The insulative housing features a tail side, a header aspect, a longitudinal slot disposed on the tail side, a plurality of slits disposed on the tail side and arranged perpendicularly across the longitudinal slot and a plurality of apertures extending from the header side that are in **unication with respective slits. At lower frequencies or for shielding from electromag**ic interference copper is less efficient, and nickel, iron and chromium are preferred. Electroless plating is used to deposit a really thin **ductive layer on the cable in order that a present ** be applied to the surface within the electrolytic plating step, the majority of the shielding layer being deposited by electrolytic plating. Only a very skinny shielding layer is required for efficient shielding, a thi**ess of 0.0001 to 0.0005 inch being appropriate normally. Although the i**ion is to not be understood as so restricted, most **ductor cables for which shielding is required will employ **ductors from 0.040 to 0.075 inch in width and from 0.003 to 0.005 inch in thi**ess, with a spa**g between **ductors from 0.010 to 0.050 inch. The current i**ion is designed to permit repetitive interco**ion between a flat cable and an electrical co**or such as a co**or employed in a**ernal enviro**.



The co**or is mounted to a**ernal surface of an electrical gadget such that the header aspect of the housing initiatives outwardly to offer external electrical co**ion to the pin parts of the terminals. The terminals are mounted inside respective slits of the insulative housing such that the pin parts protrude via the apertures of the header facet and the **tact arms kind generally parallel rows of upper and decrease **tact arms on the tail aspect. Perpendicularly crossing the longitudinal slot sixteen are a series of parallel slits 17. The slits 17 are sized to obtain the terminals 12. Extending from the header facet 15 of the housing 11 are a sequence of apertures 18 arranged typically in two parallel rows. Another and more specific object of the present i**ion is to offer a flat cable and a co**or using such a flat cable whereby prevalence of crosstalk within the flat cable is minimized, even within the case that the co**or is designed according to a pin project by which certainly one of the 2 rows of pins of the co**or is used **pletely for carrying alerts.



Thus, the co**or supplied at an end of such a flat cable additionally has a pin assig** such that the pins for the sign cables and the pins for the facility cables are disposed alternately. The unshielded cable having the **ductors embedded in insulating material might be ready by previously identified methods similar to a lamination process whereby the **ductors and the top and backside insulating movies are fed from spools by way of a heated roller, the insulating films having utilized to the mating surfaces thereof an adhesive of the sort described above. So as to produce an acceptable bond between the insulating layers thirteen and 14 and the shielding metallic 15 the outer surfaces of the insulating layers are subjected to a surface roughening or etching treatment. For straight electrical co**ion, the terminals are shaped such that the **tact arms extend in an reverse course as the pin portion and the header side and the tail facet of the insulative housing are on opposite generally parallel surfaces. The terminals embody solder tails which lengthen out of the co**or housing which are soldered to a printed circuit board.



In accordance with o**ype of the current i**ion a low i**ion pressure multi-pin co**or for a flat versatile cable typically **sists of an elongate insulative housing, a plurality of **ductive terminals mounted within the housing and an insulative slide member. FIG. 1 is a perspective view of a prior artwork multi-pin co**or for a flat versatile cable. Co**ional round **ductor cable or cable of **paratively flat cross part having round **ductors embedded therein may be shielded by this implies. Any adhesive having a low dielectric **stant and the capability for bonding the insulation movie material to itself and to the **ductors ** be utilized. This result's readily obtained by slitting or chopping the insulation away from the edge of one or each of the outermost **ductors. The **tact obtained by exposing only the skinny edge of the **ductor is very efficient and dependable. FIG. 5 reveals an embodiment which is identical as that proven in FIG. 1 besides that the shielding layer 15 is pe**rated by a plurality of openings 68. The openings will be obtained by printing the desired pattern on the shielding layer 15 with standard photoresist material and etching to take away the metallic. The metallic shielding layer 15 is applied to the tough-surfaced flat cable by a two-step process together with electroless and electrolytic plating.
