The present invention relates to a connector device.
複数の比較的細いケーブルを、各種の電気回路部品が取り付けられる回路基板に接続するにあたっては、回路基板に電気的接続がなされて取り付けられる基板側コネクタと、複数のケーブルが電気的に接続されたもとで基板側コネクタに連結されるケーブル側コネクタとが用いられる。ケーブル側コネクタには、複数のケーブルとの電気的接続がなされる複数の導電コンタクトが配された差込部が設けられる。また、基板側コネクタには、ケーブル側コネクタに設けられた差込部が挿入される嵌合部が設けられ、さらに、回路基板との電気的接続がなされたもとで、嵌合部内においてケーブル側コネクタの差込部における複数の導電コンタクトに夫々押圧接触する、複数の導電コンタクトが配される。 When connecting a plurality of relatively thin cables to a circuit board to which various electrical circuit components are mounted, a board-side connector that is mounted by being electrically connected to the circuit board and a plurality of cables are electrically connected. And a cable-side connector connected to the board-side connector. The cable-side connector is provided with an insertion portion in which a plurality of conductive contacts that are electrically connected to a plurality of cables are arranged. The board-side connector is provided with a fitting portion into which the insertion portion provided in the cable-side connector is inserted, and further, the cable-side connector is connected to the circuit board in the fitting portion. A plurality of conductive contacts that are in press contact with the plurality of conductive contacts in the plug-in portion are arranged.
基板側コネクタは、嵌合部を形成するとともに複数の導電コンタクトを支持する絶縁ハウジングと、外部からの電磁波ノイズ対策のため、即ち、外部からの電磁波ノイズに対するシールド効果を得るため、絶縁ハウジングを部分的もしくは全体的に覆ってグラウンド接続される、金属製の導電性シェルとを備えて構成される。また、ケーブル側コネクタは、差込部を形成するとともに複数の導電コンタクトを支持する絶縁ハウジングと、外部からの電磁波ノイズ対策のため、即ち、外部からの電磁波ノイズに対するシールド効果を得るため、絶縁ハウジングを部分的もしくは全体的に覆ってグラウンド接続される、金属製の導電性シェルとを備えて構成される。そして、ケーブル側コネクタは、複数の導電コンタクトに複数のケーブルが電気的に接続されたもとで、差込部が基板側コネクタの嵌合部に挿入されて、基板側コネクタに連結される。その際、差込部における複数の導電コンタクトに基板側コネクタの複数の導電コンタクトが夫々押圧接触するものとされ、それにより、ケーブル側コネクタに接続された複数のケーブルと基板側コネクタが取り付けられた回路基板との電気的接続がなされる。 The board-side connector includes an insulating housing that forms a fitting portion and supports a plurality of conductive contacts, and a part of the insulating housing to prevent external electromagnetic noise, that is, to obtain a shielding effect against external electromagnetic noise. And a metal conductive shell that is grounded or entirely covered and connected to the ground. In addition, the cable-side connector includes an insulating housing that forms an insertion part and supports a plurality of conductive contacts, and an insulating housing for countermeasures against external electromagnetic noise, that is, to obtain a shielding effect against external electromagnetic noise. And a metal conductive shell that is partially or entirely covered and grounded. The cable-side connector is connected to the board-side connector by inserting the plug-in part into the fitting part of the board-side connector while the plurality of cables are electrically connected to the plurality of conductive contacts. At that time, the plurality of conductive contacts of the board-side connector are in press contact with the plurality of conductive contacts in the insertion portion, respectively, thereby attaching the plurality of cables connected to the cable-side connector and the board-side connector. Electrical connection with the circuit board is made.
このようにして、ケーブル側コネクタが基板側コネクタに連結されるとき、基板側コネクタにおける導電性シェルにケーブル側コネクタにおける導電性シェルが係合し、それにより、両導電性シェルがグラウンド接続されるとともに、基板側コネクタに対するケーブル側コネクタの連結状態が維持される。そのため、基板側コネクタにおける導電性シェルに対するケーブル側コネクタにおける導電性シェルの係合は、確実かつ堅固に、しかも、容易に行われることが望まれ、従来にあっては、基板側コネクタにおける導電性シェル及びケーブル側コネクタにおける導電性シェルの両者に、斯かる要望に応えることを意図した係止機構を設けることが提案されている（例えば、特許文献１参照。）。 In this way, when the cable side connector is coupled to the board side connector, the conductive shell of the cable side connector is engaged with the conductive shell of the board side connector, thereby connecting both the conductive shells to the ground. At the same time, the connection state of the cable side connector to the board side connector is maintained. For this reason, it is desirable that the conductive shell in the cable-side connector engages with the conductive shell in the board-side connector reliably, firmly, and easily. It has been proposed that both the shell and the conductive shell in the cable-side connector are provided with a locking mechanism intended to meet such a demand (see, for example, Patent Document 1).
斯かる従来提案されている係止機構を備えたコネクタ装置にあっては、基板側コネクタの絶縁ハウジングを覆う導電性シェルである基板側コネクタシールドシェルの側壁部に係止部が設けられるとともに、ケーブル側コネクタの絶縁ハウジングを覆う導電性シェルであるケーブル側コネクタシールドシェルにおける、基板側コネクタとの連結時に基板側コネクタシールドシェルの側壁部に対向することになる側壁部に、被係止部を有した係合アームが設けられる。そして、ケーブル側コネクタが基板側コネクタに連結されるとき、ケーブル側コネクタシールドシェルの側壁部に設けられた係合アームが、基板側コネクタシールドシェルの側壁部に対接して、それにおける被係止部が基板側コネクタシールドシェルの側壁部に設けられた係止部に係合して係止され、それにより係合アーム全体が係止部によって係止される。 In the connector device having such a conventionally proposed locking mechanism, a locking portion is provided on the side wall portion of the board-side connector shield shell, which is a conductive shell covering the insulating housing of the board-side connector, In the cable-side connector shield shell, which is a conductive shell that covers the insulating housing of the cable-side connector, a locked portion is provided on the side wall portion that faces the side wall portion of the board-side connector shield shell when connected to the board-side connector. An engaging arm is provided. When the cable-side connector is connected to the board-side connector, the engagement arm provided on the side wall of the cable-side connector shield shell comes into contact with the side wall of the board-side connector shield shell and is locked there The portion is engaged and locked with a locking portion provided on the side wall portion of the board-side connector shield shell, whereby the entire engaging arm is locked by the locking portion.
このようにして、ケーブル側コネクタシールドシェルの側壁部に設けられた係合アームが基板側コネクタシールドシェルの側壁部に設けられた係止部により係止されることにより、ケーブル側コネクタシールドシェルが基板側コネクタシールドシェルに係合して、両シールドシェルがグラウンド接続されるとともに、基板側コネクタに対するケーブル側コネクタの連結状態が維持される。 In this way, the engagement arm provided on the side wall portion of the cable side connector shield shell is locked by the locking portion provided on the side wall portion of the board side connector shield shell, so that the cable side connector shield shell is Both the shield shells are grounded by engaging with the board-side connector shield shell, and the connection state of the cable-side connector to the board-side connector is maintained.
上述のように、基板側コネクタシールドシェルの側壁部に係止部が設けられるとともに、ケーブル側コネクタシールドシェルの側壁部に被係止部を有した係合アームが設けられ、ケーブル側コネクタが基板側コネクタに連結されるとき、係合アームにおける被係止部が係止部に係合して係止され、それにより係合アームが基板側コネクタシールドシェルの側壁部に対接する状態におかれることになる係止機構を備えた従来のコネクタ装置にあっては、ケーブル側コネクタの基板側コネクタに対する連結時に、ケーブル側コネクタシールドシェルの側壁部に設けられた係合アームとそれが対接する基板側コネクタシールドシェルの側壁部との間に、微細な塵埃等が挟まってしまう虞がある。また、ケーブル側コネクタの基板側コネクタに対する着脱回数が重ねられると、その虞が高まっていき、一旦、係合アームと基板側コネクタシールドシェルの側壁部との間に塵埃等が挟まってしまうと、そのことが気付かれ難く、当該塵埃等が取り去られるということは考えに難い。 As described above, the locking portion is provided on the side wall portion of the board-side connector shield shell, the engaging arm having the locked portion is provided on the side wall portion of the cable-side connector shield shell, and the cable-side connector is mounted on the board. When connected to the side connector, the locked portion of the engagement arm engages and locks with the locking portion, thereby placing the engagement arm in contact with the side wall portion of the board-side connector shield shell. In the conventional connector device provided with the locking mechanism to be different, when the cable side connector is connected to the board side connector, the engagement arm provided on the side wall portion of the cable side connector shield shell and the board to which it contacts There is a risk that fine dust or the like may be caught between the side connector shield shell and the side wall. In addition, when the number of times the cable side connector is attached to and detached from the board side connector is increased, the risk increases, and once dust or the like is caught between the engagement arm and the side wall portion of the board side connector shield shell, This is difficult to notice and it is difficult to think that the dust or the like is removed.
そして、係合アームと基板側コネクタシールドシェルの側壁部との間に塵埃等が挟まってしまう事態が生じると、基板側コネクタシールドシェルと係合アームが設けられたケーブル側コネクタシールドシェルとの相互接触が不良となり、両者の電気的接続状態が良好でなくなってしまう。その結果、基板側コネクタシールドシェルとケーブル側コネクタシールドシェルとのグラウンド接続が良好でなくなり、両シールドシェルによる基板側コネクタとケーブル側コネクタとについての外部からの電磁波ノイズに対するシールド効果が、適正に得られなくなってしまうという問題が生じる。 When dust or the like is caught between the engagement arm and the side wall of the board-side connector shield shell, the board-side connector shield shell and the cable-side connector shield shell provided with the engagement arm are mutually connected. The contact is poor, and the electrical connection between the two is not good. As a result, the ground connection between the board-side connector shield shell and the cable-side connector shield shell is not good, and the shield effect against external electromagnetic noise on the board-side connector and the cable-side connector by both shield shells is properly obtained. There is a problem that it becomes impossible.
斯かる点に鑑み、本願の特許請求の範囲に記載された発明は、回路基板に電気的に接続されて取り付けられる基板側コネクタと複数のケーブルが電気的に接続されたもとで基板側コネクタに連結されるケーブル側コネクタとを含んで構成され、ケーブル側コネクタが基板側コネクタに連結されるとき、基板側コネクタにおける導電性シェルに対するケーブル側コネクタにおける導電性シェルの係合が、両シェルの相互接触が不良となって両シェルについてのグラウンド接続が良好でなくなる事態の発生を回避できる構造をもって、確実かつ堅固に、しかも、容易に行われることになるコネクタ装置を提供する。 In view of this, the invention described in the claims of the present application is coupled to the board-side connector while the board-side connector and the plurality of cables that are electrically connected to the circuit board are electrically connected. When the cable-side connector is connected to the board-side connector, the engagement of the conductive shell in the cable-side connector with the conductive shell in the board-side connector causes the mutual contact of both shells. A connector device which can be reliably, firmly and easily performed with a structure capable of avoiding the occurrence of a situation in which the ground connection of both shells is not good due to failure of the shell.

上述のように構成される本発明に係るコネクタ装置にあっては、基板側コネクタが備える第１の導電性シェル及びケーブル側コネクタが備える第２の導電性シェルが、第１の導電性シェルに押圧接触部が設けられるとともに第２の導電性シェルに受圧接触部が設けられるもの、もしくは、第１の導電性シェルに受圧接触部が設けられるとともに第２の導電性シェルに押圧接触部が設けられるものとされる。そして、ケーブル側コネクタが、基板側コネクタに対してそれに向かう第１の方向に相対移動せしめられて当該基板側コネクタに連結されるとき、第１の導電性シェルもしくは第２の導電性シェルに設けられた押圧接触部が、第２の導電性シェルもしくは第１の導電性シェルに設けられた受圧接触部に、第１の方向に直交する第２の方向の押圧力を作用させて当接し、さらに、第２の導電性シェルに設けられた受圧接触部もしくは押圧接触部が、第１及び第２の方向の夫々に直交する第３の方向の弾性変位を生じて、第１の導電性シェルに係合する。 In the connector device according to the present invention configured as described above, the first conductive shell included in the board-side connector and the second conductive shell included in the cable-side connector are used as the first conductive shell. A pressure contact portion is provided on the second conductive shell and a pressure contact portion is provided on the first conductive shell and a pressure contact portion is provided on the second conductive shell. It is supposed to be. When the cable side connector is moved relative to the board side connector in the first direction toward the board side connector and connected to the board side connector, the cable side connector is provided in the first conductive shell or the second conductive shell.

Engage with.
このような第１の導電性シェルに対する第２の導電性シェルに設けられた受圧接触部もしくは押圧接触部の係合は、例えば、第１の導電性シェルに第１の係合部が設けられるとともに、第２の導電性シェルに設けられた受圧接触部もしくは押圧接触部に第２の係合部が設けられ、ケーブル側コネクタが基板側コネクタに連結されるとき、第１の係合部が第２の係合部を係止することにより行われる。それにより、第２の導電性シェルが第１の導電性シェルと係合した状態を維持する状態におかれる。 As for the engagement of the pressure receiving contact portion or the pressing contact portion provided on the second conductive shell with respect to the first conductive shell, for example, the first engagement portion is provided on the first conductive shell. In addition, when the second engagement portion is provided in the pressure receiving contact portion or the pressing contact portion provided in the second conductive shell, and the cable side connector is connected to the board side connector, the first engagement portion is This is done by locking the second engaging portion. As a result, the second conductive shell is kept in a state of being engaged with the first conductive shell.
上述の本発明に係るコネクタ装置にあっては、ケーブル側コネクタが基板側コネクタに連結されるとき、第１の導電性シェルもしくは第２の導電性シェルに設けられた押圧接触部が、第２の導電性シェルもしくは第１の導電性シェルに設けられた受圧接触部に押圧力を作用させて当接するとともに、第２の導電性シェルに設けられた受圧接触部もしくは押圧接触部が弾性変位を生じて第１の導電性シェルに係合し、それによって、第２の導電性シェルが第１の導電性シェルとの係合を維持する状態におかれる。そのため、ケーブル側コネクタが基板側コネクタに向かう方向に移動せしめられて当該基板側コネクタに連結される際における、基板側コネクタが備える第１の導電性シェルに対するケーブル側コネクタが備える第２の導電性シェルの係合が、確実かつ堅固に行われ、しかも、ケーブル側コネクタを基板側コネクタに対してそれに向かう方向に相対移動させるだけの簡単な操作により容易に行われる。 In the connector device according to the present invention described above, when the cable-side connector is connected to the board-side connector, the pressing contact portion provided on the first conductive shell or the second conductive shell is the second The pressure receiving contact portion provided on the second conductive shell is brought into contact with the pressure receiving contact portion provided on the conductive shell or the first conductive shell by applying a pressing force. Occurs and engages the first conductive shell, thereby placing the second conductive shell in engagement with the first conductive shell. Therefore, when the cable-side connector is moved in the direction toward the board-side connector and connected to the board-side connector, the second conductivity of the cable-side connector with respect to the first conductive shell of the board-side connector is provided. Engagement of the shell is performed reliably and firmly, and is easily performed by a simple operation of moving the cable side connector relative to the board side connector in the direction toward it.
それに加えて、ケーブル側コネクタが基板側コネクタに連結されるべく当該基板側コネクタに向かって移動せしめられる方向が第１の方向とされるもとで、第１の導電性シェルもしくは第２の導電性シェルに設けられた押圧接触部が、第２の導電性シェルもしくは第１の導電性シェルに設けられた受圧接触部に、第１の方向に直交する第２の方向の押圧力を作用させて当接し、さらに、第２の導電性シェルに設けられた受圧接触部もしくは押圧接触部が、第１及び第２の方向の夫々に直交する第３の方向の弾性変位を生じて、第１の導電性シェルに係合する。それにより、ケーブル側コネクタが基板側コネクタに連結されるべく当該基板側コネクタに向かって第１の方向に移動せしめられるとき、受圧接触部とそれに第２の方向の押圧力を作用させて当接する押圧接触部とは、互いに直交する第１の方向及び第３の方向の二方向における相対摺動を行って相互接触するものとなる。従って、受圧接触部と押圧接触部とにあっては、たとえ、いずれか一方あるいは両者の接触面部に微細な塵埃等が付着したとしても、それが両者の相対摺動により除去されて、両者の間に微細な塵埃等が挟まってしまうことがなく、ケーブル側コネクタの基板側コネクタに対する着脱回数が重ねられても、両者の相互接触が良好なものとされる。 In addition, the first conductive shell or the second conductive member can be used in such a manner that the direction in which the cable side connector is moved toward the board side connector to be connected to the board side connector is the first direction.

Furthermore, the pressure receiving contact portion or the pressing contact portion provided on the second conductive shell causes elastic displacement in a third direction orthogonal to the first and second directions, and Engage with the conductive shell. Accordingly, when the cable side connector is moved in the first direction toward the board side connector to be connected to the board side connector, the pressure receiving contact portion and the pressing force in the second direction are applied to contact with the pressure receiving contact portion. The pressing contact portion is a member that makes mutual contact in two directions of a first direction and a third direction orthogonal to each other. Therefore, in the pressure receiving contact portion and the pressing contact portion, even if fine dust or the like adheres to either one or both contact surface portions, it is removed by the relative sliding of both, Fine dust or the like is not sandwiched between them, and even if the cable-side connector is attached to and detached from the board-side connector, the mutual contact between them is good.
その結果、第１の導電性シェルを備えた基板側コネクタに第２の導電性シェルを備えたケーブル側コネクタが連結されたもとにおいて、押圧接触部もしくは受圧接触部が設けられた第１の導電性シェルと受圧接触部もしくは押圧接触部が設けられた第２の導電性シェルとについてのグラウンド接続が良好でなくなる事態の発生を回避できることになる。そして、それに伴い、第１の導電性シェル及び第２の導電性シェルによる、基板側コネクタ及びケーブル側コネクタについての外部からの電磁波ノイズに対するシールド効果が、適正に得られなくなってしまうという問題は生じない。 As a result, when the cable-side connector having the second conductive shell is coupled to the board-side connector having the first conductive shell, the first conductive having the pressing contact portion or the pressure receiving contact portion is provided. Occurrence of a situation in which the ground connection between the shell and the second conductive shell provided with the pressure receiving contact portion or the pressing contact portion is not good can be avoided. Accordingly, there arises a problem that the shielding effect against the electromagnetic wave noise from the outside of the board side connector and the cable side connector by the first conductive shell and the second conductive shell cannot be obtained properly. Absent.
