Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to a connector assembly for vehicles and a vehicle. Background Technology

[0002] With the increasing level of automotive electronics, the reliability and stability of electrical connectors in vehicles are crucial to the performance of the entire vehicle's electrical system. Automobiles are intelligent mobile terminals integrating a large number of advanced electronic devices and systems. From engine management systems and electronic stability control systems to autonomous driving assistance systems and in-vehicle infotainment systems, various electronic modules and sensors are widely used in automobiles. They transmit data and exchange signals through complex electrical networks, making the entire vehicle's electrical system increasingly large and complex.

[0003] In related technologies, the limiting fit between the connecting terminal and the sheath is simple and lacks an effective limiting mechanism. During vehicle assembly, if the cable is pulled, the connecting terminal can easily detach from the sheath, leading to poor contact and affecting the normal operation of the vehicle's electrical system. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a connector assembly for vehicles. According to this invention, the connector assembly effectively prevents cable pulling forces from acting on the connection between the connecting terminal and the inner sheath, ensuring that the connecting terminal and the inner sheath are firmly fixed and guaranteed, thus ensuring reliable and stable electrical connections in the vehicle.

[0005] This utility model also proposes a vehicle having the above-described connector assembly.

[0006] The connector assembly according to this utility model is used in a vehicle. The connector assembly includes: an inner sheath, the inner sheath having a terminal mating hole formed therein, and a first limiting member forming on the inner wall of the terminal mating hole; a connecting terminal, the connecting terminal being inserted into the terminal mating hole, and a second limiting member forming on the connecting terminal that mates with the first limiting member; a cable, one end of the cable being connected to the connecting terminal, and a third limiting portion forming on the outer periphery of the cable; and an outer sheath, the outer sheath being sleeved on the outer periphery of the cable and mating with the inner sheath, and a fourth limiting portion forming inside the outer sheath that abuts against the third limiting portion axially.

[0007] According to the connector assembly of this utility model, when the connector assembly is assembled, the connecting terminal with the cable is first inserted into the terminal mating hole of the inner sheath. The second limiting component on the connecting terminal and the first limiting component on the inner wall of the mating hole of the inner sheath cooperate with each other to achieve limiting and fixing between the connecting terminal and the inner sheath. Then, the outer sheath is fitted onto the outer circumference of the cable, and the outer sheath mates with the inner sheath. At this time, the fourth limiting part inside the outer sheath abuts against the third limiting part on the outer circumference of the cable in the axial direction, restricting the axial movement of the cable within the outer sheath. If the cable is pulled, the resistance generated by the abutment action of the third and fourth limiting parts first prevents the cable from continuing to move in the pulling direction within the outer sheath. The pulling force will not directly act on the connection between the connecting terminal and the inner sheath, so that the connecting terminal can be stably held in the terminal mating hole. The mating relationship between the first and second limiting components will not be damaged by the cable pulling, thereby ensuring that the limiting and fixing between the connecting terminal and the inner sheath remains stable.

[0008] According to some embodiments of the present invention, the third limiting part is constructed to protrude radially from the outer surface of the cable, and a first stop surface is formed on the third limiting part in the axial direction; a cable mounting hole for accommodating the cable is formed inside the outer sheath, the cable mounting hole includes at least two hole segments with different diameters, a stepped surface is formed between the two hole segments, and the stepped surface abuts against the first stop surface in the axial direction.

[0009] According to some embodiments of the present invention, the third limiting part is constructed as a shielding ring sleeved on the cable, and the shielding ring is constructed as a metal part.

[0010] According to some embodiments of the present invention, the shielding ring includes: a first segment, which is press-fitted onto the outer surface of the cable and is interference-fitted with the outer surface of the cable; and a second segment, which is connected to the first segment and has a diameter greater than that of the first segment, wherein at least one end of the second segment in the axial direction forms the first stop surface.

[0011] According to some embodiments of the present invention, the first limiting component is configured to have a second stop surface in the axial direction with the inner sheath, and the second limiting component is configured to be an elastic limiting rib disposed on the outer periphery of the connecting terminal and radially expandable. The elastic limiting rib expands after the connecting terminal moves to the terminal mating hole, and the end of the elastic limiting rib abuts against the second stop surface to restrict the connecting terminal from disengaging.

[0012] According to some embodiments of the present invention, the outer sheath is sleeved on at least a portion of the outer periphery of the inner sheath, the outer peripheral wall of the inner sheath has a snap-fit ​​protrusion, and the inner wall of the outer sheath has a snap-fit ​​groove for engaging with the snap-fit ​​protrusion.

[0013] According to some embodiments of the present invention, a surrounding shell is formed on the outer periphery of the outer sheath, and a mating cavity is defined between the outer shell and the outer sheath, the mating cavity being suitable for insertion with an external device.

[0014] According to some embodiments of the present invention, the outer periphery of the outer shell or the outer sheath is formed with positioning holes for positioning the external device.

[0015] According to some embodiments of the present invention, the positioning hole and the snap-fit ​​groove are correspondingly provided and constructed as a through hole penetrating the outer sheath.

[0016] Therefore, in the connector assembly according to this utility model embodiment, when the connecting terminal is inserted into the terminal mating hole, the second limiting component and the first limiting component cooperate to achieve a limiting effect. When the outer sheath is fitted onto the cable and mates with the inner sheath, the fourth limiting part and the third limiting part abut against each other to achieve axial limiting of the cable. If the cable is pulled, the first resistance is generated by the stop action of the third and fourth limiting parts, preventing the cable from continuing to move in the pulling direction within the outer sheath. The pulling force will not directly act on the connection between the connecting terminal and the inner sheath, allowing the connecting terminal to be stably held within the terminal mating hole. The mating relationship between the first and second limiting components will not be damaged by cable pulling, thereby ensuring that the limiting fixation between the connecting terminal and the inner sheath remains stable. During the assembly of the connector assembly, the cable is inserted into the cable mounting hole of the outer sheath. Because the third limiting part protrudes radially from the outer surface of the cable, when the cable is inserted to a certain position, the third limiting part will enter the larger diameter section of the cable mounting hole. The larger diameter section allows the third limiting part to pass through, while the smaller diameter section restricts the movement of the third limiting part but allows other parts of the cable to pass through. Therefore, when the third limiting part moves to the stepped surface, the first stop surface on the third limiting part will contact and abut axially with the stepped surface between the two sections. When the cable is subjected to axial tensile force, the interaction force between the first stop surface and the stepped surface will prevent the cable from moving further, thereby limiting the axial displacement of the cable within the outer sheath. By constructing the third limiting part as a shielding ring, the functions of limiting and electromagnetic shielding are integrated, reducing the number of components in the connector assembly, simplifying the structure, and reducing costs. The second segment is connected to the first segment, and the diameter of the second segment is larger than that of the first segment, causing the second segment to protrude from the outer surface of the cable. At least one end of the second segment has a first stop surface formed axially, allowing the shielding ring to abut axially with the stepped surface, achieving the limiting effect. When the cable is subjected to axial tension, the first stop surface abuts against the stepped surface of the outer sheath, effectively dispersing the tension and preventing the pulling force from acting on the mating parts of the connection terminal and the inner sheath, thus improving reliability.

[0017] The vehicle according to the present invention is briefly described below.

[0018] The vehicle according to the present invention includes the connector assembly described in any of the above embodiments. Because the vehicle according to the present invention includes the connector assembly described in any of the above embodiments, the vehicle according to the present invention can effectively prevent cable pulling from causing the connection terminals to loosen, ensuring the stability and reliability of the connector assembly.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In related technologies, the limiting fit between the connecting terminal and the sheath is simple and lacks an effective limiting mechanism. During vehicle assembly, if the cable is pulled, the connecting terminal can easily detach from the sheath, leading to poor contact and affecting the normal operation of the vehicle's electrical system.

[0025] The following is for reference. Figures 1-5 The connector assembly 1 according to an embodiment of the present utility model is described.

[0026] like Figures 1-5 As shown, the connector assembly 1 according to this utility model is used in a vehicle. The connector assembly 1 includes an inner sheath 11, a connecting terminal 12, a cable 13, and an outer sheath 14. The inner sheath 11 is used to accommodate and fix the connecting terminal 12. A terminal mating hole is formed inside the inner sheath 11, providing space for the insertion of the connecting terminal 12. A first limiting member is formed on the inner wall of the terminal mating hole, which is used to mate with a second limiting member on the connecting terminal 12.

[0027] The connecting terminal 12 is responsible for making electrical connections with other connecting terminals 12 in the vehicle's electrical system to achieve power or signal transmission. The connecting terminal 12 is inserted into a terminal mating hole, and a second limiting member is formed on the connecting terminal 12 to mate with the first limiting member. When the connecting terminal 12 is inserted into the terminal mating hole, the second limiting member and the first limiting member cooperate with each other to achieve a limiting effect.

[0028] Cable 13 is responsible for transmitting power or signals to different locations. One end of cable 13 is connected to connection terminal 12. A third limiting part is formed on the outer periphery of cable 13. The third limiting part is used to cooperate with a fourth limiting part inside the outer sheath 14 to limit the axial movement of cable 13 within the outer sheath 14.

[0029] The outer sheath 14 is fitted around the outer periphery of the cable 13 and cooperates with the inner sheath 11 to protect the cable 13 and the connecting terminal 12. The outer sheath 14 has a fourth limiting part that abuts against the third limiting part in the axial direction. When the outer sheath 14 is fitted onto the cable 13 and cooperates with the inner sheath 11, the fourth limiting part abuts against the third limiting part to achieve axial limiting of the cable 13.

[0030] When the connector assembly 1 is assembled, the connecting terminal 12, to which the cable 13 is connected, is first inserted into the terminal mating hole of the inner sheath 11. The second limiting component on the connecting terminal 12 engages with the first limiting component on the inner wall of the mating hole of the inner sheath 11, thereby limiting and fixing the connecting terminal 12 and the inner sheath 11. Then, the outer sheath 14 is fitted onto the outer periphery of the cable 13, and the outer sheath 14 mates with the inner sheath 11. At this time, the fourth limiting part inside the outer sheath 14 abuts axially with the third limiting part on the outer periphery of the cable 13, restricting the axial movement of the cable 13 within the outer sheath 14.

[0031] If the cable 13 is pulled, the resistance generated by the stop action of the third and fourth limiting parts will prevent the cable 13 from continuing to move in the pulling direction within the outer sheath 14. The pulling force will not directly act on the connection between the connecting terminal 12 and the inner sheath 11, so that the connecting terminal 12 can be stably kept in the terminal mating hole. The mating relationship between the first limiting part and the second limiting part will not be damaged by the pulling of the cable 13, thereby ensuring that the limiting fixation between the connecting terminal 12 and the inner sheath 11 remains stable.

[0032] Therefore, the connector assembly 1 according to this utility model can effectively prevent the cable 13 from exerting a pulling force on the connection between the connecting terminal 12 and the inner sheath 11, ensuring that the connecting terminal 12 and the inner sheath 11 are fixed and securely positioned, and ensuring reliable and stable electrical connection of the vehicle.

[0033] According to some embodiments of this utility model, such as Figures 1-4 As shown, the third limiting part is constructed to protrude radially from the outer surface of the cable 13, and a first stop surface is formed on the third limiting part in the axial direction. The first stop surface is a surface for abutting against the stepped surface 142 inside the outer sheath 14.

[0034] The outer sheath 14 has a cable mounting hole 141 for accommodating the cable 13 inside. The cable mounting hole 141 includes at least two hole segments with different diameters. Due to the change in hole diameter, a stepped surface 142 is formed between the two hole segments. The stepped surface 142 abuts against the first stop surface in the axial direction.

[0035] During the assembly of connector assembly 1, cable 13 is inserted into cable mounting hole 141 of outer sheath 14. Since the third limiting part protrudes radially from the outer surface of cable 13, when cable 13 is inserted to a certain position, the third limiting part enters the larger diameter section of the cable mounting hole 141. The larger diameter section allows the third limiting part to pass through, while the smaller diameter section restricts the movement of the third limiting part but allows other parts of cable 13 to pass through. Therefore, when the third limiting part moves to the stepped surface 142, the first stop surface on the third limiting part contacts and abuts against the stepped surface 142 between the two sections axially. When cable 13 is subjected to axial tensile force, the interaction force between the first stop surface and the stepped surface 142 prevents cable 13 from continuing to move, thereby limiting the axial displacement of cable 13 within outer sheath 14.

[0036] According to some embodiments of this utility model, such as Figure 4 As shown, the third limiting part is constructed as a shielding ring 131 sleeved on the cable 13. The shielding ring 131 can tightly wrap around the outer periphery of the cable 13, forming a stable connection with the cable 13. As the third limiting part, the shielding ring 131 can cooperate with the outer sheath 14 to achieve axial limiting of the cable 13.

[0037] The shielding ring 131 is constructed of metal and possesses excellent electromagnetic shielding performance. The shielding ring 131 effectively shields against external electromagnetic interference, reducing the impact of electromagnetic signals on the power or signals transmitted within the cable 13, and improving the stability and reliability of signal transmission. Simultaneously, the shielding ring 131 also prevents signals within the cable 13 from radiating outwards, reducing interference to other electronic equipment.

[0038] By constructing the third limiting part as a shielding ring 131, the functions of limiting and electromagnetic shielding are integrated, reducing the number of parts in the connector assembly 1, simplifying the structure, and reducing costs.

[0039] According to some embodiments of this utility model, such as Figure 4As shown, the shielding ring 131 includes a first segment 1311 and a second segment 1312. The first segment 1311 is press-fitted onto the outer surface of the cable 13, with an interference fit between the first segment 1311 and the outer surface of the cable 13. Specifically, the inner diameter of the first segment 1311 is slightly smaller than the outer diameter of the cable 13. During installation, a certain pressure is applied to fit the first segment 1311 onto the cable 13, ensuring a tight contact between the two and guaranteeing a reliable connection between them. The interference fit between the first segment 1311 and the outer surface of the cable 13 improves the fixing strength of the shielding ring 131 and enhances the electromagnetic shielding effect, preventing signal interference.

[0040] The second segment 1312 is connected to the first segment 1311, and the diameter of the second segment 1312 is larger than that of the first segment 1311, causing the second segment 1312 to protrude from the outer surface of the cable 13. At least one end of the second segment 1312 has a first abutment surface in the axial direction, allowing the shielding ring 131 to axially abut against the stepped surface 142, achieving a limiting effect. When the cable 13 is subjected to axial tension, the first abutment surface abuts against the stepped surface 142 of the outer sheath 14, effectively dispersing the tension and preventing the pulling force from acting on the mating part between the connecting terminal 12 and the inner sheath 11, thus improving reliability.

[0041] According to some embodiments of this utility model, such as Figure 4 As shown, the first limiting component is constructed with a second abutment surface axially aligned with the inner sheath 11. This second abutment surface provides stable support and abutment position for the elastic limiting rib 121, ensuring effective limiting when the connecting terminal 12 is subjected to external force. The second limiting component is constructed as an elastic limiting rib 121 disposed on the outer periphery of the connecting terminal 12 and radially expandable. The elastic limiting rib 121 has the characteristic of being radially expandable. When the elastic limiting rib 121 is in a contracted state, its size can be reduced, facilitating the smooth entry of the connecting terminal 12 into the terminal mating hole.

[0042] The elastic limiting rib 121 unfolds after the connecting terminal 12 moves into the terminal mating hole. The end of the elastic limiting rib 121 abuts against the second stop surface to prevent the connecting terminal 12 from disengaging. When the elastic limiting rib 121 is compressed within the terminal mating hole, it remains in a contracted state. However, once the connecting terminal 12 is installed in the terminal mating hole, the compression on the elastic limiting rib 121 is released, allowing it to unfold under its own elastic restoring force. The unfolded end of the elastic limiting rib 121 abuts against the second stop surface on the inner sheath 11, thereby preventing the connecting terminal 12 from disengaging from the terminal mating hole.

[0043] It should be noted that the contact limiting effect of the third and fourth limiting parts generates more resistance than the elastic limiting effect of the first and second limiting parts. Therefore, the contact limiting effect of the third and fourth limiting parts can more effectively prevent the connecting terminal 12 from disengaging. Furthermore, when the cable 13 is pulled, the resistance is first generated by the stop effect of the third and fourth limiting parts. The stronger resistance formed by the rigid contact of the third and fourth limiting parts prevents the pulling force from being transmitted to the connection between the connecting terminal 12 and the inner sheath 11. The pulling force will not act directly on the connection between the connecting terminal 12 and the inner sheath 11, ensuring the continuity and stability of signal or power transmission.

[0044] Specifically, the contact limiting effect of the third and fourth limiting parts generates approximately 1.5 times the resistance compared to the elastic limiting effect of the first and second limiting parts.

[0045] According to some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the outer sheath 14 is fitted onto at least a portion of the outer periphery of the inner sheath 11. The outer peripheral wall of the inner sheath 11 has a snap-fit ​​protrusion, and the inner wall of the outer sheath 14 has a snap-fit ​​groove for engaging with the snap-fit ​​protrusion. The engagement of the snap-fit ​​protrusion and the snap-fit ​​groove enables axial positioning between the inner and outer sheaths 14, preventing relative displacement between them in the axial direction.

[0046] The snap-fit ​​protrusion elastically deforms when the inner sheath 11 is inserted into the outer sheath 14, facilitating its smooth entry into the snap-fit ​​groove. When the inner sheath 11 moves to the predetermined position, the snap-fit ​​protrusion, under its own elastic restoring force, forms a stable snap-fit ​​with the snap-fit ​​groove. The snap-fit ​​engagement between the snap-fit ​​protrusion and the snap-fit ​​groove effectively maintains the connection stability between the inner sheath 11 and the outer sheath 14. Furthermore, when disassembly is required, separation can be achieved by applying external force to disengage the snap-fit ​​protrusion from the snap-fit ​​groove. The engagement structure of the snap-fit ​​protrusion and the snap-fit ​​groove is simple and reliable, ensuring both ease of assembly and connection strength.

[0047] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a surrounding shell 143 is formed around the outer periphery of the outer sheath 14. A mating cavity 144 is defined between the shell 143 and the outer sheath 14. The mating cavity 144 is an axially extending annular structure. The mating cavity 144 is suitable for insertion with an external device 15. The mating cavity 144 provides fitting space for the insertion of the outer sheath 14 and the external device 15. Since the mating cavity 144 is an axially extending annular structure, the external device 15 can be smoothly inserted into the mating cavity 144 along the axial direction. After the external device 15 is inserted, the shell 143 will form a stable mating relationship with the external device 15.

[0048] By inserting the external device 15 into the mating cavity 144, the housing 143 can accommodate and fix the external device 15, so that the external component is installed at the end of the connecting terminal 12, thereby protecting the connecting terminal 12.

[0049] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer casing 143 or outer sheath 14 has positioning holes formed on its outer periphery for positioning the external device 15. Correspondingly, the external device 15 has positioning protrusions that fit into the positioning holes, and the positioning protrusions have shapes and sizes adapted to the positioning holes. When the external device 15 is assembled to the outer sheath 14, the positioning protrusions can be inserted into the positioning holes to achieve positioning.

[0050] The relative position between the external component 15 and the outer sheath 14 can be quickly and accurately determined by the cooperation of the positioning hole and the positioning protrusion, making assembly simple.

[0051] Furthermore, the positioning protrusion has the characteristic of being elastically deformable in the radial direction, allowing it to deform appropriately during assembly and easily embed into the positioning hole. When the external component 15 moves to the preset installation position, the positioning protrusion on the external component 15 moves to the positioning hole and the pressure on the positioning protrusion is released. The elastic element unfolds and resets itself by its own restoring force and embeds into the positioning hole, forming a stable limiting fit with the positioning hole, making assembly simple.

[0052] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the positioning hole and the snap-fit ​​groove are correspondingly provided and constructed as a through hole 145 extending through the outer sheath 14. The through hole 145 serves both as a positioning hole, used to engage with the positioning protrusion of the external device 15 for radial positioning, and as a snap-fit ​​groove, used to engage with the snap-fit ​​protrusion of the inner sheath 11 for axial positioning. By integrating the positioning hole and the snap-fit ​​groove into the through hole 145, the processing technology of the outer sheath 14 is simplified and the structural integration is improved.

[0053] According to some embodiments of this utility model, such as Figure 5 As shown, the outer sheath 14 has a receiving cavity formed at the end opposite to the connecting terminal 12; the connector assembly 1 also includes a sealing ring 16, which is disposed within the receiving cavity. The outer peripheral wall of the sealing ring 16 is tightly fitted with the inner wall of the receiving cavity to form a radial seal.

[0054] The sealing ring 16 can be made of an elastic material, such as rubber or silicone, allowing it to deform elastically under pressure to enhance the sealing effect. The cross-sectional shape of the sealing ring 16 can be designed as an O-shape, rectangle, or irregular shape to meet different sealing requirements.

[0055] According to some embodiments of this utility model, such as Figure 5 As shown, the connector assembly 1 also includes an end cap 17, which is disposed at the end of the outer sheath 14 opposite to the connecting terminal 12. The end cap 17 is fitted around the outer periphery of the cable 13 and prevents the sealing ring 16 from disengaging from the receiving cavity. The end cap 17 is connected to the end of the outer sheath 14, forming an axial compression of the sealing ring 16, ensuring that the sealing ring 16 is stably held in the receiving cavity and maintains good sealing performance.

[0056] Furthermore, the stepped surface 142 increases the contact area between the sealing ring 16 and the outer sheath 14. After the end cap is assembled, the end cap and the stepped surface 142 exert stable and uniform pressure on the sealing ring 16 from different directions, allowing the sealing ring to fully fill the gap between it, the outer sheath 14, and the end cap 17. This results in a better and more stable sealing effect, effectively preventing dust, moisture, and other impurities from entering the connector assembly 1, avoiding damage to internal electrical components, and ensuring the normal operation and service life of the connector assembly 1.

Since the vehicle according to the present invention includes the connector assembly 1 in any of the above embodiments, the vehicle according to the present invention can effectively prevent the cable 13 from being pulled, thus preventing the connection terminal 12 from becoming loose, and ensuring the stability and reliability of the connector assembly 1.
