Abstract

A printed circuit board comprises a substrate (1) of an electrically insulating material, a plurality of electrical current carrying paths (2) of electrically conductive material on the substrate and a plurality of integrally formed insulation displacement connectors (4) connected to the paths. The connectors may be edge connectors, or connectors within the periphery of the board or a combination of both. An edge connector is formed with a slot (5) which may be at an angle to the plane of the board. A connector within the periphery of the board comprises a larger diameter portion leading to a slot and means for pushing an insulated conductor inserted in the larger diameter portion into the slot. This arrangement results in fewer components to assemble, higher frequency performance, reduced cross-talk, space savings and lower costs.

Description

A PRINTED CIRCUIT BOARD
The present invention relates to a printed circuit board.
Wherever there is a requirement to connect an insulated wire or wires to an assembly, with ease, speed and a minimum of tooling, there is often
an Insulation Displacement Connector (IDC) used. An insulated wire is
forced into some form of slot in a conductive material, the width of the slot
being somewhat less than the overall thickness of the insulated wire. The
insulation is broken and the inner conductor of the wire makes electrical
contact with the conductive material. There is often some form of grip to
the cable to prevent it coming out of the slot. This type of connector is
utilised in a wide variety of industries across the world.
There is a multitude of differing formats of insulation displacing
connector for connecting insulated wire to a printed circuit board (PCB).
However, all are fabricated as a discrete connector which is subsequently
attached (soldered, screwed, push-fit etc.) to a PCB which again is a
discrete item fabricated totally separately to the IDC.
According to the present invention, there is provided a printed circuit
board comprising a substrate of an electrically insulating material, an
electrical current carrying path of electrically conductive material on the
substrate and an insulation displacement connector forming an integral part
of the board and electrically connected to the path of electrically conductive material.
The insulation displacement connector may be formed at the edge of
the board or it may be formed within the periphery. The edge connector
comprises a slot extending from the edge of the board. The slot may be at
an angle to the plane of the board. The connector within the periphery may
comprise an aperture. The aperture may have a shape comprising a portion
of larger diameter to receive an insulated conductor. Means are provided for pushing an insulated conductor inserted in the circular portion into the slot
portion of the connector.
The interior of the slot or aperture may be coated with a hard
electrically conductive material. This material may be nickel. A plurality of
connectors may be provided either at the edge of the board or within the
periphery or both and a number of electrically conductive paths connected
to these connectors.
In order that the invention be more clearly understood, embodiments
thereof will now be described, by way of example, with reference to the
accompanying drawings, in which:-
Figure 1 is a plan view of part of a printed circuit board,
Figure 2 is a side elevational view of the part of the board of figure 1 ,
Figure 2a is a detail view to a larger scale of part of the board of figure Figure 3 is a side elevational view as per figure 2, but showing an insulated conductor in the terminated position.
Figure 4 is a perspective view of another embodiment of the invention,
Figure 5 is an end elevational view of the embodiment of figure 4,
Figure 6 is a detailed view of part of the embodiment of figures 4 and
5, and
Figure 7 is a further detail view in section to an enlarged scale along the
line X-X of Figure 6 of part of the embodiment of figures 4 and
5.
Referring to figures 1 to 3, the printed circuit board comprises a
substrate 1 of an insulating material. In this particular example, the
substrate is a 0.4mm thick resin bonded glass fibre laminate, but boards of other thicknesses and of other materials may be used as required. Paths 2
of electrically conductive material such as copper are formed on the
substrate usually by etching from complete conductive material layers. Each
path terminates in an edge connector at the edge 3 of the board. Each edge
connector is formed as an insulation displacement connector (IDC). In this
particular example, four paths 2 are shown.
Each insulation displacement connector 4 comprises a slot 5 coated
on its internal surface with a hard electrically conductive material 6 such as
nickel. The width of each slot is chosen to be slightly less than the diameter of the conductor of the insulated conductor which is to be connected to the
connector. In this way, as the insulated conductor is pushed into the slot
the interior surface of the slot cuts into and displaces the insulation 9
around the conductor 10 thus enabling the electrical contact to be made
between the conductor and the connector. To facilitate cutting each
insulated conductor may be pushed into the slot at an angle other than vertical to the plane of the board 1. The angle may be chosen as desired but
in this example is about 60° to the plane of the board. The upper and lower
edges 7 and 8 of the angled slots(only one slot referenced for simplicity)
present sharp cutting edges to the insulation of an insulated conductor.
Each conductor adopts a slightly zig-zag path through the board 1.
Integral insulation displacement connectors may also be formed inside
the periphery of the printed circuit board rather than at its edge. Such an
arrangement is shown in figures 4 to 7. Referring to these figures and in
particular to figures 4 and 5, a printed circuit board 20 is supported in a
moulded plastic housing 1 1 which also forms a socket assembly 12 for a
telephone line connector. The printed circuit board is of a similar basic
construction to that already described in the first embodiment (figures 1 and
2) having a substrate of an electrically insulating material such as resin
bonded glass fibre laminate and electrically conductive paths for example
of copper on both faces. In contrast to the embodiment of figures 1 and 2, the substrate is formed with six apertures 13 each having a keyhole shape
as shown in figure 6 and in section in figure 7 comprising a substantially
circular portion 14 connected to a narrow slot like portion 15. A slidable
plastic cover 16 locates" over the printed circuit board. This has six
apertures 17 which coincide with the six apertures 13 in the printed circuit
board 20. The conductive paths, which are obscured by this cover 16, are
electrically connected to respective apertures 13 which are internally coated
at 18 with an electrically conductive material such as nickel as shown in
figure 7. This coating 18 extends onto both surfaces of the board 20 as
shown at 19 to maximise the conductor area for contacting the conductor inserted therein and to provide for efficient connection to respective
conductive paths.
In operation, after placing the six insulated conductors in the circular
portions 14 of the corresponding apertures 13 in the printed circuit board
20, the slidable plastic cover 16 is slid over the board 20 thus
simultaneously pushing the six insulated conductors into the narrow slot-like
portions 15. The diameter of the circular portions 15 is greater than that of
the insulated conductors and the width of the slot-like portions is less than
the diameter of the conductor itself. Thus on being pushed into these slot-
like portions 15, the insulation is cut and displaced by the hard inside
surfaces of the surfaces of the portions 15 to make electrical contact with the conductors.
The above described arrangements enable external wires to be
connected to a printed circuit board without the need of any intermediate
device. This results in fewer components to assemble, higher frequency
performance, reduced cross-talk, space savings and lower costs.
It will be appreciated that the above embodiment has been described
by way of example only and that too many variations are possible without
departing from the scope of the invention.
