Description

technical field

The utility model relates to the technical field of cables and in particular to a kink-resistant parallel cable.

background technique

Larger diameter cables are often used in wind turbines for power transmission and typically parallel cables are fitted with multiple sets of cores such that the inside and outside of the cable will have different arc lengths when a shorter section of the parallel cable is bent over, resulting in this that some of the cores at the terminals of the cable inward, some out of the terminals, the cores appear relatively misaligned, resulting in uneven cable termination. This can affect the normal use of the cable.

Content of the utility model

The purpose of the utility model is to provide a kink-resistant parallel cable whose multiple sets of wire cores exposed at the connector remain flush and in place after bending to ensure normal usage.

The utility model is realized by the following technical solution: A kink-resistant parallel cable comprising a cable body, that the cable body is wrapped with a plurality of wire cores, the wire cores comprising two parts of core units and elastic telescopic elements connected to two adjacent core units by the elastic Telescopic elements are firmly connected and are arranged alternately.

Furthermore, the front end of the core unit is provided with a receiving slot, and that the two ends of the elastic telescopic element are firmly connected to the bottom of the receiving slot and to the rear end of the adjacent core unit, so that the elastic telescopic element is received in this receiving slot, if the cable body is not bent.

Furthermore, one end of the core unit is provided with auxiliary strips, the auxiliary strips being arranged evenly and spaced around the elastic telescopic element, and adjacent one end of the core unit there are sockets distributed around the receiving slot into which auxiliary strips fit and can slide.

Furthermore, the depth of the socket is greater than the depth of the receiving slot.

Furthermore, the auxiliary strip is made of brass.

Further, the elastic telescopic member is a spring made of conductive metal material.

The technical solution of the embodiment of the utility model has at least the following advantages and merits: Compared to the prior art, the parallel cable in the utility model may bend when laying around a corner during use. Thus, a wire core is divided into multiple core units and elastic telescopic elements are used for series connection, so that when the cable body is bent, the elastic telescopic elements can be compressed on the inside and compensated by stretching on the outside accordingly, thereby ensuring that the multiple cores connectors are not misaligned and the cable is properly connected after bending.

Specific Embodiments

In order to more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the utility model, the technical solutions in the embodiments of the utility model are described clearly and fully below in conjunction with the accompanying drawings in the embodiments of the utility model, it being understood that the described embodiments are part of the embodiments of the utility model and not all of them. The components of the embodiments of the utility model that are generally described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations.

Accordingly, the following detailed description of embodiments of the utility model illustrated in the accompanying drawings is not intended to limit the scope of protection of the utility model, but is merely to provide selected embodiments of the utility model. Based on the embodiments of the present utility model, all other embodiments achieved by a person skilled in the art without creative work fall within the scope of the present utility model.

Example 1

In the following, in connection with certain embodiments, reference is made to FIG 1 until 4 described that this embodiment 1 is a kink-resistant parallel cable, which comprises a cable body 1, that the cable body 1 is wrapped with a plurality of wire cores 11, the wire cores 11 comprising two parts of core units 111 and elastic telescopic elements 112, the are fixed to two adjacent core units 111 through the elastic telescopic members 112 and are arranged alternately. Specifically, each group of wire cores 11 of the parallel cable in the present utility model is formed by connecting two pieces of the core unit 111 and the telescopic elastic member 112 alternately. When the cable body 1 is bent during laying, the elastic telescopic member 112 can be compressed according to its inner bend or stretched according to its outer bend to make length compensation adjustment, thus ensuring that wire cores 11 are connected to the terminals of both ends of the cable body 1 will not slip and will be flush in normal use.

One end of the core unit 111 is provided with an auxiliary strip 3, which is evenly arranged around the elastic telescopic element 112, and one end of the adjacent core unit 111 is provided with a socket 4 around the receiving slot 2, in which the auxiliary strip 3 fits and can slide. In particular, the auxiliary strip 3 is added to enhance the torsional strength of the core wire 11 . The wire cores 111 are more strongly connected to each other so that they retain their conductivity and suppleness during stretching.

The depth of the bushing 4 is greater than the depth of the receiving slot 2. Since the elastic telescopic element 112 has an axial change in length, the depth of the bushing 4 ensures that it can always be extended and retracted synchronously with the elastic telescopic element 112.

The auxiliary strip 3 consists of brass, in particular brass with good toughness and electrical conductivity.

The elastic telescopic element 112 is a spring. The telescopic elastic member 112 is made of conductive metal material, in particular, the spring has good expansion and contraction recovery ability. The conductive metal material makes the entire wire core 11 more conductive and has better performance.

The above is only a preferred embodiment of the utility model and however the scope of protection of the utility model is not limited thereto; Should any person skilled in the art familiar with the prior art within the scope of the technology disclosed by the utility model make equivalent replacements or changes according to the technical solution of the utility model and its ideas for improvement, they will be included in the scope of protection of the utility model.
