DETAILED DESCRIPTION

[0031] ​In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] In the description of the present application, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] In the present application, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0034] The floating connector allows the connector to absorb a certain position deviation and error during plugging by designing a floating structure inside the connector or carrying elastic elements and mechanical structures, and at the same time can absorb the vibration energy of the working process of the buffer device by using the floating function, which plays a key protection role for the connector. The floating connector is widely used in many fields, including industry and instrumentation, automobiles, consumer electronics and medical devices, etc., to ensure the stability of current transmission and data transmission in complex environments. As in the existing unmanned aerial vehicle, the floating connector is usually used to connect the battery and the main body of the aircraft. Since the battery often needs to be pulled out to connect the charger for charging, when pulled out, the contact terminals in the connector of the main body of the aircraft will be exposed. It is inevitable that splashed water and dust will easily adhere to the surface of the contact terminals, which not only may cause the contact terminals to be contaminated, thereby affecting their normal contact, but also in extreme cases, may cause short circuit problem, causing serious safety hazard.

[0035] In order to overcome the above technical problems, with reference to Figures 1-9 The embodiment provides a floating connector, which comprises:

[0036] The shell 1 is provided with a terminal mounting cavity 111;

[0037] The terminal group 2 is mounted in the terminal mounting cavity 111;

[0038] The protective cover assembly 3 is mounted on the shell 1 in an openable and closable manner, and can cover the insertion port of the terminal mounting cavity 111 to provide protection for the internal terminal group 2.

[0039] The shell 1 is the main structure of the connector, and the shell 1 is designed with a terminal mounting cavity 111 for accommodating and fixing the terminal group 2. The material and structure of the shell 1 need to have certain strength, durability and insulation to ensure the stable operation of the connector in complex environments. At the same time, the shell 1 is generally designed with a mounting structure cooperating with the protective cover assembly 3 to realize the openable and closable mounting of the protective cover assembly 3.

[0040] The terminal group 2 is the core component of the connector, responsible for the transmission of current and the exchange of data. The terminal group 2 is mounted in the terminal mounting cavity 111 of the shell 1, and when the insertion terminal of the external connector is inserted from the insertion port of the terminal mounting cavity 111, the insertion terminal will contact the internal terminal group 2, thereby establishing a conduction path. The terminal group 2 is generally provided with positive and negative terminals, and in some cases, signal terminals are also provided, and the structure and number of the terminal mounting cavity 111 need to be correspondingly set according to the structure and number of the terminal group 2.

[0041] The protective cover assembly 3 is a component that can be mounted on the shell 1 in an openable and closable manner, and its main function is to cover the insertion port of the terminal mounting cavity 111 to provide protection for the internal terminal group 2. The design of the protective cover assembly 3 needs to consider factors such as sealing, durability and ease of operation to ensure that in complex environments such as unmanned aerial vehicles, it can effectively prevent moisture, dust and other pollutants from entering the interior of the connector, while facilitating the user's plugging operation.

[0042] In summary, based on the floating connector of the present embodiment, the terminal group 2 is mounted in the terminal mounting cavity 111 of the shell 1, and the protective cover assembly 3 capable of covering the insertion port of the terminal mounting cavity 111 is provided on the shell 1, so that in the case where the floating connector is not connected with the external connector, the protective cover assembly 3 can close the insertion port, thereby effectively preventing moisture, dust and other pollutants from entering the interior of the connector, avoiding the problem that the contact terminal is contaminated and affects normal contact, and also reducing the risk of short circuit, improving the safety and reliability of the connector.

[0043] In one embodiment, in combination with Figure 8 and Figure 9The protective cover assembly 3 comprises a flip cover plate 31 and an elastic return member 32. The flip cover plate 31 is rotatably installed on the housing 1. The elastic return member 32 is connected to the flip cover plate 31 and can drive the flip cover plate 31 to automatically rotate and close.

[0044] The flip cover plate 31 is rotatably installed on the housing 1 by a specific rotating mechanism (such as a hinge, a rotating shaft 312, etc.). This installation method allows the flip cover plate 31 to rotate around a fixed axis within a certain range, thereby realizing the opening and closing operation of the insertion port of the terminal mounting cavity 111. The edge of the flip cover plate 31 can be designed with a sealing ring or a sealing strip to enhance the sealing between the flip cover plate 31 and the housing 1, preventing moisture, dust, and other pollutants from entering the connector.

[0045] The elastic return member 32 (such as a spring, a torsion spring, etc.) is connected to the flip cover plate 31 and provides the driving force required for rotating and closing. When the flip cover plate 31 is opened, the elastic return member 32 is stretched or twisted and stores energy. When the external force disappears, the elastic return member 32 releases the energy and drives the flip cover plate 31 to automatically rotate and close. One end of the elastic return member 32 is usually fixed on the housing 1 or a fixed member, and the other end is connected to the flip cover plate 31. This connection method ensures that the elastic return member 32 can stably provide driving force and allows the flip cover plate 31 to be easily opened and closed when needed.

[0046] This scheme adopts the automatic rotating and closing function to ensure that the flip cover plate 31 can be closed in time, preventing moisture, dust, and other pollutants from entering the connector, thereby protecting the internal terminal group 2 from pollution and damage. The rotatable installation of the flip cover plate 31 allows users to easily open and close the protective cover assembly 3, facilitating the plugging and unplugging operations and maintenance work of the connector.

[0047] In an embodiment, the opening direction of the flip cover plate 31 is that when the insertion terminals of an external connector are inserted into the terminal mounting cavity 111, they can push the flip cover plate 31 to turn inward and open.

[0048] When the insertion terminals of an external connector contact the flip cover plate 31, they will exert an inward pushing force, causing the flip cover plate 31 to turn inward around its rotating axis. This eliminates the need for users to manually open the flip cover plate 31, making the insertion process more convenient and efficient. At the same time, the inwardly turned flip cover plate 31 does not occupy space outside the connector, which is particularly important for space-limited application scenarios.

[0049] In an embodiment, the protective cover assembly 3 further comprises a mounting frame 33. The mounting frame 33 is installed on the housing 1 and surrounds the insertion port of the mounting cavity. The mounting frame 33 restricts the flip cover plate 31 on the housing 1, so that the flip cover plate 31 can only turn inward and open.

[0050] The mounting frame 33 is tightly connected with the shell 1 by a specific fixing method (such as screws, buckles, etc.), forming a stable frame for supporting and positioning the flip cover 31. The design of the mounting frame 33 cleverly limits the movement range of the flip cover 31, ensuring that the flip cover 31 can only be flipped inward to open. This limitation not only prevents the flip cover 31 from accidentally opening or falling off under uncontrolled conditions, but also ensures that the insertion terminal can smoothly push the flip cover 31 into the open state. In addition, the tight fit between the mounting frame 33 and the shell 1 helps to improve the overall sealing of the connector. When the flip cover 31 is in the closed state, the mounting frame 33 can act as an additional barrier to prevent moisture, dust, and other contaminants from seeping in through the gap.

[0051] In an embodiment, referring to Figure 7 , the shell 1 is provided with a square frame 112 arranged around the insertion port of the mounting cavity, and the protective cover assembly 3 is mounted on the square frame 112.

[0052] The square frame 112 is preferably an integral structure formed on the shell 1, which forms a regular rectangular or square area around the insertion port, providing precise positioning and support for the installation of the protective cover assembly 3. The protective cover assembly 3 can be correspondingly arranged in a square structure, which is more conducive to the stable installation of the flip cover 31 compared to a circular structure, and also helps to improve the sealing performance in the closed state.

[0053] In an embodiment, the elastic return member 32 is a torsional spring, which includes a first torsional arm and a second torsional arm; the flip cover 31 includes a cover body 311 and a rotating shaft 312, and the torsional spring is sleeved on the rotating shaft 312, with the first torsional arm abutting against the flip cover 31 body and the second torsional arm abutting against the square frame 112, thereby realizing the automatic rotation and closing of the flip cover 31 driven by the elastic return member 32.

[0054] When the insertion terminal of the external connector pushes the flip cover 31 to flip inward, the flip cover 31 body will cause the first torsional arm to twist relative to the second torsional arm, at which time the torsional spring stores elastic potential energy; after the insertion terminal is pulled out, the torsional spring releases the stored potential energy, driving the first and second torsional arms to return to the initial position, thereby automatically rotating and closing the flip cover 31.

[0055] In this embodiment, the use of a torsional spring has stable elasticity and reset ability, which can ensure that the flip cover 31 accurately returns to the closed position after each use, which helps to maintain the sealing and protective performance of the connector. At the same time, the structure of the torsional spring is relatively simple, easy to manufacture and install, and its working principle is relatively stable and reliable, capable of maintaining stable performance under various environmental conditions.

[0056] In an embodiment, in combination withFigures 1-3 Further comprising a mounting plate 4, the mounting plate 4 is provided with a spring seat 41, and a connecting column is arranged in the spring seat 41; the shell 1 is provided with a mounting arm 113, and a floating spring 5 is arranged between the mounting arm 113 and the spring seat 41, and a gasket 51 is arranged on the side of the mounting arm 113 away from the spring seat 41, and a mounting bolt 52 passes through the gasket 51 and is locked to the connecting column, so that the mounting arm 113 presses the floating spring 5.

[0057] In this embodiment, the mounting plate 4 is the structure of the specific product when the floating connector of the embodiment is applied, for example, when the floating connector of the embodiment is applied to a drone, the mounting plate 4 is the structure on the drone, and the shell 1 is mounted on the mounting plate 4, which is equivalent to mounting the floating connector of the embodiment on the drone.

[0058] In the specific structure of this embodiment, the mounting plate 4 is provided with a spring seat 41, and a connecting column is further arranged in the spring seat 41, which allows the floating spring 5 to be stably mounted on the spring seat 41 and connected to the mounting arm 113 through the connecting column. The accurate position and size design of the spring seat 41 and the connecting column ensures that the floating spring 5 can correctly function. The mounting bolt 52 passes through the gasket 51 and is locked to the connecting column, so as to press the mounting arm 113 on the floating spring 5. This fastening method ensures the stability and reliability of the floating connector on the mounting plate 4; at the same time, by adjusting the fastening degree of the mounting bolt 52, the compression amount of the floating spring 5 can also be adjusted to a certain extent, so as to realize the fine adjustment of the floating range of the floating connector.

[0059] The design of the floating spring 5 can compensate for the tolerances and errors generated during the installation and use of the connector, which helps to ensure the performance and reliability of the connector under different conditions. At the same time, the elastic properties of the floating spring 5 enable the connector to resist external vibration and impact, which helps to protect the electrical connections and mechanical structures inside the connector from damage.

[0060] In an embodiment, in combination with Figure 6 The side of the mounting arm 113 close to the floating spring 5 is provided with a spring groove 1131 corresponding to the outer diameter of the floating spring 5, and the floating spring 5 is embedded in the spring groove 1131.

[0061] The design of the spring groove 1131 enables the floating spring 5 to be more stably connected to the mounting arm 113, avoiding displacement or falling off of the floating spring 5, thereby improving the stability of the entire floating connector.

[0062] In one embodiment, the housing 1 includes a main shell 11 and a shell tail cover 12, the terminal mounting cavity 111 is provided in the main shell 11, and the two ends of the terminal mounting cavity 111 are respectively an insertion port and a mounting port, the insertion port is suitable for the insertion of the insertion terminals of an external connector, and the mounting port is suitable for the installation of the terminal set 2 in the terminal mounting cavity 111; the shell tail cover 12 is installed at the tail of the main shell 11 to limit the terminal set 2 in the terminal mounting cavity 111.

[0063] The shell tail cover 12 is installed at the tail of the main shell 11, and its main function is to limit the position of the terminal set 2 in the terminal mounting cavity 111, preventing it from loosening or falling off during use. The design of the shell tail cover 12 is usually closely matched with the main shell 11 to ensure that there is no gap or gap between the two, thereby improving the sealing and protection performance of the connector. During the product assembly stage, the terminal set 2 can be installed in the main shell 11 from the mounting port, and then the shell tail cover 12 is installed and fixed to the tail of the main shell 11 to fix the terminal set 2.

[0064] The design of the shell tail cover 12 makes the assembly and maintenance of the connector more convenient, and the user can access the terminal mounting cavity 111 by simply disassembling the shell tail cover 12 and perform necessary maintenance or replacement work.

[0065] In one embodiment, the side of the main shell 11 opposite to the shell tail cover 12 is provided with a plug-in guide column or a plug-in guide hole 114, and the plug-in guide column is suitable for cooperating with the plug-in guide hole 114 or the plug-in guide column of an external connector.

[0066] The design of the plug-in guide column / plug-in guide hole 114 enables the connector to be accurately positioned and aligned during plugging, thereby improving the precision and reliability of plugging. The close cooperation of the plug-in guide column and the plug-in guide hole 114 enhances the connection strength between the floating connector and the external device, so that the floating connector can maintain the stability of its connection state when subjected to external load.

[0067] In one embodiment, a foolproof structure is further provided on the main shell 11.

[0068] The foolproof structure provided on the main shell 11 can prevent the connector from being damaged, the performance from being degraded, or the safety hazard from being caused during the plug-in process due to incorrect operation or installation.
