[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should also be understood that the terminology used in this application specification is merely for describing specific realities within the scope of this application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] like Figures 1 to 2As shown, this application provides a first connector 10 for cooperating with a second connector 20 to transmit electrical signals, such as power supply or other data. The first connector 10 and the second connector 20 can be applied to, but are not limited to, a cleaning robot 200, and can also be applied to other robots 200 or other devices equipped with the second connector 20. The following detailed description primarily uses a cleaning robot 200 as an example to clearly illustrate the first connector 10 shown in this application. Of course, the first connector 10 shown in this embodiment can also be applied to other robots 200 besides the cleaning robot 200, such as lawnmowers.

[0038] like Figures 3 to 6 As shown, according to a first aspect of this application, this application provides a first connector 10, including a first connecting portion 11 and a first conductive terminal 12. The first conductive terminal 12 is disposed on the first connecting portion 11, providing support for the first conductive terminal 12. The shape of the first connecting portion 11 can be designed according to the needs of the assembly space and other components, and is not limited to the shape shown in this embodiment. At least one of the first connecting portion 11 and the first conductive terminal 12 has a mating groove 10a. A wiper 13 is provided on the side of the mating groove 10a near the opening. The wiper 13 is used to wipe away liquid from the second conductive terminal 22 that mates with the first conductive terminal 12, preventing liquid from entering the conductive contact area. This solves the problem of electrochemical corrosion caused by the first conductive terminal 12 and the second conductive terminal 22 contacting liquid, greatly improving the service life of the first connector and avoiding the potential charging hazard caused by water stains during connection, thus ensuring signal transmission stability. The liquid includes, but is not limited to, water and electrolyte.

[0039] After adopting the above technical solution, since the wiper 13 is located at the opening of the insertion slot 10a, it can contact the second conductive terminal 22 immediately during the process of inserting the second conductive terminal 22 into the insertion slot 10a. This can wipe away the liquid on the surface of the second conductive terminal and prevent the liquid from entering the conductive contact area. This not only avoids electrochemical corrosion from the source, but also solves the problem of poor contact between the second conductive terminal 22 and the first conductive terminal 12 in a humid environment. It ensures reliable contact between the second conductive terminal 22 and the first conductive terminal 12, and avoids the interruption of the connection between the second conductive terminal 22 and the first conductive terminal 12 due to liquid. This greatly improves the service life of the connector assembly 100 and avoids the potential charging hazard caused by water stains during connection, thus ensuring the stability of signal transmission.

[0040] For example, when the power is on, the liquid on the surfaces of the second conductive terminal 22 and the first conductive terminal 12 can not only accelerate the oxidation reaction, but also cause the contact resistance to increase due to the corrosion products, thus affecting the conductivity. Therefore, this application solves the problem of electrochemical corrosion caused by the contact of the second conductive terminal 22 and the first conductive terminal 12 with liquid by designing the wiper 13, thereby improving the reliability and service life of the connector in a humid environment.

[0041] It should be noted that the wiper 13 can be integrally formed with the first connecting part 11, and the wiper 13 can also be fixed in the insertion groove 10a by assembly. For example, it can be made of wear-resistant silicone or rubber material, conductive polymer with microporous structure, etc. This application does not limit it. The main purpose is to solve the problem that the connector assembly 100 is prone to increased contact resistance or instantaneous circuit breakage due to residual liquid on the surface of conductive terminals in humid environments, thereby affecting the stability of signal / power transmission.

[0042] In one alternative implementation, such as Figures 2 to 6 As shown, the first connecting portion 11 has a first mating surface for cooperating with the second connector 20, and the insertion groove 10a passes through the first mating surface. The second connector 20 has a second connecting portion 21 and a second conductive terminal 22. The second connecting portion 21 has a second mating surface for cooperating with the first connecting portion 11, and the second conductive terminal 22 is disposed on the second connecting portion 21 and protrudes from the second mating surface so that it can be inserted into the insertion groove 10a and electrically connected to the first conductive terminal 12, thereby realizing the transmission or interaction of electrical signals between the first connector 10 and the second connector 20.

[0043] For example, such as Figures 1 to 3As shown, the second connector 20 is disposed in the robot 200. A slot structure 211 for the insertion of the first connector 11 is formed on the second connecting portion 21. The second mating surface is located at the bottom of the slot structure 211, and the second conductive terminal 22 protrudes from the second mating surface and is located within the slot structure 211. When the first mating surface and the second mating surface are approximately in contact, the first connecting portion 11 is located within the slot structure 211, and the second conductive terminal 22 is inserted into the insertion slot 10a and mats with the first conductive terminal 12, thereby ensuring the stability of the connection between the first connector 10 and the second connector 20. The wiper 13 can wipe away the liquid remaining on the second conductive terminal 22 when it is inserted into the insertion slot 10a, thus preventing the connection between the second conductive terminal 22 and the first conductive terminal 12 from being interrupted due to liquid. This ensures reliable contact between the second conductive terminal 22 and the first conductive terminal 12, solves the problem of poor contact between the second conductive terminal 22 and the first conductive terminal 12 in humid environments, and also avoids the potential charging hazard caused by water stains during the connection of the connector assembly 100. This greatly improves the service life of the connector assembly 100 and ensures the stability of signal transmission.

[0044] It should be noted that the robot 200 is used in outdoor or underwater environments, such as an underwater robot 200 or an outdoor inspection robot 200. Therefore, the first connector 10 of this application is mainly designed for the electrical connection needs of the robot 200 in outdoor or underwater environments. The wiper 13 is integrated into the insertion slot 10a, requiring no additional space. This miniaturized first connector 10 can solve the contact reliability problem of the connector assembly 100 in humid environments through the wiper 13, ensuring the stability of signal transmission. The second connector 20 can be installed on the robot 200, while the first connector 10 can be installed in other devices besides the robot 200, such as an adapter or charging device. The adapter or charging device can be used with the robot 200 and sold together, or it can be sold separately from the robot 200. These are common selection methods for those skilled in the art, and will not be elaborated further here.

[0045] In one alternative implementation, such as Figures 2 to 6As shown, a recessed insertion groove 10a is formed on the first connecting portion 11. The first conductive terminal 12 is disposed in the insertion groove 10a. The squeegee 13 is disposed at the front end of the first conductive terminal 12 so that when the second conductive terminal 22 is connected to the first conductive terminal 12, the second conductive terminal 22 first contacts the squeegee 13 to remove water stains from the surface of the second conductive terminal 22. This allows the second conductive terminal 22 to enter the insertion groove 10a in a relatively dry state and then make electrical connection with the first conductive terminal 12. This avoids the humid environment in the insertion groove 10a from affecting the conductivity of the first conductive terminal 12 and the second conductive terminal 22, thereby improving the service life of the connector assembly 100 and avoiding safety hazards caused by water stains when the first conductive terminal 12 and the second conductive terminal 22 are connected.

[0046] After adopting the above technical solution, since the first connecting part 11 forms a insertion groove 10a through the recess, the first conductive terminal 12 is embedded in the groove to form a physical protective barrier, which can reduce the direct contact of external water vapor or impurities with the first conductive terminal 12. At the same time, it can also form a dual protection mechanism of first blocking and then scraping with the wiper 13 near the opening side, ensuring that when the second conductive terminal 22 is fully inserted into the insertion groove 10a, the liquid on the second conductive terminal 22 can be scraped off, and preventing the liquid from being brought into the contact area between the first conductive terminal 12 and the second conductive terminal 22. The liquid removal action occurs before the first conductive terminal 12 contacts the second conductive terminal 22, eliminating the risk of liquid contact in terms of timing. That is, when the second conductive terminal 22 is inserted, it passes through the wiper 13 first and then contacts the first conductive terminal 12. At the same time, during the insertion process of the second conductive terminal 22 and the first conductive terminal 12, the wiper 13 can always maintain contact with the second conductive terminal 22 to remove residual liquid on the first conductive terminal 12 in real time without additional operation, ensuring that the surface of the first conductive terminal 12 is dry before and after contact.

[0047] In an optional embodiment, the insertion groove 10a is formed within the first conductive terminal 12, such that the contact surface between the second conductive terminal 22 and the first conductive terminal 12 is completely covered when the second conductive terminal 22 is inserted, thereby increasing the signal or current transmission area. The wiper element 13 is disposed within the first conductive terminal 12 and located on the side of the insertion groove 10a near the opening, forming a timing logic of wiping water upon insertion. This ensures that liquid is completely removed after the second conductive terminal 22 enters the insertion groove 10a, preventing increased contact resistance due to electrolytic corrosion and thus extending the service life of the connector assembly 100.

[0048] For example, the first conductive terminal 12 is sleeve-shaped and disposed on the first connecting portion 11. The insertion groove 10a is formed inside the first conductive terminal 12 and opens to one side facing the first mating surface. The wiper 13 is located on the side of the insertion groove 10a close to the first mating surface, so that when the second conductive terminal 22 is inserted into the insertion groove 10a, the wiper 13 can wipe away the liquid remaining on the second conductive terminal 22, preventing the liquid from being brought into the contact area between the first conductive terminal 12 and the second conductive terminal 22.

[0049] In an alternative embodiment, the side of the insertion groove 10a near the opening is inclined outward so that liquid can be discharged from the insertion groove 10a, so that the liquid removed by the wiper 13 can be automatically discharged along the slope by gravity, thus avoiding liquid accumulation in the groove.

[0050] For example, the insertion groove 10a has an inclined side located on the side of the insertion groove 10a closest to the first mating surface, so that the liquid removed by the wiper 13 can be directly guided to the outside of the insertion groove 10a by the inclined surface of the inclined side, preventing the liquid from accumulating at the opening of the insertion groove 10a and then re-adhering to the second conductive terminal 22. The bottom of the insertion groove 10a can be kept horizontal or inclined in the opposite direction to form a funnel structure that is wider at the outside and narrower at the inside, which facilitates drainage and prevents external liquid from back-entering.

[0051] In an optional embodiment, the wiper element 13 is a ring-shaped component made of a deformable material. The ring-shaped component is fixed to the first connecting portion 11 or the first conductive terminal 12 by assembly, so that after the second conductive terminal 22 is inserted into the insertion groove 10a, the ring-shaped component can use elastic deformation to press against the outside of the second conductive terminal 22, thereby clearing the liquid on the second conductive terminal 22 and guiding it to the outside of the insertion groove 10a, preventing liquid from entering the insertion groove 10a. The deformable material includes, but is not limited to, silicone rubber, fluororubber, or other elastomers, which not only possess elastic properties but also wear-resistant characteristics.

[0052] In an optional embodiment, the annular member is integrally formed with the first connecting portion 11 or the first conductive terminal 12 to eliminate installation errors of the split structure. It can also prevent liquid or particles from penetrating into the gap between the annular member and the first connecting portion 11 or the first conductive terminal 12, ensuring that the annular member will not fall off after multiple insertions and improving reliability.

[0053] In an optional embodiment, the inner diameter of the annular member is smaller than the inner diameter of the insertion groove 10a. The inner diameter of the insertion groove 10a is adapted to the outer diameter of the second conductive terminal 22, so as to achieve the dual functions of dynamic sealing and precise guidance through the interference fit between the second conductive terminal 22 and the annular member, and to ensure that the second conductive terminal 22 can have a long-term seal through repeated insertion and removal from the insertion groove 10a.

[0054] In an optional embodiment, the wiper 13 has a chamfered structure on the side facing the first mating surface to reduce the insertion force of the second conductive terminal 22.

[0055] In one optional embodiment, the number of annular members is at least two, and the at least two annular members are spaced apart on the side of the insertion groove 10a near the opening to form a double-sealed seal, which improves the liquid removal effect and the reliability of the contact between the first conductive terminal 12 and the second conductive terminal 22, and avoids the inability to scrape off the liquid on the second conductive terminal 22 when a single annular member fails, effectively preventing the liquid from entering the insertion groove 10a and causing corrosion to the first conductive terminal 12.

[0056] For example, the annular member includes a first annular member 131 and a second annular member 132, which are spaced apart in the insertion groove 10a, and both the first annular member 131 and the second annular member 132 are located at the front end of the first conductive terminal 12.

[0057] like Figures 1 to 6 As shown, according to a second aspect of this application, this application also provides a connector assembly 100, including a second connector 20 and the aforementioned first connector 10. The second connector 20 includes a second connecting portion 21 and a second conductive terminal 22 for electrical connection with a first conductive terminal 12. The second conductive terminal 22 is disposed on the second connecting portion 21. A squeegee 13 can scrape off the liquid on the second conductive terminal 22 when it is connected to the first conductive terminal 12, avoiding interruption of the connection between the second conductive terminal 22 and the first conductive terminal 12 due to liquid, ensuring reliable contact between the second conductive terminal 22 and the first conductive terminal 12, solving the problem of poor contact between the second conductive terminal 22 and the first conductive terminal 12 in humid environments, and also avoiding the potential charging hazard caused by water stains during connection of the connector assembly 100, greatly improving the service life of the connector assembly 100, and ensuring signal transmission stability.

[0058] In an optional embodiment, the second connecting part 20 is provided with a slot structure 211 for the first connecting part 11 to be inserted. The slot structure 211 is provided with a drain hole 212. The drain hole 212 is used to drain the liquid scraped by the wiper 13, so as to prevent the liquid from accumulating in the slot structure 211 and causing problems such as corrosion of the connector assembly 100, electrical short circuit or mechanical jamming.

[0059] In an optional embodiment, a drain hole 212 is located at the bottom of the slot structure 211 so that when the first connector 10 is connected to the second connector 20, the water scraped by the wiper 13 can be discharged through the drain hole 212 at the bottom of the slot structure 211 and then flow out to the outside. The drain hole 212 is located at the lowest position at the bottom of the slot structure 211 so that drainage can be carried out by gravity. In an optional embodiment, one of the first connecting portion 11 and the second connecting portion 21 is provided with a partition groove 14, and the other of the first connecting portion 11 and the second connecting portion 21 is provided with a partition member 23. The partition member 23 cooperates with the partition groove 14, which not only prevents a short circuit between the second conductive terminal 22 and the first conductive terminal 12 due to the liquid scraped by the wiper 13 during charging, but also guides the connection between the first connecting portion 11 and the second connecting portion 21 to ensure precise contact between the wiper 13 and the second conductive terminal 22 during docking, avoiding mechanical damage.

[0060] In an optional embodiment, the partition groove 14 is formed between two adjacent first conductive terminals 12 or two adjacent second conductive terminals 22, which can separate the two adjacent first conductive terminals 12 or two adjacent second conductive terminals 22 to prevent short circuits between the second conductive terminals 22 and the first conductive terminals 12 due to the liquid scraped off by the wiper 13 during charging.

[0061] In an optional embodiment, a separator 23 is disposed between two adjacent slot structures 211 to separate the two adjacent slot structures 211. At least two slot structures 211 have different shapes, which serves as a mechanical foolproof mechanism to prevent the user from reversing the polarity of the first connector 10 and the second connector 20 when using the connector assembly 100.

[0062] For example, there are two slot structures 211, and a separator 23 is disposed between the two slot structures 211. The two slot structures 211 have different shapes.

[0063] In an alternative embodiment, the separator 23 and the second conductive terminal 22 are integrally formed to simplify the structure of the second connector 20 and enable the second connector 20 to function as a guide structure for mating with the insertion slot 10a.

[0064] In an optional embodiment, the distance between the partition groove 14 and the first mating surface is less than the distance between the wiper 13 and the first mating surface, so that the second conductive terminal 22 can be inserted into the insertion groove 10a after the partition 23 cooperates with the partition groove 14, and the wiper 13 scrapes the liquid off the second conductive terminal 22 after the second conductive terminal 22 is inserted into the insertion groove 10a.

[0065] In one alternative implementation, such as Figure 3 , Figure 7 and Figure 8 As shown, the second connector 20 also includes a sealing cap 24, which is detachably mounted on the open end of the slot structure 211 to close the slot structure 211 and reduce the contact between external liquid and the second conductive terminal 22 inside the slot structure 211.

[0066] In an alternative embodiment, the sealing cap 24 is made of a flexible material to seal the slot structure 211 by compression, preventing the slot structure 211 from falling off due to vibration and ensuring the stability of the connection between the sealing cap 24 and the slot structure 211.

[0067] In an optional embodiment, the sealing cover 24 includes a cover body 241, a sealing plug 242, and a connector 243. The cover body 241 is connected to the second connecting part 20 or the robot 200 via the connector 243. The sealing plug 242 is disposed on the cover body 241 and is used to cooperate with the slot structure 211, so that the sealing plug 242 can be accommodated within the slot structure 211 to achieve a seal on the slot structure 211. The sealing plug 242 is provided with a terminal hole 2421 so that the second conductive terminal 22 can be accommodated within the terminal hole 2421.

[0068] In one optional embodiment, the number of slot structures 211 is at least two, with a separator 23 formed between adjacent slot structures 211, and each second conductive terminal 22 is correspondingly disposed within each slot structure 211. The number of sealing plugs 242 is adapted to the number of slot structures 211, and adjacent sealing plugs 242 are spaced apart with a gap, the size of which is adapted to the size of the separator 23, so that each sealing plug 242 can be inserted into each slot structure 211, thereby sealing each slot structure 211.
