Description

High voltage connector assembly and electric compressor including the same

The present invention relates to a high voltage connector assembly and an electric compressor including the same, and more specifically, a high voltage connector assembly having a structure in which the high voltage connector and the housing can be easily connected, and leakage and leakage of current through the high voltage connector can be prevented. And to an electric compressor including the same.

Compressors that compress refrigerants in vehicle air conditioning systems have been developed in various forms. In recent years, according to the trend of electrification of automobile parts, the development of electric compressors driven by electricity using a motor has been actively made.

A scroll compression method suitable for high-compression ratio operation is mainly applied to an electric compressor. Such a scroll type electric compressor (hereinafter referred to as "electric compressor") is composed of an electric unit, a compression unit, and a rotating shaft connecting the electric unit and the compression unit.

Specifically, the electric unit is provided with a rotary motor or the like and installed inside a sealed casing. The compression unit is located on one side of the electric unit, and consists of a fixed scroll and an orbiting scroll. The rotation shaft is configured to transmit the rotational force of the electric unit to the compression unit.

The rotary motor is configured to receive power and control signals from an external power source such as a battery and a control unit. To this end, the rotary motor is connected to an external power source and a control unit (hereinafter referred to as "power source") so as to be energized. The above energization can be achieved by a energizing member such as a conducting wire.

At this time, when the electric compressor is operated, vibration may be generated in the electric compressor by rotation of the rotary motor and the orbiting scroll. In the case of a connection using a wire or the like, there is a fear that the energized state between the electric compressor and the power source may be arbitrarily released due to the vibration.

Accordingly, in order to connect the electric compressor to a power source, etc., a connector is generally used.

1 and 2, a connector 1000 provided in an electric compressor according to the prior art is shown.

The connector 1000 according to the prior art is configured to connect an inverter device and a rotary motor accommodated in the electric compressor so as to energize an external power source or the like.

The connector 1000 includes a cover part 1100 and a connector part 1200 made of aluminum (Al). The connector unit 1200 is configured to shield noise from a filter unit (not shown) to which the conductive wire 1800 is energized.

The connector part 1200 is inserted into a space formed inside the cover part 1100. Specifically, the connector unit 1200 is inserted and coupled to the cover unit 1100 through an insertion unit 1300 formed as an opening at one side of the cover unit 1100.

When the connector part 1200 is inserted, the plate 1300, the sealing part 1400, and the wire coupling part 1500 are sequentially inserted into the space. Thereafter, the bracket 1600 is fastened to the cover portion 1100 by a bolt 1700.

To this end, a bolt fastening groove 1200 is recessed in the cover part 1100. In addition, a bolt fastening hole 1620 is formed through the bracket 1600 at a position corresponding thereto.

When the above process is completed, the connector 1000 is fastened to the electric compressor. Specifically, in the connector 1000, a separate fastening member (not shown) is penetrated through each fastening hole 1110 formed through the cover part 1100 to be fastened to the electric compressor.

Thereafter, the conducting wire 1800 is inserted into the connector 1000. The conductive wire 1800 is electrically connected to the connector part 1200 through a through hole formed in the conductive wire through part 1610 and the plate 1300.

As described above, the connector 1000 according to the prior art requires many members for manufacturing. Accordingly, the production cost and number of hours for manufacturing each member are increased. In addition, as many members are provided, there is a problem that the weight of the connector 1000 is increased.

In addition, if the members are not airtightly assembled with each other, there is a risk that current may leak through a gap between the members. When an electric compressor is provided in a vehicle or the like, there is also a possibility that moisture may be introduced through the gap to cause a malfunction of the electric compressor.

Furthermore, the connector 1000 is connected to an electric compressor receiving a member rotating therein. Accordingly, there is a concern that various members provided in the connector 1000 may be damaged by the vibration due to the vibration generated by the electric compressor or the coupled state may be released.

The plate protrusion 560 is configured to increase the surface area of the plate outer circumferential portion 529. Accordingly, a gap due to a difference in thermal expansion coefficient between the cover portion 510 and the shielding plate portion 520 can be minimized. In addition, the bonding force between the cover portion 510 and the shielding plate portion 520 may also be improved.

In addition, the plate protrusion 560 is configured to form a more complex surface of the plate outer circumferential portion 529. Accordingly, the coupling force between the cover portion 510 and the shielding plate portion 520 may be improved compared to a case where the surface of the plate outer circumferential portion 529 is formed on a single smooth surface.

Due to the plate protrusion 560, the shielding plate portion 520 can stably maintain a state in which the opening 511b of the cover portion 510 is shielded.

Accordingly, external water or dust does not flow into the space part 514 of the cover part 510, so that a energized state between the high voltage cable 20 and the filter conduction part 410 can be stably maintained.

A plurality of plate protrusions 560 may be provided. The plurality of plate protrusions 560 may be continuously disposed apart from each other by a predetermined distance along the outer circumference of the plate 529.

The space formed between the plurality of plate protrusions 560 may compensate for an increase in volume due to thermal expansion of the cover part 510 or the shielding plate part 520.

In the illustrated embodiment, the plate protrusion 560 includes a first plate protrusion 560a and a second plate protrusion 560b.

The first plate protrusion 560a is formed to protrude from one side of the shield plate body 521 by a predetermined distance. The second plate protrusion 560b is formed to protrude by a predetermined distance from the other side of the shielding plate body 521 facing the one side.

The protrusion distances of the first plate protrusion 560a and the second plate protrusion 560b may be changed according to the shape of the cover part 510.

Specifically, the cover part 510 faces the first surface 511d and the first surface 511d on which the opening 511b is formed, and is spaced apart from the first surface 511d by a predetermined distance to form the space part 514. It may include a second surface 511e formed to surround it.

The outer circumferential portion 529 of the plate is inserted into a space formed between the first surface 511d and the second surface 511e to contact the inner circumferential portion 511c.

In this case, the first plate protrusion 560a and the second plate protrusion 560b may be formed such that the sum of the protrusion distances is equal to a predetermined distance between the first and second surfaces 511d and 511e. .

In an embodiment, the first plate protrusion 560a and the second plate protrusion 560b may be formed to protrude by the same distance. In the above embodiment, since the center of gravity of the shielding plate part 520 is located in the center of the space, the shielding plate part 520 can stably maintain a coupled state.

The first plate protrusion 560a and the second plate protrusion 560b each include a first protrusion surface 561, a second protrusion surface 562, and a third protrusion surface 563.

The first protruding surface 561 extends from the outer circumferential portion 529 of the plate to form a predetermined angle with the outer circumferential plate 529. In one embodiment, the first protruding surface 561 may extend perpendicularly to the outer circumferential portion 529 of the plate.

The second protruding surface 562 extends from the first protruding surface 561 to form a predetermined angle with the first protruding surface 561. In an embodiment, the second protruding surface 562 may extend perpendicular to the first protruding surface 561. In addition, the second protruding surface 562 may extend parallel to the outer circumferential portion 529 of the plate.

The third protruding surface 563 extends from the second protruding surface 562 to form a predetermined angle with the second protruding surface 562. In one embodiment, the third protruding surface 563 may extend perpendicular to the second protruding surface 562. In addition, the third protruding surface 563 may extend parallel to the first protruding surface 561.

The other side of the second protruding surface 562, that is, one side facing the second protruding surface 562, extends to the outer peripheral portion 529 of the plate.

The plate protrusion 560 may have any shape capable of increasing the surface area of the plate outer circumferential part 529 and a contact area with the inner circumferential part 511b.

(7) Description of the uneven portion 570

Referring to FIG. 8, the high voltage connector assembly 500 according to an embodiment of the present invention includes an uneven portion 570.

The uneven portion 570 is configured to increase the surface area of the outer peripheral portion 529 of the plate. Accordingly, a gap due to a difference in thermal expansion coefficient between the cover portion 510 and the shielding plate portion 520 can be minimized. In addition, the bonding force between the cover portion 510 and the shielding plate portion 520 may also be improved.

In addition, the uneven portion 570 is configured to form a more complex surface of the outer peripheral portion 529 of the plate. Accordingly, the coupling force between the cover portion 510 and the shielding plate portion 520 may be improved compared to a case where the surface of the plate outer circumferential portion 529 is formed on a single smooth surface.

By the uneven portion 570, the shielding plate portion 520 can stably maintain a state in which the opening 511b of the cover portion 510 is shielded.

Accordingly, external water or dust does not flow into the space part 514 of the cover part 510, so that a energized state between the high voltage cable 20 and the filter conduction part 410 can be stably maintained.

The uneven portion 570 is formed on the outer peripheral portion 529 of the plate. Specifically, the uneven portion 570 is continuously formed along the plate outer peripheral portion 529.

The uneven portion 570 includes a convex portion 571 and a concave portion 572.

The convex portion 571 is formed to protrude from the outer peripheral portion 529 of the plate by a predetermined distance. The concave portion 572 is formed to be recessed by a predetermined distance from the plate outer peripheral portion 529. The convex portion 571 and the concave portion 572 are formed alternately and continuously along the plate outer circumferential portion 529.

In the illustrated embodiment, the convex portion 571 and the concave portion 572 have a semicircular cross section. The convex portion 571 and the concave portion 572 may have any shape capable of achieving the above-described object.

4. Description of the coupling structure of the high voltage connector assembly 500 and the electric compressor 10 according to an embodiment of the present invention

Hereinafter, a coupling structure between the high voltage connector assembly 500 and the electric compressor 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. 9 to 11. As described above, the high voltage connector assembly 500 is coupled to the front housing 300.

Specifically, the high voltage connector assembly 500 is coupled to the connector coupling portion 330 of the front housing 300. In the space enclosed by the connector coupling part 330, the filter receiving part 340 is recessed by a predetermined distance.

First, the EMC filter 400 is inserted and coupled to the filter receiving portion 340. The EMC filter 400 accommodated in the filter accommodating part 340 is connected to an inverter device (not shown) to be energized.

When the EMC filter 400 is inserted into the filter receiving part 340, one end of the filter conducting part 410 protrudes outward. The end of the filter conducting part 410 is connected to the high voltage cable 20 so as to be energized.

The high voltage cable 20 is coupled to the high voltage connector assembly 500. Specifically, the high voltage cable 20 is sequentially inserted through the holder through hole 552, the cable insertion hole 542, and the cable through hole 532.

The high voltage cable 20 may be inserted into the high voltage connector assembly 500 until one end of the high voltage cable 20 reaches the EMC receiving portion 518.

Although not shown, a conductive member formed of a conductive material is provided at one end of the high voltage cable 20. The energizing member may be connected to the filter energizing part 410 to be energized. In one embodiment, the current-carrying member may have a hollow portion formed therein to allow the filter-carrying part 410 to be energized and coupled thereto.

Now, the high voltage connector assembly 500 is coupled to the front housing 300.

One end of the filter conducting part 410 passes through the EMC through part 528 and is accommodated in the EMC receiving part 518. At this time, the current-carrying member of the high voltage cable 20 is positioned in the EMC receiving part 518. Accordingly, one end of the filter conducting part 410 is connected to the conducting member of the high voltage cable 20 so as to be energized. In one embodiment, the filter conducting part 410 may be inserted and coupled to the conducting member so as to be energized.

Next, the high voltage connector assembly 500 is fastened to the front housing 300 by a fastening member (not shown).

Specifically, the fastening member (not shown) penetrates each cover fastening hole 513a, 513b, 513c formed in the cover part 510 and each shielding fastening hole 523a, 523b, 523c formed in the shielding plate part 520 Are combined.

One end of the fastening member (not shown) facing the front housing 300 is inserted into a recessed portion (not shown) formed in the connector coupling portion 330. In one embodiment, the fastening member (not shown) may be provided as a screw member. In addition, a thread may be formed on the inner circumferential surface of the depression (not shown).

5. Description of the effects of the high voltage connector assembly 500 and the electric compressor 10 according to the embodiment of the present invention

The cover portion 510 and the shielding plate portion 520 of the high voltage connector assembly 500 according to the embodiment of the present invention are integrally formed. In one embodiment, the cover portion 510 and the shielding plate portion 520 may be formed by a method of double injection molding or insert injection molding.

Therefore, compared to the case of manufacturing and combining the cover portion 510 and the shielding plate portion 520 respectively, manufacturing cost and time may be reduced. In addition, since the cover portion 510 and the shielding plate portion 520, which were performed by hand, are integrally formed, the process can be simplified.

Furthermore, the shielding plate portion 520 is not moved or swinging while being coupled to the cover portion 510. Accordingly, the shielding plate portion 520 may maintain a state disposed at an optimal position for shielding an electrical noise signal generated from the EMC filter 400. Accordingly, the shielding effect of the electrical noise signal may be improved.

Other components of the high voltage connector assembly 500, for example, the support plate portion 530 and the sealing portion 540 are inserted and coupled to the cover portion 510. In addition, the holder part 550 is coupled to the cover part 510 to maintain the inserted state of the members.

Therefore, a separate fastening member is not required to manufacture the high voltage connector assembly 500. Accordingly, the number of members constituting the high voltage connector assembly 500 may be reduced. In addition, since the fastening member is unnecessary, a gap that may occur at the fastening portion does not occur.

The cover part 510 and the holder part 550 may be coupled by a snap fastening method. That is, for the coupling of the cover part 510 and the holder part 550, there is no need to provide a separate fastening member.

Accordingly, it is possible to easily form a combined state of the cover part 510 and the holder part 550. In addition, as the fastening member is excluded, a gap that may occur at the fastening portion does not occur. Furthermore, by snap fastening, the coupling state of the cover part 510 and the holder part 550 may be stably maintained unless a separate external force is applied.

In addition, a decrease in the number of members constituting the high voltage connector assembly 500 means a decrease in the number of contact points between each member.

Accordingly, the clearance that may occur at the contact portion between each member can be reduced. In addition, due to the vibration generated as the electric compressor 10 is operated, vibrations or shocks applied to each other by contacting members may be reduced. Accordingly, durability against vibration of the high voltage connector assembly 500 may be improved.

Further, in an embodiment, the outer circumferential portion 529 of the plate may be formed to have a relatively larger roughness than the inner circumferential portion 511c of the cover portion 510.

Accordingly, the frictional force between the outer circumferential portion 529 and the inner circumferential portion 511c of the plate is increased, so that the coupling state of the shielding plate portion 520 and the cover portion 510 can be stably maintained. Therefore, even if the shielding plate portion 520 and the cover portion 510 are thermally expanded to different volumes, the distance between the outer peripheral portion 529 and the inner peripheral portion 511c of the plate can be minimized. As a result, the space in which leakage or leakage may occur can be minimized.

In addition, in another embodiment, a plurality of plate protrusions 560 may be formed on the outer circumferential portion 529 of the plate. The plurality of plate protrusions 560 are spaced apart from each other by a predetermined distance, and are disposed in plurality along the outer circumferential portion 529 of the plate.

Accordingly, the contact area between the outer peripheral portion 529 and the inner peripheral portion 511c of the plate may be increased. Accordingly, a contact force between the shielding plate portion 520 and the cover portion 510 may be improved.

In addition, the volume increase due to thermal expansion of the cover portion 510 and the shielding plate portion 520 is compensated by a space formed by the plurality of plate protrusions 560 spaced apart from each other.

As a result, as the cover part 510 and the shielding plate part 520 are separated from each other, the size of the space formed may be minimized. Accordingly, leakage or leakage that may occur through the space can be minimized.

In addition, in another embodiment, an uneven portion 570 may be formed in the outer peripheral portion 529 of the plate. In the uneven portion 570, the convex portion 571 and the concave portion 572 are alternately repeated, and are continuously formed along the outer circumferential portion 529 of the plate.

Accordingly, the contact area between the outer peripheral portion 529 and the inner peripheral portion 511c of the plate may be increased. Accordingly, a contact force between the shielding plate portion 520 and the cover portion 510 may be improved.

In addition, an increase in volume due to thermal expansion of the cover portion 510 and the shielding plate portion 520 may be compensated for by the concave portion 572.

As a result, as the cover part 510 and the shielding plate part 520 are separated from each other, the size of the space formed may be minimized. Accordingly, leakage or leakage that may occur through the space can be minimized.
