Description

Technical Field

[0001] This utility model relates to the technical field of power cable installation and protection, and in particular to insulating covers. Background Technology

[0002] In the field of power construction, especially in the insulation protection of cable joints, insulating sleeves consisting of two independent shells joined together are widely used. These sleeves are usually equipped with multiple clips or other connecting mechanisms around their four perimeters for fixation.

[0003] However, this traditional split structure has many drawbacks: First, the installation is extremely complicated. Construction workers have to work at heights, and it is inconvenient to carry the equipment while assembling the left and right shells and pressing the multiple buckles around the perimeter. This is not only time-consuming and labor-intensive, but also greatly increases the labor intensity and safety hazards. Second, because the connection points are all around the shell, there are multiple interfaces. These interfaces are very likely to become weak points in waterproof sealing. Moisture may seep in from the connection gaps, endangering the electrical safety of the cable joints. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an insulating cover that is easy to carry and improves installation efficiency.

[0005] The insulating cover of this utility model includes an upper shell and a lower shell, as well as a flexible connecting part and a snap-fit ​​assembly. The upper shell and the lower shell are integrally connected along their first side along their length direction through the flexible connecting part; the upper shell and the lower shell are detachably connected along their second side along their length direction through the snap-fit ​​assembly. The upper shell, the lower shell, and the flexible connecting part are integrally formed. In use, since the upper shell and the lower shell are integrally formed with the flexible connecting part, they are easy to carry. By keeping the two sets of second sides of the upper shell and the lower shell apart, the components that need protection, such as cable connectors, can be placed between the upper shell and the lower shell. The second sides of the upper shell and the lower shell automatically align with the cooperation of the flexible connecting part. The second sides of the upper shell and the lower shell are connected by the snap-fit ​​assembly, which is convenient for installation and improves the sealing performance. The upper shell and the lower shell are integral with the flexible connecting part, making them easy to carry.

[0006] Preferably, the mounting assembly includes a first edge portion, a locking hole, a second edge portion, and locking rod assemblies. The second side of the upper housing is provided with a first edge portion, which has multiple sets of locking holes. The second side of the lower housing is provided with a second edge portion, which has multiple sets of locking rod assemblies. Each locking rod assembly corresponds to one of the locking holes. The cable connector is placed inside the upper and lower housings. Then, with the cooperation of the flexible connection portion, the first and second edges of the upper and lower housings automatically align without manual operation. Afterward, the first and second edges are pressed together, so that each set of locking rod assemblies passes through a set of locking holes, thereby completing the installation of the upper and lower housings.

[0007] Preferably, the locking rod assembly includes a vertical rod and a tapered locking block. The vertical rod is installed on the second edge portion, and the tapered locking block is installed on the end of the vertical rod away from the second edge portion. The cross-sectional area of ​​the locking hole is smaller than the cross-sectional area of ​​the bottom end of the tapered locking block. When the first edge portion and the second edge portion are aligned and pressed together, the tapered locking block is squeezed through the locking hole, and the locking hole undergoes elastic deformation. When the tapered locking block has completely passed through the locking hole, the locking hole recovers its deformation. Since the bottom cross-sectional area of ​​the tapered locking block is larger than the cross-sectional area of ​​the locking hole, it is difficult for the tapered locking block to pass through the locking hole in reverse, thereby achieving the connection between the upper shell and the lower shell.

[0008] Preferably, the locking hole is a tapered hole with a lower cross-sectional area larger than the upper cross-sectional area; the tapered hole facilitates the passage of the tapered locking block and improves installation efficiency.

[0009] Preferably, the vertical rod, the conical locking block, and the second edge portion are integrally formed.

[0010] Preferably, the upper and lower shells are T-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, since the upper shell and lower shell are integrally formed with the flexible connecting part, it is easy to carry. The two sets of second sides of the upper shell and lower shell are separated, and the components that need to be protected, such as cable connectors, are placed between the upper shell and lower shell. The second sides of the upper shell and lower shell are automatically aligned with the cooperation of the flexible connecting part. The second sides of the upper shell and lower shell are connected by the snap-fit ​​assembly, which is convenient for installation and improves the sealing performance. The upper shell and lower shell are integral with the flexible connecting part, making it easy to carry. Attached Figure Description

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the insulating cover of this utility model includes an upper shell 1 and a lower shell 2, and also includes a flexible connecting part 3 and a snap-fit ​​assembly. The upper shell 1 and the lower shell 2 are integrally connected along their first side along their length direction through the flexible connecting part 3; the upper shell 1 and the lower shell 2 are detachably connected along their second side along their length direction through the snap-fit ​​assembly. The upper shell 1, the lower shell 2 and the flexible connecting part 3 are integrally formed.

[0020] The locking assembly includes a first edge portion 4, a locking hole 5, a second edge portion 6, and a locking rod assembly. The second side of the upper housing 1 is provided with a first edge portion 4, and the first edge portion 4 is provided with multiple sets of locking holes 5. The second side of the lower housing 2 is provided with a second edge portion 6, and the second edge portion 6 is provided with multiple sets of locking rod assemblies. The locking rod assemblies correspond one-to-one with the locking holes 5.

[0021] like Figure 3 and Figure 4 As shown, the locking rod assembly includes a vertical rod 7 and a tapered locking block 8. The vertical rod 7 is mounted on the second edge portion 6, and the tapered locking block 8 is mounted on the end of the vertical rod 7 away from the second edge portion 6. The cross-sectional area of ​​the locking hole 5 is smaller than the cross-sectional area of ​​the bottom end of the tapered locking block 8.

[0022] The card hole 5 is a tapered hole with a lower cross-sectional area larger than the upper cross-sectional area;

[0023] The vertical rod 7, the conical locking block 8, and the second edge part 6 are integrally formed;

[0024] The upper shell 1 and the lower shell 2 are T-shaped.

[0025] In this embodiment, the cable connector is placed inside the upper housing 1 and the lower housing 2. Then, with the cooperation of the flexible connecting part 3, the first edge part 4 and the second edge part 6 of the upper housing 1 and the lower housing 2 are automatically aligned without manual operation. Then, the first edge part 4 and the second edge part 6 are pressed together. When the first edge part 4 and the second edge part 6 are aligned and pressed together, the conical block 8 is squeezed through the hole 5. The hole 5 undergoes elastic deformation. When the conical block has passed through the hole 5, the hole 5 returns to its original shape. Since the cross-sectional area of ​​the bottom of the conical block 8 is larger than the cross-sectional area of ​​the hole 5, it is difficult for the conical block 8 to pass through the hole 5 in reverse, thus realizing the connection between the upper housing 1 and the lower housing 2.

[0026] The insulating cover of this utility model is made of silicone material, and all of the components, including the upper shell 1, lower shell 2, flexible connecting part 3, first edge part 4, second edge part 6, vertical rod 7 and conical block 8, are integrally molded by injection molding.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
