Description

  The present invention relates to an underwater wireless LAN communication system for an electronic device and an underwater wireless LAN communication cable. More particularly, the present invention relates to an underwater wireless LAN communication system and an underwater wireless LAN communication cable that can communicate with each other by connecting an underwater wireless LAN device and another wireless LAN device with an underwater wireless LAN communication cable.

  In recent years, many wireless LAN devices having a wireless LAN communication function have been provided. The wireless LAN communication unit is small and easy to incorporate, and is a relatively compact portable type such as a smartphone, tablet terminal, PDA (Personal Digital assistant), notebook computer, digital camera, portable game machine, etc. Wireless LAN devices are rapidly spreading.

In a wireless LAN device that has been authenticated by a communication standard such as Wi-Fi (registered trademark), interoperability between devices of different manufacturers is guaranteed. Therefore, in the wireless LAN device, for example, the communication terminals are connected to the Internet via an access point, or communication terminals are directly connected wirelessly without going through the access point. For example, by connecting via wireless LAN communication, an image captured by a digital camera is displayed on a smartphone, and shooting of the digital camera is started by operating the smartphone.

  By the way, the frequency of radio waves for wireless LAN communication is almost the same as the frequency of radio waves used in microwave ovens. For this reason, when the wireless LAN device is used underwater, the transmitted radio waves are converted into heat by the surrounding water and absorbed. For example, when a waterproof digital camera and a smartphone are connected by wireless LAN communication, the communication is disconnected when the waterproof digital camera is submerged in water.

  In general, in water, radio waves are greatly attenuated as the distance increases. For this reason, as an underwater communication system, a signal is converted into a very long wave, a very long wave, or an ultrasonic wave or light. An underwater communication system with such signal conversion is generally large. For this reason, a wireless LAN device underwater is connected to another wireless LAN device using a communication cable, and even a relatively compact portable wireless LAN device with a simple structure can be handled. Underwater wireless communication systems have been desired.

  A conventional underwater wireless communication system using these communication cables is disclosed in Patent Document 1. This underwater wireless communication system is configured to communicate a wireless device in water with another wireless device using a communication cable.

  That is, wireless communication is performed between a wireless device in water and a waterproof communication conversion device joined to the wireless device with a suction cup or the like. The radio signal received by the reception unit of the communication conversion device is once converted into digital data by the communication conversion unit in the communication conversion device. The digital data is sent to another communication conversion device via a communication cable. The sent digital data is again converted into a radio signal by a communication conversion unit in another communication conversion device and transmitted. The wireless signal is received by another wireless device joined to the transmitter. Communication is possible even when the two wireless devices are separated in water.

  Moreover, there exists what was disclosed by patent document 2 as an underwater radio | wireless communications system using these communication cables. This underwater wireless communication system is configured such that communication is performed without converting any wireless signal by connecting a wireless device in water and another wireless device with a transmission medium such as a cable.

  That is, a transmission medium that connects two wireless devices is made of a non-conductive material such as synthetic resin or rubber. The radio signal is greatly attenuated in water, but is transmitted in a transmission medium made of synthetic resin or rubber. A wireless signal can be transmitted as it is, a signal conversion is not necessary, and an underwater wireless communication system with a simple configuration can be realized.

Is provided. Further, waterproof microphones 2d and 2d (not shown) are provided on the front sides of the left and right sides. As the material of the case 2a, a strong and rigid resin such as a polycarbonate resin or a nylon resin containing glass fiber is used.

The waterproof imaging terminal 2 includes an imaging terminal antenna unit 2e for wireless LAN communication (not shown) inside the case 2a. The imaging terminal antenna unit 2e is provided on the inner surface side of the front side of the recording button 2c on the front side of the upper surface of the case 2a shown in FIG. That is, when the user U holds the waterproof imaging terminal 2 and operates the recording button 2c with a finger, the imaging terminal antenna unit 2e is disposed at a position where the imaging terminal antenna unit 2e is not covered with a hand. . This is to reduce the possibility that the imaging terminal antenna unit 2e is covered with a finger of a hand that is held and the wireless LAN signal is absorbed by the hand.

As shown in FIG. 3, the waterproof imaging terminal 2 includes an imaging element 2f, a video signal processing circuit 2g, an audio signal processing circuit 2h, an operation unit 2i, a control unit 2j, a memory 2k, and a wireless communication unit 2n. doing.

The portable terminal antenna portion 3e is disposed on the inner surface side of the case 3a at a position slightly from the center of the imaging lens 3b provided at the upper left part of the front surface of the case 3a shown in FIG. That is, when the user U is holding the mobile terminal 3 and operating it with a finger or the like, the mobile terminal antenna part 3e is disposed at a position where the mobile terminal antenna part 3e is not covered with a hand. This is to reduce the possibility that the portable terminal antenna 3e is covered by a finger of the hand that is held and the wireless LAN signal is absorbed by the hand.

  The front portion of the case 3a of the portable terminal 3 is made of a metal such as a thin plate-like aluminum except for a part thereof. The portion of the front portion of the case 3a that covers the vicinity of the mobile terminal antenna portion 3e is not a metal, but is made of a non-metallic material such as glass or resin. This is because the metal case 3a blocks the wireless LAN signal. Since the portion covering the vicinity of the mobile terminal antenna portion 3e is made of a non-metallic material, the wireless LAN signal passes through without being blocked by the front portion of the case 3a.

As shown in FIG. 3, the mobile terminal 3 includes a speaker 3f, a video signal processing circuit 3g, an audio signal processing circuit 3h, a control unit 3j, a memory 3k, and a wireless communication unit 3n.

The wireless communication unit 3n converts the wireless LAN signal into a digital signal, or converts the digital signal into a wireless LAN signal. As a result of the operation of the operation unit 3d, digital signals such as received video and audio are recorded or reproduced by the memory 3k connected to the control unit 3j. The received digital signals such as video and audio are displayed on the display unit 3c via the video signal processing circuit 3g and output as audio from the speaker 3f via the audio signal processing circuit 3h.

  As shown in FIG. 3, when the operation unit 3d is operated with respect to instructions for imaging, imaging stop, reproduction, and the like of the waterproof imaging terminal 2, the operation content of the operation unit 2i is input to the control unit 2j. The control unit 2j performs wireless LAN communication with the imaging terminal antenna unit 2e via the wireless communication unit 2n and transmits the instruction content.

Next, the communication cable 4 will be described.

  As shown in FIG. 2, an antenna body 4 d which is a loop antenna having a substantially Ω (omega) shape capable of transmitting and receiving a wireless LAN signal is provided inside the first antenna portion 4 b and the second antenna portion 4 c. 4d are arranged. Moreover, the cable part 4a is comprised with the flexible coaxial cable (electric wire) which has the core wire 4e and the braided wire 4f distribute | arranged to the outer periphery. The core wire 4e and the braided wire 4f of the coaxial cable are connected to the base portions of the two ends of the antenna body 4d so as to be energized by soldering or the like.

Here, the antenna body 4d may be a metal plate or a film antenna in which an antenna is formed of a metal thin film or the like on a film. In addition, a wire or the like may be formed into a ring shape or the like, or an electric wire at the end of the cable portion 4a may be used as it is and may be used after forming.
Moreover, although the coaxial cable was used for the cable part 4a, as long as it can transmit the wireless LAN signal received with the antenna main body 4d as it is, you may use another kind of electric wire.

  The first antenna part 4b and the second antenna part 4c are formed by general insert molding. That is, first, the antenna body 4d to which the coaxial cable is connected is loaded into the mold. Next, resin is poured into a mold and filled, and the antenna body 4d is wrapped with a molten resin, solidified, and integrated. In the present embodiment, a strong and highly rigid resin such as a polycarbonate resin or an ABS (acrylonitrile butadiene styrene) resin is used as the resin to be injected into the mold.

  As shown in FIG. 2, cylindrical cable protection bush portions 4g and 4g are provided at both ends of the cable portion 4a to protect the base portions at both ends of the cable portion 4a. The cable protection bush portion 4g may be joined with another part or may be insert-molded together with the antenna body 4d.

  As shown in FIG. 2, an adhesive portion as a joint portion (joint portion) is provided on the surfaces of the back surfaces of the first antenna portion 4 b and the second antenna portion 4 c where the waterproof imaging terminal 2 and the mobile terminal 3 are joined. 4h and 4h (adhesion part) are provided. In the present embodiment, the adhesive portions 4h and 4h are constituted by a releasable adhesive sheet. Since the adhesive sheet is a re-peelable sheet, the antenna unit 4b can be joined to the wireless LAN device only when necessary, and can be peeled when unnecessary.

  Here, the pressure-sensitive adhesive sheet used is a pressure-sensitive adhesive surface that can be re-peeled on one side and a strongly-adhesive surface on the other side. It is configured with. By using a sheet-like material such as an adhesive sheet for the adhesive parts 4h and 4h, the first antenna part 4b and the second antenna part 4c can be made thin as a whole.

  Examples of the detachable adhesive sheet having such adhesive parts 4h and 4h include a TG sheet (trade name) and a urea sheet (trade name). In the TG sheet (trade name), a special elastomer is used for the releasable adhesive surface. Therefore, dust, dust, and the like attached to the sheet can be removed by washing with water, can be used repeatedly, and the attached wireless LAN device does not shift and is not damaged. Also, in the case of a urea sheet (trade name), the adhesive strength of the adhesive surface which can be removed again is revived by wiping with water. As the base material of the pressure-sensitive adhesive sheet, a resin film such as PET (polyethylene terephthalate) resin is used, but a sheet of foamed foam material may be used.

How the underwater wireless LAN communication system 1 works in underwater shooting will be described with reference to FIGS.
As described above, the waterproof imaging terminal 2 and the portable terminal 3 are connected by wireless LAN communication. In normal use, the waterproof imaging terminal 2 is operated cordlessly by the portable terminal 3, and the angle of view of the waterproof imaging terminal 2 before shooting, the captured video during shooting, or the video reproduced after shooting can be confirmed. ing. However, when the waterproof imaging terminal 2 is submerged in water, the wireless LAN communication connection is disconnected. This is because the wireless LAN signal is absorbed by the surrounding water.

  As shown in FIGS. 1 to 4, the first antenna portion 4 b of the communication cable 4 is located at a position on the upper surface of the case 2 a of the waterproof imaging terminal 2 that is substantially opposite to the imaging terminal antenna portion 2 e or in the vicinity thereof. It is joined by the adhesive part 4h. Further, the second antenna portion 4c of the communication cable 4 is joined to the outer surface of the case 3a of the portable terminal 3 at or near the position facing the portable terminal antenna portion 3e by an adhesive portion 4h.

  As described above, the reason why the antenna unit of the wireless LAN device and the antenna unit of the communication cable are arranged substantially opposite to each other across the case or in the vicinity thereof is to obtain stronger sensitivity. . In the case of the mobile terminal 3, the front surface of the case 3a is made of a metal that blocks the wireless LAN signal. However, since the portion of the case 3a that covers the vicinity of the mobile terminal antenna portion 3e is made of a non-metallic material, stronger sensitivity is obtained. Is obtained.

  As shown in FIG. 3, the waterproof imaging terminal 2 is located under the water surface S and underwater. The first antenna portion 4b is joined to the outer surface of the case 2a of the waterproof imaging terminal 2 in a watertight manner by the adhesive portion 4h. The wireless LAN signal transmitted from the imaging terminal antenna unit 2e is received by the first antenna unit 4b joined in a watertight manner without being affected by water. Since the cable portion 4a can transmit the wireless LAN signal as it is, the wireless LAN signal received by the first antenna portion 4b is directly transmitted to the second antenna portion 4c. The wireless LAN signal transmitted from the second antenna unit 4c is received by the mobile terminal antenna unit 3e.

  In the above description, the case where a wireless LAN signal is sent from the waterproof imaging terminal 2 to the portable terminal 3 via the communication cable 4 has been described, but the reverse is also true. That is, a wireless LAN signal is sent from the portable terminal 3 to the waterproof imaging terminal 2 via the communication cable 4. In this way, the waterproof imaging terminal 2 and the portable terminal 3 can communicate with each other via the communication cable 4 even when the waterproof imaging terminal 2 is in water.

  As shown in FIG. 4, the user U captures the underwater fish F while holding the waterproof imaging terminal 2 in the left hand while holding the portable terminal 3 in the right hand and watching the screen of the display unit 3c. can do. Here, an instruction such as imaging and imaging stop of the waterproof imaging terminal 2 may be performed by operating the operation unit 2 i such as the recording button 2 c of the waterproof imaging terminal 2 or by operating the operation unit 3 d of the portable terminal 3. May be.

  Here, the case where the case 3a of the portable terminal 3 has a watertight structure and is waterproof will be described. The second antenna portion 4c is watertightly joined to the outer surface of the case 3a by an adhesive portion 4h. If it does so, the wireless LAN signal transmitted / received by the portable terminal antenna part 3e can mutually communicate between the 2nd antenna parts 4c joined watertight, without receiving the influence of water. That is, the waterproof imaging terminal 2 and the waterproof portable terminal 3 can communicate with each other via the communication cable 4 even when the entire underwater wireless LAN communication system 1 is underwater.

  With the above configuration, wireless LAN signal communication between the waterproof imaging terminal 2 and the portable terminal 3 via the communication cable 4 is possible even when the waterproof imaging terminal 2 or both are underwater. It was. Since the communication cable 4 is merely joined to the cases 2a and 3a, it is not necessary to make holes or the like in the cases 2a and 3a, and the waterproof performance can be maintained as it is.

  In addition, since the communication cable 4 directly transmits the wireless LAN signal between the one and the other antenna without converting the signal, the number of components is small, and it can be manufactured at a low cost with a simple configuration. became. As described above, the underwater wireless LAN communication system 1 and the communication cable 4 are simple and compact, but can be easily used, and can be used for relatively compact wireless LAN devices. It was. Here, since it can respond also to a comparatively compact wireless LAN device, it can of course be used conveniently even in a larger wireless LAN device.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, as in the first embodiment, the underwater wireless LAN communication system 1 includes a waterproof imaging terminal 2, a portable terminal 3, and a communication cable 4, and has the same functions. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.

  FIG. 5 is a perspective view showing a state in which the waterproof imaging terminal 2 and the portable terminal 3 are connected by the communication cable 4, the waterproof imaging terminal 2 is located under the water surface S and is underwater, and images the fish F and the like. FIG. FIG. 6 is a perspective view showing details of the case 2a of the mobile terminal 3 to which the second antenna portion 4c is joined and the details of the second antenna portion 4c.

As shown in FIG. 5, the waterproof imaging terminal 2 is a waterproof digital camera as in the first embodiment, but the shape of the case 2a is different. The case 2a of the waterproof imaging terminal 2 of the present embodiment has a substantially cylindrical shape, not a substantially rectangular parallelepiped shape as in the first embodiment. Moreover, although the portable terminal 3 is a substantially rectangular and flat smartphone as in the first embodiment, the antenna joint portion 3p, which is a portion of the case 2a to which the second antenna portion 4c is joined, has a dent. Is formed.

  As shown in FIG. 5, along the substantially cylindrical case 2a of the waterproof imaging terminal 2, the first antenna portion 4b of the communication cable 4 is joined. That is, the first antenna portion 4b has flexibility and a flexible configuration. The second antenna unit 4c has the same shape and configuration as the first antenna unit 4b. The first antenna portion 4b and the second antenna portion 4c are formed by using a film antenna as the antenna bodies 4d and 4d and insert-molding flexible elastomer resin.

  In the first antenna portion 4b having high rigidity shown in the first embodiment, when the case 2a is substantially cylindrical, only a part of the adhesive portion 4h is joined, and the joining strength is reduced. Become. In this embodiment, it has flexibility and has a flexible structure, and can be joined along the substantially cylindrical case 2a. In some cases, the outer surface of the case of a smartphone or the like is not a flat surface but a slightly curved surface. In this case, the first antenna portion 4b is joined with a flexible one rather than a rigid one. Cheap.

  As shown in FIG. 5 and FIG. 6, the first antenna portion 4 b and the second antenna portion 4 c include a finger hook portion 4 i that is a protrusion on the tongue piece at one corner. The finger-hanging portion 4i is a tongue-like protrusion for pinching with the fingertip when the first antenna portion 4b or the second antenna portion 4c is peeled off. Since the first antenna portion 4b and the second antenna portion 4c are joined by a releasable adhesive portion 4h, it is not easy to remove them. The user U can easily peel off the first antenna part 4b or the second antenna part 4c without damaging the tip of the fingernail or the nail polish applied to the fingernail by the finger hooking part 4i. Can do.

  About the finger-hanging part 4i, although it was set as the tongue-shaped protrusion shape in this embodiment, it is not limited to this. For example, you may comprise in ring shape like what is called a pull top (trademark) used for a drink container. If it is ring-shaped, it becomes possible to put a finger and pull it, and the first antenna part 4b or the second antenna part 4c can be peeled off more easily.

  In the present embodiment, the first antenna portion 4b, the second antenna portion 4c, and the finger hanging portion 4i are integrally formed. However, the finger hanging portion 4i may be formed by combining different parts. Even when the first antenna portion 4b and the second antenna portion 4c are highly rigid, the finger-hanging portion 4i can be easily formed by combining different parts.

  As shown in FIG. 5 and FIG. 6 (A), there is a recess in the antenna joint portion 3p of the portable terminal 3, and a mark mark 3q indicating the antenna joint portion 3p is displayed in the recess. . For the mark 3q, for example, a symbol indicating an antenna is attached by printing or digging. The size of the recess in the display antenna joint 3p is formed slightly larger than the size of the mobile terminal antenna 3e. Here, the position to which the mark mark 3q is attached is a position facing the mobile terminal antenna unit 3e or its vicinity. This is to obtain stronger sensitivity during wireless LAN communication.

  By attaching a mark 3q to a predetermined position of the case 3a, the user U can join the first antenna part 4b or the second antenna part 4c to the optimal position of the mobile terminal 3 without hesitation. It becomes possible. Further, since the antenna joint portion 3p is recessed by one step, the protruding amount of the second antenna portion 4c becomes small and is difficult to peel off.

  As shown in FIG. 6A, in the present embodiment, the antenna joint 3p is recessed one step, the mark 3q is attached, and the second antenna 4c is joined in the recess. It is not limited to this configuration. For example, as shown in FIG. 6B, the antenna joint 3p may be indicated and a mark mark 3q may be attached to the surface of the case 3a simply by printing or the like. In this case, the mark mark 3q or the like can be attached by printing or the like without changing the shape of the case 3a.

  Further, as shown in FIG. 6C, a configuration may be adopted in which a mark label 5 indicating the antenna joint 3p and having a mark mark 5a is attached. In this case, the user U can attach the mark label 5 to the mobile terminal 3 later and attach the mark 5a. Once the landmark label 5 is pasted once at the optimum position of the wireless LAN communication device, the user U can attach the communication cable 4 without reexamining the optimum position. . Of course, the waterproof imaging terminal 2 may be configured such that the mark mark 3q or the like is attached or the mark label 5 is attached.

  With the above configuration, wireless LAN signal communication between the waterproof imaging terminal 2 and the portable terminal 3 via the communication cable 4 is possible even when the waterproof imaging terminal 2 or both are underwater. It was. Since the communication cable 4 is merely joined to the cases 2a and 3a, it is not necessary to make holes or the like in the cases 2a and 3a, and the waterproof performance can be maintained as it is.

  In addition, since the communication cable 4 directly transmits the wireless LAN signal between the one and the other antenna without converting the signal, the number of components is small, and it can be manufactured at a low cost with a simple configuration. became. As described above, the underwater wireless LAN communication system 1 and the communication cable 4 are simple and compact, but can be easily used, and can be used for relatively compact wireless LAN devices. It was.

In the present embodiment, a film antenna is used as the antenna body 4d, but the present invention is not limited to this. For example, a flexible wire or the like may be used as the antenna body 4d. A flexible wire is formed into a substantially ring shape or the like, and the cable portion 4a is connected to the two end portions by soldering or the like. Further, for example, the antenna body 4d may be formed so as to form the end of the cable portion 4a. By configuring in this way, it is possible to obtain a communication cable 4 that is inexpensive and suitable for low-volume production.
Moreover, although elastomer resin was used as a molding material, it is not limited to this. For example, rubber or the like may be used.

FIG. 10A is a cross-sectional view cut from the position of the slit opening 8e and viewed from the front. The antenna portion 4b is housed in the antenna housing portion 8f, which is an inner surface portion of the front case 7b, and is pressed by the elastic force of the imaging terminal protective cover 8.

  As shown in FIG. 10A, the first antenna portion 4b is joined to the upper surface of the case 2a by the adhesive portion 4h, accommodated in the antenna accommodating portion 8f, and compressed by the elastic force of the imaging terminal protective cover 8. Has been. Here, the first antenna portion 4b is positioned inside the imaging terminal protective cover 8, and the cable portion 4a needs to be pulled out of the imaging terminal protective cover 8. Since the slit opening 8e is provided under the antenna housing portion 8f, the second antenna portion 4c and the cable portion 4a can be pulled out from the slit opening 8e.

  In addition, the waterproof microphones 2d and 2d (not shown) are disposed at the positions of the slit openings 8e on the left and right sides of the waterproof imaging terminal 2, and can collect sound.

Next, the protective cover 9 for portable terminals will be described.
As shown in FIG. 9, the protective cover 9 for portable terminals is comprised so that the portable terminal 3 of a substantially rectangular and flat shape may be covered. The portable terminal protective cover 9 is made of a flexible and flexible elastomer, and the inner dimension of the portable terminal protective cover 9 is slightly smaller than the outer dimension of the portable terminal 3. In the mounted state, the entire portable terminal protective cover 9 is stretched by the portable terminal 3 inside, so that the portable terminal protective cover 9 presses the outer surface of the case 3a of the portable terminal 3 with a predetermined elastic force. Press contact. The mobile terminal protective cover 9 serves to protect the mobile terminal 3 from being scratched or impacted when it is bumped or dropped.

In addition, when a cable part is pulled, you may comprise so that an antenna part may be hold | maintained by an antenna part accommodating part so that an antenna part may not move to a horizontal direction. It can be made difficult to move or peel off against the force pulling the cable portion.

(Modified embodiment of the fourth embodiment)
With reference to FIG. 9 and FIG. 10, a modified embodiment of the fourth embodiment in which a part of the configuration of the fourth embodiment is slightly modified will be described.
As shown in FIGS. 10A and 10B, in the fourth embodiment, the adhesive portion 4h is provided at a position in the lower surface direction of the first antenna portion 4b so as to be joined to the waterproof imaging terminal 2. It is configured. A modification of the fourth embodiment is a modification of this configuration, in which the vertical direction of the first antenna portion 4b is reversed.

That is, the adhesive portion 4h of the first antenna portion 4b is directed to the upper surface direction so as to be joined to the antenna housing portion 8f on the inner surface of the imaging terminal protective cover 8 (holding device). In the case of this configuration, the first antenna portion 4b is attached to the waterproof imaging terminal 2 by the predetermined elastic force of the imaging terminal protective cover 8 instead of being joined to the case 2a by the adhesive portion 4h. It is in close contact with the case 2a and joined in a watertight manner so that wireless LAN communication is possible.
In the present embodiment, a cover sheet (to be described later) may be placed on the lower surface side portion of the first antenna portion 4b. By covering the cover sheet, the surface becomes smoother and the adhesion between the waterproof imaging terminal 2 and the case 2a can be improved.

  Here, the outer surface of the first antenna portion 4 b joined to the imaging terminal protective cover 8 and the case 2 a of the waterproof imaging terminal 2 are pressed into contact with each other by the elastic force of the imaging terminal protective cover 8. In this configuration, when watertightness between the outer surface of the first antenna portion 4b and the case 2a, particularly when subjected to an impact or the like in water, water may enter between the two and a thin water layer may be generated. There is a problem.

As shown in FIG. 9, for example, when a strong force is applied to the communication cable 4, a force that peels the first antenna portion 4 b from the waterproof imaging terminal 2 works and may be separated for a moment. If they are separated, water enters between the outer surface of the first antenna portion 4b and the case 2a.
Here, since the elastic force of the protective cover 8 for the imaging terminal is working, the first antenna portion 4b and the case 2a immediately move so as to be in close contact with each other, so that the water between the two is eliminated and the water tightness is again obtained. Return to the state of joining.

  However, there is a possibility that the water between the first antenna portion 4b and the case 2a cannot be completely removed, and a thin layer of water may remain in some portions. Here, it should be noted that radio waves are not shielded and shielded by water, but are absorbed by water and greatly attenuated by increasing distance in water. Radio waves are absorbed by the thin water layer between the outer surface of the first antenna portion 4b and the case 2a, but the distance is small, and there is little influence on the wireless LAN communication. it can.

Thus, when the 1st antenna part 4b is joined to the inner surface of the protective cover 8 for imaging terminals, the 1st antenna part 4b can be attached or detached with the waterproof imaging terminal 2 with the protective cover 8 for imaging terminals. Further, when the underwater shooting is finished and the waterproof imaging terminal 2 is to be used normally, it is only necessary to remove the protection cover 8 for the imaging terminal, so that the trouble of peeling the first antenna portion 4b from the waterproof imaging terminal 2 can be saved. .
The portable terminal protective cover 9 may also have the same configuration.

  In addition, in 4th Embodiment and deformation | transformation embodiment, although the protective cover 9 for portable terminals is comprised from the elastomer which is flexible resin, it is not limited to this. For example, a resin having high rigidity and elasticity such as polycarbonate resin or ABS resin may be used.

Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.

  FIG. 11 is a perspective view showing a state in which the underwater wireless LAN communication system 1 is integrally held by the pole-type holder 10 and the waterproof imaging terminal 2 is imaging under the water surface S and in the water. The waterproof imaging terminal 2 is held by an imaging terminal mount 11 (holding device), and the portable terminal 3 is held by a portable terminal mount 12 (holding device) and connected by a communication cable 4. 12 (A) and 12 (B) are cross-sectional views of the cross-section in the direction of the arrow CC in FIG. 11 as viewed from the left side. FIG. 12A shows the situation when the waterproof imaging terminal 2 is held before the waterproof imaging terminal 2 is held by the imaging terminal mount 11.

The pole type holder 10 will be described.
As shown in FIG. 11, the pole holder 10 includes an upper pole portion 10a and a lower pole portion 10b. The upper part of the lower pole part 10b is retractably accommodated on the inner surface of the upper pole part 10a. A handle portion 10c is provided at the upper end of the upper pole portion 10a, and a stopper 10d is provided at the lower end. The stopper 10d is provided with a substantially L-shaped upper arm portion 10e protruding in the lateral direction. The lower pole portion 10b is provided with a substantially L-shaped lower arm portion 10f protruding in the lateral direction. An upper holding portion 10g and a lower holding portion 10h are respectively provided at the distal ends of the upper arm portion 10e and the lower arm portion 10f, and hold the imaging terminal mount 11 and the portable terminal mount 12 in a rotatable manner.

The imaging terminal mount 11 will be described.
Here, the first antenna portion 4b of the present embodiment is not directly joined to the case 2a of the waterproof imaging terminal 2 or the waterproof case 6 for the imaging terminal, but is incorporated in the mount 11 for the imaging terminal. ing. Then, by attaching the waterproof imaging terminal 2 to the imaging terminal mount 11, the first antenna portion 4 b is configured so that the waterproof imaging terminal 2 is joined in a watertight manner.

  As shown in FIGS. 11 and 12A and 12B, the imaging terminal mount 11 includes a square cylindrical mount portion 11a and an attachment portion 11b integrally formed on the lower surface of the mount portion 11a. Yes. An attachment hole 11c is formed in the attachment part 11b, and is configured to be detachable from the lower holding part 10h of the lower arm part 10f of the pole-type holder 10. It should be noted that openings may be provided at positions corresponding to the waterproof microphones 2d and 2d (not shown) on both side surfaces of the mount portion 11a so that the waterproof microphones 2d and 2d can collect sound.

  As shown in FIG. 12 (A), a U-shaped leaf spring 11f having a substantially U-shaped tip is incorporated in the lower inner surface of the mount portion 11a so as to be able to appear and retract. Further, a U-shaped groove 2p is formed on the front side of the lower surface of the waterproof imaging terminal 2. Further, a mounting recess 11d is provided on the upper inner surface of the mount portion 11a, and the upper surface portion of the first antenna portion 4b is accommodated in the mounting recess 11d. And the compression part 11e comprised with a flexible elastomer, a foamed urethane sheet, etc. is provided so that the upper inner surface of the mount part 11a and the lower surface part of the 1st antenna part 4b may be covered.

  As shown in FIG. 12A, the lower surface portion of the first antenna portion 4b slightly protrudes downward from the upper inner surface of the mount portion 11a. Therefore, when the compression portion 11e is covered, the portion of the first antenna portion 4b bulges downward in the compression portion 11e as much as the first antenna portion 4b protrudes. The dimension D from the lower surface of the bulging part of the compression part 11 e to the lower inner surface of the mount part 11 a is configured to be slightly smaller than the vertical dimension E of the waterproof imaging terminal 2. When the waterproof imaging terminal 2 is inserted into the imaging terminal mount 11 in the direction of the arrow, the bulging portion of the compression portion 11e is crushed and compressed by the upper surface portion of the case 2a of the waterproof imaging terminal 2.

  As shown in FIG. 12B, in a state where the waterproof imaging terminal 2 is mounted on the imaging terminal mount 11, the U-shaped leaf spring 11f is fitted into the U-shaped groove 2p, and the waterproof imaging terminal 2 is Held in place. Further, the entire waterproof imaging terminal 2 is biased upward by the U-shaped leaf spring 11f. Then, the urging force of the U-shaped leaf spring 11f is further applied, and the bulging portion of the compression portion 11e is crushed and compressed by the upper surface portion of the case 2a of the waterproof imaging terminal 2. In this way, the first antenna unit 4b and the waterproof imaging terminal 2 are joined in a watertight manner through the compressed and compressed unit 11e that has been crushed and compressed.

In addition, you may make it cover the cover sheet mentioned later on the lower surface side of the compression part 11e. By covering the cover sheet, the surface becomes smoother, the waterproof imaging terminal 2 can be easily inserted, and the adhesion of the waterproof imaging terminal 2 to the case 2a can be improved.
Moreover, as a structure of the attaching part 11b, you may comprise in the structure which is tied to the pole-type holder 10 or pinched and fixed.

Next, the portable terminal mount 12 will be described.
Like the waterproof imaging terminal 2, the second antenna portion 4c is not directly joined to the case 2a of the mobile terminal 3 or the waterproof case 7 for mobile terminal, but is incorporated in the mount 12 for mobile terminal. ing. And the 2nd antenna part 4c is comprised so that the portable terminal 3 may be joined by attaching the portable terminal 3 to the mount 12 for portable terminals.

  As shown in FIG. 11, the mobile terminal mount 12 is a holder mount that holds the mobile terminal 3. That is, the mobile terminal mount 12 includes a mount part 12a that holds the left part, the right part, and the lower part of the mobile terminal 3, and an attachment part 12b that is integrally formed on the front surface of the mount part 12a. An attachment hole (not shown) is formed in the attachment portion 12b, and is configured to be detachable from the upper holding portion 10g of the upper arm portion 10e of the pole-type holder 10.

  Similarly to the case of the first antenna portion 4b, the second antenna portion 4c is attached so as to slightly protrude from the rear surface of the mount portion 12a, and the surface thereof is covered with a compression portion (not shown). In the compression unit, the portion of the second antenna portion 4c bulges in the rearward direction as much as the second antenna portion 4c protrudes. When the portable terminal 3 is inserted into the portable terminal mount 12 in the direction of the arrow, the bulging portion of the compression portion is crushed and compressed by the front surface portion of the case 3a of the portable terminal 3. Thus, the 2nd antenna part 4c and the portable terminal 3 join watertightly through the compression part which was crushed and compressed.

  Here, when the portable terminal 3 is a waterproof type, the second antenna portion 4c and the portable terminal 3 are joined in a watertight manner, and therefore can be used even underwater. That is, the underwater wireless LAN communication system 1 including the pole holder 10 can be used underwater. Further, the imaging terminal mount 11 and the portable terminal mount 12 may be configured so that they can be mounted in a state of being accommodated in the imaging terminal waterproof case 6 and the portable terminal waterproof case 7. It can be used in deeper water.

  In addition, when the portable terminal 3 cannot be submerged, it is not necessary to form a watertight structure, and therefore the compression part of the portable terminal mount 12 may be omitted. Further, the mounting position of the second antenna portion 4c of the mobile terminal mount 12 is arranged at a position substantially opposite to the mobile terminal antenna portion 3e or in the vicinity thereof. However, if communication sensitivity can be obtained, the mobile terminal 3 You may provide in the position adjacent to, a position a little apart, etc. Also, in the case of the imaging terminal mount 11, if the communication sensitivity can be obtained even in the water by simply bringing the first antenna part 4b and the imaging terminal antenna part 2e into close contact with each other without watertight, it is waterproof. The foam sheet 11e may be omitted.

  With the above configuration, wireless LAN signal communication between the waterproof imaging terminal 2 and the portable terminal 3 via the communication cable 4 is possible even when the waterproof imaging terminal 2 or both are underwater. It was. Since the communication cable 4 is incorporated in the imaging terminal mount 11 and the portable terminal mount 12, there is no need to make holes in the case bodies 6a and 7a, and the waterproof performance can be maintained as it is. It became.

  In addition, the pole-shaped holder 10 makes it possible to handle the entire underwater wireless LAN communication system 1 as one body, improving usability. In addition, since the communication cable 4 directly transmits the wireless LAN signal between the one and the other antenna without converting the signal, the number of parts is small, and a simple configuration can be manufactured at a low cost. It was.

(Sixth embodiment)
With reference to FIGS. 13A and 13B, a sixth embodiment of the present invention will be described.
The sixth embodiment has the same configuration as the fifth embodiment, has the same function, and has the same effect. This embodiment is different from the fifth embodiment in that the structure for joining the first antenna portion 4b to the case 2a of the waterproof imaging terminal 2 in the imaging terminal mount 11 (holding device) is different. . Hereinafter, the same parts as those of the fifth embodiment are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.

The imaging terminal mount 11 will be described.
Here, the first antenna portion 4b of the present embodiment is incorporated in the imaging terminal mount 11 and attached to the waterproof imaging terminal 2 in the same manner as in the fifth embodiment. It is comprised so that it may join.
A U-shaped leaf spring 11f whose tip is U-shaped is incorporated in a lower inner surface of the mount portion 11a of the imaging terminal mount 11 so as to be able to appear and retract. Further, a U-shaped groove 2p is formed on the front side of the lower surface of the waterproof imaging terminal 2.

  As shown in FIG. 13A, on the upper inner surface of the mount portion 11a, a layered compression portion 11e made of a flexible elastomer, a foamed urethane sheet or the like is provided. The first antenna portion 4b is disposed substantially at the center of the lower surface of the compression portion 11e, and the lower surface portions of the compression portion 11e and the first antenna portion 4b are made of a nonconductive material such as a thin resin film. The cover sheet 11g which consists of is provided so that it may cover. Here, the portion of the first antenna portion 4b bulges downward in the cover sheet 11g covered by the thickness of the first antenna portion 4b.

  As shown in FIG. 13A, the dimension D from the lower surface of the bulging part of the cover sheet 11g to the lower inner surface of the mount part 11a is configured to be slightly smaller than the vertical dimension E of the waterproof imaging terminal 2. ing. When the waterproof imaging terminal 2 is inserted into the imaging terminal mount 11 in the direction of the arrow, the bulging portion of the cover sheet 11g is pushed upward by the upper surface portion of the case 2a of the waterproof imaging terminal 2, and the compression portion 11e is It is crushed and compressed.

  As shown in FIG. 13B, in a state where the waterproof imaging terminal 2 is mounted on the imaging terminal mount 11, the U-shaped leaf spring 11f is fitted into the U-shaped groove 2p, and the waterproof imaging terminal 2 is Held in place. Further, the entire waterproof imaging terminal 2 is biased upward by the U-shaped leaf spring 11f. Then, the urging force of the U-shaped leaf spring 11f is further applied, and the bulging portion of the cover sheet 11g is pushed in by the upper surface portion of the case 2a of the waterproof imaging terminal 2, and the compression portion 11e is crushed and compressed. Thus, the first antenna portion 4b and the waterproof imaging terminal 2 sandwich the cover sheet 11g with the urging force of the compressed and compressed portion 11e and the urging force of the U-shaped leaf spring 11f. It is in pressure contact.

Here, due to an impact or the like, a force for peeling the first antenna portion 4b from the waterproof imaging terminal 2 works, and there is a possibility that the first antenna portion 4b is separated for a moment in water. If they are separated, water enters between the outer surface of the first antenna portion 4b and the case 2a. Here, since the elastic force of the protective cover 8 for the imaging terminal is working, the first antenna portion 4b and the case 2a immediately move so as to be in close contact with each other, so that the water between the two is eliminated and the water tightness is again obtained. Return to the state of joining.

  However, there is a possibility that the water between the first antenna portion 4b and the case 2a cannot be completely removed, and a thin layer of water may remain in some portions. Here, it should be noted that radio waves are not shielded and shielded by water, but are absorbed by water and greatly attenuated by increasing distance in water. Radio waves are absorbed by the thin water layer between the outer surface of the first antenna portion 4b and the case 2a, but the distance is small, and there is little influence on the wireless LAN communication. it can.

  In the present embodiment, the first antenna unit 4b and the waterproof imaging terminal 2 are configured to be pressed against each other by the urging force of the compression unit 11e and the urging force of the U-shaped leaf spring 11f. It is not limited. For example, a lock part may be provided instead of the U-shaped plate spring 11f, and the waterproof imaging terminal may be held at a predetermined position of the imaging terminal mount 11 by the lock part. In this case, the urging force of the U-shaped plate spring 11f does not work, but the urging force of the compression part 11e works, and the first antenna part 4b and the case 2a are in close contact with each other.

  Further, the cover sheet 11g is rubbed and rubbed when the waterproof imaging terminal 2 is pushed in. For this reason, as the resin film used for the cover sheet 11g, for example, a strong, scratch-resistant film having a smooth surface, such as a film made of a PET (polyethylene terephthalate) resin, is preferable. Moreover, by covering the cover sheet 11g, the surface becomes smoother and the adhesion between the waterproof imaging terminal 2 and the case 2a can be improved.

  Further, the imaging terminal mount 11 and the portable terminal mount 12 shown in the fifth and sixth embodiments are examples of mounts for wireless LAN devices, and an antenna unit can be incorporated into various types of mounts. it can. For example, when the pedestal mount mounting portion is provided on the lower surface side of the waterproof case 6 for the imaging terminal and the pedestal mount incorporating the antenna portion is attached, the antenna portion may be pressed and joined.

(Seventh embodiment)
A seventh embodiment of the present invention will be described with reference to FIGS. 14 (A), (B), and (C).
The seventh embodiment is a communication cable 4 used in the underwater wireless LAN communication system 1 and has the same function as the communication cable 4 shown in the first embodiment. The present embodiment relates to a communication cable 4 in which a film antenna is manufactured by film insert molding. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.

  FIG. 14A is a perspective view showing the first antenna portion 4b or the second antenna portion 4c (hereinafter, referred to as antenna portions 4b and 4c) of the communication cable 4. FIG. FIG. 14B is an enlarged view of a part of the sectional view taken along the line G-G in FIG. 14A, and is a schematic diagram showing details of the film antenna 4j that is the antenna body 4d. . FIG. 14C shows a situation when the antenna portions 4b and 4c of the communication cable 4 are manufactured, and the cross sections of the antenna portions 4b and 4c are taken along line GG in FIG. 14A. A part of the sectional view in the direction is shown.

The antenna units 4b and 4c will be described.
As shown in FIG. 14A, the antenna parts 4b and 4c are manufactured by film insert molding, and have a film antenna 4j on the surface, then a resin layer 4k, and an adhesive part 4h on the back surface. The adhesive portion 4h is formed by sticking an adhesive sheet or the like after the antenna portions 4b and 4c are molded. The user U can visually recognize the antenna layer 4p and the printed layer 4q formed on the back surface of the film antenna 4j through the transparent base film layer 4n of the film antenna 4j.

As shown in FIG. 14B, the film antenna 4j is formed such that the antenna layer 4p and the printed layer 4q are formed on the back surface of the base film layer 4n, and the entire back surface is covered with the protective layer 4r. ing. The base film layer 4n is made of a transparent resin film such as a PET (polyethylene terephthalate) resin or a polycarbonate resin. The antenna layer 4p is made of a metal thin film such as copper or aluminum, and the printed layer 4q is for decoration and is printed with characters and designs. The protective layer 4r serves as a binder for protecting the antenna layer 4p and the printed layer 4q and firmly bonding the film antenna 4j and the resin layer 4k during molding.

  Here, the printing layer 4q may be formed from the same metal thin film as the antenna layer 4p without using ink or the like. In the step of forming the antenna layer 4p, the printed layer 4q can be formed at the same time, so the number of steps is reduced and the cost is greatly reduced. The antenna needs to have a shape for communicating a wireless LAN signal, but may have a shape having both communication performance and design. By arranging and forming characters and designs in a space where no antenna is formed, the overall design can be improved.

  If a resin having high rigidity such as polycarbonate resin or ABS resin is used as the resin used for the resin layer 4k, a resin having high rigidity and durability can be formed. In addition, if a flexible elastomer resin or the like is used, flexible antenna portions 4b and 4c are formed, and even when the case of the wireless LAN device is a curved surface, it can be joined so that it fits exactly. .

  As shown in FIG. 14C, the antenna parts 4b and 4c are formed by film insert molding. That is, the film antenna 4j is mounted on one side of the mold M with the antenna layer 4p facing the resin layer 4k side, the mold M is closed, and the molten resin is injected and molded together with the resin layer 4k. The cable portion 4a connected to the antenna layer 4p is simultaneously enclosed in the resin layer 4k.

  Here, the film antenna 4j may be formed before forming. For example, in the antenna portions 4b and 4c shown in FIG. 14A, the film antenna 4j has a planar shape, but it can be formed into a gentle shape by rounding the four sides by forming. In addition, it is possible to make irregularities on characters and antennas. By performing the forming process in this manner, the design properties as a whole can be improved.

  By configuring as described above, the antenna portions 4b and 4c of the communication cable 4 can be configured to have both functions and design properties. Film insert molding has already been technically established, and it has become possible to stably manufacture a communication cable 4 having high design properties.

(Eighth embodiment)
With reference to FIGS. 15A and 15B, an eighth embodiment of the present invention will be described.
The eighth embodiment is a communication cable 4 used in the underwater wireless LAN communication system 1, and has the same function as the communication cable 4 shown in the first embodiment. The present embodiment relates to a communication cable 4 manufactured by resin sealing, and a portion of the adhesive portion 4h (joint portion, adhesive portion) is configured to be simultaneously formed by resin sealing. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.

  FIG. 15A is a perspective view showing the antenna portions 4b and 4c with the adhesive portion 4h facing upward in the communication cable 4. FIG. FIG. 15 (B) shows the situation when the antenna parts 4b and 4c are manufactured by resin sealing, and the cross sections of the antenna parts 4b and 4c are taken in the direction of arrows HH in FIG. 15 (A). FIG.

The manufacturing method and configuration of the antenna units 4b and 4c will be described.
As shown in FIGS. 15A and 15B, the antenna portion 4b is manufactured by injecting a sealing resin into the outer case portion 4s to form a sealing resin portion 4t. . The outer case portion 4s has a tray shape in which the upper surface direction of the thin square box is released, and is made of resin.

  That is, first, the antenna body 4d is fixed to a predetermined position on the inner bottom portion of the outer case portion 4s by the adhesive tape 4u or the like. Next, the cable portion 4a connected to the antenna body 4d is fitted and fixed in the cable attachment groove 4v formed on one side of the outer case portion 4s. Finally, the melted elastomer resin is poured into the outer case portion 4s by the nozzle N or the like, and the antenna body 4d and the cable portion 4a are sealed.

  As shown in FIGS. 15A and 15B, a predetermined amount of the elastomer resin that is the sealing resin portion 4t is poured so as to rise from the end portion of the outer case portion 4s due to surface tension. Here, this elastomer resin becomes a gel when solidified, and has an adhesive property and a re-peelable property. That is, the raised upper surface of the sealing resin portion 4t can be used as the adhesive portion 4h.

  Here, if a resin having high rigidity, such as polycarbonate resin or ABS resin, is used as the resin forming the outer case portion 4s, the rigidity becomes high and durable. Further, if a flexible antenna resin is used and a film antenna or a formed flexible wire is used for the antenna portion 4b, the flexible and flexible antenna portions 4b and 4c can be formed.

  In addition, as shown to FIG. 15 (A) and (B), although the cable 4 for communication of this embodiment has shown the structure which does not attach the cable protection bush part 4g, it is not limited to this. For example, by forming a cable attachment groove 4v that matches the attachment portion of the cable protection bush portion 4g in the outer case portion 4s, it is possible to attach a cable protection bush portion 4g that is a separate part.

  By configuring as described above, the adhesive portions 4h of the antenna portions 4b and 4c can be simultaneously formed by sealing with the sealing resin portion 4t without using another component such as an adhesive sheet. Become. It is possible to reduce the number of parts in manufacturing the communication cable 4 and simplify the manufacturing process, and it is possible to easily manufacture the communication cable 4 without cost. In addition, it has become possible to manufacture using a mold having a simple structure and a lower cost than a mold used for insert molding or film insert molding.

  In the first to eighth embodiments described above, an example of the Wi-Fi (registered trademark) standard has been given as the standard for wireless LAN communication. However, any wireless LAN communication standard with which a wireless LAN device can communicate is used. For example, it is not limited to this. Further, the present invention is not limited to wireless LAN communication. It can be applied to various wireless devices. Also, the position of the wireless LAN communication antenna built in the wireless LAN device is just an example, and is not limited thereto.

Further, although the loop antenna is used as the antenna body, the form of the antenna is not limited as long as wireless LAN signals can be communicated. For example, a T-shaped antenna or a bar antenna may be used. Moreover, although the antenna part is a substantially rectangular plate-shaped flat shape, it is not limited to this. For example, it may be a disk shape, a donut-shaped ring shape, an oval shape, a long bar shape, or the like.
Here, in the case of mounting on a flat case, it is preferable that the shape of the antenna portion is a flat plate for ease of mounting.

  In addition, although the antenna portion is sealed with resin, the present invention is not limited to this. For example, the antenna body may be configured by fixing and arranging the antenna main body in the hollow portion of the resin container using a watertight hermetically sealed hollow resin container.

  In addition, the position where the antenna portion of the communication cable is joined is set to a position substantially facing the antenna portion of the wireless LAN device or in the vicinity thereof, but this is because stronger sensitivity is obtained, and the joining position is not limited to this. . If the joint position is practically capable of wireless LAN communication, the joint position becomes wide, and may be joined to another part.

Here, in the case of a wireless LAN device that is not used underwater, the wireless LAN device can be used even if it is disposed adjacent to the wireless LAN device without joining the antenna unit. This is because radio waves are absorbed by water in water but not in the air.
In addition, although the two antenna portions provided at both ends of the communication cable have the same shape and configuration, the present invention is not limited to this, and one antenna portion may have a different shape from the other.

  For example, the antenna unit used for a portable terminal that is not used underwater may be configured to be attached to a position immediately below the lower surface of the portable terminal as a long, cylindrical or prismatic rod having a different shape from the other. Here, the length of the rod-shaped antenna unit is configured to be slightly shorter than the length of the mobile terminal in the left-right direction (long side direction). In addition, as an attachment method of an antenna part, an elongate thin board is fixed along the longitudinal direction of a rod-shaped antenna part, for example. Then, an adhesive portion is provided on one surface of the thin plate, and the thin plate adhesive portion is attached to the lower surface side of the front surface of the portable terminal. In such a configuration, since the antenna unit is located adjacent to the mobile terminal, wireless LAN communication can be performed. Moreover, since the antenna part is located along the lower surface part of the portable terminal, it is difficult to disturb the handling.

  Further, the coaxial cable used for the cable portion may be one provided with one or a plurality of shield layers with aluminum foil or the like. This is to prevent unnecessary radiation. Moreover, it is preferable to use a cable part whose outer skin etc. are strong in water resistance, seawater resistance etc., and may use a cable strong in impact resistance as needed.

  In addition, as a configuration of a joint portion (joint portion) between the antenna portion and the case of the wireless LAN device, a configuration in which an adhesive portion is provided on the antenna portion and a joint portion, and a configuration in which the antenna portion and the like are urged to be in close contact with the case Although shown, it is not limited to this. For example, the joining portion may be configured by providing a sucker on the antenna portion or arranging a magnet or the like that attracts the antenna portion and the case to each other. In the case where the antenna unit is configured with a suction cup, the height of the protrusion when the antenna unit is attached to the outer shell is increased.

In addition, the underwater wireless LAN communication system of the present invention is configured such that at least a wireless LAN signal can be sent from the first wireless LAN device in the water to the second wireless LAN device via the underwater LAN communication cable. Of course, communication is possible as well as transmission. An underwater wireless LAN communication system that can communicate with each other can also be expressed as follows.
A first wireless LAN device that transmits and receives wireless LAN signals in water, a second wireless LAN device that transmits and receives wireless LAN signals, and a wireless LAN signal between the first wireless LAN device and the second wireless LAN device In the underwater wireless LAN communication system including the underwater LAN communication cable for transmitting the first wireless LAN device, the first wireless LAN device is disposed in the first outer shell body having a watertight structure and the first outer shell body. A first wireless LAN unit that transmits and receives wireless LAN signals, and the second wireless LAN device is disposed inside the second outer shell and inside the second outer shell and transmits and receives wireless LAN signals. The underwater LAN communication cable has a watertight structure for receiving and transmitting a wireless LAN signal transmitted and received by the first wireless LAN unit by being watertightly joined to the first outer shell body. 1 antenna part and 2nd outside A second antenna unit joined directly or adjacent to the body and having a watertight structure for receiving and transmitting a wireless LAN signal transmitted and received by the second wireless LAN unit; and one antenna connected to the first antenna unit and having two antennas The other end is connected to the part, and a transmission cable part for directly transmitting the wireless LAN signal between the first antenna part and the second antenna part through the electric wire is provided.

  Further, the underwater wireless LAN communication system and the underwater wireless LAN communication cable of the present invention are not limited to the embodiments described above and shown in the drawings, and various modifications may be made without departing from the scope of the invention. Is possible.

  For example, in the above-described embodiment, an example in which the wireless LAN device is applied to a waterproof imaging terminal (waterproof digital camera) and a mobile terminal (smartphone) is described. It can be applied to notebook computers, digital cameras, portable game machines, mobile phones, portable information terminals, digital cameras, portable game machines, portable audio players, tablet terminals, and other wireless LAN devices. Further, the present invention can be applied to a so-called wearable terminal such as a wristwatch type terminal or an HMD (head mounted display).
