Description

Technical Field

[0001] The present invention relates to the field of connector products, and particularly to an electronic composite HDMI male connector. Background Art

[0002] High-Definition Multimedia Interface (HDMI for short) is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. HDMI can be used in devices such as set-top boxes, DVD players, personal computers, and televisions. With the continuous development of display technology, the video transmission rate is getting higher and higher. The current transmission rate of HDMI 2.1 has reached 48 Gbps. The performance requirements for connectors for high-speed signal transmission are also getting higher and higher. When transmitting through a connecting cable, due to protocol requirements, 19 core wires are needed. This not only poses a certain difficulty in the process, but also makes the finished cable very thick because of the large number of core wires. The design of the present invention directly composes a PCB board at the connector end, which can not only greatly improve the transmission performance of the connector, but also the compact design can greatly reduce the volume of the traditional connector male welding the PCB board. The design of the present invention is used in electronic composite data cables. On the premise of fully meeting the functional and performance requirements, the number of core wires can be greatly reduced. Normally, only 10 core wires are needed to achieve the effect of the traditional 19 core wires. Moreover, the diameter of the finished cable will also be reduced, making it more convenient to use. The present invention can also be used in fiber optic hybrid data cables. Similarly, it will improve performance, reduce volume, reduce the number of core wires, and thus reduce the diameter of the finished cable. Summary of the Invention

[0040] The present invention provides an electronic composite HDMI male connector for transmitting digital video, audio, and other information.

[0041] The electronic composite HDMI male connector proposed by the present invention is an HDMI-A type composite male connector, and this structure can also be applied to HDMI-C / D type composite male connectors. The HDMI male connector of the present invention can be applicable to the transmission protocols of HDMI 1.3, HDMI 1.4, HDMI 2.0, HDMI 2.1, and future HDMI connectors with higher speed requirements.

[0042] In the embodiments of the present invention, as Figures 1 to 4 shown, the electronic composite HDMI male connector includes a metal housing 100, a protective plastic housing 200, a plurality of metal terminals 300, and a circuit board assembly 400.

[0043] Specifically, the metal housing 100 is a hollow annular housing. The metal housing 100 is sleeved on the protective plastic housing 200. The metal housing 100 is generally made of stainless steel. The metal housing 100 has advantages such as high strength compared to a plastic housing, and is used to protect the protective plastic housing 200 and other components from damage, as well as to shield external electromagnetic interference.

[0044] Furthermore, the protective plastic housing 200 is made of plastic. The protective plastic housing 200 is disposed within the metal housing 100. A plurality of terminal slots 210 are formed on the protective plastic housing 200. The terminal slots 210 are generally through slots with a square opening. One ends of the plurality of metal terminals 300 are respectively inserted into the plurality of terminal slots 210. In addition, an insertion interface is formed at one end of the protective plastic housing 200 to facilitate the insertion of the female socket and the HDMI male connector. And a part of the metal terminal 300 is exposed from the terminal slot 210 to the insertion interface to facilitate the abutment of the metal terminal 300 with the signal transmission end.

[0045] Among them, there are multiple circuit boards in the circuit board assembly 400. The number of circuit boards can be two or three. A plurality of spaced pads 410 are provided on the circuit board assembly 400 (the pads 410 can be made of pure copper, and the high-frequency characteristics and electrical conductivity of copper are much better than those of alloy copper. In view of this, it is better to transmit signals through the pads 410). The other ends of the plurality of metal terminals 300 are respectively connected to the plurality of pads 410 in a one-to-one correspondence. The connection method can be welding or abutting. The number of pads 410 on the circuit board assembly 400 can be the same as or different from the number of metal terminals 300, and the positions of the pads 410 and the distances between the pads 410 can be changed according to different production requirements during production.

[0046] Considering the requirements for elasticity and rigidity, the metal terminals 300 are made of alloy copper, which can be brass or phosphor bronze.

[0047] In addition, at least a part of the circuit board assembly 400 extends into the metal housing 100. It can be that a part of the circuit board assembly 400 extends into the metal housing 100, or the entire circuit board assembly 400 extends into the metal housing 100.

[0048] Electronic components 420 are provided on the circuit board assembly 400. The electronic components 420 are connected to the plurality of pads 410. The number of the electronic components 420 can be one, two, or more. The electronic components 420 can be electronic elements, electronic devices, or both electronic elements and electronic devices. The electronic elements can be resistors, capacitors, or filters; the electronic components 420 can be diodes, triodes, or integrated circuits.

[0049] Among them, by providing the electronic components 420 on the circuit board assembly 400, signal modulation (converting the digital baseband signal into a digital modulation signal suitable for channel transmission) and / or demodulation (restoring the received digital channel signal into a digital baseband signal) can be achieved through electronic intervention, so that the signal is transmitted as a high-frequency signal on the circuit board assembly 400.

[0050] The technical solution of the present invention realizes modulation and / or demodulation of signals in an electronic intervention manner by arranging electronic components 420 on the circuit board assembly 400, enabling signals to be transmitted at high frequencies on the circuit board assembly 400, isolating electromagnetic interference between signals from each other, so that the attenuation, distortion, and error code of the transmitted signals passing through the connector are less. And at least part of the circuit board assembly 400 is extended into the metal housing 100, thereby reducing the length of the metal terminals 300, reducing the equivalent resistance between the metal terminals 300, reducing signal attenuation, and also having less signal distortion and error code, making it easier to obtain the original accurate signals.

[0051] In one embodiment, please refer to Figures 3 to 4 , the circuit board assembly 400 includes two first circuit boards 430 and a second circuit board 440. The two first circuit boards 430 in the embodiment of the present invention have substantially the same shape and function, and the two first circuit boards 430 are arranged in parallel. One of the first circuit boards 430 may be provided with a chamfer, and the chamfer is provided to avoid other accessories that cooperate with the HDMI male connector; of course, the first circuit board 430 may also not be provided with a chamfer.

[0052] The electronic components 420 are arranged on the two first circuit boards 430, and the electronic components 420 include diodes and filters. It may be that the electronic components 420 only include diodes and filters, or it may be that the electronic components 420, in addition to including diodes and filters, also include other electronic elements and / or electronic devices. During the demodulation process, the signal passes through the detection diode and then through the filter to obtain the original analog signal. Two first circuit boards 430 are provided, and the length of the first circuit board 430 is set to be longer, so that the first circuit board 430 has more space to facilitate the installation of the electronic components 420 to meet different production requirements.

[0053] Among them, the length of the second circuit board 440 is less than that of the first circuit board 430, and the second circuit board 440 is generally arranged in an n shape. Such an arrangement reduces the material used for the second circuit board 440, saves costs, and reduces the mass of the second circuit board 440, thereby reducing the overall mass of the electronic composite HDMI male connector and facilitating the carrying or moving of the electronic composite HDMI male connector.

[0054] The two first circuit boards 430 are respectively arranged on opposite sides of the second circuit board 440, and a plurality of metal terminals 300 are respectively arranged on opposite sides of the second circuit board 440 and are located between the first circuit board 430 and the second circuit board 440, so that the two first circuit boards 430 press the plurality of metal terminals 300 against the second circuit board 440.
