Claims. (Cl. 339--99) This invention relates to a circuit connector and particularly to a device for applying a plurality of lights on a Christmas tree.

In the art of applying decorative lights to Christmas trees or other devices where many lights are required, it is customary to bring a busline into the locality of the lights and to connect a plurality of cross circuits or branch circuits to the busline to provide the necessary plurality of outlets.

The present invention provides a connector for attaching a plurality of individual lights or branch lines to a bus as may be desired. The construction according to the present invention comprises a base having a plurality, preferably a pair, of longitudinally extending conductors in the base and transverse grooves in the base and each of the conductors having a prong or point extending into the groove so that they can be pressed into contact with an insulated wire extending through the groove. In practice, the points are so arranged that an insulating pair can be placed in the groove and the points will make contact with the opposite sides of the pair so that the branches may extend on opposite sides of the body and have lights connected thereto in any suitable way preferably by having a plurality of sockets connected in parallel across the branches.

It is accordingly an object of this invention to provide an improved circuit connector.

A still further object of this invention is to provide a connector having a large number of connections thereto.

It is a further object of this invention to provide a connector which can be utilized as an outlet or female plug for the connection of an extension cord.

Other objects and many of the attendant advantages will be apparent from the following detailed description taken in conjunction with the accompanying drawing, in which:

Figure l is an exploded perspective of the connector according to the invention;

Figure 2 is a longitudinal section through the connector showing the manner of connecting the points into the insulated conductors of the branch lines; and,

Figure 3 is a perspective view of a conductor element of the connection according to the invention.

In the exemplary embodiment according to the invention the connector includes a base constructed of a body of insulating material having

longitudinal slots

12 and 14 therein.

Conductor strips

16 and 18 are disposed in the

slots

12 and 14 and are preferably quite snugly fitted therein. The ends of the

strips

16 and 18 are angled as at 20 and 22 and the body 10 is provided with

angle slots

24 and 26 to receive the angled ends of the

strips

16 and 18. The strips may also be provided with anchor slots 28 to further anchor the slots in the body 10. The slots are also provided with transverse openings 30 adjacent the angled ends thereof for connection of the conductors of a bus. The body 10 is provided with a recess 32 which communicates with the ends of the

strips

16 and 18 and has an opening 34 therein so that the ends of a pair of conductors of the bus may extend into the recess and have the ends joined to the openings 30 in the

strips

16 and 18.

Apertures

36 and 38 are provided in the end of the body 10 and extend inwardly and communicate with the

conductor strips

16 and 18 so that the male plug of an extension cord may be extended into the

apertures

36 and 38 and make contact with the

strips

16 and 18 so that a plurality of the connectors may readily be con- 2,705,783 Patented Apr. 5, 1955 nected in series relation or an outlet or extension cord of any kind may be extended into the connector.

A plurality of transverse grooves 40 are provided in the body 10 and the

conductors

16 and 18 are provided with similar grooves 42. Grooves 42 being slightly larger than the grooves 40 so that the metal of the strips 16 and -18 is in nowise exposed in the transverse grooves 40.

Each of the

metal strips

16 and 18 is provided with points 44 which extend upwardly into the grooves 42 and are of sufiicient length that they extend upwardly an appreciable distance into the grooves 40 in the body 10. The points 44 of the strip 16 and the points 46 of the strip 18 are arranged so that they fall on opposite sides of the groove 48 so that a conductor pair 48 extending through the groove 40 will have one of the conductors such as 50 contacted by the point 46 while the other conductor 52 will be contacted by the point 44 so that the

conductors

50 and 52 will be connected respectively to the

conductors

18 and 16.

A cap or cover member 54 fits on the body 10 and the grooves 40 are of such dimensions that the cap 54 presses the twin conductors 48 down onto and into contact with the

points

44 and 46.

The cap or cover 54 will be attached to the body 10 by any suitable means such as the screw fasteners 56 which extend through apertures 58 of the cap and aperture 60 of the base 10. The screw members 56 may be either threaded into the aperture 60 or they may extend through the body 10 and be attached thereto by means of suitable nuts or other fasteners.

Matching apertures 62 may be placed at any desired part of the body 10 and the cap 54 preferably at a point remote from the

conductors

16 and 18 and from the grooves 40 so that cords or other fasteners may be extended therethrough for tying or otherwise mounting the connectors adjacent to the base such as a tree where the lights are to be used.

In the utilization of the connector according to the invention, a pair of conductors will be connected to the

strips

16 and 18 and if desired a plurality of such conductors may be connected together by inserting the male plugs of an extension into the

apertures

36 and 38. Any desired number of grooves 40 can be placed in the connectors and the conductor pairs 48 will extend therethrough and be pressed into intimate conducting relation therewith by means of the cap 54. The branch conductors extending in either direction from the connector may have any suitable devices applied therein such as decorating lights. Obviously, the decorating devices may be connected either in series or in parallel as may be desired. Should any of the branch conductors become injured or otherwise unsafe to use, they may be readily replaced with fresh conductors so that the system is maintained in safe condition for use under all conditions.

For purposes of exemplification a particular embodiment of the invention has been shown, and described according to the best present understanding thereof. Many changes and modifications can be made therein without departing from the true spirit of the invention.
