[0002] In order to exchange data, many electronic devices are equipped with USB interfaces. The USB interface has a hot-swap function, which can quickly connect to a variety of external electronic devices. After continuous evolution, the new interface form of the USB interface is Type-C. Type-C has no difference in the positive and negative directions and can be plugged in and out at will, and has been widely used, gradually replacing the original Type-B and Type-A. Under the scale effect, many external electronic devices have actively adopted the Type-C interface.
[0003] Now many tablets, mobile phones, mobile power banks and Bluetooth speakers have Type-C interfaces. Users tend to use the Type-C data cable on the same charging adapter to charge or power different types of products. When users get new types of electronic devices, such as newly launched fans, they will directly use the existing Type-C data cable to plug it into the Type-C interface of the fan for charging or powering, which is prone to voltage mismatch and thus damage the fan.

[0024] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.
[0025] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of the male head 100 and the female head 200 of the anti-misinsertion TPYE-C connector when they are plugged together. The female head 200 is generally set at the fan end, and the male head 100 is generally on the TPYE-C data cable or the Type-C interface extension cable. The uneven plugging surface 300 between the male head 100 and the female head 200 plays an anti-misinsertion role. Both sides of the suitable male head 100 can be inserted into the female head 200. Only when the male head 100 is fully inserted into the female head 200, the male head 100 and the female head 200 are electrically connected, thereby connecting the fan with the adapter and the PC port of the computer to power the fan and control signals or charge it.
[0026] refer to Figures 1 to 6A TPYE-C connector for preventing mis-insertion includes a male connector 100 and a female connector 200. The male connector 100 includes a first plug 1 and a first shell 2. The female connector 200 includes a second plug 3 and a second shell 4. The first plug 1 and the second plug 3 are respectively exposed from the first shell 2 and the second shell 4. The plugging end surfaces of the first shell 2 and the second shell 4 are both configured as uneven plugging surfaces 300. The uneven plugging surfaces 300 on both sides of the first shell 2 in the thickness direction are both provided with a protrusion 21 extending in the plugging direction of the male connector 100. The uneven plugging surfaces 300 on both sides of the second shell 4 in the thickness direction are both provided with a protrusion 21 extending in the plugging direction of the male connector 100. A groove 41 is provided which is recessed in the plugging direction of the male plug 100, the end face of the first plug 1 is higher than the uneven plugging surface 300 of the first shell 2, and the end face of the second plug 3 is higher than the bottom of the groove 41 and is not higher than the remaining uneven plugging surface 300 of the second shell 4; during the plugging process of the male plug 100 and the female plug 200, only when the protrusion 21 of the first shell 2 is fully inserted into the groove 41 of the second shell 4, can the first plug 1 be fully inserted into the second plug 3 and the electrical connection between the first plug 1 and the second plug 3 be realized, so as to form an anti-misplugging structure between the male plug 100 and the female plug 200.
[0027] The anti-misinsertion TPYE-C connector of this embodiment realizes mis-insertion prevention through the uneven plugging surface 300 between the male head 100 and the female head 200. When the male head 100 of the TPYE-C data cable that is not compatible with the electronic device is inserted into the female head 200 on the electronic device, the terminals of the incompatible male head 100 cannot contact the terminals of the female head 200, thereby protecting the electronic device from being burned; the two protrusions 21 symmetrically arranged on the first shell 2 and the two grooves 41 symmetrically arranged on the second shell 4 can ensure that both sides of the male head 100 can be inserted into the female head 200, so as to realize the function that both sides of the TPYE-C interface can be plugged in.
[0028] It should be further explained that the first plug 1 and the corresponding PCB board and wire are packaged together in the first shell 2, and the second plug 3 and the corresponding PCB board and wire are packaged together in the second shell 4 to ensure the safety of the internal circuits of the male plug 100 and the female plug 200.
[0029] In order to avoid the male connector 100 of the existing TPYE-C data cable being directly inserted into the female connector 200 of this embodiment, in this embodiment, Figure 5 , the insertion depth of the first shell 2 and the second shell 4 is greater than the insertion depth of the first plug 1 and the second plug 3 .
[0030] It is understandable that, with such a configuration, the plugs of the existing TPYE-C interface male plug 100 will be slightly longer. In order to prevent these existing slightly longer TPYE-C interface male plug 100 plugs from contacting the second plug 3 of the female plug 200, the position of the second plug 3 is designed to be deeper, so that the depth of the first plug 1 and the second plug 3 will be smaller than the depth of the first shell 2 and the second shell 4. When the male plug 100 and the female plug 200 of this embodiment are plugged together, the first plug 1 will start to be plugged together with the second plug 3 only after the first shell 2 and the second shell 4 are plugged together to a certain depth. At the same time, under the guidance of the plugging of the first shell 2 and the second shell 4, the first plug 1 can be more accurately inserted into the second plug 3, reducing the probability of damage to the terminals in the first plug 1 and the second plug 3.
[0031] In order to guide the insertion of the male connector 100 and the female connector 200, in this embodiment, Figures 1 to 4 The protrusion 21 is provided with a first limiting surface 22 and two first guiding surfaces 23, the two first guiding surfaces 23 are symmetrically arranged on both sides of the first limiting surface 22, and the first guiding surface 23 is inclined toward the plugging direction of the male plug 100, and the groove 41 is provided with a second limiting surface 42 and two second guiding surfaces 43, the second limiting surface 42 is the groove bottom of the groove 41, and the two second guiding surfaces 43 are symmetrically arranged on both sides of the second limiting surface 42, and the second guiding surfaces 43 are inclined toward the opposite direction of the plugging of the male plug 100. During the plugging process of the male plug 100 and the female plug 200, the first guiding surface 23 cooperates with the second guiding surface 43 to guide the first plug 1 to be inserted into the second plug 3, and the first limiting surface 22 contacts the second limiting surface 42 to limit the plugging depth of the first plug 1 and the second plug 3.
[0032] It can be understood that, with such a configuration, when the male connector 100 and the female connector 200 are plugged in, the first guide surface 23 first contacts the second guide surface 43, and the inclined first guide surface 23 and the second guide surface 43 gradually collide and guide the plugging process of the male connector 100 and the female connector 200, so that the male connector 100 and the female connector 200 are gradually aligned in the center, until the first plug 1 is inserted into the second plug 3, and the first limit surface 22 contacts the second limit surface 42, so that the plugging of the male connector 100 and the female connector 200 is completed.
[0033] In order to ensure that the first plug 1 and the second plug 3 are plugged into each other, in this embodiment, reference Figure 3 and Figure 6 The protruding portion 21 is provided with a avoiding groove 24 near the side wall of the first plug 1 , and during the plugging process of the male plug 100 and the female plug 200 , the second plug 3 is inserted into the avoiding groove 24 .
[0034] It can be understood that, with such a configuration, the protrusion 21 is closer to the end face of the first plug 1. During the process of inserting the first plug 1 into the second plug 3, the end face of the second plug 3 will exceed the first limiting surface 22 of the protrusion 21. The avoidance groove 24 can prevent the second plug 3 from contacting the protrusion 21, thereby ensuring that the protrusion 21 will not block the second plug 3, so that the first plug 1 and the second plug 3 can be well plugged in.
[0035] In this embodiment, reference Figure 4 and Figure 5 A circular groove 44 is provided between the second housing 4 and the outer wall of the second plug 3 , and the bottom of the groove 44 is flush with the bottom of the groove 41 .
[0036] It is understandable that, with such a configuration, after the first shell 2 and the second shell 4 are plugged into each other, the groove 44 will form a chamber, and the air in the chamber can better help the male connector 100 to be pulled apart from the female connector 200.
[0037] In order to improve the plugging force between the first plug 1 and the second plug 3, in this embodiment, reference Figure 5 A pair of hooks 11 are provided in the first plug 1, and barbs 32 are provided on both sides of the plug tongue 31 inside the second plug 3. During the plugging process of the male plug 100 and the female plug 200, the clamping ends of the hooks 11 are clamped and fixed with the barbs 32.
[0038] It can be understood that, with such a configuration, after the male plug 100 and the female plug 200 are plugged together, the two hooks 11 on the first plug 1 are respectively plugged and fixed with the two barbs 32 on the plug tongue 31 of the second plug 3, and the two hooks 11 hold the plug tongue 31 by their own elasticity, thereby improving the plugging force between the first plug 1 and the second plug 3, and preventing the male plug 100 and the female plug 200 from loosening by themselves.
[0039] In this embodiment, among the PIN positions of the TPYE-C connector, positions A5 and B5 are 12V power terminals, positions A6 and B6 are speed signal terminals, positions A7 and B7 are data transmission terminals, positions A8 and B8 are PWM modulation signal terminals, and positions A1, B1, A12, and B12 are ground terminals. By redefining the PIN positions, foolproofing is done in product intermatching, so that the existing TPYE-C male plug 100 is inserted into the female plug 200 of this embodiment. Due to the mismatch of the PIN, the electronic device cannot work after the existing TPYE-C male plug 100 is plugged into the female plug 200 of the electronic device, thereby avoiding the problem of short circuit and burning of the electronic device due to non-standard interface size and violent use of the plug interface.
[0040] The anti-mis-insertion TPYE-C connector of this embodiment realizes mis-insertion prevention through the uneven plugging surface 300 between the male head 100 and the female head 200. Only when the male head 100 is fully inserted into the female head 200, the male head 100 and the female head 200 are electrically connected, thereby connecting the fan with the adapter and the PC port of the computer to supply power to the fan and control signals or charge; when the male head 100 of the TPYE-C data cable that is not compatible with the electronic device is inserted into the female head 200 on the electronic device, the terminals of the incompatible male head 100 and the terminals of the female head 200 are not compatible. The two protrusions 21 symmetrically arranged on the first shell 2 and the two grooves 41 symmetrically arranged on the second shell 4 can ensure that both sides of the male connector 100 can be inserted into the female connector 200, so as to realize the function that both sides of the TPYE-C interface can be plugged in. When the male connector 100 and the female connector 200 are plugged in, the first guide surface 23 and the second guide surface 43 are used to guide the male connector 100 and the female connector 200 to gradually align in the center, so that the male connector 100 and the female connector 200 can be better plugged in.
[0041] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
