The invention relates to a wire tensioner for use in electric wire fences. The device comprises tension means for holding electric fencing wire, the tension means being located within an insulated body or housing <B>8</B>. The device may attach a wire into a hole or socket in a fence post. The device comprises an insulating means or body <B>8</B> which has an engagement face for engaging with internal surface of a fence post and a compression spring <B>4</B> for applying a tensioning force to the wire. Any changes in the length of the wire due to ambient temperature variation can be absorbed by the spring <B>4</B>, thus minimising maintenance adjustments of the wire tension. The spring <B>4</B> may also press the engagement face against the surface of the fence post, and therefore hold the device in position. The present invention also provides for installing the wire tensioner devices inside a fence post which is fitted with a cover and which contains high voltage (HV) and earth wire connections. |
