Join, and the aforementioned one group of electrode as positive source conductive mechanism is inserted in the end of the first bus 74 of PTC heater 7
Aforesaid conductive electrode insertion chamber 522 between one piece of conductive reed 52 of the one of electrode mechanism in mechanism 5 and fixture block 53
Interior, and the end of the second bus 75 of PTC heater 7 is inserted the aforementioned one group of electrode machine as power cathode conductive mechanism
In aforesaid conductive electrode insertion chamber 522 between one piece of conductive reed 52 of another electrode mechanism in structure 5 and fixture block 53.Connect
And by tester, electric controller 3 is operated, so that conductive reed is oppressed and work with relieving mechanism 6, that is, so that push pedal is acted on
Cylinder 62（There is the cylinder of twin-tub post）Enter working condition, push pedal acting cylinder post 621 overhangs to cylinder body, drive push pedal 61 to one
The direction of group electrode mechanism 5 is i.e. to the right（With shown position state）Displacement, forces insulation contract block 64 displacement to the right by push pedal 61, makes
Insulation contract block 64 enters between the conductive reed 52 of two adjacent electrode mechanisms 5, forces the conductive reed with favorable elasticity
52 recline to the direction of briquetting 53, by the end folder of first, second bus 74,75 inserting positioned at conductive electrode in chamber 522
Live, that is, guarantee the compressing to first, second bus 74,75, be allowed to realize good electrical contact.In this condition,
Push pedal acting cylinder 62 break-off, and by tester, the corresponding button on electric controller 3 is operated, make warning mechanism 4
Connect with the power circuit of one group of electrode mechanism 5, PTC heater 7 is successfully attached in electric power loop.If PTC generates heat
The running voltage that device 7 is suitable for is 120V, then first make PTC heater 7 be in electricity the operation of electric controller 3 by tester
Press as, in the electric power loop of 120V, again voltage being risen to 240V after about 2 minutes and maintaining 2 minutes about；If PTC heater
7 running voltages being suitable for are 220V, then the proof voltage that first it is made with 220V is tested and maintained 2 minutes about, then by voltage liter
To 480V and maintain 2 minutes about, above-described holding time can be set by time controller, thus realizing
Automatic testing process.During aforementioned voltage-withstand test, if the situation that PTC heater 7 sparking, punctures etc, then
Electric power loop corresponding to the PTC heater 7 of this fault is cut off, and the warning lamp 43 of warning mechanism 4 extinguishes.So that sparking to occur it is
Example, the air switch on the circuit of corresponding conducting block connecting wire 5111 will disconnect, now corresponding PTC heater 7
Circuit is not turned on, and corresponding warning lamp 43 extinguishes, and tester just can easily determine and fail to lead to according to the extinguishing of warning lamp
Cross the PTC heater 7 of proof voltage test.By on-line testing personnel, the PTC heater 7 of fault is rejected after a loss of power, test knot
Shu Hou, aforesaid push pedal acting cylinder 62 reverse operation, and in the power-off state by the PTC heater 7 completing test take from,
Change the PTC heater 7 awaiting testing of next batch.
In sum, the technical scheme that the present invention provides overcomes the shortcoming in prior art, completes invention task, body
Show the technique effect referring in applicant's superincumbent technique effect hurdle, can yet be regarded as is that a ultimate attainment PTC that is controlled sends out
The technical scheme of hot device product quality.
