Abstract
The invention discloses an electric cable with strong waterproof capability, comprising an outer sheath (1), a shielding layer (2), an inner sheath (4), and cable cores (6). Each cable core (6) is coated with an insulating layer (5). A lubricating layer (3) is arranged between the shielding layer (2) and the inner sheath (4). The cross section of the outer sheath (1) is a curved triangle. The outer side of the outer sheath (1) is coated with a cooling material. A waterproof layer (7) is arranged between the outer sheath (1) and the shielding layer (2). The insulating layers (5) are bonded by epoxy resin adhesive. The beneficial effects are as follows: the shielding layer effectively shields the interference of the external electromagnetic field to the electric cable; through the lubricating layer (3), the shielding layer and the inner sheath can rotate relative to each other, the inner sheath is not twisted when the outer sheath is twisted under the action of external force, and abrasion between the inner sheath and the shielding layer is avoided; and the waterproof layer effectively prevents water from permeating into the electric cable.
Description
Technical field
The present invention relates to field of cables, specifically, be the cable that a kind of waterproof ability is strong.
Background technology
Along with the high speed development of electronic communication technology, the spring telephone cable that various electronic communication systems are supporting is required more and more higher by it, and high resiliency to be possessed, high abrasion and softness etc. the most also should have miniaturization, lightweight, jamproof characteristic.After currently used telephone cable has four core insulations, squeeze elastic body jacket；Also have multiple twin after two pairs of conductor insulations, then squeeze elastic body jacket.Above two structure, in the case of compatible materials, can meet the requirement of high resiliency, high abrasion, but cannot resist the interference of external electromagnetic ripple, and two between there is also and interfere.In order to anti-tampering, some cables structurally adjust, and woven shielding, finally squeeze elastic body jacket after insulating core stranding, this structure not only overall dimensions is big, core between the cable that still there are of interference to every pair of braiding split screen, woven again total screen after split screen, although this structure can resist the Electromagnetic Interference in the external world also eliminate every pair simultaneously between interfere, physical dimension is huge, weight penalty, elastic poor with bendability, it is impossible to meet laying of small space.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, lay conveniently, cable that anti-twisting property is strong.
The present invention is achieved through the following technical solutions: the cable that a kind of waterproof ability is strong, the screen layer including oversheath, being arranged in oversheath, the inner sheath being arranged in screen layer and the cable core being arranged in inner sheath, cable core is coated with insulating barrier, lubricating layer it is provided with between screen layer and inner sheath, the cross section of oversheath is curved line trangle, scribble High tailored coating outside oversheath, between oversheath and screen layer, be provided with waterproof layer, by the bonding setting of epoxy resin adhesive between insulating barrier.
Described oversheath is the oversheath being made up of PVC.
Described screen layer is the screen layer being made up of copper mesh.
It is filled with lubricant in described lubricating layer.
Described lubricant uses graphite powder or lubricating oil.
Described insulating barrier is the insulating barrier being made up of ceramic silicon rubber.
Described waterproof layer is the waterproof layer being made up of waterproof yarn.
The present invention compared with prior art, has the following advantages and beneficial effect:
null(1) present invention can effectively shield the external electromagnetic field interference to cable by arranging screen layer，By arranging lubricating layer，Can make to relatively rotate between screen layer and inner sheath，Avoiding oversheath to be affected by external force when twisting makes inner sheath also twist，Avoid wearing and tearing between inner sheath and screen layer，Extend the service life of cable and improve the anti-twisting property of cable，By oversheath is designed as curved line trangle，The effect of guiding can be played when laying，Be conducive to avoiding cable to twist，Cable inside is avoided to produce stress because of twisting，Curved line trangle also has good flow conductivity，It is prevented from rainwater to remain on cable，By brushing High tailored coating，Effectively the heat within cable can be radiated the external world，And play the effect of anti-ultraviolet，High tailored coating also has good self-cleaning property，Be conducive to avoiding dust to pile up on cable，Can be prevented effectively from inside moisture immersion cable by arranging waterproof layer，Cable internal part is avoided to be corroded or damage because of making moist，Extend the service life of cable，And it is prevented from electric leakage，The bonding strength that can improve between insulating barrier by making insulating barrier bond together，And avoid wearing and tearing mutually between insulating barrier and causing the situation of short circuit，Improve the security performance of cable and extend the service life of cable，Epoxy resin；
(2) present invention can also improve the tension compressive property of cable by arranging copper mesh screen layer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cable that a kind of waterproof ability is strong；
Wherein 1 oversheath, 2 screen layers, 3 lubricating layers, 4 inner sheaths, 5 insulating barriers, 6 cable cores, 7 waterproof layers.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
nullAs shown in Figure 1，In the present embodiment，The cable that a kind of waterproof ability is strong，Including the oversheath 1 being made up of PVC、Be arranged in oversheath 1 by copper mesh make screen layer 2、The inner sheath 4 being arranged in screen layer 2 and the cable core 6 being arranged in inner sheath 4，The external electromagnetic field interference to cable can be effectively shielded by arranging screen layer，Cable core 6 is coated with the insulating barrier 5 being made up of ceramic silicon rubber，Lubricating layer 3 it is provided with between screen layer 2 and inner sheath 4，It is filled with graphite powder or lubricating oil in described lubricating layer 3，By arranging lubricating layer，Can make to relatively rotate between screen layer and inner sheath，Avoiding oversheath to be affected by external force when twisting makes inner sheath also twist，Avoid wearing and tearing between inner sheath and screen layer，Extend the service life of cable and improve the anti-twisting property of cable，The cross section of oversheath 1 is curved line trangle，High tailored coating is scribbled outside oversheath 1，The waterproof layer 7 being made up of waterproof yarn it is provided with between oversheath 1 and screen layer 2，Waterproof yarn has good water absorbing properties，Can be prevented effectively from inside moisture immersion cable by arranging waterproof layer，Cable internal part is avoided to be corroded or damage because of making moist，Extend the service life of cable，And it is prevented from electric leakage，By the bonding setting of epoxy resin adhesive between insulating barrier 5，The bonding strength between insulating barrier can be improved with this，And avoid wearing and tearing mutually between insulating barrier and causing the situation of short circuit，Improve the security performance of cable and extend the service life of cable，Epoxy resin adhesive has good adhesive property and heat resistance，Can avoid under the high temperature conditions losing efficacy by Canis familiaris L..
