Description

本発明は、例えば一対のプリント基板同士を接続するために用いられるコネクタに関するものである。   The present invention relates to a connector used for connecting a pair of printed circuit boards, for example.

従来、この種のコネクタとしては、互いに一方の面を対向して配置される一対の基板のうち一方の基板に取り付けられる第１のコネクタと、他方の基板に取り付けられる第２のコネクタとを備え、第１及び第２のコネクタを互いに嵌合することにより各基板同士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１参照）。   Conventionally, this type of connector includes a first connector that is attached to one of a pair of boards that are disposed so that one surface of the connector faces the other, and a second connector that is attached to the other board. In addition, there is known one in which the substrates are connected to each other by fitting the first and second connectors to each other (see, for example, Patent Document 1).

前記第１のコネクタは、一方の基板に固定される固定ハウジングと、固定ハウジングに対して移動自在な可動ハウジングと、固定ハウジング及び可動ハウジングに保持された弾性変形可能な複数の第１の端子とを備え、可動ハウジングは各第１の端子によって固定ハウジングに対して移動自在に支持されている。   The first connector includes a fixed housing fixed to one substrate, a movable housing movable with respect to the fixed housing, and a plurality of elastically deformable first terminals held by the fixed housing and the movable housing. The movable housing is supported by the first terminals so as to be movable with respect to the fixed housing.

また、第２のコネクタは、他方の基板に固定されるハウジングと、ハウジングに保持された複数の第２の端子とを備え、ハウジングは第１のコネクタの可動ハウジングと嵌合するようになっている。   The second connector includes a housing fixed to the other substrate and a plurality of second terminals held by the housing, and the housing is adapted to be fitted to the movable housing of the first connector. Yes.

即ち、前記コネクタでは、第１及び第２のコネクタを互いに嵌合した状態で各基板同士が相対的な位置ずれを生ずると、各第１の端子の弾性変形によって第１のコネクタの可動ハウジングが固定ハウジングに対して移動することにより、各基板同士の位置ずれが吸収されるようになっている。   That is, in the connector, if the relative displacement between the substrates occurs when the first and second connectors are fitted together, the movable housing of the first connector is moved by elastic deformation of the first terminals. By moving relative to the fixed housing, the positional deviation between the substrates is absorbed.

特開２００５−５０６９４号公報Japanese Patent Laying-Open No. 2005-50694

しかしながら、前記コネクタでは、第１及び第２のコネクタを互いに接続する際、第１のコネクタの可動ハウジングに第２のコネクタのハウジングを端子の挿入圧に抗して押し込みながら嵌合しなければならないため、基板との接合部に無用な外力が加わわり、接合部の剥離を生じやすいという問題点があった。また、前記接続の際、端子の挿入圧によって可動ハウジングが固定ハウジング側に移動するため、その分だけ端子の嵌合長が不足し、接続信頼性を低下させるという問題点もあった。更に、接続を解除する際、第１のコネクタの可動ハウジングに対する第２のコネクタのハウジングの引き抜き方向に第１の端子が引張られて変形するため、第１の端子の無用な変形による損傷を生じやすいという問題点もあった。   However, in the connector, when the first and second connectors are connected to each other, the housing of the second connector must be fitted into the movable housing of the first connector while being pushed against the insertion pressure of the terminal. Therefore, there is a problem that unnecessary external force is applied to the joint portion with the substrate, and the joint portion is liable to be peeled off. Further, at the time of the connection, the movable housing moves to the fixed housing side due to the insertion pressure of the terminal, so that there is a problem that the fitting length of the terminal is insufficient and the connection reliability is lowered. Further, when the connection is released, the first terminal is pulled and deformed in the pulling direction of the housing of the second connector with respect to the movable housing of the first connector, so that the first terminal is damaged due to unnecessary deformation. There was also a problem that it was easy.

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、第１及び第２のコネクタを互いに接続する際、端子の挿入圧を受けることなく嵌合することができるとともに、第１の端子を変形させることなく第１及び第２のコネクタの接続及び接続解除を行うことのできる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 that when the first and second connectors are connected to each other, they can be fitted without receiving terminal insertion pressure. An object of the present invention is to provide a connector capable of connecting and disconnecting the first and second connectors without deforming the first terminal.

本発明は前記目的を達成するために、互いに一方の面を対向して配置される一対の基板のうち一方の基板に取り付けられる第１のコネクタと、他方の基板に取り付けられる第２のコネクタとを備え、第１のコネクタは、一方の基板に固定される固定ハウジングと、固定ハウジングに対して移動自在な可動ハウジングと、固定ハウジング及び可動ハウジングに保持され、可動ハウジングを移動自在に支持する弾性変形可能な第１の端子とを有し、第２のコネクタは、他方の基板に固定されるハウジングと、ハウジングに保持された第２の端子とを有し、第１及び第２のコネクタを互いに接続することにより各基板同士を接続するようにしたコネクタにおいて、前記第２のコネクタのハウジングに回動自在なレバーを設け、レバーを第１のコネクタの可動ハウジングに係合して所定方向に回動すると、第１及び第２の各コネクタが互いに引き寄せられて第１の端子と第２の端子とが互いに接続されるように構成している。   In order to achieve the above object, the present invention provides a first connector that is attached to one of a pair of substrates that are arranged to face each other, and a second connector that is attached to the other substrate. The first connector includes a fixed housing fixed to one of the substrates, a movable housing movable with respect to the fixed housing, and an elastic that is held by the fixed housing and the movable housing and movably supports the movable housing. The second connector has a housing fixed to the other substrate, a second terminal held by the housing, and the first and second connectors are connected to each other. In the connector in which the boards are connected to each other by being connected to each other, a rotatable lever is provided on the housing of the second connector, and the lever is connected to the first connector. When rotated in a predetermined direction engages the movable housing, it is configured such that the first terminal the first and second of each connector are drawn together and the second terminals are connected to each other.

これにより、レバーを第１のコネクタの可動ハウジングに係合して所定方向に回動すると、第１及び第２のコネクタが互いに引き寄せられて第１の端子と第２の端子とが互いに接続されることから、第２のコネクタのハウジングを第１のコネクタの可動ハウジングに端子の挿入圧に抗して押し込みながら嵌合する必要がなく、接続時に第１の端子の可動部が変形することもない。   Thus, when the lever is engaged with the movable housing of the first connector and rotated in a predetermined direction, the first and second connectors are pulled toward each other and the first terminal and the second terminal are connected to each other. Therefore, it is not necessary to fit the housing of the second connector into the movable housing of the first connector while pushing it against the insertion pressure of the terminal, and the movable portion of the first terminal may be deformed at the time of connection. Absent.

本発明によれば、第２のコネクタのハウジングを第１のコネクタの可動ハウジングに端子の挿入圧に抗して押し込みながら嵌合する必要がないので、レバーの操作によって第１及び第２のコネクタを容易に接続することができる。これにより、基板との接合部に接続時の無用な外力が加わることがなく、接合部の剥離を効果的に防止することができる。この場合、第１の端子を変形させることなく接続することができるので、接続時の第１の端子の変形によって端子の嵌合長が不足することがなく、接続信頼性の向上を図ることができる。更に、接続を解除する際にも第１の端子を変形させることがないので、第１の端子の無用な変形による損傷を防止することもできる。   According to the present invention, since it is not necessary to fit the housing of the second connector into the movable housing of the first connector while pushing against the insertion pressure of the terminal, the first and second connectors are operated by operating the lever. Can be easily connected. Thereby, useless external force at the time of a connection is not added to the junction part with a board | substrate, and peeling of a junction part can be prevented effectively. In this case, since the first terminal can be connected without being deformed, the fitting length of the terminal is not short due to the deformation of the first terminal at the time of connection, and the connection reliability can be improved. it can. Furthermore, since the first terminal is not deformed even when the connection is released, damage due to unnecessary deformation of the first terminal can be prevented.

A mating arcuate engagement hole 22e is provided, and the lever 22 rotates about the rotation fulcrum 21e. The engagement hole 22e is formed such that the distance from the other end side to the rotation fulcrum portion 21e is shorter than the distance from one end side to the rotation fulcrum portion 21e, and the protrusion 12b is provided at one end of the engagement hole 22e. A notch 22f that can be inserted into and out of 22e is provided. In this case, the outer inner peripheral surface of the engagement hole 22e is formed in a curved shape, and the inner inner peripheral surface of the engagement hole 22e is formed in a linear shape. That is, as shown in FIG. 9, when the lever 22 is in the open position (clockwise rotation stop position in the figure), one end (notch 22f) of the engagement hole 22e is positioned at the lower end of the rotation portion 22a. The other end of the engagement hole 22e is positioned on the protrusion 21f of the housing 21. Further, as shown in FIG. 10, when the lever 22 is in the closed position (counterclockwise rotation stop position in the figure), the other end of the engagement hole 22e is positioned at the lower end of the rotation portion 22a, and the lock hole 22 d engages with the protrusion 21 f of the housing 21.

各第２の端子２３は、導電性の金属によって板状に形成され、ハウジング２１の各端子孔２１ａにそれぞれ保持されている。第２の端子２３は、第１のコネクタ１０の第１の端子１３と接触する接触部２３ａと、基板２に接続される接続部２３ｂとからなる。接触部２３ａは上下方向に板状に延びるように形成され、その下端側はハウジング２１の下面から下方に向かって突出している。接続部２３ｂは接触部２３ａの上端から幅方向一方に向かって延びるように形成され、その先端側はハウジング２１の側面から側方に向かって突出している。また、接続部２３ｂの先端側は下方に突出した部分を有し、この部分が基板２に接続されるようになっている。   Each second terminal 23 is formed in a plate shape from a conductive metal and is held in each terminal hole 21 a of the housing 21. The second terminal 23 includes a contact portion 23 a that contacts the first terminal 13 of the first connector 10 and a connection portion 23 b that is connected to the substrate 2. The contact portion 23 a is formed so as to extend in a plate shape in the vertical direction, and the lower end side thereof protrudes downward from the lower surface of the housing 21. The connection portion 23b is formed so as to extend from the upper end of the contact portion 23a toward one side in the width direction, and the tip end side thereof protrudes from the side surface of the housing 21 toward the side. Further, the distal end side of the connecting portion 23 b has a portion protruding downward, and this portion is connected to the substrate 2.

以上のように構成されたコネクタにおいては、第１のコネクタ１０の固定ハウジング１１の各固定部材１１ｂと各第１の端子１３の接続部１３ｃを基板１に半田付けすることにより、第１のコネクタ１０が基板１に取り付けられる。また、第２のコネクタ２０を基板２の取付孔２ａ内に配置するとともに、ハウジング２１の各固定部材２１ｃと各第２の端子２３の接続部２３ｂを基板２に半田付けすることにより、第２のコネクタ２０が基板２に取り付けられる。その際、第２のコネクタ２０の各固定部２１ｂが基板２の上面に載置され、第２のコネクタ２０の上端側が基板２の上面側に配置される。   In the connector configured as described above, the first connector 10 is soldered to the substrate 1 by soldering the fixing members 11b of the fixing housing 11 of the first connector 10 and the connection portions 13c of the first terminals 13 to each other. 10 is attached to the substrate 1. In addition, the second connector 20 is disposed in the mounting hole 2a of the substrate 2, and the fixing members 21c of the housing 21 and the connection portions 23b of the second terminals 23 are soldered to the substrate 2, thereby The connector 20 is attached to the substrate 2. At this time, each fixing portion 21 b of the second connector 20 is placed on the upper surface of the substrate 2, and the upper end side of the second connector 20 is disposed on the upper surface side of the substrate 2.

第１のコネクタ１０と第２のコネクタ２０とを接続する場合は、図９、図１２及び図１５に示すように、レバー２２を前記開放位置に回動した状態で、第１のコネクタ１０の可動ハウジング１２と第２のコネクタ２０のハウジング２１とを嵌合する。その際、各コネクタ１０，２０は、図１０及び図１３に示すように、第２のコネクタ２０の第２の端子２３の接触部２３ａが可動ハウジング１２の挿入孔１２ａに挿入されるとともに、第２の端子２３の接触部２３ａの先端が第１の端子１３の各接触部１３ａの先端に当接する。また、各コネクタ１０，２０を嵌合すると、可動ハウジング１２の各突部１２ｂがレバー２２の切り欠き２２ｆを介して係合孔２２ｅの一端側に入り込む。この状態は、第１のコネクタ１０の可動ハウジング１２と第２のコネクタ２０のハウジング２１とが完全には嵌合していない半嵌合状態であるが、可動ハウジング１２は第２のコネクタ２０の各延出部２１ｄとレバー２２の各回動部２２ａによって前後方向及び幅方向の移動を規制される。次に、図１１、図１４及び図１６に示すように、レバー２２を閉鎖位置に向かって図中反時計回りに回動すると、係合孔２２ｅは一端側から回動支点部２１ｅまでの距離よりも他端側から回動支点部２１ｅまでの距離が短くなるように形成されているため、係合孔２２ｅの回動に伴って可動ハウジング１２の突部１２ｂが回動支点部２１ｅに近づくように上下方向に引き寄せられ、第２の端子２３の接触部２３ａが第１の端子１３の各接触部１３ａ間に圧入される。これにより、第１の端子１３と第２の端子２３が互いに接続される。また、レバー２２の回動により係合孔２２ｅの他端が可動ハウジング１２の各突部１２ｂまで達すると、完全な嵌合状態となり、第１のコネクタ１０と第２のコネクタ２０との接続が完了する。その際、レバー２２のロック孔２２ｄがハウジング２１の突起２１ｆに係合し、レバー２２がロックされる。   When connecting the first connector 10 and the second connector 20, as shown in FIGS. 9, 12, and 15, the lever 22 is rotated to the open position and the first connector 10 is connected. The movable housing 12 and the housing 21 of the second connector 20 are fitted. At that time, as shown in FIGS. 10 and 13, each connector 10, 20 has a contact portion 23 a of the second terminal 23 of the second connector 20 inserted into the insertion hole 12 a of the movable housing 12, and The tip of the contact portion 23 a of the second terminal 23 comes into contact with the tip of each contact portion 13 a of the first terminal 13. Further, when the connectors 10 and 20 are fitted, the protrusions 12b of the movable housing 12 enter one end side of the engagement hole 22e through the notches 22f of the lever 22. This state is a semi-fitted state where the movable housing 12 of the first connector 10 and the housing 21 of the second connector 20 are not completely fitted, but the movable housing 12 is not attached to the second connector 20. The movement in the front-rear direction and the width direction is regulated by each extending portion 21 d and each rotating portion 22 a of the lever 22. Next, as shown in FIGS. 11, 14, and 16, when the lever 22 is rotated counterclockwise in the drawing toward the closed position, the engagement hole 22e is a distance from one end side to the rotation fulcrum portion 21e. Since the distance from the other end side to the rotation fulcrum portion 21e is shorter, the protrusion 12b of the movable housing 12 approaches the rotation fulcrum portion 21e as the engagement hole 22e rotates. Thus, the contact portion 23 a of the second terminal 23 is press-fitted between the contact portions 13 a of the first terminal 13. Thereby, the first terminal 13 and the second terminal 23 are connected to each other. Further, when the other end of the engagement hole 22e reaches each projection 12b of the movable housing 12 by the rotation of the lever 22, a complete fitting state is established, and the connection between the first connector 10 and the second connector 20 is established. Complete. At that time, the lock hole 22d of the lever 22 engages with the protrusion 21f of the housing 21, and the lever 22 is locked.

前記接続状態において、各基板１，２同士が前後方向（図中Ｘ方向）、幅方向（図中Ｙ方向）または上下方向（図中Ｚ方向）に相対的な位置ずれを生ずると、第１のコネクタ１０の可動ハウジング１２が固定ハウジング１１に対して移動することにより、各基板１，２同士の位置ずれが吸収される。   In the connected state, when the substrates 1 and 2 are displaced relative to each other in the front-rear direction (X direction in the figure), the width direction (Y direction in the figure), or the vertical direction (Z direction in the figure), the first When the movable housing 12 of the connector 10 moves relative to the fixed housing 11, the positional deviation between the substrates 1 and 2 is absorbed.

また、第１のコネクタ１０と第２のコネクタ２０との接続を解除する場合は、レバー２２を前記閉鎖位置から図中時計回りに回動すると、前記接続時とは反対方向への係合孔２２ｅの回動に伴って可動ハウジング１２の突部１２ｂが回動支点部２１ｅから引き離され、第２の端子２３の接触部２３ａが第１の端子１３の各接触部１３ａ間から引き抜かれる。これにより、第１のコネクタ１０の可動ハウジング１２と第２のコネクタ２０のハウジング２１とが前記半嵌合状態となり、第１のコネクタ１０と第２のコネクタ２０とが分離可能となる。   Further, when the connection between the first connector 10 and the second connector 20 is released, when the lever 22 is rotated clockwise from the closed position in the drawing, the engagement hole is formed in the opposite direction to that at the time of the connection. With the rotation of 22e, the protrusion 12b of the movable housing 12 is pulled away from the rotation fulcrum portion 21e, and the contact portion 23a of the second terminal 23 is pulled out from between the contact portions 13a of the first terminal 13. As a result, the movable housing 12 of the first connector 10 and the housing 21 of the second connector 20 are in the half-fitted state, and the first connector 10 and the second connector 20 can be separated.

このように、本実施形態のコネクタによれば、第２のコネクタ２０のハウジング２１に回動自在なレバー２２を設け、レバー２２を第１のコネクタ１０の可動ハウジング１２の突部１２ｂに係合して所定方向に回動すると、第１及び第２のコネクタ１０，２０が互いに引き寄せられて第１のコネクタ１０の第１の端子１３と第２のコネクタ２０の第２の端子２３とが互いに接続されるようにしたので、第２のコネクタ２０のハウジング２１を第１のコネクタ１０の可動ハウジング１２に各端子１３，２３の挿入圧に抗して押し込みながら嵌合する必要がなく、レバー２２の操作によって第１及び第２のコネクタ１０，２０を容易に接続することができる。これにより、各基板１，２との接合部に接続時の無用な外力が加わることがなく、接合部の剥離を効果的に防止することができる。この場合、第１の端子１３の可動部１３ｂを変形させることなく接続することができるので、接続時の第１の端子１３の変形によって各端子２３，２３の嵌合長が不足することがなく、接続信頼性の向上を図ることができる。更に、接続を解除する際にも第１の端子１３の可動部１３ｂを変形させることがないので、第１の端子１３の無用な変形による損傷を防止することもできる。   As described above, according to the connector of the present embodiment, the rotatable lever 22 is provided in the housing 21 of the second connector 20, and the lever 22 is engaged with the protrusion 12 b of the movable housing 12 of the first connector 10. Then, when the first connector 10 and the second connector 20 are rotated in a predetermined direction, the first and second connectors 10 and 20 are attracted to each other, and the first terminal 13 of the first connector 10 and the second terminal 23 of the second connector 20 are mutually connected. Since the connection is made, it is not necessary to fit the housing 21 of the second connector 20 into the movable housing 12 of the first connector 10 while pushing against the insertion pressure of the terminals 13 and 23, and the lever 22 Thus, the first and second connectors 10 and 20 can be easily connected. Thereby, useless external force at the time of connection is not added to the junction part with each board | substrate 1 and 2, and peeling of a junction part can be prevented effectively. In this case, since the movable portion 13b of the first terminal 13 can be connected without being deformed, the fitting length of the terminals 23 and 23 is not insufficient due to the deformation of the first terminal 13 at the time of connection. The connection reliability can be improved. Furthermore, since the movable portion 13b of the first terminal 13 is not deformed even when the connection is released, damage due to unnecessary deformation of the first terminal 13 can be prevented.

また、レバー２２が前記所定方向に回動する前の状態で、第１のコネクタ１０の可動ハウジング１２と第２のコネクタ２０のハウジング２１とを互いに前後方向及び幅方向の移動を規制可能に嵌合するようにしたので、レバー２２を操作する前に第１及び第２のコネクタ１０，２０を半嵌合状態に保持することができ、接続作業を極めて容易に行うことができる。   Further, before the lever 22 is rotated in the predetermined direction, the movable housing 12 of the first connector 10 and the housing 21 of the second connector 20 are fitted so as to be able to restrict movement in the front-rear direction and the width direction. Since they are combined, the first and second connectors 10 and 20 can be held in the half-fitted state before the lever 22 is operated, and the connection work can be performed very easily.

更に、第２のコネクタ２０のハウジング２１を基板２の取付孔２ａ内に位置するように取り付けるとともに、第２のコネクタ２０のレバー２２を基板２の他方の面側から回動操作するようにしたので、各基板１，２を互いに一方の面側から対向させた状態でも、他方の基板２の他方の面側からレバー２２を操作することができ、レバー２２の操作を極めて容易に行うことができる。   Further, the housing 21 of the second connector 20 is mounted so as to be positioned in the mounting hole 2a of the board 2, and the lever 22 of the second connector 20 is rotated from the other surface side of the board 2. Therefore, even when the substrates 1 and 2 are opposed to each other from one surface side, the lever 22 can be operated from the other surface side of the other substrate 2, and the lever 22 can be operated very easily. it can.
