The number of the branch lines is plural, but it is to be noted that before the insulating layer or the like is peeled off, the relative distance and the relative angle between the plural branch lines are the same. However, after the separation, the position of each branch line changes to some extent according to the use requirements.
In order to ensure the stability of the branch line at the relative position of the main line connection part, under the condition of not actually observing, the grounding part with a corresponding structure is arranged to ensure that the grounding part is simultaneously in clamping fit with a plurality of branch lines, and the limit of the branch line is realized by the aid of the grounding part.
Therefore, a plurality of limiting holes are uniformly formed in the circumferential direction of the grounding piece, and the limiting holes are matched with the outer diameter of the corresponding branch lines, so that the grounding piece and the branch lines can be stably connected. In practical application, the limiting holes correspond to the plurality of finger tubes 2 one to one, and the limiting holes are located on the inner sides of the corresponding finger tubes 2, so that the grounding piece is not of a planar structure.

For more detailed description, the grounding part comprises a central block 8 and a plurality of circular rings 6, the inner sides of the circular rings 6 are limiting holes, and the circular rings 6 are connected with the central block 8 through connecting rods 7. The centre piece 8 is located on the web 3 and the ring 6 is located within the vial 2. The connecting rod 7 has a certain bending angle, so that the circular ring 6 is positioned in the finger tube 2, and a through hole for avoiding the pouring opening 14 is formed in the central block 8.
In some embodiments of the multi-functional conveniently-operated cold-shrink multi-fingerstall provided by the invention, please refer to fig. 1, a sealing sleeve 9 is arranged at the end of the vial 2 far away from the main tube 1, and the sealing sleeve 9 is arranged between the inner side surface of the vial 2 and the support bar 5; the gland 9 is used to close the gap between the vial 2 and the branch line.
The cold shrink tube is generally a cold shrink type cable accessory, which is a part of various cable accessories formed by injecting, vulcanizing and molding an elastomer material in a factory, expanding the diameter and lining with a plastic spiral support.
The existing cold shrink tube is insufficient in sealing performance, air or moisture easily permeates into the interior of the cold shrink tube, so that the joint of an internal cable is oxidized and even generates electric leakage, the safety is low, and the practicability is low.
The prefabricated sealing clay cold-shrink sleeve pipe adopts a single cold-shrink sleeve pipe to carry out waterproof sealing on a cable joint, and an ethylene propylene rubber belt and the cold-shrink sleeve pipe are usually adopted to be matched for use, namely, 3-5 layers of ethylene propylene rubber belts are wound at the cable joint, then the cold-shrink sleeve pipe is contracted and held tightly outside the ethylene propylene rubber belt, and the requirements of people on the manufacturing process of the cold-shrink sleeve pipe are higher and higher along with the continuous development of science and technology.
The existing prefabricated sealing cement cold-shrink sleeve has certain defects when being installed and used, the traditional cold-shrink sleeve is often poor in sealing performance due to the fact that external factors influence the cold-shrink sleeve in the using process, and the waterproof performance is poor.
For the reasons, in the invention, the sealing sleeve 9 is arranged on the inner side surface of the end part of the vial 2, the sealing sleeve 9 has certain flexibility, and the sealing sleeve 9 is internally provided with a plurality of holes for liquid flowing, so that the liquid can still flow in the sealing sleeve 9 even under the action of the vial 2 pressing the sealing sleeve 9.
The problem that a gap exists between the inner side face of the finger tube 2 and the branch line is solved by arranging the sealing sleeve 9, and meanwhile, the problem that the fixing glue cannot be injected due to close contact between the finger tube 2 and the branch line is solved.
In some embodiments of the multi-functional cold-contraction multi-finger sleeve convenient to operate, the circulation groove is arranged along the circumferential direction of the inner side surface of the finger tube 2 and is positioned on the outer side of the sealing sleeve 9; a sprue 13 communicated with the circulation groove is formed in the finger pipe 2; the flow groove is used for guiding the fixing glue flowing into the pouring gate 13 into the sealing sleeve 9.
In order to ensure that the fixing glue can flow in the sealing sleeve 9, an annular flow groove is formed in the inner side surface of the vial 2, the fixing glue injected from the gate 13 firstly flows in the flow groove, and the flowing of the fixing glue is not convenient because the gap between the inner side surface of the vial 2 and the branch line at other positions is small and the resistance is large.
With the continuous injection of the fixed glue, the fixed glue in the circulation groove can flow into the sealing sleeve 9, and finally when the fixed glue flows out from one end of the sealing sleeve 9 far away from the main pipe 1, the sealing sleeve 9 can be determined to be completely immersed in the fixed glue.
In some embodiments of the multi-functional easy-to-operate cold-shrink multi-finger sleeve provided by the present invention, referring to fig. 1, a pouring opening 14 is provided on the connecting sheet 3, and the pouring opening 14 is used for injecting insulating filling material into gaps of the plurality of branch lines.
After removing the insulating layer and other materials on the main line, a plurality of branch lines are exposed on the main line, and at this time, the protection structure on the branch lines is smaller, and more importantly, a certain gap exists between adjacent branch lines. After the vial 2 is sleeved on the branch line, a certain insulation effect is achieved, but at the connection position of the branch line and the main line, namely the position where the connecting piece 3 exists.
When the traditional method is adopted, no measures are taken, a certain open space is formed in the inner side surface of the connecting piece 3, if the sealing performance is poor or the main pipe 1 and the connecting piece 3 are damaged, certain impurities and even liquid can be gathered in the space, and finally, the wire is damaged at the position and even safety accidents are caused.
In order to avoid the above problem, after the main pipe 1 and the vials 2 are positioned, an insulating filler is poured into the connecting piece 3 through the pouring opening 14 toward the inside of the main pipe 1, and the positions of the plurality of vials 2 are limited by the insulating filler, while the main pipe 1 and the vials 2 are not affected by the external environment even if they are broken.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
