Abstract
The invention relates to a resistivity measuring clamp for silver alloy wires. The resistivity measuring clamp comprises a pedestal (1), current terminals (3) and pressing bolts (4), wherein the current terminals (3) are symmetrically arranged on two sides of the upper end of the pedestal (1), lower end studs of the current terminals (3) penetrate through the pedestal (1) and locking nuts (2), a through hole (5) is transversely formed in the middle of each current terminal (3), the pressing bolts (4) are vertically arranged on the upper ends of the current terminals (3), the lower ends of the pressing bolts (4) are communicated with the through hole (5), and two potential terminals (6) are oppositely arranged on the pedestal (1) between clamping posts (3). The resistivity measuring clamp has the advantages of simple structure and convenience in assembly, thus a test on the resistivity of contact wires can be rapidly carried out, and the testing time is saved.
Description
Technical field
The present invention relates to the checkout equipment field of silver alloy, particularly relate to a kind of resistivity measurement fixture of silver alloy wire rod.
Background technology
The contact is a kind of part commonly used in present electrical industry, multiplex in the automatically controlled original papers such as relay, temperature controller, mostly present contact is to adopt silver alloy to make, because the electric conductivity requirement of contact is very high, therefore it is also very high that the electric conductivity of silver alloy requires, can be used at present representing that the physical quantity of material resistance characteristic is exactly resistivity, the electric conductivity of the lower expression material of resistivity is better.
The test formula of resistivity is ρ=RA/L, wherein L is the length of the wire rod of test, A is the area of section of wire rod, R is the resistance of the wire rod of certain-length, estimate in the resistivity of test material and need to measure length, area of section and resistance, but in large quantity ground test resistance rate, if do not have special test fixture to measure the workload that above-mentioned data will increase test greatly, and easily go wrong.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of resistivity measurement fixture of silver alloy wire rod, and is simple in structure, easy for installation, can test the resistivity of contact wire rod fast, saved the test duration.
