Terminal protecting component of electric compressor

Abstract

The present terminal protecting component of an electric compressor is capable of ensuring jogged connection of a protuberance of a terminal cover relative to a blocking hole of a blocking sheet of a terminal protecting piece without great swinging after jogging even there is a micro size error. A protecting component (10) composed of the terminal protecting piece (4) fixed on a lid body (1a) andthe terminal cover (5) jogged and fixed on the terminal protecting piece (4) protects a terminal (2) mounted on the lid body (1a) of a closed container (1), wherein an upper end portion of the protuberance (8) formed on the terminal cover (5) is provided with an inclined plane (8) sloping downward for jogging in a blocking hole (7a) of a blocking sheet (7) formed on the terminal protecting piece (4), and a lower end portion is provided with an inclined plane (8b) sloping upward. Even though there is a micro size error between the blocking hole of the blocking sheet and the protuberance, it iscapable of ensuing the jogging connection of the protuberance without great swinging after jogging by absorbing the error by the inclined plane of the protuberance sloping downward.

Description

technical field [0001] The present invention relates to an electric compressor, and particularly relates to an improvement of a protection member for protecting a terminal attached to a closed container. Background technique [0002] Generally, an electric compressor houses a motor mechanism unit and a compression mechanism unit driven by the motor mechanism unit in an airtight container, and a terminal is installed in the airtight container. action. And, the gas (generally referred to as coolant) is introduced into the compression mechanism part through the introduction pipe and compressed, and at the same time, the high-pressure gas ejected from the airtight container is discharged to the outside through the discharge pipe. [0003] Such as Figure 4 As shown, the external electrode 2a of the terminal located outside the airtight container 1 is electrically connected to the connector 3a at the front end of a plurality of flexible wires 3 installed on the power supply side...

Problems solved by technology

[0010] However, if Figure 5 As shown in (a), it is difficult to grasp the size of the distance A from the lower edge of the terminal cover 5 to the upper edge of the protrusion 8 and the distance B from the upper surface of the substrate 4a of the terminal guard 4 to the upper edge of the engaging hole 7a, as Image 6 As shown, when the distance A is slightly greater than the distance B and an error C occurs, the lower edge of the terminal cover 5 has abutted against the bottom edge of the terminal guard 4 before the protrusion 8 fits into the engaging hole 7a of the locking piece 7 . Since the upper surface of the substrate 4a cannot be lowered any further, there is a problem that the protrusion 8 does not fit into the engaging hole 7a.

If the above-mentioned distance A is set to a size much smaller than the distance B, the situation that the protrusion 8 cannot be fitted into the engaging hole 7a can be prevented, but it is easy to make the terminal cover 5 unstable after being fitted.
