Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to an AB glue-filled cable and a glue-filling mold thereof. Background Art

[0002] In the cable forming process, in order to ensure the stability of the cable forming structure, it is necessary to ensure the fullness of the cable internal filling, and filler strips, filler ropes, filler glue and other materials will be used for filling, and then the cable will be wrapped into a cylindrical shape. However, when using filler glue for filling, because the filler glue is in a fluid state, the traditional filler glue needs a long time to solidify and take shape after filling, which leads to the risk of deformation in the subsequent process of cable wrapping, and it needs to be supervised and corrected for a long time, which greatly increases the difficulty and cost of cable molding. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an AB glue-filled cable and a glue-filling mold thereof, which can enable the filling glue to be quickly solidified and shaped, thereby reducing the supervision and correction time in the subsequent molding process of the cable, so as to reduce the molding difficulty and molding cost of the cable.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: an AB glue-filled cable, comprising a plurality of conductors, wherein the plurality of conductors are twisted and gathered into a cylinder, and the outer side of the cylinder is provided with a polyester tape and a copper-plastic composite tape in sequence from the inside to the outside, and the cylinder is shaped by the polyester tape and the copper-plastic composite tape, and the cylinder also includes a filling strip and a cable-forming glue, wherein a plurality of the filling strips are provided, and the plurality of the filling strips are respectively arranged at the gaps between the plurality of conductors, and the cable-forming glue is used to fill the gaps between the conductors and the filling strips, and the cable-forming glue adopts AB glue.

[0005] Compared with the prior art, the utility model has the following advantages: AB glue is used as the filling glue material. At room temperature, the initial curing time of AB glue is about 5 minutes, while the traditional filling glue needs to be exposed to the air, and the initial curing time is more than half an hour. Even the water-blocking glue with special functions in the cable has an initial curing time of more than 24 hours, thereby greatly shortening the curing time of the filling glue, and will not cause deformation of the filling glue in subsequent wrapping, extrusion and other processes, affecting the molding quality of the cable. Therefore, only short-term supervision and correction are required when the filling of the filling glue is just completed, and no long-term supervision and correction are required, thereby reducing the molding difficulty and molding cost of the cable.

[0006] As an improvement of the utility model, the surface of the conductor is wrapped with an insulating layer. Through the improvement, the conductors are prevented from touching each other, forming insulation, ensuring the safe and stable operation of the conductors, and at the same time protecting the conductors from mechanical damage and chemical corrosion, increasing the mechanical strength of the conductors and extending their service life.

[0007] As an improvement of the utility model, the outer layer of the copper-plastic composite belt is further provided with non-woven fabric and outer sheath from the inside to the outside. Through the improvement, the non-woven fabric has the characteristics of good tensile strength, good air permeability and good elongation, and is non-absorbent, high temperature resistant, and has a round and smooth surface after cabling, so that the cable has higher molding and use quality. The outer sheath is used to enhance the strength of the cable, prevent the cable from being damaged, and ensure the safe use of the cable.

[0008] A glue pouring mold for an AB glue-filled cable is used to form an AB glue-filled cable, comprising a conical converging cavity, one end of which is a wire inlet end for gathering multiple conductors and multiple filling strips, and the other end of which is a wire outlet end for connecting to a twisting cage, and a glue inlet port is provided at the upper end of the wire outlet end for supplying cable glue.

[0009] Compared with the prior art, the utility model has the advantages of: utilizing a twisting cage to twist multiple conductors and multiple filling strips, while AB glue enters into the contraction cavity from the glue inlet and adheres to the surface of the conductor and the filling strip, during the twisting process of the conductor and the filling strip, the AB glue in the gap between the conductor and the filling strip is complemented with each other, after the twisting is completed, it is discharged from the wire outlet end, and after the AB glue is initially solidified, the polyester tape and the copper-plastic composite tape can be wrapped, thereby completing the molding of the conductor, the filling strip and the AB glue.

[0010] As an improvement of the utility model, the glue inlet is connected to a glue collecting chamber at one end away from the convergence chamber, and a glue feeding screw is provided in the glue collecting chamber. Through the improvement, glue A and glue B are merged through the glue collecting chamber, and then the glue feeding screw is rotated to feed the glue, so that glue A and glue B are fully and evenly mixed, thereby ensuring the mixing quality and mixing time of glue AB.

[0011] As an improvement of the utility model, two sides of the glue collecting chamber are respectively connected with a glue barrel A and a glue barrel B.

[0012] As an improvement of the present invention, an electric control valve and a flow meter are provided between the glue collecting chamber and the A glue barrel, and an electric control valve and a flow meter are also provided between the glue collecting chamber and the B glue barrel. Through the improvement, it is convenient to control the mixing ratio and mixing time of A glue and B glue.

[0013] As an improvement of the utility model, the wire feeding end is provided with a glue retaining ring, and the glue retaining ring is used to prevent excess AB glue from leaking from the glue pouring mold. Through the improvement, excess AB glue is prevented from leaking from the glue pouring mold.

[0014] As an improvement of the utility model, the wire outlet end is fixedly connected to a twisting cage, and a rubber gasket is provided at the abutting connection between the wire outlet end and the twisting cage. Through the improvement, because the AB glue is in a liquid state in the glue pouring mold, AB glue will drip during the twisting process of the conductor and the filling strip. Through the design of the rubber gasket, the AB glue can be prevented from dripping into the connection between the wire outlet end and the twisting cage, so as to ensure the stability of the connection.

[0015] As an improvement of the utility model, the wire outlet end is provided with a mounting hole for embedding one end of the cage, and an adjusting bolt is provided on the circumference of the mounting hole. The adjusting bolt is used to fix one end of the cage to the wire outlet end and adjust the coaxiality of the cage and the wire outlet end. Through the improvement, the wire outlet end and the cage are fixed while ensuring the coaxiality of the two. Excess AB glue can also be scraped off through the wire outlet end, and the coaxiality of the scraped surface is guaranteed, thereby ensuring the molding quality of the cable.
