Description

Technical Field

[0001] This utility model relates to the field of electrical equipment protection technology, and in particular to a high temperature warning cable connector sleeve. Background Technology

[0002] Traditional cable joint sleeves mostly use a single sealing structure and lack active warning function for temperature rise. When the cable joint causes local high temperature due to poor contact or overload, it is necessary to rely on manual inspection or external sensor monitoring, which has problems such as response delay, high cost, and easy false alarm.

[0003] In existing technologies, although some connector sleeves incorporate temperature-sensitive materials, they only provide warnings through color changes, which are not sufficiently visible in complex environments. Utility Model Content

[0004] In view of this, the main objective of this utility model is to solve one of the above-mentioned problems.

[0005] This utility model provides a high-temperature warning cable connector sleeve, comprising: a main body, several warning structures, and a color-changing coating; the main body includes a half-shell, a lead-in port, a mating interface, a fixing seat, a sealing ring, and a sealing insulation layer; one end of the half-shell is provided with the lead-in port for inserting and exiting cables, and the other end of the half-shell is provided with the mating interface, both the top and bottom ends of which are provided with the fixing seat, and the mating interface is provided with the sealing ring; the lead-in port is provided with the sealing insulation layer inside; several warning structures are provided on the half-shell, each warning structure including a placement groove, a memory spring, and a warning label; the placement groove is located in the half-shell, and both the memory spring and the warning label are located in the placement groove, with the warning label connected to the half-shell via the memory spring; wherein, the memory spring will elongate under high-temperature conditions and push the warning label out of the placement groove; the color-changing coating is applied to the outer surface of the main body, and the color-changing coating will change color under high-temperature conditions.

[0006] Furthermore, the bottom layer of the color-changing coating is an epoxy resin substrate, and the top layer is a rare earth-doped thermochromic material layer. When in a high-temperature environment, the color of the color-changing coating changes from transparent and colorless to colored.

[0007] Furthermore, the warning structure also includes an anti-drop cover, which is made of shape memory metal and is L-shaped. One end of the anti-drop cover is connected to the half-shell, and the other end of the anti-drop cover covers the warning label. When the anti-drop cover is in a high-temperature environment, it will straighten until it is perpendicular to the outer surface of the half-shell.

[0008] Furthermore, a number of heat dissipation fins are evenly distributed on the outer surface of the semi-shell.

[0009] Furthermore, a water-blocking expansion strip is provided at one end of the sealing insulation layer located at the lead port.

[0010] Furthermore, a sealing gasket is provided at the end of the fixing base away from the lead port.

[0011] The beneficial effects of this utility model are as follows:

[0012] A memory spring-driven warning label provides a mechanical alert, while a color-changing coating that changes color at high temperatures creates a visual warning; this dual mechanism enhances reliability. A sealing ring, a sealing insulation layer, and a water-resistant expansion strip provide multiple layers of protection, adapting to high-temperature expansion and humid environments.

The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in the preferred embodiment of this utility model, a high-temperature warning cable connector sleeve includes: a main body 1, several warning structures 2, and a color-changing coating 3.

[0021] like Figure 2 As shown, the main body 1 includes a half-shell 101, a lead-in port 102, a mating interface 103, a fixing base 104, a sealing ring 105, and a sealing insulation layer 106. One end of the half-shell 101 has the lead-in port 102 for inserting and exiting cables. The other end of the half-shell 101 has the mating interface 103. The fixing base 104 is located at both the top and bottom of the mating interface 103. The sealing ring 105 is located at the mating interface 103. The sealing insulation layer 106 is located inside the lead-in port 102. The split-type half-shell 101 design facilitates installation and maintenance, and provides basic protection by encasing the cable connector. The sealing insulation layer 106 is embedded inside the lead-in port, using elastic sealing to compensate for the gap between the cable and the half-shell 101, isolating moisture and dust.

[0022] Several warning structures 2 are disposed on the half-shell 101. Each warning structure 2 includes a placement groove 201, a memory spring 202, and a warning label 203. The placement groove 201 is disposed in the half-shell 101. The memory spring 202 and the warning label 203 are both disposed in the placement groove 201. The warning label 203 is connected to the half-shell 101 through the memory spring 202. The memory spring 202 will elongate under high temperature conditions and push the warning label 203 out of the placement groove 201. Using the memory spring 202 as a high temperature triggering mechanism can achieve passive triggering, without the need for a power supply or sensor, and has high reliability. The surface of the warning label 203 is coated with fluorescent or reflective material and is exposed after being pushed out by the spring, making it visible at night or from a distance.

[0023] The color-changing coating 3 is applied to the outer surface of the main body 1. The color-changing coating 3 will change color under high temperature environment, making the entire connector sleeve a visual warning that is sufficiently eye-catching.

[0024] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0025] In a preferred embodiment, the bottom layer of the color-changing coating 3 is an epoxy resin substrate, and the top layer is a rare-earth-doped thermochromic material layer. When exposed to a high-temperature environment, the color of the color-changing coating 3 changes from transparent and colorless to colored. The epoxy resin substrate, as the bottom layer, provides high adhesion and weather resistance, protecting the shell from corrosion. The rare-earth-doped thermochromic material layer, as the top layer, changes color at high temperatures, with a noticeable color change and a long visibility distance.

[0026] like Figure 2 , Figure 3 As shown, in a preferred embodiment, the warning structure 2 further includes an anti-drop cover 204, which is made of shape memory metal and is L-shaped. One end of the anti-drop cover 204 is connected to the half-shell 101, and the other end covers the warning label 203. When the anti-drop cover 204 is in a high-temperature environment, it will straighten until it is perpendicular to the outer surface of the half-shell 101. At room temperature, the anti-drop cover 204 covers and protects the warning label, preventing foreign objects from clogging the placement slot 203 and preventing the warning label 203 from sliding out of the placement slot 203 due to gravity, thus preventing false alarms. When the anti-drop cover 204 is at a high temperature, it straightens and opens, forming a secondary warning (such as metallic reflection) and completely releasing the warning label.

[0027] like Figure 2 As shown, in a preferred embodiment, a plurality of heat dissipation fins 107 are evenly distributed on the outer surface of the half-shell 101 to increase the heat dissipation area, accelerate heat dissipation, and reduce the internal temperature.

[0028] like Figure 2As shown, in a preferred embodiment, the sealing insulation layer 106 is provided with a water-blocking expansion strip 108 at one end of the lead wire port 102. The expansion strip 108 expands when exposed to water to fill the gaps, dynamically adapts to the ambient humidity, and prevents moisture from seeping in.

[0029] like Figure 2 As shown, in a preferred embodiment, a sealing gasket 1041 is provided at the end of the fixing seat 104 away from the lead port 102 to compensate for the tolerance of the mating surface and to form multiple protections with the sealing ring 105 and the water-blocking expansion strip 108.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
