Description

Technical Field

[0001] The utility model relates to the technical field of insulating caps, in particular to a novel insulating cap. Background Art

[0002] The cap is used to seal the end of a cable to prevent water from entering the cable. Most of the existing insulating caps are heat-shrinkable caps. By heating, the cap shrinks and tightly fits over the end of the cable. At the same time, the hot melt adhesive inside the cap melts when heated, increasing the sealing performance between the cap and the cable. However, when removing the cap from the cable, it is necessary to cut the cap with a blade. The blade cutting is likely to scratch the outer surface of the cable, and it is not convenient to use. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a novel insulating cap, aiming to solve the problems mentioned in the above background art.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: The novel insulating cap includes a heat-shrinkable tube. One end of the heat-shrinkable tube is open, and the other end is closed. Grooves are symmetrically arranged on the inner surface of the heat-shrinkable tube. It also includes an easy-to-tear part. The easy-to-tear part includes an end plate. Side plates are symmetrically arranged on the upper surface of the end plate. The two side plates are respectively located inside the grooves. Gripping plates are arranged at the upper ends of the two side plates. A hot melt adhesive layer is arranged on the inner surface of the heat-shrinkable tube. The side plates are located between the heat-shrinkable tube and the hot melt adhesive layer. Fracture seams are respectively arranged on both sides of the groove in the heat-shrinkable tube. The two side surfaces of the fracture seam are connected by fracture points.

[0005] Preferably, the end plate, side plates and gripping plates in the easy-to-tear part are all made of metal.

[0006] Preferably, the joints of the end plate, side plates and gripping plates are all arranged in an arc shape.

[0007] Preferably, an operation ring is arranged on the outer surface of the closed end of the heat-shrinkable tube.

[0008] Preferably, the end plate is circular, and the diameter of the end plate is not greater than the outer diameter of the cable.

[0009] The beneficial effects of the utility model are as follows:

[0010] When removing the cap from the cable, through the arranged end plate, side plates, gripping plates and fracture seams, the heat-shrinkable tube can be torn from the groove, thus realizing the rapid removal of the cap, avoiding scratching the cortex of the cable with a blade, being convenient to operate and having a good use effect.

[0016] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] As Figures 1-4 shown, a new type of insulating cap includes a heat-shrinkable tube 1. One end of the heat-shrinkable tube 1 is open, and the other end is closed. Grooves are symmetrically formed on the inner surface of the heat-shrinkable tube 1. It further includes a tearable part. The tearable part includes an end plate 2. Side plates 3 are symmetrically arranged on the upper surface of the end plate 2. The two side plates 3 are respectively located inside the grooves. Grasping plates 4 are arranged at the upper ends of the two side plates 3. A hot melt adhesive layer 5 is arranged on the inner surface of the heat-shrinkable tube 1. The side plates 3 are located between the heat-shrinkable tube 1 and the hot melt adhesive layer 5. Fracture seams 6 are respectively arranged on both sides of the grooves in the heat-shrinkable tube 1. The two side surfaces of the fracture seam 6 are connected by fracture points.

[0018] When the tearable part is installed inside the heat-shrinkable tube 1, there is a distance between the lower end of the side plate 3 and the bottom of the groove, so that when the heat-shrinkable tube 1 is heated and shrinks, the side plate 3 can move towards the bottom of the groove under the pressure of the heat-shrinkable tube 1 during contraction, so that the tube body of the heat-shrinkable tube 1 can effectively cover the outer surface of the cable.

[0019] The end plate 2 is used to abut against the end of the cable to prevent the end of the cable from piercing the closed end of the heat-shrinkable tube 1.

[0020] In use, first, put the heat-shrinkable tube 1 on the end of the cable, and make the end plate 2 abut against the end of the cable. Then, evenly heat the outer surface of the heat-shrinkable tube 1 through a heating device. After heating, the heat-shrinkable tube 1 shrinks and wraps around the outer surface of the cable. At the same time, the heating will melt the hot-melt adhesive layer 5, which is used to increase the sealing performance between the cable and the heat-shrinkable tube 1. When it is necessary to remove the sealing cap from the cable, first, hold the gripping plate 4 by hand and move the gripping plate 4 towards the direction close to the end of the cable. Through the fracture seam 6 on the heat-shrinkable tube 1, the relatively weak groove position in the heat-shrinkable tube 1 can be torn open. When both grooves are torn open by the gripping plate 4, the heat-shrinkable tube 1 can be removed from the cable. After the groove is torn open, part of the hot-melt adhesive layer 5 adhesively fixed to the side plate 3 will also be detached from the outer surface of the cable, and then the remaining hot-melt adhesive layer 5 can be manually peeled off from the cable.

[0021] Furthermore, the end plate 2, the side plate 3, and the gripping plate 4 in the easily tearable part are all made of metal materials, which can be aluminum or iron. When heating the heat-shrinkable tube 1, the end plate 2, the side plate 3, and the gripping plate 4 will not be damaged, and due to their excellent heat conduction performance, it will not have an obvious adverse effect on the normal melting of the hot-melt adhesive layer 5 inside the heat-shrinkable tube 1.

[0022] Furthermore, the joints of the end plate 2, the side plate 3, and the gripping plate 4 are all set in an arc shape, which can improve the connection stability of the end plate 2, the side plate 3, and the gripping plate 4, and avoid the situation of fracture when tearing the heat-shrinkable tube 1 through the gripping plate 4 and the side plate 3.

[0023] Furthermore, an operation ring 7 is arranged on the outer surface of the closed end of the heat-shrinkable tube 1, which is convenient for holding the heat-shrinkable tube 1 through the operation ring 7.

[0024] Furthermore, the end plate 2 is circular, and the diameter of the end plate 2 is not greater than the outer diameter of the cable. When the heat-shrinkable tube 1 shrinks, the end plate 2 will not hinder the shrinkage of the heat-shrinkable tube 1.

[0025] When removing the sealing cap on the cable, through the provided end plate 2, side plate 3, gripping plate 4, and fracture seam 6, the heat-shrinkable tube 1 can be torn from the groove, thus realizing the rapid removal of the sealing cap, avoiding scratching the cortex of the cable with a blade, with convenient operation and good use effect.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
