The socket is divided into an upper layer and a lower layer which are in double reed connection, and upper and lower layers of wiring terminals are connected with the double reeds through screws. The plug made of insulating material and taking a T shape is used transversely, wherein the front end is the head part of the plug and the rear end is the root of the plug, and the plug can be inserted into or pulled out of the socket.
Description
Technical field
A kind of electric current secondary loop of the utility model is measured verification and is used quick connector; Relate to the secondary table meter loop of power plant electric energy output metering, the electric energy output of electric substation of power supply administration or input metering, large enterprise's power distribution station electric energy input metering, belong to electrical instrument and other parts, corollary equipment technical field.
Background technology
Electric energy meter (kilowatt-hour meter) is State Grid Corporation of China and power plant, enterprise, and individual, the domestic consumer legal metering outfit that carries out the electric weight clearing.Because enterprise production and family life are to the supply requirement of electric energy and electric power; Especially special industry enterprise is to the uninterrupted requirement of supply of electrical energy; Make power-generating enterprise and State Grid Corporation of China, must twenty four hours uninterruptedly to electrical network, supply power to the enterprise customer.But electric energy meter (kilowatt-hour meter) must annual test as legal metering outfit, regularly, carry out verification and check.Traditional test verification way is with the qualified kilowatt-hour meter of verification in the sixth of the twelve Earthly Branches, displaces tested ammeter to the scene and takes back test institute, and after verification was waited to accomplish test by stages and in groups, secondary returned the scene, and former table meter is reinstalled the original place.Do two problems of existence like this, the one, it is not high from multiple efficiency to come and go the working site, and the 2nd, be the continuous operation that guarantees electrical production, the work of secondary circuit often all is live line working, can impact equipment and personal safety if any accident.In order to solve above-mentioned existing problems, further increase work efficiency, guarantee safety in production, existing way is to carry out the on-the-spot test verification.Carry out for guaranteeing the on-the-spot test verification everything goes well with your work; The utility model invention is a kind of; Electric current secondary loop is measured verification and is used quick connector, and the operation sequence when it has simplified staff's live line working provides guarantee from the technological improvement angle for the electrical production safe operation.It has played the saving of labor, has saved time, guaranteed the effect of safety in production.
Summary of the invention
The utility model invention is a kind of; Electric current secondary loop is measured verification and is used quick connector; Its goal of the invention is: in order to improve labor productivity, and with the fastest time, safest technical guarantee measure; Solve in the kilowatt-hour meter on-the-spot test verification contingent equipment and personal unsafe factor.
In order to realize the foregoing invention purpose, the utility model invention is a kind of, and electric current secondary loop is measured verification and used quick connector; It is made up of socket and plug two parts, and socket divides two-layer up and down, and the centre is designed with two-man act chip connected mode; The levels binding post is connected with the two-man act sheet through screw, and plug is that insulating material is processed the T word shape, laterally uses; Front end is the head of plug, and the rear end is the root of plug, can insert or extract in socket.
Further refinement analysis:
Said quick connector socket is connected through the two-man act sheet by terminal up and down, and the two-man act sheet of socket divides two up and down, is bent into former and later two contact-making surfaces respectively, sheet contact-making surface contact and connecting relatively up and down.Terminal and up and down between the two-man act sheet is fixedly connected with screw.This fixed screw is connected with external circuit through end word row.Reed is bent into former and later two contact-making surfaces up and down; Be in order to allow connector plug; When inserting socket bigger contact-making surface is arranged, can satisfy big electric current section needs first, second can make plug firm in socket, stable; Prevent single-point contact or contact-making surface is too small causes, plug rocks and causes short circuit and come off.Three moments in order to guarantee to insert at connector plug, contact instability in the time of can not producing because of insertion, and the triggering gap that forms outage phenomenon.When plug inserted last row's reed, tested loop was still in normal operation, and the master meter of this moment has sealed in circuit, but has just formed a diverter branch, and total loop is also in a loop.When plug continued to be inserted into back one row's reed, standard scale inserted tested loop fully.This classification is inserted, shunt the access way that afterwards seals in earlier, is the safe and effective procedure that the insertion current circuit is tested.
Said quick connector plug for insulating material is processed the T word shape, laterally uses.Front end is the head of plug, and the rear end is the root of plug, can insert or extract in socket.The header planes position of plug, branch upper strata are sheet metal, middle for insulating barrier, lower floor are the three-decker of sheet metal, and this structure appearance is to play interconnect function when inserting socket.The root of plug is little side's body, is provided with two jacks that are arranged above and below in square body front.In the jack respectively with plug up and down sheet metal be connected, this jack aims at external standard scale, seals in tested ammeter loop and designs.Can before sealing in standard scale, accomplish the wiring work of voltage circuit at leisure like this, shorten the on-line debugging time, farthest reduce because of debugging, and primary circuit is moved issuable influence.

Embodiment
In order further to understand the utility model, a kind of electric current secondary loop is measured the verification quick connector, and structure and connected mode now are explained as follows in conjunction with Figure of description.A kind of electric current secondary loop is measured verification and is used quick connector, and it is made up of socket 1, plug 2, two parts.
Socket 1 is made up of upper terminal 11, lower terminal 14, upper reed plate 12, following 13 of reeds.Between upper reed plate 12 and the upper terminal 11, be fixedly connected with screw through 17 screws.Between following reed 13 and the lower terminal 14, be fixedly connected with screw through 18 screws.The front-seat brace 15 of socket 1 last slice 12 with back row's brace 16 last slice 12 be consubstantiality bending formation.Following 13 of front-seat brace 15 and following 13 of back row's brace 16 are that the consubstantiality bending forms.Plug 2 is the T word shape, laterally uses.Flat position divides upper strata 21 to be sheet metal, and middle level 22 is an insulating barrier, and lower floor 23 is a sheet metal.Root is little side's body 24, the perforate that is arranged above and below of the front of little side's body 24, and last hole 25, hole 26 down are that standard scale connects socket.Last hole 25 is communicated with plug surface sheet metal 21; Following hole 26 is communicated with plug surface sheet metal 23; When plug 2 inserted the front-seat reed 15 of sockets 1, in 16 formation branch roads shuntings of brace 15 and brace, standard scale sealed in through jack 25,26 and tests the branch road shunting circuit.When plug 2 continued to be inserted into back row's reed 16, standard scale inserted tested loop fully, and brace 15 and 16 is linked as a conducting body through plug 2, and the branch road shunting disappears.Upper terminal 11 is connected with external circuit with lower terminal 14, and respectively with the fixed screw of terminal screw about in the of 17,18, row outwards connects through the end word.
