Description

  The present invention relates to a lightning protection connection method, and more particularly to a lightning protection connection method for connecting a lightning protection device and a multi-function communication terminal.

  With the spread of the Internet, HGW devices (home gateway devices) are installed in each home, and the number of users who use VoIP (Voice over Internet Protocol) telephones is increasing.

  A device having an analog port compatible with a VoIP phone, such as an HGW device, is not limited to a telephone terminal that operates only by power supply (power supply, power transmission) from the telephone line side, but also an answering machine or FAX ( In many cases, a multifunctional communication terminal that requires power supply from the power line side is connected because it has a function other than a telephone call.

  The multi-function communication terminal has its own power source in order to operate functions other than calls.

  Normally, multi-function communication terminals are designed to prevent lightning surges, so that lightning surges applied to the power line are bypassed to the telephone line (communication line), and conversely lightning surges applied to the telephone line are bypassed to the power line. It has become.

  This was good when the telephone line of the multi-function communication terminal was connected to the public switched telephone network, but there was a problem when it was connected to the analog port of the HGW device as a VoIP telephone terminal.

  For example, a lightning surge that is bypassed from the power source of the multi-function communication terminal to the telephone line side is directly applied to the analog port of the HGW device. Therefore, a multi-function communication terminal such as an answering machine or FAX connected to the HGW product is used. Increasingly, lightning surge is applied to the analog port of the HGW device from the power source via the telephone line, the HGW device is destroyed, and the HGW device is returned as a failure.

  Although the current HGW apparatus incorporates lightning countermeasures, it is necessary to have a resistance to a large lightning surge and a path (passage) for releasing the lightning surge. In particular, in Japan, it is a connection of a power supply system called a TT system, and a protective ground conductor is not supplied together with a power line. The first character “TT” indicates the relationship between the power system and the ground, and the first character “T” indicates that “one point is directly connected to the ground”. The second letter “TT” indicates the relationship between the exposed conductive portion of the equipment and the ground, and the second letter “T” indicates “the exposed conductive portion directly on the ground regardless of the ground of the power system. Indicates to be “grounded”. In the TT system, the protective installation of the device and the protective ground of the power system are connected to independent protective grounds, so that they are not completely at the same potential, causing a lightning surge to flow.

  Furthermore, since a general household outlet has two poles and does not have a protective ground terminal in most cases, a lightning surge cannot be released to the protective ground. That is, a device such as an HGW device has been affected by a lightning surge because there is no path for escaping the lightning surge.

  The problem described above will be described in detail below.

  FIG. 1 shows a lightning surge bypass method applied between a telephone line and a commercial power line of a general communication terminal.

  An SPD (Surge Protect Device) is disposed on each of the commercial power line and the telephone line. The SPD is an element that is turned on (ON) when a voltage higher than a specified voltage is applied, and that shorts the line between the commercial power line and the telephone line. Further, the SPD is turned off (OFF) in normal times (when the applied voltage is within a specified range), and the line between the commercial power line and the telephone line is opened (opened). As examples of SPDs, thyristors, varistors, arresters and the like are known. The SPD may be a surge absorber.

  Here, SPD1 to SPD3 are arranged on the commercial power line. Further, SPD4 to SPD6 are arranged on the telephone line. Further, the midpoint of SPD2-SPD3 and the midpoint of SPD5-SDP6 are connected.

  By doing so, when a lightning surge is applied to the commercial power line, SPD2, SPD3, SPD5, and SPD6 are turned on, and the lightning surge can be bypassed to the telephone line side. In FIG. 1, a path indicated by a dotted line is a lightning surge path.

  Conversely, when a lightning surge is applied from the telephone line, it is similarly bypassed to the commercial power line side.

  That is, a multi-function communication terminal such as an answering machine or FAX has a built-in circuit for bypassing lightning surge by SPD as shown in FIG.

  There was no problem when such a communication terminal was directly connected to the public switched telephone network, but when it was connected to the analog port of the HGW device, this bypassed lightning surge was applied to the analog port of the HGW device. Since the voltage is directly applied, there is a problem that the HGW device is destroyed.

  In order to avoid such a problem, a device called an external type lightning protection device disposed between a communication terminal and a telephone line has already been developed and sold. In general, such a lightning protection device is called a thundercut, a lightning guard or the like composed of surge countermeasure parts. As examples of lightning protection devices, lightning arresters, circuit breakers, lightning resistant transformers (lightning resistant transformers), stub filters, surge protectors, and the like are known.

  However, there are few users who install such a lightning protection device until purchase, and even if it is installed, there is a problem that if the connection is wrong, the effect cannot be obtained sufficiently. That is, there is a problem that the lightning protection device and the HGW device must be correctly connected.

  Patent Documents 1-4 also propose countermeasures against various lightning surges, but no concrete countermeasures for reliably connecting the lightning protection device have been proposed so far.

[Connection method of conventional lightning protection device and HGW device]
Below, the connection method of the conventional lightning protection apparatus and HGW apparatus is demonstrated.

  As shown in FIG. 2, in the conventional lightning protection connection method (lightning protection connection system), the lightning protection device 10 includes an HGW device 20, an AC outlet 30, a telephone 40, and an AC outlet 50.

  The lightning protection device 10 is connected to the HGW device 20, the AC outlet 30, and the telephone set 40 in a connection form as shown in FIG. The telephone 40 is connected to an AC outlet 50.

  The lightning protection device 10 includes an AC outlet 11, an AC plug 12, a modular connector 13, and a modular connector 14.

  The AC outlet 11 is connected to the HGW apparatus 20 via a commercial power line. AC plug 12 is connected to AC outlet 30 via a commercial power line. The modular connector 13 is connected to the HGW apparatus 20 via a telephone line. The modular connector 14 is connected to the telephone 40 via a telephone line. Each of the modular connector 13 and the modular connector 14 has an analog port.

  SPD 1 to SPD 3 are connected to the AC outlet 11. SPD 4 to SPD 6 are connected to the modular connector 13 and the modular connector 14. Here, SPD 4 to SPD 6 are arranged between the modular connector 13 and the modular connector 14. Further, the midpoint of SPD2-SPD3 and the midpoint of SPD5-SDP6 are connected.

  The HGW apparatus 20 includes a modular connector 21 and an AC plug 22.

  The modular connector 21 is connected to the modular connector 13 via a telephone line. The modular connector 21 has an analog port. The AC plug 22 is connected to the AC outlet 11 via a commercial power line.

  Although not shown, since an electronic circuit generally uses a direct current (DC), an AC-DC conversion circuit (along with an AC plug 22) is used to supply power from a household power source supplied as an alternating current (AC). AC-DC converter (AC-DC converter) is arranged. Here, it is assumed that the AC-DC conversion circuit is integrated with the AC plug 22. The AC plug 22 may be an AC adapter. That is, the AC-DC conversion circuit may be attached to the outside of the HGW apparatus 20 as an AC adapter together with the AC plug 22.

  The telephone 40 includes an AC plug 41.

  The AC plug 41 is connected to the AC outlet 50 by a commercial power line.

  The problem here is that the expected effect cannot be obtained unless the correct connection as shown in FIG. 2 is made.

  For example, the AC plug 22 needs to be connected to the AC outlet 11. This is because if the AC plug 22 is connected to another AC outlet (not shown), if a lightning surge is applied to the AC outlet, it cannot be bypassed to the telephone line, and the HGW device is broken. Because it will end up.

  Below, the possible wiring states are listed, and what kind of wiring mistakes are considered is considered.

  (1) “The telephone 40 is directly connected to the modular connector 21 of the HGW device 20 without going through the lightning protection device 10, and the AC plug 22 of the HGW device 20 is connected to an AC outlet other than the AC outlet 11 of the lightning protection device 10. State

  In this case, since the lightning protection device 10 is not used at all, the lightning surge cannot be reliably protected.

  (2) “Telephone 40 is correctly connected to the modular connector 21 of the HGW device 20 via the lightning protection device 10, and the AC plug 22 of the HGW device 20 is correctly connected to the AC outlet 11 of the lightning protection device 10. The AC plug 12 of the lightning protection device 10 is not connected to the AC outlet 30 "

  In this case, the AC plug 22 of the HGW device 20 is correctly connected to the AC outlet 11 of the lightning protection device 10, but no power is supplied from the AC outlet 30 to the lightning protection device 10. Since no power is supplied to 20 and the HGW device 20 is not turned on (the HGW device 20 does not start), there is no problem with lightning surge.

  (3) “The telephone 40 is correctly connected to the modular connector 21 of the HGW device 20 via the lightning protection device 10, but the AC plug 22 of the HGW device 20 is an AC outlet other than the AC outlet 11 of the lightning protection device 10. And the AC plug 12 of the lightning protection device 10 is not connected to the AC outlet 30 "

  In this case, power is not supplied from the AC outlet 30 to the lightning protection device 10, but power is supplied directly from the AC outlet other than the AC outlet 11 of the lightning protection device 10 to the HGW device 20, so the HGW device 20 operates. The telephone 40 can also be used. On the other hand, since the AC plug 22 of the HGW device 20 is not normally connected to the AC outlet 11 of the lightning protection device 10, it is not possible to reliably protect against a lightning surge. As described above, if a lightning surge is applied to the AC outlet to which the AC plug 22 of the HGW device 20 is connected, the HGW device 20 may be broken because it cannot be bypassed to the telephone line side. Because there is.

  (4) “The telephone 40 is correctly connected to the modular connector 21 of the HGW device 20 via the lightning protection device 10, and the AC plug 12 of the lightning protection device 10 is correctly connected to the AC outlet 30. The AC plug 22 is connected to an AC outlet other than the AC outlet 11 of the lightning protection device 10.

  In this case, since the power is supplied to the HGW device 20 from the AC outlet other than the AC outlet 11 of the lightning protection device 10 as in the state (3), the HGW device 20 and the telephone 40 can be used. Become. On the other hand, since the AC plug 22 of the HGW device 20 is not normally connected to the AC outlet 11 of the lightning protection device 10, it is not possible to reliably protect against a lightning surge.

  (5) “The telephone 40 is correctly connected to the modular connector 21 of the HGW device 20 via the lightning protection device 10, the AC plug 12 of the lightning protection device 10 is correctly connected to the AC outlet 30, and the AC plug of the HGW device 20 is 22 is correctly connected to the AC outlet 11 of the lightning protection device 10 "

  In this case, there is no problem because the connection is normal. That is, it will be in the state which can be reliably protected against a lightning surge.

  As described above, there has been a problem that unless the lightning protection device and the HGW device are correctly connected, they cannot be reliably protected from lightning surge.

  The modular plug 16 is a modular plug for connecting to the analog port of the modular connector of the HGW apparatus 20. The modular plug is only an example. Actually, other standard plugs such as a LAN plug and a USB plug may be used.

  The protrusion 17 physically presses a switch (SW) in the HGW device 20 to turn it on. The shape of the protrusion 17 is not questioned. The protrusion 17 may be movable. In actuality, the protrusion 17 may be one that electrically energizes a circuit corresponding to a switch (SW) in the HGW device 20. Further, the protrusion 17 may be one that joins / fits the lightning protection device 10 and the HGW device 20. That is, the protrusion 17 may be any switch that turns on the switch (SW) in the HGW device 20 in accordance with the physical approach / contact between the lightning protection device 10 and the HGW device 20.

  An SPD circuit (circuit formed by SPD) for bypassing lightning surge is provided between the modular connector 14, the AC outlet 11, and the modular plug 16. The SPD may be a surge absorber.

  SPD 1 to SPD 3 are connected to the AC outlet 11. SPD 4 to SPD 6 are connected to the modular connector 14 and the modular plug 16. Here, SPD 4 to SPD 6 are arranged between the switch (SW) 15 and the modular plug 16. Further, the midpoint of SPD2-SPD3 and the midpoint of SPD5-SDP6 are connected. In practice, SPD 4 to SPD 6 may be arranged between the modular connector 14 and the switch (SW) 15.

  FIG. 4 shows an appearance image of the lightning protection device 10.

[Supplement of modular plug 16 and protrusion 17]
Although not essential, the modular plug 16 may be configured to be connected to the analog port of the modular connector of the HGW device 20 and at the same time, the protrusion 17 may turn on the switch (SW) in the HGW device 20. Is possible. For example, the modular plug 16 and the protrusion 17 may be integrated, or the modular plug 16 and the protrusion 17 may be interlocked. It is also possible to attach the protrusion 17 to the modular plug 16 itself.

  Thereby, the modular plug 16 and the protrusion 17 can be configured to expand and contract at the same time, and the modular plug 16 and the protrusion 17 can be extended from the main body of the lightning protection device 10.

  In addition, a plurality of sets of the modular plug 16 and the protrusion 17 can be prepared, and the lightning protection device 10 can be connected to the plurality of HGW devices 20. In this case, a set of the modular plug 16 and the protrusion 17 is connected to one HGW apparatus 20 per set.

  That is, the number of HGW devices connected to the lightning protection device is not limited to one and may be plural. In this case, the lightning protection device 10 includes an AC outlet 11, an AC plug 12, a modular connector 14, and a switch (SW) 15 for each of the plurality of HGW devices 20 (for each connected HGW device 20). Assume that a set of a modular plug 16 and a protrusion 17 is disposed.

[Configuration example of HGW device]
The HGW apparatus 20 includes a modular connector 21, an AC plug 22, a switch (SW) 23, a CPU (Central Processing Unit) 24, an alarm lamp 25, a speaker 26, and a network adapter 27.

  The modular connector 21 has an analog port for connecting the modular plug 16 of the lightning protection device 10. The modular connector is only an example. Actually, other standard connectors such as a LAN connector and a USB connector may be used. However, the modular connector 21 is necessarily paired with the modular plug 16. That is, the shape of the analog port of the modular connector 21 can be joined to the modular plug 16.

  The AC plug 22 is an AC plug of the power supply device of the HGW device 20. The AC plug 22 is connected to the AC outlet 11 of the lightning protection device 10 by a commercial power line. The AC plug 22 receives alternating current (AC) from the AC outlet 11 through the commercial power line.

  Although not shown, in general, since the electronic circuit inside the HGW device 20 uses direct current (DC), in order to supply power from a household power source supplied as alternating current (AC), together with the AC plug 22 An AC-DC converter circuit (AC-DC converter: AC-DC converter) is arranged. Here, it is assumed that the AC-DC conversion circuit is integrated with the AC plug 22. The AC plug 22 may be an AC adapter. That is, the AC-DC conversion circuit may be attached to the outside of the HGW apparatus 20 as an AC adapter together with the AC plug 22.

  The switch (SW) 23 is turned on by the protrusion 17 when the lightning protection device 10 is connected. Here, the switch (SW) 23 is grounded (GND) when turned on by the protrusion 17. Note that grounding (GND) is merely an example. Actually, the switch (SW) 23 may be connected to the power supply terminal (VDD) or the like when turned on by the protrusion 17. Accordingly, the switch (SW) 23 outputs a detection signal 231 whose potential state changes according to the connection of the lightning protection device 10.

  The CPU 24 is connected to other internal components of the HGW device 20 such as a storage device and a power supply device via a cable and a board. The CPU 24 detects the detection signal 231 from the switch (SW) 23 when the switch (SW) 23 is turned on by the protrusion 17.

  The alarm lamp 25 notifies the user of an alarm (warning) by light emission (lighting, blinking, etc.) and alerts the user.

  The speaker 26 notifies the user of an alarm (warning) and alerts the user by voice output (voice guidance, beep sound, etc.).

  The network adapter 27 notifies the connection state of the lightning protection device 10 in the HGW device 20 to the base station or the server via the public line network. As an example of the network adapter 27, a network interface card (NIC), a similar expansion card, or a wireless communication device conforming to a communication standard of a mobile phone or PHS can be considered.

[Supplement of network adapter]
Although not essential, the network adapter 27 is preferably connected to the public network via a lightning protection device different from the lightning protection device 10. The network adapter 27 may be a modular connector different from the modular connector 21. The network adapter 27 may be shared with the modular connector 21, but in this case, the connection state of the lightning protection device 10 to the base station or the server only when the lightning protection device 10 and the HGW device 20 are correctly connected. Will be notified.

[Supplement of HGW equipment]
Although not essential, the AC plug 22 of the HGW device 20 is connected to the AC outlet 11 of the lightning protection device 10, and at the same time, the protrusion 17 of the lightning protection device 10 turns on the switch (SW) 23 of the HGW device 20. It is also possible to configure so as to. For example, when the AC plug 22 of the HGW device 20 is connected to the AC outlet 11 of the lightning protection device 10, the protrusion 17 of the lightning protection device 10 may be arranged / configured to push the switch (SW) 23 of the HGW device 20. .

[Alternative example]
As an alternative example of the HGW apparatus 20, a modem (MODEM: Modulator-DEModulator), an ADSL modem (ADSL modem), an access point (access point), a network switch (network switch), a router (router), a proxy (proxy), a gateway (proxy) gateway, firewall, load balancer, bandwidth control device / security monitoring control device (gatekeeper), PC (personal computer), appliance, print server, digital tuner, digital recorder, Information home appliances, OA (Office Automation) devices and the like are conceivable.

  As an alternative example of the CPU 24, a network processor (NP), a microprocessor, a microcontroller, or a semiconductor integrated circuit (IC: Integrated Circuit) having a dedicated function can be considered. That is, the CPU 24 may be any processing device.

  As an alternative example of the alarm lamp 25, the speaker 26, and the network adapter 27, a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display), an organic EL display (Organic electroluminescence display), or a printer that prints output contents on paper or the like Examples of using a printing device such as a projector, a projection device such as a projector that projects output contents on a wall or screen, or an interface (I / F) for outputting information to an external display device or storage device Is also possible. That is, the alarm lamp 25, the speaker 26, and the network adapter 27 may be any output device.

  However, actually, it is not limited to these examples.

[Detection of connection with lightning protection device by HGW device]
First, a situation in which it is detected whether the HGW device is connected to the lightning protection device will be described.

  In order to connect the HGW device 20 and the lightning protection device 10, the modular plug 16 is connected to the modular connector 21.

  At this time, along with the connection between the modular plug 16 and the modular connector 21, the protrusion 17 of the lightning protection device 10 pushes in (presses down) the switch (SW) 23 of the HGW device 20, and is in an ON state. To. When the switch (SW) 23 of the HGW apparatus 20 is turned on, the detection signal 231 input from the switch (SW) 23 to the CPU 24 is changed. For example, it is assumed that the detection signal 231 that is normally at a high level (High) changes to a low level (Low) by turning on the switch (SW) 23.

  The CPU 24 detects a change in the detection signal 231 to determine whether the switch (SW) 23 is in an on (ON) state or an off (OFF) state, and whether or not the lightning protection device 10 is connected. to decide. For example, if the potential of the detection signal 231 is high (High), the CPU 24 determines that the lightning protection device 10 is not connected with the switch (SW) 23 turned off. On the other hand, if the potential of the detection signal 231 is low level (Low), it is determined that the lightning protection device 10 is connected while the switch (SW) 23 is on.

  Of course, the high level (High) and the low level (Low) may be reversed.

  When the CPU 24 determines from the detection signal 231 that the switch (SW) 23 is OFF and the lightning protection device 10 is not connected, the alarm lamp 25 is lit constantly / periodically / for a certain period of time. A warning that the lightning protection device 10 is not connected is notified to the user by blinking, voice guidance by the speaker 26, a beep sound, or the like.

  Furthermore, the CPU 24 may notify the connection state of the lightning protection device 10 to the base station or the server via the public line network using the network adapter 27.

[CPU supplement]
Although not essential, if the CPU 24 determines that the lightning protection device 10 is not connected when the switch (SW) 23 is OFF (OFF) based on the detection signal 231, the CPU 24 stops the HGW device 20 or sets the standby state. / You may be in a dormant state. At this time, if the CPU 24 determines that the lightning protection device 10 is connected when the switch (SW) 23 is on (ON) based on the detection signal 231, the CPU 24 activates the HGW device 20 or enters standby / hibernation. Let me recover.

  Alternatively, when the CPU 24 determines from the detection signal 231 that the lightning protection device 10 is connected with the switch (SW) 23 being on (ON), the power line of the AC plug 22 is short-circuited. The power supply to the inside of the HGW apparatus 20 is started.

[Switch (SW) 15 ON / OFF switching]
Next, when the power line between the lightning protection device and the HGW device is not correctly connected, the communication line is opened (open), and the power line between the lightning protection device and the HGW device is correctly connected. In the case of a failure, the situation where the communication line is brought into a short (short circuit) state will be described.

  Here, the relationship between the AC outlet 11 and the switch (SW) 15 will be described with reference to FIGS. 5 and 6.

[Switch (SW) 15 is off (OFF)]
FIG. 5 shows a normal state in which the AC plug 22 is not inserted into the AC outlet 11.

  The figure shown in the upper part of FIG. 5 is an image view of the appearance of the AC outlet 11, and the figure shown in the lower part of FIG. 5 is an image view of the cross section of the AC outlet 11.

  Normally, the AC outlet 11 is hidden under the slide cover 111. The slide cover 111 is a cover (outlet cover) that covers two poles (two electrodes) of the AC outlet 11.

  The slide cover 111 is provided with a protrusion 112 for pushing (pressing) the switch (SW) 15 to turn on the switch (SW) 15. At normal times, the protrusion 112 does not reach the switch (SW) 15, and therefore the switch (SW) 15 is in an OFF state.

[Switch (SW) 15 is on (ON)]
FIG. 6 shows a state when the AC plug 22 is inserted into the AC outlet 11.

  6, similarly to FIG. 5, the figure shown in the upper part of FIG. 6 is an image view of the appearance of the AC outlet 11, and the figure shown in the lower part of FIG.

  First, in order to insert the AC plug 22, the AC plug 22 is lightly inserted into a two-pole hole formed in the slide cover 111. Specifically, the AC plug 22 is inserted so as not to exceed the depth of the hole for the two poles (to the extent that it does not contact the main body of the lightning protection device 10).

  When the AC plug 22 and the slide cover 111 are slid while the AC plug 22 is lightly inserted into the two-pole hole opened in the slide cover 111, the two-pole hole opened in the slide cover 111 Since the positions of the AC outlet 11 and the two poles coincide with each other, the AC plug 22 can be inserted into the AC outlet 11.

  At this time, the projection 112 also slides in conjunction with the slide cover 111 and pushes in the switch (SW) 15, so that the switch (SW) 15 is turned on.

  As described above, when the AC plug 11 is not connected to the AC outlet 11 by configuring the switch (SW) 15 in the on (ON) / off (OFF) state in conjunction with the slide cover 111. The communication line is in an open (open) state.

  Actually, the slide cover 111 is manually slid to turn on the switch (SW) 15, and the two-pole hole opened in the slide cover 111 and the two poles of the AC outlet 11 are connected. When the positions match, the AC plug 22 is inserted deeply into the two-pole hole formed in the slide cover 111, and the AC plug 22 is inserted into the two poles of the AC outlet 11. The position may be fixed.

[Slide cover supplement]
Although it is not essential, the projection 17 is stored inside the casing of the lightning protection device 10 in a normal state, and when the projection 112 slides in conjunction with the slide cover 111, the projection 17 also slides in conjunction with the slide cover 111. Then, the lightning protection device 10 may be exposed outside the housing.

  In addition, when the AC plug 22 is removed from the two-pole hole formed in the slide cover 111, the slide cover 111 is automatically slid by an elastic member such as a spring or a power mechanism such as a small motor. You may make it return to a position (state shown in FIG. 5).

  5 and 6, the mechanism for pushing the switch (SW) 15 by sliding the slide cover 111 has been described. However, in actuality, the switch (SW) 15 is not limited to the slide, but is moved / operated by the slide cover 111. Any mechanism may be used as long as it has a structure that turns on / off.

  For example, by rotating the slide cover 111, the AC plug 22 can be inserted, and at the same time, the switch (SW) 15 is turned on (ON), or the slide cover 111 is removed to switch (SW) 15 A method of turning on the switch (SW) 15 when the slide cover 111 is deformed may be considered.

  Further, the switch (SW) 15 may not be a push-in switch as long as the communication line is in a function of opening (opening) / shorting (short-circuiting).

  For example, the switch (SW) 15 may be a switch of a type in which the conductor comes into contact with the slide of the slide cover 111.

  The switch (SW) 15 may be not only a mechanical switch but also a logic circuit that controls an analog switch IC.

  The switch (SW) 15 may be a type of switch that is turned on when the movement / operation of the slide cover 111 is detected. For example, the switch (SW) 15 is a type that is turned on when a signal indicating movement / operation of the slide cover 111 is received from a sensor or the like that detects movement / operation of the slide cover 111. The switch may be used.

[Wiring status]
Based on the functions described above, operations in each of the wiring states (1) to (5) described in the background art will be described.

  First, as the state (1), the operation in a state where the lightning protection device 10 is not connected to the HGW device 20 will be described.

  First, when the CPU 24 determines that the lightning protection device 10 is not connected when the switch (SW) 23 is OFF (OFF) based on the detection signal 231, the alarm lamp 25 is constantly / periodically / constant for a certain period of time. A warning that the lightning protection device 10 is not connected is notified to the user by lighting, blinking, voice guidance by the speaker 26, a beep sound, or the like.

  Furthermore, the CPU 24 can notify the connection state of the lightning protection device 10 to the base station or the server via the public line network using the network adapter 27.

  Next, as the states (2) and (3), the operation of the lightning protection device 10 is correctly connected to the HGW device 20, but the AC plug 12 of the lightning protection device 10 is not connected to the AC outlet. explain.

  Here, the correctly connected state refers to a state in which the switch (SW) 23 is pushed in by the protrusion 17 and turned on at the same time when the modular plug 16 is connected to the modular connector 21.

  In the state of (2), even if the AC plug 22 is correctly connected to the AC outlet 11, the AC plug 12 is not connected to the AC outlet, so that no power is supplied to the HGW device 20 so that it does not operate (start up). . Therefore, the user can realize that there is a problem with the connection.

  In the state (3), the AC plug 22 is connected to another AC outlet, and the HGW device 20 can be supplied with power, so that the operation can be started. However, since the AC plug 22 of the HGW device 20 is not connected to the AC outlet 11 of the lightning protection device 10, the protrusion 112 interlocked with the slide cover 111 of the AC outlet 11 does not slide and does not push the switch (SW) 15. Therefore, the switch (SW) 15 is not turned on (ON), but remains in the off (OFF) state. That is, in a state where the AC plug 22 is not connected to the AC outlet 11, the communication line is open (opened) and is disconnected. Thus, the user can notice that there is a problem with the connection.

  Finally, as the states (4) and (5), the operation when the lightning protection device 10 is correctly connected to the HGW device 20 and the AC plug 12 is also connected to the AC outlet will be described.

  In the state (4), similarly to the state (3), the AC plug 22 is connected to another AC outlet, and the HGW device 20 can receive power supply, so that the operation can be started. . However, since the AC plug 22 of the HGW device 20 is not connected to the AC outlet 11 of the lightning protection device 10, the protrusion 112 interlocked with the slide cover 111 of the AC outlet 11 does not slide and does not push the switch (SW) 15. Therefore, the switch (SW) 15 is not turned on (ON), but remains in the off (OFF) state. That is, in a state where the AC plug 22 is not connected to the AC outlet 11, the communication line is open (opened) and is disconnected. Thus, the user can notice that there is a problem with the connection.

  In the state (5), there is no problem because the connection is correct. The switch (SW) 15 is turned on (ON), and communication by the multi-function communication terminal is also possible.

[Effects of this embodiment]
In this embodiment, since the lightning protection device and the analog port of the HGW device are definitely connected, it is expected that the HGW device will be damaged due to a lightning surge due to inadequate user connection.

  Further, the connection state can be monitored on the base station side, which contributes to improvement of customer service.

Second Embodiment
The second embodiment of the present invention will be described below.

  In the first embodiment of the present invention, as shown in FIG. 3, the HGW device 20 uses the protrusion 17 of the lightning protection device 10 and the switch (SW) 23 of the HGW device 20 to connect the lightning protection device 10. However, it is also possible to prepare a dedicated interface instead.

  In the second embodiment of the present invention, the connection state of the lightning protection device 10 is changed to the signal plug 18 of the lightning protection device 10 as shown in FIG. 7 instead of the protrusion 17 and the switch (SW) 23 of the HGW device 20. When connected to the signal connector 28 of the HGW device 20, the connection state of the lightning protection device 10 is detected.

[System configuration example]
As shown in FIG. 7, the lightning protection connection method according to the second embodiment of the present invention includes a lightning protection device 10 and an HGW device 20.

  The signal plug 18 is connected to the signal connector 28 by a signal cable.

  The signal connector 28 outputs a detection signal 281 whose potential state changes according to the connection of the signal plug 18.

  For example, it is assumed that the detection signal 281 that is normally at a low level (Low) changes to a high level (High) by connecting the signal plug 18 of the lightning protection device 10 to the signal connector 28 of the HGW device 20.

  Here, it is assumed that the signal plug 18 inputs a high-level (High) detection signal 281 to the signal connector 28 via the signal cable.

  The CPU 24 detects a change in the detection signal 281 and determines whether or not the lightning protection device 10 is connected. For example, if the potential of the detection signal 281 is low level (Low), the CPU 24 determines that the lightning protection device 10 is not connected. If the potential of the detection signal 281 is high level (High), the lightning protection device 10 is determined to be connected.

  Of course, the high level (High) and the low level (Low) may be reversed.

  The signal plug 18 uses a communication method in the signal connector 28 by using a communication system such as I2C (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), or UART (Universal Asynchronous Receiver Transmitter). You may enter. Although not shown, in this case, the lightning protection device 10 includes a detection circuit for detecting that the HGW device 20 is connected by the above communication method, a CPU that supports the above communication method, and the like. A processor is provided.

  Further, the CPU 24 determines that the lightning protection device 10 is connected when predetermined data is input as the detection signal 281 from the signal plug 18 to the signal connector 28, not limited to the potential change of the detection signal 281. You may make it do.

[Detection signal supplement]

  When a telephone line is used, a telephone line modular cable is used as a communication line between the modular plug 16 and the modular connector 21. Usually, a 6-pole 2-core cable is used as a modular cable for a telephone line.

  Here, as a communication line between the modular plug 16 and the modular connector 21, a 6-pole 4-core cable or a 6-pole 6-core cable is used to detect a free pin other than the pin used in the telephone line. By assigning the signal 281, the modular plug 16 and the modular connector 21 can be used as a substitute for the signal plug 18 and the signal connector 28.

[Effects of this embodiment]
In this embodiment, even when the AC plug 22 that has been a problem in the wiring states (3) and (4) is connected to an AC outlet other than the AC outlet 11, the CPU 24 Alarm notification to the user (alarm lamp, voice, etc.) and notification to the base station or server side are possible.

However, it is also possible to use a short-range wireless communication system as its application.

  In the third embodiment of the present invention, the connection state of the lightning protection device 10 is changed to the RFID (Radio Frequency Identification) of the lightning protection device 10 as shown in FIG. 8 instead of the protrusion 17 and the switch (SW) 23 of the HGW device 20. ) When the tag 19 approaches / contacts the RFID reader 29 of the HGW device 20, the connection state of the lightning protection device 10 is detected.

[System configuration example]
As shown in FIG. 8, the lightning protection connection method according to the third embodiment of the present invention includes a lightning protection device 10 and an HGW device 20.

  The lightning protection device 10 is connected to the HGW device 20 in a connection form as shown in FIG.

[Configuration example of lightning protection device]
The lightning protection device 10 includes an AC outlet 11, an AC plug 12, a modular connector 14, a switch (SW) 15, a modular plug 16, and an RFID tag 19.

[Configuration example of HGW device]
The HGW apparatus 20 includes a modular connector 21, an AC plug 22, a CPU 24, an alarm lamp 25, a speaker 26, a network adapter 27, and an RFID reader 29.

  The above-described AC outlet 11, AC plug 12, modular connector 14, switch (SW) 15, modular plug 16, modular connector 21, AC plug 22, CPU 24, alarm lamp 25, speaker 26, and network adapter 27 are fundamental. Further, this is the same as the first embodiment (shown in FIG. 3).

  The RFID tag 19 is a wireless IC chip. Regardless of contact type / non-contact type. Moreover, a passive tag / active tag is not ask | required. The RFID tag 19 is read from the RFID reader 29 by short-range wireless communication. The RFID tag is used for various purposes, and an RFID tag attached to the lightning protection device 10 for another use, such as an RFID tag for product management, can be used as the RFID tag 19 in the present embodiment.

  Here, it is assumed that the RFID reader 29 outputs a detection signal 291 when the RFID tag 19 is read by short-range wireless communication.

  The CPU 24 detects a change in the detection signal 291 and determines whether or not the lightning protection device 10 is connected. For example, if the potential of the detection signal 291 is low (Low), the CPU 24 determines that the lightning protection device 10 is not connected, and if the potential of the detection signal 291 is high (High), the lightning protection device 10 is determined to be connected.

<Fourth embodiment>
The fourth embodiment of the present invention will be described below.

  In the first embodiment of the present invention, as shown in FIGS. 5 and 6, when the AC plug 22 of the HGW device 20 is correctly connected to the AC outlet 11 of the lightning protection device 10, the AC plug 22 is connected to the AC outlet. 11, the projection 112 is also slid in conjunction with the slide cover 111, the switch (SW) 15 is pushed in, and the switch (SW) 15 is turned on. Similarly, it is also possible to provide a slide cover on the modular connector 21 of the HGW device 20 so that the switch (SW) 23 is turned on.

  In the fourth embodiment of the present invention, as shown in FIGS. 9 and 10, when the modular plug 16 of the lightning protection device 10 is correctly connected to the modular connector 21 of the HGW device 20, the modular plug 16 is connected to the modular connector. The slide cover 211 is slid, the projection 212 is also slid in conjunction with the slide cover 211, and the switch (SW) 23 is pushed in to turn on the switch (SW) 23.

  In this case, the protrusion 17 of the lightning protection device 10 is not necessary. In other words, the protrusion 212 corresponds to the protrusion 17 of the lightning protection device 10.

[Switch (SW) 23 ON / OFF switching]
If the communication line between the lightning protection device and the HGW device is not properly connected, the signal line for the detection signal is set to open (open), and the communication line between the lightning protection device and the HGW device is correct. A description will be given of a situation where the signal line of the detection signal is short-circuited when connected.

  Here, the relationship between the modular connector 21 and the switch (SW) 23 will be described with reference to FIGS. 9 and 10.

[Switch (SW) 23 is OFF]
FIG. 9 shows a normal state where the modular plug 16 is not inserted into the modular connector 21.

  9 is an image view of the external appearance of the modular connector 21, and the view shown in the lower stage of FIG. 9 is an image view of a cross section of the modular connector 21.

  Normally, the modular connector 21 is hidden under the slide cover 211. The slide cover 211 is a cover (connector cover) that covers the analog port of the modular connector 21.

  The slide cover 211 is provided with a protrusion 212 for pushing (pressing) the switch (SW) 23 to turn on the switch (SW) 23. Normally, the protrusion 212 does not reach the switch (SW) 23, so the switch (SW) 23 is in an off state.

[Switch (SW) 23 is on (ON)]
FIG. 10 shows a state when the modular plug 16 is inserted into the modular connector 21.

  10, similarly to FIG. 9, the figure shown in the upper part of FIG. 10 is an image view of the appearance of the modular connector 21, and the figure shown in the lower part of FIG. 10 is an image view of the cross section of the modular connector 21.

  First, in order to insert the modular plug 16, the modular plug 16 is lightly inserted into the analog port hole formed in the slide cover 211. Specifically, the modular plug 16 is inserted so as not to exceed the depth of the analog port hole (not to contact the lightning protection device 10 main body).

  When the modular plug 16 and the slide cover 211 are slid while the modular plug 16 is lightly inserted into the analog port hole formed in the slide cover 211, the analog port hole of the modular connector 21 and the modular connector 21 are provided. Therefore, the modular plug 16 can be inserted into the modular connector 21.

  At this time, the projection 212 also slides in conjunction with the slide cover 211 and pushes in the switch (SW) 23, so that the switch (SW) 23 is turned on.

  As described above, by configuring the switch (SW) 23 in the on (ON) / off (OFF) state in conjunction with the slide cover 211, the modular connector 21 is not connected to the AC plug. The communication line is in an open (open) state.

  Actually, the slide cover 211 is manually slid to turn on the switch (SW) 23, and the analog port hole formed in the slide cover 211 and the analog port of the modular connector 21 are connected. When the positions match, the modular plug 16 is inserted deeply into the analog port hole formed in the slide cover 211, and the modular plug 16 is inserted into the analog port of the modular connector 21. The position may be fixed.

[Slide cover supplement]
Although not essential, when the modular plug 16 is removed from the analog port hole formed in the slide cover 211, the slide cover 211 is automatically slid by an elastic member such as a spring or a power mechanism such as a small motor. The original position (the state shown in FIG. 9) may be returned.

  9 and 10, the mechanism for pushing the switch (SW) 23 by sliding the slide cover 211 has been described. However, in practice, the switch (SW) 23 is not limited to the slide but is moved / operated by the slide cover 211. Any mechanism may be used as long as it has a structure that turns on / off.

  For example, by rotating the slide cover 211, the modular plug 16 can be inserted, and at the same time, the switch (SW) 23 is turned on, or the slide cover 211 is removed to remove the switch (SW) 23. A method of turning on the switch (SW) 23 when the slide cover 211 is deformed may be considered.

  Further, the switch (SW) 23 may not be a push-type switch as long as the communication line is in a function of opening (opening) / shorting (short-circuiting).

  For example, the switch (SW) 23 may be a switch of a type in which the conductor comes into contact with the slide cover 211 by sliding.

  The switch (SW) 23 may be not only a mechanical switch but also a logic circuit that controls an analog switch IC.

  The switch (SW) 23 may be a type of switch that is turned on when the movement / operation of the slide cover 211 is detected. For example, the switch (SW) 23 is a type that is turned on when a signal indicating the movement / operation of the slide cover 211 is received from a sensor or the like that detects the movement / operation of the slide cover 211. The switch may be used.

<Fifth Embodiment>

However, instead of the detection signal 231, it may be configured to receive power (receive power).

  In the fifth embodiment of the present invention, as shown in FIG. 11, the switch (SW) 23 of the HGW device 20 is connected to the AC plug 22, and the protrusion 17 of the lightning protection device 10 is connected to the switch (SW) 23 of the HGW device 20. When the switch is turned on, the switch (SW) 23 connects the AC plug 22 and the CPU 24 to supply power to the CPU 24.

Alternatively, the AC-DC conversion circuit may include a switch (SW) 23.

  In the present embodiment, the CPU 24 cannot receive power (receive power) when the lightning protection device 10 is not connected and the switch (SW) 23 is in an off state (OFF). The warning that the lightning protection device 10 is not connected cannot be notified to the user by lighting, blinking, voice guidance by the speaker 26, a beep sound, or the like.

  However, since no power is supplied to the HGW device 20 and the HGW device 20 does not operate (start up), the user can notice that there is a connection problem. That is, it can be said that the CPU 24 notifies the user that the lightning protection device 10 is not connected because the HGW device 20 is not activated.

[Supplement of protrusion and switch (SW)]
Although not essential, the protrusion 17 of the lightning protection device 10 may also serve as the AC outlet 11, and the switch (SW) 23 of the HGW device 20 may also serve as the AC plug 22. In this case, the AC outlet 11 and the AC plug 22 are not necessary.
