Description

The present invention relates to an apparatus for attaching an electronic component having lead wires, such as a speaker, to an electronic device such as a wireless device and electrically connecting the electronic component to an internal circuit board.

FIG. 8 is an exploded perspective view illustrating the assembly structure of radio 9 using a typical prior art connection device. This wireless device 9 generally includes a lower housing 92 with an opening at the top, an upper housing (not shown) that is put thereon, an operation panel 94 provided on the front, and a terminal 95 such as an antenna provided on the back. It is composed of heat radiation fins 96 , an internal circuit board 97 , and a speaker 982 which is an electronic component having lead wires 981 .

In this specification, for the sake of simplification of explanation, the electronic component is used as described above, but it may be an electrical component as long as it has a lead wire 981 . Examples of the electric parts include electro-mechanical conversion parts such as the speaker 982 and mechanical-electrical conversion parts such as a microphone. As the lead wiring 981, not only a single core wire like the speaker 982 but also a flexible substrate or the like can be used in the case of a piezoelectric element.

The speaker 982 is a cone-shaped or dome-shaped general-purpose product (hereinafter, described as a cone-shaped speaker). A shaped frame 9824 extends, and the outer peripheral portion of the cone 9821 is fixed with a paper (gasket) 9825 at the outer peripheral portion of the frame 9824 . Both ends of the coil 9822 are soldered to a terminal block 9826 attached to the frame 9824, from which two lead wires 981 are led out. The speaker 982 is formed into a speaker unit (module) 98 by previously processing the ends of two lead wires 981 into a connector 983, which is a typical connecting device, by a speaker manufacturer.

The radio equipment 9 is generally assembled by assembling a terminal 95 such as the antenna, an internal circuit board 97 on which various parts are mounted, and a heat radiation fin 96 to the lower housing 92, and then an operation panel 94. However, the flexible cable is connected to the substrate 97, assembled to the lower housing 92, and completed by mounting the speaker 982 and assembling the upper housing. To assemble the speaker 982 , a hat-shaped rubber damper 99 is fitted in advance to the portion of the columnar magnet 9823 of the speaker 982 , the rubber damper 99 is formed to protrude from the lower housing 92 , and the substrate 97 is mounted. It is mounted on bosses 921 that are exposed through openings 971 formed in the . Before or after assembly of the speaker 982, the connector 983 is inserted and electrically connected to a connector 972 provided on the board 97 of the internal circuit. Thus, the temporarily fixed speaker 982 is permanently fixed by pressing the speaker 982 from the paper (gasket) 9825 portion of the speaker 982 by covering the upper housing.

In the conventional technology described above, connection of the connector 983 is a manual operation. Here, in the radio device 9, in the case of a large stationary radio device with high power such as an amateur radio or a business radio, the number of production units is not so large, and some products are made to order. It is assembled while the worker makes appropriate adjustments. On the other hand, in the case of relatively small hand-held and in-vehicle type radios, although the number of production units is larger than that of the above-mentioned stationary large radios, even at the level of, for example, mobile phone terminal equipment, which is very large. do not have. Therefore, it is not assembled on a long line, but is compactly assembled using multiple assembling machines and mounting machines. takes a lot of time to put together.

Therefore, if the connecting work of the connector 983 is performed manually, the actual working time of the worker is extremely short during the long assembly time, which is very inefficient. Especially for automatic production at night, a worker must be present. Also, the operator may forget to connect the connector 983 .

Therefore, Patent Document 1 discloses a speaker terminal structure suitable for robot production. According to this, a spring contact formed by bending a plate spring is used on the speaker side, and by assembling the housing, the spring contact is brought into contact with a contact formed on a substrate of an internal circuit. Therefore, the effect of eliminating the work of connector connection and shifting to assembly only by robots is very large. Two positive and negative terminals are provided, and the two terminals are arranged at an angle (intersecting each other) to prevent poor connection and instantaneous disconnection.

Japanese Patent Application Laid-Open No. 2020-65170

The above-described prior art is a speaker connection structure that can not only be adapted to robot production, but also can prevent the connection failure and instantaneous interruption. However, the wireless device is divided into front and rear housings, the speaker is previously screwed and fixed to the front housing, and a microphone, touch keys, display unit, etc. are also assembled to the front housing. Therefore, if this prior art is applied to the wireless device 9 of FIG. 8, the speaker 982, which is simply placed on the boss 921 from the substrate 97, is tilted and displaced due to the elastic force of the spring contact when the upper housing is assembled. may cause a connection failure.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic component connection device that can achieve assembly by a robot with high connection reliability when assembling an electronic component such as a speaker having lead wiring to an electronic device, and an electronic device using the same. is to provide

A connection device for an electronic component according to the present invention is a connection device for connecting an electronic component having a lead wire to an internal circuit of the electronic device when the lead wire is assembled into the electronic device, wherein the rigid frame is attached to the electronic component. and a pattern whose one end is rigidly supported by the frame so as to be swingable, or which is flexible and is attached to the frame and connected to the lead wiring, and the other end. a substrate having contacts extending from the pattern; contacts formed on the substrate of the internal circuit; spring contacts provided on one of the contacts of the substrate; It is interposed between the housing of the electronic device and pressed against the other end side of the substrate while the housing is assembled, so that the contacts of the substrate of the internal circuit and the contacts of the substrate are connected to the other side of the substrate. and a pressing member that brings the spring contacts into close contact with each other.

According to the above configuration, in the connection device for connecting the lead wiring to the internal circuit of the electronic device when assembling the electronic component having the lead wiring to the electronic device, the present invention includes a frame, a printed wiring board, or the like. A substrate, a spring contact and a pressing member are used.

Specifically, the frame has rigidity, is attached to the electronic component by press-fitting or adhesion, and supports the substrate. If the substrate is rigid, one end is swingably supported by the frame, or if the substrate is flexible, one end is attached (fixed) to the frame. A pattern is formed on the substrate, the lead wiring is connected to the pattern, and a contact is provided on the other end side of the substrate. A spring contact is interposed between the contact and a contact formed on the substrate of the internal circuit, and before the electronic component is assembled, the spring contact connects the contact of the internal circuit and the contact of the substrate. It is fixed on one side by soldering or the like. Then, when the housing is assembled, the pressing member presses the other end side of the board to bring the spring contact into close contact with the other side of the contact of the board of the internal circuit and the contact of the board.

Therefore, when assembling an electronic component having lead wires into an electronic device, the electronic component is assembled in advance into a module having a frame, a printed wiring board, a pressing member, and, in some cases, a spring contact. After assembling the housing, the lead wiring is electrically connected to the internal circuit from the substrate through both contacts and the spring contact. will be connected.

In this way, when assembling electronic parts having lead wires in the final assembly of an electronic device, manual work such as connector connection can be eliminated, and assembling by a robot can be realized. Further, the spring contact does not exhibit elastic force until it is pressed by the pressing member, that is, until the housing is finally assembled. Therefore, in a temporarily fixed state where the electronic component is only placed, the electronic component does not tilt due to the pressing force of the spring contact, and it is possible to obtain connection reliability of the spring contact and good assemblability. Furthermore, conventional electronic parts having lead wires and housings can be used as they are.

Further, in the electronic component connection device of the present invention, the electronic component is a speaker, and the frame includes an annular portion into which a magnet portion of the speaker is press-fitted, and one end of the substrate at an outer circumference of the annular portion. a locking member to which one end of the substrate is attached so as to be swingably supported; and a guide member that guides the side so as to be displaceable by swinging or bending.

According to the above construction, in the case of many cone-shaped or dome-shaped loudspeakers, the coil is soldered at both ends to a terminal block provided on the frame, and a single-core lead is connected to the terminal block. It is a structure in which two lines are drawn out. Speakers are used in various electronic devices for electro-mechanical conversion, that is, as sound output means, and are produced in large quantities. Therefore, there is no need to change the structure of the speaker itself (using a general-purpose product), and it can be assembled by a robot simply by pre-assembling the module with the frame, the printed wiring board, and, in some cases, the spring contact. and is preferred without significantly increasing cost.

Furthermore, when the speaker is a cone-shaped or dome-shaped speaker, the coil at the center of the cone or dome is fitted in a cylindrical magnet, and a trapezoidal frame extends from the magnet when viewed from the side. The outer peripheral portion of the cone is fixed with a paper sheet (gasket). When an annular portion of a frame made of sheet metal or the like is press-fitted into the columnar magnet portion, the frame is integrated with the frame of the speaker. For example, a pair of locking members, such as brackets, are suspended from the outer periphery of the annular portion of the frame. One end of the substrate is attached (fixed) to the stop member. On the other hand, from the outer periphery of the annular portion of the frame, a guide member is formed that extends beyond the frame of the speaker together with the substrate (outward) in the direction opposite to the engaging portion. This guide member guides the other end side of the substrate so as to be displaceable by swinging or bending, that is, so as not to fall off.

Therefore, when the housing is assembled, outside the frame of the speaker, the pressing member is pressed by the housing and presses the other end side of the substrate, so that the spring contact can be brought into close contact. In this way, existing cone-type or dome-type speakers can be applied to robot assembly.

Further, in the electronic component connection device of the present invention, the frame is made of a sheet metal part, the board is made of a rigid printed wiring board, and the locking member extends from the outer periphery of the annular portion toward the internal circuit board. The guide member has a notch for swingably supporting one end of the board on the side of the guide member, and the guide member is bent and formed to hang down toward the internal circuit board. A guide piece is provided, and the substrate has a guide hole penetrating in the thickness direction thereof and into which the guide piece is loosely inserted.

According to the above construction, the annular portion, the locking member and the guide member can be formed by sheet metal working, and the mounting of the substrate can be done simply by fitting one end into the notch and passing the guide piece through the guide hole. Well, you can cut costs.

Further, in the electronic component connecting device of the present invention, a non-return pawl is formed on the distal end side of the guide piece so as to protrude toward the base end side and engage around the guide hole. Characterized by

According to the above configuration, by simply fitting one end of the swingable substrate into the notch as described above and passing the guide piece through the guide hole, the non-return claw of the guide piece passes through the guide groove, When it reaches the opposite side of the substrate, it engages around the guide hole to prevent it from coming off. Therefore, assembly can be simplified.

Further, according to the present invention, there is provided an electronic component connection device for connecting a lead wire to an internal circuit of an electronic device when a speaker as an electronic component having a lead wire is assembled into the electronic device. In the frame, a locking member formed in the vicinity of the magnet portion; is mounted on one of a substrate having a pattern to which the lead wiring is connected and a contact extending from the pattern on the other end side, a contact formed on the substrate of the internal circuit, and a contact of the substrate. The spring contact is interposed between the other end of the substrate and the housing of the electronic device in the assembled state, and presses the other end of the substrate in the assembled state of the housing. and a pressing member for bringing the spring contact into close contact with the other side of the contact of the board of the internal circuit and the contact of the board.

According to the above configuration, in the connection device for connecting the lead wiring to the internal circuit of the electronic device when the speaker as an electronic component having the lead wiring is assembled to the electronic device, the present invention relates to the frame of the speaker. While a stop member is provided, a substrate such as a printed wiring board, spring contacts, and a pressure member are also used.

Specifically, the locking member is formed in the frame of the speaker in the vicinity of the magnet portion by sheet metal processing of the frame, has a hook-like shape, and supports the substrate. If the board is rigid, one end side is swingably supported by the locking member, or if the board is flexible, one end is attached (fixed) to the locking member. A pattern is formed on the substrate, the lead wiring is connected to the pattern, and a contact is provided on the other end side of the substrate. A spring contact is interposed between the contact and a contact formed on the substrate of the internal circuit, and the spring contact is one of the contact of the internal circuit and the contact of the substrate before assembly of the speaker. is fixed by soldering, etc. Then, when the housing is assembled, the pressing member presses the other end side of the board to bring the spring contact into close contact with the other side of the contact of the board of the internal circuit and the contact of the board.

Therefore, when assembling a speaker, which is an electronic component having lead wires, to an electronic device, a locking member is formed in the speaker, and the speaker is mounted in advance on a printed wiring board, a pressing member, and, in some cases, a spring contact. By assembling the module into a single module, simply mounting the modularized speaker at a predetermined position near the board of the internal circuit of the electronic device, once the housing is assembled, the lead wiring is connected to both contacts and the spring contact from the board. It will be electrically connected to the internal circuit via.

In this way, when assembling the speaker having such lead wires in the final assembly of the electronic device, manual work such as connector connection can be eliminated, and assembly by a robot can be realized. Further, the spring contact does not exhibit elastic force until it is pressed by the pressing member, that is, until the housing is finally assembled. Therefore, when the speaker is temporarily fixed only by placing it thereon, the speaker does not tilt due to the pressing force of the spring contact, and the connection reliability of the spring contact and good assembling performance can be obtained.

Further, in the electronic component connection device of the present invention, the locking member is formed by bending the frame of the speaker, and has a notch on the side of the pressing member for supporting one end of the substrate in a swingable manner. The other end side of the substrate is formed to have a narrow width, and both sides of the narrow portion of the substrate are guided to the side opposite to the locking member with respect to the magnet in the frame of the speaker. A guide member is provided that prevents the board from rotating around the axis of the speaker, and prevents the board from shifting in the radial direction of the speaker by holding the narrow stepped portion. characterized by

According to the above configuration, one end of the board is fitted into the notch of the locking member and is supported so as to be swingable. It is unstable when pressed by the pressing member. Therefore, while the other end side of the substrate is formed narrow, a guide member is provided on the side of the speaker frame opposite to the locking member with respect to the magnet. The guide member guides both sides of the narrow portion of the substrate, thereby preventing rotation of the substrate about the axis of the speaker. Further, by holding the narrow step portion, the substrate is prevented from coming off from the notch, and the substrate can be prevented from being displaced in the radial direction of the speaker. In this way, it is possible to obtain the connection reliability of the spring contacts and good assembling performance during the final assembly of the housing from the unstable temporarily fixed state.

Furthermore, an electronic device of the present invention includes the electronic component described above.

According to the above configuration, it is possible to realize an electronic device that can be assembled by a robot when an electronic component such as a speaker having lead wires is assembled to the electronic device and that can obtain connection reliability.

Preferably, the electronic device is implemented by a wireless device, particularly a relatively small handheld or vehicle-mounted wireless device. In that case, although the production volume is larger than that of stationary large wireless devices, it is not at the level of, for example, a mobile phone terminal device. Therefore, it is not assembled on a long line, but is assembled using multiple assembling machines and mounting machines, and each assembling machine and mounting machine assembles a large number of parts. It takes a long time to raise. Therefore, it is very effective to eliminate manual work such as connector connection and shift to assembly only by robots.

As described above, the connection device for an electronic component and the electronic device using the same according to the present invention are a connection device for connecting the lead wiring to the internal circuit of the electronic device when assembling the electronic component having the lead wiring to the electronic device. a frame is attached to the electronic component, a board such as a printed wiring board is oscillatably supported by the frame, or the board is made flexible, and the lead wiring is connected to the pattern of the board. A spring contact interposed between the contact provided at the tip of the pattern and the contact formed on the board of the internal circuit is pressed by the pressing member when the housing is assembled, and is in close contact. , to be electrically connected.

Therefore, by assembling electronic parts in advance into a module equipped with a frame, a printed wiring board, a pressing member, and in some cases, spring contacts, the modularized electronic parts can be used as substrates for the internal circuits of electronic equipment. Once the housing is assembled, the lead wiring is electrically connected to the internal circuit from the board via both contacts and the spring contact by simply mounting it at a predetermined position nearby. As a result, manual work such as connector connection can be eliminated, and assembly by a robot can be realized with high connection reliability. In addition, conventional electronic parts having lead wires and housings can be used as they are.

As described above, the connection device for electronic components and the electronic equipment using the same according to the present invention are configured such that when a speaker, which is an electronic component having lead wires, is assembled into the electronic equipment, the lead wires are connected to the internal circuit of the electronic equipment. In a connection device for connecting to a speaker, a locking member is attached to a frame of a speaker, a board such as a printed wiring board is supported swingably on the locking member, or the board is flexible, and the board is made flexible. The lead wiring is connected to the pattern, and the spring contact interposed between the contact provided at the tip of the pattern and the contact formed on the board of the internal circuit is a pressing member when the housing is assembled. They are pressed so that they are brought into close contact and electrically connected.

Therefore, by providing the speaker with a locking member and assembling the speaker in advance into a module on which a printed circuit board, a pressing member and, in some cases, a spring contact are attached, the modularized speaker can be used as an electronic device. After assembling the housing, the lead wiring is electrically connected to the internal circuit from the board via both contacts and the spring contact. As a result, manual work such as connector connection can be eliminated, and assembly by a robot can be realized with high connection reliability.

The frame 51 supports the substrate 52. In this embodiment, the substrate 52 is rigid and its one end 522 side is supported by the frame 51 so as to be swingable, but the substrate 52 is formed flexible. In that case, one end 522 of the substrate 52 is fixed to the locking portion 512 of the frame 51 by adhesion or the like. In that case, the guide member 514 guides the other end 524 of the substrate 52 so as to be flexible and displaceable.

Contacts 5251 and 5252 to which the lead wires 491 and 492 are soldered are formed near the bottom of the Y-shape or U-shape on the substrate 52 .

The spring contacts 53 and 54 are previously fixed by soldering to the contacts 21 and 22 on the board 2 side of the internal circuit, but may be soldered to the contacts 5271 and 5272 on the board 52 . In this embodiment, the respective positive and negative contacts 5271, 5272; 21, 22 (polarity is arbitrary) are of a single pattern, but spring contacts 53 , 54 consist of two pairs of contacts. Further, the contacts 5271 and 5272 are sequentially formed in the longitudinal direction of the connection portion 523 of the substrate 2, that is, from the base end side to the tip end side of the Y-shaped leg or I-shaped portion. Alternatively, both sides of the I-shaped portion may have mutually different poles, and the spring contacts 53, 54 may also have the same poles in the longitudinal direction.

(Embodiment 2)
FIG. 6 is an exploded perspective view of a speaker unit 3a using a connection device 5a of another embodiment of the present invention, and FIG. 7 is a perspective view of FIG. 6 assembled. This speaker unit 3a is similar to the above-described speaker unit 3, and corresponding parts are denoted by the same reference numerals, and description thereof will be omitted. It should be noted that in the speaker unit 3a of the present embodiment, the portion corresponding to the frame 51 in the connection device 5a is integrally attached to the frame 44a of the speaker 4a as the locking member 58 and the guide member 59. That is.

Specifically, the locking member 58 has the same function as that of the locking member 512 of the frame 51 described above, and is bent from the frame 44a near the magnet 43 so as to hang down from the frame 44a toward the substrate 2 of the internal circuit. , the guide member 59 side is formed like a pair of brackets having a notch 581 for swingably supporting one end 522 of the substrate 52a.

On the other hand, the guide member 59 corresponds to the guide member 514, and includes a fixing portion 591 fixed to the magnet 43 on the side opposite to the locking member 58 in the frame 44a of the speaker 4a, and A hanging piece 592 which is bent and hangs down on the substrate 2 side, and a pair of guides which divide the free end side of the hanging piece 592 into two and guide both sides of the other end 524 side of the substrate 52a. It comprises a piece 593 , a locking portion 594 connected to the guide piece 593 , and an introduction portion 595 connected to the locking portion 594 . The fixing portion 591 is fixed to the frame 44 together with the terminal block 46 by spot welding or the like.

Correspondingly, the other end 524 side of the connection portion 523a of the substrate 52a is formed with a narrow width by the step portion 5231, and the pair of guide pieces 593 guide both sides of this narrow portion. , the substrate 2a is prevented from rotating around the axis of the speaker 4a, and by holding the narrowed stepped portion 5241, the substrate 52a is prevented from being displaced in the radial direction of the speaker 4a. When the base plate 2a is fitted into the guide member 59, the hanging piece 592, the guide piece 593, the engaging portion 594 and the introduction portion 595 are bent by their elastic force, and the introduction portion 595, which is an oblique side, The wide portion on the base end side is guided from the stepped portion 5231 of the connecting portion 523a. Then, when the wide portion passes through the oblique side, the respective portions return due to elastic force, and the locking portion 594 holds the wide portion of the stepped portion 5231 to prevent it from coming off. Thus, the speaker unit 3a is assembled in advance by the manufacturer (integrated into a module).

With this configuration, when the speaker 4a, which is an electronic component having the lead wires 491 and 492, is assembled to the wireless device 1, which is an electronic device, the locking member 58 and the guide member 59 are formed on the speaker 4a. By assembling the speaker 4a in advance to the speaker unit 3a on which the substrate 52a, the pressing member 55, and in some cases the spring contacts 53 and 54 are attached, the speaker unit 3a is mounted on the substrate 2 of the internal circuit of the wireless device 1. When the housings 12 and 13 are assembled, the lead wires 491 and 492 are connected from the substrate 52a to the internal circuit via both contacts 5271 and 5272; 21 and 22 and spring contacts 53 and 54. will be electrically connected to

In this way, when assembling the speaker 4a having such lead wires 491 and 492 in the final assembly of the wireless device 1, manual work such as connector connection can be eliminated, and assembly by a robot can be realized. Also, the spring contacts 53 and 54 do not exert elastic force until they are pressed by the pressing member 55, that is, until the housings 12 and 13 are finally assembled. Therefore, when the speaker 4a is temporarily fixed only by placing it thereon, the speaker 4a does not tilt due to the pressing force of the spring contacts 53 and 54, and the connection reliability of the spring contacts 53 and 54 and good assembling performance are ensured. can be obtained.

In addition, since the base plate 52a is pivotably supported with its one end 522 fitted into the notch 581 of the locking member 58, it is temporarily mounted on the locking member 58 and the spring contacts 53 and 54. It is unstable in the fixed state and when pressed by the pressing member 55 . Therefore, while the other end 524a side of the substrate 52a is formed narrow, a guide member 59 is provided on the opposite side of the magnet 43 to the locking member 58 in the frame 44a of the speaker 4a. When the housings 12 and 13 are finally assembled from the temporarily fixed state, the spring contacts 53 and 54 can be reliably connected and good assemblability can be obtained.
