Description

Technical Field

[0001] This utility model relates to the field of cable termination equipment technology, and in particular to a support bar pull-out cable sealing mechanism. Background Technology

[0002] Cold shrink cable joints are cable connection devices made of elastic materials (such as silicone rubber or ethylene propylene rubber). These joints are manufactured in the factory through pre-expansion and vulcanization molding processes. During on-site installation, the internal support (such as a plastic spiral support strip) is pulled out, allowing it to tightly fit the cable by relying on elastic recoil force, thereby achieving cable insulation and sealing.

[0003] In actual use, the existing cold shrink cable joints have a rubber sleeve that fits tightly against the cable after the support is removed. Although the sealing effect is good, the rubber sleeve that is attached to the cable surface must be peeled off during adjustment and reinstallation. During the peeling process, the rubber sleeve needs to be cut. When cutting and peeling, there is a risk of scratching the cable insulation layer. Therefore, it requires slow and careful operation, which takes a long time and affects the installation efficiency. Utility Model Content

[0004] In view of the problems of easy scratching of cable insulation layer and low efficiency when removing glass after fixing the cable sealing end in the above or existing technology, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a support bar pull-out cable sealing mechanism.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] As a preferred embodiment of the support bar pull-out cable sealing mechanism of this utility model, it includes a cable joint;

[0008] A cold-shrink rubber sleeve is provided on the outside of the cable joint, an auxiliary stripping component is provided inside the cable joint, and a dustproof mechanism is provided at the end of the cold-shrink rubber sleeve.

[0012] As a preferred embodiment of the support strip pull-out cable sealing mechanism of this utility model, the cable joint is provided with a fixed threaded sleeve on the outside, the support strip is spirally coiled inside the cold shrink rubber sleeve, and the end of the support strip is provided with a pull head.

[0013] As a preferred embodiment of the support bar pull-out cable sealing mechanism of this utility model, the outer dustproof cap ring is disposed outside the support pull bar, and the end of the outer dustproof cap ring is provided with an outer ring handle.

[0014] As a preferred embodiment of the support bar pull-out cable sealing mechanism of this utility model, the inner dust cap seals the end of the outer dust cap ring, and the end of the inner dust cap is provided with an inner ring handle.

[0015] As a preferred embodiment of the support strip pull-out cable sealing mechanism of this utility model, the outer side of the rubber strip is arc-shaped, and the end of the rubber strip extends into the support pull-out strip.

[0016] As a preferred embodiment of the support strip pull-out cable sealing mechanism of this utility model, the positioning element includes a positioning ring disposed inside the support strip, and multiple limiting grooves are opened on the outside of the positioning ring, and the rubber strip is stuck in the limiting groove.

[0046] Specifically, the outer side of the rubber strip 41 is arc-shaped, and the end of the rubber strip 41 extends into the support strip 21.

[0047] Furthermore, the outer side of the rubber strip 41 is arc-shaped, and the outer wall of the rubber strip 41 can fit tightly against the inner wall of the cold shrink rubber sleeve 2 without affecting the sealing performance of the cold shrink rubber sleeve 2. The free end of the rubber strip 41 extends into the support strip 21, but the end of the rubber strip 41 does not exceed the range of the spiral support strip 21.

[0048] Specifically, the positioning component 5 includes a positioning ring 51 disposed inside the support strip 21, and multiple limiting grooves 52 are provided on the outside of the positioning ring 51, with the rubber strip 41 being inserted into the limiting grooves 52.

[0049] Furthermore, the positioning component 5 includes a positioning ring 51 mounted inside the support strip 21. Multiple limiting grooves 52 are provided on the outside of the positioning ring 51. The rubber strip 41 is stuck in the limiting groove 52. The cable passes through the inside of the positioning ring 51 to prevent the cable from pressing on the rubber strip 41 when it is inserted.

[0050] Specifically, the positioning ring 51 is provided with multiple positioning platforms 53, the positioning platform 53 is provided with a push plate 55, the push plate 55 is provided with a bonding pad 56 that fits against the support strip 21, and the bonding pad 56 has a friction groove 561 on its surface.

[0051] Furthermore, multiple positioning platforms 53 are fixed to the outside of the positioning ring 51. A movable push plate 55 is provided on the outside of the positioning platform 53. An adhesive pad 56 that fits against the support strip 21 is fixed to the outside of the push plate 55. A friction groove 561 is opened on the surface of the adhesive pad 56.

[0052] Specifically, the positioning table 53 has a telescopic hole 531, the push plate 55 has a telescopic column 551 that extends into the telescopic hole 531, and a spring 54 is installed inside the telescopic hole 531.

A spring 54 is provided in the telescopic hole 531. The spring 54 drives the push plate 55 and the fitting pad 56 to be tightly attached to the inner wall of the support strip 21 by pushing the telescopic column 551.

[0054] When sealing and fixing the cable, first pinch the inner ring handle 311 and pull it upward to pull the inner dust cap 31 off the outer dust cap ring 32 and tear it off. Then insert the cable into the cold shrink rubber sleeve 2 and measure the length. At this time, the cable passes through the middle of the positioning ring. The rubber strip 41 on the outside of the positioning ring is restricted to the outside of the positioning ring and will not be affected by the cable insertion. Then take out the cable, pinch the outer ring handle 321 and tear the outer dust cap ring 32 off the end of the cold shrink rubber sleeve 2. At this time, insert the cable into the cold shrink rubber sleeve 2 and pass it through the cable joint 1 according to the measured length.

[0055] At this point, keep the cable fixed, and then pinch the pull head 211 at the end of the support strip 21. The spiral support strip 21 will be pulled out one turn at a time. When the part of the support strip 21 that contacts the mating pad 56 is pulled out, the positioning ring 51 will be pulled out along with it. If the positioning ring 51 is stuck, it can be removed by hand. At this point, the rubber strip 41 loses the limit of the positioning ring 51 and comes into contact with the cable surface. When the support strip 21 is completely pulled out, the cold shrink rubber sleeve 2 loses the support and shrinks inward. The cold shrink rubber sleeve 2 fits tightly against the cable surface to fix the cable. At the same time, the rubber strip 41 is also pressed inside by the cold shrink rubber sleeve 2.

[0056] When adjusting the installation or disassembling, the cold shrink rubber sleeve 2 fitted on the cable connector 1 can be directly cut with a knife. When cutting the cold shrink rubber sleeve 2 which is tightened on the outer surface of the cable, use a knife to make a longitudinal cut along the protrusion of the rubber strip 41 on the surface of the cold shrink rubber sleeve 2. After the knife cuts the cold shrink rubber sleeve 2, it cuts at the iron core 42 and will not scratch the insulation layer on the surface of the cable.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
