SUMMARY OF THE INVENTION
The invention provides new push-on friction fit connectors for ends of flexible ribbon LED light strips to form a continuous connection of the flexible ribbon light strips. The low voltage flexible light strips are cut at contacts periodically exposed along the strips. The ends of the strips with exposed contacts are pushed into openings in receivers. Wires in the receivers are bent inward in the openings and make friction electrical connections with the contacts at the ends of the strips. The wires extend through inward edges of the receivers and are soldered to exposed contacts on a printed circuit board on which the spaced receivers are mounted. Circuits within or printed on the circuit boards are connected to the spaced contacts on the printed circuit boards that are connected to the wires extending inward from the spaced receivers.
Tops and sides of the receivers and bottom edges of the circuit board are protected by two-part outer covers. The covers are bonded or sonically welded to the receivers and the circuit board, leaving only outer ends of the receivers and their openings exposed.
These and further and other objects and features of the invention are apparent in the disclosure, which include the above and ongoing written specification, with the drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
FIG. 1-25 show examples of push-in connectors for easily and smoothly connecting ends of LED lighting strips.
FIG. 1 shows an end-to-end connector 20 for a flexible LED lighting strip which is being inserted into one end of the connector. The end-to-end connector 20 has a square shape with openings 22 at opposite ends 24, 26. Each of the openings receives an end 12 of a flexible LED lighting strip 10. Exposed contacts 14 on the ends 12 are connected to flexible conductors embedded within the strip 10. LED lights 16 along the strip 10 are connected to the embedded conductors.
The connector 20 has positive (+) 32 and negative (−) 34 marks 30 on the connecting ends to ensure correct orientation of the connector 20 and correct insertion of ends 12 of strips 10 in openings 22. An arrow mark 36 on the connector 20 guides insertion directions of the strips and indicates the strip conducting power into and through the connector.
FIG. 2 shows a right angle 40 connector for connecting two flexible LED lighting strips 10. The right angle connector 40 has openings 42 in angularly related ends 44, 46 for inserting ends 12 with exposed contacts on adjacent perpendicularly oriented strips 10.
FIG. 3 shows a Y-connector 50 for connecting three flexible LED lighting strips 10. Connector 50 has openings 52 in three angularly related ends 54, 56, 58 for contacts 14 on receiving ends 12 of angularly related LED lighting strips 10. Markings 32, 34, 36 show polarities and orientation of connectors and lighting strip contact ends 12.
FIG. 4 shows an X or cross connector 60 for connecting four flexible LED lighting strips 10. Connector 60 has openings 62 in four angularly related ends 64, 66, 67, 68 for receiving ends 12 and contacts 14 of perpendicularly related LED lighting strips 10. Markings 32, 34, 36 show polarities and orientation of connectors and lighting strip contact ends 12.
FIG. 5 shows a T or perpendicular connector 70 for connecting three flexible LED lighting strips 10. Connector 70 has openings 72 in three angularly related ends 74, 76, 78 for receiving contacts 14 on ends 12 of angularly related LED lighting strips 10. Markings 32, 34, 36 show polarities and orientation of connectors and lighting strip contact ends 12.
As shown in FIGS. 6-25 each connector 20, 40, 50, 60, 70 has basic elements, a body 80 made of receivers 81, a printed circuit board base 83 with embedded printed circuits, mounting pads 82 on the printed circuit base, and a two-part cover 84 that covers and holds the elements, leaving exposed only openings 22, 42, 52, 62, 72 in the receivers 81.
As shown in FIGS. 6-10 in connector 20, the body 80 has two receivers 81 for securing on two mounting pads 82 mounted oppositely on a square circuit board base 83. As shown in FIG. 7 ends 91 of wires 90 extend from receivers 81 and are soldered to contacts 93 on the circuit board base 83. Inward bent loops or inward bent opposite ends of wires 90 within the receivers openings 22 frictionally engage exposed contacts 14 on ends 12 of the flexible lighting strips 10 when they are inserted in the openings 22 in receivers 81. Two-part covers 84 are bonded or sonically welded to the tops and outer sides of the receivers 81 and to the bottom of circuit board base 83, leaving only the ends and openings 22 of receivers 81 exposed, as shown in FIG. 8.
As shown in FIG. 9, the circuit board 83 used in connector 20 has two terminals J1 and J2 and embedded conductors 101, 102, 103, and 104, which respectively connect poles P1, P2, P3 and P4 in junctions J1 and J2.

A rounded circuit board base 83 has two mounting pads 82 and four exposed contacts 93 at each end of conductors that are buried in or exposed on the lower side of the circuit board base 83, as shown in FIG. 10. Two receivers 81 are mounted on pads 82, as shown in FIG. 11.
