Description

本発明は、基板搭載型シールドコネクタに関する。   The present invention relates to a board-mounted shield connector.

図１７は、下記特許文献１に開示された基板搭載型シールドコネクタを示している。
この基板搭載型シールドコネクタ１００は、装置ケース１１０の底部に配置されるプリント回路基板１２０に搭載されるコネクタで、絶縁ハウジング１４０と、シールドケース１５０と、を備えている。 FIG. 17 shows a board-mounted shield connector disclosed in Patent Document 1 below.
The board-mounted shield connector 100 is a connector mounted on a printed circuit board 120 disposed at the bottom of the apparatus case 110 and includes an insulating housing 140 and a shield case 150.

プリント回路基板１２０は、基板搭載型シールドコネクタ１００を搭載した状態で、図１７の矢印Ｘ１方向に沿って装置ケース１１０内に挿入される。装置ケース１１０に挿入されたプリント回路基板１２０は、基板上の取付孔１２１の位置が装置ケース１１０の底壁１１１に配置された基板支持支柱１１２の位置に整合したら、基板支持支柱１１２の雌ねじ部１１２ａと螺合するネジ部材１６０により基板支持支柱１１２に固定される。   The printed circuit board 120 is inserted into the apparatus case 110 along the arrow X1 direction of FIG. 17 in a state where the board-mounted shield connector 100 is mounted. When the position of the mounting hole 121 on the printed circuit board 120 inserted into the device case 110 is aligned with the position of the substrate support column 112 disposed on the bottom wall 111 of the device case 110, the female thread portion of the substrate support column 112 is provided. It is fixed to the substrate support column 112 by a screw member 160 which is screwed with the 112a.

絶縁ハウジング１４０は、プリント回路基板１２０にハンダ付けされる複数の基板接続端子１４１を収容保持している。絶縁ハウジング１４０に収容保持されている基板接続端子１４１は、プリント回路基板１２０に形成されているスルーホールに挿通された後、スルーホールの周囲に形成されている導体箔（接点パターン）に半田付けされる。   The insulating housing 140 accommodates and holds a plurality of board connection terminals 141 to be soldered to the printed circuit board 120. The board connection terminal 141 accommodated and held in the insulating housing 140 is inserted into a through hole formed in the printed circuit board 120 and then soldered to a conductor foil (contact pattern) formed around the through hole. Is done.

シールドケース１５０は、金属板のプレス加工により、絶縁ハウジング１４０に被嵌装着可能な略箱型に成形されている。このシールドケース１５０は、外壁部に、切り起こしによって、接地端子１５１が形成されている。この接地端子１５１は、プリント回路基板１２０に形成されているスルーホールに挿通された後、スルーホールの周囲に形成されている導体箔（接点パターン）に半田付けされることで、プリント回路基板１２０に形成されているアース回路に導通接続される。   The shield case 150 is formed into a substantially box shape that can be fitted and attached to the insulating housing 140 by pressing a metal plate.

特開平８−２５５６５７号公報JP-A-8-255657

ところで、図１７に示した従来例の場合は、基板搭載型シールドコネクタ１００が、離間距離を開けずに、プリント回路基板１２０の表面に直に載置される構造である。   In the case of the conventional example shown in FIG. 17, the board-mounted shield connector 100 is directly mounted on the surface of the printed circuit board 120 without leaving a separation distance.

そのため、シールドケース１５０に延出させる接地端子１５１は、延出長（突出長）が短くとも、プリント回路基板１２０のスルーホールに挿通させることができ、半田付け作業も難しくない。   Therefore, the ground terminal 151 extended to the shield case 150 can be inserted into the through hole of the printed circuit board 120 even if the extension length (projection length) is short, and the soldering operation is not difficult.

しかし、装置によっては、装置ケース１１０内における他のデバイス等の配置上の制約等から、プリント回路基板１２０と基板搭載型シールドコネクタ１００との間に離間距離が発生すると共に、その離間距離が大きくなってしまう場合もある。   However, depending on the apparatus, a separation distance is generated between the printed circuit board 120 and the board-mounted shield connector 100 due to restrictions on arrangement of other devices in the apparatus case 110, and the separation distance is large. Sometimes it becomes.

そのような場合には、離間距離の分だけ、接地端子１５１の延出長を増大させる必要がある。しかし、一般的に、シールドケース１５０は、軽量化等の目的から、使用する金属板の薄肉化が重要課題とされている。そのため、接地端子１５１の延出長が増大すると、強度不足によって接地端子１５１に曲げ変形が生じ易くなり、接地端子１５１の曲げ変形によって、プリント回路基板１２０上のスルーホールへの挿通が難しくなったり、或いは、接地端子１５１の折損といった問題が発生するおそれがあった。   In such a case, it is necessary to increase the extension length of the ground terminal 151 by the distance. However, in general, for the shield case 150, for the purpose of reducing the weight or the like, it is important to reduce the thickness of the metal plate to be used. Therefore, when the extension length of the ground terminal 151 increases, the ground terminal 151 is likely to be bent due to insufficient strength, and the bending deformation of the ground terminal 151 makes it difficult to insert into the through hole on the printed circuit board 120. Alternatively, a problem such as breakage of the ground terminal 151 may occur.

また、接地端子１５１は、幅の狭い端子であるため、単純な平板状の構造では、半田付けの際に、半田の乗り（濡れ性）が悪く、安定した半田付け作業が難しいという問題もあった。   In addition, since the ground terminal 151 is a narrow terminal, the simple flat plate structure has a problem that soldering (wetting) is poor during soldering, and stable soldering work is difficult. It was.

そこで、本発明の目的は、上記課題を解消することに係り、プリント回路基板と基板搭載型シールドコネクタとの間の離間距離が大きく、シールドケースに切り起こし形成する接地端子の延出長が増大する場合でも、プリント回路基板への接続時に前記接地端子に接続の妨げとなる変形が発生し難く、また、接地端子における半田の乗り（濡れ性）を向上させて接地端子における半田付け性を向上させることもでき、プリント回路基板への接続作業を容易にすることのできる基板搭載型シールドコネクタを提供することにある。   Accordingly, an object of the present invention is to solve the above-mentioned problems, and the separation distance between the printed circuit board and the board-mounted shield connector is large, and the extension length of the ground terminal formed by cutting and raising the shield case is increased. Even when connecting to a printed circuit board, it is difficult for the ground terminal to be deformed to prevent connection, and soldering (wetting) on the ground terminal is improved to improve solderability on the ground terminal. Another object of the present invention is to provide a board-mounted shield connector that can be easily connected to a printed circuit board.

本発明の前述した目的は、下記の構成により達成される。
（１） プリント回路基板にハンダ付けされる基板接続端子を収容保持した絶縁ハウジングと、
金属板のプレス加工により前記絶縁ハウジングに被嵌装着可能な略箱型に成形されると共に、外壁部には前記プリント回路基板にハンダ付けされる接地端子が切り起こしにより形成され、被嵌装着された前記絶縁ハウジングの外周囲を電磁遮蔽するシールドケースと、
を備える基板搭載型シールドコネクタであって、
前記接地端子は、折曲加工によって、前記接地端子の延出方向に沿って延在する稜線部が形成されていることを特徴とする基板搭載型シールドコネクタ。 The above-described object of the present invention is achieved by the following configuration.
(1) an insulating housing that houses and holds board connection terminals to be soldered to the printed circuit board;
It is formed into a substantially box shape that can be fitted and attached to the insulating housing by pressing a metal plate, and a ground terminal soldered to the printed circuit board is formed on the outer wall by cutting and fitting. A shield case for electromagnetically shielding the outer periphery of the insulating housing;
A board-mounted shielded connector comprising:
The board-mounted shield connector, wherein the ground terminal is formed with a ridge line portion extending along the extending direction of the ground terminal by bending.

（２） 前記接地端子の根本側は、前記稜線部が形成されず、平板状構造を維持したフラット部に形成され、
前記絶縁ハウジングには、前記シールドケースを被嵌装着させた際に前記フラット部に嵌合して前記フラット部を補強する端子根本補強部を備えたことを特徴とする上記（１）に記載の基板搭載型シールドコネクタ。 (2) The root side of the ground terminal is formed in a flat portion that maintains the flat structure without the ridge line portion being formed,
The insulating housing includes a terminal base reinforcing portion that fits into the flat portion and reinforces the flat portion when the shield case is fitted and attached. Board-mounted shield connector.

上記（１）の構成によれば、シールドケースに形成される接地端子は、端子の延出方向に沿って延在する稜線部が形成されたことで、曲げ剛性が向上する。そのため、プリント回路基板と基板搭載型シールドコネクタとの間の離間距離が大きく、シールドケースに切り起こし形成する接地端子の延出長が増大する場合でも、プリント回路基板への接続時に、前記接地端子に接続の妨げとなる変形が発生し難くなる。従って、プリント回路基板のスルーホールへ接地端子を挿通させる作業も、容易になる。   According to the configuration of (1) above, the ground terminal formed in the shield case has the ridge line portion extending along the extending direction of the terminal, so that the bending rigidity is improved. Therefore, even when the distance between the printed circuit board and the board-mounted shield connector is large and the extension length of the ground terminal formed by cutting and raising the shield case is increased, the ground terminal is connected to the printed circuit board. It is difficult for deformation to hinder connection. Therefore, the operation of inserting the ground terminal into the through hole of the printed circuit board is also facilitated.

また、接地端子は、稜線部を形成する折曲加工によって、稜線部の無い単純な平板構造の場合と比較すると半田付けの際に半田の乗り（濡れ性）が良くなるため、接地端子における半田付け性を向上させることもできる。   In addition, since the ground terminal is bent to form the ridge line portion, soldering (wetting) is improved during soldering compared to the case of a simple flat plate structure without the ridge line portion. It is also possible to improve the attachment.

従って、基板搭載型シールドコネクタのプリント回路基板への接続作業を容易にすることができる。   Therefore, the connection work of the board-mounted shield connector to the printed circuit board can be facilitated.

上記（２）の構成によれば、接地端子の根本側は平板状構造を維持しているため、根本まで稜線部を形成する場合と比較すると、稜線部を形成する曲げ加工の施工が容易になり、シールドケースの加工性、生産性を向上させることができる。   According to the configuration of (2) above, since the base side of the ground terminal maintains a flat plate structure, it is easier to perform bending work to form the ridge line part than when forming the ridge line part to the root. Thus, the processability and productivity of the shield case can be improved.

また、接続端子の平板状の根本側は、絶縁ハウジングに装備された端子根本補強部によって補強されるため、接地端子の根本側を平板状にしていても、接地端子には曲げ変形が発生し難く、プリント回路基板のスルーホールへ接地端子を挿通させる作業が容易な長所を残すことができる。   In addition, since the flat base side of the connection terminal is reinforced by the terminal base reinforcement provided on the insulating housing, even if the base side of the ground terminal is flat, the ground terminal is bent and deformed. It is difficult to leave the advantage that the work of inserting the ground terminal into the through hole of the printed circuit board is easy.

本発明による基板搭載型シールドコネクタによれば、シールドケースに形成される接地端子は、端子の延出方向に沿って延在する稜線部が形成されたことで、曲げ剛性が向上する。そのため、プリント回路基板と基板搭載型シールドコネクタとの間の離間距離が大きく、シールドケースに切り起こし形成する接地端子の延出長が増大する場合でも、プリント回路基板への接続時に前記接地端子に接続の妨げとなる変形が発生し難くなる。従って、プリント回路基板のスルーホールへ接地端子を挿通させる作業も、容易になる。   According to the board-mounted shield connector of the present invention, the bending rigidity of the ground terminal formed in the shield case is improved by forming the ridge line portion extending along the extending direction of the terminal. Therefore, even when the distance between the printed circuit board and the board-mounted shield connector is large and the extension length of the ground terminal formed by cutting and raising the shield case is increased, the ground terminal is connected to the printed circuit board. Deformation that hinders connection is less likely to occur. Therefore, the operation of inserting the ground terminal into the through hole of the printed circuit board is also facilitated.

また、接地端子は、稜線部を形成する折曲加工によって、稜線部の無い単純な平板構造の場合と比較すると半田付けの際に半田の乗り（濡れ性）が良くなるため、接地端子における半田付け性を向上させることもできる。   In addition, since the ground terminal is bent to form the ridge line portion, soldering (wetting) is improved during soldering compared to the case of a simple flat plate structure without the ridge line portion. It is also possible to improve the attachment.

従って、基板搭載型シールドコネクタのプリント回路基板への接続作業を容易にすることができる。   Therefore, the connection work of the board-mounted shield connector to the printed circuit board can be facilitated.

なお、基板接続端子２２，２３及び接地端子３５，３６の先端部がプリント回路基板４０のスルーホール４２，４３，４５，４６に挿通したときには、図１０に示すように、プリント回路基板４０のコネクタ係止孔４８に、絶縁ハウジング２０に装備された基板係止突起２８が係合して、プリント回路基板４０と絶縁ハウジング２０とが連結状態になる。   When the tip ends of the board connection terminals 22 and 23 and the ground terminals 35 and 36 are inserted into the through holes 42, 43, 45, and 46 of the printed circuit board 40, as shown in FIG. The board locking protrusions 28 mounted on the insulating housing 20 are engaged with the locking holes 48, and the printed circuit board 40 and the insulating housing 20 are connected.

以上に説明した第１実施形態の基板搭載型シールドコネクタ１の場合、シールドケース３０に形成される接地端子３５，３６は、端子の延出方向に沿って延在する稜線部３５１，３６１が形成されたことで、曲げ剛性が向上する。そのため、プリント回路基板４０と基板搭載型シールドコネクタ１との間の離間距離が大きく、シールドケース３０に切り起こし形成する接地端子３５，３６の延出長が増大する場合でも、プリント回路基板４０への接続時に、接地端子３５，３６に接続の妨げとなる変形が発生し難くなる。従って、プリント回路基板４０のスルーホール４５，４６へ接地端子３５，３６を挿通させる作業も、容易になる。   In the case of the board-mounted shield connector 1 according to the first embodiment described above, the ground terminals 35 and 36 formed on the shield case 30 are formed by ridge lines 351 and 361 extending along the extending direction of the terminals. As a result, the bending rigidity is improved. Therefore, even when the distance between the printed circuit board 40 and the board-mounted shield connector 1 is large and the extension length of the ground terminals 35 and 36 formed by cutting and raising the shield case 30 is increased, the printed circuit board 40 can be extended. At the time of connection, deformation that hinders connection to the ground terminals 35 and 36 is less likely to occur. Accordingly, the operation of inserting the ground terminals 35 and 36 into the through holes 45 and 46 of the printed circuit board 40 is also facilitated.

また、接地端子３５，３６は、稜線部３５１，３６１を形成する折曲加工によって、稜線部３５１，３６１の無い単純な平板構造の場合と比較すると、半田付けの際に半田の乗り（濡れ性）が良くなるため、接地端子３５，３６における半田付け性を向上させることもできる。   In addition, the ground terminals 35 and 36 are subjected to soldering (wetting properties) during soldering compared to the case of a simple flat plate structure without the ridge line portions 351 and 361 by bending processing to form the ridge line portions 351 and 361. Therefore, the solderability of the ground terminals 35 and 36 can be improved.

従って、基板搭載型シールドコネクタ１のプリント回路基板４０への接続作業を容易にすることができる。   Accordingly, the connection work of the board-mounted shield connector 1 to the printed circuit board 40 can be facilitated.

第２実施形態のシールドケース３０Ａでは、プリント回路基板４０に半田付けする接地端子３５，３６の構造を改良している。   In the shield case 30A of the second embodiment, the structure of the ground terminals 35 and 36 soldered to the printed circuit board 40 is improved.

具体的には、第２実施形態における接地端子３５，３６の場合、根本側には、前記稜線部３５１，３６１が形成されず、平板状構造を維持したフラット部３５２，３６２が形成されている。   Specifically, in the case of the ground terminals 35 and 36 in the second embodiment, the ridge line portions 351 and 361 are not formed on the base side, and flat portions 352 and 362 that maintain a flat plate structure are formed. .

端子根本補強部２９は、シールドケース３０Ａを絶縁ハウジング２０Ａ被嵌装着させた際に、接地端子３５，３６のフラット部３５２，３６２に嵌合して、フラット部３５２，３６２を補強するスリーブ構造である。   The terminal base reinforcing portion 29 has a sleeve structure that is fitted into the flat portions 352 and 362 of the ground terminals 35 and 36 to reinforce the flat portions 352 and 362 when the shield case 30A is fitted and attached to the insulating housing 20A. is there.

以上に説明した第２実施形態の基板搭載型シールドコネクタ１Ａの場合、接地端子３５，３６の根本側はフラット部３５２，３６２に形成されて、平板状構造を維持しているため、根本まで稜線部３５１，３６１を形成する場合と比較すると、稜線部３５１，３６１を形成する曲げ加工の施工が容易になる。従って、シールドケース３０Ａの加工性、生産性を向上させることができる。   In the case of the board-mounted shield connector 1A of the second embodiment described above, since the root side of the ground terminals 35 and 36 is formed in the flat portions 352 and 362 and maintains the flat plate structure, the ridge line extends to the root. Compared with the case where the portions 351 and 361 are formed, the bending work for forming the ridge portions 351 and 361 is facilitated. Therefore, the workability and productivity of the shield case 30A can be improved.

また、接地端子３５，３６の平板状の根本側は、絶縁ハウジング２０に装備された端子根本補強部２９によって補強されるため、接地端子３５，３６の根本側を平板状にしていても、接地端子３５，３６には曲げ変形が発生し難く、プリント回路基板４０のスルーホール４５，４６へ接地端子３５，３６を挿通させる作業が容易な長所を残すことができる。   In addition, since the flat base side of the ground terminals 35 and 36 is reinforced by the terminal base reinforcing portion 29 provided in the insulating housing 20, even if the base side of the ground terminals 35 and 36 is flat, The terminals 35 and 36 are not easily deformed by bending, and the advantage that the operation of inserting the ground terminals 35 and 36 through the through holes 45 and 46 of the printed circuit board 40 can be easily left.
