Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular discloses a waterproof and anti-detachment electric connector structure for new energy vehicles. Background Art

[0002] An electrical connector device generally includes a plug connector and a socket connector, which are used to mate with each other to achieve electrical connection. At present, it is difficult to set an anti-disconnection structure for a smaller cylindrical electrical connector device. When accidentally subjected to external force, they are easily disconnected from each other, resulting in accidental disconnection of the electrical connection of the electrical connector device. The safety performance needs to be improved. Therefore, there is an urgent need for a waterproof and anti-disconnection electrical connector structure for new energy vehicles. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a waterproof and anti-detachment electrical connector structure for new energy vehicles.

[0004] To achieve the above-mentioned purpose, the present invention provides a waterproof and anti-detachment electrical connector structure for new energy vehicles, including a first connector and a second connector; the first connector includes a first shell, on which a pin is provided, the second connector includes a second shell, on which a slot for accommodating the pin is provided, and the second shell is also provided with a first thread, and the first connector is sleeved with a locking assembly, the locking assembly includes a third shell, on which a second thread used to cooperate with the first thread is provided, and the locking assembly is used to be screwed with the second shell via the first thread and the second thread.

[0005] Preferably, the locking assembly includes a third shell, which is U-shaped and has a third groove body, which is sleeved on the second shell, and the first shell is provided with a first protrusion for use with the third shell, and the diameter of the first protrusion is larger than the diameter of the third groove body for limiting the third shell on one side. Through the U-shaped structure of the third shell and the cooperation between the third groove body and the first protrusion, a tight and stable connection between the locking assembly and the first connector and the second connector is achieved, thereby preventing the locking assembly from falling off the first connector, and effectively preventing the risk of the connector collapsing due to external forces such as vibration and impact. At the same time, the tight cooperation between the locking assembly and the first connector and the second connector helps the connector to be in close contact with the seal to form a tighter waterproof barrier, thereby improving the waterproof performance of the electrical system.

[0006] Preferably, the first protrusion is annular, and a ball is provided on one side of the first protrusion close to the third groove body, and the ball is used to reduce the friction between the third shell and the first protrusion and / or the first shell. The setting of the ball effectively reduces the friction resistance when the third shell slides on the first protrusion, thereby reducing the degree of wear, thereby extending the service life of the connector and reducing the risk of performance degradation or damage due to friction. The rolling action of the ball enables the third shell to rotate more smoothly along the first protrusion during installation or disassembly, thereby improving the smoothness and operability of the connection, helping to simplify the installation process and improve work efficiency.

[0007] Preferably, a second protrusion is also provided on the first shell, and a first groove body is formed between the second protrusion and the first protrusion. The first groove body is used to accommodate a seal, and the seal is used to form a sealed and waterproof structure between the second shell and the first shell. The seal significantly improves the waterproof performance of the connector and ensures the normal operation of the electrical system under severe weather conditions. In addition to the waterproof function, the seal can also increase the contact pressure and friction between the second shell and the first shell to a certain extent, thereby enhancing the stability of the connection and helping to prevent the connector from loosening or falling off due to vibration or impact during use. Although the addition of the seal increases the complexity of the connector, its installation and maintenance process is relatively simple. During installation, it is only necessary to place the seal correctly in the first groove body and ensure that the second shell is tightly fitted with the first shell. During maintenance, the seal can also be easily checked or replaced to ensure the continued waterproof performance of the connector.

[0008] Preferably, a reinforcement portion is provided on the second shell, and the diameter of the reinforcement portion is larger than the diameter of the second protrusion, and the diameter of the reinforcement portion is smaller than the diameter of the first protrusion so as to cooperate with the first protrusion to squeeze and stop the seal. The cooperation between the reinforcement portion and the first protrusion enables the seal to fit more tightly between the first shell and the second shell under the action of double extrusion, forming a solid waterproof barrier, significantly improving the sealing performance of the connector, and effectively preventing the invasion of moisture and dust. The provision of the reinforcement portion not only enhances the sealing effect, but also increases the connection strength between the second shell and the first shell to a certain extent, so that the connector can maintain the connection state more firmly when subjected to external force, avoiding loosening or falling off of the connection caused by vibration or impact. By precisely controlling the diameter of the reinforcement portion, it can not only form a close fit with the first protrusion, but also pass through the second protrusion smoothly, avoiding installation difficulties or damage caused by size mismatch. This design optimizes the overall structure of the connector and improves its reliability and durability.

[0009] Preferably, the reinforcement portion is cylindrical for accommodating the pin, the length of the reinforcement portion is not less than the length of the pin, and the Shore hardness of the reinforcement portion is not less than the Shore hardness of the second shell. The reinforcement portion is designed to be cylindrical and can tightly wrap the pin to provide additional protection and support for it, which helps prevent the pin from being damaged or deformed during connection or use, thereby ensuring the stability and reliability of the electrical connection. The length of the reinforcement portion is not less than the length of the pin, which helps prevent moisture or dust from penetrating into the interior of the connector through the gap between the pin and the shell, thereby ensuring the sealing performance of the connector. The Shore hardness of the reinforcement portion is not less than the Shore hardness of the second shell, which helps the reinforcement portion resist external impact and vibration and extend the service life of the connector. At the same time, the harder reinforcement portion can better maintain its shape and dimensional stability to ensure a close fit with the first shell.

[0010] Preferably, an anti-slip part made of a high friction coefficient is provided on the shell, and there are multiple anti-slip parts. The multiple anti-slip parts are arranged in a circular array around the shell, and the anti-slip parts protrude from the outer wall of the shell. The anti-slip parts are made of high friction coefficient material and can provide a stable anti-slip effect in various environments. When the user operates or holds the shell, the anti-slip part can increase the friction between the hand and the shell, effectively preventing the shell from slipping or rotating, thereby ensuring the stability and safety of the operation. The multiple anti-slip parts are arranged in a circular array around the shell, which not only enhances the anti-slip performance, but also improves the user's hand comfort. This design enables the user to hold the shell more firmly when holding it, reducing operational errors caused by hand fatigue or sliding. At the same time, the annular array distribution of the anti-slip parts also makes the appearance of the shell more beautiful and coordinated. The setting of the anti-slip parts not only has an anti-slip function, but also enhances the structural strength of the shell to a certain extent. They can disperse external impact force, reduce the risk of deformation and damage of the shell when it is collided or squeezed, and help to improve the overall durability and reliability of the connector.

[0011] Preferably, a second groove is further provided on the third shell, and the second groove is in a strip shape. A plurality of second grooves are arranged around the third shell array to increase the friction with the user's hand. The design of the strip-shaped second groove increases the concavity of the surface of the third shell. When the user's hand contacts the third shell, these grooves can provide more contact points, thereby significantly increasing the friction between the hand and the shell, allowing the user to hold or operate the third shell more steadily and reducing the risk of slipping or losing control. The plurality of second grooves are arranged around the third shell array, which not only increases the friction, but also allows the hand to fit more closely to the shell surface when holding, reduces the gap between the hand and the shell, and makes the user more comfortable when holding or operating for a long time, so that the third shell can maintain a stable grip in various environments.

[0012] Preferably, a protective part is provided on the side opposite to the first shell and the second shell, and the protective part is used to protect the cables arranged on the shell. By providing the protective part on the side opposite to the first shell and the second shell, an additional physical protection layer is effectively provided for the cables passing through or connected to the shell, which can reduce the risk of damage to the cables due to external environmental factors (such as friction, extrusion, pulling, etc.), thereby extending the service life of the cables and the entire device. The presence of the protective part not only protects the cables, but also indirectly improves the reliability of the entire device. The cables are important components for transmitting signals and power in the device, and their integrity is crucial to the normal operation of the device. The design of the protective part helps to ensure that the cables can maintain stable performance in harsh or complex working environments.

[0013] Preferably, a sixth groove is provided on the outer wall of the second protrusion, and a similar sixth groove is provided on the reinforcing portion and / or the first thread. The sixth groove is filled with the same identification material. The sixth groove and the identification material inside it can serve as a visual guide to help users or operators more accurately identify and operate the various components of the connector, especially in complex or emergency operating environments. This visual guide can reduce the possibility of misoperation and improve the accuracy and efficiency of operation.

[0014] Preferably, the electrical connector also includes a limit assembly, which includes a limit piece for use with the third shell and an annular piece fixedly arranged on the second shell, the limit piece is in the shape of a circular ring, and the first rod body portion and the second rod body portion are respectively arranged on both sides of the limit piece, and a fourth groove body for accommodating the first rod body portion is provided on the third shell, and the limit piece is slidably arranged relative to the third shell via the first rod body portion and the fourth groove body, and a fifth groove body for accommodating the second rod body portion is provided on the side of the annular piece close to the limit piece, and the fifth groove body is arranged along the annular array of the annular piece, and the second rod body portion cooperates with the fifth groove body on the annular piece to realize the limiting function of the limit piece and the third shell at a specific position, and since the fifth groove body is arranged along the annular array of the annular piece, the limit piece can be fixed at multiple different positions / angles, thereby meeting the limiting requirements of the electrical connector in different application scenarios and increasing the flexibility and applicability of the electrical connector.

[0015] Beneficial effects of the present invention: The connector structure achieves double fixation through the close fit of the pin and the slot, and the threaded connection (first thread and second thread) between the locking assembly and the second shell, effectively preventing the connector from falling off due to external forces such as vibration and impact during use. This stable connection method improves the connection stability of the electrical system and ensures the stable transmission of current and signals. Since the connector structure is stable and not easy to fall off, it can reduce the wear and damage to the connector caused by frequent plugging and unplugging, vibration and other factors, which helps to extend the service life of the connector, reduce replacement costs, and improve the overall reliability of new energy vehicles. The anti-dropping design of the connector structure can reduce the number of failures and repairs caused by the connector falling off. In addition, the structure also makes the installation and maintenance of the connector more convenient, further improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0027] See also Figures 1 to 8 As shown, a waterproof and anti-detachment electric connector structure for new energy vehicles of the present invention includes a first connector 1 and a second connector 2; the first connector 1 includes a first shell 11, and the first shell 11 is provided with a pin 16, the second connector 2 includes a second shell 21, and the second shell 21 is provided with a slot 25 for accommodating the pin 16, and the second shell 21 is also provided with a first thread 23, the first connector 1 is sleeved with a locking component 3, the locking component 3 includes a third shell 31, and the third shell 31 is provided with a second thread 34 used to cooperate with the first thread 23, and the locking component 3 is used to be screwed with the second shell 21 via the first thread 23 and the second thread 34.

[0028] Specifically, the connector structure achieves double fixation through the close fit between the pin 16 and the slot 25, and the threaded connection between the locking component 3 and the second shell 21 (the first thread 23 and the second thread 34), which effectively prevents the connector from falling off due to external forces such as vibration and impact during use. This stable connection method improves the connection stability of the electrical system and ensures the stable transmission of current and signals. Since the connector structure is stable and not easy to fall off (thanks to the close fit between the pin 16 and the slot 25 and the threaded tightening of the locking component 3), it can reduce the wear and damage to the connector caused by frequent plugging and unplugging, vibration and other factors, which helps to extend the service life of the connector, reduce replacement costs, and improve the overall reliability of new energy vehicles. The anti-drop design of the connector structure (including the close fit between the pin 16 and the slot 25 and the threaded tightening of the locking component 3) can reduce the number of failures and repairs caused by the connector falling off. In addition, the structure also makes the installation and maintenance of the connector more convenient, further improving the user experience.

[0029] Specifically, the locking assembly 3 includes a third shell 31, which is U-shaped and has a third groove 33. The third shell 31 is sleeved on the second shell 21. The first shell 11 is provided with a first protrusion 12 used in conjunction with the third shell 31. The diameter of the first protrusion 12 is larger than the diameter of the third groove 33 to limit the third shell 31 on one side. Through the U-shaped structure of the third shell 31 and the cooperation between the third groove 33 and the first protrusion 12, a tight and stable connection between the locking assembly 3 and the first connector 1 and the second connector 2 is achieved, thereby preventing the locking assembly 3 from falling off the first connector 1, and effectively preventing the risk of the connector collapsing due to external forces such as vibration and impact. At the same time, the tight cooperation between the locking assembly 3 and the first connector 1 and the second connector 2 helps the connector to be in close contact with the seal 15 to form a tighter waterproof barrier, thereby improving the waterproof performance of the electrical system.

[0030] Specifically, the first protrusion 12 is annular, and a ball is provided on one side of the first protrusion 12 close to the third groove body 33. The ball is used to reduce the friction between the third shell 31 and the first protrusion 12 and / or the first shell 11. The setting of the ball effectively reduces the friction resistance of the third shell 31 when sliding on the first protrusion 12, thereby reducing the degree of wear, thereby extending the service life of the connector and reducing the risk of performance degradation or damage due to friction. The rolling action of the ball enables the third shell 31 to rotate more smoothly along the first protrusion 12 during installation or disassembly, thereby improving the smoothness and operability of the connection, helping to simplify the installation process and improve work efficiency.

[0031] Specifically, a second protrusion 13 is further provided on the first shell 11, and a first groove 14 is formed between the second protrusion 13 and the first protrusion 12. The first groove 14 is used to accommodate a seal 15, and the seal 15 is used to form a sealed and waterproof structure with the second shell 21 and the first shell 11. The seal 15 significantly improves the waterproof performance of the connector and ensures the normal operation of the electrical system under severe weather conditions. In addition to the waterproof function, the seal 15 can also increase the contact pressure and friction between the second shell 21 and the first shell 11 to a certain extent, thereby enhancing the stability of the connection and helping to prevent the connector from loosening or falling off due to vibration or impact during use. Although the addition of the seal 15 increases the complexity of the connector, its installation and maintenance process is relatively simple. During installation, it is only necessary to correctly place the seal 15 in the first groove 14 and ensure that the second shell 21 is tightly fitted with the first shell 11. During maintenance, the seal 15 can also be easily checked or replaced to ensure the continued waterproof performance of the connector.

[0032] Specifically, in other embodiments, a waterproof label is provided on the second protrusion 13, and whether the waterproof label changes color helps the user determine the sealing performance of the seal 15. The color-changing function of the waterproof label provides the user with a simple and intuitive method to check the sealing performance of the seal. The user only needs to observe the color or state of the label to quickly determine whether the connector still has good waterproof capabilities. By timely detecting and discovering the decline in sealing performance, the user can take timely measures to maintain or replace the seal, thereby avoiding safety hazards such as short circuit and corrosion caused by moisture intrusion into the electrical system, which helps to improve the safety and reliability of the entire new energy vehicle electrical system.

[0033] Specifically, a reinforcing portion 26 is provided on the second shell 21, and the diameter of the reinforcing portion 26 is larger than the diameter of the second protrusion 13, and the diameter of the reinforcing portion 26 is smaller than the diameter of the first protrusion 12, so as to cooperate with the first protrusion 12 to squeeze and stop the sealing member 15. The cooperation between the reinforcing portion 26 and the first protrusion 12 enables the sealing member 15 to be more closely fitted between the first shell 11 and the second shell 21 under the action of double extrusion, forming a solid waterproof barrier, significantly improving the sealing performance of the connector, and effectively preventing the intrusion of moisture and dust. The reinforcing portion 26 The setting not only enhances the sealing effect, but also increases the connection strength between the second shell 21 and the first shell 11 to a certain extent, so that the connector can maintain the connection state more firmly when subjected to external force, avoiding loosening or falling off of the connection due to vibration or impact. By precisely controlling the diameter size of the reinforcement portion 26, it can form a tight fit with the first protrusion 12 and smoothly pass through the second protrusion 13, avoiding installation difficulties or damage caused by size mismatch. This design optimizes the overall structure of the connector and improves its reliability and durability.

[0034] Specifically, the reinforcing portion 26 is cylindrical for accommodating the pin 16, the length of the reinforcing portion 26 is not less than the length of the pin 16, the Shore hardness of the reinforcing portion 26 is not less than the Shore hardness of the second shell 21, and the reinforcing portion 26 is designed to be cylindrical and can tightly wrap the pin 16 to provide it with additional protection and support, which helps prevent the pin 16 from being damaged or deformed during connection or use, thereby ensuring the stability and reliability of the electrical connection. The length of the reinforcing portion 26 is not less than the length of the pin 16, which helps prevent moisture or dust from penetrating into the connector through the gap between the pin 16 and the shell, thereby ensuring the sealing performance of the connector. The Shore hardness of the reinforcing portion 26 is not less than the Shore hardness of the second shell 21, which helps the reinforcing portion 26 resist external impact and vibration and extend the service life of the connector. At the same time, the harder reinforcing portion 26 can better maintain its shape and dimensional stability to ensure a close fit with the first shell 11.

[0035] Specifically, an anti-slip member 22 made of a high friction coefficient is provided on the shell, and a plurality of anti-slip members 22 are provided. The plurality of anti-slip members 22 are arranged in an annular array around the shell, and the anti-slip members 22 protrude from the outer wall of the shell. The anti-slip members 22 are made of a material with a high friction coefficient and can provide a stable anti-slip effect in various environments. When the user is operating or holding the shell, the anti-slip member 22 can increase the friction between the hand and the shell, effectively preventing the shell from slipping or rotating, thereby ensuring the stability and safety of the operation. The plurality of anti-slip members 22 are arranged in an annular array around the shell, which not only enhances the anti-slip performance, but also improves the user's hand comfort. This design enables the user to hold the shell more firmly when holding it, reducing operational errors caused by hand fatigue or sliding. At the same time, the annular array distribution of the anti-slip members 22 also makes the appearance of the shell more beautiful and coordinated. The setting of the anti-slip members 22 not only has an anti-slip function, but also enhances the structural strength of the shell to a certain extent. They can disperse external impact forces, reduce the risk of deformation and damage of the shell when it is collided or squeezed, and help improve the overall durability and reliability of the connector.

[0036] Specifically, a second groove 32 is further provided on the third shell 31. The second groove 32 is in a strip shape. Multiple second grooves 32 are arranged in an array around the third shell 31 to increase the friction with the user's hand. The design of the strip-shaped second groove 32 increases the concavity of the surface of the third shell 31. When the user's hand contacts the third shell 31, these grooves can provide more contact points, thereby significantly increasing the friction between the hand and the shell, allowing the user to hold or operate the third shell 31 more steadily and reducing the risk of slipping or losing control. Multiple second grooves 32 are arranged in an array around the third shell 31, which not only increases the friction, but also allows the hand to fit more closely to the shell surface when holding, reducing the gap between the hand and the shell, making the user more comfortable when holding or operating for a long time, so that the third shell 31 can maintain a stable grip in various environments.

[0037] Specifically, a protective part 24 is provided on the side opposite to each other from the first shell 11 and the second shell 21. The protective part 24 is used to protect the cables arranged on the shells. By providing the protective part 24 on the side opposite to each other from the first shell 11 and the second shell 21, an additional physical protection layer is effectively provided for the cables passing through or connected to the shells, which can reduce the risk of damage to the cables due to external environmental factors (such as friction, extrusion, pulling, etc.), thereby extending the service life of the cables and the entire device. The existence of the protective part 24 not only protects the cables, but also indirectly improves the reliability of the entire device. The cables are important components for transmitting signals and power in the device. Their integrity is crucial to the normal operation of the device. The design of the protective part 24 helps to ensure that the cables can still maintain stable performance in harsh or complex working environments.

[0038] Specifically, a sixth groove 17 is provided on the outer wall of the second protrusion 13, and a similar sixth groove 17 is provided on the reinforcement portion 26 and / or the first thread 23. The sixth groove 17 is filled with the same identification material. The sixth groove 17 and the identification material therein can serve as a visual guide to help users or operators more accurately identify and operate the various components of the connector, especially in complex or emergency operating environments. Such visual guidance can reduce the possibility of misoperation and improve the accuracy and efficiency of operation.

[0039] Specifically, the sixth slot 17 may be filled with fluorescent material.

[0040] Specifically, a shock-absorbing material layer made of an elastic material (such as rubber, silicone or polyurethane, etc.) is provided between the mating surfaces of the first connector 1 and the second connector 2, such as the end of the pin 16. The shock-absorbing material layer can effectively absorb the impact force and vibration generated during the plugging or locking process, protect the pin 16 from damage, and improve the durability and stability of the connector. In this embodiment, the pin 16 is a first terminal portion, and a second terminal portion is provided on the second shell 21. Figure 3 .

[0041] Specifically, the electrical connector also includes a limit assembly 4, which includes a limit member 41 for use with the third housing 31 and a ring member 46 fixedly arranged on the second housing 21. The limit member 41 is annular, and the first rod body portion 42 and the second rod body portion 43 are respectively arranged on both sides of the limit member 41. The third housing 31 is provided with a fourth groove 35 for accommodating the first rod body portion 42. The limit member 41 is slidably arranged relative to the third housing 31 via the first rod body portion 42 and the fourth groove 35. The ring member 46 is close to the limit member 41. A fifth groove 47 for accommodating the second rod body portion 43 is provided on one side, and the fifth groove 47 is arranged along the annular array of the ring member 46. The second rod body portion 43 cooperates with the fifth groove 47 on the annular member 46 to realize the limiting function of the limiting member 41 and the third shell 31 at a specific position. Since the fifth groove 47 is arranged along the annular array of the ring member 46, the limiting member 41 can be fixed at multiple different positions / angles, thereby meeting the limiting requirements of the electrical connector in different application scenarios and increasing the flexibility and applicability of the electrical connector.

[0042] Specifically, an elastic member 44 is further provided on a side of the limiting member 41 close to the third shell 31 , and the limiting member 41 is connected to the third shell 31 via the elastic member 44 .

[0043] Specifically, the elastic member 44 is made of a material that does not generate electromagnetic interference, such as stainless steel (304, 316), rubber material, etc.

[0044] Specifically, at least two first rod parts 42 and at least two second rod parts 43 are provided.

[0045] Specifically, in other embodiments, a magnetic isolation layer is injection-molded inside the third shell 31 .

[0046] Specifically, in other embodiments, the end of the limiting member 41 is bent and extended with a side wall to form a U-shaped structure that is sleeved on the third shell 31, which is stable and more beautiful.

[0047] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
