Description
Technical field
A kind of power connection is the utility model is related to, particularly a kind of power connection for individually drawing ground wire.
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, need, by ground wire independent grounding, so just to can guarantee that tester when the test of some equipment is carried out
Member safety, but the live wire of present power connection, ground wire and zero line be generally in same root wire, so just without
For method by ground wire independent grounding, 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 power connection for individually drawing ground wire.
Technical scheme is used by the invention for solving the technical problem：A kind of power connection for individually drawing ground wire, bag
Outer cover body is included, the front end of outer cover body is provided with rubber sleeve, and the rear end of outer cover body leads to the first wire and second and led
Line, the first wire are ground wires, the second wire be twisted after zero line wraps up insulating barrier with live wire together with, one end of rubber sleeve is set
There are neutral receptacle, line receptacle and ground receptacle, ground receptacle is arranged between neutral receptacle and line receptacle, and zero line is inserted
Mouth, line receptacle and ground receptacle pass through rubber sleeve, and one end is docked with power connection, and the other end docks with power supply, zero line
The inside of socket, line receptacle and ground receptacle is provided with anti-loose metal contact chip, the anti-loose metal contact chip
One end be provided with for fix wire overcoat first protrusion edge, first protrusion edge on the inside of be provided with for fixation lead
The second of line interior metal protrudes edge, is provided with the middle part of anti-loose metal contact chip for anti-loose metal contact chip to be consolidated
It is scheduled on the fixing hole and fixed groove of neutral receptacle, line receptacle or ground receptacle, neutral receptacle, line receptacle and ground wire
The inside of socket is provided with the fixed column being used cooperatively with fixing hole and fixed groove and fixed block.
Further, one end that rubber sleeve docks with power supply is provided with the fixation scrobicular ring for fixing rubber sleeve, described
Rubber sleeve and fixed scrobicular ring are integrally formed.The setting that the utility model fixes scrobicular ring is easy to that rubber sleeve is fixed, if
It is set to ring-type and has greatly reinforced fixed effect, is integrally formed the bulk strength for adding rubber sleeve.
Further, the fixed scrobicular ring includes front side edge and back side edge, and front side edge is higher than back side edge.The utility model is by before
Side is disposed above back side edge, so not only allows fixed scrobicular ring that rubber sleeve is fixed, and fixed
When can also to rubber sleeve carry out it is spacing.
Further, anti-loose metal contact chip is not provided with the one end at the first protrusion edge and is provided with multiple furcations, point
Flexible space is set between fork and furcation, and all furcations surround one ring of formation together.The utility model is so
Set when make it that power connection is attaching plug connection, metal contact chip can preferably fixed power source plug metal
Conduction column, improve the stable connection between attaching plug and power connection.
Further, the height at the first protrusion edge is higher than the height at the second protrusion edge, the width at the second protrusion edge
Width than the first protrusion edge is wide.The height at the first protrusion edge is higher than the height at the second protrusion edge, because wire
The external diameter of overcoat is more than the diameter of wire interior metal, therefore so sets fixed effect more preferable；The width at the second protrusion edge
Width than the first protrusion edge is wide, because wire interior metal is more smooth compared with wire overcoat, therefore increases by second
The width at protrusion edge advantageously ensures that the fixed effect to wire interior metal.
Further, the end of all furcations is stuck up outward forms angle with the not outer part stuck up, and the angle is more than three
Ten degree are less than 60 degree.The utility model, which is so set, causes power connection and attaching plug when docking, metal conduction
Post can be more easily inserted into metal contact chip, and the too small metal conduction column of angle is not easy to be directed at metal contact chip, and angle is too
The big elasticity reduction that can cause furcation again, is unfavorable for the fixation of metal conduction column, by multiple comparison test, finds angle
It is optimal that 30 degree, which are set greater than, less than 60 degree.
Further, the rear end of outer cover body is provided with retainer ring and stop collar, and the first wire and the second wire both pass through institute
Retainer ring is stated, retainer ring is linked together by stop collar and outer cover body.Retainer ring causes the profile more mark-on of outer cover body
Standardization, stop collar can limit the position of retainer ring so that the profile of outer cover body further standardizes.
Further, the upper and lower surface of outer cover body is provided with the forced section for being easy to power connection plug stress, it is described by
Power portion is made up of multiple semi-cylindrical projections.The forced section that the utility model is set is easy to user to pull out power connection
Insert, avoid fixing because of power connection and pull out to get off tightly very much.
The beneficial effects of the utility model are：The utility model be it is a kind of individually draw ground wire power connection, this practicality
The new ground wire using power connection is individually drawn as the first wire, is so easy to individually connect ground wire when test equipment
Ground, the safety of tester is effectively ensured;The the first protrusion edge and the second protrusion edge that the utility model is set can have
The fixed whole wire of effect, and metal contact chip can be clamped securely to zero by the fixing hole and fixed groove in metal contact chip
The inside of line jack, line receptacle or ground receptacle, releasing for metal contact chip is so not only effectively prevent, and effectively
Prevent releasing for wire；Wire overcoat and wire interior metal are individually fixed respectively, have not only greatly reinforced fixed effect
Fruit, and can prevent wire overcoat and wire interior metal from relative displacement occurs.
