[0044] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0046] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication 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 used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. 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 contradictory or cannot be implemented, it should be deemed that such 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 requirements for information transmission speed are getting higher and higher, and the performance requirements for information transmission connectors are also getting higher and higher, requiring not only better materials and higher precision, but also more stringent process guarantees; therefore, using the existing production methods, the production difficulty has greatly increased the production cost and also greatly reduced the production yield. 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 yield of the connectors produced is often insufficient, and the processing cost is high.

[0049] In view of this, the present invention proposes a type-c male connector 100 to solve any one of the technical problems mentioned above. The type-c male connector proposed by the present invention can be used for ordinary USB4 data cables, and can also be used for various electronic composite data cables, such as Thunderbolt 4 data cables and optical fiber type-c data cables. The type-c male connector used for USB4 data cables is shown in the figure of the present invention.

[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, wherein 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 provided on opposite sides of the terminal sleeve 11; the circuit board 2 is installed on the upper connecting portion 12 and the lower connecting portion 13. Between the enclosing parts 13; multiple metal terminals 3 are electrically connected to the circuit board 2, and the 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 structure 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 wrap the multiple metal terminals 3, and plays the function of fixing and signal shielding the multiple metal terminals 3 to prevent the transmission signals between the multiple metal terminals 3 from interfering with each other. Generally, the insulating sleeve 1 is integrally formed by injection molding, but the requirements for the insulating sleeve 1 suitable for high-speed transmission connectors are relatively high. If an integral molding process is adopted, the yield rate that meets the industry standards of high-speed transmission connectors is not high, resulting in a high cost of manufacturing the connector. Therefore, in this embodiment, the insulating sleeve 1 is divided into two parts, and the insulating sleeve 1 includes 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 metal terminal 3 in the width direction. 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, so as to fix the relative position of the metal terminal 3 to prevent the metal terminal 3 from moving.

[0053] In addition, a plug-in cavity 112 is provided at one end of the terminal sleeve 11, and the plug-in cavity 112 is used to electrically connect the plurality of metal terminals 3 with the circuit board 2 in the female socket to facilitate signal transmission. The accommodating groove 111 is at least partially connected to the plug-in cavity 112, so that the metal terminal 3 can be exposed in the plug-in cavity 112, so that the metal terminal 3 can form a conflicting relationship with the female socket adapted to the male connector.

[0054] Furthermore, the terminal sleeve 11 is mainly used to accommodate multiple metal terminals 3, and the fixation of multiple metal terminals 3 requires that the upper and lower enveloping portions 12 and 13 form a matching relationship with the terminal sleeve 11. In order to better limit and fix the metal terminal 3, a limiting groove 111a is opened in the accommodating groove 111, so that the metal terminal 3 is partially accommodated in the limiting groove 111a, so that the metal terminal 3 is formed with a ridge structure 31 corresponding to the limiting portion. It should be noted that in order not to affect the transmission of high-speed signals by the metal terminal 3, the thickness of the ridge structure 31 is consistent with the thickness of the rest of the metal terminal 3 except the ridge structure 31. In this embodiment, the ridge structure 31 is raised toward the limiting groove 111a, so that the ridge structure 31 is basically in contact with the groove wall of the limiting groove 111a, and the upper enveloping portion 12 and the lower enveloping portion 13 are respectively crimped on the surface of the ridge structure 31 on the side away from the limiting groove 111a, so that the multiple metal terminals 3 are crimped in the multiple limiting grooves 111a. The metal terminal 3 is fixed in the above manner, and the metal terminal 3 is limited in the extension direction of the metal terminal 3, thereby replacing the integrally molded plastic sheath, reducing the molding difficulty of 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 terminal 3, so that the metal terminal 3 forms 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 terminal 3 in its extension direction, thereby replacing the integrally formed 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 manufacturing cost of the type-c male connector 100.

[0056] In one embodiment, see Figure 3 and Figure 4The multiple raised structures 31 have relative raised sides 311 and recessed sides 312, and the raised sides 311 face the groove wall of the limiting groove 111a. The upper enveloping portion 12 is provided with multiple first limiting platforms 121 protrudingly disposed toward the recessed sides 312 of the multiple raised structures 31. 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 provided with multiple second limiting platforms 131 protrudingly disposed toward the recessed sides 312 of the multiple raised structures 31. 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 is raised 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 enveloping portion 12 and the lower enveloping 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 arranged in a square platform or in a cylindrical shape 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 strengthened, 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 strengthened.

[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 first limiting platforms 121 and the 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 plug hole 133 corresponding to the first pin 123, and 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 plug 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 can be understood that the upper enveloping portion 12 and the lower enveloping portion 13 are installed and fixed by the cooperation of the pin and the socket. The upper enveloping portion 12 and the lower enveloping portion 13 can be installed only by the cooperation 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 enveloping portion 12 and the lower enveloping portion 13 can also be installed only by the cooperation 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 the present embodiment, by providing the first pin 123 and the second socket 124 on the upper enveloping portion 12, and providing the second pin 134 and the second socket 124 on the lower enveloping portion 13, the installation between the upper enveloping portion 12 and the lower enveloping portion 13 can be made more secure.

[0061] In addition, a card slot 21 is opened on the 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 connection section 33, which are respectively connected to the opposite ends of the protruding structure 31, and the elastic abutment section 32 extends in a direction away from the circuit board 2. The upper enveloping portion 12 crimps the multiple connection sections 33 close to the upper enveloping portion 12 on one side of the circuit board 2, and the lower enveloping portion 13 crimps the multiple connection sections 33 close to the lower enveloping portion 13 on the other side opposite to the circuit board 2.

[0063] It should be noted that part of the elastic abutment section 32 is located in the accommodating groove 111, and the other part of the elastic abutment section 32 is exposed to the plug-in cavity 112, which is used to form an abutment 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 be provided with multiple pads on the circuit board 2, so that multiple metal terminals 3 are welded to the pads of the circuit board 2 to transmit information. The above two methods are optional embodiments of this embodiment. It should be noted that the upper enveloping part 12 and the lower enveloping part 13 have the function of crimping the connecting section 33 on 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.

In this embodiment, the first shell 61 is mainly used to wrap the insulating sleeve 1, and the second shell 62 is also used to wrap the insulating sleeve 1. Considering that the insulating sleeve 1 is made of plastic, in order to prevent its loss and thus affect the transmission of high-speed signals by the connector, it is wrapped by the metal shell 6. The opposite sides of the wire placement portion 14 are respectively provided with recessed grooves 144, and the inner wall of the second shell 62 is provided with a limit spring 621 corresponding to the recessed groove 144.

[0069] In one embodiment, see Fig.11 and Fig.12 The type-c male connector 100 includes a first wire pressing portion 7 and a second wire pressing portion 8, and the first wire pressing portion 7 and the second wire pressing portion 8 are respectively arranged on opposite sides of the circuit board 2, and 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, and 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, which are used to crimp the core wire connected to the circuit board 2. The first crimping portion 7 and the second crimping portion 8 are respectively arranged on opposite sides of the circuit board 2, so that the first crimping portion 7 crimps the core wire on one side of the circuit board 2, and the second crimping portion 8 crimps the core wire on the other side of the circuit board 2. It should be noted that there is an accommodating space between the metal shell 6 and the circuit board 2, which is used to accommodate the first rotating shaft portion 721 of the first crimping portion 7 and the second rotating shaft portion 821 of the second crimping portion 8.

In this way, when the core wire is placed on the circuit board 2, the core wire can be crimped by rotating the first crimping portion 7 and the second crimping portion 8.

[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 labor, increase the yield rate, simplify performance testing steps, and thus greatly reduce processing costs and production difficulties.

When the first wire pressing part 7 and the second wire pressing part 8 are rotated to the point where the first wire pressing part 7 and the second wire pressing part 8 are buckled, the core wires in the plurality of first wire grooves 142 and the core wires in the plurality of second wire grooves 143 are just crimped by the first wire pressing part 7 and the second wire pressing part 8. By providing a plurality of first wire grooves 142 and a plurality of second wire grooves 143 on the wire placing part 14, the crimping effect of the core wires can be improved.
