Description

Technical Field

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

[0002] Existing retractable data cable structures mainly consist of a data cable body, a housing, and a winding assembly housed inside the housing. The data cable body is spirally wound around the winding assembly, with both ends extending out of the housing for stretching. The winding assembly enables automatic winding. However, to avoid damage to the internal winding assembly, both ends must be stretched simultaneously when extending the data cable. This can be inconvenient for stretching one end in some chargers or devices. Therefore, a PCB structure that allows for stretching from one side of the data cable is needed. Utility Model Content

[0003] The purpose of this utility model is to provide a PCB board structure for a retractable data cable, which uses two corresponding PCB board bodies that are connected to each other to meet the stretching requirements of one end of the existing retractable data cable.

[0004] The technical solution adopted by the PCB board structure for a retractable data cable disclosed in this utility model is:

[0005] A PCB board structure for a retractable data cable includes a first PCB board body and a second PCB board body. The first PCB board body has a first through hole in the middle and a contact ring is provided around the first through hole on the surface of the first PCB board body. The second PCB board body has a second through hole in the middle and the second through hole and the first through hole are coaxially arranged. The surface of the second PCB board body has a contact terminal, and the contact terminal contacts the contact ring to achieve electrical connection. A first solder contact point is also provided on one side of the first PCB board body.

[0006] As a preferred embodiment, the contact terminal includes a connecting block and a spring piece. The second PCB board body has a contact window corresponding to the contact terminal. The connecting block is fixed to the side of the second PCB board body away from the first PCB board body. One end of the spring piece is fixedly connected to the connecting block, and the other end of the spring piece extends through the contact window to abut against the contact ring.

[0007] As a preferred embodiment, the number of spring pieces is several, the spring pieces are fixed on the connecting block, the number of contact rings is the same as the number of spring pieces, the several contact rings are arranged to increase in size and spread outward from the center of the first through hole, and there are intervals between the several contact rings.

[0008] As a preferred embodiment, the spring extends to one end of the contact window in a V-shaped contact portion, and the bottom of the contact portion protrudes below the main body of the second PCB board and abuts against the contact ring.

[0009] As a preferred embodiment, the number of contact terminals is several, the contact terminals are arranged at intervals around the second through hole, and the surface of the second PCB board body is provided with a second solder contact point.

[0010] The beneficial effects of the PCB board structure for a retractable data cable disclosed in this utility model are as follows: In actual assembly and use, the first PCB board body is fixed in the housing, while the second PCB board body is rotatably disposed in the housing. The first and second PCB board bodies can rotate coaxially through a first through hole and a second through hole via other rotating shafts or other components. The first solder contact point on the first PCB board body can be used to connect a connector or other connecting device. The second PCB board body is electrically connected to the first PCB board body through contact terminals. The contact terminals can be connected to the wire, so that when the wire is stretched, it drives the second PCB board body to rotate, and the contact terminals rotate along the contact ring, ensuring that the first and second PCB board bodies always remain connected, ensuring data transmission of the data cable, and also fulfilling the requirement of stretching one end of the retractable data cable.

[0016] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0017] Please refer to Figures 1 to 4A PCB board structure for a retractable data cable includes a first PCB board body 10 and a second PCB board body 20. The first PCB board body 10 has a first through hole in the middle and a contact ring 11 is provided around the first through hole on the surface of the first PCB board body 10. The second PCB board body 20 has a second through hole in the middle and the second through hole and the first through hole are coaxially arranged. The surface of the second PCB board body 20 is provided with a contact terminal 21, which makes contact with the contact ring 11 to achieve electrical connection. A first solder contact point contact window 22 is also provided on one side of the first PCB board body.

[0018] In actual assembly and use, the first PCB board body 10 is fixed in the housing, while the second PCB board body 20 is rotatably disposed in the housing. The first PCB board body 10 and the second PCB board body 20 can rotate coaxially through a first through hole and a second through hole via other rotating shafts or other components. The first solder contact point contact window 22 on the first PCB board body 10 can be used to connect connectors or other connecting devices. The second PCB board body 20 is electrically connected to the first PCB board body 10 through contact terminals 21. Contact terminals 21 can be connected to wires, so that when the wires are stretched, the second PCB board body 20 is driven to rotate, and the contact terminals 21 rotate along the contact ring 11, ensuring that the first PCB board body 10 and the second PCB board body 20 always remain connected, ensuring the data transmission of the data cable, and also fulfilling the requirement of stretching one end of the telescopic data cable.

[0019] Please refer to Figure 5 The contact terminal 21 includes a connecting block 211 and a spring piece 212. The second PCB board body 20 has a contact window 22 corresponding to the contact terminal 21. The connecting block 211 is fixed to the side of the second PCB board body 20 away from the first PCB board body 10. One end of the spring piece 212 is fixedly connected to the connecting block 211, and the other end of the spring piece 212 extends through the contact window 22 and abuts against the contact ring 11.

[0020] By positioning the connecting block 211 and the spring piece 212 on the side away from the first PCB board body 10, the distance between the first PCB board body 10 and the second PCB board body 20 can be effectively reduced. Furthermore, the spring piece 212, through the hollow design of the contact window 22, can ensure that the spring piece 212 contacts the contact ring 11 on the first PCB board body 10. At the same time, the contact window 22 can also reserve rebound space for the spring piece 212, so that the spring piece 212 with better elasticity can be used for contact, ensuring a longer service life.

[0021] There are several spring contacts 212, which are fixed to the connecting block 211. The number of contact rings 11 is the same as the number of spring contacts 212. The contact rings 11 are arranged in a series of increasing sizes and spreading outwards from the center of the first through hole, and there are gaps between the contact rings 11. One end of the spring contact 212 extends to the contact window 22 and forms a V-shaped contact portion 212. The bottom of the contact portion 212 protrudes below the second PCB board body 20 and abuts against the contact ring 11.

[0022] The number of spring contacts 212, such as 6P and 8P, can be set according to the needs of different data lines, thereby forming different ground contact terminals 21. The number of contact rings 11 corresponds to the number of spring contacts 212, which can ensure that the first PCB board body 10 and the second PCB board body 20 can make normal contact and communication.

[0023] In the above scheme, there are several contact terminals 21, which are spaced around the second through hole, and the surface of the second PCB board body 20 is provided with second solder contact points 23. Multiple contact terminals 21 can be electrically connected to the second solder contact points 23 by wiring. The wires can be connected and fixed to the second PCB board body 20 through the second solder contact points 23, so as to achieve the purpose of connecting one wire to multiple contact terminals 21.

[0024] This utility model provides a PCB board structure for a retractable data cable. In actual assembly and use, the first PCB board body is fixed in the housing, while the second PCB board body is rotatably disposed in the housing. The first and second PCB board bodies can rotate coaxially through a first through hole and a second through hole via other rotating shafts or other components. The first solder contact point on the first PCB board body can be used to connect a connector or other connecting device. The second PCB board body is electrically connected to the first PCB board body through contact terminals. The contact terminals can be connected to the wire, so that when the wire is stretched, it drives the second PCB board body to rotate, and the contact terminals rotate along the contact ring, ensuring that the first and second PCB board bodies always remain connected, ensuring data transmission of the data cable, and also fulfilling the stretching requirement of one end of the retractable data cable.

[0025] 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.
