Japanese Laid-Open Patent Publication No. 2015-40538

By the way, in recent electric compressors, it is desired to use the metal material which has high heat resistance with use of the electric power larger than the prior art. However, since a metal material with high heat resistance is not easily welded, there exists a possibility that productivity may fall in the welding operation in a connector.

The present invention has been made in order to solve the above problems, and an object thereof is to provide an electric compressor capable of improving the productivity of a connector.

An electric compressor for solving the above problems includes: a compression unit for compressing a fluid; an electric motor for driving the compression unit; an inverter device for driving the electric motor and having a circuit board; and a motor housing for accommodating the electric motor A housing having a seal, an inverter accommodating chamber accommodating the inverter device, and a partition wall dividing the motor accommodating chamber and the inverter accommodating chamber, and a conductive pin penetrating through the partition wall and having one end electrically connected to the electric motor and a connector disposed in the inverter accommodating chamber and electrically connecting the other end of the conductive pin and the circuit board, the connector comprising: a metal connector body; It has a case and is disposed between the circuit board and the partition wall, wherein the connector body has a terminal portion into which the other end of the conductive pin is inserted and withdrawn, and a connection portion for electrically connecting the terminal portion and the circuit board. In the motor-driven compressor, the connector body is formed by bending and deforming an integral metal plate, and the terminal part has a pair of clamping parts facing each other and clamping the conductive pin, and the connecting part is It is characterized in that it has a protrusion that is inserted and passed through the circuit board while protruding to the outside.

According to the above configuration, the connector main body is made of an integral metal plate continuous from the clamping portion to the protruding portion. In this way, since the connector main body can be formed of an integral metal plate, welding becomes unnecessary in the manufacture of the connector. Therefore, the productivity of the connector can be improved.

In the motor-driven compressor, the terminal portion includes a connecting portion connecting each of the pair of clamping portions, and the pair of clamping portions are separated from each other by engaging each other on the opposite side to the connecting portion with respect to the pair of clamping portions. It is preferable to have a pair of engaging parts which restrain so as not to lose.

According to the said structure, a pair of clamping part clamps an electrically conductive pin more firmly by a connection part and an engaging part, and the connection of an electrically conductive pin and a connector is stabilized.

In the motor-driven compressor, it is preferable that the connecting portion has an extended formed portion accommodated inside the case while connecting the terminal portion and the protruding portion, and the extended formed portion has a bent portion.

In an environment in which the motor-compressor vibrates, if the motor-compressor vibrates and the circuit board tries to move, stress may be applied to the connector body. According to the above configuration, since the stress applied to the connector body can be attenuated in the bent portion of the extension forming portion, the durability of the connector against vibration can be improved.

In the electric compressor, it is preferable that the said conductive pin has a copper layer on the surface, and the said metal plate is a copper plate.

According to the said structure, since a conductive pin and the same copper part contact each other, contact resistance can be suppressed. Accordingly, it is possible to supply greater electric power from the inverter device to the electric motor.

ADVANTAGE OF THE INVENTION According to this invention, productivity of a connector can be improved.

Accordingly, the productivity of the connector 49 can be improved.

(2) The terminal portion 51 is formed by engaging the connecting portion 56 connecting each of the pair of clamping portions 53 and the pair of clamping portions 53 on the opposite side to the connecting portion 56 by engaging with each other. It has a pair of engaging parts 57 which restrain so that a pair of clamping parts 53 may not mutually separate.

Therefore, even if stress is applied to the connector main body 50 accompanying the vibration of the motor-driven compressor 10, the applied stress can be attenuated in the bent portion 85, so that the durability of the connector 49 against vibration is improved. can be improved

(4) The conductive pin 27 has a copper layer 27b on the surface, and the connector body 50 is made of a copper plate. Therefore, since the conductive pin 27 and the clamping part 53 come into contact with the same copper comrades, contact resistance can be suppressed. Accordingly, large electric power can be supplied from the inverter device 30 to the electric motor 17 .

(5) Since there is no welding point in the connector body 50, the durability of the connector body 50 with respect to the stress applied to the connector body 50 accompanying vibration of the electric compressor 10 can be improved. .

(6) Since it is not necessary to form the overlapping of members necessary for welding in the connector main body 50, the connector main body 50 can be downsized by the amount which can abbreviate|omit the overlapping of members. Further, since there is no need for a space for inserting the electrode used for welding to the connector body 50 inside the case 60, the case 60 can be downsized by the amount that can be omitted. Accordingly, the overall size of the connector 49 can be reduced in size.

(7) The base material 150 molded using the same punching type|mold is used for manufacture of the 1st connector main body 50a, the 2nd connector main body 50b, and the 3rd connector main body 50c. Therefore, since the number of steps involved in molding the substrate 150 can be reduced compared to the case of using a punching die having a different shape for molding the substrate 150 for each connector main body 50 , Productivity can be further improved.
