[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, the range of included angles from 80° to 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles from 10° is considered parallel.

[0031] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a connector, including a housing 100, a plurality of terminals 200, and a seal 300. The housing 100 has a receiving cavity 110, which extends through the housing 100 along the axial direction X. The plurality of terminals 200 are at least partially disposed in the receiving cavity 110. The seal 300 is embedded in the receiving cavity 110 and is sealed to the housing 100. The seal 300 has a plurality of through holes 310 and a buffer groove 320. The through holes 310 extend through the seal 300 along the axial direction X. Each terminal 200 passes through one through hole 310 and is sealed to the seal 300. The buffer groove 320 extends through one side of the seal 300 along the axial direction X. The plurality of through holes 310 are spaced apart around the buffer groove 320.

[0032] In this embodiment of the application, by providing a buffer groove 320 between multiple through holes 310 of the seal 300, when multiple terminals 200 are inserted into the through holes 310, the buffer groove 320 provides deformation space for the seal 300 to be deformed by the compression of the terminal 200 when it is inserted, effectively protecting the seal from being scratched, and facilitating the assembly of the terminal 200 and the seal 300.

[0033] Specifically, in this embodiment, the housing 100 is used to accommodate multiple terminals 200 and a seal 300. The seal 300 is typically a rubber injection molded part, used to fix the terminals 200 and the housing 100, and also serves a sealing function to ensure the sealing performance of the wiring harness connection at the tail of the terminal 200, thereby improving the safety of the connector when it is powered on. The number of through holes 310 in the seal 300 corresponds one-to-one with the number of terminals 200. Typically, the diameter of the through hole 310 is slightly smaller than the outer diameter of the terminal 200, so that the seal 300 tightly wraps around the terminal 200 when it is inserted into the through hole 310.

[0034] It should be noted that in this embodiment of the application, the buffer groove 320 is set between multiple through holes 310. At this time, no matter which through hole 310 the terminal 200 is inserted, the corresponding buffer groove 320 can provide buffer space for the material around the through hole 310, so as to facilitate the insertion of the terminal 200 and avoid interference with adjacent terminals 200.

[0035] Please refer to the following: Figure 3 , Figure 4 and Figure 5 In some embodiments, the seal 300 includes a first body 330 and a plurality of sealing rings 340. The first body 330 has a plurality of through holes 310 and a buffer groove 320. At least two sealing rings 340 are provided in each through hole 310. The at least two sealing rings 340 are spaced apart in the through hole 310 along the axial direction X and are both connected to the first body 330. The sealing rings 340 can be tilted and deformed in the through hole 310 along the axial direction X. The sealing rings 340 are sealed and fitted on the outer periphery of the terminal 200.

[0036] In this embodiment, by providing multiple sealing rings 340 on the wall of the through hole 310, the dimension of the sealing ring 340 along the axial direction X is smaller than the dimension of the wall of the through hole 310 along the axial direction X. This results in a stronger deformation capacity for the sealing ring 340, allowing it to deform in the insertion direction of the terminal 200 as it is inserted, and to more tightly wrap and adhere to the outer wall of the terminal 200, achieving a better seal. Furthermore, the spacing between adjacent sealing rings 340 provides space for deformation within the through hole 310.

[0037] Please refer to the following: Figure 7 , Figure 8 and Figure 12In some embodiments, the housing 100 includes a second body 120 and a first positioning part 130. The second body 120 has a receiving cavity 110, and the first positioning part 130 is disposed in the receiving cavity 110 and connected to the second body 120. The first positioning part 130 divides the receiving cavity 110 into a first chamber 111 and a second chamber 112 along the axial direction X. A sealing member 300 is embedded in the first chamber 111, and a buffer groove 320 is disposed on the side of the first body 330 away from the first positioning part 130. The first positioning part 130 has a plurality of first positioning holes 131, which penetrate the first positioning part 130 along the axial direction X and communicate with the first chamber 111 and the second chamber 112 respectively. A plurality of through holes 310 are provided one-to-one with the plurality of first positioning holes 131, and each through hole 310 is coaxial with and communicates with a first positioning hole 131. Each terminal 200 passes through a first positioning hole 131.

[0038] In this embodiment, the first positioning part 130 is disposed within the receiving cavity 110 of the second body 120. The first positioning hole 131 cooperates with the through hole 310 of the sealing member 300 to guide, position, and fix multiple terminals 200, and divides the receiving cavity 110 into a first chamber 111 and a second chamber 112. The first chamber 111 is used to accommodate the sealing member 300 and the wire harness, and the second chamber 112 is used to mate with a mating connector. This structure achieves effective sealing, fixing, and protection between the terminals 200 and the housing 100.

[0039] It should be noted that the buffer groove 320 is located on the side of the first body 330 away from the first positioning part 130. At this time, the buffer groove 320 is located on the side where the terminal 200 is assembled and inserted, which makes it easier for the hole wall of the through hole 310 to deform towards the buffer groove 320 so that the terminal 200 can be smoothly inserted into the through hole 310.

[0040] Please refer to the following: Figure 7 , Figure 8 and Figure 12In some embodiments, the housing 100 further includes a second positioning part 140, a plurality of first limiting parts 150, and a plurality of second limiting parts 160. The second positioning part 140 is disposed in the second chamber 112 and connected to the first positioning part 130. The second positioning part 140 has a plurality of second positioning holes 141, which penetrate the second positioning part 140 along the axial direction X and are connected to the plurality of first positioning holes 131 in a one-to-one correspondence. Each first limiting part 150 is disposed in one of the second positioning holes 141 and is connected to the first limiting part 160. The first positioning part 150 is connected to the second positioning part 130; each second limiting part 160 is disposed on one side of a second positioning hole 141 and is disposed opposite to the first limiting part 150, and the second limiting part 160 is connected to the first positioning part 130; a portion of the second limiting part 160 extends into the second positioning hole 141 and can be deformed in the radial direction of the housing 100 toward or away from the second positioning hole 141; wherein, a portion of the terminal 200 passes through the second positioning hole 141 and is connected to the first limiting part 150 and the second limiting part 160 respectively.

[0041] In this embodiment, the second positioning part 140 is provided with a second positioning hole 141 for further guiding and positioning the terminal 200. At the same time, a first limiting part 150 and a second limiting part 160 are provided to achieve effective positioning and limiting after the terminal 200 is connected to the housing 100, preventing the terminal 200 from being unable to be used normally due to the transition of the assembly position after being connected to the housing 100, and preventing the subsequent failure of the connection between the terminal 200 and the housing 100.

[0042] In this embodiment, the second positioning part 140 may also be provided with a plurality of first clearance grooves. The first clearance grooves penetrate the side of the second positioning part 140 away from the first positioning part 130 along the axial direction X, and penetrate the outer side wall of the second positioning part 140 along the radial direction. Each first clearance groove communicates with a second positioning hole 141, and each second limiting part 160 is disposed in the first clearance groove and connected to the first positioning part 130. In this case, the provision of the first clearance grooves can provide deformation space for the second limiting part 160, avoiding interference from the second positioning part 140 to the deformation of the second limiting part 160.

[0043] It should be noted that the first limiting part 150 protrudes from the inner side wall of the second positioning hole 141, and a portion of the second limiting part 160 is used to form the second positioning hole 141, and a portion of the second limiting part 160 protrudes from the second positioning hole 141, so that the terminal 200 can be connected to the first limiting part 150 and the second limiting part 160 and mutually limit each other.

[0044] like Figure 8As shown, in some embodiments, a first positioning groove 210 is provided on the outer wall of the terminal 200, and portions of the first limiting part 150 and the second limiting part 160 are disposed in the first positioning groove 210 and mutually limit each other with the groove wall of the first positioning groove 210 along the axial direction X.

[0045] In this embodiment of the application, by providing a first positioning groove 210 on the outer side wall of the terminal 200, the first limiting part 150 and the second limiting part 160 are partially embedded in the first positioning groove 210, thereby achieving mutual limiting between the terminal 200 and the housing 100 along the axial direction X, effectively preventing the terminal 200 from being misaligned during installation and from becoming loose.

[0046] Please refer to the following: Figure 7 , Figure 8 and Figure 12 In some embodiments, the housing 100 further includes a third positioning part 170 and a plurality of third limiting parts 180. The third positioning part 170 is disposed in the second chamber 112 and connected to the side of the second positioning part 140 away from the first positioning part 130. The third positioning part 170 has a plurality of third positioning holes 171, which penetrate the third positioning part 170 along the axial direction X and are connected to the plurality of second positioning holes 141 in a one-to-one correspondence. A portion of the terminal 200 passes through the third positioning hole 171. At least one third limiting part 180 is disposed in a third positioning hole 171 and connected to the third positioning part 170. The terminal 200 has a second positioning groove 220, which is disposed in the side of the first positioning groove 210 away from the first positioning part 130. The third limiting part 180 is disposed in the second positioning groove 220 and connected to the terminal 200.

[0047] In this embodiment, the third positioning part 170 is provided to provide the third positioning hole 171 to provide further guidance and positioning for the terminal 200. At the same time, the third limiting part 180 cooperates with the second positioning groove 220 of the terminal 200 to achieve further positioning and limiting of the terminal 200 by the housing 100, thereby improving the stability of the housing 100 and the terminal 200 after assembly.

[0048] It should be noted that one or more third limiting parts 180 may be provided in each third positioning groove 121, preferably multiple third limiting parts 180 to provide multiple limiting points to limit the terminal 200. The third limiting parts 180 are staggered with the first limiting parts 150 and the second limiting parts 160, so that the positioning and limiting of the terminal 200 can be more uniform in the circumference, improving the positioning and limiting effect and uniformity.

[0049] Please refer to the following: Figure 8 and Figure 10In some embodiments, the connector further includes a first connector 400, which includes a limiting ring 410 and a plurality of fourth limiting portions 420. The limiting ring 410 is spaced between the second body 120 and the third positioning portion 170 and is detachably connected to the second body 120 and the third positioning portion 170, respectively. The plurality of fourth limiting portions 420 are connected to the side of the limiting ring 410 facing the first positioning portion 130. Each fourth limiting portion 420 is disposed between the second body 120 and a second limiting portion 160 and is connected to the second body 120 and the second limiting portion 160, respectively.

[0050] In this embodiment, the first connector 400 is used to further lock and reinforce the connection between the terminal 200 and the housing 100, improving the stability of the connection between the terminal 200 and the housing 100. The limiting ring 410 is embedded between the third positioning part 170 and the second body 120, enabling initial fixation of the first connector 400 and the housing 100, facilitating the extension of the fourth limiting part 420 between the second limiting part 160 and the second body 120. The fourth limiting part 420 is inserted between the second body 120 and the second limiting part 160, abutting against both. The fourth limiting part 420 presses the second limiting part 160 into the second positioning hole 141, thereby more firmly fixing the second limiting part 160 within the first positioning groove 210, achieving a tighter connection between the housing 100 and the terminal 200, and effectively preventing the terminal 200 from loosening.

[0051] Please refer to the following: Figure 9 and Figure 10 In some embodiments, the first connector 400 further includes a plurality of fifth limiting portions 430, which are connected to the side of the limiting ring 410 facing the first positioning portion 130 and are spaced apart from the fourth limiting portion 420; the fifth limiting portion 430 has a fourth positioning groove 431; the second body 120 has a third positioning groove 121, which communicates with the second chamber 112, and the fifth limiting portion 430 passes through the third positioning groove 121; the second body 120 includes a sixth limiting portion 122, which is disposed in the third positioning groove 121 and connected to the groove wall of the third positioning groove 121, and the sixth limiting portion 122 is disposed in the fourth positioning groove 431.

[0052] In this embodiment, the opening of the third positioning groove 121 faces the limiting ring 410. By setting the fifth limiting part 430 and the third positioning groove 121 to cooperate, a tighter connection between the first connector 400 and the housing 100 can be achieved, and rotation along the circumference of the housing 100 can be prevented. Specifically, by using the fourth positioning groove 431 of the fifth limiting part 430 and the sixth limiting part 122 in the third positioning groove 121 to engage with each other, the positioning and limiting of the first connector 400 and the housing 100 along the axial direction X can be achieved, improving the stability of the connection between the first connector 400 and the housing 100. This achieves the locking function of the first connector 400 connecting the terminal 200 and the housing 100, while ensuring a stable connection and preventing detachment between the first connector 400 and the housing 100.

[0053] like Figure 9 As shown, in some embodiments, the second body 120 also has a plurality of fifth positioning grooves 123, which are spaced apart around the outer periphery of the second positioning part 140; the first connector 400 also includes a plurality of spaced seventh limiting parts 440, which are connected to the side of the limiting ring 410 facing the first positioning part 130, and each seventh limiting part 440 passes through a fifth positioning groove 123.

[0054] In this embodiment, the opening of the fifth positioning groove 123 faces the limiting ring 410, and a plurality of seventh limiting parts 440 are respectively inserted into the fifth positioning groove 123 in a corresponding manner, which can realize further connection and fixation between the first connector 400 and the housing 100.

[0055] Please refer to the following: Figure 1 , Figure 2 , Figure 6 , Figure 9 and Figure 13 In some embodiments, the connector further includes a second connector 500 disposed on the side of the seal 300 away from the first positioning portion 130; the second connector 500 includes a third body 510 and a fourth positioning portion 520, the third body 510 having a plurality of fourth positioning holes 511, the fourth positioning holes 511 penetrating the third body 510 along the axial direction X; a portion of the third body 510 is disposed within the first chamber 111, and a portion of the terminal 200 is disposed within the fourth positioning holes 511; the fourth positioning portion 520 is connected to the third body 510 and forms a sixth positioning groove 530, a portion of the second body 120 being disposed within the sixth positioning groove 530.

[0056] In this embodiment, the second connector 500 is used to connect with the housing 100 and seal the first chamber 111, thus preventing the seal 300 from loosening from the first chamber 111. Furthermore, the third body 510 of the second connector 500 is inserted into the first chamber 111, and the fourth positioning part 520 surrounds the outside of the second body 120, achieving a snap-fit ​​connection with the second body 120, effectively ensuring the connection stability between the second body 120 and the second connector 500.

[0057] Please refer to the following: Figure 1 , Figure 11 and Figure 13 In some embodiments, the fourth positioning part 520 has a plurality of seventh positioning grooves 521 and an eighth positioning groove 522. The seventh positioning grooves 521 penetrate the fourth positioning part 520 along the axial direction X on the side near the second body 120, and the plurality of seventh positioning grooves 521 are arranged at intervals along the circumference of the fourth positioning part 520. The eighth positioning grooves 522 are arranged at intervals between two adjacent seventh positioning grooves 521 along the circumference of the fourth positioning part 520, and penetrate the fourth positioning part 520 radially along the second connector 500. The housing 100 includes a plurality of eighth limiting parts 190 and a ninth limiting part 191. The plurality of eighth limiting parts 190 are arranged at intervals along the circumference of the second body 120 and are all connected to the second body 120. Each eighth limiting part 190 is inserted into a seventh positioning groove 521. The ninth limiting part 191 is connected to the outer side wall of the second body 120 and is disposed in the eighth positioning groove 522.

[0058] In this embodiment, multiple seventh positioning grooves 521 are used to accommodate the eighth limiting part 190 so that the eighth limiting part 190 engages with the fourth positioning part 520, thereby preventing the second connecting member 500 from rotating with the housing 100 in the circumferential direction. The eighth positioning groove 522 is used to accommodate the ninth limiting part 191, thereby engaging the fourth positioning part 520 with the ninth limiting part 191, and achieving a limiting connection between the second connecting member 500 and the housing 100 in the axial direction X.

[0059] Among them, two adjacent seventh positioning grooves 521 separate the fourth positioning part 520 into an elastic latch 523. The elastic latch 523 can deform radially along the housing 100, thereby facilitating the connection and disassembly of the second connector 500 and the housing 100.

[0060] like Figure 6 As shown, in some embodiments, the second connector 500 further includes a fifth positioning part 540, which is connected to the side of the third body 510 facing the seal 300; the first body 330 has a ninth positioning groove 331, which is disposed on the side of the first body 330 away from the first positioning part 130, and the fifth positioning part 540 passes through the ninth positioning groove 331.

[0061] In this embodiment, a ninth positioning groove 331 is provided in the first body 330 of the sealing member 300, which cooperates with the fifth positioning part 540 of the second connector 500. The fifth positioning part 540 passes through the ninth positioning groove 331, and the first body 330 abuts against one side of the first positioning part 130, thereby effectively fixing the sealing member 300. At the same time, the ninth positioning groove 331 can also provide deformation space during the assembly of the terminal 200, which is beneficial for the assembly of the terminal 200 and prevents the sealing member 300 from being scratched.
