It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0021] Furthermore, 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 the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0022] Example 1 like Figures 1 to 6As shown, the present application discloses a terminal withdrawal detection device for a high-voltage wiring harness, comprising a detection body 1, a wiring harness clamping mechanism 2, a detection mechanism 3, and a terminal clamping mechanism 4. The wiring harness clamping mechanism 2 comprises a driving module 21, a fixed clamping block 22, and a plurality of first clamping assemblies 23. The driving module 21 is mounted on the detection body 1, the fixed clamping block 22 is mounted on the output end of the detection body 1, and moves along the first direction under the drive of the driving module 21. The plurality of first clamping assemblies 23 are all mounted on the output end of the driving module 21, and are located on one side of the fixed clamping block 22 along the second direction. They move along the first direction under the drive of the driving module 21, and are further configured to be able to hold any wiring harness on one side of the fixed clamping block 22 along the second direction against the fixed clamping block 22. The detection mechanism 3 is mounted on the detection body 1. The terminal clamping mechanism 4 is mounted on the detection mechanism 3.

[0023] The present application provides a terminal withdrawal detection device for a high-voltage wiring harness. During detection, multiple wiring harnesses can be fixed to a fixed clamp block 22 in sequence through multiple first clamping components 23. After one wiring harness is detected, another wiring harness can be immediately detected. Compared with related technologies, there is no need to re-clamp the wiring harness, and the detection efficiency is high.

[0024] Optionally, the driving module 21 is configured as a linear module.

[0025] In one embodiment of the present application, see Figures 1 to 6 The first clamping assembly 23 includes a first driver 231 and a first clamping block 232. The first driver 231 is installed at the output end of the driving module 21. The first clamping block 232 is installed at the output end of the first driver 231 and moves along the second direction under the drive of the first driver 231.

[0026] With such arrangement, under the action of the first driver 231 , the wire harness can be clamped between the fixed clamping block 22 and the first clamping block 232 , and the clamping is stable and not easy to loosen.

[0027] Optionally, the first driver 231 is configured as a cylinder.

[0028] In one embodiment of this application, please refer to Figures 1 to 6 The first clamping block 232 includes a first block 2321 and a plurality of first protrusions 2322. The first block 2321 is installed at the output end of the first driver 231. The plurality of first protrusions 2322 are all embedded in the side of the first block 2321 facing the fixed clamping block 22 and are spaced apart along the first direction.

[0029] In this arrangement, multiple first protrusions 2322 protrude from the surface of the first block 2321. Under the action of the multiple first protrusions 2322, the surface roughness of the first block 2321 can be increased, so that the wiring harness can be clamped more stably between the fixed protrusion and the first clamping block 232, and it is not easy to loosen when the wiring harness is tested.

[0030] Optionally, the first bump 2322 is made of polyurethane material.

[0031] This arrangement, where the polyurethane material is a polymer, effectively protects the wiring harness and prevents damage during testing, compared to directly clamping the wiring harness with the first clamping block 2321. Furthermore, by leveraging the polyurethane material's oil resistance, wear resistance, low-temperature resistance, and aging resistance, the wiring harness can be more stably clamped, which helps extend the service life of the first clamping block 232.

[0032] In one embodiment of the present application, see Figures 1 to 6 The wire harness clamping mechanism 2 also includes a plurality of second clamping assemblies 24, which are all installed at the output end of the driving module 21 and are located on the other side of the fixed clamping block 22 along the second direction. They move along the first direction under the drive of the driving module 21, and are also configured to be able to hold any wire harness on the other side of the fixed clamping block 22 along the second direction against the fixed clamping block 22.

[0033] With this arrangement, during testing, multiple first clamping assemblies 23 can sequentially secure multiple wire harnesses to one side of the fixed clamping block 22, while multiple second clamping assemblies 24 can sequentially secure multiple wire harnesses to the other side of the fixed clamping block 22. Compared to using only multiple first clamping assemblies 23, this arrangement allows wire harnesses to be secured from both sides of the fixed clamping block 22, significantly increasing the number of wire harnesses that can be clamped, broadening the device's applicability, and improving testing efficiency.

[0034] In one embodiment of the present application, see Figures 1 to 6 The second clamping assembly 24 includes a second driver 241 and a second clamping block 242. The second driver 241 is installed at the output end of the driving module 21, and the second clamping block 242 is installed at the output end of the second driver 241 and moves along the first direction under the drive of the second driver 241.

[0035] With such arrangement, under the action of the second driver 241 , the wire harness can be clamped between the fixed clamping block 22 and the second clamping block 242 , and the clamping is stable and not easy to loosen.

[0036] In one embodiment of this application, please refer to Figures 1 to 6The second clamping block 242 includes a second block 2421 and a plurality of second protrusions 2422. The second block 2421 is installed at the output end of the second driver 241. The plurality of second protrusions 2422 are all embedded in the side of the second block 2421 facing the fixed clamping block 22 and are spaced apart along the first direction.

[0037] In this arrangement, multiple second protrusions 2422 protrude from the surface of the second block 2421. Under the action of the multiple second protrusions 2422, the surface roughness of the second block 2421 can be increased, so that the wiring harness can be clamped more stably between the fixed protrusion and the second clamping block 242, and it is not easy to loosen when the wiring harness is tested.

[0038] Optionally, the fixed clamp 22 includes a fixed block 221, multiple first fixed protrusions 222 and multiple second fixed protrusions 223. The fixed block 221 is installed at the output end of the first driver 231. The multiple first fixed protrusions 222 are all embedded in the side of the fixed block 221 facing the first block 2321, and are staggered with the multiple first protrusions 2322. The multiple second fixed protrusions 223 are all embedded in the side of the fixed block 221 facing the second block 2421, and are staggered with the multiple second protrusions 2422.

[0039] In this arrangement, multiple first fixing protrusions 222 protrude from the surface of the fixing block 221. The first fixing protrusions 222 increase the surface roughness of the fixing block 221 on the side facing the first block 2321, allowing the wiring harness to be more stably clamped between the fixing protrusions and the first clamping block 232, making it less likely to become loose during testing. Multiple second fixing protrusions 223 protrude from the surface of the fixing block 221. The second fixing protrusions 223 increase the surface roughness of the fixing block 221 on the side facing the second block 2421, allowing the wiring harness to be more stably clamped between the fixing protrusions and the second clamping block 242, making it less likely to become loose during testing. The staggered arrangement of the multiple first fixing protrusions 222 and the multiple first protrusions 2322 allows the wiring harness to be engaged, resulting in a more stable clamping and a better clamping effect than when the multiple first fixing protrusions 222 and the multiple first protrusions 2322 are arranged in a corresponding manner. Since the plurality of second fixing protrusions 223 and the plurality of second protrusions 2422 are staggered, the wiring harness can be engaged. Compared with the corresponding arrangement of the plurality of second fixing protrusions 223 and the plurality of second protrusions 2422, the clamping is more stable and the clamping effect is better.

[0040] Optionally, the second bump 2422 is made of polyurethane material.

[0041] This arrangement, where the polyurethane material is a polymer, effectively protects the wiring harness, preventing damage during testing, compared to directly clamping the wiring harness with the second clamping block 2421. Furthermore, by leveraging the polyurethane material's oil resistance, wear resistance, low-temperature resistance, and aging resistance, it provides a more stable clamping of the wiring harness and helps extend the service life of the second clamping block 242.

[0042] In one embodiment of the present application, see Figures 1 to 6 The wire harness clamping mechanism 2 further includes a plurality of first pre-clamping components 25 , which are all mounted on the fixed clamping block 22 and spaced apart along the third direction.

[0043] With such an arrangement, during detection, multiple wire harnesses can be preliminarily fixed through multiple first pre-clamping components 25. When the first clamping component 23 and the second clamping component 24 are used to clamp the wire harnesses, the wire harnesses can be prevented from shifting, thereby stably clamping the wire harnesses and avoiding repeated adjustment of the wire harnesses to affect the detection efficiency.

[0044] In one embodiment of the present application, see Figures 1 to 6 The first pre-clamping component 25 includes a mounting node 251, two first elastic clamping arms 252 and two second elastic clamping arms 253. The mounting node 251 is installed on the fixed clamping block 22. The two first elastic clamping arms 252 are connected to one end of the mounting node 251 close to the first clamping component 23 and are spaced apart along the third direction. The two second elastic clamping arms 253 are connected to one end of the mounting node 251 close to the second clamping component 24 and are spaced apart along the third direction.

[0045] With such an arrangement, during testing, the wiring harness can be stably fixed to the side of the fixed clamp block 22 facing the first clamp block 232 by the two first elastic clamp arms 252, making it easier for the first clamp block 232 to clamp the wiring harness; and the wiring harness can be stably fixed to the side of the fixed clamp block 22 facing the second clamp block 242 by the two second elastic clamp arms 253, making it easier for the second clamp block 242 to clamp the wiring harness.

[0046] In one embodiment of this application, please refer to Figures 1 to 6 The detection mechanism 3 includes a detection guide rail 31, a detection slider 32 and a push-pull force sensor 33. The detection guide rail 31 is installed on the detection body 1, and the detection slider 32 is installed on the detection guide rail 31. It has a tendency to slide along the first direction under the drive of the terminal clamping mechanism 4. The push-pull force sensor 33 is installed between the detection body 1 and the terminal clamping mechanism 4, and is used to detect the push-pull force exerted on the terminal clamping mechanism 4.

[0047] With such an arrangement, during detection, the terminal clamping mechanism 4 can be prevented from being locked by detecting the guide rail 31 and the slider 32 , thereby ensuring that the push-pull force sensor 33 can normally detect the push-pull force received by the terminal clamping mechanism 4 .

[0048] It should be noted that the first direction mentioned above and below refers to the bidirectional direction of the shortest connection line between the two ends of the driving module 21. Figure 1 The second direction above and below refers to the bidirectional direction of the shortest connection line between the fixed clamping block 22 and the first clamping block 232, specifically as Figure 1 The third direction above and below refers to the bidirectional direction of the shortest connection line between the drive module 21 and the terminal clamping mechanism 4, specifically as Figure 1 The Z axis shown in .

[0049] It should also be noted that in this embodiment, the number of the first clamping components 23 and the number of the second clamping components 24 are both set to two for illustration. Of course, in other embodiments, according to actual application requirements, the first clamping components 23 and the second clamping components 24 can also be set to three, four, five... other numbers, which are not limited here. Let the first clamping block 232 close to the driving module 21 be clamping block number one, let the first clamping block 232 away from the driving module 21 be clamping block number two, let the second clamping block 242 close to the driving module 21 be clamping block number three, and let the second clamping block 242 away from the driving module 21 be clamping block number four.

[0050] The working principle of the terminal withdrawal detection device for high-voltage wire harnesses provided in the present application is as follows: first, four wire harnesses are clamped in sequence at two first pre-clamping assemblies 25. When testing wire harness No. 1, clamp block No. 1 moves along the second direction toward fixed clamp block 22 under the action of first driver 231 to clamp wire harness No. 1 between fixed clamp block 22 and clamp block No. 1. When testing wire harness No. 2, clamp block No. 2 moves along the second direction toward fixed clamp block 22 under the action of first driver 231 to clamp wire harness No. 2 between fixed clamp block 22 and clamp block No. 2. When testing wire harness No. 3, clamp block No. 3 moves along the second direction toward fixed clamp block 22 under the action of second driver 241 to clamp wire harness No. 3 between fixed clamp block 22 and clamp block No. 3. When testing the No. 4 wiring harness, the No. 4 clamping block, under the action of the first driver 231, moves in the second direction toward the fixed clamping block 22, thereby clamping the No. 4 wiring harness between the fixed clamping block 22 and the No. 4 clamping block. After clamping the wiring harness, the driver module 21 drives the fixed clamping block 22, the first clamping assembly 23, and the second clamping assembly 24 to gradually move in the first direction away from the detection mechanism 3, so that the wiring harness tends to separate from the terminal. The push-pull force sensor 33 detects the pulling force applied by the wiring harness to the terminal. If the pulling force exceeds the target threshold and the terminal and wiring harness are not separated, the test is considered to have passed.

[0051] Example 2 This embodiment is basically the same as the first embodiment, the only difference is that: Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the wire harness clamping mechanism 2 also includes a plurality of second pre-clamping components 26, wherein some of the second pre-clamping components 26 are installed on the plurality of first clamping components 23 and are arranged in a one-to-one correspondence with the plurality of first clamping components 23, and another part of the second pre-clamping components 26 are installed on the plurality of second clamping components 24 and are arranged in a one-to-one correspondence with the plurality of second clamping components 24.

[0052] With such an arrangement, during detection, multiple wire harnesses can be preliminarily fixed by multiple second pre-clamping components 26. When the first clamping component 23 and the second clamping component 24 are used to clamp the wire harnesses, the wire harnesses can be prevented from shifting, thereby stably clamping the wire harnesses and avoiding repeated adjustment of the wire harnesses to affect the detection efficiency.

[0053] In one embodiment of the present application, see Figure 1 、 Figure 2 、 Figure 7 and Figure 8The second pre-clamping assembly 26 includes a guide rod 261, a pre-clamping block 262 and an elastic structure 263. The guide rod 261 is passed through the first clamping assembly 23 or the second clamping assembly 24. The pre-clamping block 262 is installed on one end of the guide rod 261 close to the fixed clamping block 22. The elastic structure 263 is sleeved on the guide rod 261 and is configured to drive the pre-clamping block 262 to move toward the fixed clamping block 22.

[0054] With this arrangement, during testing, the wire harness is placed between the pre-clamping block 262 and the fixed clamping block 22. The elastic structure 263 stably clamps the wire harness between the pre-clamping block 262 and the fixed clamping block 22. Compared to the first pre-clamping assembly 25, the distance between the pre-clamping block 262 and the fixed clamping block 22 is adjustable, allowing it to clamp wire harnesses of different sizes, extending its applicability.

[0055] The one or more embodiments of this application are intended to encompass all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this application should be included in the scope of protection of this application.
