Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a cable joint protection device for engineering applications. Background Technology

[0002] After the cable is laid, to make it a continuous line, the various sections must be connected as a whole. These connection points must be protected to prevent leakage at the cable joints or damage from external environmental factors. The main function of cable joint protection is to ensure the smooth flow of the line and guarantee the insulation level at the cable joints, ensuring safe and reliable operation. Existing cable joint protection equipment has poor tensile strength at the cable joints and poor insulation protection for the joints within the cable. This makes the lines susceptible to accidental contact, leading to short circuits and posing safety hazards. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model provides a cable joint protection device for engineering applications. Its purpose is to solve the problems of poor tensile strength at the cable joint, poor insulation protection of various line joints within the cable, and the risk of accidental contact leading to short circuits and safety hazards in existing cable joint protection devices.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

A heat shrink tubing is provided between the two protective shells and the branch block. A sealing gasket is provided between the two protective shells. Two symmetrically arranged limiting components are provided inside the two protective shells. A through hole is opened on the side of the two protective shells that is far apart from each other, and a sealing ring is provided in the through hole.

[0006] Furthermore, the dividing block is provided with several evenly distributed dividing grooves.

[0007] Furthermore, the two protective housings are fixedly connected by bolts.

[0008] Furthermore, the junction box is made of insulating material.

[0009] Furthermore, the limiting component includes a first semicircular clip, a second semicircular clip, and a fastening bolt, wherein the first semicircular clip and the second semicircular clip are fixedly connected by the fastening bolt.

[0010] Furthermore, a number of evenly distributed limiting protrusions are provided on the inner wall of the through hole, and a number of limiting grooves corresponding to the limiting protrusions are provided on the outer side of the sealing ring.

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

[0012] This utility model discloses a cable joint protection device for engineering applications. A branching block is placed at the cable joint, and the branching groove separates the various lines to prevent short circuits. Heat-shrink tubing is used to wrap the cable and branching block, preventing the cable joint from shaking and avoiding short circuits. Sealing rings and gaskets provide waterproofing and dustproofing for the cable joint. A limiting component is used to fix the limiting component to the cable, increasing the tensile strength of the cable joint and preventing malfunctions caused by excessive cable stretching leading to loosening of the cable joint.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, an engineering cable joint protection device includes a branch block 1, which is made of insulating material. Two symmetrically arranged protective shells 2 are provided on the outer side of the branch block 1. A through hole 6 is opened on the side of the two protective shells 2 that is far apart from each other. A sealing ring 7 is provided in the through hole 6. The inner diameter of the sealing ring 7 is smaller than the diameter of the cable 14. The inner diameter of the sealing ring 7 is selected according to the diameter of the cable 14. Several evenly distributed limiting protrusions 12 are provided on the inner wall of the through hole 6. Several limiting grooves 13 corresponding to the limiting protrusions 12 are provided on the outer side of the sealing ring 7. The limiting protrusions 12 and the limiting grooves 13 are engaged to prevent the sealing ring 7 from falling off.

[0025] Heat shrink tubing 3 is provided between the two protective housings 2 and the branch block 1, and sealing gasket 4 is provided between the two protective housings 2. Before connecting the two cables 14, the two protective housings 2 are respectively put on the two cables 14.

[0026] The sealing gasket 4 and heat shrink tubing 3 are fitted onto one of the cables 14, and the two cables 14 are connected together. Several evenly distributed branch grooves 8 are provided on the branch block 1. Each connection line of the cable is placed in the branch groove 8. Then, the heat shrink tubing 3 is placed at the joint of the cable 14. The heat shrink tubing 3 is heated with a hot air gun so that the heat shrink tubing 3 wraps around the joint of the cable 14 and the branch block 1 to prevent the joint of the cable 14 from shaking.

[0027] Two symmetrically arranged limiting components 5 are provided inside the two protective shells 2. The limiting components 5 include a first semicircular clip 9, a second semicircular clip 10 and a fastening bolt 11. The first semicircular clip 9 and the second semicircular clip 10 are fixedly connected by the fastening bolt 11.

[0028] Next, the two limiting components 5 are respectively clamped at both ends of the cable 14 connector. The first semi-circular clip 9 and the second semi-circular clip 10 are fixed with fastening bolts 11, so that the first semi-circular clip 9 and the second semi-circular clip 10 are fixed on the cable 14. The distance between the two limiting components 5 is greater than the total length of the two protective shells 2. When the two ends of the cable 14 are stretched, the two limiting components 5 are clamped between the two protective shells 2. The limiting components 5 are stressed, while the cable 14 connector is not stressed, thereby increasing the tensile strength of the cable 14 connector.

[0029] The two protective housings 2 are fixedly connected by bolts, thus completing the protection of the cable 14 joint. The sealing ring 7 and the sealing gasket 4 serve to prevent dust and water. The limiting component 5 increases the tensile strength of the cable 14 joint, preventing the cable 14 joint from loosening due to excessive stretching of the cable 14, which would lead to failure.

[0030] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
