Existing Type-C female electrical connectors typically consist of a metal housing, an insulating body, and several terminals. The terminals are embedded in the insulating body, and the housing covers the insulating body. Existing electrical connectors are complex in structure and have numerous components. In particular, due to the large number of terminals used to transmit power or electrical signals, the connectors consist of multiple terminals and latches, resulting in high processing costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a Type-C female electrical connector.

[0004] In order to solve the above technical problems, the Type-C female electrical connector of the present invention includes an insulating body and a terminal embedded in the insulating body, wherein the terminal includes a positive power terminal and a ground terminal, and the ground terminal is provided with a clamping portion. The Type-C female electrical connector is also provided with an independent lock, and the ground terminal and the lock are respectively arranged on both sides of the insulating body.

[0005] Preferably, the docking portion of the positive power terminal and the docking portion of the ground terminal are arranged on the same surface of the insulating body.

[0006] Preferably, the docking portion of the positive power terminal and the docking portion of the ground terminal are arranged on different surfaces of the insulating body.

[0007] Preferably, a balancing protrusion is provided on the insulating body.

[0008] Preferably, the positive power terminal includes a fixing portion, a docking portion connected to a first end of the fixing portion, and a welding foot connected to a second end of the fixing portion. The second end of the fixing portion of the positive power terminal is further provided with a connecting portion.

[0009] Preferably, the grounding terminal includes a fixing portion, a docking portion connected to a first end of the fixing portion, and a welding foot connected to a second end of the fixing portion. The second end of the fixing portion of the grounding terminal is further provided with a material connecting portion.

[0010] Preferably, the latch is provided with a welding foot and a material connecting portion.

[0011] Preferably, the positive power terminal, the ground terminal and the lock are made of the same material, and the positive power terminal, the ground terminal and the lock are all provided with connecting parts, and the connecting part of the positive power terminal, the connecting part of the ground terminal and the connecting part of the lock are located on the same reference plane.

[0012] Preferably, the power positive terminal, the ground terminal, and the lock are made of steel or copper.

[0013] Preferably, the positive power terminal, the ground terminal and the latch are all provided with welding feet, and the welding feet of the positive power terminal, the ground terminal and the latch are all provided with through holes.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] like Figure 1-4 As shown, the Type-C female electrical connector of this embodiment includes a metal housing 2000, an insulating body 3000, and terminals embedded in the insulating body 3000. The terminals include a positive power terminal 2 and a ground terminal 1. The ground terminal 1 is provided with a retaining portion 15. The Type-C female electrical connector also has an independent latch 3. The ground terminal 1 and the latch 3 are respectively provided on both sides of the insulating body 3000. The latch 3 is provided with a fixing portion 31.

[0030] In this embodiment, the docking portion 22 of the positive power terminal 2 and the docking portion 12 of the ground terminal 1 are arranged on the same surface of the insulating body. In this way, on the one hand, processing and electroplating are facilitated, thereby reducing the cost of processing and electroplating; on the other hand, when plugged into the male connector, the Type-C female electrical connector can be prevented from deflecting and causing poor electrical contact, thereby making the electrical connection between the two more stable. Two balancing protrusions 3001 are provided on the side of the insulating body 3000 where the docking portion is not provided. As a simple variation, the side of the insulating body 3000 where the docking portion is not provided can also be thickened as a whole.

[0031] In this embodiment, the positive power supply terminal 2 includes a fixing portion 21, a docking portion 22 connected to a first end of the fixing portion 21, and a welding leg 23 connected to a second end of the fixing portion 21. A material connection portion 26 is further provided at the second end of the fixing portion 21 of the positive power supply terminal 2. The provision of the material connection portion 26 eliminates the need for the welding leg 23 of the positive power supply terminal 2 to be connected to a material strip, thereby improving the processing accuracy of the welding leg 23 and facilitating the design of a wider welding leg, thereby increasing the gripping force of the welding plate. Furthermore, the material connection portion is directly connected to the fixing portion, making the fixing portion more stable during processing and eliminating the need for an auxiliary material connection portion at the front end of the terminal, thereby saving materials and costs.

[0032] In this embodiment, the ground terminal 1 includes a fixing portion 11, a docking portion 12 connected to a first end of the fixing portion 11, and a solder leg 13 connected to a second end of the fixing portion 11. The second end of the fixing portion 11 of the ground terminal 1 is further provided with a material connection portion 16. The provision of the material connection portion 16 eliminates the need for the solder leg 13 of the ground terminal 1 to be connected to a material strip, thereby improving the processing accuracy of the solder leg 13 and facilitating the design of a wider solder leg, thereby increasing the gripping force of the solder plate. Furthermore, the direct connection between the material connection portion and the fixing portion makes the fixing portion more stable during processing and eliminates the need for an auxiliary material connection portion at the front end of the terminal, thereby saving materials and costs.

[0033] In this embodiment, the positive power terminal 2, the ground terminal 1, and the latch 3 are made of the same material. Furthermore, the positive power terminal 2, the ground terminal 1, and the latch 3 are made of the same piece of material, and the connecting portion 26 of the positive power terminal 2 and the connecting portion 16 of the ground terminal 1 are located on the same reference plane.

[0034] In this embodiment, the positive power terminal 2, ground terminal 1, and latch 3 are made of steel. This ensures the wear resistance and strength of the latch portion 15 of the ground terminal 1 and the latch 3. Of course, to improve the conductivity of the positive power terminal 2 and ground terminal 1, they can be plated with a conductive coating.

[0035] In this embodiment, the Type-C female electrical connector is further provided with a suction sleeve.

[0036] The Type-C female electrical connector of the present invention includes only a ground terminal, a positive power terminal, and an independent latch. This eliminates the other terminals and latch in the Type-C female electrical connector in the prior art, significantly reducing the number of components in the Type-C female electrical connector, significantly lowering material costs and simplifying the processing, thereby significantly reducing production costs. By providing the latch, the side with the independent latch does not need to be equipped with a ground terminal, further reducing the number of components, lowering costs, and improving production efficiency and product yield.

[0037] In this embodiment, the Type-C female electrical connector is further provided with a suction sleeve 1000. The suction sleeve 1000 can protect the insulating body and the mating portion of the terminal and facilitate suction during the SMT automated process.

[0038] As a simple variation of this embodiment, the positive power terminal, the ground terminal, and the lock are made of copper.

[0039] Example 2:

[0040] like Figure 5-8 As shown, the Type-C female electrical connector of this embodiment includes an insulating body 5000 and a terminal embedded in the insulating body 5000, wherein the terminal includes a positive power terminal 92 and a grounding terminal 91, and the grounding terminal 91 is provided with a clamping portion 915. The Type-C female electrical connector is also provided with an independent lock 93, and the grounding terminal 91 and the lock 93 are respectively arranged on both sides of the insulating body 5000.

[0041] In this embodiment, the docking portion 922 of the positive power terminal 92 and the docking portion 912 of the ground terminal 91 are provided on different surfaces of the insulating body. The surface of the insulating body 5000 provided with the docking portion is provided with a balancing protrusion. Specifically, Figure 6 As shown, the surface 5001 provided with the docking portion 912 is provided with a balancing protrusion 5003. Figure 7 As shown, the surface 5002 with the docking portion 922 is provided with a balancing protrusion 5004. By providing the balancing protrusion, the Type-C female electrical connector can be prevented from deflecting when mating with the male connector, which may cause poor electrical contact, making the electrical connection between the two more stable.

[0042] In this embodiment, the positive power terminal 92 includes a fixing portion 921, a docking portion 922 connected to a first end of the fixing portion 921, and a solder leg 923 connected to a second end of the fixing portion 921. The second end of the fixing portion 921 of the positive power terminal 92 is also provided with a material connection portion 926. The provision of the material connection portion 926 eliminates the need for the solder leg 923 of the positive power terminal 92 to be connected to the material strip, thereby improving the processing accuracy of the solder leg 923 and facilitating a wider design for the solder leg, thereby increasing the grip of the welding plate. Furthermore, the direct connection between the material connection portion and the fixing portion makes the fixing portion more stable during processing, eliminating the need for an auxiliary material connection portion at the front end of the terminal, thereby saving materials and costs. The solder leg 923 is provided with a through hole 9231. The provision of the through hole 9231 allows solder to enter the through hole 9231 during welding, thereby achieving a more secure weld.

[0043] In this embodiment, the grounding terminal 91 includes a fixing portion 911, a docking portion 912 connected to a first end of the fixing portion 911, and a solder leg 913 connected to a second end of the fixing portion 911. The second end of the fixing portion 911 of the grounding terminal 91 is also provided with a material connection portion 916. The provision of the material connection portion 916 eliminates the need for the solder leg 913 of the grounding terminal 91 to be connected to the material strip, thereby improving the processing accuracy of the solder leg 913 and facilitating a wider design for the solder leg, thereby increasing the grip on the welding plate. Furthermore, the direct connection between the material connection portion and the fixing portion makes the fixing portion more stable during processing, eliminating the need for an auxiliary material connection portion at the front end of the terminal, thereby saving materials and costs. The solder leg 913 is provided with a through hole 9131. The provision of the through hole 9131 allows solder to enter the through hole 9131 during welding, thereby achieving a more secure weld.

[0044] In this embodiment, the positive power terminal 92, the ground terminal 91, and the latch 93 are made of the same material. Furthermore, the positive power terminal 92, the ground terminal 91, and the latch 93 are made of the same block of material, and the connecting portion 926 of the positive power terminal 92 and the connecting portion 916 of the ground terminal 91 are located on the same reference plane.

[0045] In this embodiment, the positive power terminal 92, ground terminal 91, and latch 93 are made of steel. This ensures the wear resistance and strength of the latch portion 915 of the ground terminal 91 and the latch 93. Of course, to improve the conductivity of the positive power terminal 92 and the ground terminal 91, they can be plated with a conductive coating.

[0046] In this embodiment, the Type-C female electrical connector is further provided with a suction sleeve 4000. By providing the suction sleeve 4000, the insulating body and the mating portion of the terminal can be protected, and it is also convenient to suck during the SMT automated process.

[0047] Since the Type-C female electrical connector of the present invention includes only one ground terminal, one positive power terminal and an independent lock, it eliminates the other terminals and one lock in the Type-C female electrical connector in the prior art except for the ground terminal and the positive power terminal, thereby greatly reducing the number of components of the Type-C female electrical connector, significantly reducing material costs, and greatly simplifying the processing technology, thereby significantly reducing production costs, improving production yield, and improving production efficiency.

[0048] As a simple variation of this embodiment, the positive power terminal, the ground terminal, and the lock are made of copper.

[0049] Example 3:

[0050] like Figure 9 As shown, the Type-C female electrical connector of this embodiment includes a positive power terminal 82 and a ground terminal 81. The ground terminal 81 also has a retaining portion. The Type-C female electrical connector also has an independent latch 83. This embodiment differs from Example 2 in that the latch 83 also has a solder pin 833. By providing solder pins 833 on the latch 83, the connection between the Type-C female electrical connector and the PCB board is more secure. The latch 83 also has a material connection portion 836. This material connection portion 836 eliminates the need for the solder pins 833 of the latch 83 to be connected to the material strip, thereby improving the processing accuracy of the solder pins 833 and facilitating the design of wider solder pins, thereby improving the grip of the solder board. Furthermore, the direct connection between the material connection portion and the fixing portion makes the fixing portion more stable during processing and eliminates the need for an auxiliary material connection portion at the front end of the terminal, thereby saving materials and costs. The solder leg 813 of the grounding terminal 81 is provided with a through-hole 8131, the solder leg 823 of the positive power supply terminal 82 is provided with a through-hole 8231, and the solder leg 833 of the latch 83 is provided with a through-hole 8331. These through-holes allow solder to enter during welding, thereby ensuring a more secure weld. The connecting portion of the positive power supply terminal 82, the connecting portion of the grounding terminal 81, and the connecting portion 836 of the latch 83 are located on the same reference plane.

[0051] Example 4:

[0052] like Figure 10 As shown, the Type-C female electrical connector of this embodiment includes a positive power terminal 72 and a ground terminal 71. The ground terminal 71 also has a retaining portion, and the Type-C female electrical connector is also provided with an independent latch 73. This embodiment differs from Example 3 in that the solder pins 713 of the ground terminal 71, the solder pins 723 of the positive power terminal 72, and the solder pins 733 of the latch 73 are bent toward the sides.

[0053] Example 5:

[0054] like Figure 11 As shown, the difference between the Type-C female electrical connector of this embodiment and that of Embodiment 2 is that a positioning column 7009 is provided on the insulating body 7000 .
