DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0027] like Figure 1-Figure 3 As shown, a telescopic battery cell matching connector comprises: a main body shell, wherein a first telescopic guide rail 1 and a second telescopic guide rail 2 are respectively arranged on the left and right sides inside the main body shell, for maintaining a stable guiding effect during the extension and retraction of the connector; a spring buffer device 3 is arranged on the right side of the first telescopic guide rail 1, for shock absorption and buffering the impact force during connection; a conductive contact 7 is arranged at the central position inside the connector; dustproof sealing rings are arranged on the top and bottom between the first telescopic guide rail 1 and the main body shell; an adjustable locking device 4 is arranged on the left side of the second telescopic guide rail 2, for adjusting the locking force of the connector; a magnetic positioning device 5 is arranged below the adjustable locking device 4, for positioning the telescopic distance of the telescope; a heat sink 6 is arranged on the top of the connector, for adjusting the working state of the connector.

[0028] In a specific embodiment, when two electronic devices need to be connected, the user inserts the retractable battery cell matching connector into the interface between the devices. The double-track design of the telescopic guide ensures the smooth extension and retraction of the connector, and the user does not need to worry about stuck or unstable connections. When the connector is inserted into the interface, the spring buffer device 3 plays a role, shock-absorbing and buffering the impact force during connection, protecting the interface between the connector and the electronic device, while improving the durability of the connector and extending its service life. The conductive contacts inside the connector ensure the stable transmission of current. Highly conductive materials and surface plating treatments reduce contact resistance and ensure the stability and reliability of power transmission. The dustproof sealing ring at the telescopic part of the connector effectively prevents dust and foreign matter from entering the connector, protects the internal structure from contamination, and extends the service life of the connector.

[0029] After the connection is completed, the adjustable locking device 4 can flexibly adjust the locking force according to the actual situation to ensure the stability of the connection and enhance the stability and reliability of the connector. The magnetic positioning device inside the connector can accurately locate the position of the connector, ensure the accuracy and stability of the connector during the extension and retraction process, and avoid poor connection or damage caused by the displacement of the connector position. The heat sink inside the connector can monitor the temperature of the connector and adjust the working state in time to ensure the stability and reliability of the connector in harsh environments and prevent damage or failure due to overheating.

[0030] When the connector is inserted into the interface, the conductive contact 7 is connected to the electrical contact on the interface to form a path. The current is transmitted from one device to another through the conductive contact 7 to achieve electrical connection. The dustproof sealing ring at the telescopic part of the connector not only protects the internal structure from the invasion of dust and foreign matter, but also ensures the cleanliness and stability of the electrical connection components. The existence of the dustproof sealing ring can reduce faults such as poor contact or short circuit caused by dust pollution, and ensure the reliability of electrical transmission. After the connector is inserted into the interface, the adjustable locking device can adjust the locking force between the connector and the interface. This locking force not only ensures the firmness of the connection, but also provides a stable electrical contact pressure to prevent the loosening or disconnection of the electrical connection, and ensure the stability and reliability of electrical transmission. In addition, the magnetic positioning device 5 inside the connector can accurately locate the position of the connector. This precise positioning ensures the accuracy and stability of the electrical contact between the connector and the interface, prevents faults such as poor contact or short circuit caused by the displacement of the connection position, and ensures the accuracy and reliability of electrical transmission.

[0031] In the above embodiment, the spring buffer device 3 includes a helical spring, a buffer gasket and a fixing bracket; the buffer gasket is located at both ends of the spring and contacts the spring and the movable part respectively.

[0032] In a specific embodiment, the buffer gasket is located at both ends of the spring and contacts the spring and the movable part. The buffer gasket is used to provide a buffer and shock absorption effect when the movable part of the connector moves, so as to prevent the impact force generated by sudden impact or rapid movement from being transmitted to other parts. The fixing bracket is used to fix the spring and the buffer gasket to ensure their correct position in the connector and enable them to function effectively.

[0033] When the connector's moving parts are moved by external force or pressure, the helical spring will be compressed or stretched, providing corresponding elastic support force according to the magnitude and direction of the applied force. At the same time, the buffer gasket provides buffering and shock absorption when the moving parts move, preventing the moving parts from being damaged or generating unnecessary vibrations due to sudden impact or rapid movement.

[0034] The presence of the buffer gasket can effectively reduce the impact and vibration generated when the movable parts of the connector move, and protect the internal structure and electronic components of the connector from damage. In addition, the spring buffer device can provide a stable elastic support force to ensure the stability and reliability of the connector during the connection process, and avoid instability caused by changes in the external environment or movement of the connecting parts. Secondly, the impact and vibration of the internal structure and electronic components of the connector are reduced, which can extend the service life of the connector and improve its reliability and durability.

[0035] In the above embodiment, the conductive contact 7 is made of copper alloy, and the conductive contact 7 is covered with a platinum alloy coating; and an elastic connecting wire is provided below the conductive contact 7 .

[0036] In a specific embodiment, the conductive contact 7 is made of copper alloy, which has good electrical conductivity and mechanical strength and is suitable for conductive parts in connectors. In addition, the conductive contact 7 is covered with a platinum alloy coating, which has excellent corrosion resistance and electrical conductivity, and can improve the stability and durability of the contact. An elastic connecting wire is provided below the conductive contact 7. This design can establish a reliable electrical connection between the conductive contact and the circuit board or other connector accessories, and under the plug-in and unplugging of the connector or the action of external pressure, the elastic connecting wire can effectively buffer pressure and vibration, and protect the stability of the conductive contact and the connector. In addition, since the conductive contact 7 is made of copper alloy and covered with a platinum alloy coating, it has excellent electrical conductivity, which can ensure the stable and reliable transmission of electrical signals or electrical energy in the connector, reduce signal loss and resistance during transmission, and improve the performance of the connector. Secondly, the platinum alloy coating can provide additional corrosion protection, extend the service life of the conductive contact, and reduce connection problems or failures caused by corrosion, thereby improving the reliability and stability of the connector. In a specific implementation, the conductive contact 7 establishes a stable and reliable electrical connection with other connector accessories through an elastic connecting wire, ensuring the transmission quality of the electrical signal or electrical energy in the connector. In addition, the conductive contacts are made of copper alloy and covered with platinum alloy plating, which has good wear resistance and corrosion resistance, so it has a long service life, reduces the failure rate of the connector due to contact damage, and improves the reliability of the connector. Secondly, the excellent conductivity and stable connection of the conductive contacts ensure the stable transmission of electrical signals or electrical energy, reduce signal loss and interference during transmission, and improve the transmission efficiency and performance of the connector.

[0037] In the above embodiment, the dustproof sealing ring is composed of a fluororubber sealing ring; the dustproof sealing ring adopts a double-layer sealing structure, and the double-layer sealing structure includes an outer sealing grid structure and an inner sealing ring structure.

[0038] In a specific embodiment, the dustproof sealing ring is made of fluororubber material, which has good high temperature resistance, chemical resistance and aging resistance, and can effectively prevent external environmental factors such as dust and water vapor from entering the interior of the connector, protecting the normal operation of the battery cell and the connector. In addition, the dustproof sealing ring adopts a double-layer sealing structure, including an outer sealing grid structure and an inner sealing ring structure. The outer sealing grid structure has a buffering and filtering function, which can block larger particles and dust, while the inner sealing ring structure provides a tighter sealing performance to prevent tiny particles and moisture from entering the interior of the connector. In a specific implementation, the dustproof sealing ring adopts fluororubber material and a double-layer sealing structure design, which can effectively prevent external environmental factors such as dust and water vapor from entering the interior of the connector, protect the battery cell and the connector from pollution and damage, and improve the reliability and stability of the connector. In addition, the effective dustproof and waterproof function of the dustproof sealing ring can extend the service life of the connector, reduce the damage and failure of the connector caused by external environmental factors such as dust and moisture, and reduce the maintenance and replacement costs. Secondly, by preventing the intrusion of external environmental factors, the dustproof sealing ring can keep the internal environment of the connector clean and dry, which is beneficial to the stability and performance of the battery cell and connector, and ensures the reliable operation of the connector in various working environments.

[0039] In the above embodiment, the magnetic positioning device 5 includes a magnetic positioning block 501, a magnetoresistor 502, a control circuit board 503 and a positioning indicator light 504; the magnetic positioning block 501 is located on the left side of the connector; the magnetoresistor 502 is installed inside the magnetic positioning device to detect changes in the magnetic field; a control circuit board 503 is arranged below the magnetoresistor 502 to receive and process signals emitted by the magnetic positioning block; the positioning indicator light 504 is located outside the magnetic positioning device and is connected to the control circuit board via a cable.

[0040] In a specific embodiment, when two matching connectors are close to each other, the magnetic positioning block 501 generates a magnetic field, which affects the magnetoresistor 502. The magnetoresistor 502 detects the change in the magnetic field and sends this information to the control circuit board 503. The control circuit board 503 determines whether the connectors are correctly aligned based on the signal sent by the magnetoresistor 502. If the connectors are correctly aligned, the control circuit board 503 sends a signal to control the positioning indicator light 504 to light up, indicating that the connectors have been successfully aligned.

[0041] In a specific embodiment, the magnetic positioning device 5 can automatically identify and position the two matching connectors, making the plugging and unplugging process simpler and more convenient. In addition, through the magnetic positioning device 5, the connectors can be accurately aligned, avoiding damage or unstable connection caused by inaccurate alignment. Secondly, the positioning indicator light 504 can provide a visual indication to let the user clearly know whether the connectors have been correctly aligned, thereby improving the convenience and reliability of user operation.

[0042] In the above embodiment, the adjustable locking device 4 is tightly combined with the connector body through bolts; the adjustable locking device 4 includes a locking knob 401, a threaded rod 402, a locking nut 403 and a locking seat groove 404; the locking knob 401 is located at the top of the connector; the locking knob 401 is connected to the threaded rod 402 through a groove; a locking nut 403 is arranged under the threaded rod 402, and the locking nut 403 is fixedly installed in the locking seat groove 404.

[0043] In a specific embodiment, the user controls the working state of the locking device by rotating the locking knob 401. When the locking knob 401 is rotated, the threaded rod 402 moves downward. The locking nut 403 is fixed to one end of the threaded rod and cooperates with the threaded rod 402 through a threaded structure to achieve the movement of the threaded rod. There is a locking seat groove 404 between the two parts of the connector. When the locking nut 404 is rotated and moved, it fixes or releases the locking seat groove, thereby controlling the locking state of the connector.

[0044] Specifically, when the user rotates the locking knob, the threaded rod 402 moves downward. The movement of the threaded rod 402 causes the locking nut 403 and the locking seat groove 404 to move accordingly, thereby fixing or releasing the locking seat groove. When the locking seat groove 404 is released, the two parts of the connector can move relative to each other, allowing the battery cell to be inserted or removed. When the locking seat groove 404 is fixed, the two parts of the connector are tightly locked together to ensure the stability and safety of the connection.

[0045] In a specific implementation, by rotating the locking knob 401, the user can flexibly adjust the working state of the locking device to adapt to the insertion or removal requirements of batteries of different sizes or shapes. Once the locking seat groove 404 is fixed, the two parts of the connector will be firmly locked together to ensure the stability and safety of the connection and prevent accidental falling off or loosening. By rotating the locking knob 402, the locking device is very easy to operate, and the user can easily lock or release the connector, which improves the convenience and efficiency of use.

[0046] In the above embodiment, the heat sink 6 is fixed to the top of the connector by means of thermally conductive adhesive.

[0047] In a specific embodiment, the heat sink 6 is fixed to the top of the connector by a thermally conductive adhesive. The thermally conductive adhesive is an adhesive with good thermal conductivity, which firmly bonds the heat sink 6 to the top of the connector to effectively transfer heat. When the connector is working, the internal circuits and components may generate heat. The heat sink 6 can effectively conduct the heat generated inside the connector to the surface of the heat sink by closely contacting the top of the connector. Once the heat is conducted to the surface of the heat sink, the heat sink can quickly dissipate the heat to the surrounding environment, and disperse the heat by natural convection or other heat dissipation methods to keep the temperature inside the connector within a safe range.

[0048] In a specific implementation, the presence of the heat sink 6 effectively disperses the heat generated inside the connector, preventing malfunctions and damages that may be caused by overheating. By effectively dissipating heat, the heat sink 6 can protect the electronic components in the connector from overheating, extend their service life and improve performance stability. In addition, the connector maintains a lower temperature during operation, which helps to improve the reliability and stability of the connector and reduce the risk of unexpected failures caused by excessive temperature.
