Description
Technical field
The present invention relates to the detection apparatus field of silver alloy, particularly relate to the resistivity measurement fixture of a kind of silver alloy wire rod.
Background technology
Contact is a kind of part conventional in current electrical industry, is used in the automatically controlled original paper such as relay, temperature controller, at present
Contact be mostly use silver alloy make, owing to the conduction needs of contact is the highest, thus the electric conductivity of silver alloy want
Ask the highest, can be used for representing that the physical quantity of material resistance characteristic is exactly resistivity at present, leading of resistivity the lowest expression material
The best.
The test formula of resistivity is ρ=RA/L, and wherein L is the length of the wire rod tested, and A is the area of section of wire rod, and R is
The resistance of the wire rod of certain length, estimates and needs to measure length testing the resistivity of material when, area of section and resistance,
But big quantity ground test resistance rate when, measuring above-mentioned data without special test fixture will increase
Add the workload of test, and easily go wrong.
Summary of the invention
The technical problem to be solved is to provide the resistivity measurement fixture of a kind of silver alloy wire rod, simple in construction, peace
Dress is convenient, quickly can test the resistivity of contact wire rod, save the testing time.
The technical solution adopted for the present invention to solve the technical problems is: provide the resistivity measurement of a kind of silver alloy wire rod to press from both sides
Tool, including base plate, current terminal and hold-down bolt, the upper end lateral symmetry of described base plate is provided with current terminal, described
The lower end stud of current terminal through base plate and locking nut, the intermediate lateral of described current terminal has through hole, described
The upper end of current terminal hold-down bolt is vertically installed, the lower end of described hold-down bolt communicates with through hole, described electric current
Being mounted opposite two current potential terminals on base plate between terminal, described current potential terminal is fixed by screws on base plate, institute
The current potential terminal stated is L-shaped, described screw arrangement at the middle part of current potential terminal horizontal component, the height of described current potential terminal
Degree is lower identical along height with through hole.
Described base plate, current terminal, hold-down bolt and locking nut is all to adopt to be made from an insulative material.
The described distance between current potential terminal is at least 300mm, between the current terminal that described current potential terminal is adjacent
