Utilizing 7 Flat Cable Methods Like The pros

Still one other object of this invention is to supply a coaxial flat tape cable which incorporates an electrical shield that will move relative to the tape cable thereby increasing the flexibility of the cable. In addition the area having no adhesive could retain small air pockets which promote corrosion and delamination, especially at excessive temperature and in vacuum. An basically rectangular recess 103 is molded into the mounting part, and in the bottom space of the recess 103 is supplied a rectangular passage opening 104 which ends up in the inside house of the housing. At the ends, the clamps are provided with bores 32, 33 for head-to-head bolting beneath inclusion of the posts 14 of the mounting part, whereby in one of the clamps, there are offered bolt holes 33 and tapholes 32 in the opposite clamp. However, in that case, the tensile stress relief clamps must be configured such that their undersides press in opposition to the seal when threaded to the posts of the mounting part.

The undersides of the clamps can thereby moreover be provided with a cleat-formed extension which is similar to the roll-shaped rim of the stress plate. On the housing side dealing with the mounting part, a connector insert may be mounted within the housing, which isn't shown intimately. The outer measurements thereof correspond to the measurements of the groove 22 of the mounting half, and the thickness of the seal corresponds approximately to the depth of this groove. The outer measurements of these disks correspond to the geometry of the recess 103 of the mounting half. The seal corresponds in its outer measurements to the dimensions of the recess 103, and is supplied with a rectangular heart slit 122 corresponding to the cross-sectional form of the flat cable. The measurements of this passage opening are smaller than the recess 103, so that it varieties borderside enclosing shoulders 105. On two reverse sides of the mounting half are provided perpendicular posts 106 on which the tensile stress relief clamps, which will probably be described below, could be fastened.

FIG. Four exhibits varied views of a mounting part 1. The mounting half primarily consists of a body-formed base half 21 which is provided with two posts 14 on the two opposite sides. In FIGS. 9 to eleven are shown various views of an alterate connector housing 101. On the higher aspect of the housing is offered a body-shaped mounting part 102 which is made in one piece with the housing. Next to the opening, there are offered passage openings 20 for the bolt fastening of the mounting half 1. The remainder of the connector housing corresponds to a housing identified in regular industrial usage, during which a connector insert (not proven in detail) can be inserted from the course of the bottom side. The disks are provided with a centered opening corresponding to the cross-sectional dimensions of the inserted flat cable 109. The flat cable is guided by way of the slit 122 of the seal, as nicely because the opening 128 of the disks and extends by means of the passage opening 104 into the inside of the housing. 12 and 13, which present how a flat cable 109 is inserted into the housing a hundred and one and held in place in order that it is freed from tensile stress.

The pressure plate is provided with a rectangular opening 30, which can also be adapted to the flat cable to be inserted. Similarly, U.S. Pat. No. 4,640,562 to Shoemaker discloses a floor mounting means for an electrical connector to a printed circuit board which includes a wedge plate for forcing contact of the flexible cable to the terminals of the connector. The terminals embrace solder tails which lengthen out of the connector housing which are soldered to a printed circuit board. Use of low insertion force (LIF) and zero insertion drive (ZIF) connectors on printed circuit boards for receiving a flexible printed circuit (FPC) or a versatile flat cable (FFC) is well known in the sector. The utilization of the flat cable entry according to the invention is feasible on all flat housings or wall surfaces. It can also be provided that two, or in a given case, also many flat cables are entered superposed into the cable entry, whereby, in this case, adapted seals and strain plates are also used, whereby likewise a sealing of the entry location is attained in that the seal is pressed in opposition to the outer cable, and that the cables are pressed towards each other. The opening is surrounded by an enclosing, roll-formed rim 13, which presses in opposition to the seal 2 when the cable entry is joined collectively.
