The portion of the first terminal module 1 extending out of the terminal housing 3 forms N first pins 13, and the portion of the second terminal module 2 extending out of the terminal housing 3 forms N second pins 22. The N first pins 13 and N second pins 22 are arranged in an array to form a connection terminal for insertion into a PCB board 4, wherein N≥3.

[0056] As an example, refer to Figure 5 It is known that most Type-C connectors on the market are surface-mount, and the connection between the terminal module and the PCB board is achieved through solder paste application and reflow soldering.

The first terminal module 1 and the second terminal module 2 are matched to form a complete Type-C connector. The terminal housing 3 is injection molded onto the stack... The first terminal module 1 and the second terminal module 2 are placed on the PCB board 4. The portion of the first terminal module 1 extending out of the terminal housing 3 forms N first pins 13, and the portion of the second terminal module 2 extending out of the terminal housing 3 forms N second pins 22. The N first pins 13 and the N second pins 22 are arranged in an array to form a connecting terminal for insertion onto the PCB board 4. This installation method, which directly inserts the Type-C connectors formed by the first terminal module 1 and the second terminal module 2 onto the PCB board 4 through the connecting terminal, is simpler and more convenient than the surface mount method. It can shorten the product manufacturing process and the assembly line can be shortened accordingly. At the same time, it can reduce the amount of PCB board 4 used, thereby achieving the effect of saving resources.

N first pins 13 and N second pins 22 are arranged in an array to form a connection terminal for plugging into the PCB board 4. This installation method, which directly plugs the Type-C connector formed by the first terminal module 1 and the second terminal module 2 into the PCB board 4 through the connection terminal, is simpler and more convenient than the surface mount method. It can shorten the product manufacturing process and the assembly line can be shortened accordingly. At the same time, it can reduce the amount of PCB board 4 used, thereby achieving the effect of saving resources.

[0061] In one embodiment, reference is made to Figure 1The first conductive lead 111 includes a first connecting portion 1111, a first bending portion 1112, and a second connecting portion 1113. The first connecting portions 1111 of the N first conductive leads 111 are threaded onto the middle clamping piece 12.

The second injection molded part 142 is injection molded onto a portion of the second connecting portions 1113 of the N first conductive leads 111 near the first bending portion 1112, such that the second connecting portions 1113 extend beyond the portion of the second injection molded part 142. The second conductive lead 211 forms N first pins 13; the second conductive lead 211 includes a third connecting portion 2111, a second bending portion 2112 and a fourth connecting portion 2113; the second module housing 23 includes a third injection molded part 231 and a fourth injection molded part 232, the third injection molded part 231 is injection molded on the portion of the third connecting portion 2111 of the N second conductive leads 2111 near the second bending portion 2112, and the fourth injection molded part 232 is injection molded on the portion of the fourth connecting portion 2113 of the N second conductive leads 2111 near the second bending portion 2112, such that the fourth connecting portion 2113 extends out of the portion of the fourth injection molded part 232 to form N second pins 22.

[0062] As an example, a first conductive lead 111 is described, comprising a first connecting portion 1111, a first bending portion 1112, and a second connecting portion 1113. The first connecting portions 1111 of N first conductive leads 111 are threaded onto a central clamping piece 12 to form an assembly. The first module housing 14 comprises a first injection molded part 141 and a second injection molded part 142. The first injection molded part 141 is injection molded onto all the first connecting portions 1111 of the N first conductive leads 111 and onto the central clamping piece 12. The second injection molded part 142... The plastic part 142 is injection molded on the second connection portion 1113 of N first conductive leads 111, near the first bending portion 1112. The first injection molded part 141 and the second injection molded part 142 are bent and stripped based on the first bending portion 1112 to form the first terminal module 1 of the required shape. The second connection portion 1113 extends out of the second injection molded part 142 to form N first pins 13. The N first pins 13 of the first terminal module 1 are inserted into the PCB board 4. The second conductive lead 211 includes a third connecting portion 2111, a second bending portion 2112, and a fourth connecting portion 2113; the second module housing 23 includes a third injection molded part 231 and a fourth injection molded part 232. The third injection molded part 231 is injection molded on the portion of the third connecting portion 2111 of the N second conductive leads 2111 near the second bending portion 2112. The fourth injection molded part 232 is injection molded on the portion of the fourth connecting portion 2113 of the N second conductive leads 2111 near the second bending portion 2112. The third injection molded part 231 and the fourth injection molded part 232 are bent and stripped based on the second bending portion 2112 to form the second terminal module 2 of the required shape. The fourth connecting portion 2113 extends out of the portion of the fourth injection molded part 232 to form N second pins 22. The N second pins 22 of the second terminal module 2 are inserted into the PCB board 4.

[0063] In one embodiment, reference is made to Figure 1 The connection terminal includes a Type-C10 terminal, with N first pins 13 and N second pins 22 including a grouped differential signal pin, a USB positive pin, a USB negative pin, a power positive pin, and a ground pin; or, the connection terminal includes a Type-C6 terminal, with N first pins 13 and N second pins 22 including a grouped differential signal pin, a power positive pin, and a ground pin.

[0064] As an example, currently available Type-C connectors are all 16- or 24-pin surface-mount type, used in terminal chargers. They are typically reflow soldered after applying solder paste, and the PCB board (4) is usually a multi-layer board. (See reference...) Figure 4From this, we can understand the function of the 24-terminal connector. Among them, A2, A3, A10, A11 / B2, B3, B10, and B11 are used for high-speed transmission, commonly referred to as 20G / 40G, which relies on these terminal pairs for transmission. They are useless for the charger. Therefore, if the charger uses a 24-terminal surface-mount Type-C connector, the 14 terminals A1, A2, A3, A4, A8, A10, A11 / B1, B2, B3, B4, B8, B10, and B11 are redundant and useless. If the charger uses a 16-terminal surface-mount Type-C connector, 6 terminals are redundant and useless. The connection terminals in this example include a Type-C10 terminal, N first pins 13 and N second pins 22, including grouped differential signal pins, USB positive pins, USB negative pins, power positive pins and ground pins; it can meet the functions of fast charging and identification terminals of the charger, that is, it perfectly replaces USB 2.0, meets all the functions of the charger, responds to EU standard requirements, improves production efficiency and product quality.

[0065] The connection terminals in this example also include a Type-C6 terminal. N first pins 13 and N second pins 22 include grouped differential signal pins, a positive power pin, and a ground pin. The Type-C6 terminal has four fewer pins than the Type-C10 terminal, but this is to accommodate chargers with low current requirements. This provides users with more options and is more cost-effective than the Type-C10 terminal. Furthermore, this product occupies less PCBA space, making better use of PCB space, resulting in a smaller overall product size.

[0066] In this example, the Type-C connector is plugged into the single-sided PCB board 4 and fixed by ordinary wave soldering. This meets the requirements of fast charging and data transfer, reduces the number of Type-C connectors, improves production efficiency, and allows the depth of the connector plugged into the PCB board 4 to be adjusted according to customer requirements. Centering the connector makes the appearance more aesthetically pleasing and improves product quality. It can also replace the existing 2.0 USB, making the charger more beautiful and compact, and saving limited resources.

[0067] This invention provides a method for manufacturing a Type-C connector, referring to... Figure 1 and Figure 4 ,include:

[0068] S11: Injection molding is performed on the first terminal element 11 and the middle clip 12 to obtain the first terminal module 1;

[0069] S12: Injection molding is performed on the second terminal element 21 to obtain the second terminal module 2;

[0070] S13: The stacked first terminal module 1 and second terminal module 2 are injection molded to obtain the terminal housing 3. The portion of the first terminal module 1 extending out of the terminal housing 3 forms N first pins 13, and the portion of the second terminal module 2 extending out of the terminal housing 3 forms N second pins 22. The N first pins 13 and N second pins 22 are arranged in an array to form a connection terminal for insertion into the PCB board 4, wherein N≥3.

[0071] As an example, firstly, the first module housing 14 is injection molded onto a portion of N first conductive leads 111 and the middle clip 12 to form the first terminal module 1. A portion of the N first conductive leads 111 extends out of the first module housing 14 to form N first pins 13. Secondly, the second module housing 23 is injection molded onto a portion of N second conductive leads 211 to form the second terminal module 2. A portion of the N second conductive leads 211 extends out of the second module housing 23 to form N second pins 22. Then, the terminal housing 3 is injection molded onto the stacked first module housing 14 and second module housing 23 to form a Type-C connector. The middle clip 12 separates the N first conductive leads 111 and the N second conductive leads 211. The N first pins 13 and the N second pins 22 are arranged in an array to form a connection terminal for insertion onto the PCB board 4.

[0072] In this example, the connection terminals include either a Type-C 10 terminal or a Type-C 6 terminal. After the Type-C connection terminals are inserted into the single-sided PCB board 4, they are soldered and fixed using ordinary wave soldering. This meets the requirements of fast charging and data transfer for the charger, while reducing the number of Type-C terminals, thus improving production efficiency. Furthermore, the depth of the connection terminals inserted into the PCB board 4 can be adjusted according to customer requirements. Centering the terminals makes the appearance more aesthetically pleasing and improves product quality. It can also replace the existing 2.0 USB, making the charger more aesthetically pleasing and compact, and saving limited resources.

The U-shaped outer shell 52 is provided with a plug pin 51, which is plugged into the PCB board 4.

[0086] As an example, the protective shell 5 includes a U-shaped outer shell 52 and an inner sleeve 53. The inner sleeve 53 is made into a cylindrical sheath by stretching. The inner sleeve 53 is embedded in the U-shaped outer shell 52 by laser welding. The Type-C connector is installed in the U-shaped outer shell 52, and the end of the Type-C connector away from the connecting terminal passes through the inner sleeve 53, which provides good protection for the Type-C connector. In this example, the PCB board 4 is a single-sided board. The connector pin 51 of the protective shell 5 is installed on the PCB board 4 and finally fixed by wave soldering. This plug-in Type-C can adjust the height of the Type-C according to actual needs to meet customer requirements. It is convenient to place the Type-C connector in the center, making the appearance more beautiful and elegant. Moreover, the process is simple and the material cost is low.

[0087] In one embodiment, reference is made to Figure 6 The U-shaped housing 52 includes a first U-shaped plate 521, a second U-shaped plate 522 extending horizontally from one side of the first U-shaped plate 521, and a third U-shaped plate 523 extending horizontally from one side of the second U-shaped plate 522.

The third U-shaped plate 523 is bent relative to the second U-shaped plate 522 to limit the Type-C plug terminal. Plug pins 51 extend from the two support arms of the first U-shaped plate 521 along the opening end of the first U-shaped plate 521.

[0088] As an example, the protective shell 5 includes a first U-shaped plate 521, a second U-shaped plate 522, and a third U-shaped plate 523. The second U-shaped plate 522 extends horizontally from one side of the first U-shaped plate 521, and the third U-shaped plate 523 extends horizontally from one side of the second U-shaped plate 522. The inner sleeve 53 is embedded in the first U-shaped plate 521. The first U-shaped plate 521 and the second U-shaped plate 522 cover the Type-C connector. The third U-shaped plate 523 is bent relative to the second U-shaped plate 522 to limit the Type-C connector and ensure safe and reliable assembly of the equipment. Insertion pins 51 extend from the two support arms of the first U-shaped plate 521 along the opening end of the first U-shaped plate 521. The insertion pins 51 are parallel to the connection terminals of the Type-C connector, which facilitates the insertion of the protective shell 5 onto the PCB board 4 via the insertion pins 51.

[0089] In one embodiment, reference is made to Figure 7 The PCB board 4 is provided with a first mounting hole 41 corresponding to the connection terminal and a second mounting hole 42 corresponding to the plug pin 51; the connection terminal of the Type-C plug terminal is inserted into the first mounting hole 41; the plug pin 51 of the protective shell 5 is inserted into the second mounting hole 42.

The second mounting hole 42 corresponds to the plug pin 51, making it easy to insert the plug pin 51 of the protective shell 5 into the second mounting hole 42. This arrangement makes it easier to insert the Type-C connector and the protective shell 5 onto the PCB board 4. Compared with the surface mount method, it is simpler and more convenient, which can shorten the product manufacturing process and the assembly line can be shortened accordingly. At the same time, it can reduce the amount of PCB board 4 used, thereby achieving the effect of saving resources.

[0091] In this example, the distance from the axial centerline of the Type-C connector to the axis of the upper surface of the PCB board 4 is 5.2~5.3mm. By adjusting the length of the connecting terminal of the Type-C connector in the first mounting hole 41 and the insertion pin 51 of the protective shell 5 in the second mounting hole 42, the distance from the axial centerline of the Type-C connector to the axis of the upper surface of the PCB board 4 can be adjusted to meet customer requirements.

[0092] In one embodiment, reference is made to Figure 2The Type-C connector also includes a waterproof component 6, which includes a waterproof housing 61 and a waterproof ring 62.

The waterproof housing 61 is fitted on the first U-shaped plate 521 and is connected to the waterproof sleeve. The waterproof ring 62 is fitted inside the waterproof housing 61.

[0093] As an example, the waterproof component 6 includes a waterproof housing 61 and a waterproof ring 62. First, a waterproof sleeve is fitted onto the end of the Type-C connector furthest from the connection terminal, so that the waterproof sleeve is connected to the first U-shaped plate 521 to provide waterproof protection for the Type-C connector. The waterproof housing 61 is fitted onto the first U-shaped plate 521 and is connected to the waterproof sleeve. Then, the waterproof ring 62 is fitted inside the waterproof housing 61. This arrangement of the waterproof ring 62 and the waterproof sleeve can prevent liquid from entering the Type-C connector, giving the Type-C connector excellent waterproof performance and improving the service life of the device.

[0094] In this embodiment, refer to Figure 2 , Figure 6 and Figure 7 First, the inner sleeve 53 is embedded in the first U-shaped plate 521 of the U-shaped outer shell 52 to form a protective shell 5; the middle clip is removed to obtain the Type-C connector to be installed; the first U-shaped plate 521 and the second U-shaped plate 522 of the U-shaped outer shell 52 wrap around the Type-C connector to be installed, and the end of the Type-C connector to be installed away from the connecting terminal passes through the inner sleeve 53 to form a Type-C assembly; the third U-shaped plate 523 of the U-shaped outer shell 52 is bent relative to the second U-shaped plate 522 to limit the Type-C connector to be installed; a first mounting hole 41 and a second mounting hole 42 are provided on the PCB board 4; the connecting terminal of the Type-C connector is inserted into the first mounting hole 41; a plug pin 51 is provided on the first U-shaped plate 521 of the protective shell 5; the plug pin 51 of the protective shell 5 is inserted into the second mounting hole 42 to form a Type-C connector.

[0095] In this example, the Type-C connector and the connector pin 51 of the protective shell 5 are inserted into the PCB board 4 and then fixed by wave soldering. This meets the requirements of fast charging and data transfer, reduces the number of Type-C connectors, improves production efficiency, and allows the depth of the connector on the PCB board 4 to be adjusted according to customer requirements. Centering the connector makes the appearance more aesthetically pleasing and improves product quality. It can also replace the existing 2.0 USB, making the charger more beautiful and compact, convenient for users to carry, and greatly enhancing the user experience. It also saves limited resources.

[0096] This invention provides a charger, including a Type-C connector.

[0097] As an example, most Type-C connectors on the market are surface-mount, and the connection between the terminal module and the PCB board is achieved through solder paste application and reflow soldering. Furthermore, the matching PCB board uses a multi-layer design, resulting in high manufacturing costs, complex processes, and reduced production efficiency. In this example, the Type-C connector includes a first terminal module 1, a second terminal module 2, and a terminal housing 3. The first terminal module 1 is injection molded using a first terminal element 11 and a middle clip 12. The second terminal module 2 is injection molded using a second terminal element 21. The first terminal element 11 and the second terminal element 21 serve as the internal metal conductive components of the Type-C connector. The middle clip 12 includes a connecting portion and a strip portion. The connecting portion is positioned between the first terminal element 11 and the second terminal element 21, acting as a separator. The strip portion serves as a handle, providing convenience for users to hold the Type-C connector. The first terminal module 1 and the second terminal module 2 are matched to form a complete Type-C connector. The terminal housing 3 is injection molded onto the stack... The first terminal module 1 and the second terminal module 2 are placed on the PCB board 4. The portion of the first terminal module 1 extending out of the terminal housing 3 forms N first pins 13, and the portion of the second terminal module 2 extending out of the terminal housing 3 forms N second pins 22. The N first pins 13 and the N second pins 22 are arranged in an array to form a connecting terminal for insertion onto the PCB board 4. This installation method, which directly inserts the Type-C connectors formed by the first terminal module 1 and the second terminal module 2 onto the PCB board 4 through the connecting terminal, is simpler and more convenient than the surface mount method. It can shorten the product manufacturing process and the assembly line can be shortened accordingly. At the same time, it can reduce the amount of PCB board 4 used, thereby achieving the effect of saving resources.

[0098] In this example, the Type-C connector includes a Type-C connector, a protective shell 5, and a PCB board 4. The inner sleeve 53 is fitted into the first U-shaped plate 521 of the U-shaped outer shell 52 to form the protective shell 5. The middle clip is removed to obtain the Type-C connector to be installed. The first U-shaped plate 521 and the second U-shaped plate 522 of the U-shaped outer shell 52 enclose the Type-C connector to be installed, with the end of the Type-C connector to be installed, away from the connecting terminal, passing through the inner sleeve 53. A Type-C assembly is formed; the third U-shaped plate 523 of the U-shaped housing 52 is bent relative to the second U-shaped plate 522 to limit the Type-C connector to be installed; a first mounting hole 41 and a second mounting hole 42 are provided on the PCB board 4; the connection terminal of the Type-C connector is inserted into the first mounting hole 41; a plug pin 51 is provided on the first U-shaped plate 521 of the protective housing 5; the plug pin 51 of the protective housing 5 is inserted into the second mounting hole 42 to form a Type-C connector.

[0099] In this example, the Type-C connector and the connector pin 51 of the protective shell 5 are inserted into the PCB board 4 and then fixed by wave soldering. This meets the requirements of fast charging and data transfer, reduces the number of Type-C connectors, improves production efficiency, and allows the depth of the connector on the PCB board 4 to be adjusted according to customer requirements. Centering the connector makes the appearance more aesthetically pleasing and improves product quality. It can also replace the existing 2.0 USB, making the charger more beautiful and compact, convenient for users to carry, and greatly enhancing the user experience. It also saves limited resources.
