Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically a waterproof electrical seal for a cable joint. Background Technology

[0002] A cable joint waterproof seal is a waterproof device used to protect cable joints. Its main function is to prevent moisture from entering the joint, ensuring the normal operation of the joint and extending its service life. The device usually consists of sealing materials and fasteners, and can provide multiple layers of protection.

[0003] Existing technology, such as patent publication number CN219960096U, discloses a waterproof cable connector, including a connector body, a gripping claw, a sealing element, a clamping nut, and an end nut. The clamping nut and end nut are screwed to both ends of the connector body, respectively. The gripping claw is coaxially disposed at one end of the connector body and located inside the clamping nut. The sealing element is disposed inside the gripping claw. It also includes a diameter-matching sealing cylinder, which is detachably connected to the inner hole of the sealing element, and a sealing connection is established between the diameter-matching sealing cylinder and the sealing element. By setting diameter-matching sealing cylinders with different inner hole sizes, wiring of cables of different diameters can be achieved, eliminating the need for classified management of waterproof cable connectors. While the aforementioned sealing seal reduces the requirements for connector transportation and processing, the length of existing sealing seals is usually fixed. When encapsulating long cables, it cannot meet the encapsulation requirements matching the cable. Furthermore, the waterproof performance of existing sealing seals is greatly reduced during frequent friction with the cable. Therefore, a waterproof sealing seal for cable connectors is needed. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof electrical seal for cable joints to solve the problems of poor size compatibility and low waterproof performance of existing electrical seals.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof electrical seal for a cable connector includes two shrink tubing, one end of which is fixedly fitted with a shrink threaded tube. A shortening tube is threaded onto the shrink threaded tube, and an extension mechanism is provided on the shrink threaded tube. The extension mechanism includes two connecting tubes and an extension tube. The two connecting tubes are respectively fixedly installed at one end of the two shrink threaded tubes, and a first retaining ring is fixedly installed inside the connecting tube. Two second retaining rings are fixedly installed side by side inside the extension tube.

[0007] Preferably, the front end of the retractable hose is composed of several inclined triangular pads, and the inner diameters of the retractable threaded tube and the connecting tube are the same.

[0008] Preferably, the extension tube is composed of several folded short tubes, and the inner diameter of the extension tube is larger than the inner diameter of the connecting tube.

[0009] Preferably, a glue storage mechanism is provided between the connecting pipe and the extension pipe. The glue storage mechanism includes two glue storage tubes and sealant. A third buckle is fixedly installed at both ends of the two glue storage tubes, and a glue injection tube is fixedly installed on the glue storage tube. A sealing cap is threaded on the glue injection tube.

[0010] Preferably, the first and second buckles are rotatably connected to the third buckle in a buckling manner, and the inner diameters of the first, second, and third buckles are the same.

[0011] Preferably, the glue storage tube is rotatably connected to the connecting tube and the extension tube respectively, and the sealant is located inside the glue storage tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This waterproof electric seal is used for cable joints. When the rotating shortening tube moves inward on the shrinking threaded tube, it will support several triangular soft pads to initially clamp the cable. The inner diameter of the shrinking threaded tube and the connecting tube are the same to ensure the flatness of the inner wall of the electric seal, so that the cable can be inserted into the electric seal. The extension tube is stretched or contracted according to the length of the cable joint to ensure that the cable joint is always inside the electric seal, thus improving the adaptability of the electric seal.

[0014] 2) This waterproof electrical seal for cable joints is made by unscrewing the sealing cap and injecting sealant into the storage tube through the injection tube. At the same time, the storage tube is rotated to fill the space between the storage tube and the cable with sealant. The sealing cap is then used to allow the sealant to solidify, thus completing the sealing of the cable joint. Thanks to the tight connection effect of the sealant, the waterproof performance of the electrical seal is greatly improved. Attached Figure Description

[0022] Combination Figure 1 and Figure 2 The cable connector waterproof electrical seal includes two shrink tubing 1, one end of which is fixedly installed with a shrink threaded tube 2, and a shrinking tube 3 is threaded onto the shrink threaded tube 2. An extension mechanism 4 is provided on the shrink threaded tube 2. The extension mechanism 4 includes two connecting tubes 401 and an extension tube 403. The two connecting tubes 401 are respectively fixedly installed at one end of the two shrink threaded tubes 2, and a first retaining ring 402 is fixedly installed inside the connecting tube 401. Two second retaining rings 404 are fixedly installed side by side inside the extension tube 403.

[0023] The front end of the retractable hose 1 is composed of several inclined triangular soft pads. When the retractable hose 3 is rotated and moves inward on the retractable threaded tube 2, it will support several triangular soft pads to initially clamp the cable. The inner diameters of the retractable threaded tube 2 and the connecting tube 401 are the same to ensure the flatness of the inner wall of the electric seal, so that the cable can be inserted into the electric seal. The extension tube 403 is composed of several folded short tubes, and the inner diameter of the extension tube 403 is larger than the inner diameter of the connecting tube 401. The extension tube 403 is stretched or contracted according to the length of the cable joint to ensure that the cable joint is always inside the electric seal.

[0024] Example 2

[0025] See Figure 3 and Figure 4 A glue storage mechanism 5 is provided between the connecting pipe 401 and the extension pipe 403. The glue storage mechanism 5 includes two glue storage tubes 501 and sealant 505. A third buckle 502 is fixedly installed at both ends of the two glue storage tubes 501, and a glue injection tube 503 is fixedly installed on the glue storage tube 501. A sealing cap 504 is threaded on the glue injection tube 503.

[0026] The first retaining ring 402 and the second retaining ring 404 are both rotatably connected to the third retaining ring 502 in a snap-fit ​​manner. The inner diameters of the first retaining ring 402, the second retaining ring 404 and the third retaining ring 502 are the same. The glue storage tube 501 is rotatably connected to the connecting tube 401 and the extension tube 403 respectively. The sealant 505 is located inside the glue storage tube 501. By unscrewing the sealing cap 504, the sealant 505 is further injected into the glue storage tube 501 through the glue injection tube 503. At the same time, the glue storage tube 501 is rotated to fill the space between the glue storage tube 501 and the cable with the sealant 505. The sealing cap 504 is then used to allow the sealant 505 to solidify, thus completing the sealing of the cable joint. Thanks to the tight connection effect of the sealant 505, the waterproof performance of the electrical seal is greatly improved.

[0027] In actual operation, when the rotating shortening tube 3 moves inward on the shrinking threaded tube 2, it will support several triangular soft pads to initially clamp the cable. The inner diameters of the shrinking threaded tube 2 and the connecting tube 401 are the same to ensure the flatness of the inner wall of the electric seal, so that the cable can be inserted into the electric seal. The extension tube 403 is stretched or contracted according to the length of the cable joint to ensure that the cable joint is always inside the electric seal.

[0028] By unscrewing the sealing cap 504, the sealant 505 is further injected into the reservoir tube 501 through the injection tube 503. At the same time, the reservoir tube 501 is rotated to fill the space between the reservoir tube 501 and the cable with the sealant 505. The sealing cap 504 is then used to allow the sealant 505 to solidify, thus completing the sealing of the cable joint. Thanks to the tight connection effect of the sealant 505, the waterproof performance of the electrical seal is greatly improved.
