Description

CONNECTOR FOR ELECTRO-ACOUSTIC COMPONENT AND CONNECTION STRUCTURE THEREOF}

The present invention provides a connector for an electro-acoustic component for electrically conducting an electric acoustic component composed of a microphone, a speaker, and the like used in a cellular phone, a portable terminal (handy personal, a PDA, etc.) and an electrical joint composed of a circuit board, and the connection structure thereof. It is about.

In the case of using an electroacoustic component as the voice communication or confirmation sound generating means of a cellular phone, the electroacoustic component and the circuit board are electrically connected. However, as a means of the conduction, soldering by a pin terminal or a lead wire is conventionally performed. ) Is used. Also, in recent years, as the spread of mobile phones and the like has been promoted to increase the variety of products and shorten the life of the products, mounting methods of electro-acoustic components have also been reconsidered. In view of the above, a method of using an inexpensive spring terminal has been studied.

As mentioned above, conventionally, when electrically conducting between an electroacoustic component and the electrode of a circuit board, the method of using the soldering by a pin terminal, a lead wire, and a cheap spring terminal is used, but these are disclosed below. There is a problem.

First, in the case of the solder directly connected to the circuit board, there is a problem that efficiency cannot be achieved because the electro-acoustic components cannot be used again when repair is required due to work error or the like.

In addition, when using a spring terminal, it is necessary to secure a certain amount of space for connection, and therefore it is difficult to cope with the recent miniaturization and weight reduction of a mobile telephone. In addition, the electroacoustic component forcibly generates vibrations around the structure, but when vibration occurs, the connection resistance of the spring terminal becomes unstable. In addition, since the spring terminal is repeatedly loaded, there is little risk of fatigue (also referred to as wear-out) or wear of the gold-plated portion of the electrode. As a result, the resistance value rises to ensure stable connection conduction. It becomes impossible.

In order to solve this problem, a technique using a coil type spring terminal has been proposed. According to this technique, the above problem can be solved to some extent, but it is difficult to eliminate fatigue of the spring terminal and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and it is possible to reuse electroacoustic components even when repair is required, and to cope with miniaturization and weight reduction of electrical joints, and also to destabilize the connection resistance accompanying vibration, fatigue of the connector, and unstable. An object of the present invention is to provide a connector for an electroacoustic component and a connecting structure thereof capable of eliminating a connection or the like.

EMBODIMENT OF THE INVENTION Hereinafter, if preferred embodiment of this invention is described with reference to drawings, the electroacoustic component connector in this embodiment is an electroacoustic component which comprises a mobile telephone as shown to FIG. 1 thru | or FIG. An insulating holder 10 which is covered or bonded to the electrode portion 2 at the outer periphery of the back surface of the component 1, and a pair of electrodes of the electroacoustic component 1 below which is penetrated and supported by the holder 10; A conductive connector 20 in compression contact with 3) is provided, and the pair of electrodes 3 of the electroacoustic component 1 and the electrodes of the upper circuit board 30 are compressed to conduct.

The electroacoustic component 1 is made of various speakers (including a receiver), microphones (for example, omnidirectional microphones, directional microphones, and the like) and the like, and is disposed in a state of facing the vibration membrane in FIG. 4 downward. As shown in Figs. 1 and 2, the electroacoustic component 1 is basically formed in a low circumferential shape or a round button shape or the like, and a part of the outer circumferential portion protrudes into a substantially rectangular shape in the radial direction to form an electrode portion ( 2) is formed, and a pair of electrodes 3 made of a rectangular metal plate is provided side by side at a predetermined interval on the back plate, which is the rear surface of the electrode portion 2.

The holder 10 is formed by injection molding, extrusion molding, pasting, cutting, etc. using a predetermined material, and as shown in FIGS. 3 to 5, an electrode which is an outer peripheral part of the electroacoustic component 1. The part 2 is detachably fixed. Examples of the material of the holder 10 include general-purpose plastics, engineering plastics excellent in heat resistance, dimensional stability, and moldability, and various elastomers (for example, silicone rubber). Specifically, polypropylene, vinyl chloride, polyethylene, ABS resin, polycarbonate, glass fiber-containing polycarbonate, polyetherimide, polyamide, polyethersulfone, aromatic polyester, liquid crystal polymer and the like are used. Among these materials, polycarbonate is most suitable from the viewpoint of workability and cost.

In addition, the material of the holder 10 is not limited to these at all. For example, the same material as that of the elastic resin body 21 and the support layer 23 described later can be used.

As shown in Figs. 3 and 5 to 7, the holder 10 is basically formed in a substantially convex shape in a plane, and is bent in a cross-section in a substantially U-shape or in a roughly cylindrical shape, so that the pocket for a conductive connector is formed. Holes 11 are drilled into elongated, approximately oval or rectangular shapes. At both free ends extending downward of the holder 10, the fall prevention rings 12 are each bent inwardly (see FIG. 6A) in consideration of assemblability, cost, and the like, so that the fall prevention rings 12 are Detachable coupling to the electrode portion 2 of the electroacoustic component 1 effectively regulates the dropping of the conductive connector 20.

However, the present invention is not limited to any of these configurations, and the free ends of the holder 10 are coupled to the electrode portions 2 of the electroacoustic components 1 to prevent dropout, or both free ends of the holder 10 are connected to each other. It may be formed in a shape so as to be coupled to the electrode portion 2 of the electroacoustic component 1 to regulate the dropout (see FIGS. 6B and 6C).

3, 8, and 9, the conductive connector 20 is formed of an insulating elastic resin body 21 detachably or fixedly coupled to the pocket hole 11 of the holder 10. A plurality of metals which are linearly embedded in the height direction of the elastic resin body 21 and are arranged side by side in a plurality of rows in the longitudinal direction at a predetermined pitch, and are in contact with the pair of electrodes 3 of the electroacoustic component 1. It consists of the thin wires 22. The elastic resin body 21 is formed into a block body using a predetermined material that is not deformed remarkably due to gravity or plastically deformed after curing, and has a support layer having the same shape on both surfaces or one surface ( 23) is optionally bonded.

As the material of the elastic resin body 21 or the support layer 23, natural rubber, butadiene-styrene, acrylonitrile-butadiene, acrylonitrile-butadiene-styrene, styrene-ethylene, ethylene-propylene, ethylene-propylene-diene In addition to each copolymer rubber, chloroprene rubber, silicone rubber, butadiene rubber, isoprene rubber, chlorosulfonated polyethylene rubber, polysulfide rubber, butyl rubber, fluorine rubber, urethane rubber, polyisobutylene rubber, etc. Thermoplastic elastomers such as polyester elastomers, plasticized vinyl chloride resins, vinyl acetate resins, and vinyl chloride vinyl acetate copolymer resins. Among these, an inexpensive silicone rubber excellent in aging characteristics, electrical insulation, heat resistance, compression set and workability is optimal.

Moreover, when the same material as the holder 10 is used, it is optimal for integration of the holder 10 and the electrically conductive connector 20. Moreover, as shown in FIG.

As silicone rubbers, polysiloxanes such as dimethyl-, methylphenyl- and methylvinyl- and fillers such as silica are usually mixed to vulcanize or harden with halogenated polysiloxanes or metal salts to which proper rheology is given. Halogenated polysiloxanes;

The plurality of fine metal wires 22 are arranged such that two or more fine metal wires 22 contact each electrode 3 of the electroacoustic component 1. This is because when the plurality of fine metal wires 22 are in contact with each electrode 3 of the electroacoustic component 1, the resistance value is stabilized, and furthermore, stress relaxation can be expected. Each fine metal wire 22 is made of gold, silver, gold alloy, copper, aluminum, aluminum-silicon alloy, brass, phosphor bronze, beryllium copper, nickel, nickel-titanium alloy, molybdenum, tungsten, stainless steel, iron, iron-carbon Materials, such as an alloy, are used, or metal plating is given to these materials as needed. Among these, the metal fine wire 22 to which gold plating was applied is preferable from a viewpoint of stability, such as corrosion value in the environment, such as resistance value and high temperature, high humidity, and the like.

In addition, the diameter of each metal fine wire 22 is 3-500 micrometers, Preferably it is the range of 10-100 micrometers. This is because if too thin, there is a risk of disconnection at the time of arrangement, and if too thick, a small pitch is not obtained. It is because moldability and handling become easy when the diameter of each metal fine wire 22 is made into 3 to 500 micrometers, Preferably it is 10 to 100 micrometers.

In the above configuration, in the case where the electroacoustic component 1 and the circuit board 30 are connected to each other, the holder 10 is bonded to the electrode portion 2 of the electroacoustic component 1 and the holder 10 is coated. The conductive connector 20 is supported through the pocket hole 11 of the battery, and one end of the fine metal wire 22 is brought into contact with the electrode 3 of the electroacoustic component 1, and is assembled in a case such as a mobile phone. When the electrode of the circuit board 30 is brought into contact with the other end of the fine metal wire 22 to press-press and fix the circuit board 30, the electroacoustic component 1 and the circuit board 30 can be reliably connected. (See Figure 18).

In the case where the electroacoustic component 1 and the circuit board 30 are connected to each other, the conductive connector 20 is allowed to penetrate through the pocket hole 11 of the holder 10, and the electrode portion of the electroacoustic component 1 ( The holder 10 may be bonded to and coated with 2) so that the fine metal wire 22 of the conductive connector 20 is brought into contact with the electrode 3 of the electroacoustic component 1. In addition, as for the method of penetrating and supporting the conductive connector 20 in the pocket hole 11 of the holder 10, manual work may be sufficient and automatic work by an automatic installation apparatus may be sufficient. In addition, it is also possible to reduce the number of parts by integrally molding as shown in FIG. 10 without separately making the holder 10 and the conductive connector 20 separate.

According to the above configuration, since the electroacoustic component 1 and the circuit board 30 are not electrically connected by soldering, the electroacoustic component 1 can be used again even when repair is required due to, for example, a work mistake. As a result, remarkable efficiency of work and the like can be achieved. In addition, since the thin metal fine wire 22 is used without using the spring terminal, there is no need to secure a predetermined space for connection. Therefore, it is possible to sufficiently cope with the recent miniaturization and weight reduction of the cellular phone.

In addition, since there is no fear of unstable connection resistance, fatigue due to repetitive load, or peeling of the gold plating of the electrode, very stable connection conduction can be ensured. In addition, since the coil type spring terminal is not used, fatigue and the like can be effectively eliminated. In addition, since the holder 10 does not bind and house the electroacoustic component 1 and covers only the electrode portion 2 of the electroacoustic component 1, it is possible to considerably reduce the material and reduce the manufacturing cost. .

Next, FIG. 11 shows the second embodiment of the present invention. In this case, the semi-coin type that detachably couples the conductive connector 20 to the pocket hole 11 of the holder 10 is shown. Approximately U, which is arranged in a row at a predetermined pitch on the insulating elastic resin body 21 and the curved surface of the elastic resin body 21 and is in compression contact with the electrodes of the electroacoustic component 1 and the circuit board 30. It consists of the several fine metal wires 22 which showed the magnetic shape, and makes it adhere | attach the separate rubber layer not shown to the linear elevation of the elastic resin body 21 selectively.

The holder 10 and the conductive connector 20 can be formed integrally without being separated. The material of the elastic resin body 21 is the same as that of the elastic resin body 21 and the support layer 23. Other parts are the same as in the above-described embodiment, so description thereof is omitted.

Also in this embodiment, the effect similar to the said embodiment can be expected, Moreover, it is very effective when the metal fine wire 22 cannot be embedded linearly in the height direction of the elastic resin body 21, etc.

Next, FIG. 12 shows 3rd Embodiment of this invention, In this case, the block-shaped elastic resin body which detachably couples the electrically conductive connector 20 to the pocket hole 11 of the holder 10 (FIG. 21, the elastic resin body 21 is laminated in alternating and multiple layers so that the joining surfaces thereof are parallel to each other, and the elastic insulating elastomer 25 having a thin plate shape is parallel to each other. By arrange | positioning, the some electroconductive elastomer 26 of this elastic resin body 21 is made to make compression contact with the electrode of the electroacoustic component 1 and the circuit board 30. As shown in FIG.

The elastic resin body 21 is set to 50-80 degrees, preferably 60-80 degrees of hardness (measured by the test method of JIS-K6253 (ISO7619)]. By the hardness setting, even when the compression ratio is 2 to 10%, even when a value is extremely small, uniform connection is possible, and buckling caused by compression can be almost eliminated. In addition, a reliable and stable connection state is obtained, and the load on the apparatus is reduced, whereby miniaturization and weight reduction can be expected.

Although the elastic resin body 21 is manufactured by methods, such as a printing method and a calendering method, it is preferable that it is manufactured by the calender method which can be produced stably. For example, a thin film of insulating elastomer 25 is formed on a polyethylene terephthalate film by calender, and heat-cured, and a conductive elastomer 26 is formed of thin film by calender on the insulating elastomer 25. At the same time, the obtained laminated thin film is peeled from the polyethylene terephthalate film, and a plurality of the laminated thin films are laminated in the same order to form a block body. After that, the elastic resin body 21 can be manufactured by slicing and cutting the laminated thin film.

The insulating elastomer 25 and the conductive elastomer 26 differ only depending on whether or not the conductive material is added. The materials of these insulating elastomers 25 and conductive elastomers 26 are the same as those of the elastic resin body 21 and the support layer 23. The conductive elastomer 26 is added with 50 to 800 parts by weight of conductive material, preferably 100 to 600 parts by weight. This is because a sufficient resistance value cannot be obtained at less than 50 parts by weight, and a function as a connector cannot be expected. On the contrary, when more than 800 weight part, the function as an elastic body will produce a defect.

Examples of the conductive material of the conductive elastomer 26 include carbon-based, graphite, gold, silver, gold alloys, copper, aluminum, aluminum-silicon alloys, brass, phosphor bronze, beryllium copper, nickel, nickel-titanium alloys, molybdenum, tungsten, Materials such as stainless steel, iron and iron-carbon alloys are used. The particle shape of the conductive material may be various shapes such as spherical shape, elliptical shape, and debris. As the particles, metal plating may be performed on the particles of the metal material, the thermoplastic resin particles, the thermosetting resin particles, the silica particles, or the like as necessary. Although these may be used singly or in mixture of two or more thereof, it is preferable to perform silver or gold plating from the viewpoint of stability of resistance value.

It is also possible to integrally mold the holder 10 and the elastic resin body 21, that is, the holder 10 and the conductive connector 20 separately. Other parts are the same as in the above-described embodiment, so description thereof is omitted.

Also in this embodiment, the same effect as that of the said embodiment can be expected. Moreover, since it is not necessary to arrange the several fine metal wires 22 in parallel, it can expect largely the reduction of the number of components and the improvement of workability. Obvious.

Next, FIGS. 13 to 16A and 16B show a fourth embodiment of the present invention. In this case, the holder 10 is overlapped with the back electrode portion 2 of the electro-acoustic component 1 or The coating is bent to form an approximately L-shaped cross section. The conductive connector 20 is interposed between the electroacoustic component 1 and the electrodes of the circuit board 30, and is provided with a plurality of conductive filigrees 27 inclined with respect to their vertical access direction, and the plurality of conductive connectors 20. On the surface of the first conductive elastomer 28 and the plurality of conductive preforms 27, which are elastically partially adhered to the back surface of the conductive preforms 27 and elastically contact the electrodes 3 of the electroacoustic component 1, respectively. The first insulating part 28A is formed of an elastic second insulating elastomer 28A that is partially bonded and elastically contacts the electrode of the circuit board 30, and is based on a substantially central portion P in the longitudinal direction of the conductive wire material 27. The second insulating elastomers 28 and 28A are arranged in a substantially X-shaped cross section by shifting them approximately point-symmetrically, and at the same time between the exposed surface of the conductive filigree 27 and the first and second insulating elastomers 28 and 28A. The contact area reduction spaces 29 of the triangular cross section are respectively formed. Thus, the end portion of the first insulating elastomer 28 is adhered to the holder 10 so as to be bonded.

As shown in FIGS. 13-15A and 15B, the some electroconductive lumber 27 is arrange | positioned by the transverse line at the predetermined pitch of 0.02 mm or more, for example. The plurality of conductive filigrees 27 extend linearly at a predetermined inclination angle, but the inclination angle is in the range of 30 ° to 60 °, preferably 45 °. This is because, when the inclination angle is less than 30 °, the pressure reducing effect at the time of conduction is low, and buckling is likely to occur in the conductive filigree material 27. On the contrary, when it exceeds 60 degrees, the height dimension of the connector for electroacoustic components becomes low, and it becomes impossible to absorb the displacement by compression of the connector for electroacoustic components.

Each conductive precursor 27 is made of gold, gold alloy, copper, aluminum, aluminum-silicon alloy, brass, phosphor bronze, beryllium copper, nickel, nickel-titanium alloy, molybdenum, tungsten, stainless steel, iron, iron-carbon alloy It is formed in elongate plate shape, strip | belt shape, and ancestry using materials, such as these, and plating of gold, a gold alloy, etc. is performed on the surface as needed. The surface of the conductive filigree material 27 is degreased with a solvent as needed in order to improve adhesion with the first and second insulating elastomers 28 and 28A. In addition, when the 1st and 2nd insulating elastomers 28 and 28A consist of silicone rubber, in order to improve adhesiveness, the adhesion | attachment adjuvant with silicone rubber (for example, a silane coupling agent) is apply | coated as needed.

As thickness of each electrically conductive linear material 27, the range of 0.01-0.5 mm, Preferably 0.02-0.5 mm is good. In the case of less than 0.01 mm, this causes a defect in the strength of the material itself, weak durability at the time of use as a product, and further worsens the handleability during molding. On the contrary, when it exceeds 0.5 mm, the rigidity of the material is too high, and the connection load is difficult to be suppressed, for example, processing of etching, laser, stamping press, etc. becomes difficult.

In addition, the substantially center portion P in the longitudinal direction of the conductive linear material 27 refers to a half point of the length of the conductive linear material 27 or the vicinity thereof.

The first and second insulating elastomers 28 and 28A include elastic silicone rubber, polybutadiene rubber, natural rubber, polyisoprene rubber, urethane rubber, chloroprene rubber, polyester rubber, styrene-butadiene copolymer rubber, and epi Non-foamed materials such as chlorohydrin rubber and the like, and are bent and formed into approximately L-shaped, approximately V-shaped, approximately <-shaped cross-sections, and the like extending in the inward direction of FIG. Part (27) is sandwiched with some overlap. As a material of the 1st and 2nd insulating elastomers 28 and 28A which have such a same shape, the use of the silicone rubber excellent in electrical insulation, heat resistance, chemical-resistance, heat resistance, and compression set is optimal among the said materials.

As hardness of the 1st and 2nd insulating elastomers 28 and 28A, the range of rubber hardness of 10 degrees-70 degrees H, Preferably rubber hardness of 30 degrees-60 degrees H is preferable. This is because the rubber hardness becomes high and the compression contact becomes high when it deviates from the related range. Moreover, when rubber hardness is less than 30 degrees H, since the adhesiveness peculiar to silicone rubber arises on the surface after shaping | molding, it becomes difficult to handle. In contrast, when the rubber hardness exceeds 60 ° H, the compression contact becomes higher than necessary.

In addition, the holder 10 and the conductive connector 20 can be integrally molded instead of separately. Other parts are the same as in the above-described embodiment, so description thereof is omitted.

In the above configuration, the holder 10 is adhered or fixed to the electrode portion 2 of the electroacoustic component 1 with an adhesive or the like, so that the conductive connector 20 is connected to the electroacoustic component 1 and the circuit board 30. Positionally sandwich and press-press the circuit board 30 toward the electroacoustic component 1, the first and second insulating elastomers 28 and 28A functioning as elastic supports are compressed, respectively. The electrode of 1), the electrode of the circuit board 30, and the some electrically conductive wired material 27 contact and conduct reliably.

Also in this embodiment, the same effect as that of the said embodiment can be expected, Furthermore, between the upper part and the lower part of the 1st and 2nd insulating elastomers 28 and 28A, the contact area reduction space 29 which is recessed part, respectively is provided. Since it forms, the contact area of a connection surface can be reduced. Further, since the connection pressure is relaxed in the inclined direction of the plurality of conductive stiffeners 27, the connection pressure is relaxed, and as a result, the connection load can be greatly reduced with a simple configuration.

In addition, since the plurality of conductive filigrees 27 are inclined, the buckling of the conductive filigrees 27 due to the compression can be prevented and the repetitive compressibility can be remarkably improved. Specifically, it was confirmed that stable conduction resistance was obtained even after 100 repeated compressions. In addition, by changing the shape and hardness of the first and second insulating elastomers 28 and 28A, the connection load can be controlled, so that the load can be set to an arbitrary value even if the width or height dimension of the product is not significantly changed. There is a number.

In addition, in the above embodiment, the plurality of fine metal wires 22 are embedded in the elastic resin body 21 in two rows, but the fine metal wires 22 may be embedded in the elastic resin body 21 in a line. It may be arranged in three or more rows. In addition, although the holder 10 was bent and formed in about L-shaped cross section in 4th Embodiment, it is not limited to this at all. For example, the holder 10 can be formed into a substantially plate-shaped cross section, an approximately C-shaped cross section, an approximately J-shaped cross section, or the like. In addition, the end portion of the second insulating elastomer 28A may be bonded to the holder 10 for connection.

Next, FIG. 17 shows a fifth embodiment of the present invention. In this case, the pair of conductive rubber pins 40 are supported by penetrating the conductive connector 20 by arranging the holder 10 at predetermined intervals. Each conductive rubber pin 40 is formed by using an elastic conductive elastomer 26, and both upper and lower ends of the pair of conductive rubber pins 40 are exposed to the electroacoustic component 1 and the circuit board 30. Is in compression contact with the electrode.

Each conductive rubber pin 40 has a good columnar shape as shown in the figure, but is not limited thereto, and may be, for example, an ellipse column, a column, a triangle, a polygonal column, or the like. In addition, instead of two as shown in the figure, the number may increase to three, four, five, six, eight, or the like. Other parts are the same as in the above embodiment, and thus description thereof is omitted.

Also in this embodiment, it is clear that the same effect as that of the said embodiment can be expected. In addition, since the elastic resin body 21, the insulating elastomer 25, etc. can be abbreviate | omitted, the reduction of the number of components and the simplification of a structure can be expected largely.

As mentioned above, according to this invention, even if a repair is needed, an electroacoustic component can be used again, Furthermore, there exists an effect that it can respond effectively to the miniaturization and weight reduction of a mobile telephone. In addition, the destabilization of the connection resistance caused by the vibration of the electroacoustic component, fatigue of the connector, or unstable connection can be solved.
