Description

Technical Field

[0001] This utility model relates to the field of cable production equipment, specifically a copper wire unwinding distribution board. Background Technology

[0002] In the production process of submarine cables, electric cables and other cables, in order to ensure the safety and quality of the cables, a metal shielding layer is added to the cable structure. The metal shielding layer often uses lead sheath and copper wire slack winding. Among them, copper wire slack winding has obvious advantages in terms of flexibility and resistance to dynamic fatigue.

[0003] In the copper wire winding process, a wire distribution plate with evenly distributed wire holes along the circumference is required. Conventional wire distribution plates adopt a flat plate structure. However, the flat plate structure of the wire distribution plate lacks guidance for the copper wires winding towards the center, which will generate a large change in direction resistance. For copper wires with a diameter ≤1.0mm, it is very easy to cause thinning or breakage, which is not conducive to the high-quality forming of copper wire winding. Among them, without affecting the effect of the metal shielding layer, the smaller the diameter of the copper wire, the smaller the cable diameter can be, the lighter the weight, and the lower the production cost. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a copper wire unwinding guide plate that guides thinner copper wires during the unwinding process to avoid the copper wires from being pulled thin or broken.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a copper wire loose winding splitter plate, including a main body, the main body is ring-shaped, the outer ring of the main body is provided with a splitting plate, the splitting plate is set in a conical shape, the splitting plate has a plurality of splitting holes evenly arranged along the circumference, the splitting holes are set perpendicular to the conical surface of the splitting plate, and the copper wire passes through the splitting holes from the outside of the conical surface of the splitting plate to the inside of the conical surface and loosely winds on the cable.

[0006] Compared with the prior art, the advantages of this utility model are: by setting the conical surface of the equalizing plate and setting the dividing hole perpendicular to the conical surface of the equalizing plate, the loosely wound copper wire can be guided, so that the original single direction change process is transformed into a two-way direction change process, thereby reducing the angle range of a single direction change, thereby reducing the direction change resistance and avoiding the copper wire from being pulled thin or broken.

[0007] As an improvement of this utility model, a nest is provided inside the wire distribution hole, the outer layer of the nest is inserted into the wire distribution hole, and the inner layer of the nest is provided with a through hole. The two ends of the through hole are chamfered. Through this improvement, after long-term use, the copper wire will wear down the wire distribution hole. Therefore, the nest design is added inside the wire distribution hole to protect the wire distribution hole and limit the wear to the nest. After the nest wears down, it can be replaced, thereby ensuring the service life of the distribution board. At the same time, the chamfer design can reduce the directional resistance between the copper wire and the nest, reduce the wear of the nest, and extend the service life of the nest.

[0008] As an improvement of this utility model, the equalization board is designed to be detachably and fixedly connected to the main body. Through this improvement, the equalization board can be replaced. For cables of different specifications and copper wires with different winding numbers, only the equalization board needs to be replaced, instead of replacing the entire distribution board. This improves the applicability of the distribution board, avoids the production of distribution boards of multiple specifications, and reduces the production cost of the distribution board.

[0009] As an improvement of this utility model, a connecting ring is provided at the connection between the main body and the equalizing plate, and an abutting ring is provided on the equalizing plate to abut the connecting ring. The connecting ring and the abutting ring are detachably and fixedly connected by fasteners. Through this improvement, the main body and the equalizing plate are detachably and fixedly connected.

[0010] As an improvement of this utility model, the connecting ring is provided with a threaded hole for fastener thread connection, and the abutting ring is provided with a through hole for fastener to pass through. With this improvement, only one fastener is needed to achieve a fixed connection at one connection point between the connecting ring and the abutting ring, reducing the number of fasteners used.

[0011] As an improvement of this utility model, the end of the through hole away from the threaded hole is provided with a tapered flare, and the fastener is a countersunk screw. Through this improvement, the fixed installation process of the tapered flare and the countersunk screw can utilize the guiding property between the countersunk screw and the tapered flare to keep the countersunk screw and the through hole coaxial. The threaded connection between the countersunk screw and the threaded hole can ensure the coaxiality between the countersunk screw and the threaded hole, thereby correcting the installation alignment between the abutment ring and the connecting ring, improving the installation coaxiality between the abutment ring and the connecting ring, and ensuring the installation quality between the equalizing plate and the main body.

[0012] As an improvement of this utility model, a plurality of combined holes consisting of threaded holes and through holes are provided, and the plurality of combined holes are evenly arrayed along the circumference of the main body. Through this improvement, the connection strength between the dividing plate and the main body is guaranteed.

[0013] As an improvement of this utility model, the contact surfaces of the connecting ring and the abutting ring coincide with the conical surface of the equalizing plate. The connecting ring is located on the inner side of the conical surface, and the abutting ring is located on the outer side of the conical surface. Through this improvement, the design of the contact surfaces of the connecting ring and the abutting ring coinciding with the conical surface of the equalizing plate ensures the uniformity of force on the connecting ring and the abutting ring during the copper wire winding process. At the same time, since the copper wire moves from the outer side to the inner side of the conical surface, using the high-strength main body as the force-bearing base can better guarantee the service life of the dividing plate. Furthermore, during the long-term copper wire guiding process, the abutting ring always moves towards the connecting ring, ensuring the abutting effect between the abutting ring and the connecting ring. This avoids the situation where the connection between the equalizing plate and the main body is easily loosened when the connecting ring is located on the outer side of the conical surface and the abutting ring is located on the inner side of the conical surface.

[0014] As an improvement of this utility model, the inner ring of the main body is provided with a plurality of fixed connection holes, which are evenly arranged in an array along the circumference of the main body. The fixed connection holes are used to fix the main body so that the cable passes through the center of the main body and coincides with the axis of the main body. Through this improvement, the fixed connection of the splitter board is realized during use.

[0015] As an improvement of this utility model, a positioning groove is provided on the inner ring of the main body, which ensures the accuracy and firmness of the wiring board installation. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-3 , Figure 6 As shown, a copper wire loose-wound splitter includes a main body 1, which is annular. The outer ring of the main body 1 is provided with a splitter plate 2, which is conical. The splitter plate 2 has a plurality of splitter holes 2.1 evenly arranged along the circumference. The splitter holes 2.1 are perpendicular to the conical surface of the splitter plate 2. Copper wire 3 passes through the splitter holes 2.1 from the outside of the conical surface of the splitter plate 2 to the inside of the conical surface and is loosely wound on the cable 6.

[0025] like Figure 1 , Figure 3 , Figure 5 As shown, the split hole 2.1 is provided with a nest 4, the outer layer of the nest 4 is inserted into the split hole 2.1, the inner layer of the nest 4 is provided with a through hole 4.1, and the two ends of the through hole 4.1 are provided with chamfers 4.2.

[0026] like Figure 1 , Figure 3 , Figure 4 As shown, a connecting ring 1.1 is provided at the connection between the main body 1 and the equalizing plate 2. The equalizing plate 2 is provided with an abutting ring 2.2 that abuts against the connecting ring 1.1. The connecting ring 1.1 and the abutting ring 2.2 are detachably fixedly connected by countersunk screws 5. The connecting ring 1.1 is provided with a threaded hole 1.2 for threaded connection of the countersunk screw 5. The abutting ring 2.2 is provided with a through hole 2.3 for the countersunk screw 5 to pass through. The end of the through hole 2.3 away from the threaded hole 1.2 is provided with a tapered flared end 2.4. There are multiple combination holes composed of threaded holes 1.2 and through holes 2.3. The multiple combination holes are evenly arrayed along the circumference of the main body 1. The abutting surfaces of the connecting ring 1.1 and the abutting ring 2.2 coincide with the tapered surface of the equalizing plate 2. The connecting ring 1.1 is located on the inner side of the tapered surface, and the abutting ring 2.2 is located on the outer side of the tapered surface.

[0027] like Figure 1 , Figure 2 As shown, the inner ring of the main body 1 is provided with a plurality of fixing connection holes 1.3. The plurality of fixing connection holes 1.3 are evenly arranged in an array along the circumference of the main body 1. The fixing connection holes 1.3 are used to fix the main body 1 so that the cable 6 passes through the center of the main body 1 and coincides with the axis of the main body 1. The inner ring of the main body 1 is provided with a positioning groove 1.4.

[0028] like Figure 6As shown, when using the copper wire winding distributor plate to wind copper wire 3, copper wire 3 first changes direction at one end of the nest 4, changing from a horizontal direction to a direction perpendicular to the conical surface of the distribution plate 2. Then, copper wire 3 changes direction a second time at the other end of the nest 4, changing from a direction perpendicular to the conical surface of the distribution plate 2 to the winding direction of copper wire 3. By changing direction twice, the angle range of a single change is reduced, thereby reducing the resistance to change direction and preventing the copper wire 3 from being thinned or broken. Furthermore, the detachable fixed connection design between the distribution plate 2 and the main body 1 increases the applicability of the copper wire winding distributor plate, reduces the production specifications of the copper wire winding distributor plate, and lowers costs. The design of the nest 4 avoids wear on the distribution plate 2 during long-term guiding of the copper wire 3, ensuring the service life of the distribution plate 2.
