The cross-section of the hybrid cable 10 comprises a central protective jacket portion 20 which houses within it at least one optical fiber 22, located in a central position of the central protective jacket portion 20 .
Pelo menos dois elementos de tração centrais 24 posicionados adjacentemente à pelo menos uma fibra ótica 22 ainda são providos na porção de capa protetora central 20 . Os elementos de tração centrais 24 que são preferencialmente cabos de aço são responsáveis por prover resistência à tração e/ou flexão do cabo híbrido 10 . At least two central pulling elements 24 positioned adjacent the at least one optical fiber 22 are further provided in the central protective cap portion 20 . The central traction elements 24, which are preferably steel cables, are responsible for providing tensile and/or bending resistance to the hybrid cable 10 .
[0017] O cabo híbrido 10 de acordo com a presente invenção compreende ainda pelo menos duas porções de capa protetora periférica 30, adjacentes à porção de capa protetora central[0017] The hybrid cable 10 according to the present invention further comprises at least two peripheral protective sheath portions 30 adjacent the central protective sheath portion
20 . Cada porção de capa protetora periférica 30 compreende pelo menos um condutor elétrico 32a, 32b responsável por transmitir corrente elétrica . Preferencialmente, o pelo menos um condutor elétrico 32a, 32b é composto por um feixe de fios metálicos, tal como cobre . Essa configuração garante maior flexibilidade do cabo frente ao que tem um único elemento . 20 . Each peripheral protective cap portion 30 comprises at least one electrical conductor 32a, 32b responsible for transmitting electrical current. Preferably, the at least one electrical conductor 32a, 32b comprises a bundle of metallic wires, such as copper. This configuration guarantees greater cable flexibility compared to a single element.
[0018] Na concretização preferencial ilustrada na figura[0018] In the preferred embodiment illustrated in the figure
1, duas porções de capa protetora periférica 30 são providas, sendo uma à esquerda e uma à direita da porção de capa protetora central 20 . Preferencialmente, cada um do pelo menos um condutor elétrico 32a, 32b é uma cordoalha que forma um feixe de fios metálicos condutores . Cada cordoalha de fios metálicos condutores é fabricada por meio do enrolamento dos fios metálicos em torno do eixo central da própria cordoalha . Preferencialmente, a primeira cordoalha de fios metálicos localizada na porção de capa protetora periférica 30 à esquerda da porção de capa protetora central 20 é fabricada pelo enrolamento dos fios metálicos no sentido horário, conforme indicado por uma seta na figura 1 . Ainda, preferencialmente, a segunda cordoalha de fios metálicos localizada na porção de capa protetora periférica 30 à direita da porção de capa protetora central 20 é fabricada pelo enrolamento dos fios metálicos no sentido anti-horário, conforme também indicado na figura 1 . 1, two peripheral protective cap portions 30 are provided, one being to the left and one to the right of the central protective capping portion 20 .

Still, preferably, the second strand of metallic wires located in the peripheral protective cover portion 30 to the right of the central protective cover portion 20 is manufactured by winding the metallic wires in a counterclockwise direction, as also indicated in Figure 1 .
[0019] O fato de o cabo híbrido da presente invenção ser simétrico e compreender duas cordoalhas de fios metálicos em lados opostos sendo fabricadas por enrolamento dos fios metálicos em sentidos também opostos faz com que a força elástica rotacional de cada uma das cordoalhas seja compensada pela outra, já que haverá forças rotacionais opostas e de igual intensidade . Esse cancelamento de forças evita o "efeito snake", bastante conhecido para um técnico no assunto e que consiste no enrolamento do cabo em torno de seu próprio eixo em um determinado sentido . [0019] The fact that the hybrid cable of the present invention is symmetrical and comprises two strands of metallic wires on opposite sides being manufactured by winding the metallic wires in opposite directions, makes the rotational elastic force of each of the strands to be compensated by the the other, since there will be opposite and equal rotational forces.

30 é conectada por uma porção de conexão 40 à porção de capa protetora central 20, a porção de conexão 40 sendo adaptada para rompimento facilitado para separação das porções de capa protetora periférica 30 da porção de capa protetora central30 is connected by a connecting portion 40 to the cap portion central protector 20, the connecting portion 40 being adapted for easy tearing for separating the peripheral protective cover portions 30 from the central protective cover portion 30
20. Dessa forma, a porção central do cabo híbrido 10, compreendendo a fibra ótica 22, pode ser facilmente separada das porções periféricas onde estão localizados os condutores elétricos 32a, 32b . Adicionalmente, na configuração onde as porções de capa protetora periféricas 30 compreendem elementos de tração periféricos 34 em seus interiores, mesmo separando-se as diferentes porções de capa do cabo híbrido20. In this way, the central portion of the hybrid cable 10, comprising the optical fiber 22, can be easily separated from the peripheral portions where the electrical conductors 32a, 32b are located. Additionally, in the configuration where the peripheral protective sheath portions 30 comprise peripheral pulling elements 34 in their interiors, even though the different cover portions of the hybrid cable are separated

[0022] Opcionalmente, a porção de capa protetora central[0022] Optionally, the central protective cover portion
20 compreende pelo menos um entalhe 26 na posição central onde está localizada a fibra ótica 22 . O entalhe, que preferencialmente possui um formato em "V", permite o rompimento facilitado e exposição da fibra ótica 22 quando de sua conexão a um dispositivo . Preferencialmente, dois entalhes 26 em "V" são providos em faces opostas da porção de capa protetora central 20 conforme ilustrado na figura 1 . 20 comprises at least one notch 26 in the central position where the optical fiber 22 is located. The notch, which preferably has a "V" shape, allows for easy breakage and exposure of the optical fiber 22 when connecting it to a device. Preferably, two "V" notches 26 are provided on opposite faces of the central protective cap portion 20 as illustrated in Figure 1 .
[0023] Preferencialmente, as capas protetoras central 20 e periféricas 30, bem como as porções de conexão 40 são fabricados a partir de um mesmo material . Mais preferencialmente, o material empregado é um material de baixo coeficiente de atrito que facilita o deslizamento do cabo híbrido 10 entre outros cabos e no interior de dutos .[0023] Preferably, the central 20 and peripheral 30 protective covers as well as the connecting portions 40 are manufactured from the same material. More preferably, the material employed is a material with a low coefficient of friction that facilitates the sliding of the hybrid cable 10 between other cables and within ducts.
Ainda preferencialmente, as capas protetoras central 20 e periféricas 30 e as porções de conexão 40 formam um elemento único . [0024] A configuração do cabo híbrido 10 exposta acima permite que o mesmo compreenda, ao mesmo tempo, uma dimensão consideravelmente menor do que os cabos híbridos conhecidos atualmente e uma alta resistência à tração e flexão . Even preferably, the central 20 and peripheral 30 protective caps and the connecting portions 40 form a single element. [0024] The configuration of the hybrid cable 10 exposed above allows it to comprise, at the same time, a considerably smaller dimension than the hybrid cables known today and a high tensile and flexural strength.
[0025] Portanto, conforme exposto acima, a presente invenção provê um cabo híbrido com dimensional bastante reduzido - quando comparado com os existentes no mercado - e ao mesmo tempo resistente a esforços de tração e flexão .[0025] Therefore, as explained above, the present invention provides a hybrid cable with a very reduced dimension - when compared to existing ones on the market - and at the same time resistant to traction and bending efforts.
Adicionalmente, o cabo híbrido aqui descrito é con s ide rave Iment e flexível quando comparado com os cabos híbridos do estado da técnica . Por fim, os diferentes elementos de transmissão (fibra e condutores elétricos) podem ser desvinculados entre si e ainda assim manter elementos de resistência a esforços (tração e flexão) independentes . Additionally, the hybrid cable described herein is considered flexible when compared to prior art hybrid cables. Finally, the different transmission elements (fiber and electrical conductors) can be disconnected from each other and still maintain independent stress resistance elements (traction and bending).
[0026] Inúmeras variações incidindo no escopo de proteção do presente pedido são permitidas . Dessa forma, reforça-se o fato de que a presente invenção não está limitado às configurações/concretizações particulares acima descritas . [0026] Numerous variations within the scope of protection of this application are permitted.
