  1 to 7, the connector 1 according to the embodiment of the present invention has a receiving portion 6 that is open at the front end 2. The receiving portion 6 can receive the front end of an FPC (connecting member: described later) inserted toward the rear end 4 (rearward or in the + X direction) in the front-rear direction (X direction). The connector 1 includes a first contact (contact) 10 made of a conductor, a second contact (contact) 20 made of a conductor, a holding member 30 made of an insulator, and a shell (conductive member) 40 made of a conductor. And an actuator 50 made of an insulator and a shield member 60 made of a conductor.

  Specifically, as shown in FIG. 17, a special FPC (connecting member) 80 can be connected to the connector 1 according to the present embodiment, and as shown in FIG. An FPC 80A having a normal band shape can also be connected. Note that a normal FPC 80A may or may not have a ground pattern.

  14 to 16, the special FPC 80 of the present embodiment includes a signal layer 90, a ground layer 92, a first insulating layer 94, a second insulating layer 95, and a third insulating layer 96. I have. The first insulating layer 94 is sandwiched between the signal layer 90 and the ground layer 92. The signal layer 90 is sandwiched between the first insulating layer 94 and the second insulating layer 95. The ground layer 92 is sandwiched between the first insulating layer 94 and the third insulating layer 96. In the signal layer 90, a plurality of terminals 83 and a plurality of signal lines 84 respectively corresponding to the terminals 83 are formed. The terminal 83 is located closer to the end portion 82 than the signal line 84. The signal line 84 extends from the corresponding terminal 83. The ground layer 92 is composed of a ground pattern 86 made of a uniform conductive film. A part of the ground pattern 86 is exposed as an exposed portion 88 as described later.

  As shown in FIG. 14, a terminal exposed region 85 is provided at the end portion 82 of the FPC 80, and the terminal 83 is disposed in the terminal exposed region 85. In the present embodiment, the terminals 83 are divided into two groups, one corresponding to the first contact 10 and one corresponding to the second contact 20. The terminals 83 corresponding to the first contacts 10 and the terminals 83 corresponding to the second contacts 20 are alternately arranged in the width direction (Y direction) and the length direction (X direction) of the FPC 80.

  As shown in FIGS. 14 and 15, the FPC 80 has a protruding portion 87 at a position away from the end portion 82 in the length direction of the FPC 80. As can be understood from FIG. 14, the overhang portion 87 is located farther from the end portion 82 than the terminal exposed region 85. Further, the overhang portion 87 projects outward in the width direction of the FPC 80. Therefore, the FPC 80 is wider than the terminal exposed region 85 in the portion including the overhang portion 87.

  As shown in FIG. 15, an exposed portion 88 is formed at the tip of the overhang portion 87. In the present embodiment, the surface where the exposed portion 88 is formed is the back surface of the surface where the terminal exposed region 85 is formed. However, the present invention is not limited to this, and the exposed portion 88 may be formed on the same surface as the surface on which the terminal exposed region 85 is formed. The ground pattern 86 is exposed at the exposed portion 88. As is clear from the relationship between the overhang portion 87 and the terminal exposed region 85, the exposed portion 88 is located farther from the end portion 82 of the FPC 80 than the terminal 83 in the length direction of the FPC 80, and It is located outside the terminal 83 in the width direction.

  As can be understood from FIGS. 6 and 7, the holding member 30 holds the first contact 10 and the second contact 20. As shown in FIG. 7, the first contact 10 has an upper contact portion (contact portion) 11, a lower contact portion (contact portion) 12, and a fixing portion 13. The upper contact portion 11 and the lower contact portion 12 are located in the receiving portion 6 and face each other in the vertical direction (Z direction). The fixing portion 13 of the first contact 10 is located on the rear end 4 side of the connector 1. As shown in FIG. 6, the second contact 20 has an upper contact portion (contact portion) 21, a lower contact portion (contact portion) 22, and a fixing portion 23. The upper contact portion 21 and the lower contact portion 22 are located in the receiving portion 6 and face each other in the vertical direction (Z direction). The fixing portion 23 of the second contact 20 is located on the front end 2 side of the connector 1. That is, the contact in which the fixing portion 13 is located from the rear end 4 is the first contact 10, and the contact in which the fixing portion 23 is located from the front end 2 is the second contact 20. In other words, the contact in which the fixing portion 13 is located behind the upper contact portion 11 and the lower contact portion 12 is the first contact 10, and the fixing portion 23 is more than the upper contact portion 21 and the lower contact portion 22. The contact located in front is the second contact 20. Referring also to FIG. 14, when the FPC 80 is inserted into the receiving portion 6 so that the terminal 83 is on the upper side, the upper contact portions 11, 21 are connected to the terminal 83. When the FPC 80 is inserted into the receiving portion 6 so as to be on the lower side, the lower contact portions 12 and 22 are connected to the terminal 83. As described above, in the present embodiment, the FPC 80 can be connected even if it is reversely inserted into the connector 1.

  As shown in FIG. 5, the holding member 30 is provided with a rotation preventing portion 32. The rotation preventing part 32 constitutes a side wall of the receiving part 6. Specifically, it is located outside the upper contact portions 11 and 21 and the lower contact portions 12 and 22 of the first contact 10 and the second contact 20 in the width direction. In particular, in the present embodiment, in the width direction, the distance between the rotation preventing portions 32 is slightly larger than the size (width) of the terminal exposed region 85 of the FPC 80. As understood from FIGS. 5 and 17, when the FPC 80 is received in the receiving portion 6, the movement of the FPC 80 in the horizontal plane (XY plane) is substantially restricted only in the front-rear direction, and the FPC 80 rotates in the horizontal plane. Can be avoided.

  As shown in FIGS. 12 and 13, the shell 40 includes a main plate portion 41, two side portions 42, two shell connection portions 43, four hold downs 44, and two sets of upper connection portions (shields). Connection portion) 45 and lower connection portion (shield connection portion) 46.

  The main plate portion 41 covers most of the holding member 30. As can be understood from FIGS. 1, 2, and 5, the fixing portion 13 of the first contact 10 is located behind (+ X side) the main plate portion 41, and the fixing portion 23 of the second contact 20 is It is located in front of the main plate portion 41 (−X side). The fixing portion 23 of the second contact 20 is visible from above (+ Z side) in a state where the FPC 80 is not connected to the connector 1. Therefore, when the connector 1 is mounted and fixed on an object (not shown), the connection state of the fixing portion 23 to the object can be easily confirmed.

  The side portions 42 are located on both sides of the main plate portion 41 in the width direction. As can be understood from FIG. 9, the shell connecting portions 43 respectively extend downward from the side portions 42 (−Z direction). The shell connecting portion 43 is located on the rear side (+ X side) from the main plate portion 41.

  As shown in FIGS. 1 and 12, the hold down 44 is provided so as to be continuous with the side portion 42, and is located outside the holding member 30 in the width direction. The hold down 44 is connected to a ground portion (not shown) formed on the object when the connector 1 is mounted on an object (not shown) such as a circuit board. In other words, the shell (conductive member) 40 is connected to a ground portion (not shown) formed on the object when the connector 1 is mounted on the object (not shown).

  The upper connection portion 45 and the lower connection portion 46 are provided so as to be continuous with the side portion 42. The upper connection portion 45 and the lower connection portion 46 of each set face each other in the vertical direction. The upper connection portion 45 and the lower connection portion 46 are located in front of the main plate portion 41 (−X side). As understood from FIG. 5, the upper connection portion 45 and the lower connection portion 46 are located on the front side of the upper contact portions 11 and 21 and the lower contact portions 12 and 22 of the first contact 10 and the second contact 20. And located outside the upper contact portions 11 and 21 and the lower contact portions 12 and 22 in the width direction. Furthermore, the upper connection part 45 and the lower connection part 46 are located in front of the rotation prevention part 32. In other words, the rotation prevention part 32 is located behind the upper connection part 45 and the lower connection part 46. As can be understood from FIGS. 8 and 13, the upper connection portion 45 is a spring contact, and the lower connection portion 46 is a dowel (projection).

  As understood from FIGS. 5, 15, and 17, when the FPC 80 is inserted into the receiving portion 6, one of the upper connection portion 45 and the lower connection portion 46 is connected to the exposed portion 88 of the ground pattern 86. Specifically, when the FPC 80 is inserted into the receiving portion 6 so that the exposed portion 88 is on the lower side, the lower connection portion 46 is connected to the exposed portion 88 and the exposed portion 88 is received on the upper side. When the FPC 80 is inserted into the part 6, the upper connection part 45 is connected to the exposed part 88. In any case, sufficient connection can be obtained by utilizing the spring force of the upper connection portion 45.

  As understood from FIGS. 1 to 3, the actuator 50 is supported by the holding member 30 so as to be in an open state and a closed state. As shown in FIGS. 6 and 7, the actuator 50 is provided with a cam 51. When the actuator 50 is in the open state, the cam 51 does not apply much force to the first contact 10 and the second contact 20. Therefore, the end portion 82 of the FPC 80 can be easily received in the receiving portion 6 of the connector 1. On the other hand, when the actuator 50 is in the closed state, the cam 51 applies a force to the first contact 10 and the second contact 20 and the distance between the upper contact portions 11, 21 and the lower contact portions 12, 22. Try to narrow. Therefore, when the end portion 82 of the FPC 80 is received by the receiving portion 6, the upper contact portions 11, 21 or the lower contact portions 12, 22 are pressed against the terminal 83 of the FPC 80, and a connection between them is ensured. Is done. In particular, the connector 1 according to the present embodiment is of a back flip type, and as can be understood from FIGS. 1 to 3, the actuator 50 can be closed by tilting the actuator 50 backward. .

  As shown in FIGS. 6, 7, and 11, the shield member 60 is embedded in the actuator 50. The illustrated shield member 60 is made of an elongated metal plate, and is located above (+ Z side) the fixing portion 13 of the first contact 10 when the actuator 50 is in a closed state. As understood from FIGS. 9 to 11, when the actuator 50 is in the closed state, the shield member 60 is connected to the shell connecting portion 43 of the shell 40. In other words, when the actuator 50 is in the closed state, the shield member 60 is connected via the shell 40 to the ground portion of an object (not shown) on which the connector 1 is mounted. Thereby, the fixing portion 13 of the first contact 10 is electromagnetically protected by the shield member 60.

  When the end portion 82 of the FPC 80 is inserted into the receiving portion 6 of the connector 1 having the structure as described above, the lower connection portion 46 or the upper connection portion 45 is connected to the exposed portion 88 of the FPC 80. As a result, the ground pattern 86 is connected to the ground portion of the object (not shown) via the shell 40, and high shielding characteristics can be obtained. Further, when the actuator 50 is tilted rearward to be in the closed state, the upper contact portions 11 and 21 or the lower contact portions 12 and 22 of the first contact 10 and the second contact 20 are connected to the terminal 83 of the FPC 80. As described above, the connector 1 of the present embodiment can be connected to the FPC 80 having the ground pattern 86, and can appropriately cope with the increase in signal speed.

  As understood from FIG. 18, the upper connection portion 45 and the lower connection portion 46 are located outside the general FPC 80A in the width direction, and therefore do not hinder the connection between the general FPC 80A and the connector 1. . That is, the connector 1 according to the present embodiment can be connected to a general band-shaped FPC 80A.

  In addition, the upper connection portion 45 and the lower connection portion 46 are outside the upper contact portions 11 and 21 and the lower contact portions 12 and 22 in the width direction, and are the upper contact portions 11 and 21 and the lower contact portions 12 and 22. Since the connector 1 is located behind the connector 22, the upper connection portion 45 and the lower connection portion 46 can be provided to the connector 1 without particularly increasing the size of the connector 1.

  Furthermore, since the upper connection portion 45 and the lower connection portion 46 are arranged at the above-described positions, the shell 40 does not need to cross over the fixing portion 23 of the second contact 20, so that the connector 1 is viewed from above. In this case, the fixing portion 23 of the second contact 20 can be visually recognized. That is, when the fixing portion 23 is connected to an object (not shown) such as a circuit board by soldering, it is possible to confirm whether soldering is good or bad.

  Although the connector 1 according to the embodiment has been described in detail as an example, the present invention is not limited to this, and various modifications and applications are possible.

  For example, in the above-described embodiment, the connecting member connected to the connector 1 is the FPC 80. However, the connecting member may not be the FPC 80 as long as it is a plate-like or sheet-like connecting member. For example, the connecting member may be FFC.

  Moreover, although the connector 1 mentioned above was provided with the actuator 50, this invention is applicable also to the type of connector which does not have an actuator.

  Furthermore, although the connector 1 described above is of a back flip type in which the actuator 50 is tilted rearward to be in a closed state, the present invention can also be applied to a front flip type. However, since the back flip type connector 1 can adopt a configuration in which the main plate portion 41 of the shell 40 covers most of the holding member 30, the connector is a back flip type when high shielding characteristics are required. Preferably there is.

  The shell 40 described above covers most of the holding member 30, but depending on the required shield characteristics, a hold-down member (a member having a side portion 42, a hold-down 44, etc.) having a structure in which the main plate portion 41 is omitted. ) May be attached to both ends of the holding member 30. In this case, the upper connection portion 45 and the lower connection portion 46 are provided on the hold-down member.

  The connector 1 described above includes two types of contacts, the first contact 10 and the second contact 20, but may include only one of the first contact 10 or the second contact 20. However, in order to cope with a narrow pitch, the connector 1 preferably includes two types of contacts, the first contact 10 and the second contact 20.

  The connector 1 described above includes the shield member 60. However, the shield member 60 is omitted when the connector 1 does not have the first contact 10 or is allowed in consideration of the required shield characteristics. It is good to do.

  The connector 1 described above includes the upper contact portions 11 and 21 and the lower contact portions 12 and 22, the upper connection portion 45 and the lower connection portion 46 in order to allow the FPC 80 to be reversely inserted. If reverse insertion is not required, one of the upper contact portions 11 and 21 and the lower contact portions 12 and 22 and the shield connection of either the upper connection portion 45 or the lower connection portion 46 are used. Only the portion can be provided in the connector 1.

  In the embodiment described above, the upper connection portion 45 is a spring contact and the lower connection portion 46 is a dowel (projection). However, the upper connection portion 45 is a dowel (projection) and the lower connection portion 46 is a spring. It is good also as a contact, and it is good also considering both as a spring contact.

  In addition, when it is not possible to reversely insert the FPC 80 into the connector 1, one of the upper connection portion 45 and the lower connection portion 46 that is connected to the exposed portion 88 is a spring contact, and the other is flattened. Also good.

  Although the above-described rotation prevention unit 32 is formed as a part of the holding member 30, the rotation prevention unit 32 may be configured by another member instead of a part of the holding member 30. Further, if the movement of the FPC 80 can be restricted by other means, the rotation preventing unit 32 may be omitted.

  The FPC 80 described above includes only one signal layer 90 as shown in FIG. 16, but, for example, two signal layers may be provided for the FPC.

  In the FPC 80 described above, the exposed portion 88 is formed on the back surface of the surface on which the terminal 83 is formed, but the surface on which the exposed portion 88 is formed may be the same surface as the surface on which the terminal 83 is formed.
