Contact resistance detection device and control method thereof

Abstract

The invention provides a contact resistance detection device, comprising: a test fixture, the test fixture comprising a turntable and a radial force sensor, the radial force sensor being mounted on the turntable; the control system comprises a controller, a driver and a resistance measuring module, the controller is connected with the radial force sensor, the driver and the resistance measuring module, and the controller obtains a radial force value monitored by the radial force sensor and controls the resistance measuring module to measure the radial force value. The controller controls the driver to drive the rotating disc and the radial force sensor to rotate, the application angle of the radial force is changed, and the resistance measuring module is connected with the inner cavity of the connector and the test needle through wires, measures the contact resistance value and sends the contact resistance value to the controller. The invention also provides a control method of the automatic mode and the manual mode of the device, the device can realize specified angle or 360-degree full-angle test and automatically record monitoring data, the working efficiency is high, the accuracy is high, and the device has good use and popularization values.

Description

technical field [0001] The invention relates to the field of contact resistance detection devices, in particular to a contact resistance detection device and a control method thereof. Background technique [0002] At present, there is an existing pharmaceutical industry standard "Dimensions and Test Requirements for Four-pole Connector System for Implantable Cardiac Rhythm Regulators for Active Implantable Medical Devices" (YY / T 0972—2016) that stipulates the requirements for the stability test of contact resistance , the standard requires that the test needle in the contact resistance test device can complete the 360° rotation test under the applied load. In the field of implantable medical devices, the contact resistance test device generally adopts a simple method of applying a load, such as by hanging a weight on the test needle to simulate the required load. The disadvantages are: 1. The load direction is single and can only simulate Load in one direction; 2. When chan...

Problems solved by technology

In the field of implantable medical devices, the contact resistance test device generally adopts a simple method of applying a load, such as by hanging a weight on the test needle to simulate the required load. The disadvantages are: 1. The load direction is single and can only simulate Load in one direction; 2. When changing the load direction, human intervention is required to manually rotate, the workload is large, the accuracy is poor, it is difficult to do a 360° full-angle test, and it cannot meet the industry standard 360° Stability test requirements
