[0019] For ease of understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. 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 meanings as those commonly understood by those skilled in the art to which this invention belongs. The terms used in this specification and in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0021] See also Figure 1 and Figure 2The connector male head 1 includes a metal shell 10, a mounting part 20 and a terminal assembly. The mounting part 20 is plugged into the metal shell 10, and the terminal assembly is detachably plugged into the mounting part 20. Through the above arrangement, the terminal assembly and the mounting part 20 are not an integral component formed by the injection molding process, but two independent components, which are combined together by an insertion operation. The present application does not need to set the terminal assembly on the mounting part 20 through the injection molding process, but replaces the injection molding process with an assembly operation, thereby avoiding the design of complex molds and reducing costs. Moreover, the assembly operation improves production efficiency compared to the injection molding process. In addition, in the injection molding process, if the terminal assembly or the mounting part 20 is unqualified in production, or the terminal assembly and the mounting part 20 are unqualified as a whole through the injection molding process, the overall structure formed by the terminal assembly and the mounting part 20 will be scrapped, while in the assembly process, only the unqualified parts need to be replaced, and other normal parts can still be assembled, thereby improving the yield rate.

[0022] For the above-mentioned metal housing 10, please refer to Figure 2 The metal shell 10 is provided with an annular through-going installation cavity 11, and the installation cavity 11 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. When the metal housing 10 is plugged into a female connector (not shown), the seal 60 abuts against the inner wall of the female connector to seal the gap between the male and female connectors. The provision of the seal 60 reduces the risk of moisture intrusion through the gap between the male and female connectors, thereby reducing the risk of moisture contact at the electrical connection between the male and female connectors.

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

[0025] Furthermore, the seal 60 includes two annular sealing protrusions 61, which are arranged sequentially along the direction through which the mounting cavity 11 extends. The arrangement of the two sealing protrusions 61 prevents water from entering the housing from being blocked by the two sealing protrusions 61, thereby ensuring a good seal. It will be appreciated that the two sealing protrusions 61 can be integrally formed or formed as two separate components.

[0026] For the above terminal assemblies, see Figure 2 , combined with Figure 3-Figure 5The terminal assembly includes a grounding member 30 and two injection-molded components 40. The injection-molded component 40 includes an insulating carrier 41 and a terminal group 42, and the terminal group 42 is embedded in the insulating carrier 41. The grounding member 30 is clamped between the two injection-molded components 40, and the grounding member 30 is connected to the two injection-molded components 40 respectively. It should be noted that the terminal group 42 is embedded in the insulating carrier 41 through an injection molding process, and the grounding member 30 and the two injection-molded components 40 are assembled. After assembly is completed, the terminal assembly is plugged into the installation space of the mounting member 20.

[0027] It can be understood that a terminal group 42 of the present application is arranged on an insulating carrier 41, which avoids the situation where two terminal groups 42 are arranged 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 component 40, thereby simplifying the mold design in the injection molding process, and replacing the single injection molding process by combining injection molding and assembly, thereby reducing costs.

[0028] The terminal group 42 described above includes several terminals 421 arranged in a sequentially spaced arrangement. Two adjacent terminals 421 are positioned opposite each other, and the two terminal groups 42 are spaced apart from each other. The terminals 421 include a contact portion 421a, a connecting portion 421b, and a soldering portion 421c, which are sequentially connected. The contact portion 421a is used to connect to the female connector, and the soldering portion 421c is partially embedded in the insulating carrier 41. In this embodiment of the present invention, the male connector 1 can be a Type-C male connector.

[0029] The grounding member 30 includes two spring arms 32, one located on either side of the grounding member 30. During insertion of the male connector 1 into the female connector, the two spring arms 32 first contact the two sides of the female connector's tongue. As the male connector 1 is inserted, the two spring arms 32 move away from each other and clamp onto the two sides of the female connector's tongue, thereby reducing the risk of the male connector 1 falling off the female connector.

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

[0031] For the above-mentioned mounting member 20, see Figure 2 , and combined with Figure 6-Figure 8The mounting member 20 is provided with an installation space for detachably inserting the terminal assembly, thereby realizing the assembly of the terminal assembly and the mounting member 20 by plug-in, thereby realizing assembly instead of injection molding.

[0032] In some embodiments, the mounting member 20 includes two opposing side panels 21 that are connected to each other. A clearance groove 29 is provided on both sides of the mounting member 20, connecting the mounting space. The clearance groove 29 is provided between the two side panels 21 and at one end of the mounting member 20 near the welding portion 421c of the terminal 421. The clearance groove 29 is used to avoid the elastic arms 32 from moving away from each other.

[0033] Furthermore, the side plate 21 of the mounting member 20 is provided with a groove 211 at one end near the welding portion 421c of the terminal 421. An insertion portion 414 is provided at one end of the insulating carrier 41 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 member 20 is provided with latches 212 on the sidewalls of both sides of the groove 211. The insulating carrier 41 is provided with latches 411 on both sides of the insertion portion 414, and one latch 411 is latched into one of the latches 212, thereby achieving a detachable connection between the terminal assembly and the mounting member 20. It is understood that the connection method between the mounting member 20 and the terminal assembly is not limited to this. The connection method between the mounting member 20 and the carrier may also be adhesive bonding, riveting, or other latching methods.

[0034] In some embodiments, the mounting member 20 is provided with a plurality of plug-in through-holes 22 and a plurality of receiving grooves 23. The receiving grooves 23 are provided on the inner wall of the side plate 21 of the mounting member 20. The receiving grooves 23 are provided along the direction in which the terminal assembly is inserted into the mounting member 20. The plug-in through-holes 22 and the receiving grooves 23 are both in communication 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 is provided through a plug-in through-hole 22, and 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 of the terminal 421 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 to a limiting portion 421d. The limiting portion 421d of the terminal 421 is plugged into a limiting groove 24. In this way, the arrangement of 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 arrangement of the limiting groove 24 allows the groove walls of the limiting groove 24 to restrict the terminals 421 of the two terminal groups 42 from moving toward each other, thereby reducing interference between the terminals 421 and the tongues (not shown) of the female connector during insertion of the male connector 1 into the female connector, thereby hindering the insertion of the male connector 1. Optionally, the thickness of the limiting portion 421d is less than the thickness of any of the contact portion 421a, the connecting portion 421b, and the welding portion 421c. This reduces the dimension of the limiting groove 24 along the thickness direction of the limiting portion 421d, thereby reducing the difficulty of machining the limiting groove 24.

[0035] Furthermore, the mounting member 20 is provided with a plurality of inspection openings 25 on each of the two side panels 21. The inspection openings 25 extend through the thickness of the side panels 21. Each inspection opening 25 communicates with a stop slot 24, and the stop portion 421d of a terminal 421 is exposed through a inspection opening 25. The inspection openings 25 can be used to detect the absence of a terminal 421 and to verify that each terminal 421 is fully installed.

[0036] In some embodiments, combined with Figure 9 The male connector 1 also includes a shielding member 50. The shielding member 50 includes a shielding plate 51, which serves as a shield. 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. A shielding plate 51 is received in a mounting groove 26, and the shielding plate 51 is lower than the notch of the mounting groove 26. This prevents the portion of the shielding plate 51 protruding from the mounting groove 26 from interfering with 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 includes two first spring clips 52, both of which are arranged obliquely relative to the shielding plate 51. At least a portion of the first spring clips 52 extends out of the mounting slot 26, and the first spring clips 52 abut against the inner wall of the metal housing 10. The connection between the first spring clips 52 and the metal housing 10 electrically connects the metal housing 10 to 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. At the same time, the abutment between the first spring clips 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 a side of the mounting member 20 that is close to the contact portion 421a of the terminal 421, and the first spring piece 52 is disposed on the shielding plate 51 at one end away from the welding portion 421c of the terminal 421. The end of the first spring piece 52 that is close to the welding 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 is a plate-shaped structure, and the first spring piece 52 and the shielding plate 51 are integrally formed.

[0038] The shielding member 50 also includes three second spring clips 53, which are arranged at an angle relative to the shielding plate 51. The first spring clip 52 and the second spring clip 53 are located at opposite ends of the shielding plate 51. Three through-holes 27 are provided on each of the two side panels 21 of the mounting member 20. These through-holes 27 communicate with the mounting space. At least a portion of a second spring clip 53 extends into the mounting space through a through-hole 27. The second spring clip 53 is configured to abut against the tongue of the female connector when the male connector 1 is plugged into the female connector. The second spring clips 53 of the two shielding members 50 clamp the tongue of the female connector. The abutment between the second spring clips 53 and the female connector prevents the male connector 1 from falling off the female connector.

[0039] In some embodiments, both side panels 21 of the mounting member 20 are provided with two snap-fitting grooves 28, and the shielding member 50 also includes two snap-fitting clips 54. The snap-fitting clips 54 and the first spring clips 52 are respectively provided on both sides of the shielding plate 51. The two snap-fitting clips 54 are respectively provided on both sides of the shielding plate 51. A snap-fitting clip 54 is snapped into a snap-fitting groove 28, thereby realizing the connection between the shielding member 50 and the mounting member 20.

[0040] In some embodiments, see Figure 2 The male connector 1 further includes a PCB board 70 , which is disposed at one end of the metal housing 10 close to the soldering portion 421 c of the terminal 421 , and each terminal 421 and the grounding plate are connected to the PCB board 70 .

[0041] In some embodiments, the connector male head 1 also includes a base 80, which is arranged in the mounting cavity 11 of the metal shell 10, and the base 80 is arranged between the terminal assembly PCB board 70. The welding portion 421c of each terminal 421 is partially embedded in the base 80, and the welding portion 421c of each terminal 421 extends out of the base 80 at one end away from the connecting portion 421b and is connected to the PCB board 70.

[0042] In an embodiment of the present invention, the connector male head 1 includes a metal shell 10, a mounting member 20 and a terminal assembly. The metal shell 10 is provided with a mounting cavity 11, and the mounting cavity 11 passes through the metal shell 10. The mounting member 20 is plugged into the mounting cavity 11, and an installation space is provided in the mounting member 20. The terminal assembly includes a grounding member 30 and two injection molding components 40. The injection molding component 40 includes an insulating carrier 41 and a terminal group 42. The terminal group 42 is embedded in the insulating carrier 41, and the grounding member 30 is arranged between the two injection molding components 40. Among them, the terminal assembly can be detachably inserted into the installation space, so the terminal assembly and the mounting member 20 are assembled, which reduces the step of forming the terminal assembly and the mounting member 20 into a whole through the injection molding process. The assembly process is less expensive than the injection molding process, thereby reducing the cost.

[0043] The present invention provides an embodiment of an electronic device, which includes the above-mentioned connector male head 1. The structure and function of the connector male head 1 can be found in the above-mentioned embodiment, and will not be described in detail here.

[0044] The present invention also provides a method for preparing a connector male head 1, which can be referred to as Figure 10 , the preparation method comprises: Step 01, provide terminal assembly.

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

[0046] Step 03: Insert the terminal assembly into the installation space to obtain an assembly. The assembly refers to the assembly of the terminal assembly and the installation member 20. The terminal assembly is inserted and plugged in, replacing the installation member 20 and the terminal assembly formed into a whole through the injection molding process.

[0047] Step 04: Provide a metal housing 10 , wherein the metal housing 10 is provided with a through installation cavity 11 .

[0048] Step 05: Insert the assembly into the mounting cavity 11 to obtain the connector male 1. It is understood that by setting the first preset distance, the assembly is inserted into the mounting cavity 11 and then the insertion of the assembly is stopped to obtain the connector male 1.

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

[0050] In some embodiments, see Figure 11 , step 01 further includes: Step 011 provides two terminal groups 42, two portions of liquid injection molding material, and two molds. The two terminal groups 42 are secured to the two molds, and the two portions of liquid injection molding material are injected into the two molds. The two portions of liquid injection molding material are solidified to obtain two injection-molded components 40. The liquid injection molding material solidifies to form an insulating carrier 41. It should be noted that the two molds are identical, thereby reducing the complexity of the mold design.

[0051] Step 012: Provide a grounding member 30, place it between two injection-molded parts, and secure it to two injection-molded components 40 to form a terminal assembly. By assembling the two injection-molded parts with the grounding member 30, two terminal groups 42 are embedded in the same insulating carrier 41 through a single injection molding process, rather than being embedded in the same insulating carrier 41.

[0052] In some embodiments, the mounting member 20 is provided with a plurality of plug-in through holes 22, and the plurality of plug-in through holes 22 are connected to 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 a limiting groove 24 on the side wall of the receiving groove 23; the terminal group 42 includes a plurality of terminals 421, and the terminal 421 includes a contact portion 421a, a connecting portion 421b and a welding portion 421c connected in sequence. The welding portion 421c is partially embedded in the insulating carrier 41, and the contact portion 421a extends away from the connecting portion 421b at one end thereof. A limiting portion 421d is extended; see Figure 12 , step 03 further includes: In step 031, the contact portion 421a of a terminal 421 is inserted into a receiving groove 23 through a plug-in hole 22, and the limiting portion 421d of a terminal 421 is inserted into a limiting groove 24. The connecting portion 421a of the terminal 421 is inserted into the plug-in hole 22, and the contact portion 421a of the terminal 421 partially protrudes from the receiving groove 23 and extends into the installation space. After passing through the plug-in hole 22, the contact portion 421a moves within the receiving groove 23 until the limiting portion 421d of each terminal 421 is inserted into the corresponding limiting groove 24.
