DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fence for applying an electric shock to an animal that attempts to enter from outside or escapes from inside.

[0002]

2. Description of the Related Art In recent years, electric fences have been provided around fields and ranches in order to protect crops and livestock in the fields from wild animals or to prevent escape of livestock. Conventional electric fences are constructed by laying a plurality of bare electric wires around a field or the like at intervals above and below the ground, connecting the positive pole of a power supply that generates an impact voltage to the bare electric wire, Generally, the pole is grounded. In this case, when a wild animal or a livestock touches the bare electric wire, an impact current flows through the body and flows to the ground. For this reason, wild animals and the like receive an electric shock,
You will not get close to the electric fence.

[0003]

However, in the above-mentioned electric fence, since bare wires are provided near the ground, vegetation growing in a short time easily touches the bare wires and easily leaks electricity, and vegetation is frequently cut down. You need to do it. Also, depending on the state of the ground, even when a wild animal or the like touches the bare wire, an impact current may not flow through the body.

Further, in the case of an animal having an excellent intelligence such as a monkey, a tool or the like is used to pass through the electric fence so as not to touch the bare electric wire, so that the effect of preventing the invasion is sufficiently improved. The fact is that you cannot do it.

[0005]

SUMMARY OF THE INVENTION The present invention provides
In view of the above, the effect of preventing invasion of wild animals and escape of livestock is enhanced by combining a conductive fence body such as a wire net with a bare electric wire for applying an impact voltage. Hereinafter, the invention according to each claim will be specifically described.
