Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a connector assembly and a vehicle having the connector assembly. Background Technology

[0002] For unshielded wires, proper matching of terminals and vehicle mounting holes is achieved by keeping the terminals and connector bodies in the correct positions. The terminals and wires are connected by soldering or crimping and can be regarded as a whole.

[0003] In existing technologies, the connector body and the wire are only fixedly connected by a support ring. The support ring and the wire are fixedly connected by crimping, which has a small holding force. During vehicle assembly, when the wire is pulled, the connector body may slide relative to the wire due to insufficient holding force, causing dimensional changes from the terminal to the connector body. This makes it impossible to assemble the vehicle and fails to meet actual assembly requirements. Furthermore, the holding force of the support ring can only be increased by reducing the crimping height. If the crimping height is too low, the insulation performance will decrease, the wire sheath will be punctured, and safety hazards will be caused. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is for reference. Figures 1-9The connector assembly 100 according to an embodiment of the present invention improves the holding force between the connector body 1 and the connector harness 2, so that the relative position of the connector body 1 and the connector harness 2 is always fixed, preventing relative movement between the connector body 1 and the connector harness 2, thereby making the performance of the connector assembly 100 more reliable and able to meet higher assembly requirements.

[0024] like Figures 1-9 As shown, a connector assembly 100 according to an embodiment of the present invention includes: a connector body 1, a connector wire harness 2, a support ring 3, and a wire clamp assembly 4.

[0025] The connector body 1 is the core functional unit of the connector assembly 100. It mainly undertakes the functions of electrical connection and signal transmission, mechanical fixation and structural support, safety isolation and protection, ensuring reliable connection between the terminal and the connector harness 2, and preventing relative movement between the connector body 1 and the connector harness 2.

[0026] Connector harness 2 is responsible for transmitting high-voltage electrical energy to high-voltage equipment. It can also integrate control signal lines and sensor data lines to realize control signal and data transmission, and achieve precise control of the high-voltage system. Connector harness 2 is installed in the mounting hole through terminals to realize a complete high-voltage circuit.

[0027] The connector harness 2 is inserted into the connector body 1. The connector body 1 has a through hole inside, and the through hole matches the shape and size of the connector harness 2. Thus, the connector harness 2 can be inserted into the through hole to achieve insertion into the connector body 1, thereby achieving support and installation positioning of the connector harness 2 by the connector body 1.

[0028] Furthermore, the support ring 3 and the wire clamp assembly 4 are spaced apart and installed on the connector body 1 along the extension direction of the connector harness 2, and the support ring 3 and the wire clamp assembly 4 respectively fasten the connector harness 2 to fix the connector harness 2 relative to the connector body.

[0029] Specifically, both the support ring 3 and the wire clamp assembly 4 are used to fix the connector harness 2 and the connector body 1 relative to each other, preventing relative movement between the connector harness 2 and the connector body. (See attached diagram) Figure 2As shown, the support ring 3 and the wire clamp assembly 4 are installed on the connector body 1 at intervals along the extension direction of the connector harness 2, i.e., along the axial direction of the connector harness 2. That is, the support ring 3 and the wire clamp assembly 4 are installed on the connector body 1 at two positions on the connector harness 2, respectively. The support ring 3 and the wire clamp assembly 4 respectively fasten the connector harness 2 to fix the connector harness 2 relative to the connector body 1. Specifically, the support ring 3 fastens the connector harness 2 at one position to fix the connector harness 2 relative to the connector body 1, thus forming the first fixed connection between the connector harness 2 and the connector body 1, providing a barrier between the connector body 1 and the connector harness 2. The clamp assembly 4 secures the connector harness 2 at another location to fix the connector harness 2 relative to the connector body 1, forming a second fixed connection between the connector harness 2 and the connector body 1. This increases the holding force between the connector body 1 and the connector harness 2. Thus, through the two fixed connections, the holding force between the connector body 1 and the connector harness 2 is greatly improved, ensuring that the relative positions of the connector body 1 and the connector harness 2 are always fixed, preventing relative movement between the connector body 1 and the connector harness 2. This makes the performance of the connector assembly 100 more reliable and able to meet higher assembly requirements.

[0030] Therefore, by setting a connector assembly 100 with high holding force, the terminal and connector body 1 can always be kept in a relatively correct position during connector assembly, that is, when the terminal is connected to the mounting hole. This allows the terminal to be accurately inserted into the mounting hole, achieving a reliable connection and preventing relative movement between the connector body 1 and the connector harness 2, which would cause the terminal to be unable to be connected to the mounting hole and result in assembly failure.

[0031] According to the connector assembly 100 of this utility model embodiment, by setting the support ring 3 and the wire clamp assembly 4 respectively to fasten the connector wire harness 2 to fix the connector wire harness 2 relative to the connector body 1, the holding force between the connector body 1 and the connector wire harness 2 is improved, so that the relative position between the connector body 1 and the connector wire harness 2 is always fixed, preventing relative movement between the connector body 1 and the connector wire harness 2, thereby making the performance of the connector assembly 100 more reliable and able to meet higher assembly requirements.

[0032] In some embodiments, the connector body 1 is formed with a wire harness through hole 11 for passing through the connector wire harness 2.

[0033] Specifically, such as Figure 1 , Figure 4 and Figure 6As shown, the interior of the connector body 1 is hollow to form a wire harness through hole 11. The wire harness through hole 11 matches the shape and size of the connector wire harness 2 so that the connector wire harness 2 can be smoothly passed through the connector body 1. At the same time, the support ring 3 and the wire clamp assembly 4 can be installed on the connector body 1 to fix the connector wire harness 2.

[0034] Furthermore, at least a portion of the support ring 3 is located inside the wire harness through hole 11 and is fastened to the connector wire harness 2, while the wire clamp assembly 4 is located outside the wire harness through hole 11 and is fastened to the connector wire harness 2.

[0035] Specifically, the inner diameter of the connector body 1 can be set to be larger than the outer diameter of the connector harness 2, so that the inner wall of the connector body 1 can be spaced a certain distance from the outer wall of the connector harness 2. This provides space for the installation of the support ring 3, the wire clamp assembly 4, and other structural components. After the connector harness 2 and the support ring 3 are tightly fitted together, that is, the inner peripheral wall of the support ring 3 and the outer peripheral wall of the connector harness 2 are tightly and firmly connected, and there will be no relative movement or separation. It can withstand a certain external force, thereby achieving relative fixation between the support ring 3 and the connector harness 2, providing a certain holding force for the connector harness 2 and the connector body 1. Then, part or all of the support ring 3 can be located in the wire harness through hole 11, achieving relative fixation between the connector harness 2 and the connector body 1.

[0036] This allows the wire clamp assembly 4 to be located outside the wire harness through hole 11 and to be tightly fitted with the connector wire harness 2. That is, the inner peripheral wall of the wire clamp assembly 4 and the outer peripheral wall of the connector wire harness 2 are tightly and firmly connected, and there will be no relative movement or separation. It can withstand a certain amount of external force, thereby achieving relative fixation between the wire clamp assembly 4 and the connector wire harness 2, further improving the holding force between the connector wire harness 2 and the connector body 1, and further achieving relative fixation between the connector wire harness 2 and the connector body 1.

[0037] Therefore, by fastening the support ring 3 and the wire clamp assembly 4 to the connector wire harness 2 respectively, the two work together to fix the connector wire harness 2, making the relative position between the connector body 1 and the connector wire harness 2 more stable and the holding force higher, making it less likely for the connector body 1 and the connector wire harness 2 to move relative to each other.

[0038] In actual design, the support ring 3 and the wire clamp assembly 4 can be configured to be interference fit with the connector wire harness 2. That is, the inner diameter of the support ring 3 and the wire clamp assembly 4 can be set to be smaller than the outer diameter of the connector wire harness 2, so that the support ring 3 and the wire clamp assembly 4 can be tightly pressed against the connector wire harness 2 to improve the fastening force.

[0039] In some embodiments, the two ends of the wire harness through hole 11 are respectively configured as a first open end 111 and a second open end 112. At least a portion of the support ring 3 is adapted to extend from the first open end 111 into the wire harness through hole 11 after clamping the connector wire harness (2). The wire clamp assembly 4 presses against the second open end 112 and clamps the connector wire harness 2.

[0040] Specifically, such as Figure 1 and Figure 4 As shown, both ends of the wire harness through hole 11 are set to an open state, with one end being a first open end 111 and the other end being a second open end 112. In actual assembly, the inner diameter of the support ring 3 can be set smaller than the outer diameter of the connector wire harness 2, allowing the inner circumferential wall of the support ring 3 to be in close contact with the outer circumferential wall of the connector wire harness 2. External force causes elastic deformation of the mating surface, forming radial pressure that compresses the connector wire harness 2 radially, thus providing a stable holding force for the connector wire harness 2 and ensuring stable installation. Afterwards, part or all of the support ring 3 can be extended from the first open end 111 into the wire harness through hole 11 to achieve relative fixation between the connector wire harness 2 and the connector body 1.

[0041] The wire clamp assembly 4 can be located outside the wire harness through hole 11 and press against the second open end 112 to press the connector wire harness 2. That is, the wire clamp assembly 4 is set outside the connector body 1. The inner diameter of the wire clamp assembly 4 can be smaller than the outer diameter of the connector wire harness 2 so that the inner peripheral wall of the wire clamp assembly 4 can be in close contact with the outer peripheral wall of the connector wire harness 2. The mating surfaces of the two generate elastic deformation, forming radial pressure, which presses the connector wire harness 2 radially, thereby improving the holding force of the connector wire harness 2 and ensuring that the connector wire harness 2 is more stable. At the same time, the wire clamp assembly 4 presses against the second open end 112 to prevent the connector body 1 from moving, further realizing the relative fixation between the connector wire harness 2 and the connector body 1.

[0042] Therefore, by pressing the connector harness 2 at both ends of the harness through hole 11 with support ring 3 and wire clamp assembly 4 respectively, the misalignment or rotation between the connector harness 2 and the connector body 1 is prevented. Thus, the fixed connection between the connector harness 2 and the connector body 1 is achieved through support ring 3 and wire clamp assembly 4, ensuring the stable position of the connector harness 2.

[0043] In some embodiments, the wire clamp assembly 4 includes a wire clamp 41 and a tail cap 42, the connector wire harness 2 passes through the wire clamp 41 and the tail cap 42, the tail cap 42 is connected to the connector body 1, at least a portion of the wire clamp 41 is inserted into the tail cap 42, and the connector wire harness 2 is gradually radially pressed when at least a portion of the wire clamp 41 is inserted toward the tail cap 42.

[0044] Specifically, such as Figure 4 As shown, the wire clamp assembly 4 includes a wire clamp 41 and a tail cap 42. Both the wire clamp 41 and the tail cap 42 are annular in shape. The wire clamp 41 may have a first through hole, and the tail cap 42 may have a second through hole, so that the connector wire harness 2 can be passed through the first through hole and the second through hole, thereby achieving the effect of the connector wire harness 2 passing through the wire clamp 41 and the tail cap 42. The tail cap 42 is connected to the connector body 1 so that the tail cap 42 and the connector body 1 are connected as an integral structure, and the two remain relatively fixed to prevent relative movement between the tail cap 42 and the connector body 1. At least a portion of the wire clamp 41 can be inserted into the tail cap 42, i.e., as shown in the figure. Figure 5 As shown, the tail cap 42 may have a insertion groove 4222 or an insertion hole, so that at least a portion of the wire clamp 41 can extend into the insertion hole or insertion groove 4222 to achieve insertion engagement between at least a portion of the wire clamp 41 and the tail cap 42. Furthermore, the inner diameter of at least a portion of the wire clamp 41 can be set to be smaller than the outer diameter of the connector wire harness 2. Therefore, when at least a portion of the wire clamp 41 is inserted into the tail cap 42, the tail cap 42 can gradually apply radial pressure to the wire clamp 41 to gradually move the wire clamp 41 toward the connector wire harness 2. Radial clamping, that is, the wire clamp 41 gradually applies radial pressure to the connector wire harness 2, so that the inner wall of the wire clamp 41 is in close contact with the outer peripheral wall of the connector wire harness 2. The wire clamp 41 deforms toward the connector wire harness 2, causing the outer peripheral wall of the connector wire harness 2 to deform, so that at least part of the wire clamp 41 is embedded in the connector wire harness 2, so that the wire clamp 41 stably fixes the connector wire harness 2, thereby preventing axial movement and radial rotation of the connector wire harness 2, and ensuring the stability of the force between the connector body 1 and the connector wire harness 2.

[0045] Thus, through the insertion and engagement of at least a portion of the tail cap 42 and the wire clamp 41, the tail cap 42 applies a radial clamping force to the wire clamp 41 toward the connector wire harness 2, so that at least a portion of the inner peripheral wall of the wire clamp 41 can be embedded in the connector wire harness 2, and the depth of embedding into the connector wire harness 2 is kept stable, thereby ensuring the stability of the holding force and the anti-rotation and anti-slip function of the connector wire harness 2.

[0046] In the actual assembly of the wire clamp assembly 4, the connector body 1 and the connector wire harness 2 can be connected first. Then, the wire clamp assembly 4 is fitted onto the outer periphery of the connector wire harness 2, and then the tail cover 42 is installed, so that at least a part of the wire clamp 41 is inserted into the tail cover 42. During insertion, the tail cover 42 gradually presses the wire clamp 41 radially toward the connector wire harness 2, realizing a tight fit between the connector wire harness 2 and the wire clamp 41. After the insertion fit between the wire clamp 41 and the tail cover 42 is completed, the tail cover 42 is connected to the connector body 1, thereby preventing the tail cover 42 from moving axially, guiding the tail cover 42 to loosen, lose the radial pressing force applied to the wire clamp 41, causing the wire clamp 41 to deform outward, resulting in the wire clamp 41 being unable to press the connector wire harness 2.

[0047] In some embodiments, the wire clamp 41 includes a plurality of first snap-fit ​​portions 411, which are spaced apart circumferentially along the wire clamp 41 and together define a snap-fit ​​space 4111. The connector wire harness 2 passes through the snap-fit ​​space 4111, and the plurality of first snap-fit ​​portions 411 move closer to each other when inserted into the tail cover 42 to clamp the connector wire harness 2.

[0048] Specifically, the wire clamp 41 may include two, three, four, or more first engaging portions 411. The first engaging portions 411 are used to engage the connector wire harness 2. The multiple first engaging portions 411 are spaced apart circumferentially along the wire clamp 41, so that they are relatively evenly distributed along the circumference of the wire clamp 41. This facilitates relatively uniform fixation of the connector wire harness 2 in the circumferential direction, preventing severe deformation of the connector wire harness 2 due to localized stress. Furthermore, the multiple first engaging portions 411 spaced apart circumferentially along the wire clamp 41 together form a engaging space 4111 for the connector wire harness. 2 can be axially inserted into the snap-fit ​​space 4111. When the multiple first snap-fit ​​parts 411 are inserted into the tail cover 42, the tail cover 42 will apply a clamping force to the multiple first snap-fit ​​parts 411, so that the multiple first snap-fit ​​parts 411 move closer to each other radially and circumferentially, so as to make close contact with the connector wire harness 2 and clamp the connector wire harness 2 in the circumferential direction, thereby achieving axial and radial fixation of the connector wire harness 2, preventing the connector wire harness 2 from moving axially and rotating radially, thereby improving the holding force between the connector body 1 and the connector wire harness 2, making the connector wire harness 2 more stable.

[0049] In a specific embodiment, such as Figure 5 As shown, the wire clamp 41 includes ten first engaging portions 411, each first engaging portion 411 having an inwardly protruding engaging protrusion. The ten first engaging portions 411 are spaced apart along the circumference of the wire clamp 41 and together define an engaging space 4111, as shown. Figure 4 As shown, the connector harness 2 passes through the snap-fit ​​space 4111. When the ten first snap-fit ​​parts 411 are inserted into the tail cover 42, the ten snap-fit ​​protrusions move closer to each other to clamp the connector harness 2, so that at least part of the inner side of the ten snap-fit ​​protrusions can be simultaneously embedded in the connector harness 2, thereby fixing the connector harness 2.

[0050] It should be noted that the number of first contact parts 411 is not limited to that described in this embodiment, and can be flexibly set according to actual needs.

[0051] In some embodiments, the wire clamp 41 further includes a limiting pressing portion 412, a plurality of first snap-fit ​​portions 411 are spaced apart and connected to the limiting pressing portion 412, the limiting pressing portion 412 is located outside the tail cover 42 and limits and presses against the end face of the tail cover 42.

[0052] Specifically, such as Figure 4and Figure 5 As shown, the wire clamp 41 also includes a limiting and pressing part 412, and a plurality of first locking parts 411 are circumferentially spaced and connected to the limiting and pressing part 412. The limiting and pressing part 412 extends out of the tail cap 42, as shown. Figure 4 As shown in the left-right direction, the left end face of the limiting pressing part 412 presses against the end face of the tail cover 42 to limit the axial movement of the limiting pressing part 412, thereby limiting the axial movement of the wire clamp 41, so that the wire clamp 41 can maintain a stable clamping force to clamp the connector wire harness 2, thereby improving the reliability and stability of the connector assembly 100.

[0053] In other embodiments, such as Figure 6 As shown, the interference between the first snap-fit ​​part 411 and the connector wire harness 2 can be set to 0.4mm to ensure that the wire clamp 41 can provide a stable holding force after assembly, effectively preventing the connector wire harness 2 from rotating and moving axially.

[0054] In other embodiments, at least a portion of the thickness of the first snap-fit ​​portion 411 is H2 and satisfies: 1mm ≤ H2 ≤ 1.5mm.

[0055] Specifically, such as Figure 5 As shown, the first snap-fit ​​part 411 is constructed as a cantilever structure. The thickness of the part where the first snap-fit ​​part 411 connects with the limiting pressing part 412 is H2. H2 can be set to 1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc., to ensure the strength of the part connected with the limiting pressing part 412, prevent the first snap-fit ​​part 411 from breaking and separating from the limiting pressing part 412, and facilitate assembly.

[0056] In other embodiments, the included angle between two adjacent first snap-fit ​​portions 411 is B and satisfies 30°≤B≤45°.

[0057] Specifically, such as Figure 5 As shown, when ten first snap-fit ​​parts 411 are provided, the included angle B between two adjacent first snap-fit ​​parts 411 can be set to 36° so that the ten first snap-fit ​​parts 411 can be relatively evenly spaced apart along the circumference of the wire clamp 41. At the same time, the contact points between the wire clamp 41 and the connector body 1 are increased to ensure that the wire clamp 41 can provide a stable clamping force, i.e., retaining force after assembly.

[0058] In other embodiments, the distance between two adjacent first snap-fit ​​portions 411 is L2 and satisfies: 1.5mm≤L2≤2.5mm.

[0059] Specifically, the spacing L2 between two adjacent first snap-fit ​​parts 411 can be set to 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc., so that when multiple first snap-fit ​​parts 411 are inserted into the tail cover 42, they can stably move closer to each other to clamp the connector harness 2, prevent interference between multiple first snap-fit ​​parts 411, and thus ensure that the connector harness 2 will not rotate relative to the connector body 1 after assembly.

[0060] In some embodiments, the tail cover 42 includes a main body 421 and a plurality of second snap-fit ​​portions 422. The main body 421 is fitted with a wire clamp 41, and the plurality of second snap-fit ​​portions 422 are distributed around the main body 421 and are respectively snap-fitted with the connector body 1.

[0061] Specifically, such as Figure 5 As shown, the tail cover 42 includes a main body 421 and a plurality of second snap-fit ​​parts 422. The second snap-fit ​​parts 422 can be set to two, three, four or more. The plurality of second snap-fit ​​parts 422 are connected to the tail cover 42 including the main body 421, and the plurality of second snap-fit ​​parts 422 are distributed circumferentially around the main body 421. In this way, when the tail cover 42 is installed, the main body 421 is installed and engaged with the wire clamp 41, and the plurality of second snap-fit ​​parts 422 are respectively engaged with the connector body 1 to realize the snap-fit ​​connection between the tail cover 42 and the connector body 1. This can prevent the tail cover 42 from moving, guide the tail cover 42 to loosen, lose the clamping force applied to the wire clamp 41, cause the wire clamp 41 to deform outward, and cause the wire clamp 41 to fail to clamp the connector wire harness 2. Multiple second snap-fit ​​parts 422 are snap-fitted into the connector body 1 respectively, which facilitates the installation and removal of the tail cover 42. The snap-fit ​​is flexible and convenient. The snap-fit ​​form can be set as a hook and a hole, a buckle and a groove, a protrusion and a hole, etc., which can be flexibly selected.

[0062] In practical design, such as Figure 2 and Figure 3 As shown, a snap-fit ​​protrusion 12 can be provided on the connector body 1, and a snap-fit ​​groove 4221 is provided on the second snap-fit ​​part 422. The snap-fit ​​protrusion 12 on the connector body 1 can extend into the snap-fit ​​groove 4221 on the tail cover 42, realizing the snap-fit ​​engagement between the tail cover 42 and the connector body 1. Thus, the snap-fit ​​engagement between the tail cover 42 and the connector body 1 is achieved through the snap-fit ​​engagement between the groove 4221 and the snap-fit ​​protrusion 12. After the tail cover 42 and the connector body 1 are snap-fitted together, the outer surface of the snap-fit ​​protrusion 12 abuts against the inner wall of the groove 4221 to restrict the rotation and axial movement of the tail cover 42. And, as... Figure 4As shown, the radially outer end face of the limiting pressing part 412 can limit and press against the inner wall of the second snap-fit ​​part 422 of the tail cover 42 to restrict the limiting pressing part 412 from moving outward or deforming, resulting in a reduction of clamping force.

[0063] It should be noted that the first snap-fit ​​part 411 and the main body part 421 of the tail cover 42 can be in a zero-clearance fit, that is, the outer wall of the first snap-fit ​​part 411 and the inner wall of the tail cover 42 are tightly fitted to ensure that the tail cover 42 always presses the first snap-fit ​​part 411, and ensures that the first snap-fit ​​part 411 will not deform outward after assembly, which would reduce the amount of interference between the first snap-fit ​​part 411 and the connector wire harness 2, resulting in a decrease in anti-rotation and anti-move performance.

[0064] In some embodiments, the inner peripheral wall of the support ring 3 is provided with a plurality of inwardly protruding protrusions 31, which press against the connector harness 2.

[0065] Specifically, the inner peripheral wall of the support ring 3 can be provided with two, three, four or even more inwardly protruding protrusions 31. When assembling the support ring 3, the protrusions 31 will come into close contact with the outer peripheral wall of the connector harness 2 and press against the connector harness 2, so that the outer peripheral wall of the connector harness 2 will deform, ensuring that the protrusions 31 and the connecting part are tightly fitted, so as to realize the support ring 3 to support and fix the connector harness 2, and provide a stable holding force for the connector harness 2.

[0066] Furthermore, the protrusions 31 are configured in multiple groups, and the multiple groups of protrusions 31 are distributed sequentially along the axial direction of the support ring 3. Each group has multiple protrusions 31, and the multiple protrusions 31 are distributed sequentially along the circumferential direction of the support ring 3.

[0067] In other words, the protrusions 31 can be set in two, three, four or more groups, with multiple groups of protrusions 31 distributed sequentially along the axial direction of the support ring 3, so that multiple groups of protrusions 31 can press the connector harness 2 at multiple positions in the axial direction, thereby increasing the holding force of the support ring 3 on the connector harness 2 in the axial direction and preventing the connector harness 2 from moving axially.

[0068] Each group of protrusions 31 can have two, three, four or more, and the multiple protrusions 31 are distributed sequentially along the circumference of the support ring 3. That is, the multiple protrusions 31 are distributed at intervals along the circumference of the support ring 3, so that the multiple protrusions 31 can press the connector harness 2 at multiple positions in the circumference of the connector harness 2, thereby improving the holding force of the support ring 3 on the connector harness 2 in the circumference and preventing the connector harness 2 from rotating.

[0069] In a specific embodiment, such as Figure 4 and Figure 5As shown, three sets of protrusions 31 are provided, and the three sets of protrusions 31 are distributed sequentially along the axial direction of the support ring 3. Each set has multiple protrusions 31. For example, the first set can have six protrusions 31, and the second and third sets have four protrusions 31. That is, the number of protrusions 31 in the first set can be greater than the number of protrusions 31 in the second and third sets. With this configuration, the difference in the number of protrusions 31 between the first set and the second and third sets can be used for visual identification and error prevention during the assembly process, thereby improving assembly efficiency and accuracy.

[0070] In some embodiments, such as Figure 7 As shown, the protrusion 31 protrudes inward by a dimension of H1 and satisfies: 0.3mm≤H1≤0.8mm.

[0071] In other words, the inward protrusion dimension H1 of the protrusion 31 can be set to 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, etc. If H1 is set too large, the support ring 3 may not be able to effectively support the connector wire harness 2. If H1 is set too small, the protrusion 31 may not be able to effectively press against the connector wire harness 2 and provide a stable holding force.

[0072] Therefore, by setting the inward protrusion dimension H1 of the protrusion 31 within a reasonable range of 0.3mm to 0.8mm, it is effectively ensured that the support ring 3 can provide stable support force, effectively support the connector harness 2, and at the same time, effectively press the connector harness 2 to provide stable holding force and prevent the connector harness 2 from moving.

[0073] In some embodiments, such as Figure 9 As shown, the protrusion 31 is constructed as a long strip-shaped protrusion, and the included angle between two adjacent protrusions 31 in the circumferential direction of the support ring 3 is A, and satisfies: 30°≤A≤90°.

[0074] Specifically, such as Figure 5 As shown, the protrusion 31 is constructed as an elongated convex bulge. This elongated convex bulge increases the contact area between the protrusion 31 and the connector harness 2, providing a more stable clamping force. For example, when six protrusions 31 are provided, the included angle A between two adjacent protrusions 31 in the circumferential direction of the support ring 3 can be set to 60°, ensuring a relatively uniform distribution of the six protrusions 31 in the circumferential direction of the support ring 3. This prevents interference, effectively increasing the contact area between the protrusions 31 and the connector harness 2, and also facilitating stamping and forming, reducing manufacturing costs and simplifying manufacturing. Correspondingly, when four protrusions 31 are provided, the included angle A between the four protrusions 31 in the circumferential direction of the support ring 3 can be set to 90°, allowing for flexible adjustment based on actual conditions.

[0075] In other embodiments, such as Figure 9 As shown, the distance between two adjacent sets of protrusions 31 is L1, and satisfies: 1mm≤L1≤5mm.

[0076] In other words, the distance L1 between two adjacent sets of protrusions 31 can be set to 1mm, 2mm, 3mm, 4mm or 5mm, etc. It is understandable that if the distance L1 between two adjacent sets of protrusions 31 is set too large, it will not be conducive to providing a stable holding force, and the holding force will be more dispersed. If the distance L1 between two adjacent sets of protrusions 31 is set too small, it will cause interference between the protrusions 31, which is not conducive to manufacturing.

[0077] Therefore, by setting the spacing L1 between two adjacent sets of protrusions 31 within a reasonable range of 1mm to 5mm, it is not only effective to ensure that the contact area between the protrusions 31 and the connector harness 2 is sufficient to provide a stable holding force, but also to facilitate manufacturing and avoid interference between the protrusions 31.

[0078] In other embodiments, a sealing ring 5 can be provided inside the wire harness through hole 11, such as... Figure 4 As shown, the outer peripheral wall of the sealing ring 5 is tightly pressed against the inner peripheral wall of the wire harness through hole 11, and the inner peripheral wall of the sealing ring 5 is tightly pressed against the outer peripheral wall of the connector wire harness 2, so as to achieve the sealing effect of the connector wire harness 2 and prevent external moisture from entering the connector body 1 and affecting the connector wire harness 2.

[0079] This utility model also proposes a vehicle.

[0080] The vehicle according to the present invention includes the connector assembly 100 of any of the above embodiments.

[0081] By setting the support ring 3 and the wire clamp assembly 4 to fasten the connector wire harness 2 to fix the connector wire harness 2 relative to the connector body 1, the holding force between the connector body 1 and the connector wire harness 2 is improved, so that the relative position between the connector body 1 and the connector wire harness 2 is always fixed, preventing relative movement between the connector body 1 and the connector wire harness 2, thereby making the performance of the connector assembly 100 more reliable and able to meet higher assembly requirements.

[0082] The connector assembly 100 in this embodiment is used in high-voltage connectors in vehicles to meet higher vehicle assembly requirements.
