Description
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention relates generally to a multi-point connector
arrangement, and more particularly to such an arrangement for
effecting positive mating relation between a plug having a
plurality of connector projections thereon and a receptacle adapted
to selectively receive each of the connector projections.
2. Description of Prior Art
It has been a problem when mating conventional male and female
elements of a pin type connector to ensure proper alignment of the
respective housing portions prior to actual mating of the male and
female pin connectors. It can readily be understood that if the
respective housing portions supporting the male pins and female
receptacles are not aligned, proper contact of the pins cannot be
assured; and of equal importance, the force used in attempting
mating of the non-aligned elements may damage them.
It has also been a problem in multi-point connectors to ensure
positive contact of all of the male pins with their corresponding
female receptacles. Conventional multi-point connectors employ
separable housing members which are secured at mating edge portions
such that the force required to mate the pins and receptacles is
usually applied at the edges of the housings and not in their
centers. Accordingly, the pins along the edges of the housing
members are ensured of positive contact, while those pins centrally
located may not be properly received in positive contact with the
corresponding receptacles.
SUMMARY OF THE INVENTION
The present invention seeks to overcome the problems associated
with the prior art multi-point connectors by providing on one of a
pair of housing members supporting male pins and female receptacles
to be positively mated, a pair of laterally spaced locating member
means adapted to hingedly engage a pivot rod supported by the other
of the housing members. An alignment tongue is secured to the
housing member supporting the pivot rod and serves to engage a
cross plate fixed to the locating member means to urge the pivot
rod into firm engagement with the locating member means to ensure
proper alignment of the male and female elements of the connector
prior to effecting actual contact therebetween. The housing members
include frame bars which are cambered, when considered in side
profile, to effect a biased engagement of the centrally disposed
connector pins with their associated receptacles when the housing
members are brought into positive interconnection.
Accordingly, one of the primary objects of the present invention is
to provide a multi-point pin type connector which includes novel
means insuring proper alignment of the pins with their
corresponding receptacles before mating is effected.
Another object of the present invention is to provide a multi-point
connector including novel means to ensure positive contact between
all the male pin elements and their corresponding female
receptacles of the connector, both those along the edge of the
housing members and those disposed centrally thereof.
Another object of the present invention is to provide a multi-point
connector as described wherein the means for insuring proper
alignment of the connector pins and associated receptacles includes
locating members adapted to engage a pivot rod, and an alignment
tongue adapted to engage a cross plate in order to urge the pivot
rod into positive engagement with the locating member.
According to one feature of the invention the novel connector
device of the present disclosure finds useful application in
effecting the connection of programs to the control circuitry of
associated machinery to which the female receptacle of the
connector may be fixedly attached. In one embodiment, a different
male plug is provided for each different program to be used, and in
reprogramming the associated machinery, it is only necessary to use
the particular one of the male connectors which has the desired
program.
Further objects and advantages of the present invention, together
with the organization and manner of operation thereof, may best be
understood by reference to the following description of a preferred
embodiment of the invention when taken in conjunction with the
accompanying drawings.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings, and in particular to FIGS. 1a and
1b, there is illustrated a female receptacle connector member,
indicated generally at 100, and a plug or male connector member
indicated generally at 101. The female connector member 100
includes a housing structure comprising a pair of parallel
laterally spaced frame bars 10 and 12. Secured along the rearward
surface of each frame bar 10 and 12 are individual forty pin female
receptacles 14, 16, each receptacle having two 20 pin sections 14a,
14b; 16a, 16b, each pin section extending outwardly on opposite
sides of the frame bars 10 and 12. A number of such receptacle
sections may be secured longitudinally along the frame bars 10 and
12 depending upon the number of pin connections desired between the
female and male connector members 100 and 101.
The male connector member 101 is of the same general size as the
female connector member 100 and similarly includes a housing
structure comprising parallel laterally spaced frame bars 18 and
20. The frame bars 18 and 20 support a plurality of male plugs,
each plug having two pin sections 22a, b; 23a, b, in similar
fashion to the mounting of the female receptacles 14 and 16 on the
frame bars 10 and 12. The housing structure of the male connector
member 101 includes a casing 24 which serves to enclose a wired
electrical program, or electrical cable, associated with the male
plugs. The casing 24 has an upper end plate 26 which is generally
coplanar with the upper ends of the spaced frame bars 18 and 20. As
will become more apparent hereinbelow, the male pins on the male
plug sections 22a and b, 23a and b of the male connector member 101
are adapted to be received and connectively coupled to the female
receptacle sections 14a and b, 16a and b of the female connector
member 100. The present invention insures proper registration of
the male plugs and female receptacles and insures positive contact
therebetween during coupling or connection of the male and female
connector members.
The male connector member 101 includes alignment mechanism means,
indicated generally at 28, secured to the upper end plate 26 of the
casing 24. The alignment mechanism means 28 serves both as a means
by which the female connector member 100 can be hingedly connected
to the male connector 101, and a means cooperative with the female
connector member to insure proper alignment of the male plugs and
female receptacles during coupling. The alignment means 28
comprises a bracket 30 having a planar base portion 32 and parallel
upstanding end flanges 34 and 36. The base portion 32 is secured to
the upper end plate 26 of casing 24 by screws 37. The end flanges
34 and 36 support a pivot pin or rod 38 disposed perpendicular to
the longitudinal axes of the upper ends of the frame bars 18 and 20
lying in a plane parallel to and spaced outwardly from the forward
surfaces of the frame bars 18 and 20 as shown in FIG. 2c.
The alignment mechanism means 28 includes an alignment tongue 40
having a rearward portion 42, suitably secured to the base portion
32 of bracket 30 by screws 43, and a forward portion 44 lying in a
plane inclined upwardly relative to the rearward portion 42. The
upward inclination of portion 44 is from a bend line 45 disposed
rearwardly of the alignment rod 38 as will become more apparent
hereinbelow.
The female receptacle connector member 100 includes locating means,
indicated generally at 46, adapted for cooperation with the pivot
rod 38 to effect a hinge connection between the female connector
member and the male connector member 101. The locating means 46
includes a pair of laterally spaced locating members which
preferably comprise upper end portions of the frame bars 10 and 12
extending above the female receptacles 14, 16 as shown in FIG. 1a.
The spaced locating members have aligned transverse slots or
grooves 48 and 50 therein which are adapted to receive the
alignment rod 38 therein.
The upper ends of the spaced frame bars 10 and 12 comprising the
locating members of locating means 46 have a cross plate 52
suitably secured to the rearward surfaces thereof in transverse
relation to the longitudinal axes of the upper ends of the frame
bars 10 and 12. The cross plate 52 has a vertical dimension
extending from the upper ends of the frame bars 10 and 12
downwardly such that its lower edge is spaced vertically above the
upper end of the female receptacles 14, 16. The cross plate 52
preferably extends laterally outwardly from the frame bars 10 and
12 with its outer ends being provided with holes 54 for securing
the female connector member 100 to a suitable support frame before
the male connector 101 and the female connector 100 are connected
together as described below. A similar cross plate 51 is attached
to the other end of mounting bars 10 and 12 for use in attaching
the female connector 100 to the same support frame.
The lateral dimension of the forward portion 44 of the alignment
tongue 40 is such that the forward upwardly inclined portion of the
alignment tongue may be received between the laterally spaced frame
bars 10 and 12 of the female connector member 100 and between the
lower edge of the cross bar 52 and the upper edge of the female
receptacles 14, 16.
Noting FIGS. 2a-c, wherein end flange 34 of bracket 30 is broken
away for clarification, positioning of the male plug connector
member 101 approximately perpendicular to the plane of the female
connector member 100, FIG. 2a, allows the pivot rod 38 to be
readily received within the aligned grooves 48 and 50 of the
locating means 46. With the male connector member 101 positioned
with its pivot rod 38 received within the aligned grooves 48 and
50, the male connector member may be rotated downwardly with the
alignment tongue 40 being received between the cross plate 52 and
female receptacles 14, 16, FIG. 2b. As noted, the forward portion
44 of the alignment tongue 40 is inclined upwardly relative to the
upper end 26 of casing 24. The angle of upward inclination is
established to cause the upper surface of the forward portion of
the alignment tongue 40 to engage the lower edge surface of the
cross plate 52 and urge the male connector member 101 downwardly
such that the pivot rod 38 of the male connector member 101 is
firmly seated in the bottoms of the aligned grooves 48 and 50. The
pivot rod 38 is disposed forwardly of the associated frame bars 18
and 20 (FIG. 1b) and cooperates with the aligned grooves 48 and 50
(FIG. 1a) in the frame bars 10 and 12 to assist in the alignment of
the male projecting elements on the male plug sections 22a and b,
23a and b with the corresponding female receptacle sections 14a and
b, 16a and b of the female connector member 100 when the male and
female connector members are brought into mating relation.
FIGS. 3a-c illustrate schematically the side profile configurations
of the frame bars 10 and 12 of the female connector member 100 and
the frame bars 18 and 20 of the male connector member 101. The side
profile configurations of the pairs of frame bars are adapted to
effect a biased engagement of the centrally disposed connector pins
of the male plug sections 22a and b, 23a and b with the
corresponding female receptacle sections 14a and b, 16a and b when
the male and female connector members are brought into positive
interconnection. In the showing of FIG. 3a the male connector 101
has been properly engaged with the female connector 100 in the
manner shown in FIG. 2b, and has been moved in the direction of the
female connector 100 so that the upper pins of the two connectors
are in mating relation. Noting FIG. 3b, the lower one-half length
of each of the frame bars 10 and 12 of the female connector member
100 is cambered rearwardly from a bend line 55 disposed
approximately intermediate its length. Similarly, the frame bars 18
and 20 of the male connector member 101 are cambered rearwardly
from bend lines 56 disposed generally intermediate their lengths.
With the frame bars 10, 12, 18 and 20 having their lower half
lengths cambered rearwardly as shown in FIG. 3b, bringing the
respective frame bars of the male and female connector members 100
and 101 together such that they are in substantially full
contacting engagement along their mating surfaces as shown in FIG.
3c will effect the desired positive contact of the male pin
elements and female receptacle elements throughout the full length
of the multipoint connector arrangement. It has been found that
with the respective female and male connector members 100 and 101
having longitudinal lengths of approximately about 8.5 inches,
providing a rearward camber of one-sixteenth inch for the lower
half lengths of the frame bars 10 and 12, and a rearward camber of
approximately about one-eighth inch for the lower half lengths of
the frame bars 18 and 20 will provide the desired biased engagement
of the intermediate length portions of the frame bars.
Noting FIG. 4, the multi-point connector arrangement including the
female connector member 100 and male connector member 101 includes
means for maintaining the respective separable male and female
connector members in locked coupled relation. To this end, the
casing 24 of the male connector member 101 has a latch handle 58
secured to the rearward surface thereof, the latch handle being of
a known type commercially available from the Camloc Fastener
Corporation of Paramus, New Jersey. The latch handle 58 pivotally
supports a locking lever 60 having a lower hooked end portion 62.
The hooked end 62 of the locking lever 60, FIG. 4a, is adapted to
matingly interconnect with a hook end 64 provided on the forward
end of a catch bracket 66 which is affixed in generally normal
relation to the lower ends of the depending frame bars 10 and 12 of
the female connector member 100. It can be seen that when the male
connector member 101 is brought into mating engagement with the
female connector member 100, with the locking lever 60 in a
generally vertical position as considered in FIG. 4a, further
pivotal movement of the locking lever toward the vertical position
will cause the hooked portions 62 and 64 of the locking lever 60
and catch bracket 66, respectively to apply a force which urges the
pins of male connector 101 into positive engagement with the
receptacle pins of female connector 100. The locking lever 60 has a
shoulder portion 68 which serves to abut the outer surface of the
hook portion 64 of the catch bracket 66 and assist in separating
the male and female connector members 101 and 100 when
disconnecting them, as shown in FIG. 4b.
Having thus described the elements comprising a preferred
embodiment of a multi-point arrangement in accordance with the
present invention, it can be seen that the alignment mechanism
means 28 insures an exact alignment of the male pin elements of the
plug sections with the associated female receptacle sections 14, 16
of the female connector member when effecting coupling
therebetween. Additionally, the rearward camber provided on the
lower half length portions of the frame bars 10, 12, 18 and 20 of
the female and male connector members assures that the male plug
elements intermediate the length of the male connector member 101
will be properly and completely coupled to the associated female
receptacle sections intermediate the length of the female connector
member 100 during interengagement and coupling of the male and
female connector members as described.
While a preferred embodiment of the present invention has been
shown and described, it will be understood to those skilled in the
art that changes and modifications may be made therein without
departing from the invention in its broader aspects. For example a
single frame bar could be used on each connector, the vertical
median of the cross plate on the female connector being coincident
with the vertical median of the frame bar, the tongue on the male
connector having two forward portions, each engaging the cross
plate on either side of the single frame bar.
