Description

本発明は、プラグコネクタに関するものであり、特に、携帯電話、ＰＤＡ(携帯情報端末)、デジタルカメラ等の、携帯型電子機器に使用されるプラグコネクタに関するものである。   The present invention relates to a plug connector, and more particularly to a plug connector used in a portable electronic device such as a mobile phone, a PDA (personal digital assistant), and a digital camera.

近年、携帯電話、ＰＤＡ(携帯情報端末)、デジタルカメラ等の携帯型電子機器の市場が急速に広がっている。   In recent years, the market for portable electronic devices such as mobile phones, PDAs (personal digital assistants), and digital cameras has been rapidly expanding.

それらの携帯型電子機器を使用して、データ通信を行う場合や充電を行う際には、一般的に、プラグコネクタ付のケーブルが利用されている（例えば、特許文献１、特許文献２参照）。   When performing data communication or charging using such portable electronic devices, cables with plug connectors are generally used (see, for example, Patent Document 1 and Patent Document 2). .

これらのプラグコネクタは、相手方コネクタと電気的に接続されるプラグ部を有するハウジングと、プラグ部内のコンタクトピンに芯線をはんだ接続したケーブルとの接続部分の外側を、上記プラグ部の先端部分を露呈させ、かつ他の部分を、アッパーケースとロアケースの二つの部材に分割されている把持部材で覆い、コンタクトピンとケーブルとの接続部分に、ねじれ等が生じないように保護している。   These plug connectors expose the outside of the connection part between the housing having the plug part electrically connected to the mating connector and the cable in which the core wire is solder-connected to the contact pin in the plug part, and the tip part of the plug part. In addition, the other part is covered with a gripping member divided into two members, an upper case and a lower case, to protect the connection part between the contact pin and the cable from being twisted.

そのアッパーケースとロアケースの取り付け方としては、例えば特許文献１，特許文献２で知られるように、アッパーケースとロアケースを互いにビス止めする方法等が知られている。   As a method of attaching the upper case and the lower case, as known in Patent Documents 1 and 2, for example, a method of screwing the upper case and the lower case together is known.

また、図３および図４に示すプラグコネクタ１０１のように、アッパーケース１０２ａにフック１０３を設けるとともに、ロアケース１０２ｂにフック１０３が圧入または係合されるボス孔１０４を設けてなり、アッパーケース１０２ａとロアケース１０２ｂとの間にハウジング１０５を挟み、かつフック１０３とボス孔１０４との係合により、アッパーケース１０２ａとロアケース１０２ｂとを互いに止着して成るプラグコネクタも知られている。
特開２００５−８５４６９号公報（図１０）。 特開２００１−１８５２８２号公報。 3 and FIG. 4, the upper case 102a is provided with a hook 103, and the lower case 102b is provided with a boss hole 104 into which the hook 103 is press-fitted or engaged. There is also known a plug connector in which the housing 105 is sandwiched between the lower case 102b and the upper case 102a and the lower case 102b are fixed to each other by engaging the hook 103 and the boss hole 104.
Japanese Patent Laying-Open No. 2005-85469 (FIG. 10). JP 2001-185282 A.

しかしながら、プラグ部基部には、コンタクトピンが密集して配設されているので、特許文献１、特許文献２に記載されているプラグコネクタのように、アッパーケースとロアケースをビス止めする構造では、プラグ基部近傍にはネジ止め機構を設けることができない。このため、プラグ基部とは離れた、プラグコネクタの後端部側に偏らせてネジ止め機構を設けることになるので、固定が不安定で、プラグ基部近傍の合わせ部分がこじられると、不用意に開くという問題点があった。   However, since the contact pins are densely arranged in the plug base, in the structure in which the upper case and the lower case are screwed like the plug connectors described in Patent Document 1 and Patent Document 2, A screwing mechanism cannot be provided in the vicinity of the plug base. For this reason, since a screw fixing mechanism is provided by being biased toward the rear end side of the plug connector apart from the plug base, if the fixing is unstable and the mating part near the plug base is twisted, it is inadvertent There was a problem of opening.

一方、図４および図５に示すように、互いに圧入または係合されるフック１０３とボス孔１０４とで、アッパーケース１０２ａとロアケース１０２ｂを止着する構成では、ハウジング１０５を、アッパーケース１０２ａとロアケース１０２ｂとで挟み込む手段をとっているので、ケース１０２ａ，１０２ｂとハウジング１０５との間に隙間ができ、ガタツキが発生し易いという問題があった。また、フック１０３とボス孔１０４との止着部は、プラグ部近傍の左右二カ所だけで行っているので、開きやこじり力等に対しての強度が不
足するという難点もあった。 On the other hand, as shown in FIGS. 4 and 5, in the configuration in which the upper case 102a and the lower case 102b are fastened by the hook 103 and the boss hole 104 that are press-fitted or engaged with each other, the housing 105 is connected to the upper case 102a and the lower case. Since a means for sandwiching between the housings 102b is used, there is a problem that gaps are formed between the cases 102a and 102b and the housing 105, and rattling is likely to occur. In addition, since the fastening portion between the hook 103 and the boss hole 104 is provided at only two places on the left and right sides in the vicinity of the plug portion, there is a problem that the strength against the opening and twisting force is insufficient.

そこで、開きやこじりに対する強度が大きく、かつ、組立作業が容易な構造とするために解決すべき技術的課題が生じてくるのであり、本発明はこの課題を解決することを目的とする。   Therefore, a technical problem to be solved arises in order to obtain a structure that has a high strength against opening and twisting and that can be easily assembled, and the present invention aims to solve this problem.

本発明は上記目的を達成するために提案されたものであり、請求項１記載の発明は、相手方コネクタと電気的に接続されるプラグ部を有するハウジングと、該ハウジングの少なくとも外周の一部を囲って配設された把持部材とを備え、前記把持部材がアッパーケースとロアケースの二つのケースに分割されているプラグコネクタにおいて、前記ハウジングの前記プラグ部基部近傍における左右側面の上下２カ所に、それぞれ左右1対の上側フック部と左右１対の下側フック部とを設け、かつ前記アッパーケースの左右内側面に、前記左右1対の上側フック部と対応して、該上側フック部と嵌合可能なアッパーケース側フック部を各々設けるとともに、前記ロアケースの左右内側面に、前記左右１対の下側フック部と対応して、該左右１対の下側フック部と嵌合可能なロアケース側フック部を各々設けてなり、前記対応し合う各フック部を互いに嵌合させて、前記アッパーケースおよび前記ロアケースを前記ハウジングに取り付けたプラグコネクタを提供する。   The present invention has been proposed in order to achieve the above object, and the invention according to claim 1 includes a housing having a plug portion electrically connected to a mating connector, and at least a part of the outer periphery of the housing.

By the contact of the inclined surfaces 11, 18, and 13, 21, the hook portions 9B, 9B, 10B, 10B of the upper case 5A and the lower case 5B are released by elastic deformation toward the outer side, respectively, and the upper case 5A and The lower case 5B is allowed to be pushed in. Further, by pushing the upper case 5A and the lower case 5B, the pressure contact between the corresponding inclined surfaces 11, 18 and 13, 21 is released, and the abutting surface of the upper hook portion 9A. (The lower surface 12), the abutting surface (upper surface 19) of the upper case side hook portion 9B, and the abutting surface (upper surface 14) of the lower hook portion 10A and the abutting surface (lower surface 22) of the lower case side hook portion 10B. Will face each other, here with the elastic restoring force of the upper case 5A and the lower case 5B, The side hook portion 9B and the lower hook portion 10B are restored to their original positions, the abutting surfaces (12 and 19, 14 and 22) are fitted to each other, and the overlapping walls 17 and 20 are inserted into each other. In this state, the upper case 5 </ b> A and the lower case 5 </ b> B are attached and held on the housing 4, thereby completing the assembly of the plug connector 1.

したがって、このように構成されたプラグコネクタ１は、上側フック部９Ａとケース側フック部１０Ａとでなる係止手段２５ａ、および下側フック部９Ｂとケース側フック部１０Ｂとでなる係止手段２５ｂを用いて、アッパーケース５Ａおよびロアケース５Ｂをハウジング４に直接固定するので、アッパーケース５Ａとハウジング４との間のガタツキ、およびロアケース５Ｂとハウジング４との間のガタツキを無くした状態で、各ケース５Ａ，５Ｂをハウジング４に容易かつ、安定的に止着することができる。   Therefore, the plug connector 1 configured as described above includes the locking means 25a including the upper hook portion 9A and the case side hook portion 10A, and the locking means 25b including the lower hook portion 9B and the case side hook portion 10B. Since the upper case 5A and the lower case 5B are directly fixed to the housing 4, the cases between the upper case 5A and the housing 4 and the looseness between the lower case 5B and the housing 4 are eliminated. 5A and 5B can be fixed to the housing 4 easily and stably.

なお、上記実施の形態では、ハウジング４側における上下のフック部９Ａ，１０Ａとケース５Ａ，５Ｂにおけるフック部９Ｂ，１０Ｂの両方に、傾斜面(１１，１５，１８，２１)を形成した構造を開示したが、この傾斜面はハウジング４側における上下のフック部９Ａ，１０Ａとケース５Ａ，５Ｂにおけるフック部９Ｂ，１０Ｂのいずれか一方に設けることもできる。   In the above embodiment, the inclined surfaces (11, 15, 18, 21) are formed on both the upper and lower hook portions 9A, 10A on the housing 4 side and the hook portions 9B, 10B on the cases 5A, 5B. Although disclosed, this inclined surface can also be provided on either one of the upper and lower hook portions 9A, 10A on the housing 4 side and the hook portions 9B, 10B on the cases 5A, 5B.

また、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。   The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
