Description

  The present invention relates to an electrical connector.

  In general, electrical connectors are widely used as means for electrically connecting a wiring plate member such as a flexible printed circuit (FPC) to a main circuit board of an electrical device or the like in various electrical devices or the like. .

  The electrical connector includes a ZIF (Zero Insertion Force) type having an actuator that operates to firmly clamp or press the terminal of the wiring plate-like member inserted into the insulating housing by a contact that is conducted to the electrical circuit of the main circuit board. There is a non-ZIF type that does not have such an actuator.

In the ZIF type electrical connector, if the actuator is operated in a state where the terminal of the wiring plate member inserted in the insulating housing is not accurately positioned at the position corresponding to the contact, the following inconvenience may occur. There is.
(1) There is a possibility that a so-called half-fitted state in which the wiring plate member is fixed to the connector by the actuator in a state where the wiring plate member is not accurately inserted into the connector may occur. In the half-fitted state, normal conduction between the electric circuit of the main circuit board and the terminals of the wiring plate member may be hindered.
(2) When a force is applied to the wiring plate member in the removal direction, the wiring plate member can be easily removed from the connector.

  Therefore, a connector device is disclosed in which a lock member is engaged with a notch in the wiring plate-like member, the wiring plate-like member is temporarily held, and then the actuator is operated to hold the wiring plate-like member in the contact ( For example, see Patent Document 1).

  Hereinafter, electrical connectors according to embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the electrical connector 1 is mounted on a main circuit board 2 provided in an electrical device or an electronic device. On the main circuit board 2, a semiconductor chip for controlling an electric device or an electronic device is mounted, and an electric circuit including the semiconductor chip is formed. The electrical connector 1 electrically and physically connects an FPC (Flexible printed circuits) 3 to the main circuit board 2. “Electrically connected” means that a plurality of terminals 5 (5A, 5B) (see FIG. 2A) of the FPC 3 are electrically connected to an electric circuit mounted on the main circuit board 2. Further, “physically connected” means fixing the FPC 3 to the main circuit board 2.

  The FPC 3 is a flexible flat plate member (wiring plate member) on which wiring is formed. As shown in FIG. 2A, on the surface of the FPC 3, a plurality of conducting wires 4 extending in parallel to the y-axis direction constituting the wiring are arranged at equal intervals in the x-axis direction. Conductive terminals 5 (5A, 5B) are formed at the + y end of each conductor 4. The terminals 5A and 5B are alternately arranged along the x-axis direction. Since the width of the terminals 5A and 5B in the x-axis direction needs to be wider than that of the conducting wire 4, the terminals 5A and 5B are arranged so as to be shifted in the y-axis direction. The terminal 5B is arranged on the + y side with respect to the terminal 5A. Thus, the plurality of terminals 5 (5A, 5B) are formed at the ends of the plurality of conducting wires 4 extending in parallel to the y-axis direction formed in the FPC 3. In the drawings other than FIG. 2A, the conductive wire 4 and the terminal 5 of the FPC 3 are not shown.

  Further, as shown in FIGS. 2A, 2B, and 2C, at both ends in the arrangement direction (x-axis direction) of the plurality of terminals 5 (5A, 5B) in the vicinity of the + y end of the FPC 3. Is formed with a notch 6 as an engaging portion.

  In each figure, the arrangement direction of the plurality of terminals 5 (5A, 5B) in the FPC 3 is the x-axis direction, the insertion and removal directions of the FPC 3 with respect to the electrical connector 1 are the y-axis direction, and the thickness direction of the FPC 3 is the z-axis direction. Set the Cartesian coordinate system as the direction and refer to it as appropriate. The arrow direction of each axis is indicated by + (plus), and the opposite direction is indicated by-(minus).

  Returning to FIG. 1, the electrical connector 1 includes a housing 10, an actuator 11, and a pair of lock members 12 </ b> A and 12 </ b> B.

  The housing 10 is an insulating member made of, for example, synthetic resin. The FPC 3 is inserted into the housing 10. The housing 10 is provided with an insertion opening 20 into which the FPC 3 is inserted on the -y side. FIG. 3A shows a state in which the + y side end of the FPC 3 is positioned at the insertion opening 20. In the housing 10, the FPC 3 is inserted from the insertion opening 20 to the holding position. FIG. 3B shows a state in which the + y side end of the FPC 3 is inserted to the holding position. Thus, the FPC 3 is inserted into the housing 10 from the insertion opening 20 to the holding position.

  As shown in FIG. 4A, the housing 10 is provided with a plurality of contacts 13 (13A, 13B). The plurality of contacts 13 (13 </ b> A, 13 </ b> B) are conductive members that are electrically connected to the electric circuit of the main circuit board 2. The contact 13 (13A, 13B) is an elastic body. The plurality of contacts 13 (13A, 13B) are provided corresponding to the plurality of terminals 5 (5A, 5B) of the FPC 3 shown in FIG. Contacts 13A and contacts 13B are alternately arranged along the x-axis direction. The contact 13A is disposed corresponding to the terminal 5A, and the contact 13B is disposed corresponding to the terminal 5B. With the FPC 3 inserted in the holding position shown in FIG. 3B, the positions of the contact 13A and the terminal 5A, and the positions of the contact 13B and the terminal 5B are aligned. As shown in FIG. 4C, each contact 13A protrudes from the + y side portion of the housing 10 to the −z side. Each contact 13A is soldered to the electric circuit of the main circuit board 2 at the protruding portion. Each contact 13B protrudes from the −y side portion of the housing 10 to the −z side. Each contact 13B is soldered to the electric circuit of the main circuit board 2 at the protruding portion.

  The actuator 11 brings the contact 13 (13A, 13B) into contact with the plurality of terminals 5 (5A, 5B) of the FPC 3, and the contact 13 (13A, 13B) presses the plurality of terminals 5 (5A, 5B) to press the FPC 3. Is provided so as to sandwich and hold. The actuator 11 is also made of, for example, synthetic resin. 5A, 5B, and 5C show a state where the actuator 11 protrudes from the housing 10 in the + z direction. As shown in FIGS. 5B and 5C, the actuator 11 is provided with a cam rotation shaft 11A as a first rotation shaft. The cam rotation shaft 11A is a rotation shaft with a cam, and the arrangement direction (x-axis direction) of the plurality of contacts 13 (13A, 13B) is an axial direction. The actuator 11 is rotatably attached to the housing 10 via a cam rotation shaft 11A.

  The actuator 11 rotates from the rotational position shown in FIGS. 5A to 5C around the cam rotation shaft 11A around the x axis, and FIGS. 6A, 6B, and 6C. As shown in FIG. 6 (C), it rotates to a position protruding from the housing 10 in the + y direction. Hereinafter, the rotation position of the actuator 11 shown in FIGS. 5A to 5C is assumed to be the rotation position A (first rotation position), and the actuator 11 shown in FIGS. 6A to 6C is used. This rotational position is defined as rotational position B (second rotational position).

  As shown in FIGS. 5B and 5C, the shape of the contact 13 (13A, 13B) when viewed from the x-axis direction is an H shape. In the contact 13A, the two beams 13Aa and 13Ab extend in the + y direction, and the two beams 13Ac and 13Ad extend in the −y direction. In the contact 13B, the two beams 13Ba and 13Bb extend in the + y direction, and the two beams 13Bc and 13Bd extend in the −y direction. The beams 13Ab, 13Bb, 13Ad, and 13Bd are fixed to the housing 10. Further, as shown in FIG. 5B, a protruding contact portion 13Ae is provided at the tip of the beam 13Ac of the contact 13A, and as shown in FIG. 5C, the beam 13Bc of the contact 13B. A protruding contact portion 13Be is provided at the tip.

  The cam rotation shaft 11A of the actuator 11 is sandwiched between the beams 13Aa and 13Ab of the contact 13A and between the beams 13Ba and 13Bb of the contact 13B. Further, the FPC 3 inserted in the housing 10 is sandwiched between the beam 13Ac and the beam 13Ad of the contact 13A and between the beam 13Bc and the beam 13Bd of the contact 13B.

  When the actuator 11 rotates about the cam rotation shaft 11A from the rotation position A shown in FIGS. 5 (A) to 5 (C) to the rotation position B shown in FIGS. 6 (A) to 6 (C), the cam 11 The cam of the rotating shaft 11A also rotates. By this rotation, the diameter of the cam in the z-axis direction changes. Since the contact 13 (13A, 13B) is an elastic body as described above, when the diameter of the cam in the z-axis direction is increased, the space between the beam 13Aa and the beam 13Ab and the space between the beam 13Ba and the beam 13Bb are expanded. The space between the beam 13Ac and the beam 13Ad and the space between the beam 13Bc and the beam 13Bd become narrower. Accordingly, the contact portion 13Ae of the contact 13A comes into contact with the terminal 5A of the FPC 3, and the FPC 3 is sandwiched between the beam 13Ac and the beam 13Ad, and the contact portion 13Ae presses the terminal 5A. Further, the contact portion 13Be of the contact 13B comes into contact with the terminal 5B of the FPC 3, the FPC 3 is sandwiched between the beam 13Bc and the beam 13Bd, and the contact portion 13Be presses the terminal 5B. As a result, the contact 13 (13A, 13B) sandwiches the FPC 3.

  On the other hand, when the actuator 11 rotates from the rotational position B shown in FIGS. 6A to 6C to the rotational position A shown in FIGS. 5A to 5C, the cam of the cam rotating shaft 11A The diameter in the z-axis direction becomes shorter. As a result, the distance between the beams 13Aa and 13Ab and the distance between the beams 13Ba and Bb are narrowed, and the distance between the beams 13Ac and 13Ad is widened between the two beams 13Bc and 13Bd. Contact between the contact portion 13Ae and the contact portion 13Be and the terminal of the FPC 3 is released, and the contact 13 (13A, 13B) can be separated from the terminal 5 (5A, 5B) of the FPC 3.

  As shown in FIG. 7, the lock members 12A and 12B are provided so as to sandwich the FPC 3 from both ends in the arrangement direction (x-axis direction) of the plurality of terminals 5 (5A and 5B) in the FPC 3. The locking members 12A and 12B are rigid bodies formed of, for example, a metal plate material. The lock members 12A and 12B are formed around a rotation axis 12Aa and 12Ba as a second rotation axis whose axial direction is the thickness direction (z-axis direction) of the FPC 3 inserted up to the holding position shown in FIG. It can be rotated around an axis. The lock members 12A and 12B are connected to the housing 10 via the rotation shafts 12Aa and 12Ba.

  The locking members 12A and 12B are provided with three beams extending in the radial direction about the rotation shafts 12Aa and 12Ba.

  The first beam is the contact portions 12Ab and 12Bb. As shown in FIG. 7, the contact portions 12Ab and 12Bb extend in the radial direction about the rotation shafts 12Aa and 12Ba. The contact portions 12Aa and 12Bb are arranged so as to face each other. The abutting portions 12Ab and 12Bb abut on the + y side end of the FPC 3 inserted into the housing 10. In this state, when the FPC 3 further advances in the + y direction, the contact portions 12Ab and 12Bb rotate the lock members 12A and 12B as indicated by an arrow A around the rotation shafts 12Aa and 12Ba.

  The second beams are beams 12Ac and 12Bc. The beams 12Ac and 12Bc extend to the −y side so as to be orthogonal to the contact portions 12Ab and 12Bb. The lengths of the beams 12Ac and 12Bc are the same as the distance from the + y side end of the FPC 3 to the notch 6.

  Locking portions 12Ae and 12Be are formed at the ends of the beams 12Ac and 12Bc. The locking portion 12Ae extends in the direction of the FPC 3 from the tip of the beam 12Ac, and the locking portion 12Be extends in the direction of the FPC 3 from the tip of the beam 12Bc. The locking portions 12 </ b> Ae and 12 </ b> Be are provided to engage with the notch 6 of the FPC 3 inserted into the housing 10.

  The third beam is the release operation unit 12Ad, 12Bd. The release operation units 12Ad and 12Bd extend on the opposite side (+ y direction) of the beams 12Ac and 12Bc. The release operation portions 12Ad and 12Bd are set so that the tips thereof are at the y position substantially the same as the + y end of the housing 10. The release operation portions 12Ad and 12Bd are manually pushed in the direction of arrow B in FIG. 7 when the FPC 3 is removed from the housing 10, and the locking portions 12Ae and 12Be of the lock members 12A and 12B and the notches 6 of the FPC 3 and Is provided to release the engagement.

  Interlock portions 12Af and 12Bf are formed at the tips of the release operation portions 12Ad and 12Bd. The interlock portions 12Af and 12Bf extend in the direction of the actuator 11 from the release operation portions 12Ad and 12Bd. The interlock portions 12Af and 12Bf are positioned so as to interfere with the actuator 11 when the actuator 11 is rotated in a state in which the locking portions 12Ae and 12Be of the lock members 12A and 12B are not engaged with the notch 6 of the FPC 3. Is provided.

  The lock members 12A and 12B are rotated from the rotation position (third rotation position) shown in FIG. 7 around the rotation shafts 12Aa and 12Ba to the rotation position (fourth rotation) shown in FIGS. 8A and 8B. To position). The rotational position shown in FIG. 7 is defined as a rotational position C, and the rotational position illustrated in FIGS. 8A and 8B is defined as a rotational position D. When the FPC 3 is inserted from the insertion slot 20, the + y side end of the FPC 3 comes into contact with the contact portions 12Ab and 12Bb, and the lock members 12A and 12B positioned at the rotational position C are connected to the rotation shafts 12Aa and 12Ba. Turn to the rotational position D around the center. When the FPC 3 reaches the holding position shown in FIG. 3B, the lock members 12A and 12B rotate to the rotation position D, and the locking portions 12Ae and 12Be of the lock members 12A and 12B engage with the notches 6 of the FPC 3. The FPC 3 is locked by the lock members 12A and 12B.

  On the other hand, when the release operation portions 12Ad and 12Bd are operated so as to approach each other in the state shown in FIG. 8A, the lock members 12A and 12B rotate from the rotation position D (fourth rotation position). To the rotation position C (third rotation position). As the lock members 12A and 12B rotate, the engagement between the locking portions 12Ae and 12Be and the notch 6 of the FPC 3 is released, and the contact portions 12Ab and 12Bb move the FPC 3 from the holding position to the insertion opening 20 side. -Extrude in the y direction. When the locking members 12A and 12B reach the rotational position C (third rotational position), the engagement between the locking portions 12Ae and 12Be of the locking members 12A and 12B and the notch 6 of the FPC 3 is released, and the FPC 3 Extruded in the -y direction to the position shown in FIG.

  As described above, when the FPC 3 is inserted through the insertion slot 20, the electrical connector 1 allows the lock members 12A and 12B to be connected to the FPC 3 as shown in FIGS. 8A, 8B, and 8C. Is engaged. In the state shown in FIGS. 8A, 8B, and 8C, the actuator 11 remains in the rotational position A. As shown in FIGS. 9A, 9B, and 9C, the actuator 11 is rotated from the rotational position A (first rotational position) to the rotational position B (second rotational position). As a result, the side surface in the x-axis direction of the actuator 11 comes into contact with the interlock portions 12Af and 12Bf. As a result, the movement of the lock members 12A and 12B from the rotation position D (fourth rotation position) to the rotation position (third rotation position) is stopped, and the release operation portions 12Ad and 12Bd are operated to operate the lock member 12A. , 12B cannot be rotated. Further, even when the FPC 3 is forcibly pulled out in the -y direction, the lock members 12A and 12B are locked so that the lock members 12A and 12B cannot be rotated, and the lock state of the FPC 3 is strengthened. Maintained.

  Conversely, when the actuator 11 is rotated from the rotational position B to the rotational position A, the actuator 11 is interlocked with the locking members 12A and 12B located at the rotational position D as shown in FIG. Separated from 12Af and 12Bf. Accordingly, the lock members 12A and 12B can be rotated by operating the release operation portions 12Ad and 12Bd. When the lock members 12A and 12B are rotated from the rotation position D to the rotation position C, the engagement between the FPC 3 and the locking portions 12Ae and 12Be is released, and the FPC 3 can be removed.

  Further, as shown in FIGS. 10A and 10B, the interlock portions 12Af and 12Bf are located at the rotation position D (the fourth rotation position where the lock members 12A and 12B are engaged with the FPC 3). If not, the actuator 11 is prevented from rotating from the rotational position A to the rotational position B. As a result, when the FPC 3 is in a half-fitted state that is not locked by the lock members 12A and 12B, the actuator 11 rotates and prevents the contacts 13 (13A and 13B) from holding the FPC 3 in between. can do.

  Next, the operation of the electrical connector 1 will be described.

  FIG. 11 shows the flow of the operation of inserting the FPC 3 into the electrical connector 1. When inserting the FPC 3 into the electrical connector 1, first, the FPC 3 is inserted into the housing 10 from the insertion slot 20 as shown in FIG. 3A (step S1).

  Subsequently, when the + y side end portion of the FPC 3 comes into contact with the contact portions 12Ab and 12Bb of the lock members 12A and 12B, the lock members 12A and 12B are moved to the back side (+ y side) of the housing 10 as shown in FIG. (Step S2).

  Subsequently, when the FPC 3 reaches the holding position, as shown in FIGS. 8A, 8B, and 8C, the lock members 12A and 12B are engaged with the notches 6 of the FPC 3, and the FPC 3 Is locked by the locking members 12A and 12B (step S3).

  Subsequently, the actuator 11 is moved from the rotational position A shown in FIGS. 8A, 8B, and 8C as shown in FIGS. 9A, 9B, and 9C. Then, it is rotated to the rotation position B (step S4). Thereby, the insertion operation of the FPC 3 is completed. Here, for example, when the FPC 3 is inserted with an inclination with respect to the housing 10 and does not reach the holding position normally, the interlock portions 12Af and 12Bf of the lock members 12A and 12B are on the path of the actuator 11. Remain. For this reason, since the interlock parts 12Af and 12Bf stop the rotation of the actuator 11 from the rotation position A to the rotation position B, step S4 cannot be executed. In this case, the operator needs to operate the release operation portions 12Ad and 12Bd once to rotate the lock members 12A and 12B to remove the FPC 3 and then insert it again. In this way, it is possible to prevent a so-called half-fitted state where the FPC 3 is fixed to the electrical connector 1 in a state where the FPC 3 is not correctly inserted into the electrical connector 1. In addition, it is possible to prevent the FPC 3 from being easily disconnected from the electrical connector 1.

  In the state shown in FIGS. 8A and 8B, since the interlock portions 12Af and 12Bf of the lock members 12A and 12B are not in contact with the actuator 11, the lock members 12A and 12B can rotate. FPC3 is easy to come off. Therefore, in the electrical connector 1 of the present embodiment, as shown in FIGS. 9A and 9B, the actuator 11 can restrict the rotation of the lock members 12A and 12B, and the FPC 3 can be more firmly fixed. It is like that.

  Next, the operation when removing the FPC 3 will be described. FIG. 12 shows the flow of the FPC 3 removal operation.

  In order to remove the FPC 3, first, the actuator 11 is moved from the rotational position B shown in FIGS. 9A, 9B, and 9C to FIGS. 8A, 8B, and 8C. It is rotated to the rotational position A shown in FIG. 8C (step S11).

  Subsequently, the release operation units 12Ad and 12Bd are operated to rotate the lock members 12A and 12B from the rotational position D shown in FIGS. 8A and 8B to the rotational position C shown in FIG. S12). Meanwhile, the engagement between the locking portions 12Ae and 12Be and the cutout 6 of the FPC 3 is released, the contact portions 12Ab and 12Bb of the lock members 12A and 12B abut against the FPC 3, and the FPC 3 is shown in FIG. The state shown in FIG. 8 (B) is pushed out to the state shown in FIG.

  Subsequently, the FPC 3 is completely removed from the housing 10 (step S13). Thereby, the extraction operation of the FPC 3 is completed.

  As described above in detail, according to the present embodiment, when the locking portions 12Ae and 12Be of the pair of lock members 12A and 12B are not engaged with the FPC 3, each of the pair of lock members 12A and 12B. Interlock portions 12Af and 12Bf provided on the actuator stop the actuator 11 from rotating. As a result, only when the FPC 3 is accurately locked by the pair of lock members 12A and 12B, the terminal 5 (5A and 5B) of the FPC 3 is sandwiched and held in the contact 13 (13A and 13B) by the operation of the actuator 11. be able to. As a result, the FPC 3 can be held more accurately and firmly.

  Further, according to the present embodiment, the lock members 12A and 12B are located at the rotational position D where the lock members 12A and 12B are engaged with the notch 6 of the FPC 3, and the actuator 11 is connected to the contact 13 (13A and 13B) at the terminal 5 of the FPC 3. (5A, 5B), and when the contact 13 (13A, 13B) is in a position to press the terminal 5 (5A, 5B), the actuator 11 abuts against the interlock portions 12Af, 12Bf, and the lock member 12A, 12B does not rotate. In this way, the FPC 3 can be more firmly fixed by the lock members 12A and 12B.

  Further, according to the present embodiment, the abutting portions 12Ab and 12Bb are provided on the lock members 12A and 12B, and the lock members 12A and 12B are rotated as the FPC 3 is inserted into the housing 10 and goes deeper. When the FPC 3 reaches the holding position, the locking portions 12Ae and 12Be enter the notch 6 of the FPC 3 and engage with the notch 6. Further, when the lock members 12A and 12B are rotated by the operation of the release operation portions 12Ad and 12Bd, the contact portions 12Ab and 12Bb push the FPC 3 toward the insertion opening 20 side. In this way, it is possible to reduce the work burden on the operator when the FPC 3 is inserted or removed.

  The contact portions 12Ab and 12Bb of the lock members 12A and 12B extend in the radial direction from the rotation center of the rotation shafts 12Aa and 12Ba. In this way, the direction of the force transmitted between the contact portions 12Ab, 12Bb and the FPC 3 can be orthogonal to the radial direction of the rotary shafts 12Aa, 12Ba, so the rotational force of the lock members 12A, 12B can be increased. Can be maximized. As a result, the lock members 12A and 12B can be smoothly rotated by inserting or retracting the FPC 3.

  The electrical connector 1 according to the present embodiment includes release operation portions 12Ad and 12Bd for releasing the engagement between the notch 6 of the FPC 3 and the locking portions 12Ae and 12Be. In this way, the engagement between the notch 6 of the FPC 3 and the locking portions 12Ae and 12Be can be manually released without using a special jig.

  In the present embodiment, the thin plate-like lock members 12A and 12B are provided on both sides in the arrangement direction (x-axis direction) of the contacts 13 (13A and 13B), and are rotationally displaced in the xy plane. Can be reduced.

  The contact portions 12Ab and 12Bb may not be provided. When the contact portions 12Ab and 12Bb are not present, for example, after the FPC 3 is inserted into the holding position, the lock members 12A and 12B are manually rotated to allow the locking portions 12Ae and 12Be to enter the notch 6 of the FPC 3. You may do it. When the FPC 3 is removed, the release operation portions 12Ad and 12Bd are operated to release the engagement between the notch 6 of the FPC 3 and the locking portions 12Ae and 12Be, and then the FPC 3 is extracted.

  Further, in the electrical connector 1 according to the above embodiment, the contacts 13 (13A, 13B) having different shapes are used, but the present invention can be similarly applied even if the contacts having the same shape are used. Is possible.
