Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

The first embodiment of the present invention relates to a wire harness of an elevator cable, and as shown in fig. 1, fig. 2 and fig. 3, a wire harness 2 is detachably connected to an insulating sheath 1 of a cable, and the wire harness 2 is inserted into an arbitrary wire harness hole 11 of the insulating sheath 1 along a length direction of the cable.

In addition, as shown in fig. 3, the wire harness 2 includes: the wire core 21, the insulating layer 22 of cladding outside the sinle silk 21, and a plurality of recesses 221 are seted up around the axle center of sinle silk 21 to insulating layer 22, and arbitrary recess 221 all is used for when pencil 2 wears to locate the pencil hole 11 of insulating cover 1, is inserted by the arch 12 that sets up in pencil hole 11.

Through the above, it is easy to find that, in practical application, a worker can prepare the corresponding number of the wire harnesses 2 in advance according to practical requirements, and the corresponding number of the wire harnesses 2 are arranged in the corresponding wire harness holes 11 of the insulating sleeve 1 in a penetrating manner, so that the elevator cable of the embodiment can effectively reduce the production and use cost of the cable, and the worker can select the number of the wire harnesses 2 according to the requirements, so that the weight of the whole cable can be effectively controlled, and meanwhile, the power consumption of the elevator car during operation can be reduced, so that the use cost of the elevator can be further controlled. Moreover, because the insulating layer 22 of the wire harness 2 is provided with the plurality of grooves 221 around the axis of the wire harness, each groove 221 can be inserted by the protrusion 12 in the wire harness hole 11 when the wire harness is arranged in any wire harness hole 11 of the insulating sleeve 1, and the wire harness 2 can be limited by the matching of the groove 221 and the protrusion 12 in the wire harness hole 11, so that the rotation phenomenon of the wire harness 2 in the wire harness hole 11 is avoided.

In addition, it is obvious that since the wire harness 2 and the insulating sheath 1 of the present embodiment are detachably connected, both the wire harness 2 and the insulating sheath 1 can be manufactured as standard parts, so that the production and manufacturing costs of the cable can be further reduced.

Specifically, in the present embodiment, as shown in fig. 1, 2, and 3, the number of the protrusions 12 provided on the hole wall of the harness hole 11 is the same as and uniquely corresponds to the number of the slide grooves 221 on the insulating layer 22 of the harness 2. And any groove 221 is arranged along the axial direction of the wire harness 2 to form a through groove structure, and each groove 221 is annularly arranged around the axis of the wire harness 2 at equal intervals, so that after each groove 221 on the wire harness 2 is combined with each protrusion 12 in the wire harness hole 11, the acting force applied to the insulating layer 22 of the wire harness 2 by each protrusion 12 in the wire harness hole 11 can be uniformly distributed around the wire harness 2, and the phenomenon that the wire core 21 is broken due to overlarge local stress of the wire harness 2 is avoided.

The second embodiment of the present invention relates to an insulating sheath for elevator cables, which is further improved on the basis of the first embodiment, and the main improvement thereof lies in that, in this embodiment, as shown in fig. 4, each protrusion 12 provided in each wire harness hole 11 of the insulating sheath 1 is a rack. Accordingly, in order to better match the teeth 221 of the rack when the wire harness 2 is inserted into the harness hole 11, in the present embodiment, as shown in fig. 4, a protrusion 222 is further provided on the insulating layer 22 of the wire harness 2 at the groove bottom 2211 of any sliding groove 221, and the protrusion 222 can be used to be inserted into the tooth groove 122 formed between any two adjacent teeth 121 of the rack.

Specifically, when the wire harness 2 is inserted into any wire harness hole 11 of the insulating sleeve 1, each protrusion 222 arranged on the wire harness 2 can be directly embedded into the tooth groove 122 formed between any two adjacent teeth 121 of the rack, and through the cooperation of the protrusion 222 and any tooth groove 122, a certain locking force can be provided between the wire harness 2 and the protrusion 12 in the wire harness hole 11, so that the firmness of the wire harness 2 after penetrating into the wire harness hole 11 of the insulating sleeve 1 is improved, and the wire harness 2 is not easy to shake in the wire harness hole 11.

In the present embodiment, as shown in fig. 4, a plurality of the projections 222 may be provided in any of the slide grooves 221 of the wire harness 2, and the projections 222 may be arranged in the longitudinal direction of the slide groove 221. By providing the plurality of protrusions 222 in the sliding groove 221, the locking force between the wire harness 2 and the protrusion 12 can be further improved, so that the wire harness 2 is more stable after penetrating into any harness hole 11 of the insulating sheath 1. Further, in the present embodiment, preferably, the bump 222 is a flexible body and is integrally molded with the insulating layer 22, so that the strength of the wire harness 2 after being fitted to the insulating cover 1 can be further improved.

In addition, it is worth integrating that, in the present embodiment, the surface of the rack, i.e., each tooth 121 of the projection 12, is a cambered surface. The surface of the corresponding bump 222 is a spherical surface, and by the cooperation of the arc surface of each tooth 121 of the protrusion 12 and the spherical surface of the bump 22, a large locking force between the wire harness 2 and the protrusion 12 can be ensured, and by the cooperation of the arc surface of each tooth 121 of the protrusion 12 and the spherical surface of the bump 222, the resistance of the wire harness 2 in the process of being arranged in the wire harness hole 11 can be effectively reduced, so that the wire harness 2 can be more easily inserted into any wire harness hole 11 of the insulating sleeve 1.

Of course, it should be noted that, in practical applications, two sides of the protrusion 222 along the beam axis may also be inclined surfaces (not labeled in the drawings), and both inclined surfaces of the protrusion 222 extend from a side opposite to the groove bottom 2211 to a side far from the groove bottom 2211 and are inclined toward each other.

The third embodiment of the present invention relates to an insulation cover for an elevator cable, and the third embodiment is further improved on the basis of the second embodiment, and the main improvement thereof lies in that, in this embodiment, as shown in fig. 5, the aperture of one end of the wire harness hole 11 is larger than that of the other end, so that the whole wire harness hole 11 is tapered. The insulating layer 22 of the wire harness 2 is a cone completely matched with the hole wall of the wire harness hole 11, so that the wire harness 2 has directivity when penetrating into the wire harness hole 11 of the insulating sleeve 1, and the limiting effect when the wire harness 2 is penetrated can be achieved through the matching of the cone-shaped wire harness hole 11 and the cone-shaped wire harness 2.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
