, and radio broadcasts can be output from the pair of speaker units 14 and the woofer unit 16.

  As shown in FIGS. 5 and 7, a storage unit 13 a that stores a portable sound reproduction device 200 that is an external device is provided behind the protective lid 13. The storage unit 13 a provides a substantially rectangular space that is recessed inward of the housing 10 from the surfaces of the operation unit 11 and the display unit 12. The storage portion 13a is provided with a pair of holding portions 17 and a storage cushioning material 18, and is formed with a connection hole 13b.

  As shown in FIG. 7, the connection hole 13b is formed in such a manner that it is recessed downward in the approximate center of the lower surface of the storage portion 13a so that the USB connector 43 of the connector unit 4 described later can be inserted and connected. The connector unit 4 mounts the portable sound reproduction device 200 with the USB connector 43 inserted into the connection hole 13b, and electrically connects the portable sound reproduction device 200 and the sound input / output mechanism. The storage cushioning material 18 is provided at a substantially central portion in the vertical direction of the storage unit 13a, abuts against the back surface of the stored portable sound reproduction device 200, and absorbs and reduces the impact. The pair of holding portions 17 are provided in the vicinity of the lower side of the storage cushioning material 18 so as to be slidable in the left-right direction, and hold and hold the portable sound reproduction device 200 from the left direction and the right direction. For this reason, when the portable sound reproducing device 200 is fixed to the housing 10 and carried with the portable sound reproducing device 200 placed on the storage unit 13a, the portable sound reproducing device 200 may be detached from the storage unit 13a. It can suppress falling, and it can suppress that the portable sound reproduction apparatus 200 vibrates with respect to the storage part 13a, and these surfaces are damaged.

  In a state where the protective lid 13 is open, the portable sound reproducing device 200 can be stored and placed in the storage unit 13a, or can be taken out from the storage unit 13a. In the state where the protective lid 13 is closed, the portable sound reproducing device 200 is protected from dust, water, or an impact from the outside. In addition, since the protective lid 13 includes the transparent portion 13A, the portable sound reproducing device 200 can be visually recognized from the outside in a state where the protective lid 13 is closed, so that the user can use the stored portable sound reproducing device 200. It is possible to confirm the type, the information display unit of the portable sound reproduction device 200, and the like, and it is possible to confirm whether or not the portable sound reproduction device 200 is placed on the storage unit 13a.

  When the portable sound reproduction device 200 and the sound input / output mechanism are electrically connected via the connector unit 4, sound data of the portable sound reproduction device 200 is input to the sound input / output mechanism, and the sound data is included in the sound data. Based on this, music or the like is output from the pair of speakers 14 and the woofer unit 16. Alternatively, the portable sound reproduction device 200 can be charged by electrically connecting the portable sound reproduction device 200 and the voice input / output mechanism via the connector unit 4. In this case, the audio data of the portable sound reproduction device 200 can be transmitted to the audio input / output mechanism via a wireless LAN or the like.

  As shown in FIGS. 8A, 9A, and 9B, the connector unit 4 includes a case 41 that is a seat portion, a terminal connection portion 42 that is a first connection portion, and a second connection portion. A USB connector 43 and a cable 44. As shown in FIG. 9A, the case 41 is a portion that forms the main body of the connector unit 4, and the upper portion is bent rearward at the substantially vertical center. The width in the left-right direction of the case 41 is designed to be approximately the same as the width in the left-right direction of the portable sound reproduction device 200, so that the portable sound reproduction device 200 can be stably placed. The terminal connection part 42 extends from the approximate center of the upper surface of the case 41 in a direction orthogonal to the upper surface, and can be electrically connected to the portable sound reproducing device 200. The USB connector 43 extends from the approximate center of the lower surface of the case 41 (the surface opposite to the upper surface with respect to the case 41) in a direction orthogonal to the lower surface, and is inserted into the connection hole 13b to connect the audio input / output mechanism and the electric connector. Can be connected. The cable 44 is disposed inside the case 41 and electrically connects the terminal connection portion 42 and the USB connector 43.

  Since the case 41 is bent substantially backward at the center in the vertical direction, the extending direction of the terminal connecting portion 42 and the extending direction of the USB connector 43 intersect each other. For this reason, the direction in which the connection between the terminal connection unit 42 and the portable sound reproduction device 200 is released differs from the direction in which the connection between the USB connector 43 and the audio input / output mechanism is released. When the connection with the sound reproduction device 200 is released, it is possible to suppress or prevent the connection between the USB connector 43 and the audio input / output mechanism from being unintentionally released.

  Specifically, as shown in FIG. 9A, the force in the b direction required for releasing the connection between the connector unit 4 and the audio input / output mechanism is Fb, and the portable sound reproducing device 200 and the connector unit It is assumed that the force in the a direction applied to the connector unit 4 when the connection with the connector 4 is released is Fa, and that Fa and Fb are substantially equal in magnitude. When the portable sound reproducing device 200 is detached from the connector unit 4 with the force of Fa, the force in the b direction acting on the connector unit 4 becomes the b direction component of Fa, that is, Facosθ, and the portable sound reproducing device 200 and the sound input / output mechanism It becomes smaller than the force Fb in the b direction necessary for releasing the connection. By providing the angle θ in the a direction and the b direction, it is possible to suppress the disconnection between the connector unit 4 and the audio input / output mechanism when the connection between the playback device 200 and the connector unit 4 is cancelled. .

  FIG. 8A shows the connector unit 4 including a terminal connection portion 42 that can be connected to an external connection terminal of the iPhone (registered trademark) 5. FIG. 8B shows a connector unit 4A including a terminal connection portion 42A that can be connected to an external connection terminal of iPhone (registered trademark). FIG. 8C shows a connector unit 4B including a terminal connection portion 42B that can be connected to an external connection terminal of ANDROID (registered trademark). 8A, 8 </ b> B, and 8 </ b> C are different in the shape of the terminal connection portions 42, 42 </ b> A, and 42 </ b> B, but the shape of each USB connector 43 is the same.

  As described above, the connector units 4, 4A, and 4B including the terminal connection portions 42, 42A, and 42B corresponding to one of a plurality of types of portable sound reproducing devices 200 having different shapes and standards of the external connection terminals are prepared. Thus, the user can select a connector unit as appropriate according to the type of the portable sound reproduction device 200 and store it in the storage unit 13a to electrically connect the portable sound reproduction device 200 and the audio input / output mechanism. . Even if a new standard or the like of the external connection terminal of the portable sound reproduction device 200 appears in the future, a new connector unit having a terminal connection unit 42 that meets the standard is newly produced. It is possible to comply with the standard.

  As shown in FIGS. 1 to 3, the frame guard 3 includes a guard portion 31, a first connector 32, and a second connector 33. The guard portion 31 is composed of three aluminum hollow bar-shaped guards. The first guard 31A is disposed above the radio body 2, and the second guard 31B is disposed forward and downward of the radio body 2. A third guard 31 </ b> C is disposed at the lower rear of the radio body 2. The first connector 32 connects one end (right end) in the left-right direction of each guard to each other, and the second connector 33 connects the other end (left end) in the left-right direction of each guard. As shown in FIG. 2B, the first connector 32 is substantially isosceles with the first guard 31A as a vertex when viewed from the left-right direction and the line connecting the second guard 31B and the third guard 31C as the base. It has a triangular shape.

  Since it has a substantially isosceles triangle shape when viewed from the left-right direction as described above, the number of guards can be reduced compared to a conventional frame guard that forms a quadrilateral shape when viewed from the left-right axis extension line, The number of guard parts 31, the first connector 32, and the second connector 33 for manufacturing the frame guard 3 can be reduced, and the manufacturing cost of the frame guard 3 can be reduced.

  As shown in FIGS. 1 and 2B, the first connector 32 is formed in a substantially isosceles triangular shape from three connecting members 32A and three connecting rods 32B. The connecting member 32A is made of polypropylene (PP), and the connecting member 32A has a fitting hole for fitting with the connecting rod 32B, and one of the first guard 31A, the second guard 31B, and the third guard 31C. A fitting hole for fitting with the left and right end portions is formed. The connecting rod 32B is made of aluminum and has a hollow rod shape.

  One end of one connecting rod 32B is fitted and fixed in a fitting hole formed in one connecting member 32A, and the other end of the connecting rod 32B is fitted in a fitting hole formed in another connecting member 32A. By fixing with, one connecting member 32A and the other connecting member 32A are connected.

  The guard part 31 and the first connector 32 are connected by fitting and fixing the right and left ends of the three guards of the guard part 31 to the connecting member 32A. The second connector 33 has the same configuration, and the guard portion 31 and the second connector 33 are connected by fitting the left end portions of the three guards of the guard portion 31 into the connecting member 33A.

  According to the above configuration, the first connector 32 is formed in a substantially isosceles triangle shape by the three connecting members 32A and the three connecting rods 32B, but is particularly orthogonal to the left-right direction of the housing 10. In the case of a radio main body whose cross section along the plane is an equilateral triangle, the three connecting members may be equilateral triangles. In that case, all the three connecting members 32A used for manufacturing the first connector 32 can have the same shape, and the types of members necessary for manufacturing the frame guard 3 can be reduced. Costs can be reduced by reducing the number of processes.

  Further, in the case of a radio main body having a regular triangular or isosceles triangular cross section along a plane orthogonal to the left-right direction of the housing 10, the first guard 31 </ b> A is positioned substantially immediately above the center of gravity of the radio main body 2. Therefore, it is optimal as a handle when carrying. Further, the first guard 31A can be carried by providing a soft material or the like that reduces the burden on the handle at the approximate center in the left-right direction, or by providing a handle portion that has a shape at the approximate center in the left-right direction to fit the handle. Becomes easier.

  As shown in FIGS. 1 to 3, the connecting members 32A and 33A are orthogonal to the plane including the first guard 31A and the second guard 31B, and orthogonal to the plane including the first guard 31A and the third guard 31C. And the viewing direction and the left-right direction as it goes to the left-right direction end, even when viewed from any viewing direction of the direction perpendicular to the plane including the second guard 31B and the third guard 31C. Both of them include arc portions 32a and 33a whose dimensions in the orthogonal direction are gradually reduced. By having such arc portions 32a and 33a, when the arc portion receives a mechanical impact, the impact is dispersed, and the impact acting on the electric device body can be efficiently reduced. In addition, the entire radio 1 is easy to roll, and the impact can be reduced by rolling.

  As shown in FIG. 1, the connecting members 32 </ b> A and 33 </ b> A are directly screwed to the radio main body 2 by a plurality of screws 50 as fixing means, and the frame guard 3 is fixed to the radio main body 2. Acoustically, in order to reproduce the sound, it is best that only the vibration source (cone) built in the speaker vibrates to reproduce the sound, and that the support that supports the vibration source does not vibrate. It is said that. In order to suppress the vibration of the support, there is a method of increasing the mass of the support. According to said structure, since the radio main body 2 is being fixed with respect to the frame guard 3, it cannot move, and the mass of the support body which supports the vibration source is the sum total of the frame guard 3 and the radio main body 2. Is the mass. For this reason, compared with the case of only the radio main body 2, the mass of the said support body becomes large, and the reproducibility of sound becomes high. Moreover, since the screw is used as the fixing means, the frame guard 3 can be fixed and connected to the radio main body 2 easily.

  As shown in FIG. 4 (c), the radio main body 2 has a substantially triangular area surrounded by the frame guard 3 (the first guard 31A is located in any cross section along the plane orthogonal to the left-right direction). It is arranged on the inner side of a triangle with the line segment connecting the second guard 31B and the third guard 31C as the base. Further, as shown in FIGS. 1 to 3, any surface of the radio body 2 is located inside the frame guard 3. For this reason, even when a long timber or the like is about to fall down, the timber or the like collides with the frame guard 3 first, so that the radio main body 2 can be further protected.

  An impact cushioning material 300 made of an elastomer for absorbing impact from the outside is provided on the opposite surface (the hatched portion in FIG. 1) of each of the coupling material 32A and the coupling material 33A. It is provided by injection molding and is a so-called two-layer molding. Therefore, when the radio 1 falls on the ground or when the construction material is about to fall down, the shock absorbing material 300 can absorb and reduce the shock, thereby protecting the radio body 2 and the frame guard 3 itself. Furthermore, damage and breakage of the connecting members 32A and 33A themselves can be suppressed, and the aesthetic feeling of the radio 1 can be maintained. Further, when the radio 1 is placed on the floor or the like, the shock absorbers 300 provided on the surfaces of the connecting member 32A and the connecting member 33A facing the floor or the like come into contact with the floor, so that the floor or the like is damaged. Can be prevented.

  The shock-absorbing material 300 is provided on each of the connecting members 32A and 33A so as to protrude to the opposite side of the radio body 2 from the first guard, the second guard, and the third guard when viewed from the left-right direction. For this reason, when an electric device collides with a wall or a floor during carrying, the shock absorbing material 300 collides with the wall or the floor before the first guard, the second guard, and the third guard, and acts on the radio body 2. It is possible to protect the radio main body 2 by absorbing and relaxing the impact, and to prevent the guards themselves from being damaged or damaged.

  In the above-described embodiment, the electric device main body is a radio, but various device main bodies such as a CD reproducing device and a portable television can be applied. In addition, a housing portion that houses the plurality of connector units 4, 4 </ b> A, and 4 </ b> B described above may be provided on the back surface of the housing 10.
