[0007] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art. SUMMARY

[0008] An object of the utility model is to provide a connector male head, a connector female head and a waterproof connector assembly, which can effectively solve the problems of easy water ingress and short circuit and small power supply current of the existing FAKRA connector.

[0055] In this embodiment, the waterproof connector assembly includes a male connector head and a female connector head.

[0056] See Figure 1 The male connector 1 includes:

[0057] A male connector insulating housing 101 is provided with a male connector insertion / removal cavity 1011 at one end face of the male connector insulating housing 101;

[0058] The male waterproof component 102 extends into the male plug-in cavity 1011 and surrounds it to form a conductive cavity 1021;

[0059] Male probe assembly 103, which is used to transmit power supply current, penetrates the male insulating housing 101 along the axial direction and extends into the conductive cavity 1021;

[0060] The male coaxial terminal 104 is used to transmit signal current. It passes through the male insulating housing 101 along the axial direction and extends into the conductive cavity 1021.

[0061] Accordingly, see Figure 2 The connector female head 2, used for plugging and unplugging with the connector male head 1, includes:

[0062] The female connector insulating housing 201 has a female connector insertion / removal part 2011 at one end face for inserting into the space between the male connector waterproof component 102 and the male connector insulating housing 101; wherein, the female connector insertion / removal part 2011 has a female connector insertion / removal cavity, and the female connector insertion / removal cavity has a female connector boss 2012 for inserting into the conductive cavity 1021.

[0063] A female waterproof component 202 is attached to the inner wall of the female insertion cavity and surrounds the female boss 2012; wherein, a waterproof cavity for the male waterproof component 102 to be inserted is provided between the female waterproof component 202 and the female boss 2012.

[0064] The female probe assembly 203 is inserted into the female boss 2012 along the axial direction of the female insulating shell 201, and is used to transmit power supply current after docking with the male probe assembly 103.

[0065] The female coaxial terminal 204 is inserted into the female boss 2012 along the axial direction of the female insulating shell 201, and is used to transmit signal current after being connected with the male coaxial terminal 104.

[0066] Furthermore, both the male probe assembly 103 and the female probe assembly 203 include a positive power supply probe and a negative power supply probe, wherein the positive power supply probe and the negative power supply probe of the female probe assembly 203 are provided with probe slots for the power supply probe corresponding to the male probe assembly 103 to be inserted.

[0067] Similarly, the female coaxial terminal 204 is provided with a coaxial slot for the male coaxial terminal 104 to be inserted.

[0068] The male connector 1, female connector 2, and waterproof connector assembly provided in this embodiment, when the male connector 1 and female connector 2 are mated:

[0069] On the one hand, the male waterproof component 102 and the female waterproof component 202 abut against each other to surround and seal the probe assembly and coaxial terminal used for conducting electricity, preventing water ingress and short circuit;

[0070] On the other hand, the male probe assembly 103 mates with the female probe assembly 203 to form a power supply current transmission path; the male coaxial terminal 104 mates with the female coaxial terminal 204 to form a signal current transmission path. This separation of power supply and signal current design avoids the situation where both currents are transmitted through the same conductive component, reducing interference from the power supply current to the signal current and improving the transmission quality of high-frequency signals. Furthermore, the separate transmission of power supply and signal currents allows the connector to withstand larger currents, expanding its application range.

[0071] Therefore, the male connector 1, female connector 2, and waterproof connector assembly provided by this utility model can effectively solve the problems of existing FAKRA connectors being prone to water ingress and short circuits, as well as having low power supply current.

[0072] In this embodiment, the male waterproof connector 102 is a rigid insulating component, while the female waterproof connector 202 is a flexible insulating component. The rigid insulating component possesses high strength and stability, ensuring the connector maintains a stable shape and size during insertion and removal, thus providing a reliable mating interface. The flexible insulating component has good elasticity and adaptability, allowing it to fit tightly against the male waterproof connector 102, forming a more effective sealing structure and further preventing the intrusion of moisture and impurities.

[0073] Optionally, the rigid insulating component is a rigid plastic component made of materials such as polycarbonate (PC), polyamide (PA), or polybutylene terephthalate (PBT).

[0074] Accordingly, the flexible insulating component is a flexible rubber component (e.g., silicone rubber, fluororubber, nitrile rubber, etc.), a flexible plastic component (e.g., polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polyethylene (PE), etc.), or a fluorosilicone rubber component, etc.

[0075] Optional, see Figure 3 The female waterproof component 202 is provided with a plurality of corrugated protrusions 2021 for sealing and abutting against the outer wall of the male waterproof component 102, and a water storage space 2022 is provided between two adjacent corrugated protrusions 2021.

[0076] The corrugated boss 2021 has a certain degree of elasticity, which can adapt to the slight deformation that may occur in the male waterproof component 102 during insertion and removal, maintaining a good sealing effect. When the male connector 1 and the female connector are inserted, the corrugated boss 2021 is in close contact with the outer wall of the male waterproof component 102, forming multiple sealing barriers to effectively prevent moisture and dust from entering the connector. During the use of the connector, even if a small amount of moisture seeps in, it can be contained by the water storage space 2022, preventing further penetration of moisture into the connector.

[0077] The combined design of the corrugated boss 2021 and the water reservoir 2022 significantly improves the connector's waterproof performance. The corrugated boss 2021 provides multiple sealing barriers, while the water reservoir 2022 effectively contains and drains infiltrated moisture. Together, they ensure that the connector maintains reliable electrical connection and safety in humid or underwater environments.

[0078] In summary, the male connector 1, female connector 2, and waterproof connector assembly provided in this embodiment have the following advantages:

[0079] ① Excellent waterproof and dustproof performance: Through the combination of rigid and flexible insulation components, as well as the design of the corrugated boss 2021 and water storage space 2022, multiple sealing barriers are achieved, effectively preventing the intrusion of moisture and impurities, and making it suitable for outdoor or humid environments.

[0080] ② Separation design of power supply current and signal current: reduces the interference of power supply current on signal current, improves the transmission quality of high frequency signals, and enables the connector to withstand greater current, thus expanding the application range.

[0081] ③ Compact structure: The overall structure is small and compact, saving space and helping to meet the market demand for miniaturized equipment.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
