[0034] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0036] Connectors, as accessories used in electronic devices to achieve electrical connections, are widely used in fields such as communications, automotive, industrial automation, aerospace, medical, and consumer electronics. In outdoor work scenarios, the waterproofness of connectors directly affects the operational status of electronic devices. For example, when drones are used for outdoor operations, especially for spraying pesticides or irrigation, connectors must ensure that conductive liquids such as pesticides and water do not seep into the connector and cause short circuits in the drone.

[0037] In response, this utility model provides a connector 1000 for use in an electronic device 2000. Please refer to [link / reference]. Figures 1 to 6The connector 1000 includes a connection component 1 and a sleeve 2. The sleeve 2 covers the outer surface of the connection component 1 to significantly reduce the area of ​​the connection component 1 that communicates with the external environment, thereby reducing the risk of external conductive liquids immersing the connection component 1. Specifically, the connecting component 1 includes a first frame 11 and a second frame 12 connected to each other. The first frame 11 is used to connect an external cable A, and the second frame 12 is used to connect an external device. The sleeve 2 is provided with a receiving cavity 21, a first port 22, and a second port 23. Both the first port 22 and the second port 23 are connected to the receiving cavity 21. The first port 22 is used for the external cable A to extend into the receiving cavity 21, and then the external cable A is connected to the first frame 11, thereby realizing the conduction between the external cable A and the connecting component 1. The second port 23 is used for the second frame 12 to partially extend out of the receiving cavity 21, so that the second frame 12 can connect to the external device. The external cable A is connected to the external device through the connected first frame 11 and the second frame 12, so as to facilitate the transmission of current. Furthermore, through the above-mentioned setting of the sleeve 2, the connecting component 1 is prevented from being directly exposed to the external environment, thereby reducing the impact of external conductive liquids on the connector 1000 and improving the waterproof performance of the connector 1000.

[0038] It should be noted that the first frame 11 and the second frame 12 are manufactured as a single piece, which gives the first frame 11 and the second frame 12 high structural strength. Compared with the method of manufacturing the first frame 11 and the second frame 12 separately and then welding them together, the structure is simpler and the manufacturing efficiency is improved.

[0039] It is understood that the first frame 11 can be connected to the external cable A in ways including but not limited to: screwing, crimping, welding, and wire winding. For example, in this embodiment, the first frame 11 is crimped.

[0040] For details, please refer to Figure 1 and Figure 4 The first frame 11 includes a connecting part 111 and a holding part 112. The holding part 112 is disposed on both sides of the connecting part 111, and the connecting part 111 and the holding part 112 together form a plug cavity 113. When the external cable A is placed in the plug cavity 113, the holding part 112 is squeezed by wire clamps to produce plastic deformation, thereby holding the external cable A and realizing the connection between the first frame 11 and the external cable A.

[0041] It should be noted that the shape of the pressing part 112 includes, but is not limited to, sheet type, cylindrical type, etc. (See attached image) Figure 1 The pressing part 112 shown is a sheet type, and two sheet-type pressing parts 112 are provided on both sides of the connecting part 111; as shown in the attached figure. Figure 4 The pressure holding part 112 shown is cylindrical.

[0042] It is understood that the second frame 12 can be connected to external devices in ways including but not limited to: screw connection, crimping, welding, and wire routing. For example, in this embodiment, the second frame 12 is connected by screws.

[0043] For details, please refer to Figure 1 and Figure 3 The connection component 1 includes a screw connector 13 and a connector 14. The connector 14 is used to connect to an external device. One end of the connector 14 is connected to the motherboard of the external device, and the other end of the connector 14 is connected to the second frame 12. This allows the current of the external cable A to be transmitted to the external device after passing through the first frame 11, the second frame 12, and the connector 14 in sequence. Furthermore, the connector 14 is provided with a first screw hole 141. The second frame 12 is provided with a first through hole 121. The screw connector 13 passes through the first through hole 121 and is screwed into the first screw hole 141. The second frame 12 is connected to the external device by screwing. The connection strength is higher than that of the snap-fit ​​or crimping method, and the connection stability is stronger. Moreover, the structure of the screw connector 13 and the connector 14 makes the connector 1000 and the external device form a detachable connection, which facilitates the disassembly, assembly, and maintenance of the connector 1000.

[0044] For further details, please refer to Figure 1 and Figure 3 In order to improve the connection strength between the screw connector 13 and the connector 14, in some embodiments, the connecting assembly 1 further includes a washer 15. The washer 15 is placed between the screw connector 13 and the second frame 12 to increase the friction between the screw connector 13 and the second frame 12, prevent the screw connection between the screw connector 13 and the connector 14 from loosening due to external vibration, and the washer 15 can also disperse the force applied by the screw connector 13 to the second frame 12, protect the second frame 12 and prevent deformation.

[0045] In some embodiments, please refer to Figure 1 and Figure 3The second frame 12 extends toward the connector 14 and has multiple flow-through walls 122, which surround the first through hole 121. When the connector 14 is screwed to the second frame 12 by the screw 13, the multiple flow-through walls 122 fit against the sidewalls of the connector 14, thereby increasing the contact area between the connector 14 and the second frame 12, and thus improving the current-carrying capacity of the connector 1000. According to Ohm's law: I = U / R (where I is current, U is voltage, and R is resistance), when the voltage is constant, the smaller the resistance, the larger the current that can pass through. Furthermore, combined with the law of resistance: R = ρ*(l / S) (where ρ is resistivity, l is conductor length, and S is conductor cross-sectional area), when resistivity and length are constant, increasing the contact area reduces the resistance. In this embodiment, the cooperation between the current-passing wall 122 and the connector 14 increases the contact area between the second frame 12 and the connector 14, thereby increasing the cross-sectional area through which current passes, reducing the resistance, and thus improving the current-passing capacity of the connector 1000.

[0046] Furthermore, the sleeve 2 is provided with a second through hole 24, which corresponds to the first through hole 121, so that the user can disassemble and assemble the screw connector 13 through the second through hole 24, thereby improving the installation efficiency of the connector 1000. The sleeve 2 includes a first rubber plug 25, which covers the second through hole 24. By providing the first rubber plug 25, the second through hole 24 is covered, thereby sealing the receiving cavity 21 and preventing external conductive liquids from entering the receiving cavity 21 through the second through hole 24 and affecting the waterproof performance of the sleeve 2.

[0047] It should be noted that, in order to prevent the first rubber plug 25 from being lost during frequent disassembly and assembly of the connector 1000, in some embodiments, the first rubber plug 25 is provided with a hanging rope 251, the hanging rope 251 is sleeved on the rubber sleeve 2, and the outer wall of the rubber sleeve 2 is provided with a rope groove, and the hanging rope 251 is sleeved in the rope groove.

[0048] Understandably, in order to facilitate the processing of the first rubber stopper 25, the first rubber stopper 25 and the hanging rope 251 are integrally injection molded, and in order to ensure the sealing of the connection between the first rubber stopper 25 and the rubber sleeve 2, the first rubber stopper 25 can undergo elastic deformation.

[0049] It should be noted that, in order to further enhance the ability of the screw connector 13 to resist external vibration, after the connector 1000 is assembled, the end of the first rubber plug 25 near the receiving cavity 21 presses the screw connector 13, thereby applying an axial abutment force to the screw connector 13 to prevent loosening.

[0050] In some embodiments, please refer to Figure 1 and Figure 3The sleeve 2 includes a second rubber plug 26, which covers at least a portion of the second frame 12. A portion of the second rubber plug 26 extends into the receiving cavity 21 from the second port 23. One end of the second rubber plug 26 abuts against the inner wall of the receiving cavity 21, while the other end abuts against the housing of the external device, sealing the gap between the second rubber plug 26 and the housing. This allows the connector 1000 to seal the gap between the second rubber plug 26 and the housing when connected to an external device, preventing conductive liquids from entering the receiving cavity 21 through the gap and further improving the waterproofness of the connector 1000.

[0051] It is understood that the second rubber stopper 26 may be inserted into the receiving cavity 21 in ways including but not limited to: a protrusion engaging with a groove, an internal thread engaging with an external thread, or an interference fit. For example, in this embodiment, a protrusion engaging with a groove structure is used.

[0052] For details, please refer to Figure 3 and Figure 6 The outer wall ring of the second rubber plug 26 is provided with a locking protrusion 261; the inner wall ring of the second port 23 is provided with a locking groove 231, and the locking protrusion 261 is accommodated in the locking groove 231. Through the cooperation of the locking protrusion 261 and the locking groove 231, a detachable quick-release structure is realized between the second rubber plug 26 and the rubber sleeve 2, which improves the installation efficiency of the second rubber plug 26. In addition, the locking groove 231 also realizes the limiting function of the locking protrusion 261, preventing the length of the second rubber plug 26 extending into the receiving cavity 21 from exceeding the preset distance, which would affect the cooperation between the second rubber plug 26 and the housing of the external device, and serves as a reminder to the user.

[0053] It is understood that the aforementioned rubber sleeve 2, first rubber plug 25, hanging rope 251, and second rubber plug 26 are all designed for waterproofing, and therefore all need to be made of materials with elastic deformation capabilities, including but not limited to: rubber, silicone, plastic, and any combination of one or more of these materials. For example, in this embodiment, the rubber sleeve 2 is made of plastic, and the first rubber plug 25, hanging rope 251, and second rubber plug 26 are all made of silicone.

[0054] It should be noted that the first frame 11 and the second frame 12 are the main components connecting the external cable A and the external equipment. In the actual installation process, the installation angle and installation space between the external cable A and the external equipment are limited. In order to save space and facilitate the installation of the connector 1000, the first frame 11 and the second frame 12 need to be set at an angle, thereby forming various styles of connector 1000.

[0055] It is understandable that the angle between the first frame 11 and the second frame 12 includes, but is not limited to, a straight angle, a right angle, an acute angle, an obtuse angle, etc.

[0056] In some embodiments, please refer to Figure 4 The first frame 11 and the second frame 12 are perpendicular. Depending on the connection method between the first frame 11 and the external cable A, and the connection method between the second frame 12 and the external device, various installation angles can be formed between the external cable A and the external device. For example, in this embodiment, the connection method between the first frame 11 and the external cable A is preferably crimped, and the connection method between the second frame 12 and the external device is preferably screwed. Since the first frame 11 and the second frame 12 are perpendicular, the connection direction between the external cable A and the external device is parallel. Alternatively, when the connection method between the first frame 11 and the external cable A is preferably crimped, and the connection method between the second frame 12 and the external device is preferably crimped, the connection direction between the external cable A and the external device is perpendicular because the first frame 11 and the second frame 12 are perpendicular. Specific combinations are selected according to actual needs, and will not be illustrated here.

[0057] In other embodiments, please refer to Figure 1 The first frame 11 and the second frame 12 are parallel. Depending on the connection method between the first frame 11 and the external cable A, and the connection method between the second frame 12 and the external device, various installation angles can be formed for the external cable A and the external device. For example, in this embodiment, the connection method between the first frame 11 and the external cable A is preferably crimped, and the connection method between the second frame 12 and the external device is preferably screwed. Since the first frame 11 and the second frame 12 are parallel, the connection directions of the external cable A and the external device are perpendicular to each other. Alternatively, when the connection method between the first frame 11 and the external cable A is preferably crimped, and the connection method between the second frame 12 and the external device is preferably crimped, since the first frame 11 and the second frame 12 are perpendicular, the connection directions of the external cable A and the external device are parallel. Specific combinations are selected according to actual needs, and will not be illustrated here.

[0058] It should be noted that when the included angle between the first frame and the second frame is different, the shape of the rubber sleeve also needs to be adapted, which will not be elaborated here.

[0059] In this embodiment, the connector 1000 includes a connecting component 1 and a sleeve 2. The connecting component 1 includes a first frame 11 and a second frame 12 connected to each other. The first frame 11 is used to connect an external cable A, and the second frame 12 is used to connect an external device. The sleeve 2 is provided with a receiving cavity 21, a first port 22, and a second port 23. Both the first port 22 and the second port 23 are connected to the receiving cavity 21. The first port 22 is used for the external cable A to extend into the receiving cavity 21, and then the external cable A is connected to the first frame 11, thereby realizing the conduction between the external cable A and the connecting component 1. The second port 23 is used for the second frame 12 to partially extend out of the receiving cavity 21, so that the second frame 12 can connect to the external device. The external cable A is connected to the external device through the connected first frame 11 and the second frame 12, so as to facilitate the transmission of current. Furthermore, by setting the sleeve 2 as described above, the connecting component 1 is prevented from being directly exposed to the external environment, thereby reducing the impact of external conductive liquids on the connector 1000 and improving the waterproof performance of the connector 1000.

[0060] This utility model also provides an embodiment of an electronic device 2000, please refer to [link / reference]. Figure 7 and Figure 8 The electronic device 2000 includes a cable A, a device body B, and the aforementioned connector 1000. One end of the connector 1000 is connected to the cable A, and the other end of the connector 1000 is connected to the device body B.

[0061] Understandably, in actual electronic devices 2000, the number of connectors 1000 required is not limited to one. The more complex the electronic device 2000, the more connectors 1000 are needed to meet the power supply requirements of the electronic device 2000.

[0062] It should be noted that for the specific structure and function of connector 1000, please refer to the above embodiments, which will not be repeated here.

[0063] In some embodiments, the electronic device 2000 further includes a limiting cover C; the limiting cover C is disposed on the device body B and covers the connector 1000, and the limiting cover C presses against the connector 1000. By pressing against the connector 1000 with the limiting cover C, the loosening and detachment of the connection between the connector 1000 and the device body B caused by vibrations during the operation of the electronic device 2000 is reduced, enhancing the connection stability between the connector 1000 and the device body B. Furthermore, since the limiting cover C covers the connector 1000, it also protects the connector 1000, reducing the probability of foreign objects such as external conductive liquids entering the connector 1000. Moreover, the pressing against the connector 1000 with the limiting cover C reduces the risk of the first rubber plug 25 detaching due to external vibration, ensuring the waterproofness of the connector 1000.

[0064] It is understood that the limiting cover C can be disposed on the device body B in ways including but not limited to: screwing, snap-fitting, gluing, welding, etc. For example, in this embodiment, the electronic device 2000 includes multiple screw caps, and the limiting cover C is screwed to the device body B.

[0065] Specifically, please refer to the figure. The limit cover C is provided with multiple screw-in through holes C1, and the main body B of the equipment is provided with multiple docking screw holes B1. A screw tip passes through a screw-in through hole C1 and is screwed into a docking screw hole B1 to screw the limit cover C to the main body B of the equipment.

[0066] Furthermore, in order to enhance the connection stability between the limiting cover C, the connector 1000, and the device body B, the outer wall of the rubber sleeve 2 extends into an extension portion. The extension portion is provided with a through hole. A screw tip passes through a screw connection through hole C1 and the through hole in sequence and is screwed into a mating screw hole B1, thereby improving the connection strength between the limiting cover C, the connector 1000, and the device body B.

[0067] It should be noted that the aforementioned electronic device 2000 can be any device that can be powered by the connector 1000, including but not limited to: drones, generators, power tools, fans, etc. It should also be noted that the preferred embodiments of this utility model are given in the specification and accompanying drawings; however, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to impose additional limitations on the content of this utility model, but are provided to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
