Abstract

The invention relates to a dry burning test device of a single-sided conductive PTC heating plate, and relates to the technical field of dry burning test devices. The device comprises a control unit which is configured to be used for outputting a control signal; a test unit which comprises a test carrying table and is configured to be in signal connection with the PTC heating plate and is in control connection with the control unit; a transfer unit which is in control connection with the control unit and is configured to transfer the PTC heating plate from a set position to the test carrying table; and an energy supply unit which comprises a test power supply for supplying power; wherein the conductive side of the PTC heating plate is provided with a forward electric connection end and a reverse electric connection end respectively, and the test carrying platform is provided with a first positive electrode connection end and a first negative electrode connection end close to the PTC heating plate and corresponding to the forward electric connection end and the reverse electric connection end respectively; abutting springs are arranged between the first positive electrode connectingend and the test carrying table and between the first negative electrode connecting end and the test carrying table, and the first positive electrode connecting end and the first negative electrode connecting end move in the length direction of the abutting springs. The device has the effect of improving the test efficiency.

Description

technical field [0001] The present application relates to the technical field of dry-burning test devices, in particular to a single-sided conductive PTC heating plate dry-burning test device. Background technique [0002] The PTC heater has the characteristic of constant temperature heating. The principle is that after the PTC heating plate is powered on, the self-heating temperature rises to make the resistance value rise and enter the transition zone. The surface temperature of the PTC heating plate will remain constant. The temperature is related to the applied voltage, but basically has nothing to do with the ambient temperature. [0003] Before the PTC heating plate leaves the factory, it is usually necessary to test the service life of the PTC heating plate. In the current related technology, it is usually realized by using a dry burning test device. The main purpose of the test is to consider the power attenuation of the PTC heating plate, 100 hours, 200 hours---100...
