Problems solved by technology

[0004] However, in the existing technology, for the abnormal phenomenon of the motor, the motor is usually detected through other detection circuits, which cannot immediately reflect whether the stator connector is in a normal state, and cannot detect from the source, and in the traditional technology , the stator connector is not used to detect the temperature around the motor to judge whether the motor is running normally, which leads to the abnormal output voltage and temperature of the motor directly acting on the stator connector, and the damage of the stator connector will further increase the motor’s damage. Abnormal, causing damage to the motor

Embodiment 1

[0034] like Figure 1-6As shown, this embodiment relates to a stator connector withstand voltage test fixture with a thermistor, including a fixing frame 1; The fixed seat 2 fixes the stator connector 5 horizontally; the infrared thermal imager 3, the infrared thermal imager 3 is placed under the fixed frame 1, and the infrared thermal imager 3 is provided with a thermistor 51 surface temperature for detecting the stator connector 5 The detection head 31; the PIN needle connector 4, the PIN needle connector 4 is movably connected to the stator connector fixing seat 2 through a pressing device 6, and the PIN needle connector 4 is provided with multiple PIN needles 41, and multiple PIN needles 41 The pin 41 is crimped with the corresponding conductive terminal 52 on the stator connector 5 .

[0035] By adding a thermistor 51 to detect the temperature next to the motor after the actual stator connector 5 is installed, it is judged whether the motor is working abnormally, so as t...

Embodiment 2

[0048] A test method for a stator connector withstand voltage test fixture with a thermistor, comprising the following steps:

[0049] S1. Insert the toggle block 255 into the through hole 2541, push the toggle block 255 to drive the support rod 2542 to move horizontally, the support rod 2542 drives the slider 254 to move, and the slider 254 drives the buckle block 251 through the first connecting plate 252 Move away from the receiving block 24 side.

[0050] At this time, it is equivalent to opening the entire snap-fit ​​limiting structure, which is convenient for the stator connector 5 to be put in.

[0051] S2. Drive the pressing device 6 to lift the PIN needle connector 4 .

[0052] In this step, specifically: drive the first air cylinder 62 to lift the support plate 61 , and then lift the PIN pin connector 4 . The movement of the buckle block 251 is to free up space in the horizontal direction, and then lift the PIN pin connector 4 to free up space in the vertical direc...

Abstract

The invention discloses a withstand voltage test fixture for a stator connector with a thermistor and a test method of the withstand voltage test fixture. The fixture comprises a fixing frame, a stator connector fixing seat which is arranged below the fixing frame, and the stator connector fixing seat is used for horizontally fixing the stator connector; an infrared thermal imager which is provided with a detection head used for detecting the surface temperature of the thermistor of the stator connector; and a PIN connector which is movably connected to the stator connector fixing seat through a pressing device, a plurality of PINs are arranged on the PIN connector, and the PINs are used for being connected with the corresponding conductive ends on the stator connector in a pressing manner. The surface temperature of the additionally arranged thermistor is detected through the infrared thermal imager, the resistance value range of the thermistor is determined, the accuracy of the thermistor is detected through the actual resistance value measured through external connection of the PIN connector, the PIN connector is further externally connected with all the conductive ends on the stator connector, and the voltage resistance of the conductive ends is detected.

Description

technical field [0001] The invention relates to the field of test jigs for stator connectors, in particular to a jig for withstand voltage testing of stator connectors with a thermistor and a testing method thereof. Background technique [0002] With the development of science and technology, in response to the policy of energy conservation and emission reduction, new energy vehicles have gradually appeared on the market. New energy vehicles are usually driven by rotor motors. The drive of the rotor motor requires a power supply. In order to facilitate the control connection of the rotor motor, the power line and control line of the rotor motor are converged by setting the stator connector. The power supply only needs to be directly connected to the stator connector to realize the control of the rotor motor. , reducing the line connection steps. [0003] As the external equipment of the motor, the stator connector will be installed next to the motor. The motor will genera...
