[0001] The utility model relates to a connector module, in particular to a connector module which is fixed to a circuit board without welding means and can stably keep a connector component in a current assembly position by rotating a locking piece, and an electronic device with the connector module. Background Art

[0002] Connector refers to all connection elements and their accessories used in electronic signal and power transmission. Its main function is to establish and maintain connections between circuits. It is not only responsible for transmitting power, but also covers data transmission. It is an important component in any modern electronic system. From mobile phones, computers to large industrial machinery and equipment, all rely on connectors to complete their basic functions.

[0003] However, despite their critical functionality, connectors are still one of the most vulnerable components in electronic devices. Generally speaking, connectors are usually fixed to circuit boards by welding. "Welding" provides a stable and durable connection for the connector, ensuring the reliability and performance of the electronic device. However, this method also brings significant disadvantages. Specifically, when a connector fails due to long-term use, physical damage or other reasons, it becomes extremely difficult to replace because it is welded to the circuit board. In most cases, professional equipment and technical knowledge are often required for disassembly and re-welding in order to install a new connector. For consumers, this usually means that the entire electronic device must be sent back to the manufacturer or a professional repair center for repair, which not only increases the complexity of the repair, but also increases the money and time cost of the repair, and causes trouble in using the electronic device.

[0004] In addition, the practice of soldering connectors also poses a challenge to the environment. When a connector is damaged, it is difficult to replace it, and in many cases the entire circuit board or even the entire device will be discarded, which puts great pressure on the environment. In today's society, with the increasing awareness of sustainable development and environmental protection, this practice is no longer in line with environmental protection requirements. Therefore, the industry has begun to explore more environmentally friendly and sustainable solutions to solve the problems of connector use and maintenance, which can promote the entire electronics manufacturing industry to develop in a more environmentally friendly and efficient direction.

When the insertion position is not completely correct, the guide bar 211 can first abut against the rear side of the connector component 3 (or the mounting housing 33). Therefore, the user can adjust the position of the connector component 3 by feel until the guide bar 211 is connected to the corresponding guide groove 335. After that, the user can quickly insert the connector component 3. During the aforementioned process, the guide bar 211 can play a guiding role, so that the connector component 3 cannot be significantly skewed or deviated from the correct installation position, thereby making the position of the plug-in port 333 of the connector component 3 correctly aligned with the side edge of the circuit board 13, until the side edge of the circuit board 13 is embedded in the plug-in port 333 and clamped between these metal terminal groups 315.

Figure 8BAs shown in FIG. 1 , when the connector component 3 is pulled outward, the locking portion 42 is blocked by the groove wall of the positioning groove 20, thereby preventing the connector component 3 and the positioning mechanism 2 from being separated from each other, thereby ensuring that the connector component 3 is stably positioned on the device body 1. Furthermore, when the user wants to remove the connector component 3, as long as the locking member 4 is rotated from the locking position to the releasing position, the locking portion 42 will be separated from the positioning groove 20, so that the connector component 3 can be separated from the positioning mechanism 2 and pulled out of the device body 1.

[0072] Please also refer to Figures 1 to 3 As shown, in this embodiment, the area of ​​the circuit board 13 corresponding to the connector component 3 can also be recessed to form a receiving space 130, so that the circuit board 13 has more design space, and the area of ​​the circuit board 13 close to the receiving space 130 can also have a limiting and auxiliary guiding effect, so that when the connector component 3 is inserted crookedly, it can be blocked by the area of ​​the circuit board 13 close to the receiving space 130. In addition, in the form of the aforementioned circuit board 13, the frame 21 is respectively provided with a shoulder 213 on the outer side of the two arms, and the shoulder 213 can be attached to the top side of the circuit board 13, and the local part of each arm can extend into the receiving space 130 of the circuit board 13 (such as Figure 3 As shown), so that the positioning of the frame 21 is more stable.
