[0002] The cable cold shrinkage compensation component includes a cold shrinkable insulating tube, a protective outer sheath, and a grounding material. Among them, the most important is that the cold shrinkable insulating tube is made of an elastic material and is installed by field cold shrinkage through pre-expansion technology to ensure the sealing and insulating performance of the cable connection part.

However, there will be certain defects when the existing cold shrinkable insulating tube is exposed to the external environment for a long time. Since the cold shrinkable insulating tube is tightened around the cable core wire by the memory effect, but as the external temperature continues to rise and is interfered by various aging factors, the cold shrinkable insulating tube outside the cable core wire is prone to deformation or relaxation of elastic stress, and the cold shrinkable insulating tube will be damaged due to the stress interference of the cable core wire.

The sleeve inner support mechanism 300 is used to enhance the compressive protection of the cold - shrinkable insulating tube 200 and forcibly straighten the cold - shrinkable insulating tube 200. The in - tube expansion components 400 are used to provide an outward expansion platform for effective detection of the cold - shrinkable insulating tube 200. The opening - closing control components 500 cooperate with adjacent two in - tube expansion components 400 to regulate the diameter width of the cold - shrinkable insulating tube 200.

[0025] The outer wall of the cold - shrinkable insulating tube 200 is provided with a notch; The sleeve inner support mechanism 300 includes a compressive top plate 310 arranged in the notch. Two transverse grooves 3101 and two limiting grooves 3102 are arranged inside the compressive top plate 310. A sliding column 320 movably installed in the transverse groove 3101 and an anti - seepage inner pad 330 installed on the sliding column 320, and the anti - seepage inner pad 330 is adapted to penetrate into the limiting groove 3102; The in - tube expansion component 400 includes a sliding - assisting drawer plate 410 pressed against the inner side of the cold - shrinkable insulating tube 200. A groove 4101 is arranged inside the sliding - assisting drawer plate 410.

A second upright post 5104 is arranged in the middle of the force arm 520, and a strengthening tension spring 5103 is connected between the first upright post 5102 and the second upright post 5104.

[0027] Pre - pass the cold - shrinkable insulating tube 200 through the part of the cable main body 100 to be wrapped, and then tighten the cold - shrinkable insulating tube 200 outside the cable main body 100 until the cold - shrinkable insulating tube 200 is completely shrunk and wraps the cable main body 100; In the initial state, the adjusting shaft 3502 is adjusted to rotate forward, and the adjusting shaft 3502 cooperates with the gear 3503 to drive two L-shaped toothed plates 340. As the two L-shaped toothed plates 340 continuously contract, the two anti-seepage inner pads 330 fixed on the two L-shaped toothed plates 340 will finally close inside the two transverse grooves 3101, and the two anti-seepage inner pads 330 can completely seal the two transverse grooves 3101; At this time, the cold-shrinkable insulating tube 200 can be completely sealed and protected by the cold-shrinkable insulating tube 200 and the two anti-seepage inner pads 330; When it is necessary to detect the cable main body 100, use a screwdriver to squeeze the pin 450, and the pressed pin 450 and the clamping member 4501 will extend inward along the inner cavity of the mother tube 4401. The moved clamping member 4501 cooperates with the rack 4402 to prevent the pin 450 from slipping. The pressed rod sleeve 4603, the foot pad 4602 and the diagonal support plate 4601 will turn towards the cable main body 100. Finally, the anti-slip pad 470 and the diagonal support plate 4601 will expand to a certain angle, and finally the anti-slip drawer plate 410 pressed in the reverse direction will quickly expand the cold-shrinkable insulating tube 200, thereby forming an effective detection gap. Embodiment 2:

[0028] Combined with Figures 4 to 8 As shown, on the basis of Embodiment 1, the sleeve inner support mechanism 300 further includes a rectangular cover 350 fixedly installed in the middle of the top surface of the compression-resistant top plate 310, an adjusting shaft 3502 movably installed inside the rectangular cover 350, a gear 3503 installed outside the adjusting shaft 3502, a support plate 3504 provided on the adjusting shaft 3502 and fitting on the top surface of the rectangular cover 350, and a locking bolt 3505 provided in the support plate 3504; A screw sleeve 3501 is fixedly installed on the top of the rectangular cover 350, and the threaded section of the locking bolt 3505 is adapted to penetrate into the screw sleeve 3501.

[0029] Among them, a rectangular cavity is opened inside the rectangular cover 350, and two notches adapted to the two L-shaped toothed plates 340 are opened on the inner wall of the rectangular cavity.

[0030] An L-shaped toothed plate 340 is installed on the top of the sliding column 320, and the number of the L-shaped toothed plates 340 is two, and the two L-shaped toothed plates 340 are adapted to penetrate into the inside of the rectangular cover 350; The gear 3503 is adapted to mesh with the tooth openings of the two L-shaped toothed plates 340; The compression-resistant top plate 310 and the two anti-seepage inner pads 330 are both made of plastic, and an insulating rubber gasket is provided on the side of the anti-seepage inner pad 330 in contact with the transverse groove 3101; The adjusting shaft 3502 is composed of a runner, a vertical shaft rod and a rod sleeve, and the support plate 3504 is installed at the bottom of the rod sleeve; The sliding column 320 is installed on one of the top-mounted sliding drawer plates 410.

[0031] Preferably, vertical holes are formed inside the support plate 3504, and the locking bolt 3505 is adapted to penetrate into the vertical holes, and the threaded section of the locking bolt 3505 is adapted to penetrate into the sleeve 3501; Specifically, first reverse the locking bolt 3505 until the locking bolt 3505 is completely withdrawn from the sleeve 3501, then control the adjusting shaft 3502 to rotate, and the gear 3503 provided on the adjusting shaft 3502 can drive the two L-shaped toothed plates 340. When the two sliding columns 320 and the two anti-seepage inner pads 330 move to the selected positions inside the two transverse grooves 3101, the locking bolt 3505 can be tightened inside the sleeve 3501, thereby locking the adjusting shaft 3502 and the gear 3503. Embodiment 3:

[0032] Combined with Figures 4 to 10 As shown, in the above embodiment, the inner pipe expansion component 400 further includes two guiding members 420, and two concave holes 4102 are formed inside the sliding drawer plate 410, and the two guiding members 420 are respectively installed in the two concave holes 4102. Two cables 430 are connected to the inner ends of the inner pressure increasing member 440, and the two guiding members 420 respectively bear on the bent parts of the two cables 430.

[0033] Preferably, the inner end of the sliding drawer plate 410 has an arc-shaped structure, which is used to reduce the wear of the outer insulating layer of the multi-cable body 100, and at the same time improve the efficiency of the sliding drawer plate 410 moving horizontally along the gap between the cold-shrinkable insulating tube 200 and the cable body 100.

[0034] Two limiting grooves 4103 are formed on the side of the sliding drawer plate 410 facing the cold-shrinkable insulating tube 200, and the two cables 430 are adapted to penetrate into the two limiting grooves 4103; Anti-detachment backing plates 4301 are installed at the ends of the two cables 430 penetrating outside the two limiting grooves 4103.

[0035] A transverse hole is formed in the middle of the inner pressure increasing member 440, and a mother pipe 4401 is arranged in the transverse hole, a rack 4402 installed inside the mother pipe 4401, a pin 450 arranged in the inner cavity of the mother pipe 4401, a clamping member 4501 installed in the groove on the outer wall of the pin 450, and a support rod 4502 installed at the inner end of the pin 450, a foot pad 4602 fixedly installed on the back of the inclined support plate 4601, and a rod sleeve 4603 arranged inside the foot pad 4602; The other end of the support rod 4502 is movably installed in the rod sleeve 4603; The sliding assistance drawer plate 410 and the internal pressure increasing member 440 are both made of silica gel material, and the internal pressure increasing member 440 is fixedly installed inside the port of the groove 4101.

[0036] Preferably, a U-shaped transverse groove is formed on the side of the pin column 450 facing the rack 4402, and the clamping member 4501 is fixed on the inner wall of the U-shaped transverse groove.

[0037] The anti-slip pad 470 is provided with corrugated notches on the side facing the cable main body 100 to increase the frictional resistance.

[0038] Specifically, in the initial state, the anti-slip pad 470 shrinks to the inside of the groove 4101, and the outer end of the anti-slip pad 470 is flush with the port of the groove 4101. At this time, the transverse movement of the tube inner gap expanding assembly 400 along the gap between the cable main body 100 and the cold-shrinkable insulating tube 200 will not be blocked.

[0039] The working principle and usage process of the present invention: When the cable joint is pre-treated and has entered the cold-shrinkable terminal assembly link, this device is used to replace the traditional cold-shrinkable compensation terminal assembly; The cold-shrinkable insulating tube 200 in the initial state is penetrated along a core wire led out by the cable. After the cold-shrinkable insulating tube 200 completely covers the outside of the core wire led out by the cable main body 100, the inner lining inside the cold-shrinkable insulating tube 200 is taken out, and the cold-shrinkable insulating tube 200 will quickly shrink and wrap around the outside of the core wire; Then, the adjusting shaft 3502 is rotated forward. At this time, the two L-shaped toothed plates 340 penetrated into the rectangular cover 350 will be driven to contract, and the sliding column 320 installed at the outer end of the L-shaped toothed plate 340 will drive the anti-seepage inner pad 330 to move horizontally along the inside of the compressive top plate 310 until the two anti-seepage inner pads 330 completely block the two transverse grooves 3101. At this time, the covered core wire can be effectively sealed and protected; When the part of the cable joint wrapped with the cold-shrinkable insulating tube 200 fails due to long-term use or other factors, in order to avoid damaging the cold-shrinkable insulating tube 200, a screwdriver is used to apply extrusion pressure to multiple pin posts 450 in sequence until the pin posts 450 and the clamping parts 4501 move horizontally along the inner cavity of the mother tube 4401. After the clamping parts 4501 move, they will quickly snap into the tooth openings of the rack 4402. As the pin posts 450 continue to move horizontally in cooperation with the support rods 4502, the rod sleeve 4603 will be subjected to continuous extrusion pressure. Finally, the inclined support plate 4601 presses against the insulating layer of the cable with the first shaft rod 460 as the axis, and the reaction force acts on the sliding assist drawer plate 410. Eventually, multiple groups of in-tube gap-expanding assemblies 400 and multiple groups of opening and closing control assemblies 500 arranged in a circumferential uniform distribution will expand the diameter width. The multiple groups of in-tube gap-expanding assemblies 400 with the expanded diameter width can expand the selected part of the cold-shrinkable insulating tube 200 outward. At this time, a large enough gap will appear between the cable body 100 and the bulging part of the cold-shrinkable insulating tube 200, and the core wire part of the cable body 100 will be detected through two transverse grooves 3101.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
