Description

Technical Field

[0001] This invention relates to a sealing ring, a sealing assembly, an electrical connector, and an electric vehicle. Background Technology

[0002] Existing electric vehicles include a battery-side electrical connector mounted on the battery pack and a vehicle-side electrical connector mounted on the vehicle frame. When the battery pack is mounted on the vehicle frame, the battery-side and vehicle-side electrical connectors are electrically connected to provide power to the electric vehicle. Both the battery-side and vehicle-side electrical connectors are equipped with sealing connectors to achieve a sealed connection. In the prior art, the end face of the sealing ring has insufficient sealing compression size, poor compression lip guidance, a large opening at the sealing end, and thin sealing abutment parts on both sides of the opening. During sealing connection, the abutment parts are prone to outward flipping, leading to sealing failure. Furthermore, the effective sealing pressure is insufficient, resulting in poor sealing performance and poor fault tolerance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect of the sealing ring in the prior art that is prone to outward flipping, which leads to sealing failure, and to provide a sealing ring and an electrical connector.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A sealing ring, wherein one end face of the sealing ring is provided with a first abutting portion and a second abutting portion, the first abutting portion is arranged around the second abutting portion, a first groove is provided between the first abutting portion and the second abutting portion, and the thickness of the first abutting portion is greater than the thickness of the second abutting portion;

[0006] Along the axial direction of the sealing ring, the end of the first abutment portion protrudes beyond the end of the second abutment portion.

[0007] In this solution, the sealing ring abuts against the component to be sealed through the first and second abutting parts, thereby improving the reliability of the seal. Furthermore, the first groove between the first and second abutting parts allows for deformation allowance for the abutting seal, resulting in a tighter seal. Additionally, the thickness of the first abutting part is greater than that of the second abutting part, and its end protrudes beyond the end of the second abutting part, which increases the sealing compression size and improves the guiding nature of the compression lip, thus preventing outward turning and sealing failure. Moreover, the overall sealing surface of the first and second abutting parts is conducive to compression, avoiding redundant deformation of the sealing ring and improving safety.

[0008] Preferably, the first abutting portion has a first surface facing the first groove, and the second abutting portion has a second surface facing the first groove, both the first surface and the second surface extending outward in the axial direction of the sealing ring.

[0009] In this design, both the first and second surfaces extend toward the opening of the sealing ring, which allows the first and second abutting parts to be squeezed toward the inside of the sealing ring when the sealing deformation occurs, further preventing them from turning outward.

[0010] Preferably, the first abutting portion has a third surface away from the first groove, and the angle between the third surface and the plane of symmetry of the sealing ring is smaller than the angle between the first surface and the plane of symmetry.

[0011] In this design, the angle between the third surface and the plane of symmetry is smaller than the angle between the first surface and the plane of symmetry. When the third surface abuts against the plane of symmetry, the first abutting part can be squeezed and deformed towards the inside of the sealing ring, thus preventing the first abutting part from turning outward and causing the seal to fail.

[0012] Preferably, there is an arc transition surface between the first surface and the third surface, the arc transition surface being used for sealing and contact.

[0013] In this solution, the sealing and abutment are achieved through a circular arc transition surface, which allows for uniform force distribution and improves sealing performance.

[0014] Preferably, the radius of the arc transition surface near the first surface is smaller than the radius of the arc near the third surface.

[0015] In this solution, with the above structure, when the first abutting part abuts against the sealing surface, the arc surface near the first surface abuts against the sealing surface first, which has a large force-bearing area and small force; and can guide the deformation direction inward, thereby improving the sealing effect.

[0016] Preferably, the second abutment portion has a fourth surface away from the first groove, and the fourth surface has a second groove, which is used to reserve a sealing deformation allowance.

[0017] In this design, the second groove can provide a sealing deformation allowance for the second abutment part, thereby improving the sealing effect of the second abutment part.

[0018] Preferably, the sealing ring includes a fixed part, a ring sleeve part, and a floating part. The fixed part and the floating part are respectively connected to the two ends of the ring sleeve part, and an annular groove is formed between the fixed part, the ring sleeve part, and the floating part. The annular groove is used to fit the first component and the second component.

[0019] Both the first abutting part and the second abutting part are disposed on the outer side wall of the floating part, and both the first abutting part and the second abutting part are used to abut against the third component.

[0020] In this design, the sealing ring wraps around both the first and second components, resulting in better waterproofing. Furthermore, the first and second abutting parts further enhance the sealing effect with the third part.

[0021] Preferably, the inner wall of the fixed part is provided with a first clip for connecting the first component; the inner wall of the floating part is provided with a second clip for connecting the second component.

[0022] In this solution, the first and second clips effectively strengthen the connection between the sealing ring and the vehicle end fixing plate and the vehicle end floating plate, thereby improving the stability of the sealing ring connection.

[0023] Preferably, the second card has a reinforcing portion that extends along the circumferential direction of the second card.

[0024] In this design, the reinforcing material has a higher hardness compared to the sealing ring material. By incorporating a reinforcing part within the second clamping member, it avoids affecting the compression seal formation of the first and second abutment parts of the sealing ring. Furthermore, it enhances the overall strength of the second clamping member, resulting in a more stable connection between the sealing ring and the second component, preventing partial detachment. When the second component is connected to other components for compression sealing, the reinforcing part prevents the sealing ring from separating from the second component during this process, making the connection between the second component and other components more reliable and improving the sealing effect.

[0025] Preferably, the floating part is provided with a positioning member, one end of which is connected to the inner wall surface of the annular groove, and the other end of which extends away from the inner wall surface of the annular groove. The positioning member is used to match and fit the second component.

[0026] In this design, the positioning element restrains the floating part, effectively preventing it from detaching and improving the stability of the structural connection between the sealing ring and the component. Additionally, the positioning element also enhances the bearing strength of the abutment part.

[0027] Preferably, the fixing part is provided with a plurality of protrusions, which are located on the outer side wall of the annular groove.

[0028] In this design, the protrusion acts as a sealant, effectively improving the sealing and waterproofing performance of the sealing ring.

[0029] A sealing assembly, characterized in that the sealing assembly includes a sealing ring and a sealing element as described above, the sealing element being disposed on the outer wall of a third component;

[0030] When the third component is connected to the second component fitted inside the sealing ring, the sealing ring abuts against the sealing element to seal the space between the second component and the third component.

[0031] In this solution, the sealing assembly uses the aforementioned sealing ring, which abuts against the third component through the first and second abutting portions to achieve sealing, thereby improving the reliability of the seal. Furthermore, the first groove between the first and second abutting portions allows for deformation allowance for the abutting seal, resulting in a tighter seal. Additionally, the thickness of the first abutting portion is greater than that of the second abutting portion, and its end protrudes beyond the end of the second abutting portion, which increases the sealing compression size and improves the guiding nature of the compression lip, thus preventing outward flipping that could lead to seal failure. Moreover, the overall sealing surface of the first and second abutting portions facilitates compression, avoids redundant deformation of the sealing ring, and improves safety.

[0032] Preferably, the seal includes a vertical abutment surface, the third component includes an inclined abutment surface, the first abutment portion abuts against the vertical abutment surface, and the second abutment portion abuts against the inclined abutment surface.

[0033] In this design, the first and second abutting parts can abut against different surfaces of the third component, thereby further improving the sealing effect. Furthermore, the vertical abutting surface and the inclined abutting surface are two surfaces of the third component in different directions, allowing the first and second abutting parts to abut against the third component from different directions, resulting in a tighter seal between the sealing ring and the third component.

[0034] Preferably, the second surface of the second abutting part abuts against the inclined abutting surface.

[0035] Preferably, the inner wall of the floating part of the sealing ring and the surface of the sealing member facing the third component are provided with retaining members, and at least one retaining member is provided with a reinforcing part.

[0036] An electrical connector includes a sealing ring as described above; or, includes a sealing assembly as described above; the electrical connector further includes a first part and a second part; the sealing ring is sleeved on the first part and the second part.

[0037] In this solution, the electrical connector uses the aforementioned sealing ring, which abuts against the component to be sealed via the first and second abutting portions to achieve sealing, thereby improving the reliability of the seal. Furthermore, the first groove between the first and second abutting portions allows for deformation allowance during sealing, resulting in a tighter seal. Additionally, the thickness of the first abutting portion is greater than that of the second abutting portion, and its end protrudes beyond the end of the second abutting portion, increasing the sealing compression size and improving the guiding nature of the compression lip, thus preventing outward flipping and sealing failure. Moreover, the overall sealing surface of the first and second abutting portions facilitates compression, avoiding redundant deformation of the sealing ring and improving safety.

[0038] Preferably, the electrical connector further includes a third component and a seal, the third component being used to connect with the second component, and the seal being disposed on the outer wall of the third component and positioned opposite to the sealing ring.

[0039] In this solution, when the third component is connected to the second component, the sealing ring can abut against the sealing element, further improving the sealing effect between the third component and the second component.

[0040] Preferably, the electrical connector further has a connection structure, through which the sealing ring is connected to the second component, and the sealing element is connected to the third component through the connection structure;

[0041] At least one of the connection structure between the sealing ring and the second component, and the connection structure between the seal and the third component, has a reinforcing portion.

[0042] In this solution, by providing reinforcing sections at the connection structure between the sealing ring and the second component, and at the connection structure between the seal and the third component, the sealing connection between the seal and the sealing ring is not affected. Furthermore, the connection strength between the sealing ring and the second component, and / or between the seal and the third component is enhanced, making the connection more stable. This prevents local adhesion and detachment under vacuum conditions between the sealing ring and the second component, and / or between the seal and the third component. The tearing force on the contact surface under vacuum and adhesion is significantly increased, improving the durability and overall performance of the seal. Furthermore, the connection between the second and third components is more reliable, further enhancing the sealing effect.

[0043] Preferably, the reinforcing portion extends along the circumferential direction of the connecting structure.

[0044] In this solution, by adopting the above-mentioned structural form, the connection position at the connection between the sealing ring and the second component can be strengthened as a whole, and / or the connection position at the connection between the seal and the third component can be strengthened as a whole, so that their connection strength is higher and the anti-detachment effect is better.

[0045] Preferably, the connecting structure includes a clip and a slot for receiving the clip, and the reinforcing part is disposed within the clip;

[0046] The connecting structure between the sealing ring and the second component has a locking member and a locking groove, one of which is provided on the inner wall side of the floating part of the sealing ring, and the other is provided on the second component at the position facing the floating part;

[0047] The connecting structure between the seal and the third component includes a clip and a slot, one of which is located on the surface of the seal facing the third component, and the other is located on the third component facing the seal.

[0048] In this solution, through the connection structure of the card and the card slot, the card can be accommodated in the card slot, making the connection more stable. In addition, the card can be made of flexible material. When the card is accommodated in the card slot, the card slot can restrict the card and compress the card in the card slot, so that the reinforcing part can be squeezed in the card and prevent the reinforcing part from coming out of the card. This further improves the anti-detachment ability between the sealing ring and the second component, and between the sealing part and the third component.

[0049] Preferably, one end of the card extends into the card slot, and a limiting groove is provided on the side of the card away from the card slot. A limiting protrusion is provided at the end of the card slot, and the limiting protrusion extends into the limiting groove.

[0050] In this solution, the anti-disengagement performance between the card slot and the card piece is further improved by the cooperation between the limiting groove and the limiting protrusion. This allows the side of the card piece with the reinforced part to be locked in the card slot and prevents it from coming out of the card piece. This makes the connection between the sealing ring and the second component, the sealing element and the third component more stable and improves the overall sealing performance.

[0051] Preferably, the reinforcing part is embedded in the card and is integrally formed with the card;

[0052] Alternatively, the end face of the card facing the card slot may have a receiving groove, and the reinforcing part may be installed in the receiving groove.

[0053] Preferably, the reinforcing portion is arranged circumferentially around the card;

[0054] Alternatively, the reinforcing part may be a split structure, comprising multiple reinforcing bodies arranged sequentially along the circumference of the card.

[0055] Preferably, the end face of the card facing the card slot is provided with a receiving groove, and the width of the opening of the receiving groove is smaller than the width of the bottom of the receiving groove.

[0056] In this solution, by adopting the above-described structural form, the opening is restricted by the slot, which can confine the reinforcing part within the receiving groove, further preventing the reinforcing part from coming out of the receiving groove.

[0057] An electric vehicle includes a sealing ring as described above; or, includes a sealing assembly as described above; or, includes an electrical connector as described above.

[0058] The positive and progressive effects of this invention are as follows: the sealing ring abuts against the component to be sealed through the first abutment portion and the second abutment portion, thereby improving the reliability of the seal; furthermore, the first groove between the first abutment portion and the second abutment portion allows for deformation allowance for the abutment seal, making the seal tighter; and the thickness of the first abutment portion is greater than the thickness of the second abutment portion and its end protrudes beyond the end of the second abutment portion, thereby increasing the sealing compression size and improving the guiding nature of the compression lip, thus preventing outward turning and sealing failure; in addition, the overall sealing surface of the first abutment portion and the second abutment portion is conducive to compression, which can avoid redundant deformation of the sealing ring and improve safety.

[0074] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0075] Example 1

[0076] This invention provides a sealing ring 100, such as... Figure 1 The diagram shown is a schematic representation of the planar structure of the sealing ring 100; as shown... Figure 2 As shown, the end face of one end of the sealing ring 100 is provided with a first abutting portion 110 and a second abutting portion 120. The first abutting portion 110 is arranged around the second abutting portion 120. A first groove 130 is provided between the first abutting portion 110 and the second abutting portion 120, and the thickness of the first abutting portion 110 is greater than the thickness of the second abutting portion 120. Along the axial direction X of the sealing ring 100, the end of the first abutting portion 110 protrudes from the end of the second abutting portion 120.

[0077] Among them, the sealing ring 100 has a structure with a through hole in the center, and the axial direction of the sealing ring 100 is as follows: Figure 2 The direction X is shown in the diagram. In practical implementation, as... Figure 2 As shown, the first abutment portion 110 and the second abutment portion 120 can be protruding structures surrounding the end face of the sealing ring 100, and in the radial direction of the sealing ring 100, the first abutment portion 110 is positioned on the outer side relative to the second abutment portion 120. During the contact between the sealing ring 100 and the component 30 to be sealed, the first abutment portion 110 contacts the component 30 to be sealed earlier than the second abutment portion 120. The first abutment portion 110 is compressed first, and its greater thickness causes it to be compressed inward. Furthermore, the first groove 130 between the first abutment portion 110 and the second abutment portion 120 provides space and allowance for the deformation of the first abutment portion 110, resulting in a tighter seal.

[0078] As a preferred implementation method, such as Figure 3 As shown, the first abutment portion 110 has a first surface 111 facing the first groove 130, and the second abutment portion 120 has a second surface 121 facing the first groove 130. Both the first surface 111 and the second surface 121 extend in the axial direction X of the sealing ring 100. Therefore, when the first abutment portion 110 and the second abutment portion 120 deform during sealing, they can be pressed inwards towards the sealing ring 100, further preventing outward roll-out.

[0079] In specific implementation, such as Figure 3 As shown, the opening of the first groove 130 faces the outside of the sealing ring 100. The angle between the plane containing the first surface 111 and the plane of symmetry containing the axis, and the angle between the plane containing the second surface 121 and the plane of symmetry containing the axis, can each have appropriate angles, so that the first abutment 110 can be compressed inward to prevent it from turning outward; the second abutment 120 can also abut against the corresponding surface of the component 30 to be sealed. Furthermore, as shown, the length of the second surface 121 is greater than the length of the first surface 111. When the first abutment 110 abuts against the component 30 to be sealed, the second surface 121 of the second abutment 120 can further contact the component 410 to be sealed, thereby further improving the sealing effect.

[0080] As a preferred implementation method, such as Figure 3 As shown, the first abutment portion 110 has a third surface 112 away from the first groove 130, and the angle between the third surface 112 and the plane of symmetry of the sealing ring 100 is smaller than the angle between the first surface 111 and the plane of symmetry.

[0081] In specific implementation, such as Figure 3 As shown, the third surface 112 also extends outward in the axial direction X of the sealing ring 100, and the third surface 112 can extend outward in the axial direction X from the end of the annular portion 160 of the sealing ring 100. The angle between the third surface 112 and the plane of symmetry is the first angle 1121, and the angle between the first surface 111 and the plane of symmetry is the second angle 1111, where the first angle 1121 is smaller than the second angle 1111. When it abuts against the sealing ring, the first abutting portion 110 is more easily squeezed and deformed towards the inside of the sealing ring 100, preventing the first abutting portion 110 from turning outward and causing the seal to fail.

[0082] As a preferred implementation method, such as Figure 3 As shown, there is an arc-shaped transition surface 113 between the first surface 111 and the third surface 112, which is used for sealing and contact. This allows for uniform force distribution and improves sealing performance.

[0083] In specific implementation, the arc transition surface 113 can be a continuous arc, that is, the arc transition surface 113 corresponds to a radius value; or it can be a discontinuous arc, that is, the arc transition surface 113 has multiple arc segments, and each segment corresponds to a corresponding radius value. Preferably, the arc transition surface 113 has multiple arc segments.

[0084] In a preferred embodiment, the radius of the arc of the arc transition surface 113 near the first surface 111 is smaller than the radius of the arc near the third surface 112.

[0085] like Figure 3 As shown, the arc transition surface 113 in the figure has at least two arc segments. The arc radius near the first surface 111 is the first radius R1, and the arc radius near the third surface 112 is the second radius R2. The first radius R1 is smaller than the second radius R2. The arc transition can avoid stress concentration and make the force uniform. When the first abutting part 110 abuts against the sealing surface, the arc surface near the first surface 111 preferentially abuts against the sealing surface, which has a large force-bearing area and small force. It can also guide the deformation direction inward and improve the sealing effect.

[0086] As described in the above embodiment, the third surface 112 of the first abutment portion 110 is connected to the annular portion 160 and extends outward in the axial direction X of the sealing ring 100, and the first surface 111 also extends outward in the axial direction X of the sealing ring 100; the third surface 112 and the first surface 111 are transitioned by an arc transition surface 113, which preferably has at least two arc segments; and the radius of the arc segment near the third surface 112 is larger than the radius of the arc segment near the first surface 111, so that in the radial direction of the sealing ring 100, the thickness of the outer side of the first abutment portion is greater than the thickness of the inner side. During the process of the sealing ring 100 contacting the component 30 to be sealed, the arc segment with a larger radius near the third surface 112 of the first abutting part 110 contacts the component 30 to be sealed first. Its thickness is greater than that of the inner side, and its force-bearing performance is better. Furthermore, the third surface 112 extends outward toward the axial direction X of the sealing ring 100, which can guide the sealing ring 100 to be squeezed toward the inner side of the sealing ring 100, thereby improving the overall sealing performance.

[0087] As a preferred implementation method, such as Figure 3 As shown, the second abutment portion 120 has a fourth surface 122 away from the first groove 130, and the fourth surface 122 has a second groove 140, which is used to reserve a sealing deformation allowance. Thus, the sealing effect of the second abutment portion 120 is improved.

[0088] In specific implementation, such as Figure 3 As shown, the second groove 140 is disposed on the fourth surface 122 near the positioning member 172.

[0089] As a preferred implementation method, such as Figure 4 As shown, the sealing ring 100 may further include a fixing part 150, a ring sleeve part 160, and a floating part 170. The fixing part 150 and the floating part 170 are respectively connected to the two ends of the ring sleeve part 160, and an annular groove 180 is formed between the fixing part 150, the ring sleeve part 160, and the floating part 170. The annular groove 180 is used to fit the first component 200 and the second component 300 to realize the connection and fixation between the first component 200 and the second component 300.

[0090] The first abutting part 110 and the second abutting part 120 are both provided on the outer side wall of the floating part 170, and the first abutting part 110 and the second abutting part 120 are both used to abut against the third component 400.

[0091] Thus, the sealing ring 100 wraps around the first component 200 and the second component 300 simultaneously, resulting in better waterproofing; and the first abutment part 110 and the second abutment part 120 can further enhance the sealing effect with the third component 400.

[0092] In practical implementation, the sealing ring 100 can be used to connect the first component 200 and the second component 300, and abut against the third component 400. When applied to the electrical connector 10 between the battery pack and the vehicle body of an automobile, the first component 200 can be a fixed component of the vehicle-side electrical connector, and the second component 300 can be a floating component of the vehicle-side electrical connector. Specifically, the first component 200 can be a fixed plate 210 of the vehicle-side electrical connector, and the second component 300 can be a floating plate 310 of the vehicle-side electrical connector. Further, as... Figure 5 As shown, the fixing plate 210 of the vehicle-end electrical connector can be the housing of the vehicle-end electrical connector, and the second component 300 can be the terminal mounting panel on the vehicle-end electrical connector for mounting high and low voltage terminals. The third component 400 can be the battery-end electrical connector, and the battery-end electrical connector and the vehicle-end electrical connector are connected by a floating electrical connection to ensure the stability of the electrical connection between the battery end and the vehicle-end floating plate 310. The first abutting part 110 and the second abutting part 120 of the sealing ring 100 can increase the sealing compression size and improve the guiding of the compression lip, thereby preventing outward flipping and sealing failure.

[0093] In a preferred embodiment, a first clip 151 is provided on the inner wall of the fixing part 150, and the first clip 151 is used to connect the first component 200; a second clip 171 is provided on the inner wall of the floating part 170, and the second clip 171 is used to connect the second component 300.

[0094] In specific implementation, such as Figure 5 As shown, the first locking member 151 is located inside the sealing ring 100 and extends from the inner wall of the fixing part 150 in a direction away from the inner wall of the fixing part 150, and can be connected to the fixing plate 210 of the vehicle end electrical connector; the second locking member 171 is located inside the sealing ring 100 and extends from the inner wall of the floating part 170 in a direction away from the inner wall of the floating part 170, and can be connected to the floating plate 310 of the vehicle end electrical connector. This effectively strengthens the connection between the sealing ring 100 and the vehicle end fixing plate 210 and the vehicle end floating plate 310, improving the stability of the sealing ring 100 connection.

[0095] As a preferred implementation method, such as Figure 3 and Figure 4 As shown, the floating part 170 is provided with a positioning member 172. One end of the positioning member 172 is connected to the inner wall surface of the annular groove 180, and the other end of the positioning member 172 extends away from the inner wall surface of the annular groove 180. The positioning member 172 is used to match and fit the second component 300. Thus, the positioning member 172 restricts the floating part 170, effectively preventing the floating part 170 from falling off and improving the stability of the structural connection between the sealing ring 100 and the component. In addition, the positioning member 172 can also improve the abutment strength of the abutment part.

[0096] As a preferred implementation method, such as Figure 4 As shown, the fixing part 150 is provided with a plurality of protrusions 152, which are located on the outer side wall of the annular groove 180. This effectively improves the sealing and waterproofing effect of the sealing ring 100.

[0097] In specific implementation, such as Figure 5 As shown, the first abutting part 110 and the second abutting part 120 are provided on the side of the floating part 170 facing the outside of the sealing ring 100, and the sealing ring 100 is an integral structure.

[0098] Example 2

[0099] This embodiment provides a sealing ring 500 with a reinforcing portion 510. This sealing ring 500 can be further reinforced with the reinforcing portion 510 based on the sealing ring 100 provided in Embodiment 1; alternatively, it can be a sealing ring 500 with the reinforcing portion 510 provided in a configuration where the thickness of the first abutting portion 110 is greater than the thickness of the second abutting portion 120, and the end of the first abutting portion 110 protrudes beyond the end of the second abutting portion 120 along the axial direction X of the sealing ring 100. That is, the reinforcing portion 510 is not limited to being provided only in the sealing ring 100 of Embodiment 1; it can also be provided in other sealing rings 500. However, when the reinforcing portion 510 is provided in the sealing ring 100 of Embodiment 1, it can prevent the sealing ring 100 from separating from the second component 300, further improving the sealing effect.

[0100] As a preferred implementation method, such as Figure 7 and Figure 8 As shown, the second clip 171 has a reinforcing part 510 inside, and the reinforcing part 510 extends along the circumferential direction of the second clip 171.

[0101] Compared to the material of the sealing ring 500, the material of the reinforcing part 510 is harder. By providing the reinforcing part 510 within the second clamping member 171, it avoids affecting the compression seal formation of the first and second abutting parts of the sealing ring 500. Furthermore, it strengthens the overall strength of the second clamping member 171, making the connection between the sealing ring 500 and the second component 300 more stable and preventing partial separation between them. When the second component 300 is connected and compressed with other components for sealing, the reinforcing part 510 prevents the sealing ring 500 from separating from the second component 300 during the compression connection, making the connection between the second component 300 and other components more reliable and improving the sealing effect.

[0102] Example 3

[0103] The present invention also provides an electrical connector 10, such as Figure 5As shown, it includes a sealing ring 100 as in Embodiment 1 above; the electrical connector 10 also includes a first component 200 and a second component 300; the sealing ring 100 is sleeved on the first component 200 and the second component 300.

[0104] By employing the aforementioned sealing ring 100, the electrical connector 10 achieves sealing by abutting against the component to be sealed via the first abutting portion 110 and the second abutting portion 120, thereby improving the reliability of the seal. Furthermore, the first groove 130 between the first abutting portion 110 and the second abutting portion 120 allows for a deformation allowance for the abutting seal, resulting in a tighter seal. Additionally, the thickness of the first abutting portion 110 is greater than the thickness of the second abutting portion 120, and its end protrudes beyond the end of the second abutting portion 120, which increases the sealing compression size and improves the guiding nature of the compression lip, thereby preventing outward flipping that could lead to seal failure. Moreover, the overall sealing surface of the first abutting portion 110 and the second abutting portion 120 facilitates compression, preventing redundant deformation of the sealing ring 100 and improving safety.

[0105] like Figure 1 and Figure 5 As shown, the end face of the electrical connector 10 is roughly rectangular, and the sealing ring 100 is also roughly rectangular to fit the electrical connector 10. Correspondingly, in other embodiments, the sealing ring 100 may also be other shapes to fit the end of the electrical connector 10.

[0106] In a specific implementation, the electrical connector 10 includes a vehicle-side electrical connector 11 disposed on the vehicle and a battery-side electrical connector 12 disposed on the battery pack. The sealing ring 100 can be disposed on the end face of the vehicle-side electrical connector 11 or on the end face of the battery-side electrical connector 12. Preferably, it is disposed on the end face of the vehicle-side electrical connector 12, which can make the electrical connection of the vehicle more stable.

[0107] As a preferred implementation method, such as Figure 5 As shown, the electrical connector 10 also includes a third component 400 and a seal 410. The third component 400 is used to connect with the second component 300, and the seal 410 is disposed on the outer wall of the third component 400 and is positioned opposite to the sealing ring 100. Therefore, when the third component 400 is connected to the second component 300, the sealing ring 100 can abut against the seal 410, further improving the sealing connection effect between the third component 400 and the second component 300.

[0108] In specific implementation, such as Figure 5As shown, the second component 300 and the third component 400 are provided with matching poles. When the third component 400 is connected to the second component 300, the pole on the third component 400 is connected to the pole on the second component 300, and at the same time, the sealing ring 100 abuts against the sealing member 410 provided on the outer wall of the third component 400.

[0109] Example 4

[0110] The present invention also provides an electrical connector 10, such as Figure 6 and Figure 7 As shown, it includes a sealing ring 500 as described in Embodiment 2 above. Accordingly, the electrical connector 10 in this embodiment may be based on the electrical connector 10 in Embodiment 3, with a further reinforcement portion 510 provided. However, the reinforcement portion 510 is not limited to being provided only in the electrical connector 10 in Embodiment 3, but may also be provided in other electrical connectors 10.

[0111] In a preferred embodiment, the electrical connector 10 also has a connection structure in which the sealing ring 500 is connected to the second component 300 and the sealing member 410 is connected to the third component 400 through the connection structure; at least one of the connection structure between the sealing ring 500 and the second component 300 and the connection structure between the sealing member 410 and the third component 400 has a reinforcing portion 510.

[0112] like Figure 6 and Figure 7 As shown, the sealing ring 500 is connected to the second component 300 through the first connecting structure 610, and the sealing element 410 is connected to the third component 400 through the second connecting structure 620. At least one of the first connecting structure 610 and the second connecting structure 620 has a reinforcing part 510.

[0113] By providing reinforcing portions 510 at the first connection structure 610 between the sealing ring 500 and the second component 300, and at the second connection structure 620 between the sealing element 410 and the third component 400, the sealing connection between the sealing element 410 and the sealing ring 500 is not affected. Furthermore, the connection strength between the sealing ring 500 and the second component 300, and / or between the sealing element 410 and the third component 400 is enhanced, making the connection more stable. This prevents local adhesion and vacuum adsorption between the sealing ring 500 and the second component 300, and / or between the sealing element 410 and the third component 400, significantly increasing the tearing force on the contact surface under vacuum and adhesion, thus improving the sealing durability and overall performance. Furthermore, the connection between the second component 300 and the third component 400 is more reliable, further improving the sealing effect.

[0114] As a preferred implementation method, such as Figure 8 and Figure 9 As shown, the reinforcing part 510 extends along the circumferential direction of the connecting structure.

[0115] like Figure 8 As shown, the reinforcing portion 510 within the first connecting structure 610 extends along the circumferential direction of the first connecting structure 610; as Figure 9 As shown, the reinforcing portion 510 within the second connecting structure 620 extends along the circumferential direction of the second connecting structure 620. For example... Figure 6 As shown, when the vehicle-side electrical connector 11 and the battery-side electrical connector 12 are connected to each other, the sealing ring 500 and the sealing element 410 abut against each other in the circumferential direction. The pressing force of the abutment is also applied in the circumferential direction. Each reinforcing part 510 can extend in the circumferential direction of its respective connection structure. Thus, the connection position can be strengthened at the connection between the sealing ring 500 and the second component 300, and at the connection between the sealing element 410 and the third component 400, so that their connection strength is higher and the anti-detachment effect is better.

[0116] In a preferred embodiment, the connection structure includes a clip and a slot for receiving the clip, and a reinforcing part 510 is disposed within the clip;

[0117] The connecting structure between the sealing ring 500 and the second component 300 includes a clip and a slot, one of which is provided on the inner wall side of the floating part of the sealing ring 500, and the other is provided on the second component 300 at a position facing the floating part;

[0118] The connection structure between the seal 410 and the third component 400 includes a clip and a slot, one of which is provided on the surface of the seal 410 facing the third component 400, and the other is provided at the position of the third component 400 facing the seal 410.

[0119] Through the connection structure of the card and the slot, the card can be accommodated in the slot, making the connection more stable. In addition, the card can be made of flexible material. When the card is accommodated in the slot, the slot can restrict the card and compress the card in the slot, so that the reinforcing part 510 can be squeezed in the card, preventing the reinforcing part 510 from coming out of the card, and further improving the anti-detachment ability between the sealing ring 500 and the second component 300, and between the sealing member 410 and the third component 400.

[0120] like Figure 7 and Figure 8 As shown, the first connecting structure 610 includes a second locking member 171 and a second locking groove 320 for accommodating the second locking member 171. The second locking member 171 is disposed on the inner wall side of the floating part of the sealing ring 500, and the second locking groove 320 is disposed at the position of the second component 300 facing the floating part. The reinforcing part 510 is disposed within the second locking member 171. Figure 7and Figure 9 As shown, the second connection structure 620 includes a third locking member 413 and a third locking groove 420 for accommodating the third locking member 413. The third locking member 413 is disposed on the surface of the sealing member 410 facing the third component 400, the third locking groove 420 is disposed at the position of the third component 400 facing the sealing member 410, and the reinforcing part 510 is disposed inside the third locking member 413.

[0121] As a preferred implementation method, such as Figure 4 and Figure 7 As shown, one end of the card extends into the card slot, and a limiting groove 630 is provided on the side of the card away from the card slot. A limiting protrusion 640 is provided at the end of the card slot, and the limiting protrusion 640 extends into the limiting groove 630.

[0122] The cooperation between the limiting groove 630 and the limiting protrusion 640 further enhances the anti-disengagement performance between the slot and the card, allowing the side of the card with the reinforcing part 510 to be locked in the slot and prevented from coming out of the card. This makes the connection between the sealing ring 500 and the second component 300, the sealing element 410 and the third component 400 more stable, and improves the overall sealing performance.

[0123] In a preferred embodiment, the reinforcing part 510 is embedded within the clip and integrally formed with the clip. Specifically, the reinforcing part 510 can be embedded as an insert during the manufacturing of the sealing ring 500 or the sealing element 410.

[0124] In another preferred embodiment, the end face of the card facing the card slot is provided with a receiving groove 650, and the reinforcing part 510 is installed in the receiving groove 650.

[0125] In practical implementation, the sealing ring 500 and the sealing element 410 can be made of silicone rubber, and the reinforcing part 510 can be made of a relatively hard material such as steel wire. During processing, the steel wire can be directly embedded during the vulcanization of silicone rubber, or a receiving groove 650 for the steel wire can be left during the vulcanization of the sealing gasket for later insertion. The diameter of the steel wire can be 1.6 to 2 mm, preferably 1.8 mm.

[0126] As a preferred embodiment, the reinforcing part 510 is arranged circumferentially around the card. For example... Figure 8 The diagram shows a partial structural schematic of the sealing ring 500, where the reinforcing portion 510 is separate from the second retaining member 171. When the reinforcing portion 510 is mounted on the second retaining member 171, the annular reinforcing portion 510 can surround the generally rectangular second retaining member 171. Figure 9 As shown, the reinforcing part 510 is separate from the third clip 413. When the reinforcing part 510 is installed on the third clip 413, the annular reinforcing part 510 can also surround the generally rectangular third clip 413.

[0127] In a preferred embodiment, the reinforcing part 510 is a split structure, including multiple reinforcing bodies arranged sequentially along the circumference of the clip. For example... Figure 11 and Figure 12 As shown, the reinforcing part 510 has four reinforcing bodies, which are located at the four sides of the generally rectangular seal 410. Correspondingly, the reinforcing part 510 in the sealing ring 500 can also have a similar structure. This split-type reinforcing part 510 has low processing cost and is easy to manufacture.

[0128] As a preferred implementation method, such as Figure 10 As shown, the end face of the card facing the card slot has a receiving groove 650, and the width of the opening of the receiving groove 650 is smaller than the width of the bottom of the receiving groove 650. The opening is restricted by the card slot, which can confine the reinforcing part 510 within the receiving groove 650, further preventing the reinforcing part 510 from coming out of the receiving groove 650.

[0129] In other embodiments, in addition to the annular reinforcing part 510 or the split reinforcing part 510 described above, local reinforcement can also be achieved by a built-in spring buckle structure to improve sealing performance.

[0130] Combination Figure 5 The diagram shows a cross-sectional view of the electrical connector 10. A reinforcing portion 510 can be provided within the sealing ring 100 and within the sealing member 410 to form... Figure 6The sealing component 20 is included. The electrical connector 10 may include a vehicle-end electrical connector 11 and a battery-end electrical connector 12. The vehicle-end connector 11 has a first component 200 and a second component 300 that can be fitted onto the sealing ring 500. Further, the first component 200 may be a vehicle-end fixed plate 210, and the second component 300 may be a vehicle-end floating plate 310. The battery-end electrical connector 12 may have a third component 400 and a seal 410 disposed on the outer wall of the third component 400. Further, the third component may be a battery-end floating plate. When the vehicle-end connector 11 and the battery-end electrical connector 12 are connected, the end faces formed by the seal 410 and the battery-end floating plate abut against the end face of the sealing ring 500. The sealing ring 500 and the seal 410 are preferably made of flexible materials and will undergo compression deformation during abutment. The second component 300 connected to the sealing ring 500 and the third component 400 connected to the seal 410 can be made of rigid materials. When the sealing ring 500 and the seal 410 are deformed by compression, the reinforcing part 510 can increase the engagement capability of the second slot 320 with the second slot 171 and the engagement capability of the third slot 420 with the third slot 413. This can increase the connection strength between the sealing ring 500 and the second component 300, and the connection strength between the seal 410 and the third component 400, preventing the sealing ring 500 from coming out of the second component 300 and the seal 410 from coming out of the third component 400, thereby improving the sealing effect of the electrical connector 10.

[0131] Example 5

[0132] The present invention also provides a sealing component 20, such as Figure 5 As shown, the sealing assembly 20 includes a sealing ring 100 and a sealing member 410 as described above, with the sealing member 410 disposed on the outer wall of the third component 400.

[0133] When the third component 400 is connected to the second component 300 fitted inside the sealing ring 100, the sealing ring 100 abuts against the sealing element 410 to seal the space between the second component 300 and the third component 400.

[0134] By employing the aforementioned sealing ring 100, the sealing assembly 20 achieves sealing by abutting against the third component 400 through the first abutting portion 110 and the second abutting portion 120, thereby improving the reliability of the seal. Furthermore, the first groove 130 between the first abutting portion 110 and the second abutting portion 120 allows for a deformation allowance for the abutting seal, resulting in a tighter seal. Additionally, the thickness of the first abutting portion 110 is greater than the thickness of the second abutting portion 120, and its end protrudes beyond the end of the second abutting portion 120, which increases the sealing compression size and improves the guiding nature of the compression lip, thereby preventing outward flipping that could lead to seal failure. Moreover, the overall sealing surface of the first abutting portion 110 and the second abutting portion 120 facilitates compression, preventing redundant deformation of the sealing ring 100 and improving safety.

[0135] As a preferred implementation method, such as Figure 5 As shown, the seal 410 includes a vertical abutment surface 411, the third component 400 includes an inclined abutment surface 412, the first abutment portion 110 abuts against the vertical abutment surface 411, and the second abutment portion 120 abuts against the inclined abutment surface 412.

[0136] In specific implementation, such as Figure 5 As shown, the first abutment portion 110 and the second abutment portion 120 can abut against different surfaces of the third component 400. The first abutment portion 110 and the vertical abutment surface 411 form a primary seal between the sealing ring 100 and the third component 400. Based on this primary seal, the second abutment portion 120 and the inclined abutment surface 412 form a secondary seal between the sealing ring 100 and the third component 400, thereby further improving the sealing effect. Furthermore, the vertical abutment surface 411 and the inclined abutment surface 412 are two surfaces of the third component 400 with different directions. The first abutment portion 110 and the second abutment portion 120 can abut against the third component 400 from different directions, making the seal between the sealing ring 100 and the third component 400 even tighter.

[0137] As a preferred implementation method, such as Figure 5 and combined Figure 6 As shown, the second surface 121 of the second abutting part 120 abuts against the inclined abutting surface 412.

[0138] In specific implementation, such as Figure 3 As shown, the length of the second surface 121 of the second abutment portion 120 is greater than the length of the first surface 111 of the first abutment portion 110, so that the first abutment portion 110 can abut against the vertical abutment surface 411, and the second surface 121 of the second abutment portion 120 can abut against the inclined abutment surface 412.

[0139] Example 6

[0140] The present invention also provides a sealing component 20, such as Figure 7 As shown, it includes a sealing ring 500 and a sealing element 410 as described in Embodiment 4 above. Accordingly, the sealing assembly 20 in this embodiment may be based on the sealing assembly 20 in Embodiment 5, further comprising a reinforcing portion 510 within the sealing ring 500 and / or the sealing element 410. However, the reinforcing portion 510 is not limited to being provided only in the sealing assembly 20 in Embodiment 5; it may also be provided in other sealing assemblies 20 to prevent detachment and improve sealing performance.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
