Technical Field

[0001] The present application relates to the technical field of wires and cables, and in particular to a bend-resistant wire. Background Art

[0002] In modern society, humans are inseparable from electricity. In terms of work and life, electricity brings a lot of convenience to people, such as computers, TVs, refrigerators, etc. To make electricity available everywhere, wires for transmitting current are indispensable. Since wires need to be applied in various harsh environments, the requirements for wires are getting higher and higher, such as being acid-resistant, heat-resistant or fire-proof, which also makes the quality of current wires better and better; traditional wires generally consist of a conductive wire core and an insulating layer wrapped around the outer surface of the conductive wire core.

[0003] Regarding the above related technologies, the applicant believes that the current wires have low bend resistance. During the transportation and laying of wires, the wires are easily bent, resulting in phenomena such as twisting, displacement or even breakage of the inner core inside the wires, and still need to be improved. Utility Model Content

[0004] In order to improve the bend resistance of wires, the present application provides a bend-resistant wire.

The anti-bending structure includes a deformable support plate and a fixing plate. The support plate is arc-shaped. One end of the support plate forms a mounting plate, and the other end forms a mounting groove for inserting the mounting plate. A plurality of arc-shaped support plates are connected to each other and wrapped around the wire inner core. The mounting plate of one support plate is inserted into the mounting groove of the adjacent support plate; the fixing plate is fixed between the support plate and the wire inner core.

[0007] By adopting the above technical solutions, the fixing plate supports the support plate outside the wire inner core, so that there is a deformation space and a distance between the support plate and the wire inner core, thereby reducing the direct impact on the wire inner core; the setting of the mounting plate and the mounting groove realizes the stable connection between multiple support plates, and at the same time, the arc-shaped structure of the support plate cooperates with the shape of the wire inner core to achieve circumferential protection outside the wire inner core, improving the bend resistance of the wire.

[0008] Preferably, the fixing plates are oppositely arranged on the same support plate; the anti-bending structure further includes a plurality of reinforcing plates fixed between the opposite fixing plates.

[0009] By adopting the above technical solutions, the opposite fixing plates play a more stable supporting role for the support plate; the reinforcing plates between the opposite fixing plates further improve the structural stability.

[0010] Preferably, several of the reinforcing plates are sequentially connected between the fixing plates to form several triangles.

[0011] By adopting the above technical solution, several triangles are formed by sequentially connecting the reinforcing plates, and a stable supporting effect can be obtained.

[0012] Preferably, an arc-shaped connecting plate is fixed between the fixing plates on the adjacent supporting plates.

[0013] By adopting the above technical solution, the connecting plate is arranged in an arc shape to match the shapes of the inner core and the protective layer of the wire, and the structure is more reasonably arranged and used to improve the overall strength of the structure.

[0014] Preferably, a bend-resistant plate with a shape matching that of the supporting plate is fixed on the outer side of the supporting plate.

[0015] By adopting the above technical solution, on the one hand, the bend-resistant plate cooperates with the supporting plate to improve the anti-deformation and anti-bending ability, and on the other hand, it increases the thickness of the supporting plate, improves the structural strength, and has a better buffering effect when the wire is bent or impacted.

[0016] Preferably, a plurality of deformation grooves are formed at intervals on the side wall of the bend-resistant plate; the cross-section of the deformation groove is an isosceles trapezoid with an opening towards the outside of the bend-resistant plate.

[0017] By adopting the above technical solution, the deformation grooves provide a bending deformation space for the bend-resistant plate, thereby preventing the bend-resistant plate from tearing; the cross-section of the deformation groove is an isosceles trapezoid with an opening towards the outside of the bend-resistant plate, increasing the deformation space to improve the fold resistance.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] The fixing plate supports the supporting plate outside the inner core of the wire, so that there is a deformation space and a distance between the supporting plate and the inner core of the wire, thereby reducing the direct impact on the inner core of the wire; the arrangement of the mounting plate and the mounting groove realizes the stable connection between multiple supporting plates, and at the same time, the supporting plate is in an arc-shaped structure to match the shape of the inner core of the wire to achieve the surrounding protection outside the inner core of the wire, improving the fold resistance of the wire;

[0020] The opposite fixing plates play a more stable supporting role for the supporting plate; the reinforcing plates between the opposite fixing plates further improve the structural stability; by sequentially connecting the reinforcing plates to form several triangles, a stable supporting effect can be obtained; the connecting plate is arranged in an arc shape to match the shapes of the inner core and the protective layer of the wire, and the structure is more reasonably arranged and used to improve the overall strength of the structure;

[0021] On the one hand, the bend-resistant plate cooperates with the support plate to improve the anti-deformation and anti-bending capabilities. On the other hand, it increases the thickness of the support plate to enhance the structural strength and provides a better buffering effect when the wire is bent or impacted. The deformation groove provides a bending deformation space for the bend-resistant plate, thus preventing the bend-resistant plate from tearing. Description of the Drawings

Detailed Description of the Embodiment

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] An embodiment of the present application discloses a bend-resistant wire. Referring to Figure 1 , it includes a wire inner core 1 and a protective sheath 2. An anti-bending structure 3 is provided inside the protective sheath 2. The anti-bending structure 3 includes a deformable support plate 31. The support plate 31 is arc-shaped. One end of the support plate 31 forms a mounting plate 311, and the other end forms a mounting groove 312 into which the mounting plate 311 can be inserted. A plurality of arc-shaped support plates 31 are connected to each other and wrap around the wire inner core 1. The mounting plate 311 of one support plate 31 is inserted into the mounting groove 312 of the adjacent support plate 31.

[0027] Referring to Figure 1 , a bend-resistant plate 4 having a shape matching that of the support plate 31 is fixed to the outside of the support plate 31. On the one hand, the bend-resistant plate 4 cooperates with the support plate 31 to improve the anti-deformation and anti-bending capabilities. On the other hand, it increases the thickness of the support plate 31 to enhance the structural strength and provides a better buffering effect when the wire is bent or impacted.

[0028] Referring to Figure 1 , a plurality of deformation grooves 41 are formed at intervals on the side wall of the bend-resistant plate 4. The cross-section of the deformation groove 41 is an isosceles trapezoid that flares outward from the bend-resistant plate 4. The deformation groove 41 provides a bending deformation space for the bend-resistant plate 4, thus preventing the bend-resistant plate 4 from tearing. The cross-section of the deformation groove 41 is an isosceles trapezoid that flares outward from the bend-resistant plate 4, increasing the deformation space to improve the bend resistance.

[0029] Referring to Figure 1, the anti-bending structure 3 further includes a deformable fixing plate 32. The fixing plate 32 is fixed between the support plate 31 and the inner core 1 of the wire, and the fixing plates 32 are oppositely arranged on the same support plate 31 to support the support plate 31, so that there is a deformation space and a distance between the support plate 31 and the inner core 1 of the wire, thereby reducing the direct impact on the inner core 1 of the wire.

[0030] Refer to Figure 1 , the anti-bending structure 3 further includes a plurality of reinforcing plates 33 fixed between the opposite fixing plates 32. The plurality of reinforcing plates 33 are sequentially connected between the fixing plates 32 to form a plurality of triangles. By sequentially connecting the reinforcing plates 33 to form a plurality of triangles, a stable supporting effect can be obtained, and the structural stability can be further improved.

[0031] Refer to Figure 1 , an arc-shaped connecting plate 5 is fixed between the fixing plates 32 on the adjacent support plates 31. The connecting plate 5 is arranged in an arc shape to match the shape of the inner core 1 of the wire and the protective layer. The structure is more reasonable and is used to improve the overall strength of the structure.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
