COMPLETE SPECIFICATION STANDARD PATENT Applicant(s): Address for Service: Invention Title: Burndy Corporation Richards Avenue Norwalk CONNECTICUT 06856 UNITED STATES OF AMERICA DAVIES COLLISON CAVE Patent Trade Mark Attorneys Level 10, 10 Barrack Street SYDNEY NSW 2000 Multipoint contact compression connector a full description of this invention, including the it known to me:- The following statement is best method of performing 5020 0718v/MS -1- BACKGROUND OF THE INVENTION This invention broadly pertains to electrical compression connectors for single strand or multistrand wire or cable conductors. More specifically, the present invention relates to three, and preferably four, conductors together in an electrical power distribution system.
Prior art compressible connectors are known in which more than three wires or cables are included in a single connector. For example, U.S. Patent 3,354,517 issued to Levinsky described a compressible connector having the provision for connecting four conductors together. This patent includes closure devices 15, 15' which would be difficult to use in a compression device.
U.S. Patent 3,322,888 issued to Zemels illustrates a compressible connector having four recesses extending the length of the connector. However, the two side recesses are not designed to receive conductors therein.
SUMMARY OF THE INVENTION In one form the invention is an electrical compression connector for connecting a plurality of electrical conductors or cables comprising: a connector body of compressible material adapted to be inserted into a crimping tool having two opposed curved die surfaces for the compression of the connector, said connector body provided with a central web portion, said central web portion provided with at least three recesses extending through the entire length of said connector body to allow for the inclusion of conductors within each of the recesses, the periphery of said connector body provided with at least four distinct, non-continuous points of contact with curved die surfaces of the crimping tool when said connector body is inserted within the crimping tool, prior to crimping; and wherein when force is applied to the crimping tool, 1 i 0718v/MS -2said connector body would compress, thereby compressing said connector body around the electrical conductors to be provided in said recesses and securing the electrical conductors therein.
BRIEF DESCRIPTION OF THE DRAWINGS The foregoinq and other objects and advantages of the present invention will be better understood with reference to the following detailed description of preferred embodiments thereof, which are illustrated, by way of example, in the accompanying drawings, wherein: FIG. 1 is a perspective view of a first embodiment of the present invention; FIG. 2 is a perspective view of a second embodiment of the present invention; FIG. 3 is a side elevational view of the second embodiment of the present invention provided in a crimping tool; FIG. 4 is a side elevationa' view of the first embodiment of the present invention provided in a crimping tool; FIG. 5 is a perspective drawing of the second embodiment of the present invention after the crinping process has been completed.
DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the present invention is shown with respect of FIGS. 1 and 4. These figures illustrate a compressible connector 10 having a main body 22 and two substantially parallel arms 14, 16 extending from this main body portion. The distal portion of arm 14 is curved inwardly at 15. However, it should be noted that both of the arms 14 and 16 could be provided without any curved portion. A first recess 18 is formed between the arms 14, 16 to allow placement of single strand or multistrand wire conductors or cables therein. A throat portion 21 extends downwardly from the main body 12 and flares out in several directions to form arm portions 20, 22 and 24. A second .d 1 'j.C 0718v/MS 3 recess 26 is formed between the body portions 12 and the arm A third recess 28 is formed between the body portion 12 and arm 22, and a fourth recess portion 30 is formed between arm 22 and arm 24. As a minimum, recesses 18 and 40 of Figures 1 and 2 must have appropriate conductors located within, while any one of recesses 26, 28, 30 of Figure 1 and 46, 47, 48 of Figure 2 must be filled. Variously sized wires or conductors can be provided within each of these recess portions.
When placed in a standard crimping tool having die surfaces 64 and 66, the connector 10 would come into contact with the interior surfaces of the dies at non-continuous points 68, 70, 72 and 74. As a compressive force is applied, these points will come into contact with the die surfaces, and the conductors provided in recesses 26, 28 and will receive direct compressive loads due to the unique geometric relationship between the connector and the die.
After the crimping process is terminated, conductors provided in these recesses would be secured in place.
FIGS. 2, 3 and 5 illustrate a second embodiment of the present invention. This embodiment depicts a compressible connector 32 provided with a main body portion 34 and two upwardly extending, substantially parallel leg portions 36, 38. A first recess 40 is provided between the leg portions 36, 38. A second recess 46 is provided in the central portion 34 below the leg 38, thereby forming a ridge 44.
Similarly, a third recess 48 is formed in the body portion 34 below the leg 36, thereby also creating a ridge portion 42. A curved leg 45 extends from the body portion 34 to a create a recess portion 47 below and between the recess portions 46 and 48. All of the recess portions 40, 46, 47 and 48 can receive various sized electrical conductors and cables therein.
When placed in a crimping device having die surfaces and 52, the connector 32 would contact the interior surfaces 0718v/MS -4of the die at non-continuous points 54, 56, 60 and 62. When compressive force is applied to this connection, it will initially contact at these points 54, 56, 58, 60 and 62.
The application of this force would then allow conductors 77, 76 and 78 to be secured and encircled by the body of the connector as illustrated in FIG. The connector of the present invention can be manufactured from tin-plated copper, aluminum or similar metallic materials which would appropriately deform when pressure is applied in standard mechanical, hydraulic and pneumatic crimping device.
While the present invention has been illustrated in connection with two preferred embodiments, it should be understood that many variations will occur to those skilled in the art, and that other types of compression connector geometries may but utilized.
