Description

Technical Field

[0001] The present invention relates to a sealing ring and an electrical connector including the same. Background Art

[0002] The battery installation methods of existing electric vehicles are generally divided into fixed type and replaceable type. Among them, the fixed batteries are generally fixed on the vehicle, and the vehicle is directly used as the charging object during charging. The replaceable batteries generally adopt a movable installation method, and the battery can be removed at any time for replacement or charging. After replacement or charging is completed, it is reinstalled on the vehicle body.

[0003] For existing replaceable-structured batteries, corresponding installation positions are generally provided on the body bracket of the vehicle body. After the battery is placed in the installation position, it is connected to the vehicle-end electrical connector on the vehicle body through the battery-end electrical connector, and then fixed by a locking device.

[0004] A sealing ring is provided on the docking electrical connection side between the vehicle-end electrical connector and the battery-end electrical connector to achieve sealing, so as to ensure that the contact between the high-voltage and low-voltage pole columns of the battery-end electrical connector on the battery and the high-voltage and low-voltage pole columns of the vehicle-end electrical connector is continuous and stable, and the electrical connector is well sealed, so as to prevent the power supply of the electric vehicle from being affected by wading or other external environments, and ensure stable power output during driving.

[0005] Currently, the sealing force of the sealing ring on the electrical connector is relatively large, and the material of the sealing ring is rubber. After the rubber material undergoes permanent deformation, there is a risk of sealing failure and the fixed bracket may deform after being stressed for a long time, resulting in a risk of sealing failure of the electrical connector. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the sealing force of the sealing ring on the electrical connector is relatively large, the material of the sealing ring is rubber, there is a risk of sealing failure after the rubber material undergoes permanent deformation, and the fixed bracket deforms after being stressed for a long time, resulting in a risk of sealing failure of the electrical connector, and to provide a sealing ring and an electrical connector including the same.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A sealing ring, the sealing ring includes an installation component and a abutting component. The installation component is used for installation and connection on a first electrical connector, the first electrical connector is used for cooperating with a second electrical connector to achieve electrical connection, one side of the abutting component is connected to the installation component, and the other side of the abutting component is used for abutting against the second electrical connector. When the first electrical connector and the second electrical connector are electrically connected, a sealed hollow cavity is formed between the abutting component and the installation component.

[0009] In this solution, with the above structural form, the sealing ring abuts against the second electrical connector through the abutting member. A sealed hollow cavity is formed between the abutting member and the mounting member. Through the sealed hollow cavity, a supporting force will be generated during the process of the sealing ring deforming under force, and a sealing thrust is always formed on the first electrical connector and the second electrical connector. Moreover, during the use of the electrical connector, even if the electrical connector vibrates, the reaction force of the sealing ring can be increased through the sealed hollow cavity, so that the sealing ring can always act on the second electrical connector, improving the sealing effect of the electrical connector. At the same time, through the sealed hollow cavity, the deformation compression space of the sealing ring can be increased, the compression ratio of the sealing ring can be increased, and the permanent deformation coefficient of the sealing ring can be improved, thereby improving the durability of the sealing ring itself; during the process of the sealing ring deforming under force, it always acts on the first electrical connector and the second electrical connector. During the compression process, the compression amount of the material of the sealing ring can be reduced through the sealed hollow cavity, thereby effectively reducing the compression force exerted by the second electrical connector on the sealing ring, reducing the thrust of the second electrical connector on the sealing ring and the first electrical connector, thereby reducing the rigid requirement for installing the electrical connector and extending the service life of the sealing ring.

[0010] Preferably, the abutting member includes a connecting portion, an abutting portion, and an elastic sealing portion connected in sequence. The connecting portion is connected to the mounting member. A hollow structure is formed between the abutting portion and the mounting member. The abutting portion abuts against the second electrical connector to drive the elastic sealing portion to be able to move in a direction close to or away from the mounting member and has an initial state and a sealing state.

[0011] In the initial state, an opening communicating with the hollow structure is formed between the elastic sealing portion and the mounting member.

[0012] In the sealing state, the elastic sealing portion seals and abuts against the mounting member so that the sealed hollow cavity is formed between the abutting member and the mounting member.

[0013] In this solution, with the above structural form, the inside of the abutting member has a hollow structure and has an opening at one end. Through the opening, a hollow structure can be processed and made inside the sealing ring, realizing the feasibility of production, thereby reducing the production cost; and when the first electrical connector and the second electrical connector are disconnected from each other, it will automatically return to the initial state, effectively preventing the sealing ring from being damaged by vacuum extraction when opened, improving the service life of the sealing ring, and improving the sealing reliability of the electrical connector.

[0014] Preferably, in the initial state, the gap between the elastic sealing portion and the mounting member is smaller than the dimension of the hollow structure along the axial direction of the sealing ring.

[0015] In this solution, adopting the above structural form, since the gap between the elastic sealing part and the mounting part is smaller than the dimension of the hollow structure along the axial direction of the sealing ring, during the movement, the elastic sealing part will first abut against the mounting part while the inner wall surface of the abutting part does not abut against the mounting part. The elastic sealing part will close the opening to form a sealed hollow cavity. The sealing ring always forms a sealing thrust on the first electrical connector and the second electrical connector through the sealed hollow cavity, thereby effectively enhancing the sealing effect of the sealing ring; through the sealed hollow cavity, the deformation compression space of the sealing ring can be increased, the compression ratio of the sealing ring can be increased, and the permanent deformation coefficient of the sealing ring can be improved, thereby enhancing the durability of the sealing ring itself; meanwhile, during the compression process, the compression amount of the material of the sealing ring can be reduced through the sealed hollow cavity, effectively reducing the compression force exerted by the second electrical connector on the sealing ring, so that the thrust of the second electrical connector on the sealing ring and the first electrical connector will be reduced, thereby reducing the rigid requirement for installing the electrical connector and prolonging the service life of the sealing ring.

[0016] Preferably, the abutting component further includes a first convex portion. One end of the first convex portion is connected to the side of the abutting part facing away from the mounting part, and the other end of the first convex portion extends and protrudes axially outward along the sealing ring and is used for abutting against the second electrical connector.

[0017] In this solution, adopting the above structural form, the abutting component abuts and seals with the second electrical connector through the first convex portion, thereby further enhancing the sealing effect between the abutting component and the second electrical connector.

[0018] Preferably, the end face of the first convex portion facing the second electrical connector is a spherical surface.

[0019] In this solution, adopting the above structural form, the first convex portion will seal and abut against the second electrical connector through the spherical surface. The spherical surface uses an arc structure for contact and abutment, thereby further enhancing the sealing effect between the abutting component and the second electrical connector.

[0020] Preferably, the number of the first convex portions is multiple, and the multiple first convex portions are arranged at intervals so that a concave groove is formed between any two adjacent first convex portions.

[0021] In this solution, adopting the above structural form, multiple first convex portions will simultaneously abut against the second electrical connector, and multiple seals will be formed by the multiple first convex portions, further improving the sealing performance of the electrical connector. At the same time, a recessed groove is formed between any two adjacent first convex portions. When the second electrical connector abuts against two adjacent first convex portions, a sealed cavity is formed between the two adjacent first convex portions through the recessed groove. The sealed cavity realizes the function of sealing compression compensation in dynamic compression contact, further improving the sealing effect of the electrical connector, enhancing the durability of the sealing ring itself, extending the service life of the sealing ring, and reducing the rigid requirement for the installation of the electrical connector.

[0022] Preferably, the elastic sealing portion is located inside the connecting portion. The multiple first convex portions are arranged at intervals along the radial direction of the sealing ring, and the distance between the multiple first convex portions and the second electrical connector gradually decreases from outside to inside along the radial direction of the sealing ring.

[0023] In this solution, adopting the above structural form, during the approaching process of the first electrical connector and the second electrical connector, the first convex portions from the innermost to the outermost layer abut against the second electrical connector layer by layer, achieving a multi-level sealing effect between the sealing ring and the second electrical connector, effectively preventing air from being mixed in the middle and affecting the sealing effect. At the same time, the innermost first convex portion will first cause the elastic sealing portion to close the opening to form a sealed hollow cavity. Through the sealed hollow cavity, the sealing ring always forms a sealing thrust on the first electrical connector and the second electrical connector, improving the sealing effect of the electrical connector; and effectively reducing the compression force exerted by the second electrical connector on the sealing ring, thereby reducing the rigid requirement for installing the electrical connector and extending the service life of the sealing ring. At the same time, the sealing ring improves the permanent deformation coefficient of the sealing ring through the sealed hollow cavity, thereby enhancing the durability of the sealing ring itself.

[0024] Preferably, in the initial state, the axial distance between the outermost first convex portion and the innermost first convex portion along the sealing ring is not less than the opening gap between the elastic sealing portion and the mounting component.

[0025] In this solution, adopting the above structural form, during the process of the abutting part and the second electrical connector abutting against each other, the innermost first convex part comes into contact with the second electrical connector first. Then, the elastic sealing part and the mounting part abut against each other, and the opening closes. Finally, the outermost first convex part abuts against the second electrical connector, keeping the abutting part and the second electrical connector in a squeezed state all the time, improving the sealing effect between the first electrical connector and the second electrical connector. At the same time, through the setting of the above gap size, during the process of the abutting part and the second electrical connector separating from each other, the outermost first convex part separates from the second electrical connector first. Then, the elastic sealing part and the mounting part separate. Finally, the innermost first convex part separates from the second electrical connector, making it easier for the first electrical connector and the second electrical connector to separate.

[0026] Preferably, one end of the elastic sealing part is connected to the abutting part, and the other end of the elastic sealing part extends in the direction close to the mounting part, so that the side of the abutting part facing the mounting part has a groove recessed outward.

[0027] In this solution, adopting the above structural form, when the elastic sealing part and the mounting part abut against each other, the abutting part and the mounting part have not come into contact and abutted yet, ensuring that a sealed hollow cavity is formed when the sealing ring is in an internal sealed state, realizing that the sealing ring always acts on the second electrical connector, improving the sealing effect of the electrical connector; and increasing the permanent deformation coefficient of the sealing ring, thereby improving the durability of the sealing ring itself; effectively reducing the compression force exerted by the second electrical connector on the sealing ring, thus reducing the rigid requirement for installing the electrical connector and prolonging the service life of the sealing ring. At the same time, the overall structure is simple, convenient for processing and manufacturing, and reduces the production cost.

[0028] Preferably, the abutting part further includes a second convex part. The second convex part is connected to the outer side in the radial direction of the abutting part and extends outward in a convex shape, and / or the second convex part is connected to the inner side in the radial direction of the abutting part and extends inward in a convex shape. The second convex part abuts against the second electrical connector.

[0029] In this solution, adopting the above structural form, the second convex part and the first convex part are located on different sides of the abutting part. The abutting part extends and protrudes radially through the second convex part and abuts against the second electrical connector, enabling a radial sealing effect between the sealing ring and the second electrical connector, increasing the sealing ability of the sealing ring, and further improving the sealing performance of the electrical connector.

[0030] Preferably, the mounting component includes a fixing part, a sleeve part, and a floating part. The abutting component is connected to the floating part. The fixing part and the floating part are respectively connected to two ends of the sleeve part, and an annular groove for sleeving and connecting to the first electrical connector is formed among the fixing part, the sleeve part, and the floating part.

[0031] In this solution, adopting the above structural form enables the abutting component to abut against the second electrical connector and achieve floating connection. During use, even if there is a certain deviation in the second electrical connector, stable sealing with the abutting component can still be achieved, thereby improving the sealing effect of the electrical connector. The first electrical connector is wrapped inside by the annular groove, and the waterproof sealing effect is better.

[0032] Preferably, the connecting part, the abutting part, and the elastic sealing part are of a continuous arc structure.

[0033] In this solution, adopting the above structural form, since the abutting component has a continuous arc structure for the connecting part, the abutting part, and the elastic sealing part, the internal space of the sealed hollow cavity formed when the elastic sealing part abuts against the mounting component is relatively large, resulting in a large compression stroke of the sealing ring. Thus, the compression force exerted by the second electrical connector on the sealing ring is further reduced, the thrust of the second electrical connector on the sealing ring and the first electrical connector is decreased, the rigid requirement for installing and setting this electrical connector is lowered, and the service life of the sealing ring is extended. At the same time, during the compression process, the pressure received by the sealing ring is balanced and the stability is higher.

[0034] Preferably, the mounting component includes a fixing part, a sleeve part, a floating part, and a limiting part. The fixing part and the floating part are respectively connected to two ends of the sleeve part, and an annular groove for sleeving and connecting to the first electrical connector is formed among the fixing part, the sleeve part, and the floating part. The connecting part and the limiting part are respectively connected to the upper end and the lower end on the same side of the floating part, and the elastic sealing part is located between the connecting part and the limiting part;

[0035] When the elastic sealing part abuts against the floating part, the limiting part restricts the elastic sealing part from moving outward along the direction away from the connecting part on the surface of the floating part.

[0036] In this solution, adopting the above structural form, by the limiting part blocking and restricting the elastic sealing part from moving along the direction away from the connecting part on the surface of the floating part, the floating part always closely abuts against the surface of the floating part, effectively avoiding affecting the sealing effect and having higher stability.

[0037] An electrical connector includes a sealing ring as described above.

[0038] In this solution, with the above structural form, when the sealing ring deforms under force through the sealed hollow cavity, a supporting force will be generated, and a sealing thrust will always be formed on the first electrical connector and the second electrical connector. Moreover, during the use of the electrical connector, even if the electrical connector vibrates, the reaction force of the sealing ring can be increased through the sealed hollow cavity, enabling the sealing ring to always act on the second electrical connector, thereby improving the sealing effect of the electrical connector. At the same time, the sealed hollow cavity can increase the deformation compression space of the sealing ring, increase the compression ratio of the sealing ring, and improve the permanent deformation coefficient of the sealing ring, thus enhancing the durability of the sealing ring itself. During the process of the sealing ring deforming under force, it always acts on the first electrical connector and the second electrical connector. During compression, the sealed hollow cavity can reduce the compression amount of the material of the sealing ring, thereby effectively reducing the compression force exerted by the second electrical connector on the sealing ring, reducing the thrust of the second electrical connector on the sealing ring and the first electrical connector, thereby reducing the rigid requirement for installing the electrical connector and extending the service life of the sealing ring.

[0039] Preferably, a circular groove is formed on one side of the second electrical connector facing the first electrical connector, and the abutting member is embedded in the circular groove.

[0040] In this solution, with the above structural form, when the first electrical connector and the second electrical connector are electrically connected, the abutting member will be embedded in the circular groove, thereby further improving the sealing effect of the electrical connector and having higher safety. At the same time, the circular groove will restrict the abutting member, effectively preventing the phenomenon of offset and dislocation of the abutting member during the use of the sealing ring, and further improving the stability of the electrical connector.

[0041] On the basis of conforming to the common knowledge in the art, the above preferred conditions can be combined arbitrarily to obtain various preferred examples of the present invention.

[0042] The positive and progressive effects of the present invention are as follows:

[0043] The sealing ring of the present invention and the electrical connector including the same. When the first electrical connector and the second electrical connector are electrically connected, the sealing ring abuts against the second electrical connector through an abutting member and forms a sealed hollow cavity, so that the sealing ring always forms a sealing thrust on the first electrical connector and the second electrical connector. Moreover, during the use of the electrical connector, even if the electrical connector vibrates, the reaction force of the sealing ring can be increased through the sealed hollow cavity, so that the sealing ring can always act on the second electrical connector, improving the sealing effect of the electrical connector. At the same time, through the sealed hollow cavity, the deformation compression space of the sealing ring can be increased, the compression ratio of the sealing ring can be increased, the permanent deformation coefficient of the sealing ring can be improved, thereby improving the durability of the sealing ring itself. At the same time, during the compression process, the compression amount of the material of the sealing ring can be reduced through the sealed hollow cavity, thereby effectively reducing the compression force exerted by the second electrical connector on the sealing ring, so that the thrust of the second electrical connector on the sealing ring and the first electrical connector will be reduced, thereby reducing the rigidity requirement for installing and setting the electrical connector, and extending the service life of the sealing ring.

[0072] The present invention will be more clearly and completely described below by way of examples in conjunction with the drawings, but the present invention is not limited to the scope of the examples accordingly.

[0073] Example 1

[0074] As Figures 1 to 6 shown, the embodiment of the present invention discloses an electrical connector, which can be installed on an electric vehicle, a battery pack, a charging rack, etc. The electrical connector includes a sealing ring 10, a first electrical connector 20 and a second electrical connector 30. The sealing ring 10 includes a mounting member 1 and an abutting member 2. The mounting member 1 is used for mounting and connecting to the first electrical connector 20. The first electrical connector 20 is used for cooperating with the second electrical connector 30 to achieve electrical connection. One side of the abutting member 2 is connected to the mounting member 1, and the other side of the abutting member 2 is used for abutting against the second electrical connector 30. When the first electrical connector 20 and the second electrical connector 30 are electrically connected, a sealed hollow cavity 3 is formed between the abutting member 2 and the mounting member 1.

[0075] The sealing ring 10 is installed and connected to the first electrical connector 20 through the installation component 1. When the first electrical connector 20 is electrically connected to the second electrical connector 30, the sealing ring 10 abuts against the second electrical connector 30 through the abutting component 2. At the same time, a sealed hollow cavity 3 is formed between the abutting component 2 and the installation component 1. Through the sealed hollow cavity 3, a supporting force will be generated when the sealing ring 10 is deformed under force, and a sealing thrust is always formed on the first electrical connector 20 and the second electrical connector 30. Moreover, during the use of the electrical connector, even if the electrical connector vibrates, the reaction force of the sealing ring 10 can be increased through the sealed hollow cavity 3, so that the sealing ring 10 can always act on the second electrical connector 30, improving the sealing effect of the electrical connector.

[0076] In addition, through the sealed hollow cavity 3, the deformation compression space of the sealing ring 10 can be increased, the compression ratio of the sealing ring 10 can be increased, and the permanent deformation coefficient of the sealing ring 10 can be improved, thereby improving the durability of the sealing ring 10 itself. At the same time, during the process of the sealing ring 10 being deformed under force, it always acts on the first electrical connector 20 and the second electrical connector 30. During the compression process, the compression amount of the material of the sealing ring 10 can be reduced through the sealed hollow cavity 3, thereby effectively reducing the compression force exerted by the second electrical connector 30 on the sealing ring 10, so that the thrust of the second electrical connector 30 on the sealing ring 10 and the first electrical connector 20 will be reduced, thereby reducing the rigid requirement for installing and setting the electrical connector, and extending the service life of the sealing ring 10. Among them, the installation component 1 and the abutting component 2 are integrally formed, which is convenient for processing and manufacturing and has high structural stability.

[0077] As Figure 2 and Figure 3 shown, a circular groove 301 is formed on one side of the second electrical connector 30 facing the first electrical connector 20, and the abutting component 2 is embedded in the circular groove 301. When the first electrical connector 20 and the second electrical connector 30 are electrically connected, the abutting component 2 will be embedded in the circular groove 301, thereby further improving the sealing effect of the electrical connector and having higher safety. At the same time, the circular groove 301 will play a limiting role on the abutting component 2, effectively avoiding the phenomenon of offset and dislocation of the abutting component 2 during the use of the sealing ring 10, and further improving the stability of the electrical connector.

[0078] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, the abutting member 2 includes a connecting portion 21, an abutting portion 22, and an elastic sealing portion 23 that are connected in sequence. The connecting portion 21 is connected to the mounting member 1. A hollow structure 24 is formed between the abutting portion 22 and the mounting member 1. The abutting portion 22 abuts against the second electrical connector 30 to drive the elastic sealing portion 23 to be able to move in a direction close to or away from the mounting member 1 and has an initial state and a sealing state. In the initial state, an opening 25 communicating with the hollow structure 24 is formed between the elastic sealing portion 23 and the mounting member 1. In the sealing state, the elastic sealing portion 23 seals and abuts against the mounting member 1 so that a sealed hollow cavity 3 is formed between the abutting member 2 and the mounting member 1.

[0079] When the second electrical connector 30 and the first electrical connector 20 are disconnected from each other, the elastic sealing portion 23 can move in a direction away from the mounting member 1, so that the sealing ring 10 is in the initial state. A gap is formed between the elastic sealing portion 23 and the mounting member 1 and an opening 25 is formed. The hollow structure 24 communicates with the outside through the opening 25. When the second electrical connector 30 and the first electrical connector 20 are connected to each other, the sealing ring 10 is in the sealing state. The abutting portion 22 abuts against the second electrical connector 30 and drives the elastic sealing portion 23 to move in a direction close to the mounting member 1, so that the elastic sealing portion 23 seals and abuts against the mounting member 1, so that a sealed hollow cavity 3 is formed between the abutting member 2 and the mounting member 1.

[0080] During use, the electrical connector is connected or disconnected between the first electrical connector 20 and the second electrical connector 30 to effect the switching between the sealing state and the initial state. The interior of the abutting member 2 has a hollow structure 24 and has an opening 25 at one end. Through the opening 25, the hollow structure 24 can be machined inside the sealing ring 10, realizing the feasibility of production, thereby reducing the production cost. And when the first electrical connector 20 and the second electrical connector 30 are disconnected from each other, it will automatically return to the initial state, effectively preventing the sealing ring 10 from being damaged by vacuum extraction when opened, improving the service life of the sealing ring 10, and improving the sealing reliability of the electrical connector.

[0081] Among them, in the initial state, the gap between the elastic sealing part 23 and the mounting part 1 is smaller than the dimension of the hollow structure 24 along the axial direction of the sealing ring 10. During the connection process of the second electrical connector 30 and the first electrical connector 20, the second electrical connector 30 will apply a abutting force on the abutting part 2, causing both the abutting part 22 and the elastic sealing part 23 to move in the direction close to the mounting part 1. Since the gap between the elastic sealing part 23 and the mounting part 1 is smaller than the dimension of the hollow structure 24 along the axial direction of the sealing ring 10, during the movement, the elastic sealing part 23 will first abut against the mounting part 1 while the inner wall surface of the abutting part 22 does not abut against the mounting part 1. The elastic sealing part 23 will close the opening 25 so that the hollow structure 24 forms a sealed cavity, that is, a sealed hollow cavity 3 is formed. The sealing ring 10 always forms a sealing thrust on the first electrical connector 20 and the second electrical connector 30 through the sealed hollow cavity 3, thereby effectively enhancing the sealing effect of the sealing ring 10; through the sealed hollow cavity 3, the deformation compression space of the sealing ring 10 can be increased, the compression ratio of the sealing ring 10 can be increased, and the permanent deformation coefficient of the sealing ring 10 can be improved, thereby improving the durability of the sealing ring 10 itself; at the same time, during the compression process, through the sealed hollow cavity 3, the compression amount of the material of the sealing ring 10 can be reduced, the compression force applied by the second electrical connector 30 on the sealing ring 10 can be effectively reduced, so that the thrust of the second electrical connector 30 on the sealing ring 10 and the first electrical connector 20 will be reduced, thereby reducing the rigid requirement for installing the electrical connector and extending the service life of the sealing ring 10.

[0082] The abutting part 2 further includes a first protrusion 26. One end of the first protrusion 26 is connected to the side of the abutting part 22 facing away from the mounting part 1, and the other end of the first protrusion 26 extends and protrudes axially outward along the sealing ring 10 and is used to abut against the second electrical connector 30. The first protrusion 26 is arranged on the abutting part 22 and extends and protrudes axially outward along the sealing ring 10, so that the abutting part 2 abuts and seals with the second electrical connector 30 through the first protrusion 26, thereby further enhancing the sealing effect between the abutting part 2 and the second electrical connector 30.

[0083] The end face of the first protrusion 26 facing the second electrical connector 30 is a spherical surface 261. When the first electrical connector 20 and the second electrical connector 30 are electrically connected, the first protrusion 26 will seal and abut against the second electrical connector 30 through the spherical surface 261. The spherical surface 261 uses an arc structure for contact and abutment, thereby further enhancing the sealing effect between the abutting part 2 and the second electrical connector 30.

[0084] The number of the first protrusions 26 is multiple, and the multiple first protrusions 26 are arranged at intervals so that a recessed groove 262 is formed between any two adjacent first protrusions 26. The multiple first protrusions 26 will simultaneously abut against the second electrical connector 30, and multiple seals will be formed by the multiple first protrusions 26, further improving the sealing performance of the electrical connector. At the same time, a recessed groove 262 is formed between any two adjacent first protrusions 26. When the second electrical connector 30 abuts against two adjacent first protrusions 26, a sealing cavity is formed between the two adjacent first protrusions 26 through the recessed groove 262. The sealing cavity realizes the function of sealing compression supplement in dynamic compression contact, further improving the sealing effect of the electrical connector, enhancing the durability of the sealing ring 10 itself, extending the service life of the sealing ring 10, and reducing the rigid requirement for the installation of the electrical connector.

[0085] The elastic sealing portion 23 is located inside the connecting portion 21. A plurality of first convex portions 26 are arranged at intervals along the radial direction of the sealing ring 10, and the distance between the plurality of first convex portions 26 and the second electrical connector 30 gradually decreases from outside to inside along the radial direction of the sealing ring 10. By arranging the elastic sealing portion 23 inside the connecting portion 21, the opening 25 faces inward, thereby effectively preventing external impurities from entering the hollow structure 24 through the opening 25, ensuring the normal use of the sealing ring 10 and making it more stable and reliable. At the same time, the distance between the plurality of first convex portions 26 and the second electrical connector 30 gradually decreases from outside to inside along the radial direction of the sealing ring 10. The plurality of first convex portions 26 are in stepped contact, that is, the innermost first convex portion 26 first contacts and abuts against the second electrical connector 30, that is, the first convex portion 26 closest to the axis line of the sealing ring 10 first contacts and abuts against the second electrical connector 30, and the outermost first convex portion 26 last contacts and abuts against the second electrical connector 30, that is, the first convex portion 26 farthest from the axis line of the sealing ring 10 last contacts and abuts against the second electrical connector 30; during the process of the innermost first convex portion 26 contacting and abutting against the second electrical connector 30, it will drive the elastic sealing portion 23 to move in the direction close to the mounting member 1 and first abut against the mounting member 1. During the approach of the first electrical connector 20 and the second electrical connector 30, from the innermost first convex portion 26 to the outermost first convex portion 26, they are successively in contact with the second electrical connector 30, achieving a multi-level sealing effect between the sealing ring 10 and the second electrical connector 30, effectively preventing air from being mixed in the middle and affecting the sealing effect. At the same time, the innermost first convex portion 26 will first cause the elastic sealing portion 23 to close the opening 25 to form a sealed hollow cavity 3. Through the sealed hollow cavity 3, the sealing ring 10 always forms a sealing thrust on the first electrical connector 20 and the second electrical connector 30, improving the sealing effect of the electrical connector; and effectively reducing the compression force applied by the second electrical connector 30 on the sealing ring 10, thereby reducing the rigid requirement for installing the electrical connector and prolonging the service life of the sealing ring 10. At the same time, the sealing ring 10 improves the permanent deformation coefficient of the sealing ring 10 through the sealed hollow cavity 3, thereby improving the durability of the sealing ring 10 itself.

[0086] Among them, in the initial state, the axial distance between the outermost first convex portion 26 and the innermost first convex portion 26 along the sealing ring 10 is not less than the opening 25 gap between the elastic sealing portion 23 and the mounting member 1. During the connection process between the second electrical connector 30 and the first electrical connector 20, the second electrical connector 30 will first come into contact with and abut against the innermost first convex portion 26, and drive the elastic sealing portion 23 to move in the direction close to the mounting member 1. Since the axial distance between the outermost first convex portion 26 and the innermost first convex portion 26 along the sealing ring 10 is not less than the opening 25 gap between the elastic sealing portion 23 and the mounting member 1, that is, during the mutual abutment of the abutting portion 22 and the second electrical connector 30, the innermost first convex portion 26 first comes into contact with the second electrical connector 30, and then the elastic sealing portion 23 and the mounting member 1 abut against each other, the opening 25 closes, and finally the outermost first convex portion 26 abuts against the second electrical connector 30, so that the abutting portion 22 and the second electrical connector 30 are always in a compressed state, improving the sealing effect between the first electrical connector 20 and the second electrical connector 30. At the same time, through the setting of the above gap size, during the mutual separation of the abutting portion 22 and the second electrical connector 30, the outermost first convex portion 26 first separates from the second electrical connector 30, then the elastic sealing portion 23 and the mounting member 1 separate, and finally the innermost first convex portion 26 separates from the second electrical connector 30, making it easier for the first electrical connector 20 and the second electrical connector 30 to separate. When the elastic sealing portion 23 and the mounting member 1 abut against each other, the second electrical connector 30 does not apply a force on the outermost first convex portion 26. After the elastic sealing portion 23 closes the opening 25 to form the sealed hollow cavity 3, the second electrical connector 30 then applies a force on the outermost first convex portion 26, so that a sealed hollow cavity 3 has been formed in the sealing ring 10 and always acts on the second electrical connector 30, improving the sealing effect of the electrical connector; and increasing the permanent deformation coefficient of the sealing ring 10, thereby improving the durability of the sealing ring 10 itself. At the same time, the compression force applied by the second electrical connector 30 on the sealing ring 10 is effectively reduced, so that the rigid requirement for installing the electrical connector is reduced, and the service life of the sealing ring 10 is extended.

[0087] One end of the elastic sealing part 23 is connected to the abutting part 22, and the other end of the elastic sealing part 23 extends in the direction close to the mounting part 1, so that a groove recessed outward is formed on the side of the abutting part 2 towards the mounting part 1. A hollow structure 24 is formed between the abutting part 2 and the mounting part 1 through the groove, and the groove communicates with the outside through an opening 25. By having a groove on the abutting part 2 and the elastic sealing part 23 extending in the direction close to the mounting part 1, when the elastic sealing part 23 abuts against the mounting part 1, the abutting part 22 has not yet come into contact with the mounting part 1, ensuring that a sealed hollow cavity 3 is formed when the sealing ring 10 is in a sealed state, enabling the sealing ring 10 to always act on the second electrical connector 30, improving the sealing effect of the electrical connector; and increasing the permanent deformation coefficient of the sealing ring 10, thereby improving the durability of the sealing ring 10 itself; effectively reducing the compression force exerted by the second electrical connector 30 on the sealing ring 10, thereby reducing the rigid requirement for installing the electrical connector and prolonging the service life of the sealing ring 10. At the same time, the overall structure is simple, easy to process and manufacture, and the production cost is reduced.

[0088] The abutting part 2 further includes a second protruding part 27, and the second protruding part 27 can be connected to the outer side in the radial direction of the abutting part 2 and extend outwardly. The second protruding part 27 can also be connected to the inner side in the radial direction of the abutting part 2 and extend inwardly, and the second protruding part 27 abuts against the second electrical connector 30. That is, the second protruding part 27 and the first protruding part 26 are located on different sides of the abutting part 2. The abutting part 2 extends and protrudes radially through the second protruding part 27 and abuts against the second electrical connector 30, so that a radial sealing effect is achieved between the sealing ring 10 and the second electrical connector 30, increasing the sealing ability of the sealing ring 10 and further improving the sealing performance of the electrical connector. Among them, the abutting part 22, the first protruding part 26 and the second protruding part 27 are all embedded in the annular groove 301, and the first protruding part 26 and the second protruding part 27 abut against the inner wall surface of the annular groove 301. The annular groove 301 includes a bottom wall facing the first protruding part 26 and a side wall perpendicular to the bottom wall. When the abutting part 22 is embedded in the annular groove 301, the first protruding part 26 abuts against the bottom wall of the annular groove 301, and the second protruding part 27 abuts against the side wall of the annular groove 301, realizing the axial and radial sealing between the sealing ring 10 and the second electrical connector 30, and improving the sealing effect of the first electrical connector 20 and the second electrical connector 30.

[0089] The mounting component 1 includes a fixing portion 11, a sleeve portion 12, and a floating portion 13. The abutting component 2 is connected to the floating portion 13. The fixing portion 11 and the floating portion 13 are respectively connected to two ends of the sleeve portion 12, and an annular groove for sleeving and connecting to the first electrical connector 20 is formed among the fixing portion 11, the sleeve portion 12, and the floating portion 13. The fixing portion 11 is used for mounting and connecting to the fixing component of the first electrical connector 20, the floating portion 13 is used for mounting and connecting to the floating component of the first electrical connector 20, and the abutting component 2 is connected to the floating portion 13, so that the abutting component 2 abuts against the second electrical connector 30 and realizes floating connection. During use, even if there is a certain deviation in the second electrical connector 30, stable sealing with the abutting component 2 can be achieved, thereby improving the sealing effect of the electrical connector. At the same time, two ends of the sleeve portion 12 are connected to the fixing portion 11 and the floating portion 13, so that the annular groove is sleeved and connected to the first electrical connector 20, and the first electrical connector 20 is wrapped inside by the annular groove, and the waterproof sealing effect is better.

[0090] Embodiment 2

[0091] As Figure 7 shown, the same parts of the sealing ring 10 in this Embodiment 2 and Embodiment 1 will not be repeated, and only the differences will be described. In this Embodiment 2, the connecting portion 21, the abutting portion 22, and the elastic sealing portion 23 are of a continuous arc structure. When the first electrical connector 20 and the second electrical connector 30 are electrically connected, by using the connecting portion 21, the abutting portion 22, and the elastic sealing portion 23 of a continuous arc structure for the abutting component 2, the internal space of the sealed hollow cavity 3 formed when the elastic sealing portion 23 seals and abuts against the mounting component 1 is larger, so that the compression stroke of the sealing ring 10 is large, thereby further reducing the compression force applied by the second electrical connector 30 to the sealing ring 10, reducing the thrust of the second electrical connector 30 on the sealing ring 10 and the first electrical connector 20, thereby reducing the rigid requirement for mounting and setting the electrical connector, and prolonging the service life of the sealing ring 10; at the same time, during the compression process, the pressure received by the sealing ring 10 is balanced and the stability is higher.

[0092] In the second embodiment, the mounting component 1 further includes a limiting portion 14. The connecting portion 21 and the limiting portion 14 are respectively connected to the upper end and the lower end of the same side of the floating portion. The elastic sealing portion 23 is located between the connecting portion 21 and the limiting portion 14. When the elastic sealing portion 23 abuts against the floating portion 13, the limiting portion 14 restricts the elastic sealing portion 23 from moving along the direction away from the connecting portion 21 on the surface of the floating portion 13. By providing a limiting portion 14 inside the floating portion 13, the limiting portion 14 is located at one end of the floating portion 13 away from the connecting portion 21. When the elastic sealing portion 23 abuts against the floating portion 13, the limiting portion 14 is located below the elastic sealing portion 23. The limiting portion 14 blocks and restricts the elastic sealing portion 23 from moving downward on the surface of the floating portion 13, effectively avoiding affecting the sealing effect and having higher stability.
