摘要:
The invention relates to a method for optimizing the adjustment parameters of the braiding of armored sheathing by means of spindles, which are provided with coils of wire equipping a braiding machine, on a bundle of electric conductors, in addition to said bundle. According to the invention, the method consists in determining a single group (N) of spindles and a single group (M) of braiding wires for each diameter of a series (s1) of consecutive diameters of bundles of electric conductors in order to minimize the number of interventions required to adapt the braiding machine according to requirements.

Method for cleaning a braiding machine, particularly a machine for braiding electrical cables, said braiding machine comprising a plateau (12) for supporting an annular row of spindle drive members (14), characterized in that it comprises a step of equipping the machine with at least one cleaning tool (84), this cleaning tool comprising on the one hand means (90) configured to be driven by the members and, on the other hand, at least one guide element configured to be housed in slideways (32) for the movement of the tool, said guide element being configured to drive or to be equipped with a means (80) of cleaning said slideways, and a step of rotating said members so as to drive said cleaning means in said slideways.
摘要:
In a process of weaving metal conductor wires to form a metal woven shielding conductor layer over the outer surface of an insulated cable, the insulated cable is accompanied with one or more solder or tin wires. When the solder or tin wire is immersed in a molten metal plating solution, it melts down hence generating a spatial margin between the insulated cable and the metal woven shielding conductor layer. This prevents the insulated cable from biting with its outer surface into the metal woven shielding conductor layer when it is thermally expanded in the molten metal plating solution. As the metal woven shielding conductor layer is impregnated deeply with the molten metal, there are hardly generated gaps and undulations on the inner surface of the metal plating layer. Accordingly, the suppression of reflection and attenuation of a transmission signal will be improved.

The present disclosure relates to a composite cable, which comprises a first wire assembly and a second wire assembly, and each wire of the second wire assembly is surrounded by an insulating layer. The composite cable further comprises: a sheath made of insulating material and configured to enclose the first wire assembly and the second wire assembly; and a shield comprising different kinds of metal wires and configured to surround the first wire assembly, wherein the first wire assembly is capable of transmitting signals, and the second wire assembly is capable of transmitting power supply. The composite cable according to the present disclosure is excellent in shielding performance for different requirements.

It includes a lower tray (1) with rotatory coil holders (3) in "B" sense and a top tray (2) composed of: fixed crown (6), plate (5a) and ring (5b) and disk (4). Said plate and ring define a circumferential track (29) where coil holders (27) run, and there is a sinusoidal gap (26) where thread guides (24) of lower coil holders (3) run, crossing each other with the circumferential track (29). Coil holders (27) are driven in "A" sense by pullers (7, 8) fixed to the crown (6) and disk (4) and provided with alternative stems (33) guided by shoes or rollers (35) introduced in tracks (30, 31) of the plate (5a) and ring (5b); while a stem (33) pulls a coil holder (27) the others avoid the thread guides (24). When the coil holders (27, 3) of the top and lower trays run a circumferential path, a high number of revolutions is achieved.
摘要:
A method of producing a leakage graded coaxial cable having a braided shield (8), in which ends of the shield wire are dropped as braiding progresses. Gaps (11) in the shield having progressively increasing size are produced through which the radio frequency field leakage occurs, which facilitates providing a constant radio frequency field around the cable. The cable is coated with a jell flooding agent (20) prior to extrusion of its protection jacket, which fills the interstices and gaps of the shield, and solidifies to a waxy, semi-resilient consistency. The resulting cable can be coiled and flexed, maintaining its shield reliability, and rejects water and fluids in case pinholes in the jacket occur.
