A connecting device, which can be connected to be a grounding device, includes an ontology equipped with a conductive plate and a conductor, which is electrically connected with the conductive plate. The conductor can be arranged with a conductive rod, a conductive clip or a conductive ring according to different electrical equipments. The conductive plate can be inserted in a waterline jack (or neutral line) of a stretched socket, and then the conductive rod is inserted in a grounding jack of the socket to make every jack of the socket connected to the ground at the same time. And also after the conductive plate is inserted in the waterline jack of the socket, the conductive clip is clipped to the grounding line of the electrical equipment or the conductive ring is locked to the grounding line of the electrical equipment to assure the electrical safety.

Description

The jockey that can be linked to be grounding function

Technical field

The utility model relates to a kind ofly can be linked to be ground connection simultaneously with each waterline jack of socket, the earth connection of electric equipment can also be connected on the waterline of socket and use the device of finishing ground connection.

Background technology

Electric current owing to can be subjected to the pollution of noise, surging etc., thereby may make that computer is undesired in transmission course, surging especially, and the electric current of this unexpected generation as the thunderbolt of moment, can burn fragile electronic chip; Surging produces when being the electrical equipment open and close machine of high capacity (power consumption is big) sometimes, also has plenty of because lightning hits the electric power transmission line to cause that howsoever, surging is the No.1 killer of high-accuracy electronic instrument.Whether power supply has earthing device also can have influence on effect, though because the noise surging of power supply can import underground dissipating through earth connection, if there is not earthing device, just it is narrow many then to get rid of the pipeline of noise surging again via the surge absorber filtering.

Based on Electrical Safety, general correct way should comprise three jacks with each group plug hole setting of electrical outlets or extended line socket, and one of them is a firewire jack, and one is waterline (or neutral line) jack, and another is an earth jack; Described firewire jack and waterline jack are to plant and the conducting electric current for the live wire conductive and the waterline conducting strip of three hair style plugs respectively, and earth jack is to plant for the contact rod of three hair style plugs, in order to leakage current is imported the earth.

Yet because present building laws does not have the standard of forcing to be provided with the safety ground system for electrical arrangement, so generally the supply socket of family is except the air conditioner private jack of 220V, all the other are two well format, the earth connection in the middle of having omitted.Therefore, general computer user when three hair style attaching plugs are inserted in two spring hole scokets, can earlier contact rod be fractureed need not, but just can not obtain grounding function thus.Based on this, when generally using a computer, user big city uses the extended line that possesses Three-hole socket (increasing by an earth jack) to plant for three attaching plugs of computer.For present general old-fashioned building mostly is the twoport type socket, itself there is no the installing of ground wire, so though use Three-hole socket to articulate, but still do not have grounding function.In addition, the double end plug that at present general electrical equipment all uses, it does not promptly have earthing device in essence, so as desire to be plugged in the socket in three holes, must use changeover plug conversion, but be connected to ground wire device as socket nothing itself, it still can't produce any ground connection usefulness on using.So generally speaking, unless building itself has promptly set in advance earthing device, otherwise the plug of any connection porous, itself all can't produce the effect of ground connection.

In addition, the electrical equipment that many power consumptions are bigger (as washing machine, microwave oven etc.) all can be provided with a safety ground wire terminal, in case the leak-stopping electricity takes place.But because the home environment of general family very do not improve and suitable grounding apparatus can't be provided, make the earth connection that is located at electric equipment pass into disuse mostly and earth-free, will improve the danger of use electric equipment thus.

Summary of the invention

The utility model is that mainly each the winding ground jack that solves three traditional hole extended line sockets does not also possess line grounding function simultaneously, inconvenience when consequently desiring to carry out ground connection.

The utility model is to solve the inconvenience that general electric equipment is bestowed ground connection in addition.

Last purpose of the present utility model, being to solve the jack that can't differentiate in advance on the socket is waterline jack or the puzzlement of the problem of firewire jack.

The utility model provides a kind of jockey that is linked to be grounding function, it is characterized in that being provided with a conducting strip at a body, and the conductor wire that is connected in this body and is connected with circuit with this conducting strip, this conductor wire is equipped with conductive component.The utility model is to be electrically connected mutually with a waterline conducting strip and a ground conductive bar, make this waterline conducting strip be inserted in the waterline jack of socket, this ground conductive bar then is inserted in the earth jack of Three-hole socket, and each waterline jack that just can make same socket is line and possess identical grounding function simultaneously.

The utility model also can utilize the clip that possesses conduction property to replace described contact rod, and described waterline conducting strip is inserted in the waterline jack of socket, and this conductive clip is held on the earth connection of electric equipment, just electric equipment can be connected ground connection with socket.

The utility model also can utilize the ring that possesses conduction property to replace described contact rod or conductive clip, described waterline conducting strip is inserted in the waterline jack of socket, and this conducting ring is locked in the earth connection of electric equipment, also electric equipment can be connected ground connection with socket.

The utility model is that waterline jack or firewire jack are avoided mispluging for the jack of differentiating on the socket, front end at conductor wire is coating an electrical verification sheet especially, and by an electric wire be connected indicator light and link to each other, when the conducting strip of the utility model body was inserted on the correct socket waterline jack, then can to light expression correct for indicator light; Otherwise if when being inserted in firewire jack, then indicator light just can not light.

Compare with prior art, the utility model is as long as be connected in the waterline jack and the earth jack of one group of Three-hole socket with winding ground jockey, just can allow each waterline jack line ground connection simultaneously on the same socket, and then reaches and use more convenient purpose.

Device provided by the utility model also can be easily be connected to socket and ground connection with the earth connection of electric equipment, and electric equipment generally is the place that is placed near socket, thereby more convenient on ground connection applies.

The utility model is because the electrical verification sheet that coating of conductor wire outside, thus the user can be easy to learn very soon by indicator light whether the utility model has the wrong plug jack, and do not need other auxiliary check Detecting device in addition.
