Embodiment Construction

[0038] Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

[0039] figure 1 It is a figure showing the structure of the electric compressor (integrated electric compressor) 10 of this embodiment.

[0040] Such as figure 1 As shown, the electric compressor 10 accommodates an electric motor (not shown) and a scroll compressor (not shown) in the lower housing chamber 11a of the housing 11, and accommodates it in the upper housing chamber 11b of the housing 11 opened upward. Inverter substrate (control substrate) 12 . The opening facing upward of the upper storage chamber 11 b of the casing 11 is covered with a cover 17 .

[0041] The inverter board 12 includes: a capacitor 13 and a reactor 14 for smoothing the DC voltage input to the inverter board 12; a control circuit board 15 for controlling application of high-voltage AC current to the motor; The DC power is converted into AC power and applied to the motor to dri...

Abstract

The present invention provides an integrated electric compressor which is improved in reliability. Bus bar connection is employed in each electrical connection between a power board (16) and the power supply side and between the power board (16) and the motor side, and welding is employed for bonding the bus bar to a capacitor (13) and a reactor (14), and for bonding the board side terminal of the bus bar to the PN terminals (20a, 20b), the UVW terminals (25a, 25b, 25c) and the housing side terminals (28a, 28b, 28c). The terminals can be mutually bonded with stabilized quality by using resistance welding. Furthermore, since a planar bonding plate is provided on one end side of the housing side terminals (28a, 28b, 28c) and the UVW terminals (25a, 25b, 25c) are welded thereto, reliable mutual bonding of terminals can be attained.

Description

technical field [0001] It relates to an integrated electric compressor constituting a vehicle air conditioner. Background technique [0002] In recent years, there has been provided an integrated electric compressor in which a compressor constituting an in-vehicle air conditioner, a motor for driving the compressor, and a drive board for driving the motor are integrally housed in a housing (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Patent No. 3086819 [0004] It is not limited to this kind of integrated electric compressor, but the heat and vibration conditions of automotive parts are far stricter than those of machines in other fields. In the integrated electric compressor, since the drive board on which electric / electronic components are mounted is housed in the casing together with the compressor and the motor, it is particularly required to improve the reliability of the drive board. [0005] As is well known, soldering or screws ...
