Description
Technical Field
The utility model relates to the field of aircraft electrical circuit interconnection systems, in particular to a motion cable assembly.
Background
In some moving mechanisms in an aircraft, more electric equipment such as aircraft hydraulic actuators, deicing and heating equipment, various doors and the like are installed, and therefore, the equipment needs a larger number of electric wires and cables. Typically, a large number of wires and cables need to be arranged to facilitate installation and maintenance. The conventional wiring method is arranged as follows according to the equipment: one is to arrange the devices collectively, where all the electric wires and cables are designed integrally as a single wire harness, and preferably to screw the wire harness, such a screw harness saves space while allowing flexible length change within a certain range. Another is to distribute the devices in a decentralized manner, in which case the corresponding line paths are likewise distributed.
However, these wiring methods all have their own limitations. In the case of centralized arrangement of the devices, too many electric wires and cables may cause an excessively large diameter of the wire harness, difficulty in manufacturing (difficulty in spiraling), and an excessively large occupied space, which may cause an excessive winding of the wire harness, with a safety risk. In the case of the distributed arrangement of the devices, although there is no problem in manufacturing, the overall arrangement difficulty is increased, and the installation space of the devices and the wiring is increased as a whole.
Therefore, a wiring method capable of overcoming the above-described wiring problems is desired at present.

Further, the spiral wire harness further comprises a third sub-spiral wire harness, wherein the second sub-spiral wire harness is nested in the third sub-spiral wire harness.
Preferably, the strand cross-sectional diameter of the first sub-spiral strand is smaller than the strand cross-sectional diameter of the second sub-spiral strand, so that the first sub-spiral strand is entirely located within the inner space of the second sub-spiral strand.
Further preferably, the strand cross-sectional diameter of the second sub-spiral strand is smaller than the strand cross-sectional diameter of the third sub-spiral strand, so that the second sub-spiral strand is entirely located within the inner space of the third sub-spiral strand.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings in order to more clearly understand the objects, features and advantages of the present invention.
The various features and configurations of the motion cable assembly presented herein are discussed without additional external forces.
The term "strand cross-sectional diameter" as used herein refers to the diameter of the cross-section of the overwrap (shown in phantom lines in the figures) that encloses all of the integrated wires.
The term "strand outer diameter" as used herein refers to the diameter of the cross-section of a spiral strand or sub-spiral strand.
The term "physical phase staggering" as used herein means: if in any section of the spiral bundle of the moving cable assembly the two sub-spiral bundles in the spiral bundle are of different shapes or of the same shape but rotated at an angle with respect to each other, the physical phase of the two sub-spiral bundles is said to be staggered.
The term "pitch" as used herein refers to the spacing between every two turns of the helix in the helix bundle. Note that in the embodiments described herein, the pitch in the spiral bundle is uniform for ease of manufacturing.
Fig. 1 shows a schematic view of a related art single-screw type moving cable assembly, and fig. 2 shows a schematic view of a wire harness section of the single-screw type assembly of fig. 1. The single-screw type moving cable assembly includes a single-screw harness 1 and a connector, the single-screw harness 1 being connected to the connector at both ends via accessories. As can be seen from FIGS. 1-2, the single-helix wire harness 1 has a harness outer diameter L of
L＝k×l
Where k is a coefficient and l is a cross-sectional diameter of the wire harness of the single spiral wire harness 1, in the present invention, in order to ensure that the spiral wire harness receives the most appropriate tension during the movement of the cable, the spiraling of the spiral wire harness is optimal, and therefore, the proportional relationship between the outer diameter of the wire harness of the spiral wire harness and the cross-sectional diameter of the wire harness is constant regardless of the material, that is, k is constant. In other words, as long as the wire harness cross-sectional diameter is determined, the wire harness outer diameter can be determined.
It is known that the single-screw type moving cable assembly of fig. 1 is not easy to manufacture the harness section of the single-screw wire harness 1 due to the excessive number of integrated electric wires and cables. To overcome this problem, the kinematic cable assembly shown in fig. 3-5 was designed.
Fig. 3 shows a schematic view of a moving cable assembly according to an embodiment of the present invention, which includes a spiral harness 10 and a connector, the spiral harness 10 being connected to the connector at both ends via accessories.
The spiral wire harness 10 is split into a first sub-spiral wire harness 11, a second sub-spiral wire harness 12 and a third sub-spiral wire harness 13, wherein the first sub-spiral wire harness 11 is nested in the second sub-spiral wire harness 12, and the second sub-spiral wire harness 12 is nested in the third sub-spiral wire harness 13.
Preferably, the strand cross-sectional diameter l of the first sub-spiral strand 111Is smaller than the wire harness cross-sectional diameter l of the second sub-spiral wire harness 122So that the first sub-spiral wire harness 11 is completely located within the inner space of the second sub-spiral wire harness 12, and the wire harness cross-sectional diameter l of the second sub-spiral wire harness 122Is smaller than the cross-sectional diameter l of the third sub-spiral line bundle 133So that the second sub-spiral strand 12 is entirely located within the inner space of the third sub-spiral strand 13 (as can be seen from the above, as long as the strand cross-sectional diameter is determined, the strand outer diameter can be determined). This structure allows the sub-spiral wire harness having a small wire harness cross-sectional diameter to smoothly pass through the sub-spiral wire harness having a large wire harness cross-sectional diameterThe spiral strands such that the first sub-spiral strand 11, the second sub-spiral strand 12, and the third sub-spiral strand 13 can be more conveniently arranged together. In this case, the harness outer diameter L' of the spiral harness 10 is the harness outer diameter of the third sub-spiral harness 13:
L′＝k×l3
where k is a coefficient.
Obviously, in the case where the number of wires inside is small (because the wires are split into different sub-spiral bundles), the bundle cross-sectional diameter l of the third sub-spiral bundle 133The diameter of the wire harness section is smaller than that L of the single spiral wire harness 1, so that L' is less than L, and the purposes of saving wiring space and reducing manufacturing difficulty are achieved.
In additional embodiments, two sub-spiral strands, e.g., a first sub-spiral strand and a second sub-spiral strand, may have the same strand cross-sectional diameter, in which case the first sub-spiral strand and the second sub-spiral strand may be nested within each other in an alternating manner.
Preferably, the wires in the first sub-spiral bundle 11, the second sub-spiral bundle 12 and the third sub-spiral bundle 13 are split according to signal categories, and such classification has a function of enhancing signal isolation.
The physical phases of the first sub-spiral wire harness 11, the second sub-spiral wire harness 12 and the third sub-spiral wire harness 13 are staggered, so that the overall stress is balanced in the movement process of the cable, and the overall shape is not deformed. Further, referring to fig. 3 and 4, pitches of the first sub-spiral strand 11, the second sub-spiral strand 12, and the third sub-spiral strand 13 are different from each other.
Although the motion cable assembly including three sub-helix strands is described in detail in the embodiments herein, it should be understood that the helix strands of the motion cable assembly may include two or at least four sub-helix strands. For example, in additional embodiments, the helical strands of the sports cable assembly of the present invention may include a first sub-helical strand and a second sub-helical strand, with the first sub-helical strand nested within the second sub-helical strand. In yet further embodiments, the helical strands of the sports cable assembly of the present invention may include a first sub-helical strand, a second sub-helical strand, a third sub-helical strand, and a fourth sub-helical strand, configured such that the first sub-helical strand is nested in the second sub-helical strand, the second sub-helical strand is nested in the third sub-helical strand, and the third sub-helical strand is nested in the fourth sub-helical strand.
The utility model designs an integrated motion cable assembly aiming at the motion mechanism with more leads, and solves the problems of difficult manufacture and large installation space of the traditional scheme.
While the structure and method of installation of the present invention has been described in connection with the preferred embodiments, it is to be understood by those skilled in the art that the above examples are intended in an illustrative rather than in a limiting sense. Thus, modifications and variations may be made to the present invention which fall within the scope of the claims appended hereto.
