Description

Technical Field

[0001] This utility model relates to the technical field of wire harness monitoring equipment, specifically a condition monitoring component for wire harnesses. Background Technology

[0002] In the complex operating environment of modern engineering vehicles, wiring harnesses, as an important component of the electrical system, play a crucial role in transmitting power and signals. However, engineering vehicles often face harsh working conditions, such as vibration, humidity changes, temperature fluctuations, and frequent mechanical operations. These factors can easily damage wiring harnesses, necessitating their inspection by a wiring harness monitor. When the monitor and the wiring harness are connected via a data cable adapter, the data cable may be bent at a sharp angle, causing the insulation layer at the bend to gradually break and peel off.

[0003] Existing condition monitoring components often lack effective protective measures for critical data cable connectors, which can lead to corrosion or physical damage at the connection points due to long-term exposure, thus affecting the stability and accuracy of data transmission. Furthermore, while traditional data cables have reinforced this area, they still pose a risk of breakage, and once broken, they cannot be replaced and must be scrapped entirely. Therefore, a condition monitoring component for cable harnesses is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a condition monitoring component for wire harnesses, which has the advantages of convenient installation and disassembly, enhanced protection performance, and extended service life, and solves the problems of easy damage and high maintenance costs of traditional data cable connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a status monitoring component for a wire harness, comprising a monitoring instrument body and a data cable, wherein a protective sleeve is provided on the data cable;

[0006] The data cable includes a connector and a wire. The protective sleeve includes an inner soft sleeve, a top fixing collar, and a bottom fixing collar. The inner soft sleeve is detachably installed on the connector. The inner soft sleeve includes a top plate, a base, and a connecting post. The top fixing collar is movably installed on the top of the inner soft sleeve, and the bottom fixing collar is movably installed on the bottom of the inner soft sleeve. The side of the protective sleeve is provided with a fan-shaped notch that mates with the wire. The protective sleeve is fitted onto the wire through the fan-shaped notch.

[0007] Preferably, the connector is provided with a second flange, and the inner end face of the bottom fixing collar is provided with a second groove that mates with the second flange. The inner soft sleeve is engaged with the second flange through the second groove.

[0008] Preferably, the inner end face of the bottom fixing collar is provided with a third groove that mates with the base, and the bottom fixing collar is rotatably connected to the base by being fitted onto the base through the third groove. The inner end face of the top fixing collar is provided with a first groove that mates with the top plate, and the top fixing collar is rotatably connected to the top plate by being fitted onto the top plate through the first groove.

[0009] Preferably, the side end faces of the top plate and the base are provided with arc-shaped grooves, and the inner end faces of the top fixing collar and the bottom fixing collar are provided with arc-shaped protrusions corresponding to the shape of the arc-shaped grooves.

[0010] Preferably, the top of the connecting column is fixedly connected to the bottom of the top plate, the bottom of the connecting column is fixedly connected to the upper end face of the base, the connecting columns are evenly arranged between the top plate and the base, and a gap groove is formed between adjacent connecting columns.

[0011] Preferably, the inner soft sleeve is made of silicone, and the top fixing collar and the bottom fixing collar are made of ABS engineering plastic.

[0012] Preferably, the top fixing collar and the bottom fixing collar have rounded corners near the fan-shaped notch.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model's protective sleeve adopts a split design, consisting of an inner soft sleeve, top and bottom fixing rings. It can be quickly installed or removed by cooperating with the wire through the fan-shaped notch on the side. When the fan-shaped notch is aligned, the protective sleeve can wrap the wire with elastic deformation. Then, rotating the fixing ring will cause the notch to misalign, forming a closed lock, which effectively prevents accidental fall-off. This structure solves the problems of traditional protective sleeves being non-removable or cumbersome to install, which not only reduces maintenance costs, but also avoids protection failure caused by the protective sleeve loosening, and extends the service life of the data cable in frequent bending scenarios.

[0015] The inner soft sleeve of this invention is tightly engaged with the second flange of the connector through the bottom groove, ensuring that it is always fixed at the connection between the connector and the wire and preventing it from sliding along the wire. The top and bottom fixing rings form a staged resistance with the arc-shaped groove of the inner soft sleeve through the arc-shaped protrusion, limiting its rotation and preventing the protective sleeve from falling off due to accidental overlap of the notch. In addition, the spacer groove design of the connecting post reduces the overall rigidity of the inner soft sleeve, allowing the protective sleeve to bend naturally with the deformation when the wire is bent, avoiding protection failure due to excessive rigidity. These structures work together to solve the pain points of easy displacement and loosening of the protective device, and significantly improve the reliability of protection.

[0025] Please see Figures 1-8 A status monitoring component for a wire harness includes a monitoring instrument body 1 and a data cable 2, with a protective sleeve 3 provided on the data cable 2;

[0026] The data cable 2 includes a connector 201 and a wire 202. The protective sleeve 3 includes an inner soft sleeve 301, a top fixing collar 303 and a bottom fixing collar 302. The inner soft sleeve 301 is detachably installed on the connector 201. The inner soft sleeve 301 includes a top plate 3011, a base 3012 and a connecting post 3013. The top fixing collar 303 is movably installed on the top of the inner soft sleeve 301, and the bottom fixing collar 302 is movably installed on the bottom of the inner soft sleeve 301. The side of the protective sleeve 3 is provided with a fan-shaped notch 304 that mates with the wire 202. The protective sleeve 3 is fitted onto the wire 202 through the fan-shaped notch 304.

[0027] Furthermore, the connector 201 is provided with a second flange 203, and the inner end face of the bottom fixing collar 302 is provided with a second groove 30121 that mates with the second flange 203. The inner soft sleeve 301 is engaged with the second flange 203 through the second groove 30121.

[0028] The inner soft sleeve 301 is secured to the outer end face of the second flange 203 by the second slot 30121, so that it is always located at the connection between the connector 201 and the wire 202, preventing it from sliding along the wire 202 and losing its protective effect at the connection.

[0029] Furthermore, the inner end face of the bottom fixing collar 302 is provided with a third slot 3021 that mates with the base 3012. The bottom fixing collar 302 is sleeved on the base 3012 and rotatably connected to it through the third slot 3021. The inner end face of the top fixing collar 303 is provided with a first slot 3032 that mates with the top plate 3011. The top fixing collar 303 is sleeved on the top plate 3011 and rotatably connected to it through the first slot 3032.

[0030] The rotating connection between the top fixing collar 303 and the bottom fixing collar 302 allows the protective sleeve 3 to be fitted onto or removed from the wire 202 under its own elastic deformation when the fan-shaped notches 304 of the inner soft sleeve 301, the top fixing collar 303, and the bottom fixing collar 302 coincide. After being fitted onto the wire 202, the fan-shaped notches 304 on the top fixing collar 303 and the bottom fixing collar 302 are rotated to be symmetrical with the center of the inner soft sleeve 301, thereby causing the surface protective sleeve 3 to fall off. This detachable structure reduces maintenance costs and extends the service life of the data cable 2. The fan-shaped notch 304 design makes it easy for the wire 202 to be inserted into the protective sleeve 3, improving the convenience of operation.

[0031] Furthermore, the side end faces of the top plate 3011 and the base 3012 are provided with arc-shaped grooves 30111, and the inner end faces of the top fixing collar 303 and the bottom fixing collar 302 are provided with arc-shaped protrusions 3031 corresponding to the shape of the arc-shaped grooves 30111.

[0032] When the top fixing collar 303 and the bottom fixing collar 302 rotate by a certain angle, the arc-shaped protrusion 3031 will be stuck in the arc-shaped groove 30111, increasing the rotational resistance. This prevents the top fixing collar 303 and the bottom fixing collar 302 from rotating during use after installation, causing the fan-shaped notch 304 to overlap and resulting in the protective sleeve 3 falling off and being lost.

[0033] Furthermore, the top of the connecting column 3013 is fixedly connected to the bottom of the top plate 3011, the bottom of the connecting column 3013 is fixedly connected to the upper end face of the base 3012, the connecting columns 3013 are evenly arranged between the top plate 3011 and the base 3012, and a spacer groove 3014 is formed between adjacent connecting columns 3013.

[0034] The design of the spaced connecting columns 3013 reduces the support strength between the top plate 3011 and the base 3012, avoiding excessive strength that would cause the wire 202 to bend directly from the outside of the protective sleeve 3, resulting in the protective sleeve 3 losing its protective effect.

[0035] Furthermore, the inner soft sleeve 301 is made of silicone, and the top fixing collar 303 and the bottom fixing collar 302 are made of ABS engineering plastic.

[0036] The silicone material is soft, effectively protecting the wire 202 while facilitating the installation of the protective sleeve 3. The ABS engineering plastic has good elasticity and weather resistance, allowing it to be pried open and fitted onto the data cable 2. It will not age or become brittle after long-term use, and it has sufficient structural strength to prevent the inner soft sleeve 301 from loosening, thus improving the stability of the device.

[0037] Furthermore, the top retaining collar 303 and the bottom retaining collar 302 are rounded at the points near the fan-shaped notch 304.

[0038] The reduced resistance of the top fixing collar 303 and the bottom fixing collar 302 to the wire 202 when the guide and protective sleeve 3 are in contact further improves the ease of installation.

[0039] In use, the inner soft sleeve 301 is first engaged with the second flange 203 on the connector 201 through the second slot 30121 on the inner end face of its bottom fixing collar 302, so that the inner soft sleeve 301 is located at the connection between the connector 201 and the wire 202. Next, the top fixing collar 303 and the bottom fixing collar 302 are rotated so that the fan-shaped notches 304 of the inner soft sleeve 301, top fixing collar 303, and bottom fixing collar 302 are aligned. The protective sleeve 3 is then fitted onto the wire 202 through the fan-shaped notches 304 using its own elastic deformation. Subsequently, the fan-shaped notches 304 on the top fixing collar 303 and the bottom fixing collar 302 are rotated to be symmetrical with the center of the inner soft sleeve 301 to prevent the protective sleeve 3 from falling off. (The last sentence appears to be incomplete and possibly refers to a separate process.) The side end faces of 3011 and base 3012 are provided with arc-shaped grooves 30111, and the inner end faces of top fixing collar 303 and bottom fixing collar 302 have corresponding arc-shaped protrusions 3031. After being rotated into place, the arc-shaped protrusions 3031 will be stuck in the arc-shaped grooves 30111 to prevent the top fixing collar 303 and bottom fixing collar 302 from rotating during use. Because the connecting posts 3013 are evenly arranged between the top plate 3011 and base 3012 and adjacent connecting posts 3013 have spacing grooves 3014, the wire 202 can be prevented from bending outside the protective sleeve 3. The inner soft sleeve 301 is made of silicone material, which is soft and easy to install. The top fixing collar 303 and bottom fixing collar 302 are made of ABS engineering plastic, which has good elasticity, weather resistance and structural strength.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
