[0004] Technical solution: A connector according to an embodiment of this application includes:
[0005] Plastic components;
[0006] The back cover assembly includes an outer frame portion, a surrounding portion, and a protrusion portion. The outer frame portion has a receiving cavity. One end of the plastic assembly is embedded in the receiving cavity and connected to the outer frame portion. At least a portion of the surrounding portion is located within the receiving cavity and connected to the outer frame portion. The protrusion portion is connected to the side of the surrounding portion facing the plastic assembly and abuts against the plastic assembly.
[0007] In some embodiments, the surrounding portion has a through hole communicating with the receiving cavity; the rear cover assembly includes a plurality of the protrusions disposed around the through hole.
[0008] In some embodiments, the surrounding portion includes a first body and a second body disposed opposite to each other, the first body and the second body forming the through hole, one end of the first body along the height direction of the rear cover assembly being connected to one end of the second body along the height direction, and the other end of the first body along the height direction being spaced apart from the other end of the second body along the height direction; the rear cover assembly includes:
[0009] A connecting portion, one end of which is connected to the other end of the first body along the height direction, and the other end of which is connected to the other end of the second body along the height direction.
[0010] In some embodiments, the surrounding portion has a first side disposed toward the plastic assembly and a second side disposed away from the plastic assembly, the minimum distance from the connecting portion to the first side is H1, and the minimum distance from the connecting portion to the second side is H2, satisfying: H1 = H2.
[0011] In some embodiments, a first gap is formed between the side of the first body away from the second body and the outer frame portion, and the first gap communicates with the receiving cavity; a second gap is formed between the side of the second body away from the first body and the outer frame portion, and the second gap communicates with the receiving cavity.
[0012] In some embodiments, the back cover assembly has a first opening communicating with the first gap on one side along the height direction, and the back cover assembly has a second opening communicating with the second gap on one side along the height direction.
[0013] In some embodiments, the back cover assembly includes two opposing first snap-fit portions, both of which are located within the receiving cavity and are respectively connected to the inner walls of the receiving cavity on both sides along the width direction.
[0014] The plastic component has second snap-fit portions on both sides along the width direction. The second snap-fit portions are located within the receiving cavity.

[0018] Beneficial Effects: The connector of this application embodiment includes: a plastic component; a back cover assembly including an outer frame portion, a surrounding portion, and a protrusion. The outer frame portion has a receiving cavity. One end of the plastic component is embedded in the receiving cavity and connected to the outer frame portion. At least a portion of the surrounding portion is located within the receiving cavity and connected to the outer frame portion. The protrusion is connected to the side of the surrounding portion facing the plastic component and abuts against the plastic component. By providing a protrusion on the side of the surrounding portion facing the plastic component, the distance between the plastic component and the surrounding portion can be filled, allowing one end of the plastic component to abut against the protrusion. Thus, when the connector as a whole vibrates, the plastic component has no space to move in the direction of assembly with the back cover assembly, preventing the plastic component from moving in that direction. This ensures a stable connection between the plastic component and the back cover assembly and avoids noise caused by collision between the plastic component and the back cover assembly when the connector as a whole shakes.

Detailed Implementation
[0031] 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.
[0032] 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.
[0033] As an introduction to the embodiments of this application, a connector is introduced. Connectors play a crucial role in ensuring the normal operation of various vehicle functions. A connector typically includes a plastic component, a rear cover, a connector secondary lock, and terminal secondary locks. From a wire connection perspective, connectors enable reliable connection between the male and female ends of wires, ensuring current transmission. Their applications are even more widespread in electronic and electrical systems, such as connecting sensors, control units, and other components in automotive electronic systems, and connecting the motherboard with various circuit boards, hard drives, and other devices inside a computer to achieve signal transmission and device collaboration. They are important components in constructing electrical and electronic systems. However, after the connector's rear cover is assembled with the plastic component, due to errors in structural processing and assembly, gaps may exist at the connection point between the rear cover and the plastic component. This results in low stability of the connection between the rear cover and the plastic component, and noise may be generated due to vibration (e.g., when the connector is installed on a vehicle, vibrations during vehicle movement may cause collisions between the rear cover and the plastic component, generating noise).
[0034] In view of this, embodiments of this application provide a connector to overcome at least one of the above-mentioned technical problems.
[0035] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the connector includes a plastic assembly 10 and a back cover assembly 20. The back cover assembly 20 includes an outer frame portion 21, a surrounding portion 22, and a protrusion 23. The outer frame portion 21 has a receiving cavity 211. One end of the plastic assembly 10 is embedded in the receiving cavity 211 and connected to the outer frame portion 21. At least a portion of the surrounding portion 22 is located in the receiving cavity 211 and connected to the outer frame portion 21. The protrusion 23 is connected to the side of the surrounding portion 22 facing the plastic assembly 10 and abuts against the plastic assembly 10.
[0036] Understandably, one end of the plastic component 10 is embedded in the receiving cavity 211 of the outer frame portion 21 (the outer frame portion 21 is similar to a U-shaped structure, with the receiving cavity 211 located inside it) and connected to the outer frame portion 21. At this time, after the plastic component 10 is connected to the outer frame portion 21, although the plastic component 10 cannot be easily pulled out of the receiving cavity 211, there is a certain gap between one end of the plastic component 10 and the surrounding portion 22 inside the receiving cavity 211. The plastic component 10 can still move a certain distance towards the surrounding portion 22. This distance is the relative movement distance between the plastic component 10 and the back cover assembly 20. When the connector as a whole vibrates, it may cause the plastic component 10 to move repeatedly within this distance range, or cause the back cover assembly 20 to move repeatedly within this distance range, resulting in collisions between the back cover assembly 20 and the plastic component 10, generating noise. By providing a protrusion 23 on the side of the surrounding portion 22 facing the plastic assembly 10, the distance can be filled, allowing one end of the plastic assembly 10 to abut against the protrusion 23 (wherein, the protrusion 23 can be a structure with a certain elasticity, such as rubber or silicone, which can provide a certain buffering effect against the compression of one end of the plastic assembly 10). Thus, when the connector as a whole vibrates, the plastic assembly 10 in the direction of assembly with the rear cover assembly 20 (e.g., ...) will... Figure 1 There is no space for movement in the direction indicated by the middle arrow, which prevents the plastic component 10 from moving in that direction, ensuring a stable connection between the plastic component 10 and the back cover component 20, and preventing noise caused by collision between the plastic component 10 and the back cover component 20 when the connector as a whole shakes.
[0037] Please see Figure 3 In conjunction with the above embodiments, in some embodiments, the surrounding portion 22 has a through hole 221 communicating with the receiving cavity 211; the rear cover assembly 20 includes a plurality of protrusions 23, which are arranged around the through hole 221.
[0038] It is understandable that the through hole 221 communicating with the receiving cavity 211 is provided on the surrounding portion 22 to facilitate the wire passing through the through hole 221 and the receiving cavity 211 into the interior of the plastic component 10, which is beneficial for the connection between the male and female ends of the wire. At this time, the surrounding portion 22 is roughly arranged around the wire. In order to improve the stability of the connection between the plastic component 10 and the back cover assembly 20, multiple protrusions 23 can be provided on the side of the surrounding portion 22 facing the plastic component 10. The multiple protrusions 23 are arranged around the through hole 221. After the plastic component 10 and the back cover assembly 20 are connected, the multiple protrusions 23 simultaneously abut against different positions on one end of the plastic component 10. Without affecting the connection of the structure and the normal operation of the connector, the multiple protrusions 23 are equivalent to connecting different positions on one end of the plastic component 10 to different positions on one side of the surrounding portion 22. This can further improve the stability of the connection between the plastic component 10 and the surrounding portion 22 and prevent the connection point between the plastic component 10 and the surrounding portion 22 from colliding and generating noise when the connector shakes.
[0039] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the surrounding portion 22 includes a first body 222 and a second body 223 disposed opposite to each other, the first body 222 and the second body 223 surrounding to form a through hole 221, one end of the first body 222 along the height direction X is connected to one end of the second body 223 along the height direction X, and the other end of the first body 222 along the height direction X is spaced apart from the other end of the second body 223 along the height direction X. The rear cover assembly 20 includes a connecting portion 24, one end of the connecting portion 24 is connected to the other end of the first body 222 along the height direction X, and the other end of the connecting portion 24 is connected to the other end of the second body 223 along the height direction X.
[0040] It is understood that the surrounding portion 22 includes a first body 222 and a second body 223, which together form a through hole 221 to facilitate the insertion of wires and provide support for the wires. The bottom ends of the first body 222 and the second body 223 are generally connected to each other, either directly or through the outer frame portion 21. There is generally a certain distance between the top ends of the first body 222 and the top ends of the second body 223 (e.g., ...). Figure 2If a large-diameter wire passes through the through hole 221, due to the spacing, the first body 222 and the second body 223 are not completely connected. The first body 222 and the second body 223 can deform to a certain extent more easily, facilitating the wire's passage. However, this spacing reduces the overall strength of the back cover assembly 20, making it more susceptible to deformation or even damage under external forces. By providing a connecting part 24 between the top of the first body 222 and the top of the second body 223, the tops of the two bodies are connected. The connecting part 24 only connects a portion of the top of the first body 222 to a portion of the top of the second body 223, increasing the connection strength between the tops of the first body 222 and the second body 223. This improves the overall strength of the back cover assembly 20 while ensuring that the first body 222 and the second body 223 can deform to a certain extent (this structural design has better deformation capability than completely connecting the tops of the first body 222 and the second body 223).
[0041] Please see Figure 3 and Figure 4 In conjunction with the above embodiments, in some embodiments, the surrounding portion 22 has a first side 224 disposed toward the plastic assembly 10 and a second side 225 disposed away from the plastic assembly 10, the minimum distance from the connecting portion 24 to the first side 224 is H1, and the minimum distance from the connecting portion 24 to the second side 225 is H2, satisfying: H1=H2.
[0042] It is understood that the first side 224 and the second side 225 are respectively the side of the surrounding portion 22 facing the plastic assembly 10 and the side facing away from the plastic assembly 10. The top of the first body 222 and the top of the second body 223 are connected by the connecting portion 24, and the minimum distance from the connecting portion 24 to the first side 224 and the minimum distance from the connecting portion 24 to the second side 225 are equal, that is, H1 = H2, and both H1 and H2 are greater than zero. In other words, one end of the connecting portion 24 is attached to the middle of the top of the first body 222, and the other end of the connecting portion 24 is attached to the middle of the top of the second body 223. This not only improves the connection strength between the first body 222 and the second body 223, but also facilitates the deformation of the two openings of the through hole 221 (such as in the height direction Y, the top of the first body 222 and the top of the second body 223 deform to a certain extent, causing the through hole 221 to expand to a certain extent), making it easier for wires to pass through the interior of the through hole 221.
[0043] Please see Figure 3In conjunction with the above embodiments, in some embodiments, the side of the first body 222 away from the second body 223 and the outer frame portion 21 form a first gap 226, the first gap 226 communicating with the receiving cavity 211, and the side of the second body 223 away from the first body 222 and the outer frame portion 21 form a second gap 227, the second gap 227 communicating with the receiving cavity 211.
[0044] It is understandable that the first body 222 and the second body 223 are respectively arranged to form a first gap 226 and a second gap 227 between the opposite sides of the first body 222 and the outer frame 21. This arrangement can reduce the thickness of the first body 222 in the width direction Y, and also reduce the thickness of the second body 223 in the width direction Y. Reducing the thickness is more conducive to the deformation of the first body 222 and the second body 223 in the width direction Y, making it easier for the wire to pass through the interior of the through hole 221.
[0045] Please see Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the back cover assembly 20 has a first opening 25 communicating with the first gap 226 on one side along the height direction X, and a second opening 26 communicating with the second gap 227 on one side along the height direction X.
[0046] It is understandable that the first opening 25 can be regarded as the first gap 226 extending along the height direction X, penetrating the opening formed by the first body 222 and the outer frame 21. Similarly, the second opening 26 can be regarded as the second gap 227 extending along the height direction X, penetrating the opening formed by the second body 223 and the outer frame 21. This arrangement can reduce the connection area between the two side walls of the outer frame 21 along the width direction Y and the surrounding part 22, making it easier for the two side walls of the outer frame 21 along the width direction Y to deform. When disassembling the rear cover assembly 20, the outer frame 21 can be rotated, increasing the torque of the rear cover assembly 20, causing the two side walls of the outer frame 21 to deform, which facilitates the release of the restriction between one end of the plastic component 10 and the outer frame 21, so that one end of the plastic component 10 can be separated from the inside of the receiving cavity 211, which is beneficial to the disassembly and assembly of the rear cover assembly 20.
[0047] Please see Figure 8 , Figure 9 and Figure 10In conjunction with the above embodiments, in some embodiments, the back cover assembly 20 includes two opposing first snap-fit portions 27, both of which are located within the receiving cavity 211 and are respectively connected to the inner walls of the receiving cavity 211 on both sides along the width direction Y. The plastic assembly 10 has second snap-fit portions 28 on both sides along the width direction Y, the second snap-fit portions 28 being located within the receiving cavity 211, each second snap-fit portion 28 being located on the side of a first snap-fit portion 27 facing the surrounding portion 22 and abutting against the first snap-fit portion 27.
[0048] It is understood that first snap-fit portions 27 are respectively provided on the inner walls of the receiving cavity 211 on both sides along the width direction Y, and second snap-fit portions 28 are respectively provided at corresponding positions on one end of the plastic component 10. When the plastic component 10 is connected to the outer frame portion 21, the second snap-fit portion 28 exerts a pressing force on the first snap-fit portion 27 along the assembly direction F of the plastic component 10 and a pushing force along the width direction Y. This allows the second snap-fit portion 28 to move to the side of the first snap-fit portion 27 facing the surrounding portion 22, so that the first snap-fit portion 27 can block the second snap-fit portion 28, thereby limiting one end of the plastic component 10 and preventing one end from easily sliding out of the inside of the receiving cavity 211, thus improving the stability of the connection between the plastic component 10 and the outer frame portion 21.
[0049] Please see Figure 8 , Figure 9 and Figure 10 In conjunction with the above embodiments, in some embodiments, the back cover assembly 20 includes two oppositely disposed filling portions 29, each filling portion 29 being located between a second snap-fit portion 28 and the inner wall of a corresponding receiving cavity 211, and connected to both.
[0050] Understandably, after the back cover assembly 20 and the plastic assembly 10 are connected by the first snap-fit portion 27 and the second snap-fit portion 28, there may be a certain gap between one end of the plastic assembly 10 and the corresponding first snap-fit portion 27 or second snap-fit portion 28 in the width direction Y. This gap can cause the plastic assembly 10 or the back cover assembly 20 to wobble in the width direction Y, resulting in collisions between the structures and generating noise. By providing a filling portion 29 between the second snap-fit portion 28 and the inner wall of the receiving cavity 211, the space between the second snap-fit portion 28 and the inner wall of the receiving cavity 211 can be filled, preventing relative movement between the second snap-fit portion 28 and the inner wall of the receiving cavity 211 in the width direction Y, and further improving the stability of the plastic assembly 10 and the back cover assembly 20. The filling portion 29 can be a structure with a certain degree of elasticity, such as rubber or silicone, which can provide a certain buffering effect against the compression of the second snap-fit portion 28.

[0052] A vehicle includes the electrical equipment described above. It possesses all the technical features and beneficial effects of the aforementioned electrical equipment, which will not be elaborated further here.
