ELECTRICAL ADAPTER
ABSTRACT OF THE DISCLOSURE
An adapter in accordance with the present invention comprises a male member joined to a female member.
The male member includes a plug portion having a plurality of spaced slots into which a plurality of blade contacts are respectively inserted, the blade contacts making elec-trical connection with conductors positioned within troughs that respectively communicate with the slots. Each conductor is doubled over within its associated trough, and both ends of each conductor are terminated with a wire spring contact. The contacts at one end of these conductors are mounted in a first contact carrier, while the contacts at the other end are mounted in a second contact carrier.
In addition, a plurality of conductors, also terminated at both ends with wire spring contacts, extend directly between the carriers.
The contact carriers are respectively accommodated within a pair of internally communicating openings in the female member in such a manner that the wire spring contacts are exposed within a pair of externally communicating opening of the female member. Each externally communicating opening is adapted to accommodate a plug having contacts arranged so as to engage the contacts of the associated carrier and thereby be electrically connected to the blade contacts in the plug portion and to the contacts of the other carrier.

Description

Field of the Invention This invention relates to the field of connectors and within that field to an adapter for providing multiple jac~ access at a single jack location.
B kground of the Invention The wall jack provided by telephone companies prov-des a single outlet for connecting telephone station equipment such as a telephone set to an associated telephone line. However, there are some situations where it is desirable to be able to connect two pieces of telephone station equipment to the telephone line in parallel at the same location. Thus for example, a telephone answering device is typically connected in parallel with an adjacent telephone set. There are other situations where it is desirable to be able to connect an external signal source or an auxiliary power supply to telephone station equipment at the same location andjor on the same premises, such as to provide power to an incandescent lamp mounted within a telephone set for illuminating the dial. There are still other situations where it is desirable to be able to rearrange the location of the contacts to which the tip and ring line conductors and/or power or other signal leads are connected.
There is therefore a need for an adapter to provide multiple jack access at a single jack location.
Summary of the Invention An adapter in accordance with the present invention has a T configuration with a plug portion forming the stem of the T and a pair of adjacent jack portions facing opposite to the plug portion forming the crossbar of the T. Each contact of the plug portion is electrically connected to a contact of each jack portion by a single conductor. The conductor is doubled over within a conductor receiving .... .. . _ _,. _ .
:108S011 trough in the plug portion wherein it is pierced by the associated plug contact.~
The ends of each conductor are joined to wire springs that are respectively mounted in each jack portion and serve as contacts of the jack portion. Thus the wire spring contacts of each conductor are connected in parallel to the associated plug contact in the plug portion. The conductive paths thereby provided can be used to connect two pieces of station equipment to the same wall jack. They can also be used to apply an auxiliary power source or external signal source to l)station equipment connected to the other jack portion of the adapter, and 2) via the premise wiring to station equipment at other location on the premises.
Other wire spring contact terminated conductors extend directly between selected positions of the two jack portions. The wire spring contacts terminating these conductors are therefore connected in series, and conductive paths that bypass the plug portion are provided that can be used to apply an external signal source or an external power source to only station equipment connected to the other jack portion.
The wire spring contacts mounted to the ends of each conductor may be mounted in each jack portion in positions that correspond to the position of the associated contact in the plug portion. However, the wire spring contacts may also be mounted in different positions relative to the associated plug contact so as to rearrange the locations at which power or signals may be obtained.
~ - 2 -In accordance with an aspect of the invention there is provided a multi-outlet adapter for plug-in telephones comprising: a male member including a plug portion having a plurality of troughs respectively communicating with a like plurality of slots in the plug portion; a plurality of conductors totally contained within the adapter, each conductor being doubled over within an individual trough in the plug portion and both ends of each conductor being terminated with a wire spring jack contact; a plurality of blade-like plug contacts respectively positioned within the slots in the plug portion, each plug contact making electrical connection with the conductor positioned in the associated trough whereby the jack contacts terminating the ends of the conductor are connected in parallel to the associated plug contact; a pair of contact carriers, each contact carrier having one of the jack contacts mounted therein; and a female member joined to the male member, the female member having a pair of jack openings open to the outside of the adapter, the female member also having means for accommodating an individual carrier adjacent to each of the jack openings such that the jack contacts mounted in the carriers are exposed within the jack openings.

FIG. 5 is an end view looking toward the jack portion of the adapter; and FIG. 6 is a top view with portions broken away showing one interconnection arrangement between the plug portion and the jack portions.
Detailed Description Referring to FIGS. 1 and 3 of the drawings, the adapter includes a male member lO joined to a female member 20. The male member 10 comprises a plug portion 12 that is integral with and extends from a housing portion 14. As seen most clearly in FIGS. 2 and 4, the plug portion 12 includes a plurality of spaced slots 15 into which a plurality of blade contacts 30 are respectively inserted, the blade contacts having tangs 32 that pierce through the insulation of and make electrical connection with conductors 40 positioned within troughs 16 that respectively communicate with the slots.
Referring now to FIGS. 4,5, and 6, each conductor 40 is doubled over within its associated trough 16, and both ends of each conductor are terminated with a wire spring contact 42.
--` 108501~
The contacts 42 at one end of the conductors 40 are mounted in a first contact carrier 50A, while the contacts at the other end of the conductors are mounted in a second contact carrier 50B. In addition, as shown in FIG. 6, two conductors 45, which are also terminated at both ends with wire spring contacts 42, extend directly between the contact carriers 50A and 50B.
The contact carriers 50A and 50B are identical as seen most clearly in FIG. 4. Each contact carrier 50A and 50B
is accommodated within the female member 20 in an internally communicating opening 22 whereby the contacts 42 are exposed within an externally communicating opening 24 in the female member. The internally communicating openings 22 and thereby the externally communicating openings 24 are side-by-side one another, and the externally communicating openings are adapted to accommodate plugs having contacts arranged so as to engage the contacts 42. The contacts of the plugs are thereby electrically connected to the blade contacts 30 in the plug portion 12 and to the contacts 42 of the other contact carrier 50.
Referring again to FIG. 1, the plug portion 12 includes a latch 18 that serves to secure the plug portion and thereby the adapter to a complementary jack. A
snap-in plunger 60 slidably mounted to the exterior of the housing portion 14 extends above the housing portion and is actuated to depress the latch 18 to release the plug portion from the associated jack.
Although a specific embodiment of the invention has been shown and described, it will be understood that it is but illustrative and that various modifications may be made herein without departing from the scope and spirit of this invention as defined in the appended claims.
