When the lower ends of the two clamping arms continue to move toward the direction close to the connector, the reinforcement plate and the gold fingers are inserted into the connector. After that, the operator squeezes the upper ends of the two clamping arms again to rotate the lower ends of the two clamping arms in the opposite direction, and then lifts the flexible circuit board insertion jig to complete the insertion operation and insert the reinforcement plate and the gold fingers into the connector.

[0017] The flexible circuit board insertion jig of the utility model can form two spaced clamping positions at the position of the pressing part and at the position between the clamping part of the first floating clamping structure and the clamping part of the second floating clamping structure, which can prevent the reinforcing plate and the gold finger from bending during the insertion operation, thereby damaging the flexible circuit board. At the same time, since the clamping part of the first floating clamping structure and the clamping part of the second floating clamping structure are clamped at the two side surfaces of the reinforcing plate and the gold finger, and can slide relative to the reinforcing plate and the gold finger, they can play a guiding role when the reinforcing plate and the gold finger are inserted into the interior of the connector, so that the reinforcing plate and the gold finger can be smoothly inserted into the interior of the connector, and the insertion operation is very convenient, which solves the problems of inconvenience in manually inserting the flexible circuit board and easy damage to the flexible circuit board.

[0028] like Figures 1 to 6 As shown, the flexible circuit board insertion jig of the utility model comprises two clamping arms connected in an articulated manner, an elastic torsion structure for driving the lower ends of the two clamping arms to rotate toward each other, and a floating fixing structure arranged at the lower ends of the two clamping arms. A clamping slot 11 for placing a reinforcement plate is provided at the lower end of one clamping arm, and a pressing portion 12 is provided at the lower end of the other clamping arm corresponding to the clamping slot 11, which is used to press the reinforcement plate 40 (the gold finger of the flexible circuit board 30 is attached to the reinforcement plate 40); the floating fixing structure comprises two clamping arms respectively arranged at the lower ends of the two clamping arms. The first floating clamping structure 20a and the second floating clamping structure 20b respectively include a slide 21 slidably installed on the clamping arm along the length direction of the clamping arm, a clamping portion 22 fixed to the portion of the slide 21 located outside the lower end of the clamping arm, and an elastic retractable member 23 for pushing the clamping portion 22 to slide in a direction away from the lower end of the clamping arm. The clamping portion 22 of the first floating clamping structure 20a is arranged adjacent to the clamping portion 22 of the second floating clamping structure 20b.

[0029] For ease of understanding, the following description is given in conjunction with the use of the flexible circuit board insertion jig:

[0030] The operator holds the flexible circuit board insertion fixture, squeezes the upper ends of the two clamping arms to make the lower ends of the two clamping arms rotate in the divergent direction, and synchronously drives the first floating clamping structure 20a and the second floating clamping structure 20b to rotate in the divergent direction, puts the reinforcement plate 40 and the gold finger into the card slot 11, loosens the upper ends of the two clamping arms, and under the elastic force of the elastic torsion structure, the lower ends of the two clamping arms rotate toward each other, and the first floating clamping structure 20a and the second floating clamping structure 20b follow the synchronous rotation until the clamping part 12 is pressed on the reinforcement plate 40 and the gold finger at the card slot 11. At the same time, the clamping part 22 of the first floating clamping structure 20a and the clamping part 22 of the second floating clamping structure 20b are clamped on the reinforcement plate 40 and the gold finger located outside the card slot 11, as shown in FIG. Figure 4 and Figure 5As shown; when the operator holds the flexible circuit board insertion jig and inserts the reinforcing plate 40 and the gold finger into the connector 50, the clamping portion 22 of the first floating clamping structure 20a and the clamping portion 22 of the second floating clamping structure 20b touch the connector 50. Since the slide seat 21 of the first floating clamping structure 20a and the slide seat 21 of the second floating clamping structure 20b are respectively slidably connected to the clamping arms, the lower ends of the two clamping arms will continue to move toward the direction close to the connector 50, and the first floating clamping structure 20a Relative sliding occurs between the clamping portion 22 of the second floating clamping structure 20b and the reinforcing plate 40 and the gold finger. When the lower ends of the two clamping arms continue to move toward the connector 50, the reinforcing plate 40 and the gold finger are inserted into the connector 50. Then, the operator squeezes the upper ends of the two clamping arms again to rotate the lower ends of the two clamping arms in the opposite direction, and then lifts the flexible circuit board insertion jig to complete the insertion operation, and inserts the reinforcing plate 40 and the gold finger into the connector 50.

[0031] Since the flexible circuit board insertion jig can form two spaced clamping positions at the position of the pressing portion 12 and between the clamping portion 22 of the first floating clamping structure 20a and the clamping portion 22 of the second floating clamping structure 20b, it is possible to prevent the reinforcing plate 40 and the gold finger from bending during the insertion operation, thereby damaging the flexible circuit board 30. At the same time, since the clamping portion 22 of the first floating clamping structure 20a and the clamping portion 22 of the second floating clamping structure 20b are clamped at the two side surfaces of the reinforcing plate 40 and the gold finger, and can slide relative to the reinforcing plate 40 and the gold finger, they can play a guiding role when the reinforcing plate 40 and the gold finger are inserted into the connector 50, so that the reinforcing plate 40 and the gold finger can be smoothly inserted into the connector 50, and the insertion operation is very convenient, which solves the problem of inconvenience in manually inserting the flexible circuit board and easy damage to the flexible circuit board.

[0032] In the present invention, the two clamping arms are respectively a first clamping arm 10a and a second clamping arm 10b, wherein the length of the first clamping arm 10a is greater than the length of the second clamping arm 10b, and the lower end of the first clamping arm 10a is flush with the lower end of the second clamping arm 10b. During the insertion operation, the operator holds the upper end of the first clamping arm 10a to facilitate the vertical insertion of the reinforcing plate 40 and the gold finger into the connector 50, and at the same time, it can avoid the first clamping arm 10a and the second clamping arm 10b from rotating in opposite directions due to misoperation.

[0033] Specifically, the card slot 11 is arranged at the lower end of the first clamping arm 10a, and a notch portion 111 is provided on the slot wall of the card slot 11 close to the second clamping arm 10b, so that the clamping portion 12 can be pressed on the reinforcing plate 40 and the gold finger at the corresponding notch portion 111.

[0034] Furthermore, the clamping surface of the clamping portion 22 of the first floating clamping structure 20a close to the second floating clamping structure 20b is flush with the side of the slot wall of the card slot 11 away from the second clamping arm 10b. When the pressing portion 12 is pressed on the reinforcing plate 40 and the gold finger, and the clamping portion 22 of the first floating clamping structure 20a and the clamping portion 22 of the second floating clamping structure 20b are clamped on the reinforcing plate 40 and the gold finger outside the card slot 11, the straight state of the reinforcing plate 40 and the gold finger can be maintained, which is not only convenient for insertion, but also can avoid bending of the reinforcing plate 40 and the gold finger. Usually, the clamping portion 22 is set as a long clamping block and connected to the slide seat 21 as an integrated structure.

[0035] In some other embodiments, a clearance hole for the clamping portion 12 to be inserted into the slot 11 may be provided on the slot wall on the side of the slot 11 close to the second clamping arm 10 b , and the clamping portion 12 passes through the clearance hole to clamp the reinforcing plate 40 and the gold finger.

[0036] In the present utility model, in order to facilitate the operator to hold the flexible circuit board insertion jig, the first clamping arm 10a is set as the first long strip, and the second clamping arm 10b is set as the second long strip, and it is convenient for the slide 21 of the first floating clamping structure 20a to slide along the first long strip, and the slide 21 of the second floating clamping structure 20b to slide along the second long strip. Usually, first hinged ears are respectively provided at the long sides of the opposite sides of the first long strip, and correspondingly, second hinged ears are respectively provided at the long sides of the opposite sides of the second long strip, and the two second hinged ears are respectively provided between the two first hinged ears, and a rotating shaft is connected between the two first hinged ears and the two second hinged ears; the elastic torsion structure is a torsion spring, and the main spring body of the torsion spring is sleeved on the rotating shaft between the two second hinged ears, and the two torsion spring arms of the torsion spring are respectively against the plate surface of the first long strip and the second long strip.

[0037] Specifically, the pressing portion 12 is configured as a long pressing block extending along the width direction of the second long plate, which can increase the contact area, improve the pressing effect, and avoid damaging the reinforcing plate 40 and the gold finger. Usually, the long pressing block is connected to the second long plate as an integrated structure.

[0038] In the utility model, a mounting block 13 is provided on the clamping arm, and a mounting through hole is provided on the mounting block 13 along the length direction of the clamping arm. A mounting shaft 25 passing through the mounting through hole is fixed on the slide seat 21, and a limiting structure is provided at the end of the mounting shaft 25 passing through the mounting through hole. The sliding connection is achieved by the cooperation between the mounting shaft 25 and the mounting through hole on the mounting block 13. Usually, the limiting structure is a limiting rod passing through the mounting shaft 25, and it can also be an end cap fixed at the end of the mounting shaft 25, such as a nut, a retaining ring, etc.; the elastic telescopic member 23 is sleeved on the mounting shaft 25 between the mounting block 13 and the slide seat 21. Usually, the elastic telescopic member 23 is a telescopic spring, and it can also be an elastic sleeve.

[0039] In order to ensure that the slide seat 21 can always fit on the clamping arm when sliding, the thickness of the mounting block 13 is increased to increase the length of the mounting through hole. Of course, the mounting shaft 25 can also be set as a quadrangular prism, which can also play a guiding role while achieving a sliding connection.

[0040] Specifically, a slideway is provided on the slide 21 along the length direction of the clamping arm, and a stopper 14 is provided on the clamping arm along the width direction of the clamping arm. The width of the stopper 14 matches the width of the slideway and is used for limiting the position to prevent the slide 21 from deflecting when sliding. Usually, the slideway is an elongated through hole 24 provided on the slide 21.

[0041] The above descriptions are only some embodiments of the present invention and are not intended to limit the present invention.
