Description

Technical Field

[0001] The present invention relates to the field of wire harness detection devices, and in particular to a wire harness continuity detection tool. Background Art

[0002] In modern rail transit systems, cables are key components connecting various devices and systems, and their conductivity is directly related to the safety and stability of train operations. From train power transmission and signal control to various electrical devices within the carriages, all rely on cables to transmit power and signals. A cable conductivity failure can lead to power loss, signal transmission errors, and even safety accidents. Therefore, efficient and accurate continuity testing of wiring harnesses is crucial for ensuring the normal operation of rail transit. It is crucial for promptly detecting and troubleshooting cable faults and ensuring the reliable operation of rail transit systems.

[0003] Currently, traditional rail transit cable continuity testing tooling faces numerous practical challenges. Some tooling uses simple clamping or placement methods to secure the test ports, making them susceptible to displacement during testing due to vibration, impact, and other factors. For example, during simulated train operating conditions, even minor vibrations can loosen the test ports, leading to poor contact and, consequently, testing errors. Regarding testing efficiency, traditional tooling often lacks the ability to flexibly switch test ports, or the switching process is cumbersome and complex. When testing cables of varying specifications or layouts, inspectors often spend considerable time re-adjusting the test equipment, and may even need to replace the entire test equipment. This not only reduces testing efficiency but also increases testing costs, failing to meet the rail transit industry's demand for rapid testing. Furthermore, traditional tooling is mostly monolithic in design and lacks modularity, making it difficult to expand or adapt to actual testing needs. Simply combining or replacing modules to adapt to new cable testing tasks is not an option, limiting the tooling's application.

[0004] In this regard, in order to address this technical problem, the present application proposes a wiring harness continuity detection tool. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a wire harness conductivity detection tool, which improves the detection efficiency, ensures the accuracy of the detection results, avoids detection errors caused by loose ports, provides strong support for the reliable detection of rail transit cables, can quickly switch detection ports, save a lot of time, improve overall detection efficiency, and meet the needs of efficient detection in the rail transit industry.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Reference Figure 1The present invention provides an embodiment of a wiring harness continuity detection tool, comprising a base plate 1, a detection instrument body 2 fixedly connected to the top rear end of the base plate 1, a circuit transmission board 5 fixedly connected to the bottom end of the front side of the detection instrument body 2, a current transmission line 6 fixedly connected to the front side of the circuit transmission board 5, a detection port 8 fixedly connected to the front end of the current transmission line 6, the circuit transmission board 5 and the detection port 8 are connected via the detection port 8, the detection port 8 is connected to a mounting base 7 via a fixed mounting column 11, the mounting base 7 is slidably connected to a limit adjustment plate 9 at the top front end, the limit adjustment plate 9 is fixedly connected to a fixed mounting bracket 17 on the outer wall, a slide 19 is fixedly connected to the middle end of the bottom side of the detection port 8, a slide groove 20 is formed on the top side of the base plate 1, and the outer wall of the slide 19 is slidably connected to the inner wall of the slide groove 20. The adjacent ends of two limit plugs 13 are slidably connected to the inner wall of the preset plug-in slot 10, and one end of the adjustment spring 12 is connected to the inside of the fixed mounting column 11, and the other end is connected to the separated side of the two limit plugs 13. The bottom end of the limit adjustment rod 18 is slidably connected to the inner wall of the preset limit slot 21. Two limit blocks 14 are fixedly connected to the right side of the mounting base 7. Two preset splicing slots 15 are defined on the left side of the mounting base 7. The outer walls of the limit blocks 14 are slidably connected to the inner walls of the preset splicing slots 15. A display screen 3 is provided at the top front end of the detection instrument body 2, and multiple control buttons 4 are located at the bottom of the display screen 3.

[0019] Specifically, when using a harness conductivity detection tool for rail transit cables, the first step before detection is to fix the position of the detection port 8. The detection port 8 is connected to the detection instrument body 2 through the current transmission line 6. The cable conductivity will be transmitted to the detection instrument body 2 through the current transmission line 6 and intuitively displayed on the display screen 3. The operator can judge whether the various interfaces of the cable are conductive based on the data on the display screen 3. The mounting base 7 adopts a modular design. The number of mounting bases 7 can be adjusted at will by engaging the limit plug 14 with the preset splicing groove 15. At the same time, multiple detection ports 8 of different specifications can also be set.

[0020] Reference Figure 2 , the left and right ends of the top side of the mounting base 7 are fixedly connected with fixed mounting columns 11, the middle ends of the left and right sides of the detection port 8 are provided with preset plug-in slots 10, the two fixed mounting columns 11 are slidably connected to the side close to the limit plug-in plate 13, and the top side of the mounting base 7 is provided with an adjustment spring 12; Specifically, when performing the fixing operation, first move the detection port 8 connected to the current transmission line 6 to the top side of the mounting base 7 and place it between the two fixed mounting columns 11. At this time, the detection port 8 can slide left and right between the two mounting bases 7. When the limit plug 13 on the adjacent side of the two mounting bases 7 contacts both sides of the detection port 8, under the action of the adjustment spring 12, the adjustment spring 12 contracts toward the inside of the fixed mounting column 11, allowing the limit plug 13 to slide smoothly. When the adjacent end of the limit plug 13 slides to the preset plug-in slot 10, the adjustment spring 12 rebounds, pushing the limit plug 13 into the preset plug-in slot 10, completing the firm plug-in fixation of the detection port 8.

[0021] Reference Figure 3 , the front side of the limit adjustment plate 9 is fixedly connected to a fixed mounting bracket 17, a rotating shaft is fixedly connected to the interior of the fixed mounting bracket 17, the outer wall of the rotating shaft is rotatably connected to the limit adjustment rod 18, and a preset limit groove 21 is opened at the middle end of the front side of the mounting base 7. The top of the limit adjustment rod 18 is connected to the limit adjustment plate 9 through a spring piece 16; Specifically, if only a single detection port 8 is needed during detection, the operator presses the top of the limit adjustment rod 18, and uses the spring 16 and the lever principle to disengage the bottom end of the limit adjustment rod 18 from the preset limit groove 21. The bottom end of the limit adjustment plate 9 will slide on the mounting base 7, thereby realizing a variety of placement combinations of the limit adjustment plate 9 position. The detection personnel can quickly adjust to the position of the required detection port 8 according to actual needs.

[0022] Working principle: Before conducting a conductivity test on the rail transit cable, the position of the detection port 8 must be fixed first. The detection port 8 is connected to the detection instrument body 2 through the current transmission line 6. The cable conductivity result can be transmitted to the inside of the detection instrument body 2 through the current transmission line 6 and displayed on the display screen 3. The operator can judge whether the various interfaces of the cable are conductive through the data on the display screen 3; the detection port 8 connected to the current transmission line 6 is moved to the top side of the mounting base 7, and then placed between the two fixed mounting columns 11 on the mounting base 7. At this time, the left and right sides of the detection port 8 can slide between the two mounting bases 7. The limit plug-in plate 13 sliding on the adjacent side of the two mounting bases 7 first slides on both sides when contacting the two sides of the detection port 8. Under the elastic action of the adjusting spring 12, the adjusting spring 12 contracts toward the inside of the fixed mounting column 11 to ensure the smooth sliding of the limit plug-in plate 13. When the adjacent end of the two limit plug-ins 13 slides to the preset plug-in slot 10, the limit plug-in plate 13 enters the preset plug-in slot 10 under the rebound action of the adjusting spring 12 to plug and fix the detection port 8.

[0023] The mounting base 7 is modular in design, and the number of mounting bases 7 can be arbitrarily combined by the carding and plugging of the limit plug 14 and the preset splicing groove 15. A plurality of detection ports 8 of different specifications can also be set at the same time. If a single detection port 8 needs to be used during detection, the top end of the limit adjustment rod 18 can be pressed to disengage the bottom end of the limit adjustment rod 18 from the engagement with the preset limit groove 21 under the action of the spring 16 and the lever principle, and the bottom end of the limit adjustment plate 9 slides on the mounting base 7, thereby realizing a variety of placement combinations of the limit adjustment plate 9 position, and the detection personnel can quickly adjust according to the position of the detection port 8 to be used.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
