Description

本発明は、通信機能付コネクタ装置及びそれに関連する技術に関するものである。   The present invention relates to a connector device with a communication function and a technology related thereto.

近年、自動車の低燃費性向上、乗員の快適性向上といった機能を充実させる目的で、車両に搭載される負荷やセンサ等の電装機器数は増加する一途にある。   In recent years, the number of electrical devices such as loads and sensors mounted on vehicles has been increasing for the purpose of enhancing functions such as improving fuel efficiency of automobiles and improving passenger comfort.

これに伴い、ワイヤーハーネスの回路数も増加しているが、ワイヤーハーネスの配索スペースの制約から、回路数の削減が要求されている。   Along with this, the number of circuits in the wire harness is also increasing, but due to restrictions on the wiring space of the wire harness, a reduction in the number of circuits is required.

その方策のひとつとして、信号多重化による信号線の削減がある。これに対応するため、負荷制御等を行う制御回路及び通信制御回路を組み込んだ通信機能付コネクタ装置を、電子制御装置（ＥＣＵ）、モータ等の各種負荷、センサ等に接続した技術が考えられている。   One measure is to reduce signal lines by signal multiplexing. In order to cope with this, there is considered a technology in which a control circuit for performing load control and the like and a connector device with a communication function incorporating a communication control circuit are connected to various loads such as an electronic control unit (ECU), a motor, a sensor, etc. Yes.

この種の通信機能付コネクタ装置は、例えば、電子制御装置に接続されると共に、所定の通信ラインを介して他の電子制御装置に接続される。これにより、車内で、複数の電子制御装置による通信ネットワークを構成する。そして、各通信機能付コネクタ装置間で、所定のプロトコル（例えばＣＡＮ等）に従い、データ通信を行う。あるいは、各電装機器に接続されると共に、所定の通信ラインを介して電子制御装置に接続される。そして、電子制御装置と各通信機能付コネクタ装置との間で多重通信を行い、各通信機能付コネクタ装置が、電子制御装置からの制御指令に基づいて各負荷制御を行ったり、また、センサからの出力を受けてこれを電子制御装置に与える構成となっている。   This type of connector device with a communication function is connected to, for example, an electronic control device and connected to another electronic control device via a predetermined communication line. Thereby, the communication network by a some electronic control apparatus is comprised in a vehicle. Then, data communication is performed between the connector devices with communication functions according to a predetermined protocol (for example, CAN). Or it is connected to each electrical equipment, and is connected to an electronic control unit via a predetermined communication line. Then, multiplex communication is performed between the electronic control device and each communication function connector device, and each communication function connector device performs each load control based on a control command from the electronic control device. The output is given to the electronic control unit.

ところで、上記のような通信機能付コネクタ装置では、所定の通信制御機能を持たせるために、制御用ＩＣ等の電子部品を含む通信制御回路を組み込んだ上で、小型化を図る必要がある。   By the way, in the connector device with a communication function as described above, in order to have a predetermined communication control function, it is necessary to reduce the size after incorporating a communication control circuit including electronic components such as a control IC.

そのための構成としては、コネクタハウジングの内面側にメッキ等により所定の回路パターンを形成してこれに電子部品を実装して、所定の制御回路を形成する構成が想定される。   As a configuration for that purpose, a configuration in which a predetermined circuit pattern is formed on the inner surface side of the connector housing by plating or the like and an electronic component is mounted thereon to form a predetermined control circuit is assumed.

この場合に、生産性の観点からすると、コネクタハウジングを２分割構成にし、それぞれの分割ハウジング内面にメッキ等で所定の回路パターンを形成すると共に、電子部品を実装した後、両分割ハウジングを合体させることが好ましい。   In this case, from the viewpoint of productivity, the connector housing is divided into two parts, a predetermined circuit pattern is formed on the inner surface of each divided housing by plating or the like, and after mounting the electronic parts, the two divided housings are combined. It is preferable.

この場合、両分割ハウジングの回路を電気的に接続する構成としては、フレキシブルプリント回路基板（ＦＰＣ）やフレキシブルフラットケーブル（ＦＦＣ）等の柔軟性を持つ配線材を用いて接続する構成や、半田付により接続する構成等が考えられる。   In this case, as a configuration for electrically connecting the circuits of the two divided housings, a configuration in which a flexible wiring material such as a flexible printed circuit board (FPC) or a flexible flat cable (FFC) is used, or soldering is used. The structure etc. which connect by can be considered.

なお、金属メッキにより所定の回路パターンを形成した技術は、特許文献１に開示されている。   A technique for forming a predetermined circuit pattern by metal plating is disclosed in Patent Document 1.

特開平７−２９４７７７号公報JP 7-294777 A

しかしながら、ＦＰＣやＦＦＣ等の配線材を用いて接続する構成では、コネクタ装置の大型化を招くことになる。   However, in the configuration in which connection is made using a wiring material such as FPC or FFC, the size of the connector device is increased.

また、通信機能付コネクタ装置を自動車に搭載する場合、車体の内部に雨水等が入りこんでもいいように、通信機能付コネクタ装置自体に防水機能を持たせる必要がある。   When the connector device with a communication function is mounted on an automobile, the connector device with a communication function itself needs to have a waterproof function so that rainwater or the like may enter the vehicle body.

そこで、本発明の課題は、通信機能付コネクタ装置の小型化を図りつつ、内部に組み込まれた配線パターンや電子部品等について防水機能を確保できる技術を提供することにある。   Accordingly, an object of the present invention is to provide a technique capable of ensuring a waterproof function for a wiring pattern, an electronic component, or the like incorporated therein while reducing the size of a connector device with a communication function.

上記課題を解決すべく、請求項１に記載の発明は、外部配線と電子機器とに接続される通信機能付コネクタ装置であって、基部と当該基部の一面に突出形成されて所定の雌型コネクタの嵌合孔に嵌入される嵌合凸部とを備え且つ複数の分割ハウジングの合体により構成されるコネクタハウジングと、前記各分割ハウジングのそれぞれの内面側に形成された制御回路部とを備え、前記各分割ハウジング同士の接合部分が、前記嵌合凸部のみに限定されたものである。   In order to solve the above-mentioned problem, the invention according to claim 1 is a connector device with a communication function connected to an external wiring and an electronic device, and is formed so as to project from a base and one surface of the base to a predetermined female type. A connector housing having a fitting convex portion to be fitted into the fitting hole of the connector and configured by combining a plurality of divided housings, and a control circuit portion formed on the inner surface side of each of the divided housings. The joining portion between the divided housings is limited only to the fitting convex portion.

請求項２に記載の発明は、請求項１に記載の通信機能付コネクタ装置であって、前記コネクタハウジングの前記嵌合凸部の基端部において、前記雌型コネクタの先端部に当接して当該雌型コネクタの嵌合孔への浸水を防止する防水部材とを備えるものである。   The invention according to claim 2 is the connector device with communication function according to claim 1, wherein the proximal end portion of the fitting convex portion of the connector housing is in contact with the distal end portion of the female connector. And a waterproof member that prevents water from entering the fitting hole of the female connector.

請求項１に記載の発明の通信機能付コネクタ装置は、通信機能付コネクタ装置の小型化を図るために、複数の分割ハウジングを合体させることで制御回路部を形成する構造を採用する。この場合に、各分割ハウジング同士の接合部分が、嵌合凸部に限定されており、雌型コネクタの嵌合孔からはみ出したコネクタハウジングの基部においては、両分割ハウジング同士の接合部分が存在していない。即ち、両分割ハウジング同士の接合部分は、防水機能を付与しにくい基部の部分に位置することなく、雌型コネクタの嵌合孔の内部に嵌入される。したがって、雌型コネクタの嵌合孔内に位置するコネクタハウジングの嵌合凸部が浸水に晒されるのを防止でき、両分割ハウジング同士の接合部分の防水機能を確保できる。   In order to reduce the size of the connector device with a communication function, the connector device with a communication function according to claim 1 employs a structure in which a control circuit portion is formed by combining a plurality of divided housings. In this case, the joint portion between the divided housings is limited to the fitting convex portion, and the joint portion between the two divided housings exists at the base portion of the connector housing that protrudes from the fitting hole of the female connector. Not. That is, the joint portion between the two divided housings is fitted into the fitting hole of the female connector without being positioned at the base portion where it is difficult to provide a waterproof function. Therefore, the fitting convex part of the connector housing located in the fitting hole of the female connector can be prevented from being exposed to water, and the waterproof function of the joint part between the two divided housings can be secured.

請求項２に記載の発明の通信機能付コネクタ装置は、嵌合凸部が雌型コネクタの嵌合孔内に嵌入される際に、雌型コネクタの先端部が防水部材に当接し、この防水部材自身の弾性復元力により雌型コネクタとの間の間隙が埋められて、この間隙が水密状に保持される。したがって、両分割ハウジング同士の接合部分の防水機能を確実に確保できる。   In the connector device with a communication function according to the second aspect of the present invention, when the fitting convex portion is fitted into the fitting hole of the female connector, the distal end portion of the female connector comes into contact with the waterproof member. The gap between the female connector and the female connector is filled by the elastic restoring force of the member itself, and the gap is held in a watertight manner. Therefore, the waterproof function of the joint portion between the two divided housings can be reliably ensured.

以下、この発明の実施形態に係る通信機能付コネクタ装置について説明する。   Hereinafter, a connector device with a communication function according to an embodiment of the present invention will be described.

The connector device 10 with a communication function is interposed between the electrical equipment 3 and the connection cable 4, and is fitted and connected to a connector fitting portion (not shown) provided in the electrical equipment 3. Fixing is performed. And the communication address is set with respect to each connector apparatus 10 with a communication function, and each connector apparatus 10 with a communication function is electrical equipment based on the control signal multiplexed and given via the connection cable 4 from ECU2. 3 or various signals from the electrical equipment 3 side are given to the ECU 2 side.

図３は、通信機能付コネクタ装置を示す斜視図であり、図４は同じくその側面視説明図であり、図５及び図６はこの通信機能付コネクタ装置と雌型コネクタとの嵌合動作を示す図である。   FIG. 3 is a perspective view showing the connector device with a communication function, FIG. 4 is also a side view explanatory view thereof, and FIGS. 5 and 6 illustrate the fitting operation between the connector device with the communication function and the female connector. FIG.

この通信機能付コネクタ装置１０は、図５及び図６に示すような所定の雌型コネクタ４０の嵌合孔４３に嵌合するための嵌合凸部１１を有した雄型コネクタの構成とされており、具体的に、この通信機能付コネクタ装置１０は、嵌合凸部１１が形成されたコネクタハウジング１２と、このコネクタハウジング１２内に収納された制御回路部（図示省略）と、防水部材（ゴムシール）１４とを備えている。   This connector device 10 with a communication function is configured as a male connector having a fitting convex portion 11 for fitting into a fitting hole 43 of a predetermined female connector 40 as shown in FIGS. Specifically, the connector device 10 with a communication function includes a connector housing 12 in which a fitting convex portion 11 is formed, a control circuit portion (not shown) housed in the connector housing 12, and a waterproof member. (Rubber seal) 14.

コネクタハウジング１２は、内部に電子機器との接続用の端子部や、所定の制御回路を構成するための電子部品等の制御回路部が収容可能に形成されており、特に、その嵌合凸部１１が、その扁平方向に沿って第１及び第２の複数の分割ハウジング２０，３０に２分割され、これらの一対の分割ハウジング２０，３０の合体により構成されている。   The connector housing 12 is formed such that a terminal portion for connection to an electronic device and a control circuit portion such as an electronic component for constituting a predetermined control circuit can be accommodated therein. 11 is divided into a first and a second plurality of divided housings 20 and 30 along the flat direction, and is constituted by a combination of the pair of divided housings 20 and 30.

各分割ハウジング２０，３０は、絶縁性樹脂のモールド成型品等、絶縁性材料により形成されている。   Each of the divided housings 20 and 30 is formed of an insulating material such as a molded product of an insulating resin.

このうち、第１の分割ハウジング２０は、コネクタハウジング１２の嵌合凸部１１において、その扁平方向に沿って２分割されたうちの上側部分を構成している。   Among these, the 1st division | segmentation housing 20 comprises the upper part of the 2nd division | segmentation in the fitting convex part 11 of the connector housing 12 along the flat direction.

また、第２の分割ハウジング３０は、コネクタハウジング１２の基部１５と、コネクタハウジング１２の嵌合凸部１１においてその扁平方向に沿って２分割されたうちの下側部分１６とが一体的に連結された構造となっている。   The second divided housing 30 is integrally connected to the base portion 15 of the connector housing 12 and the lower portion 16 of the fitting projection 11 of the connector housing 12 which is divided into two along the flat direction. It has a structured.

そして、コネクタハウジング１２の嵌合凸部１１において、両分割ハウジング２０，３０の合体形態は、ねじ止や係合構造等により保持される。   And in the fitting convex part 11 of the connector housing 12, the united form of both the divided housings 20 and 30 is hold | maintained by screwing or an engagement structure.

また、この分割ハウジング２０，３０の互いに重ねて合体されるそれぞれの内面には、所定の回路パターンが形成されている。この回路パターンは、例えば、金属メッキ等により形成されている。このように、樹脂等の立体成型品の表面に、導電性の所定の回路パターンを形成した部品は、ＭＩＤ（Molded Interconnect Device：立体成型回路部品）と呼ばれ、上述した金属メッキ等周知の種々の方法により製造できる。   A predetermined circuit pattern is formed on each inner surface of the divided housings 20 and 30 which are combined with each other. This circuit pattern is formed by, for example, metal plating. In this way, a component in which a predetermined conductive circuit pattern is formed on the surface of a three-dimensional molded product such as a resin is called a MID (Molded Interconnect Device), and various known types such as metal plating described above are used. It can manufacture by the method of.

さらに、各分割ハウジング２０，３０の内面には、本通信機能付コネクタ装置の諸制御機能を実現するための電子部品（例えば、通信用ＩＣや負荷制御用ＩＣ等）が、その各端子を回路パターンに接続するようにして実装されている。   Furthermore, electronic parts (for example, a communication IC, a load control IC, etc.) for realizing various control functions of the connector device with communication function are provided on the inner surfaces of the divided housings 20 and 30, respectively. Implemented to connect to the pattern.

そして、第１の分割ハウジング２０を第２の分割ハウジング３０に組み付けた状態では、例えば分割ハウジング２０，３０内に配された板ばね状の金属片や、分割ハウジング２０，３０の接合部に配された異方導電部材等の仲介導電部材を通じて、両分割ハウジング２０，３０の回路パターン同士が互いに電気的に接続されることとなり、こうして本通信機能付コネクタ装置の諸制御（例えば、通信制御や負荷制御等）を行うための制御回路部が構成されている。   In the state where the first divided housing 20 is assembled to the second divided housing 30, for example, a leaf spring-shaped metal piece arranged in the divided housings 20, 30 or a joint portion of the divided housings 20, 30 is arranged. Thus, the circuit patterns of the two divided housings 20 and 30 are electrically connected to each other through the intermediate conductive member such as the anisotropic conductive member, and thus various controls (for example, communication control and A control circuit unit for performing load control and the like is configured.

防水部材１４は、例えばゴム製のリングであって、コネクタハウジング１２の嵌合凸部１１の基端部、即ち嵌合凸部１１が基部１５に接合する部分に填め込まれ、図６のように雌型コネクタ４０の嵌合孔４３に嵌合凸部１１が嵌合した際に、雌型コネクタ４０の先端部が防水部材１４に当接し、この防水部材１４自身の弾性復元力により雌型コネクタ４０との間の間隙４５が埋められて、この間隙４５が水密状に保持される。   The waterproof member 14 is, for example, a rubber ring, and is fitted into a base end portion of the fitting convex portion 11 of the connector housing 12, that is, a portion where the fitting convex portion 11 is joined to the base portion 15, as shown in FIG. When the fitting projection 11 is fitted into the fitting hole 43 of the female connector 40, the tip of the female connector 40 abuts against the waterproof member 14, and the female member 40 is elastically restored by its elastic restoring force. A gap 45 between the connector 40 and the connector 40 is filled, and the gap 45 is kept watertight.

このような通信機能付コネクタ装置１０では、分割ハウジング２０，３０の内面に回路パターンを形成すると共に電子部品を実装しているため、別途他の実装基板等を組込む必要が無く、小型化が図られるという利点がある。また、分割ハウジング２０，３０に回路パターンを形成すると共に電子部品を実装して制御回路部を構成した後、これらを合体させているため、回路パターンの形成や電子部品の実装も容易に行え、生産性に優れるという利点がある。   In such a communication function-equipped connector device 10, since the circuit pattern is formed on the inner surfaces of the divided housings 20 and 30 and the electronic components are mounted, it is not necessary to separately install another mounting board or the like, thereby reducing the size. There is an advantage that Moreover, since the circuit pattern is formed in the divided housings 20 and 30 and the electronic components are mounted to configure the control circuit portion, these are combined, so that the circuit pattern can be easily formed and the electronic components can be mounted. There is an advantage of excellent productivity.

このような通信機能付コネクタ装置１０は、例えば、次のようにして製造される。   Such a connector device 10 with a communication function is manufactured as follows, for example.

すなわち、各分割ハウジング２０，３０をモールド形成等でそれぞれ形成した後、該各分割ハウジング２０，３０の内面に金属メッキ等で回路パターン及び接続端子部を形成し、さらに、各電子部品を実装する。また、分割ハウジング２０，３０に対して端子部の組み込みや接続ケーブル４の組み込みを行う。そして、両分割ハウジング２０，３０の対向面間に板ばね状の金属片や異方導電部材等の仲介導電部材を挟込むようにして、両分割ハウジング２０，３０を合体させると、内部に制御回路部が構成された通信機能付コネクタ装置１０の組立てが完了する。   That is, after the divided housings 20 and 30 are formed by molding or the like, circuit patterns and connection terminal portions are formed on the inner surfaces of the divided housings 20 and 30 by metal plating or the like, and each electronic component is mounted. . Further, the terminal portion and the connection cable 4 are assembled into the divided housings 20 and 30. Then, when both the divided housings 20 and 30 are combined with each other such that an intermediate conductive member such as a leaf spring-like metal piece or an anisotropic conductive member is sandwiched between the opposed surfaces of the both divided housings 20 and 30, the control circuit unit is incorporated therein. The assembly of the connector device 10 with communication function configured as described above is completed.

このように構成された通信機能付コネクタ装置１０によると、各分割ハウジング２０，３０の内部に、制御回路部を容易に構成しつつ、その小型化を図ることができる。   According to the connector device 10 with a communication function configured as described above, the control circuit unit can be easily configured in each of the divided housings 20 and 30, and the size can be reduced.

また、両分割ハウジング２０，３０同士の接続について、両分割ハウジング２０，３０同士を重ね合わせるだけで、容易に制御回路部を構成できる。   Moreover, about the connection of both the divided housings 20 and 30, a control circuit part can be easily comprised only by superimposing both the divided housings 20 and 30.

次に、この実施の形態の理解を容易にするための比較例について説明する。図７は、通信機能付コネクタ装置１０のコネクタハウジング１２の分割ハウジング２０，３０の接合部分が、嵌合凸部１１だけでなく基部１５にまで到達している比較例を示す斜視図、図８は同じくその側面図である。   Next, a comparative example for facilitating understanding of this embodiment will be described. FIG. 7 is a perspective view showing a comparative example in which the joint portion of the split housings 20 and 30 of the connector housing 12 of the connector device 10 with a communication function reaches not only the fitting convex portion 11 but also the base portion 15. Is a side view of the same.

図７及び図８に示した通信機能付コネクタ装置１０において、図５及び図６に示したような雌型コネクタ４０の嵌合孔４３内に嵌入されるのは、嵌合凸部１１のみである。したがって、コネクタハウジング１２の基部１５は、雌型コネクタ４０（図５及び図６参照）の嵌合孔４３からはみ出ることになり、よって基部１５は防水機能を付与しにくい部分となる。しかしながら、両分割ハウジング２０，３０の形状を図７及び図８のように設定する場合、両分割ハウジング２０，３０同士の接合部分が嵌合凸部１１だけでなく基部１５にまで到達しているため、雌型コネクタ４０（図５及び図６参照）の嵌合孔４３内に嵌合凸部１１を嵌入しても、両分割ハウジング２０，３０同士の基部１５における接合部分が、雌型コネクタ４０の嵌合孔４３からはみ出してしまい、外部の浸水に晒され易くなる。   In the connector device 10 with a communication function shown in FIGS. 7 and 8, only the fitting convex portion 11 is inserted into the fitting hole 43 of the female connector 40 as shown in FIGS. is there. Therefore, the base portion 15 of the connector housing 12 protrudes from the fitting hole 43 of the female connector 40 (see FIGS. 5 and 6), and thus the base portion 15 is a portion that is difficult to provide a waterproof function. However, when the shapes of the two divided housings 20 and 30 are set as shown in FIGS. 7 and 8, the joint portion between the two divided housings 20 and 30 reaches not only the fitting convex portion 11 but also the base portion 15. Therefore, even if the fitting convex portion 11 is inserted into the fitting hole 43 of the female connector 40 (see FIGS. 5 and 6), the joint portion at the base portion 15 between the two divided housings 20 and 30 is the female connector. It protrudes from the fitting hole 43 of 40, and becomes easy to be exposed to external water immersion.

これに対して、図３〜図６に示した実施の形態の通信機能付コネクタ装置１０では、両分割ハウジング２０，３０同士の接合部分が、嵌合凸部１１部分に限定されており、雌型コネクタ４０の嵌合孔４３からはみ出したコネクタハウジング１２の基部１５においては、両分割ハウジング２０，３０同士の接合部分が存在していない。即ち、両分割ハウジング２０，３０同士の接合部分は、防水機能を付与しにくい基部１５の部分に位置することなく、雌型コネクタ４０の嵌合孔４３の内部に嵌入される。そして、嵌合凸部１１が雌型コネクタ４０の嵌合孔４３内に嵌入される際には、雌型コネクタ４０の先端部が防水部材１４に当接し、この防水部材１４自身の弾性復元力により雌型コネクタ４０との間の間隙４５が埋められて、この間隙４５が水密状に保持される。したがって、雌型コネクタ４０の嵌合孔４３内に位置するコネクタハウジング１２の嵌合凸部１１が浸水に晒されるのを防止でき、両分割ハウジング２０，３０同士の接合部分の防水機能を確実に確保できる。   On the other hand, in the connector device 10 with a communication function of the embodiment shown in FIGS. 3 to 6, the joint portion between the two divided housings 20 and 30 is limited to the fitting convex portion 11, and the female In the base portion 15 of the connector housing 12 that protrudes from the fitting hole 43 of the mold connector 40, there is no joint portion between the two divided housings 20 and 30. That is, the joint portion between the two divided housings 20 and 30 is fitted into the fitting hole 43 of the female connector 40 without being positioned at the portion of the base portion 15 where it is difficult to provide a waterproof function. When the fitting projection 11 is inserted into the fitting hole 43 of the female connector 40, the tip of the female connector 40 abuts against the waterproof member 14, and the elastic restoring force of the waterproof member 14 itself is obtained. As a result, a gap 45 between the female connector 40 and the female connector 40 is filled, and the gap 45 is held in a watertight manner. Therefore, the fitting convex portion 11 of the connector housing 12 positioned in the fitting hole 43 of the female connector 40 can be prevented from being exposed to water, and the waterproof function of the joint portion between the two divided housings 20 and 30 can be ensured. It can be secured.

このことは、両分割ハウジング２０，３０同士の接合面に、絶縁樹脂等で封止するなどの特別の防水部材等を設置することなく、この接合面の防水機能が確保されることを意味している。したがって、両分割ハウジング２０，３０同士の接合面を簡素な構造で防水機能を付与することが可能となる。   This means that the waterproof function of the joint surface is ensured without installing a special waterproof member such as sealing with insulating resin or the like on the joint surface between the split housings 20 and 30. ing. Therefore, it becomes possible to provide a waterproof function with a simple structure at the joint surface between the two divided housings 20 and 30.

尚、上記実施の形態では、コネクタハウジング１２を、第１及び第２の分割ハウジング２０，３０といった２つの部材で構成していたが、これらの内部の回路パターン等を嵌合凸部１１でのみ接続を行って接合する構成であれば、３つ以上の部材で構成しても差し支えない。   In the above-described embodiment, the connector housing 12 is constituted by two members such as the first and second divided housings 20 and 30. If it is the structure which connects and joins, even if it comprises with three or more members, it does not interfere.
