  In the case of the conventional connector, the lever is deformed along the thickness direction of the first housing. Further, the pressing protrusion protrudes in the thickness direction on the inner surface of the lever. Further, the elastic tongue of the first contact for the detection circuit is deformed in the thickness direction. Therefore, since the space for displacing the lever, the pressing protrusion, and the elastic tongue piece must be secured in the thickness direction, both connectors are bulky in the thickness direction.

  Further, since the elastic tongue of the first contact for the detection circuit is pressed by the pressing protrusion of the lever, the first contact for the detection circuit is the above-mentioned of the lever. Only one can be provided on one side in the thickness direction, and the number and position of the first contacts for the detection circuit are limited.

  The present invention has been made paying attention to such points, and the object of the present invention is to provide the second contact when one of the first connector and the second connector is inserted into the other connector. If the contact portion is not completely inserted into the first contact, the contact piece of the first contact is pushed outward in the width direction perpendicular to the thickness direction in the receiving space, and the contact portion and the contact piece are When the contact is prevented and the contact piece tries to return to the original position when the insertion is complete, the contact portion and the contact piece come into contact with each other, so that the connectors are completely fitted. In addition, it is possible to reduce the number of connectors in the thickness direction, and to increase the number of contacts to be detected and the degree of freedom of installation positions. It is to provide a connector having.

In order to achieve the above object, a connector having the first coupling detection means of the present invention comprises:
The direction toward the mating connector when the mating sides face each other is the mating direction, the direction away from the mating connector is the anti-mating direction, the direction orthogonal to the mating direction is the width direction, and the fitting When the thickness direction is the direction perpendicular to both the combined direction and the width direction,
A contact piece provided so as to have a contact located in the receiving space and to be elastically deformed in the width direction so that the contact is displaced to the side away from the center of the receiving space in the width direction and exits from the receiving space. A first housing having a first contact having an opening that opens to the fitting side and accommodates the first contact, and an opening that opens the accommodation chamber to one side in the thickness direction. When the guide piece is displaced to the side away from the center of the receiving space in the width direction on one side of the contact piece in the thickness direction, the contact piece is interlocked to move the contact to the receiving space. A first connector provided to exit from
A second contact having a contact portion formed in a shape corresponding to the receiving space and extending in the fitting direction, and a portion where the second contact is provided and shifted to one side in the thickness direction from the contact portion And a second connector having a second housing provided with an operating piece protruding to the other side in the thickness direction,
When one of the connectors is inserted into the other connector, if the contact portion is not completely accommodated in the receiving space, the operating piece passes the guide piece through the guide piece and the receiving space in the width direction. When the contact portion is completely accommodated in the receiving space, the operating piece is more than the guide piece above the first connector. The contact portion and the contact point are in contact with each other so that the contact piece is returned to the original position by coming off in the anti-fitting direction.

  When one of the connectors is inserted into the other connector, if the contact portion is not completely accommodated in the receiving space, the operating piece passes the guide piece through the guide piece and the receiving space in the width direction. Is pushed away from the center to prevent contact between the contact portion and the contact point, so that if the contact portion and the first contact are detected not to conduct, the first connector and the second connector are It is detected that the fitting is not complete. On the other hand, when the contact portion is completely accommodated in the receiving space, the contact piece tends to return to the original position as the operating piece comes out in the anti-fitting direction of the first connector rather than the guide piece. Since the contact portion and the contact point are in contact with each other, if it is detected that the contact portion and the first contact are conductive, the first connector and the second connector are completely fitted. Is detected.

  In this case, since the contact piece and the guide piece are only elastically deformed in the width direction, it is not necessary to secure a space for the contact piece and the guide piece to be displaced in the thickness direction. It is possible to make the dimension in the thickness direction of both the connectors smaller, that is, thinner than that of the connector. Further, the contact piece and the guide piece operate independently of the conventional lever. Therefore, even when the conventional lever is not provided in the first connector, the first contact to be detected can be provided, and even when the conventional lever is provided, the detection is performed without relation to the lever. The 1st contact used as the object of can be provided. Therefore, regardless of whether or not the conventional lever is provided in the first connector, the number of contacts to be detected and the degree of freedom of the installation position are high. Further, when the contact portion completely accommodated in the receiving space is removed from the receiving space, the operating piece passes through the side farther from the center of the receiving space in the width direction than the guide piece. In this configuration, the guide piece is relatively pushed toward the side closer to the center of the receiving space in the width direction, but the guide piece is displaced toward the side closer to the center of the receiving space in the width direction. Even so, when the contact pieces are not interlocked, the contact pieces are not deformed, so that the pulling force is prevented from increasing due to the elastic force of the contact pieces.

The connector having the second coupling detection means of the present invention is the connector having the first coupling detection means,
The two contact pieces are provided so that the two contact points are located on both sides of the center of the receiving space in the width direction.

The guide arm or the guide piece is provided on the contact piece so as to hang from the side near the center of the receiving space in the width direction of the contact piece.

  According to this configuration, when the guide piece is displaced to the side away from the center of the receiving space in the width direction, the guide arm moves its free end away from the center of the receiving space in the width direction. The guide arm or the guide piece pushes the contact piece to the side away from the center of the receiving space in the width direction to bring the contact out of the receiving space and the contact portion. Block contact with the contacts. On the other hand, when the operating piece comes out in the anti-fitting direction of the first connector rather than the guide piece, the guide piece approaches the center of the receiving space in the width direction by the restoring force of the guide arm. The contact part is returned to the original position, and the contact piece comes into contact with the contact point in an attempt to return the contact piece to the original position.

The connector having the fourth coupling detection means of the present invention is the connector having any one of the first to third coupling detection means,
When one connector is inserted into the other connector, the end on the fitting side of the first connector in the guide piece is more than the end on the fitting side of the second connector in the operating piece. It is located on the far side from the center of the receiving space in the width direction.

  In this case, when the contact portion of the second contact is inserted into the receiving space of the first contact, the operating piece is closer to the center of the receiving space in the width direction than the guide piece. The guide piece is relatively pushed to the side away from the center of the receiving space in the width direction, so that the contact piece is away from the center of the receiving space in the width direction. To prevent contact between the contact portion and the contact point. Then, the contact piece comes into contact with the contact point as the contact piece tries to return to the original position when the operating piece is removed in the anti-fitting direction of the first connector from the guide piece.

The connector having the fifth coupling detection means of the present invention is the connector having any one of the first to fourth coupling detection means,
When the contact portion is accommodated in the receiving space, an end of the guide connector on the side opposite to the mating side of the first connector is an end of the operating piece on the side opposite to the mating side of the second connector. It is located closer to the center of the receiving space than the portion in the width direction.

  According to this configuration, when the contact portion that is completely accommodated in the receiving space is removed from the receiving space, the working piece is located on the side farther from the center of the receiving space in the width direction than the guide piece. Therefore, the guide piece is relatively pushed toward the side closer to the center of the receiving space in the width direction.

The connector having the sixth coupling detection means of the present invention is the connector having any one of the first to fifth coupling detection means,
A lever having a first locking portion that can be elastically deformed and a second locking portion that engages with the first locking portion of the lever when one connector is inserted into the other connector. It is allocated to both the above connectors,

Attempts to contact the contact part and the contact point are performed simultaneously.

  In this way, when the first connector and the second connector are completely fitted, the operation piece is detached from the guide piece, and the contact piece tries to return to the original position. In addition, since the response by the engagement between the first locking portion and the second locking portion is obtained, it is detected that the first connector and the second connector are completely fitted. Is done.

  In the connector having the first coupling detecting means of the present invention, when one connector is inserted into the other connector, the contact portion of the second contact is not completely inserted into the first contact. The contact piece is pushed outward in the width direction perpendicular to the thickness direction in the receiving space to prevent contact between the contact portion and the contact piece, and when the insertion is complete, the contact piece is returned to its original position. Since the contact portion and the contact piece come into contact with each other in an attempt to return, the connector has a function of detecting whether or not the connectors are completely fitted, and the connectors can be made thinner in the thickness direction. In addition, the number of contacts to be detected and the degree of freedom of the installation position can be increased. In addition, when the contact piece is configured to pass through the side far from the center of the receiving space in the width direction with respect to the guide piece when the contact portion is removed from the receiving space, the guide piece is If the contact pieces are not interlocked even if they are displaced toward the side closer to the center of the receiving space in the width direction, an increase in the pulling force can be prevented.

Sometimes, the first locking portion of the lever may be provided so as to be distributed to the two connectors, and the second locking portion to be engaged.

  The contacts 110 other than the first contact 110 in the first connector 100 have the same structure as the first contact 110, but the protrusions 113b may not be provided on these contacts 110, Other structures may be used. The first housing 120 is provided with a storage chamber 123 that opens to the fitting side and stores the other contacts 110. The first housing 120 is not provided with the opening, the guide arm, the guide piece, or the like corresponding to the storage chamber 123, but any of these may be provided. The contacts 210 other than the second contact 210 in the second connector 200 have the same structure as the second contact 210, but may have other structures. The second housing 220 is provided with the other contact 210 with the same fixing structure as the second contact 210. There is no working piece or the like corresponding to these contacts 210, but the working piece or the like may be provided there.

  When the guide piece 126 is displaced in the width direction to the side away from the center 112a of the receiving space 112, the guide piece 126 is configured to interlock the contact piece 113 so as to take out the contact 113a from the receiving space 112. When the guide piece 126 is displaced toward the side closer to the center 112a of the receiving space 112 in the width direction, the contact piece 113 is not interlocked. However, even when the guide piece is displaced toward the side closer to the center of the receiving space in the width direction, the contact piece is interlocked to be displaced toward the side closer to the center of the receiving space in the width direction. You may comprise as follows. In such a case, when the contact portion is accommodated in the receiving space, an end of the guide connector on the side opposite to the first connector of the first connector is connected to the counter connector of the second connector on the operating piece. It is preferable to be configured to be located on the side farther from the center of the receiving space in the width direction than the end on the side. When configured in this way, for example, the guide piece may be connected to the contact piece without providing the guide arm.

  Therefore, in the case of the connector having the coupling detection means of the first embodiment, when the first connector 100 is inserted into the second connector 200, as shown in FIG. 13, FIG. 14, and FIG. As shown in order in FIGS. 17, 18, and 19, the first connector 100 is fitted into the second connector 200 so that the first contact 110 and the second contact 210 come into contact with each other. When the first connector 100 is removed from the second connector 200, the first connector 100 is sequentially shown in FIGS. 15, 16, and 13, and is sequentially shown in FIGS. The fitting of the one connector 100 with the second connector 200 is released, the first contact 110 and the second contact 210 are separated, and the contact is released.

  In the course of inserting the first connector 100 into the second connector 200, as shown in FIGS. 14 and 18, if the contact portion 212 is not completely accommodated in the receiving space 112, the operating piece 223 is used. Pushes the contact piece 113 through the guide piece 126 to the side away from the center 112a of the receiving space 112 in the width direction to prevent the contact portion 212 and the contact 113a from contacting each other. If it is detected that 212 and the first contact 110 are not conductive, it is detected that the first connector 100 and the second connector 200 are not completely fitted. Meanwhile, when the process of inserting the first connector 100 into the second connector 200 is completed and the contact portion 212 is completely accommodated in the receiving space 112 as shown in FIGS. Since the contact piece 113 tries to return to the original position when the piece 223 is pulled out from the guide piece 126 in the anti-fitting direction of the first connector 100, the contact portion 212 and the contact 113a come into contact with each other. If it is detected that the contact portion 212 and the first contact 110 are electrically connected, it is detected that the first connector 100 and the second connector 200 are completely fitted.

  In that case, since the contact piece 113 and the guide piece 126 are only elastically deformed in the width direction, it is not necessary to secure a space for the displacement of the contact piece 113 and the guide piece 126 in the thickness direction. Thus, the thickness direction dimension of the first connector 100 and the second connector 200 can be made smaller, that is, thinner than the conventional connector. Further, the contact piece 113 and the guide piece 126 operate independently of the lever 127. Therefore, even when the first connector 100 is not provided with the lever 127, the first contact 110 to be detected can be provided, and even when the lever 127 is provided, it is not related to the lever 127. A first contact 110 to be detected can be provided. Therefore, regardless of whether or not the first connector 100 is provided with the lever, the number of contacts to be detected and the degree of freedom of the installation position are high. Therefore, the connector having the coupling detection means of the first embodiment has a function of detecting whether or not the fitting of the first connector 100 and the second connector 200 is complete, and the first connector. 100 and the second connector 200 can be thinned in the thickness direction, and the number of contacts to be detected and the degree of freedom of the installation position can be increased. Further, as shown in FIGS. 16 and 20, when the contact portion 212 completely accommodated in the receiving space 112 is pulled out from the receiving space 112, the operating piece 223 has a width relative to the guide piece 126. The guide piece 126 is relatively pushed toward the side closer to the center 112a of the receiving space 112 in the width direction because it is configured to pass the side far from the center 112a of the receiving space 112 in the direction. However, even if the guide piece 126 is displaced toward the side closer to the center 112a of the receiving space 112 in the width direction, the contact piece 113 is not interlocked. Therefore, the contact piece 113 is not deformed. It is possible to prevent the pulling force from increasing due to the elastic force.

  The connector having the coupling detection means of the present invention includes an embodiment in which the number of at least one member among the contact piece, the guide piece, and the operating piece is one. Among such various embodiments, the connector having the coupling detection means of the first embodiment has two contact pieces 113 and two contact points 113a in the width direction in the receiving space. 112 is provided on both sides of the center 112a, two guide pieces 126 are provided corresponding to the two contact pieces 113, and two operating pieces 223 are provided. , Provided corresponding to the two guide pieces 126, respectively. In this way, the action exerted by the operating piece 223, the guide piece 126, the contact piece 113, etc. is exhibited on both sides of the center 112a of the receiving space 112 in the width direction. Therefore, the present invention is specifically applied to a pair of connectors in which the contact piece 113 includes the first connectors 100 provided on both sides with respect to the center 112a of the receiving space 112 in the width direction. Can do.

  The connector having the coupling detection means of the present invention does not limit the structure for the guide piece to interlock the contact piece. The connector having the coupling detection means of the present invention includes, for example, an embodiment in which the guide piece is connected to the contact piece without providing the guide arm. Among such various embodiments, the connector having the coupling detection means of the first embodiment is fitted into the first housing 120 so that it can be elastically deformed in the width direction at the opening 124. The guide arm 125 extending in the direction is provided, the guide piece 126 is provided at the free end of the guide arm 125, the guide arm 125 or the guide piece 126 is provided on the contact piece 113, and the width direction of the contact piece 113 is provided. The receiving space 112 is provided so as to hang from the side closer to the center 112a. In this way, when the guide piece 126 is displaced to the side away from the center 112a of the receiving space 112 in the width direction, the guide arm 125 moves its free end in the width direction of the receiving space 112. The contact arm 113 or the guide piece 126 is elastically deformed so as to be displaced away from the center 112a, and the contact piece 113 is pushed toward the side away from the center 112a of the receiving space 112 in the width direction. 113a is taken out of the receiving space 112 and the contact between the contact portion 212 and the contact 113a is blocked. On the other hand, when the operating piece 223 is disengaged from the guide piece 126 in the anti-fitting direction of the first connector 100, the receiving piece 112 is moved in the width direction by the restoring force of the guide arm 125. The contact portion 113 and the contact point 113a come into contact with each other as the contact piece 113 returns to the original position by moving toward the side approaching the center 112a. Thus, one structure for the guide piece 126 to interlock the contact piece 113 could be exemplified.

  The connector having the coupling detection means of the present invention does not limit the structure for the operating piece to move the guide piece, and does not limit the shapes of the guide piece and the operating piece. Among such various embodiments, the connector having the coupling detection means of the first embodiment is the first connector 100 in the guide piece 126 when the first connector 100 is inserted into the second connector 200. The fitting-side end 126a of one connector 100 is farther from the center 112a of the receiving space 112 in the width direction than the fitting-side end 223a of the second connector 200 in the operating piece 223. Located on the side. In this way, as shown in FIGS. 13 to 14, when the contact portion 212 of the second contact 210 is inserted into the receiving space 112 of the first contact 110, the operating piece 223 is moved to the guide piece. 126 passes through the side closer to the center 112a of the receiving space 112 in the width direction, so that the guide piece 126 is pushed toward the side away from the center 112a of the receiving space 112 in the width direction. As a result, the contact piece 113 is pushed away from the center 112a of the receiving space 112 in the width direction, and contact between the contact portion 212 and the contact 113a is prevented. Then, as shown in FIG. 15, the contact piece 113 tries to return to the original position when the operating piece 223 is removed from the guide piece 126 in the anti-fitting direction of the first connector 100. 212 contacts the contact 113a. Thereby, the configuration for passing the operating piece 223 through the side close to the center 112a of the receiving space 112 in the width direction with respect to the guide piece 126 could be exemplified.

  Further, the connector having the coupling detecting means of the first embodiment is configured such that the anti-fitting side of the first connector 100 in the guide piece 126 when the contact portion 212 is accommodated in the receiving space 112. The end 126b of the operating piece 223 is positioned closer to the center 112a of the receiving space 112 in the width direction than the end 223b of the second connector 200 on the side opposite to the mating side. In this way, as shown in FIGS. 15 to 16, when the contact portion 212 completely accommodated in the receiving space 112 is removed from the receiving space 112, the operating piece 223 is moved to the guide piece 126. On the other hand, since it passes the side far from the center 112a of the receiving space 112 in the width direction, the guide piece 126 is relatively pushed toward the side closer to the center 112a of the receiving space 112 in the width direction. Thereby, the configuration for passing the operating piece 223 farther from the center 112a of the receiving space 112 in the width direction than the guide piece 126 could be exemplified.

  Furthermore, the first surface 126c of the guide piece 126 is formed so as to be inclined so as to approach the center 112a of the receiving space 112 in the width direction as it goes in the counter-fitting direction. The first surface 223c of 223 is formed so as to be inclined away from the center 214 of the second contact 210 in the width direction as it goes in the anti-fitting direction of the second connector 200. When the piece 223 passes the guide piece 126 on the side close to the center 112a of the receiving space 112 in the width direction, the resistance is reduced and the guide piece 126 can pass smoothly. Similar actions and effects can be obtained when the above-described slope is formed on either the first surface of the guide piece or the first surface of the working piece. The second surface 126d of the guide piece 126 is formed so as to be inclined away from the center 112a of the receiving space 112 in the width direction as it goes in the fitting direction, and the second piece 126 of the operating piece 223 is formed. Since the two surfaces 223d are formed to be inclined so as to approach the center 214 of the second contact 210 in the width direction in the fitting direction of the second connector 200, the operating piece 223 is guided to the guide. When the piece 126 passes through the side far from the center 112a of the receiving space 112 in the width direction, the resistance is reduced and the piece 126 can pass smoothly. The same operation and effect can be obtained when the above-described inclination is formed on one of the second surface of the guide piece and the second surface of the working piece.

Among such various embodiments, the connector having the coupling detecting means of the first embodiment has the first locking portion 127a and can be elastically deformed, A second locking portion 224 that engages with the first locking portion 127a of the lever 127 when the connector is inserted into the other connector is provided to be distributed to both the connectors, and the first locking portion 127a and the above-mentioned When the engagement with the second locking portion 224 and the operating piece 223 are pulled out from the guide piece 126 in the anti-fitting direction of the first connector 100, the contact piece 113 tries to return to the original position. The contact portion 212 and the contact point 113a are configured to be in contact with each other at the same time. In this way, when the first connector 100 and the second connector 200 are completely fitted, the operating piece 223 is disengaged from the guide piece 126 and the contact piece 113 returns to the original position. In addition to the response due to the above, a response due to the engagement between the first locking portion 127a and the second locking portion 224 is obtained, so that the first connector 100 and the second connector 200 are also Is completely fitted.
