[0019] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0020] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0021] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0022] The embodiment of the present invention provides a connection line for converting HDMI signal to DP signal, such as Figure 1 and Figure 2 As shown, it includes an HDMI connector 100, a DP connector 200, and a cable 300 connecting the HDMI connector 100 and the DP connector 200. The HDMI connector 100 is used to be plugged into the HDMI interface and transmit HDMI signals. The DP connector 200 is used to be plugged into the DP interface and transmit DP signals. The cable 300 is used to transmit the signal at the end of the HDMI connector 100 to the DP connector 200.

[0023] The DP connector 200 includes a housing 210, a DP plug 220 connected to the housing 210, and a circuit board 230 disposed within the housing 210. The housing 210 isolates and protects the DP plug 220 and the circuit board 230. The DP plug 220 is designed to plug into a corresponding DP port. The circuit board 230 is equipped with a conversion circuit 231 and an amplification circuit 232. The conversion circuit 231 converts HDM I signals into DP signals, while the amplification circuit 232 amplifies the input signals. The HDMI connector 100, cable 300, conversion circuit 231, amplification circuit 232, and DP plug 220 are electrically connected in sequence.

[0024] In this embodiment, the HDMI signal is converted and amplified to form a DP signal, which is output by the DP plug 220, which can improve the quality of signal transmission. The line 300 transmits the HDMI signal, so that the line 300 can be made longer, which has the advantage of long signal transmission distance.

[0025] In some embodiments, the conversion circuit 231 may include a conversion chip and its peripheral circuits, and the amplifier circuit 232 may include an amplifier chip and its peripheral circuits. Since both the conversion circuit 231 and the amplifier circuit 232 are already known in the prior art, their specific circuit structures are not described in detail. For example, reference may be made to Chinese Utility Model Patent Publication No. CN205283694U.

[0026] In some embodiments, the shell 210 of the DP connector 200 can be made of plastic. After the wire body 300, the circuit board 230 and the DP plug 220 are connected, the circuit board 230 can be placed in a corresponding mold, and hot-melt plastic can be injected into the mold cavity. After the plastic is molded, the shell 210 that wraps the circuit board 230 and part of the DP plug 220 can be formed.

[0027] In some embodiments, the DP plug 220 includes an inner sleeve 221 and a metal shell 222 that is sleeved on the outside of the inner sleeve 221. The inner sleeve 221 has a socket that is compatible with the DP female head, and the inner sleeve 221 has a built-in connecting wire. The circuit board 230 is fixedly connected to the inner sleeve 221, which facilitates the welding and fixing of the connecting wire of the inner sleeve 221 and the circuit board 230, making wiring more convenient.

[0028] Furthermore, a slot is provided on the end face of the inner sleeve 221 close to the circuit board 230, and the circuit board 230 is inserted into the slot. The slot is used to position the circuit board 230 so that it is in a relatively appropriate position, which facilitates welding and fixing the connecting wires of the inner sleeve 221 to the circuit board 230.

[0029] Furthermore, the slot is filled with glue, which further fixes the circuit board 230 and strengthens the connection strength between the circuit board 230 and the inner sleeve 221.

[0030] In some embodiments, a snap 223 is provided on the surface of the inner sleeve 221, and a snap hole matching the snap 223 is provided on the surface of the metal shell 222. The snap 223 is snapped into the snap hole, which makes it easy to put the metal shell 222 on the outside of the inner sleeve 221, and the snap 223 can limit the metal shell 222 from being separated from the inner sleeve 221, so that the metal shell 222 is stably fixed on the outside of the inner sleeve 221.

[0031] During the overall assembly, the metal shell 222 is first sleeved onto the outer side of the inner sleeve 221 , and then the circuit board 230 is connected to the inner sleeve 221 , and finally the outer shell 210 is formed.

[0032] In some embodiments, a notch 233 is provided at one end of the circuit board 230 close to the wire body 300. The wire body 300 includes multiple core wires 310. Each core wire 310 transmits a corresponding signal. The core wire 310 is routed through the notch 233 so as to be constrained by the side wall of the notch 233. This facilitates that after the outer shell 210 is formed, the outer shell 210 can smoothly wrap all exposed core wires 310.

[0033] Furthermore, the core wire 310 is fixed to the circuit board 230 by welding to be electrically connected to the circuit on the circuit board 230 .

[0034] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
