Detailed Implementation

[0018] This utility model discloses a device for testing the durability of household wire harnesses. The specific implementation of this utility model will be further described below with reference to the preferred embodiment (Example 1) and Figures 1 to 4 in the accompanying drawings.

[0019] See Figures 1 to 4 in the accompanying drawings, which show the household wiring harness durability testing equipment from different perspectives.

[0020] Example 1.

[0021] Preferably, the household wire harness durability testing equipment includes a base plate 100, two upright plates 200, and two elastic plates 300. The two upright plates 200 are symmetrically arranged on both sides of the base plate 100, and there is a gap between the two upright plates 200 (the gap between the two upright plates 200 is exactly equivalent to the width of the base plate 100), wherein:

[0022] Each long side of the film 100 has two transition portions 101, and a through hole 102 is provided between the two transition portions 101. The film 100 and the upright piece 200 are perpendicular to each other. The transition portion 101 is located between the film 100 and the upright piece 200, and the transition portion 101 is integrally formed with both the film 100 and the upright piece 200. This ensures that the included angle between the film 100 and the upright piece 200 is always maintained at 90° (i.e., the film 100 and the upright piece 200 are perpendicular to each other), regardless of whether they are subjected to external pulling force.

[0023] The stand plate 200 has an observation hole 201. The stand plate 200 has a joint 202 at the bottom edge of the observation hole 201. The joint 202 is integrally formed with the stand plate 200. One end of the elastic sheet 300 is fixedly connected to the joint 202 (equivalent to one end of the elastic sheet 300 being close to the observation hole 201; in other words, the distance between one end of the elastic sheet 300 and the observation hole 301 is non-existent or almost non-existent). The other end of the elastic sheet 300 is away from the observation hole 201. Referring to Figure 3 of the attached drawings, by means of the elasticity of the elastic sheet 300 itself, the household wire harness to be tested (not shown in the figure) can be simultaneously wound around the ends of the two elastic sheets 300 for a preset time (the specific number of winding turns and other winding methods are not part of the technical solution claimed in this embodiment). Then, the household wire harness is unwound, and a test household wire harness that can be used for subsequent processes to determine whether there are hidden cracks or other detection items can be obtained.

[0024] The elastic sheet 300 is provided with a rod portion 310 and a winding portion 320 integrally formed with the rod portion 310. The rod portion 310 is fixedly connected to the joint portion 202. The thickness of the winding portion 320 is significantly greater than that of the rod portion 310, which makes it convenient for users to choose the winding position of the household wiring harness to match different test requirements.

[0025] The stand-up piece 200 includes a stand-up piece body 210, which has multiple slots 211 (observation holes 201 are also located in the stand-up piece body 210), and the slots 211 are horizontally symmetrically distributed.

[0026] In this case, the transition portion 101 only contacts a portion of the long side of the film 100; in other words, the transition portion 101 does not completely cover the entire long side of the film 100; that is, the middle portion of the long side of the film 100 corresponds to the through hole 102, the portion of the long side surrounding the middle portion corresponds to the transition portion 101, and the remaining portion of the long side does not contact the transition portion 101 or the through hole 102.

[0027] The film 100 and the stand-up film 200 are preferably made of stainless steel.

[0028] The following describes the overall concept of the household wire harness durability testing equipment disclosed in this embodiment: a stable testing environment is achieved through the integrated structural design of the base plate 100, the upright plate 200, and the elastic plate 300. The upright plates 200 are symmetrically arranged on both sides of the base plate 100, and the two are permanently perpendicular through the transition portion 101, ensuring structural rigidity during the test. The elastic plate 300 adopts a stepped design with a thin-diameter rod portion 310 and a thick-diameter winding portion 320, providing both elastic clamping force and allowing selection of the winding position according to the wire harness specifications. The stainless steel base plate 100 and upright plates 200, combined with horizontally symmetrically distributed slots 211, achieve lightweighting while ensuring equipment durability. The winding portion 320 can also be used to perform winding and releasing operations on the household wire harness, simulating wire harness tension scenarios and providing standardized testing conditions for detecting defects such as hidden cracks. It features structural stability, flexible operation, and adaptability to multiple specification testing needs.

[0029] It is worth mentioning that the specific composition and other technical features of the stainless steel material involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0030] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
