Abstract

The utility model discloses a novel general rubber of waterproofing type cover removes flexible cable, it be by power core, sinle silk, the filling layer that blocks water, the area that blocks water form around covering and oversheath layer. Power core is provided with three groups, and the ground sinle silk is provided with a set ofly, and power core comprises conductor and power core insulating layer, the ground sinle silk comprises ground wire core conductor and ground sinle silk insulating layer, and three power core of group and a set of ground sinle silk be crowded the package inside the filling layer that blocks water jointly. The soft degree of this kind of cable is good, the difficult fracture of sinle silk, the moving cable who has characteristic such as counter -bending, corrosion -resistant, fire -retardant, waterproof again to the operational environment that the adaptation was removed.

Description

A kind of Novel waterproofing type general rubber set mobile flexible cable

Technical field

This utility model belongs to field of cables, particularly relates to a kind of Novel waterproofing type general rubber set mobile flexible cable.

Background technology

China is vast in territory, aboundresources, and along with the development of China's economic construction, the equipment that mobile place uses is more Coming the most, the especially place such as metallurgy, coal yard, chemical industry, building needs substantial amounts of mobile device.

In various Workplaces, the past we use manual operation efficiency the lowest, and we commonly use now Do mechanization operation.Owing to various mobile devices are to move back and forth rather than actionless in the course of the work, cable also will be with The equipment of wearing moves around.When equipment advances, cable can move forward together along with equipment, and when equipment retreats, cable can be along with setting For retreating together, operationally cable is often subject to " S " type or the bending of " 8 " font, forms cable again very when equipment is walked Big longitudinal pulling force, therefore cable core is easy to fracture, the most also can be frequently encountered by rainwater cable and be short-circuited.This will Ask on the one hand equipment should possess the defencive function to cable bend and will be away from rainwater, and under the working condition of mobile device, this Clearly it is difficult to accomplish, is therefore necessary for considering to make cable itself have certain bending resistance and waterproof ability, i.e. exists In certain bending radius, continuous bend thousand of times the most up to ten thousand times, cable is maintained to properly functioning, and conductor does not occurs Broken string, cable also will not be short-circuited when meeting water.The most also there is no a kind of removal cable with above performance.

Utility model content

This patent is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of softness is good, and core is not Easy fracture, has again the removal cable of the characteristic such as counter-bending, corrosion-resistant, fire-retardant, waterproof, to adapt to the new of the working environment of movement Type waterproofing type general rubber set mobile flexible cable.

This utility model takes techniques below scheme to realize: a kind of mobile soft electricity of Novel waterproofing type general rubber set Cable, it is made up of power wire core, wire core, the packed layer that blocks water, waterstop lapping layer and external sheath layer, described power wire core Being provided with three groups, wire core is provided with one group, and power wire core is made up of conductor and power wire core insulating barrier, described wire core Being made up of wire core conductor and wire core insulating barrier, three groups of power wire core and one group of wire core are jointly extruded in block water and fill out Fill inside layer, described in block water one layer of waterstop lapping layer of outer wrapping of packed layer, the outer wrapping of described waterstop lapping layer one layer External sheath layer.

Described power wire core insulating barrier and wire core insulating barrier use the rubber with ethylene-propylene diene copolymer as base material.

Cable jacket layer uses the fire-retardant rubber with neoprene as base material.

This utility model has the advantages that this kind of cable softness is good in sum, core not easy fracture, again There is the removal cable of the characteristic such as counter-bending, corrosion-resistant, fire-retardant, waterproof, to adapt to the working environment of movement.

Accompanying drawing explanation

Fig. 1 is this utility model cross-sectional structure schematic diagram.

Detailed description of the invention

As it is shown in figure 1, a kind of Novel waterproofing type general rubber set mobile flexible cable, it is by power wire core, wire core, blocks water Packed layer 5, waterstop lapping layer 6 and external sheath layer 7 form, and described power wire core is provided with three groups, and wire core is provided with one Group, power wire core is made up of conductor 1 and power wire core insulating barrier 2, and described wire core is by wire core conductor 3 and ground wire Core insulation layer 4 forms, and it is internal that three groups of power wire core and one group of wire core are extruded in the packed layer 5 that blocks water jointly, described in block water and fill out Fill one layer of waterstop lapping layer 6 of outer wrapping of layer 5, one layer of external sheath layer 7 of the outer wrapping of described waterstop lapping layer 6.

It is embodied as: described power wire core insulating barrier 2 and wire core insulating barrier 4 use with ethylene-propylene diene copolymer as base material Rubber.

Cable jacket layer 7 uses the fire-retardant rubber with neoprene as base material.

The conductor of this utility model cable is the 6th class soft copper conductor, uses multiply fine copper wire stock strand and multiple strand, and is The version that stock strand is identical with strand direction again, performance meets the soft copper conductor of GB/T3956-2008 the 6th class. improve cable Flexibility and ductility, so the flexibility of cable is good, the little cable that is of value to of bending radius uses in mobile occasion, conductor is not Can be pulled off disconnected with curved, extend the service life of cable.

Insulating barrier in this utility model be have high anti-tear and excellent electrical properties EPDM glue material extrude and Become, the most just increase the mechanical performance of power wire core, which improves the security performance of cable.

Have employed during this utility model stranding and block water packed layer 5 and waterstop lapping layer 6 improves blocking water and non-of cable Moisture absorption function.

This utility model external sheath layer 7 is to make with high anti-tear, corrosion-resistant, fire-retardant neoprene material, so machinery is strong Degree is brought up to present 15Mpa by original 11Mpa, and percentage elongation is brought up to present 450%, tear strength by original 150% Present 7N/ is brought up to by original 1～2N/ (pants type rectangularity)；There is excellent fire resistance and decay resistance.

This utility model has good bending resistance, electrical property, corrosion-resistant, fire-retardant and block-water performance etc., is particularly suitable for Equipment in mobile occasion uses.

The above is this utility model embodiment, thus all according to the structure described in this utility model application range, feature and The equivalence that principle is done changes or modifies, and is all included in this utility model patent claim.
