Description

Technical Field

[0001] The utility model relates to the field of automobile wire harness sheaths, and particularly relates to a flame-retardant automobile wire harness sheath. Background Technique

[0002] An automobile wire harness sheath is a protective sleeve used for connecting wire harnesses in an automobile. It can integrate multiple wire harnesses or cables in a sleeve, making the wiring neater and more compact, reducing chaos and crossing, and improving the maintainability of the circuit. It can also protect wires, cables or wire harnesses from mechanical damage, abrasion and bending stress, etc., thereby extending the life of the wire harness. It can also provide insulation performance to a certain extent to protect the conductors from external electric fields and electromagnetic fields.

[0003] The applicant found through retrieval that the Chinese patent discloses "a flame-retardant protective sleeve for a new type of automobile waterproof integrated bus wire harness", and its publication number is "CN216697852U". This patent mainly sleeves the protective sleeve on the wire harness gradually through an inner sleeve. When the diameter of the wire harness is large, a thrust will be applied to the four groups of inner sleeves during the sleeving process, causing them to move outward, so as to sleeve the inner sleeve on the wire harness. Then, the elastic bands arranged between the four groups of inner sleeves will contract, so that the four groups of inner sleeves approach each other. At the same time, the elastic band arranged inside the arc-shaped groove applies pressure to the outer wall of the inner sleeve through the inclined groove to make the inner sleeve closely adhere to the surface of the wire harness, so that the protective sleeve is well arranged on wire harnesses of different sizes through the inner sleeve to avoid sliding.

[0004] The above device can achieve the effect of fixing and protecting wire harnesses of different sizes through a series of structural settings. However, in actual use, since the inner sleeve closely adheres to the surface of the wire harness, it will cause the power line to generate high temperature during use, thereby having a certain impact on the power line. And the elastic band is prone to elastic failure after being used for a period of time, which will lead to the problem of insecure fixing of the wire harness. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flame-retardant automobile wire harness sheath to solve the problem that when the above device fixes and protects the wire harness, the inner sleeve closely adheres to the surface of the wire harness, which will cause heat accumulation due to the heat generated by the power line during use and have an impact on the power line.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a flame-retardant automotive wire harness sheath as Figures 1 - 5 shown, including a sheath 1 and a wire harness 4. Installation plates 5 are respectively fixedly connected to both ends of the sheath 1. Working ports 6 are opened on the surfaces of the two installation plates 5. Both working ports 6 communicate with the inside of the sheath 1. Auxiliary components 2 for preventing displacement between the sheath 1 and the wire harness 4 are provided on both installation plates 5. Three fixing components 3 for fixing and protecting wire harnesses 4 of different specifications are provided inside the sheath 1. Through the arrangement of the three fixing components 3, the wire harness 4 can be fixed inside the sheath 1, and the wire harness 4 is suspended inside the sheath 1, so as to solve the problem that heat accumulation occurs during the use of the power cord, resulting in too high a temperature of the wire harness 4 and damaging the power cord. Moreover, through the arrangement of the two auxiliary components 2, the sheath 1 can be fixed on the wire harness 4 to prevent the problem that the wire harness 4 loses protection due to displacement between the wire harness 4 and the sheath 1.

[0025] As Figure 5As shown, the auxiliary component 2 includes a connecting pipe 201. One side of the connecting pipe 201 is fixedly connected to one side of one of the mounting plates 5. The connecting pipe 201 communicates with the inside of the working port 6. The auxiliary component 2 further includes a connecting block 204. The inner wall of the connecting block 204 is threadedly connected to the outer wall of the corresponding connecting pipe 201. The inside of the connecting block 204 communicates with the inside of the connecting pipe 201. One end of the connecting block 204 away from the connecting pipe 201 is fixedly connected with an elastic clamping block 203. The elastic clamping block 203 can fix the wire harness 4 and the sheath 1 to prevent displacement between the sheath 1 and the wire harness 4.

[0026] As Figures 2 - 4 shown, the fixing component 3 includes two fixing plates 301. The opposite sides of the two fixing plates 301 are respectively fixedly connected to the top surface and the bottom surface of the inner wall of the sheath 1. Cavities 304 are opened in the interiors of the two fixing plates 301. The fixing component 3 further includes two clamping plates 302. The outer walls of the two clamping plates 302 are respectively slidably connected to the inner walls of the corresponding cavities 304. Fixing grooves 303 are formed on the surfaces of the two clamping plates 302. The fixing grooves 303 can clamp and fix the wire harness 4. On the two sides of the two clamping plates 302 located inside the corresponding cavities 304, limiting blocks 307 are fixedly connected. The limiting blocks 307 can prevent the clamping plates 302 from falling off. Two sliding grooves 308 are formed on the inner walls of the two clamping plates 302. The fixing component 3 further includes two groups of control rods 305. The number of each group of control rods 305 is two. The bottom ends of the two groups of control rods 305 are respectively fixedly connected to the bottom surfaces of the inner walls of the corresponding cavities 304. Springs 306 are sleeved on the rod walls of the two groups of control rods 305. Through the arrangement of the springs 306, the two clamping plates 302 can clamp and fix wire harnesses 4 of most specifications. The rod walls of the two groups of control rods 305 are respectively slidably connected to the inner walls of the corresponding sliding grooves 308.

[0027] As Figure 1 and Figure 3 shown, the sheath 1 is made of polyvinyl chloride material. Polyvinyl chloride has good flame retardancy and insulation properties, and can provide good protection for the wire harness 4. The shape of the fixing groove 303 is semi-conical, similar to a funnel shape with an inner wall that gradually narrows from wide to narrow.

[0028] Working principle of the utility model: When the device is in use, first insert one end of the already installed wire harness 4 through one of the connecting pipes 201 so that one end of the wire harness 4 enters the interior of the sheath 1, and then continue to extend the wire harness 4 into the interior of the sheath 1. Then, when one end of the wire harness 4 contacts one side of the fixing groove 303, since the fixing groove 303 is semi-conical in shape, as the wire harness 4 continues to enter, the two clamping plates 302 can be pushed to both sides away from the wire harness 4, and during the movement of the clamping plates 302, the springs 306 inside the corresponding cavities 304 are compressed, so that the springs 306 generate a force on the clamping plates 302, thereby enabling the two clamping plates 302 to clamp and fix the wire harness 4;

[0029] After the wire harness 4 is placed inside the sheath 1, then sleeve the two elastic clamping blocks 203 on both ends of the wire harness 4. Since the elastic clamping blocks 203 are made of elastic material, a fixing effect can be achieved for most specifications of the wire harness 4. Then, thread the two connecting blocks 204 on the two elastic clamping blocks 203 onto the connecting pipe 201, thereby achieving the effect of preventing displacement between the sheath 1 and the wire harness 4. The original text highlights the innovative structure and does not elaborate too much on the prior art.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
