However, this connection method is not robust enough, and the snap-fit ​​structure cannot effectively limit the position of the terminal assemblies. Utility Model Content

[0003] Purpose of this application: This application provides a connector designed to overcome the technical problem of insufficiently secure connection between the terminal assembly and the housing; another purpose of this application is to provide a vehicle.

[0004] Technical solution: A connector according to an embodiment of this application includes:

[0005] A first housing has a first receiving cavity and a through hole communicating with the first receiving cavity. The first receiving cavity extends along a first direction, and the through hole extends along a second direction, wherein the first direction intersects the second direction.

[0006] The second housing is located inside and connected to the first housing. The second housing has a second housing cavity communicating with the first housing cavity for accommodating the terminal assembly. The second housing includes at least one snap-fit ​​portion for limiting the terminal assembly. The snap-fit ​​portion is spaced apart from the inner wall of the first housing cavity.

[0007] A limiting member is inserted through the through hole and connected to the first housing. The limiting member includes at least one abutting portion, at least a portion of which is located between the snap-fit ​​portion and the inner wall of the first receiving cavity and abuts against the snap-fit ​​portion.

Detailed Implementation

[0022] 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.

[0023] In the description of this application, it should be understood that 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 technical features indicated. Therefore, features defined as "first" or "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.

[0024] Vehicle connectors are electronic components that connect automotive electrical circuits. Composed of terminal assemblies, housings, and other structures, they transmit electrical energy to power various devices, transmit signals to ensure system coordination, and enable data transmission to support intelligent functions, playing a crucial role in vehicle operation. Currently, the terminal assemblies and housings of connectors are connected via a snap-fit ​​structure. However, this connection method is not robust enough. If the terminal assembly is subjected to external force, it will compress the snap-fit ​​structure, causing deformation and releasing its restraining effect on the terminal assembly, resulting in an insufficiently secure connection between the housing structure and the terminal assembly.

[0025] In view of this, embodiments of this application provide a connector to overcome at least one of the above-mentioned technical problems.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment of the application, the connector includes a first housing 10, a second housing 20, and a limiting member 40.

[0027] The first housing 10 has a first receiving cavity 11 and a through hole 12 communicating with the first receiving cavity 11. The first receiving cavity 11 extends along a first direction X, and the through hole 12 extends along a second direction Y, where the first direction X and the second direction Y intersect. The second housing 20 is located inside the first receiving cavity 11 and is connected to the first housing 10. The second housing 20 has a second receiving cavity 21 communicating with the first receiving cavity 11 for receiving a terminal assembly 30. The second housing 20 includes at least one snap-fit ​​portion 22 for limiting the terminal assembly 30. The snap-fit ​​portion 22 is spaced apart from the inner wall of the first receiving cavity 11 (the gap between the snap-fit ​​portion 22 and the inner wall of the first receiving cavity 11 is to facilitate the terminal assembly 30 to pass through the second receiving cavity 21 and snap-fit ​​with the snap-fit ​​portion 22). The limiting member 40 passes through the through hole 12 and is connected to the first housing 10. The limiting member 40 includes at least one abutting part 41. At least a portion of the abutting part 41 is located between the snap-fit ​​part 22 and the inner wall of the first receiving cavity 11 and abuts against the snap-fit ​​part 22.

[0028] It is understood that the second housing 20 can be disposed in the first receiving cavity 11 of the first housing 10 and connected to the first housing 10. The first housing 10 and the second housing 20 can be integrally formed to ensure the connection strength and prevent breakage at the connection point. The terminal assembly 30 passes through the second receiving cavity 21 of the second housing 20. The second housing 20 is engaged with the terminal assembly 30 through the snap-fit ​​portion 22, giving the terminal assembly 30 a certain degree of stability. However, if the terminal assembly 30 is subjected to external pulling force, it will compress the snap-fit ​​portion 22, causing one end of the snap-fit ​​portion 22 to deform away from the terminal assembly 30, thereby causing the snap-fit ​​portion 22 to lose its limiting function for the terminal assembly 30. By installing the limiting member 40, which is inserted into the interior of the first receiving cavity 11 through the through hole 12, the abutment portion 41 on the limiting member 40 can move between the snap-fit ​​portion 22 and the inner wall of the first receiving cavity 11, that is, move to the side of the snap-fit ​​portion 22 away from the terminal assembly 30 and abut against the snap-fit ​​portion 22. This arrangement allows the abutment portion 41 to support the latching portion 22, preventing the latching portion 22 from deforming away from the terminal assembly 30 under the action of other forces (due to the support of the abutment portion 41, the latching portion 22 is not easily deformed outwards). This ensures that during operation, the latching portion 22 is always engaged with the terminal assembly 30 and is always kept in place, thus guaranteeing the firmness of the connection between the second housing 20 and the terminal assembly 30.

[0029] Wherein, the first direction X can be the length direction of the first housing 10, and the second direction Y intersects the first direction X, including the case where the first direction X and the second direction Y are perpendicular to each other. When the first direction X and the second direction Y are perpendicular to each other, the second direction Y can be understood as the height direction of the first housing 10.

[0030] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In conjunction with the above embodiments, in some embodiments, the limiting member 40 includes a filling portion 42, which passes through the through hole 12 into the first receiving cavity 11 and is connected to the first housing 10. An abutment portion 41 is connected to one side of the filling portion 42. The connector includes a first sealing member 50, which is located inside the through hole 12 and connected to the inner wall of the through hole 12. The first sealing member 50 is disposed around the filling portion 42 to seal the filling portion 42 to the first housing 10.

[0031] It is understood that the filling part 42 on the limiting member 40 is connected to the abutting part 41, and the abutting part 41 can be moved by moving the filling part 42, such as being pulled out or embedded into the first receiving cavity 11. The filling part 42 passes through the through hole 12 and can fill the through hole 12, thereby improving the strength of the entire first housing 10 and avoiding excessive holes on it, which would make it easy to deform or even be damaged by external forces. At the same time, a first sealing member 50 (the first sealing member 50 can be made of sealing materials such as rubber and silicone) is provided on the inner wall of the through hole 12. The first sealing member 50 can be a ring structure, which is arranged circumferentially along the inner wall of the through hole 12. When the filling part 42 passes through the inside of the through hole 12, the first sealing member 50 is arranged around the outer periphery of the filling part 42 and is connected to the outer peripheral surface of the filling part 42. The first sealing element 50 can seal the connection between the filling part 42 and the inner wall of the through hole 12, improve the sealing effect at the connection between the filling part 42 and the first housing 10, and prevent water stains from seeping into the interior of the first receiving cavity 11 and the second receiving cavity 21 from the connection between the two, thus affecting the normal operation of the terminal assembly 30.

[0032] Please see Figure 7 In conjunction with the above embodiments, in some embodiments, the first seal 50 and the first housing 10 are integrally formed. It is understood that during the processing of the first housing 10 and the first seal 50, a double-shot molding process can be used to integrally form the first housing 10 and the first seal 50, ensuring a firm connection between them. This eliminates the need for separate post-processing of the first seal 50 and subsequent connection to the first housing 10, saving on the installation structure of the seal, reducing the overall connector assembly structure, and reducing the assembly steps of the entire connector.

[0033] Please see Figure 1 , Figure 5 and Figure 7 In conjunction with the above embodiments, in some embodiments, the limiting member 40 includes a main body 43 and a plurality of mounting parts 44.

[0034] The main body 43 is connected to the side of the filling part 42 opposite to the abutment part 41. Multiple mounting parts 44 are located on both sides of the first housing 10 in the third direction Z and are connected to the main body 43. Each mounting part 44 has a slot 441. The first housing 10 has protrusions 13 on both sides of the third direction Z, and these protrusions 13 engage with the corresponding slots 441. The third direction Z intersects with the first direction X and the second direction Y.

[0035] It is understandable that the main body 43 on the limiting member 40 is connected to the side of the filling part 42 away from the abutment part 41. The filling part 42 and the abutment part 41 can be moved by moving the main body 43. At the same time, the main body 43 covers the opening of the through hole 12, which can also play a certain sealing role, blocking water stains and dust from the outside, and preventing water stains and dust from entering the interior of the first receiving cavity 11 through the through hole 12. Multiple mounting portions 44 are respectively provided on both sides of the main body 43 along the third direction Z. The multiple mounting portions 44 are respectively connected to both sides of the main body 43. When the limiting member 40 is connected to the first housing 10, the multiple mounting portions 44 are respectively located on both sides of the first housing 10 along the third direction Z. Each mounting portion 44 is provided with a slot 441. At the same time, multiple protrusions 13 are respectively provided on both sides of the first housing 10 along the third direction Z. The protrusions 13 can engage with the corresponding slots 441, thereby achieving a stable connection between the limiting member 40 and the first housing 10, which can ensure the stability of the filling portion 42 and the abutment portion 41.

[0036] Please see Figure 6 , Figure 7 , Figure 9 and Figure 10 In conjunction with the above embodiments, in some embodiments, the second housing 20 includes a connecting portion 23 and a supporting portion 24.

[0037] The connecting portion 23 is located within the first receiving cavity 11 and is connected to the first housing 10. The supporting portion 24 is located within the first receiving cavity 11 and is connected to the connecting portion 23, serving to support the terminal assembly 30. The snap-fit ​​portion 22 is connected to the supporting portion 24 on the same side of the connecting portion 23. Both the supporting portion 24 and the snap-fit ​​portion 22 extend along the first direction X and together form the second receiving cavity 21.

[0038] Understandably, the connecting portion 23 of the second housing 20 has an annular structure and connects to the inner wall of the first receiving cavity 11. The supporting portion 24 is disposed on one side of the connecting portion 23 along the first direction X. The snap-fit ​​portion 22 is also connected to the connecting portion 23 and is disposed on the same side as the supporting portion 24. Together, they enclose the second receiving cavity 21 for the terminal assembly 30 to pass through. When the terminal assembly 30 passes through the second receiving cavity 21, the supporting portion 24 can support the terminal assembly 30, ensuring the stability of the terminal assembly 30 to a certain extent. At the same time, the snap-fit ​​portion 22 will also snap the terminal assembly 30, limiting its position and ensuring the firmness of the connection between the terminal assembly 30 and the second housing 20.

[0039] Please see Figure 6 , Figure 7 , Figure 9 and Figure 10In conjunction with the above embodiments, in some embodiments, the second housing 20 includes a plurality of support portions 24 and a plurality of snap-fit ​​portions 22, which are alternately spaced and surround to form a second receiving cavity 21.

[0040] It is understandable that the second housing 20 can have multiple support portions 24, spaced apart from each other, and multiple snap-fit ​​portions 22, also spaced apart from each other. These multiple support portions 24 and multiple snap-fit ​​portions 22 are alternately spaced and arranged around the terminal assembly 30. The multiple support portions 24 provide support to the terminal assembly 30 from multiple directions, improving the support effect. The multiple snap-fit ​​portions 22 allow for snap-fitting at different positions on the terminal assembly 30, increasing the number of snap-fit ​​structures and improving the limiting effect on the terminal assembly 30.

[0041] Please see Figure 1 , Figure 3 and Figure 4 In conjunction with the above embodiments, in some embodiments, the snap-fit ​​portion 22 includes a body 221 and a flange 222.

[0042] The body 221 is located within the first receiving cavity 11 and is connected to the connecting portion 23. A flange 222 is disposed on the side of the body 221 facing the terminal assembly 30 and is connected to the body 221. The flange 222 is used to limit the position of the terminal assembly 30.

[0043] It is understandable that the body 221 on the snap-fit ​​part 22 can extend along the first direction X. After extending to a suitable length, a flange 222 can be provided on the side of the body 221 facing the terminal assembly 30 (or a flange 222 can be provided on the inner side of the body 221). The flange 222 can be embedded into the recessed position on the terminal assembly 30 and cooperate with the corresponding recessed structure, so that the flange 222 and the recessed structure on the terminal assembly 30 snap-fit, thereby playing a certain limiting role on the terminal assembly 30.

[0044] Please see Figure 4 , Figure 9 , Figure 10 and Figure 11 In conjunction with the above embodiments, in some embodiments, one end of the first housing 10 has a first opening 14 communicating with the first receiving cavity 11; the connector includes a second seal 60, which is disposed in the first opening 14 and connected to the first housing 10. The second seal 60 is disposed around the terminal assembly 30 for sealingly connecting the terminal assembly 30 to the first housing 10.

[0045] It is understood that a first opening 14 is provided at one end of the first housing 10 along the first direction X. The first opening 14 communicates with the first receiving cavity 11. A second sealing element 60 (which can be a sealing material component such as rubber or silicone) is provided inside the first opening 14. The second sealing element 60 has a ring structure. When the terminal assembly 30 is installed, the terminal assembly 30 can pass through the interior of the second sealing element 60. The second sealing element 60 is arranged around the terminal assembly 30 and is tightly connected to the terminal assembly 30, so that the terminal assembly 30 can be sealed to the first housing 10 through the second sealing element 60, thereby improving the sealing effect and preventing external water stains or dust from entering the interior of the first receiving cavity 11 through the first opening 14.

[0046] The second seal 60 and the first housing 10 can be integrally formed by a double-shot molding process, so that the first housing 10 and the second seal 60 are firmly connected. There is no need to separately process the second seal 60 and then connect the second seal 60 to the first housing 10. This saves on the installation structure of the seal, reduces the assembly structure of the entire connector, and also reduces the assembly steps of the entire connector.

[0047] Please see Figure 4 , Figure 9 , Figure 10 and Figure 11 In conjunction with the above embodiments, in some embodiments, the other end of the first housing 10 has a second opening 15 communicating with the first receiving cavity 11; the connector includes a third seal 70, which is disposed in the second opening 15 and connected to the first housing 10, and the terminal assembly 30 passes through the third seal 70.

[0048] It is understood that a second opening 15 is provided at the other end of the first housing 10 along the first direction X. The second opening 15 communicates with the first receiving cavity 11 and is arranged opposite to the first opening 14. A third sealing element 70 (the third sealing element 70 can be a sealing material component such as rubber or silicone) is provided inside the second opening 15. The third sealing element 70 has a ring structure. When the terminal assembly 30 is installed, the terminal assembly 30 can pass through the interior of the third sealing element 70, or one end of the terminal assembly 30 can be embedded inside the third sealing element 70. The third sealing element 70 is arranged around a part of the terminal assembly 30 and is tightly connected to the terminal assembly 30, so that the terminal assembly 30 can be sealed to the first housing 10 through the third sealing element 70, thereby improving the sealing effect and preventing external water stains or dust from entering the interior of the first receiving cavity 11 through the second opening 15.

[0049] The third seal 70 and the first housing 10 can be integrally formed using a double-shot molding process, so that the two are firmly connected. There is no need to separately process the third seal 70 and then connect it to the first housing 10. This saves on the installation structure of the seal, reduces the assembly structure of the entire connector, and also reduces the assembly steps of the entire connector.
