The elastic sheet bodies are provided with shear marks corresponding to the slotted holes, the connecting pins of the transformer coil are extended in the mercury in the slotted holes via passing through the shear marks, and the mercury having high density is not easy to mix with impurities and is used for connecting the connecting pins of the transformer coil with the signal conducting wires. The utility model has the advantages of favorable contact performance and the capability of adapting to the test of various transformers.

Description

The plug assembly that the transformer characteristic tester uses

The utility model relates to a kind of plug assembly, relates to a kind of plug assembly that uses, the transformer coil pin is connected with the transformer testing instrument Communication signal wire for the transformer characteristic tester or rather.

At present, transformer plug assembly for the use of transformer characteristic tester, comprise a slide, on the left and right end face of slide, be respectively equipped with ccontaining shell fragment slotted eye, shell fragment slotted eye top is provided with the space of ccontaining slide block, be connected with slide for slide block, on the end face of the left and right sides of slide block, be respectively equipped with several shell fragment slotted eyes, make shell fragment be able to once embed in the shell fragment slotted eye by slide and slide block.The bottom of shell fragment is welded with signal line, and signal line is connected with transformer testing instrument.During use transformer to be measured is placed on the slide block, allows the transformer coil pin embed in the shell fragment slotted eye and contact with shell fragment, the operator can observe test case by the display on the tester.

Because this plug assembly is made electrically-conducting medi with shell fragment, make the transformer coil pin contact conducting with the lead of tester, but when shell fragment follow the string or shell fragment on when foreign material are arranged, transformer coil pin and shell fragment loose contact conduction are not good, will cause the inaccurate even mistake of test result.

The purpose of this utility model is that a kind of transformer characteristic of design is surveyed the plug assembly that the formula instrument uses, to being that the plug assembly structure of conductive media makes improvements design with the shell fragment, the mercury that conductivity is arranged with the density height is as conductive medium matter, pegs graft and remains good electrically contacting property applicable to the transformer coil pin of each sharp specification.

The plug assembly that the utility model transformer characteristic tester uses comprises pedestal and the spliced eye that is opened on the pedestal, has Communication signal wire to be connected to the transformer characteristic tester in the spliced eye, it is characterized in that:

Described spliced eye is arranged on the slotted eye on the pedestal, and described Communication signal wire connects and is located at the position corresponding with slotted eye, pedestal bottom and stretches in the slotted eye, also includes the mercury that is arranged in the slotted eye, and the transformer coil pin is plugged on that slotted eye is interior to be contacted with mercury.

Also include on the slotted eye face that the Thin Elastic lamellar body cements in the pedestal end face, it is corresponding with slotted eye to offer cut channel on the Thin Elastic lamellar body, and described transformer coil pin passes in the mercury that cut channel stretches into slotted eye.

Highdensity mercury has conductivity, and is difficult for mixing with impurity, and the transformer coil pin is plugged in the slotted eye mercury, makes the good electrical connection of pin and Communication signal wire maintenance, in addition, flexible thin slice body stop that mercury can not spill in the slotted eye.

Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing

Fig. 1 is the plug assembly perspective view;

Fig. 2 is a 2-2 line cross-sectional view among Fig. 1;

Fig. 3 is a plug assembly user mode schematic diagram;

Referring to Fig. 1, Fig. 2, the plug assembly 10 that the transformer characteristic tester uses is provided with pedestal 1, on pedestal 1, establish several slotted eyes that does not run through 11, be equipped with signal line 3 in pedestal 1 bottom and each slotted eye 11 corresponding positions, signal line 3 other ends are connected with transformer testing instrument 4, are provided with mercury 5 (see figure 2)s that the density height has conductivity in the slotted eye 11.The sticking Thin Elastic lamellar body 6 that is provided with on the pedestal 1, on thin slice body 6, be provided with the cut channel 61 that forms by the cutting knife cutting with slotted eye 11 corresponding positions, mercury 5 in the slotted eye 11 can not spill because of stopped by the thin slice body, also can on pedestal 1 cover plate be set, and mercury overflows in the slotted eye further to avoid.

Referring to Fig. 3, during the test transformer characteristic, transformer 7 is placed on the Thin Elastic lamellar body 6 of pedestal, transformer coil pin 71 is passed in the cut channel 61 and insertion slotted eye 11 of thin slice body 6.When transformer coil pin 71 is inserted by cut channel 61 places of thin slice body 6, the cut channel 61 both sides ora terminalis that pin 71 can make thin slice body 6 are toward down interior and make the opening of cut channel 61 become big, and the elasticity of thin slice body 6 can make the opening of cut channel 61 recover the driving fit shape when transfering to pin 71, and mercury 5 can not overflow in the slotted eye 11.

As conductive media matter, make transformer coil pin 71 and 3 conductings of flood line with mercury 5, guarantee the accurate test of characteristic tester transformer.Because mercury 5 density height, impurity can't mix with mercury 5, can only float on the surface of mercury 5, so this device has good contact performance, can select to use slotted eye on the pedestal by the specification of transformer in addition, thereby use flexible.
