Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer, in particular to a motor terminal mounting bracket. BACKGROUND

[0002] Compared with the traditional vehicle belt pulley compressor, the new energy vehicle adopts a full electric compressor. The compressor controls the built-in motor through the inverter integrated on the compressor to realize the driving of the compressor. First, the inverter receives strong and weak current and signal instructions from the system, and then delivers the modulated strong current to the motor through the inverter side wiring terminal, the wiring post sealed on the shell, the motor lead terminal and the motor lead.

[0003] The existing new energy full electric compressor generally installs the inverter on the rear shell integrated with the inverter mounting box. Therefore, a wiring post structure needs to be arranged on the rear shell, and the internal and external cavities are divided by sealing. Then, the integrated motor lead terminal is adopted to be connected to the wiring post in the compressor. At present, in order to facilitate manufacturing, the flange of the rear shell motor side is designed to be relatively low, so as to press the motor lead terminal into the wiring post of the rear shell by the outer edge of the motor. However, due to the too small axial size of the rear shell for distributing the effective volume, the middle shell must have a larger axial size to obtain the volume required for containing the motor and constituting the suction chamber. In order to obtain such a large size of the middle shell, a larger die casting machine needs to be used, which will lead to the increase of manufacturing cost. SUMMARY

[0004] The purpose of the present application is to provide a motor terminal mounting bracket to solve the above technical problems.

[0007] Preferably, the buckle mechanism comprises a first buckle and a second buckle arranged opposite to each other, the first buckle comprises a first mounting plate and a first clamping block, two first mounting plates are arranged at a preset included angle, one end of two first mounting plates is connected with one side surface of the bracket body, and a first clamping block is arranged between two first mounting plates, and the first clamping block is located at the other end of two first mounting plates.

[0008] As a further preferred, the second buckle comprises two second installation plates arranged at a preset included angle and two second clamping blocks connected with the two second installation plates.
