Description

Technical Field

[0001] This utility model relates to the field of electronic equipment protection technology, and more specifically, to a TPE self-healing electronic equipment cable connector protective sleeve. Background Technology

[0002] With the rapid popularization and widespread application of electronic devices, cable connectors, as an important component of electronic equipment, directly affect the normal operation of the equipment due to their reliability and durability. During use, cable connectors are frequently subjected to mechanical stresses such as bending, tension, and torsion, which can easily lead to problems such as breakage, wear, and poor contact, resulting in equipment failure and data transmission interruption. TPE (thermoplastic elastomer) materials are widely used in the field of cable protection due to their excellent elasticity, weather resistance, and processing performance.

[0003] Currently, cable connector protective sleeves on the market mainly include silicone sleeves, PVC sleeves, and nylon protective sleeves. These sleeves suffer from limited protection, susceptibility to aging and cracking, lack of self-repair capabilities, and high replacement costs. Traditional silicone sleeves, while flexible, are easily torn and cannot self-heal; PVC sleeves are durable but lack flexibility, easily breaking under frequent bending; nylon sleeves are strong but expensive, and must be replaced entirely after damage. Furthermore, existing protective sleeves generally lack intelligent sensing and active repair functions, failing to self-repair promptly when minor damage occurs, leading to gradual damage and eventual failure. Therefore, a TPE self-healing electronic device cable connector protective sleeve is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of limited protection capability, easy damage, inability to self-repair, and high replacement cost of existing electronic device cable connector protective sleeves.

[0007] Furthermore, the inner buffer structure includes: a corrugated buffer layer, a flexible pad, shock-absorbing protrusions, venting channels, and an elastic support ring; the corrugated buffer layer is distributed in a ring-shaped corrugation on the outer layer of the TPE self-healing material body, a flexible pad is provided on the inner side of the corrugated buffer layer, shock-absorbing protrusions are distributed on the surface of the corrugated buffer layer, venting channels are provided on the corrugated buffer layer, and the elastic support ring is installed at both ends of the corrugated buffer layer.

[0011] Beneficial effects:

[0012] 1. In this utility model, the TPE self-healing material body adopts advanced technology with built-in microcapsule repair agent. When the material has a micro-crack, the ruptured microcapsule releases the repair agent and reacts with the catalyst to form a polymer that fills the crack, achieving self-repair. The inner buffer structure adopts a corrugated design and shock-absorbing protrusions to effectively absorb and disperse external impact forces. The outer protective shell provides robust external protection. The various layers work together to achieve all-round three-dimensional protection for cable joints, significantly improving the service life and protective effect of the protective sleeve, and greatly reducing the failure rate of cable joints.

[0013] 2. In this utility model, the self-healing trigger mechanism monitors the protective sleeve's status in real time using temperature and pressure sensors. When an abnormality is detected, the heating element and vibration exciter are automatically activated to promote the flow and reaction of the repair agent, thereby improving repair efficiency. The sealing and protection system employs a double-seal design to effectively prevent the intrusion of external contaminants such as moisture and dust. The vent valve ensures internal pressure balance, and the drainage channel promptly removes accumulated water. The installation and fixing mechanism adopts a quick-release design for easy installation and maintenance. The overall system uses a modular structure, resulting in low maintenance costs and fully embodying the concepts of intelligence and practicality. Attached Figure Description

[0032] Working Principle: The TPE self-healing electronic device cable connector protective sleeve is installed at the cable connector, and quick installation is achieved through the mounting and fixing mechanism 6. During normal use, the inner buffer structure 2 effectively disperses and absorbs external mechanical stress, protecting the internal cable connector from damage. When the protective sleeve is impacted or develops a micro-crack, the sensor in the self-healing trigger mechanism 4 monitors stress and temperature changes in real time, and the control chip 403 analyzes the data and determines whether a repair program needs to be initiated. When damage is detected, the heating element 404 heats up to the preset temperature, and at the same time, the vibration exciter 405 generates vibration at a specific frequency, causing the microcapsule repair agent 102 to rupture and release the repair agent. The repair agent reacts with the catalyst particles 103 to generate a polymer that fills the crack, achieving self-repair. The entire repair process is completed within 5-30 minutes, and the strength after repair can reach 80-95% of the original material.
