Embodiment
Please refer to Fig. 1-2; The present invention provides a kind of electric-conductor that is used for the aging test bench of electric tool or small household electrical appliance; Wherein aging test bench comprises: be positioned at the center and provide rotary power a rotating shaft 10, with rotating shaft 10 be the rotating disk 12 that is rotated of center be positioned at rotating disk 12 belows and with the electric-conductor 20 that links to each other with aging test bench power supply (not shown); Wherein this rotating disk 12 comprise several spaces and be circumferential arrangement station (120,121), be used for above-mentioned station (120,121) at interval dividing plate 122 be arranged on rotating disk 12 bottoms on and with the electric-conductor 20 electrical carbon brush groups 30 that contact; Wherein carbon brush group 30 is positioned at the top of electric-conductor 20, and the aging test bench power supply can switch through the 220V/110V transformation.
The station of aging test bench comprises that several aging stations 120 and 1 pick and place station 121, and in the present embodiment, aging station number is 13; Wherein each station all has the space of accommodating at least one product 40 to be measured; And it also comprises a socket 50, and these socket 50 1 ends and carbon brush group 30 are electrical connected, and the other end contacts with product 40 to be measured and is electrical connected; Picking and placeing station 121 is used to take or places product 40 to be measured; Represent the beginning or the end of burn-in test, the below that wherein picks and places station 121 is not provided with electric-conductor 20 yet, and is provided with carbon brush group 30 just now 12 times at the rotating disk that correspondence picks and places station 121 positions; And all there is electric-conductor 20 below of aging station 120, is used to carry out the burn-in test of product 40 to be measured.
Said electric-conductor 20 is circumferential arrangement; Adopt copper product; Its profile is an arc; It comprises at least and is connected with the aging test bench power ground and is first conductive part 22 of a continuous circular arc, is connected with the aging test bench power firestreak and comprises that several are second conductive part 24 of conductive unit 240 that the circle spacing is provided with each other, are connected with the aging test bench power firestreak and comprise that several are the 3rd conductive part 26 of the conductive unit 240 of circle spacing setting each other, and wherein carbon brush group 30 comprises first carbon brush 32, second carbon brush 34, the 3rd carbon brush 36 at least, and first carbon brush 32 remains with first conductive part 22 and contacts; And second carbon brush 34 and second conductive part, 24 Intermittent Contact; The 3rd carbon brush 36 and the 3rd conductive part 26 Intermittent Contact, wherein second conductive part 24 and the 3rd conductive part 26 be not on same circumference, in the present embodiment; Preferably; First conductive part 22 is positioned at the inboard, and the 3rd conductive part 26 is positioned at the outside, and 24 of second conductive parts are between first conductive part 22 and the 3rd conductive part 26.
Because second conductive part 24 adopts the conductive unit 240 that is provided with at interval and is positioned at aging station 120; Guarantee that each aging station 120 can independently draw electrical quantity; And the reason that increases by the 3rd conductive part 26 is because when second carbon brush 34 does not contact with second conductive part 24; The 3rd carbon brush 36 just contacts with the 3rd conductive part 26, is connected with aging test bench power supply (not shown) through electric-conductor 20 to guarantee carbon brush group 30 always.
During use; Along with the rotation of rotating shaft 10 drives rotating disk 12 rotations, product 40 to be measured enters into and picks and places the adjacent aging station 120 of station 121 from picking and placeing station 121, and carbon brush group 30 beginnings simultaneously electrically contact with electric-conductor 20 and begin to carry out a burn-in test; Aging station of rotating disk 12 every rotations; Product 40 to be measured just gets into a burn-in test, gets back to picking and placeing just end of circulation of experience on the station 121 again until rotating disk 12, and same carbon brush group 30 also rotates a circle along electric-conductor 20.The electrical quantity of each aging station 120 of while such as electric current etc.; All can show in real time; And judge the quality of product 40 to be measured and report to the police through the bound of setting electrical quantity; Product 40 to be measured in addition carries out the digestion time sum that equals each aging station 121 actual T.T. of burn-in test, and the digestion time of each aging station 121 then equals the stand-by period and adds rotational time.
Adopt the present invention, take up an area of for a short time, can design the station of varying number as required; To adapt to the different production beat; Can detect and show the electrical quantity of product to be measured at each aging station, different alarm range is set, can expose the latent defect of product to be measured simultaneously again rapidly.
When embodiments of the invention are illustrated and describe, conceivable is that those skilled in the art can design different correction examples of the present invention under the situation of spirit that does not break away from accompanying claims and scope.
