Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the socket used to connect the lead wire of the existing electric compressor motor is in a floating state, which cannot be effectively positioned and is prone to failure due to unreliable connection or damage (squeezed) of the lead wire. This leads to problems such as poor contact or electrical breakdown. A method for positioning the DC brushless motor socket on the outer surface of the stator for scroll electric compressors is invented.

Embodiment 1

[0036] Such as Figure 1~6 shown.

[0037] A method for positioning a DC brushless motor socket on the outer surface of a stator for a scroll electric compressor, comprising the following steps:

[0038] Firstly, a dovetail-shaped boss 2 is provided on the side of the socket 1 close to the stator core; at the same time, on the side of the socket in contact with the stator core, at least one dovetail-shaped boss is provided on each side for resisting Hold the claws 3 on the surface of the stator core to prevent the socket from shaking in the circumferential direction on the circumference of the stator core after being inserted into the dovetail slot, such as Figure 4~6 shown;

[0039] Secondly, the dovetail groove 5 matching the dovetail-shaped boss is punched out at the same position of the part of the stator punch that forms the stator core, while the corresponding position of the other part of the stator punch has no dovetail groove structure or other structures t...

Embodiment 2

[0043] Such as Figure 1-12 shown.

[0044] A method for positioning a DC brushless motor socket on the outer surface of a stator for a scroll electric compressor, comprising the following steps:

[0045] First, a dovetail-shaped boss 2 is provided on the side of the socket 1 close to the stator core; on the side of the socket in contact with the stator core, at least one dovetail-shaped boss is provided on each side for resisting Hold the claws 3 on the surface of the stator core to prevent the socket from shaking in the circumferential direction on the circumference of the stator core after being inserted into the dovetail slot, such as Figure 4~6 ;

[0046] Secondly, the dovetail slot matching the dovetail-shaped boss is punched out on the stator punching sheet that forms the stator core, and there is no dovetail-groove structure at a position adjacent to the dovetail slot at a certain angle (such as 180o) or other structures that cannot make the dovetail-shaped boss...

Abstract

A method for enabling a brushless direct current motor socket for a vortex type electric compressor to be located on a stator excircle surface is characterized by comprising the steps of first arranging a dovetail-shaped boss (2) on one side of the socket (1) adhering to a stator core; then enabling a dovetail groove matched with the dovetail-shaped boss to be stamped at the same position of stator punching pieces forming the stator core; enabling part of stator punching pieces stamped with the dovetail groove to be stacked and then form a dovetail groove for the dovetail-shaped boss to be inserted, and enabling a blocking structure to be formed at the same position of another part of stator punching pieces; enabling the socket with a motor outgoing line to be inserted into the dovetail groove, achieving location of the socket along the other end in the axial direction by means of the outgoing line (4) and deformation force and the length of the outgoing line (4), and enabling the socket to be located on the stator core. The method has reliability in location and convenience in connection, and in the integrated vortex type electric compressor, a motor is accurately and reliably connected with a controller.

Description

technical field [0001] The invention relates to a brushless DC motor technology in an electric compressor, in particular to a method for installing a DC brushless motor socket on the outer surface of a stator for a scroll electric compressor, in particular to an electric compression motor The positioning method of the socket on the outer surface of the stator. Background technique [0002] At present, in the scroll electric compressor, the motor and the controller are respectively installed on the inner and outer sides of the sealed casing, and the connection needs to be through a plug. One end of the plug (conductive post) on the plug is connected to the controller socket, and the other One end is connected to the motor lead wire socket. And at present all adopt first fixing plug and then install motor lead wire socket, the method for sealing compressor shell at last, thereby can guarantee that controller and motor are reliably connected. However, this kind of integrated ...
