Description

Technical Field

[0001] This utility model relates to the field of electrical protection sleeve technology, specifically a warning sleeve for equipment connection points. Background Technology

[0002] As a metal accessory, wire clamps often leave the conductor connection exposed after installation. Although they are usually protected by insulating sleeves, ordinary sleeves have gaps and holes, making it difficult to fully meet the requirements of insulation, waterproofing and corrosion resistance.

[0003] Furthermore, oxidation of conductive contacts increases contact resistance, raises the temperature of the connector or clamp, and can easily lead to burnout. Because of the sheath, these problems are often difficult to detect in a timely manner.

[0004] Therefore, it is necessary to propose a device connection point warning sleeve to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-4As shown, a device connection point warning sleeve includes an elastic sleeve body 3 with a cavity inside. One end of the sleeve body 3 has an inlet 1 communicating with the cavity. An elastic sealing ring 5 is fixedly connected to the inner side of the inlet 1. A sleeve interface 6 communicating with the inlet 1 is opened on one side of the sleeve body 3. Sealing edges 4 extending outward from the sleeve body 3 are provided on both sides of the sleeve interface 6. The two sealing edges 4 are fixedly connected by a connector 2. The sleeve body 3 is made of a reversible thermochromic material. A sealing strip 9 and a limiting strip 10 are respectively provided on the adjacent side of the two sealing edges 4. A limiting groove 8 for limiting the sealing strip 9 is opened in the middle of the limiting strip 10.

[0026] During installation, the sleeve 6 is opened and the sleeve 3 is fitted onto the outside of the clamp. Because the inner diameter of the elastic sealing ring 5 is smaller than the diameter at the clamp interface, it undergoes elastic deformation and fits tightly against the clamp interface, thus sealing the clamp interface. The two sealing edges 4 are pressed to press the sealing strip 9 into the limiting groove 8. Then, the two sealing edges 4 are connected and fixed by the connector 2 to seal the sleeve 6. Under their combined action, the clamp is sealed and protected, preventing rainwater from entering.

[0027] Specifically, the cavity shape is adapted to the shape of the clamp at the connection point of the device to be protected.

[0028] Specifically, sleeve 3 is made of thermochromic silicone. When the clamp at the equipment connection point malfunctions or overheats due to overload, sleeve 3 changes color upon heating, increasing its visibility so that operators can identify and maintain it promptly. When the malfunction or overload is relieved and the temperature drops, the sleeve returns to its original color. In addition, sleeve 3 is made of aging-resistant, corrosion-resistant, high-pressure-resistant, and flame-retardant materials to effectively protect the connection point from the effects of the external environment and extend the service life of the electrical equipment.

[0029] To ensure the stability of the connection, multiple connectors 2 are provided, evenly distributed along the sleeve interface 6. By using multiple connectors 2 to connect and fix the two sealing edges 4, the connection is made more secure, and gaps between the two sealing edges 4 are avoided.

[0030] In some embodiments, the connector 2 includes an umbrella-shaped insert 12, a limiting block 11 is fixedly connected to the umbrella handle of the umbrella-shaped insert 12, and a through hole 13 adapted to the diameter of the umbrella handle is provided on the sealing edge 4.

[0031] To ensure the stability of the connection between the sealing strip 9 and the limiting strip 10, the cross-section of the sealing strip 9 is T-shaped. During connection, pressing the two sealing edges 4 causes the sealing strip 9 to undergo elastic deformation and enter the limiting groove 8, thereby ensuring a stable connection between the sealing strip 9 and the limiting strip 10.

[0032] Specifically, the elastic sealing ring 5 has an opening on one side that communicates with the sleeve interface 6. This opening on one side of the elastic sealing ring 5 allows the interface 1 to be fitted onto the wire clamp.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
