[0023] Reference below Figures 1 to 9 A method for manufacturing a connector according to an embodiment of the first aspect of the present invention is described in detail.

[0024] refer to Figure 1A method for manufacturing a connector according to a first embodiment of the present invention includes the following steps: S100, soldering one end of the connection terminal 200 to the first soldering pad 310 on one end of the PCB 300; S200. Wrap the connecting terminal 200 and the PCB300 through the wrapping structure 100 to form a connector, wherein the connector has a first connecting end and a second connecting end relative to each other, the other end of the connecting terminal 200 extends to the first connecting end and is used to be electrically connected to the first electrical connection structure, the other end of the PCB300 extends to the second connecting end, and the other end of the PCB300 is provided with a second soldering pad 320 for being electrically connected to the second electrical connection structure, and the second soldering pad 320 is electrically connected to the first soldering pad 310.

[0025] During the manufacturing process using the manufacturing method of the present application, one end of the connecting terminal 200 is first welded to the first solder pad 310 on one end of the PCB 300, and then the connecting terminal 200 and the PCB 300 are wrapped by the wrapping structure 100 to form a connector. The connector manufactured using the manufacturing method of the present application is connected to the second electrical connection structure via the second solder pad 320 at one end of the PCB 300. The signal is transmitted to the first solder pad 310 through the PCB 300 board, and then transmitted to the first electrical connection structure through the connecting terminal 200 welded to the first solder pad 310. This effectively reduces the possibility of poor contact between the connector and the second electrical connection structure. Therefore, the signal transmission of the connector manufactured using the manufacturing method of the present application is more stable.

[0026] refer to Figure 2 In some embodiments of the present invention, one end of the PCB 300 is provided with a plurality of first solder pads 310 distributed at intervals, and the other end of the PCB 300 is provided with a plurality of second solder pads 320, and the second solder pads 320 correspond to the first solder pads 310 one by one and are electrically connected; S100 specifically includes the following steps: S110, distributing a plurality of connection terminals 200 in parallel and at intervals along a preset direction; S120 , soldering one end of each connection terminal 200 to each first soldering pad 310 .

[0027] It can be understood that by distributing multiple connecting terminals 200 in parallel at intervals along a preset direction, and then welding one end of each connecting terminal 200 to each first solder pad 310 of PCB300, the transmission efficiency of the connector manufactured by the manufacturing method of the present application is higher.

[0028] like Figure 3 As shown, in some embodiments, S110 specifically includes the following steps: S111, placing a plurality of connection terminals 200 spaced apart and side by side in a preset direction in a first injection mold; S112 , forming a first plastic core 400 by injection molding in a first injection mold, so that the first plastic core 400 wraps and fixes each connecting terminal 200 .

[0029] It can be understood that the connecting terminals 200 are first placed side by side in a preset direction in a first injection mold, and then injection molded in the first injection mold to form a first glue core 400, so that the first glue core 400 wraps and fixes each connecting terminal 200, and then the first glue core 400 is aligned with the PCB300, so that each connecting terminal 200 can be aligned with each first soldering pad 310, which facilitates welding each connecting terminal 200 with each first soldering pad 310. The manufacturing method of the present application reduces the difficulty of manufacturing the connector and improves manufacturing efficiency.

[0030] It is understandable that the manufacturing method of the present application has lower requirements on the structure of the connection terminal 200, making the structure of the connection terminal 200 simpler, thereby reducing the material flow resistance during the injection molding process and avoiding molding defects.

[0031] In some embodiments, second solder pads 320 are provided on both the front and back surfaces of the PCB 300. It is understood that by providing first solder pads 310 on both the front and back surfaces of the PCB 300, the first electrical connection structure can simultaneously transmit signals through the first solder pads 310 on both the front and back surfaces of the PCB 300, thereby improving the signal transmission efficiency of the connector. Furthermore, because the present application uses the PCB 300 as the tongue portion for connection to the second electrical connection structure, the structure is relatively simple, and therefore the manufacturing method of the present application is more convenient.

[0032] refer to Figure 4 In some embodiments of the present invention, the packaging structure 100 includes a second plastic core 110 and a shielding shell 120, and S200 includes the following steps: S220 , wrapping the connection terminal 200 and the PCB 300 with the second rubber core 110 to completely cover the junction between the PCB 300 and the connection terminal 200 ; S230 , installing the second rubber core 110 in the accommodating cavity 120 a of the shielding shell 120 to form a connector.

[0033] It can be understood that the second glue core 110 wraps the connecting terminal 200 and the PCB 300, and completely covers the junction of the PCB 300 and the connecting terminal 200, so as to achieve further fixation and protection of the connecting terminal 200 and the PCB 300, and reduce the possibility of the connecting terminal 200 being separated from the first pad 310 of the PCB 300, and then the second glue core 110 is installed in the accommodating cavity 120a of the shielding shell 120, so as to further protect the PCB 300 and the connecting terminal 200.

[0034] As shown in Figure 4 In some embodiments, the wrapping structure 100 further includes a limiting glue core 130, and before S220, the following steps are further included: S210, wrapping the structure of the PCB 300 between the first pad 310 and the second pad 320 by the limiting glue core 130.

[0035] It can be understood that when the connector manufactured by the manufacturing method of the present application is inserted into the shielding shell 120, the limiting glue core 130 can limit the length of the second electrical connection structure extending into the shielding shell 120, so as to achieve protection of the connector.

[0036] It can be understood that the structure of the PCB 300 between the first pad 310 and the second pad 320 is first wrapped by the limiting glue core 130, and then the connecting terminal 200 and the PCB 300 are wrapped by the second glue core 110, so as to fix the position of the limiting glue core 130 on the PCB 300, and reduce the possibility of the limiting glue core 130 loosening during multiple uses of the connector.

[0037] As shown in Figure 5 In some embodiments, the limiting glue core 130 includes a first limiting piece 131 and a second limiting piece 132 connected detachably, and S210 specifically includes the following steps: S211, placing the PCB 300 between the first limiting piece 131 and the second limiting piece 132; S212, connecting the first limiting piece 131 and the second limiting piece 132 to form the limiting glue core 130, and wrapping the structure of the PCB 300 between the first pad 310 and the second pad 320 by the limiting glue core 130.

[0038] It is understandable that the PCB 300 is first placed between the first limiting member 131 and the second limiting member 132, and then the first limiting member 131 and the second limiting member 132 are connected to form the limiting rubber core 130. At this time, the limiting rubber core 130 can wrap the structure of the PCB 300 located between the first solder pad 310 and the second solder pad 320, and then the connecting terminal 200 and the PCB 300 are wrapped by the second rubber core 110. The manufacturing method of the present application divides the limiting rubber core 130 into the first limiting member 131 and the second limiting member 132, so that the first limiting member 131 and the second limiting member 132 of the limiting rubber core 130 can be manufactured separately, thereby reducing the difficulty of connector manufacturing and facilitating the subsequent assembly of the limiting rubber core 130 and the PCB 300.

[0039] In one embodiment, the first limiting member 131 and the second limiting member 132 have the same structure. Both the first limiting member 131 and the second limiting member 132 are provided with an insertion portion 131a and an insertion hole 132a. Connecting the first limiting member 131 and the second limiting member 132 includes the following steps: The insertion portion 131 a of the first limiting member 131 is inserted into the insertion hole 132 a of the second limiting member 132 , and the insertion portion 131 a of the second limiting member 132 is inserted into the insertion hole 132 a of the first limiting member 131 .

[0040] It can be understood that the connection between the first limiting member 131 and the second limiting member 132 is achieved by passing the through hole 132a of the first limiting member 131 through the through hole 132a of the second limiting member 132, and passing the through portion of the second limiting member 132 through the through hole of the first limiting member 131. This connection form is relatively simple and reduces the difficulty of manufacturing the connector.

[0041] like Figure 6 As shown, in some embodiments, S220 specifically includes the following steps: S221, placing the connected connection terminal 200 and PCB 300 in a second injection mold simultaneously; S222 , forming a second plastic core 110 by injection molding in a second injection mold, so that the second plastic core 110 completely covers the junction between the PCB 300 and the connecting terminal 200 .

[0042] It is understandable that the welded connection terminal 200 and PCB 300 are placed in a second injection mold, and then injection molded in the second injection mold to form the second plastic core 110. The injection molding process is relatively simple, which reduces the manufacturing difficulty of the present application.

[0043] Reference below Figures 7 to 9 A connector according to an embodiment of the second aspect of the present invention is described in detail.

[0044] According to a second embodiment of the present invention, a connector is manufactured using the manufacturing method of the first embodiment described above. In the connector manufactured using the manufacturing method of the present application, PCB 300 can function as a tongue to contact the second electrical connection structure for signal transmission, effectively reducing the possibility of poor contact between the connector and the second electrical connection structure, thereby making the signal transmission of the connector of the present application more stable.

[0045] refer to Figures 7 to 9 A connector according to an embodiment of the first aspect of the present invention includes a wrapping structure 100, a connecting terminal 200 and a PCB 300, wherein a plurality of connecting terminals 200 are arranged side by side and spaced apart, the connecting terminal 200 is passed through the wrapping structure 100, and one end of the connecting terminal 200 is used to be electrically connected to the first electrical connection structure; the PCB 300 is passed through the wrapping structure 100, and a plurality of first soldering pads 310 are provided on one end of the PCB 300, and the first soldering pads 310 are used to be electrically connected to the second electrical connection structure, and a plurality of second soldering pads 320 corresponding to and electrically connected to the first soldering pads 310 are provided at the other end opposite to the PCB 300, and the second soldering pads 320 are arranged in a one-to-one correspondence with the connecting terminal 200, and the second soldering pads 320 are welded to the other end of the corresponding connecting terminal 200.

[0046] In the connector of the present application, one end of a plurality of connection terminals 200 is connected to a first electrical connection structure, and the other ends of the plurality of connection terminals 200 are respectively soldered to corresponding second solder pads 320 on a PCB 300. When the second electrical connection structure is connected to the first solder pad 310, the first solder pad 310 transmits the signal to the second solder pad 320 through the circuit of the PCB 300, thereby transmitting the signal to the first electrical connection structure via the connection terminals 200 connected to the second solder pad 320. In the present application, by soldering the PCB 300 to the connection terminals 200, the PCB 300 can act as a tongue to contact the second electrical connection structure for signal transmission, effectively reducing the possibility of poor contact between the connector and the second electrical connection structure, thereby making the signal transmission of the connector of the present application more stable.

[0047] refer to Figure 8 and Figure 9 In some embodiments of the present invention, first solder pads 310 are provided on both the front and back surfaces of the PCB 300. It is understood that by providing first solder pads 310 on both the front and back surfaces of the PCB 300, the first electrical connection structure can simultaneously transmit signals through the first solder pads 310 on both the front and back surfaces of the PCB 300, thereby improving the signal transmission efficiency of the connector. Furthermore, because the present application uses the PCB 300 as the tongue portion for connection to the second electrical connection structure, the structure is relatively simple, and the connector assembly and manufacturing process is more convenient.

[0048] refer to Figure 7 and Figure 8 In some embodiments of the present invention, the connector also includes a first rubber core 400, the wrapping structure 100 includes a second rubber core 110 and a shielding shell 120, the first rubber core 400 wraps the connecting terminal 200, the second rubber core 110 wraps the PCB 300, and the shielding shell 120 wraps the first rubber core 400 and the second rubber core 110. It can be understood that the connector of the present application first forms a first rubber core 400 by injection molding on the connecting terminal 200, so that the first rubber core 400 wraps a plurality of connecting terminals 200 arranged side by side and spaced apart, thereby achieving the fixation of the plurality of connecting terminals 200, so as to facilitate the subsequent connection of the connecting terminals 200 with the PCB300. After the plurality of connecting terminals 200 are welded to the PCB300, injection molding is performed again to make the second rubber core 110 wrap the PCB300, and the second rubber core 110 wraps the area where the PCB300 and the connecting terminal 200 intersect, thereby making the connection between the connecting terminal 200 and the PCB300 more secure. By injection molding in multiple times, the difficulty of the wrapping structure 100 wrapping the connecting terminal 200 and the PCB300 is reduced.

[0049] like Figure 9 As shown, in some embodiments, a positioning hole 330 is provided on the PCB 300, and a positioning post 410 is provided on the first plastic core 400, and the positioning post 410 is passed through the positioning hole 330. It can be understood that by passing the positioning post 410 on the first plastic core 400 through the positioning hole 330 on the PCB 300, the first plastic core 400 is positioned on the PCB 300, so that each connecting terminal 200 of the first plastic core 400 can be aligned with the second soldering pad 320 on the PCB 300, thereby facilitating soldering each connecting terminal 200 to each second soldering pad 320.

[0050] like Figure 8 and Figure 9 As shown, in some embodiments, the wrapping structure 100 further includes a limiting rubber core 130. A mounting channel is defined within the limiting rubber core 130, through which the PCB 300 passes. The limiting rubber core 130 is located between the first solder pad 310 and the second solder pad 320, and is at least partially contained within the second rubber core 110. It will be appreciated that by providing the limiting rubber core 130 between the first solder pad 310 and the second solder pad 320, when the second electrical connection structure is subsequently inserted into the shielding shell 120, the limiting rubber core 130 can limit the length of the second electrical connection structure extending into the shielding shell 120, thereby protecting the connector.

[0051] like Figure 9As shown, in some embodiments, the limiting rubber core 130 includes a first limiting member 131 and a second limiting member 132 that are detachably connected, with a mounting channel defined between the first limiting member 131 and the second limiting member 132. It will be appreciated that by making the first limiting member 131 and the second limiting member 132 detachable and the PCB 300 passing through the mounting channel between the first limiting member 131 and the second limiting member 132, the limiting rubber core 130 can be manufactured separately, thereby reducing the difficulty of connector manufacturing and facilitating subsequent assembly of the limiting rubber core 130 and the PCB 300.

[0052] like Figure 9 As shown, in one embodiment, the first limiting member 131 and the second limiting member 132 have the same structure, and the first limiting member 131 and the second limiting member 132 are both provided with an insertion portion 131a and an insertion hole 132a. The insertion portion 131a of the first limiting member 131 is inserted into the insertion hole 132a of the second limiting member 132, and the insertion portion of the second limiting member 132 is inserted into the insertion hole of the first limiting member 131. It can be understood that by passing the through hole 132a of the first limiting member 131 through the through hole 132a of the second limiting member 132, and passing the through portion of the second limiting member 132 through the through hole of the first limiting member 131, the connection between the first limiting member 131 and the second limiting member 132 is achieved, and the structure is relatively simple and the manufacturing is more convenient; and since the first limiting member 131 and the second limiting member 132 have the same structure, the first limiting member 131 and the second limiting member 132 can be formed by injection molding using the same mold, which reduces the number of mold openings and simplifies the manufacturing process of the limiting rubber core 130.

[0053] like Figure 8 As shown, in some embodiments, a limiting groove 111 is provided on the second rubber core 110, and a limiting block 121 is provided on the shielding shell 120. The limiting block 121 is disposed in the limiting groove 111 and is used to prevent the shielding shell 120 from moving relative to the second rubber core 110. It can be understood that by providing the limiting groove 111 on the second rubber core 110 and the limiting block 121 on the shielding shell 120, the cooperation between the limiting block 121 and the limiting groove 111 can make the connection between the shielding shell 120 and the second rubber core 110 more secure, thereby reducing the possibility of the shielding shell 120 automatically separating from the second rubber core 110 under the action of external force.

[0054] refer to Figure 8In some embodiments of the present invention, an elastic structure 122 is provided on the shielding shell 120. The elastic structure 122 is used to provide an elastic force to maintain the second electrical connection structure in contact with the first pad 310. It will be understood that by providing the elastic structure 122 on the shielding shell 120, when the second electrical connection structure is inserted into the shielding shell 120 and connected to the first pad 310 of the PCB 300, the elastic structure 122 can provide the second electrical connection structure with an elastic force to maintain the second electrical connection structure in contact with the first pad 310, thereby making signal transmission between the second electrical connection structure and the first electrical connection structure more stable.

[0055] Specifically, the elastic structure 122 is an elastic sheet, and the elastic sheet and the shielding shell 120 are integrally formed.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
