Description

本発明は、スピーカ端子と回路基板とを接続する端子接続構造及びその接続構造を備えた携帯無線通信機器に関する。 The present invention relates to a terminal connection structure for connecting a speaker terminal and a circuit board, and a mobile wireless communication device having the connection structure.

従来、スピーカ端子と回路基板との接続は、リード線の半田付けによって行われていた。リード線の半田付けは、接触不良や断線に対しては有利ではあるが、ロボットによる生産には不適であって生産効率が良くない。そこで、半田付けを行わず、生産自動化への対応のために、回路基板のスピーカ接続用回路座とスピーカの裏面に設けた板バネ端子とを対向圧接させる接続構造が開示されている（例えば特許文献１参照）。 Conventionally, speaker terminals and circuit boards are connected by soldering lead wires. Soldering the lead wires is advantageous in preventing poor contact and disconnection, but it is not suitable for robot production and the production efficiency is poor. Therefore, in order to cope with production automation without soldering, there has been disclosed a connection structure in which the speaker connection circuit seat of the circuit board and the leaf spring terminal provided on the back surface of the speaker are pressed against each other (for example, patent Reference 1).

また、同じく自動実装対応を図った、板ばね端子を用いた接続構造において、スピーカの軸方向に可動可能な一対の板ばね状端子の接点が、スピーカから略同じ距離にある一対の音響機器の音声出力端子と接続される構成とし、振動による接点不良に起因した瞬断等の防止を図ったものがある（例えば特許文献２参照）。また、コイルスプリングでプランジャーを付勢して成るプランジャータイプの接続端子が知られている。 In addition, in the connection structure using leaf spring terminals, which is also intended for automatic mounting, the contact points of a pair of leaf spring-shaped terminals movable in the axial direction of the speaker are connected to a pair of audio equipment at approximately the same distance from the speaker. There is a device that is configured to be connected to an audio output terminal to prevent momentary disconnection due to contact failure due to vibration (see, for example, Patent Document 2). Also known is a plunger type connection terminal in which a plunger is biased by a coil spring.

しかしながら、特許文献１に示されるような接続構造では、振動による接触不良が発生し易く、音声出力の瞬断や音声が出力されない問題を招く虞がある。また、特許文献２に示されるような接続構造は、一対の可動接点を、スピーカのヨークの両外側のフレーム外周に配置しているため、接続構造が大型化し、ハンディトランシーバのような小型の携帯機器に適用することは困難である。 However, in the connection structure as disclosed in Patent Document 1, contact failure due to vibration is likely to occur, and there is a risk of causing problems such as momentary interruption of audio output or no audio output. Further, in the connection structure as disclosed in Patent Document 2, since a pair of movable contacts are arranged on the outer periphery of the frame on both sides of the yoke of the speaker, the connection structure becomes large, and a compact mobile phone such as a handy transceiver is required. It is difficult to apply to equipment.

また、特許文献２には、可動接点を２つ設けることで、接点故障率の低減を図ることも開示されているが、これら可動接点は互いに平行する板ばね状端子に設けられているため、同じ方向の振動には弱いため、２つの接点が同時に接触不良を起こす虞がある。また、プランジャータイプの接続端子を用いると高価となる。 Further, Patent Document 2 discloses that the contact failure rate is reduced by providing two movable contacts. Since it is vulnerable to vibrations in the same direction, there is a risk that two contacts will cause poor contact at the same time. Moreover, using a plunger type connection terminal is expensive.

本発明は、上記問題を解消するものであり、振動や衝撃による接続不良や瞬間的な接続断を防止することができる、スピーカ端子と回路基板との端子接続構造及びそれを備えた携帯無線通信機器を提供することを目的とする。 DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and is capable of preventing poor connection and momentary disconnection due to vibration and impact, and a terminal connection structure between a speaker terminal and a circuit board, and portable wireless communication including the same.

It is characterized by being arranged in relation to each other.

また、上記接続構造において、バネ材接続端子は、各々が独立した板バネ材から成ることが望ましい。また、スピーカ側接続端子及び回路基板側接続端子のいずれか一方がバネ材接続端子で成り、他方が接点端子であってもよい。 Moreover, in the connection structure described above, it is desirable that each of the spring material connection terminals is made of an independent plate spring material . Also, one of the speaker side connection terminal and the circuit board side connection terminal may be a spring material connection terminal , and the other may be a contact terminal.

また、上記接続構造において、バネ材接続端子の＋極端子及び－極端子の各々が、それらの間を挟んで線対称に配置されていることが望ましい。 Moreover, in the above connection structure, it is desirable that each of the + electrode terminal and the - electrode terminal of the spring material connection terminal is arranged line-symmetrically with the gap between them interposed therebetween.

本発明によれば、スピーカ側接続端子及び回路基板側接続端子のいずれか一方が、方向性を有するバネ材接続端子で成り、他方の接続端子の＋極端子及び－極端子の各々に対して少なくとも２つずつ設けられ、その２つは互いに６０度～１２０度の範囲で所定の角度回転した位置関係に配置されているので、接続工数を削減しつつ安価に、振動や衝撃に強いスピーカ端子接続構造を得ることができる。
 According to the present invention, either one of the speaker-side connection terminal and the circuit board-side connection terminal is made of a spring material connection terminal having directionality, and the positive electrode terminal and the negative electrode terminal of the other connection terminal are At least two speaker terminals are provided, and the two are arranged in a positional relationship rotated by a predetermined angle in the range of 60 degrees to 120 degrees, so that the number of connection man-hours can be reduced, and the speaker terminals are resistant to vibration and impact at low cost.

以下、本発明の一実施形態に係るスピーカ端子接続構造及びそれを備えた携帯無線通信機器について、図面を参照して説明する。図１は、本実施形態に係るスピーカ端子接続構造を備えた携帯無線通信機器１を示す。携帯無線通信機器１は、フロントパネル２及びリアパネル３により構成されるハウジングを備え、フロントパネル２とリアパネル３とは、互いの開口端縁同士を突き合わせて結合される。フロントパネル２には、内装されたスピーカの音声出力用孔４、表示用のＬＣＤ５、操作ボタン６等が設けられている。リアパネル３には、回路基板等が内装されている。携帯無線通信機器１は、前記両パネル２，３の開口端縁同士が突き合わせ結合されることにより、互いに接触、接続されるスピーカ側接続端子と回路基板側接続端子を内装している。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A speaker terminal connection structure and a portable wireless communication device including the same according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a portable wireless communication device 1 having a speaker terminal connection structure according to this embodiment. A portable wireless communication device 1 has a housing composed of a front panel 2 and a rear panel 3, and the front panel 2 and the rear panel 3 are joined together with their opening edges facing each other. The front panel 2 is provided with an audio output hole 4 for an internal speaker, an LCD 5 for display, an operation button 6, and the like. A circuit board and the like are mounted inside the rear panel 3 . The portable wireless communication device 1 incorporates a speaker-side connection terminal and a circuit board-side connection terminal that are contacted and connected to each other by abutting and joining the opening edges of the panels 2 and 3 .

図２は、携帯無線通信機器１のリアパネル３に収納された回路基板７側を示す。図３は、携帯無線通信機器１のフロントパネル２に収納されたスピーカ１０側を示す。図３では、スピーカ１０の背面側のフレームやヨーク、接続端子９等が見えている。これらの図において、スピーカ１０はフロントパネル２に対して、また、回路基板７はリアパネル３に対して、それぞれ所定位置及び所定高さ位置に固定される。回路基板７は、リアパネル３の内面にネジ等により固定され、回路基板側接続端子８を備える。回路基板側接続端子８は、スピーカ側接続端子９と接触されるものであり、導電性のバネ材を用いた接続端子８１，８２から成る。この回路基板側接続端子８は、リアパネル３とフロントパネル２とが分離された状態でのリアパネル３の開口に面する回路基板７上の所定位置に設けられる。 FIG. 2 shows the side of the circuit board 7 housed in the rear panel 3 of the portable wireless communication device 1. As shown in FIG. FIG. 3 shows the side of the speaker 10 housed in the front panel 2 of the portable wireless communication device 1. As shown in FIG. In FIG. 3, the frame and yoke on the rear side of the speaker 10, the connection terminals 9, and the like are visible. In these figures, the speaker 10 is fixed to the front panel 2, and the circuit board 7 is fixed to the rear panel 3 at a predetermined position and at a predetermined height. The circuit board 7 is fixed to the inner surface of the rear panel 3 with screws or the like, and has circuit board side connection terminals 8 . The circuit board side connection terminals 8 are to be brought into contact with the speaker side connection terminals 9, and are composed of connection terminals 81 and 82 using a conductive spring material. The circuit board side connection terminal 8 is provided at a predetermined position on the circuit board 7 facing the opening of the rear panel 3 when the rear panel 3 and the front panel 2 are separated.

スピーカ１０は、フロントパネル２の前面にある音声出力用孔４から音声出力できるようにフロントパネル２にネジ等により固定され、回路基板側接続端子８と接触されるスピーカ側接続端子９を備える。スピーカ側接続端子９は、スピーカ１０の背面に備えられた＋極端子及び－極端子である導電材で成る接続端子９１，９２から成る。前記回路基板側接続端子８の接続端子８１，８２は、リアパネル３とフロントパネル２とが結合されたとき、回路基板７上の、スピーカ側接続端子９の接続端子９１，９１の各々と対向する位置に配置されている。接続端子８１，８２は、接続の確実化を図るため、＋極端子及び－極端子である接続端子９１，９１の各々に対して少なくとも２つずつ設けられている（この詳細は後述）。 The speaker 10 is fixed to the front panel 2 with screws or the like so that sound can be output from the sound output hole 4 on the front surface of the front panel 2, and has a speaker side connection terminal 9 that contacts the circuit board side connection terminal 8. The speaker-side connection terminal 9 is composed of connection terminals 91 and 92 made of a conductive material, which are a positive electrode terminal and a negative electrode terminal provided on the rear surface of the speaker 10 . The connection terminals 81 and 82 of the circuit board side connection terminals 8 are opposed to the connection terminals 91 and 91 of the speaker side connection terminals 9 on the circuit board 7 when the rear panel 3 and the front panel 2 are coupled. placed in position. At least two connection terminals 81 and 82 are provided for each of the connection terminals 91 and 91, which are + and - pole terminals, in order to ensure reliable connection (details of which will be described later).

このように構成された、リアパネル３（図２）とフロントパネル２（図３）との開口端縁同士を突き合わせて固定することで、回路基板側接続端子８（８１，８２）とスピーカ側接続端子９（９１，９２）とが圧接接触し、電気的に接続される。 By abutting and fixing the opening edges of the rear panel 3 (FIG. 2) and the front panel 2 (FIG. 3) configured in this way, the connection terminals 8 (81, 82) on the circuit board side and the speaker side are connected. The terminals 9 (91, 92) are press-contacted and electrically connected.

上記実施形態では、一方の回路基板側接続端子８にバネ材端子を用いて、他方のスピーカ側接続端子９には通常の接点端子（電極）を用いたものを示したが、スピーカ側接続端子９及び回路基板側接続端子８の両者にバネ材を用いたものであってもよい。一方に通常の接点端子（電極）を用いた場合、安価で低コスト化が図れる。また、両者にバネ材を用いた端子の場合は、接触の追従性が向上するため、接続のより高度な確実性が図れる。 In the above embodiment, one circuit board side connection terminal 8 uses a spring material terminal, and the other speaker side connection terminal 9 uses a normal contact terminal (electrode). A spring material may be used for both the connection terminals 9 and the circuit board side connection terminals 8 . If a normal contact terminal (electrode) is used on one side, the cost can be reduced. In addition, in the case of terminals using spring material for both, since followability of contact is improved, higher reliability of connection can be achieved.

次に、図４乃至図６を参照して、回路基板側接続端子８及びスピーカ側接続端子９の配置の詳細を説明する。 Next, the details of the arrangement of the circuit board side connection terminals 8 and the speaker side connection terminals 9 will be described with reference to FIGS. 4 to 6. FIG.

図４及び図５は、回路基板７上に設けられた回路基板側接続端子８の接続端子８１，８２を示す。接続端子８１は、バネ材端子８１Ａ，８１Ｂから成り、接続端子８２は、バネ材端子８２Ａ，８２Ｂから成る。これらバネ材端子８１Ａ，８１Ｂ，８２Ａ，８２Ｂは、金属板を折り曲げることにより形成されたものを用いればよい。 4 and 5 show connection terminals 81 and 82 of the circuit board side connection terminals 8 provided on the circuit board 7. FIG. The connection terminal 81 is composed of spring material terminals 81A and 81B, and the connection terminal 82 is composed of spring material terminals 82A and 82B. These spring material terminals 81A, 81B, 82A and 82B may be formed by bending a metal plate.

バネ材端子８１Ａとバネ材端子８１Ｂは、互いに所定の角度、例えば略９０度回転した位置関係（Ｌ字状）に配置され、同様に、バネ材端子８２Ａとバネ材端子８２Ｂも、互いに所定の角度、例えば略９０度回転した位置関係（Ｌ字状）に配置されている。これら互いに所定の角度、例えば略９０度回転した位置関係のものが、１対の接続端子となる。ここに、略９０度回転した位置関係とは、バネ材端子は、通常、応力が加わると撓む板バネ材を用いた構造であるため、端子自身に方向性を有していることに因る。また、バネ材端子８１Ａ，８１Ｂとバネ材端子８２Ａ，８２Ｂとは、それらの間（図５の一点鎖線ＣＬ）を挟んで線対称に配置されている。 The spring material terminals 81A and 81B are arranged in a positional relationship (L-shape) rotated by a predetermined angle, for example, approximately 90 degrees. They are arranged in a positional relationship (L-shaped) rotated by an angle, for example, approximately 90 degrees. A pair of connection terminals are formed by rotating them by a predetermined angle, for example, approximately 90 degrees. Here, the positional relationship in which the terminals are rotated by approximately 90 degrees is due to the fact that the terminals themselves have directionality because the spring material terminals usually have a structure using a plate spring material that bends when stress is applied. be. Further, the spring material terminals 81A, 81B and the spring material terminals 82A, 82B are arranged line-symmetrically across the gap (chain line CL in FIG. 5).

図６は、フロントパネル２に固定されたスピーカ１０側に設けられた接続端子９１，９２を示す。同図では、回路基板側の接続端子８１，８２がスピーカ側の接続端子９１，９２（電極）に接続される状況を、回路基板７を透視して示している。一方の接続端子９１は、スピーカの＋極端子であり、他方の接続端子９２は、スピーカの－極端子である。接続端子９１と接続端子９２とは、両者間を挟んで線対称に配置されている。＋極端子と－極端子とは逆であってもよい。接続端子９１には、接続端子８１のバネ材端子８１Ａ，８１Ｂが接続され、接続端子９２には、接続端子８２のバネ材端子８２Ａ，８２Ｂが接続される。 FIG. 6 shows connection terminals 91 and 92 provided on the speaker 10 side fixed to the front panel 2 . In the same figure, the circuit board 7 is seen through and the connection terminals 81 and 82 on the circuit board side are connected to the connection terminals 91 and 92 (electrodes) on the speaker side. One connection terminal 91 is the + pole terminal of the speaker, and the other connection terminal 92 is the - pole terminal of the speaker. The connection terminal 91 and the connection terminal 92 are arranged line-symmetrically with both of them interposed therebetween. The positive terminal and the negative terminal may be reversed. Spring material terminals 81 A and 81 B of the connection terminal 81 are connected to the connection terminal 91 , and spring material terminals 82 A and 82 B of the connection terminal 82 are connected to the connection terminal 92 .

なお、本実施形態では、スピーカ１０側の接続端子９１，９２として接点端子（電極）を用いたものを示したが、これらの接続端子９１，９２にも、バネ材端子を用いてもよい。その場合、接続端子９１，９２の各々において、少なくとも２つのバネ材端子は、互いに所定の角度、例えば略９０度回転した位置関係に配置され、又は、Ｌ字状に繋げた形状とすればよい。また、スピーカ側の接続端子９１，９２の大きさを、回路基板側の接続端子８１，８２の大きさより大きくしておくことが望ましい。また、スピーカ側の接続端子の各々において、少なくとも２つのバネ材端子とした場合、これらと回路基板側の２つの接続端子８１，８２とを接続した状態において、スピーカ側の接続端子と回路基板側の接続端子が所定の角度（例えば両者が直交する角度）をなすように配置してもよい。この場合、スピーカ側の接続端子９１，９２の大きさを回路基板側の接続端子８１，８２の大きさより必ずしも大きくしておく必要はない。また、スピーカ側の接続端子９１，９２としては、回路基板側の２つの接続端子８１，８２が接続できる面積の天面を有した直方体や立方体等を用いることもできる。このように回路基板側とスピーカ側の両者の接続端子にバネ材端子を用いる形態は、回路基板７とスピーカ１０との距離が離れている場合に好適である。 In this embodiment, contact terminals (electrodes) are used as the connection terminals 91 and 92 on the speaker 10 side, but these connection terminals 91 and 92 may also be spring material terminals. In that case, in each of the connection terminals 91 and 92, at least two spring material terminals may be arranged in a positional relationship rotated by a predetermined angle, for example, approximately 90 degrees, or may be connected in an L shape. . Moreover, it is desirable that the size of the connection terminals 91 and 92 on the speaker side is larger than the size of the connection terminals 81 and 82 on the circuit board side. Further, when at least two spring material terminals are used in each of the connection terminals on the speaker side, when these terminals are connected to the two connection terminals 81 and 82 on the circuit board side, the connection terminals on the speaker side and the circuit board side are connected to each other. may be arranged so as to form a predetermined angle (for example, an angle at which the two are perpendicular to each other). In this case, the size of the connection terminals 91 and 92 on the speaker side need not necessarily be larger than the size of the connection terminals 81 and 82 on the circuit board side. Moreover, as the connection terminals 91 and 92 on the speaker side, a rectangular parallelepiped, a cube, or the like having a top surface large enough to connect the two connection terminals 81 and 82 on the circuit board can be used. Such a form in which spring material terminals are used for both connection terminals on the circuit board side and the speaker side is suitable when the circuit board 7 and the speaker 10 are separated from each other.

図７は、回路基板７側の接続端子８１の一つであるバネ材端子８１Ａと、スピーカ１０側の接続端子９の一つである接点端子９１との接続部を示し、接続前と接続後の状態を示している。接続後には、バネ材端子８１Ａが接点端子９１に押圧力をもって当接され、バネ材端子８１Ａが撓んだ状態となり、接触接続は確実なものとなる。他の接続部も同様である。このようにして、携帯無線通信機器１として、リアパネル３とフロントパネル２とが固定された状態では、回路基板７側のバネ材端子８１Ａ，８１Ｂは、スピーカ１０側の接点端子９１にそれぞれ接触接続され、また、回路基板７側のバネ材端子８２Ａ，８２Ｂは、スピーカ１０側の接点端子９２にそれぞれ接触接続される。 FIG. 7 shows a connection portion between a spring material terminal 81A, which is one of the connection terminals 81 on the circuit board 7 side, and a contact terminal 91, which is one of the connection terminals 9 on the speaker 10 side, before connection and after connection. state. After the connection, the spring material terminal 81A is brought into contact with the contact terminal 91 with a pressing force, and the spring material terminal 81A is in a flexed state, so that the contact connection is assured. The same applies to other connections. In this manner, when the rear panel 3 and the front panel 2 of the mobile radio communication device 1 are fixed, the spring material terminals 81A and 81B on the circuit board 7 side are contact-connected to the contact terminals 91 on the speaker 10 side. The spring material terminals 82A and 82B on the circuit board 7 side are connected to contact terminals 92 on the speaker 10 side, respectively.

上記のように構成された本実施形態の端子接続構造の作用効果を説明する。携帯無線通信機器１に振動が加わったとき、互いに接触している接続端子８１と接続端子９１、接続端子８２と接続端子９２の各々にズレが生じることがある。そのとき、各々所定の角度、例えば略９０度回転した位置関係にある１対の接続端子を用いているため、ズレの方向が１対の接続端子のそれぞれで異なる。このため、一対のうちの、一方の接続端子（バネ材端子、接点端子）が接触不良や断線を起こしたとしても、他方の接続端子（バネ材端子、接点端子）は接続を維持することができる。従って、振動や衝撃による接続不良を防止し、回避することができる。 The effects of the terminal connection structure of this embodiment configured as described above will be described. When vibration is applied to the portable wireless communication device 1, the connection terminals 81 and 91, and the connection terminals 82 and 92, which are in contact with each other, may be displaced. At this time, since a pair of connection terminals are used in a positional relationship rotated by a predetermined angle, for example, approximately 90 degrees, the directions of displacement are different for each of the pair of connection terminals. Therefore, even if one of the pair of connection terminals (spring material terminal, contact terminal) causes contact failure or disconnection, the other connection terminal (spring material terminal, contact terminal) can maintain connection. can. Therefore, it is possible to prevent and avoid poor connection due to vibration and impact.

上記のように、１対の接点端子が、互いに所定の角度、例えば略９０度回転した位置関係にあるのは、振動が加わったときに接触位置にズレが生じても接触不良が生じないようにするためであって、位置関係は、上記作用効果が得られる範囲内であれば、例えば６０度～１２０の範囲であっても構わない。本請求の範囲でいう「所定の角度回転」は、そのような場合をも含む。 As described above, the pair of contact terminals are rotated by a predetermined angle, for example, approximately 90 degrees, so that contact failure does not occur even if the contact positions are displaced when vibration is applied. The positional relationship may be in the range of 60 degrees to 120 degrees, for example, as long as the above effects are obtained. "Predetermined angle rotation" as used in the claims includes such a case.

また、バネ材端子８１Ａ、８１Ｂとバネ材端子８２Ａ，８２Ｂとが線対称に配置され、また、接点端子９１と接点端子９２とが線対称に配置されているので、対称軸の左右でバランスが取れ、接触圧を均等にすることが容易となる。 Further, since the spring material terminals 81A, 81B and the spring material terminals 82A, 82B are arranged line-symmetrically, and the contact terminals 91 and 92 are arranged line-symmetrically, the left and right balance of the axis of symmetry is balanced. This makes it easy to equalize the contact pressure.

また、上記構成により、半田付けを行わず、生産自動化への対応が可能で、生産工数が少なく、さらには、高価なプランジャータイプの接続端子を用いる必要がなくなり、安価な接続構造を提供することができる。 In addition, with the above configuration, soldering is not required, production automation is possible, production man-hours are small, and the need to use expensive plunger-type connection terminals is eliminated, thereby providing an inexpensive connection structure. be able to.

なお、本発明は、上記実施形態の構成に限られず、種々の変形が可能である。例えば、上記実施形態では、スピーカ１０側の接続端子９１，９２として接点端子（電極）を用い、回路基板７側の接続端子８１，８２として、バネ材端子８１Ａ，８１Ｂ，８２Ａ，８２Ｂを用いたものを示したが、これとは逆に、前者にバネ材端子、後者に接点端子（電極）を用いてもよい。また、バネ材端子８１Ａ、８１Ｂとバネ材端子８２Ａ，８２Ｂとが線対称に配置され、接点端子９１と接点端子９２とが線対称に配置されているものを示したが、必ずしも、線対称でなくてもよい。また、上記実施形態では、互いに所定の角度、例えば略９０度回転した位置関係の１対の接続端子や接点端子の配置が、Ｌ字状になっているが、これに限られるものではなく、例えば逆Ｌ字状、Ｔ字状等、２つの方向性を持つもの、さらには、スター状の３つの方向性を持つものあっても構わない。 The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, in the above embodiment, contact terminals (electrodes) are used as the connection terminals 91 and 92 on the speaker 10 side, and spring material terminals 81A, 81B, 82A and 82B are used as the connection terminals 81 and 82 on the circuit board 7 side. However, on the contrary, it is also possible to use a spring material terminal for the former and a contact terminal (electrode) for the latter. Further, although the spring material terminals 81A, 81B and the spring material terminals 82A, 82B are arranged line-symmetrically, and the contact terminals 91 and 92 are arranged line-symmetrically, they are not necessarily line-symmetrical. It doesn't have to be. In the above embodiment, a pair of connection terminals and contact terminals that are rotated by a predetermined angle, for example, approximately 90 degrees, are arranged in an L-shape, but the arrangement is not limited to this. For example, there may be an inverted L shape, a T shape, or the like having two orientations, or a star shape having three orientations.
