[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that if directional indications are involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] With the continuous development of information transmission technology, the demand for information transmission speed is increasing, and thus the performance requirements of information transmission connectors are also increasing. This requires not only better materials and higher precision, but also more stringent process guarantees. Therefore, using existing production methods, the difficulty of production has greatly increased production costs and significantly reduced production yields. At the same time, due to the limitations of material properties and production processes, it is still difficult to produce high-performance connectors that fully meet technical standards. The resulting connectors often have a low yield rate and high processing costs.

[0049] In light of this, the present invention proposes a Type-C male connector 100 that addresses any of the technical issues raised above. The Type-C male connector proposed in this invention can be used with standard USB4 cables, as well as various electronic composite cables, such as Thunderbolt 4 cables and fiber-optic Type-C cables. The illustration in this invention shows a Type-C male connector for a USB4 cable.

[0050] See also Figures 3 to 6In one embodiment of the present invention, the type-c male connector 100 includes an insulating sleeve 1, a circuit board 2 and a plurality of metal terminals 3, including a terminal sleeve 11, an upper connecting portion 12 and a lower connecting portion 13, the upper connecting portion 12 and the lower connecting portion 13 are connected so that the terminal sleeve 11 is fixed between the upper connecting portion 12 and the lower connecting portion 13, and a plurality of accommodating grooves 111 are formed on opposite sides of the terminal sleeve 11; the circuit board 2 is installed between the upper connecting portion 12 and the lower connecting portion 13. Between the lower enclosing part 13; multiple metal terminals 3 are electrically connected to the circuit board 2, and multiple metal terminals 3 are at least partially located in the multiple accommodating grooves 111. The bottom of the accommodating groove 111 is provided with a limiting groove 111a, and the metal terminal 3 forms a raised structure 31 toward the limiting groove 111a. The upper enclosing part 12 and the lower enclosing part 13 respectively abut against the raised structures 31 on the opposite sides of the terminal sleeve 11 to limit the relative position of the metal terminal 3 in its extension direction.

[0051] Specifically, the insulating sleeve 1 is used to encase multiple metal terminals 3, securing them and shielding them from interference. This prevents signal interference between the terminals 3. Typically, the insulating sleeve 1 is integrally molded using injection molding. However, the requirements for insulating sleeves 1 suitable for high-speed transmission connectors are high. If an integral molding process is used, the yield rate for high-speed transmission connectors that meet industry standards is low, resulting in high connector manufacturing costs. Therefore, in this embodiment, the insulating sleeve 1 is provided in separate parts, comprising a terminal sleeve 11, an upper connecting portion 12, and a lower connecting portion 13.

[0052] The terminal sleeve 11 is mainly used to accommodate multiple metal terminals 3, so multiple accommodating grooves 111 are provided on opposite sides of the terminal sleeve 11, and multiple metal terminals 3 are respectively accommodated in the multiple accommodating grooves 111. The accommodating grooves 111 can be recessed in the opposite sides of the terminal sleeve 11, but in this embodiment, multiple partitions 113 are provided on the opposite sides of the terminal sleeve 11, and the accommodating grooves 111 are provided between any two adjacent partitions 113, and the accommodating grooves 111 limit the width direction of the metal terminal 3. Furthermore, the wall surface of the partition 113 is provided with a limiting rib protruding toward the accommodating groove 111, and the metal terminal 3 is further limited by the limiting rib, thereby fixing the relative position of the metal terminal 3 to prevent the metal terminal 3 from moving.

[0053] Furthermore, one end of the terminal housing 11 defines a connection cavity 112, which is used to electrically connect the plurality of metal terminals 3 to the circuit board 2 within the female connector, facilitating signal transmission. The accommodating groove 111 is at least partially connected to the connection cavity 112, allowing the metal terminals 3 to be exposed within the connection cavity 112 and to engage the female connector of the male connector.

[0054] Furthermore, the terminal sleeve 11 is primarily used to accommodate multiple metal terminals 3, and securing the multiple metal terminals 3 requires that the upper and lower enveloping portions 12, 13, respectively, form a mating relationship with the terminal sleeve 11. To better position and secure the metal terminals 3, a limiting groove 111a is provided within the accommodating groove 111, allowing the metal terminals 3 to be partially accommodated within the limiting groove 111a. Therefore, a raised structure 31 is formed on the corresponding limiting portion of the metal terminal 3. It should be noted that, in order not to affect the high-speed signal transmission of the metal terminal 3, the thickness of the raised structure 31 is consistent with the thickness of the remaining portion of the metal terminal 3 excluding the raised structure 31. In this embodiment, the raised structure 31 is raised toward the limiting groove 111a, so that the raised structure 31 is substantially in contact with the groove wall of the limiting groove 111a, and the upper and lower enveloping portions 12, 13 are respectively crimped onto the surface of the raised structure 31 on the side away from the limiting groove 111a, thereby crimping the multiple metal terminals 3 into the multiple limiting grooves 111a. This method fixes the metal terminals 3 and limits the metal terminals 3 in their extension direction, thereby replacing the integrally molded plastic sheath, reducing the difficulty of molding the plastic sheath, improving the yield rate of the high-speed signal transmission connector, and reducing the manufacturing cost of the Type-C male connector 100.

[0055] The technical solution of the present invention adopts the method of setting the plastic sheath as an upper sheathing portion 12, a lower sheathing portion 13 and a terminal sheath 11, installing some of the multiple metal terminals 3 between the upper sheathing portion 12 and the terminal sheath 11, and installing another part of the multiple metal terminals 3 between the lower sheathing portion 13 and the terminal sheath 11, and providing a limiting groove 111a at the bottom of the accommodating groove 111 for accommodating the metal terminals 3, so that the metal terminals 3 form a raised structure 31 toward the limiting groove 111a, so that the upper sheathing portion 12 and the terminal sheath 11 press against the opposite sides of the multiple raised structures 31, and the lower sheathing portion 13 and the terminal sheath 11 press against the opposite sides of the multiple raised structures 31, thereby limiting the relative position of the metal terminals 3 in their extension direction, thereby replacing the one-piece molded insulating sheath 1, reducing the molding difficulty of the insulating sheath 1, improving the yield rate of the connector for transmitting high-speed signals, and reducing the production cost of the type-c male connector 100.

[0056] In one embodiment, see Figure 3 and Figure 4, multiple raised structures 31 have relative raised sides 311 and recessed sides 312, the raised sides 311 face the groove wall of the limiting groove 111a, and the upper enveloping portion 12 is protruded with multiple first limiting platforms 121 toward the recessed sides 312 of the multiple raised structures 31, and the multiple first limiting platforms 121 respectively press the multiple raised structures 31 close to the upper enveloping portion 12 against the groove bottoms of the multiple limiting grooves 111a; the lower enveloping portion 13 is protruded with multiple second limiting platforms 131 toward the recessed sides 312 of the multiple raised structures 31, and the multiple second limiting platforms 131 respectively press the multiple raised structures 31 close to the lower enveloping portion 13 against the groove bottoms of the multiple limiting grooves 111a.

[0057] Specifically, the raised structure 31 rises toward the limiting groove 111a. Considering that the thickness of the raised structure 31 is consistent with the thickness of the rest of the metal terminal 3, the raised structure 31 has a recessed side 312 corresponding to the raised side 311. The upper enclosing portion 12 and the lower enclosing portion 13 are respectively provided with a first limiting platform 121 and a second limiting platform 131 adapted to the raised structure 31, wherein the first limiting platform 121 and the second limiting platform 131 can be set as a square platform or as a cylindrical platform with a cross section, and their shapes can be adapted to the recessed side 312 of the raised structure 31 as needed. In this way, the limiting function of the multiple first limiting platforms 121 on the multiple metal terminals 3 in the extension direction of the metal terminal 3 can be further enhanced, and the limiting function of the multiple second limiting platforms 131 on the multiple metal terminals 3 in the extension direction of the metal terminal 3 can also be further enhanced.

[0058] In addition, the first limiting platform 121 and the second limiting platform 131 also have the function of limiting the metal terminal 3 in the width direction of the metal terminal 3, further strengthening the limiting function of the multiple first limiting platforms 121 and the multiple second limiting platforms 131 on the metal terminal 3.

[0059] In one embodiment, see Figure 3 and Figure 4 The upper enclosing portion 12 is provided with a first pin 123 protruding toward the lower enclosing portion 13, and the lower enclosing portion 13 is provided with a first hole 133 corresponding to the first pin 123. The lower enclosing portion 13 is provided with a second pin 134 protruding toward the upper enclosing portion 12, and the upper enclosing portion 12 is provided with a second hole 124 corresponding to the second pin 134; the circuit board 2 is provided with a card slot 21 on opposite sides, the upper enclosing portion 12 is provided with a first limiting portion 125 corresponding to the card slot 21, and the lower enclosing portion 13 is provided with a second limiting portion 135 corresponding to the card slot 21, and the first limiting portion 125 and the second limiting portion 135 are used to limit the relative position of the circuit board 2 in the extension direction of the metal terminal 3.

[0060] It is understood that the upper and lower enveloping portions 12 and 13 are mounted and fixed together by means of a pin and a socket. The upper and lower enveloping portions 12 and 13 can be mounted solely by means of the first pin 123 and the first socket 133, wherein the number of the first pin 123 and the first socket 133 can be one, two, or more. The upper and lower enveloping portions 12 and 13 can also be mounted solely by means of the second pin 134 and the second socket 124, wherein the number of the second pin 134 and the second socket 124 can be one, two, or more. In this embodiment, by providing the first pin 123 and the second socket 124 on the upper and lower enveloping portions 12, and providing the second pin 134 and the second socket 124 on the lower and upper enveloping portions 13, the mounting between the upper and lower enveloping portions 12 and 13 can be made more secure.

[0061] In addition, a card slot 21 is provided on opposite sides of the circuit board 2, and the card slot 21 is adapted to the first limiting portion 125 and the second limiting portion 135, that is, the first limiting portion 125 and the second limiting portion 135 correspond to each other and extend into the card slot 21 together, which is used for the relative position of the upper enclosing portion 12 and the lower enclosing portion 13 to prevent the multiple metal terminals 3 and the insulating sleeve 1 from moving relative to the circuit board 2.

[0062] In one embodiment, see Figures 5 to 7 The metal terminal 3 also includes an elastic abutment section 32 and a connecting section 33, which are respectively connected to the opposite ends of the raised structure 31. The elastic abutment section 32 extends in a direction away from the circuit board 2. The upper enveloping portion 12 presses the multiple connecting sections 33 close to the upper enveloping portion 12 onto one side of the circuit board 2, and the lower enveloping portion 13 presses the multiple connecting sections 33 close to the lower enveloping portion 13 onto the other opposite side of the circuit board 2.

[0063] It should be noted that part of the elastic abutting section 32 is located in the accommodating groove 111, and the other part of the elastic abutting section 32 is exposed to the plug-in cavity 112, which is used to form an abutting relationship with the female seat, thereby realizing signal transmission; and the connecting section 33 is used to abut against the circuit board 2, thereby realizing signal transmission. Among them, the connecting section 33 and the circuit board 2 can transmit information only through abutment, or can transmit information by providing multiple solder pads on the circuit board 2 so that multiple metal terminals 3 are soldered to the solder pads of the circuit board 2. The above two methods are optional embodiments of this embodiment. It should be noted that the upper enveloping portion 12 and the lower enveloping portion 13 have the function of pressing the connecting section 33 onto the circuit board 2, thereby further enhancing the stability of signal transmission between the multiple metal terminals 3 on the opposite sides of the circuit board 2 and the circuit board 2.

[0064] In one embodiment, see Figure 7 The type-c male connector 100 also includes two metal positive pressure springs 63 and two metal side pressure springs 64. The two metal positive pressure springs 63 are respectively arranged on the opposite sides of the terminal sleeve 11, and the first clamping blocks 712 are provided on the opposite sides of the upper enclosing portion 12, and the second clamping blocks 812 are provided on the opposite sides of the lower enclosing portion 13. The metal side pressure springs 64 are respectively clamped to the first clamping blocks 712 and the second clamping blocks 812.

[0065] In one embodiment, see Figures 8 to 10 The upper encapsulating portion 12 is provided with a plurality of first encapsulating segments 122 corresponding to the plurality of connecting segments 33, and the plurality of first encapsulating segments 122 respectively wrap the plurality of connecting segments 33 on one side of the circuit board 2; the lower encapsulating portion 13 is provided with a plurality of second encapsulating segments 132 corresponding to the plurality of connecting segments 33, and the plurality of second encapsulating segments 132 respectively wrap the plurality of connecting segments 33 on the other side of the circuit board 2.

[0066] It should be noted that in order to enable the upper encapsulating portion 12 and the lower encapsulating portion 13 to have better limiting and fixing functions for the metal terminal 3, the upper encapsulating portion 12 is provided with multiple first encapsulating segments 122 corresponding to the multiple connecting segments 33, so that the first encapsulating segments 122 wrap the multiple connecting segments 33 close to the first encapsulating portion, specifically, the first encapsulating segments 122 wrap the three surfaces of the metal terminal 3, that is, the surface of the metal terminal 3 away from the circuit board 2 and the two surfaces adjacent to the surface; similarly, the lower encapsulating portion 13 is provided with multiple second encapsulating segments 132 corresponding to the multiple connecting segments 33, so that the second encapsulating segments 132 wrap the multiple connecting segments 33 close to the second encapsulating portion, specifically, the second encapsulating segments 132 wrap the three surfaces of the metal terminal 3, that is, the surface of the metal terminal 3 away from the circuit board 2 and the two surfaces adjacent to the surface.

[0067] In one embodiment, see Figure 1 、 Figure 2 and Figure 11 The type-c male connector 100 further includes a metal shell 6 , which wraps the outer side of the insulating sleeve 1 .

[0068] It should be noted that the metal housing 6 comprises a first shell 61 and a second shell 62, which can be integrally connected or separate. In this embodiment, the first shell 61 primarily encases the insulating sheath 1, while the second shell 62 also encases the insulating sheath 1. Considering that the insulating sheath 1 is made of plastic, the metal housing 6 is used to encase it to prevent loss that could affect the connector's high-speed signal transmission. The wire-receiving portion 14 has recessed grooves 144 on opposite sides, and limit springs 621 protrude from the inner wall of the second shell 62, corresponding to these recessed grooves 144.

[0069] In one embodiment, see Figure 11 and Figure 12 The type-c male connector 100 includes a first wire pressing portion 7 and a second wire pressing portion 8, which are respectively arranged on opposite sides of the circuit board 2. The first wire pressing portion 7 and the second wire pressing portion 8 are respectively provided with a first shaft portion 721 and a second shaft portion 821. The first shaft portion 721 is rotatably installed between the first metal shell 6 and the circuit board 2, and the second shaft portion 821 is rotatably installed between the first metal shell 6 and the circuit board 2. The first wire pressing portion 7 crimps multiple core wires on one side of the circuit board 2, and the second wire pressing portion 8 is used to crimp multiple core wires on the other side opposite to the circuit board 2.

[0070] Specifically, the Type-C male connector 100 includes a first crimping portion 7 and a second crimping portion 8 for crimping a wire connected to the circuit board 2. The first crimping portion 7 and the second crimping portion 8 are disposed on opposite sides of the circuit board 2, such that the first crimping portion 7 crimps the wire on one side of the circuit board 2, and the second crimping portion 8 crimps the wire on the other side of the circuit board 2. It should be noted that a space is provided between the metal shell 6 and the circuit board 2 to accommodate a first pivot portion 721 of the first crimping portion 7 and a second pivot portion 821 of the second crimping portion 8. The first pivot portion 721 is rotatably mounted between the metal shell 6 and the circuit board 2, allowing the first crimping portion 7 to rotate relative to the metal shell 6. The second pivot portion 821 is rotatably mounted between the metal shell 6 and the circuit board 2, allowing the second crimping portion 8 to rotate relative to the metal shell 6. In this manner, once the wire is placed on the circuit board 2, the first crimping portion 7 and the second crimping portion 8 can be rotated to crimp the wire.

[0071] By crimping the core wire onto the circuit board 2 instead of soldering the core wire onto the circuit board 2, the risk of the pad of the circuit board 2 falling off can be effectively avoided. At the same time, the crimping force can fully ensure the smooth connection between the core wire end and the pad of the circuit board 2, which can improve production efficiency, save time and effort, increase the yield rate, simplify the performance testing steps, and thus greatly reduce processing costs and production difficulty.
