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 utility model discloses a first embodiment relates to a can dismantle elevator cable, as shown in fig. 1, include: insulating cover 1 and at least one pencil 2, this insulating cover 1 sets up a plurality of pencil hole 11 along the length direction of cable, and each pencil hole 11 all is used for the wearing and tearing of pencil 2 to establish.
As shown in fig. 3, in the present embodiment, the wire harness 2 includes: the cable comprises a cable core 21 and an insulating layer 22 coated outside the cable core 21, wherein the insulating layer 22 is detachably connected with the insulating sleeve 1.
In practical application, a worker can prepare corresponding number of wire harnesses 2 in advance according to actual requirements, and the corresponding number of wire harnesses 2 are arranged in each corresponding wire harness hole 11 of the insulating sleeve 1 in a penetrating mode, so that the elevator cable can be easily seen.
In addition, it is easy to see 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.
It should be noted that, as shown in fig. 2, in the present embodiment, in the insulating sheath 1, a plurality of protrusions 12 are annularly provided on the hole wall of each harness hole 11, and in the corresponding harness 2, as shown in fig. 3, a plurality of sliding grooves 221 into which any protrusion 12 can be inserted are provided in the insulating layer 22 along the longitudinal direction of the harness 2. Also, the number of the protrusions 12 in any of the harness holes 11 is the same as, and uniquely corresponds to, the number of the slide grooves 221 on the insulating layer 22 of any of the harnesses 2. And each protrusion 12 and the insulating sleeve 1 can be made of the same material and are integrally formed with the insulating sleeve 1. For example, rubber, silicone, or plastic may be used.
Specifically, in the present embodiment, as shown in fig. 1 and fig. 2, any protrusion 12 is disposed along the length direction of the wire harness hole 11, in the assembling process, as shown in fig. 1, each sliding groove 221 of the wire harness 2 can be aligned with each protrusion 12 on any wire harness hole 11, then the wire harness 2 is inserted into the corresponding wire harness hole 11 of the insulating sleeve 1, and by the cooperation of each protrusion 12 in the wire harness hole 11 of the insulating sleeve 1 and each sliding groove 221 of the wire harness 2, the wire harness 2 can be inserted into the wire harness hole 11 for guiding, and the wire harness 2 can be effectively prevented from rotating in the wire harness hole 11, so that when the terminal connector is electrically connected to the wire core 21 of each wire harness 2, the wire core torsion caused by the rotation of the wire harness 2 can be avoided, and the wire core fracture phenomenon can be avoided, thereby improving the service life of the cable.
Of course, as a preferable scheme, in any harness hole 11, each protrusion 12 is annularly arranged around the axis direction of the harness hole 11 at an equal distance, and each sliding groove 221 provided on the insulating layer 22 of the harness 2 is also annularly arranged around the axis direction of the harness 2 at an equal distance, so that the acting force applied to the insulating layer 22 of the harness 2 by each protrusion 12 in the harness hole 11 can be uniformly distributed around the harness 2, and the phenomenon that the wire core 21 is broken due to overlarge local stress of the harness 2 is avoided.
The second embodiment of the present invention relates to a detachable elevator cable, and the second embodiment is further improved on the basis of the first embodiment, and the main improvement lies in that, as shown in fig. 4, in this embodiment, each protrusion 12 disposed in each wire harness hole 11 of the insulating sheath 1 is a rack.
As can be seen from the above, since each protrusion 12 provided in the wire harness hole 11 of the insulating cover 1 in the present embodiment has a rack structure, the friction coefficient between the protrusion 12 and the groove bottom of the sliding groove 221 can be reduced by each tooth on the rack structure, so that the wire harness 2 can be more easily inserted into any wire harness hole 11 of the insulating cover 1.
In addition, in the present embodiment, as shown in fig. 4, a projection 222 is further provided on the insulating layer 22 of any wire harness 2 at the groove bottom 2211 of the chute 221, and the projection 222 can be used to be fitted into the tooth groove 122 formed between any two adjacent teeth 121 of the rack bar.
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 can be 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 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.
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 222, the large locking force between the wire harness 2 and the protrusion 12 can be ensured, and simultaneously, 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.
The third embodiment of the present invention relates to a detachable 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.
