Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a sealing connector cover and connector device. Background Technology

[0002] Vehicle connectors are components used in a vehicle's electrical system to electrically connect two electrical devices. The performance of vehicle connectors directly affects the safety and reliability of the vehicle. Because vehicles experience vibrations and impacts during operation, and are also affected by environmental factors such as rain and dust, vehicle connectors are prone to problems such as loosening, poor contact, and short circuits.

[0003] In related technologies, a vehicle connector is fixedly connected to a fixed part of a vehicle (such as the vehicle body, electrical system housing, or enclosure) via a sealing cover. The sealing cover is annular, and its outer edge connects to the fixed part. The vehicle connector passes through the center of the sealing cover and connects to it, thereby achieving connection between the sealing cover and the fixed part of the vehicle. The part of the sealing cover that contacts the vehicle connector is made of rubber. The inner wall of the sealing cover fits tightly against the circumferential outer wall of the vehicle connector to achieve connection through friction, and also achieves sealing, dustproof, and waterproof effects.

[0004] However, when the vehicle vibrates or is impacted during operation, the vehicle connector and the sealing cover may still move relative to each other, resulting in a high risk of seal failure between the vehicle connector and the sealing cover. Furthermore, the vibration resistance of the vehicle connector needs to be improved. Utility Model Content

[0005] The first objective of this invention is to provide a sealing connection cover to solve the technical problems of easy sealing failure and poor vibration resistance in the prior art.

[0006] The second objective of this invention is to provide a connector device with high sealing performance and vibration resistance.

[0007] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0008] Sealing connection cover, including:

[0009] A first cover body, wherein the first cover body is provided with a first assembly hole;

[0010] The second cover is disposed in the first mounting hole, and the second cover has a second mounting hole. The hole wall of the second mounting hole has a first snap-fit ​​portion, which is configured to snap-fit ​​with the connector body.

[0011] The sealing structure includes a first fixing part, a second fixing part, and a vibration damping part connected to the first fixing part and the second fixing part. The first fixing part is connected to the second cover and is configured to abut against the connector body. The second fixing part is connected to the first cover.

[0012] In one embodiment, the first fixing portion has a first sealing portion protruding from the wall of the second mounting hole, the first sealing portion being configured to abut against the connector body.

[0013] In one embodiment, the longitudinal section of the vibration damping part is wavy, and there is a gap between the vibration damping part and the first cover, and a gap between the vibration damping part and the second cover.

The third fixing part abuts against the first cover, and the fourth engaging part engages with the third engaging part.

[0023] In one embodiment, the first cover has a first surface and a second surface disposed opposite to each other in the thickness direction;

[0024] The third fixing part has a third sealing part that protrudes from the first surface; and / or, the surface of the fourth snap-fit ​​part opposite to the first surface is flush with the second surface.

[0025] The connector device includes a sealing connection cover as described above, and the connector device also includes a connector body. The circumferential sidewall of the connector body is provided with a locking structure that mates with the first locking portion. The connector body passes through the second assembly hole, and the first locking portion is locked into the locking structure.

[0026] The beneficial effects of this utility model are:

[0027] The provided sealing connector cover has a first cover body and a second cover body connected by a sealing structure.

[0058] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0059] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0060] This embodiment provides a sealing connector cover for connecting to the connector body, which can improve the reliability of the connection with the connector body, reduce the risk of sealing failure with the connector body, and also improve vibration resistance.

[0061] For example, such as Figures 1 to 8As shown, the sealing connection cover 10 includes a first cover 1, a second cover 2, and a sealing structure 3. The first cover 1 is used to connect the enclosure 40 of the electrical system, and the second cover 2 is used to connect the connector body 20.

[0062] It should be noted that the sealing cover 10 is used to fix and seal the connector body 20 on a fixed part of a device such as a vehicle or electronic device that requires a connector. This embodiment uses a vehicle-mounted connector 20 as an example, but it is not a limitation. The fixed part of the vehicle can be the electrical system enclosure 40. In this embodiment, the sealing cover 10 is used to fix and seal the connector body 20 to the electrical system enclosure 40, thereby improving the sealing performance of the enclosure 40.

[0063] like Figure 3 As shown, the first cover 1 is annular, that is, the first cover 1 is provided with a first mounting hole 11. The first mounting hole 11 extends through the first cover 1 along the thickness direction of the first cover 1. The edge of the first cover 1 can be connected to the enclosure 40 of the electrical system, and the enclosure 40 of the electrical system has a through hole communicating with the mounting hole for the connector body 20 to pass through.

[0064] In some optional embodiments, the first cover 1 can be made of a metallic or non-metallic material. When the first cover 1 is made of a non-metallic material, it can be made of plastic or other rigid materials, and this embodiment does not limit this.

[0065] It should be noted that a sealing ring or other sealing component may be provided between the first cover 1 and the electrical system enclosure 40 to prevent water or dust from entering the enclosure 40 through the gap between the first cover 1 and the enclosure 40 and the through holes on the enclosure 40, thereby improving reliability.

[0066] like Figure 2 As shown, the second cover 2 is disposed in the central region of the first cover 1, that is, the second cover 2 is disposed in the first mounting hole 11. In this embodiment, the second cover 2 and the first cover 1 are not directly connected, but are connected through a sealing structure 3.

[0067] It should be noted that the second cover 2 being disposed in the first mounting hole 11 can be understood as at least a portion of the second cover 2 being located in the first mounting hole 11, and is not limited to the entire second cover 2 being located in the first mounting hole 11. In one possible embodiment, the thickness of the second cover 2 is greater than the thickness of the first cover 1.

[0068] In addition, the first cover 1 and the second cover 2 can be coaxially arranged, or they can be not coaxially arranged; this embodiment does not limit this.

[0069] In some optional embodiments, the second cover 2 can be made of a metallic or non-metallic material. When the second cover 2 is made of a non-metallic material, it can be made of plastic or other rigid materials, and this embodiment does not limit this.

[0070] like Figure 3 As shown, the second cover 2 is provided with a second mounting hole 21, which is used to assemble the connector body 20. For example, the connector body 20 passes through the second mounting hole 21. In this embodiment, the second mounting hole 21 extends through the second cover 2 along its thickness direction. The wall of the second mounting hole 21 is provided with a first snap-fit ​​portion 22, which is used to snap-fit ​​with the connector body 20 to achieve the connection between the second cover 2 and the connector body 20. Through the snap-fit ​​engagement of the first snap-fit ​​portion 22 with the connector body 20, a detachable connection between the second cover 2 and the connector body 20 is achieved.

[0071] like Figure 1 and Figure 2 As shown, the sealing structure 3 is connected to the first cover 1 and the second cover 2 to achieve the connection between the first cover 1 and the second cover 2. It should be noted that the sealing structure 3 is sealed to the first cover 1; that is, there is no gap between the sealing structure 3 and the first cover 1. There is also no gap between the sealing structure 3 and the second cover 2, making the overall structure formed by the sealing structure 3, the first cover 1, and the second cover 2 relatively sealed.

[0072] In this embodiment, as Figure 1 or Figure 2 As shown, the sealing structure 3 includes a first fixing part 31, a second fixing part 32, and a vibration damping part 33 connected to the first fixing part 31 and the second fixing part 32. The first fixing part 31 and the second fixing part 32 are connected by the vibration damping part 33, so that the vibration damping part 33 is used to buffer the force transmitted from the second fixing part 32 to the first fixing part 31, thereby buffering and canceling the force transmitted from the housing 40 to the connector body 20. This reduces the vibration and impact force on the connector body 20, lowers the risk of the connector body 20 separating from the sealing connection cover 10 due to specific vibrations, and ensures sealing performance.

[0073] The first fixing part 31 is connected to the second cover 2, and the first fixing part 31 is used to abut against the connector body 20 to form a seal. The second fixing part 32 is connected to the first cover 1. In this way, the connection between the sealing structure 3 and the first cover 1 and the second cover 2 can be realized.

[0074] The sealing connection cover 10 provided in this embodiment has a first cover body 1 and a second cover body 2 connected by a sealing structure 3. The second assembly hole 21 of the second cover body 2 is provided with a first snap-fit ​​part 22, which is used to snap-fit ​​with the connector body 20 to improve the connection strength between the second cover body 2 and the connector body 20 and reduce the risk of the connector body 20 rotating or moving relative to the second cover body 2. The first fixing part 31 abuts against the connector body 20 and is connected to the second cover body 2 to reduce the risk of the first fixing part 31 moving or rotating relative to the connector body 20. This allows the sealing connection cover 10 to abut tightly against the connector body 20, thereby achieving a high sealing effect and high reliability between the sealing connection cover 10 and the connector body 20. By providing a vibration damping part 33, the vibration damping of the connector body 20 can be buffered, thereby improving the vibration damping performance of the sealing connection cover 10 and reducing the risk of damage to the connector body 20.

[0075] Furthermore, a sealing structure 3 is provided between the first cover 1 and the second cover 2. The sealing structure 3 is usually made of an elastic material, which allows the relative positions of the first cover 1 and the second cover 2 to be variable. That is, the relative position of the second cover 2 and the housing 40 is variable, which in turn allows the relative position of the connector body 20 and the housing 40 to be variable. Compared with the rigid connection between the connector body 20 and the housing 40, the connector body 20 has stronger vibration resistance, which greatly reduces the risk of damage to the connector body 20 and extends the service life of the connector body 20.

[0076] In addition, in this embodiment, the connector body 20 is engaged with the first snap-fit ​​part 22 and contacts the first sealing part 34, so that the connector body 20 and the sealing connection cover 10 are assembled in a rigid connection and elastic contact manner. While ensuring the sealing effect, it also facilitates the assembly and assembly of the connector body 20 and the sealing connection cover 10.

[0077] In at least one possible implementation, such as Figure 2 As shown, the first fixing part 31 has a first sealing part 34 protruding from the wall of the second mounting hole 21, such as... Figure 15 As shown, the first sealing part 34 is configured to abut against the connector body 20. The connector body 20 is installed in the second mounting hole 21, and the first sealing part 34 protrudes from the second mounting hole 21, so that the first sealing part 34 can fit tightly against the connector body 20, and there is no gap between the first sealing part 34 and the connector body 20. This also eliminates the gap between the sealing cover 10 and the connector body 20, improving the overall sealing performance of the connector body 20, the electrical system housing 40, and the sealing cover 10.

[0078] It is understandable that the first sealing part 34 in this embodiment can extend in a ring shape along the circumference of the second assembly hole 21 so that there is no gap between the connector body 20 and the sealing connection cover 10 in the circumferential direction.

[0079] Optionally, one or more first sealing portions 34 may be provided, and this embodiment is not limited to this. When multiple first sealing portions 34 are provided, the multiple first sealing portions 34 may be spaced apart along the thickness direction of the second cover 2, so that the sealing effect will be effectively enhanced.

[0080] In some optional embodiments, the sealing structure 3 can be made of an elastic material, capable of elastic deformation, thereby achieving high sealing performance. Exemplarily, the material of the sealing structure 3 can be, for example, silicone rubber (VMQ), fluororubber (FKM), nitrile rubber (NBR), ethylene propylene diene monomer (EPDM), chloroprene rubber (CR), polyurethane rubber (PU), acrylate rubber (ACM), polytetrafluoroethylene (PTFE), etc., and this embodiment does not limit this to any particular material.

[0081] In this embodiment, the sealing structure 3 can be an integral structure or a split structure. When the sealing structure 3 is an integral structure, it can have higher integrity and is easier to process and manufacture.

[0082] In at least one possible implementation, the sealing structure 3 and the second cover 2 are snap-fitted together. This arrangement facilitates the connection between the sealing structure 3 and the second cover 2, and also improves the flexibility of the sealing structure 3 and the second cover 2.

[0083] In one possible implementation, the sealing structure 3 and the second cover 2 can be assembled by plastic overmolding, or by interference assembly or mushroom head assembly. This embodiment does not limit the specific assembly method.

[0084] In one embodiment, such as Figure 5 or Figure 6 As shown, the sealing structure 3 further includes a second snap-fit ​​portion 35 disposed on the first fixing portion 31. Optionally, the first fixing portion 31 is annular. Figure 4 As shown, the second cover 2 is provided with a first engaging portion 23 that cooperates with the second engaging portion 35. The first fixing portion 31 abuts against the second cover 2, and the second engaging portion 35 engages with the first engaging portion 23, thereby realizing the engagement between the sealing structure 3 and the second cover 2. The first fixing portion 31 can contact the second cover 2 in a sealing manner.

[0085] In some alternative embodiments, such as Figure 4As shown, the first engaging part 23 can be a hole structure, groove structure, etc. provided on the second cover 2, and the second engaging part 35 can be a protrusion, ridge, etc. provided on the first fixing part 31. The protrusion or ridge is sealed in the hole structure or groove structure to achieve engaging and sealing.

[0086] Of course, it is understandable that the second snap-fit ​​part 35 can also be a hole structure or a groove structure, and the first snap-fit ​​part 23 can be a protrusion or a protrusion strip, as long as snap-fit ​​can be achieved. This embodiment does not limit this.

[0087] It is understandable that the fit between the second snap-fit ​​portion 35 and the first snap-fit ​​portion 23 can be an interference fit to ensure a seal between the second snap-fit ​​portion 35 and the first snap-fit ​​portion 23.

[0088] In this embodiment, the first sealing part 34 may be connected to the first fixing part 31, or the first sealing part 34 may also be connected to the second snap-fit ​​part 35, or the first sealing part 34 may be connected to both the first fixing part 31 and the second snap-fit ​​part 35. This embodiment does not limit this.

[0089] Figures 9 to 14 This is a schematic diagram of the sealing connection cover 10 and the connector body 20 after assembly in this embodiment.

[0090] In some alternative embodiments, please refer to Figure 2 and Figure 12 The outer circumferential surface of the first fixing part 31 is flush with the outer circumferential surface of the second cover 2. This arrangement ensures that the first fixing part 31 does not extend beyond the second cover 2, thus minimizing the material used in the first fixing part 31 while maintaining strong connection between them, thereby reducing the cost of the sealing structure 3. Furthermore, the flush alignment of the outer circumferential surface of the first fixing part 31 with the outer circumferential surface of the second cover 2 also provides space for other structures (such as vibration damping structures and buffer structures).

[0091] Among them, such as Figure 2 or Figure 3 As shown, the circumferential outer surface of the first fixing part 31 is the surface of the first fixing part 31 that is away from the axis of the sealing structure 3, and the axis of the sealing structure 3 is referred to as the first axis Z1. The circumferential outer surface of the second cover 2 is the surface of the second cover 2 that is away from the axis of the second cover 2, and in this embodiment, the axis of the second cover 2 is referred to as the second axis Z2. Optionally, the first axis Z1 and the second axis Z2 may coincide or may not coincide, and this embodiment does not limit this. In this embodiment, the direction of the second axis Z2 is the same as the direction of the first axis Z1.

[0092] In at least one possible implementation, such as Figure 1 and Figure 2As shown, the second cover 2 and the first fixing part 31 have a concave-convex fit structure. Exemplarily, this embodiment provides a second cover 2 and a first fixing part 31, but it is not limited thereto, and can be flexibly adjusted according to needs.

[0093] Optionally, such as Figure 4 As shown, the second cover 2 includes a first connecting portion 24 and a second connecting portion 25 that are interconnected. The first connecting portion 24 and the second connecting portion 25 are arranged along the axial direction of the second cover 2. The first connecting portion 24 and the second connecting portion 25 are offset in a direction perpendicular to the axial direction of the second cover 2, and a first engaging portion 23 is provided on the first connecting portion 24 and / or the second connecting portion 25. In this embodiment, the first connecting portion 24 is closer to the axis of the second cover 2 (i.e., the second axis Z2) than the second connecting portion 25, and a first engaging portion 22 is provided on the first connecting portion 24.

[0094] In one embodiment, such as Figure 4 As shown, the first engaging portion 23 may include a stepped groove 231 and a first hole 232 provided on the second cover 2. The stepped groove 231 may be formed by the mutual cooperation of the first connecting portion 24 and the second connecting portion 25, and the stepped groove 231 faces the connector body 20. The first hole 232 communicates with the stepped groove 231.

[0095] In conjunction with the second cover 2, such as Figure 5 , Figure 6 or Figure 15 As shown, the second latching portion 35 includes a first latching segment 351 and a second latching segment 352 that are connected to each other. The second latching segment 352 is connected between the first latching segment 351 and the first fixing portion 31.

[0096] In some alternative embodiments, the first snap-fit ​​segment 351 and the first fixing part 31 are arranged in the axial direction of the sealing structure 3. The first snap-fit ​​segment 351 and the first fixing part 31 are offset in a direction perpendicular to the axial direction of the sealing structure 3, with the first snap-fit ​​segment 351 being closer to the axis of the sealing structure 3 (i.e., the first axis Z1) than the first fixing part 31.

[0097] In this embodiment, the first snap-fit ​​segment 351 snaps into the stepped groove 231. Furthermore, the first snap-fit ​​segment 351 is provided with a first sealing portion 34 for contacting the connector body 20. The first fixing portion 31 is arranged around the outside of the first connecting portion 24 and contacts the outer surface of the first connecting portion 24 and the surface of the second connecting portion 25 near the first connecting portion 24. The second snap-fit ​​segment 352 snaps into the first hole 232. This arrangement interweaves and misaligns the second snap-fit ​​portion 35 with the second cover 2, forming a concave-convex fit structure, which further improves the connection strength and reliability between the second snap-fit ​​portion 35 and the second cover 2.

[0098] In some alternative embodiments, the first sealing part 34 is a plurality of raised strips provided on the inner wall of the first snap-fit ​​section 351. That is, during the assembly of the second cover 2, the raised strips are compressed and tightly fitted to the outer wall of the second cover 2 to provide sealing and stability.

[0099] To further improve the connection strength between the first latching segment 351 and the first fixing part 31, in some optional embodiments, multiple second latching segments 352 and first holes 232 are provided in a one-to-one correspondence. These multiple second latching segments 352 are spaced apart circumferentially along the first fixing part 31, and each second latching segment 352 engages with its corresponding first hole 232. This arrangement, on the one hand, provides more connection points between the first latching segment 351 and the first fixing part 31, effectively improving the connection strength between the second latching part 351 and the first fixing part 31; on the other hand, the multiple second latching segments 352 spaced apart circumferentially along the first fixing part 31 improves the uniformity of the connection strength distribution of the second latching part 351 and the first fixing part 31 in the circumferential direction, avoiding weak connection areas.

[0100] In at least one possible implementation, the first snap-fit ​​segment 351 is annular, and the second snap-fit ​​segment 352 may be provided with a first sealing portion 34.

[0101] Optionally, the first fixing part 31 further has a portion that contacts the surface of the second connecting part 25 opposite to the surface of the first connecting part 24. This portion that contacts the surface of the second connecting part 25 opposite to the surface of the first connecting part 24 may be provided with a first sealing part 34. This arrangement ensures that both sides of the first connecting part 24 in the axial direction have a first sealing part 34, thereby further improving the sealing effect. For example, as... Figure 3 As shown, the axis of the first connecting part 24 is referred to as the third axis Z3. In this embodiment, the third axis Z3 may or may not coincide with the first axis Z1; this embodiment does not limit this. In this embodiment, the direction of the third axis Z3 is the same as the direction of the first axis Z1.

[0102] In at least one possible implementation, the sealing structure 3 engages with the first cover 1. This arrangement facilitates the connection between the sealing structure 3 and the first cover 1, and also improves the flexibility of the sealing structure 3 and the first cover 1.

[0103] In one possible implementation, the sealing structure 3 and the first cover 1 can be assembled by plastic overmolding, or by interference assembly or mushroom head assembly. This embodiment does not limit this.

[0104] In at least one embodiment, the sealing structure 3 further includes a third engaging portion 36 disposed on the second fixing portion 32. Optionally, the second fixing portion 32 may be annular. The first cover 1 is provided with a second engaging portion 12 that engages with the third engaging portion 36. The second fixing portion 32 contacts the first cover 1, and the third engaging portion 36 engages with the second engaging portion 12, thereby achieving the engagement between the sealing structure 3 and the first cover 1. The second fixing portion 32 can contact the first cover 1 in a sealing manner, that is, the second fixing portion 32 abuts against the first cover 1, so that there is no gap between the second fixing portion 32 and the first cover 1.

[0105] In some alternative embodiments, such as Figure 7 or Figure 8 As shown, the second engaging part 12 can be a hole structure, groove structure, etc. provided on the first cover 1, and the third engaging part 36 can be a protrusion, ridge, etc. provided on the second fixing part 32. The protrusion or ridge is sealed in the hole structure or groove structure to achieve engaging and sealing.

[0106] Of course, it is understandable that the third snap-fit ​​part 36 can also be a hole structure or a groove structure, and the second snap-fit ​​part 12 can be a protrusion or a protrusion strip, as long as snap-fit ​​can be achieved. This embodiment does not limit this.

[0107] It is understandable that the fit between the third snap-fit ​​part 36 and the second snap-fit ​​part 12 can be an interference fit to ensure a seal between the third snap-fit ​​part 36 and the second snap-fit ​​part 12.

[0108] In at least one possible implementation, please refer to Figure 1 or Figure 2 The third connector and the second fixing part 32 have a concave-convex fit structure. Exemplarily, this embodiment provides a third connector and a second fixing part 32, but it is not limited thereto; the specific details can be flexibly adjusted according to requirements.

[0109] Optionally, such as Figure 7 and Figure 8 As shown, the first cover 1 includes a third connecting portion 17 and a fourth connecting portion 18 that are interconnected. The third connecting portion 17 and the fourth connecting portion 18 are arranged along the axial direction of the first cover 1. The third connecting portion 17 and the fourth connecting portion 18 are offset in a direction perpendicular to the axial direction of the first cover 1, and a second engaging portion 12 is provided on the third connecting portion 17 and / or the fourth connecting portion 18. In this embodiment, the third connecting portion 17 is closer to the axis of the first cover 1 (i.e., the third axis Z3) than the fourth connecting portion 18. The fourth connecting portion 18 is connected to the housing 40.

[0110] In one embodiment, such as Figure 7As shown, the second engaging portion 12 may include a first groove 121 and a second hole 122 disposed on the first cover 1. The first groove 121 may be formed by the mutual engagement of a third connecting portion 17 and a fourth connecting portion 18. The second hole 122 communicates with the first groove 121. In some optional embodiments, a portion of the second hole 122 is disposed in the third connecting portion 17, and another portion is disposed in the groove wall of the first groove 121.

[0111] In one possible implementation, the component that cooperates with the first cover 1 is, such as Figure 5 , Figure 6 or Figure 13 As shown, the third latching portion 36 includes a third latching segment 361 and a fourth latching segment 362 that are connected to each other. The fourth latching segment 362 is connected between the third latching segment 361 and the second fixing portion 32.

[0112] In some alternative embodiments, the third snap-fit ​​segment 361 and the second fixing portion 32 are arranged in the axial direction of the sealing structure 3. The third snap-fit ​​segment 361 and the second fixing portion 32 are offset in a direction perpendicular to the axial direction of the sealing structure 3, with the second fixing portion 32 being closer to the axis of the sealing structure 3 (i.e., the first axis Z1) than the third snap-fit ​​segment 361.

[0113] In one embodiment, the third latching segment 361 latches into the first groove 121, and the fourth latching segment 362 latches into the second hole 122. This configuration allows the first groove 121 to effectively restrict the position of the third latching segment 361, and the second hole 122 to restrict the position of the fourth latching segment 362. This results in the third latching portion 36 and the first cover 1 being interwoven and misaligned, forming a convex-concave fit structure, which further improves the connection strength and reliability between the third latching portion 36 and the first cover 1.

[0114] To further improve the connection strength between the third latching segment 361 and the second fixing part 32, in some optional embodiments, multiple fourth latching segments 362 are provided in a one-to-one correspondence with the first holes 232. These multiple fourth latching segments 362 are spaced apart circumferentially along the second fixing part 32, and each fourth latching segment 362 engages with its corresponding first hole 232. This arrangement, on the one hand, provides more connection points between the third latching segment 361 and the second fixing part 32, effectively improving the connection strength between the second latching part 35 and the second fixing part 32; on the other hand, the multiple fourth latching segments 362 spaced apart circumferentially along the second fixing part 32 also improves the uniformity of the connection strength distribution between the third latching part 361 and the second fixing part 32 circumferentially, avoiding weak connection areas.

[0115] In at least one possible implementation, the third snap-fit ​​segment 361 is annular, and the third connecting portion 17 and the fourth connecting portion 18 may also both be annular.

[0116] In at least one embodiment, please combine Figure 2 and Figure 7 As shown, the first cover 1 has a first surface 13 and a second surface 14 disposed opposite to each other in the thickness direction. The first surface 13 is the surface facing the box 40, that is, the first surface 13 can contact the box 40, and the second surface 14 is the surface away from the box 40.

[0117] In one implementation, such as Figure 2 or Figure 12 As shown, the second fixing part 32 has a second sealing part 37 protruding from the first surface 13. The second sealing part 37 is used to seal against the box body 40, thereby sealing the gap between the box body 40 and the first cover 1.

[0118] Optionally, the second sealing portion 37 may be annular and surround the outside of the connector body 20.

[0119] In at least one embodiment, the surface of the third latching portion 36 facing away from the first surface 13 is flush with the second surface 14. This arrangement ensures that the third latching portion 36 does not protrude from the second surface 14, preventing it from interfering with the assembly of the connector body 20 and its accessories, and also resulting in a flatter sealing connector cover 10.

[0120] For example, the opening of the first groove 121 is located on the second surface 14, and the surface of the third snap-fit ​​segment 361 disposed in the first groove 121 that faces away from the first surface 13 is flush with the second surface 14.

[0121] like Figure 2 As shown, the first cover 1 is provided with a connecting hole 15, which penetrates the first cover 1 along the thickness direction. A fastener 30 (such as a bolt, stud, etc.) passes through the connecting hole 15 and connects the first cover 1 and the box 40.

[0122] To improve the sealing performance at the connection hole 15, in some optional embodiments, such as Figure 5 and Figure 6 As shown, the sealing structure 3 also includes a third fixing part 38 and a fourth engaging part 39 disposed on the third fixing part 38. The third fixing part 38 is connected to the second fixing part 32. In this embodiment, the third fixing part 38 is annular, so that the third fixing part 38 can be arranged around the outer periphery of the fixing member 30. The periphery of the connecting hole 15 is provided with a third engaging part 16 that cooperates with the fourth engaging part 39. The third fixing part 38 contacts the first cover 1, and the fourth engaging part 39 engages with the third engaging part 16.

[0123] In this embodiment, by providing a fourth engaging portion 39 and a third engaging portion 16, and cooperating with the engaging portion 36 and the second engaging portion 12, the connection strength between the sealing structure 3 and the first cover 1 can be further improved, and the connection effect between the sealing structure 3 and the first cover 1 can be enhanced.

[0124] In some alternative embodiments, such as Figure 7 or Figure 8 As shown, the third engaging part 16 can be a hole structure, groove structure, etc. provided on the first cover 1, and the fourth engaging part 39 can be a protrusion, ridge, etc. provided on the third fixing part 38. The protrusion or ridge is sealed in the hole structure or groove structure to achieve engaging and sealing.

[0125] Of course, it is understandable that the fourth snap-fit ​​part 39 can also be a hole structure or a groove structure, and the third snap-fit ​​part 16 can be a protrusion or a protrusion strip, as long as snap-fit ​​can be achieved. This embodiment does not limit this.

[0126] It is understandable that the fourth snap-fit ​​part 39 and the third snap-fit ​​part 16 can be an interference fit to ensure a seal between the fourth snap-fit ​​part 39 and the third snap-fit ​​part 16.

[0127] Optionally, such as Figure 8 As shown, the second surface 14 of the first cover 1 is provided with a second groove 19, which is annular. The third fixing part 38 is engaged in the second groove 19 to achieve engagement with the first cover 1.

[0128] In some alternative embodiments, such as Figure 2 As shown, the third fixing part 38 has a third sealing part 3a that protrudes from the first surface 13. The third sealing part 3a is annular and surrounds the periphery of the fixing member 30 to seal the gap between the first cover 1 and the box 40, thereby improving the waterproof sealing effect at the connection between the first cover 1 and the box 40.

[0129] In this embodiment, to avoid the fourth snap-fit ​​portion 39 interfering with the assembly of the connector body 20 and the housing 40, the surface of the fourth snap-fit ​​portion 39 facing away from the first surface 13 is flush with the second surface 14, so that the sealing connection cover 10 can be more regular.

[0130] Optionally, such as Figures 5 to 7As shown, the third fixing part 38 is circumferentially disposed around the connecting hole 15. Multiple fourth engaging parts 39 are provided in a one-to-one correspondence with the third engaging parts 16. These multiple third engaging parts 16 are spaced apart circumferentially along the third fixing part 38, and each fourth engaging part 39 engages with its corresponding third engaging part 16. By providing multiple third engaging parts 16 and fourth engaging parts 39, the connection strength between the third fixing part 38 and the first cover 1 can be further improved, ensuring the secure connection between the third fixing part 38 and the first cover 1, thereby reducing the risk of separation between the sealing structure 3 and the first cover 1.

[0131] To further improve the connection strength between the second cover 2 and the connector body 20, in at least one embodiment, such as Figure 4 As shown, multiple first snap-fit ​​portions 22 are provided, and these multiple first snap-fit ​​portions 22 are spaced apart circumferentially along the second mounting hole 21. By providing multiple first snap-fit ​​portions 22, multiple positions of the connector body 20 in the circumferential direction can snap into the second cover 2, thereby improving the connection reliability between the connector body 20 and the sealing connection cover 10 and reducing the risk of abnormal separation between the connector body 20 and the sealing connection cover 10.

[0132] The sealing cap in the related technology only has a sealing function and does not have a vibration reduction and buffering function. When the connector device is used in a vehicle, it is more likely to fail due to the high intensity of vehicle vibration, which may cause the connection between the connector body 20 and the sealing cap to fail.

[0133] In one embodiment, the longitudinal section of the vibration damping part 33 is wavy, and there is a gap between the vibration damping part 33 and the first cover 1, and a gap between the vibration damping part 33 and the second cover 2, so as to provide space for the deformation of the vibration damping part 33. Here, the longitudinal section of the vibration damping part 33 refers to the section of the vibration damping part 33 cut by the plane containing the axis of the sealing structure 3 (i.e., the first axis Z1).

[0134] It is understandable that the longitudinal section of the vibration damping part 33 can be a regular curved shape, such as a rectangle, a smooth curve, or a zigzag line, or it can be other irregular shapes. This embodiment does not limit this.

[0135] In this embodiment, the outer circumferential side of the first fixing part 31 is flush with the outer circumferential side of the second cover 2 so as to provide a buffer space for the vibration damping part 33, so that the vibration damping part 33 can better absorb impact force and vibration force.

[0136] It should be noted that the sealing structure 3 is an integral structure, which can be understood as the first fixing part 31, the second fixing part 32, and the vibration damping part 33 being an integral structure.

[0137] This embodiment also provides a connector device, such as Figures 9 to 14As shown, the connector device includes the aforementioned sealing connection cover 10. The connector device also includes a connector body 20, the circumferential sidewall of which is provided with a locking structure 201. The connector body 20 passes through the second assembly hole 21, and the first locking part 22 engages with the locking structure 201 to achieve a detachable connection between the connector body 20 and the second cover 2.

[0138] The connector device provided in this embodiment has high sealing performance and connection reliability, and is easy to assemble and disassemble. The connector device also has high reliability and a long service life.

[0139] In at least one possible implementation, such as Figure 10 As shown, the first snap-fit ​​part 22 can be a boss provided on the second cover 2, and the snap-fit ​​structure 201 is a groove provided on the connector body 20. The boss can snap into the groove to achieve snap-fit.

[0140] In some alternative embodiments, such as Figure 4 As shown, the longitudinal section of the boss is triangular to facilitate the boss's insertion into and removal from the groove.

[0141] Optionally, such as Figure 9 As shown, the connector device also includes a fixing member 30, which is used to fix the sealing connection cover 10 to the housing 40. In this embodiment, multiple fixing members 30 may be provided to improve the connection strength.

[0142] The connector device in this embodiment can be a connector used in the electrical system of a vehicle, or a connector used in other electronic devices; this embodiment does not limit this.
