Description

Technical Field

[0001] The present application relates to the technical field of data cables, and in particular to a connector module and a data cable. Background Art

[0002] With the popularity of various electronic products, such as mobile phones, tablet computers, shavers and other charging devices, people need to configure various data cables to match. Especially when people go out, when they carry both Lightning interface and TYPE C interface charging series products, they need at least two data cables, and the charger is generally divided into USB-A and USB-C output ports. Therefore, people have developed a multi-connector rotatable data cable, and a connector module including multiple types of connectors is set at the connection between the data cable and the electronic product to reduce the number of data cables carried.

[0003] However, the existing connector modules are all equipped with multiple spaced metal rings to form a metal disk, and then multiple contact terminals are arranged to be connected to the metal rings accordingly. Under the condition of meeting the electrical connection and protocol communication requirements of the connector, the contact terminal or the metal ring is rotated, and then the connector module can be rotated relative to the data line body, so as to switch interfaces of different models. Since each contact terminal is connected to a different functional circuit, terminals of different functional circuits cannot contact the same metal ring. Since different connectors have multiple different functional circuits, different types of connectors are made into the same connector module, which will increase the number of contact terminals, and the number of metal rings on the metal disk will increase accordingly, which will cause the metal disk to be made very large, affecting the volume of the data line connector. Moreover, the contact terminal and the metal disk are in elastic contact in the form of surface connection. When the disk rotates clockwise or counterclockwise, it will drive the contact terminal to deviate in the direction of movement. Over time, it is easy to cause the contact terminal to deform and cause poor contact.

[0004] Based on this, it is necessary to improve the structure of the existing connector module to solve the above problems. Utility Model Content

The present application may be an embodiment implemented in other ways. Moreover, it should be understood that the words and terms used herein are only used for descriptive purposes and should not be interpreted restrictively. The words "including", "comprising", "having" and the like used herein are meant to include the items listed thereafter, their equivalents and other additional items. In particular, when describing "a certain element", the present application does not limit the number of the element to one, but may also include multiple elements.

[0026] Please also refer to Figures 1 to 5 As shown, the present application provides a connector module 14 and a data line 10, which can be used for various charging devices that require data lines, such as mobile phones, tablet computers, Bluetooth headsets, and shavers. The data line 10 includes a line body 12 and a connector module 14 connected to the line body 12. The connector module 14 can be used to connect to a charging device or a charger. The connector module 14 includes a bracket 16, a rotating shaft 18 provided on the bracket 16, and a rotating joint 20 that can rotate relative to the rotating shaft 18. The rotating shaft 18 is cylindrical as a whole. The bracket 16 is provided with a first circuit module. The rotating joint 20 includes a second circuit module and a conductive terminal 22. The conductive terminal 22 is, for example, a spring structure with a curved design. The circumferential side of the rotating shaft 18 is provided with a conductive member 24 electrically connected to the first circuit module. One end of the conductive terminal 22 is electrically connected to the second circuit module, and the other end is in contact with the conductive member 24 to achieve conductive connection. Among them, the line body 12 is connected to the first circuit module in the connector module 14.

[0027] It should be pointed out that the prior art is to set the conductive metal ring on the axial end side of the metal disk, while the connector module 10 of the present application is designed with a rotating contact circular shaft, the conductive terminal 22 is located on the radial outside of the rotating shaft 18, and the conductive member 24 is arranged on the radial circumferential side of the rotating shaft 18 to form an axial connection with the conductive terminal 22, so that the conductive terminal 22 is always located in the rotating contact area of ​​the conductive member 24, and the rotary joint 20 can rotate 360 ​​degrees. The conductive member 24 is arranged on the radial circumferential side of the rotating shaft 18, and each conductive member 24 is connected to a functional circuit. When the rotary joint 20 includes multiple communication protocol circuits, multiple conductive members 24 are arranged along the axial direction of the rotating shaft 18 and contact the conductive terminal 22 in the axial direction.
