[0002] In the related art, the sheath of a connector generally includes an integrally injection-molded or split middle island structure and side walls for surrounding the middle island structure. A sealing ring is usually sleeved on the middle island structure to achieve a sealed connection with the mating mechanism. However, the integrally injection-molded middle island structure may have a shrinkage phenomenon, and the split middle island structure has a mold joint line. When the sealing ring is sleeved on the middle island structure, gaps are formed between the sealing ring and the middle island structure, resulting in a reduction in sealing reliability. Summary of the Utility Model

[0003] An embodiment of this application provides a sheath structure, a connector, a controller, and a vehicle, which are based on making a first sealing surface and a second sealing surface fit together, thereby preventing a gap from being formed between the sealing ring and the connecting member to ensure the reliability of the seal.

[0011] Optionally, the seal further has a base surface facing away from the connecting member, and an outwardly convex sealing portion is formed on the base surface of the seal. The sealing portion is configured to deform under the action of the mating mechanism to seal the connection surface between the connecting member and the mating mechanism.

[0012] Optionally, the sealing portion extends in a first direction, and in a second direction, the number of the sealing portions is set to be at least two, wherein the first direction is perpendicular to the second direction.

[0013] Optionally, the sheath structure further includes side walls that surround the outside of the connecting member and are spaced apart from the connecting member. The sealing portion extends toward the side walls and is spaced apart from the side walls.

[0014] Optionally, a process hole is formed in the side wall, and the position of the process hole is adapted to the position of the limiting groove.

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0045] Referring to Figures 1 to 13 , the present application provides a sheath structure. The sheath structure includes a connector 1 and a seal 2. The connector 1 has a first sealing surface 11. The connector 1 forms an inwardly concave limiting groove 12 on the first sealing surface 11. The seal 2 is disposed around the connector 1. The seal 2 has a second sealing surface 21 facing the connector 1. The second sealing surface 21 is attached to the first sealing surface 11. The seal 2 forms an outwardly convex limiting portion 22 on the second sealing surface 21. The limiting portion 22 is clamped in the limiting groove 12, and the outer surface of the limiting portion 22 is attached to the groove wall surface of the limiting groove 12.

[0046] In some embodiments, by annularly arranging the seal 2 on the connecting member 1 and making the second sealing surface 21 of the seal 2 fit the first sealing surface 11 of the connecting member 1, a gap between the sealing ring and the connecting member 1 is prevented, ensuring the reliability of the seal. Based on constructing a limiting groove 12 on the connecting member 1 and a limiting portion 22 on the seal 2, the clamping between the limiting portion 22 and the limiting groove 12 is utilized to prevent relative movement between the seal 2 and the connecting member 1, thus avoiding the seal 2 falling off the connecting member 1. At the same time, making the outer surface of the limiting portion 22 fit the groove wall surface of the limiting groove 12 can, on the one hand, prevent a gap from forming at the connection between the limiting portion 22 and the limiting groove 12, and on the other hand, increase the sealing area, improve the sealing performance, and ensure the reliability of the seal.

[0047] Among them, the connecting member 1 is an island structure of the sheath structure of the connector, which is located at the middle position of the sheath structure. A side wall 3 is also arranged around the island structure of the sheath structure.

[0048] Such as Figure 5 and Figure 12 As shown, the first sealing surface 11 of the connecting member 1 is the outer peripheral surface of the connecting member 1. The limiting groove 12 is also formed on the outer peripheral surface of the connecting member 1. The groove wall surface of the limiting groove 12 includes the side wall surface and the groove bottom surface of the limiting groove 12.

[0049] Such as Figure 6 and Figure 13 As shown, the seal 2 is an elastic member and can be made of liquid silicone or other elastic materials. The seal 2 is a sealing ring. The second sealing surface 21 is the inner peripheral surface of the seal 2. The limiting portion 22 can be integrally formed on the inner peripheral surface of the seal 2 so that when the seal 2 is annularly arranged on the connecting member 1, the limiting portion 22 can be clamped in the limiting groove 12.

[0050] The shapes and sizes of the limiting portion 22 and the limiting groove 12 are exactly the same to ensure that after the limiting portion 22 is clamped in the limiting groove 12, the outer surface of the limiting portion 22 can completely fit the groove wall surface of the limiting groove 12.

[0051] In some embodiments, the seal 2 is injection molded on the connecting member 1.

[0052] It can be understood that the connecting member 1 is injection molded. The seal 2 is injection molded. Specifically, the seal 2 can also be injection molded. For example, the seal 2 can be formed on the first sealing surface 11 of the connecting member 1 by secondary injection molding with materials such as TPE (thermoplastic elastomer) and TPU (thermoplastic polyurethane). For example, the seal 2 can also be injection molded on the first sealing surface 11 of the connecting member 1 with materials such as silicone rubber and vulcanized after injection. Thus, the seal 2 and the connecting member 1 are closely fitted.

[0053] Based on the fact that the seal 2 is connected to the connecting piece 1 by means of secondary injection molding, it can be ensured that the second sealing surface 21 of the seal 2 can closely fit on the first sealing surface 11 of the connecting piece 1, so as to prevent the connection gap between the seal 2 and the connecting piece 1 from occurring due to the shrinkage deformation of the connecting piece 1 after injection molding, resulting in poor sealing effect.

[0054] By connecting the seal 2 to the connecting piece 1 by means of secondary injection molding or post-injection vulcanization, the shrinkage degree of the seal 2 in the first direction is basically the same, making its shrinkage uniform. Thus, the seal 2 can obtain a more ideal outer contour size, so that the sealing part 25 of the seal 2 is well compressed by the mating mechanism, ensuring the reliability of the seal at the connection between the seal 2 and the mating mechanism.

[0055] When the seal 2 is formed on the connecting piece 1 by secondary injection molding or post-injection vulcanization, the limiting part 22 clamped in the limiting groove 12 can be directly formed. After molding, the two can form a connection. Thus, the sealing ring can be made without designing an additional limiting structure, and the seal 2 can be prevented from falling off during the separation process of the connecting piece 1 and the mating mechanism after molding, ensuring that the seal 2 has sufficient holding force.

[0056] The following takes the secondary injection molding of the seal 2 on the connecting piece 1 as a specific example.

[0057] Before the secondary injection molding of the seal 2, a mold can be arranged around the outside of the connecting piece 1, and the mold is arranged at an interval from the connecting piece 1. The space between the mold and the connecting piece 1 is used for molding the seal 2. Among them, both sides of this space are limited by the connecting piece 1 and the mold respectively, the bottom of this space is limited by the elastic plate 32 of the side wall 3 or the bent part of the side wall 3, and the top of this space is limited by the top sealing plate of the mold. Thus, an injection cavity is formed. The injection molding machine injects molten plastic into this injection cavity. Under the action of the injection pressure, the molten plastic can closely adhere to the first sealing surface 11 of the connecting piece 1. Thus, after the plastic solidifies to form the seal 2, the second sealing surface 21 of the seal 2 can be made to closely adhere to the first sealing surface 11 of the connecting piece 1.

[0058] It can be understood that the seal 2 formed by secondary injection molding can fully adapt to the deformation of the first sealing surface 11 of the connecting piece 1. For example, when the first sealing surface 11 of the connecting piece 1 is an uneven surface, during the secondary injection molding process, the molten plastic can be filled into the concave area of the connecting piece 1 under the action of the injection pressure, so as to ensure that the second sealing surface 21 of the molded seal 2 closely adheres to the first sealing surface 11 of the connecting piece 1.

[0059] In some embodiments, as Figure 5 shown, along the first direction, the number of the limiting grooves 12 is set to at least two.

[0060] It is understandable that by providing at least two limiting grooves 12 and providing the same number of limiting portions 22 on the seal 2, the plurality of limiting portions 22 can be respectively clamped in the plurality of limiting grooves 12, further ensuring the reliable connection between the seal 2 and the connecting member 1 and preventing relative displacement between the two.

[0061] Wherein, the first direction is the direction on the circumferential side of the connecting member 1. The connecting member 1 is an island structure of a sheath structure. The connecting member 1 can be set in shapes such as oval, racetrack-shaped, circular, etc. For example, when the connecting member 1 is oval, the first direction is the circumferential direction of the oval, and the seal 2 is an oval sealing ring. When the connecting member 1 is racetrack-shaped, the first direction is the extending direction of the racetrack, and the seal 2 is a racetrack-shaped sealing ring.

[0062] For example, the connecting member 1 is racetrack-shaped. The number of the limiting grooves 12 is set to two. The two limiting grooves 12 are respectively located on two arc surfaces of the racetrack, and the two limiting grooves 12 can be symmetrically distributed. Correspondingly, the seal 2 also has limiting portions 22 provided on the inner sides of the two arc surfaces of the racetrack, and the two limiting portions 22 are symmetrically distributed.

[0063] For example, the connecting member 1 is circular. The number of the limiting grooves 12 is set to three. The three limiting grooves 12 are centrosymmetrically distributed. Correspondingly, the seal 2 also has three centrosymmetrically distributed limiting portions 22 provided on its inner side.

[0064] In some embodiments, at least two limiting grooves 12 arranged along the first direction can be arranged at intervals.

[0065] In some embodiments, at least two limiting grooves 12 arranged along the first direction can be arranged continuously.

[0066] It is understandable that the above setting manner of the limiting grooves 12 is applicable to the sheath structure with the side wall 3. Due to the protection and shielding of the side wall 3 for the connecting member 1, only by constructing process holes 31 on the side wall 3 can a plurality of limiting grooves 12 be formed.

[0067] In some embodiments, as Figure 12 shown, the limiting groove 12 extends along the first direction, the limiting groove 12 is set to at least two, and at least two limiting grooves 12 are arranged at intervals along the second direction, wherein the first direction is perpendicular to the second direction.

[0068] Wherein, when there is no side wall 3 provided outside the connecting member 1, the limiting groove 12 can extend along the first direction. And the limiting groove 12 can be set to at least two, and at least two limiting grooves 12 can be arranged at intervals along the second direction. Thus, it is convenient for the formation of the limiting groove 12, and at this time, there can be a larger connection area between the limiting groove 12 and the limiting portion 22, which can better ensure the stability of the connection between the seal 2 and the connecting member 1.

[0069] In some embodiments, at least two limiting grooves 12 arranged along the second direction may be spaced apart.

[0070] In some embodiments, such as Figure 6 and Figure 13 as shown, the limiting groove 12 includes at least one of a square groove, a semi-circular groove, a semi-elliptical groove, a V-shaped groove, and a U-shaped groove.

[0071] Based on the shape design of the limiting groove 12 and in cooperation with its snap connection with the limiting portion 22, the reliability of the connection between the seal 2 and the connecting member 1 can be ensured. For example, when the limiting groove 12 is set as a square groove, the limiting portion 22 is set as a cuboid structure. When the limiting groove 12 is set as a semi-circular groove, the limiting portion 22 is set as a hemispherical structure. When the limiting groove 12 is set as a semi-elliptical groove, the limiting portion 22 is set as a semi-ellipsoid structure. When the limiting groove 12 is set as a V-shaped groove, the limiting portion 22 is set as a triangular prism structure. When the limiting groove 12 is set as a U-shaped groove, the limiting portion 22 is set as a U-shaped columnar structure.

[0072] When at least two limiting grooves 12 are arranged along the first direction, the shapes of the at least two limiting grooves 12 may be the same or different. For example, the limiting grooves 12 are spaced apart into five. The five limiting grooves 12 are all semi-circular grooves. For example, the limiting grooves 12 are continuously arranged into four. The four limiting grooves 12 are all V-shaped grooves, and a groove structure approximately in a zigzag shape can be formed. For example, the limiting grooves 12 are continuously arranged into three. The three limiting grooves 12 are all U-shaped grooves, and a groove structure approximately in a wavy shape can be formed.

[0073] In some embodiments, the seal 2 further has a base surface 24 facing away from the connecting member 1. The seal 2 forms an outwardly convex sealing portion 25 on the base surface 24. The sealing portion 25 is configured to deform under the action of the mating mechanism to seal the connection surface between the connecting member 1 and the mating mechanism.

[0074] It can be understood that a mating mechanism will be plugged into the connector during actual use. When the connector is used as the female end, the mating mechanism can be a male head. Thus, the electrical connection between wire harnesses can be realized through the connector and the mating mechanism. Or the electrical connection between electrical components can be realized through the connector and the mating mechanism. After the mating mechanism is docked with the connecting member 1, the sealing portion 25 of the seal 2 abuts against the mating mechanism, and the sealing portion 25 can deform under the action of the mating mechanism, so that the seal 2 can achieve the effect of sealing the connection between the connecting member 1 and the mating mechanism.

[0075] Among them, the mating mechanism has at least an annular connecting portion. The annular connecting portion is sleeved on the outer side of the connecting member 1. At this time, the base surface 24 of the seal 2 abuts against the outer peripheral surface of the annular connecting portion, and the sealing portion 25 is squeezed and deformed by the annular connecting portion, so that the outer contour surface of the sealing portion 25 closely adheres to the inner surface of the annular connecting portion. Thus, a sealed connection between the annular connecting portion and the connecting member 1 is achieved.

[0076] The seal 2 can be made of liquid silicone or other elastic materials. The seal 2 is a sealing ring. The base surface 24 is the outer peripheral surface of the seal 2.

[0077] The sealing portion 25 is integrally formed on the outer peripheral surface of the seal 2. For example, when the seal 2 is secondarily injection-molded outside the connecting member 1, a groove is formed on the secondary injection mold, and after the liquid silicone flows into the groove and solidifies, the sealing portion 25 can be formed. And since the seal 2 is an elastomer, the mold can be normally detached from the sealing portion 25.

[0078] In some embodiments, the sealing portion 25 extends in a first direction. In a second direction, the number of the sealing portions 25 is set to at least two. Among them, the first direction is perpendicular to the second direction.

[0079] It can be understood that based on the first direction being the direction on the circumferential side of the connecting member 1, making the sealing portion 25 extend in the first direction can ensure the reliability of the seal at each position of the connecting member 1 and the mating mechanism in the first direction. Making the sealing portion 25 arranged in two or more in the second direction enables there to be multiple seal strengthening points between the connecting member 1 and the mating mechanism, further ensuring the reliability of their seal.

[0080] Among them, the second direction can be the height direction of the connecting member 1.

[0081] In some embodiments, at least two sealing portions 25 are connected and arranged.

[0082] In some embodiments, at least two sealing portions 25 are spaced apart and arranged.

[0083] In some embodiments, the cross-section of the sealing portion 25 can be set to a parabolic shape, a semi-circular shape, a semi-elliptical shape, a V shape or a U shape.

[0084] When the sealing portion 25 is arranged in at least two in the second direction, the sizes and shapes of at least two sealing portions 25 can be the same or different. For example, the sealing portion 25 is spaced apart and arranged in two. The cross-sections of the two sealing portions 25 are a V shape and a U shape respectively. For example, the sealing portion 25 is continuously arranged in four. The cross-sections of the four sealing portions 25 are all V shapes, then a sealing structure roughly in a zigzag shape can be formed. For example, the sealing portion 25 is continuously arranged in three. The cross-sections of the three sealing portions 25 are all U shapes, then a sealing structure roughly in a wavy shape can be formed.

[0085] In some embodiments, such as Figure 2 shown, the sheath structure further includes a side wall 3. The side wall 3 surrounds the outside of the connecting member 1 and is spaced apart from the connecting member 1. Among them, the sealing portion 25 extends in the direction of the side wall 3 and is spaced apart from the side wall 3.

[0086] It can be understood that the side wall 3 surrounds the connecting member 1. After the connecting member 1 is docked with the mating mechanism, the side wall 3 can socket the annular connecting portion of the mating mechanism inside to achieve a protective effect.

[0087] The sealing portion 25 extends from the seal 2 to the side wall 3 and is spaced apart from the side wall 3. Thus, an installation area for the annular connecting portion of the mating mechanism is formed between the sealing portion 25 and the side wall 3, realizing the assembly between the mating mechanism and the sheath structure.

[0088] In some embodiments, a process hole 31 is formed on the side wall 3. The position of the process hole 31 is adapted to the position of the limiting groove 12.

[0089] Based on making the position of the process hole 31 adapted to the position of the limiting groove 12, during the manufacturing and forming process of the sheath structure, the limiting groove 12 can be processed through the process hole 31.

[0090] The position of the process hole 31 being adapted to the position of the limiting groove 12 can be understood as: the process hole 31 is aligned with the limiting groove 12. Or, along the direction from the side wall 3 to the connecting member 1, the projection of the process hole 31 coincides with the projection of the limiting groove 12.

[0091] The shape of the process hole 31 can be the same as the shape of the notch of the limiting groove 12. For example, when the limiting groove 12 is a square groove, the process hole 31 is set as a square hole. For example, when the limiting groove 12 is a semi-circular groove, if the notch shape of the limiting groove 12 is semi-circular, the process hole 31 can be set as a semi-circular hole; if the notch shape of the limiting groove 12 is square, the process hole 31 is set as a square hole. For example, when the limiting groove 12 is a semi-elliptical groove, if the notch shape of the limiting groove 12 is semi-elliptical, the process hole 31 can be set as a semi-elliptical hole; if the notch shape of the limiting groove 12 is square, the process hole 31 is set as a square hole.

[0092] Among them, based on the number of the limiting grooves 12 being set to at least two, the number of the process holes 31 is also set to at least two. Each limiting groove 12 corresponds to a process hole 31 so that each limiting groove 12 can be processed and formed through a process hole 31.

[0093] When multiple limiting grooves 12 are spaced apart, the multiple process holes 31 are also spaced apart.

[0094] The present application also provides a connector. The connector includes a terminal 4 and a sheath structure as in the foregoing embodiments. The connector has all the beneficial effects of the above-mentioned sheath structure, which will not be elaborated herein again.

[0095] As Figure 3 shown, an installation channel 14 is formed on the connector 1. The installation channel 14 has an assembly port 141 and a mating socket 142 located on the outer surface of the connector 1. The assembly port 141 is used for installing the terminal 4, and the mating socket 142 is used for connecting to a mating mechanism. The terminal 4 can be inserted into the installation channel 14 from the assembly port 141, and the elastic reed 44 for electrically connecting the terminal 4 to the mating mechanism extends to a position close to the mating socket 142.

[0096] Among them, the installation channel 14 can penetrate the connector 1 along the length direction of the connector 1. At least two installation channels 14 can be arranged at intervals along the width direction of the connector 1. For example, three installation channels 14 are provided, and the three installation channels 14 are arranged in parallel along the width direction of the connector 1.

[0097] As Figure 3 shown, a retaining ledge 143 is formed in the installation channel 14. An elastic snap ring 43 is configured on the outer surface of the terminal 4. Along the direction from the socket 142 to the assembly port 141, the elastic snap ring 43 inclines towards the channel wall surface of the installation channel 14. Thus, after the terminal 4 is installed in the installation channel 14, the elastic snap ring 43 can be hooked on the retaining ledge 143, thereby realizing the primary locking of the terminal 4.

[0098] Please continue to refer to Figure 3 , the side wall 3 has an elastic plate 32 extending away from the connector 1. One end of the elastic plate 32 away from the connector 1 is connected with a cantilever plate 33. The cantilever plate 33 has the same extending direction as the connector 1, and the length of the cantilever plate 33 is less than the length of the connector 1. On the side close to the elastic plate 32, the cantilever plate 33 is connected with a stop portion 34, and the stop portion 34 is connected with an unlocking portion 35 spaced from the elastic plate 32. An accidental unlocking protection portion 36 spaced from the unlocking portion 35 is also formed on the side wall 3. The accidental unlocking protection portion 36 is spaced from the stop portion 34. The accidental unlocking protection portion 36 can abut against the stop portion 34 so that the unlocking portion 35 cannot drive the stop portion 34 to rotate towards the accidental unlocking protection portion 36.

[0099] When the mating mechanism needs to be disassembled, the unlocking portion 35 can be pressed to drive the stop portion 34 to rotate away from the accidental unlocking protection portion 36. The rotation center can be the elastic plate 32, or the rotation center is the connection portion of the elastic plate 32 and the connector 1. At this time, the stop portion 34 can drive the cantilever plate 33 to rotate away from the connector 1, and the cantilever plate 33 gradually moves away from the connector 1, which can facilitate the disassembly of the mating mechanism.

[0100] Among them, a first through hole 37 can also be formed on the side wall 3, and the first through hole 37 can be used to form a second through hole 331 on the cantilever plate 33. The second through hole 331 can accommodate the hanging platform of the mating mechanism, and the second through hole 331 cooperates with the hanging platform of the mating mechanism to realize the self-locking of the sheath structure and the mating mechanism.

[0101] At one end far from the elastic plate 32, the cantilever plate 33 forms an inclined surface 332. Along the direction from the assembly port 141 to the socket 142, the inclined surface 332 inclines away from the connecting member 1. Thus, the inclined surface 332 can play a guiding effect to prevent the mating mechanism from being stuck by the cantilever plate 33 during assembly, and play an installation guiding effect.

[0102] Among them, along the direction from the assembly port 141 to the socket 142, the terminal 4 includes a first wire clamp 41, a second wire clamp 42, an elastic snap spring 43, and an elastic reed 44 that are connected in sequence. The first wire clamp 41 is used for crimping the outer sheath of the wire. The second wire clamp 42 is used for crimping the core of the wire. Among them, a plurality of first grooves 45 are formed on the inner surface of the second wire clamp 42 to enhance the holding force of the second wire clamp 42 for crimping the core. The elastic snap spring 43 is used for hanging on the anti-retreat hanging platform 143 of the installation channel 14. The elastic reed 44 is used for electrically connecting the mating mechanism.

[0103] Please refer to Figure 4 , a boss 46 is also formed on the outer surface of the terminal 4. A thrust portion 144 is also formed in the installation channel 14. The boss 46 is used for abutting against the thrust portion 144, thereby limiting the maximum assembly distance of the terminal 4 to prevent the terminal 4 from being inserted excessively.

[0104] In some embodiments, a locking connection portion is formed on the connecting member 1. The locking connection portion is used for cooperating with the locking mechanism 5 to realize the secondary locking of the terminal 4.

[0105] As Figure 2 and Figure 13 shown, the locking connection portion includes a pre-positioning groove 15 and a locking groove 16 formed on the surface of the connecting member 1. The locking mechanism 5 has a protruding portion 51. When the protruding portion 51 is snapped into the pre-positioning groove 15, the locking mechanism 5 completes pre-positioning. When the protruding portion 51 is snapped into the locking groove 16, the locking mechanism 5 can perform secondary locking on the terminal 4.

[0106] To install the locking mechanism 5, a third through-hole 38 is formed on the side wall 3. The locking mechanism 5 can be installed on the locking connection part through the third through-hole 38. Among them, a relief groove 17 can be provided on the connecting member 1, and a convex portion 171 extending toward the center of the groove is formed at the notch of the relief groove 17 of the connecting member 1. A sliding groove 52 is also formed on the locking mechanism 5, and the sliding groove 52 is used for slidably connecting the convex portion 171. Among them, the aforementioned protruding portion 51 can be provided on the groove wall surface of the sliding groove 52. The relief groove 17 can be used to accommodate a part of the structure of the locking mechanism 5 to prevent the engagement failure between the protruding portion 51 and the pre-positioning groove 15 or the locking groove 16.

[0107] As Figure 13 shown, a plurality of convex ribs 53 are also formed on the locking mechanism 5 at intervals. A through-set groove 54 can be formed between the plurality of convex ribs 53. When the protruding portion 51 is engaged with the pre-positioning groove 15, the locking mechanism 5 completes pre-positioning. At this time, the terminal 4 can be installed into the installation channel 14 and pass through from the position of the through-set groove 54. When the protruding portion 51 is engaged with the locking groove 16, the convex rib 53 can form a hanging connection with the constricted portion of the terminal 4, thereby realizing the locking of the terminal 4.

[0108] Among them, a second groove 55 can also be provided at the position of the locking mechanism 5 close to the protruding portion 51, so as to improve the ability of the protruding portion 51 to expand outward. It can be understood that the second groove 55 can reduce the thickness of the locking mechanism 5 at the position close to the protruding portion 51, making it easier for the protruding portion 51 to expand outward and then slide into the pre-positioning groove 15 or the locking groove 16.
