[0002] With the development of electronic technology, flexible conductive parts such as flexible circuit boards and conductive films have been widely used in the structure and production process of electronic products. Flexible conductive parts are usually connected electrically by plugging the plug-in end with gold fingers into the connector of the substrate. At present, the operation method in the factory is mainly to manually use metal tweezers or pinch the plug-in end of the flexible conductive part with bare hands to insert it into the connector of the substrate.
[0003] Although the above operation method can realize the plugging of the plug-in end of the flexible conductive member with the connector, it has the following disadvantages:
[0004] 1. When using metal tweezers to pick up flexible conductive parts for plugging, it is not only very easy to scratch the flexible conductive parts, but also because there is no positioning between the front end of the metal tweezers and the flexible conductive parts, when the clamping is deflected, it is very easy to cause the gold fingers of the plug-in end of the flexible conductive parts to be broken, thereby causing poor function of the flexible conductive parts;
[0005] Second, when manually picking up flexible conductive parts for plugging, high requirements are placed on the position of the connector on the substrate and the working space. The structure of most electronic products cannot meet this design requirement. Utility Model Content
[0006] In view of the above defects in the prior art, the utility model provides a clamping jig, which effectively solves the problems of scratches, breaks and the like occurring during the plugging process of the flexible conductive parts, and ensures the yield rate of the flexible conductive parts.

[0009] Preferably, the height of the clamping limit platform is not less than the thickness of the reinforcement plate.
[0010] Preferably, the height of the clamping limit platform is 0.02 mm greater than the thickness of the reinforcement plate.
[0011] Preferably, the anti-scratch clamping block is made of plastic, and the corners of the anti-scratch clamping block are all rounded.
[0012] Preferably, the upper clamping arm includes an upper connecting section and an upper clamping section arranged at a first angle, the lower clamping arm includes a lower connecting section and a lower clamping section arranged at a second angle, the upper connecting section is hinged to the middle part of the lower connecting section, the anti-scratch clamping block is arranged at the clamping end of the upper clamping section, and the clamping limit platform is protrudingly arranged at the clamping end of the lower clamping section.
[0013] Preferably, a clamping guide structure is provided between the upper connecting section and the lower connecting section.
[0014] Preferably, the clamping guide structure includes two guide columns arranged on the lower connecting section, the two guide columns are arranged on opposite sides of the lower connecting section, and the two guide columns extend toward the direction where the upper connecting section is located, and the upper connecting section is located between the two guide columns.
[0015] Preferably, a limiting block for limiting the position of the upper connecting section is provided at one end of the lower connecting section away from the lower clamping section.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0025] like Figures 1 to 3 As shown, this embodiment provides a clamping fixture, including an articulated upper clamping arm 1 and a lower clamping arm 2, and an elastic member (not shown in the figure) arranged between the upper clamping arm 1 and the lower clamping arm 2, the upper clamping arm 1 is provided with an anti-scratch clamping block 3, and the lower clamping arm 2 is provided with a clamping limit platform 23, the clamping limit platform 23 is used to cooperate with the anti-scratch clamping block 3 to clamp the flexible conductive member 5, and the clamping limit platform 23 is used to limit the reinforcement plate 6 at the plug-in end of the flexible conductive member 5 in the plug-in direction.
[0026] The anti-scratch clamping block 3 in this embodiment can effectively avoid the problem of scratches on the flexible conductive part 5 caused by the clamping process. The clamping limit platform 23 can limit the reinforcement plate 6 at the plug-in end of the flexible conductive part 5 in the plug-in direction to avoid the problem of breakage of the flexible conductive part 5 caused by clamping deviation. The setting of the anti-scratch clamping block 3 and the clamping limit platform 23 greatly reduces the risk of damage to the flexible conductive part 5 and ensures the yield of the flexible conductive part 5.
[0027] In this embodiment, the height H of the clamping limit platform 23 is not less than the thickness D of the reinforcing plate 6, that is, H≥D. If D>H, the flexible conductive member 5 will inevitably bend near the reinforcing plate 6 during the clamping process, which may easily cause damage. However, if H≥D is set, the problem of damage to the flexible conductive member 5 caused by bending during the clamping process is avoided.
[0028] Specifically, the height H of the clamping and limiting platform 23 is 0.02 mm greater than the thickness D of the reinforcing plate 6. Such a setting effectively ensures the clamping and limiting effects, and prepares for the smooth insertion of the flexible conductive member 5.
[0029] In order to prevent the anti-scratch clamping block 3 from scratching the flexible conductive member 5 during the clamping process, in this embodiment, the anti-scratch clamping block 3 is preferably made of plastic, and the corners of the anti-scratch clamping block 3 are all rounded.
[0030] Since POM (polyoxymethylene) material is an engineering plastic with the advantages of high strength, high rigidity, good elasticity, good wear resistance and the like, the anti-scratch clamping block 3 in this embodiment is preferably made of POM material. Of course, the anti-scratch clamping block 3 may also be made of other engineering plastics such as PA (nylon), PC (polycarbonate), PETP (polyester), etc., depending on actual needs, and this embodiment does not impose any restrictions on this.
[0031] The upper clamp arm 1 in this embodiment includes an upper connecting section 11 and an upper clamping section 12 set at a first angle a, and the lower clamp arm 2 includes a lower connecting section 21 and a lower clamping section 22 set at a second angle b. The upper connecting section 11 is hinged to the middle of the lower connecting section 21, the anti-scratch clamping block 3 is set at the clamping end of the upper clamping section 12 by screws, and the clamping limit platform 23 is protrudingly set at the clamping end of the lower clamping section 22. By setting the upper clamp arm 1 and the lower clamp arm 2 as a bending structure, the clamping fixture meets the ergonomic design requirements, so that the operator does not need any active adaptation physically and mentally, thereby minimizing the fatigue caused by using the clamping fixture.
[0032] In this embodiment, the first angle a is preferably 165° and the second angle b is 170°. Of course, the first angle a and the second angle b can also be designed to be other angles, depending on actual needs, and this embodiment does not limit this.
[0033] In order to prevent the upper clamping arm 1 and the lower clamping arm 2 from being clamped in an angular manner, a clamping guide structure is provided between the upper connecting section 11 and the lower connecting section 21 in this embodiment.
[0034] Specifically, the clamping guide structure includes two guide posts 24 arranged on the lower connecting section 21 . The two guide posts 24 are arranged on opposite sides of the lower connecting section 21 , and the two guide posts 24 extend toward the direction where the upper connecting section 11 is located. The upper connecting section 11 is located between the two guide posts 24 .
[0035] In order to facilitate pressing the upper clamping arm 1 , in this embodiment, a limiting block 25 for limiting the upper connecting section 11 is provided at one end of the lower connecting section 21 away from the lower clamping section 22 .
[0036] In this embodiment, the upper connecting section 11 has an upper hinge seat, and the lower connecting section 21 has a lower hinge seat, and the upper hinge seat and the lower hinge seat are hinged via a hinge shaft 4. With such an arrangement, the upper connecting section 11 and the lower connecting section 21 are rotatably connected.
[0037] Specifically, the upper hinge seat includes two upper hinge ears 13 set at intervals, and the lower hinge seat includes two lower hinge ears 26 set at intervals. The two upper hinge ears 13 are located on the inner side of the two lower hinge ears 26. The hinge shaft 4 is passed through the two upper hinge ears 13 and the two lower hinge ears 26, and the two ends of the hinge shaft 4 are axially limited by the retaining spring 7 respectively.
[0038] Since a torsion spring is a coil spring that generates torque or rotational force and is more suitable for the clamping fixture, the elastic member in this embodiment is preferably a torsion spring, which is sleeved on the hinge shaft 4. Of course, a commonly used compression spring can also be selected. When the elastic member is a compression spring, the compression spring needs to be arranged on the inner side of the upper connecting section 11 and the lower connecting section 21, and the two ends of the compression spring are respectively connected to the upper connecting section 11 and the lower connecting section 21.
[0039] In the clamping jig of this embodiment, the upper clamping section 12 and the lower clamping section 22 are separated in a natural state. When the clamping jig is used to plug the flexible conductive member 5 and the connector of the substrate, the operator holds the clamping jig in a pen-like state, and ensures that the anti-scratch clamping block 3 and the clamping limit platform 23 of the clamping jig are in the clamping area (such as Figure 3 After the upper connecting section 11 and the lower connecting section 21 are aligned with each other, the thumb and the index finger simultaneously apply force to press the upper connecting section 11 and the lower connecting section 21 so that the anti-scratch clamping block 3 and the clamping limit platform 23 cooperate with each other to clamp the flexible conductive member 5, and then align the clamped flexible conductive member 5 with the connector, and plug the plug-in end of the flexible conductive member 5 into the connector. During the plug-in process, the clamping limit platform 23 limits the reinforcing plate 6 of the plug-in end of the flexible conductive member 5 in the plug-in direction, thereby ensuring smooth plug-in of the flexible conductive member 5 with the connector without damaging the flexible conductive member 5.
[0040] The above is only one embodiment of the clamping fixture of the utility model, and there are more embodiments that are not described here. In summary, the clamping fixture of the utility model effectively solves the problems of scratches and folds of the flexible conductive part 5 during the plug-in process, greatly reduces the risk of damage to the flexible conductive part 5, and ensures the yield of the flexible conductive part 5.
[0041] The present utility model is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative labor are all within the protection scope of the present utility model.
