Description

Technical Field

[0001] This utility model relates to the field of data cable PCB board technology, and in particular to a PCB board structure for a retractable data cable. Background Technology

[0002] Traditional data cables simply use connectors at both ends to connect to devices, enabling data transfer and charging between different devices. However, when traditional data cables are long, they are inconvenient to store and prone to tangling, causing inconvenience.

[0003] Therefore, data cable structures with retractable storage features have emerged. For example, existing patent publication number CN221428104U discloses a charging head with a retractable data cable. By wrapping one end of the data cable around a housing and utilizing elastic elements such as spring contacts, it can be stored in the housing. This allows the cable to be stored away when not in use. The device includes a fixed PCB and a rotating PCB. The data cable is connected to the data connector so that when the data connector is pulled, the data cable drives the rotating PCB to rotate on the fixed PCB. During the rotation of the rotating PCB, the connector spring contacts on the rotating PCB always maintain contact with the annular contact points on the fixed PCB to ensure conductivity. However, existing connector spring contacts or terminal structures are mainly fixed directly to the PCB by soldering. During the rotation and friction with the fixed PCB, the solder joints may loosen or detach, resulting in poor contact and affecting the use of the data cable. Utility Model Content

[0015] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2A PCB board structure for a retractable data cable includes a PCB body 10 and a terminal group 20. The surface of the PCB body 10 is provided with a mounting groove 11. The terminal group 20 includes a fixing frame 21 and a plurality of contact springs 22. The contact springs 22 are arranged in the fixing frame 21, and one end of the contact springs 22 extends out of one side of the fixing frame 21. The fixing frame 21 is fixed in the mounting groove 11. The PCB body 10 is provided with a contact point 12 corresponding to one end of the contact spring 22. One end of the contact spring 22 is soldered and fixed to the contact point 12.

[0016] First, the contact spring 22 is fixed to one side of the fixing frame 21 by injection molding to form the terminal group 20. The PCB body 10 has a mounting groove 11 on its surface. By fixing the fixing frame 21 in the mounting groove 11, the contact spring 22 is fixed to the PCB body 10. Furthermore, one end of the contact spring 22 is soldered to the contact point 12 on the PCB body 10 to make the contact spring 22 electrically connected to the PCB body 10, which can also improve the connection strength and form a double fixing method. This ensures that the contact spring 22 on the PCB body 10 has good stability when it contacts and rotates with other PCB boards. At the same time, the mounting groove 11, in conjunction with the fixing frame 21, plays a better role in limiting and fixing the contact spring 22, reducing the thickness it occupies.

[0017] Please refer to Figure 3 In the above scheme, a number of contact springs 22 are arranged between partitions 212. The partitions 212 and the fixing frame 21 are integrally formed. The partitions 212 separate the contact springs 22 to prevent adjacent contact springs 22 from contacting each other and causing a short circuit. The fixing frame 21 has a flange 211 on its edge. The flange 211 is engaged with the surface of the PCB body 10. The flange 211 can limit the installation of the fixing frame 21 and the mounting groove 11, and also increase the contact area between the two to improve the stability of the connection.

[0018] The contact spring 22 includes a fixing part 221 and a contact part 222. The fixing part 221 and the contact part 222 are integrally formed. The fixing part 221 is embedded in the fixing frame 21 and extends to the surface of the PCB body 10. It is welded and fixed to the contact 12. The contact part 222 has a V-shaped structure. The contact part 222 passes through the mounting groove 11 and protrudes from the lower end of the PCB body 10. The contact part 222 can make contact with other PCB boards. At the same time, it avoids the situation where two PCB boards need to be in contact to achieve conductivity. It reduces the friction between PCB boards and improves the smoothness of rotation.

[0019] Furthermore, reinforcing ribs 223 are provided on both the upper and lower surfaces of the connection between the fixing part 221 and the contact part 222, so that the contact part 222 can have sufficient force to maintain contact when it comes into contact with other PCB boards, and at the same time, it can prevent the contact part 222 and the fixing part 221 from breaking or deforming, thereby improving the overall service life.

[0020] The fixing part 221 has serrated edges to improve the gripping force between the fixing part 221 and the fixing frame 21 during injection molding, thereby improving the overall stability.

[0021] In this embodiment, there are three terminal groups 20. The terminal groups 20 are arranged at intervals of 120 degrees around the center of the PCB body 10, thereby improving the overall connection stability and better meeting the stability of rotation and conduction when the telescopic data cable is stretched or wound.

[0022] This utility model provides a PCB board structure for a retractable data cable. First, the contact spring is fixed to one side of the fixing frame by injection molding to form a terminal group. The surface of the PCB body is provided with a mounting groove. By fixing the fixing frame in the mounting groove, the contact spring is fixed to the PCB body. Furthermore, one end of the contact spring is soldered to the contact point on the PCB body to make the contact spring electrically connected to the PCB body, which can also improve the connection strength and form a double fixing method. This ensures that the contact spring on the PCB body has good stability when it contacts and rotates with other PCB boards. At the same time, the mounting groove, together with the fixing frame, plays a better role in limiting and fixing the contact spring, reducing the thickness occupied.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
