[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof.

[0031] This invention may be implemented in different forms and should not be limited to the embodiments mentioned below. However, these embodiments are provided to help to more fully understand the contents of this invention and to fully convey the scope of this invention to those skilled in the art. The same reference numerals will refer to similar elements throughout the text.

[0032] Figures 1 to 3 An embodiment of an adapter is shown. (Refer to...) Figures 1 to 3 The adapter includes a housing 1, a printed circuit board 2, a male connector 3, a female connector 4, a common mode choke element 5, and an electrostatic discharge protection element 6.

[0033] like Figure 3As shown, the printed circuit board 2 has a first signal line 21 and a second signal line 22. A male connector 3 is disposed at one end of the printed circuit board 2 and electrically connected to the first signal line 21 and the second signal line 22. A female connector 4 is disposed at the other end of the printed circuit board 2 and electrically connected to the first signal line 21 and the second signal line 22. A common-mode choke element 5 is disposed on the printed circuit board 2 and electrically connected to the first signal line 21 and the second signal line 22. An electrostatic discharge (ESD) protection element 6 is disposed on the printed circuit board 2. The ESD protection element 6 has a first end and a second end. The first end is electrically connected to the first signal line 21 or the second signal line 22, and the second end is electrically connected to the printed circuit board 2 and grounded to GND through the printed circuit board. The first signal line 21 and the second signal line 22 are each connected to an ESD protection element 6. The common-mode choke element 5 may include a common-mode choke coil for shielding electromagnetic interference (EMI); the ESD protection element 6 is used to prevent the circuit from being affected by electrostatic discharge (ESD). Both the common-mode choke element 5 and the electrostatic discharge protection element 6 can be based on known circuits or devices. Their structures are not the focus of this invention and will not be described in detail here.

[0034] Combination Figure 1 and Figure 2 As shown, the printed circuit board 2 is disposed within the housing 1. A portion of the male connector 3 and at least a portion of the female connector 4 are enclosed within the housing 1. Another portion of the male connector 3 protrudes outward from one end of the housing 1, and a portion of the female connector 4 (e.g., a slot for inserting other connectors) is exposed relative to the other end of the housing 1. In one example, the printed circuit board 2 comprises a single printed circuit board 2, with the male connector 3 and female connector 4 respectively disposed at opposite ends of the single printed circuit board 2.

[0035] It should be noted that no cables are installed in the housing 1, nor is the housing 1 connected to any cables. In other words, the male connector 3 and the female connector 4 are connected to the same printed circuit board 2, and signal transmission is achieved directly through the electrical connection on the printed circuit board 2 (including the first signal line 21 and the second signal line 22). This facilitates a compact adapter structure, reduces its size, and eliminates the need for additional connecting cables.

[0036] The outer casing 1 is a continuous single plastic component, injection molded to encapsulate the printed circuit board 2, male connector 3, and female connector 4. The male connector 3 protrudes outward from a first surface of the outer casing 1, while the female connector 4 protrudes relative to a second surface of the outer casing 1. The first and second surfaces may be the same or different. In the example shown in the accompanying drawings, the first and second surfaces are positioned opposite each other, with the male connector 3 and female connector 4 located on opposite sides of the outer casing 1. In other embodiments, the first and second surfaces may be adjacent or spatially intersecting (typically, spatially perpendicular). For example, the male connector 3 protrudes outward from the left side surface (first surface) of the outer casing 1, while the female connector 4 protrudes relative to the upper side surface (second surface) of the outer casing 1.

[0037] Male connector 3 and female connector 4 can be the same or different. Male connector 3 or female connector 4 may include a USB Type-A interface, a USB Type-B interface, a USB Type-C interface, an HDMI interface, or an RJ45 interface. In the example shown in the attached diagram, one of male connector 3 and female connector 4 is an RJ45 interface and the other is a USB Type-C interface, thus the adapter specifically enables LAN and USB switching, allowing devices to connect to a network.

[0038] In this embodiment, a common-mode choke element 5 and an electrostatic discharge protection element 6 are installed on the printed circuit board 2 inside the adapter, and are electrically connected to the signal lines on the printed circuit board 2 respectively. In addition to the adapter function, it also has the effect of preventing EMI / ESD, which can effectively filter out electromagnetic interference and electrostatic discharge effects, and avoid noise and static electricity affecting the product. The male connector 3 and the female connector 4 are connected to the same printed circuit board 2, and are directly electrically connected through the signal lines on the printed circuit board 2, which helps to make the adapter structure compact, reduce its size, and eliminate the need for additional connecting cables.
