Claims
What is claimed is:
1. An electrical fusing arrangement comprising a first member
formed of an electrically insulating material to which may be
secured the ends of two flat cables with the conductive tracks on
one of said cables being aligned with the conductive tracks on the
other of said cables, a second generally flat member of insulating
material having on at least one of its faces electrically
conductive fuse tracks each having a reduced width region
functioning as a fuse, said fuse tracks extending in parallel
relationship between opposite sides of said second member and being
electrically isolated from each other, said second member being
fitted to said first member such that each of said fuse tracks
bridges the gap between the conductive tracks on said flat cables,
and latch means for rapidly, releasably fastening said first and
said second members together.
2. An arrangement as recited in claim 1 wherein said first member
has a flat rectangular surface with an upstanding pillar at each
corner, each said pillar having a slot at its base where it meets
said flat surface, and said flat cables being adapted to be each
secured to said first member by having their edges held in said
slots.
3. An arrangement as recited in claim 2 wherein said second member
is a board of insulating material carrying said fuse tracks
supported by a backing strip, and said second member is formed with
hook-ended latches at two opposed edges thereof normal to said
opposite sides and forming said latch means, said hook-ended
latches, when said second member is positioned on said first
member, each passing between two of said pillars and engaging the
surface of said first member opposite to said flat rectangular
surface.
4. An arrangement as recited in claim 3 wherein a fuse
track-carrying backinng strip is mounted on each face of said
board, and two pairs of said hook-ended latches are formed on said
second member.
5. An arrangement as recited in claim 1 including spring means on

7. An arrangement as recited in claim 1 wherein said fuse tracks
are provided on opposite faces of said second member.
Description
BACKGROUND OF THE INVENTION
This invention relates to the electrical connector art and, more
particularly, to an assembly for connecting two different flat
cables.
In the past, it has been difficult and expensive to connect two
pieces of flat cable together.
SUMMARY OF THE INVENTION
In accordance with the device of the present invention, the
above-described and other disadvantages of the prior art are
overcome by providing a connecting strip of conductors which are
held in contact with corresponding conductive strips of two
different flat cables.
The above-described and other advantages of the present invention
will be better understood from the following detailed description
when considered in connection with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a mounting board with two
connecting strips thereon;
FIG. 2 is a perspective view of two flat cables assembled for
connection;
FIG. 3 is a longitudinal sectional view taken on the line 3--3
shown in FIG. 2;
FIG. 4 is a perspective view of another connecting strip mounting
board;
FIG. 5 is perspective view similar to that shown in FIG. 2; and
FIG. 6 is a transverse sectional view taken on the line 6--6 of the
structures shown in FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the drawings in FIG. 1, a mounting board is indicated at 10
having connecting strips 11 and 12 fixed thereto between
corresponding shoulders 13 and 14 of clips 15 and 16. Clips 15 and
16 are removably mounted to the board 10 and strips 11 and 12 but
clip the strips 11 and 12 tightly enough to hold them in place as
shown in FIG. 1. That is, all the structures shown in FIG. 1 will
stay together without assistance.
Strip 12 may be identical to strip 11 is desired. Strip 11 includes
a layer 17 of an insulating material having conductive strips 18
thereon. Strips 18 have fuse portions 19.
The assembly of FIG. 1 may be employed with the apparatus shown in
FIG. 2 including a base 20 that has four posts 21 fixed thereto.
Posts 21 support base 20.
As shown in FIG. 3, base 20 includes a channel-shaped member 22 and
a flat plate or platform 23 covering the upper opening thereof.
Springs 24 normally urge platform 23 to a position spaced from the
upper edges of base 20.
As shown in FIG. 3, flat cables 25 and 26 terminate at 27 and 28
respectively on top of platform 23. Board 10 is mounted over cables
25 and 26 as shown in FIG. 3. One end of each of the conductive
strips 18 lies in contact, for example, with one end of a
corresponding conductor in cable 15. Layer 17 is so indicated in
FIG. 3. The same is true of connecting strip 12. Clip 15 is also
shown in FIG. 3.
In addition to the foregoing, the other end of each strip 18 lies
in pressure and electrical contact, as before, with a corresponding
conductor in cable 26.
From the foregoing, it will be appreciated that either connecting
strip 11 or connecting strip 12 may be placed in engagement with
cables 25 and 26.
In FIG. 2, cables 25 and 26 are shown with conductive strips 29 and
30 fixed to insulation layers 31 and 32 respectively. End portions
A and B of the conductors 30 and 29 are those portions which may be
engaged by corresponding end portions of strips 18.
In FIG. 1, note will be taken that clips 15 and 16 have projections
33 and 34 which can snap under a shoulder 35 at each end of base
20, as shown in FIG. 2.
An alternative embodiment of the invention is shown in FIGS. 4, 5
and 6. In FIG. 4, a mounting board is shown at 36. A board 37
integral with clips 38 and 39 hold a connecting strip 40 on board
36. Thus, board 37 and clips 38 and 39 are demountable from board
36. Board 36 may be assembled to the apparatus shown in FIG. 5 in a
manner similar to the manner in which board 10 is assembled to the
apparatus shown in FIG. 2. As before, clips 38 and 39 have
projections 41 and 42, respectively, which can snap under a ledge
43 of a base 44.
As shown in FIG. 6, base 44 includes a channel-shaped housing 45
having projections 46 and 47 therein. A cable 48 is threaded over
channel 45 into the space between projection 46 and a channel side
panel 49. Similarly, a cable 50 is threaded over the channel 45
into the space between projection 47 and a channel side panel 51. A
spring 52 is located between cable 50 and channel side panel
51.
As shown in FIG. 4, strip 40 has holes 53 therethrough. Board 36
then has recesses 54 that lie in registration with holes 53. The
recesses 54 are provided to accommodate dowels 55 fixed to the
bottom panel 56 of channel 45 as shown in FIGS. 5 and 6.
As shown in FIG. 4, strip 40 includes a layer of insulation 57 with
conductive strips 58 thereon including fuse portions 59. One end of
each of the conductive strips 58 lie in engagement with a
corresponding one conductor in cable 48. The other end of each of
the conductive strips 58 lies in engagement with a corresponding
conductor in cable 50.
If desired, bases 20 and 44 and other structures disclosed herein
may be made out of insulating material such as a molded plastic. If
desired, the apparatus shown in FIG. 5 may have posts 21' identical
to the posts 20 shown in FIG. 2. In both cases, if desired, each of
the posts 21 and 21' may be provided with a slot, particularly if
it is desired that the same accommodate platform 23.
If desired, cables 25 and 26 may be fitted into the slots of posts
21 as shown in FIG. 2.
If desired, the cables 25 and 26 may be secured to platform 23 by
glue.
Note will be taken that board 10, if desired, may be substantially
more rigid than cables 25 or 26 or substantially more rigid than
connecting strips 11 or 12.
If springs 24 are employed, they may be used to insure adequate
contact pressure.
When one or more fuses blow, board 10 may be removed, the fault
cleared and the board replaced inverted, if desired. After two
fuses have blown, the board 10 may be discarded. This is true
because the complete assembly of FIG. 1 may be made very
inexpensively.
In the FIG. 4, a one-sided arrangement has been disclosed. However,
this also could be a two-sided arrangement.
In accordance with the present invention, it is also shown that the
strips 18 and 58 can be replaceable on the corresponding insulating
layers 17 and 57 if desired. In this case, the replacements of the
entire assembly of FIGS. 1 and 4 need not be made.
