[0029] Please refer to Figure 1 and Figure 2The present embodiment discloses an extra-long FPC patch fixture, which is suitable for an FPC board 10 having a patch area and a non-patch area, and includes a support member 100 and a protective cover 200, wherein the support member 100 can be a metal plate or a plastic plate, and the support member 100 has a bearing portion 111 and a hollow portion 112 arranged at intervals, for example, the number of the bearing portions 111 is 4, the number of the hollow portions 112 is 3, and a hollow portion 112 is arranged between two adjacent bearing portions 111, and a positioning portion 113 is arranged on the bearing portion 111 of the support member 100, and the support member 100 has a plurality of hollow portions 112 arranged at intervals. The bearing portion 111 of the support 100 is used to accommodate the patch area of ​​the FPC board 10 and is positioned and limitedly connected through the positioning portion 113. For example, the positioning portion 113 can be a positioning column, and the FPC board 10 is positioned and limitedly connected through the positioning column. For example, the positioning portion 113 can be a positioning hole and a pin, and the FPC board 10 is positioned through the positioning hole, and the FPC board 10 is limitedly connected through the pin inserted in the positioning hole. It is worth mentioning that the FPC board 10 is provided with a plurality of process holes or hollow structures, and the process holes or hollow structures are used for positioning and matching. The hollow portion 112 of the support 100 is used to avoid the non-patch area of ​​the FPC board 10. The protective cover 200 is connected to the bottom of the support 100 and is at least located below the hollow portion 112 of the support 100. A accommodating cavity for accommodating the non-patch area of ​​the FPC board 10 is formed in the protective cover 200. In this way, the bearing portion 111 of the support member 100 supports the patch area of ​​the FPC board 10, and the hollow portion 112 avoids the non-patch area of ​​the FPC board 10, and is accommodated in the accommodating cavity formed by the protective cover 200, so that the longer FPC board 10 can be folded and shortened to meet the size requirements of the device patch working area, and the protective cover 200 can protect the folded part of the FPC board 10 to avoid damage during processing.

[0030] In some application examples, a positioning groove 114 is provided in the bearing portion 111 of the support member 100, and the depth of the positioning groove 114 is adapted to the thickness of the FPC board 10. The positioning groove 114 can facilitate the positioning of the FPC board 10, and when the FPC board 10 is placed in the positioning groove 114, the FPC board 10 can be limited and fixed.

[0031] The positioning groove 114 may be a single groove, or, please refer to Figure 2The positioning groove 114 includes a first recess 1141 and a second recess 1142. The second recess 1142 is connected to the first recess 1141 and extends to the adjacent hollow portion 112. The first recess 1141 and the second recess 1142 cooperate to adapt to the structure of the FPC board 10. The width of the first recess 1141 is greater than the width of the second recess 1142 to form a clamping and limiting structure. After the FPC board 10 is placed in the positioning groove 114, the first recess 1141 can clamp and limit the FPC board 10, making the placement of the FPC board 10 more reliable. Among them, the positioning portion 113 is arranged in at least one of the first recess 1141 or the second recess 1142. For example, the positioning portion 113 is arranged in the first recess 1141, or the positioning portion 113 is arranged in the second recess 1142. For example, both the first recess 1141 and the second recess 1142 are provided with the positioning portion 113, which can be flexibly arranged according to the structure such as the process hole or hollow area of ​​the FPC board 10 to meet the positioning and limiting requirements of the FPC board 10.

[0032] In order to improve the processing efficiency, a plurality of accommodating areas 110 are provided on the support member 100, and each accommodating area 110 is provided with a bearing portion 111 and a hollow portion 112. For example, please refer to Figure 1 , one accommodating area 110 is used to place an FPC board 10, each FPC board 10 has 4 patch areas and 3 non-patch areas, so that 4 bearing parts 111 and 3 hollow parts 112 are arranged on the support 100 to carry the FPC board 10 and fold the FPC board 10 to meet the length requirements of patch processing. Exemplarily, multiple accommodating areas 110 are arranged side by side on the support 100 to facilitate the processing of the support 100 and to facilitate the neat placement of the FPC board 10 on the support 100 when in use. Among them, in some application examples, the hollow parts 112 of adjacent accommodating areas 110 are separated from each other by a connecting structure to improve the structural strength of the support 100, while in other application examples, for the support 100 with higher structural strength, the hollow parts 112 of adjacent accommodating areas 110 are connected to each other, that is, the hollow parts 112 of multiple accommodating areas 110 are processed into a hollow area to facilitate the molding of the hollow parts 112.

[0033] In order to adapt to multiple types of support members 100, the protective cover 200 and the support member 100 are detachably connected. Exemplarily, for the same patch device, the size of the patch working area is fixed, that is, the maximum size of the support member 100 and the protective cover 200 is fixed, and for different types of FPC boards 10, there may be different positions of the patch area and the non-patch area. For this reason, the bearing portion 111 and the hollow portion 112 of the support member 100 can be adaptively designed, and the protective cover 200 does not need to be changed, and can be shared between multiple types of FPC boards 10. Therefore, through the detachable connection between the protective cover 200 and the support member 100, such as snap-on or connection through fasteners such as screws, bolts, etc., the protective cover 200 can be replaced between supports 100 of different structures, thereby improving the versatility of the protective cover 200 and saving the processing cost of the jig.

[0034] Please refer to Figure 1 In some application examples, the protective cover 200 covers the bottom of the support member 100, that is, covers the bearing portion 111 and the hollow portion 112 of the support member 100, so as to facilitate the molding of the protective cover 200. Figure 3 In other application examples, the protective cover 200 covers the hollow portion 112 of the support member 100. For example, the support member 100 is provided with a plurality of hollow portions 112 arranged at intervals, and a protective cover 200 is provided corresponding to each hollow portion 112; for another example, the hollow portions 112 between the plurality of accommodating areas 110 of the support member 100 are interconnected, and the protective cover 200 covers the plurality of interconnected hollow portions 112. In this way, the size of the protective cover 200 can be reduced, saving processing costs.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
