Abstract
The utility model provides a kind of hollow flexible cable, belongs to field of cable technology.It solve the problem that existing cable is difficult to stretch.This cable comprises the housing in strip and is positioned at the wire of housing, housing is made up of elastomeric material, have multiple along the equally distributed cavity in shell length direction in housing, a part of helical buckling of wire is in cavity, and a part for wire is fixed in housing.This cable arranges equally distributed cavity in housing, and makes wire spiral be positioned at cavity, makes cable have good tensile property.
Description
Technical field
The utility model belongs to field of cable technology, relates to a kind of hollow flexible cable.
Background technology
General cable is all made up of shell body and the wire being positioned at housing.In use, cable is generally non-stretchable.This situation finds that after completing when cable arrangements cable length is more inconvenient slightly in short-term.If connect a shorter cable on original cable again, also seem and bother very much.If firmly pull original cable, the length of cable may stretch a little, but careless slightly, and cable is just likely pulled off.
Summary of the invention
In order to solve the problem, the utility model provides the stretchable hollow flexible cable of a kind of length.
The purpose of this utility model realizes by following technical proposal:
A kind of hollow flexible cable, comprise the housing in strip and the wire being positioned at housing, described housing is made up of elastomeric material, it is characterized in that, have multiple along the equally distributed cavity in shell length direction in described housing, a part of helical buckling of described wire is in cavity, and a part for described wire is fixed in housing.
Because housing is made up of elastomeric material, add and arrange equally distributed cavity in housing, when housing is by force-extension, housing is elongated.In addition, because wire helically bends in housing, when cable is elongated, wire has the larger surplus be elongated in housing.
In above-mentioned hollow flexible cable, described cavity is 1-8cm along the length in shell length direction.Arrange above-mentioned suitable cavity length, while cable can be effectively elongated, housing is also not easily pulled off.
In above-mentioned hollow flexible cable, described wire be positioned at cavity stretching after length be the 1.1-1.5 of cavity unstretched length doubly.The length arranging wire is 1.1-1.5 times of cavity length, and make when cable is elongated, wire has enough stretching surpluses, the waste simultaneously also avoiding wire unnecessary.
In above-mentioned hollow flexible cable, described cavity is cylindric, and the diameter of cavity is 5-8 times of diameter of wire.Above-mentioned suitable cavity size is set, ensures that the effective helical buckling of wire is in housing.
In above-mentioned hollow flexible cable, described wire forms by many copper cash are stranded.Stranded wire has good bending property, makes wire effectively can be positioned at cavity.
Compared with common cable, this cable arranges equally distributed cavity in housing, and makes wire spiral be positioned at cavity, makes cable have good tensile property.
Accompanying drawing explanation
Fig. 1 is the structural representation of this hollow flexible cable;
Fig. 2 is the structural representation after this hollow elasticity cable tensile strain.
In figure, 1, housing; 2, wire; 3, cavity.
Embodiment
As shown in Figure 1, this hollow flexible cable, comprise the housing 1 in strip and the wire 2 being positioned at housing 1, housing 1 is made up of elastomeric material, have multiple along the equally distributed cavity 3 of housing 1 length direction in housing 1, a part of helical buckling of wire 2 is in cavity 3.
In order to allow wire 2 have good bending property, wire 2 forms by many copper cash are stranded, like this, makes wire 2 can effectively be positioned at cavity 3.
Concrete, cavity 3 is cylindric, and cavity 3 is 1cm along the length of housing 1 length direction.As other belt body scheme, cavity 3 is 3cm or 8cm along the length of housing 1 length direction.Arrange above-mentioned suitable cavity 3 length, while cable can be effectively elongated, housing 1 is also not easily pulled off.
Wire 2 be positioned at cavity 3 stretching after length be 1.1 times of cavity 3 unstretched length, like this, when cable is elongated, wire 2 has enough stretching surpluses, the waste simultaneously also avoiding wire 2 unnecessary.Alternatively, wire 2 be positioned at cavity 3 stretching after length be 1.5 times of cavity 3 unstretched length
A part for wire 2 is fixed in housing 1.And the diameter of cavity 3 is 5 times of wire 2 diameter.Above-mentioned suitable cavity 3 size is set, ensures that the effective helical buckling of wire 2 is in housing 1.Alternatively, the diameter of cavity 3 is 8 times of wire 2 diameter.
Because housing 1 is made up of elastomeric material, add and arrange equally distributed cavity 3 in housing 1, when housing 1 is by force-extension, housing 1 is elongated.In addition, because wire 2 helically bends in housing 1, when cable is elongated, wire 2 has the larger surplus be elongated in housing 1.
As shown in Figure 2, when after this cable tensile strain, while housing 1 is elongated, the wire 2 being positioned at cavity 3 part is stretched, and makes this cable have good tensile property.
