Description
Technical field
The present invention relates to a kind of new medial support structures, more particularly, relate to the new medial support structures that can be used in support component and make parts ground connection.
In this article, medial support structures specially refers to be arranged on the structure between the supported objects of the frame unit of substantially rigid and substantially rigid, supported object can be fixed on the frame unit or by frame unit to keep.
Background technology
For wrist-watch, be positioned at the train engagement of the gear parts of winding arbor inner end and movement, be positioned at the last bar handle of winding arbor jag by rotation, can adjust the time and the pointer position of demonstration.Perhaps can carry out the adjustment on date by train, pinion wheel part or the similar component of movement.In addition, the popular pattern of wrist-watch is so-called quartz type electronic timer at present.Movement assembles with the integrated circuit (IC) or the circuit piece of controlling and driving or operation crystal oscillator, motor or like.
Yet mechanical connection of introducing above or contact relation cause unexpected electrostatic problem.Promptly, when the last bar handle of the user's of wrist-watch or similar means electrostatic charging Body contact wrist-watch so that when adjusting the time or date that shows, situation shown in Fig. 4 A can appear, static is transmitted to metal parts on the bar handle 110 from user's health through finger, by being connected to the metal winding arbor 120 of bar handle 110, be transmitted to the metal part that comprises with the movement 130 of the train of the gear parts of winding arbor 120 front ends engagement again, arrive the IC140 or the similar elements of movement 130 at last, static is spilt.In this case, static electric weight electromotive force or the voltage very big or health when outflow is very high.Exist the worry that makes IC140 damage or maloperation on IC140 or the like to a large amount of electric currents being arranged on IC140 or the like or having big voltage to be applied to.In addition, when not having directly to arrive the thread guide path of IC140 or like, also exist the worry that effluve is made IC140 or like damage or maloperation.
Known the negative effect that causes for fear of static in the electronic timer, the back of the movement 130 that supports at central frame or similar component is provided with sheet metal, metal spring is arranged between sheet metal and the case rear cover, perhaps form and to lead to the hole of current-carrying part in the movement 130 at the back side of movement 130, metal volute spring is arranged between the conductor and metal case rear cover of bottom, hole, and static is flowed away.But for this quasi-tradition electronic timer, it is difficult to make the size of wrist-watch such as thickness does not increase or the shape of movement 130 is unrestricted guarantees to be provided with spring or the required space of like.
Consider that the various viewpoints of introducing have above proposed the present invention, therefore, an object of the present invention is to propose a kind of new medial support structures, it has two kinds of functions such as intermediate supports function and grounding function, and has minimum size.
Summary of the invention
Another object of the present invention provides a kind of electronic timer with so new medial support structures.
To achieve these goals, medial support structures of the present invention is the medial support structures of elastically deformable, its stock comprises resin, medial support structures comprises the current-carrying part of making by the conduction of disperse in resin stock millimicro carbon pipe, this current-carrying part exposes contact portion with the surface of corresponding conductive body and contacts, and two conductive paths between the conductive body are provided.
Medial support structures of the present invention makes and " this current-carrying part contacts with the surface exposure contact portion of corresponding conductive body " therefore, by the current-carrying part of medial support structures, to be provided with conductive path between (two) conductive body.In addition, according to medial support structures of the present invention, " stock comprises resin; be elastically deformable ", therefore the medial support structures that is different from substantially rigid (for example, medial support structures comprises metal material, as stainless steel), and between the frame unit of the medial support structures of supporting object and substantially rigid or similar component, spring or like are not set, by medial support structures being pressed onto on the frame unit of substantially rigid, supported object can be fixed to frame unit or be kept by frame unit, and the space that occupies like this can reduce.Here, medial support structures provides " current-carrying part of making by disperse in resin stock conduction millimicro carbon pipe " that conducting function and elasticity intermediate supports function are met simultaneously.
" elastic deformation " comprises that shape is easy to elastic deformation that flexural deformation causes and owing to stock comprises that elastic deformation that resin makes the softness of material own cause is (in pressure or similar situation, itself is easy to elastic deformation material) in any situation or the two all comprise, wherein be easy to diastrophic shape and comprise thin-walled disc shape, circular thin-wall shape, thin-walled shape etc.Say in passing, when the hypothesis shape object identical with medial support structures made by metal material such as stainless steel, lack flexibility because material has high degree of rigidity and material itself, in fact this material all be difficult to be considered to elastically deformable in either side and be difficult to not adopt spring or similar object.For resin, for example can adopt polycarbonate resin.Yet any other resin also can use, as long as this resin is fit to form in the above described manner the medial support structures of elastically deformable, and this resin will uniformity ground disperse milli carbon pipe.When the elastic deformation of utilizing the softness of material own to cause, medial support structures generally comprises the outshot that can be pressed onto on other object (generally being the frame unit of rigidity).At least a portion of outshot exposes contact portion as the surface.In this case, the surface exposes the dual-use function that contact portion has support function and grounding function.
In this case, whole medial support structures can be a current-carrying part, and perhaps medial support structures can comprise the non-conductive main part made by disperse millimicro carbon pipe in the resin stock and by with non-conductive main part with current-carrying part is Unitarily molded forms.In this case, medial support structures uses non-conductive part (non-conductive main part) to support supported objects to reduce the influence of static to the object of support usually.In order to form this support, contact can be set engage the surface portion of two parts is contacted with each other, two parts can be worked in coordination or engage by complementary shape is set, or come fastened to each otherly by screw thread or pin, or use other support modes.Yet the object of support also can assign to support by conductive part, as long as the conductive path that is provided with is enough in the position away from supported objects static be flowed away.In addition, in this case, though the volume of the volume that non-conductive main part generally occupies serious offense current-carrying part depends on different situations, current-carrying part can be arranged to the volume of volume greater than non-conductive main part.
According on the other hand, to achieve these goals, medial support structures of the present invention is arranged on the supported objects of substantially rigid and has connected between the framework of substantially rigid of two conductive bodies so that the object that supports is fixed on the frame unit.Medial support structures comprises non-conductive main part and at least one current-carrying part Unitarily molded with main part, non-conductive main part comprises non-conductive millimicro carbon pipe, current-carrying part comprises the millimicro carbon pipe of conduction, current-carrying part is provided with contact portion so that two conductive paths between the conductive body to be provided in two positions on medial support structures surface, at least one is provided with elasticity and is pressed in outshot on the frame unit in non-conductive main part and the current-carrying part.
In this case, according to medial support structures of the present invention, " current-carrying part is provided with contact portion so that two conductive paths between the conductive body to be provided in two positions on medial support structures surface ", therefore two conductive bodies conduct two locational contact portions by current-carrying part.Therefore, an even conductive body in two conductive bodies, as above bar handle, directly be subjected to the effect of static, by two contact portions are set, object is the position that part provides static to flow out therein, as the conductive surface parts of timer, last bar handle constitutes another conductive body, and the conductive component as above static that produces inevitably of bar handle can flow away.Make the negative effect of static can not have influence on electronic component such as IC.
In addition, " framework that has connected the substantially rigid of two conductive bodies " comprises a kind of situation, and wherein all two conductive bodies form the frame unit of part or all substantially rigid; With another kind of situation, wherein in two conductive bodies has constituted the part of rigid frame spare and another is connected to rigid frame spare (example of the last bar handle of introducing above) movably or leggiero basically; Also have a kind of situation, wherein two conductive bodies all are connected to rigid frame spare movably or leggiero." substantially rigid " means that comparing is difficult to be out of shape with the shape of medial support structures or the elasticity of material (elastic deformation easily).
In addition, according to medial support structures of the present invention, current-carrying part is and Unitarily molded the forming of non-conductive main part of medial support structures that therefore, metal spring is different with being provided with in addition, does not need additional space.Therefore, not only the device size that integrates with medial support structures can reduce, and the freedom shape of other parts (as supported object) that are provided with near medial support structures increases.
In addition, according to medial support structures of the present invention, non-conductive main part comprises non-conductive millimicro carbon pipe, current-carrying part comprises the millimicro carbon pipe of conduction, therefore, Unitarily molded non-conductive main part and current-carrying part can be by just electric conductivity be different and form at the essentially identical material of others mutually, so non-conductive main part and current-carrying part can integral body is molded securely form.In addition, non-conductive main part and current-carrying part can strengthen by that be conducted electricity respectively and non-conductive millimicro carbon pipe, and millimicro carbon pipe makes that whole physical strength also obtains increasing.Therefore, non-conductive main part can adopt the 3D shape that geometric configuration arbitrarily or medial support structures adopt.The result is that " bonding part and object mechanical engagement are to support this object " of non-conductive main part can form by desirable complicated shape, therefore, is easy to provide support or engagement function especially non-conductive part.
In addition, according to medial support structures of the present invention, at least one is provided with elasticity and is pressed in outshot on the frame unit in non-conductive main part and the current-carrying part, therefore, be arranged on the supported objects of substantially rigid and connected between the framework of substantially rigid of two conductive bodies and make the outshot elastic deformation by medial support structures, medial support structures can be kept securely by frame unit.Therefore, supported object can be kept by frame unit securely by medial support structures.In this case, when the material of middle supporting construction is soft relatively, but outshot generally by from the basic orthogonal in surface the outshot of the elastic compression of giving prominence to constitute.When the material of middle supporting construction is harder, outshot generally by from surface tilt the chip shape elastic part given prominence to constitute.But if necessary, other form also can.
The quantity of the contact portion on the current-carrying part can be two, and is three or more, preferably at least two.In addition, in fact two contact portions are exactly to constitute the surface on medial support structures surface or the face different with these surfaces.
In addition, for the electric conductivity of medial support structures, " non-conductive " of main part means " it is reach the degree of can distinguishing low that the electric conductivity of main part is compared with current-carrying part ".Therefore, though when current-carrying part has metallic conductivity or conductivity degree, but not the conductive bodies part generally is made of the so-called insulator with high electric insulation performance, decide on condition, non-conductive main part can be semiconductive (being generally semi-conductive electric conductivity or conductivity degree in the temperature range of using).In addition, when non-conductive main part is when being made of a plurality of non-conductive district that current-carrying part separates, all non-conductive districts can be made of similar substantially structure, and one or more non-conductive districts also can be made of different structure mutually.Simultaneously, when current-carrying part is arranged to semiconduction, non-conductive main part generally is made of insulator.In addition as long as there is the difference that can obviously distinguish in non-conductive main part and current-carrying part on electric conductivity, depend on different situations, all non-conductive main parts and current-carrying part can have and generally be called metallic electric conductivity, or the both can have non-conductive (insulating property) that generally are called electrical insulating property, and perhaps both can have semiconduction.In addition when current-carrying part when constituting by the spaced-apart a plurality of conduction regions in the non-conductive district that constitutes a non-conductive main part part, all conduction regions can be made of similar basically structure, perhaps, one or more conduction regions also can be made of mutual different structure.
Assigned to provide conductive path between two conductive bodies as long as the current-carrying part setting is exposed to the contact site of last two positions, non-conductive main part surface, one of them is not that the part of the contact portion that exposes can be arranged in non-conductive main part by any way.In addition.Conductive body can all conduct electricity, or conduct electricity in a part of zone that has comprised the part that contacts with contact portion.In addition, the contact portion of current-carrying part can be positioned at, for example, and the end of elongated current-carrying part, or be positioned at the intermediate portion, in addition, current-carrying part can constitute the loop of ring-type.
The form that is exposed to contact portion can be along the form of the layer on medial support structures surface or from the outstanding outshot in middle supporting construction surface.Under latter event, usually, the contact of contact portion is the front end formation at the teat of current-carrying part, and wherein current-carrying part is outstanding from the surface of non-conductive main part.In addition, depend on different situations, the contact portion of exposure can constitute by elastic protrusion part branch outstanding from non-conductive main part by elastically deformable ground and that be pressed on the conductive body.
In this case, the outshot that is made of the metal spring spare that separates can be used as a current-carrying part and is integrated on the non-conductive main part traditionally, therefore, the electric device that not only is combined into can reduce on the whole, and, be very easy to handle medial support structures by being integrated into medial support structures.In addition, when middle supporting construction by double-colored or polychrome is injection-molded when making, the elongated outshot that millimicro carbon pipe forms can be roughly concordant with the outshot bearing of trend, therefore also increased the bending strength of outshot.
The number of current-carrying part can be one, one, and a row or an one deck also can be a plurality of (for example, a pair of, two, three or more).In this case, the number of the current-carrying part mutual quantity of the current-carrying part of electrical isolation preferably.Therefore, a current-carrying part can be provided with one or more branches or divided portion.
Simultaneously, current-carrying part can embed non-conductive main part, its part except terminal part can partly be exposed to the surface of non-conductive main part, perhaps, near the contact portion that is electrically connected to conductive body, the Zone Full of current-carrying part can be exposed to the surface of non-conductive main part, makes space that medial support structures occupies owing to can reduce with supported object electrical isolation or with supported object capacitive coupling.In this case, non-conductive main part can support supported object by contacting with supported body surface with engaging, or, perhaps be fixed to supported objects and support supported object by connection such as screw or fixture by cooperating or the similar bonding part of mode and the supported object supported object of incompatible support that joins.In addition, though current-carrying part is provided with basically constant or approximate cross sectional shape and the size irrelevant with its longitudinal component, cross sectional shape or certain part that similarly geometric condition can be on bearing of trend are different.
Though, most of millimicro carbon pipe of current-carrying part generally is made up of the millimicro carbon pipe of conduction, as long as the electric conductivity of current-carrying part exceeds the electric conductivity of non-conductive main part fully, a part or the appropriate section of the millimicro carbon pipe of current-carrying part can have low relatively electric conductivity.Though the ratio of appropriate section generally is equal to or less than, for example about 50%, depend on different situations, ratio can surpass about 50%.In addition, whole basically millimicro carbon pipe of current-carrying part can be made up of conduction millimicro carbon pipe.In addition, current-carrying part can mix the component except that millimicro carbon pipe simultaneously.
Similarly, most of millimicro carbon pipe of non-conductive main part generally is made up of non-conductive millimicro carbon pipe, as long as the electric conductivity of non-conductive main part is lower than the electric conductivity of current-carrying part fully, a part or the appropriate section of the millimicro carbon pipe of non-conductive main part can have high relatively electric conductivity.Though the ratio of appropriate section generally is equal to or less than, for example about 50%, depend on different situations, this ratio can surpass about 50%.In addition, whole basically millimicro carbon pipes of non-conductive main part can be made up of non-conductive millimicro carbon pipe.In addition, non-conductive main part can be mixed the component except that millimicro carbon pipe simultaneously.
When the non-conductive main part of middle supporting construction and current-carrying part have by disperse in same or of the same race resin stock that the millimicro carbon pipe of electric conductivity forms separately, the medial support structures operated by rotary motion bossing be used as outshot.In this case, because the rigidity not high (comparing) of resin stock with metal material such as stainless steel, cause bossing elastic deformation that the resin stock forms and bossing is pressed on the frame unit, medial support structures remains on the frame unit regularly.In this case, general bossing forms contact portion, and contact portion has all support functions and grounding function.Yet, also bossing can be arranged on the part outside the contact portion, in addition, part or all of contact portion can be made of bossing.
About millimicro carbon pipe, the millimicro carbon pipe of its electric conductivity or non-conductive current-carrying part that refers to medial support structures and non-conductive main part is conduction or non-conductive, electric conductivity also comprises, electric conductivity is high relatively or low relatively to differentiable degree, usually, conduction millimicro carbon pipe represents to have metallic conductivity, but not the conductive carbon pipe has high relatively electrical insulation capability, as has the semiconductor or the insulator of big band gap.
In addition, well-known, millimicro carbon pipe is (metallic conductivity) or non-conductive (semi-conductive electric conductivity or electrical insulator) of conduction according to its diameter or chirality angle (chiral angle) (helicity) decision.Conduction millimicro carbon pipe can be made of the millimicro carbon pipe with constant diameter or chirality angle, or mixes with the millimicro carbon pipe with different-diameter or chirality angle, as long as the electric conductivity that these millimicro carbon pipes have is more a lot of greatly than the electric conductivity of non-conductive millimicro carbon pipe.The geometrical properties such as diameter of each millimicro carbon pipe can not be constant in addition.Similarly, non-conductive millimicro carbon pipe can be made of the millimicro carbon pipe with constant diameter or chirality angle, or mix with the millimicro carbon pipe with different-diameter or chirality angle, as long as the electric conductivity that these millimicro carbon pipes have is little more a lot of than the electric conductivity of non-conductive millimicro carbon pipe.Though it is short much with even dispersion millimicro carbon pipe that the length of millimicro carbon pipe cans be compared to most the size of non-conductive millimicro carbon pipe on the microcosmic, as long as can the full and uniform carbon of disperse millimicro as one man pipe as the resin of stock, length can be longer.In addition, depend on different situations, can be relatively long so that the bonding between the millimicro carbon pipe is more firm.
Though millimicro carbon pipe generally is made up of so-called individual layer nanotube, as long as can access desired electric conductivity, millimicro carbon pipe can be made up of the millimicro carbon pipe of plural layer (multilayer), or is mixed by the millimicro carbon pipe of individual layer and multilayer.In addition, though millimicro carbon pipe generally just is made of carbon, depend on different condition, carbon atom rather than carbon molecule can be between the surface of nanotube or inner or two pipes.
The non-conductive main part of medial support structures generally is to form by the millimicro carbon pipe that zones of different or part disperse at same resin have different electric conductivity with current-carrying part.Promptly, generally will be respectively in resin material with the ratio of hope and divide uniformly bulk density (when non-conductive main part by the non-conductive part of multiple secondary, when one or more nonconductive resin materials that decide according to kind constitute) the non-conductive millimicro carbon pipe of disperse prepares the nonconductive resin material, with in resin material with the ratio of hope and divide uniformly bulk density (when current-carrying part by multiple secondary current-carrying part, when constituting according to one or more electroconductive resin materials of kind decision) the millimicro carbon pipe of disperse conduction prepares the electroconductive resin material, the hope form of non-conductive main part (zone) and current-carrying part (zone) can be by what is called double-colored or injection-molded Unitarily molded the forming of polychrome.With the millimicro carbon pipe of bulk density disperse in uniform minute in resin, its direction or orientation also can distribute (isotropic) equably, yet, when millimicro carbon pipe integral body is band shape, sheet or linearity, the orientation can be concordant with certain angle, or basically fully longitudinally.In addition, double-colored or multicolor resin injection-molded technology is that the crowd knows (as 1.5.6 chapter double-colored (polychrome) injection molding process of " mould of injection molding apparatus 7 " in the patent figure series that can edit with reference to the Patent Office by discovery and the publication of invention research institute).
As for resin, introduce as top, used polycarbonate.Yet, can use any other resin, as long as this resin be fit to form medial support structures material and can uniformity ground disperse millimicro carbon pipe.
The millimicro carbon tube particle of disperse in the resin or the ratio of powder can be selected arbitrarily according to the character of non-conductive main part and current-carrying part, as long as non-conductive part and current-carrying part can whole formation on medial support structures.From the angle of electric conductivity, at the conductive region (part) that forms by disperse conduction millimicro carbon pipe, the ratio of millimicro carbon pipe is preferably higher.And from the angle of physical strength, when the ratio of millimicro carbon pipe is very high, worry resin as stock, its bulk strength is easy to descend, according to the kind of moving member, the kind of resin or the upper limit that conditions of similarity has a millimicro carbon pipe blending ratio basically.In addition, make the flexibility of resin stock be no more than the elasticity limit, remain on or be higher than predeterminated level, this will become a reference, can the upper limit be set to the quantity of millimicro carbon pipe or the blending ratio of millimicro carbon pipe.Simultaneously, millimicro carbon pipe usually not only has high mechanical properties, but also has elasticity, and therefore, physical strength or elasticity can increase by disperse millimicro carbon pipe in resin.Therefore, from the angle of mechanical property, the ratio of millimicro carbon pipe can be provided with lower limit according to the kind of medial support structures, the kind or the conditions of similarity of resin.Particularly, elasticity is pressed on the conductive body when the contact portion of conductive bodies part is given prominence to also from non-conductive main part, as the spring or the similar component of ground connection.Near current-carrying part has higher proportion at least outburst area reaches conduction millimicro carbon pipe.As mentioned above, upper and lower bound, promptly optimum range is different according to kind, resin kind or the conditions of similarity of medial support structures.
Replace realizing that with the resin stock non-conductive main part and current-carrying part are integrated, have at high proportion or the mechanograph of the medial support structures of highly purified millimicro carbon pipe can be by coming preliminary molded medial support structures with organic material as bonding agent, by heating carry out thermal decomposition or evaporation is burnt cementing agent basically, therefore make millimicro carbon pipe sintering thereafter.In this case, for example, the residue that millimicro carbon pipe is burnt generation by cementing agent is adhered to one another.Yet when millimicro carbon pipe during according to the used medial support structures intensity that obtains wishing adhered to one another, in fact disperse is wherein for residue or similar substance.
In addition, when the static barrier functionality is provided with grounding function or replaces grounding function, medial support structures can be provided with the non-conductive main part that comprises non-static millimicro carbon pipe and the current-carrying part that comprise conduction millimicro carbon pipe Unitarily molded with main part, wherein current-carrying part around the object that will stop so that the restriction disturbing signal enters the object that is blocked.
As above introduced, about medial support structures, the size of medial support structures can reduce, and therefore, medial support structures is suitable for as little electronic components, as the parts of electronic timer such as the quartz type wrist-watch.Compare with the conventional art of simplifying, in two conductive components one corresponding to as above bar arbor, and another is corresponding to the surface elements of electronic timer, such as case rear cover, wherein two conductive components contact with two locational contact portions or two surface exposure contact portions of the current-carrying part of medial support structures.In this case, medial support structures has double action, and an effect is central frame or movement main body part, and another effect is a spring.Naturally, medial support structures can have the effect in other one or more timer part of the central frame of electronic timer or movement main body position, maybe can be as the electronic installation except that electronic timer or the parts of electric mechanical equipment.Simultaneously in zone near to or in contact with the electronics or the electric device element of movement, as the circuit block or the movement itself of IC, timer, spill or flow to IC or circuit block in order to prevent static, this zone can be non-conductive, that is, can be included in the non-conductive main part.

In addition, formed diametric hole 36 in the circumferential wall 35 of housing 30, its opening is opened on the periphery than major diameter recess 32.Patchhole 36 be metal winding arbor 60, its front end gear parts (not shown) engages with pinion wheel part 53 by train.The last bar handle 62 of available finger manipulation is connected to the outboard end of shell end or winding arbor 60.Last bar handle 62 comprises metal part 63 and non-conductive part 64.
More particularly, be provided with the central frame 10 that the composite conducting resin material is made between movement 50 and case rear cover 40, resin material is by disperse and Unitarily molded conduction millimicro carbon are in control equably in resin.Except shown in the cut-open view of the planimetric map of Fig. 1 and Fig. 2 also shown in the skeleton view of Fig. 3, central frame 10 comprises the main part 11 of ring-type basically, substantially four region D of the interval that equates with circumferencial direction B with the axis C that is parallel to timer 1 from the circumferencial direction B along main part 11, E, F and G are projected into the feet part 12d of case rear cover, 12e, 12f and 12g (when relating generally to or do not relate separately to, representing) with 12 with making any distinction between.In addition in area E, feet part 12e is made of at a distance of two the leg part 12e1 and the 12e2 of a determining deviation B along the circumferential direction.The recess 13 that holds winding arbor 60 forms between two leg 12e1 and 12e2.In addition, the bridging part 13a of formation recess 13 bottoms contacts with the front end major diameter part 65 of winding arbor 60.Simultaneously, form two leg part 12g1 and 12g2 at regional G in the position of relative central axis C and leg part 12e1 and 12e2 symmetry.In addition, arrive shown in Figure 3 as Fig. 1, at each leg part 12d, 12e, the base portion of 12f and 12g forms outshot or bossing 14d along the central frame main part of the relative ring plain shape of radial direction, 14e, 14f and 14g (when relating generally to or do not relate separately to, representing) with 14 with making any distinction between, central frame 10 contacts with the periphery than major diameter opening portion 32 of housing 30 and at outshot 14d, 14e (comprising 14e1 and 14e2), the outstanding end of 14f and 14g (comprising 14g1 and 14g2) is supported in housing 30.Basically the circular inner peripheral surface 15 of central frame main part 11 is provided with recess 16a and 16b (representing with 16 when relating generally to or do not relate separately to) can match with the movement 50 that is arranged in the inner peripheral surface inboard (comprising mainboard 51) shape with making any distinction between, simultaneously, form slotted section 55 on the mainboard 51 of movement 50, provide and extended vertically and with making any distinction between, be used to hold the inner circumferential surface 16 and the anterior end surface 17 of the annular body portion 11 of central frame 10 along composition surface 54a and 54b (when relating generally to or do not relate separately to, representing) that diametric(al) is extended with 54.
In addition, as shown in Figure 3, as the main part 11 of the central frame 10 of medial support structures not only can elastic deformation, what be that anchor ring or annular can change that the surface that makes anchor ring or annular becomes according to shape is not annular, can also elastic deformation make any direction distortion of anchor ring or annular, make anchor ring and annular go up the surface that forms and become curved surface around its axis along diameter.In addition, according to central frame 10, it comprises the resin stock, therefore, when middle framework 10 had applied very big external force, the supporting leg part 12 of the outshot of formation axis direction and diametric outshot 14 were under pressure and compare easy deformation within the elasticity limits.
Therefore, when middle framework 10 engages with the bonding part (not shown) of housing 30 when being attached in the timer 1 by the bonding part (not shown) that makes case rear cover 40, relative axis direction, the lower end of supporting leg part 12 or jag 18 are pushed to the front side along the C1 direction by the bottom surface 42 of the inboard recess 41 of case rear cover 40, the part of anterior end surface 17 contacts with the corresponding engagement surface 54b of the mainboard 51 of movement 50, movement 50 is forced into the dial plate 5 of ring plain part 34 supports of housing 30, and movement 50 is fixed to case rear cover 30.
Simultaneously, when middle framework 10 engages with housing 30 by making case rear cover 40, when the relative diameter direction is attached in the middle of the timer 1, the outshot 14 of central frame 10 contacts with the periphery than major diameter opening portion 32 of housing 30 and the inner peripheral surface 16 of the annular body portion 11 by central frame 10 is forced into the corresponding excircle part of movement 50, therefore, movement 50 is fixed to housing 30.
In the process of assembling central frame 10, even be applied to the supporting leg part 12d of central frame 10 with the C1 direction, 12e, power on 12f and the 12g is because exist scale error to have to a certain degree difference, error as shape or similar geometric properties, the main part with annular plate shape 11 of central frame 10 can main part 11 absorbs or the error of balance dimension or shape by twisting within the elasticity limit, make the anchor ring plain bending become curve form, perhaps, supporting leg part 12d, 12e, 12f and 12g compression deformation within the elasticity limit.Similarly, even be applied to the supporting leg part 12d of central frame 10 with diametric(al), 12e, the power on 12f and the 12g is because exist scale error to have to a certain degree difference, as the shape or the similar error of geometric properties, the anchor ring of the annular body portion 11 by making central frame 10 becomes acyclic and looks like elliptical area within the elasticity limit, can absorption or the error of balance dimension or shape, perhaps, within the elasticity limit, make outshot 14d, 14e, 14f and 14g compression deformation.Here, the elastic deformation of central frame 10 be used for by central frame 10 fixedly movement 50 to the shell 3 that comprises housing 30 and case rear cover 40.
According to the electronic timer 1 that constitutes as mentioned above, when the metal part 63 that goes up bar handle 62 with the finger contact when the user of timer 1 is in the state of electrostatic charging is for example carried out time set, shown in Fig. 4 B, the static of user's health is transmitted to the winding arbor 60 of metal from the metal part 63 of last handle 62, successively be transmitted to the bottom bridging part 13a of the recess 13 of the central frame of making by the conductive resin compound material 10 that contacts with diameter major part 65 from the point diameter major part 65 of winding arbor 60, thereafter, the supporting leg part 12 from the central frame 10 made of composite resin material of conduction is transmitted to contacted case rear cover 40.Naturally, the flow direction of the flow direction of electric charge or electric current is just or negative and oppositely according to the finger electric charge.In addition, when right finger in fact with wear when not having Electromotive Difference Of Potential between the left hand wrist of timer 1,, need not worry that in fact electrostatic charge can flow to the IC7 or the like of the movement 50 of timer 1 no matter whether the user is electrically charged.
The result is, when the user of the wrist-watch 1 that is in electriferous state contacts the metal part 63 of bar handle 62, need not worry that electrostatic charge can flow to the IC7 or the like of wrist-watch 1, need not worry that also IC7 or like can damage or maloperation.
As mentioned above, according to wrist-watch 1, the central frame 10 that comprises composite resin material is arranged between movement 50, case rear cover 40 and the housing 30, therefore, uneven stress or very large compressive stress can be absorbed by the elastic deformation of central frame 10, also relate to the shape and the material of central frame particularly, so central frame 10 can remain on movement 50 inside of shell 3 securely, needn't use the spring of metal or other material.In addition, according to this example, the setting of the setting of supporting leg part 12 and number, outshot 14 and number, also have the shape etc. of central frame 10 to change as requested.
In addition, according to wrist-watch 1, the central frame 10 that comprises the conductive resin compound material contacts with winding arbor 60 at face side recess 13, lower surface 18 in supporting leg part 12 contacts with metal shell bonnet 40, therefore, even the part at last bar handle 62 produces static, can make static flow to the case rear cover 40 of metal by the central frame 10 of conduction, can avoid static to flow to the IC7 or the like of movement 50 inside basically, or too high voltage is applied to the IC7 or the like of movement 50 inside.Therefore, needn't worry that IC7 or like damage or maloperation.
In addition, replace making whole central frame 10 conductions,, only need make the part conduction of central frame 10 as long as central frame 10 provides conductive path between the lower surface 18 of recess 13 and supporting leg part 12.Particularly, in order to eliminate to being directly connected to or, can be made into non-conductive in the zone that comprises these regional movements 50 with respect to the charge generation discharge in central frame 10 zones of each electronic component, wiring pattern or the similar components and parts of movement 50 or the worry of similar behavior.In addition, as required, part or all that makes outshot 14 contacts with the periphery of the opening portion 32 of housing 30, perhaps, comprises that the big zone of outshot 14 can form non-conductive district.The non-conductive district of the non-conductive main part of this formation can less than or greater than current-carrying part or zone, for example, non-conductive zone can occupy most of zone of central frame 10.In all cases, non-conductive zone forms by non-conductive composite resin material, but not the conductive resin compound material is made by the non-conductive millimicro carbon of disperse in resin pipe.In this case, in order to form non-conductive district, usually, use basically and carry out disperse conduction millimicro carbon pipe so that form the identical resin stock of resin stock of conductive path with the conductive resin compound material, conductive region (current-carrying part) and non-conductive zone (non-conductive part or non-conductive main part) undertaken Unitarily molded by so-called double-colored or polychrome injection molding process.
In addition, the rigidity of composite resin material (relatively elastic modulus, the unit of compression deformation be newton/square metre) littler much than metal material such as stainless rigidity, although composite resin material adopts millimicro carbon pipe to carry out disperse and is strengthened by millimicro carbon pipe, therefore, replace separating and (for example form central frame 10 with the main part of movement 50, mainboard 51 or like), as illustrated in Figures 5 and 6, the main part 70 of movement 50 can form to constitute medial support structures by current-carrying part 71 and non-conductive part 72.The other parts of movement 50 can cooperate other parts to be fixed to main part 70 by being screwed directly or indirectly to connect other parts or connect.In this case, current-carrying part 71 general rigid resin materials by conduction form, and wherein the electroconductive resin material is made by the conduction of disperse in resin stock millimicro carbon pipe.Non-conductive part 72 is general to be formed by non-conductive rigid resin material, and wherein the nonconductive resin material is made by the non-conductive millimicro carbon of disperse pipe in the resin stock of or identical type identical with the resin stock of current-carrying part 71.Current-carrying part 71 and non-conductive part 72 is by double-colored or the polychrome injection molding process is Unitarily molded.In addition, Fig. 5 in the second embodiment of the present invention shown in Figure 7 with Fig. 1 to the identical or similar member of components and parts embodiment illustrated in fig. 4, part or element have with the first embodiment situation under the identical label of components and parts.
