Description

Technical Field

[0001] This application relates to a connector for a substrate. Background Technology

[0002] Board connectors, an indispensable part of electronic products, feature fast and stable transmission, low loss, and high fidelity, acting as a bridge for communication in electronic circuits. The development of 4G and 5G has accelerated the iteration speed of consumer electronics products. The rapid development of multi-functional modules in smartphones and wearable devices has promoted the development of board connectors. Modules such as displays, touchscreens, antenna connections, battery connections, microphone connections, and cameras all require board-to-board connections. Therefore, smart devices place high demands on the miniaturization, stability, and reliability of board connectors.

[0003] Currently, the mainstream connectors on the market include 0.35mm and 0.30mm pitch substrate connectors. In recent years, brands have begun to launch and mass-produce 0.175mm pitch substrate connectors. With the development of technology, the overall height, width, length and pitch between terminals of substrate connectors are getting smaller and smaller, and the overall manufacturing process is becoming more and more difficult.

[0004] Therefore, it is indeed necessary to design a new solution to overcome the aforementioned deficiencies in the existing technology. Utility Model Content

[0048] The following describes a method for manufacturing a connector for a substrate according to this application. The manufacturing method includes at least the following steps: S1: providing a metal assembly made by stamping and bending a metal plate, the metal assembly including the terminal 2, the end armor 3, and a connector 5 integrally connecting the second leg 23 of the terminal 2 and the second extension leg 33 of the end armor 3; S2: forming the insulating body 1 on the metal assembly by integral injection molding, and the insulating body 1 having the process hole 10; S3: removing the connector 5 by cutting.

[0049] In the connector for the substrate of this application, the terminal 2 and the end armor 3 are connected as a single unit by a connector 5. During the manufacturing process, the terminal 2, the end armor 3, and the connector 5 are formed from the same metal sheet by stamping and bending. A process hole 10 is designed and formed during the integral injection molding of the insulating body 1, allowing the connector 5 exposed in the process hole 10 to be removed after the insulating body 1 is formed. This ensures more stable positioning of the terminal 2 and the end armor 3 during integral injection molding with the insulating body, achieving positioning at the first foot 22, the second foot 23, the first extension foot 32, and the second extension foot 33. In particular, it allows for more precise fixing of the two free ends of the approximately n-shaped contact segment 21 to the insulating body 1, preventing misalignment of any foot during injection molding due to positioning issues or excessive temperature.

[0050] Furthermore, to better position the terminal 2 during the injection molding of the insulating body 1, a recessed groove 102 is formed on the lower surface 101 of the insulating body 1 between the two free ends of the generally n-shaped contact segment 21. The inner surface of one of the free ends of the generally n-shaped contact segment 21 is exposed into the recessed groove 102, while the inner surface of the other free end of the generally n-shaped contact segment 21 is not exposed into the recessed groove 102. This design serves two purposes: firstly, it positions the terminal 2 during the injection molding of the insulating body 1; secondly, it ensures the flow properties of the liquid plastic fluid forming the insulating body 1. In a preferred embodiment, the recessed groove 102 extends along the first direction, covering the entire length of the sidewall 11 along the indicated first direction.

[0051] Furthermore, the overall structural design of the end armor component 3 allows the end armor component 3 and multiple terminal components 2 to be formed from the same metal sheet through stamping and bending. It also ensures a more stable and reliable bond between the end armor component 3 and the insulating body 1. The connector for the substrate of this application has a robust and stable overall structure, is simple to manufacture, low in cost, and suitable for large-scale mass production.
