Not enough below this kind metering system exists:
1, testing clamp directly contacts with the instrument connection of pcb board, and operator's incorrect plank that very easily causes of exerting oneself is wiped flower, thereby increases scrappage, has increased production cost;
2, operation needs two people to carry out simultaneously, has increased cost of labor;
3, the instrument connection loose contact of testing clamp and plank reduces the accuracy of test data easily;
4, test speed is slow, and testing efficiency is low.
The utility model content
For this reason, the purpose of the utility model is to provide a kind of PCB power panel direct current resistance device for quick testing, to solve the problem that the existing test accuracy of present proving installation is not high, test speed is slow, efficient is low and cost is high.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of PCB power panel direct current resistance device for quick testing; Comprise at least one Estimate of Resistance for DC Low Resistance tester (1); Wherein also comprise a testing mould (2), this testing mould (2) is an insulation mold box (203), and said mold box (203) upper surface is provided with a plurality of testing needles (201); The side is provided with the copper rod (202) identical with above-mentioned testing needle (201) quantity, and connects one to one through spring between said testing needle (201) and the copper rod (202).
Wherein said Estimate of Resistance for DC Low Resistance tester (1) is provided with power switch (101), display screen (102), pilot lamp (103), range switch (104), test lead (105), range are set stop (106), power lead (107), p-wire (108) and testing clamp (109) as a result; Said testing clamp (109) one end corresponding clips are held on the copper rod (202), and the other end is connected with test lead (105) through p-wire (108).
The utility model is through increasing a testing mould; The Estimate of Resistance for DC Low Resistance tester is connected with copper rod on this testing mould; And be connected with testing needle on being arranged at testing mould through spring; Wiring board to be tested is placed on the testing mould, and wiring board instrument connection correspondence is contacted with testing needle, can realize test resistance.The utility model has avoided wiring board directly to contact with testing clamp; Avoided wiring board by the situation of scraping flower; Whole test process only needs a people to accomplish simultaneously; Reduced cost of labor, compared with prior art, the utlity model has that the wiring board test accuracy is high, test speed is fast, efficient is high and low cost and other advantages.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Identifier declaration among the figure: Estimate of Resistance for DC Low Resistance tester 1, power switch 101, display screen 102, pilot lamp 103, range switch 104, test lead 105, range are set stop 106, power lead 107, p-wire 108, testing clamp 109, testing mould 2, testing needle 201, copper rod 202, mold box 203 as a result.
Embodiment
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the utility model.The utility model provides a kind of PCB power panel direct current resistance device for quick testing, is used to solve the problem that the existing test accuracy of present wiring board direct current resistance proving installation is not high, test speed is slow, efficient is low and cost is high.
Wherein this device includes at least one Estimate of Resistance for DC Low Resistance tester 1; An and testing mould 2; Said testing mould 2 is an insulation mold box 203; Said mold box 203 upper surfaces are provided with a plurality of testing needles 201, and the side is provided with and the identical copper rod 202 of above-mentioned testing needle 201 quantity, and connects one to one through spring between said testing needle 201 and the copper rod 202.
Estimate of Resistance for DC Low Resistance tester 1 is provided with power switch 101, display screen 102, pilot lamp 103, range switch 104, test lead 105, range are set stop 106, power lead 107, p-wire 108 and testing clamp 109 as a result; Said testing clamp 109 1 end corresponding clips are held on the copper rod 202, and the other end is connected with test lead 105 through p-wire 108; Estimate of Resistance for DC Low Resistance tester 1 is connected with external power source through power lead 107.
Since on Estimate of Resistance for DC Low Resistance tester 1 only to two testing clamps 109 should be arranged; And should be directly proportional with the quantity of Estimate of Resistance for DC Low Resistance tester 1 corresponding to 202 quantity of the copper rod on the testing mould 2; Promptly an Estimate of Resistance for DC Low Resistance tester is corresponding to two copper rods; Therefore determined can simultaneously-measured direct current resistance quantity for copper rod 202 quantity on the testing mould 2, when a plurality of direct current resistance that needs to measure is arranged on the wiring board, in the time of can adopting many Estimate of Resistance for DC Low Resistance tester simultaneous it is measured.
