Abstract
The utility model discloses a converter for testing a pincer-shaped connecting wire direct current resistance tester. The converter for testing the pincer-shaped connecting wire direct current resistance tester comprises an insulation board. Four copper boards are symmetrically distributed on the insulation board, wherein two of the copper boards are arranged at the upper portion, and the other two of the copper boards are arranged at the lower portion. Four binding posts are arranged on four angles of the insulation board and the four binding posts are respectively C1, C2, P1 and P2, wherein the binding post C1 and the binding post P1 are respectively connected with two symmetrical copper boards arranged on the upper and lower side of the insulation board through a conducting wire, and the binding post C2 and the binding post P2 are respectively connected with the other two symmetrical copper boards arranged on the upper and lower side of the insulation board through a conducting wire. The converter can well solve the problems that a pincer-shaped wired direct current resistance tester can not carry out four-wire testing wire connection, wire connection is easy, working efficiency is improved, a contact area of a pincer jaw is enlarged, contact resistance is shortened and accuracy of testing is ensured by the set copper boards.
Description
Technical field
The utility model relates to the testing apparatus that a kind of pincerlike wiring directly hinders appearance (like SM333 type DCR of Transformer tester) usefulness, and especially a kind of pincerlike wiring directly hinders appearance and uses converter.
Background technology
In straight resistance appearance test process; Find that one type of straight resistance appearance connection terminal is pincerlike connector lug,, caused test wiring maybe can only insert from two current terminals because test is four-wire system with the measuring resistance wiring; Thereby introduced the connection resistance of current terminal, made measurement result inaccurate.
The utility model content
The technical matters that the utility model will solve provides a kind of easy to operate, pincerlike accurately and reliably wiring of test result and directly hinders the appearance test and use converter.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of pincerlike wiring directly hinders the appearance test and uses converter; Its gordian technique is: comprise an insulcrete; On said insulcrete, be inlaid with four copper coins of mutually insulated; Said four copper coins are respectively equipped with binding post by being symmetrically distributed on the insulcrete for twice on two on four angles of said insulcrete, said four binding posts are respectively C1, C2, P1, P2; Wherein binding post C1 and binding post P1 respectively through lead be positioned at insulcrete up and down the copper coin of two symmetries of both sides join, binding post C2 and binding post P2 respectively through lead be positioned at insulcrete up and down other copper coin of two symmetries of both sides join.
Adopt the beneficial effect that technique scheme produced to be: adopt this converter can well solve pincerlike wiring and directly hinder the problem that appearance can't carry out four-wire system test wiring, and wiring to be simple, has improved work efficiency; Increase the contact area of jaw through the copper coin that is provided with, reduced contact resistance, guaranteed the accuracy of test.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model comprises an insulcrete 2, on said insulcrete 2, is inlaid with four copper coin 1 (resistivity 1.75 * 10 of mutually insulated
-8Ω rice), four copper coins 1 are respectively equipped with binding post by being symmetrically distributed on the insulcrete 2 for twice on two on four angles of said insulcrete 2; Said four binding posts are respectively C1, C2, P1, P2; Wherein binding post C1 and binding post P1 join through lead 3 and the copper coin 1 that is positioned at insulcrete two symmetries of both sides 2 about respectively, binding post C2 and binding post P2 respectively through lead and be positioned at insulcrete about in the of 2 other copper coin of two symmetries of both sides join, C1 and P1 are one group; C2 and P2 are one group; Be labeled as C1P1 and C2P2, same group binding post is positioned at the same end of insulcrete, up and down symmetry.Lead 3 is wanted firm welding with copper coin 1.
The method of application of the utility model is following:
1, chooses the measuring resistance of test usefulness earlier by working current and amount limit;
2) by four-wire system wiring requirement (C
1C
2P
1P
2) connect measuring resistance and this converter.
3) by four-wire system wiring requirement (C
1C
2P
1P
2) two jaws that pincerlike wiring is directly hindered appearance clip on the copper coin of this converter; Be drawn out to four pincers faces of jaw respectively on four binding posts through four copper coins 1 on the converter, be connected with standard device (being measuring resistance) through binding post.
4) start test, through gathering voltage end (P
1P
2) electric current exported on the voltage ratio is calculated the test resistance value, thereby reading of data.
The utility model clips to jaw on four copper coins according to four-wire system, thereby draws wiring, makes things convenient for the access of measuring resistance, and is very easy to use.
