Embodiment
The preferred embodiments of the present invention are described with reference to the accompanying drawings.The electro-acoustic element connector of this embodiment comprises: one as shown in Fig. 1～9 and Figure 18 covers or is installed in as the Insulated Housing 10 on the electrode part 2 at the periphery place on the electro-acoustic element downside of a cellular phone part; A conductive connecting element 20 that passes this mounting 10 and support by mounting 10, these parts 20 exist pressure to contact with the pair of electrodes 3 that is placed in following electro-acoustic element, and owing to the compacted paired electrode 3 of finishing electro-acoustic element 1 and above circuit board 30 on electrode between conduction.
The example of electro-acoustic element 1 comprises all kinds of loud speakers (comprising receiver) or microphone (as directionless microphone, directional microphone and so on), and it to be configured in Fig. 4 its vibrating membrane downward.This electro-acoustic element 1 has basically just like short cylindrical, the circle button shaped and so on shown in Fig. 1 and Fig. 2, and the part of its neighboring is radially protruded and form an approximate rectangular electrode part 2.Be configured in as being a pair of on the trailing flank of this electrode part 2 of back plate with preset distance rectangular metal plate electrode 3 at interval.
Shown in Fig. 3～5, mounting 10 usefulness predetermined materials are made by injection moulding, extruding, stickup, machine work etc., and can be installed on the peripheral part of electro-acoustic element 1 with dismantling and engage with electrode part 2.As the material of this mounting 10, the multipurpose plastic that can use that thermal impedance is good, dimensionally stable, moldability etc. is good, engineering plastics, various elastomer (as silicone rubber) and so on.Object lesson comprises polypropylene, polyvinyl chloride, polyethylene, ABS resin, Merlon, the Merlon that contains glass fibre, Polyetherimide, polyamide, polyether sulfone, aromatic polyester, liquid crystal polymer.In these materials, from machinability and cost, Merlon is only.
The material that should be noted in the discussion above that mounting 10 is not limited thereto.For example, can use as the elastic resin spare of mentioning later on 21 and the same material of supporting course 23.
But this configuration should not limit the present invention.Be fixed on by two free ends in the electrode part 2 of electro-acoustic element 1 and also can prevent to move, thereby the electrode part 2 that perhaps forms the equipped electro-acoustic element of prism shape at angle by two free ends with mounting 10 also can prevent to move (see Fig. 6 (b) and scheme (c)) mounting 10.
Conductive connection part as shown in Fig. 3,8,9 divide 20 by one can dismantle ground or the elastic resin spare 21 and the Duo Gen fine wire 22 that are fixedly fitted in the pocket-shape hole of mounting 10 form, these many fine wires 22 are embedding point-blank and a preset space length is longitudinally arranged being arranged in many rows along the short transverse of elastic resin spare 21, thereby contact with the pair of electrodes 3 of electro-acoustic element 1.The packet of elastic resin spare 21 for making with the predetermined material of dimensionally stable, it neither can significantly be out of shape owing to gravity, also can distortion plastically after hardening.What secondly, resin piece 21 can have a same shape optionally is bonded in supporting course 23 on its one or both sides.
Can be natural rubber and copolymer rubber such as butadiene-styrene as the material of elastic resin spare 21 and supporting course 23, acrylonitrile-butadiene, acrylonitrile-butadiene-styrene (ABS), styrene-ethylene, ethylene-propylene, ethylene-propylene-diene and synthetic rubber such as chloroprene rubber, silicone rubber, butadiene rubber, isoprene rubber, chloro-sulfonated polyethylene rubber, many sulphur rubbers, butyl rubber, fluorubber, polyurethane rubber, Oppanol, and thermoplastic elastomer (TPE) such as polyester elastomer etc., the vinyl chloride resin of plasticising, vinyl acetate resin, vinyl chloride-vinyl acetate copolymer etc.Wherein, the charge is small and good silicone rubbers such as ageing properties, electrical insulating property, thermal endurance, compression set, machinability are best.
Use with mounting 10 identical materials and be suitable for the integrated of mounting 10 and conductive connecting element 20 most.
As silicone rubber, usually can consider dimethyl-, aminomethyl phenyl-and methyl ethylene-polysiloxanes, thereby mixed the halide polysiloxanes that a kind of filler such as silicon dioxide have suitable rheological properties, with the halide polysiloxanes of slaine sulfuration or curing.
Dispose many fine wires 22, make the every electrode 3 of electro-acoustic element 1 contact with two or more fine wires 22.The reason of doing like this is that if many fine wires 22 contact with the every electrode 3 of electro-acoustic element 1, resistance can alleviate concentrating of stress with regard to stablizing.Every fine wire 22 can be made with gold, silver, billon, copper, aluminium, alusil alloy, brass, phosphor bronze, beryllium-bronze, nickel, Nitinol, copper, tungsten, stainless steel, iron, iron-carbon alloy and so on, perhaps can make with one of these materials that are coated with metal on demand.Wherein, have in mind from the stability of resistance under hot and humid environment and erosion-resisting stability and similar performance, it is best having plated golden fine wire 22.
The diameter of every fine wire 22 should be in the scope of 3～500 μ m, preferably 10～100 μ m.This scope is stipulated, because if these wires are too thin, these can rupture when lining up array.On the contrary, if wire is too thick, just can not reach desired little spacing.Secondly, in the scope of 3～500 μ m, (be preferably in the scope of 10～100 μ m), just can reach easy operation and moldability if stipulate the diameter of every fine wire 22.
In above-mentioned configuration, conduction between electro-acoustic element 1 and the circuit board 30 realizes by following approach: mounting 10 is assembled into the electrode part 2 that covers electro-acoustic element 1, conductive connecting element 20 is assembled into the slotted eye 11 that passes mounting 10 and by its supporting, an end of fine wire 22 is positioned to the electrode 3 of electro-acoustic element 1 contacts, this assembly is packed in the casing of cellular phone etc., the other end of fine wire 22 is positioned to the electrode of circuit board 30 contacts, and depress circuit board 30 at last it is fixed, can realize the conduction between electro-acoustic element 1 and the circuit board 30 thus reliably.
Or, conduction between electro-acoustic element 1 and the circuit board 30 can realize by following approach: conductive connecting element 20 is assembled into the slotted eye 11 that passes mounting 10 and by its supporting, mounting 10 is assembled into the electrode part 2 that covers electro-acoustic element 1, and the fine wire 22 of conductive connecting element 20 is positioned to the electrode 3 of electro-acoustic element 1 contacts.Conductive connecting element 20 is assembled into the slotted eye 11 that passes mounting 10 and reaches an action by its supporting and can manually finish or finish automatically by automatic setup system.Secondly, can also provide mounting 10 and conductive connecting element 20 respectively and integral body formation as illustrated in fig. 10, thereby reduce part count.
In above-mentioned configuration, because not being welding, the electrical connection between electro-acoustic element 1 and the circuit board 30 do not form, so even when needing to repair owing to carrying is improper, also can reuse electro-acoustic element 1, thereby can increase work efficiency significantly etc.Secondly, because replace the spring terminal, so no longer need the predetermined space that is preserved for connecting with fine wire 22.Therefore, can follow the microminiaturization and the light-weighted recent tendency of cellular phone etc.
Because do not connect the impedance unsettled danger that becomes, the fatigue that comes off and produce owing to the gold-plated part that repeats applied load or electrode can not appear, so can guarantee significantly stable connection conduction.And, because do not use coil form spring terminal, so can avoid tired and similar problem effectively.In addition because mounting 10 makes and only cooperates and cover the electrode part 2 of electro-acoustic element 1 rather than cooperate and cover electro-acoustic element 1, so can be significantly less with material with reduce manufacturing cost.
Secondly, Figure 11 represents the second embodiment of the present invention.In this embodiment, conductive connecting element 20 is made of the elastic resin spare 21 and the Duo Gen fine wire 22 of an insulation, this resin piece 21 has approximate half elliptic, be assemblied in removably in the slotted eye 11 of mounting 10, these many fine wires 22 are approximate U-shaped, be arranged in rows on the curved surface of elastic resin spare 21 with predetermined spacing, make these fine wires can compress the electrode of contact electro-acoustic element 1 and the electrode of circuit board 30.Can a selectively bonding unshowned independently rubber layer on the rectilinear upright surface of elastic resin spare 21.
Mounting 10 and conductive connecting element 20 can integrally form rather than form respectively.Elastic resin spare 21 is identical with the material of supporting course 23.Because other parts are same as the previously described embodiments, so no longer narration.
Can expect that the operating effect of second embodiment is identical with first embodiment.Simultaneously, when fine wire 22 was can not be along the short transverse of elastic resin spare 21 embedding point-blank, this configuration was affected significantly.
Secondly, Figure 12 represents the third embodiment of the present invention.In this embodiment, conductive connecting element 20 is block elastic resin spare 21, can be assemblied in removably in the slotted eye 11 of mounting 10.This elastic resin spare 21 is made and is alternately arranged tabular flexible insulating elastomer 25 and conductive elastomer 26, forms a plurality of laminations side by side, and its faying face is parallel to each other.A plurality of layers of the conductive elastomer 26 of elastic resin spare 21 press the electrode of electro-acoustic element 1 and the electrode of circuit board 30.
The hardness of elastic resin spare 21 (with the test method measuring of JIS-K6253 (ISO7619) regulation) is preferably solidified at 50～80 degree, more preferably at 60～80 degree.Connect equably also can be to 2%～10% the time time even this hardness is solidified when compression ratio is significantly little, and can almost completely eliminate and compress the distortion that brings in conduction.Secondly, can obtain a kind of reliable and stable connection status by the little load that acts on the utensil.As a result, can impel the development compactness and the configuration of light weight.
Elastic resin spare 21 is produced by printing or calendering.Preferential employing calendering is because can stably produce.For example, can on pet film, form the film of insulating elastomer 25, and heat and solidify by calendering.Then, on insulating elastomer 25, form the film of conductive elastomer 26 by calendering.The pellicular cascade of Huo Deing comes off from pet film like this, makes these laminations form as a whole to have to form a blocks as a plurality of layers of above-mentioned same orientation., blocks cut into slices, thereby produce elastic resin spare 21 thereafter.
The difference of insulating elastomer 25 and conductive elastomer 26 only is whether add electric conducting material.The material of insulating elastomer 25 and conductive elastomer 26 is identical with the material of elastic resin spare 21 and supporting course 23.As conductive elastomer 26, adding is the amount that 50～800 parts are preferably the electric conducting material of 100～600 parts by weight.Regulation is because if this amount, just can not obtain satisfied resistivity by weight less than 50 parts like this, thereby the connector function that can not obtain to expect.On the contrary, when this measures by weight greater than 800 parts, just can not reach elastomeric function.
As the electric conducting material of conductive elastomer 26, can use carbon compound, graphite, gold, silver, billon, copper, aluminium, aluminium-silicon alloys, brass, phosphor bronze, beryllium-bronze, nickel, Ni-Ti alloy, molybdenum, tungsten, stainless steel, iron, iron-carbon alloy etc.Electric conducting material can have various particulate form, as spherical, ellipse, sheet and other form.As required, this particulate can be a metal particle, also can be the thermoplastic resin particle that scribbles metal, thermosetting resin particulate, silicon dioxide microparticle etc.These particulates can use separately, but also two or more share.From the stable viewpoint of resistivity, preferentially adopt silver-plated or golden particulate.
Mounting 10 and elastic resin spare 21 or mounting 10 and conductive connecting element 20 can wholely form rather than form respectively.Other configuration is identical with previous embodiment, therefore no longer narration.
Can expect that equally operating effect in the above-described embodiments is identical with the embodiment that narrates previously.Simultaneously, because do not need to arrange many fine wires 22,, can reduce part count significantly and improve processing characteristics so obviously can expect.
Secondly, Figure 13 to Figure 16 (a) and (b) the expression fourth embodiment of the present invention.In this embodiment, the shape of mounting 10 is made curved configuration with approximate L shaped cross section and bonded or gluing and cover electrode 2 on electro-acoustic element 1 downside.Conductive connecting element 20 comprises the many conductive filaments 27 that are configured in such a way between electro-acoustic element 1 and the circuit board 30, make these conductive filaments tilt with respect to direction vertical or that enter, flexible first insulating elastomer 28 partly be bonded on the back side of these many conductive filaments 27 and with electrode 2 Elastic Contact of electro-acoustic element 1, and flexible second insulating elastomer 28A partly is bonded on the front of these many conductive filaments 27 and the electrode of Elastic Contact circuit board 30.First and second insulating elastomers 28 and 28A are configured to from the approximate center P of the length of conductive filament 27 and still are configured to the point symmetry that becomes to be similar to respect to this approximate center P, make its cross section form an approximate X-shaped shape, and first insulating elastomer 28 makes its end be bonded in and be combined on the mounting 10 by this way, so that the exposure of conductive filament 27 and first or second insulating elastomer 28,28A limits the space 29 that the contact area of a triangular-section reduces.
Many conductive filaments 27 are arranged side by side with 0.02mm or bigger preset space length, as shown in Figure 13 and Figure 15 (a) and 15 (b).These many conductive filaments 27 extend point-blank with predetermined inclination angle.This inclination angle is preferably 30～60 degree, more preferably is 45 degree.If the inclination angle is less than 30 degree, it is too low that the pressure during conduction reduces influence, thereby conductive filament 27 is easily deformable.Otherwise when the inclination angle was spent greater than 60, the height dimension of electro-acoustic element connector was too little, thereby can not absorb the variation that the pressure of electro-acoustic element connector brings.
Every conductive filament 27 usefulness gold, billon, copper, aluminium, alusil alloy, brass, phosphor bronze, beryllium-bronze, nickel, Nitinol, molybdenum, tungsten, stainless steel, iron, iron-carbon alloy etc. are made, and having long slab shape, band shape or wire, its surface is coated with gold, billon etc. when needing.In order to improve the viscosity of conductive filament, use the grease on solvent flush away conductive filament 27 surfaces when needing to first and second insulating elastomers 28 and 28A.Secondly, when first and second insulating elastomers 28 and 28A are silicone rubber,, can apply the gluing assistant (as silane coupler) that has silicone rubber when needing in order to tackify.
The thickness of every conductive filament 27 is 0.01～0.5mm, is preferably 0.02～0.5mm.If thickness is less than 0.01mm, this material lacks the intensity as the silk material, and lack useful life when as product, and hauling ability is poor during fabrication.Otherwise when thickness during greater than 0.5mm, the rigidity of material is too big and can not adapt to connected load, and is difficult to finish processing such as etching, laser forming, punching press.
Approximate center P in conductive filament 27 length indicates near half mid point of this length.
First and second insulating elastomers 28 and 28A make with flexible non-foam material such as silicone rubber, polybutadiene rubber, natural rubber, polyisoprene rubber, poly-ammonia ketone rubber, chloroprene rubber, ECD or the foamed material of one of them, and each has the thickness that extends along the internal direction of Figure 12, and each forms a bending with approximate L shaped, approximate V-arrangement or approximate opening V-arrangement cross section.These elastomers are configured to overlap each other and conductive filament 27 are clipped in wherein when making.Because the material of first and second insulating elastomers 28 and 28A has the same form of above-mentioned material silicone, so their electric insulation, heat-resisting, chemical resistance all are good, heat-resisting and compression set is best.
The hardness range of first and second insulating elastomers 28 and 28A is 10 °～70 ° H of rubber hardness, preferably 30 °～60 ° H.Surpass this scope, rubber hardness needs high contact pressure too greatly.When rubber hardness during less than 30 ° of H, after shaping, produce stickiness feeling (especially to silicone rubber), thereby carrying inconvenience.Otherwise, if rubber hardness greater than 60 ° of H, just requires greater than essential high contact pressure.
Mounting 10 and conductive connecting element 20 can wholely form rather than form respectively.Other parts are identical with previous embodiment, therefore no longer narration.
In above-mentioned configuration, mounting 10 usefulness glue etc. stick to or are fixed on by assembling on the electrode part 2 of electro-acoustic element 1, and conductive connecting element 20 is placed in and is clipped between electro-acoustic element 1 and the circuit board 30, and circuit board 30 is depressed towards electro-acoustic element 1.As a result, first and second insulating elastomers 28 and the 28A that play elastic supporting piece shrink, thereby form reliably between the electrode of the electrode of electro-acoustic element 1 and circuit board 30 by many conductive filaments 27 and to connect, and realize conduction.
In this embodiment simultaneously, can expect influences with the previous embodiment identical operations.Secondly, be the space 29 that contact area reduces because above or below first and second insulating elastomers 28 and 28A, form hollow parts, so can reduce the contact area of contact-making surface as far as possible.Because connection pressure is discharged along the incline direction of many conductive filaments 27, so can alleviate connection pressure.As a result, can reduce connected load significantly with a simple configuration.
Because many conductive filaments 27 tilt, thus the distortion of the conductive filament 27 that causes by compression can be prevented, and thereby improve the performance of repeated compression significantly.In particular, can affirm, after 100 repeated compression, can obtain stable resistance.Because can come the control connection load by the shape and the hardness that change first and second elastomers 28 and 28A, not need to change significantly the width and the height of product so can set a desired load value.
Though the foregoing description is wherein a plurality of fine wires 22 to be arranged in two row and to be embedded in configuration in the elastic resin spare 21 with reference to a kind of, also the fine wire 22 of a single file can be embedded in the elastic resin spare 21, maybe can arrange triplex row or multirow more.In the 4th embodiment, though mounting 10 is made bending, make it have approximate L shaped cross section, the present invention should be not limited thereto.For example, mounting 10 can be made approximate tabular cross section, approximate C tee section, approximate J-shaped cross section or other shape.Also having, can be bonding and be combined on the mounting 10 in the end of the second non-wavy elastomer 28A.
Secondly, Figure 17 represents the fifth embodiment of the present invention.In this embodiment, conductive connecting element 20 usefulness pair of conductive rubber pin 40 constitute, and this is to conductive rubber pin 40 preset distance that is configured to be separated by, and pass mounting 10 and by its supporting, the flexible conductive elastomer 26 of each conductive rubber pin 40 usefulness is made.This top and bottom to the exposure of conductive rubber pin 40 is suitable for pressing the electrode of electro-acoustic element 1 and the electrode of circuit board 30.
Each conductive rubber pin 40 can be made cylindrical shown in the figure, but should be not limited thereto.For example, the shape of pin can be made elliptical cylinder-shape, prismatic, triangle or polygon cylindrical.Except two pins as shown in the figure, the pin of a plurality of numbers also can be set, 3,4,5,6,8 or the like.Other parts are identical with previous embodiment, therefore no longer narration.
In this embodiment simultaneously, obviously can expect and previous embodiment identical operations effect.Also have, because can omit elastic resin spare 21 and insulating elastomer 25, so can expect consumingly and reduce part count and simplify configuration.
Industrial use
As describing before this, even being electro-acoustic element, benefit of the present invention need repairing also can Be reused, and cellular phone can be developed into compactness and the configuration of light weight. Can also disappear The unstability of the contact resistance of following except the vibration of electro-acoustic element and the fatigue of attaching parts and not Stable connection etc.
