In the terminal device disclosed in the embodiment of the present disclosure, the circuit board 200 of the terminal device includes a tongue 220, and a socket terminal 230 is provided on the tongue 220. Since the tongue 220 is electrically connected to the circuit board body 210, the socket terminal 230 and the terminal device The circuit board 200 is electrically connected, and the tongue 220 extends from the inner cavity 120 of the housing 100 into the opening 110. The housing 100 serves as an integral peripheral housing formed by the tongue 220 and the socket terminal 230, thereby forming a data socket. It can be seen that the terminal device disclosed in this embodiment makes full use of its constituent components, and transforms its own components to form a data socket. Compared with the single data socket in the related art, the structure and formation process of the data socket formed by the terminal device disclosed in this embodiment are relatively simple, and injection molding in multiple processes and assembly of many component parts are not required. Therefore, the cost of the data socket formed by the terminal device disclosed in this embodiment is lower.

On the premise that both sides of the tongue 220 are provided with socket terminals 230, in order to prevent mutual interference of the socket terminals 230 on both sides, in an alternative solution, the tongue 220 may include a signal isolation layer 221, which isolates signals The layer 221 is located between the socket terminals 230 disposed on both sides of the tongue 220, respectively, and thus can play a role in signal isolation, thereby preventing mutual interference between the socket terminals 230 on both sides.

In this embodiment, the tongue 220 is a part of the circuit board 200, and the tongue 220 and the circuit board body 210 may be an integrated structure, that is, processed by a whole circuit board. Of course, the tongue 220 and the circuit board body 210 can be fixedly connected by an assembly process (such as welding), and at the same time, the tongue 220 and the circuit board body 210 are electrically connected.

The circuit board 200 includes an insulating layer and a metal layer (for example, a copper layer). Optionally, the tongue 220 includes an insulating layer 222 and a metal layer laid in the insulating layer 222. The metal layer is the signal isolation layer 221 described above. This optional solution can make full use of the structural structure of the circuit board 200 itself, so that the metal layer contained in the circuit board 200 serves as a signal isolation layer 221 for isolating the socket terminals 230 on both sides, so that the metal layer can play multiple roles and achieve one multi-purpose Effect. At the same time, this method makes the formation process of the data socket simpler and lower cost.

The socket terminal 230 is a metal component. In an optional solution, the socket terminal 230 is an etched terminal. As described above, the circuit board 200 generally includes a multi-layer metal layer and an insulating layer that insulates two adjacent metal layers. In the process of preparing the socket terminal 230, the structure of the circuit board 200 can be improved through the circuit board etching process, so that the metal layer of the circuit board 200 is etched to form the socket terminal 230. Similarly, the socket terminal 230 of this structure is formed by The structure of the circuit board 200 itself is formed, so the structure is simple, the operation is easier, and the cost is lower.

In this embodiment, the socket terminal 230 may be made of copper or aluminum, and of course may be other metal materials. This embodiment does not limit the specific material types of the socket terminal 230.

The circuit board body 210 is fixedly connected to the tongue 220, and the two are generally of an integrated structure. The edge of the circuit board body 210 is generally a straight edge, and the tongue 220 may protrude from the straight edge of the circuit board body 210. For a more alternative solution, please refer to FIG. 5, a groove 211 is provided on the edge of the circuit board body 210, one end of the tongue 220 is fixed on the bottom surface of the groove 211, and the other end extends toward the notch of the groove 211.

The end connected to the circuit board body 210 may be provided with a positioning recess 223. The positioning recess 223 may be sleeved with a sealing ring 240. The sealing ring 240 is positioned in cooperation with the positioning notch 131, and is used to seal the shielding platform 130 and the tongue 220 The gap between. During the assembly process, the sealing ring 240 is first sleeved on the tongue 220, and is positioned and matched with the positioning recess 223. As the tongue 220 is inserted into the opening 110, the sealing ring 240 moves to the position where the positioning gap 131 is sealed and fitted Position, so as to achieve a manner of sealing between the shielding platform 130 and the tongue 220.
