  The communication device 1 includes a housing 3 that is an outline of the communication device 1. The housing | casing 3 is comprised with the metal material excellent in heat conductivity like aluminum alloy, for example. The housing 3 is formed in a square box shape by combining the first case 4 and the second case 5.

  The first case 4 includes a square front plate 6 and four side plates 7 rising from the outer peripheral edge of the front plate 6. The front plate 6 has an outer surface 6 a exposed to the outside of the first case 4. The outer surface 6 a of the front plate 6 faces the installation surface 2 when the communication device 1 is installed on the installation surface 2. The front edge portions of the side plates 7 cooperate with each other to define a square first opening 8. The first opening 8 faces the front plate 6.

  The first flange portion 9 is formed integrally with the tip edge portion of the side plate 7. The first flange portion 9 is bent at a right angle from the tip edge portion of the side plate 7 to the outside of the first case 4 and continuously surrounds the first opening 8 in the circumferential direction.

  The second case 5 includes a square back plate 11 and four side plates 12 rising from the outer peripheral edge of the back plate 11. The back plate 11 has an outer surface 11 a exposed to the outside of the second case 5. The outer surface 11 a is positioned on the opposite side of the installation surface 2 when the communication device 1 is installed on the installation surface 2. The front edge of the side plate 12 cooperates with each other to define a square second opening 13. The second opening 13 faces the back plate 11.

  The second flange portion 14 is formed integrally with the tip edge portion of the side plate 12. The second flange portion 14 is bent at a right angle from the front end edge of the side plate 12 to the outside of the second case 5, and continuously surrounds the second opening 13 in the circumferential direction.

  The first flange portion 9 of the first case 4 is abutted against the second flange portion 14 of the second case 5. The first flange portion 9 and the second flange portion 14 are connected to each other via a plurality of screws 15. The screw 15 passes through the second flange portion 14 and is screwed into the first flange portion 9.

  By this screwing, the first case 4 and the second case 5 are integrally coupled so that the first opening 8 and the second opening 13 are matched. The first case 4 and the second case 5 cooperate with each other to form a device housing chamber 16 inside the housing 3.

  As shown in FIGS. 1 to 3, radiation fins 17 are integrally formed on the outer surface 6 a of the front plate 6 of the first case 4 and the outer surface 11 a of the back plate 11 of the second case 5. The radiating fins 17 are erected from the outer surfaces 6 a and 11 a and extend in a straight line in the height direction of the installation surface 2. Further, the heat radiating fins 17 are arranged in parallel with a space between each other.

  As shown in FIG. 2, the power supply unit 20 and the communication circuit module 21 are accommodated in the device accommodating chamber 16 of the housing 3. The power supply unit 20 is fixed to the inner surface of the front plate 6 of the first case 4 and is thermally connected to the front plate 6.

  The circuit module 21 includes a circuit board 22 and a plurality of circuit components 23 such as a CPU. The circuit board 22 is screwed to the tips of a plurality of boss portions 24 protruding from the inner surface of the back plate 11 of the second case 5 and is arranged in parallel with the back plate 11. Therefore, the circuit board 22 has a first surface 22a that faces the inner surface of the back plate 11, and a second surface 22b that is positioned on the back side of the first surface 22a.

  The circuit component 23 is mounted on the first surface 22 a of the circuit board 22. The circuit component 23 is thermally connected to the inner surface of the back plate 11. According to the present embodiment, the power supply unit 20 and the circuit module 21 are both examples of a heating element that is thermally connected to the housing 3 because both generate heat during operation.

  Therefore, the heat generated by the power supply unit 20 is directly transmitted to the first case 4 and is released to the outside of the housing 3 mainly from the outer surface 6a of the front plate 6 and the heat radiation fins 17 of the first case 4. . Similarly, the heat generated by the circuit module 21 is directly transmitted to the second case 5 and is released to the outside of the housing 3 mainly from the outer surface 11a of the back plate 11 of the second case 5 and the radiation fins 17. The

  Furthermore, in the present embodiment, a shield case 25 that covers other circuit elements is attached on the second surface 22 b of the circuit board 22.

  As best shown in FIGS. 2 and 3, a pair of handles 28 are attached to the front plate 6 of the first case 4. The handle 28 is an element that is gripped by a finger of a hand when the communication device 1 is transported or installed on the installation surface 2, for example, and is configured by, for example, bending a belt-shaped metal plate integrally.

  The handles 28 are separated from each other in the width direction of the housing 3 so as to sandwich the radiating fins 17 of the front plate 6 therebetween. In other words, the handle 28 is adjacent to the outer surface 6a of the front plate 6 with a gap in the width direction of the housing 3.

  The handle 28 includes a pair of arm portions 29 and a grip portion 30. Each of the arm portions 29 includes a first portion 31a along the outer surface 6a of the front plate 6 and a second portion 31b bent at a right angle from one end of the first portion 31a.

  The first portion 31 a is fixed to the end portion of the outer surface 6 a of the front plate 6 via a screw 32. The second portion 31 b protrudes from the outer surface 6 a so as to stand up with respect to the outer surface 6 a of the front plate 6. As shown in FIGS. 1 and 4, the protruding height H <b> 1 of the arm portion 29 is set to be larger than the protruding height H <b> 2 of the radiating fin 17 on the front plate 6.

  The grip part 30 straddles between the protruding ends of the second part 31 b of the arm part 29. The grip portion 30 extends in a straight line parallel to the front plate 6 at a position away from the front plate 6 of the first case 4 along the installation surface 2.

  A pair of through holes 34 a and 34 b are formed in the grip portion 30. The through holes 34 a and 34 b are for passing a plurality of fixing bolts 35, which are an example of a fixture, and are separated from each other in the longitudinal direction of the grip portion 30.

  The communication device 1 having such a configuration is held on the installation surface 2 in a vertically installed posture along the standing installation surface 2. Specifically, the grip portions 30 of the pair of handles 28 protruding from the housing 3 are brought into contact with predetermined positions on the installation surface 2. In this state, the fixing bolt 35 is inserted into the through holes 34 a and 34 b of the grip part 30, and the fixing bolt 35 is screwed into the screw hole formed in the installation surface 2.

  By this screwing, the housing 3 of the communication device 1 is fixed to the installation surface 2, and the carrying handle 28 can be used as a bracket for installing the communication device 1 on the installation surface 2. At this time, since the protruding height H1 of the arm portion 29 of the handle 28 is larger than the protruding height H2 of the radiating fin 17, the communication device 1 is placed on the installation surface 2 as shown in FIGS. In the held state, the tips of the radiation fins 17 protruding from the first case 4 are separated from the installation surface 2. Therefore, a space 36 necessary for heat radiation is secured between the heat radiation fins 17 of the first case 4 and the installation surface 2.

  At the same time, a sufficient space for inserting fingers of the hand between the grip portion 30 of the handle 28 and the heat dissipating fins 17 adjacent to the handle 28 can be secured. Therefore, when the grip part 30 of the handle 28 is gripped by the hand, the radiating fins 17 do not become an obstacle.

  According to this embodiment, the handle 28 of the communication device 1 protrudes from the front plate 6 of the first case 4 of the housing 3 toward the installation surface 2 on which the communication device 1 is to be installed. For this reason, when the communication device 1 is installed on the installation surface 2 using the handle 28, the handle 28 is located between the front plate 6 of the housing 3 and the installation surface 2.

  Therefore, the handle 28 does not protrude around the side plates 7 and 12 of the first and second cases 4 and 5 and does not protrude from the back plate 11 of the second case 5. As a result, the handle 28 does not adversely affect the outer dimensions of the communication device 1 and the communication device 1 can be prevented from being enlarged.

  In addition, the space required for installing the communication device 1 can be minimized. Therefore, the degree of freedom in installing the communication device 1 on the installation surface 2 is increased, and the installation operation of the communication device 1 can be easily performed.

  In the present embodiment, through holes 34 a and 34 b through which the fixing bolt 35 is passed are formed in the grip portion 30 of the handle 28. For this reason, the function as a bracket for installing the housing 3 of the communication device 1 on the installation surface 2 can be added to the handle 28 itself. Therefore, a dedicated mounting bracket for installing the communication device 1 on the installation surface 2 can be omitted, and the number of parts can be reduced.

  Furthermore, in a state where the communication device 1 is installed on the installation surface 2, a space 36 is secured between the installation surface 2 and the tips of the radiation fins 17. Thereby, the heat radiation fin 17 can be efficiently cooled by the air flowing through the space 36, and the heat dissipation of the communication device 1 can be enhanced.

  In the present embodiment, the number of handles is not limited to a pair, and for example, handles may be provided at four locations on the outer peripheral portion of the front plate of the first case.

  An electronic device such as a communication device is not limited to being installed in a vertical posture on a standing installation surface. For example, the electronic device may be installed in a horizontal posture on a horizontal floor surface.

  Furthermore, in this embodiment, the through hole through which the fixing screw is passed is provided in the grip portion of the handle. However, for example, the grip portion may be held on the installation surface using a dedicated mounting bracket.

  In addition, the electronic device is not specified as a communication device, and can be implemented in the same manner even if it is another device such as an information device.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
