Description

  The present invention relates to a wireless communication apparatus that can be attached to a socket together with a light emitter and is intended to be used in a place having vibration such as a train or a bus.

  In recent years, various mobile terminals capable of wireless communication such as notebook PCs and mobile phones have become widespread. Along with this, wireless communication networks have been established, and mobile terminals can access external networks by communicating directly with base stations or indirectly through repeaters. Here, it is assumed that a wireless communication device is provided as a repeater in a certain space. At this time, since the radiation range is widened and the number of obstacles is generally small, the wireless communication device is preferably provided on the ceiling of the space. However, there is a drawback that it is difficult to supply power to the wireless communication device. Thus, a wireless communication device has been developed that solves the above problems by using a fluorescent lamp socket as a power source. A conventional wireless communication apparatus will be described below with reference to FIGS. FIG. 10 is an exploded perspective view showing a wireless communication apparatus used by attaching to a conventional socket together with a fluorescent lamp. FIG. 11 is a block diagram showing a configuration of a circuit housed in a conventional wireless communication apparatus main body.

  The wireless communication apparatus main body 100 includes a substantially cylindrical casing, and a module including communication circuits 80 and 82, a control circuit 81, and a power supply circuit 83 is accommodated in the casing, and an antenna is provided outside or inside the casing. 84 and 85. In addition, a pin terminal 114 is provided at one end of the housing, and a pin mounting hole 115 is provided at the other end. Wireless communication is performed by inserting the pin terminal 114 into the pin mounting hole 113 of the socket 102a, the pin terminal 116a of the fluorescent lamp 101 into the pin mounting hole 115, and the pin terminal 116b of the fluorescent lamp 101 into the pin mounting hole 117 of the socket 102b. The apparatus main body 100 and the fluorescent lamp 101 are mechanically connected and electrically connected. As a result, the radio communication apparatus main body 100 is applied with an AC voltage from the sockets 102 a and 102 b via the fluorescent lamp 101. When the fluorescent lamp 101 is turned on and the AC voltage is stabilized, the control circuit 81 causes the power supply circuit 83 to perform a voltage conversion operation, and applies the DC voltage to the entire circuit in the wireless communication apparatus main body 100. Therefore, the wireless communication apparatus main body 100 can perform a wireless communication operation (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 8-237763

  However, in the conventional wireless communication device, the electrical and mechanical connection between the wireless communication device main body, the fluorescent lamp, and the socket is a simple method of inserting a pin terminal into the pin mounting hole. In addition, the connection between the socket that is fixed to the ceiling or the like and the wireless communication device main body, or the connection between the socket that is fixed to the fluorescent light and the connection between the wireless communication device main body and the fluorescent light that is not fixed. The strength is particularly weak. When this connection part receives external force from a direction perpendicular to the length direction of the fluorescent lamp, the connection state between the wireless communication device main body and the fluorescent lamp is not maintained, and the electrical connection between the pin terminal and the pin mounting hole is interrupted. There is a possibility. This means that both the wireless communication device main body and the fluorescent lamp are not supplied with power and cannot operate. Furthermore, there is a possibility that the mechanical connection between the wireless communication apparatus main body and the fluorescent lamp may be disconnected by receiving a large external force or repeatedly receiving the influence of the external force. That is, there is a risk that the wireless communication device main body and the fluorescent lamp will be disassembled and fall off. For this reason, there is a problem in terms of safety in attaching the wireless communication device body in a place where there is vibration such as in a train and it is assumed that a person is under the fluorescent lamp.

  Therefore, in the present invention, the connection between the wireless communication device main body and the light emitter is reinforced, so that the power supply to the wireless communication device main body and the light emitter is interrupted even if the wireless communication device main body and the light emitter are installed in a train affected by vibration or the like. It is an object of the present invention to provide a wireless communication device that is difficult to disassemble the wireless communication device main body and the light emitter.

  In order to achieve the above object, the present invention provides a wireless communication apparatus main body including a power supply unit, a control unit, and a communication unit in a hollow casing, a light emitter that emits light when power is supplied, A socket capable of supplying power by being connected electrically, and the wireless communication device main body is held and the light emitting body by electrically and mechanically connecting the connection of the wireless communication device main body and the light emitting body to the socket In the wireless communication device fed with power through the socket, disassembly preventing means for reinforcing the connection portion between the wireless communication device main body and the light emitter is provided.

  Since the present invention is configured as described above, the wireless communication device main body is not only held by the light emitter and the socket, but the connection portion between the wireless communication device main body and the light emitter is reinforced by the disassembly preventing means. Thereby, even if an external force is applied to the connection portion, the connection state is maintained by the disassembly preventing means. Therefore, even if it is used in a place where vibration occurs, such as in a train, the possibility that power supply to the wireless communication device main body and the light emitter is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device main body and the light emitter from being disassembled and falling.

  According to the first aspect of the present invention, the wireless communication device main body is not only held by the light emitter and the socket, but also the connection portion between the wireless communication device main body and the light emitter is reinforced by the disassembly preventing means. Thereby, even if an external force is applied to the connection portion, the connection state can be maintained by the disassembly preventing means. Therefore, even if it is used in a place where vibrations occur, such as in a train, the possibility of power supply to the wireless communication device body being interrupted is greatly reduced, and the wireless communication device body and the light emitter are disassembled and dropped. Can also be prevented.

  According to a second aspect of the present invention, the disassembly preventing means is constituted by a member that covers at least a connection portion between the wireless communication device main body and the light emitter.

  According to the second invention of the present invention, since at least the connection portion between the wireless communication device main body and the light emitter is covered with the disassembly preventing means, even if an external force is applied to the connection portion between the wireless communication device main body and the light emitter. Since this connection part is reinforced by the decomposition preventing means, the connection state can be maintained. Therefore, even if it is used in a place where vibration occurs, such as in a train, the possibility that power supply to the wireless communication device main body is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device main body and the light emitter from being disassembled and falling. Moreover, the fall of the illumination intensity of a light-emitting body can be suppressed, so that the part covered with a decomposition | disassembly prevention means is decreased.

  According to a third aspect of the present invention, as a means for preventing disassembly, the wireless communication apparatus main body is provided on a side connected to a light emitter, and is configured by a holding member that houses / holds at least a part of the light emitter. .

  According to the third aspect of the present invention, the holding member provided in the wireless communication apparatus main body as the decomposition preventing means stores / holds at least a part of the light emitter, so that the portion in which the light emitter is stored is the holding member. Can limit the range (especially in the direction perpendicular to the length of the light emitter). Therefore, the connection state between the wireless communication device main body and the light emitter is maintained. Therefore, even if it is used in a place where vibration occurs, such as in a train, the possibility that power supply to the wireless communication device main body is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device main body and the light emitter from being disassembled and falling. Moreover, the fall of the illumination intensity of a light-emitting body can be suppressed, so that the part hold | maintained with a holding member is decreased. Further, since the disassembly prevention means is provided in the wireless communication apparatus main body, it is possible to save the trouble of reattaching the disassembly prevention means at the connection portion between the wireless communication apparatus main body and the light emitter.

  According to a fourth aspect of the present invention, the disassembly preventing means is constituted by an interval holding member that keeps the interval between the connection portions of the wireless communication apparatus main body and the light emitter constant.

  According to the fourth aspect of the present invention, as an anti-disassembly means, an interval holding member that keeps the distance between the radio communication apparatus main body and the light emitter constant is inserted into the connection portion between the radio communication apparatus main body and the light emitter. As a result, the gaps at the connection portions of the wireless communication device main body, the light emitter, and the socket do not change. Therefore, even if an external force is applied in the direction of disassembly, the connection state is maintained by the spacing member. Therefore, even if it is used in a place where vibration occurs, such as in a train, the possibility that power supply to the wireless communication device main body is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device main body and the light emitter from being disassembled and falling. Further, since the spacing member is inserted into the connecting portion, the light emission of the light emitter is not substantially disturbed.

  According to a fifth aspect of the present invention, the disassembly preventing means is constituted by an adhesive member that adheres the connection surface between the radio communication device main body and the light emitter.

  According to the sixth aspect of the present invention, the antenna is printed on the disassembly preventing means. For this reason, the antenna can be easily installed in a narrow place by being formed thin.

(Embodiment 1)
Hereinafter, Embodiment 1 will be described with reference to FIGS. 1, 2, 3, and 4. FIG. FIG. 1 is an explanatory diagram showing an outline of communication between a radio communication apparatus and a base station in the present invention, FIG. 2 is an explanatory diagram showing an outline of communication between a radio communication apparatus in a train and a mobile terminal in the present invention, and FIG. FIG. 4 is an exploded perspective view showing an attachment state 1 of the wireless communication apparatus main body according to Embodiment 1 of the invention, and FIG. 4 is an exploded perspective view showing an attachment state 2 of the wireless communication apparatus main body according to Embodiment 1 of the present invention. First, an outline of communication between a mobile terminal and a mobile communication network in the present invention will be described with reference to FIGS.

  Both 10a and 10b are base stations, and the base stations 10a and 10b can communicate directly or indirectly with mobile terminals. Reference numeral 11 denotes a moving body. The moving body 11 is a public transportation such as a train, a bus or a taxi. Reference numeral 12 denotes a switching center. The switching center 12 switches a base station that communicates with a mobile terminal (described later) and connects to an external network. A communication cable 13 performs data transmission between the base stations 10 a and 10 b and the switching center 12. Reference numeral 20 denotes a wireless communication apparatus main body, and the wireless communication apparatus main body 20 is a repeater capable of communicating with different protocols. Reference numeral 26 denotes a mobile terminal. The mobile terminal 26 can communicate wirelessly or by wire, for example, a mobile phone, a PC, or a game machine. FIG. 2 is a diagram showing an outline inside the moving body 11.

  Here, the radio communication apparatus main body 20 performs relay between the base station 10 a and the mobile terminal 26 or between the base station 10 b and the mobile terminal 26. The wireless communication apparatus main body 20 capable of communicating with different protocols can communicate with the base stations 10a and 10b using the first protocol (described later) and can communicate with the mobile terminal 26 using the second protocol (described later). is there. This relay function enables the mobile terminal 26 to communicate with the base stations 10a and 10b having different communication protocols. Furthermore, the base stations 10a and 10b are connected to the switching center 12 via the communication cable 13, and the switching center 12 can be connected to an external network. Therefore, the mobile terminal 26 can access the external network by going through the wireless communication device main body 20, the base station 10 a (or 10 b), the communication cable 13, and the switching center 12 in this order.

  The first protocol in the first embodiment means mobile WiMAX or the like developed for a relatively wide area capable of wireless communication with the mobile terminal 26. Other than this, LTE (Long Term Evolution), HSDPA (High Speed Downlink Packet Access) known as 3.5th generation mobile communication system, HSUPA (High Speed Uplink Packet Access), and 3rd generation mobile communication system are known. CDMA2000 (Code Division Multiple Access 2000) and W-CDMA (Wideband Code Division Multiple Access) can also be used. Can be used as well. In addition to wireless, wired access is also conceivable. For example, Ethernet (registered trademark), PLC (Power Line Communications), telephone line communication (ADSL, etc.), and the like. The second protocol in the first embodiment means narrowband wireless access such as WiFi. In addition, Bluetooth, Ultra Wideband, and ZigBee can be used.

  The base stations 10a and 10b are installed according to the cell range (communication range). In an area where there is a large amount of communication, the cell range cannot be covered by one base station 10a or 10b, so a plurality of base stations 10a or 10b may be installed in the vicinity. It goes without saying that the communication range can be expanded by installing the base station 10a or 10b in many areas. However, when the mobile terminal 26 moves, the mobile terminal 26 may be outside the cell range of the base station 10a with which it was communicating, and may be within the cell range of another base station 10b. In this case, the base station communicating with the mobile terminal 26 is switched by the switching center 12. Alternatively, when the mobile terminal 26 exists within the range of the two base stations 10a and 10b, the switching center 12 selects a base station with good communication conditions. This technique is called handover, and will be described in detail with reference to FIG. The mobile terminal 26 in the mobile body 11 communicates with the base station 10a via the radio communication apparatus main body 20. At this time, as the mobile body 11 advances in the traveling direction, the mobile body 11 moves away from the base station 10a and approaches the base station 10b. The base stations 10a and 10b have the same cell radius, and there is no obstacle between the base stations 10a and 10b and the mobile unit 11. In this case, when the radio communication apparatus main body 20 enters the cell range of the base stations 10a and 10b, the mobile terminal 26 starts communication with the base station 10b while communicating with the base station 10a. At this time, since the mobile body 11 approaches the base station 10b, the wireless communication apparatus main body 20 has a better communication situation with the base station 10b. For this reason, the switching center 12 switches the base station communicating with the radio communication apparatus main body 20 from the base station 10a to the base station 10b.

  Next, a mounting location and a mounting method of the wireless communication device main body 20 in the present embodiment will be described. Reference numeral 22 denotes a fluorescent lamp as a light emitter. The fluorescent lamp 22 emits light when an AC voltage is applied thereto. Reference numerals 24a and 24b denote sockets fixed to a ceiling portion or the like, and the sockets 24a and 24b can apply an alternating voltage. The light emitter may be an incandescent lamp, LED (Light Emitting Diode) illumination, FE (Field Emission) illumination, or the like, instead of the fluorescent lamp 22, and the first embodiment will be described using a fluorescent lamp as an example.

  The wireless communication device main body 20 is attached to the sockets 24 a and 24 b together with the fluorescent lamp 22. Thereby, the radio | wireless communication apparatus main body 20 and the fluorescent lamp 22 are electrically and mechanically connected. In other words, the wireless communication device main body 20 is supplied with power from the sockets 24 a and 24 b via the fluorescent lamp 22 and is held between the socket 24 a and the fluorescent lamp 22. Although not shown, the radio communication apparatus main body 20 houses a module similar to that shown in FIG. 11 including a power supply unit, a control unit, a first communication unit, and a second communication unit in a hollow casing 20a. As a result, when an AC voltage is applied to the sockets 24a and 24b to the wireless communication device main body 20 and the fluorescent lamp 22, the fluorescent lamp 22 is turned on and then the fluorescent lamp 22 is lit to stabilize the AC voltage. Here, the control unit of the wireless communication device main body 20 causes the power supply unit to perform a voltage conversion operation, and the direct communication voltage is applied to the entire module, thereby enabling the wireless communication device main body 20 to perform a communication operation. In addition, it is necessary to provide a first antenna and a second antenna that communicate with the mobile terminal 26 or the base stations 10a and 10b in the vicinity of the radio communication apparatus main body 20. The 1st communication part which comprises the radio | wireless communication apparatus main body 20 is electrically connected with the 1st antenna, and the 2nd communication part is electrically connected with the 2nd antenna. The installation of the antenna will be described later. As a result, the wireless communication device main body 20 communicates with the base station 10a or 10b using the first protocol via the first communication unit and the first antenna. Similarly, the wireless communication device main body 20 communicates with the mobile terminal 26 by the second protocol via the second communication unit and the second antenna. The sockets 24a and 24b are located on the ceiling in the moving body 11, but the wireless communication device main body 20 may be attached to a socket located on the wall or floor. However, it is desirable to attach the radio communication device main body 20 to the sockets 24a and 24b in the ceiling from the viewpoint of widening the radiation range. Note that the number of communication units stored in the housing 20a may be three or more. As a result, the wireless communication device main body 20 becomes a repeater capable of communicating with more protocols. The communication unit is a part that performs data transmission and reception through an antenna. The radio communication device main body 20 may divide its role into a plurality of roles. For example, by storing modules in a plurality of housings and electrically connecting the modules in these housings, the role of one wireless communication device main body 20 in communication can be taken.

  As described above, the wireless communication device main body 20 is supplied with power and is held in the sockets 24 a and 24 b together with the fluorescent lamp 22. However, the moving body 11 vibrates in the moving body 11 by moving. As a result, when used in the moving body 11 or the like, the wireless communication device main body 20 and the fluorescent lamp 22 swing vertically and horizontally due to the influence of vibration. For this reason, each electrical connection of the radio communication apparatus main body 20, the fluorescent lamp 22, and the sockets 24a and 24b may be interrupted. That is, power is not supplied to the wireless communication device main body 20, and the role as a relay device cannot be taken. Furthermore, the mechanical connection between the wireless communication device main body 20 and the fluorescent lamp 22 is disconnected, and the wireless communication device main body 20 and the fluorescent lamp 22 may be disassembled and fall. In addition, compared to the connection portion between the socket 24a fixed to the ceiling or the like and the wireless communication device main body 20, or the connection portion between the socket 24b fixed to the ceiling or the like and the fluorescent lamp 22, neither wireless communication is fixed. The connection strength of the connection portion between the apparatus main body 20 and the fluorescent lamp 22 is particularly weak. Therefore, in the first embodiment, a disassembly preventing means for reinforcing the connection between the wireless communication device main body 20 and the fluorescent lamp 22 is provided.

  Hereinafter, a method for reinforcing the connection and connection of the wireless communication apparatus main body 20 according to the first embodiment will be described with reference to FIGS. 3 and 4. First, attachment of the wireless communication device main body 20 will be described in detail. Reference numeral 20b denotes an end surface, and the end surface 20b is a surface of one end of the wireless communication device main body 20 on the side connected to the fluorescent lamp 22. 22b is an end surface, and the end surface 22b is a surface of one end of the fluorescent lamp 22 on the side connected to the wireless communication device main body 20. 41 is a pin mounting hole, and the pin mounting hole 41 is provided in the socket 24a. 42 is a pin terminal, 43 is a pin mounting hole, the pin terminal 42 is provided at one end of the radio communication apparatus main body 20, and the pin mounting hole 43 is provided at the other end (end face 20b) of the radio communication apparatus main body 20. 44 and 45 are both pin terminals. The pin terminal 44 is provided at one end (end surface 22 b) of the fluorescent lamp 22, and the pin terminal 45 is provided at the other end of the fluorescent lamp 22. 46 is a pin mounting hole, and the pin mounting hole 46 is provided in the socket 24b. Each connection is established by inserting a pin terminal into the pin mounting hole. Therefore, by inserting the pin terminal 42 into the pin mounting hole 41, the pin terminal 44 into the pin mounting hole 43, and the pin terminal 45 into the pin mounting hole 46, the wireless communication device main body 20, the fluorescent lamp 22, and the sockets 24a and 24b Are electrically and mechanically connected.

  Next, a method for reinforcing the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22 will be described. 30a is a decomposition | disassembly prevention means, and is comprised with a protection sheet. The protective sheet 30a has translucency and adhesiveness, and is formed of a resin or the like. The protective sheet 30a is attached so as to cover the connected wireless communication device main body 20 and the fluorescent lamp 22, thereby reinforcing the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22. The first antenna 27 and the second antenna 28 are formed on the protective sheet 30a by printing. 30b is a protective sheet as a means for preventing disassembly, and this protective sheet 30b has the same function as the protective sheet 30a except that the antenna is not printed. The protective sheet 30b is attached so as to cover only the connection portion between the wireless communication device body 20 and the fluorescent lamp 22, thereby reinforcing the connection portion between the wireless communication device body 20 and the fluorescent lamp 22. Actually, it is possible to print the antenna on the protective sheet 30b. However, when printing, since the width of the protective sheet 30b is narrow, the two antennas are positioned in the vicinity, and the antennas may interfere with each other and adversely affect communication. Therefore, the first antenna 27 and the second antenna 28 are printed independently on a separate sheet from the protective sheet 30 b and provided in the wireless communication apparatus main body 20. Conversely, as shown in FIG. 4, the first antenna 27 and the second antenna 28 are provided in the wireless communication apparatus main body 20, and are entirely covered with the protective sheet 30 a, and the first antenna 27 and the second antenna 28 of the protective sheet 30 a A configuration in which notches are provided in the opposing portions is also possible. Further, from the viewpoint of preventing a decrease in the illuminance of the fluorescent lamp 22, the first antenna 27 and the second antenna 28 are provided in the radio communication device main body 20 as shown in FIGS. It is preferable to be provided on the side. In this case, the ground surfaces of the first antenna 27 and the second antenna 28 are directed upward, and the microslip surface is directed downward. Thereby, the radiation directions of the first antenna 27 and the second antenna 28 can be directed toward the mobile terminal 26. Therefore, a high quality communication environment can be provided to the mobile terminal 26 and the illuminance of the fluorescent lamp 22 is not disturbed. Although not shown, an opening is provided in the housing 20a, and an antenna outside the housing 20a is electrically connected to a communication unit inside the housing 20a by passing a power supply line through the opening. In the first embodiment, the first antenna 27 and the second antenna 28 are provided outside the housing 20a, but may be provided inside. However, it is preferable to provide outside for improvement of antenna characteristics.

  With the above configuration, even when an external force is applied to the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22, the connection portion is reinforced by the protective sheets 30a and 30b, and thus is easily maintained. In other words, the linear direction connecting the pin terminal 44 and the pin mounting hole 43 and the length direction of the fluorescent lamp 22 are kept parallel. Therefore, even if it is used in a place where vibration occurs, such as in a train, the possibility that power supply to the wireless communication device main body 20 is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device body 20 and the fluorescent lamp 22 from being disassembled and falling. Further, since the space between the wireless communication device main body 20 and the fluorescent lamp 22 and the ceiling portion is generally narrow, the range in which the antenna can be installed is limited. However, by using the protective sheet 30a in the first embodiment, the wireless communication device main body 20 and the fluorescent lamp 22 can be integrated and connected to the sockets 24a and 24b in a state where the antenna is also connected. For this reason, the connection of the radio | wireless communication apparatus main body 20 can be performed very efficiently. Further, the first antenna 27 and the second antenna 28 printed on the protective sheet 30a may be printed at positions separated from each other. For example, the first antenna 27 is printed on the protective sheet 30a on the socket 24a side, and the second antenna 28 is printed on the protective sheet 30a on the socket 24b side. The second antenna 28 on the socket 24b side and the module in the housing 20a can be easily electrically connected by printing a feeding line on the protective sheet 30a. Thereby, the first antenna 27 and the second antenna 28 are less likely to interfere with each other, and the antenna characteristics can be improved. In addition, even when the first antenna 27 and the second antenna 28 are not printed on the protective sheet 30b as shown in FIG. 4, the antenna at a position away from the radio communication apparatus main body 20 and the module in the housing 20a are electrically connected. It is only necessary to provide a power supply line to be connected. Furthermore, since the protective sheet 30b covers only the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22, the light emitting portion of the fluorescent lamp 22 and the protective sheet 30b do not substantially face each other. For this reason, the fall of the illumination intensity of the fluorescent lamp 22 is suppressed significantly. Therefore, in the case of the protection sheet 30b, it is also possible to be comprised with the material which does not have translucency.

  In the first embodiment, the case where the entire wireless communication device main body 20 and the fluorescent lamp 22 are covered or only the connection portion is covered has been described. However, the connection portion is included in the portion covered by the protective sheets 30a and 30b. It only has to be done. Therefore, the widths of the protective sheets 30a and 30b may be long or short, and the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22 may be reinforced with a plurality of protective sheets 30a and 30b. For example, the protective sheets 30a and 30b may be wound spirally as long as the connection portion is reinforced. However, although the protective sheets 30a and 30b have translucency, it is possible to suppress a decrease in illuminance by winding the protective sheet 30a and 30b only around the connection portion like the protective sheet 30b. In this case, the protective sheet 30b may not cover the light emitting part of the fluorescent lamp 22, and the part covered by the wireless communication device main body 20 may be a part or the whole. The first antenna 27 and the second antenna 28 are more easily formed on the protective sheet 30b by printing as the width covering the radio communication device main body 20 is larger. On the other hand, the first antenna 27 and the second antenna 28 can be easily printed by covering the entirety of the wireless communication device body 20 and the fluorescent lamp 22 like the protective sheet 30a.

  Further, like the protective sheets 30a and 30b, they may not be a sheet but may be a cylindrical object or a clip body. In the case of a cylindrical object, it is preferable to have translucency with a material such as a resin that has little influence on the antenna characteristics. The clip body refers to a clip body that can reinforce the connecting portion by sandwiching the connecting portion. The shape is, for example, a cylindrical shape that can cover the connecting portion between the fluorescent lamp 22 and the wireless communication device main body 20, and a notch is provided in a part of the cylindrical shape. In the case of the clip body, when the fluorescent lamp 22 breaks down, the connection between the wireless communication device main body 20 and the fluorescent lamp 22 can be easily removed. Furthermore, it is possible to coat the wireless communication device main body 20 and the fluorescent lamp 22 and completely integrate them instead of the cylindrical object or the clip body. In this case, the connection state between the wireless communication device body 20 and the fluorescent lamp 22 is maintained, but the fluorescent lamp 22 cannot be replaced. In the first embodiment, the fluorescent lamp 22 provided with the pin terminals 44 and 45 on both sides is taken as an example. However, the fluorescent lamp 22 provided with the pin terminal 44 or 45 only at one end may be used.

(Embodiment 2)
In the second embodiment, the description of the attachment of the wireless communication device main body 20 is the same as that in the first embodiment, and is therefore omitted. Hereinafter, a method for reinforcing the connection of the wireless communication apparatus main body 20 according to the second embodiment will be described with reference to FIGS. 5 is an exploded perspective view showing an attachment state 1 of the wireless communication apparatus main body according to the second embodiment of the present invention, and FIG. 6 is an exploded perspective view showing an attachment state 2 of the wireless communication apparatus main body according to the second embodiment of the present invention. is there. Moreover, the same code | symbol is attached | subjected to the member provided with the same structure and function as Embodiment 1, and detailed description is abbreviate | omitted.

  First, a configuration common to FIGS. 5 and 6 will be described. Reference numeral 32 denotes a decomposition preventing means, which is constituted by a holding member. This holding member 32 is a decomposition preventing means in the second embodiment having a substantially cylindrical shape. The holding member 32 is provided on the end surface 20b which is a surface of one end of the housing 20a, and is configured to be able to store a part of the fluorescent lamp 22. The wireless communication device main body 20 according to the second embodiment includes a holding member 32 on the end surface 20b side of the housing 20a, in addition to having the same configuration as that of the first embodiment.

  Next, a specific configuration shown in FIG. 6 will be described. In addition to the configuration of FIG. 5, a movable member 32a and a spring 32b are provided in the holding member 32, and a pin mounting hole 32c is provided in the movable member 32a. The spring 32b is a power supply line between the pin mounting hole 43 and the pin mounting hole 32c, and is also a connecting member between the end surface 20b and the movable member 32a. The movable member 32a is not fixed to the holding member 32 and moves back and forth in the X direction by the expansion and contraction of the spring 32b. Note that the spring 32b merely connects the end face 20b and the movable member 32a, and there is no problem even if a new power supply line for electrically connecting the pin mounting hole 43 and the pin mounting hole 32c is provided. In FIG. 6, the number of springs 32b is two. However, the number of springs 32b may be one, three, or any number. Further, the spring 32b may be another member as long as the member has an elastic characteristic that can move the movable member 32a back and forth in the X direction.

  In the above configuration, a part of the fluorescent lamp 22 is inserted into the holding member 32, and the pin terminal 44 is inserted into the pin mounting hole 32c, so that the wireless communication device body 20 and the fluorescent lamp 22 are electrically and mechanically. Connected. Therefore, the fluorescent lamp 22 is not only inserted into the pin mounting hole but also held by the holding member 32. That is, the fluorescent lamp 22 is held by the holding member 32 even if it receives an external force from a direction perpendicular to the length direction. Thereby, the possibility that the connection state between the wireless communication device main body 20 and the fluorescent lamp 22 can be maintained is greatly enhanced. In addition, since the holding member 32 is already provided in the wireless communication device main body 20, it is possible to save the trouble of reattaching the disassembly prevention means at the connection portion between the wireless communication device main body 20 and the fluorescent lamp 22.

  Further, with the unique configuration in FIG. 6, when the fluorescent lamp 22 is pushed in the X direction, the spring 32b in the holding member 32 contracts and the movable member 32a moves in the X direction. Thus, the length of the wireless communication device main body 20 and the fluorescent lamp 22 added can be adjusted by the elastic characteristics of the spring 32b. Therefore, the fluorescent lamps 22 having different lengths can be attached to the sockets 24a and 24b, and the wireless communication device main body 20 and the fluorescent lamp 22 can be easily attached. Further, when the wireless communication device body 20 and the fluorescent lamp 22 are attached to the sockets 24a and 24b with the spring 32b contracted, the spring 32b tends to extend in the direction opposite to X. That is, the movable member 32a presses the fluorescent lamp 22 against the socket 24b. Therefore, the fluorescent lamp 22 is not only held by the holding member 32 but also held between the movable member 32a and the socket 24b by the specific structure shown in FIG. Thereby, possibility that the connection state of the radio | wireless communication apparatus main body 20 and the fluorescent lamp 22 can be maintained is raised further. Furthermore, it is possible to prevent the wireless communication device body 20 and the fluorescent lamp 22 from being disassembled and falling. Accordingly, even if the wireless communication device main body 20 is attached in a place having vibrations such as in a train, power supply to the wireless communication device main body 20 is not interrupted, and a stable communication operation is possible.

  As long as the holding member 32 has a cylindrical shape, the inner diameter and the outer diameter of the holding member 32 may be circular or polygonal. When the inner diameter of the holding member 32 is circular, the inner diameter of the holding member 32 is preferably slightly larger than the outer shape of the fluorescent lamp 22 to be housed. Moreover, when the internal diameter of the holding member 32 is a polygon, the structure where the plane inside the holding member 32 and the external shape of the fluorescent lamp 22 contact | connect is also possible. In this case, the fluorescent lamp 22 is held by the holding member 32 more. Furthermore, in Embodiment 2, since the holding member 32 which is a decomposition | disassembly prevention means and the fluorescent lamp 22 are not combined, the fluorescent lamp 22 can be removed freely. For this reason, even if the fluorescent lamp 22 becomes unable to emit light, it can be easily replaced.

  Needless to say, the holding member 32 may be configured by a plurality of arms or the like in a direction parallel to the length direction of the fluorescent lamp 22 as long as it can hold a part of the fluorescent lamp 22 even if it is not cylindrical. . In order to prevent the illuminance of the fluorescent lamp 22 from decreasing, the holding member 32 is preferably a light-transmitting material, a material such as a resin that has little influence on antenna characteristics, or a material having elastic characteristics. If the holding member 32 has translucency, or if the function as illumination of the fluorescent lamp 22 can be ensured by providing a notch in a part of the holding member 32, not all of the fluorescent lamp 22 but the whole is stored. A possible configuration is also possible.

  Furthermore, the holding member 32 may be integrated with the radio communication apparatus main body 20 as in the second embodiment, but may be a separate body. For example, the case of a separate body is a holding member 32 provided between the wireless communication apparatus main body 20 and the fluorescent lamp 22 and having a cylindrical object on both sides. In this case, the holding member 32 can hold a part of the wireless communication device main body 20 and the fluorescent lamp 22 and relays the electrical connection between the wireless communication device main body 20 and the fluorescent lamp 22.

(Embodiment 3)
In the third embodiment, the description of the attachment of the wireless communication device main body 20 is the same as that in the first embodiment, and is omitted. Hereinafter, a method for reinforcing the connection of the wireless communication apparatus main body 20 in the third embodiment will be described with reference to FIGS. 7, 8, and 9. FIG. 7 is a schematic configuration diagram showing an attachment state 1 of the wireless communication device main body according to Embodiment 3 of the present invention, and FIG. 8 is a schematic configuration diagram showing an attachment state 2 of the wireless communication device main body according to Embodiment 3 of the present invention. FIG. 9 is an explanatory view showing the insertion position of the wedge according to the third embodiment of the present invention. Here, members having the same configurations and functions as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, the configuration of FIG. 7 will be described. Reference numeral 33 denotes a decomposition preventing means in the configuration of FIG. The wedge 33 has a triangular prism shape, and is inserted into a gap in a connection portion between the wireless communication device main body 20 and the fluorescent lamp 22 attached to the sockets 24a and 24b. Here, the insertion positions of the two wedges 33 will be described with reference to FIG. FIG. 9 is a view when a cross section when the attachment state of the wireless communication apparatus main body 20 in FIG. 7 is divided by a dotted line is viewed from the direction opposite to X. The Y direction is a direction in which passengers of the moving body 11 exist. In other words, the fluorescent lamp 22 aims to illuminate in the Y direction. Therefore, in Embodiment 3, the wedge 33 is provided on the semicircular side of the fluorescent lamp 22 in the direction opposite to Y so as not to hinder the role of the fluorescent lamp 22 as an illumination device.

  With the above configuration, the wedge 33 keeps the gaps generated at the connecting portions of the wireless communication device main body 20, the fluorescent lamp 22, and the sockets 24a and 24b constant. That is, the range in which the wireless communication device main body 20 and the fluorescent lamp 22 can move is greatly limited, and electrical interruption and the disassembly of the wireless communication device main body 20 and the fluorescent lamp 22 can be prevented. Therefore, even if it is used in a place having vibrations such as a train, the possibility that power supply to the wireless communication device main body 20 is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device body 20 and the fluorescent lamp 22 from being disassembled and falling. From the viewpoint of easy insertion of the wedge 33, it is preferable that one corner of the bottom surface of the triangular prism is an acute angle. However, the wedge 33 may be a member that can be provided in the gap between the connection portions of the wireless communication device main body 20 and the fluorescent lamp 22 and can maintain a constant gap between the connection portions, even if it is not a triangular prism. The number of wedges 33 to be inserted may be one or two or more. However, by inserting the two wedges 33 symmetrically as in the third embodiment, the gaps between the connecting portions are more evenly maintained.

  Next, the configuration of FIG. 8 will be described. Reference numeral 20e denotes a protrusion, and the protrusion 20e has a columnar shape, which is a disassembly prevention means in the configuration of FIG. The protrusion 20e is connected to the spring 20d. Although not shown, the end face 20b is provided with two holes separately from the pin mounting holes 43, and the protrusions 20e are inserted into the two holes, respectively. The wireless communication device main body 20 has an inner surface 20c in the housing 20a, and a spring 20d connects the inner surface 20c and the protrusion 20e. The position of the inner surface 20c is fixed in the housing 20a, and the protrusion 20e moves back and forth in the X direction by the expansion and contraction of the spring 20d. Thus, when the pin terminal 44 is inserted into the pin mounting hole 43, the end face 22b of the fluorescent lamp 22 pushes the protrusion 20e in the X direction, and the spring 20d contracts. In this state, when the wireless communication device main body 20 and the fluorescent lamp 22 are attached to the sockets 24a and 24b, the spring 20d tends to extend in the direction opposite to X.

  With the above configuration, the protrusion 20e keeps the gaps generated at the connecting portions of the wireless communication device main body 20, the fluorescent lamp 22, and the sockets 24a and 24b constant. That is, the range in which the wireless communication device main body 20 and the fluorescent lamp 22 can move is greatly limited, and the possibility of electrical interruption and disassembly of the wireless communication device main body 20 and the fluorescent lamp 22 is greatly reduced. . Therefore, when used in a place with vibrations such as a train, the possibility that the power supply to the wireless communication device main body 20 is interrupted is greatly reduced. Furthermore, it is possible to prevent the wireless communication device body 20 and the fluorescent lamp 22 from being disassembled and falling. The number of protrusions 20e and the number of springs 20d connected to the protrusions 20e do not have to be two, and the larger the number, the stronger the reinforcement. Further, the shape of the protrusion 20e may be a polygonal column. The spring 20d may be another member as long as the member has an elastic characteristic capable of moving the protrusion 20e back and forth in the X direction.

  Moreover, the end surface 20b and the end surface 22b can also be couple | bonded with an adhesive member, a double-sided tape, etc. As a result, the connection between the wireless communication device main body 20 and the fluorescent lamp 22 becomes stronger, but there is a possibility that the fluorescent lamp 22 cannot be replaced.

  The wireless communication device of the present invention is applied as a device capable of communication in places where there are vibrations such as in trains, buses, airplanes, taxis, etc., because the connection part between the wireless communication device main body and the fluorescent lamp is reinforced by the disassembly prevention means. Is possible.
