The invention discloses a contact resistance test clamping device based on a pressure adjustment clamping area and a number. The device comprises a box body, a first screw transmission mechanism, a first clamping arm, a second screw transmission mechanism, a second clamping arm, a third screw transmission mechanism, a third clamping arm, a fourth screw transmission mechanism, a sample groove body,a top cover and a bottom cover. The first screw transmission mechanism and the second screw transmission mechanism are connected to the first clamping arm and the second clamping arm respectively. The third screw transmission mechanism is connected to the third clamping arm. The second clamping arm is provided with a movable plate and the fourth screw transmission mechanism. The top surface of the box body is provided with a groove body port used for installing the sample groove body. The side wall of the box body is provided with an insertion sheet and a plurality of insertion sheet holes cooperated with the insertion sheet. Through the insertion sheet and the insertion sheet holes, the height of the sample groove body is positioned. In the invention, metal samples with different areas and different sheet numbers can be clamped so as to carry out contact resistance testing. A clamp does not need to be replaced frequently, a repetition utilization rate is high, the structure is simple, an application prospect is wide and the device is easy to popularize.
Description
technical field [0001] The invention belongs to the technical field of superconductivity, and in particular relates to a clamping device for contact resistance testing which adjusts the clamping area and quantity based on pressure. Background technique [0002] Contact resistance is the resistance presented between conductors. In the process of testing contact resistance, a contact resistance clamping device is often used. The clamping device is mainly used to realize the connection between the test electrode and the press. [0003] The existing contact resistance clamping device can only clamp metal samples with a fixed area and a fixed number of pieces, but when measuring metal samples with different areas and different quantities, it cannot be realized by a single fixture, and it needs to be determined according to the test sample. Frequent replacement of jigs in terms of area and quantity, on the one hand, makes the reusability of the contact resistance jig low, and on t...
