Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 9 and FIG. 18, an electroacoustic component connector according to the present embodiment An insulative holder 10 covered or fitted to the electrode portion 2 on the outer periphery of the back surface of the component 1, and a conductive material that is supported by the holder 10 and pressed against the pair of electrodes 3 of the lower electroacoustic component 1. A connector 20 is provided, and the pair of electrodes 3 of the electroacoustic component 1 and the electrodes of the upper circuit board 30 are made conductive by being compressed. The electroacoustic component 1 is composed of various kinds of speakers (including a receiver) and microphones (for example, omnidirectional microphones and directional microphones), and is arranged with the diaphragm facing downward in FIG. . As shown in FIGS. 1 and 2, the electroacoustic component 1 is basically formed in a low columnar shape or a round button shape, and a part of the outer peripheral portion is formed to protrude in a substantially rectangular shape in the radial direction. The electrode section 2 is formed, and a pair of electrodes 3 made of a rectangular metal plate are arranged side by side at a predetermined interval on a back plate of the electrode section 2.

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

The material of the holder 10 is not limited to these. For example, the same material as the elastic resin body 21 and the support layer 23 described later can be used. As shown in FIG. 3, FIG. 5 to FIG. 7, the holder 10 is basically bent and formed into a substantially convex shape in a plane, a substantially U-shaped cross section, or a substantially rectangular cylindrical shape, and a pocket hole 1 for a conductive connector. 1 is perforated in an elongated generally oval or rectangular shape. At the two free ends extending below the holder 10, fall-off preventing claws 12 are formed inwardly inwardly (see FIG. 6 (a)) in consideration of ease of installation and cost. The claw 12 is detachably engaged with the electrode portion 2 of the electroacoustic component 1, thereby effectively preventing the conductive connector 20 from falling off.

However, the present invention is not limited to such a configuration. The two free ends of the holder 10 are fitted to the electrode portions 2 of the electroacoustic component 1 to prevent the holder 10 from falling off. The portion may be formed in a rectangular cylindrical shape, and may be fitted to the electrode portion 2 of the electroacoustic component 1 so as to restrict the falling off (see FIGS. 6 (b) and 6 (c)).

As shown in FIGS. 3, 8, and 9, the conductive connector 20 has a pocket hole in the holder 10.

11: an insulating elastic resin body 21 that is detachably or fixedly fitted to 1; and is buried linearly in the height direction of the elastic resin body 21 and is arranged in a plurality of rows in a longitudinal direction at a predetermined pitch. And a plurality of thin metal wires 22 that are arranged and contact the pair of electrodes 3 of the electroacoustic component 1. The elastic resin body 21 is formed in a block using a predetermined shape-stable material that does not significantly deform under its own weight or plastically deform after curing, and has a support layer 2 having the same shape on both sides or one side. 3 is selectively glued. Materials for the elastic resin body 21 and the support layer 23 include natural rubber, butadiene * styrene, acrylonitrile / butadiene, acrylonitrile / butadiene / styrene, styrene / ethylene, ethylene / propylene, ethylene / propylene / gene, etc. Other synthetic rubbers such as copolymer rubber, chloroprene rubber, silicone rubber, butadiene rubber, isoprene rubber, chlorosulfonated polyethylene rubber, polysulfide rubber, butyl rubber, fluoro rubber, urethane rubber, polyisobutylene rubber, and polyester elastomer And the like, such as thermoplastic elastomers, plasticized vinyl chloride resins, vinyl acetate resins, and vinyl chloride-pinyl acetate copolymer resins. Of these, inexpensive silicone rubber with excellent aging characteristics, electrical insulation, heat resistance, compression set, workability, etc., is most suitable.

If the same material as the holder 10 is used, the holder 10 and the conductive connector 20 are optimally integrated.

As silicone rubbers, there are usually polysiloxanes such as dimethyl-, methylphenyl, methylvinyl, etc., and halogenated polysiloxanes which are blended with a filler such as silica to give appropriate rheological properties. And halogenated polysiloxanes that are vulcanized or hardened with metal salts.

The plurality of thin metal wires 22 are arranged so that two or more thin metal wires 22 contact each electrode 3 of the electroacoustic component 1. This is because if a plurality of metal wires 22 are brought into contact with each electrode 3 of the electroacoustic component 1, the resistance value can be stabilized and the stress concentration can be reduced. Each metal wire 22 is made of gold, silver, gold alloy, copper, aluminum, aluminum aluminum alloy, brass, phosphor bronze, beryllium copper, nickel, nickel-titanium alloy, molybdenum, tungsten, stainless steel, iron, iron Materials such as carbon alloys are used, and these materials are subjected to metal plating as needed. Among them, the fine metal wire 22 provided with a gold-based plating is preferable from the viewpoint of the resistance value and the stability such as corrosion in an environment such as high temperature and high humidity.

Further, the diameter of each metal wire 22 is 3 to 500 m, preferably 10 to 100 m. m range. This is because if it is too thin, there is a risk of disconnection during arrangement, and if it is too thick, a small pitch cannot be obtained. Further, when the diameter of each thin metal wire 22 is in the range of 3 to 500, preferably 10 to 100, formability and handling are facilitated.

In the above configuration, when the electroacoustic component 1 and the circuit board 30 are electrically connected, the electrode 10 of the electroacoustic component 1 is fitted and covered with the holder 10, and the holder 10 is inserted into the pocket hole 11. The conductive connector 20 is penetrated and supported, and one end of the thin metal wire 22 is brought into contact with the electrode 3 of the electroacoustic component 1 and incorporated into a case of a mobile phone or the like, and a circuit is mounted on the other end of the thin metal wire 22. If the electrodes of the board 30 are brought into contact with each other and the circuit board 30 is fixed under pressing pressure, the electroacoustic component 1 and the circuit board 30 can be reliably conducted (see FIG. 18).

When the electroacoustic component 1 and the circuit board 30 are electrically connected to each other, the conductive connector 20 is supported through the pocket hole 11 of the holder 10, and the holder 10 is connected to the electrode portion 2 of the electroacoustic component 1. The thin metal wire 22 of the conductive connector 20 may be brought into contact with the electrode 3 of the electroacoustic component 1 by fitting and covering. The method of allowing the conductive connector 20 to penetrate and support the pocket hole 11 of the holder 10 may be manual work or automatic work by an automatic mounting device. Further, it is possible to reduce the number of parts by integrally forming the holder 10 and the conductive connector 20 as shown in FIG. 10 instead of separately.

According to the above configuration, the electroacoustic component 1 and the circuit board 30 are not electrically connected to each other by soldering. Therefore, even if repair is required due to a work error or the like, the electroacoustic component 1 is used again. As a result, the efficiency of work and the like can be significantly improved. In addition, since a thin metal wire 22 is used instead of using a panel terminal, there is no need to secure a predetermined space for connection. Therefore, it is possible to sufficiently cope with the recent reduction in size and weight of mobile phones and the like.

In addition, there is no danger of unstable connection resistance, fatigue due to repeated loading, or peeling of the gold plated portion of the electrode. Can be. Furthermore, since coil-type panel terminals are not used, fatigue can be effectively eliminated. Furthermore, since the holder 10 does not fit and store the electro-acoustic component 1 but fits and covers only the electrode portion 2 of the electro-acoustic component 1, a reduction in material and a reduction in manufacturing cost can be greatly expected. .

Next, FIG. 11 shows a second embodiment of the present invention. In this case, the conductive connector 20 is fitted into the pocket hole 11 of the holder 10 so as to be detachable. An insulating elastic resin body 21 having an oval shape, and arranged in a line at a predetermined pitch on a curved surface of the elastic resin body 21 so as to be pressed against the electroacoustic component 1 and the electrode of the circuit board 30. It is composed of a plurality of thin metal wires 22 having a substantially U-shape, and a separate rubber layer (not shown) is selectively adhered to the linear elevation of the elastic resin body 21.

The holder 10 and the conductive connector 20 are not separately formed, but may be integrally formed. The material of the elastic resin body 21 is the same as that of the elastic resin body 21 and the support layer 23. The other parts are the same as those in the above-described embodiment, and a description thereof will be omitted.

In this embodiment, the same operation and effect as those of the above embodiment can be expected, and it is extremely effective when the thin metal wires 22 cannot be buried linearly in the height direction of the flexible resin body 21. .

Next, FIG. 12 shows a third embodiment of the present invention. In this case, a block type in which the conductive connector 20 is detachably fitted into the pocket hole 11 of the holder 10 is shown. The elastic resin body 21 is made of a thin plate-shaped elastic insulating elastomer 25 and a conductive elastomer 26 alternately so that their joint surfaces are parallel to each other. In addition, a plurality of conductive elastomers 26 of the conductive resin body 21 are pressed against the electroacoustic component 1 and the electrodes of the circuit board 30 by multiplexing and arranging them in a horizontal row. .

The elastic resin body 21 has a hardness of 50 to 80 °, preferably 60 to 80 ° (JIS-

K 6 25 3 (measured by the test method of IS 0 7 6 1 9)). This hardness setting Therefore, even when the compression ratio is as small as 2 to 10% during conduction, uniform connection is possible, and buckling due to compression can be almost eliminated. In addition, a reliable and stable connection state can be obtained, and the load applied to the device is reduced, which can be expected to reduce the size and weight.

The elastic resin body 21 is manufactured by a method such as a printing method or a calendar method, but is preferably manufactured by a calendar method capable of stably producing. For example, an insulating elastomer 125 is formed into a thin film on a polyethylene terephthalate film by a calendar, and the film is heated and cured, and a conductive elastomer 126 is formed on the insulating elastomer 125 into a thin film by a calendar. The obtained laminated thin film is peeled off from the polyethylene terephthalate film, and a large number of the laminated thin films are laminated in the same order to form a block body, which is then sliced and cut to produce an elastic resin body 21. can do.

The insulating elastomer 25 and the conductive elastomer 26 differ only in whether or not a conductive material is added. The materials of the insulating elastomer 25 and the conductive elastomer 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, preferably 100 to 600 parts by weight, of a conductive material. This is because if the amount is less than 50 parts by weight, a sufficient resistance cannot be obtained, and the function as a connector cannot be expected. Conversely, if it is more than 800 parts by weight, the function as an elastic body is lacking.

The conductive materials of conductive elastomer 26 include carbon, graphite, gold, silver, gold alloy, copper, aluminum, aluminum-gay alloy, brass, phosphor bronze, beryllium copper, nickel, nickel-titanium alloy , Molybdenum, tungsten, stainless steel, iron, iron-carbon alloy, and other materials are used. The conductive material may have various particle shapes such as a spherical shape, an elliptical shape, and a flake shape. As the particles, metal particles, thermoplastic resin particles, thermosetting resin particles, silica particles, or the like may be subjected to a metal plating treatment as necessary. They are, A single type or a mixture of two or more types may be used, but silver-based or gold-based plating is preferred from the viewpoint of stability of the resistance value.

Note that the holder 10 and the conductive resin body 21, that is, the holder 10 and the conductive connector 20 can be integrally formed instead of separately. The other parts are the same as in the above embodiment, and the description is omitted.

In this embodiment, the same operation and effect as those in the above embodiment can be expected, and since it is not necessary to arrange a plurality of thin metal wires 22 in parallel, a reduction in the number of parts and an improvement in workability can be greatly expected. It is clear.

Next, FIGS. 13 to 16 (a) and (b) show a fourth embodiment of the present invention. In this case, the holder 10 is attached to the back electrode 2 of the electroacoustic component 1. It is bent and formed into an approximately L-shaped cross section to be overlaid and adhered or adhered. The conductive connector 20 is provided with a plurality of conductive wire members 27 interposed between the electrodes of the electroacoustic component 1 and the circuit board 30 and arranged obliquely with respect to the vertical approach direction. The first elastic insulative elastomer 28 that is partially adhered to the back surface of the conductive wire material 27 and contacts the electrode 3 of the electroacoustic component 1 and the front surface of the plurality of conductive wire materials 27 And an elastic second elastomer 28 A which is partially adhered to the electrodes of the circuit board 30 and is in contact with the electrodes of the circuit board 30. The first and second insulating elastomers 28 and 28 A are displaced substantially point-symmetrically and arranged in a substantially X-shaped cross-section with respect to the reference, and the exposed surface of the conductive wire material 27 and the first and second insulating elastomers The two insulating elastomers 28 and 28 A each define a contact area decreasing space 29 having a triangular cross section, and the holder 10 has a first insulating property. It is to be connected by bonding the ends of Rasutoma one 2 8. As shown in FIGS. 13 and 15 (a) and (b), the plurality of conductive wires 27 are arranged in a row at a predetermined pitch of, for example, 0.02 mm or more. I have. The plurality of conductive wires 27 extend linearly at a predetermined inclination angle, and the inclination angle is 30. ~ 60 °, preferably 45. Good range. 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 wire material 27. is there. Conversely, if the angle exceeds 60 °, the height of the connector for the electro-acoustic component is reduced, and the displacement caused by the compression of the connector for the electro-acoustic component cannot be absorbed.

Each conductive wire material 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 It is formed into an elongated plate, strip, or filament using a material such as a carbon alloy, and the surface is coated with gold or a gold alloy as needed. The surface of the conductive wire material 27 is degreased with a solvent as necessary in order to improve the adhesion with the first and second insulating elastomers 28-28A. Also, when the first and second insulating elastomers 28 and 28A are made of silicone rubber, an auxiliary agent for bonding with silicone rubber (for example, a silane coupling agent) is required to enhance the adhesiveness. It is applied according to.

The thickness of each conductive wire 27 is in the range of 0.01 to 0.5 mm, preferably in the range of 0.02 to 0.5 mm. This is because if the thickness is less than 0.01 mm, the strength of the material itself is lacking, there is no durability when used as a product, and the handling properties during molding deteriorate. On the other hand, if it exceeds 0.5 mm, the rigidity of the material is so high that it is difficult to suppress the connection load, and it becomes difficult to perform processing such as etching, laser, and stamping press.

In addition, the substantially central portion P in the length direction of the conductive wire material 27 refers to a point 12 near the length of the conductive wire material 27 or its vicinity.

The first and second insulating elastomers 28 and 28 A are made of elastic silicone rubber, polybutadiene rubber, natural rubber, polyisoprene rubber, urethane rubber, black rubber, polyester rubber, and styrene-butadiene. Non-foaming materials such as polymer rubber, epichlorohydrin rubber, etc., and using these foaming materials, bend into a roughly L-shaped, approximately V-shaped, approximately rectangular shape, etc. with a thick section extending in the depth direction in Fig. 12. At the time of manufacture, parts overlap with the conductor strip 27 in between. The first and second insulating layers having the same shape As the material for the last 28-28 A, among the above-mentioned materials, it is most preferable to use silicone rubber which is excellent in electric insulation, heat resistance, chemical resistance, heat resistance and compression set.

The hardness of the first and second insulating elastomers 28 and 28 A is preferably in the range of rubber hardness 10 ° to 70 ° H, and more preferably in the range of rubber hardness 30 ° to 60 ° H. This is because, if it is out of the range, the rubber hardness increases and the contact pressure increases. Also, if the rubber hardness is less than 30 ° H, stickiness peculiar to silicone rubber is generated on the surface after molding, and handling becomes difficult. Conversely, if the rubber hardness exceeds 60 ° H, the contact pressure will be higher than necessary.

Note that the holder 10 and the conductive connector 20 can be integrally formed, not separately. The other parts are the same as in the above-described embodiment, and a description thereof will be omitted.

In the above configuration, the holder 10 is attached or fixed to the electrode portion 2 of the electroacoustic component 1 with an adhesive or the like, and the conductive connector 20 is positioned and sandwiched between the electroacoustic component 1 and the circuit board 30. When the circuit board 30 is pressed down toward the electroacoustic component 1, the first and second insulating elastomers 28 and 28A functioning as elastic supports are compressed, and the electrodes of the electroacoustic component 1 are compressed. The electrodes of the circuit board 30 and the plurality of conductive wires 27 are reliably brought into contact with each other to conduct electricity.

In this embodiment, the same operation and effect as those of the above embodiment can be expected. In addition, the contact between the upper part and the lower part of the first and second insulating elastomers 28 and 28 A is a concave portion. Since each of the area reduction spaces 29 is formed, the contact area of the connection surface can be reduced. Further, since the connection pressure escapes in the direction of inclination of the plurality of conductive wires 27, the connection pressure is reduced, and as a result, the connection load can be greatly reduced with a simple configuration.

In addition, since a plurality of conductive wires 27 are inclined, the conductive wires 2

The buckling of No. 7 is suppressed and prevented, and the repetitive compressibility can be significantly improved. Specifically, it was confirmed that a stable conduction resistance could be obtained even after the compression was repeated 100 times. Furthermore, by changing the shape and hardness of the first and second insulating elastomers 28 and 28 A, the connection load can be controlled, so that the width and height dimensions of the product do not need to be significantly changed. However, the load can be set to any value. In the above embodiment, a plurality of fine metal wires 22 are arranged and embedded in two rows in the elastic resin body 21.However, the fine metal wires 22 are arranged and embedded in the elastic resin body 21 as an example. Or three or more rows. Further, in the fourth embodiment, the holder 10 is formed to bend into a substantially L-shaped cross section, but the present invention is not limited to this. For example, the holder 10 can be formed in a substantially plate-shaped cross section, a substantially C-shaped cross section, or a substantially J-shaped cross section. Further, the end of the second insulating elastomer 28 A may be bonded and connected to the holder 10.

Next, FIG. 17 shows a fifth embodiment of the present invention. In this case, a pair of conductive rubber pins which are arranged so that the conductive connectors 20 are arranged in the holder 10 at predetermined intervals and are supported through them are shown. Each conductive rubber pin 40 is formed using an elastic conductive elastomer 126, and the exposed upper and lower ends of the pair of conductive rubber pins 40 are connected to the electrodes of the electroacoustic component 1 and the circuit board 30. They are pressed against each other.

Each conductive rubber pin 40 may have a cylindrical shape as shown in the figure, but is not limited thereto, and may have an elliptical column shape, a prism shape, a triangular shape, a polygonal shape, or the like. In addition, the number can be increased to three, four, five, six, eight, etc., instead of two as shown. The other parts are the same as in the above embodiment, and the description is omitted.

It is apparent that the present embodiment can expect the same operation and effect as the above embodiment. Further, since the elastic resin body 21 and the insulating elastomer 25 can be omitted, the number of parts can be reduced and the configuration can be greatly simplified. Industrial applicability As described above, according to the present invention, even if repair is required, the electroacoustic component can be used again, and moreover, it is possible to effectively cope with a reduction in size and weight of a mobile phone or the like. effective. In addition, unstable connection resistance due to vibration of the electroacoustic component, fatigue of the connector, or unstable connection can be eliminated.
