Claims
What is claimed is:
1. In an illuminated electrical receptacle device, the combination
including a nonconductive body means having electrical receptor
means, a nonconductive cover means having apertures corresponding
to said receptor means and through which connector blade means can
be removably inserted, said cover means having an open area for
receiving lens means, grounding strap means insertable between said
body means and cover means, said grounding strap means having
apertures corresponding to the apertures in said cover means and
said open area, illuminating means locatable under said cover
means, and lens means insertable in said open area of said cover
means, said lens means having gripping means for engaging said
cover means and grounding strap means for removably holding said
cover means, grounding strap and lens means in assembled
relation.
2. In a receptacle device as claimed in claim 1 wherein the strap
means has a underside and the gripping means of said lens means has
resilient depending legs which can enter said open area and engage
the underside of said strap means for holding the cover means and
grounding strap means in assembled relation.
3. In a receptacle device as claimed in claim 2 wherein said legs
have inturned lips.
4. In a receptacle device as claimed in claim 1 wherein said cover
means has grounding plug apertures in addition to the apertures
corresponding to said receptor means in the cover and safety
shutter means normally covering said apertures but being openable
by a connector with a grounding plug.
5. In a receptacle device as claimed in claim 1 and including
removable nonconductive means in the aperture in said grounding
strap means adjacent to said illuminating means.
Description
This invention relates to electrical receptacles with an
illuminated cover therein.
Illuminated electrical receptacles are known in the art such as
found in U.S. Pat. Nos. 3,056,897; 3,061,716; 3,307,030 and
3,588,489. It is desirable in mass production of the receptacles
involved to be able to assemble the various parts thereof in an
efficacious manner. Also, it is desirable to be able to disassemble
the parts when replacements may be needed such as of the
illuminating means.
One of the objects of the invention is to provide a receptacle
construction which will facilitate assembly.
In one aspect of the invention, a receptacle for receiving
electrical connection devices has a nonconductive body and cover
with a grounding strap therebetween. The cover is provided with an
aperture or opening for receiving a lens which can be illuminated
by light or illuminating means within the assembled structure. The
lens has a gripping means for holding the lens in the cover and
also holding the grounding strap in assembled relation. The lens
accomplishes the gripping action by depending lugs which are
flexible so as to snap over the edges of the strap.
Other objects, advantages and features of the invention will become
apparent from the accompanying description and drawings, which are
merely exemplary.
In the drawings:
FIG. 1 is a top view of an assembled receptacle;
FIG. 2 is a bottom view of the cover with the strap indicated in
dotted lines and the lens indicated in dotted lines and the lens in
place;
FIG. 3 is a cross-sectional view taken in the direction 3--3 of
FIG. 2 with the outside of the lens facing upwardly;
FIG. 4 is a view looking in the direction 4--4 of FIG. 3;
FIG. 5 is a fragmentary sectional view looking along the line 6--6
of FIG. 3;
FIG. 6 is a fragmentary view of a portion of FIG. 2 showing the
receptacle with a grounding plug or blade therein; and
FIG. 7 is an exploded view of the various parts before
assembly.
The invention will be described in conjunction with a safety slide
receptacle, but the lens and assembly means can be used without the
safety slide.
Nonconductive body 10 can have conventional various plug blade
receiving contact elements (not shown) for receiving receptacle
blades in a known manner for one or more receptacles. Terminals 11
are provided for making connections from the service wires to the
various blade receiving contact elements. In the form shown, metal
or conductive grounding strap 12 is provided with a terminal 13 for
a connection to ground as it is known in the art.
Nonconductive cover 14 has blade receiving apertures 15 therein
which can have depending walls 16 extending through mating
apertures in the grounding strap 12 so as to insulate contact
blades extending therethrough from the strap.
The cover 14 has an open area 17 for receiving lens 18. The
grounding strap 12 has an aperture 19 therethrough to permit light
from an electric lamp or illuminating means 20 to illuminate the
lens. The lamp is connected across buses 21 and 22 so as to be
energized by the source of power. Terminals 11 are connected to the
bus straps 21 and 22. The lamp can be of any suitable type.
Lens 18 may be of a suitable plastic having the necessary
resilience and also light transmitting quality as needed. It can be
made of various color plastics and can have imprinted thereon any
desired legend.
Lens 18 is generally rectangular and has depending legs 23, 24 with
inturned lips 25, 26 for engaging the bottom of strap 12. Lens 18
also has overhanging strips or ledges 27, 28 (FIG. 3) for
contacting the top surface of the cover plate when in assembled
relation.
The grounding strap 12 has cutaway portions 29, 30 (FIG. 7) through
which legs 23, 24 can pass.
In assemblng the structure, cover plate 14 has grounding strap 12
placed thereon as seen in FIG. 3 with the apertures properly
aligned in respect thereto. The lens 18 then is inserted from the
top and pressed downwardly. Legs 24 will pass through cuts 29, 30
and spring outwardly so that the ledges or legs 25, 26 will pass
downwardly and snap into place under the grounding strap 12 and
hold the cover and grounding plate in assembled relation. Similarly
if desired, the lens can be snapped out of assembled relation.
The assembled cover, lens and ground plate then can be assembled to
body 10 in the usual manner such as can be seen from the exploded
view of FIG. 7.
An insulating strip or bushing 38 having grooves can be resiliently
inserted at the edge of the opening 31 (FIG. 7) in the grounding
strap 12 so as to protect wires 32 from the metal strap.
In the embodiment shown, grounding plug apertures 33 in the strap
12 may have contact means 34 depending therefrom to receive the
grounding plug of a fitting to be connected.
In the form shown, safety shields or shutters 35 (FIGS. 2, 6) may
be urged by springs 36 to the right (FIG. 2) so that end 37 thereof
will cover one of the adjacent apertures 15 so as to prevent use of
a connector without a grounding plug.
When a connector with a grounding plug is inserted into the
receptacle, the grounding plug will enter grounding plug hole 33
and cam the safety shield to the left, as seen in FIG. 6, so as to
open the contiguous aperture 15, springs 36 being compressed by
such an action.
The safety shutters and springs can be assembled in the cam slots
in the cover, the grounding strap placed thereon and then the lens
snapped into place.
The lens assembly arrangement can be used with or without the
grounding plug arrangement.
It should be apparent that details of construction can be varied
without departing from the spirit of the invention except as
defined in the appended claims.
