Abstract

Referring to Figure 3 a connector (10) for wires (11A, 11B) comprises a hollow body (12) having aligned openings (13A, 13B) for the passing therethrough of oppositely directed wire end portions (14A, 14B). Cams (15A, 15B) are rotatable on parallel axes (16A, 16B) between which lie the paths of the respective wire end portions (14A, 14B). Tension springs urge the cams (15A, 15B) respectively in the same rotational direction to urge inserted portions of the wires (11A, 11B) into frictional engagement with each other. The cams (16A, 16B) may be provided with ribs (20) to enhance their grip on the wires. The openings (13A, 13B) diverge outwardly to identify these openings and facilitate insertion of the wire ends. The two cams may be replaced by a double-ended cam with the wires inserted on either side. <IMAGE>

Description

CONNECTOR FOR WIRES ETC.
This invention relates to a connector for wires or the like, e.g., cables or strands, and more particularly - but not exclusively - for connecting together lengths of wire fencing, e.g., by connecting together corresponding line wires, or fencing wires, e.g., of any stock fence, or wires in vineyards.
An object of the invention is to provide a connector enabling wires to be connected together without being twisted, braided or welded.
Another object is to provide a connector not requiring use of any tools or at least any special or custom made tools.
Another object is to provide a connector affording a tensile strength greater than that of most fence wires.
Another object is to provide a connector enabling adjustment of tension in the wires being connected.
Another object is to provide a connector adapted for use with different and/or differing diameters of wires or the like.
Another object is to provide an electrically conductive connector particularly suitable for use in electric fences or with electric cables.
Another object is to provide a single durable connector capable of withstanding extremes of weather conditions.
According to the present invention, a connector for wires (or the like) comprises a hollow body having aligned openings in opposite sides for the passing therethrough of oppositely directed wire end portions, double cam means within the body rotatable between first cam positions in which wires can be inserted through the aligned openings and second cam positions in which the wire portions within the body are held against withdrawal from the body, and spring means urging the double cam means towards the second cam positions.
The wires (or the like) can be pushed into the connector and/or pulled from their ultimate ends to whatever extent is needed to ensure the requisite tension when the wires ease back to be held by the spring-loaded double cam means.
One size of connector may serve for two or more sizes of wire (or the like), depending on the size of the openings in the body sides and the range of throw of the double cam means, or two or more sizes of connector in accordance with the invention may be provided for individual wire sizes.
The double cam means may be a single camming member with diametrically opposed cam lobes situated between the paths of the respective wire end portions between the respective pairs of openings, with a single spring urging the camming member rotationally to urge the cam lobes towards respective abutments on the inside of the body, for gripping inserted wire portions between the respective cam lobes and abutments. The cam lobes may be ribbed, so as to enhance their grip on the wires.
Alternatively, the double cam means comprises two separate cams, which may be on a common axis with individual springs urging the cams in opposite rotational directions; or - preferably - the separate cams are on parallel axes between which lie the paths of the respective wire end portions in substantial alignment adjacent each other, with individual springs urging the cams in the same rotational direction to urge inserted wire portions into frictional engagement with each other. The cams may be ribbed, so as to enhance their grip on the wires.
The connector body may be made of plastics, but is preferably made of metal, e.g., a die cast body formed in two interengaging parts, with stainless steel cams and springs, affording a tensile strength greater than that of most fence wires, durability under extremes of weather conditions, and suitability for use in electric fences or with electric cables.
The entry openings for the wire ends preferably diverge outwardly to identify these openings and facilitate insertion of the wire ends.
Three embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a part section through a connector in accordance with the invention; Figure 2 corresponds to Figure 1 but shows wires held therein; Figure 3 corresponds to Figure 2 but shows ribbed cams; and Figure 4 corresponds to Figure 2 but shows a single camming member with ribbed cam lobes.
In the embodiment shown in Figures 1 and 2 a connector 10 for wires llA, 11B comprises a hollow body 12 having aligned openings 13A, 13B for the passing therethrough of oppositely directed wire end portions 14A, 14B. Cams 15A, 15B are rotatable on parallel axes 16A, 16B between which lie the paths 17A, 17B of the respective wire end portions 14A, 14B. Tension springs 18A, 18B urge the cams 15A, 15B respectively in the same rotational direction to urge inserted portions 19A, 19B of the wires 11A, 11B into frictional engagement with each other.
In the embodiment shown in Figure 3 the cams 16A, 16B are provided with ribs 20 to enhance their grip on the wires.
In the embodiment shown in Figure 4 a single camming member 21 is provided having diametrically opposed cam lobes 22A, 22B, with a single compression spring 23 urging the camming member 21 rotationally about its axis 24 to urge the lobes 22A, 22B towards respective abutments 25A, 25B on the inside of the body 12 thus gripping inserted wire portions 19A, 19B between the respective lobes 22A, 22B and abutments 25A, 25B. The cam lobes have ribs 20 to enhance their grip on the wires.
In each embodiment the connector body 12 is formed in two parts (only one shown) which are connected by means of pins 26, and in the first two-embodiments pins 26A, 26B also serve to anchor the springs 18A, 18B to the body, while in Figure 4 the spring 23 is compressed between a projection 27 extending within the body and one of the cam holes 22A. The openings 13A, 13B diverge outwardly to identify these openings and facilitate insertion of the wire ends.
