Abstract
The utility model belongs to the technical field of test devices and particularly relates to a device for improving the test efficiency of a bus board. The device comprises a power supply, a capacitor and a plurality of groups of on-off point test branches, wherein the capacitor is connected with the power supply in series; the on-off point test branches are connected with two ends of the power supply and the capacitor in parallel; each on-off point test branch consists of a resistor and a light-emitting diode which are connected in series; and contacts for corresponding to on-off points to be tested on a circuit board to be tested are respectively arranged at two ends of each test branch. The utility model overcomes the defects of long test time and low efficiency and accuracy due to dense test points of the bus board, effectively improves the test efficiency and avoids the repeated operation.
Description
Technical field
The utility model belongs to the proving installation technical field, is specifically related to a kind of device that improves the bus board testing efficiency.
Background technology
The servo-actuated bus board is made up of intensive break-make point, mainly by multimeter a plurality of break-make points on the bus board is carried out on off test in the test test process.When testing a circuit board in the conventional art, two hands of tester utilize multitester probe engaged test point number of times 128 times, totally 64 groups of break-make points.The easiest exposed problems is in this process: 1. because test point is many, and tester's maloperation in test process easily, thus cause reperformance test, take time and effort.2. because test point is many, it is disconnected that the frequent beep acoustic capacitance that multimeter produces causes that easily the tester judges by accident, thereby cause the test leakage phenomenon.3. if cause omission, false retrieval situation, the circuit board that then has omission, false retrieval result unexpected adverse consequences can occur in follow-up use.
Summary of the invention
The purpose of this utility model is at the prior art defective, provides a kind of testing efficiency very high bus board proving installation.
Realize the technical solution of the utility model: a kind of device that improves the bus board testing efficiency, it comprises power supply, electric capacity with power series, wherein, also comprise some groups of break-make point test branch roads that are connected in parallel on power supply and electric capacity two ends, the resistance and the light emitting diode of every break-make point test route serial connection are formed, every test branch road two ends all be provided be used for the circuit-under-test plate on the corresponding contact of tested break-make point.
Aforesaid a kind of device that improves the bus board testing efficiency, wherein, the described contact corresponding with tested break-make point on the circuit-under-test plate is connector.
Aforesaid a kind of device that improves the bus board testing efficiency, wherein, described test branch road has 128.
Aforesaid a kind of device that improves the bus board testing efficiency, wherein, described connector separates with proving installation, and both are electrically connected.
The beneficial effects of the utility model: the utility model has overcome because the intensive test duration that causes of bus board test point is long, and efficient is low, and the shortcoming that accuracy is low has improved testing efficiency effectively, has stopped repetitive operation.
Description of drawings
Fig. 1 is a kind of schematic diagram that improves the device of bus board testing efficiency described in the utility model;
Fig. 2 is the circuit layout card of Fig. 1.
Among the figure: 1. power supply, 2. electric capacity, 3. light emitting diode, 4. resistance, 5,6. connector, 7. left side test branch road group, 8. right test branch road group.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1: a kind of device that improves the bus board testing efficiency, it comprises power supply 1, the electric capacity 2 that is connected in series with power supply 1, some groups of break-make points that are connected in parallel on power supply 1 and electric capacity 2 two ends are tested branch roads, and the resistance 4 and the light emitting diode 3 of every break-make point test route serial connection are formed.Every test branch road two ends all be provided be used for the circuit-under-test plate on the corresponding contact of tested break-make point.
As shown in Figure 2, as a kind of embodiment of the present utility model, power supply 1 is arranged on the left side of whole device, and this power supply 1 is connected with outside, is used for supplying the electricity consumption of other electrical appliance of this device.Electric capacity 2 is split as two electric capacity, is separately positioned on the two ends of power supply 1.In this example, be set to two bigger connectors (5,6), be provided with and the corresponding contact pin of circuit-under-test plate jack at the lower surface of connector (5,6) with the contact that tested break-make point is corresponding on the circuit-under-test plate.In this example, because the restriction in space, the test branch road is split as two parts, is respectively left side test branch road group 7 and right test branch road group 8.Each test branch road group comprises some test branch roads, and each test branch road comprises the resistance 4 and the light emitting diode 3 of serial connection.
The foregoing description is at certain fixedly model circuit-under-test plate setting, if the break-make point that needs on the circuit-under-test plate to test surpasses 128, those skilled in the art can be according to the application's the technology contents number that the border situation increases or branch road is tested in minimizing factually.In addition, as a kind of form of distortion of the present utility model, also can be not at the lower surface of connector (5,6) contact pin be set, but can be electrically connected out special connector from connector (5,6), the special connector that picks out is used for being electrically connected with circuit-under-test.Space on the ifs circuit plate is enough big, also can the test branch road be split as left side test branch road group 7 and 8 two parts of right test branch road group, and the space on the ifs circuit plate is nervous more, also the test branch road can be split as more test branch road group.Above-mentioned distortion all be those skilled in the art according to teachings herein, can realize in conjunction with prior art.
