The top cover is provided with an electric connector 41, and the electric connector 41 is positioned at the outer side of the top cover and is close to the outer side of the top cover.
For better observation and adjustment of the position of the compressor stator placed on the stator placement support 2 inside the pseudo-housing 1, a transparent observation window for observing whether the stator lead is detached and whether the stator lead contacts the welded part of the pseudo-housing, a stator fixing hole for fixing the stator, and a housing end face angle scale 11 for measuring the angle formed between the stator lead position and the top cover electrical plug are provided on the pseudo-housing 1. The observation window set up in simulation casing 1's lateral wall, and be located simulation casing's upper portion, whether can be directly perceivedly observe the stator lead wire in the simulation casing and whether break away from and the stator lead wire contacts simulation casing's welded part through the observation window tester to simulate the actual assembly situation of compressor stator directly perceivedly truly, and whether the reservation length of this model of compressor stator lead wire is suitable is judged to the accuracy. The observation window is provided with a depth scale mark 12 for adjusting the position of the stator, and the position of the stator in the simulation shell 1 can be intuitively adjusted through the depth scale mark 12. The stator fixing holes are arranged on the inner side wall of the simulation shell 1, and the stator is fixed in the simulation shell 1 through the stator fixing holes.

In order to increase the practicability of the test device for testing the length of the stator lead of the compressor, the test device can test the lead lengths of compressors of different models (namely, angles between different stator leads and electric connectors), and the scale value of the shell end face angle scale 11 is 0-360 degrees, wherein the angle difference between every two adjacent scale values in the shell end face angle scale 11 arranged on the upper end face of the simulation shell 1 is 30 degrees, namely, the two adjacent scale values of the shell end face angle scale 11 are different by 30 degrees. When the stator is fixed in the simulation shell 1 and positioned on the stator placement support 2, the position of the stator lead corresponds to the position of 0 degree in the scale values of the shell end face angle scale 11, the output end of the stator lead is connected with the electric connector, then the electric connector is adjusted to the appointed scale value, and the length of the stator lead is tested.
