Description

TECHNICAL FIELD

[0001] The utility model belongs to printed board installation technical field especially relates to a connector butt joint fixed structure. BACKGROUND

[0002] In the manufacturing of modern electronic equipment, the development of connector technology is particularly important. As a new type of connection method, the male-female connector gradually gains application in various electronic products due to its easy operation, high reliability, and durability. The male-female connector is usually composed of a male end with a small hook-shaped burr and a female end with a ring-shaped fluff, and the connection is achieved through hook-fluff interlocking. This design not only ensures the stability of the connection, but also makes the connection and separation operation very simple, suitable for frequent plugging occasions.

[0003] Flexible printed circuit board (FPC) is widely used in modern electronic products such as smartphones, tablets, and wearable devices due to its lightness, flexibility, and high temperature resistance. FPC realizes flexible connection of circuits by etching conductive patterns on a thin film substrate. Compared with traditional rigid circuit boards, FPC can adapt to complex three-dimensional wiring requirements and significantly save space and weight.

[0004] The butt joint and fixation of the male-female connector and FPC is a key technical challenge. The male-female connector is usually fixed by pressing onto the surface mount pads of the printed board to achieve electrical connection and fixation. This pressing method utilizes the hook-fluff structure of the male-female connector to achieve stable contact with the surface of the FPC and form a reliable electrical connection after applying a certain pressure. However, due to the flexible nature of FPC, ensuring the mechanical strength and electrical stability of the connection is a key problem in design.

[0005] As shown in Figure 4 , the existing connection technology usually uses a single-end fixation method, but this method has its limitations. End fixation is difficult to maintain stability over a long period of use and is difficult to provide sufficient mechanical strength, making it prone to loosening under vibration or external force. This affects the electrical performance of the butt joint. Therefore, an innovative fixation method for the butt joint of the male-female connector and FPC is needed, which can ensure the reliability and long-term stability of electrical connection, adapt to the flexible nature of FPC, simplify the assembly process, and reduce production costs.

[0006] The patent document with the publication number CN206864766U discloses a connecting mechanism of rigid-flexible printed board, which sets an array connector on the rear panel, sets a contact area on the upper capacitor board, wave control board and lower capacitor board, and realizes the modular conversion between the rear panel and multiple printed boards through the first rigid connecting plate, flexible belt and second rigid connecting plate of the rigid-flexible connecting belt.
