[0039] The present invention provides an electronic composite Type-C male connector for charging or transmitting digital video, audio, and other information.

[0040] The electronic composite Type-C male connector proposed by the present invention is a 24PIN full-functional electronic composite Type-C male connector. This structure can also be applied to various special-purpose electronic composite Type-C male connectors with less than 24PIN. This structure can widely support USB3.0, USB3.2, USB4, and future USB transmission protocols with higher speed requirements, and also support various fast charging protocols below 160W.

[0041] In an embodiment of the present invention, as Figures 1 to 6 shown, the electronic composite Type-C male connector includes a protective cover 100, a locking body 200, a plurality of metal terminals 300, and a circuit board assembly 400.

[0042] Specifically, the protective cover 100 is a hollow annular shell. The protective cover 100 is sleeved on the locking body 200. The protective cover 100 is generally made of metal. The metal material has advantages such as high strength compared to plastic materials, and is used to protect the locking body 200 from damage and shield external electromagnetic interference.

[0043] Furthermore, the locking body 200 can be made of plastic or ceramic. The locking body 200 is arranged inside the protective cover 100. A plurality of terminal slots 211 are formed on the locking body 200. The terminal slots 211 are generally square openings and through slots at both ends. One ends of a plurality of metal terminals 300 are respectively inserted into the plurality of terminal slots 211. The locking body 200 is used to protect the plurality of metal terminals 300. In addition, an insertion interface 280 is formed at one end of the locking body 200 for plugging the plug end of the electronic composite Type-C male connector. And a part of the metal terminal 300 is exposed from the terminal slot 211 to the insertion interface 280, facilitating the abutment of the metal terminal 300 with the signal transmission end.

[0044] 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 pads 410 are arranged at intervals on the circuit board assembly 400 (the pad 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 pad 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.

[0045] Considering the requirements of elasticity and rigidity, the metal terminal 300 is made of alloy copper, which can be brass or phosphor bronze.

[0046] In addition, at least part of the circuit board assembly 400 extends into the protective cover 100. It can be that a part of the circuit board assembly 400 extends into the protective cover 100, or the entire circuit board assembly 400 extends into the protective cover 100.

[0047] Electronic components 420 are arranged on the circuit board assembly 400. 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.

[0048] Among them, by arranging the electronic components 420 on the circuit board assembly 400, modulation (converting a digital baseband signal into a digital modulation signal starting from channel transmission) and / or demodulation (restoring the received digital channel signal into a digital baseband signal) of signals can be realized through electronic intervention, so that the signals are transmitted on the circuit board assembly 400 as high-frequency signals.

[0049] The technical solution of the present invention realizes modulation and / or demodulation of signals through electronic intervention by arranging electronic components 420 on the circuit board assembly 400, so that the signals are transmitted on the circuit board assembly 400 as high-frequency signals, isolating the 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 extends into the protective cover 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, and it is easier to obtain the original accurate signal.

[0050] In one embodiment, please refer to Figure 3 and Figure 5 , the circuit board assembly 400 includes two first circuit boards 430 and a second circuit board 440. The two first circuit boards 430 described in the embodiments of the present invention are substantially the same in shape and function, and the two first circuit boards 430 are arranged in parallel.

[0051] It should be noted that 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.

[0052] 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. This setting reduces the material used for the second circuit board 440, saves costs, and reduces the mass of the second circuit board 440, facilitating the carrying or moving of the electronic composite Type-C male connector.

[0053] 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 onto the second circuit board 440.

[0054] In addition, pads 410 are provided on the first circuit board 430. Pads 410 may or may not be provided on the second circuit board 440, and whether to provide pads 410 on the second circuit board 440 is determined according to production requirements.

[0055] In one embodiment, please refer to Figure 2 and Figure 13, the metal terminal 300 has a connection section 310 and an insertion section 320. The connection section 310 and the insertion section 320 can be integrally formed, or the connection section 310 and the insertion section 320 can be welded together. Additionally, the connection section 310 and the insertion section 320 can be connected in a straight line or in a stepped shape. In the embodiment of the present invention, the connection section 310 and the insertion section 320 are connected in a stepped shape. In view of this, the metal terminal 300 abuts against two adjacent sides of the first circuit board 430. The connection section 310 is connected to the first circuit board 430, and the insertion section 320 extends into the terminal slot 211. Therefore, the distance from the insertion section 320 to the connection section 310 is short, that is, the distance for the metal terminal 300 to transmit the received signal to the first circuit board 430 is short.

[0056] In addition, a plurality of auxiliary terminals 800 are further provided between the two first circuit boards 430. The auxiliary terminals 800 can be welded or abutted against the first circuit board 430. The auxiliary terminals 800 are used to fix the connection relationship between the two first circuit boards 430 and make the distance between the two first circuit boards 430 equal.

[0057] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 , the locking body 200 is generally in a ring structure. The locking body 200 is sleeved on the two first circuit boards 430. The locking body 200 can be sleeved on a part of the first circuit board 430 or on the entire first circuit board 430. The locking body 200 is used to protect the first circuit board 430, and the locking body 200 presses the plurality of metal terminals 300 onto the second circuit board 440 through the first circuit board 430 to fix the relative positions of the plurality of metal terminals 300.

[0058] In a preferred embodiment, please refer to Figure 8 , the locking body 200 includes a protective rubber shell 210, a fixing rubber shell 220, and two groups of connecting columns 230 located between the fixing rubber shell 220 and the protective rubber shell 210. The terminal slot 211 is opened on the protective rubber shell 210. The protective rubber shell 210 is used to protect the plurality of connecting terminals. The fixing rubber shell 220 is used to define the relative position of the locking body 200. The number of each group of connecting columns 230 can be one, two, or three. The fixing rubber shell 220, the protective rubber shell 210, and the plurality of connecting columns 230 are integrally formed.

[0059] Specifically, the first circuit board 430 is generally square as a whole and is stepped at some parts. The first circuit board 430 includes a first platform stage 431, a second platform stage 432, and a main body 433. The first platform stage 431, the second platform stage 432, and the main body 433 are integrally formed. The second platform stage 432 has first step surfaces 4321 located on both sides of the first platform stage 431. One ends of the plurality of connecting posts 230 close to the fixed rubber housing 220 abut against the first step surfaces 4321 to limit the relative positions of the plurality of connecting posts 230. The main body 433 has second step surfaces 4331 located on both sides of the second platform stage 432. One side of the fixed rubber housing 220 away from the insertion interface 280 abuts against the second step surfaces 4331 to define the relative position of the locking main body 200.

[0060] In addition, the second circuit board 440 includes a third platform stage 442 and third step surfaces 443 arranged on both sides of the third platform stage 442. The third step surfaces 443 and the first step surfaces 4321 are substantially located in the same plane and are used to define the relative positions of the two groups of the connecting posts 230.

[0061] In one embodiment, please refer to Figure 8 , there are two of the connecting posts 230 in each group, and there are two groups of connecting posts 230, with a total of four connecting posts 230. The connecting posts 230 can be prisms, cylinders, or the connecting posts 230 have both prism surfaces and arc surfaces. The connecting posts 230 in each group are located on one side of the locking main body 200. A through groove 231 is formed between the two connecting posts 230 in each group. A part of the second circuit board 440 extends out of the through groove 231.

[0062] In one embodiment, please refer to Figure 7 , Figure 9 and Figure 11 , the electronic composite Type-C male connector further includes a self-locking elastic piece 500. The self-locking elastic piece 500 is installed on the outer surface of the connecting post 230. The self-locking elastic piece 500 is provided with a first limiting port 510 and a second limiting port 520. The connecting post 230 has a first limiting block 232 that cooperates with the first limiting port 510. The second circuit board 440 has a second limiting block 441 that cooperates with the second limiting port 520 to define the relative positions of the second circuit board 440 and the connecting post 230.

[0063] Specifically, the self-locking elastic piece 500 is provided with a first limiting port 510 and a second limiting port 520. The first limiting port 510 and the second limiting port 520 can be circular ports, square ports, or openings with irregular shapes. A first limiting block 232 that cooperates with the first limiting port 510 is provided on the connecting column 230. The first limiting block 232 can be a circular block, a square block, or a block with an irregular shape, as long as the first limiting block 232 and the first limiting port 510 can be snap-fitted.

[0064] Furthermore, a first limiting port 510 is formed on each self-locking elastic piece 500, and a first limiting block 232 is provided on each connecting column 230. One self-locking elastic piece 500 is snap-fitted with two connecting columns 230. Therefore, at least two first limiting ports 510 are provided on each self-locking elastic piece 500. Of course, the number of first limiting ports 510 on each self-locking elastic piece 500 can be two or four, and the number of first limiting blocks 232 on each connecting column 230 can be one or two.

The second limiting block 441 can be a circular block, a square block, or a block with an irregular shape, as long as it can limit the relative positions of the second circuit board 440 and the connecting column 230.

[0066] In one embodiment, please refer to Figure 7 , Figure 9 and Figure 11 At one end of the self-locking elastic piece 500 away from the first circuit board 430, a hook 530 is provided.
