[0006] A fixing component is located inside and connected to the housing. The fixing component includes a support portion and multiple limiting portions. The support portion and the housing enclose multiple mounting cavities. The multiple mounting cavities are arranged at intervals along a third direction. Each mounting cavity extends along a first direction and communicates with the through hole. The first direction, the second direction, and the third direction intersect each other in pairs. Each mounting cavity is provided with a terminal assembly. Each mounting cavity is provided with at least one limiting portion connected to the support portion.

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] Vehicle connectors are electronic components that connect automotive electrical circuits. Composed of multiple terminal assemblies and a housing, 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 multiple terminal assemblies on the connector are connected to the housing via a snap-fit ​​structure. However, this connection method is not robust enough. If the terminal assemblies are subjected to external force, they will compress the corresponding snap-fit ​​structure, causing deformation and releasing its restraining effect on the terminal assemblies. This results in an insufficiently secure connection between the housing structure and the terminal assemblies.

[0023] In view of this, embodiments of this application provide a connector to overcome at least one of the above-mentioned technical problems.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment of the application, the connector includes a housing 10, a fixing component 20, and a blocking component 40.

[0025] The housing 10 has a through hole 11 extending along the second direction Y. The fixing component 20 is located inside the housing 10 and connected to the housing 10. The fixing component 20 includes a support portion 21 and a plurality of limiting portions 22. The support portion 21 and the housing 10 enclose a plurality of mounting cavities 12. The plurality of mounting cavities 12 are arranged at intervals along the third direction Z. Each mounting cavity 12 extends along the first direction X and communicates with the through hole 11. The first direction X, the second direction Y and the third direction Z intersect each other in pairs. Each mounting cavity 12 is provided with a terminal assembly 30. Each mounting cavity 12 is provided with at least one limiting portion 22 connected to the support portion 21. The limiting portion 22 is engaged with the corresponding terminal assembly 30. The blocking assembly 40 passes through the through hole 11 into each mounting cavity 12 and is connected to the housing 10. The blocking assembly 40 includes a plurality of abutment portions 41, at least a portion of each abutment portion 41 being located on the side of a limiting portion 22 away from the corresponding terminal assembly 30 and abutting against the limiting portion 22.

[0026] It is understood that the first direction X can be the length direction of the outer casing 10, the second direction Y can be the height direction of the outer casing 10, and the third direction Z can be the width direction of the outer casing 10. Therefore, these three directions intersect each other, and preferably, they can be perpendicular to each other. The through hole 11 extends along the second direction Y and communicates with the interior of the outer casing 10. A fixing component 20 is provided inside the outer casing 10. The fixing component 20 includes a support part 21 and a plurality of limiting parts 22. The support part 21 is connected to the interior of the outer casing 10 and forms a plurality of mounting cavities 12 between it and the interior of the outer casing 10. The plurality of mounting cavities 12 are spaced apart along the third direction Z. Each mounting cavity 12 can accommodate a terminal assembly 30, so that a plurality of terminal assemblies 30 can be installed inside the outer casing 10. A limiting part 22 is provided inside each mounting cavity 12. The limiting part 22 engages with the terminal assembly 30 to limit the terminal assembly 30. The limiting part 22 can be connected to the support part 21, thereby effectively fixing the limiting part 22. The number of limiting parts 22 in each mounting cavity 12 can be one or more. Setting multiple limiting parts 22 can improve the limiting effect on the corresponding terminal assembly 30.

[0027] A blocking component 40 is also provided on the connector. The blocking component 40 passes through the through hole 11 to the interior of each mounting cavity 12. That is, each mounting cavity 12 has a part of the blocking component 40 inside. This part can be an abutment part 41. At least a part of the abutment part 41 is provided on the side of a limiting part 22 away from the corresponding terminal assembly 30. The abutment part 41 and the terminal assembly 30 are respectively provided on opposite sides of the limiting part 22. When the terminal assembly 30 is pulled by an external force and tends to move in the first direction X, it will push and squeeze the limiting part 22. The abutment part 41 can support the limiting part 22 and provide it with a reverse force to prevent it from deforming. This ensures that the limiting part 22 always limits the corresponding terminal assembly 30, improves the limiting effect, and thus improves the firmness of the connection between the terminal assembly 30 and the internal structure of the housing 10.

[0028] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9 In conjunction with the above embodiments, in some embodiments, the blocking assembly 40 includes a connecting portion 42. The connecting portion 42 passes through the through hole 11 and is connected to the housing 10, and a plurality of abutting portions 41 are connected to one side of the connecting portion 42. The connector includes a first sealing member 50, which is located within the through hole 11 and connected to the inner wall of the through hole 11. The first sealing member 50 is disposed around the connecting portion 42, and the connecting portion 42 is sealed to the housing 10 through the first sealing member 50.

[0029] It is understandable that a connecting part 42 is provided on the blocking component 40. The connecting part 42 can pass through the through hole 11 and fill the through hole 11 (since the through hole 11 needs to accommodate multiple limiting parts 22 embedded in the corresponding mounting cavity 12, the opening of the through hole 11 is generally large, which reduces the overall strength of the outer shell 10 and makes it prone to deformation or even damage under external force). The connecting part 42 supports the inner wall of the through hole 11, thereby improving the overall strength of the outer shell 10 and preventing it from easily deforming. Multiple abutting parts 41 can be connected to one side of the connecting part 42. When the connecting part 42 passes through the interior of the through hole 11, it can drive the multiple abutting parts 41 to be embedded into the interior of the corresponding mounting cavity 12 and abut against the corresponding limiting part 22. A first sealing element 50 (which may be made of sealing materials such as rubber or silicone) can be connected to the inner wall of the through hole 11. The first sealing element 50 has an annular structure and is arranged circumferentially along the inner wall of the through hole 11. It is also arranged around the connecting part 42 and fits tightly with the connecting part 42. This can improve the sealing performance of the connection between the connecting part 42 and the outer shell 10 and prevent external water stains, dust and other foreign objects from entering the mounting cavity 12 through the through hole 11.

[0030] The first seal 50 is integrally formed with the outer shell 10. During the processing of the outer shell 10 and the first seal 50, a double-shot molding process can be used to integrally form the outer shell 10 and the first seal 50, so that the two are firmly connected. It is not necessary to process the first seal 50 separately later and then connect the first seal 50 to the outer shell 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.

[0031] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9 In conjunction with the above embodiments, in some embodiments, a sealing groove 421 is provided on the outer periphery of the connecting part 42, and the first sealing member 50 has a protrusion 51 on the side facing the connecting part 42, and the protrusion 51 is embedded in the sealing groove 421.

[0032] It is understandable that, in order to further improve the sealing performance of the connection between the connecting part 42 and the outer shell 10, a sealing groove 421 can be provided on the outer periphery of the connecting part 42, or multiple sealing grooves 421 arranged at intervals can be provided. Each sealing groove 421 is provided around the body of the connecting part 42. The same number of protrusions 51 as the sealing grooves 421 are provided on the inner side of the first sealing member 50. The protrusions 51 surround the connecting part 42, and each protrusion 51 can be embedded in a sealing groove 421. Through the tight cooperation of the two, the sealing effect can be further improved, and foreign objects can be prevented from entering the interior of the mounting cavity 12 through the through hole 11.

[0033] Please see Figure 1 , Figure 2 and Figure 9 In conjunction with the above embodiments, in some embodiments, the blocking assembly 40 includes a plate portion 43 and a plurality of mounting portions 44. The plate portion 43 is located outside the housing 10 and covers the through hole 11. The plate portion 43 is connected to the side of the connecting portion 42 opposite to the abutment portion 41. The plurality of mounting portions 44 are respectively located on both sides of the plate portion 43 along the third direction Z and are connected to the plate portion 43. The plurality of mounting portions 44 are respectively disposed on both sides of the housing 10 along the third direction Z. Each mounting portion 44 has a snap-fit ​​hole 441. The housing 10 is provided with a plurality of snap-fit ​​blocks 13 on both sides along the third direction Z. The snap-fit ​​blocks 13 are engaged with the corresponding snap-fit ​​holes 441.

[0034] It is understood that the plate portion 43 on the blocking assembly 40 is connected to the side of the connecting portion 42 away from the abutment portion 41. Moving the plate portion 43 can drive the connecting portion 42 and the abutment portion 41 to move. At the same time, the plate portion 43 covers the opening of the through hole 11, which can also play a certain sealing role, blocking external water stains and dust, and preventing water stains and dust from entering the interior of the mounting cavity 12 through the through hole 11. Multiple mounting portions 44 are respectively provided on both sides of the plate portion 43 along the third direction Z. When the blocking assembly 40 is connected to the housing 10, the multiple mounting portions 44 are respectively located on both sides of the housing 10 along the third direction Z. Each mounting portion 44 is provided with a snap-fit ​​hole 441. At the same time, multiple snap-fit ​​blocks 13 are respectively provided on both sides of the housing 10 along the third direction Z. The snap-fit ​​blocks 13 can snap with the corresponding snap-fit ​​holes 441, thereby achieving a stable connection between the blocking assembly 40 and the housing 10, and ensuring the stability of the connecting portion 42 and the abutment portion 41.

[0035] Please see Figure 4 , Figure 5 and Figure 6 In conjunction with the above embodiments, in some embodiments, the support portion 21 includes a mounting base 211 and at least one partition plate 212.

[0036] Mounting base 211 is located inside and connected to housing 10. Mounting base 211 has a plurality of first sub-cavities 121 spaced apart along a third direction Z. The first sub-cavities 121 extend along a first direction X. Partition plate 212 is connected to one side of mounting base 211 in the first direction X. Partition plate 212 is disposed between two adjacent first sub-cavities 121. The partition plate 212 encloses the housing 10 on both sides along the third direction Z to form a plurality of second sub-cavities 122. Each second sub-cavity 122 communicates with one first sub-cavity 121. Each second sub-cavity 122 and one first cavity 121 combine to form mounting cavity 12.

[0037] It is understood that the support portion 21 is used to enclose and form multiple mounting cavities 12 with the outer casing 10, and the mounting cavities 12 are used for the corresponding terminal assemblies 30 to pass through. A mounting base 211 is provided on the support portion 21. The mounting base 211 has multiple first sub-cavities 121 extending along the first direction X. At the same time, at least one partition plate 212 is also provided on the support portion 21. Each partition plate 212 is provided on one side of the mounting base 211 in the first direction X and is located between two adjacent first sub-cavities 121 on the mounting base 211. If only one partition plate 212 is provided, the mounting base 211 has two first sub-cavities 121. One partition plate 212 and the outer casing 10 can enclose and form two second sub-cavities 122. The two second sub-cavities 122 are respectively provided with two corresponding first sub-cavities 121 and are interconnected. The second sub-cavities 122 and the first cavities 121 combine to form the mounting cavity 12 mentioned above, which is used for the corresponding terminal assembly 30 to pass through. If multiple partition plates 212 are provided, the mounting base 211 is provided with three or more first sub-cavities 121. The partition plates 212 and the outer shell 10 can be enclosed to form a second sub-cavity 122. Two adjacent partition plates 212 and the outer shell 10 can also be enclosed to form a second sub-cavity 122 (not shown in the figure), thereby forming three or more second sub-cavities 122. Each second sub-cavity 122 is correspondingly provided with a first sub-cavity 121 and is interconnected. The second sub-cavities 122 and the first sub-cavities 121 are combined to form the mounting cavity 12 mentioned above, which is used for the corresponding terminal assembly 30 to pass through.

[0038] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the partition plate 212 includes two arc-shaped surfaces 2121 arranged opposite to each other along a third direction Z. The support portion 21 includes a plurality of first protrusions 213, with at least one first protrusion 213 connected to each arc-shaped surface 2121. The first protrusions 213 are engaged with the terminal assembly 30. The limiting portion 22 includes a body 221 and a second protrusion 222 connected to each other. The body 221 is connected to the mounting base 211 and is disposed on the same side of the mounting base 211 as the partition plate 212. The second protrusion 222 is disposed on the side of the body 221 facing the corresponding terminal assembly 30 and is engaged with the terminal assembly 30.

[0039] Understandably, the two opposite sides of the partition plate 212 along the third direction Z can be configured as arc-shaped surfaces 2121, which can fit with the arc-shaped surface of the corresponding terminal assembly 30, providing better support for the terminal assembly 30 and improving its stability during use to a certain extent. One or more first protrusions 213 can be provided on each arc-shaped surface 2121. Through the snap-fit ​​engagement of the first protrusions 213 with the corresponding terminal assembly 30, the terminal assembly 30 can be limited, preventing it from easily moving in the first direction X. The body 221 of the limiting part 22 is connected to the mounting base 211, which supports the body 221. The second protrusion 222 on the limiting part 22 is located on the side of the body 221 facing the corresponding terminal assembly 30, facilitating the snap-fit ​​engagement of the second protrusion 222 with the terminal assembly 30. By having the first protrusion 213 and the second protrusion 222 engage with the recessed structure on the terminal assembly 30, a locking structure can be formed, which reduces the possibility of the terminal assembly 30 being pulled out from the inside of the housing 10 to a certain extent and improves the firmness of the connection between the terminal assembly 30 and the internal structure of the housing 10.

[0040] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, one end of the housing 10 has a first opening 14 communicating with a plurality of mounting cavities 12, and the connector includes a second seal 60 located within the first opening 14 and connected to the housing 10. The second seal 60 is disposed around the terminal assembly 30 for sealingly connecting the terminal assembly 30 and the housing 10.

[0041] It is understood that the outer casing 10 has a first opening 14 at one end along the first direction X. The first opening 14 is connected to multiple mounting cavities 12. During assembly, the terminal assembly 30 can enter the corresponding mounting cavity 12 through the first opening 14. 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 installing the terminal assembly 30, 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 outer casing 10 through the second sealing element 60, improving the sealing effect and preventing external water stains or dust from entering the interior of the outer casing 10 through the first opening 14.

[0042] The second seal 60 and the housing 10 can be integrally formed using a double-shot molding process, so that the 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 housing 10 later, which saves the installation structure of the seal, reduces the assembly structure of the entire connector, and also reduces the assembly steps of the entire connector.

[0043] Please see Figure 1 and Figure 4 In conjunction with the above embodiments, in some embodiments, the connector includes a rear cover assembly 70, which covers the first opening 14 and is connected to the housing 10. At least a portion of the rear cover assembly 70 is embedded in the first opening 14 and abuts against the second seal 60. The rear cover assembly 70 has a plurality of through holes 71 communicating with the first opening 14, and a terminal assembly 30 passes through the interior of each through hole 71.

[0044] Understandably, a rear cover assembly 70 can be provided at one end of the outer casing 10 along the first direction X. The rear cover assembly 70 can cover the position of the first opening 14, and a portion of it is embedded inside the first opening 14, connecting with the second seal 60 inside the first opening 14. This can further improve the installation stability of the second seal 60 and prevent it from falling out of the first opening 14. The rear cover assembly 70 is provided with a plurality of through holes 71 corresponding to the number and position of the mounting cavities 12. Each through hole 71 communicates with the corresponding mounting cavity 12 through the first opening 14, so that each terminal assembly 30 can be inserted through a through hole 71 into the corresponding mounting cavity 12 during assembly.

[0045] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the other end of the housing 10 has a second opening 15 communicating with the mounting cavity 12, the connector includes a third seal 80, the third seal 80 is located in the second opening 15 and connected to the housing 10, and the terminal assembly 30 passes through the third seal 80.

[0046] It is understood that a second opening 15 is provided at the other end of the outer casing 10 along the first direction X. The second opening 15 communicates with multiple mounting cavities 12 and is positioned opposite to the first opening 14. A third sealing element 80 (which can be a sealing material component such as rubber or silicone) is provided inside the second opening 15. The third sealing element 80 has a ring structure. When installing the terminal assembly 30, the terminal assembly 30 can pass through the interior of the third sealing element 80, or one end of the terminal assembly 30 can be embedded inside the third sealing element 80. The third sealing element 80 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 outer casing 10 through the third sealing element 80, thereby improving the sealing effect and preventing external water stains or dust from entering the interior of the outer casing 10 through the second opening 15.

[0047] The third seal 80 and the housing 10 can be integrally formed using a double-shot molding process, so that the housing 10 and the third seal 80 are firmly connected. There is no need to separately process the third seal 80 and then connect it to the housing 10, which saves the installation structure of the seal, reduces the assembly structure of the entire connector, and also reduces the assembly steps of the entire connector.
