DESCRIPTION:
BRIEF SUMMARY
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.
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 compact connector enabling wires to be connected together in close alignment.
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 particularly suitable for use with high tensile wires.
Another object is to provide a re-usable connector for wires or the like.
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 body having through passage means adapted to receive a pair of oppositely directed wire end portions in close lengthwise relationship with each other, channels within the body one to each side of the through passage means acutely inclined to and, at their inner ends, breaking into the through passage means, and wedge means within the channels adapted upon attempted withdrawal of either of the wire end portions from the through passage means to urge the wires therebetween forcibly towards each other, whereby friction secures them firmly in the connector.
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 or the like ease back to be gripped by the wedge means.
One size of connector may serve for two or more sizes of wire, depending on the size of the through passage means and the range of convergence of the wedge means, or two or more sizes of connector in accordance with the invention may be provided for individual wire sizes.
The wedge means preferably comprises a pair of balls (or rollers) guided within the channels, together with springs urging the balls (or rollers) towards the through passage means.
The channel s m ay be provided within a plastics moulding, and the springs may consist of integral bows of plastics having their free ends pushing the balls (or rollers) towards the through passage means. The body could be a one-piece plastics moulding with the through passage means and channels for the balls (or rollers) included therein, and the balls (or rollers) could also be form ed of plastics. Alternatively, the body could be a seamless metal sleeve, e.g. of stainless steel or other non-corrosive metal, of flattened round section, with a moulded plastics insert having the through passage means inclined across the flattened section of the sleeve, the guide channels one from each end and opposite sides of the through passage means, and the integral spring bows; and the balls (or rollers) also formed of stainless steel (or other non-corrosive metal); w hereby when the connector is in use the wire end portions will be "sandwiched" by the stainless steel balls (or rollers) within the stainless steel sleeve. The spring bows may have projecting manual grip means (e.g., lateral tabs on the spring bows) to assist release of the balls (or rollers) to enable the wires to be disconnected, e.g., when dismantling or repairing a fence, and the connector may be re-used.
Again, the body may be formed from solid metal, with a through bore or twin bores
