Description

Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to a connector of FPC which is not easy to loosen. Background Art

[0002] In order to make the appearance of the whole smart watch more attractive to consumers, the customer structure UI and the whole machine casing are basically finalized first, which will make the functional parts inside the smart watch placed in a limited space. Since the appearance has been determined, the appearance of the connector and FPC has basically been finalized. However, with the use of customer products, the connector on the FPC will gradually become easy to warp up and loosen, resulting in poor connection. This is because we buckle the connector of the module on the motherboard connector, and when the connected male and female connectors are buckled together, the connector has a certain height, so the FPC where the connector is located will generate a pulling force at this height. Since the FPC is relatively short and the height of the connector affects the tension here, the FPC will be very large. In addition, during use, the display module will shake with the watch, and the connector on the FPC will be subjected to a greater pulling force, which makes the position of the connector easier to loosen, causing various display problems. Utility Model Content

[0015] Compared with the prior art, the utility model has at least the following advantages:

[0016] The utility model provides a FPC connector that is not easy to loosen. The FPC originally connected to the ZIF connector is changed into a flexible connecting plate. The flexible connecting plate is "U" shaped. Because the curved FPC can have a certain degree of stretchability during the application process, when the connector is buckled on the customer's motherboard connector, the pulling force on the connector will be well released, so that the connector will not be easily pulled up to cause poor connection. Without changing the structure finalized by the customer, the position of the connector can be more secure and not easy to loosen, preventing display problems. BRIEF DESCRIPTION OF THE DRAWINGS
