Description

  The present invention relates to an electrical connector.

  Various electric devices or electronic devices (personal computers, smartphones or tablets) are typified by a flexible printed circuit board (FPC) or a flexible flat cable (FFC) to transmit signals between circuit boards. A flexible flat wiring board is used. An electrical connector is widely used for the connection between the wiring board and the circuit board.

  The electrical connector includes a ZIF (Zero Insertion Force) type and a NON-ZIF type. The ZIF type electrical connector can insert the wiring board with a low insertion force, and the actuator can clamp or press the contact of the wiring board relatively firmly by the actuator. On the other hand, the NON-ZIF type electrical connector requires a strong holding force to prevent the FPC or FFC from being inadvertently removed, and thus requires a high insertion force, while no actuator is required. Therefore, it is possible to reduce the size and height.

  In the NON-ZIF type electrical connector in which the narrow pitch and the low profile are realized, it is necessary to increase the holding force with respect to the wiring board by some method. As the wiring boards used are becoming thinner and easier to disconnect from the electrical connector, there is an increasing demand for strengthening this holding power.

  In order to improve the holding power of the wiring board, an electrical connector provided with a lock mechanism is disclosed (for example, see Patent Document 1). In the electrical connector of Patent Document 1, a lock member is provided on a shell that rotates with respect to the housing. When the wiring board is inserted into the housing and the shell is rotated and brought into contact with the housing, the lock member enters the inside through the insertion hole of the housing and is locked to the wiring board.

JP 2008-192574 A

  In the NON-ZIF type electrical connector, which is reduced in size and height, the wiring board is also thinned, so that the holding power of the wiring board is reduced, and the wiring board may be unintentionally removed. Therefore, it is necessary to provide a lock mechanism or the like to improve the holding power of the wiring board. When the lock mechanism is provided, when the wiring board is removed from the connector, a complicated operation of removing the wiring board while performing the unlocking operation of the locking mechanism is required. Further, in the unlocking operation, a load may be applied to the circuit board due to the force generated by the operation.

  If the electrical connector disclosed in Patent Document 1 is used, the wiring board can be connected to the circuit board without applying a load by rotating the shell away from the housing to release the locking member and the wiring board. Can be easily pulled out from.

  However, in this electrical connector, a space for rotating the housing with respect to the shell is required, and thus there is a possibility that advantages (such as space saving) due to the low profile of the electrical connector may be impaired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electrical connector that can be easily pulled out while securely holding a wiring board without impairing the advantages of low profile. .

In order to achieve the above object, an electrical connector according to the present invention comprises:
An electrical connector for electrically connecting a flat wiring board to a circuit board,
A housing into which an end of the wiring board is inserted from an insertion port;
A pair of extending members extending from the back side of the housing toward the insertion port, wherein locking claws for engaging with engaging portions provided at both edges in the width direction of the wiring board are the extending members. A locking member provided at each tip of
A first position where each of the extending members is suppressed and the locking claw is engaged with the engaging portion, and the suppression of each of the extending members is released, and the engagement between the locking claw and the engaging portion is released. A slide member slidably mounted relative to the housing between a second position and

  According to the present invention, the lock member that is locked to the wiring board is suppressed by the slide member mounted on the housing. When pulling out the lock member, the slide member is slid to unlock the lock substrate from the wiring board. Since the slide by the slide member does not require as much space as rotating relative to the housing, the wiring board can be securely held and easily pulled out without impairing the advantages of low profile.

Embodiment 1 FIG.
Hereinafter, an electrical connector 1A according to Embodiment 1 of the present invention will be described with reference to the drawings. In each figure, an orthogonal coordinate system in which the longitudinal direction of the electrical connector 1A is the x-axis direction, the short direction is the y-axis direction, and the thickness direction is the z-axis direction is set and referred to as appropriate. The arrow direction of each axis is indicated by + (plus), and the opposite direction is indicated by-(minus).

  As shown in FIG. 1, the electrical connector 1 </ b> A is mounted on the + z side plane of the circuit board 2. The circuit board 2 is a main circuit board on which, for example, a semiconductor chip for controlling an electric device or an electronic device is mounted. The electrical connector 1 </ b> A electrically and physically connects the FPC (flexible printed circuit board) 3 shown in FIGS. 2A and 2B to the circuit board 2. FIG. 2A is a perspective view of the end of the FPC 3 on the + y side as viewed obliquely from the + z side, and FIG. FIG.

  As shown in FIGS. 2A and 2B, the FPC 3 is a flexible flat wiring board. As shown in FIG. 2B, a plurality of contacts 4 are arranged in parallel at equal intervals in the x-axis direction on the −z side of the end of the FPC 3 on the + y side. Notches 5 are provided at both ends in the width direction (x-axis direction) near the + y side end of the FPC 3.

  “Electrically connected” described above means that each contact 4 of the FPC 3 is electrically connected to a circuit (not shown) formed on the circuit board 2. Further, “physically connected” means that the end of the FPC 3 is fixed to the circuit board 2.

  The electrical connector 1A includes a housing 10, a shell 11F, and a slide member 12. A connector main body 40 is formed by the housing 10 and the shell 11F. The + y side end of the FPC 3 shown in FIGS. 2 (A) and 2 (B) is inserted into the housing 10. The shell 11F is formed by bending a single plate-like member into a concave shape, and the housing 10 is incorporated in the concave portion. The lock member 11 is formed integrally with the shell 11F. The slide member 12 is incorporated on the shell 11F.

  The housing 10 is made of a polymer resin that is an insulating material. As shown in FIGS. 1, 3A, 3B, and 3C, the housing 10 has a rectangular parallelepiped shape that is elongated in the x-axis direction as a whole. The side surface in the x-axis direction forms the left side surface (-x surface) and the right side surface (+ x surface), and the side surface in the short direction (y-axis direction) forms the front surface (-y surface) and the back surface (+ y surface). The surface in the + z direction forms the upper surface and the surface in the -z direction forms the bottom surface.

  As shown in FIGS. 1 and 3C, an insertion port 20 is provided on the front surface (-y plane). The insertion port 20 is a rectangular opening having a size capable of sufficiently inserting the FPC 3 and having the x-axis direction as a longitudinal direction. Inside the housing 10, an accommodation space is provided in which the + y side end of the FPC 3 is inserted through the insertion port 20 and accommodated. This space has a rectangular parallelepiped shape. In this space, the + y side end of the FPC 3 is inserted from the insertion port 20 in the + y direction.

  In the accommodation space into which the FPC 3 is inserted, a plurality of contacts 21 are provided side by side at equal intervals in the longitudinal (x-axis) direction. The contact 21 is made of a conductive material such as metal. The contact 21 contacts the contact 4 of the FPC 3. The arrangement interval of the contacts 21 is the same as the arrangement interval of the contacts 4 of the FPC 3. When the FPC 3 is inserted into the housing 10, each contact 21 comes into contact with any one of the contacts 4. As shown in FIG. 3A, the contact 21 extends to the + y side and is also connected to a circuit (not shown) of the circuit board 2 on which the electrical connector 1A is mounted.

  Two openings extending in the y-axis direction are provided on the upper surface of the housing 10. This opening is provided corresponding to the position of the notch 5 of the FPC 3 inserted into the housing 10.

  As shown in FIGS. 1, 3 (A), 3 (B), and 3 (C), the shell 11 F covers a part of the upper surface of the housing 10 on the + y side, the left side surface, and the right side surface. It is attached to the housing 10. The pair of lock members 11 are provided along two openings provided in the housing 10. As shown in FIG. 4, the lock member 11 is a pair of extending members extending from the back side (+ y side) of the housing 10 toward the insertion port 20 (−y direction). The lock member 11 is a fixed end with the + y end fixed to the shell 11F, and the −y end is a free end.

  Each lock member 11 is a flexible leaf spring member. The lock member 11 can be bent in the direction of arrow B (around the x axis). The -y end of the lock member 11 can enter the accommodation space in the housing 10 through an opening provided on the upper surface of the housing 10.

  A lock claw 22 is provided at the −y end of each lock member 11. The lock claw 22 is large enough to fit into the notch 5 of the FPC 3. When the FPC 3 is inserted into the housing 10 combined with the shell 11F, that is, the connector main body 40, the lock claw 22 engages with the notches 5 provided on both edges in the width direction (x-axis direction) of the FPC 3. In a state where the lock members 11 and the cutouts 5 of the FPC 3 are locked, the FPC 3 enters into the innermost part (+ y side) of the connector main body 40. At this time, the contact 4 of the FPC 3 comes into contact with the contact 21 of the connector main body 40. The clearance between the lock claw 22 and the bottom surface in the space of the connector body 40 (the inner bottom surface on the −z side) when the lock member 11 is bent to the maximum is equal to or greater than the thickness of the FPC 3 (the width in the z-axis direction). ing.

  Each lock member 11 is urged in a direction (in the direction of arrow B) to release the locking claw 22 and the notch 5 from being locked. When each lock member 11 is not restrained to the −z side, the lock claw 22 is retracted from the accommodation space.

  An inclined surface 23 is provided at the tip of the lock claw 22 so that the shape of the claw tapers toward the tip on the -y side. As shown in FIG. 5A, the inclined surface 23 is provided such that when the FPC 3 is inserted into the housing 10, the + z side edge at the end of the FPC 3 abuts. When the FPC 3 further enters the inside of the housing 10, the inclined surface 23 slides with the abutted FPC 3 as shown in FIG. When the inclined surface 23 slides on the FPC 3, the lock member 11 is deformed by the reaction from the FPC 3, and is bent to the + z side (around the x axis). Accordingly, as shown in FIG. 5C, the FPC 3 comes under the lock claw 22.

  The state in which the FPC 3 enters under the lock claw 22 is shown in FIGS. Thereafter, when the notch 5 of the FPC 3 reaches the lock claw 22, the lock claw 22 enters the notch 5, and both are locked. This state is shown in FIGS. In the state where the lock claw 22 is locked to the notch 5, that is, the state shown in FIGS. 9 to 12, the FPC 3 is inserted to the innermost part of the housing 10 and is firmly fixed.

  As described above, the inclined surface 23 of the lock claw 22 is provided to avoid interference between the FPC 3 and the lock claw 22 until the FPC 3 enters the back side of the housing 10 and the lock claw 22 engages with the notch 5. ing. The inclination angle of the inclined surface 23 is preferably within 45 degrees with respect to the x-axis. Further, it is desirable that the inclined surface 23 has a surface roughness that allows the FPC 3 to slide smoothly.

  The slide member 12 is provided outside the connector body 40 so as to be slidable with respect to the shell 11F. The slide member 12 is made of metal. The slide member 12 slides in the y-axis direction with respect to the shell 11F.

  The position of the slide member 12 with respect to the shell 11F shown in FIGS. 1, 3A to 3C, 4, 6, 8 and 9 to 11 is defined as a position P1 (first position). And On the other hand, the position of the slide member 12 with respect to the shell 11F shown in FIGS. 13 to 15 is defined as a position P2 (second position).

  The slide member 12 is attached to the shell 11F so as to be slidable between the position P1 and the position P2. The position P1 is a position where each lock member 11 is suppressed and the lock claw 22 is engaged with the notch 5. The position P2 is a position at which the locking of each lock member 11 is released and the lock claw 22 and the notch 5 of the FPC 3 are unlocked.

  The slide member 12 is provided with a leaf spring member 24 that holds the lock members 11 when the slide member 12 is at the position P1. By this leaf spring member 24, the slide member 12 can hold down each lock member 11 firmly. Thereby, it becomes difficult for the FPC 3 to come out of the connector main body 40.

  When the slide member 12 is at the position P2, as shown in FIGS. 13, 14A to 14C, and 15, the lock claw 22 is retracted to the outside of the accommodation space. Thereby, the FPC 3 can be extracted from the housing 10.

  A rectangular hole 25 whose longitudinal direction is the y-axis direction is provided on the side surface of the slide member 12 in the x-axis direction. A rectangular protrusion 26 inserted into the rectangular hole 25 is provided on the side surface in the x-axis direction of the shell 11F. When the slide member 12 is at the position P1, the protruding portion 26 is located on the + y side of the rectangular hole 25. On the other hand, when the slide member 12 is at the position P2, the protruding portion 26 is located on the −y side of the rectangular hole 25.

  Based on the position of the protruding portion 26, it can be determined whether the slide member 12 is at the position P1 or the position P2. In the present embodiment, the rectangular hole 25 and the protruding portion 26 correspond to an “identification portion” that can visually confirm whether the slide member 12 is at the position P1 or the position P2.

  A hole-like engagement recess 27 is provided on the side surface of the slide member 12 in the x-axis direction, and a protrusion-like engagement projection 28 is provided on the side surface of the shell 11F where the lock member 11 is provided. The slide member 12 can be held at the position P1 by the engagement recess 27 and the engagement projection 28 engaging with each other. When the slide member 12 is located at the position P2, the engagement concave portion 27 and the engagement convex portion 28 are displaced. Therefore, the engaging concave portion 27 and the engaging convex portion 28 can be used as the “identifying portion”. Note that an engagement recess may be formed in the shell 11F, and an engagement protrusion may be formed in the slide member 12.

  Next, the operation when the FPC 3 is inserted and removed from the electrical connector 1A will be described.

  First, when the FPC 3 is not inserted, the electrical connector 1A is in the state shown in FIGS. In this state, the slide member 12 is located at the position P1. The sliding member 12 is positioned at the position P1 because the protruding portion 26 of the shell 11F is on the + y side of the sliding member 12 or the engaging concave portion 27 and the engaging convex portion 28 are engaged. This can be confirmed visually.

  In this state, the FPC 3 is inserted into the housing 10 through the insertion port 20. As shown in FIGS. 5A to 5C, the FPC 3 slides in contact with the inclined surface 23 of the lock claw 22. Since the lock member 11 is held by the leaf spring member 24 from the upper surface (+ z side), the lock member 11 is bent to the + z side, and the FPC 3 enters under the lock claw 22. The state in which the FPC 3 has entered under the lock claw 22 is shown in FIGS. 6, 7 </ b> A to 7 </ b> C, and FIG. 8.

  When the notch 5 of the FPC 3 reaches the position of the lock claw 22, the lock member 11 is lowered by the elastic force of the lock member 11 itself, and FIG. 9, FIG. 10 (A) to FIG. 10 (C), FIG. It will be in the state shown in. That is, the lock member 11 is engaged with the notch 5 of the FPC 3.

  Next, a case where the FPC 3 is extracted will be described. In this case, as shown in FIGS. 13, 14A to 14C, and 15, the slide member 12 is slid to the position P2. When the protruding portion 26 of the shell 11F is on the -y side, it can be visually confirmed that the slide member 12 is positioned at the position P2. When the slide member 12 slides to the position P2, the lock member 11 is released from the -z side. Then, each lock member 11 jumps up to the + z side, and the lock between each lock member 11 and the FPC 3 is released. In this state, the FPC 3 can be easily extracted from the housing 10.

  Next, a manufacturing process of the electrical connector 1A according to the present embodiment will be described. First, the housing 10 is formed by injection molding, and the contact 21 is mounted inside. On the other hand, the metal shell 11F, the lock member 11, and the slide member 12 are formed separately. Thereafter, the housing 10 is fitted into the shell 11F, and the protruding portion 26 of the shell 11F is fitted into the rectangular hole 25 of the slide member 12, whereby the electrical connector 1A is formed.

  As described in detail above, in the present embodiment, the lock member 11 that is engaged with the FPC 3 is suppressed by the slide member 12 that is attached to the shell 11F. When the lock member 11 is pulled out, the slide member 12 is slid to unlock the lock member 11 from the FPC 3. Since the slide by the slide member 12 does not require a space for rotating with respect to the connector main body 40, the FPC 3 can be securely held and easily pulled out without impairing the advantage of the low profile.

  By positioning the slide member 12 at the position P1, the lock member 11 can be reliably locked to the FPC 3. By positioning the slide member 12 at the position P2, it is possible to prevent the FPC 3 from being damaged when the lock member 11 is removed and the FPC 3 is removed.

  According to the present embodiment, the leaf spring member 24 that suppresses each lock member 11 when the slide member 12 is at the position P1 is provided. In this way, the locking force of each lock member 11 can be increased and the FPC 3 can be firmly fixed.

  According to the present embodiment, each lock member 11 is biased in a direction (+ z direction) in which the locking claw 22 and the notch 5 of the FPC 3 are unlocked. Thereby, if the slide member 12 is slid to the position P2, the lock member 11 can be automatically retracted from the housing space of the housing 10, and the FPC 3 can be easily extracted from the connector main body 40. As a result, the FPC 3 can be safely extracted from the connector main body 40 without breakage, and the operation for releasing the locking claw 22 and the notch 5 is not required, so that the number of extraction operations can be reduced. it can.

  According to the present embodiment, each lock member 11 has flexibility. When the FPC 3 is inserted into the connector main body 40, the slide member 12 is at the position P1. The FPC 3 is inserted into the connector main body 40 when the lock member 11 is curved. Therefore, the FPC 3 can be fixed to the connector main body 40 by one operation (so-called one-touch operation). Thereby, the operation of manually locking the lock member 11 to the notch 5 of the FPC 3 is not required, so that the operation of inserting the FPC 3 into the connector main body 40 can be simplified.

  According to the present embodiment, when the slide member 12 is at the position P <b> 2, the lock claw 22 is retracted from the housing space of the connector main body 40. In this way, it is possible to prevent the lock claw 22 from being caught by the FPC 3 when the FPC 3 is extracted from the connector main body 40.

  Further, according to the position of the protruding portion 26 in the rectangular hole 25 or the engaged state of the engaging concave portion 27 and the engaging convex portion 28, the fitted state / unlocked state can be seen at a glance from the upper surface of the connector body 40. It has become. For this reason, when the FPC 3 is inserted into the connector main body 40, it is easy to confirm whether or not the slide member 12 is at the position P1. Further, when the FPC 3 is removed from the connector main body 40, it is easy to confirm whether or not the slide member 12 is at the position P2. For this reason, the possibility that the position of the slide member 12 is mistaken when the FPC 3 is inserted or removed can be reduced, and the productivity (yield) of the electric device or the electronic device can be significantly improved.
