摘要:
A shielded electric cable (10) having a core including an insulated conductor (11). A first shielding member (13) formed of an elongated ribbon of insulating material (13a) a pair of elongated metal foil strips (13b) and (13c) arranged in a parallel relationship with the ribbon (13a) and bonded to the opposite side of the ribbon is applied longitudinally to the core and wrapped circumferentially there around forming two concentric substantially closed shielded layers. A layer of plastic material (14), preferably foamed, surrounds the first shielding member and a second shielding member (15) surrounds the plastic layer, the second shielding member being formed of non-braided metallic material. The layer of plastic material is bonded to the shielding members. The shielded electric cable is provided with an outer jacket (16) of non-conducting material and having an appropriate O.D. for receiving a standard connector.

The optical connection system comprises at least one optical connection element consisting of three distinct parts A,B,C. Part A comprises a pumping-type optical contact (A0), the calibrated end part (41) of which is for an optical fibre cable; part B comprises, at one extremity, a calibrated end part (44) identical to that of part A and, at the other extremity, a lens-type optical contact (45) for optically connecting a corresponding optical connection element; part C comprises a calibrated guide system (47) for receiving the calibrated end parts of parts A and B, contacting their corresponding ends and coaxially aligning, with a high degree of precision, the two end parts. Application: in the transmission of video signals.

摘要:
A cable includes an inner conductor, an inner dielectric, and a guard conductor, where the inner dielectric is between the inner conductor and the guard conductor. The cable also includes an outer dielectric, and a shield conductor, where the outer dielectric is between the guard conductor and the shield conductor. The cable further includes an additional layer of material between the outer dielectric and the shield conductor of suitable composition for reducing triboelectric current generation between the outer dielectric and the shield conductor to less than that which would occur were the outer dielectric and the shield conductor to directly adjoin each other.
摘要:
[Problem] To provide a coaxial cable which is able to shut off external noises and transmit clear images having no picture disturbance by noises without employing cable compensators over a long distance. [Means for Solution] A first conductor is provided on the outer circumference of a central conductor with an insulator therebetween, a second conductor is provided on the concentric circle having central conductor as its center and outside the first conductor with an insulator therebetween, a coaxial cable formed by coating the outside of the second conductor which is on the concentric circle having the central conductor as its center by insulating external coating is provided, a DC voltage source which is able to apply DC voltage having a predetermined voltage value between the first conductor and the second conductor such that the direct current flowing in the first conductor and the second conductor takes a desired value is provided, and a noise barrier zone formed by the electro-magnetic action of the desired current is formed in the part surrounded by the first conductor and the second conductor on the outer circumference of the central conductor.
