Abstract
A composite connector for use with a perforated circuit board is formed from a preform of electrically conductive sheet metal which is folded to form, at one end of the composite connector, a socket 1 which will make a snap fit in a hole in a circuit board and in which a terminal pin of a circuit component can be resiliently gripped and, at the other end of the composite connector, two bifurcated contacts 2. The bifurcated contacts 2 are transversely spaced apart and are of such a form that when a length of insulated wire is introduced between the limbs 7 of each bifurcated contact, the limbs will cut through the insulating covering of the wire to effect an electrical connection with the wire at two positions spaced along its length. <IMAGE>
Description
SPECIFICATION
An improved circuit board composite connector
This invention relates to circuit boards and, more particularly, to composite connectors for use with circuit boards.
One kind of circuit board that is in general use comprises a board of electrically insulating material, which board has bonded on one of its surfaces a regular pattern of strips of electrically conductive metal or metal alloy, usually but not necessarily copper, and has, extending through the board and the overlying electrically conductive metal strips, a multiplicity of holes distributed at spaced positions along the strips. Circuit boards of this kind will hereinafter, for convenience, be referred to as "a circuit board of the kind described.
In order to establish a required circuit using a circuit board of the kind described, it is the present practice to employ composite connectors, each comprising a socket and, integral with the socket, a wiring pillar. Each of a number of such composite connectors is inserted into a selected hole in the circuit board so that the socket is a snap fit in the hole and the wiring pillar upstands from that surface of the board to which the metal strips are bonded. Terminal pins of circuit components are introduced into and are resiliently gripped in selected sockets of the composite connectors from the surface of the circuit board remote from the metal strips, and the components of the circuit are electrically interconnected, as required, by wrapping wire tightly around selected wiring pillars of the composite connectors.Each wiring pillar is of rectangular cross-section and wire is wrapped around a pillar using a wrapping tool under a sufficient tension to ensure that the sharp edges of the pillar cut into the wire to effect satisfactory electrical contact. Selected pillars of the composite a connectors are usually solder to parts of the circuit board to provide for electrical connection to supply voltages or earth.
It is an object of the present invention to provide for use with a circuit board of the kind described, an improved composite connector by means of which a desired circuit can be established more rapidly and simply than when using composite connectors hitherto employed.
According to the invention, the composite connector is formed from a preform of electrically conductive sheet metal or metal alloy, e.g. copper, which is folded or otherwise shaped to form, at one end of the composite connector, a socket which will make a snap fit in a hole in a circuit board of the kind described and in which a terminal pin of a circuit component can be resiliently gripped and, at the other end of the composite connector, at least two bifurcated contacts which are transversely spaced apart and which are of such a form that when a length of insulated wire is introduced between the limbs of each bifurcated contact, the limbs will cut through the insulating covering of the wire to effect an
electrical connection with the wire at at least two
positions spaced along its length.
Preferably, the end of the composite connector
remote from the socket is of substantially tubular
form with two bifurcated contacts positioned at
substantially diametrically opposed positions and
with the slots bounded by the limbs of the
bifurcated contacts opening into that end of the
composite connector. In a preferred embodiment,
the axes of the slots bounded by the limbs of the
bifurcated contacts and the axis of the composite
connector itself lie in a common plant. The radially
inner and outer surfaces of the limbs of the
bifurcated contacts are preferably substantially flat
and, also, preferably lie in planes substantially
normal to the common plan in which lie the axes
of the slots of the bifurcated contact.The corners
of each limb of each bifurcated contact are
preferably radiused to reduce substantially the risk
that these corners might otherwise cut into, and
seriously weaken, a wire.
To limit the extent to which a terminal pir. of a
circuit component can be introduced into the
socket, preferably a part of the perform is folded or
otherwise shaped to extend radially inwardly of
the socket to form a stop. This stop may take the
form of a tongue folded radially inwardly from a
window in the wall of the substantially tubular end
of the composite connector remote from the
socket; this tongue may also be so positioned as
to serve as a stop limiting the extent to which a
length of insulated wire can be introduced into the
slots of the two bifurcated contacts.
Resilient gripping of a terminal pin of a circuit
component within the socket of the composite
connector is preferably effected by a separately
formed socket contact of electrically conductive
metal or metal alloy e.g. gold-plated copper, which
is a tight fit in the socket of the connector but, in
some circumstances, means for resiliently gripping
a terminal pin of a circuit component when
introduced into the socket of the composite
connector may be an integral part or of the wall of
the socket.
Preferably, the composite connector is formed
between its ends with an outwardly extending shoulder to limit the extent to which the connector
can be introduced into a hole in a circuit board of
the kind described.
The improved composite connector of the
present invention has several important
advantages over composite connectors hitherto
proposed and used on circuit boards of the kind
described. Firstly, the improved composite
connector can be readily formed from a sheet
metal blank and can be assembled on a circuit
board using a simple hand tool or automatically
from a bandolier of composite connectors.
Secondly, no skill is required in electrically
connecting a length of insulated wire to the
composite connector and the feature of effecting
electric contact at spaced positions along the wire
provides for a reliable electrical connection. The
necessity to strip insulation from an insulated wire
is eliminated and electrical connection of an insulated wire to the composite connector can be effected more rapidly and simply than has hitherto been possible. Furthermore, when required two separate lengths of insulated wire can be introduced as one after the other into the slots of the bifurcated contacts of the improved composite connector.Since a wiring pillar is no longer employed, a circuit board of the kind described on which is assembled a circuit employing improved composite connectors of the present invention will be substantially thinner than a circuit board on which is assembled a circuit employing composit connectors having wiring pillars extending from one face of the board and, consequently, where the board is to be mounted in a cabinet or racking, there is a substantial saving of valuable space.
The invention is further illustrated by a description, by way of example, of a preferred composite connector with reference to the accompanying drawings, in which: Figure 1 is a side elevation of the preferred composite connector drawn on a greatly enlarged scale;
Figure 2 is a side elevation of the composite connector shown in Figure 1 taken at an angle of 900 to the side elevation shown in Figure 1, and
Figure 3 is a view from above of the composite connector shown in Figure 1.
Referring to the drawings, the composite connector is formed by folding a sheet copper blank into generally tubular form and comprises, at one end of the connector, a socket 1 for insertion into a hole in a circuit board of the kind described and, at the other end of the connector, two bifurcated contacts 2 at diametrically opposed positions around the connector. The socket 1 has at least one outwardly projecting dimple 3 for effecting a snap fit in a hole in a circuit board and, between the socket and the bifurcated contacts 2, the connector has an outwardly extending shoulder 4 for limiting the extent to which the connector can be inserted into a hole in a circuit board. Tightly fitting within the socket 1 is a separately formed gold-plated copper socket contact 5 for resiliently gripping a pin of a circuit component.
The axes of the bifurcated contacts 2 and the axis of the connector itself lie in a common plane.
The limbs 7 of each bifurcated contact 2 define a slot 8 for reception of a length of insulated wire and have flat radially inner and outer surfaces that lie in planes normal to the common plane in which lie the axes of the bifurcated contacts 2. The corners of the limbs 7 of each bifurcated contact 2 are radiused at 9. At the open end of each bifurcated contact 2, parts of the limbs 7 are removed to provide a throat 12 to facilitate introduction of a length of insulated wire into the slot 8. In the wall of the tubular portion of the connector remote from the socket 1, is a window
10 from which Is radially inwardly folded a tongue 11 constituting a stop limiting the extent to which a pin of a circuit component can be inserted into the socket.
