[0046] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, these embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the specification. Moreover, the figures can not be to scale and some features can be exaggerated to show details of particular embodiments. Figures in the drawings are provided merely as illustrative and do not necessarily bear a relationship to the scale.

[0047] Unless otherwise defined, or specified in this disclosure, technical terms or scientific terms used in the present disclosure shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The words "a" or "an" or "the" used herein should not be interpreted as having only the identified genus or species, but rather include one or more entities. The words "comprising" and "having" are used herein to mean that an element or feature can be included but not limited to the listed elements or features. The words "first," "second," and the like do not imply a quantity or order but are merely used to identify one of the elements.

[0048] The terms "connected," "fixed," and the like should be construed broadly, for example, "connected" can be fixed connection, or movable connection, or integral connection, or detachable connection, can be directly connected, or indirectly connected through an intermediate medium.

[0049] In the present disclosure, "A part is provided on B part" can be that A part is directly connected with B part, or A part is provided on C part, and C part is provided on B part.

[0050] In the description of the present disclosure, the orientation terms "inner / outer", "width", "height", "thickness", and the like are merely used to represent relative positional relationships. For example, for the sake of convenience, they are defined according to the general understanding of the wiring harness connector, or the orientation of the components shown in the drawings. For example, with reference toFigure 1 As shown in the drawings, the direction in which the wire end sheath 1 is connected with the cable 5, i.e. the axial direction of the cable 5, is taken as the first direction, denoted by X in the drawings; the direction in the plane perpendicular to the first direction is taken as the radial direction. It should be understood that these directional terms are relative concepts, which can change accordingly according to the orientation of the battery pack and the vehicle.

[0051] The present disclosure provides a wiring harness connector, referring to Figures 1 to 10 As shown in the drawings, the wiring harness connector comprises a wire end sheath 1, a cable seal 2, a wire fixing clamp 3 and a cable 5; the wire end sheath 1 has a first wire insertion port 11, through which the cable 5 is connected with the wire end sheath 1; the cable seal 2 is sleeved between the inner wall of the first wire insertion port 11 and the outer wall of the cable 5; wherein the wire end sheath 1, the cable seal 2 and the wire fixing clamp 3 are sequentially sleeved on the cable 5 along the first direction; at least part of the wire fixing clamp 3 is sleeved in the first wire insertion port 11.

[0052] Referring to Figure 2 As shown in the drawings, the outer wall of the cable seal 2 is sleeved on the inner wall of the first wire insertion port 11, and the cable seal 2 has a second wire insertion port 22 for the cable 5 to pass through. The cable seal 2 has elasticity, and the tendency of the cable seal 2 to recover after being pressed can provide sealing for the connection between the wire end sheath 1 and the cable 5, preventing water vapor from entering the wire end sheath 1. The cable seal 2 can be a rubber seal ring, which can include silicone rubber, fluororubber, polyurethane rubber, etc.

[0053] Since the cable seal 2 has elasticity, when it is installed in the first wire insertion port 11 of the wire end sheath 1, it may be abnormally deformed, which is difficult to identify in appearance, and may not have much impact on short-term use, but there is a risk of causing the connector to fail to seal over a long period of use. The present disclosure can use the wire fixing clamp 3 to push the cable seal 2 into the wire end sheath 1, and after the cable seal 2 is installed in the first wire insertion port 11, the wire fixing clamp 3 is also pushed into the first wire insertion port 11, thereby ensuring that the cable seal 2 can be completely installed in the first wire insertion port 11 and be pushed tightly by the wire fixing clamp 3, ensuring the correct assembly of the cable seal 2, avoiding abnormal stress deformation of the cable seal 2, and meeting the sealing performance requirements of the wiring harness connector over a long period of use. In addition, the wiring harness connector structure provided by the present disclosure also has the beneficial effects of simple structure, good assembly, small size, light weight, and low cost.

[0054] In particular, referring to Figures 2 to 4 As shown in the drawings, Figure 2 A cross-sectional view of the wiring harness connector along the cable 5 axis in an exemplary embodiment is shown; Figure 3 As shown in the drawings, Figure 2 An enlarged schematic view of the assembly relationship of the wire end sheath 1, the cable seal 2 and the wire fixing clamp 3 in region F in Figure 4A schematic view of the fixed wire clamp 3 is shown.

[0055] Exemplarily, referring to Figure 2 and Figure 6 , a cross-sectional view of the wire end sheath is shown. The wire end sheath 1 has a wire end accommodating cavity 12, and the first wire insertion port 11 is in communication with the wire end accommodating cavity 12; an inner core sheath is arranged in the wire end accommodating cavity 12, and the cable 5 passes through the first wire insertion port 11 and is connected to the inner core sheath in the wire end accommodating cavity 12. The wire end sheath 1 has a wire insertion end 13, and the first wire insertion port 11 is formed in the wire insertion end 13.

[0056] Exemplarily, referring to Figure 3 , Figure 4 , the fixed wire clamp 3 has an abutting surface 31 on the side close to the cable seal 2; an outer edge of the abutting surface 31 is provided with a first limiting portion 32 protruding from the abutting surface 31, and the abutting surface 31 and the first limiting portion 32 are both arranged in the first wire insertion port 11. During assembly, the cable seal 2 can be pushed into the wire end sheath 1 by the abutting surface 31, specifically, into the wire insertion end 13. After the cable seal 2 is assembled into the first wire insertion port 11, the abutting surface 31 and the first limiting portion 32 are also pushed into the first wire insertion port 11, thereby ensuring that the cable seal 2 can be completely assembled into the first wire insertion port 11. The abutting surface 31 is beneficial to ensure that the cable seal 2 is uniformly stressed and correctly assembled into the first wire insertion port 11, avoiding abnormal deformation of the cable seal 2 caused by being pressed and deviated. The first limiting portion 32 is arranged at the outer edge of the abutting surface 31 and protrudes from the abutting surface 31, as shown in Figure 3 , so that the first limiting portion 32 further presses the area of the cable seal 2 close to the wire insertion end 13 after extending into the first wire insertion port 11, which is beneficial to stably apply pressure to the outer edge of the cable seal 2, avoiding the outer edge of the cable seal 2 from being deviated or bent when entering the wire insertion end 13, causing abnormal deformation such as wrinkles of the outer edge of the cable seal 2, and also enhancing the sealing effect of the edge area of the inner wall of the first wire insertion port 11.

[0057] Exemplarily, referring to Figure 3 , the abutting surface 31 is perpendicular to the first direction X. Exemplarily, the first limiting portion 32 is uniformly and continuously extended along the outer edge of the abutting surface 31, so as to ensure that the first limiting portion 32 uniformly stresses the outer edge of the cable seal 2 when pushing the outer edge of the cable seal 2 into the wire insertion end 13.

[0058] In an exemplary embodiment of the present disclosure, referring to Figure 3 and Figure 5As shown in the schematic diagram of the cable seal 2, the outer periphery of the cable seal 2 has at least one first sealing protrusion 21. For example, the outer periphery of the cable seal 2 has a plurality of first sealing protrusions 21, and the number of the first sealing protrusions 21 can be 2, 3, 4, 5 or more, so that the outer periphery of the cable seal 2 forms a corrugated structure, and when the cable seal 2 is installed in the first wire insertion port 11, the first sealing protrusion 21 is in close contact with the inner wall of the wire insertion end 13.

[0059] For example, referring to Figure 3 As shown, the maximum outer diameter of the first sealing protrusion 21 in the natural state is greater than the inner diameter of the first wire insertion port 11, and the minimum outer diameter of the first sealing protrusion 21 in the natural state is less than the inner diameter of the first wire insertion port 11, so that after the cable seal 2 is installed in the first wire insertion port 11, the top "peak" of the first sealing protrusion 21 is deformed by being pressed by the inner wall of the wire insertion end 13, thereby sealing the first wire insertion port 11. In an exemplary embodiment of the present disclosure, the outer diameter of the first limiting portion 32 is greater than or equal to the minimum outer diameter of the cable seal 2, that is, the outer diameter of the first limiting portion 32 is greater than the outer diameter of the bottom "valley" of the first sealing protrusion 21, so that after the first limiting portion 32 is inserted into the first wire insertion port 11, it can press the first sealing protrusion 21, thereby improving the sealing effect of the edge area of the inner wall of the first wire insertion port 11.

[0060] For example, referring to Figure 3 As shown, the inner diameter of the first limiting portion 32 is not less than the minimum diameter of the cable seal 2, that is, the inner diameter of the first limiting portion 32 is greater than the outer diameter of the bottom "valley" of the first sealing protrusion 21, so that the first limiting portion 32 can provide a stable pushing force to the first sealing protrusion 21, avoid the first sealing protrusion 21 from being wrinkled or bent when it enters the first wire insertion port 11, and avoid the first limiting portion 32 from pressing the non-edge area of the cable seal 2, thereby avoiding excessive compression of the cable seal 2.

[0061] In an exemplary embodiment of the present disclosure, referring to Figure 5 As shown in the schematic diagram of the cable seal 2, the cable seal 2 has a second wire insertion port 22 for the cable 5 to pass through, and the inner wall of the second wire insertion port 22 has at least one second sealing protrusion 23, for example, the inner wall of the second wire insertion port 22 has a plurality of second sealing protrusions 23, and the number of the second sealing protrusions 23 can be 2, 3, 4, 5 or more, so that the inner wall of the second wire insertion port 22 on the cable seal 2 forms a corrugated structure, and when the cable 5 is installed in the second wire insertion port 22, the second sealing protrusion 23 is in close contact with the outer wall of the cable 5, which is conducive to improving the sealing effect between the cable seal 2 and the cable 5 and facilitating the movement of the cable 5 in the second wire insertion port 22 during assembly.

[0062] In an exemplary embodiment of the present disclosure, referring to Figure 6a cross-sectional view of the wire end sheath 1, and Figure 7 a schematic view of the wire end sheath 1, the wire end insertion end 13 has at least one notch portion 14 away from one end of the wire end accommodating cavity 12. Referring to Figure 4 As shown, the wire fixing clip 3 includes a first body portion 33 and a clamping portion 34 protruding in a radial direction from the first body portion 33; the abutting surface 31 and the first limiting portion 32 are both located on the first body portion 33; the clamping portion 34 corresponds to the notch portion 14.

[0063] Referring to Figure 1 As shown, the notch portion 14 can be used when assembling the wire end sheath 1 and the wire fixing clip 3, and the wire fixing clip 3 can be seen from the side to determine whether the wire fixing clip 3 is assembled, avoiding missing the wire fixing clip 3. By cooperating the clamping portion 34 and the notch portion 14, the relative position of the wire end sheath 1 and the wire fixing clip 3 can be determined, ensuring that the wire fixing clip 3 extends into the first wire insertion port 11 to a certain depth, ensuring that the cable seal 2 is stably installed in the correct position, and the cable seal 2 is not excessively compressed.

[0064] Exemplarily, the first limiting portion 32 is used to push the cable seal 2 in a direction close to the wire end accommodating cavity 12 in a first direction to isolate the cable seal 2 from the notch portion 14. Specifically, Figure 8 A schematic view of the wire end insertion end 13 cooperating with the cable seal 2 is shown, and the notch portion 14 is shown for clarity, Figure 8 The wire fixing clip 3 is hidden. Referring to Figure 3 and Figure 8 As shown, the depth of the first limiting portion 32 of the wire fixing clip 3 extending into the first wire insertion port 11 is greater than the depth of the notch portion 14 on the wire end insertion end 13. When the first limiting portion 32 is installed into the first wire insertion port 11, it can push the cable seal 2, specifically, it can push the first sealing protrusion 21, ensuring that the first sealing protrusion 21 is installed in the area of the wire end insertion end 13 without the notch portion 14, avoiding the top "peak" of the first sealing protrusion 21 of the cable seal 2 farthest from the wire end accommodating cavity 12 entering the notch portion 14, and avoiding the failure of sealing in the long-term use process.

[0065] In an exemplary embodiment of the present disclosure, referring to Figure 6 , Figure 7 , Figure 8 As shown, the wire end insertion end 13 includes an extension region 131 and a thinning region 132 formed at one end of the extension region 131 away from the wire end accommodating cavity 12, and the thickness gradually decreases in a direction away from the extension region 131. The thickness of the thinning region 132 described in the present disclosure refers to the size of the thinning region 132 in the radial direction. The thickness of the thinning region 132 gradually decreases in a direction away from the extension region 131, which can avoid the sharp edges of the wire end insertion end 13 scratching the cable seal 2 when assembling the cable seal 2.

[0066] Exemplarily, referring toFigure 7 As shown, the notch 14 penetrates at least a portion of the thinning region 132 and the extension region 131 along the first direction.

[0067] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the cable clamp 3 includes a first main body 33 and a cable assembly ring 35; the cable assembly ring 35 protrudes from the first main body 33 along a first direction on the side away from the cable seal 2. When the cable 5 passes through the cable clamp 3, the cable assembly ring 35 is sleeved on the outside of the cable 5, and the cable assembly ring 35 can fix the cable 5.

[0068] Specifically, refer to Figure 1 as well as Figure 4 As shown, the first main body 33 is provided with a third insertion port, and multiple support pieces 351 are spaced around the third insertion port to form a cable assembly ring 35. Compared with a one-piece cable assembly ring 35, the cable assembly ring 35 formed by multiple spaced support pieces 351 is easier to thread onto the cable 5 and moves more smoothly on the cable 5.

[0069] In some embodiments, the end of the support piece 351 away from the first main body 33 is tilted toward the center of the third plug-in port, so that the diameter of the cable assembly ring 35 gradually decreases from the end near the first main body 33 to the end away from the first main body 33, so that the end of the support piece 351 away from the first main body 33 can better secure the cable 5.

[0070] For example, refer to Figure 3 As shown, the support piece 351 has a first wire-fixing part 352 at the end away from the first main body 33. The first wire-fixing part 352 protrudes towards the center of the cable assembly ring 35, and can further fix the cable 5. For example, the minimum diameter of the first wire-fixing part 352 is smaller than the outer diameter of the cable 5 fitted inside the cable assembly ring 35. After the wire clamp 3 is assembled in place, the first wire-fixing part 352 can be pressed into the outer sheath of the cable 5. When the cable 5 swings to a certain extent, the first wire-fixing part 352 can play a role in fixing the wire and preventing the cable seal 2 from deforming due to the swing of the cable 5.

[0071] In one exemplary embodiment of this disclosure, the wire harness connector further includes a tail clip 4, referenced to... Figure 1 , Figure 3 As shown and Figure 9The schematic view of the tail card 4 is shown. The tail card 4 includes a second body part 41 and a clasp 42. The second body part 41 is provided with a fourth wire insertion port 412 penetrating in the first direction, and the clasp 42 is arranged around the fourth wire insertion port 412 away from the wire end sleeve 1. The cable 5 passes through the tail card 4 through the fourth wire insertion port 412 and the clasp 42. The tail card 4 is sleeved outside the wire fixing clamp 3, and the inner wall of the clasp 42 is attached to the outer wall of the cable assembly ring 35. After the wire seal 2 is pushed into the first wire insertion port 11 through the wire fixing clamp 3, the wire fixing clamp 3 and the wire end sleeve 1 can be fixed through the tail card 4. After the tail card 4 is installed, referring to Figure 3 As shown, the inner wall of the clasp 42 is attached to the outer wall of the cable assembly ring 35, thereby enhancing the wire fixing effect of the cable assembly ring 35 on the cable 5.

[0072] For example, referring to Figure 9 As shown, the clasp 42 is a one-piece structure, and the cable assembly ring 35 is an intermittent structure formed by the support pieces 351 arranged at intervals. Each cable assembly ring 35 is compressible in the radial direction towards the center of the cable assembly ring 35. When the tail card 4 is sleeved outside the wire fixing clamp 3, the rigidity of the clasp 42 is relatively large, and the rigidity of the cable assembly ring 35 is relatively small. The clasp 42 can compress the support pieces 351 in the radial direction, thereby improving the clamping force of the cable assembly ring 35 on the cable 5.

[0073] For example, referring to Figure 9 and Figures 1 to 3 As shown, the diameter of the clasp 42 gradually decreases from the end close to the second body part 41 to the end away from the second body part 41. When the tail card 4 is sleeved outside the wire fixing clamp 3, the clasp 42 can compress the end of each support piece 351 away from the first body part 33, so that the diameter of the cable assembly ring 35 gradually decreases from the end close to the first body part 33 to the end away from the first body part 33. When the wire fixing clamp 3 and the wire end sleeve 1 are assembled in the exemplary embodiment, the gap between each support piece 351 in the free state is relatively large, and it is easier to move on the cable 5. After the wire fixing clamp 3 is installed in place, the tail card 4 is sleeved outside the wire fixing clamp 3, and the clasp 42 can compress the support pieces 351 in the radial direction, so that the gap between the support pieces 351 is reduced, thereby firmly fixing the position of the cable 5 and avoiding the swing of the cable 5.

[0074] Referring to Figure 9 and Figure 3 As shown, the second body part 41 is provided with a surrounding frame 43, which is sleeved outside the wire insertion end 13. The tail card 4 can be fixed with the wire insertion end 13 of the wire end sleeve 1 through the surrounding frame 43, and the wire fixing clamp 3 is clamped between the wire end sleeve 1 and the tail card 4. For example, referring to Figure 7 As shown, the outer wall of the wire insertion end 13 is provided with a first buckle 133; referring to Figure 9 As shown, the inner wall of the surrounding frame 43 is provided with a second buckle 431, and the first buckle 133 and the second buckle 431 are matched to connect the wire fixing clamp 3 and the tail card 4.

[0075] For example, the thinning area 132 can also guide the inner wall of the frame 43, so that the tail card 4 is sleeved on the wire end sheath 1.

[0076] In an exemplary embodiment of the present disclosure, with reference to Figure 3 As shown, the radial projection of the wire fixing clip 3 away from one end of the first main body part 33 is within the range of the clasp ring 42.
