Description

Technical Field

[0001] This utility model relates to the field of cross-linked cable technology, specifically to a cross-linked cable with a compressed conductor. Background Technology

[0002] Cross-linked cables with compressed conductors are made by drawing the round monofilaments of the cable core into shaped wires using a mold, and then twisting them into conductor cores using a unique process of pre-twisting and shaping molds, thereby increasing the compression coefficient of the conductor core.

[0003] Currently, the insulation and sheath layers of cross-linked cables with compressed conductors are generally made by mixing a single flame retardant with the cable material, resulting in poor flame retardant effect; the mechanical strength of cross-linked cables is generally low, which can easily affect the service life of cross-linked cables; cross-linked cables are susceptible to electromagnetic interference during use, which can easily affect the signal transmission effect of cross-linked cables. Utility Model Content

[0004] The purpose of this invention is to provide a cross-linked cable with a compressed conductor to solve the problems mentioned in the background art, such as poor flame retardant effect, which easily affects the service life of the cross-linked cable and poor signal transmission effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cross-linked cable with a compressed conductor, comprising a compressed conductor member, a cross-linked insulation layer wrapped around the outside of the compressed conductor member, a glass fiber wrapping tape disposed on the outside of the cross-linked insulation layer, a filler layer filling the space between the glass fiber wrapping tape and the cross-linked insulation layer, a sheath layer sleeved on the outside of the glass fiber wrapping tape, a reinforcing mechanism disposed on the outside of the compressed conductor member, the reinforcing mechanism comprising a steel strip layer and reinforcing components, a shielding mechanism disposed on the outside of the cross-linked insulation layer, the shielding mechanism comprising an anti-interference layer and shielding components, and a flame-retardant mechanism disposed between the glass fiber wrapping tape and the sheath layer, the flame-retardant mechanism comprising an oxygen barrier layer and flame-retardant components.

[0006] Preferably, the surface of the glass fiber tape is wrapped with a steel tape layer, and the outside of the cross-linked insulation layer is wrapped with a reinforcing component.

[0007] Preferably, the reinforcing component consists of an outer steel wire layer and an inner steel wire layer, the surface of the cross-linked insulation layer is stranded with the inner steel wire layer, and the surface of the inner steel wire layer is wound with the outer steel wire layer.

[0008] Preferably, an anti-interference layer is provided on the outside of the cross-linked insulating layer, the surface of the anti-interference layer is bonded and fixed to the surface of the outer steel wire layer, and a shielding component is provided on the outside of the glass fiber wrapping tape.

[0009] Preferably, the shielding component includes an inner shielding layer and an outer shielding layer. The outer side of the fiberglass wrapping tape is provided with an inner shielding layer. The surface of the inner shielding layer is bonded and fixed to the surface of the steel strip layer. The material of the inner shielding layer is high-toughness composite aluminum foil.

[0010] Preferably, an outer shielding layer is provided on the outside of the inner shielding layer, and the outer shielding layer is made of braided silver-plated copper wire.

[0011] Preferably, an oxygen barrier layer is provided on the outer side of the fiberglass wrapping tape, and the surface of the oxygen barrier layer is bonded and fixed to the surfaces of the inner shielding layer and the outer shielding layer, respectively. The oxygen barrier layer is a mica tape layer, and a flame-retardant component is provided on the outer side of the oxygen barrier layer.

[0012] Preferably, the flame-retardant component is composed of a low-melting-point glass powder layer and a heat-insulating and flame-retardant layer. The inner wall of the sheath layer is adhered with a low-melting-point glass powder layer, and the inner wall of the low-melting-point glass powder layer is adhered with a heat-insulating and flame-retardant layer. The heat-insulating and flame-retardant layer is composed of two materials: thermoplastic polyurethane elastomer and melamine cyanurate. The surface of the heat-insulating and flame-retardant layer is bonded and fixed to the surface of the outer shielding layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cross-linked cable with compressed conductor not only improves the flame retardant effect of the cross-linked cable during use, improves the mechanical strength of the cross-linked cable during use, and extends the service life of the cross-linked cable, but also improves the signal transmission effect of the cross-linked cable during use.

[0014] 1. By incorporating a flame-retardant mechanism, the low-melting-point glass powder layer acts as a flux when the cross-linked cable is burned, accelerating the flame-retardant effect of the flame-retardant material. Simultaneously, the heat-insulating flame-retardant layer, composed of thermoplastic polyurethane elastomer and melamine cyanurate, possesses flame-retardant properties, while the oxygen barrier layer, a mica tape layer, further enhances the flame-retardant function, thereby achieving highly efficient flame-retardant performance of the cross-linked cable and improving its flame-retardant effect during use.

[0015] 2. By setting up a reinforcing mechanism, the inner steel wire layer is twisted and wrapped around the outside of the cross-linked insulation layer, increasing the mechanical strength of each cable core. Under the action of the outer steel wire layer, the cable core is further strengthened. At the same time, under the action of the steel strip layer, the cross-linked cable is less likely to break or break, thus realizing the reinforcing function of the cross-linked cable, thereby improving the mechanical strength of the cross-linked cable during use and extending the service life of the cross-linked cable.

[0016] 3. With the shielding mechanism in place, the compressed conductor is less susceptible to external electromagnetic interference under the action of the anti-interference layer. At the same time, since the inner shielding layer is made of high-toughness composite aluminum foil and the outer shielding layer is made of braided silver-plated copper wire, the magnetic field outside the outer shielding layer can be isolated to realize the anti-electromagnetic interference function of the cross-linked cable, thereby improving the signal transmission effect when the cross-linked cable is used.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] The present invention provides a cross-linked cable with a compacted conductor, as shown in the following structure. Figure 1 and Figure 2 As shown, it includes a compressed conductor 1, the outside of which is wrapped with a cross-linked insulation layer 101, a glass fiber wrapping tape 103 is disposed on the outside of the cross-linked insulation layer 101, a filler layer 102 is filled between the glass fiber wrapping tape 103 and the cross-linked insulation layer 101, and a sheath layer 104 is sleeved on the outside of the glass fiber wrapping tape 103.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, a reinforcing mechanism 2 is provided on the outside of the compressed conductor 1. The interior of the reinforcing mechanism 2 includes a steel strip layer 201 and a reinforcing component 202. The surface of the glass fiber wrapping tape 103 is wrapped with the steel strip layer 201. The reinforcing component 202 is wrapped on the outside of the cross-linked insulation layer 101. The reinforcing component 202 is composed of an outer steel wire layer 2021 and an inner steel wire layer 2022. The surface of the cross-linked insulation layer 101 is twisted with the inner steel wire layer 2022, and the surface of the inner steel wire layer 2022 is wrapped with the outer steel wire layer 2021.

[0025] In use, the inner steel wire layer 2022 is twisted and wrapped around the outside of the cross-linked insulation layer 101 to increase the mechanical strength of each cable core. Under the action of the outer steel wire layer 2021, the cable core is further strengthened. At the same time, under the action of the steel strip layer 201, the cross-linked cable is less likely to break or break, thus realizing the strengthening function of the cross-linked cable.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, a shielding mechanism 3 is provided on the outside of the cross-linked insulation layer 101. The shielding mechanism 3 consists of an anti-interference layer 301 and a shielding component 302. The anti-interference layer 301 is sleeved on the outside of the cross-linked insulation layer 101. The surface of the anti-interference layer 301 is bonded and fixed to the surface of the outer steel wire layer 2021. A shielding component 302 is provided on the outside of the glass fiber wrapping tape 103. The shielding component 302 includes an inner shielding layer 3021 and an outer shielding layer 3022. The inner shielding layer 3021 is provided on the outside of the glass fiber wrapping tape 103. The surface of the inner shielding layer 3021 is bonded and fixed to the surface of the steel tape layer 201. The material of the inner shielding layer 3021 is high-toughness composite aluminum foil. The outer shielding layer 3022 is sleeved on the outside of the inner shielding layer 3021. The material of the outer shielding layer 3022 is braided silver-plated copper wire.

[0027] During use, the anti-interference layer 301 makes it less susceptible to external electromagnetic interference to the compressed conductor 1. Meanwhile, since the inner shielding layer 3021 is made of high-toughness composite aluminum foil and the outer shielding layer 3022 is made of braided silver-plated copper wire, the magnetic field outside the outer shielding layer 3022 can be isolated to achieve the anti-electromagnetic interference function of the cross-linked cable.

[0028] Furthermore, such as Figure 4As shown, a flame-retardant mechanism 4 is provided between the fiberglass wrapping tape 103 and the sheath layer 104. The flame-retardant mechanism 4 includes an oxygen barrier layer 401 and a flame-retardant component 402 inside. An oxygen barrier layer 401 is provided on the outside of the fiberglass wrapping tape 103. The surface of the oxygen barrier layer 401 is bonded and fixed to the surfaces of the inner shielding layer 3021 and the outer shielding layer 3022, respectively. The oxygen barrier layer 401 is a mica tape layer. The flame-retardant component 402 is provided on the outside of the oxygen barrier layer 401. The combustible component 402 is composed of a low-melting-point glass powder layer 4021 and a heat-insulating and flame-retardant layer 4022. The inner wall of the sheath layer 104 is adhered with the low-melting-point glass powder layer 4021, and the inner wall of the low-melting-point glass powder layer 4021 is adhered with the heat-insulating and flame-retardant layer 4022. The heat-insulating and flame-retardant layer 4022 is composed of two materials: thermoplastic polyurethane elastomer and melamine cyanurate. The surface of the heat-insulating and flame-retardant layer 4022 is bonded and fixed to the surface of the outer shielding layer 3022.

[0029] In use, the low-melting-point glass powder layer 4021 acts as a flux when the cross-linked cable is burned, accelerating the flame-retardant effect of the flame-retardant material. At the same time, the heat-insulating and flame-retardant layer 4022 is composed of thermoplastic polyurethane elastomer and melamine cyanurate, which has a flame-retardant effect. The oxygen barrier layer 401 is a mica tape layer, which further realizes the flame-retardant function, so as to achieve the high-efficiency flame-retardant function of the cross-linked cable.

[0030] Working principle: In use, the inner steel wire layer 2022 is first twisted and wrapped around the outside of the cross-linked insulation layer 101 to increase the mechanical strength of each cable core. Under the action of the outer steel wire layer 2021, the cable core is further strengthened. At the same time, under the action of the steel strip layer 201, the cross-linked cable is less likely to break or break, thus realizing the strengthening function of the cross-linked cable, thereby improving the mechanical strength of the cross-linked cable during use and extending the service life of the cross-linked cable.

[0031] At this time, under the action of the anti-interference layer 301, the compacted conductor 1 is not easily affected by external electromagnetic interference. Meanwhile, since the inner shielding layer 3021 is made of high-toughness composite aluminum foil and the outer shielding layer 3022 is made of braided silver-plated copper wire, the magnetic field outside the outer shielding layer 3022 can be isolated to realize the anti-electromagnetic interference function of the cross-linked cable, thereby improving the signal transmission effect when the cross-linked cable is used.

[0032] Meanwhile, the low-melting-point glass powder layer 4021 acts as a flux when the cross-linked cable is burned, accelerating the flame-retardant effect of the flame-retardant material. At the same time, since the heat-insulating and flame-retardant layer 4022 is composed of thermoplastic polyurethane elastomer and melamine cyanurate, it has a flame-retardant effect. The oxygen barrier layer 401 is a mica tape layer, which further realizes the flame-retardant function, so as to achieve the efficient flame-retardant function of the cross-linked cable, thereby improving the flame-retardant effect of the cross-linked cable during use, and finally completing the use of the cross-linked cable.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
