The opening makes it possible to process and manufacture the hollow structure inside the sealing ring, thereby realizing the feasibility of production and reducing production costs; 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 avoiding the sealing ring from being pulled out by vacuum when opened and damaging the sealing ring, thereby increasing the service life of the sealing ring and improving the sealing reliability of the electrical connector.

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

[0015] In the present solution, the above-mentioned structural form is adopted, and the gap between the elastic sealing part and the mounting component is smaller than the axial dimension of the hollow structure along the sealing ring, so that during the movement, the elastic sealing part will first abut against the mounting component while the inner wall surface of the abutting part does not abut against the mounting component, and the elastic sealing part will close the opening to form a sealed hollow cavity, and 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; the sealing 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, thereby improving the durability of the sealing ring itself; at the same time, during the compression process, the sealing hollow cavity can reduce the compression amount of the material of the sealing ring, effectively reduce the compression force applied 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 requirements for installing and setting the electrical connector and extending the service life of the sealing ring.

[0019] In this solution, the above-mentioned structural form is adopted, and the first protrusion seals against the second electrical connector through the spherical surface, and the spherical surface adopts an arc structure for contact and abutment, thereby further improving the sealing effect between the abutting component and the second electrical connector.

[0020] Preferably, there are a plurality of the first protrusions, and the plurality of the first protrusions are arranged at intervals, so that a recessed groove is formed between any two adjacent first protrusions.

At the same time, a recessed groove is formed between any two adjacent first protrusions. When the second electrical connector abuts against the two adjacent first protrusions, a sealing cavity is formed between the two adjacent first protrusions through the recessed groove. The sealing cavity plays a role in supplementing the sealing compression in the dynamic compression contact, further improving the sealing effect of the electrical connector, improving the durability of the sealing ring itself, extending the service life of the sealing ring, and reducing the rigidity requirements for the installation setting of the electrical connector.

[0022] Preferably, the elastic sealing portion is located on the inner side of the connecting portion, the plurality of first protrusions are arranged at intervals along the radial direction of the sealing ring, and the distance between the plurality of first protrusions and the second electrical connector gradually decreases from outside to inside along the radial direction of the sealing ring.

[0023] In this solution, the above-mentioned structural form is adopted. When the first electrical connector and the second electrical connector are close to each other, the first protrusion from the innermost side to the outermost side abuts against the second electrical connector layer by layer, thereby achieving a multi-level sealing effect of the sealing ring and the second electrical connector, and effectively preventing air from mixing in the middle and affecting the sealing effect. At the same time, the elastic sealing part will first close the opening to form a sealed hollow cavity through the innermost first protrusion. Through the sealed hollow cavity, the sealing ring always forms a sealing thrust on the first electrical connector and the second electrical connector, thereby improving the sealing effect of the electrical connector; and effectively reducing the compression force applied by the second electrical connector on the sealing ring, thereby reducing the rigidity requirements 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 by sealing the hollow cavity, thereby improving the durability of the sealing ring itself.

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

[0025] In the present solution, the above-mentioned structural form is adopted. In the process of the abutting portion and the second electrical connector abutting each other, the innermost first protrusion is first in contact with the second electrical connector, and then the elastic sealing portion and the mounting component are abutted against each other, the opening is closed, and finally the outermost first protrusion is abutted against the second electrical connector, so that the abutting portion and the second electrical connector are always kept in an extrusion state, thereby improving the sealing effect between the first electrical connector and the second electrical connector.

[0027] In this solution, the above-mentioned structural form is adopted, so that when the elastic sealing part and the installation component are abutted against each other, there is no contact and abutment between the abutting part and the installation component, which ensures that a sealed hollow cavity is formed in the sealing ring when in a sealed state, so that the sealing ring always exerts force on the second electrical connector, thereby 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 applied by the second electrical connector on the sealing ring, thereby reducing the rigidity requirements for installing the electrical connector, and extending the service life of the sealing ring. At the same time, the overall structure is simple, the processing and manufacturing are convenient, and the production cost is reduced.

[0028] Preferably, the abutment component also includes a second protrusion, which is connected to the radially outer side of the abutment and extends outwardly, and / or the second protrusion is connected to the radially inner side of the abutment and extends inwardly, and the second protrusion abuts against the second electrical connector.

[0031] In this solution, the above structure is adopted so that the abutting component abuts against the second electrical connector and realizes floating connection. Even if there is a certain deviation of the second electrical connector during use, a stable seal between the abutting component and the second electrical connector can be achieved, thereby improving the sealing effect of the electrical connector. The first electrical connector is wrapped inside the annular groove, and the waterproof sealing effect is better.

[0033] In the present scheme, the above-mentioned structural form is adopted, and the abutment component adopts a connecting portion, an abutment portion and an elastic sealing portion as a continuous arc structure. The internal space of the sealed hollow cavity formed by the elastic sealing portion when the sealing abuts against the mounting component is relatively large, so that the compression stroke of the sealing ring is large, thereby further reducing the compression force applied 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 requirements for installing the electrical connector and extending the service life of the sealing ring; at the same time, the pressure on the sealing ring is balanced during the compression process, and the stability is higher.

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

[0073] Example 1

[0074] like Figures 1 to 6 As shown, an embodiment of the utility model discloses an electrical connector, which can be installed on an electric vehicle, a battery pack or 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 component 1 and abutting component 2, the mounting component 1 is used to be mounted and connected on the first electrical connector 20, the first electrical connector 20 is used to cooperate with the second electrical connector 30 to achieve electrical connection, one side of the abutting component 2 is connected to the mounting component 1, and the other side of the abutting component 2 is used to abut 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 component 2 and the mounting component 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 and the second electrical connector 30 are electrically connected, the sealing ring 10 will abut 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. The sealing hollow cavity 3 allows the sealing ring 10 to generate a supporting force during the process of deformation under force, and always forms a sealing thrust on the first electrical connector 20 and the second electrical connector 30. 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 sealing hollow cavity 3, so that the sealing ring 10 can always act on the second electrical connector 30, thereby improving the sealing effect of the electrical connector.

[0076] In addition, the sealing hollow cavity 3 can increase the deformation compression space of the sealing ring 10, increase the compression ratio of the sealing ring 10, and improve the permanent deformation coefficient of the sealing ring 10, thereby improving the durability of the sealing ring 10 itself; at the same time, the sealing ring 10 always exerts force on the first electrical connector 20 and the second electrical connector 30 during the deformation process. During the compression process, the sealing hollow cavity 3 can reduce the compression amount of the material of the sealing ring 10, thereby effectively reducing the compression force applied 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 rigidity requirements for installing 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] like Figure 2 and Figure 3 As shown, an annular groove 301 is provided on the side of the second electrical connector 30 facing the first electrical connector 20, and the abutting component 2 is embedded in the annular 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 annular groove 301, thereby further improving the sealing effect of the electrical connector and providing higher safety. At the same time, the annular groove 301 will limit the abutting component 2, effectively preventing the sealing ring 10 from offsetting and misaligning the abutting component 2 during use, further improving the stability of the electrical connector.

[0078] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the abutment component 2 includes a connecting portion 21, an abutment portion 22 and an elastic sealing portion 23 which are connected in sequence, the connecting portion 21 is connected to the mounting component 1, a hollow structure 24 is formed between the abutment portion 22 and the mounting component 1, the abutment portion 22 abuts against the second electrical connector 30 to drive the elastic sealing portion 23 to move in a direction approaching or away from the mounting component 1 and has an initial state and a sealing state; in the initial state, an opening 25 connected to the hollow structure 24 is formed between the elastic sealing portion 23 and the mounting component 1; in the sealing state, the elastic sealing portion 23 seals against the mounting component 1 to form a sealed hollow cavity 3 between the abutment component 2 and the mounting component 1.

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

[0080] When the electrical connector is in use, the first electrical connector 20 and the second electrical connector 30 are connected or disconnected to switch between the sealed state and the initial state. The inner part of the abutting component 2 has a hollow structure 24, and an opening 25 at one end. The opening 25 enables the hollow structure 24 to be processed and manufactured in 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, they will automatically return to the initial state, effectively avoiding the vacuum pulling of the sealing ring 10 when opening and damaging the sealing ring 10, thereby increasing 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 portion 23 and the mounting component 1 is smaller than the axial dimension of the hollow structure 24 along the sealing ring 10. In the process of connecting the second electrical connector 30 with the first electrical connector 20, the second electrical connector 30 applies abutting force on the abutting component 2, so that the abutting portion 22 and the elastic sealing portion 23 both move in the direction close to the mounting component 1. The gap between the elastic sealing portion 23 and the mounting component 1 is smaller than the axial dimension of the hollow structure 24 along the sealing ring 10, so that in the process of movement, the elastic sealing portion 23 will first abut against the mounting component 1 while the inner wall surface of the abutting portion 22 does not abut against the mounting component 1. The elastic sealing portion 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 contacts the first electrical connector 20 and the second electrical connector 20 through the sealed hollow cavity 3. The second electrical connector 30 forms a sealing thrust, thereby effectively enhancing the sealing effect of the sealing ring 10; the sealing hollow cavity 3 can increase the deformation compression space of the sealing ring 10, increase the compression ratio of the sealing ring 10, and improve the permanent deformation coefficient of the sealing ring 10, thereby improving the durability of the sealing ring 10 itself; at the same time, during the compression process, the sealing hollow cavity 3 will be able to reduce the compression amount of the material of the sealing ring 10, effectively reducing the compression force applied 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 rigidity requirements for installing the electrical connector and extending the service life of the sealing ring 10.

[0082] The abutting component 2 further includes a first protrusion 26, one end of which is connected to the side of the abutting component 22 facing away from the mounting component 1, and the other end of the first protrusion 26 extends outwardly along the axial direction of the sealing ring 10 and is used to abut against the second electrical connector 30. The first protrusion 26 is arranged on the abutting component 22 and extends outwardly along the axial direction of the sealing ring 10, so that the abutting component 2 and the second electrical connector 30 abut against each other through the first protrusion 26 to seal, thereby further improving the sealing effect between the abutting component 2 and the second electrical connector 30.

[0083] The end surface 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 seals against the second electrical connector 30 through the spherical surface 261, and the spherical surface 261 contacts and abuts with an arc structure, thereby further improving the sealing effect between the abutting component 2 and the second electrical connector 30.

[0084] There are multiple first protrusions 26, 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 abut against the second electrical connector 30 at the same time, and multiple seals will be formed through the multiple first protrusions 26, further improving the sealing 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 the 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 plays a role in supplementing the sealing compression in the dynamic compression contact, further improving the sealing effect of the electrical connector, improving the durability of the sealing ring 10 itself, extending the service life of the sealing ring 10, and reducing the rigidity requirements for the installation of the electrical connector.

[0085] The elastic sealing portion 23 is located on the inner side of the connecting portion 21, and the plurality of first protrusions 26 are arranged at intervals along the radial direction of the sealing ring 10, and the distance between the plurality of first protrusions 26 and the second electrical connector 30 gradually decreases from the outside to the inside along the radial direction of the sealing ring 10. By arranging the elastic sealing portion 23 on the inner side of 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 protrusions 26 and the second electrical connector 30 gradually decreases from the outside to the inside along the radial direction of the sealing ring 10, and the plurality of first protrusions 26 adopt a stepped contact, that is, the innermost first protrusion 26 first contacts and abuts against the second electrical connector 30, that is, the first protrusion 26 closest to the axis of the sealing ring 10 first contacts and abuts against the second electrical connector 30, and the outermost first protrusion 26 contacts and abuts against the second electrical connector 30 last, that is, the first protrusion 26 farthest from the axis of the sealing ring 10 last contacts and abuts against the second electrical connector 30. The second electrical connector 30; the innermost first protrusion 26, in the process of contacting and abutting against the second electrical connector 30, will drive the elastic sealing part 23 to move in the direction of approaching the mounting component 1 and abut against the mounting component 1 first. In the process of the first electrical connector 20 and the second electrical connector 30 approaching each other, the innermost first protrusion 26 to the outermost first protrusion 26 abut against the second electrical connector 30 layer by layer, so as to achieve the multi-level sealing effect of the sealing ring 10 and the second electrical connector 30, and effectively avoid the air mixed in the middle and affect the sealing effect. At the same time, the innermost first protrusion 26 will first make the elastic sealing part 23 close the opening 25 to form a sealed hollow cavity 3, and the sealing hollow cavity 3 makes the sealing ring 10 always form a sealing thrust on the first electrical connector 20 and the second electrical connector 30, thereby 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 rigidity requirements for installing and setting the electrical connector, and extending the service life of the sealing ring 10. At the same time, the sealing ring 10 seals the hollow cavity 3 to increase the permanent deformation coefficient of the sealing ring 10 , thereby improving the durability of the sealing ring 10 itself.

[0086] Among them, in the initial state, the axial spacing between the outermost first protrusion 26 and the innermost first protrusion 26 along the sealing ring 10 is not less than the gap of the opening 25 between the elastic sealing part 23 and the mounting component 1. In the process of mutual connection between the second electrical connector 30 and the first electrical connector 20, the second electrical connector 30 will first contact and abut against the innermost first protrusion 26, and drive the elastic sealing part 23 to move in the direction close to the mounting component 1, and the axial spacing between the outermost first protrusion 26 and the innermost first protrusion 26 along the sealing ring 10 is not less than the gap of the opening 25 between the elastic sealing part 23 and the mounting component 1, that is, in the process of mutual abutment between the abutting part 22 and the second electrical connector 30, the innermost first protrusion 26 first contacts the second electrical connector 30, and then the elastic sealing part 23 and the mounting component 1 abut against each other, and the opening 25 between the elastic sealing part 23 and the mounting component 1 is moved. 5 is closed, and finally the outermost first protrusion 26 abuts against the second electrical connector 30, so that the abutting portion 22 and the second electrical connector 30 are always kept in a squeezed state, thereby 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-mentioned gap size, in the process of the abutting portion 22 and the second electrical connector 30 separating from each other, the outermost first protrusion 26 is first separated from the second electrical connector 30, and then the elastic sealing portion 23 is separated from the mounting component 1, and finally the innermost first protrusion 26 is separated from the second electrical connector 30, so that the first electrical connector 20 and the second electrical connector 30 are easier to separate. When the elastic sealing part 23 and the mounting component 1 are in contact with each other, the second electrical connector 30 does not exert a force on the outermost first protrusion 26. After the elastic sealing part 23 closes the opening 25 to form the sealed hollow cavity 3, the second electrical connector 30 exerts a force on the outermost first protrusion 26, so that a sealed hollow cavity 3 has been formed in the sealing ring 10 and the force is always exerted on the second electrical connector 30, thereby 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 exerted by the second electrical connector 30 on the sealing ring 10 is effectively reduced, thereby reducing the rigidity requirements for installing the electrical connector and extending the service life of the sealing ring 10.

[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 component 1, so that the side of the abutting part 2 facing the mounting component 1 has a groove that is concave outward. A hollow structure 24 is formed between the abutting part 2 and the mounting component 1 through the groove, and the groove is connected to the outside through the 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 component 1, when the elastic sealing part 23 and the mounting component 1 abut against each other, there is no contact and abutment between the abutting part 22 and the mounting component 1, ensuring that a sealed hollow cavity 3 is formed in the sealing ring 10 in the sealed state, so that the sealing ring 10 always acts on the second electrical connector 30, thereby 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 applied by the second electrical connector 30 on the sealing ring 10, thereby reducing the rigidity requirements for installing and setting the electrical connector, and extending the service life of the sealing ring 10. At the same time, the overall structure is simple, the processing and manufacturing are convenient, and the production cost is reduced.

[0088] The abutting component 2 also includes a second protrusion 27, which can be connected to the radially outer side of the abutting component 22 and extend outwardly. The second protrusion 27 can also be connected to the radially inner side of the abutting component 22 and extend inwardly, and the second protrusion 27 abuts against the second electrical connector 30. That is, the second protrusion 27 and the first protrusion 26 are located on different sides of the abutting component 22, and the abutting component 2 protrudes radially and abuts against the second electrical connector 30 through the second protrusion 27, so that a radial sealing effect is achieved between the sealing ring 10 and the second electrical connector 30, the sealing ability of the sealing ring 10 is increased, and the sealing of the electrical connector is further improved. Among them, the abutting component 22, the first protrusion 26 and the second protrusion 27 are all embedded in the annular groove 301, and the first protrusion 26 and the second protrusion 27 abut against the inner wall surface of the annular groove 301. The annular groove 301 includes a bottom wall directly opposite to the first protrusion 26, and a side wall perpendicular to the bottom wall. When the abutment portion 22 is embedded in the annular groove 301, the first protrusion 26 abuts against the bottom wall of the annular groove 301, and the second protrusion 27 abuts against the side wall of the annular groove 301, thereby achieving axial and radial sealing between the sealing ring 10 and the second electrical connector 30, thereby improving the sealing effect of the first electrical connector 20 and the second electrical connector 30.

[0089] The mounting component 1 includes a fixed portion 11, a sleeve portion 12, and a floating portion 13. The abutting component 2 is connected to the floating portion 13. The fixed portion 11 and the floating portion 13 are respectively connected to the two ends of the sleeve portion 12, and an annular groove for sleeve connection to the first electrical connector 20 is formed between the fixed portion 11, the sleeve portion 12, and the floating portion 13. The fixed portion 11 is used to be installed and connected to the fixed component of the first electrical connector 20, the floating portion 13 is used to be installed and connected 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 a floating connection. During use, even if there is a certain deviation in the second electrical connector 30, a stable seal can be achieved between the abutting component 2, thereby improving the sealing effect of the electrical connector. At the same time, the two ends of the sleeve portion 12 are connected to the fixed 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] Example 2

[0091] like Figure 7 As shown, the same parts of the sealing ring 10 of the second embodiment and the first embodiment will not be repeated, and only the differences will be described. In the second embodiment, the connecting portion 21, the abutting portion 22 and the elastic sealing portion 23 are continuous arc structures. When the first electrical connector 20 and the second electrical connector 30 are electrically connected, the connecting portion 21, the abutting portion 22 and the elastic sealing portion 23 are continuous arc structures by the abutting component 2. When the elastic sealing portion 23 is sealed against the mounting component 1, the internal space of the sealed hollow cavity 3 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 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 rigidity requirements for installing the electrical connector and extending the service life of the sealing ring 10; at the same time, the pressure on the sealing ring 10 during the compression process 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 limits the elastic sealing portion 23 from moving on the surface of the floating portion 13 in a direction away from the connecting portion 21. By arranging the limiting portion 14 on the inner side of 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 limits the elastic sealing portion 23 from moving downward on the surface of the floating portion 13, effectively avoiding the sealing effect and achieving higher stability.
