[0002] Automotive electromagnetic shielded wiring harness tubes are tubular components installed inside automobiles to wrap and protect electrical wiring harnesses. Their core function is to block external electromagnetic interference through the shielding layer, while preventing electromagnetic radiation generated by the wiring harness itself from affecting other electronic components, thus ensuring the stability and reliability of signal transmission in the automotive electrical system.

[0003] However, traditional wire harness tubes are mostly integrated structures. When a part is damaged due to wear, aging or external force, the entire wire harness tube needs to be replaced, which not only increases maintenance costs but also leads to low maintenance efficiency. Therefore, an electromagnetic shielded wire harness tube for automobiles is proposed to solve the above problems. Utility Model Content

[0006] The connecting mechanism includes a threaded sleeve fixedly connected to the right end of the fixed tube, a threaded ring fixedly connected to the left end of the connecting tube, a contact ring fixedly connected to the inner wall of the threaded sleeve, a concave ring fixedly connected to the inner wall of the threaded ring, and a fixing component provided on the outer arc surface of the threaded ring.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes a positioning block fixedly connected to the outer arc surface of the threaded ring. The inner wall of the positioning block is elastically connected to a limiting post through a connecting spring. The outer wall of the limiting post passes through and is slidably connected to the inner wall of the positioning block. The outer arc surface of the threaded sleeve is fixedly connected to a fixing block.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the threaded sleeve is threadedly connected to the inner wall of the threaded ring.

[0011] As a further description of the above technical solution:

[0012] The right end of the contact ring is in contact with the left end of the concave ring.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the fixing block is provided with a connecting hole, and the left end of the limiting post is inserted into the inner wall of the connecting hole.

[0015] As a further description of the above technical solution:

[0016] A connecting ring is fixedly connected to the right end of the limiting post.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, through the cooperation between the fixed pipe, the connecting pipe and the connecting mechanism, when a part of the automotive electromagnetic shielding wire harness tube is damaged, simply pull the connecting ring to the right to make the limiting post quickly disengage from the fixed block. Then, unscrew the threaded ring to accurately replace the damaged section, which saves materials compared to the traditional whole replacement.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-2 This utility model provides an embodiment of an automotive electromagnetic shielding wire harness tube, including a fixing tube 1, a connecting tube 2 detachably installed on the right side of the fixing tube 1, both the fixing tube 1 and the connecting tube 2 are automotive electromagnetic shielding wire harness tubes, and a connecting mechanism 3 is provided at the right end of the fixing tube 1; when a part of the automotive electromagnetic shielding wire harness tube is damaged, the damaged part can be disassembled, without replacing the entire automotive electromagnetic shielding wire harness tube.

[0029] Reference Figures 2-4 The connecting mechanism 3 includes a threaded sleeve 301 fixedly connected to the right end of the fixed pipe 1, and a threaded ring 306 fixedly connected to the left end of the connecting pipe 2. The threaded ring 306 and the threaded sleeve 301 facilitate the disassembly and replacement of the fixed pipe 1 and the connecting pipe 2. A contact ring 304 is fixedly connected to the inner wall of the threaded sleeve 301, and a concave ring 303 is fixedly connected to the inner wall of the threaded ring 306. The concave ring 303 can hold a sealing ring, and the contact ring 304 provides a seal. A fixing component 305 is provided on the outer arc surface of the threaded ring 306, which enhances the stability between the fixed pipe 1 and the connecting pipe 2.

[0030] Reference Figures 3-5 The fixing component 305 includes a positioning block 3051 fixedly connected to the outer arc surface of the threaded ring 306. The inner wall of the positioning block 3051 is elastically connected to a limiting post 3053 via a connecting spring 3052. The elasticity of the connecting spring 3052 enables the limiting post 3053 to have the functions of resetting and limiting. The outer wall of the limiting post 3053 is slidably connected to the inner wall of the positioning block 3051. The through-hole setting facilitates manual movement of the limiting post 3053. The outer arc surface of the threaded sleeve 301 is fixedly connected to a fixing block 302, which serves as a connection. The outer wall of the threaded sleeve 301 is threadedly connected to the inner wall of the threaded ring 306. The threaded connection between the two achieves the function of quick connection.

[0031] Reference Figure 2 , Figure 3 and Figure 5The right end of the contact ring 304 contacts the left end of the concave ring 303. When they are in contact, the contact ring 304 can squeeze the sealing ring inside the concave ring 303 to achieve a sealing effect. The outer wall of the fixing block 302 is provided with a connecting hole. The left end of the limiting post 3053 is inserted into the inner wall of the connecting hole. The insertion of the two can prevent the threaded sleeve 301 from rotating. The right end of the limiting post 3053 is fixedly connected with a connecting ring 307. The connecting ring 307 can make multiple sets of limiting posts 3053 move to the right synchronously.

[0032] Working principle: When the electromagnetic shielded wiring harness tube of the car is damaged, the damaged part can be disassembled and replaced separately through the connecting mechanism 3: First, the connecting ring 307 moves to the right. At this time, multiple sets of limiting posts 3053 will move synchronously, so that the inner wall of multiple sets of fixing blocks 302 will disengage. Then, rotate the threaded ring 306 to disengage it from the threaded sleeve 301, and complete the disassembly and replacement of the damaged part without replacing the entire wiring harness tube.

[0033] When it is necessary to install the corresponding fixed pipe 1 and its connecting pipe 2, first place the sealing ring inside the concave ring 303, and then rotate the corresponding threaded sleeve 301 and its threaded ring 306. The contact ring 304 on the inner wall of the threaded sleeve 301 abuts against the concave ring 303 on the inner wall of the threaded ring 306, squeezing the sealing ring inside the concave ring 303 to achieve a seal. At the same time, the limiting post 3053 in the positioning block 3051 on the outer arc surface of the threaded ring 306 is inserted into the connecting hole of the fixed block 302 under the action of the connecting spring 3052, preventing the threaded sleeve 301 from rotating and strengthening the stability of the fixed pipe 1 and the connecting pipe 2.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
