Description

Technical Field

[0001] This utility model relates to an insulating sleeve for terminals, and more particularly to an insulating sleeve, belonging to the technical field of electrical components. Background Technology

[0002] Terminals generally refer to wiring terminals. Their main function is to transmit electrical signals or conduct electricity. In mechanical equipment, terminals can be used for motor wiring, sensor signal processing, control circuit connection, etc. To ensure the proper operation of terminals, insulating sleeves are usually used to protect the exposed parts of the terminals, preventing them from being affected by external wear, breakage or electrical faults, thereby ensuring the reliability and safety of electrical connections.

[0003] Most existing insulating sheaths have weak waterproof performance, and are prone to leakage and electrical leakage in harsh environments such as dampness and rain, which poses certain risks to the use of wires and cables. In particular, when used in high-salt environments such as seaside and coastal areas, their anti-corrosion performance is more easily affected, so they must be maintained and replaced frequently. At the same time, the installation process of insulating sheaths is relatively complicated, and it is particularly inconvenient when replacement is needed.

[0004] Therefore, it is urgent to improve the insulating sheath to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an insulating sleeve for terminals.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: an insulating sleeve for terminals, comprising an insulating protective sleeve, the insulating protective sleeve being composed of a first outer shell and a second outer shell, the insulating protective sleeve being symmetrically provided with a cable waterproof structure on its upper and lower sides, the cable waterproof structure including a cable waterproof base disposed on the first outer shell, a cable waterproof cover mounted on the second outer shell on one side of the cable waterproof base, the cable waterproof base and the cable waterproof cover being respectively connected to the first outer shell and the second outer shell by a plurality of first bolts, the cable waterproof base being connected to the cable waterproof cover by a plurality of second bolts, the cable waterproof base being fixedly connected with a plurality of first support columns and second support columns, a plurality of fixing blocks being provided between the first support columns and the second support columns, and cable holes being opened on the surface of the fixing blocks.

[0007] Preferably, the outer walls of the first and second support columns are provided with sliding grooves, and the two sides of the fixing block are provided with sliders suitable for sliding connection with the sliding grooves.

[0008] Preferably, the insulating protective sleeve is symmetrically fixedly installed with multiple fixing structures, each fixing structure consisting of multiple hook bases, multiple elastic hooks, and multiple hook sleeves. The hook bases are fixedly installed on both sides of the second outer shell, the elastic hooks are fixedly connected to one side of the hook bases, and the hook sleeves are fixedly connected to both sides of the first outer shell.

[0009] Preferably, the hook sleeve has holes on its surface suitable for the elastic hook, and the position and direction of the hook sleeve correspond to those of the hook base.

[0010] Preferably, the first outer shell has sealing grooves on both sides of its wall thickness, and the second outer shell has sealing strips that are adapted to the sealing grooves fixedly installed on both sides of its wall thickness.

[0011] Preferably, the inner wall of the first outer shell is fixedly installed with a plurality of limiting strips that fit against the inner wall of the second outer shell.

[0012] Preferably, the area of ​​the cable hole on the fixing block on both sides of the second support column is larger than that of the other cable holes.

[0013] Preferably, anti-slip strips are symmetrically fixedly installed on the surfaces of the first outer shell and the second outer shell.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. With the cable waterproofing mechanism in place, when the insulation sheath is put into use, the cable can be inserted through the cable holes on the surface of multiple fixing blocks. After the cable is inserted, the cable hole is completely covered by the cable. At the same time, the fixing blocks can fit into the cable waterproofing base through the sliding groove. The cable waterproofing base is connected to the cable waterproofing cover by bolts to complete the seal and form the cable waterproofing mechanism. The cable waterproofing mechanism can also be connected to the insulation sheath by bolts. After the connection is complete, it can effectively prevent water penetration, thus protecting the cable and terminals from moisture and damage.

[0016] 2. Multiple fixing structures are installed on both sides of the insulating sleeve. The hook base and hook sleeve are respectively installed on the first and second outer shells. The elastic hook on the hook base can be squeezed inward to deform the two sides of the hook slightly inward so that it can be put into the hook sleeve and fit perfectly, so that the first and second outer shells fit together. The fixing structure makes it easier and faster to replace the insulating protective sleeve. When the equipment fails, it can significantly reduce downtime, thereby improving production efficiency and reducing production losses. At the same time, the maintenance process is simpler, thereby reducing maintenance time and labor costs. In addition, the reduction in downtime also reduces the indirect costs caused by downtime.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figures 1-6As shown in the figure, the terminal insulating sleeve provided in this embodiment includes an insulating protective sleeve 1, which is composed of a first outer shell 2 and a second outer shell 3. The insulating protective sleeve 1 is symmetrically provided with a cable waterproof structure 4. The cable waterproof structure 4 includes a cable waterproof base 6 set on the first outer shell 2. A cable waterproof cover 7 installed on the second outer shell 3 is provided on one side of the cable waterproof base 6. The cable waterproof base 6 and the cable waterproof cover 7 are both connected to the first outer shell 2 and the second outer shell 3 respectively by multiple first bolts 5. The cable waterproof base 6 is connected to the cable waterproof cover 7 by multiple second bolts 8. Multiple first support columns 9 and second support columns 10 are fixedly connected to the cable waterproof base 6. Multiple fixing blocks 11 are provided between the first support columns 9 and the second support columns 10. The outer walls of the first support columns 9 and the second support columns 10 are provided with sliding grooves 13. The fixing blocks 11 are provided with sliders 14 on both sides for sliding connection with the sliding grooves 13. Cable holes 12 are provided on the surface of the fixing blocks 11. The surface of the cable waterproof structure 4 can be sealed by connecting the cable waterproof base 6 and the cable waterproof cover 7. After connecting the insulating protective sleeve 1, its waterproof performance is greatly improved.

[0027] The insulating protective sleeve 1 is symmetrically fixed with multiple fixing structures 15. Each fixing structure 15 consists of multiple hook bases 16, multiple elastic hooks 17, and multiple hook sleeves 18. The hook bases 16 are fixedly installed on both sides of the second outer shell 3. The elastic hooks 17 are fixedly connected to one side of the hook bases 16, and the hook sleeves 18 are fixedly connected to both sides of the first outer shell 2. Holes 23 for the elastic hooks 17 are formed on the surface of the hook sleeves 18. The position and direction of the hook sleeves 18 correspond to those of the hook bases 16. The elastic hooks 17 on the hook bases 16 can be pressed inwards, causing the sides of the hooks to deform slightly inwards, allowing them to fit snugly into the hook sleeves 18, thus fitting the first outer shell 2 and the second outer shell 3 together. The fixing structure 15 allows for easier and faster replacement of the insulating protective sleeve 1. The first outer shell 2 and the second outer shell 3 are provided with sealing grooves 19 on both sides of the wall thickness. Sealing strips 20 that are compatible with the sealing grooves 19 are fixedly installed on both sides of the wall thickness of the second outer shell 3, so that the connection between the first outer shell 2 and the second outer shell 3 is tighter. Multiple limiting strips 21 that fit against the inner wall of the second outer shell 3 are fixedly installed on the inner wall of the first outer shell 2, so that the cable is limited when it enters the insulating sleeve 1. The cable type classification is clear inside the insulating protective sleeve. The cable hole 12 on the fixing block 11 on both sides of the second support column 10 has a larger area than the other cable holes 12, so that there is still enough space when a larger cable is needed without restricting the cable specification. Anti-slip strips 22 are symmetrically fixedly installed on the upper and lower surfaces of the first outer shell 2 and the second outer shell 3, which can increase the contact area and increase the friction to prevent slippage.

[0028] like Figures 1-6As shown, the principle of the terminal insulating sleeve provided in this embodiment is as follows: By squeezing the elastic hooks 17 in the fixing structure 15 on both sides of the insulating protective sleeve 1 so that they fit perfectly into the hook sleeve 18, the first outer shell 2 and the second outer shell 3 can be quickly separated and installed. This structure is simple in design and easy to use. When a fault or damage occurs, it can be quickly and easily replaced, and normal operation can be quickly restored. This avoids production losses caused by long-term downtime and greatly reduces the difficulty and time of maintenance personnel. At the same time, the cable waterproof structure 4 at both ends of the insulating protective sleeve 1 can achieve a sealing effect, effectively preventing moisture from penetrating into the interior of the insulating protective sleeve 1, thereby avoiding moisture corrosion and damage to the internal components. This can significantly extend the service life, reduce faults and damage caused by moisture, and ensure that the equipment can still work normally in humid or watery environments, thereby improving the reliability of the equipment.
