Description
Technical field
A kind of power connection is the utility model is related to, particularly a kind of equipment detection power source special joint.
Background technology
Electricity is a kind of people's now essential energy in daily life, usually needs to connect in electric wire when electricity consumption
To connect, electric power connecting head is at this time just needed to use, connect the metal conduction column insertion power supply of attaching plug when use
The metal contact chip of head.But current power connection generally existing problems with：1. by plant-grid connection power connection when
Waiting needs the insulating barrier peeling of wire appearance, but so exposes the metallic conductor come very easily short circuit, causes safety
Hidden danger, threaten the security of the lives and property of people；2. in use for some time, the metal contact chip inside power connection is because frequency
The plug of numerous ground easily loosens, and so can not only shorten the service life of power connection, and easily causes potential safety hazard, and threat makes
The security of the lives and property of user；3. need, by ground wire independent grounding, so just to can guarantee that when the test of some equipment is carried out
The safety of tester, but the live wire of present power connection, ground wire and zero line be generally in same root wire, this
Sample just can not be by ground wire independent grounding, and the personal safety to tester causes hidden danger.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide a kind of equipment detection power source special joint.
Technical scheme is used by the invention for solving the technical problem：A kind of equipment detects power source special joint, including
Outer cover body, the front end of outer cover body are provided with rubber sleeve, and the rear end of outer cover body leads to the first wire and the second wire,
First wire is ground wire, the second wire be twisted after zero line wraps up insulating barrier with live wire together with, rubber sleeve is provided with zero line and inserted
Mouth, line receptacle and ground receptacle, ground receptacle are arranged between neutral receptacle and line receptacle, and neutral receptacle, live wire are inserted
Mouth and ground receptacle pass through rubber sleeve, and one end is docked with power connection, and the other end docks with power supply, rubber sleeve and power supply
