Abstract

In order to enable the construction of an electrical connector to become extremely simple, by omitting a circuit board or an electrical connector to be the intermeshing target, a stand-alone plug connector (10) was configured to intermesh directly with a wall section of a product casing (MF) that comprises an electronic device having a prescribed circuit, and since a contact section of a contact (12) was made to come in contact with a contact section of a wiring pattern (CP) that is exposed at the surface of a coupling protrusion section (Mfa), in a state of having the stand-alone plug connector (10) intermeshed, electrical connection of a signal transmission medium is achieved with a simple construction, without the intervention of circuit boards, or electrical connectors to be mounted onto the circuit board, which will be the intermeshing target of the signal transmission medium.

　一般に、携帯電話等の種々の電子機器又は電気機器において、細線同軸ケーブルやフレキシブル配線基板、或いは印刷配線基板等からなる各種信号電送媒体の端末部分を、電気コネクタを用いて印刷配線基板側に接続することが広く行われている（例えば下記の特許文献１参照）。このときの電気コネクタは、信号伝送媒体の端末部分を所定の配線パターン（回路）に接続するものであるが、通常は、例えば図１１に示されているように、製品筐体１の内部に取り付けられた回路基板２上にリセプタクルコネクタ３を実装しておき、そのリセプタクルコネクタ３に対して、細線同軸ケーブル等からなる信号伝送媒体４の端末部分を連結したプラグコネクタ５を嵌合させる構成になされている。なお、このときに用いられている一対の電気コネクタ３，５は、信号線を通して必要な情報信号の伝送を行うとともに、シールド線を通して接地用のシールド信号をグランド回路に接続させる機能を有している。 In general, in various electronic devices or electric devices such as mobile phones, terminal portions of various signal transmission media composed of fine coaxial cables, flexible wiring boards, printed wiring boards, etc. are connected to the printed wiring board side using electrical connectors. (See, for example, Patent Document 1 below). The electrical connector at this time is for connecting the terminal portion of the signal transmission medium to a predetermined wiring pattern (circuit). Usually, for example, as shown in FIG. The receptacle connector 3 is mounted on the attached circuit board 2, and the plug connector 5 in which the terminal portion of the signal transmission medium 4 made of a thin coaxial cable or the like is connected is fitted to the receptacle connector 3. Has been made. The pair of electrical connectors 3 and 5 used at this time has a function of transmitting a necessary information signal through the signal line and connecting a grounding shield signal to the ground circuit through the shield line. Yes.
　一方、近年になって電子機器等の小型化・薄型化が急速に進められており、それにともなって電気コネクタの低背化及び低コスト化が図られている。そのため、上述した電気コネクタ３，５の構成を簡易化することが強く要請されている。リセプタクルコネクタ３を省略するために製品筐体１上の導電路にプラグコネクタ５の接続脚部を直接半田付けすることも考えられるが、製品筐体１は、樹脂成形材料で製作されているため、耐熱性が低く製品筐体１に直接半田付けや電子部品の実装が出来ない状況である。従って、通常に用いられているいずれの電気コネクタも、配線パターンを有する印刷配線基板２に一方の電気コネクタ（リセプタクルコネクタ）３を実装し、他方の電気コネクタ（プラグコネクタ）５を嵌合状態とするという基本的な構成を備えたものとなっており、そのような基本的な構成の制約から、大幅な低背化及び低コスト化を図ることは難しくなって来ている。 On the other hand, in recent years, electronic devices and the like have been rapidly reduced in size and thickness, and accordingly, the height and cost of electrical connectors have been reduced. Therefore, there is a strong demand for simplifying the configuration of the electrical connectors 3 and 5 described above. In order to omit the receptacle connector 3, it is conceivable to directly solder the connecting leg portion of the plug connector 5 to the conductive path on the product housing 1, but the product housing 1 is made of a resin molding material. In this situation, heat resistance is low and soldering or electronic component mounting cannot be performed directly on the product casing 1. Accordingly, in any of the commonly used electrical connectors, one electrical connector (receptacle connector) 3 is mounted on a printed wiring board 2 having a wiring pattern, and the other electrical connector (plug connector) 5 is in a fitted state. Therefore, it has become difficult to achieve a significant reduction in height and cost due to the limitations of the basic configuration.

　図１～図６に示されている本発明の一実施形態にかかるプラグコネクタ１０は、所定の電子回路を有する携帯電話等の電子機器を構成している製品筐体ＭＦの壁部に対して直接的に嵌合される構成になされたものであって、その電子機器の製品筐体ＭＦを構成している壁部の内表面又は外表面には、アンテナや種々の回路の一部を構成する配線パターンＣＰが印刷等により形成されている。そして、この本発明の一実施形態にかかるプラグコネクタ１０を介して、製品筐体ＭＦの表面上に形成されている配線パターンＣＰに、信号伝送媒体としての細線同軸ケーブルＳＣの端末部分が電気的に接続されるようになっている。 A plug connector 10 according to an embodiment of the present invention shown in FIGS. 1 to 6 is connected to a wall portion of a product housing MF constituting an electronic device such as a mobile phone having a predetermined electronic circuit. It is configured to be directly fitted, and an antenna and a part of various circuits are formed on the inner surface or the outer surface of the wall portion constituting the product housing MF of the electronic device. A wiring pattern CP to be formed is formed by printing or the like. The terminal portion of the thin coaxial cable SC as the signal transmission medium is electrically connected to the wiring pattern CP formed on the surface of the product housing MF through the plug connector 10 according to the embodiment of the present invention. To be connected to.
　すなわち、上述した製品筐体ＭＦの壁部に設けられた一端縁部には、当該一端縁部から片持ち状に突出する連結突部ＭＦａが形成されており、その製品筐体ＭＦの壁部に設けられた連結突部ＭＦａにプラグコネクタ１０が嵌合されるようになっている。そのプラグコネクタ１０には、信号伝送媒体としての細線同軸ケーブルＳＣの端末部が後述するようにして連結されており、当該細線同軸ケーブルＳＣが連結された状態のプラグコネクタ１０が、まず図１及び図２に示されているように前記連結突部ＭＦａに対して略水平方向に対面するように配置される。その後、製品筐体ＭＦの壁部の表面と略平行な方向にプラグコネクタ１０が移動されていき、図５及び図６に示されているように前記連結突部ＭＦａの全体の外方をプラグコネクタ１０で覆うようにして嵌合が行われる。 That is, a connecting projection MFa projecting in a cantilevered manner from the one end edge is formed at one end edge provided on the wall of the product casing MF, and the wall of the product casing MF is formed. The plug connector 10 is adapted to be fitted to the connecting protrusion MFa provided on the connector. A terminal portion of a thin coaxial cable SC as a signal transmission medium is connected to the plug connector 10 as described later, and the plug connector 10 in a state where the fine coaxial cable SC is connected is first shown in FIG. As shown in FIG. 2, it is arranged so as to face the connection protrusion MFa in a substantially horizontal direction. Thereafter, the plug connector 10 is moved in a direction substantially parallel to the surface of the wall portion of the product housing MF, and as shown in FIGS. 5 and 6, the entire outside of the connecting projection MFa is plugged. The fitting is performed so as to cover the connector 10.
　このように、製品筐体ＭＦの連結突部ＭＦａにプラグコネクタ１０が嵌合された状態において、細線同軸ケーブルＳＣの端末部が配線パターンＣＰに接続されるようになっているが、以下、プラグコネクタ１０に関しては、当該プラグコネクタ１０を差し込む方向を前方向とし、それとは反対にプラグコネクタ１０を抜き出す抜去方向を後方向とする。また、連結突部ＭＦａに関しては、プラグコネクタ１０側に向かって突出する方向を前方向とし、それとは反対の方向を後方向とする。 As described above, the terminal portion of the thin coaxial cable SC is connected to the wiring pattern CP in a state where the plug connector 10 is fitted to the connection protrusion MFa of the product housing MF. Regarding the connector 10, the direction in which the plug connector 10 is inserted is defined as the forward direction, and the direction in which the plug connector 10 is removed is defined as the backward direction. Regarding the connecting protrusion MFa, the direction protruding toward the plug connector 10 is defined as the front direction, and the opposite direction is defined as the rear direction.
　このときの連結突部ＭＦａは、平面視において略矩形状をなす板状部材から形成されているが、当該連結突部ＭＦａの両側に相当する製品筐体ＭＦの壁部を溝状に切り込むようにして形成されている。この連結突部ＭＦａの外表面上には、上述した配線パターンＣＰの端末部分が、後方側から前方側、つまり当該連結突部ＭＦａの突出方向に向かって延在するように形成されており、連結突部ＭＦａの突出方向と直交する板幅方向の中央部分には信号導電路ＣＰａが配置されているとともに、その信号導電路ＣＰａに隣接する両側に、グランド導電路ＣＰｂが略平行に延出するように形成されている。これらの配線パターンＣＰを構成する信号導電路ＣＰａ、及びグランド導電路ＣＰｂは、前記連結突部ＭＦａの表面に露出するように形成されていて、それらの露出部分に接点部が設けられている。 The connection protrusion MFa at this time is formed from a plate-like member having a substantially rectangular shape in plan view, and the wall portions of the product housing MF corresponding to both sides of the connection protrusion MFa are cut into a groove shape. Is formed. On the outer surface of the connection protrusion MFa, the terminal portion of the wiring pattern CP described above is formed so as to extend from the rear side to the front side, that is, in the protruding direction of the connection protrusion MFa. A signal conductive path CPa is disposed in the central portion of the plate width direction perpendicular to the protruding direction of the connecting protrusion MFa, and the ground conductive path CPb extends substantially in parallel on both sides adjacent to the signal conductive path CPa. It is formed to do. The signal conductive path CPa and the ground conductive path CPb constituting these wiring patterns CP are formed so as to be exposed on the surface of the connection protrusion MFa, and a contact portion is provided in the exposed part.
　一方、プラグコネクタ１０は、前述したように連結突部ＭＦａに対して略水平に嵌合される水平嵌合型コネクタとして構成されたものであるが、そのプラグコネクタ１０の後方側の端縁部には、信号伝送媒体の一例としての細線同軸ケーブルＳＣの端末部分が連結されている。 On the other hand, the plug connector 10 is configured as a horizontal fitting type connector that is fitted substantially horizontally to the connecting protrusion MFa as described above. Are connected to a terminal portion of a thin coaxial cable SC as an example of a signal transmission medium.
　その信号伝送媒体としての細線同軸ケーブルＳＣの端末部分は、外周被覆材が皮剥きされることによってケーブル中心導体（信号線）ＳＣａ及びケーブル外部導体（シールド線）ＳＣｂが同軸状をなすように露出されており、当該細線同軸ケーブルＳＣの中心軸線に沿うようにして配置されたケーブル中心導体ＳＣａが、本体部としての絶縁ハウジング１１に取り付けられた信号用導電端子（シグナルコンタクト）１２に接続されることにより信号回路が構成される。また、上記ケーブル中心導体ＳＣａの外周側を取り囲むように配置されたケーブル外部導体ＳＣｂは、後述する導電性シェル１４に一体的に設けられたグランド用導電端子（グランドコンタクト）１３に接続され、それによってグランド回路が構成される。 The end portion of the thin coaxial cable SC as the signal transmission medium is exposed so that the cable center conductor (signal line) SCa and the cable outer conductor (shield line) SCb are coaxial when the outer peripheral covering material is peeled off. The cable center conductor SCa arranged along the center axis of the thin coaxial cable SC is connected to a signal conductive terminal (signal contact) 12 attached to the insulating housing 11 as the main body. Thus, a signal circuit is configured. The cable outer conductor SCb disposed so as to surround the outer peripheral side of the cable center conductor SCa is connected to a ground conductive terminal (ground contact) 13 provided integrally with a conductive shell 14 described later. Constitutes a ground circuit.
　このプラグコネクタ１０の本体部を構成する絶縁ハウジング１１は、上述したように細線同軸ケーブルＳＣ、信号用導電端子（シグナルコンタクト）１２及びグランド用導電端子（グランドコンタクト）１３を保持しており、製品筐体ＭＦ側の連結突部ＭＦａにプラグコネクタ１０が嵌合された際に、当該絶縁ハウジング１１が連結突部ＭＦａの上面側に配置されるようになっている。 The insulating housing 11 constituting the main body of the plug connector 10 holds the thin coaxial cable SC, the signal conductive terminal (signal contact) 12 and the ground conductive terminal (ground contact) 13 as described above. When the plug connector 10 is fitted to the connection protrusion MFa on the housing MF side, the insulating housing 11 is arranged on the upper surface side of the connection protrusion MFa.
　また、その絶縁ハウジング１１の外側表面は、薄板金属状部材からなる導電性シェル１４によって覆われている。この導電性シェル１４は、特に図７及び図８に示されているように、前記絶縁ハウジング１１の外周側面を環状に覆うシェル本体部１４ａと、絶縁ハウジング１１の上面部を覆うシェル蓋部１４ｂと、前記シェル本体部１４ａの下方側に配置されたシェル嵌合部１４ｃと、から構成されている。 The outer surface of the insulating housing 11 is covered with a conductive shell 14 made of a thin metal member. As shown in FIGS. 7 and 8, the conductive shell 14 includes a shell main body portion 14 a that covers the outer peripheral side surface of the insulating housing 11 in an annular shape and a shell lid portion 14 b that covers the upper surface portion of the insulating housing 11. And a shell fitting portion 14c disposed on the lower side of the shell main body portion 14a.
　このうちのシェル本体部１４ａは、平面視において略矩形状の環状体をなすように形成されており、上述したように絶縁ハウジング１１の側壁部を外周側から取り囲むように装着されている。また、このシェル本体部１４ａの両側壁部からは、横断面略「Ｕ」の字形状をなすシェル嵌合部１４ｃが下方に垂れ下がるように設けられている。このシェル嵌合部１４ｃは、上述した絶縁ハウジング１１と同様に本体部の一部を構成するものであって、内部が中空状をなすように形成されている。このシェル嵌合部１４ｃにおける略「Ｕ」の字形状の横断面形状は、前後方向において連続するように形成されており、それによって当該シェル嵌合部１４ｃの前端側の開口縁部に、上述した連結突部ＭＦａを受け入れる挿入嵌合口１４ｄが形成されている。 Among these, the shell main body portion 14a is formed so as to form a substantially rectangular annular body in plan view, and is mounted so as to surround the side wall portion of the insulating housing 11 from the outer peripheral side as described above. A shell fitting portion 14c having a substantially U-shaped cross section is provided so as to hang downward from both side wall portions of the shell main body portion 14a. The shell fitting portion 14c constitutes a part of the main body portion in the same manner as the insulating housing 11 described above, and is formed so that the inside is hollow. The substantially U-shaped cross-sectional shape of the shell fitting portion 14c is formed so as to be continuous in the front-rear direction, whereby the opening edge portion on the front end side of the shell fitting portion 14c has the above-described shape. An insertion fitting port 14d for receiving the connected projection MFa is formed.
　また、上述したシェル本体部１４ａの後端部分には、横断面略半円形状をなすケーブル支持部１４ｅが、後方側に向かって略水平に突出するように設けられており、そのケーブル支持部１４ｅの内壁面に対して、上述した細線同軸ケーブルＳＣの端末部分が載置されて受けられるようになっている。 Further, a cable support portion 14e having a substantially semicircular cross section is provided at the rear end portion of the shell body portion 14a described above so as to protrude substantially horizontally toward the rear side, and the cable support portion. The terminal portion of the thin coaxial cable SC described above is placed and received on the inner wall surface of 14e.
　さらに、前記導電性シェル１４のシェル蓋部１４ｂは、細線同軸ケーブルＳＣの端末部分を連結する前の初期状態においては、図７及び図８に示されているような開放状態になされている。すなわち、その初期状態におけるシェル蓋部１４ｂは、上述したケーブル支持部１４ｅの反対側、つまりシェル本体部１４ａの前端部分に、細幅状をなす連結板１４ｆを介して略鉛直上方に立ち上がるように形成されている。その連結板１４ｆの内表面側には、前記絶縁ハウジング１１から上方に立ち上がるように設けられた絶縁押圧板１１ａが沿うように配置されている。 Further, the shell cover portion 14b of the conductive shell 14 is in an open state as shown in FIGS. 7 and 8 in an initial state before connecting the terminal portion of the thin coaxial cable SC. That is, the shell lid portion 14b in the initial state stands up substantially vertically above the cable support portion 14e described above, that is, on the front end portion of the shell main body portion 14a via the connecting plate 14f having a narrow width. Is formed. On the inner surface side of the connecting plate 14f, an insulating pressing plate 11a provided so as to rise upward from the insulating housing 11 is arranged.
　そして、上述したような導電性シェル１４の開放状態において、細線同軸ケーブルＳＣの端末部分が、図９のようにケーブル支持部１４ｅに受けられるように載置されてセットされた後に、図１０に示されているようにして連結板１４ｆが、前記絶縁押圧板１１ｃとともに略直角に折り曲げられ、導電性シェル１４のシェル蓋部１４ｂが略水平状態まで回動するように押し倒される。これによって、絶縁ハウジング１１がシェル蓋部１４ｂにより上方側から覆われて導電性シェル１４が閉塞状態になされる。 Then, in the open state of the conductive shell 14 as described above, after the end portion of the thin coaxial cable SC is placed and set so as to be received by the cable support portion 14e as shown in FIG. As shown, the connecting plate 14f is bent at a substantially right angle together with the insulating pressing plate 11c, and the shell lid portion 14b of the conductive shell 14 is pushed down so as to rotate to a substantially horizontal state. As a result, the insulating housing 11 is covered from the upper side by the shell lid portion 14b, and the conductive shell 14 is closed.
　この閉塞された状態におけるシェル蓋部１４ｂは、シェル本体部１４ａの外周面を外側から覆うように被せられているとともに、上述したケーブル支持部１４ｅ及び細線同軸ケーブルＳＣを外側から覆うように構成になされている。すなわち、そのシェル蓋部１４ｂには、ケーブル支持部１４ｅ及び細線同軸ケーブルＳＣに相当する位置に、第１保持部１４ｇ及び第２保持部１４ｈが、横断面コの字形状をなすように設けられている。それらの第１保持部１４ｇ及び第２保持部１４ｈは、横断面コの字形状の開放側部分がケーブル支持部１４ｅ及び細線同軸ケーブルＳＣに対面するように形成されていて、前述したようにシェル蓋部１４ｂが略水平状態まで押し倒された際に、ケーブル支持部１４ｅ及び細線同軸ケーブルＳＣを縦断面コの字形状に覆うように構成されている。それらの第１保持部１４ｇ及び第２保持部１４ｈは、開放部分を構成している両側板状部材の先端部分が図１０の矢印Ａで示されているようにして内方側に折り曲げられ、カシメが行われることによって固定状態になされることにより、ケーブル外部導体ＳＣｂがケーブル支持部１４ｅと第１保持部１４ｇとに接触することで導電性シェル１４によるグランド回路が構成されることとなる。 The shell lid portion 14b in the closed state is configured to cover the outer peripheral surface of the shell main body portion 14a from the outside, and to cover the cable support portion 14e and the thin coaxial cable SC described above from the outside. Has been made. That is, in the shell lid portion 14b, the first holding portion 14g and the second holding portion 14h are provided at positions corresponding to the cable support portion 14e and the thin coaxial cable SC so as to form a U-shaped cross section. ing. The first holding portion 14g and the second holding portion 14h are formed so that the open side portion having a U-shaped cross section faces the cable support portion 14e and the thin coaxial cable SC, and as described above, When the cover part 14b is pushed down to a substantially horizontal state, the cable support part 14e and the thin coaxial cable SC are covered with a U-shaped longitudinal section. The first holding portion 14g and the second holding portion 14h are bent inward as shown by the arrow A in FIG. When the caulking is performed, the cable outer conductor SCb comes into contact with the cable support portion 14e and the first holding portion 14g, thereby forming a ground circuit by the conductive shell 14.
