Abstract
The utility model relates to an armored cable, in particular to an end fixing device when the load of the armored cable is extremely large, which comprises a joint body, an outer steel wire of the armored cable and an inner core wire of the armored cable. The middle of the joint body is provided with a round hole with a certain taper angle, the outer steel wire of the armored cable is dispersed and bended and then arranged in the taper hole of the joint body at the root of the armored cable. The utility mode is characterized in that a protecting sleeve for the inner core wire of armored cable is additionally arranged between the outer steel wire of the armored cable and the inner core wire of the armored cable. The utility model overcomes the defect of the prior art that the core wire is frequently damaged by the joint of the armored cable when the stress of the armored cable is extremely large.
Description
Technical field
The utility model relates to a kind of armoured cable, the end fixture when the load of armoured cable is very big especially, or be called the armour cable joint.
Background technology
The related armoured cable of the utility model is a kind of telecontrolled submergence rescue vehicle armoured cable of (also can be used for other similar devices) that is usually used in.It is the hanger rope that rises of telecontrolled submergence rescue vehicle, is bearing power and signal transmission mission between telecontrolled submergence rescue vehicle and the working mother boat again.Structurally, its skin is the very big steel wire of intensity, is responsible for bearing the suffered axial tension of armour cable; Internal layer is the power and the signal cable of multicore, is responsible for the transmission of power and signal.The effect of armour cable joint and function are under the prerequisite of reliably protecting cover wire to be fixed on winch or the equipment reliably in that the internal layer heart yearn is carried out.
Armour cable joint structure commonly used is at present seen Fig. 1, the centre of fittings body 1 is a circular hole with certain taper, armour cable cover wire 2 scatter and replication after pack in the taper hole of fittings body 1, when armour cable 4 is stressed, because the volume of the part of steel wire bending is greater than the volume of other parts, the diameter of dogleg section is greater than fittings body 1 taper hole end diameter, and armour cable 4 is drawing tighter and tighter in fittings body 1 under the effect of external force, thereby realizes the function of joint.The armour cable joint of this structure has good effect when little in that armour cable 4 is stressed.But,, make armour cable internal layer heart yearn 3 be subjected to corresponding extrusion stress because the exercising result of external force in fittings body 1 is that armour cable cover wire 2 is inwardly pushed; Stressed when big when armour cable 4, easily armour cable internal layer heart yearn 3 is damaged by pressure, make the signal transmission of armour cable 4 and the disabler of power transmission.
The utility model content
In order to overcome armour cable joint in the prior art in the stressed deficiency of fragile heart yearn when big of armour cable, the purpose of this utility model provides a kind of end fixture of armoured cable, even when armour cable stressed greatly (within the rupture strength of armour cable cover wire), this device can guarantee that also the armour core is not damaged.
The technical scheme in the invention for solving the technical problem is: comprise fittings body, armour cable cover wire, armour cable internal layer heart yearn, a circular hole that tapering arranged is established in the centre of fittings body, armour cable cover wire scatter and replication after pack in the taper hole of fittings body, in the root of armour cable, it is characterized in that between armour cable cover wire and armour cable internal layer heart yearn, adding armour cable internal layer heart yearn sheath;
Described armour core sheath is a steel design, and an end cross section is a wedge shape, closely cooperates in the root of armour cable and armour cable cover wire and armour cable internal layer heart yearn.
The utlity model has following advantage:
Adopt the utility model because of armour core shield clip between armour cable cover wire that bears external force and armour cable internal layer heart yearn, the extrusion stress that originally is applied on the armour cable internal layer heart yearn in the fittings body when armour cable is stressed is born by the very high steel armour cable internal layer heart yearn sheath of intensity, so effect that armour cable internal layer heart yearn does not stress, avoided armour cable internal layer heart yearn impaired possibility under the effect of extrusion stress, play the armour cable joint and both can bear big pulling force, guaranteed the purpose that heart yearn is not damaged again.
Description of drawings
Fig. 1 is an armour cable joint vertical section structure schematic diagram commonly used at present.
Fig. 2 is the end fixture structure schematic diagram of armoured cable of the present invention.
Embodiment
Below in conjunction with accompanying drawing the utility model mechanism and principle are described further.
As shown in Figure 2, the utility model comprises fittings body 1, armour cable cover wire 2, armour cable internal layer heart yearn 3, a circular hole (being taper hole) that tapering arranged is established in the centre of fittings body 1, armour cable cover wire 2 scatter and replication after pack in the taper hole of fittings body 1, in the root of armour cable 4, it is characterized in that: between armour cable cover wire 2 and armour cable internal layer heart yearn 3, add armour cable internal layer heart yearn sheath 5; Described armour core sheath 5 one end cross sections are wedge shape, closely cooperate in the root of armour cable 4 and armour cable cover wire 2 and armour cable internal layer heart yearn 3; Armour cable internal layer heart yearn sheath 5 is a steel design.
Technical solution adopted in the utility model is compared with the prior art scheme, has increased armour cable internal layer heart yearn sheath 5, and the structure of remainder is all identical with the mechanism of action and former technical scheme.But be clipped between the armour cable cover wire 2 and armour cable internal layer heart yearn 3 that bears external force because of armour core sheath 5, originally be applied in the fittings body 1 when armour cable 4 is stressed that extrusion stress on the armour cable internal layer heart yearn 3 is existing is born by the very high steel armour cable internal layer heart yearn sheath 5 of intensity, armour cable internal layer heart yearn 3 but is not subjected to the effect of any power, avoided armour cable internal layer heart yearn under the effect of extrusion stress, to be damaged, play the armour cable joint and both can bear big pulling force, guaranteed the purpose that heart yearn is not damaged again.
