Description

  The present invention relates to a clip-type connector that obtains electrical connection with the flexible printed wiring board by sandwiching the flexible printed wiring board.

  2. Description of the Related Art In recent years, flexible printed wiring boards have come to be used when electronic circuits are connected to each other internally because of advantages such as easy assembly and miniaturization. In such an electronic device, before the circuits are actually connected to each other, the flexible printed wiring board and each circuit are inspected in advance. The inspection is performed, for example, by connecting a circuit and an inspection device via a flexible printed wiring board and transmitting various signals from the inspection device.

  The flexible printed wiring board is usually connected to each circuit, an inspection device, and the like via a male / female fitting connector composed of a plug and a socket. The mating connector has advantages that stable coupling can be obtained and there is less fear of dropping off after connection, but there are disadvantages such as that it takes time to attach and detach, and durability is low. Since the inspection as described above is performed in units of several hundred times a day, using a fitting-type connector to connect to the inspection device takes time for attachment and detachment, and the inspection time is unnecessarily long. Such a problem occurs that the connector on the inspection apparatus side where the above is repeated is damaged immediately.

In order to solve the above-mentioned problem, a clip-type connector is obtained in which a flexible printed wiring board is sandwiched and fixed, and the probe is directly brought into contact with a contact terminal provided on the flexible printed wiring board at this time, For example, it is known from Patent Document 1. In the clip-type connector, it is only necessary to sandwich the flexible printed wiring board, so that it can be easily attached and detached. Further, since the structure is simple, the durability is higher than that of the fitting type connector.
Japanese Utility Model Publication No. 6-2259

  However, since the clip-type connector described in Patent Document 1 simply sandwiches the flexible printed wiring board, if an external force is applied to the flexible printed wiring board or the like after connection, the contact terminal and the probe are displaced and become conductive. May not be obtained. Such a contact failure directly leads to problems such as the need for re-inspection and the determination of a normal circuit as a defective product.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a clip-type connector that can prevent the sandwiched flexible printed wiring board from being displaced even when an external force is applied.

  In order to achieve the above object, a clip-type connector of the present invention includes a base that supports a flexible printed circuit board, and is swingably attached to the base, and sandwiches the flexible printed circuit board together with the base. An arm that moves between a closed position that provides electrical connection with the flexible printed wiring board and an open position that allows the flexible printed wiring board to be attached and detached; and the flexible print when the arm moves to the closed position. An engagement member is provided that engages with a notch formed in the wiring board and releases the engagement with the notch when the arm moves to the open position.

  The base is formed with a recess into which the distal end portion of the flexible printed circuit board enters, and the engaging member is attached to the base so as to be slidable in the width direction of the flexible printed circuit board. Between an engagement position that enters the recess and engages with the notch formed at a side edge of the flexible printed wiring board, and a retract position that retracts from the recess and releases the engagement with the notch It is preferable to move by.

  The base includes an elastic member for an engagement member that urges the engagement member to the retracted position, and the engagement member comes into contact with the arm that has moved to the closed position. It is preferable to move from the retracted position to the engaging position against the biasing of the engaging member elastic body.

  Further, the engaging member is formed on the arm in a substantially cylindrical shape or a substantially prismatic shape, and is configured to engage with the notch so as to enter from above when the arm moves to the closed position. May be.

  The base includes a recess into which a tip portion of the flexible printed circuit board enters, the engagement member formed in a substantially columnar shape or a substantially prismatic shape so as to protrude from the bottom surface of the recess, and the engagement member A movable member attached to the concave portion so as to be movable up and down between a first position for hiding the engaging member and a second position for exposing the engaging member; and a movable member for biasing the movable member to the first position And the movable member moves from the first position to the second position against the bias of the movable member elastic body by contacting the arm moved to the closed position. The engaging member may be configured to engage with the notch so as to enter from below when the movable member moves to the second position and is exposed.

  At this time, a gate for guiding the tip portion of the flexible printed circuit board into the recess may be provided on the movable member.

  Furthermore, it is preferable to provide a detecting means for detecting that the engaging member and the notch are engaged. At this time, the contact member is formed of a conductive material, and the contact means detects that the engagement member and the notch are engaged by obtaining electrical continuity with the engagement member. Is preferable.

  Moreover, it is preferable that the engaging member and the notch are provided in a pair of left and right.

  According to the clip-type connector of the present invention, since the engaging member that engages with the notch formed in the flexible printed wiring board when the arm moves to the closed position is provided, even when an external force or the like is applied, It is possible to prevent the flexible printed wiring board from being displaced. Further, since the engaging member releases the engagement with the notch when the arm moves to the open position, the engaging member does not get in the way when the flexible printed circuit board is attached or detached.

  As shown in FIG. 1, the clip-type connector 2 includes a base 10 that supports the flexible printed wiring board 4 and an arm 12 that is swingably attached to the base 10. The clip-type connector 2 obtains electrical connection with the flexible printed wiring board 4 by sandwiching and fixing the flexible printed wiring board 4 between the base 10 and the arm 12.

  The arm 12 is formed by a flat plate portion 20 and side plate portions 22 provided on both side ends of the flat plate portion 20 so as to protrude toward the base 10 so that the cross section is substantially U-shaped. Yes. Each side plate portion 22 is formed with a circular through hole 24 for attaching the arm 12 to the base 10. Further, each side plate portion 22 is obliquely cut behind the through hole 24 in order to allow swinging during the opening / closing operation after being attached to the base 10.

  The base 10 is provided with a frame 30 protruding in a substantially U shape. The lateral width of the outer side of the frame 30 is matched to the inner spacing of each side plate portion 22 of the arm 12. The lateral width inside the frame 30 is matched to the lateral width of the flexible printed wiring board 4. That is, the frame 30 forms a recess 32 into which the leading end portion of the flexible printed wiring board 4 enters. The recess 32 regulates the position in the width direction and the depth direction of the flexible printed wiring board 4 that has entered, and positions the flexible printed wiring board 4 at a predetermined position.

  The frame 30 is formed with a circular through hole 34 penetrating in the width direction. The arm 12 is attached to the base 10 by aligning the through hole 24 of each side plate portion 22 with the through hole 34 of the frame 30 and inserting the cylindrical shaft rod 14 into each of the through holes 24 and 34. As a result, the arm 12 swings around the shaft rod 14 between a closed position shown in FIG. 2A and an open position shown in FIG. 2B. The shaft rod 14 is prevented from falling off by, for example, a cap that closes each through hole 24 from the outside.

  The arm 12 in the closed position clamps and fixes the flexible printed wiring board 4 that has entered the recess 32 together with the base 10. On the other hand, the arm 12 in the open position releases the pinching and fixing, and enables the flexible printed wiring board 4 to be attached to and detached from the clip connector 2. Two coil springs 16 are sandwiched between the base 10 and the arm 12. Each coil spring 16 biases the arm 12 toward the closed position.

  The arm 12 is provided with a plurality of probes 26 in which a conductive material such as metal is formed in a pin shape, arranged in the width direction. The number of each probe 26 is adjusted to a plurality of connection terminals 6 formed side by side at the tip of the flexible printed wiring board 4. Each probe 26 is arranged so as to come into contact with each connection terminal 6 when the arm 12 moves to the closed position with the flexible printed wiring board 4 accurately positioned in the recess 32.

  Further, the arm 12 is provided with a spring that biases each probe 26 so as to protrude, and each probe 26 is slightly pushed into the arm 12 when contacting each contact terminal 6. Thus, the contact state with each connection terminal 6 can be stabilized by making each probe 26 contact elastically. Further, a protruding portion 28 protruding toward the base 10 is formed on the inner surface of the arm 12. The protrusion 28 presses the flexible printed wiring board 4 together with each probe 26 when each probe 26 comes into contact with each contact terminal 6, and stabilizes the clamping and fixing of the flexible printed wiring board.

  As a result, the clip-type connector 2 holds the flexible printed wiring board 4 by holding the arm 12 in the closed position, and obtains conduction with the flexible printed wiring board 4 via the probes 26. Each probe 26 is connected to an inspection device for inspecting the flexible printed wiring board 4 and a circuit connected to the flexible printed wiring board 4 via a board or wiring attached to the arm 12.

  Cutouts 8 are formed at both side ends near the front end of the flexible printed wiring board 4. The frame 30 of the base 10 is provided with a pair of engaging members 36 that are engaged with the notches 8 to prevent the flexible printed wiring board 4 from being displaced. Each engaging member 36 is positioned so as to face each notch 8 when the flexible printed wiring board 4 is accurately positioned in the recess 32.

  As shown in FIG. 3, the frame 30 is formed with a through hole corresponding to the shape of each engaging member 36. Each engaging member 36 is assembled to the frame 30 so as to be slidable in the width direction by entering each of the through holes. Each engaging member 36 is formed to be slightly longer than the thickness of the frame 30, and one end protrudes outside the frame 30 or inside the frame 30 (in the recess 32).

  The base 10 is formed with a groove 40 for allowing the sliding movement of each engaging member 36. Each groove 40 is provided with a coil spring (engagement member elastic body) 42 that biases each engagement member 36 outward. Each engagement member 36 is formed in a substantially L shape so as not to protrude outward from a predetermined position by engagement with a step formed inside the frame 30. Thereby, as shown in FIG. 3, each engagement member 36 is held in a state in which one end protrudes outside the frame 30 when the arm 12 is in the open position.

  An inclined surface 36 a is formed at the end of each engaging member 36 that protrudes outside the frame 30. When the arm 12 moves to the closed position, the inclined surface 36 a and the side plate portion 22 of the arm 12 come into contact with each other, and each engaging member 36 moves toward the inside of the frame 30 against the coil spring 42. As a result, each engaging member 36 enters the recess 32 and engages with the notch 8 of the flexible printed wiring board 4 as shown in FIG. Thus, each engagement member 36 moves to an engagement position (see FIG. 4) that engages with each notch 8 when the arm 12 is in the closed position, and the recess 32 when the arm 12 is in the open position. Is moved to a retracted position (see FIG. 3) where the engagement with each notch 8 is released.

  Next, the operation of the clip-type connector 2 having the above configuration will be described. The clip-type connector 2 is held in a state where the arm 12 is in the closed position by the bias of the coil spring 16. When connecting the clip-type connector 2 and the flexible printed circuit board 4, the rear ends of the base 10 and the arm 12 are gripped, and the arm 12 is moved to the open position against the bias of the coil spring 16. . When the arm 12 moves to the open position, the contact between each engagement member 36 and each side plate portion 22 is released, and each engagement member 36 at the engagement position moves to the retracted position.

  After the arm 12 is set to the open position, the flexible printed wiring board 4 is positioned by inserting the distal end portion of the flexible printed wiring board 4 into the concave portion 32 and abutting the distal end 4 a against the inner side surface 32 a of the concave portion 32. At this time, since each engagement member 36 has moved to the retracted position, each engagement member 36 does not get in the way during positioning. After positioning the flexible printed wiring board 4, the arm 12 is returned to the closed position.

  When the arm 12 is moved to the closed position, the flexible printed wiring board 4 is sandwiched and fixed by the base 10 and the arm 12, and the connection terminals 6 and the probes 26 come into contact with each other. The substrate 4 is electrically connected. Further, when the arm 12 moves to the closed position, each engagement member 36 moves to the engagement position by contact with each side plate portion 22 and engages with each notch 8 of the flexible printed wiring board 4. By this engagement, displacement of the flexible printed wiring board 4 with respect to the clip-type connector 2 is prevented. Thus, according to this example, it is possible to prevent the sandwiched flexible printed wiring board 4 from being displaced without impairing the ease of attachment / detachment.
