Abstract

본 발명은 교환기등의 케이블에 관한 것으로서, 이는 특히 다량의 신호선이 연결되는 교환기 피시비와 외부의 전화선을 연결할 때 다량의 회선을 최소 직경의 직경의 케이블로 수용할 수 있으면서 신호잡음도 최소활 수 있도록 한 것이다. 본 발명은 상기와 같은 목적을 구현할수 있도록 비닐재 외피부재(14)내에 약 0.3mm 이하 직경의 심선(11)쌍을, 수 내지 수십쌍으로 접합시킨 심선(11)들과, 이들 심선(11)의 외부를 전체적으로 감싸는 비닐테이프 부재(12)와, 이 비닐 테이프 부재(12)의 외표면을 전체적으로 감싸고 있는 알루미늄 박막부재(13)와, 비닐 테이프 부재(12)와 알루미늄 박막부재(13)사이에 매입시킨 접지선(15)과, 이들을 전체적으로 외부에서 감싸는 외피부재(14)등으로 이뤄져 있는 교환기 등의 케이블을 제공 하는데 있다. 이러한 본 발명은 교환기 피시비와 외부 전화선이 연결되는 교환기 터미널 사이에 사용되는 케이블이 많은 회선을 수용하면서도 케이블에 포함하는 가닥수에 따른 직경이 작고 신호 잡음도 최소화 할 수 있는 효과가 있다.The present invention relates to a cable such as an exchanger, which is particularly capable of accommodating a large number of lines as a cable having a diameter of the smallest diameter when connecting an external telephone line with a switch PCB connected to a large number of signal lines so as to minimize signal noise. It is. According to the present invention, the core wires 11 in which a pair of core wires 11 having a diameter of about 0.3 mm or less in the vinyl sheath member 14 are bonded in several to several tens of pairs, and these core wires 11 are realized. Between the vinyl tape member 12, the aluminum tape member 12, and the vinyl tape member 12 and the aluminum thin film member 13, which entirely surround the outer surface of the vinyl tape member 12. It is to provide a cable such as an exchanger, which is composed of a ground wire 15 embedded therein and a sheath member 14 or the like that surrounds the outside as a whole. The present invention has the effect that the cable used between the switch PCB and the exchange terminal to which the external telephone line is connected has a small diameter according to the number of strands included in the cable while minimizing signal noise.

Claims

The core wires 11 in which several to several tens of pairs of the core wires 11 having a diameter of about 0.3 mm or less are bonded to the vinyl material member 14, and the vinyl tape member 12 which surrounds the outside of the core wires 11 as a whole. And a ground wire 15 which covers the entire outer surface of the vinyl tape member 12 and is embedded between the aluminum thin film main body 13 and the vinyl tape member 12 and the aluminum thin film member 13, and these are entirely external. Cables such as exchangers, characterized in that made of a shell member (14) and the like wrapped around.

The core wires 11 of the cable 1 are twisted in pairs for each line, and the pitch pitch a of these pairs of core wires 11a and 11b is about 15 to 29 mm. Cable as exchanger.

2. The cable of an exchanger according to claim 1, wherein the twist pitch b when dividing the set of pairs of core wires into two strands and twisting them in the range of about 110 to 130 mm is finally twisted.

※ Note: It is to be disclosed according to the original application.
