In the radio-controlled clock, what determine receptivity is antenna performance and receiving circuit characteristic.
As the type of antenna, because the wavelength of standard wave reaches about 5 kms (km), be difficult to carry out the resonance of wavelength direction in wrist-watch inside, so general use coiling coil of conductive wire shape stick antenna on the magnetic core of formations such as ferromagnetism body.The magnetic flux that utilization penetrates this stick antenna obtains electromotive force on coil.
Receiving circuit is according to the output detection time information of antenna and passes to the circuit of clock with movement.Clock is meant with movement battery and clock is operated the composite component that the circuit units such as timing circuit that need collect in 1 device.According to circumstances, also comprise character disc and LCD equal time display device sometimes.
The Wristwatch-type radio-controlled clock also has the effect of being used as handicraft except that the function of being used as clock, so design and texture are very important.As the especially important factor of the feeling of high class of clock, wish that it is the metal external packing that constitutes the external packing of clock main body with metal.
But when packing the metal external packing into, the output of antenna extremely reduces.This is that standard wave is difficult to enter clock inside because metal external packing surface produces eddy current, and the anti-magnetic flux that the eddy current that produces of metal external packing surface causes hinders the magnetic flux that is produced by the electric current that circulates in the antenna, thereby hinders the electric current that circulates in the antenna.
That is,, there is the problem that is difficult to the acceptance criteria electric wave though the Wristwatch-type radio-controlled clock is wished the metal external packing.Therefore, attempt proposing many technology that also can receive with the metal external packing.For example, improve the technology of antenna pattern.By improving the receiving sensitivity of antenna, can receive more standard wave.
The Wristwatch-type radio-controlled clock uses the situation of stick antenna more as illustrating, thus the technology (for example with reference to patent documentation 1, patent documentation 2) that the shape of the magnetic core of known improvement stick antenna improves receiving sensitivity.
Figure 26 is the figure that is used to illustrate the prior art that patent documentation 1 discloses, and for convenience of description, changes picture in the mode that does not break away from its purport.Among Figure 26, the 100th, clock outer packaging, the 102nd, magnetic core, the 103rd, the coil of reeling at the long side direction of magnetic core 102, the 104th, the extension of magnetic core 102.Coil 103 fine rule of in fact neatly reeling, but be shown tubular among the figure, so that watch.In addition, also omit and do not need the part that illustrates.
As shown in figure 26, the prior art that patent documentation 1 discloses is equipped with extension 104 in the both sides of magnetic core 102, makes this extension 104 towards unshowned perspex side, thus for the standard wave from the incident of perspex side, with more flux channeled to magnetic core 102.
Figure 27 is the figure that is used to illustrate the prior art that patent documentation 2 discloses, and for convenience of description, changes picture in the mode that does not break away from its purport.Among Figure 27, the 100th, clock outer packaging, the 102nd, magnetic core, the 103rd, the coil that the long side direction of past magnetic core 102 is reeled, the 104th, the extension of magnetic core 102, the 106th, the electric wave collecting board of connection extension 104.With Figure 26 in the same manner, also coil 103 is shown tubular, so that watch.In addition, also omit and do not need the part that illustrates.
As shown in figure 27, the prior art that patent documentation 2 discloses is carried out layout, the extension 104 of magnetic core 102 is connected with electric wave collecting board 106, and interior crooked toward clock external packing 100.Utilize such formation, the more standard wave that enters in the clock external packing 100 can be directed to magnetic core 102, but also increase the direction of radio-controlled clock acceptance criteria electric wave.The Wristwatch-type radio-controlled clock is worn on the wrist, makes its direction do various variations according to the action of human body, so effectively increase the direction that can receive electric wave.
Patent documentation 1: the spy open the 2005-3675 communique (the 15th page, Figure 11)
Patent documentation 2: the spy open the 2004-235701 communique (the 5th～7 page, Fig. 3)
Summary of the invention
The prior art that patent documentation 1, patent documentation 2 disclose, the both considers clock external packing 1 is taken as the situation of metal external packing, makes to make this metal external packing not hinder flowing of magnetic flux.Yet, distinguish that these structures can not receive more standard wave.
That is, the prior art extension 102 that patent documentation 1 discloses only extends magnetic core, so when the unshowned perspex side of clock external packing 1 was seen, extension 102 was less in the plane, forms to receive more standard electric wave structure.With this structure, can not effectively obtain magnetic flux.
Further, when the top of antenna was equipped with character disc or LCD equal time display device, they cut off standard wave, so even effectively acceptance criteria electric wave of extension 102 is arranged.
The prior art that patent documentation 2 discloses is when the unshowned perspex side of clock external packing 100 is seen, electric wave replenishes portion 115 and forms fan-shaped, though so be fit to and be directed to magnetic core from the standard wave of perspex side incident, but the prior art that discloses with patent documentation 1 in the same manner, when electric wave replenishes the top outfit time display apparatus of portion 115, they cut off standard wave, and electric wave replenishes effectively acceptance criteria electric wave of portion 115.
, Wristwatch-type radio-controlled clock is in recent years wished further miniaturization, and the miniaturization of clock external packing constantly makes progress.Yet in order further to be convenient to viewing time information, time display apparatus is with greatly good as far as possible.For example, when time display apparatus is taken as pin type simulation character display dish, its pin of overstriking etc. of constantly trying every possible means.
That is, there is the situation that causes more and more being difficult to the acceptance criteria electric wave because of the maximization of time display apparatus or pin.
In addition, in the wrist-watch that constitutes with the metal external packing, antenna end is undue during near the metal external packing, produces eddy current loss between metal external packing and antenna, causes the impaired state of antenna gain.In addition, when antenna connected the metal external packing, the eddy current that circulates in antenna and the metal external packing reduced antenna output.Therefore, need make antenna and external packing separate suitable distance.
Further, antenna inside also produces the loss that eddy current and magnetic hysteresis loss cause, so when antenna too maximized, the influence of these resistance factors made antenna gain impaired greater than the collection efficiency of magnetic flux on the contrary.
In addition, maximize when improving the self-induction of antenna by antenna, the self-resonant frequency of antenna reduces, and the frequency band that can use as antenna narrows down.
As described above illustrated, the prior art that patent documentation 1, patent documentation 2 discloses can not be taken into account to make as the time display apparatus of the usefulness of giving the correct time of the original purpose of clock and not only be convenient to watch but also receive more standard wave.

Embodiment
Antenna of the present invention is provided with: the magnetic core of the column that is made of the ferromagnetism body, be wound on the coil portion on the magnetic core, the flat extension that extends from the end of magnetic core and the rise part that is provided at least one direction surface of extension.This direction surface is meant any direction surface of extension thickness direction.
Preferably do extension bigger, can be toward the shape of the either side bending of extension thickness direction.
Extension and rise part are made up of the ferromagnetism body, and be not overlapping in the plane with the coil that is wound on the magnetic core.As long as magnetic core, extension and rise part form magnetic coupling, they can be formed with being integrated, connected after also can becoming by minute solid figure.
By being taken as this formation, especially antenna is received when installing to the metal external packing, also can provide to obtain highly sensitive radio receiving equipment more flux channeled to magnetic core.
(antenna explanation: Fig. 1, Fig. 2, Fig. 3)
Below, as an example of the radio receiving equipment that comprises antenna of the present invention, describe with the embodiment 1 of accompanying drawing to the radio-controlled clock that comprises antenna of the present invention.Fig. 1 is the figure of the antenna pattern among explanation the present invention, and Fig. 2 is that the figure that installs to the structure in the radio-controlled clock is received in explanation.
Among Fig. 1, the 2nd, magnetic core, the 3rd, be wound on the coil of the long side direction of magnetic core 2, the 4th, extension, the 5th, rise part, the 16th, antenna, the 21st, the end of magnetic core.In fact coil 3 neatly is wound on magnetic core 2 with fine rule, but is shown tubular among the figure, so that watch.
Among Fig. 2, the 1st, clock external packing, the 8th, character disc or LCD equal time display device, the 7th, the cassette tape portion of the unshowned belt of fastening, the 9th, clock movement.
The top of rise part 5 past accompanying drawings shown in Figure 1 is to the example that forms.Rise part 5 also is made up of the ferromagnetism body, as long as and extension 4 magnetic couplings, be not particularly limited, but also they can be formed as one.
In addition, the material as constituting extension 4 and rise part 5 is not particularly limited, but preferred nonconductor, so that the loss that eddy current is caused reduces.Yet, because the problem on intensity and the manufacture method etc., also can consider to use the good conductor of amorphism etc.Under this situation, when using metal, make extension 4 contact clock external packing 1 with rise part 5 as the constituent material of clock external packing 1, and not conducting on electric certainly.
Among Fig. 2, Fig. 2 (a) schematically illustrates loading time display device 8 in the clock external packing 1, antenna 16 and the clock stereographic map with the state of movement 9.The No.1 direction that each unit is encased in clock external packing 1 that schematically illustrates of arrow.Fig. 2 (b) schematically illustrates from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen.Fig. 2 (c) is the stereographic map that schematically is illustrated in the state clock external packing 1 has been loaded time display apparatus 8, antenna 16 and clock with movement 9 after.
Shown in Fig. 2 (a), Fig. 2 (b), on the top of clock with movement 9, promptly unshowned perspex side is equipped with antenna 16, is equipped with time display apparatus 8 at an upper portion thereof.Overlap extension portion 4 makes it opposed with time display apparatus 8, but rise part 5 being located between the inwall of time display apparatus 8 and clock external packing 1 is unshowned perspex side, it highly is between the inwall of time display apparatus 8 and clock external packing 1, when unshowned perspex skew back is seen the radio-controlled clock that comprises antenna of the present invention, can see rise part 5.
By being taken as this formation, even if clock external packing 1 is a metal, rise part 5 also can receive the standard wave that arrives from unshowned perspex side, it can be directed to magnetic core 2.Time display apparatus 8 is during for character disc for example, by reducing its thickness, also can the acceptance criteria electric wave at extension 4, and so extension 4 also can be directed to the standard wave of receiving at this magnetic core 2.
Certainly, because rise part is arranged to make its inwall along clock external packing 1, so the Yi Jiandu of time display apparatus 8 is not impaired, attractive in appearance yet not impaired as clock.
In addition, as mentioned above, during extension 4 undue maximizations, the influence of the loss that the eddy current of antenna inside and magnetic hysteresis loss cause is bigger than magnetic flux collection efficiency, makes antenna gain impaired.In addition, the antenna self-induction is strengthened,, narrow down as the spendable frequency band of antenna so the self-resonant frequency of antenna reduces.Therefore, need make the scale of extension 4 is the scale of the not impaired degree of antenna gain.
Particularly, the inboard of imaginary extended line X of making the end 21 of magnetic core 2 shown in Figure 3 does not exist extension 4 to get final product.The inboard of imagination extended line X is meant an imaginary extended line X and the opposed side of another imaginary extended line X.
Even this is that the magnetic flux of receiving in the inboard of imaginary extended line X also is directed into magnetic core 2 hardly because in the inboard of imaginary extended line X extension 4 is set, the influence of the resistance factor that the antenna maximization brings increases makes antenna gain impaired on the contrary.
(antenna pattern explanation 1: Fig. 4, Fig. 5, Fig. 6)
In addition, Fig. 1, Fig. 2 illustrate the example that rise part 5 is located at the end of extension 4, but are not limited thereto.Fig. 4 illustrates rise part 5 is located at the top portion of extension 4 and the figure of the example between the end.In addition, Fig. 5 is illustrated in the figure that extension 4 is provided with the example of a plurality of rise parts 5 separatedly.Fig. 6 illustrates the figure that rise part 5 is embedded the example of the slit of time display apparatus 8 or hole portion.

Among Fig. 4, rise part 5 is located between the top portion and end of extension 4.Rise part 5 has to be collected the magnetic flux that circulates abreast with time display apparatus (for example character disc) and makes it flow to the effect of extension.Therefore, even rise part 5 is not configured between the inwall of time display apparatus 8 and clock external packing 1, also can receive the standard wave of time of break-through display device at rise part 5.
By being taken as this formation because rise part 5 is covered by time display apparatus 8 fully, so also applicable to the radio-controlled clock of identical in the past design.
Further, by a plurality of rise parts are set as shown in Figure 5 separatedly, can receive the more magnetic flux that circulates abreast with time display apparatus, so can improve receiving sensitivity.In addition, at rise part 5 slit is set here, but the slit can be set, also can be the structure that dual rise part 5 is set like that shown in Fig. 5 (c).
In addition, among Fig. 5, the height of rise part 5 is inhomogeneous, but is not limited thereto, after can considering jointly with the external packing volume inside of radio-controlled clock the rise part quantity that is provided with, and suitably setting.
In addition, as shown in Figure 6, can make at time display apparatus 8 hole portion 81 is set, and embed the rise part 51 that is located at extension 4 in this hole portion.Like this, when time display apparatus 8 being taken as for example character disc, can be with rise part 51 as identification means (so-called hour pointing character).
When constituting like this, rise part 51 forms one with time display apparatus 8, and scope of design is wide, and and when rise part 5 being configured between the inwall of time display apparatus 8 and clock external packing 1 in the same manner, rise part 51 can receive more magnetic flux, so the receiving sensitivity of antenna is improved.
During this constitutes, also can consider the shape of the external packing of radio-controlled clock, suitably set the shape and the quantity of rise part 51.
(antenna pattern explanation 2: Fig. 7, Fig. 8)
The shape of the rise part 5 of antenna 16 is not limited to as Fig. 1 to the shape that is located at unshowned perspex side shown in Figure 6.Fig. 7 illustrates the figure of example that rise part 5 is located at the dorsal part of radio-controlled clock, forms to make it surround clock with movement 9.Fig. 8 illustrates rise part 5 is located at unshowned perspex side and the figure that carries on the back the example that covers side.
Among each figure, (a) stereographic map that schematically illustrates is shown, (b) illustrate schematically illustrate from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen radio-controlled clock of the present invention.Among Fig. 7, Fig. 8, the 30th, back of the body lid.Give same numbering to the formation that has illustrated.
When being taken as this shape, can receiving from the side or the back of the body of clock external packing 1 and cover the standard wave of 30 sides arrival.
Radio-controlled clock also exists and takes and be placed on the situation that desk etc. is located except that the state that is worn over human body.In view of the behaviour in service of this radio-controlled clock, make the rise part 5 of the part that receives electric wave big or towards a plurality of directions, be equivalent to increase direction and the area that receives electric wave, so can more many standard wave than receive in the past.
To all constituting clock external packing 1 raisings such as texture of clock are described with metal.Even in this case, unshowned rubber blanket by being located at clock external packing 1 and the connecting portion of unshowned table handle or switchgear or be arranged on the back of the body cover 30 with the unshowned rubber system seal of the telescoping part of clock external packing 1 etc. also acceptance criteria electric wave slightly, thereby the part of increasing reception electric wave gets final product as mentioned above.
In addition, exist a part or the back of the body to cover 30 situation with resin formation clock external packing 1.In this case,, standard wave covers 30 arrivals because passing through a part or the back of the body of clock external packing 1, when therefore strengthening the part of reception electric wave, and can be effectively with more flux channeled to antenna.
(the explanation of antenna structure and configuration: Fig. 9)

Certainly, even all form clock external packing 1 with metal, as previously described, by be located at the back of the body cover 30 with the unshowned rubber system seal of the telescoping part of clock external packing 1 etc. also acceptance criteria electric wave slightly, institute carries on the back that to cover 30 be effective so that extension 4 is close.
(explanation of diamagnetic plate structure: Figure 10, Figure 11)
Then, with Figure 10 and Figure 11 the embodiment 3 of the radio-controlled clock that comprises antenna of the present invention is described.Figure 10 (a) illustrates the antenna of explanation among the present invention, the clock stereographic map with the position relation of movement and diamagnetic plate, Figure 10 (b) illustrate schematically illustrate from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention.Figure 11 is the vertical view of the shape of the diamagnetic plate of explanation.Among Figure 10, Figure 11, the 24th, diamagnetic plate, the 99th, pointer drive motor.Give same numbering to the formation that has illustrated.
In order to receive more standard wave, preferably radio-controlled clock is not for to hinder magnetic flux to enter the structure of the inside of clock external packing 1, but because pointer drive motor 99 also has coil, so, tend to have influence on the work of pointer drive motor 99 by influence from the magnetic flux of outside.When the work of the pointer drive motor 99 that notifying time information is used is not accurately carried out, promptly enable accurate acceptance criteria electric wave, as accurately timing of clock.
Therefore, diamagnetic plate 24 is set between clock is with movement 9 and time display apparatus 8, prevents influence from the magnetic flux of outside.The particularly important is, diamagnetic plate 24 covers pointer drive motor 99.By being taken as this formation, the magnetic flux that flows into antenna 16 is not hindered by diamagnetic plate 24, and can make clock have diamagnetism with movement 9.
In the example shown in Figure 10, illustrate with the shape that the upper surface of movement 9 covers pointer drive motor 99 example of diamagnetic plate 24 being set, but be not limited thereto, also can be and cover the formation of clock with the side of movement 9 at clock, in addition, also can be the formation that covers upper surface and side.
(the explanation that diamagnetic plate is overlapping: Figure 11)
In addition, as shown in figure 11, also can be extension 4 and be arranged at the rise part 5 of extension 4 and be located at them and clock with the nonoverlapping in the plane shape of diamagnetic plate 24 between the movement 9.
That is, in the example shown in Figure 11, extension 4 is set, but in this formation, forms 2 extensions 4 and cover the formation of clock with the top of movement 9 in two ends 21 of magnetic core 2.In the bottom of 2 extensions 4 during overlapping 1 diamagnetic plate 24, from the acceptance criteria electric wave and be located at the magnetic flux that the extension 4 of an end 21 of magnetic core 2 flows into and flow out to the extension 4 that is located at the other end 21 through the diamagnetic plate 24 of ferromagnetism body, magnetic flux is difficult to flow to magnetic core 2, and the electric wave receiving sensitivity is reduced.
In the example shown in Figure 11, the top that diamagnetic plate 24 is configured to cover pointer drive motor 99 is shown, and with an extension 4 and another extension 4 both nonoverlapping examples, but be not limited thereto certainly.Importantly, make not overlapping in the plane diamagnetic plate 24 in order to avoid the magnetic flux that 2 extensions 4 that bridge joint extends from different ends produce gets final product, even overlapping also passable with the extension 4 that extends from same end with a certain side of 2 extensions 4 that extend from different ends.
(the explanation that extension forms: Figure 12)
Then, with Figure 12 the embodiment 4 of the radio-controlled clock that comprises antenna of the present invention is described.Figure 12 (a) illustrate explanation among the present invention antenna and clock with the stereographic map of the position relation of movement, Figure 12 (b) illustrate schematically illustrate from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention.Among Figure 12,2 extensions are set respectively in an end 21 of magnetic core 2.4a is the 1st extension, and 4b is the 2nd extension, and 4c is the 3rd extension, and 4d is the 4th extension.The 25th, the circuit board that clock is comprised with movement 9, the 26th, the electronic component of this circuit component etc.Give same numbering to the formation that has illustrated.
Even embodiment shown in Figure 12 4 explanations are done antenna than the formation that does not also have the blind area greatly in radio-controlled clock inside.
At the 1st extension 4a and the 2nd extension 4b rise part 5 is set respectively, and erects toward the direction of time display device 8.Be provided with the 3rd extension 4c to such an extent that separate also opposed with the 1st extension 4a.Equally, the 4th extension 4d is provided with to such an extent that separate also opposed with the 2nd extension 4b.
Downside at the 1st extension 4a and the 2nd extension 4b and the 3rd extension 4c and the 4th extension 4d is provided with clock movement 9, and the circuit board 25 that clock is comprised with movement 9 is located between the 1st extension 4a and the 2nd extension 4b and the 3rd extension 4c and the 4th extension 4d.
Do not have at interval thereby do not contact between the electronic component 26 that the circuit board 25 that clock is comprised with movement 9 and this circuit board 25 are loaded and each extension.
That is, the part formation unit of clock with movement 9 is arranged between the extension.By being taken as this formation, make non-blind area between the extension, can effectively utilize the limited space in the clock external packing 1.
In the example shown in Figure 12, the 3rd extension 4c is shown and the 4th extension 4d does not establish the example of rise part 5, but also can be provided with certainly.
By being taken as this formation, the inside of clock external packing 1 does not produce the blind area, the magnetic flux of 30 these 3 directions of collecting to cover from the side of unshowned perspex side, clock external packing 1 and the back of the body.In addition, because extension covering board 25, thereby form the protection of magnetic aspect, can prevent that electronic component 26 is subjected to the influence of magnetic aspect and the malfunction that causes, and can in magnetic core 2, compile more magnetic flux, the electric wave receiving sensitivity is improved.
(explanation of antenna: Figure 13, Figure 14, Figure 15)
Then, the embodiment 5 to the radio-controlled clock that comprises antenna of the present invention describes.Figure 13 (a) schematically illustrates the stereographic map of radio-controlled clock of the present invention with the shape of antenna, and Figure 13 (b) schematically illustrates the stereographic map that is used to illustrate the configuration in the radio-controlled clock.
Among Figure 13, the 11st, the perspex on the top that is located at clock external packing 1 or the top rise part that instrument bezel is used are installed, the 12nd, the inwall end face of clock external packing 1.The 13rd, the upper opening end face of top rise part 11.In addition, give same numbering to the formation that has illustrated.
Among Figure 13, compare, show extension 4 little, but as long as, also can as enforcement mode 1, strengthen extension 4 greater than the end 21 of magnetic core 2 with Fig. 1 in the embodiment 1.That is, because the area of the platen surface of extension 4 is during greater than the area of the end 21 of magnetic core 2, the area that receives magnetic flux increases, so the electric wave receiving sensitivity is improved.
As mentioned above, rise part 5 has and collects the magnetic flux that circulate abreast with time display apparatus (for example character disc) and make it flow to the effect of covering the extension 4 of 30 direction existence in the back of the body.Therefore, rise part 5 and extension 4 are preferably and make magnetic flux be convenient to material in the circulation of their orthogonal directions, and the most handy ferrite etc. does not have anisotropic ferromagnetism body and constitutes.
Rise part shown in Figure 13 5 is not for there being complicated shape, and the square shape of Wan Qu shape for example is so promptly use ferrite to constitute also impact resistance height.In the radio-controlled clock, use, the accident situation such as fall so run into sometimes because the Wristwatch-type radio-controlled clock is worn on one's body.In this case, its rise part 5 of antenna of the present invention can not damage yet.
Further, when constituting magnetic core 2, extension 4 and rise part 5 respectively with minute solid, the simple shape of each element makes various piece be convenient to make.Even in clock external packing 1, also can make the mutual magnetic coupling of various piece and do not disturb other element with labyrinth.That is, can constitute and avoid constituting the antenna pattern that the space vacated behind the element of clock matches.In addition, hereinafter set forth the device that magnetic core 2, extension 4 and rise part 5 are connected respectively.
Figure 14 schematically illustrates from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention.Among Figure 14, the 50th, the horizontal end face of rise part 5.Dotted line A is an imaginary line, and L1 is the distance of upper opening end face 13 and horizontal end face 50.
In order to collect more magnetic flux, the scale of preferred rise part 5 is big as best one can, but when constituting clock external packing 1 with metal, such as already described, clock external packing 1 and rise part 5 both can not be too in approaching, horizontal end face 50 and the inwall end face 12 or the upper opening end face 13 of rise part 5 separate.
Yet even horizontal end face 50 separates with inwall end face 12, top rise part 11 covers the upper surface of rise part 5 as the brim of a hat, also flows into because of top rise part 11 hinders magnetic flux.
Promptly, in order to collect more magnetic flux not only but also do not hinder magnetic flux flow to go into, from flowing into more magnetic flux side (being the top of accompanying drawing the example of Figure 14), it is good that rise part 5 is not covered (for example instrument bezel or top rise part 11) by the member of clock external packing 1 or connected identical material.
Thereby, as shown in figure 14, the horizontal end face 50 of rise part 5 is can be shown in Figure 14 (a) consistent with upper opening end face 13 in the plane or be arranged in shown in Figure 14 (b) than the center position (center position of the clock external packing 1 of accompanying drawing) of upper opening end face 13 near clock external packings 1.
Figure 14 (a) illustrates upper opening end face 13 and horizontal end face 50 consistent state on plane on the imaginary line A.In addition, Figure 13 (b) illustrates the state that upper opening end face 13 and horizontal end face 50 separate with distance L 1.
In the example, compare shown in Figure 14 (b), show as 11 miniaturizations of top rise part, but be not limited thereto certainly with the figure shown in Figure 14 (a).Need only the shape that changes antenna 16 in the modes such as length that change coil 3 or extension 4, the horizontal end face 50 of rise part 5 both can not with upper opening end face 13 is overlapping in the plane.
Among Figure 14, the situation that unshowned perspex is set in each upper opening end face 13 opposed part is more, therefore by being taken as this formation, can effectively collect, the sensitivity of radio-controlled clock is improved from the magnetic flux of perspex side time of break-through display device.
Figure 15 is the figure of another shape of explanation antenna of the present invention.Figure 15 (a) enlarges rise part 5 in a direction, be trapezoidal thereby make its cross section, rather than Figure 13, square shape shown in Figure 14.For example, by unshowned time display apparatus side is enlarged, can be with the bigger area magnetic flux of direction since then of collecting.
Certainly, just easily will flux channeledly arrive magnetic core 2 also can, Figure 15 (b) is the one example.This example is a parallelogram by the end face that makes rise part 5, will be directed to magnetic core 2 swimmingly by extension 5 from the magnetic flux of rise part 5.
The shape of rise part 5 shown in Figure 15 is examples, is not limited thereto certainly.Importantly, the direction that past electric wave arrives enlarges the face of rise part 5, perhaps manages to make the shape of rise part 5 to do to such an extent that get final product to magnetic core 2 flux channeled easily.
Above supposing in the figure of Figure 15 setup time display device or during perspex, by being taken as this formation, can the sensitivity of radio-controlled clock further be improved from the effective trapped flux of this side.
(the explanation of the different structure of antenna: Figure 16)
Then, the embodiment 6 to the radio-controlled clock that comprises antenna of the present invention describes.This embodiment 6 be can be further the formation of trapped flux well, this is formed in the rise part 5 that is made of magnetic that is connected with extension 4 the poly-magnetic members that are made of magnetic further is set.
Below, describe with the embodiment 6 of accompanying drawing the radio-controlled clock that comprises antenna of the present invention.Figure 16 (a) is the stereographic map that its shape schematically is shown, and Figure 16 (b) schematically illustrates the stereographic map that is used to illustrate the configuration in the radio-controlled clock.
Among Figure 16, the 6th, poly-magnetic member.The 16th, have the antenna of magnetic core 2, coil 3, extension 4, rise part 5, poly-magnetic member 6.Give same numbering to the formation that has illustrated, but for convenience of description, give the numbering 16 identical with the embodiment that has illustrated of the radio-controlled clock that comprises antenna of the present invention to the antenna of embodiment 6.
Poly-magnetic member 6 is made of the ferromagnetism body, through surface of contact and handling part 5 mutual magnetic couplings.For example, can constitute poly-magnetic member 6 with the amorphous laminated piece.
Poly-magnetic member 6 has the unshowned time display apparatus (for example character disc) or the back of the body that are provided with direction toward top rise part 11 and cover 30 opposed writing board shapes, and has and collect the magnetic flux that more and time display apparatus circulate abreast and make it flow to the effect of covering the extension 4 of 30 direction existence in the back of the body.
Poly-magnetic member 6 is bigger with the area that poly-magnetic member 6 is connected than rise part 5, and as what illustrated, preferably poly-magnetic member 6 is big as far as possible in the inside of clock external packing 1.In the example shown in Figure 16, poly-magnetic member 6 has crooked shape, but also can form bigger wing in the mode that is spaced from the inside of clock external packing 1.
In addition, rise part 5 needs the time display apparatus side big to the magnetoconductivity of direction (above-below direction of Figure 16) that the back of the body cover side, but during with amorphous laminated piece formation magnetic core 2, the conducting on electric of magnetic core 2 and poly-magnetic member 6, then eddy current circulates on entire antenna 16, thereby loss increases.Therefore, rise part 5 is preferably insulating material.
In the amorphous laminated piece,,, preferably be not used in rise part 5 so do not satisfy this character because the big direction of the big direction of magnetoconductivity and conductance is consistent.According to above viewpoint, rise part 5 the most handy ferrites constitute.
In the case, because rise part 5 shown in Figure 16 is not complicated shapes such as bending, promptly use ferrite to constitute yet impact resistance height, even radio-controlled clock is impacted, rise part 5 can not decrease ring yet.Certainly, also can make rise part 5 be shape shown in Figure 15.
(explanation of antenna configurations: Figure 17, Figure 18)
Figure 17 schematically illustrates from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention.Among Figure 17, the 60th, the end of poly-magnetic member 6.Dotted line B is an imaginary line, and L2 is the distance of upper opening end face 13 and end 60.
The scale of poly-magnetic member 6 is identical with the example of the extension 4 of the embodiment 1 of the radio-controlled clock that comprises antenna of the present invention, in order to collect more magnetic flux, preferably it is big as best one can, but when constituting clock external packing 1 with metal, such as already described, clock external packing 1 and poly-magnetic member 6 both can not be too in approaching, the end 60 of poly-magnetic member 6 separates with inwall end face 12 or upper opening end face 13.
Yet even end 60 separates with inwall end face 12, top rise part 11 covers the upper surface of poly-magnetic member 6 as the brim of a hat, also flows into because of top rise part 11 hinders magnetic flux.
Promptly, in order to collect more magnetic flux not only but also do not hinder magnetic flux flow to go into, from flowing into more magnetic flux side (being the top of accompanying drawing the example of Figure 17), poly-magnetic member 6 is not covered as good by the member of clock external packing 1 or connected identical material (for example instrument bezel or top rise part 11).
Thereby, in the example shown in Figure 17, the end 60 of poly-magnetic member 6 is can be shown in Figure 17 (a) consistent with upper opening end face 13 in the plane or be arranged in center position (center position of the clock external packing 1 of accompanying drawing) than the 13 close clock external packings 1 of upper opening end face shown in Figure 17 (b).
Figure 17 (a) illustrates upper opening end face 13 and end 60 consistent state on plane on the imaginary line B.In addition, Figure 17 (b) illustrates the state that upper opening end face 13 and end 60 separate with distance L 2.
With example shown in Figure 14 in the same manner, among Figure 17, the situation that unshowned perspex is set in each upper opening end face 13 opposed part is more, so by being taken as this formation, from the perspex side, poly-magnetic member 6 is the plane, even there is unshowned character disc etc., also can be further effective trapped flux, the sensitivity of radio-controlled clock is improved.
In addition, in the example shown in Figure 17, poly-magnetic member 6 is located at than the direction of rise part 5 away from magnetic core 2, but is not limited thereto, also can be located at, also can all be provided with at this both direction than the direction of rise part 5 near magnetic core 2.But, when near the direction of magnetic core 2 poly-magnetic member 6 being set than rise part 5, with the situation of the extension 4 of setting forth previously in the same manner, be wound on the coil 3 of magnetic core 2, the extension 4 that extends from the different ends of magnetic core 2 and therewith extension 4 magnetic-coupled poly-magnetic members 6 need not overlapping in the plane.
Figure 18 similarly schematically illustrates from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention with Figure 17.It illustrates rise part 5 and poly-magnetic member 6 cover the example that 30 direction disposes toward the back of the body.
Among Figure 18, constitute the back of the body with insulating material and cover 30.The 14th, clock external packing 1 is covered the 30 lower openings end faces that are connected with the back of the body.Dotted line C is an imaginary line, and L3 is the distance of lower openings end face 14 and end 60.Give same numbering to the formation that has illustrated.
Wrist-watch has the effect of being used as handicraft, is purpose to require texture for the character disc that should be called clock face therefore, uses hardware under many situations.When constituting character disc with metal, magnetic flux is shielded, so significantly reduce from the inflow of the magnetic flux of character disc side (unshowned perspex side).
Therefore, as shown in figure 18, constitute the back of the body with insulators such as plastics and cover 30, and rise part 5 and poly-magnetic member 6 are configured in the back of the body cover 30 sides, thereby cover 30 sides and obtain magnetic flux from carrying on the back effectively.
The scale of poly-magnetic member 6 is identical with example shown in Figure 17, and in order to collect more magnetic flux, preferably it is big as best one can, but during with the external packing 1 of metal formation clock, clock external packing 1 and poly-magnetic member 6 both can not be too in approaching.For the end 60 of poly-magnetic member 6, lower openings end face 14 covers the upper surface of poly-magnetic member 6 as the brim of a hat, hinders magnetic flux to flow into.
That is, in order to collect more magnetic flux not only but also do not hinder magnetic flux flow to go into, from flowing into more magnetic flux side (being the below of accompanying drawing the example of Figure 18), poly-magnetic member 6 is not covered as good by clock external packing 1.
Thereby, in the example as shown in figure 18, the end 60 of poly-magnetic member 6 is can be shown in Figure 18 (a) consistent with lower openings end face 14 in the plane or be arranged in center position (center position of the clock external packing 1 of accompanying drawing) than the 14 close clock external packings 1 of lower openings end face shown in Figure 18 (b).
Figure 18 (a) illustrates lower openings end face 14 and end 60 consistent state on plane on the imaginary line C.In addition, Figure 18 (b) illustrates the state that lower openings end face 14 and end 60 separate with distance L 3.
In the example shown in Figure 180, be provided with antenna 16 adjacent, but also can be provided with to such an extent that cover 30 adjacent certainly with the back of the body with time display apparatus 8.Importantly, with rise part 5 or poly-magnetic member 6 towards approaching side facing to magnetic flux.
By being taken as this formation, can cover side from the back of the body and collect more magnetic flux, the sensitivity of radio-controlled clock is improved.
(the explanation of the different structure of antenna: Figure 19)
Figure 19 is the figure of other shape of explanation antenna of the present invention.Figure 19 (a) enlarges the past direction of the thickness of poly-magnetic member 6, and the figure of non-homogeneous writing board shape.For example, by enlarging thickness toward unshowned time display apparatus side, also can trapped flux from its side, so can three-dimensional ground trapped flux.Certainly, just easily will be flux channeled to magnetic core 2 also can, Figure 19 (b) is a parallelogram by the cross section that makes poly-magnetic member 6 equally, future, autohemagglutination magnetic member 6 magnetic flux was directed to extension 4 swimmingly.
The shape of poly-magnetic member 6 shown in Figure 19 is examples, is not limited thereto certainly.Importantly, the direction that arrives facing to electric wave forms poly-magnetic member 6 with stereo structure, or manages to make the shape of poly-magnetic member 6 to do to such an extent that get final product to magnetic core 2 flux channeled easily.
Suppose above the accompanying drawing of Figure 19 the setup time of display device or during perspex, by being taken as this formation, can be from the effective trapped flux of this side, but example constitutes the back of the body with insulating material like that and cover 30 o'clock as shown in figure 18, can make same structure cover 30 sides towards carrying on the back certainly.
(explanation of the unitized construction of extension 4 and rise part 5, poly-magnetic member 6: Figure 20～Figure 24)
Then, the unitized construction of extension 4 with rise part 5, poly-magnetic member 6 described, Figure 20 to Figure 24 is the figure that the formation that connects these parts is described, the 19th, fixed component, the 20th, screw, the 22nd, bolt, the 23rd, pad, the 28th, augmentor, the 40th, nut.52 are provided in a side of the rise part lug boss of the protuberance shape of rise part 5, and 53 are provided in a side of the recess of rise part 5, and 55 are provided in a side of the groove of the kerf of rise part 5.62 are provided in a side of the hole portion of poly-magnetic member 6, and 63 are provided in a side of the poly-magnetic member lug boss of the protuberance shape of poly-magnetic member 6.Give same numbering to the formation that has illustrated.
Among Figure 20, Figure 20 (a) and (b) explanation a certain side of rise part 5 and poly-magnetic member 6 is provided with embeded slot and the opposing party is provided with and the shape of embeded slot engagement and the formation that both sides are meshed.Figure 20 (a) is illustrated in the example that poly-magnetic member 6 is provided with embeded slot, and Figure 20 (b) is illustrated in the example of rise part 5 configuration embeded slots.By making this formation,, the magnetic coupling degree is increased to increase the contact area of rise part 5 and poly-magnetic member 6.
Figure 20 (c) illustrates that making the rise part 5 and the composition surface of poly-magnetic member 6 is the figure of the formation of zigzag fashion.By making this formation, increase both sides' contact area, the magnetic coupling degree is increased.
Figure 20 (d) is explanation makes its chimeric formation to the rise part lug boss 52 of the hole portion 62 break-through rise parts 5 of poly-magnetic member 6 figure.By making this formation, both sides are firmly connected mutually, and increase the magnetic coupling degree.
Figure 20 (e) formation chimeric that be the poly-magnetic member lug boss 63 that makes poly-magnetic member 6 with the recess of rise part 5 53.Certainly, with the example shown in above-mentioned Figure 20 (d) in the same manner, also can the rise part lug boss be set at rise part 5, at poly-magnetic member 6 recess is set, the rise part lug boss that be located at rise part 5 this moment also can not connect poly-magnetic member 6.
To be explanation be provided with groove and sandwich the figure of the formation of poly-magnetic member 6 in groove at rise part 5 Figure 21.The groove 55 of kerf is roughly the same or big some and form with the thickness of poly-magnetic member 6, thereby it is fixing will to gather magnetic member 6.
Can form the formation of the groove 55 that this kerf is set simply.This is because can constitute the rise part 5 of square shape with known process technologies such as cuttings.By making this formation, can connect rise part 5 and poly-magnetic member 6 simply, and can increase the magnetic coupling degree.
Figure 22 is the figure of explanation to the formation of the fixedly use fixed component 19 of extension 4, rise part 5, poly-magnetic member 6.Fixed component 19 has for example C shape, sandwiches these members and it is fixed.By making this formation, can increase the magnetic coupling degree.
The shape of fixed component 19 is not limited to the C shape.Though not shown, also can be taken as ring-type, extension 4, rise part 5, poly-magnetic member 6 break-through are also fixed.The material of fixed component 15 is an insulating material, preferably has elasticity to a certain degree, and for example available plastics constitute.
Figure 23, Figure 24 are that explanation clamps rise part 5 and poly-magnetic member 6 with screw mechanism and the figure of fixing example.Augmentor 28 is as long as produce the clamping of acting force antagonism screw 20, and what can; Use leaf spring in Figure 23, the example shown in Figure 24.Certainly, also can be with spring or spring washer.Screw mechanism is meant with the mechanism that member is fixing such as the mode that applies these screws 20, packing ring 23 or augmentor 28 etc.
Figure 23 (a) illustrates with screw 20 and packing ring 23 rise part 5 and poly-magnetic member 6 is clamped and fixing example.
Figure 23 (b) also illustrates the example that uses augmentor 28 to be fixedly clamped.Owing to utilize augmentor 28 appropriateness to apply acting force, therefore can finish being fixedly clamped of further reinforcement, and when antenna of the present invention is loaded in radio-controlled clock, can prevent that the vibration that produces etc. from causing screw lax when using this clock.By making this formation, can increase the magnetic coupling degree.
In the formation shown in Figure 23, can freely select the scale and the quantity of each unit of formation screw mechanism.In view of the shape and the material of rise part 6 and poly-magnetic member 6, do packing ring 23 bigger, the clamping force of screw 20 is disperseed, damage such as can prevent to split.
Figure 24 further specifies the figure that the formation of damaging such as makes rise part 5 and poly-magnetic member 6 be difficult to produce to split.Figure 24 is similar to the formation of Figure 23 (b), and it is to be used to illustrate the situation of using bolt 22 and nut 40 to replace screw 20, and the cut-open view of its cross sectional shape schematically is shown.
As what illustrated, the material that constitutes rise part 5 and poly-magnetic member 6 is hard brittle material sometimes.At this moment, rise part 5 is screwed into screw 20, then should the time stress that produces tend to make rise part 5 or poly-magnetic member 6 to begin be full of cracks or split.
In order to prevent at extension 4, rise part 5, poly-magnetic member 6 through hole to be set as shown in Figure 24,, clamp by nut 40 at this hole break-through bolt 22 because of easily splitting that material that rise part 5 and poly-magnetic member 6 uses produces.
By making this formation, do not produce stress in rise part 5 and the poly-magnetic member 6 etc. when screw 20 is clamped, thereby damage such as do not split.
The material that constitutes screw, packing ring and the bolt etc. of screw mechanism can freely be selected, for magnetic flux being directed to swimmingly magnetic core 2, preferably constitutes with insulator, though be not particularly limited, available plastics constitute.
In addition, though not shown, the employed screw of element, nut, bolt and screw 20, bolt 22, the nut 40 of clock that formation can be loaded in clock external packing 1 is shared.Certainly, also can tighten jointly with these screws, nut etc.
In addition, Figure 20 connects and composes to formation explanation rise part 5 shown in Figure 23 and poly-magnetic member 6, but these extensions 4 that connect and compose explanation in the embodiment 1 can use with being connected also of rise part 5, also can use different connecting and composing with connection, the rise part 5 of rise part 5 respectively with being connected of poly-magnetic member 6 to extension 4.
More than Shuo Ming extension 4, rise part 5, poly-connecting and composing certainly of magnetic member 6 also can be used in combination mutually.For example, a certain side of rise part 5 shown in Figure 20 and poly-magnetic member 6 is provided with embeded slot and the opposing party is provided with the shape of the engagement of embeded slot therewith, and makes on the basis of the formation that both sides mesh, and also can use fixed component 19 or screw mechanism.In a word, as long as extension 4, rise part 5, poly-magnetic member 6 firmly can be connected mutually, can or use in the scope change that does not break away from the main idea that has illustrated.
(the explanation of rise part: Figure 25)
Then, the embodiment 7 to the radio-controlled clock that comprises antenna of the present invention describes.With Figure 25 this embodiment 7 is described.Figure 25 schematically illustrates from 3 o'clock direction or the end view drawing of the state when 9 o'clock, direction was seen the radio-controlled clock that comprises antenna of the present invention.
8 is time display apparatus among Figure 25, and 15 are provided in a side of the 2nd rise part that is made of the ferromagnetism body on surface of the time display apparatus side of poly-magnetic member 6.Time display apparatus 8 is character discs for example.The 2nd rise part 15 can be used as with the discrete member of poly-magnetic member 6 and constitutes, but with poly-magnetic member 6 magnetic couplings.Give same numbering to the formation that has illustrated.
In the end of poly-magnetic member 6 or its plane or this both sides have the 2nd rise part 15.The poly-magnetic member 6 of Figure 25 (a) is located at the downside of time display apparatus 8, but the 2nd rise part 15 is located at the end of poly-magnetic member 6, and is arranged to be same plane with time display apparatus 8.When time display apparatus 8 was taken as character disc, this character disc was flat state.Among Figure 25, for convenience of description, be drawn as the 2nd rise part 15 is connected with time display apparatus 8, but be spaced from each other according to the material and the structure that constitute them sometimes.
Unshowned perspex is only arranged at the top of time display apparatus 8, no clock external packing.Therefore, from the upper direction trapped flux of time display apparatus 8,, be difficult for producing the loss that eddy current caused easily owing to leave clock shell-side face.Further, utilize the 2nd rise part 15 to make poly-magnetic member 6 form three-dimensional shape, but not tabular, thereby be convenient to from more multi-direction trapped flux.
Certainly,, also make the quantity of the magnetic that constitutes antenna increase the shortcoming minimizing that is caused, can obtain highly sensitive radio-controlled clock by the 2nd rise part 15 is set.
In the formation that Figure 25 (a) illustrates, explanation is located at the 2nd rise part 15 example of the end of poly-magnetic member 6, but only however disturb clock itself design, time display apparatus (for example liquid crystal panel etc.) shape and be located at the time showing pointer etc. of character disc, the 2nd rise part 15 is located at all can Anywhere of the flat shape of gathering magnetic member 6.
Certainly, the 2nd rise part 15 does not constitute tabular surface with time display apparatus 8 and also can, also can be provided with to such an extent that more stretch toward unshowned perspex side, can also can make therefore that the 2nd rise part 15 is unshowy also can to make it as with conspicuous characteristics on the contrary in conjunction with the design of clock than time display apparatus 8.Figure 25 (b) is provided with slit or hole portion at time display apparatus 8, and is arranged to the 2nd rise part 15 is embedded this place.The 2nd rise part 15a is arranged to thereby its same plane that is located at time display apparatus 8 is formed flat condition in the plane, is provided with the 2nd rise part 15b to such an extent that more stretch toward unshowned perspex side than time display apparatus 8.
By such formation, with the rise part 51 of setting forth previously in the same manner, can form the 2nd rise part 15a of flat condition in the plane with time display apparatus 8 with being arranged to and the 2nd rise part 15b that more stretches toward the perspex side than time display apparatus 8 uses as identification means.Therefore, the 2nd rise part 15 becomes one with time display apparatus 8, and scope of design enlarges, and because the 2nd rise part 15 has the part that is not covered by time display apparatus 8, so the 2nd rise part 15 can receive more magnetic flux, thereby the receiving sensitivity of antenna is improved.
In addition, use describes the figure that the 2nd rise part 15 is located at unshowned perspex side among Figure 25, covers 30 sides but also can add to be located to carry on the back.That is, also can cover the side both sides with the back of the body the 2nd rise part 15 is set in the perspex side.
Like this, the shape in conjunction with the radio-controlled clock of antenna can be provided with a plurality of the 2nd rise parts 15, also can change its shape.
Certainly, the 2nd rise part 15 can use the extension 4 and connecting and composing of rise part 5 or connecting and composing of rise part 5 and poly-magnetic member 6 that has illustrated with connecting and composing of poly-magnetic member 6.
In addition, also the rise part 5 that is located at extension 4 can be arranged on unshowned perspex side and cover 30 side both sides with the back of the body.Certainly, also can correspondingly poly-magnetic member 6 be set these both sides.By making this formation, antenna pattern is a stereo structure, can be with more flux channeled to magnetic core 2.
The radio receiving equipment that comprises antenna of the present invention discussed above is to utilize magnetic flux in a single day to enter to constitute the ferromagnetism body of the unit of antenna just to be difficult to the equipment of the characteristic of leaking.Thereby the shape of extension and rise part is not limited to illustrated shape, can change on the degree that does not break away from the invention main idea, and for example the element according to radio receiving equipment inside is provided with slit, hole portion, otch etc. to extension.Especially in the situation of radio-controlled clock, it is more that the situation of various designs is pretended in outsourcing to clock, so can freely select the shape of extension and rise part in conjunction with the design of this clock external packing.
Industrial practicality
Antenna of the present invention can be loaded into the radio-controlled clock that requires to detect more magnetic flux, and is especially suitable In dwindle wasted space and require small-sized and lightweight Wristwatch-type radio-controlled clock as far as possible, in addition, also Can be used for portable radio radio or transceiver etc.
