Description

本発明は、基板の一方の面側に配置されたコネクタ本体に基板の他方の面側から相手側コネクタを接続するコネクタに関するものである。   The present invention relates to a connector for connecting a mating connector from the other surface side of a board to a connector body arranged on one side of the board.

従来、この種のコネクタにおいては、基板の一方の面側に固定されるコネクタ本体と、コネクタ本体に保持された複数の端子とを備え、基板に設けられた複数の挿入孔に基板の他方の面側から相手側コネクタの端子を挿入することにより、コネクタ本体の端子に相手側コネクタの端子を接続するようにしたものが知られている（例えば、特許文献１または２参照。）。   Conventionally, in this type of connector, a connector main body fixed to one surface side of the board and a plurality of terminals held by the connector main body are provided, and a plurality of insertion holes provided in the board are inserted into the other insertion hole of the board. It is known that the terminal of the mating connector is connected to the terminal of the connector body by inserting the terminal of the mating connector from the surface side (see, for example, Patent Document 1 or 2).

しかしながら、従来のコネクタでは、基板の挿入孔に相手側コネクタの端子を挿入する際、挿入孔に対して端子を容易に位置決めすることができないため、基板の挿入孔に相手側コネクタの端子を挿入し損なうと、端子の先端が基板の導電パターンに接触し、導電パターンを傷付けるという問題点があった。   However, in the conventional connector, when the terminal of the mating connector is inserted into the insertion hole of the board, the terminal of the mating connector cannot be easily positioned with respect to the insertion hole. If it fails, there is a problem that the tip of the terminal comes into contact with the conductive pattern of the substrate and damages the conductive pattern.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、相手側コネクタをコネクタ本体に接続する際、相手側コネクタの端子の先端で基板の導電パターンを傷付けることのないコネクタを提供することにある。   The present invention has been made in view of the above problems, and its object is to prevent the conductive pattern of the board from being damaged at the tip of the terminal of the mating connector when the mating connector is connected to the connector body. To provide a connector.

本発明は前記目的を達成するために、基板の一方の面側に固定されるコネクタ本体と、コネクタ本体に保持された複数の端子とを備え、基板に設けられた複数の挿入孔に基板の他方の面側から相手側コネクタの端子を挿入することにより、コネクタ本体側の端子に相手側コネクタの端子を接続するようにしたコネクタにおいて、前記基板の他方の面側に配置され、相手側コネクタの各端子を基板の挿入孔に案内する複数のガイド孔を有するガイド部材を備え、ガイド部材には、基板の一部の挿入孔を介してコネクタ本体側に挿入されることによりガイド部材をコネクタ本体に固定する固定部材を設け、固定部材をコネクタ本体の一部の端子に接続することにより、固定部材がコネクタ本体に固定されるように構成している。 In order to achieve the above object, the present invention comprises a connector main body fixed to one surface side of a substrate and a plurality of terminals held by the connector main body, and a plurality of insertion holes provided in the substrate are provided in the plurality of insertion holes. In the connector in which the terminal of the mating connector is connected to the terminal on the connector main body side by inserting the terminal of the mating connector from the other surface side, the mating connector is disposed on the other surface side of the board. A guide member having a plurality of guide holes for guiding each terminal of the board to the insertion hole of the board, and the guide member is inserted into the connector main body side through a part of the insertion holes of the board to connect the guide member to the connector A fixing member for fixing to the main body is provided , and the fixing member is fixed to the connector main body by connecting the fixing member to a part of the terminals of the connector main body .

これにより、相手側コネクタの各端子をガイド部材の各ガイド孔に挿入することにより、相手側コネクタの各端子が基板の挿入孔を介してコネクタ本体側の端子に接続されることから、ガイド部材のガイド孔に相手側コネクタの端子を挿入し損なった場合でも、相手側コネクタの端子の先端が基板に接触することがない。また、ガイド部材の固定部材を基板の一部の挿入孔を介してコネクタ本体側に挿入することにより、ガイド部材がコネクタ本体に固定されることから、ガイド部材を基板に直接固定する必要がなく、固定部材を基板の挿入孔に挿入するだけでガイド部材がコネクタ本体に固定される。また、ガイド部材の固定部材をコネクタ本体の一部の端子に接続することにより、固定部材がコネクタ本体に固定されることから、相手側コネクタの端子が接続される端子と共通部品からなる端子を用いて固定部材を固定することができる。 Thus, by inserting each terminal of the mating connector into each guide hole of the guide member, each terminal of the mating connector is connected to a terminal on the connector body side via the insertion hole of the board. Even if the terminal of the mating connector fails to be inserted into the guide hole, the tip of the terminal of the mating connector does not contact the substrate. In addition, since the guide member is fixed to the connector body by inserting the fixing member of the guide member into the connector body through a part of the insertion hole of the board, there is no need to directly fix the guide member to the board. The guide member is fixed to the connector body simply by inserting the fixing member into the insertion hole of the board. Further, by connecting the fixing member of the guide member to a part of the terminals of the connector body, the fixing member is fixed to the connector body. It can be used to fix the fixing member.

本発明によれば、相手側コネクタをコネクタ本体に接続する際、相手側コネクタの端子の先端が基板に接触することがないので、相手側コネクタの端子の先端で基板の導電パターンを傷付けることがないという利点がある。また、ガイド部材を基板に直接固定する必要がなく、固定部材を基板の挿入孔に挿入するだけでガイド部材をコネクタ本体に固定することができるので、ガイド部材の着脱を極めて容易に行うことができる。また、相手側コネクタの端子が接続される端子と共通部品からなる端子を用いて固定部材を固定することができるので、構造の簡素化を図ることができる。 According to the present invention, when the mating connector is connected to the connector body, the tip of the terminal of the mating connector does not come into contact with the substrate. There is no advantage. In addition, it is not necessary to directly fix the guide member to the board, and the guide member can be fixed to the connector body simply by inserting the fixing member into the insertion hole of the board, so that the guide member can be attached and detached very easily. it can. In addition, since the fixing member can be fixed using a terminal made of a common component with the terminal to which the terminal of the mating connector is connected, the structure can be simplified.

In addition, gripping portions 33 are provided at both ends in the width direction of the guide member 30, and each gripping portion 33 is formed so as to extend outward in the width direction from the upper side surface of the guide member 30.

以上のように構成されたコネクタにおいては、図２１に示すようにコネクタ本体１０を基板１の下面側に配置し、コネクタ本体１０の各突起１２を基板１の各位置決め孔１ｂにそれぞれ係合するとともに、コネクタ本体１０の各固定板１３及び各端子２０の接続部２３を基板１の下面に半田付けすることにより、図１９に示すようにコネクタ本体１０が基板１の下面に固定される。その際、コネクタ本体１０の各端子孔１１は、それぞれ基板１の各挿入孔１ａと位置が一致するように配置される。   In the connector configured as described above, the connector main body 10 is disposed on the lower surface side of the substrate 1 as shown in FIG. 21, and each protrusion 12 of the connector main body 10 is engaged with each positioning hole 1 b of the substrate 1. At the same time, the connector main body 10 is fixed to the lower surface of the substrate 1 as shown in FIG. 19 by soldering the fixing plates 13 of the connector main body 10 and the connecting portions 23 of the terminals 20 to the lower surface of the substrate 1. At that time, each terminal hole 11 of the connector main body 10 is arranged so that the position thereof coincides with each insertion hole 1 a of the substrate 1.

次に、図１９及び図２１に示すようにガイド部材３０を基板１の上面側に配置し、ガイド部材３０の各固定ピン３２を基板１の各挿入孔１ａのうち配列方向両端の挿入孔１ａに挿入するとともに、各端子孔１１のうち配列方向両端の端子孔１１に挿入することにより、各固定ピン３２が配列方向両端の端子２０に接続される。その際、各固定ピン３２は、端子２０の各接触片部２２を端子２０の幅方向外側に向かって弾性変形させながら各接触片部２２間に挿入され、固定ピン３２が各接触片部２２によって挟持されることにより、図２０に示すようにガイド部材３０が基板１の上面に配置された状態でコネクタ本体１０に固定される。また、ガイド部材３０の各ガイド孔３１は、それぞれ基板１の各挿入孔１ａのうち配列方向両端の挿入孔１ａを除く他の挿入孔１ａと位置が一致するように配置される。   Next, as shown in FIGS. 19 and 21, the guide member 30 is disposed on the upper surface side of the substrate 1, and the fixing pins 32 of the guide member 30 are inserted into the insertion holes 1 a at both ends in the arrangement direction among the insertion holes 1 a of the substrate 1. In addition, the fixing pins 32 are connected to the terminals 20 at both ends in the arrangement direction by inserting them into the terminal holes 11 at both ends in the arrangement direction. At this time, each fixing pin 32 is inserted between each contact piece 22 while elastically deforming each contact piece 22 of the terminal 20 toward the outside in the width direction of the terminal 20, and the fixing pin 32 is inserted into each contact piece 22. As shown in FIG. 20, the guide member 30 is fixed to the connector main body 10 in a state where the guide member 30 is disposed on the upper surface of the substrate 1. In addition, each guide hole 31 of the guide member 30 is arranged so that the position of each guide hole 31 coincides with the other insertion holes 1 a except for the insertion holes 1 a at both ends in the arrangement direction of the respective insertion holes 1 a of the substrate 1.

前述のように基板１に取り付けられたコネクタに相手側コネクタ２を接続する場合には、図２２に示すように相手側コネクタ２を基板１の上面側に配置し、相手側コネクタ２の各端子３の下端側をガイド部材３０の各ガイド孔３１に上方から挿入する。これにより、相手側コネクタ２の各端子３がガイド部材３０の各ガイド孔３１によって基板１の挿入孔１ａに案内され、相手側コネクタ２の各端子３が基板１の各挿入孔１ａのうち配列方向両端の挿入孔１ａを除く他の挿入孔１ａを挿通し、コネクタ本体１０側の各端子２０のうち配列方向両端の端子２０を除く他の端子２０に接続される。その際、相手側コネクタ２の各端子３は、コネクタ本体１０側の端子２０の各接触片部２２を端子２０の幅方向外側に向かって弾性変形させながら各接触片部２２間に挿入され、相手側コネクタ２の端子３が各接触片部２２によって挟持されることにより、相手側コネクタ２の端子３がコネクタ本体１０側の端子２０に接続される。   When the mating connector 2 is connected to the connector attached to the board 1 as described above, the mating connector 2 is arranged on the upper surface side of the board 1 as shown in FIG. 3 is inserted into each guide hole 31 of the guide member 30 from above. As a result, the terminals 3 of the mating connector 2 are guided to the insertion holes 1a of the board 1 by the guide holes 31 of the guide member 30, and the terminals 3 of the mating connector 2 are arranged in the insertion holes 1a of the board 1. The other insertion holes 1a excluding the insertion holes 1a at both ends in the direction are inserted and connected to other terminals 20 excluding the terminals 20 at both ends in the arrangement direction among the terminals 20 on the connector body 10 side. At that time, each terminal 3 of the mating connector 2 is inserted between each contact piece 22 while elastically deforming each contact piece 22 of the terminal 20 on the connector body 10 side toward the outside in the width direction of the terminal 20, When the terminal 3 of the mating connector 2 is sandwiched between the contact piece portions 22, the terminal 3 of the mating connector 2 is connected to the terminal 20 on the connector body 10 side.

また、相手側コネクタ２の各端子３をガイド部材３０の各ガイド孔３１に挿入する際、各ガイド孔３１に相手側コネクタ２の各端子３を挿入し損なった場合でも、相手側コネクタ２の各端子３の先端はガイド部材３０の上面に接触し、基板１の上面に接触することがない。   Further, when each terminal 3 of the mating connector 2 is inserted into each guide hole 31 of the guide member 30, even if each terminal 3 of the mating connector 2 fails to be inserted into each guide hole 31, The tip of each terminal 3 contacts the upper surface of the guide member 30 and does not contact the upper surface of the substrate 1.

このように、本実施形態のコネクタによれば、相手側コネクタ２の各端子３を基板１の挿入孔１ａに案内する複数のガイド孔３１を有するガイド部材３０を備え、相手側コネクタ２の各端子３をガイド部材３０の各ガイド孔３１に挿入することにより、相手側コネクタ２の各端子３を基板１の挿入孔１ａを介してコネクタ本体１０側の端子２０に接続するようにしたので、ガイド部材３０のガイド孔３１に相手側コネクタ２の端子３を挿入し損なった場合でも、相手側コネクタ２の端子３の先端が基板１の上面に接触することがなく、基板１の導電パターンを相手側コネクタ２の端子３の先端によって傷付けることがないという利点がある。   Thus, according to the connector of this embodiment, the guide member 30 having the plurality of guide holes 31 for guiding each terminal 3 of the mating connector 2 to the insertion hole 1a of the substrate 1 is provided. Since the terminals 3 are inserted into the guide holes 31 of the guide member 30, the terminals 3 of the mating connector 2 are connected to the terminals 20 on the connector body 10 side via the insertion holes 1a of the board 1. Even if the terminal 3 of the mating connector 2 fails to be inserted into the guide hole 31 of the guide member 30, the tip of the terminal 3 of the mating connector 2 does not contact the upper surface of the substrate 1, and the conductive pattern of the substrate 1 is changed. There is an advantage that the tip of the terminal 3 of the mating connector 2 is not damaged.

また、ガイド部材３０に設けた固定ピン３２を基板１の一部の挿入孔１ａを介してコネクタ本体１０側に挿入することにより、ガイド部材３０をコネクタ本体１０に固定するようにしたので、ガイド部材３０を基板１に直接固定する必要がなく、しかも固定ピン３２を基板１の挿入孔１ａに挿入するだけでガイド部材３０をコネクタ本体１０に固定することができ、ガイド部材３０の着脱を極めて容易に行うことができる。この場合、ガイド部材３０の各把持部３３を把持することにより、ガイド部材３０の着脱時の作業性を向上させることができる。   Further, the guide member 30 is fixed to the connector main body 10 by inserting the fixing pin 32 provided on the guide member 30 into the connector main body 10 through a part of the insertion hole 1a of the substrate 1, so that the guide There is no need to directly fix the member 30 to the substrate 1, and the guide member 30 can be fixed to the connector body 10 simply by inserting the fixing pin 32 into the insertion hole 1 a of the substrate 1. It can be done easily. In this case, by gripping each gripping portion 33 of the guide member 30, workability when the guide member 30 is attached / detached can be improved.

また、ガイド部材３０の固定ピン３２をコネクタ本体１０の一部の端子２０に接続することにより、固定ピン３２をコネクタ本体１０に固定するようにしたので、相手側コネクタ２の端子３が接続される端子２０と共通部品からなる端子２０を用いて固定ピン３２を固定することができ、構造の簡素化を図ることができる。   Further, since the fixing pin 32 of the guide member 30 is connected to a part of the terminals 20 of the connector body 10 so that the fixing pin 32 is fixed to the connector body 10, the terminal 3 of the mating connector 2 is connected. The fixing pin 32 can be fixed using the terminal 20 made of a common part with the terminal 20 to be simplified, and the structure can be simplified.

この場合、ガイド部材３０に設けた一対の固定ピン３２を、基板１に配列された各挿入孔１ａのうち配列方向両端の挿入孔１ａに挿入するようにしたので、相手側コネクタ２の端子３が挿入される挿入孔１ａの両側の挿入孔１ａを固定ピン３２用の挿入孔１ａとして用いることができ、基板１の構造を複雑化させることがないという利点がある。   In this case, since the pair of fixing pins 32 provided on the guide member 30 are inserted into the insertion holes 1a at both ends in the arrangement direction among the insertion holes 1a arranged on the substrate 1, the terminals 3 of the mating connector 2 are used. The insertion holes 1a on both sides of the insertion hole 1a can be used as the insertion holes 1a for the fixing pins 32, and there is an advantage that the structure of the substrate 1 is not complicated.

また、ガイド孔３１の端子挿入側を開口部が広がるようにテーパ状に形成したので、相手側コネクタ２の端子３をガイド孔３１に容易に挿入することができ、相手側コネクタ２の接続作業を速やかに行うことができる。   Further, since the terminal insertion side of the guide hole 31 is tapered so that the opening is widened, the terminal 3 of the mating connector 2 can be easily inserted into the guide hole 31 and the mating connector 2 is connected. Can be performed promptly.

更に、ガイド孔３１の挿入孔１ａ側の開口部を、挿入孔１ａのガイド孔３１側の開口部よりも小さく形成したので、ガイド孔３１を通過した相手側コネクタ２の端子３の先端が挿入孔１ａの縁部に当たることがなく、相手側コネクタ２の端子３をコネクタ本体１０の端子孔１１まで常に円滑に挿入することができる。   Furthermore, since the opening on the insertion hole 1a side of the guide hole 31 is formed smaller than the opening on the guide hole 31 side of the insertion hole 1a, the tip of the terminal 3 of the mating connector 2 that has passed through the guide hole 31 is inserted. The terminal 3 of the mating connector 2 can always be smoothly inserted into the terminal hole 11 of the connector body 10 without hitting the edge of the hole 1a.

尚、前記実施形態では、ガイド部材３０の固定ピン３２をコネクタ本体１０側の端子２０に接続するようにしたものを示したが、端子２０を用いずに、専用の固定用部品やコネクタ本体１０の一部を用いて固定ピン３２をコネクタ本体１０側に固定するようにしてもよい。   In the above embodiment, the fixing pin 32 of the guide member 30 is connected to the terminal 20 on the connector main body 10 side. However, without using the terminal 20, a dedicated fixing component or the connector main body 10 is used. The fixing pin 32 may be fixed to the connector main body 10 side using a part of the part.

また、前記実施形態では、ガイド部材３０の固定ピン３２を各挿入孔１ａのうち配列方向両端の挿入孔１ａに挿入するようにしたものを示したが、固定ピン３２を他の挿入孔１ａに挿入してコネクタ本体１０側に固定するようにしてもよい。   Moreover, in the said embodiment, although what fixed the pin 32 of the guide member 30 to the insertion hole 1a of the arrangement direction both ends was shown among each insertion hole 1a, the fixing pin 32 was set to the other insertion hole 1a. You may make it insert and fix to the connector main body 10 side.

更に、前記実施形態では、図９にコネクタ本体の左側面図を示したが、コネクタ本体の右側面図は左側面図と対称にあらわれるため省略する。また、図１４にガイド部材の正面図を示したが、ガイド部材の背面図は正面図と同一にあらわれるため省略する。更に、図１７にガイド部材の左側面図を示したが、ガイド部材の右側面図は左側面図と同一にあらわれるため省略する。   Furthermore, in the said embodiment, although the left view of the connector main body was shown in FIG. 9, since the right view of a connector main body appears symmetrically with a left view, it abbreviate | omits. FIG. 14 shows a front view of the guide member, but a rear view of the guide member appears the same as the front view, and is omitted. Further, FIG. 17 shows a left side view of the guide member, but the right side view of the guide member appears the same as the left side view, and is omitted.

また、前記実施形態では、ガイド部材３０のガイド孔３１を、基板１の各挿入孔１ａのうち配列方向両端の挿入孔１ａを除く他の全ての挿入孔１ａに対応する数だけ設けたものを示したが、例えば図２３に示すように前記実施形態の相手側コネクタ２よりも端子数が少ない他の種類の相手側コネクタ５を接続する場合、ガイド部材３０には、相手側コネクタ５の端子３の存在しない部分に対応するガイド孔３１を設けないようにすれば、端子数の異なる他の相手側コネクタ（例えば前記実施形態の相手側コネクタ２）の誤接続を防止することができる。   Moreover, in the said embodiment, what provided the guide hole 31 of the guide member 30 by the number corresponding to all the other insertion holes 1a except the insertion holes 1a of the both ends of the arrangement direction among each insertion hole 1a of the board | substrate 1 is provided.
