Description
Technical Field
[0001] The utility model relates to the technical field of display modules, and in particular to a module FPC structure that is convenient for operation. Background Art
[0002] Please refer to Figure 1 The display module used in wearable devices such as smart watches includes components such as display glass, module FPC 100, and driver IC. The module FPC 100 is bound to the display glass to drive the display. Due to space limitations on the wearable device, it is bent and stacked with the touch FPC used to drive the touch control. In addition, the module FPC usually adopts a ZIF connection interface structure. Due to the small plug-in position, employees may experience inconvenience and low efficiency during operation, and the module FPC may be easily pulled, causing tearing.
[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a modular FPC structure that is easy to operate.
[0005] The technical solution of the present invention is as follows: The present invention provides a module FPC structure that is easy to operate, including: a main body, the main body including a first connection end, a main body and a second connection end, the first connection end is used to bind and connect with the display glass, the second connection end is a ZIF plug-in end, the first connection end and the second connection end are respectively located at both ends of the main body, and the main body is further formed with a first hollow part and a second hollow part with openings facing opposite directions between the first connection end and the second connection end, the first hollow part and the second hollow part are located on the side of the main body close to the second connection end, and the first hollow part is closer to the first connection end than the second hollow part, the inner side of the first hollow part is formed with a first transition arc at a position close to the second connection end, the center line of the first transition arc and the bending center line of the second connection end are on the same central axis, the inner side of the second hollow part is formed with a second transition arc at a position close to the first connection end, the inner side of the second hollow part is formed with a third transition arc at a position close to the second connection end, and the distance between the inner edge of the third transition arc and the center line of the first transition arc is greater than or equal to 2.5 mm.
[0006] Furthermore, the body further includes a third connection end, and the third connection end is provided on the main body portion for connecting to the NFC coil.
[0007] Furthermore, the front-to-back length of the second hollow portion is greater than or equal to 1.5 mm.
[0008] By adopting the above scheme, the beneficial effect of the utility model is that the first hollow portion and the second hollow portion, as well as the first transition arc, the second transition arc and the third transition arc are designed on the module FPC, and the center line of the first transition arc is set to be on the same central axis as the bending center line of the second connection end, which not only effectively reduces the stress generated during bending and facilitates the bending and plugging operations, but also avoids the problem of FPC tearing during bending.

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] Please refer to Figure 2 and Figure 3In this embodiment, the utility model provides a module FPC structure that is convenient for operation, including: a main body, the main body including a first connection end 1, a main body 2 and a second connection end 4, the first connection end 1 is used to bind and connect with the display glass, the second connection end 4 is a ZIF plug-in end, the first connection end 1 and the second connection end 4 are respectively located at the two ends of the main body 2, and the main body 2 is further formed with a first hollow part 5 and a second hollow part 8 with openings facing opposite directions between the first connection end 1 and the second connection end 4. The first hollow part 5 and the second hollow part 8 are located on the side of the main body 2 close to the second connection end 4, and the first hollow part 5 is closer to the first connection end 1 than the second hollow part 8. This structural design makes the main body in a long and bent shape at a position close to the second connection end 4, which is more convenient for ZIF plug-in bending and other actions during subsequent assembly. The inner side of the first hollow portion 5 is concavely formed with a first transition arc 6 at a position close to the second connecting end 4. The first transition arc 6 is a circular arc with a radius of 0.5 mm. The center line S of the first transition arc 6 and the bending center line of the second connecting end 4 are on the same central axis, which can effectively reduce the bending resistance. The front-to-back length L of the second hollow portion 8 is 1.6 mm. The inner side of the second hollow portion 8 is formed with a second transition arc 7 at a position close to the first connecting end 1. The inner side of the second hollow portion 8 is formed with a third transition arc 9 at a position close to the second connecting end 4. The distance W between the inner edge of the third transition arc 9 and the center line of the first transition arc 6 is 2.6 mm, which can facilitate employees' operation and improve efficiency.
[0014] Furthermore, the body further includes a third connection terminal 3, which is provided on the main body 2 and is used to connect to the NFC coil.
[0015] To sum up, the beneficial effect of this solution is that by designing the first hollow portion and the second hollow portion, as well as the first transition arc, the second transition arc and the third transition arc on the module FPC, and setting the center line of the first transition arc to be on the same center axis as the bending center line of the second connection end, it not only effectively reduces the stress generated during bending and facilitates the bending and plugging operations, but also avoids the problem of FPC tearing during bending.
[0016] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
