[0001] The present application for a Patent of Invention consists, as indicated in its title,
in a "METHOD FOR THE INDIVIDUAL PROTECTION OF THE SMALL STAPLES IN A FLAT CABLE",
which novel characteristics of manufacturing, shaping and design fullfill the object
for which had been specifically designed with a maximum of safety and efficiency.
[0002] More particularly, the invention relates to plastic covers whose function is that
of covering the interconnection zone copper-copper between two or more FFC cables,
also called flat cables, formed with two insulating sheets between them are provided
a plurality of flat copper, aluminium or similar electric leads, arrangeded longitudinally
and parallel between them.
[0003] One of the covers is provided with a catch at the end of a tongue in every vertex
entering in its corresponding hole provided in the cover opposite, keeping both covers
joined and allowing the passage of the copper lines interconnected throgh the intermediate
zone of both covers.
[0004] A further object of the present invention is such that when because of the technical
requirements its necessary that the protection must be watertight, the covers will
incorporate silicone or HOT-MELT, thus the welding zones of the flat cables are protected
at the 100% by heating.
[0005] There exist in the market and therefore can be considered the state of the art a
plurality of flat cables which instead of having the traditional round shape are planes
practically laminar and contain a plurality of copper, aluminium or similar leads,
also flat, duly spaced with sheets of dielectric material welded in correspondence
to said leads. At the ends of said leads are dispoed the corresponding terminals,
staples and similar elements, being of special application in the automotive sector
and in grace to its special characteristics and as it s disclosed in the invention
number 9 802 629 to same applicant, allow its multirectional interconnection in grace
to a new welding method allowing to avoid the staples which served for keeping the
contact between the several leads and its substitution for the method proposed in
said patent, which basically allows the union between the conductive parts after having
eliminated or peeled the connection points of the dielectric or insulating material
covering same.
[0006] The present invention complementary to the above one of same applicant has the object,
as it has been disclosed above, for a second pass in the installations using said
type of cables, either if same are connected orthogonally with other of same nature,
or if same are connected at any type of direction, protecting said union and avoiding
that same may be a weak point of the general electric installation of the automobile,
not so much because of the possibility of undesired actions, as the humidity presence,
water vertical falling and other type of harmful effects, but also as an element serving
to reinforce the welding and avoiding that, at the moment of the assembly, and because
of the strain of one of the cables integrating the net or on the welding, may provoke
damages on same, which would be manifest once all the wiring of which said cables
are a part would be fully assembled, which would cause the corresponding damages,
not only because of the substitution of the defective material, but also because of
the need to double the assembly times.
[0007] Other details and characteristics of the present application for a Patent of Invention
will be manifest through the reading of the description given herebelow, in which
reference is made to the figures attached to this description where the above details
are depicted in a rather schematic way. These details are given as an example, referring
to a case of a possible practical embodiment, but is not limited to the details outlined;
therefore this description must be considered from an illustrative point of view and
with no limitations whatsoever.
[0008] There follows a detailed report of the several elements named in the present application:
(10) cable s union, (11) flat cable, (12) flat cable, (13) flat leads, (14) flat leads,
(15) insulating sheet, (16) insulating sheet, (17-18-19-20) welding zone, (21) protector,
(22) cover, (23) cover, (24) tongue, (241.1) catch, (25) holes.
[0009] Figure 1 is a perspective view of a crossing of flat cables (11 and 12) which had
been joined by the corresponding welding zones (17-18-19-20).
[0010] Figure 2 is a perspective view of the union of cables (10) protected by its protector
(21) formed by the covers (21 and 22).
[0011] Figue 3 is a perspective view of the protector (21), covering the union zone of the
flat cables (11 and 12).
[0012] In one de preferred embodiments of what is the object of the present application
for a Patent of Invention and as can be seen in Figure 1, the flat cables (11 and
12) are formed with protecting sheets (16) of a dielectric material covering with
insulation the coper, aluminium or similar material leads (13 and 14) parallel between
them and longitudinally arranged. When same must interconnect, and by the method disclosed
in the Patent of Invention No. 9 802 629, it is carried out the connection of same,
remaining electrically joined by the welding zones (17-18-19-20).
[0013] When the union of cables above described, which can be seen in Figure No. 1, needs
a standard protection, it is covered with what is the object of the present Model
of Utility: the protector (21) formed with two covers of a noticeably cuadrangular
section, provided with the corresponding holes (25) in the neibourghood of their vertexs,
by which there are introduced tongues (24) provided in the other cover, entering through
said holes and immobilizing said covers (22 and 23) of the protector (21) in grace
to being provided in the ends of said tongues of catches or spurs (24.1), therefore
remining said welding zones duly protected, see Figures No. 2 and 3.
[0014] Additionally, a further object of the present invention is obtaining a full watertightnes
of the union and welding zones, by the incorporation of silicone or HOT-MELT and a
further heating.
[0015] In this way, the welding zones (17-18-19-20) remain duly protected.
[0016] Enough disclosed what the present application for a Patent of Invention is in agreement
with the attached figures, it s understood that can be introduced in same any detail
modifications regarded as convenient, always provided that any the modifications entered
do not depart from the essence of the present Patent of Invention as summarized in
the following claims.

(17-18-19-20) which connect electrically and in a selective way the leads (13 and
14), in grace to being previously obtained such welding zones by the removal or peeling
of the sheets in said zones, proceeding afterwards to the welding of the exposed conductive
zones (13 and 14) by the application of an ultrasonic or similar welding method, characterized
