[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1 and Figure 2The male connector 1 includes a metal housing 10, a mounting component 20, and a terminal assembly. The mounting component 20 is inserted into the metal housing 10, and the terminal assembly is detachably inserted into the mounting component 20. With this configuration, the terminal assembly and the mounting component 20 are not a single integral part formed by injection molding, but rather two independent parts assembled together through a insertion operation. This application eliminates the need for injection molding to install the terminal assembly onto the mounting component 20; instead, it replaces injection molding with an assembly operation, avoiding complex mold design and reducing costs. Furthermore, the assembly operation improves production efficiency compared to injection molding. In addition, during injection molding, if the terminal assembly or mounting component 20 is defective, or if the entire structure formed by the injection molding process is defective, the entire structure of the terminal assembly and mounting component 20 will be scrapped. However, in the assembly process, only the defective parts need to be replaced, while other normal parts can still be assembled, thereby improving the yield rate.

[0022] For the metal casing 10 mentioned above, please refer to... Figure 2 The metal housing 10 is provided with an annular through-hole mounting cavity 11, which is used to accommodate the terminal assembly.

[0023] In some embodiments, the male connector 1 further includes a seal 60, which is disposed on the outer wall of the metal housing 10 and surrounds the metal housing 10. The seal 60 abuts against the inner wall of the female connector (not shown) when the metal housing 10 is inserted into the female connector, sealing the gap between the male connector 1 and the female connector. The seal 60 reduces the risk of moisture entering through the gap between the male connector 1 and the female connector, thereby reducing the risk of moisture contact at the electrical connection between the male connector 1 and the female connector.

[0024] Optionally, the seal 60 is made of silicone. When the metal housing 10 is inserted into the connector female, the thickness of the seal 60 is compressed by 10%-30%. Thus, the seal 60 is compressed between the outer wall of the metal housing 10 and the inner wall of the connector female, thereby achieving a sealing effect.

[0025] Furthermore, the seal 60 includes two annular sealing protrusions 61, arranged sequentially along the through direction of the mounting cavity 11. The arrangement of the two sealing protrusions 61 ensures that moisture entering is blocked sequentially by the two protrusions 61, thereby guaranteeing a sealing effect. It is understood that the two sealing protrusions 61 can be integrally formed or can be two independent components.

[0026] For the terminal assemblies described above, please refer to [link / reference]. Figure 2 , and then combine Figures 3-5The terminal assembly includes a grounding component 30 and two injection-molded components 40. Each injection-molded component 40 includes an insulating carrier 41 and a terminal group 42, with the terminal group 42 embedded in the insulating carrier 41. The grounding component 30 is clamped between the two injection-molded components 40 and connected to each of them. It should be noted that the terminal group 42 is embedded into the insulating carrier 41 through an injection molding process, and the grounding component 30 and the two injection-molded components 40 are assembled. After assembly, the terminal assembly is inserted into the mounting space of the mounting component 20.

[0027] It is understood that in this application, one terminal group 42 is disposed on an insulating carrier 41, which avoids the two terminal groups 42 being disposed on the same insulating carrier 41. That is, the two terminal groups 42 are embedded in the same insulating carrier 41 through the injection molding process, thereby simplifying the structure of the insulating carrier 41 and the injection molding assembly 40, thereby simplifying the mold design in the injection molding process. The injection molding and assembly combination replaces the single injection molding process, reducing costs.

[0028] For the aforementioned terminal group 42, the terminal group 42 includes a plurality of terminals 421 arranged sequentially at intervals, with adjacent terminals 421 arranged opposite to each other, and two terminal groups 42 arranged opposite to each other at intervals. Terminal 421 includes a contact portion 421a, a connecting portion 421b, and a soldering portion 421c connected sequentially. The contact portion 421a is used to connect with the connector female head, and a portion of the soldering portion 421c is embedded in the insulating carrier 41. In this embodiment of the present invention, the connector male head 1 can be a Type-C male head.

[0029] The grounding element 30 includes two spring arms 32, which are located on both sides of the grounding element 30. During the insertion of the male connector 1 into the female connector, the two spring arms 32 first abut against both sides of the tongue of the female connector, and as the male connector 1 is inserted, the two spring arms 32 move away from each other and clamp the two sides of the tongue of the female connector, thereby reducing the risk of the male connector 1 falling off the female connector.

[0030] In some embodiments, an insulating carrier 41 has a positioning post 413 and a positioning groove 412 on the side facing the other insulating carrier 41, and a grounding member 30 has two positioning holes 31. A positioning post 413 passes through a positioning hole 31 and is inserted into a positioning groove 412. This arrangement allows the grounding member 30 and the two injection-molded assemblies 40 to be assembled together, and restricts the movement of the two injection-molded assemblies 40 relative to the grounding member 30, thereby improving the success rate of the assembly of the terminal assembly and the mounting member 20.

[0031] For the aforementioned mounting component 20, please refer to... Figure 2 and combined Figures 6-8The mounting component 20 is provided with a mounting space for the terminal assembly to be detachably inserted, thereby achieving the assembly of the terminal assembly and the mounting component 20 by insertion, thus realizing assembly instead of injection molding.

[0032] In some embodiments, the mounting member 20 includes two opposing side plates 21 connected to each other. Both sides of the mounting member 20 are provided with clearance grooves 29 communicating with the mounting space. The clearance grooves 29 are located between the two side plates 21, and are located at one end of the mounting member 20 near the welding portion 421c of the terminal 421. The clearance grooves 29 are used to avoid the spring arms 32 as they move away from each other.

[0033] Furthermore, the side plate 21 of the mounting component 20 has a groove 211 at one end near the welding portion 421c of the terminal 421, and the insulating carrier 41 has an insertion portion 414 at one end near the contact portion 421a of the terminal 421. The insertion portion 414 is inserted into the groove 211, and the side surface of one insertion portion 414 facing away from the other insertion portion 414 is aligned with the outer surface of the corresponding side plate 21. The mounting component 20 has a latch 212 on the side walls on both sides of the groove 211, and the insulating carrier 41 has a locking platform 411 on both sides of the insertion portion 414. One locking platform 411 is engaged with one latch 212, thus realizing a detachable connection between the terminal assembly and the mounting component 20. It is understood that the connection method between the mounting component 20 and the terminal assembly is not limited to this. The connection method between the mounting component 20 and the carrier can also be bonding, riveting, or other locking methods.

[0034] In some embodiments, the mounting member 20 is provided with a plurality of insertion through holes 22 and a plurality of receiving grooves 23. The receiving grooves 23 are disposed on the inner wall of the side plate 21 of the mounting member 20 and are disposed along the direction in which the terminal assembly is inserted into the mounting member 20. Both the insertion through holes 22 and the receiving grooves 23 communicate with the mounting space. The mounting member 20 is provided with a limiting groove 24 on the side plate 21 of the receiving groove 23. The connecting portion 421b of a terminal 421 passes through a insertion through hole 22. A portion of the contact portion 421a of a terminal 421 is received in a receiving groove 23. The end of the contact portion 421a away from the connecting portion 421b protrudes from the receiving groove 23 and extends into the mounting space. The end of the contact portion 421a away from the connecting portion 421b extends into a limiting portion 421d. The limiting portion 421d of a terminal 421 is inserted into a limiting groove 24. Thus, the receiving groove 23 not only accommodates the contact portion 421a of the terminal 421, but also serves as a guide during the insertion of the terminal assembly into the mounting member 20. The limiting groove 24 restricts the movement of the terminals 421 of the two terminal groups 42 towards each other, thereby reducing interference between the terminal 421 and the tongue (not shown) of the connector female during the insertion of the male connector 1 into the female connector, thus preventing the male connector 1 from being inserted. Optionally, the thickness of the limiting portion 421d is less than the thickness of any one of the contact portion 421a, the connecting portion 421b, and the soldering portion 421c, thereby reducing the dimension of the limiting groove 24 along the thickness direction of the limiting portion 421d and reducing the processing difficulty of the limiting groove 24.

[0035] Furthermore, the mounting component 20 is provided with multiple detection ports 25 on each of the two side plates 21, and the detection ports 25 penetrate the side plates 21 along the thickness direction. One detection port 25 communicates with a limiting groove 24, and the limiting part 421d of a terminal 421 is exposed in one detection port 25. The detection ports 25 can be used to detect whether a terminal 421 is missing, and can also detect whether each terminal 421 is inserted into the preset assembly position.

[0036] In some embodiments, combined with Figure 9 The male connector 1 also includes a shield 50. The shield 50 includes a shielding plate 51, which serves a shielding function. A mounting groove 26 is provided on the outer side of the side plate 21 of the mounting member 20. The mounting groove 26 extends inward from the outer surface of the side plate 21 of the mounting member 20. The shape of the mounting groove 26 matches the shape of the shielding plate 51. One shielding plate 51 is received within one mounting groove 26, and the shielding plate 51 is lower than the opening of the mounting groove 26, thereby preventing interference between the portion of the shielding plate 51 protruding from the mounting groove 26 and the metal housing 10 during the insertion of the mounting member 20 into the metal housing 10. Optionally, the depth of the mounting groove 26 is equal to the thickness of the shielding plate 51.

[0037] Furthermore, the shielding member 50 also includes two first spring contacts 52, both of which are inclined relative to the shielding plate 51. At least a portion of each first spring contact 52 extends out of the mounting groove 26, and the first spring contact 52 abuts against the inner wall of the metal housing 10. The connection between the first spring contact 52 and the metal housing 10 enables an electrical connection between the metal housing 10 and the shielding member 50, thereby grounding the shielding member 50 and the metal housing 10 when the male connector 1 is connected to the female connector 1. Simultaneously, the abutting action between the first spring contact 52 and the metal housing 10 further strengthens the connection between the metal housing 10 and the terminal assembly. Optionally, the shielding member 50 is disposed on the side of the mounting member 20 near the contact portion 421a of the terminal 421. One end of the first spring piece 52 away from the solder portion 421c of the terminal 421 is disposed on the shielding plate 51, and the end of the first spring piece 52 near the solder portion 421c of the terminal 421 abuts against the metal housing 10. This reduces the risk of the first spring piece 52 getting stuck on the inner wall of the metal housing 10 during the insertion of the mounting member 20 into the metal housing 10. Optionally, the first spring piece 52 has a plate-like structure, and the first spring piece 52 is integrally formed with the shielding plate 51.

[0038] Meanwhile, the shielding component 50 also includes three second spring tabs 53, which are inclined to the shielding plate 51, and the first spring tab 52 and the second spring tab 53 are respectively located at both ends of the shielding plate 51. Each of the two side plates 21 of the mounting component 20 is provided with three through holes 27, which connect to the mounting space. At least a portion of one of the second spring tabs 53 extends into the mounting space through one of the through holes 27. The second spring tab 53 is used to abut against the tongue of the connector female when the connector male head 1 is inserted into the connector female head. The second spring tabs 53 of the two shielding components 50 clamp the tongue of the connector female head, and through the abutting action between the second spring tab 53 and the connector female head, it is difficult for the connector male head 1 to detach from the connector female head.

[0039] In some embodiments, the two side plates 21 of the mounting member 20 are each provided with two snap-fit ​​grooves 28, and the shielding member 50 also includes two snap-fit ​​buckles 54. The snap-fit ​​buckles 54 and the first spring piece 52 are respectively provided on both sides of the shielding plate 51. The two snap-fit ​​buckles 54 are respectively provided on both sides of the shielding plate 51, and one snap-fit ​​buckle 54 is snapped into one snap-fit ​​groove 28, thereby realizing the connection between the shielding member 50 and the mounting member 20.

[0040] In some embodiments, please refer to Figure 2 The male connector 1 also includes a PCB board 70, which is disposed at one end of the metal housing 10 near the soldering portion 421c of the terminal 421. Each terminal 421 and the ground plane are connected to the PCB board 70.

[0041] In some embodiments, the male connector 1 further includes a base 80, which is disposed in the mounting cavity 11 of the metal housing 10 and between the terminal assembly PCB boards 70. The soldering portion 421c of each terminal 421 is partially embedded in the base 80, and the end of the soldering portion 421c of each terminal 421 away from the connecting portion 421b extends out of the base 80 and connects to the PCB board 70.

[0042] In this embodiment of the invention, the male connector 1 includes a metal housing 10, a mounting member 20, and a terminal assembly. The metal housing 10 has a mounting cavity 11 that extends through the metal housing 10. The mounting member 20 is inserted into the mounting cavity 11, and a mounting space is provided within the mounting member 20. The terminal assembly includes a grounding member 30 and two injection-molded components 40. Each injection-molded component 40 includes an insulating carrier 41 and a terminal group 42, with the terminal group 42 embedded in the insulating carrier 41. The grounding member 30 is disposed between the two injection-molded components 40. Since the terminal assembly is detachably inserted into the mounting space, the terminal assembly and the mounting member 20 are assembled, reducing the steps required to form a single unit from the injection molding process. Assembly is less expensive than injection molding, thus reducing overall cost.

[0043] This utility model provides an embodiment of an electronic device, which includes the aforementioned male connector 1. The structure and function of the male connector 1 can be found in the above embodiment, and will not be repeated here.

[0044] This utility model also provides a method for manufacturing a male connector 1, please refer to [link / reference]. Figure 10 The preparation methods include: Step 01: Provide terminal assembly.

[0045] Step 02: Provide mounting component 20, wherein mounting component 20 is provided with mounting space. It is understood that mounting component 20 can be obtained by injection molding alone, and mounting component 20 does not need to be formed into a whole with terminal assembly by injection molding, thereby greatly reducing cost.

[0046] Step 03: Insert the terminal assembly into the mounting space to obtain the assembly. The assembly refers to the whole formed by assembling the terminal assembly and the mounting part 20. The insertion and connection of the terminal assembly replaces the injection molding process that forms a whole between the mounting part 20 and the terminal assembly.

[0047] Step 04: Provide a metal housing 10, which has a through mounting cavity 11.

[0048] Step 05: Insert the assembly into the mounting cavity 11 to obtain the male connector 1. It can be understood that by setting a first preset distance, the insertion of the assembly is stopped after the first preset distance is reached, thus obtaining the male connector 1.

[0049] It is understandable that the terminal assembly and the mounting part 20 are detachably connected, and the mounting part 20 is detachably connected to the metal housing 10. The connector male head 1 is obtained through multiple assemblies. During this manufacturing process, if one or more of the terminal assembly, the mounting part 20 and the metal housing 10 have quality problems, they can be replaced with qualified products.

[0050] In some embodiments, please refer to Figure 11 Step 01 further includes: Step 011 involves providing two terminal sets 42, two portions of liquid injection molding material, and two molds. The two terminal sets 42 are fixed to the two molds respectively, and the two portions of liquid injection molding material are injected into the two molds respectively. The two portions of liquid injection molding material are then cured to obtain two injection-molded components 40. The cured liquid injection molding material forms an insulating carrier 41. It should be noted that the two molds are identical, thus reducing the complexity of the mold design.

[0051] Step 012: Provide a grounding component 30, place the grounding component 30 between two injection molded parts, and fix the grounding component 30 to the two injection molded assemblies 40 respectively to obtain a terminal assembly. The assembly of the two injection molded parts with the grounding component 30 replaces the two terminal groups 42 being embedded into the same insulating carrier 41 in a single injection molding.

[0052] In some embodiments, the mounting member 20 is provided with a plurality of insertion through holes 22 communicating with the mounting space. The mounting member 20 is provided with a plurality of receiving grooves 23 on the inner wall of the mounting space, and the mounting member 20 is provided with limiting grooves 24 on the side walls of the receiving grooves 23. The terminal group 42 includes a plurality of terminals 421. Each terminal 421 includes a contact portion 421a, a connecting portion 421b, and a soldering portion 421c connected in sequence. The soldering portion 421c is partially embedded in the insulating carrier 41. The end of the contact portion 421a away from the connecting portion 421b extends to a limiting portion 421d. Please refer to [link to previous document]. Figure 12 Step 03 further includes: Step 031: Insert the contact portion 421a of a terminal 421 into a receiving groove 23 through a insertion hole 22. Insert the limiting portion 421d of a terminal 421 into a limiting groove 24. The connecting portion 421a of a terminal 421 is inserted into the insertion hole 22, and the contact portion 421a of a terminal 421 protrudes from the receiving groove 23 and extends into the installation space. After passing through the insertion hole 22, the contact portion 421a moves within the receiving groove 23 until the limiting portions 421d of each terminal 421 are inserted into the corresponding limiting groove 24. It can be understood that by setting a second preset distance, the terminal assembly can be inserted at a second preset distance, and then insertion can be stopped. At this time, the limiting portion 421d of a terminal 421 is inserted into a limiting groove 24.

[0053] Step 032: Fix the insulating carrier 41 to the mounting part 20 to obtain the assembly.

[0054] In some embodiments, one end of the mounting member 20 is provided with a groove 211, and the mounting member 20 is provided with a slot 212 on the side wall of the groove 211, and the side wall of the insulating carrier 41 is provided with a mounting platform 411. Step 032 further includes: Step 0321: Push the insulating carrier 41 into the groove 211 until the locking platform 411 is engaged with the locking slot 212, thereby fixing the insulating carrier 41 to the mounting part 20 and obtaining the assembly.

[0055] In some embodiments, the mounting component 20 is provided with a plurality of detection ports 25, one detection port 25 communicating with a limiting groove 24. (See also...) Figure 13 After step 03, the preparation method also includes: Step 0351: Check whether the limiting portion 421d of each terminal 421 is aligned along the direction perpendicular to the insertion space of the terminal assembly.

[0056] Step 0352: If yes, then the assembly is deemed qualified.

[0057] Step 0353: If not, then the assembly is determined to be defective.

[0058] In some embodiments, please refer to Figure 14 The mounting component 20 is provided with multiple detection ports 25, one detection port 25 is connected to a limiting groove 24. After step 03, the preparation method further includes: Step 0361: Check whether each detection port 25 exposes the limiting part 421d of terminal 421.
