In addition, the protrusion 11 is formed with an inclined surface 11A.

When the plug-side connector 1 and the board-side connector 2 are fitted together, the connector main body 3 and part of the pull bar 4 of the plug-side connector 1 are inserted into the recess 9 of the board-side connector 2 . At this time, the tip of the rotating shaft portion 6 of the pull bar 4 is guided by the inclined surface 11A of the protrusion 11 and is elastically displaced toward the outside of the connector main body 3 while riding on the protrusion 11 and advancing in the recess 9. When the tip of the rotating shaft 6 gets over the protrusion 11, the tip of the rotating shaft 6 is accommodated in the pull bar accommodating groove 10, and the plug-side connector 1 and the board-side connector 2 are fitted to each other, as shown in FIG. combined. At this time, since the tip of the rotating shaft portion 6 is caught by the protrusion 11, the plug-side connector 1 is prevented from coming off from the board-side connector 2, and the mated state of the plug-side connector 1 and the board-side connector 2 is locked. state.

As shown in FIG. 36, the pull bar 4 rotates about the rotation shaft 6 with respect to the connector main body 3 so that the arm 5 rides on the rib 8 of the connector main body 3 from the state in which the mated state is locked. As a result, the rotating shaft portion 6 is displaced toward the outside of the connector main body 3 so that the rotating shaft portion 6 is no longer caught on the protrusion 11, and the lock of the fitted state between the plug-side connector 1 and the board-side connector 2 is released. be. In this state, for example, the user can pull out the plug-side connector 1 from the board-side connector 2 .

As described above, in Patent Document 1, the mated state of the plug-side connector 1 and the board-side connector 2 is locked. 3 so that the arms 5 of the pull bar 4 ride on the ribs 8, thereby elastically displacing the rotation shafts 6 to unlock the mated state of the plug-side connector 1 and the board-side connector 2. 1, the user needs to perform two operations in different directions, that is, to pull out the plug-side connector 1 from the board-side connector 2 . Therefore, the invention of Patent Document 1 has room for improvement, such as adding a mechanism for ejecting the plug-side connector 1 from the board-side connector 2, for example.

A mechanism for ejecting one of two mated connectors is disclosed, for example, in Patent Document 2. As shown in FIG. 37, the connector 12 disclosed in Patent Literature 2 includes a seesaw member 14 that rotates about the projecting portion 13 as a fulcrum, a push button member 15 for pushing one end of the seesaw member 14, a seesaw member 14 and has a pushing member 17 for pushing a mating connector 16 fitted with the connector 12 . When the user presses the push button member 15 , the seesaw member 14 rotates about the projecting portion 13 as a fulcrum, thereby displacing the pushing member 17 in the direction opposite to the direction in which the user presses the push button member 15 . As a result, the pushing member 17 pushes the mating connector 16 and the mating connector 16 is ejected from the connector 12 .

JP 2005-267977 A JP-A-5-74518

Here, a mechanism for locking the mated state of two connectors as disclosed in Patent Document 1 and a mechanism for two connectors that are fitted to each other as disclosed in Patent Document 2 It is envisaged to combine the two ejecting mechanisms with each other. In this case, for example, after extending the arm portion 5 of the pull bar 4 in Patent Document 1, the rotating shaft portion 6 is arranged in the middle portion of the arm portion 5, and the tip portion of the extended arm portion 5 is arranged in Patent Document 2. A configuration is assumed in which the pushing member 17 is arranged in . According to this configuration, for example, when the rotating shaft portion 6 of the pull bar 4 is caught on the mating connector, the mated state with the mating connector is locked, and when the mating connector is removed from this state, the pull bar 4 is rotated. As a result, the rotating shaft part 6 is detached from the mating connector, and the mating connector is pushed by the pushing member 17 arranged at the tip part of the arm part 5, so that the mating connector can be ejected.

However, in this configuration, it is necessary to extend the arm portion 5 of the pull bar 4, and there is a problem that the size of the connector increases accordingly.
Further, when the mating state with the mating connector is locked, the mating connector cannot be displaced in the mating direction with respect to the mated connector. The push member 17 cannot come into contact with the mating connector until the lock of the mating state with the mating connector is released by rotating the connector by 100 degrees, and the pushing member 17 needs to be displaced by a predetermined distance in the mating direction. There is Further, the push-out member 17 needs to be displaced by a predetermined distance until the push-out member 17 pushes out the mating connector and the mating connector is ejected. Therefore, according to such a configuration, there is a problem that the size of the connector increases in the fitting direction as well.

The second insulator mounting portion 34A has a shape in which a pair of third plate-shaped portions 91 extending along the YZ plane are connected to each other at the ends in the -Z direction. A pair of locked portions 91A are formed by insertion holes into which the pair of lock portions 54 are inserted.

Next, operation of the receptacle connector 21 according to the embodiment will be described. 20, the receptacle connector 21 is mounted on the first substrate S1 parallel to the XY plane, and the plug connector 31 is mounted on the XY plane. An example of mounting on a parallel second substrate S2 will be described. In the receptacle connector 21, three first soldering portions 89 of the first metal member 44 are fixed to fixing pads (not shown) of the first substrate S1, and a plurality of first contacts 42 are connected to a plurality of not shown fixing pads of the first substrate S1. It is mounted on the first substrate S1 by being connected to the connection pad. The plug connector 31 has a second soldering portion 34C of the second metal member 34 fixed to a fixing pad (not shown) of the second substrate S2, and a plurality of second contacts 32 are connected to a plurality of not shown fixing pads of the second substrate S2. It is mounted on the second substrate S2 by being connected to the connection pads.

In this manner, the receptacle connector 21 mounted on the first substrate S1 and the plug connector 31 mounted on the second substrate S2 are connected to each other along the Z direction. At this time, the accommodated portion 33B of the second insulator 33 is accommodated in the plug connector accommodating portion 71 of the first insulator 43, and the inner projecting portion 77 of the first insulator 43 is accommodated in the accommodated portion 33B. , the plug connector 31 is fitted to the connector main body 41 of the receptacle connector 21, and the plurality of first contacts 42 and the corresponding plurality of second contacts 32 are electrically connected to each other. As a result, the first board S1 on which the receptacle connector 21 is mounted and the second board S2 on which the plug connector 31 is mounted are also electrically connected to each other. Thus, the receptacle connector 21 according to the embodiment can be used as a so-called board-to-board connector.

Further, by connecting the receptacle connector 21 and the plug connector 31 to each other in this manner, a connector assembly 101 including the receptacle connector 21 and the plug connector 31 is constructed as shown in FIG. For the sake of explanation, the +Y direction side of the receptacle connector 21 and the plug connector 31 will be described below, but the same explanation applies to the -Y direction side.

In a state in which the connector main body 41 and the plug connector 31 are engaged with each other and the lever 51 is not operated by the user to move, the pair of elastic members 61 apply an elastic force in the +Z direction to the +Y direction ends of the pair of arms 52 . acts to push up the operating portion 53 in the +Z direction. As a result, the pair of rod-shaped members 87 abut against the ends of the pair of elongated holes 56 formed in the pair of arms 52 in the -Z direction, and the pair of locks 54 are aligned with the pair of openings 86 for locks and the plug connector. The locked portion 91A of 31 and the state of being inserted into the second insulator side insertion hole 33G are maintained.

FIG. 22 shows a cross-sectional view of the connector assembly 101 cut along the XZ plane passing through the projection 88 of the first metal member 44. As shown in FIG. The pair of arm portions 52 of the lever 51 are located above the pair of projections 88, that is, on the +Z direction side, and the pair of arm portions 52 and the pair of projections 88 are arranged at positions separated from each other.

FIG. 23 shows a cross-sectional view of the connector assembly 101 cut along the XZ plane passing through the locking portion opening 86 of the first metal member 44 . The pair of lock portions 54 are inserted into the second insulator side insertion hole 33G through the pair of lock portion openings 86 of the first metal member 44 and the pair of locked portions 91A of the second metal member 34 . As a result, the mated state between the connector main body 41 and the plug connector 31 is locked. For example, even when the plug connector 31 is pulled out from the connector main body 41, that is, when a force acting in the +Z direction acts, the −Z direction ends of the pair of locked portions 91A are aligned with the −Z direction ends of the pair of locking portions 54. , the movement of the plug connector 31 in the +Z direction is suppressed.

When the connector main body 41 and the plug connector 31 are unlocked and the plug connector 31 is ejected from the connector main body 41, as shown in FIG. Movement operation is performed in the Z direction. A pair of lock portion openings 86 of the first metal member 44 serve as bearings for the pair of lock portions 54, and the lever 51 rotates within the YZ plane with respect to the connector body 41 with the pair of lock portions 54 as the first rotation center. do. At this time, the pair of long holes 56 are displaced in the -Z direction as the lever 51 rotates, and the pair of rod-like members 87 abut against the ends of the pair of long holes 56 in the +Z direction. Also, the pair of projections 88 are arranged on the locus of rotation of the pair of arm portions 52, and as shown in FIG. It advances in the Z direction and rides on the pair of protrusions 88 . As a result, the pair of arm portions 52 are pushed apart so as to move away from each other along the X direction.

When the pair of arms 52 are elastically displaced in this manner and are pushed apart along the X direction, the pair of locks 54 are also elastically displaced by the arms 52 as shown in FIG. Along with this, they are displaced away from each other along the X direction and come out of the pair of locked portions 91A and the second insulator side insertion hole 33G. As a result, the plug connector 31 can move in the +Z direction with respect to the connector body 41, and the locked state between the connector body 41 and the plug connector 31 is released. At this time, the +Z direction ends of the inclined portions 58 of the pair of lock portions 54 are out of the lock portion openings 86, and as shown in FIG. It hits the +Z direction end of the hole 56 .

When the operating portion 53 of the lever 51 is further moved in the -Z direction by the user, the +Z direction ends of the pair of elongated holes 56 of the lever 51 serve as bearings for the pair of rod members 87, as shown in FIG. , the lever 51 rotates in the YZ plane with respect to the connector main body 41 while being received by the pair of rod members 87 with the +Z direction ends of the pair of elongated holes 56 as the second rotation center.

28, when the lever 51 rotates about the +Z direction end of the pair of elongated holes 56 as the second rotation center, the pair of lock portions 54 are arranged such that the pair of inclined portions 58 are connected to the pair of lock portions as shown in FIG. The pair of lock portions 54 are guided to be elastically displaced away from each other along the X direction by being pressed against the +Z direction end portion of the opening 86 for the unit. As a result, the pair of lock portions 54 are disengaged from the pair of lock portion openings 86, the -Y direction end portion of the lever 51 is further moved in the +Z direction, and the push-out portion 34B of the plug connector 31 is pushed out from the pair of lock portion openings 86. The plug connector 31 is ejected from the connector main body 41 by being pushed in the +Z direction by the ejection portion 55 .

In this way, only by the user moving the operating portion 53 in the -Z direction, the lock of the mated state between the connector main body 41 and the plug connector 31 is released, and the plug connector 31 is ejected from the connector main body 41. be able to. Therefore, for example, when the plug connector 31 is removed from the connector main body 41 in a state in which the connector main body 41 and the plug connector 31 are locked in a mated state, the connector main body 41 and the plug connector 31 are in a mated state. and the ejection of the plug connector 31 are not required to be performed separately. The plug connector 31 can be easily ejected.

29, when the plug connector 31 is detached from the connector body 41, the pair of elastic members 61 are compressed so that the first end 63 and the second end 64 come close to each other. The lever 51 is rotated in a direction in which the first end portion 63 and the second end portion 64 move away from each other, that is, in a direction opposite to the direction in which the operation portion 53 is pressed by the user. In addition, an elastic force acts on the pair of arm portions 52 .

Therefore, for example, when the user releases the operation portion 53 and the -Z direction force from the user stops acting on the operation portion 53, as shown in FIG. The pair of rod members 87 abut against the −Z direction ends of the pair of long holes 56 and the +Z direction ends of the pair of arms 52 contact the pair of stoppers 85 . When the ends of the pair of arms 52 in the +Z direction come into contact with the pair of stoppers 85, the ends of the pair of arms 52 on the lock portion 54 side move in the direction in which the plug connector 31 is ejected from the connector main body 41, that is, +Z. direction is prevented from moving. Further, when the pair of arms 52 receive further elastic force from the pair of elastic members 61 from this state, the -Z direction ends of the pair of elongated holes 56 act as bearings for the pair of rod-like members 87, and the lever 51 is moved into the pair of With the -Z direction ends of the pair of long holes 56 against which the rod-shaped members 87 abut as the third rotation center, in the direction opposite to the direction of the movement operation of the operation part 53, that is, according to the movement operation of the operation part 53 It rotates elastically with respect to the connector main body 41 in the direction opposite to the rotation direction of the lever 51 .

As a result, as shown in FIG. 31, the pair of lock portions 54 are inserted into the pair of lock portion openings 86 of the first metal member 44, and the position of the lever 51 is changed so that the connector main body 41 and the plug connector 31 are engaged with each other. position before mating.
As described above, the pair of elastic members 61 allows the lever 51 to automatically rotate elastically and return to the initial position simply by releasing the user's hand from the operation unit 53 . Therefore, it is not necessary to return the position of the lever 51 to the initial position, and the user's trouble can be reduced.

As described above, according to the receptacle connector 21 according to the embodiment, the user can easily unlock the mated state of the connector main body 41 and the plug connector 31 simply by moving the operating portion 53 in the -Z direction. , the plug connector 31 can be ejected.

Further, as shown in the conceptual diagram of FIG. 32, the lever 51 is rotated by a predetermined angle A1 around the lock portion 54 as the first rotation center C1 until the mating state of the connector main body 41 and the plug connector 31 is unlocked. rotates to unlock the mated state of the connector main body 41 and the plug connector 31, the rotation center of the lever 51 moves from the lock portion 54, which is the first rotation center C1, to the second rotation center C2. Move to the +Z direction end of hole 56 . Further, when the lever 51 rotates by a predetermined angle A2 with the +Z direction end of the elongated hole 56 as the second rotation center C2, the eject portion 55 pushes the plug connector 31 in the +Z direction, causing the plug connector 31 to move toward the connector main body. 41 is ejected. At this time, the ejector 55 moves by a predetermined distance L2 along the +Z direction.

Here, for example, as shown in the conceptual diagram of FIG. Assume a connector having a locking portion 114 disposed in the middle of the portion 111 and serving as the rotation center C of the arm portion 111 .

When the arm portion 111 rotates around the lock portion 114 by a predetermined angle A3, the arm portion 111 is projected. , the locking portion 114 is elastically displaced so as to be disengaged from the mating connector, thereby unlocking the mating state of the connector and the mating connector. At this time, the ejection portion 113 is displaced by a predetermined distance L5 in a direction opposite to the mating direction of the connector and the mating connector, and contacts the mating connector. When the arm portion 111 further rotates by a predetermined angle A4 around the lock portion 114 as the center of rotation C, the ejection portion 113 pushes the mating connector, and the mating connector is ejected from the connector. At this time, the ejection portion 113 is further displaced by a predetermined distance L6 in a direction opposite to the mating direction of the connector and the mating connector.

According to this connector, when the operation portion 112 is moved by the user, the mated state of the connector and the mating connector can be unlocked and the mating connector can be ejected from the connector. In addition to the distance L3 between 112 and the lock portion 114, which is the center of rotation C, the arm portion 111 needs to be extended by the distance L4 between the lock portion 114 and the ejection portion 113. Therefore, the arm portion 111 is extended. It is assumed that the size of the connector will be increased by the distance L4.

Further, when the mating state of the connector and the mating connector is locked, the mating connector cannot move in the direction opposite to the mating direction with respect to the connector. , the arm portion 111 cannot contact the mating connector until the arm portion 111 rotates by a predetermined angle A3 about the rotation center C of the locking portion 114 and the mated state between the connector and the mating connector is unlocked. It must be displaced in the direction opposite to the mating direction by a predetermined distance L5. Furthermore, the ejection portion 113 must be further displaced in the direction opposite to the mating direction by a predetermined distance L6 until the mating connector is ejected from the connector. Therefore, it is assumed that the size of the connector will be increased also in the fitting direction.
