Description

  The present invention relates to a functional device used in a wiring system capable of transmitting information and power and an extended functional module used in the functional device.

  Conventionally, in a system that performs load operation (monitoring) control through a terminal device, a transmission signal composed of a multipolar baseband signal is sent from the central monitoring device to the terminal device by time division multiplexing, and each terminal device transmits this transmission signal. There has been a system for transmitting and receiving information and obtaining a power source for a terminal circuit unit (see, for example, Patent Document 1).

In this system, a switch box standardized for an embedded wiring device and an operation terminal provided with an operation switch or the like using a mounting frame corresponding to the switch box are embedded in a wall surface and wired. It is designed to be used in the same way as a wall switch. When installing two sets of operation terminals, use a double mounting frame with two mounting windows, attach a series of one side of the mounting frame to a series of switch boxes, and attach the other side to the wall. It has been arranged so that the two operation terminals are provided side by side by arranging the operation terminals on the respective mounting windows. In addition, by bringing the conductive pieces provided between the mounting windows into contact with the lead pieces of the operating terminal provided on the mounting windows on both sides, from one operating terminal (switch box side) to the other operating terminal. The signal line is sent and wired.
Japanese Patent No. 3136006

  By the way, although power can be supplied to the terminal circuit unit of the terminal by the transmission signal in the above-described system, for example, power supply to the load controlled by the control terminal due to limitation of the current capacity of the signal line, etc. It was configured to be supplied from the commercial law power supply at the installation location. Therefore, it is only necessary to connect two signal lines between the terminals, and the wiring for the signal lines can be reduced. On the other hand, since the wiring of the power supply line to the load remains as before, the control terminal There was a problem that the installation location of the department was restricted.

  Moreover, since the terminal only has a function of taking in data from the monitoring target or controlling the load based on the control data, the terminal itself is not a configuration having an original function, and cannot expand various functions. It was.

  Furthermore, if various functions are to be developed, it is necessary to simultaneously operate a plurality of functions with the power supply capability supplied by the gate device, and it may be necessary to supply power efficiently.

  The present invention has been made in view of the above-described points, and it is possible to construct a system having a wide variety of functions only by connecting to a gate device, and without increasing the power supply capability of the gate device. It is an object of the present invention to provide a functional device capable of efficiently supplying power and an extended function module used therefor so that the functions can be operated without excess or deficiency.

The functional device according to the present invention is a functional device connected to a gate device having a connection port formed by modularizing a power path connection port connected to a power line and an information path connection port connected to an information line. A basic function module that is connected to the power path connection port and the information path connection port of the gate device, obtains the power from the gate device, and exchanges the information signal through the gate device; and a basic function An extension function module configured to be connectable to the module and capable of receiving power from the basic function module in a non-contact manner. The extension module is a high power consumption extension function module that requires more than a predetermined power consumption and less than the predetermined power. power provided with one at least one low-power extensions modules requiring the basic functional modules, a rectangular cross section The power supply portion having a fitting recess is formed, and the high power consumption extension function module and the low power consumption extension function module are a power supply portion in which a fitting recess having a rectangular section is formed and a fitting projection having a rectangular section. Each of the power receiving portions is formed with an opening, and the opening surface of the fitting concave portion of the basic function module and the protruding cross section of the fitting convex portion of the high power consumption extended function module have substantially the same width and length. The opening surface of the fitting recess of the high power consumption extension function module and the low power consumption extension function module and the protruding cross section of the fitting protrusion of the low power consumption extension function module have substantially the same width and length. In addition, the opening surface of the fitting concave portion of the basic function module should have either the same width or length and the other one longer than the protruding cross section of the fitting convex portion of the low power consumption extended function module. Special It is an.

  The functional device having the above configuration is connected to a gate device having a connection port formed by modularizing a power path connection port connected to the power line and an information path connection port connected to the information line. The basic function module is connected to the power path connection port and the information path connection port of the gate device, obtains power from the gate device, and transmits and receives information signals through the gate device. Furthermore, the extended function module is a module for adding various functions, and operates by receiving power from the basic function module in a non-contact manner. The extension function module is classified into a high power consumption extension function module that requires power consumption equal to or higher than a predetermined power and a low power consumption extension function module that requires power consumption less than a predetermined power.

  Here, in the functional device used in such a wiring system, an extended function module for adding various functions to the basic function module can be attached, and further an extended function module can be attached to the extended function module. When the extended function modules are sequentially connected in this way, power supply to each extended function module is performed by a non-contact power supply mechanism included in each module. For example, when three extended function modules are connected to the basic function module, if the power supply efficiency of the non-contact power supply mechanism when performing non-contact power supply is 70%, the third extended function module includes the basic function module. Only 34% (100% (basic function module) → 70% (first) → 49% (second) → 34% (third)) of power supplied to the power supply can be supplied. Therefore, if an extended function module with high power consumption is connected to a point where a plurality of extended function modules are sandwiched from the basic function module, there is a possibility that the extended function module may not function or malfunction due to insufficient power supply capability. In addition, the power supply capability of the gate device of the wiring system is limited, and there is a demand for energy saving. Therefore, it is necessary to use it effectively within a predetermined power range.

  In the above configuration, when a further function expansion module is fitted to the function expansion module, the secondary side is the low power consumption expansion function module, and the primary side is the high power consumption expansion function module and the low power consumption expansion function module. However, when the secondary side is a high power consumption extension function module, the primary side cannot be fitted to either the high power consumption extension function module or the low power consumption extension function module. That is, when the high power consumption module is already fitted on the primary side, only the low power consumption extension function module can be connected thereafter.

  Therefore, high power consumption expansion function modules with high power consumption can be connected only to basic function modules with a large amount of power supply, enabling efficient power supply to each function module without increasing the power supply capability of the gate device. In addition to being able to be supplied, it is possible to prevent the extended function module from being in a state where it does not function due to a mistake in the mounting order by the user.

Specifically , the basic function module includes a power supply unit in which a fitting recess having a rectangular cross section is formed, and the high power consumption extension function module and the low power consumption extension function module include a fitting recess having a rectangular cross section.

A fitting recess having a rectangular cross section is formed in the supply portion. The opening surface of the fitting concave portion of the basic function module and the protruding cross section of the fitting convex portion of the high power consumption extended function module have substantially the same width and substantially the same length as can be fitted, and have high consumption. The opening surface of the fitting recess of the power extension function module and the low power consumption extension function module and the protruding cross section of the fitting protrusion of the low power consumption extension function module are approximately the same width and length as long as they can be fitted. However, the opening surface of the fitting recess of the basic function module has either the same width or length as the protruding cross section of the fitting protrusion of the low power consumption extended function module. The other is configured to be longer.

  Accordingly, the protruding cross section of the fitting convex portion of the high power consumption extension function module having substantially the same width and substantially the same length as the opening surface of the fitting concave portion of the basic function module is the fitting convex portion of the low power consumption extension function module. High power consumption expansion because either the width or the length is longer than the opening surface of the mating recess of the high power consumption expansion function module and the low power consumption expansion function module having substantially the same width and length as the protruding cross section of The secondary side of the high power consumption extension function module cannot be fitted to the primary side of the function module or the low power consumption extension function module.

Each of the power receiving portions is formed, and the opening depth of the fitting concave portion of the basic function module and the protruding length of the fitting convex portion of the high power consumption extension function module have substantially the same length and high power consumption. The opening depth of the fitting recess of the extension function module and the low power consumption extension function module and the protrusion length of the fitting protrusion of the low power consumption extension function module have substantially the same length, and the fitting recess of the basic function module The opening depth is configured to be longer than the protruding length of the fitting convex portion of the low power consumption extension function module.

  In this case, the basic function module has a fitting recess formed in the power supply unit, and each extended function module has a fitting projection formed in the power receiving unit and a fitting recess formed in the power supply unit. Is done. The opening depth of the fitting concave portion of the basic function module and the protrusion length of the fitting convex portion of the high power consumption extension function module have substantially the same length, and the high power consumption extension function module and the low power consumption extension function. The opening depth of the fitting recess of the module and the protrusion length of the fitting protrusion of the low power consumption expansion function module have substantially the same length, and the opening depth of the fitting recess of the basic function module is low power consumption. It is configured to be longer than the protruding length of the fitting convex portion of the extended function module.

  Therefore, the protrusion length of the fitting protrusion of the high power consumption extension function module having the same length as the opening depth of the fitting recess of the basic function module is the protrusion length of the fitting protrusion of the low power consumption extension function module. Is longer than the opening depth of the mating recess of the high power consumption extension function module and low power consumption extension function module having approximately the same length as that of the power consumption extension function module or the low power consumption extension function module. The secondary side of the power extension function module cannot be fitted (the primary side and secondary side functional modules are not joined even if the fitting convex part is inserted into the fitting concave part for fitting, and they are fitted. Can't).

  Alternatively, the basic function module includes a power supply unit formed with a fitting convex portion having a rectangular cross section, and the high power consumption expansion function module and the low power consumption expansion function module are formed with a fitting convex portion having a rectangular cross section. And a power receiving portion formed with a fitting recess having a rectangular cross section, and a projecting cross section of the fitting convex portion of the basic function module and an opening surface of the fitting concave portion of the high power consumption extension function module.

  In this case, the basic function module is formed with a fitting convex portion having a rectangular cross section in the power supply unit, and the high power consumption extension function module and the low power consumption extension function module have a rectangular cross section in the power receiving unit. A mating recess is formed, and a fitting projection having a rectangular cross section is formed in the power supply unit. The protruding cross section of the fitting convex part of the basic function module and the opening surface of the fitting concave part of the high power consumption extension function module have substantially the same width and substantially the same length, and the high power consumption extension function module and low power consumption. The protruding section of the fitting convex part of the extended function module and the opening surface of the fitting concave part of the low power consumption extended function module have substantially the same width and substantially the same length, and the protruding convex part of the basic function module protrudes. The cross section is configured such that either the width or the length is substantially the same and the other is shorter than the opening surface of the fitting recess of the low power consumption extension function module.

  Therefore, the opening surface of the fitting recess of the high power consumption extension function module having substantially the same width and substantially the same length as the protruding section of the fitting projection of the basic function module is the same as the fitting recess of the low power consumption extension function module. High power consumption expansion because either the width or length is shorter than the protruding cross section of the mating protrusion of the high power consumption expansion function module and low power consumption expansion function module that have approximately the same width and length as the opening surface. The secondary side of the high power consumption extension function module cannot be fitted to the primary side of the function module or the low power consumption extension function module.

  Alternatively, the basic function module includes a power supply unit in which a fitting protrusion is formed, and the high power consumption extension function module and the low power consumption extension function module include a power supply unit and a fitting in which a fitting protrusion is formed. Each power receiving part is provided with a recessed part, and the protrusion length of the fitting convex part of the basic function module and the opening depth of the fitting concave part of the high power consumption extension function module have substantially the same length, and high power consumption. The protrusion length of the fitting protrusion of the power extension function module and the low power consumption extension function module and the opening depth of the fitting recess of the low power consumption extension function module have substantially the same length, and the basic function module is fitted. The protruding length of the convex portion is configured to be shorter than the opening depth of the fitting concave portion of the low power consumption extension function module.

  In this case, the basic function module has a fitting convex portion formed in the power supply portion, and each extended function module has a fitting concave portion formed in the power receiving portion and a fitting convex portion in the power supply portion. It is formed. And the protrusion length of the fitting convex part of the basic function module and the opening depth of the fitting concave part of the high power consumption extension function module have substantially the same length, and the high power consumption extension function module and the low power consumption extension function The protrusion length of the fitting protrusion of the module and the opening depth of the fitting recess of the low power consumption expansion function module have substantially the same length, and the protrusion length of the fitting protrusion of the basic function module is low. It is configured to be shorter than the opening depth of the fitting recess of the power expansion function module.

Higher power consumption on the primary side of the high power consumption expansion function module or the low power consumption expansion function module because it is shorter than the protruding length of the fitting convex part of the high power consumption expansion function module and the low power consumption expansion function module having substantially the same length. The secondary side of the power expansion function module cannot be fitted (the primary and secondary functional modules are not joined as a whole even if the fitting convex part is inserted into the fitting concave part for fitting, and the fitting is not performed. Cannot be matched).

  As described above, by making a part of the shape of the fitting concave portion and the fitting convex portion different from each other, it is possible to easily form a fitting / non-fitting configuration.

  In the functional device used in the wiring system of the present invention, as described above, the extended function module 9 for adding various functions is attached to the basic function module 8, and the extended function module 9 has a further extended function module 9. Can be attached. Thus, when the extended function modules 9 are connected in order, power supply to each extended function module 9 is performed by a non-contact power supply mechanism included in each module. In the wiring system of the present embodiment, if the thickness of the housing of each module is defined as 2 to 3 mm, the power supply efficiency when performing non-contact power supply is limited to about 70%. That is, about 30% is attenuated each time non-contact power is supplied to the adjacent functional module. For example, when three extended function modules 9 are connected to the basic function module 8 and the power supply efficiency of each non-contact power supply mechanism is 70%, the third extended function module 9 includes the basic function module 8. Only 34% (100% (basic function module 9)-> 70% (first)-> 49% (second)-> 34% (third)) of power can be supplied. Accordingly, if the extended function module 9 having high power consumption is connected to the basic function module 8 between the extended function modules 9, the power supply capability is insufficient and the extended function module 9 may not function or may malfunction. Can occur. In addition, there is a limit to the power supply capability of the gate device 3 of the wiring system, and there is also a demand for energy saving, so it is necessary to use it effectively within a predetermined power range to be supplied.

  In the above configuration, when the additional function expansion module 9 is fitted to the expansion function module 9, when the secondary side is the low power consumption expansion module 9L, the primary side is the high power consumption expansion function module 9H and the low power consumption expansion function. It can be fitted to any of the modules 9L, but when the secondary side is the high power consumption extension function module 9H, the primary side is either the high power consumption extension function module 9H or the low power consumption extension function module 9L. Can not be fitted. That is, when the high power consumption module 9H is already fitted on the primary side, only the low power consumption extension function module 9L can be connected thereafter.

  Therefore, as shown in FIG. 1 and FIGS. 5 to 8, the high power consumption extension function module 9 </ b> H that consumes a large amount of power can be connected only to the basic function module 8 with a large amount of power supply. It is possible to efficiently supply power to each functional module without increasing the capability, and it is possible to prevent the extended functional module 9 from being in a non-functional state due to an incorrect installation order by the user.

  As a more specific example, each aspect of FIG. 1 and FIGS.

  In the fitting mode in FIG. 1, the basic function module 8 is formed with a fitting recess 8 a having a rectangular cross section in the power supply part (that is, on the connection surface with the secondary side casing near the primary side core). The high power consumption extension function module 9H and the low power consumption extension function module 9L include a fitting projection having a rectangular cross section on the power receiving unit (that is, on the connection surface with the primary side casing near the secondary side core). The portions 9Hb and 9Lb are formed, and fitting recesses 9Ha and 9La having a rectangular cross section are formed in the power supply portion.

  The opening surface (8ax × 8ay) of the fitting concave portion 8a of the basic function module 8 and the protruding cross section (9Hbx × 9Hby) of the fitting convex portion 9Hb of the high power consumption extended function module 9H are substantially the same width (8ax = 9Hbx) and substantially the same length (8ay = 9Hby), and opening surfaces of the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L (9Hax × 9Hay, 9Lax × 9Ray) And the protrusion cross section (9Lbx × 9Lby) of the fitting convex portion 9Lb of the low power consumption extension function module 9L has substantially the same width (9Hax = 9Lax = 9Lbyx) and substantially the same length (9Hay = 9Lay = 9Lby). However, the opening surface (8ax × 8ay) of the fitting recess 8a of the basic function module 8 is the fitting protrusion of the low power consumption extension function module 9L. Compared to Lb projected cross-section of (9Lbx × 9Lby), substantially longer length with the same width (8ax = 9Lbx) (8ay> 9Lby) as configured. Here, having substantially the same width or substantially the same length means having the same width or the same length to the extent that the fitting convex portion can be fitted into the fitting concave portion.

  Therefore, as shown in FIG. 1A, the fitting convex portions 9Hb and 9Lb of the high power consumption extension function module 9H or the low power consumption extension function module 9L can be fitted into the fitting recess 8a of the basic module 8. The fitting protrusion 9Lb of the low power consumption extension function module 9L can be fitted into the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the protruding cross section (9Hbx × 9Hby) of the fitting convex portion 9Hb of the high power consumption extended function module 9H having substantially the same width and substantially the same length as the opening surface (8ax × 8ay) of the fitting concave portion 8a of the basic function module 8 ) Is a high power consumption extension function module 9H and a low power consumption extension function module 9L having substantially the same width and length as the protruding cross section (9Lbx × 9Lby) of the fitting convex portion 9Lb of the low power consumption extension function module 9L. As shown in FIG. 1B, the length (the vertical length of the module) is longer than the opening surfaces (9Hax × 9Hay, 9Lax × 9Ray) of the fitting recesses 9Ha, 9La (9Hby> 9Hay, 9Lay). In addition, the high power consumption extension function module 9H or the low power consumption extension function module 9L has a high power consumption extension machine in the fitting recesses 9Ha and 9La (primary side). The fitting projection 9Hb (secondary side) of the function module 9H cannot be fitted.

  The fitting mode in FIG. 5 is the same as the fitting mode in FIG. 1 except that the opening surface (8ax × 8ay) of the fitting recess 8a of the basic function module 8 protrudes from the fitting projection 9Lb of the low power consumption extended function module 9L. Compared to the cross section (9Lbx × 9Lby), the width is substantially the same (8ay = 9Lby) and the width is longer (8ax> 9Lbx).

  Accordingly, as shown in FIG. 5A, the fitting convex portions 9Hb and 9Lb of the high power consumption extension function module 9H or the low power consumption extension function module 9L can be fitted into the fitting recess 8a of the basic module 8. The fitting protrusion 9Lb of the low power consumption extension function module 9L can be fitted into the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the protruding cross section (9Hbx × 9Hby) of the fitting protrusion 9Hb of the high power consumption extension function module 9H is the opening surface of the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L. Since the width (length in the thickness direction of the module) is longer than (9Hax × 9Hay, 9Lax × 9Ray) (9Hbx> 9Hax, 9Lax), as shown in FIG. 5B, the high power consumption extension function module 9H or low The fitting protrusion 9Hb (secondary side) of the high power consumption extension function module 9H cannot be fitted into the fitting recesses 9Ha, 9La (primary side) of the power consumption extension function module 9L.

  Next, in the fitting mode in FIG. 6, the basic function module 8 has a fitting recess 8a formed in the power supply unit, and the high power consumption extension function module 9H and the low power consumption extension function module 9L receive power. A fitting convex portion 9Hb is formed in the portion, and a fitting concave portion 9Ha is formed in the power supply portion. The opening depth 8ah of the fitting recess 8a of the basic function module 8 and the protrusion length 9Hbh of the fitting protrusion 9Hb of the high power consumption extension function module 9H have substantially the same length (9Ha = 9hbh). The opening depths 9Hah and 9Lah of the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L and the protrusion length 9Lbh of the fitting protrusion 9Lb of the low power consumption extension function module 9L Have substantially the same length (9Hah, 9Lah = 9Lbh), and the opening depth 8ah of the fitting recess 8a of the basic function module 8 is the protruding length of the fitting protrusion 9Lb of the low power consumption extension function module 9L. It is configured to be longer than 9Lbh. Here, having substantially the same length means that when the fitting convex portion is fitted into the fitting concave portion, the side end portions of the modules to be joined have the same length so that they can contact each other. .

  Therefore, as shown in FIG. 6A, the fitting convex portions 9Hb and 9Lb of the high power consumption extension function module 9H or the low power consumption extension function module 9L can be fitted into the fitting recess 8a of the basic module 8. The fitting protrusion 9Lb of the low power consumption extension function module 9L can be fitted into the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the protruding length 9Hbh of the fitting convex portion 9Hb of the high power consumption extension function module 9H having substantially the same length as the opening depth 8ah of the fitting recess 8a of the basic function module 8 is the low power consumption extension function module 9L. This is because the fitting recesses 9Ha, 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L having a length substantially the same as the protrusion length 9Lbh of the fitting protrusion 9Lb is longer than the opening depths 9Hah, 9Lah. The fitting protrusion 9Hb (secondary side) of the high power consumption extension function module 9H is fitted into the fitting recesses 9Ha and 9La (primary side) of the high power consumption extension function module 9H or the low power consumption extension function module 9L. (The joint surfaces of the primary and secondary functional modules are in contact with each other even if the fitting convex portion 9Hb is inserted into the fitting concave portions 9Ha and 9La to be fitted. Is not, it is impossible to fit).

  In addition, as long as the shape of a fitting convex part and a fitting recessed part is a shape which can mutually correspond (it can fit), various shapes, such as a rectangular parallelepiped (square bar shape), a cylindrical shape (round bar shape), and a cone shape, can be adopted. is there.

  Subsequently, the fitting mode in FIG. 7 is such that a fitting convex portion is formed on the secondary side and a fitting concave portion is formed on the primary side in the fitting mode of FIG. That is, the basic module 8 is formed with a fitting convex portion 8b having a rectangular cross section in the power supply portion, and the high power consumption extension function module 9H and the low power consumption extension function module 9L have a rectangular cross section in the power receiving portion. Fitting recesses 9Ha and 9La are formed, and fitting projections 9Hb and 9Lb having a rectangular cross section are formed in the power supply portion. The protruding cross section (8bx × 8by) of the fitting convex portion 8b of the basic function module 8 and the opening surface (9Hax × 9Hay) of the fitting concave portion 9Ha of the high power consumption extension function module 9H are substantially the same width (8bx = 9ax). And the protruding sections (9Hbx × 9Hby, 9Lbx × 9Lby) of the fitting convex portions 9Hb, 9Lb of the high power consumption extension function module 9H and the low power consumption extension function module 9L, which have substantially the same length (8by = 9ay). The opening surface (9 Lax × 9 Lay) of the fitting recess 9La of the low power consumption extension function module 9L has substantially the same width (9Hbx = 9Lbx = 9Lax) and substantially the same length (9Hby = 9Lby = 9Lay). The protruding cross section (8bx × 8by) of the fitting convex portion 8b of the functional module 8 has an opening surface (9 of the fitting concave portion 9La of the low power consumption extended functional module 9L). Compared with ax × 9Lay), substantially the length of the same width (8bx = 9Lax) is configured shorter (8by <9Lay).

  Therefore, as shown in FIG. 7 (a), the fitting recess 8Ha of the high power consumption extension module 9H or the low power consumption extension function module 9L can be fitted to the fitting protrusion 8b of the basic module 8. The fitting recess 9La of the low power consumption extension function module 9L can be fitted into the fitting protrusions 9Hb, 9Lb of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the opening surface (9Hax × 9Hay) of the fitting recess 9Ha of the high power consumption extension function module 9H having substantially the same width and length as the protruding cross section (8bx × 8by) of the fitting convex portion 8b of the basic function module 8 ) Of the high power consumption extension function module 9H and the low power consumption extension function module 9L having substantially the same width and the same length as the opening surface (9Lax × 9Ray) of the fitting recess 9La of the low power consumption extension function module 9L. As shown in FIG. 7B, the length (the length in the vertical direction of the module) is shorter than the protruding cross section (9Hbx × 9Hby, 9Lbx × 9Lby) of the fitting convex portions 9Hb, 9Lb (9Hay <9Hby, 9HLby). In addition, the high power consumption expansion function module 9H or the low power consumption expansion function module 9L has high power consumption expansion on the fitting protrusions 9Hb and 9Lb (primary side). The fitting recess 9Ha (secondary side) of the functional module 9H cannot be fitted.

  As in the relationship between FIG. 1 and FIG. 5 described above, the protruding section (8bx × 8by) of the fitting convex portion 8b of the basic function module 8 also has a low power consumption extension function module in the fitting mode of FIG. It is also possible to adopt an aspect in which the length is substantially the same (8by = 9Ray) and the width is shorter (8bx <9Lax) than the opening surface (9Lax × 9Ray) of the 9L fitting recess 9La. Here, illustration is omitted.

  Furthermore, as shown in FIG. 8, it is also possible to define the relationship between the protrusion length of the fitting convex portion and the opening depth of the fitting concave portion, as in FIG. In the fitting mode of FIG. 8, the basic function module 8 is formed with a fitting convex portion 8b in the power supply unit, and the high power consumption extended function module 9H and the low power consumption extended function module 9L are provided in the power receiving unit. The fitting recesses 9Ha and 9La are formed, and the fitting protrusions 9Hb and 9Lb are formed in the power supply unit. And the protrusion length 8bh of the fitting convex part 8b of the basic function module 8 and the opening depth 9Hah of the fitting concave part 9Ha of the high power consumption extension function module 9H have substantially the same length (8bh = 9Hah). The projecting lengths 9Hbh and 9Lbh of the fitting protrusions 9Hb and 9Lb of the high power consumption extension function module 9H and the low power consumption extension function module 9L and the opening depth 9Lah of the fitting recess 9La of the low power consumption extension function module 9L Have substantially the same length (9Hbh = 9Lbh = 9Lah), and the protrusion length 8bh of the fitting protrusion 8b of the basic function module 8 is the opening depth of the fitting recess 9La of the low power consumption extension function module 9L. Compared to 9Lah, it is configured to be shorter (8bh <9Lah).

  Therefore, as shown in FIG. 8A, the fitting recesses 8Ha of the high power consumption extension function module 9H or the low power consumption extension function module 9L can be fitted to the fitting protrusion 8b of the basic module 8. The fitting recess 9La of the low power consumption extension function module 9L can be fitted into the fitting protrusions 9Hb, 9Lb of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the opening depth 9Hah of the fitting recess 9Ha of the high power consumption extension function module 9H having substantially the same length as the protrusion length 8bh of the fitting projection 8b of the basic function module 8 is the low power consumption extension function module 9L. Because the fitting recesses 9La have a length substantially the same as the opening depth 9Lah, and the projection lengths 9Hbh and 9Lbh of the fitting projections 9Hb and 9Lb of the high power consumption extension function module 9H and the low power consumption extension function module 9L are shorter. 8B, the fitting recesses 9Ha, 9La (primary side) of the high power consumption extension function module 9H or the low power consumption extension function module 9L are fitted into the fitting recesses of the high power consumption extension function module 9H. 9Ha (secondary side) cannot be fitted (primary side and secondary side functions even if the fitting convex portions 9Hb and 9Lb are inserted into the fitting concave portion 9Ha to be fitted) Bonding surface of the module is not in contact, it can not be fitted).

  In addition, the shape of a convex part and a recessed part can employ | adopt variously, such as a rectangular parallelepiped (square bar shape), a cylindrical shape (round bar shape), a conical shape, etc., as long as it is the shape which can mutually correspond (it can fit).

  Subsequently, in the fitting mode in FIG. 9, the basic function module 8 is formed with a fitting recess 8 a including a plurality of (two in FIG. 9) recesses 8 a 1 and 8 a 2 in the power supply unit, and the high power consumption expansion function The module 9H and the low power consumption extension function module 9L are formed with one or a plurality of (one in FIG. 9) recesses 9Ha and 9La in the power supply part, and the high power consumption extension function module 9H. 9 is formed in the power receiving unit of the power supply unit, and one or a plurality (1 in FIG. 9) is provided in the power supply unit of the low power consumption extension function module 9L. The fitting convex part 9Lb which consists of a convex part is formed.

  Then, the number of concave portions of the fitting concave portion 8a of the basic function module 8 (two of 8a1 and 8a2) and the number of convex portions of the fitting convex portion 9Hb of the high power consumption extended function module 9H (two of 9Hb1 and 9Hb2) Is the same number, the number of the recessed portions 9Ha and 9La of the recessed portions 9Ha and 9La of the high power consumption extension function module 9H and the recessed portion of the low power consumption extension function module 9L and the fitting protrusion of the low power consumption extension function module 9L. The number of convex portions (one) of the portion 9Lb is the same, but the number of concave portions (two of 8a1 and 8a2) of the fitting concave portion 8a of the basic function module 8 is the number of the low power consumption extended functional module 9L. Compared to the number (one) of convex portions of the fitting convex portion 9Lb, the number of convex portions is greater.

  Therefore, as shown in FIG. 9A, the fitting convex portions 9Hb and 9Lb of the high power consumption extension function module 9H or the low power consumption extension function module 9L can be fitted into the fitting recess 8a of the basic module 8. The fitting protrusion 9Lb of the low power consumption extension function module 9L can be fitted into the fitting recesses 9Ha and 9La of the high power consumption extension function module 9H and the low power consumption extension function module 9L.

  On the other hand, the convex portions 9Ha19Ha1 of the fitting convex portions 9Hb of the high power consumption extension function module 9H having the same number of concave portions 8a as the fitting recesses of the basic function module 8 are the fitting convex portions 9Lb of the low power consumption extension function module 9L. 9B, since the number of convex portions is larger than the concave portions of the fitting concave portions 9Ha and 9La of the high power consumption extended function module 9H and the low power consumption extended function module 9L having the same number of convex portions. As shown, the fitting protrusion 9Hb (secondary side) of the high power consumption extension function module 9H is provided in the fitting recesses 9Ha and 9La (primary side) of the high power consumption extension function module 9H or the low power consumption extension function module 9L. Cannot be mated.

  In addition, in FIG. 9, although the aspect from which a primary side becomes a recessed part was demonstrated, it can apply also to the aspect from which a primary side becomes a convex part like FIG.7 and FIG.8. Moreover, as long as the shape of a convex part and a recessed part is a shape which mutually respond | corresponds (it can fit), a rectangular parallelepiped (square bar shape), a cylindrical shape (round bar shape), a cone shape, etc. are employable variously.
