In addition, in the present embodiment, base is made up of upper and lower side insulating panel 5,6 and insulation column 7, insulation column is supported between the insulating panel of upper and lower side, make to form certain space between the insulating panel of upper and lower side, for the test lead of connecting test probe is placed between upper and lower insulating panel, make operating personnel not easily touch test lead, realize the object of safety test.
Certain base also can adopt the structure of one deck insulating panel, now test probe is plugged on base, comprise the part be positioned on the upside of insulating panel and the part be positioned on the downside of insulating panel, the part that wherein test probe is positioned on the downside of insulating panel links together with measure traverse line, metal conduction portions is made to be positioned on the downside of poly (methyl methacrylate) plate, the exposed outside of wire can be avoided like this, thus in test process, prevent tester's accidental shock accident from occurring, fully ensure the personal safety of tester.
Embodiment 3:
As shown in Figure 4, the present embodiment is substantially the same manner as Example 2, the part distinguished is: base adopts the structure of one deck insulating panel, now test probe is plugged on base, comprise the part be positioned on the upside of insulating panel and the part be positioned on the downside of insulating panel, the part that wherein test probe is positioned on the downside of insulating panel links together with measure traverse line, metal conduction portions is made to be positioned on the downside of poly (methyl methacrylate) plate, the exposed outside of wire can be avoided like this, thus in test process, prevent tester's accidental shock accident from occurring, also the personal safety of tester can be ensured.
In addition, on the upside of base, insulating panel is mounted with and unlocks baffle plate 9 and frame button 8 in the present embodiment, unblock baffle plate here and frame button are used for being fixed measurement plate.The installation site of frame button is in input test probe and the outside exporting test probe, here said outside is with input test probe and exports between test probe as inner side, all the other are outside, be divided into the outside of input test probe and export the outside of test probe, wherein a frame button is all at least installed in the outside of input test probe and the outside of output test probe, and unblock baffle plate is fixedly mounted on frame and buckles.Unlock baffle plate 9 to link with the deck 10 in frame button 8.
Unlock the poly (methyl methacrylate) plate material that baffle plate is strip, frame button is conciliate stopper plate and is used rivet to fix, and frame button uses screw to be directly fastened on the upper bed-plate of proving installation.
Embodiment 4:
Board test device measured by a kind of photovoltaic combiner box shunt of the present embodiment, comprise adjustable unblock baffle plate, frame button, position probe, test probe and base, its base is made up of upper and lower side insulating panel and insulation column, frame button, position probe and test probe are installed and are installed on the upside of security protection base on insulating panel, and the structure of installation site and template to be measured matches.
As shown in Figure 5, test probe in proving installation of the present invention is installed on the poly (methyl methacrylate) plate of security protection base upper end, its installation site and template connection terminal one_to_one corresponding to be measured, test probe one end directly and testing power supply line weld together, lower end and the measure traverse line of test probe link together, metal conduction portions is made to be embedded in security protection base, the exposed outside of wire can be avoided like this, thus in test process, prevent tester's accidental shock accident from occurring, fully ensure the personal safety of tester.
Adopt poly (methyl methacrylate) plate as the upside insulating panel of base in the present embodiment, as other embodiment, the upper and lower side panel that base also can adopt other insulating material to form.
As shown in figs 6-8, when reality is tested, the mounting hole measuring plate aims at position probe, is placed in position probe by measurement plate, and is fixed in frame and buckles.Owing to being subject to the restriction of position probe and frame button, measuring plate and can not loosen at upper and lower, left and right four direction, be conducive to the use when reality is tested.
During measurement, measurement plate four mounting holes are placed in position probe, pull unblock baffle plate, the deck that frame is buckled yearns for mobile opening, apply a vertical pressure then to measurement plate, the probe on base is accurately docked with terminal, unclamps unblock baffle plate simultaneously, the deck that frame is buckled restores, and completes the location and installation measuring plate.
The connection that this proving installation can allow tester realize all measuring plate terminal and test lead at synchronization be separated, because test probe one end is direct and testing power supply line welds together, the other end is directly connected with the welding pin measuring plate, measuring plate is plugged on the test probe of proving installation, use screwdriver to be carried out connecting or being separated with measurement plate by every root test lead one by one when testing without the need to tester, thus substantially increase testing efficiency.On the other hand, because test the end of a thread is connected on the probe of proving installation, and the probe of proving installation and measurement plate terminal one_to_one corresponding, if measure plate not according to the rules mode insert proving installation, the probe of proving installation then can occur with the terminal measuring plate that serious dislocation is that measurement plate and proving installation cannot correctly be located, thus fundamentally evades the possibility of wrong line.
In addition, the relatively common contact pin of the probe used in the present embodiment, inside has spring structure, it is flexible that needle portion can realize to a certain degree, in the present embodiment, needle portion has the flexible stroke of 5mm, as other embodiment, the stroke of syringe needle also can be adjusted according to practical situations.Adopt in this way, proving installation can be made to dock with measurement plate terminal flex, when measuring the flexible syringe needle by probe when plate terminal is not strictly welded on straight line, ensure that probe and the good contact measuring plate terminal, thus realize proving installation and the flexible docking measuring plate terminal.In other words, measure the accurate welding of plate terminal if can ensure, also can use the probe without flexible range.
After measurement plate arrives static stall, unclamp adjustable unblock baffle plate, measurement plate is fixed, power on and can complete test.
Be presented above concrete embodiment, but the present invention is not limited to described embodiment.Basic ideas of the present invention are above-mentioned basic scheme, and for those of ordinary skill in the art, according to instruction of the present invention, designing the model of various distortion, formula, parameter does not need to spend creative work.The change carried out embodiment without departing from the principles and spirit of the present invention, amendment, replacement and modification still fall within the scope of protection of the present invention.
