Description
BACKGROUND OF THE INVENTION
A widely used type of electrical connector assembly comprises a
pair of molded connector parts which are matable with each other
and which contain a plurality of electrical contact terminals so
that when the parts are mated, the terminals in the two parts will
be engaged with each other. Connectors of this general type are
frequently provided with a means to permit their being mounted in a
panel opening such as an opening of a fire wall of an automobile or
an internal panel of a domestic appliance, and with latching means
to latch the parts to each other when they are engaged and prevent
accidental disengagement. Some connectors of this general type are
provided with panel mounting means on only one part and the user
thus does not have a choice, when the connector assembly is
assembled to a piece of equipment, as to which part will be mounted
in the panel opening. However, many types of connectors have
integral mounting means on both of the connector parts so that a
connector of a given size and design can be used under a variety of
circumstances. An advantage of providing panel mounting means on
both parts is that a manufacturer of, say domestic applicances,
need not stock several specialized connectors for use under
different circumstances.
The instant invention is directed to the achievement of a connector
assembly having panel mounting means on both connector parts, so
that either part may be mounted in a panel opening, and having
latching means for holding the parts in their mated condition, the
latching means being arranged such that the parts can be disengaged
from each other regardless of which part is mounted in a panel
opening.
An object of the invention is therefore to provide a connector
assembly which can be used under a wide variety of circumstances. A
further object is to provide a connector assembly comprising a pair
of connector parts, which have mounting means for panel mounting
and which have latching means arranged such that either part can be
disengaged from the other by manipulation of the latching means
thereon.
These and other objects of the invention are achieved in a
preferred embodiment thereof comprising a pair of matable connector
parts or housings, each part having mounting means on two opposite
sides thereof permitting mounting of either part in a panel
opening. The remaining two sides of each connector part are
provided latch arms, one of the parts having latch arms which are
pivoted intermediate their ends and which have rearward ends which
can be pressed to move the forward ends of the latch arms away from
the surface of the connector part. The forward ends of this first
pair of latch arms are adapted to interengage with the barbed ends
of the second pair of latch arms on the other connector part. This
second pair of latch arms extends rearwardly toward the other
connector part and is integral with the connector part adjacent to
the rearward end thereof. The latch arms of the second pair can be
moved relatively towards the connector housing by merely applying
finger pressure to the arms intermediate their ends. The
arrangement is thus such that the interengaging means of the latch
arms can be disengaged by manipulation of either pair of latch arms
so that regardless of which connector part is mounted in a panel
opening, the other part can be removed from the mounted part.
In the drawings:
FIG. 1 is a perspective view of a connector assembly in accordance
with the invention showing the parts disengaged from each
other.
FIG. 2 is a side view of the receptacle part of the connector
assembly mounted in a panel opening.
FIG. 3 is a side view of the plug part of the assembly mounted in a
panel opening.
FIG. 4 is a top plan view of an assembly in accordance with the
invention showing the plug as mounted in the panel opening and
showing the receptacle disengaged from the plug.
FIG. 5 is a view similar to FIG. 4 but showing the parts engaged
with, and latched, to each other.
FIG. 6 is a view taken along the lines 6-6 of FIG. 5.
The disclosed form of connector assembly comprises a plug part 2,
and a receptacle part 4. The plug part 2 comprises block 6 of
molded insulating material having cavities 22 extending
therethrough from its rearward face 28 to its mating face 30.
Contact socket terminals 24 contained in the cavities 22 are
secured to wires 26 which extend rearwardly from the rearward face
of the block housing as shown.
The upper and lower sides, 8, 10, of the plug part, as viewed in
FIG. 1, are provided with integral mounting means 12 in the form of
trusslike structures comprising diagonally or obliquely extending
beams 14 and a transversely extending ridge piece 16. Two bema are
provided on the forward side of the ridge piece 16 and one beam on
the rearward side thereof, the beam on the rearward side being
offset with respect to the beams adjacent to the forward side so
that the entire structure can be flexed when the block is inserted
through an opening 20 in a panel 18. Further details of this
trusslike mounting structure are described in copending application
Ser. No. 786,954 filed of even date herewith.
The receptacle part 4 of the connector assembly is similar, in many
respects to the plug part 2 and corresponding structural features
of the receptacle part are therefore identified by the same
reference numerals (differentiated by prime marks) as those used in
the foregoing description of the plug part 2. The receptacle 4
differs from the plug 2 in that the former part is provided with an
integral hood 32 which extends forwardly beyond the mating face 30'
to protect the projecting ends of the contact pins 22' from damage,
the contact sockets mounted in the plug part being recessed within
their cavities so they are not subject to such damage.
The latching means on the plug part 2 comprises a pair of arms 34
which are connected intermediate their ends to the sides of the
housing by connecting sections 36 (FIG. 6). The arms themselves are
in the form of flat platelike elements extending from a location
adjacent to a rearward end of the housing to the mating end
thereof. The stiffness of the connecting sections 36 is such that
the forward ends 38 of these latch arms can be moved relatively
away from the housing by depressing the rearward ends of the arms.
The underside of the latch arms 34 have axially extending grooves
40 which extend to a location adjacent to the forward ends of the
arms to define inclined reentrant rearwardly facing shoulders
42.
The shoulders 42 and grooves 40 cooperate with the barbed ends 48
of the latch arms 44 on the receptacle part 4. These arms, 44, are
integral with the sides of the receptacle 4 adjacent to their
rearwards as shown in 46 and extend forwardly in spaced
relationship to the sides of the receptacle housing and the hood
32. It should be noted that the sides of the receptacle part 4 on
which the latch arms 44 are provided and recessed, as shown at 45,
in the area in which the latch arms are connected to the housing
and the sides of the hood 32 are slotted immediately beneath the
latch arms. This arrangement permits the latch arms to be located
very close to the sides of the receptacle 4 as shown in FIG. 4
while permitting sufficient inward movement of these latch arms
during engagement and disengagement of the parts. The barbed ends
48 of the arms define rearwardly facing shoulders 50 which have an
inclination corresponding to the inclination of the shoulders 42 of
the plug. The stiffness of the latch arms 44 is such that they can
be moved relatively inwardly toward the sides of the receptacle
housing by applying pressure to the sides of the arms intermediate
their ends.
In FIG. 4, the plug part of the assembly is shown as being mounted
in the opening in a panel 18 so that the rearward ends of the arms
34 extend through the panel opening and are thus inaccessible. The
receptacle part 4 can be mated to the plug part 2 upon rightward
movement of the receptacle from the position of the receptacle
shown in FIG. 4 to the position shown in FIG. 5. The inclined
leading ends of the arms 44 will move against the forward ends of
the arms 34 causing the arms 34 to pivot through a slight arc about
their intermediate supporting sections 36 until the barbed ends of
the arms 44 move into the slots 40 and the shoulders 42, 50 abut
each other. It is desired to disengage the connector parts from
each other, it is thus merely necessary to grasp the arms 44
between the thumb and forefinger and press these arms inwardly
towards the receptacle housing until the ends of the arms 44 move
out of engagement with the slots 40 and shoulders 42 of the arms
34. As noted previously, the sides of the hood 32 of the receptacle
are slotted immediately beneath the arms 44 so that these arms can
be moved inwardly a distance sufficient to effect such
disengagement.
When the connector assembly is used under circumstances such that
the receptacle, rather than the plug must be mounted in the opening
in the panel as shown in FIG. 2, the sides of the arms 44 will not
be accessible to effect disengagement but under these circumstances
the technician need only grasp the rearward ends of the arms 34
between the thumb and forefinger and press the rearward ends of
these arms inwardly thereby to move the forward ends of the arms
away from the sides of the plug housing and again effect
disengagement.
Changes in construction will occur to those skilled in the art and
various apparently different modifications and embodiments may be
made without departing from the scope of the invention. The matter
set forth in the foregoing description and accompanying drawings is
offered by way of illustration only.
