Abstract
A connector for wires 11A, 11B Figure 3, comprises spring steel strip 12 bent into the form of a Z (or N) housed in a hollow body 13 with the diagonal 14 constrained against rotation in the mid-plane of the Z (or N). The diagonal has a central aperture 15 allowing passage of oppositely directed wire end portions 16A, 16B passing through the body. The arms 19A, 19B of the spring are so biased that attempted withdraw of either wire end portion is prevented by gripping action between the end of the respective arm and that end portion. Notches are provided in the ends of the arms for positive location with respective wire ends and to enhance the gripping action by increased edge and wire engagement. Alternatively, Fig. 6, the wire ends are gripped by the ends of spring-biased members. The connector may be used with electric fence wire or electric cables. <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 one aspect of the present invention, a
connector for wires (or the like) comprises a length of spring steel strip bent into the form of a Z (or N) with aligned holes in the diagonal and the arms (or limbs) to receive a pair of oppositely directed wire end portions, the size and/or shape of the holes, and/or spring biassing of the arms (or limbs) being such that attempted withdrawal of either wire end portion is prevented by gripping action between the respective hole in the respective arm (or limb) and that wire end portion.
The wires (or the like) can be pushed through 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 holes in the spring-biassed arms (or limbs).
The direction of spring-biassing of the arms (or limbs) is preferably such that tension in the wire end portions will cause them to move closer together, even to the extent of making contact in a single hole in the diagonal of the Z (or N), thus enabling the wires to be connected together in close alignment.
The connector may be housed in a plastics or, preferably, metal, e.g., die-cast, interengaging two-part housing provided in one or both parts with location surfaces for the connector and entry and exit holes for wire ends (in register with those in the connector). The entry holes prefer.ab.ly diverge outwardly to: identify these holes and facilitate insertion of wire ends.
According to another aspect of the present invention, a connector for wires (or the like) comprises a length of spring steel strip having a central aperture, and a spring steel element held captive within the aperture, with two openings formed between the end portions of the element and the ends of the aperture to receive a pair of oppositely directed wire end portions, insertion of the wire end portions being effective to bias the spring steel element so that attempted withdrawal of either wire end portion is prevented by gripping action between the respective edges of the respective opening.
This connector too may be housed in a plastics or metal housing similar to that described above.
According to a further aspect of the invention, a connector for wires (or the like) comprises a length of spring steel strip bent into the form of a Z (or N) housed in a hollow body with the diagonal of the Z (or N) constrained against rotation in the mid-plane of the Z (or N), the diagonal having a central aperture allowing passage of oppositely directed wire end portions passing between respective entry and exit holes in opposite sides of the body, and the arms (or limbs) of the Z (or N) being biased so that attempted withdrawal of either wire end portion is prevented by gripping action between the end of the respective arm (or limb) and that wire end portion.
The ends of the arms (or limbs) are preferably provided with semicircular or V-shaped notches for positive location with respective wire ends and enhancing the gripping action by increased edge and wire engagement.
The body may be of similar material and construction to the housings described above.
According to yet another aspect of 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, and a pair of spring devices located in pockets in the body and biassed so that attempted withdrawal of either wire end portion is prevented by gripping action between the respective spring device and an abutment facing the respective pocket.
This body too may be of similar material and construction to the housings described above.
Each spring device may be formed by a bent spring steel strip one limb of which bears against a side of the respective pocket to urge the free end of the other limb towards the respective abutment. Alternatively, each spring device may comprise a compression spring between a side of the respective pocket and a lever arm having one end pivoted in a back corner of the pocket and the other end urged towards the respective abutment. The wire engaging ends of the limbs or arms are preferably provided with semicircular or V-shaped notches for positive location with respective wire ends and enhancing the gripping action by increased edge and wire engagement.
Two embodiments of the invention will now be descr;i;bed.~, by. .way of example only, with reference to the accompanyjag: drawings, in which: Figure 1 is a cross-section through a connector in accordance.' with the second aspect of the invention;.
Figure 2 is a section on the lines II-II of Figure 1;
Figure 3 corresponds to Figure 1 but shows wires held in the connector;
Figure 4 is a section on the line IV-IV of Figure 3;
Figure 5 is a cross-section through a connector in accordance with the third aspect of the invention; and
Figure 6 corresponds to Figure 5 but shows wires held in the connector.
In the embodiment shown in Figures 1 to 4 a connector 10 for wires llA, llB comprises a length of spring steel strip 12 bent into the form of a Z (or N) housed in a hollow body 13 with the diagonal 14 of the Z (or N) constrained against rotation in the mid-plane of the Z (or N), the diagonal 14 has a central aperture 15 allowing passage of oppositely directed wire end portions 16A, 16B passing between respective entry and exit holes 17A, 17B and 18A, 18B in opposite sides of the body 13, and the arms (or limbs) 19A, 19B of the Z (or N) being biased so that attempted withdrawal of either wire end portion 16A, 16B is prevented by gripping action between the end of the respective arm (or limb) 19A, 19B and that end portion.
In the embodiment shown in Figures 5 and 6 a connector 20 for wires 21A, 21B comprises a hollow body 22 having aligned openings 23X, 23Y for the passage therethrough of oppositely directed wire end portions 24A, 24B and a pair of spring devices located in pockets 25A, 25B in the body, each spring device comprising a compression spring 26A, 26B between a side 27A, 27B of a respective pocket 25A, 25B and a lever arm 28A, 28B having one end pivoted in aback corner of the pocket and the other end urged towards the respective abutment.
In both embodiments notches 30 are provided in the ends of the arms 19A, 19B and the wire engaging ends of the lever arms 28A, 29 for positive location with respective wire ends and to enhance the gripping action by increased edge and wire engagement.
