As used in the specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in the specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a bending-resistant wire according to an embodiment of the present invention, as shown in the drawing, the bending-resistant wire includes a core 101 and a plurality of bundles of wires (specifically, a wire a, a wire b, a wire c, and a wire d) wound on a surface of the core 101, the plurality of bundles of wires wound on the surface of the core 101 form a plurality of repeated and continuous minimum winding units 102 (a dashed-line frame portion in fig. 1), each bundle of wires in the minimum winding units 102 are wound side by side at the same angle, and a distance (denoted by f in fig. 1) between adjacent minimum winding units 102 is 2 to 4 times a width (denoted by e in fig. 1) of a single minimum winding unit 102.
In the embodiment of the present invention, the minimum winding unit 102 is a repeatable minimum unit wound on the surface of the core material 101, and the wires are wound side by side in the minimum winding unit 102 and are all wound at the same angle, thereby forming a regular winding body.
Compared with the prior art, the utility model discloses a core improves the part and lies in: the distance between the adjacent minimum winding units 102 is 2-4 times of the width of a single minimum winding unit 102. In this way, there will be enough bending space between the adjacent minimum winding units 102, and when bending the bending-resistant wire, the actual width of the minimum winding unit 102 will be increased based on the bending space due to the larger bending space between the adjacent minimum winding units 102. In other words, when the bending operation is performed on the bending-resistant wire, the bending-resistant wire has enough bending margin to offset the width increase requirement of the minimum winding unit 102 for the bending operation.
In the bending-resistant wire, the minimum winding units 102 are repeated and continuous, and the distance between every two adjacent minimum winding units 102 is 2-4 times of the width of the single minimum winding unit 102, so that the whole bending-resistant wire has the bending resistance. In general, since the minimum winding unit 102 is formed by winding bundles of wires side by side, and the actual size of each bundle of wires is small, the physical size of the minimum winding units 102 is also small, so that although the interval between the adjacent minimum winding units 102 is 2 to 4 times the width of a single minimum winding unit 102, the interval between the adjacent minimum winding units 102 is also small, while the bend-resistant wire as a whole is very long with respect to the minimum winding unit 102, the resulting bend-resistant wire has a bend space everywhere in practice, this is of great significance for the bend-resistant wire, which means that the bend-resistant wire as a whole has bend-resistant properties virtually everywhere, and no matter which part of the bend-resistant wire is bent, there is a corresponding bending space to buffer the requirement for an increase in the width of the minimum winding unit 102.
Specifically, the spacing between adjacent minimum winding units 102 should not be too small, nor too large. If the spacing between adjacent minimal winding units 102 is too small, it provides less bending space and may not meet the bending resistance requirements. If the distance between the adjacent minimum winding units 102 is too large, the wires connected between the adjacent minimum winding units 102 are arranged in the transverse direction and the distance between the wires arranged in the transverse direction is too long, when the bending operation is performed, the wires connected between the adjacent minimum winding units 102 have a greater risk of wire breakage, and if the wires are broken, the whole anti-bending wire cannot transmit signals, and the signal transmission function is lost. The utility model discloses through the experiment of the applicant numerous times prove, when interval between adjacent minimum winding unit 102 is 2 ~ 4 times of minimum winding unit 102 width, can guarantee to provide great space of buckling, reach the anti performance requirement of buckling, to the wire between adjacent minimum winding unit 102, it is unlikely to toward the too much angle of transverse inclination simultaneously, and length is unlikely to the overlength, can avoid this part wire to take place the problem of broken string when buckling many times.
In a specific application scenario, the distance between the adjacent minimum winding units 102 is 3 times the width of the minimum winding unit 102, in this case, the bending resistance of the whole wire is optimal, and both sufficient bending space can be ensured, and the wire between the adjacent minimum winding units 102 is not easy to break.
Through the embodiment of the utility model provides an anti wire rod of buckling because set up a reasonable interval between adjacent minimum winding unit 102 for anti wire rod of buckling is whole everywhere to have anti bending performance, even buckle many times to a certain position of anti wire rod of buckling, also can not take place the broken string problem, thereby has improved the whole anti bending performance of anti wire rod of buckling, the embodiment of the utility model provides an anti wire rod of buckling specially adapted some often need carry out the product of bending operation, for example to earphone cord, robot connecting wire, data line and so on.
Further, the winding angle of the minimum winding unit 102 and the core material 101 form an included angle of 30-60 degrees. Since the minimum winding unit 102 is formed by winding a plurality of bundles of wires around the core material 101 side by side, the winding angle of the minimum winding unit 102 may also refer to the winding angle of the wires. The winding angle of the minimum winding unit 102 is an angle formed with the core material 101. If the core material 101 is horizontally disposed, when each wire in the minimum winding unit 102 is wound around the core material 101, an included angle (acute angle) between each wire and the horizontal line is an included angle with the core material 101. In the present application, the winding angle of the minimum winding unit 102 should not be too large, and should not be too small. If the winding angle of the minimum winding unit 102 is too large, the wire between the adjacent minimum winding units 102 is close to the core material 101, the wire connecting the adjacent minimum winding units 102 inclines to the horizontal direction, and the bending resistance of the wire is affected, and if the winding angle of the minimum winding unit 102 is too small, the wire of the minimum winding unit 102 inclines to the horizontal direction, and the bending resistance of the wire of the minimum winding unit 102 is affected, so that when the winding angle is set, the bending resistance of the wire of the minimum winding unit 102 and the bending resistance of the wire between the minimum winding units 102 are concerned, in the embodiment of the invention, through experiment of the applicant for countless times, the winding angle is set to form an included angle of 30-60 degrees with the core material 101, and the bending resistance of the wire rod can be guaranteed to be better on the whole, without causing a reduction in the bending resistance of a certain portion.
Further, in the above embodiment, the spacing between the adjacent minimum winding units 102 is defined, which can provide the wire with the bending resistance at these places. However, because when buckling the wire rod, specific position of buckling is indefinite, if the pitch between the adjacent bundle of wires is less, then minimum winding unit 102 will be at first by the wire at both ends begin to loosen the line (because have the space of buckling between the adjacent minimum winding unit 102), and the wire in the middle of minimum winding unit 102 is because the pitch undersize, causes the unable in time pine line of wire in the middle, still is in original structure, and the effort that the bending led to the fact can't cushion, just probably causes the broken string of wire in the middle, so the embodiment of the utility model provides a need optimize minimum winding unit 102's structure. In other words, when bending the wire, each bundle of wires in the minimum winding unit 102 also has a requirement of increasing the width, so that the minimum winding unit 102 itself has a certain bending resistance, and to achieve this effect, the embodiment of the present invention defines the pitch between adjacent bundles of wires, specifically, in the minimum winding unit 102, the pitch between adjacent bundles of wires is 0.1-2 times the diameter of a single bundle of wires, so that the minimum winding unit 102 itself has a bending space. That is, when the wire is bent, the minimum winding unit 102 provides a bending space for the wires due to a certain gap between adjacent bundles of wires, so that the minimum winding unit 102 has certain bending resistance.
On one hand, based on the above description, the pitch between the adjacent bundles of wires is not too small, otherwise, the adjacent bundles of wires cannot be buffered timely and effectively, and the risk of breakage of the middle wire of the minimum winding unit 102 is increased; on the other hand, the pitch between the adjacent bundles of wires should not be too large, otherwise the winding angle of each bundle of wires is too small, which causes the wires to incline towards the core material 101, and also increases the risk of breakage. In the embodiment of the present invention, through numerous experiments by the applicant, the inventive discovery sets the pitch between adjacent wires to be 0.1-2 times of the diameter of a single wire, so that the minimum winding unit 102 has better bending resistance. In a specific application scenario, however, the pitch between the adjacent bundle wires is set to 1 time the diameter of a single bundle wire, which exhibits the best bending resistance.
In the embodiment of the present invention, in the minimum winding unit 102, the diameters of the bundles of wires are the same or are not different from each other, and the diameter of the single bundle of wires refers to the diameter of any bundle of wires, and may also refer to the average value of the diameters of all bundles of wires.
Obviously, the cross section of the wire is usually circular, so the above-mentioned pitch size is also taken as a diameter as a reference, but it is easy to be understood by those skilled in the art that the cross section of the wire may also adopt other deformed structures, such as a polygonal structure, or be configured into other structures according to the needs of the practical application scenario. In the case of the wire cross section adopting these deformed structures, the pitch between the adjacent bundles of wires can obviously be set to be 0.1-2 times the width of a single bundle of wires.
Further, the lead is an enameled wire or a bare lead. Similarly, based on different application scenarios, the conductor may adopt a structure of an enameled wire or a structure of a bare conductor. The enameled wire consists of a conductor and an insulating layer, and is formed by annealing and softening a bare wire, painting for multiple times and baking. The bare conductor is a product only provided with a conductor but not an insulating layer, and specifically can be various metals such as copper, aluminum and the like or a composite metal round single wire. In the embodiment of the utility model provides an in, each bundle of wire adopts the wire of same structure in principle, all adopts the structure of enameled wire for example, perhaps all adopts the structure of bare conductor. If the structure of the bare conductor is adopted, the multiple conductors are mutually communicated and transmit the same signal together. If the structure of the enameled wire is adopted, a plurality of beams of wires are not interfered with each other and respectively transmit different signals. Of course, in some special cases, the wires of each bundle may also be wires of a hybrid structure, i.e., in a multi-bundle wire, in which some bundle or bundles of wires are in an enameled wire structure, and some bundle or bundles are in a bare wire structure.
Further, the multi-bundle conducting wires are wound in multiple layers, and insulating layers are arranged between the multi-bundle conducting wires of adjacent layers.
Specifically, when the multi-bundle wires are wound, only one layer can be wound, and multiple layers can also be wound, and different winding modes have different benefits, for example, when only one layer is wound, the overall wire can be ensured to keep strong bending resistance, but the number of signal paths capable of being transmitted is limited; if twine the multilayer, then can guarantee to transmit multichannel signal simultaneously, nevertheless inevitably can reduce the holistic anti bending performance of wire rod to the number of piles of winding is more, and anti bending performance descends then more, so in the embodiment of the utility model discloses the wire of twining too many numbers of piles is not recommended, twines 3 layers at most generally, twines 2 layers preferably to guarantee to have sufficient anti bending performance. When winding a plurality of layers of wires, an insulating layer may be provided between the bundles of wires in adjacent layers so that the bundles of wires between different layers will not interfere with each other. Specifically, after winding a layer of the multi-bundle conductor, an insulating layer, such as an insulating glue, may be coated on the surface of the layer of the multi-bundle conductor. And then, continuing to wind the new multi-bundle wires on the insulating layer, wherein the winding manner of the second layer is the same as that of the first layer, and the finally obtained winding structure can be completely the same or slightly different according to the requirement, for example, the winding angles can be different, the spacing between the adjacent minimum winding units 102 can be different from the multiple of the width of the single minimum winding unit 102, and the winding intercept can be different. In addition, the type of wire wrapped may also vary. However, in any winding structure, the winding manner is the same, that is, "a plurality of repeated and continuous minimum winding units 102 are formed, each bundle of wires in the minimum winding units 102 are wound side by side at the same angle, and the distance between adjacent minimum winding units 102 is 2-4 times the width of a single minimum winding unit 102".
Further, the conductor is provided with 4 bundles, and the 4 bundles of conductors are preferably bare conductors, such as conductor a, conductor b, conductor c and conductor d in fig. 1, and the 4 bundles of bare conductors will transmit signals together. However, obviously, in different application scenarios, the number of the arranged wires can be adjusted according to actual needs, for example, 2 bundles, 3 bundles, 4 bundles, 5 bundles, 6 bundles, etc. can be specifically arranged, but the arrangement and winding manner are the same no matter how many bundles of wires are adopted, so that the wire has sufficient bending resistance as a whole. Even, the wires can be arranged into 1 bundle, only 1 bundle of wires is arranged in one minimum winding unit 102, and the distance between the adjacent minimum winding units 102 is actually the pitch between the adjacent bundles of wires, so that the finally manufactured wire still has better bending resistance.
Further, the core material 101 is a conductive core material or a nonconductive core material. The core material 101 may be a conductive core material or a non-conductive core material depending on the application.
In addition, the core material 101 may be a core material having a tensile property, so that when the bending-resistant wire material is stretched, since the bending space between the adjacent minimum winding units 102 is relatively large, the bending space is actually a stretching space, and the core material 101 located at the middle portion also has a tensile property, the actual width of the minimum winding unit 102 is finally increased based on the stretching space.
It should be noted that fig. 1 is a schematic structural diagram that is drawn for convenience of illustration only, and in an actual product, the diameter of each wire is very small, so in an actual product, the width of the minimum winding unit 102 and the distance between adjacent minimum winding units 102 are very small, so that the wire between adjacent minimum winding units 102 does not incline too much toward the core material 101, and can still maintain a preferred winding angle.
The embodiment of the utility model provides a still provide a method for processing anti kink wire rod, as shown in fig. 2, it includes the step:
s201, controlling the core material to move continuously;
in a specific application scenario, the core material is controlled to be in a continuous moving state, so that the conducting wire can be continuously wound on the surface of the core material in the moving process. Specifically, the core material should move in the same direction, facilitating continuous processing.
Preferably, before the step S201, the method further includes:
a plurality of bundles of wires are wound around a reel in advance.
Namely, when processing is carried out, a plurality of bundles of conducting wires are prepared, and the plurality of bundles of conducting wires are wound on a winding drum in advance so as to facilitate processing.
Accordingly, the controlling the continuous movement of the core material includes:
the core material is controlled to pass through the winding drum and move towards a preset direction.
The winding drum for winding the plurality of wires is a hollow structure, and the middle part of the winding drum can be penetrated by the core material and moves towards a preset direction, namely moves towards the same direction.
S202, pulling out the wound multi-bundle conducting wires, and winding the multi-bundle conducting wires on a core material which continuously moves side by side;
specifically, the wound multi-bundle conducting wire can be led out from one end of the winding drum, specifically, one end of the winding drum faces to the moving direction of the core material, then the multi-bundle conducting wire is continuously pulled out along a preset angle, and the controller is wound on the continuously moving core material, so that the purpose of continuously processing the anti-bending wire is achieved.
S203, forming a plurality of repeated and continuous minimum winding units on the bundles of conducting wires wound on the surface of the core material by controlling the moving speed and/or the winding speed of the core material; each bundle of wires in the minimum winding unit are wound side by side according to the same angle, and the distance between every two adjacent minimum winding units is 2-4 times of the width of the single minimum winding unit;
in order to make the distance between the adjacent minimum winding units 2-4 times the width of a single minimum winding unit, the distance between the adjacent minimum winding units can be controlled based on two control modes, one is to control the moving speed of the core material, for example, to control the moving speed of the core material to be increased, because the winding speed is not changed, the distance between the minimum winding units is increased, and the moving speed of the core material is controlled to be reduced, and because the winding speed is not changed, the distance between the minimum winding units is reduced. One is to control the winding speed, for example, to decrease the winding speed, and to increase the winding speed, since the core material moving speed is not changed, the pitch between the minimum winding units is decreased, and to increase the pitch between the minimum winding units, since the core material moving speed is not changed.
The aforesaid is based on single one kind control mode to realize the control to the interval between the adjacent minimum winding unit, the embodiment of the utility model provides a can adopt two kinds of control modes to realize the control to above-mentioned interval simultaneously equally, the effect that its final reaches also makes the interval between the adjacent minimum winding unit be single 2 ~ 4 times of minimum winding unit width.
And S204, winding the wound anti-bending wire.
After a plurality of bundles of wires are wound on the surface of the core material, a winding device can be arranged at one end of the core material in the moving direction to wind the anti-bending wire material manufactured after winding so as to continuously process the anti-bending wire material.
