Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a diagram showing an electric compressor 1 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view showing the vicinity of the connector terminal 11. In fig. 1, the pressing member 30 is not shown for simplicity.
The motor-driven compressor 1 includes: an electric motor 2; an inverter 3, the inverter 3 being a driving circuit for driving the electric motor 2; and a compression mechanism 4, wherein the compression mechanism 4 is driven by the electric motor 2 to compress the refrigerant. The motor-driven compressor 1 is applied to, for example, an air conditioner for a vehicle, and is incorporated in a refrigerant circulation path through which a refrigerant circulates, together with a condenser, a pressure reducer (an expansion valve, etc.), and an evaporator, to constitute a refrigeration cycle. In the present embodiment, the refrigerating machine oil (lubricating oil) circulates in the refrigerant circulation path together with the refrigerant.
In the electric compressor 1, the movable scroll 4a is rotated by the main shaft 5 driven to rotate by the electric motor 2 to compress the refrigerant in the compression mechanism 4 composed of the movable scroll 4a and the fixed scroll 4 b. A current is inputted to the electric motor 2 through a wire 7, and the rotor 8 is rotated with respect to the stator 9 by a magnetic field generated by the inputted current, thereby driving the spindle 5 to rotate.
The lead wire 7 is pulled out from (the coil portion of) the stator 9 of the electric motor 2, and most of it is covered to expose the tip portion. In the present embodiment, the connector terminal 11 is provided at the tip end portion (the exposed portion described above) of the wire bundle 70 composed of a plurality of (for example, four) wires 7.
The connector terminal 11 is accommodated in the connector housing 12. The connector housing 12 is made of, for example, resin. The connector housing 12 has an opening 13 for communicating the inside and outside thereof. The wire harness 70 passes through the opening 13.
The connector terminal 11 is electrically connected to a pin 15 of an airtight plate 14 provided in a current output portion of the inverter 3. Here, the pin 15 corresponds to the "conductive member" of the present invention.
The connector housing 12 is formed to be attachable to an annular insulator 16, the insulator 16 is disposed around the vicinity of the airtight plate 14 of the lead 15, and a sealing member 17 made of rubber is interposed between the connector housing 12 and the lead 15 as an electrical insulator for sealing the attachment portion (see fig. 10A and 10B described later).
The sealing member 20 is interposed between the inner wall of the opening 13 of the connector housing 12 and the wire harness 70. The seal member 20 performs a function of sealing a gap between the inner wall of the opening 13 of the connector housing 12 and the wire harness 70 (sealing function).
The motor-driven compressor 1 has a pressing member 30 that presses the sealing member 20 toward the wire harness 70 side (the wire 7 side). The pressing member 30 includes a pair of holding members (a first holding member 31 and a second holding member 32).
In the present embodiment, the connector housing 12 has a so-called bundle housing shape, and includes a plurality of (three in the present embodiment) housing portions for housing the plurality of (three in the present embodiment) connector terminals 11.
Next, the sealing member 20 and the pressing member 30 (the first clamping member 31 and the second clamping member 32) according to the present embodiment will be described in detail with reference to fig. 3 to 8.
Fig. 3 is a perspective view of the assembled connector housing 12, sealing member 20, and pressing member 30. Fig. 4 is an exploded perspective view of the connector housing 12, the sealing member 20, and the pressing member 30.
Fig. 5 is a perspective view of the connector housing 12. Fig. 6 is a perspective view of the first clamping member 31. Fig. 7 is a perspective view of the second holding member 32. Fig. 8 is a perspective view of the sealing member 20.
The sealing member 20 is formed of a rubber material having electrical insulation (insulating rubber material). The seal member 20 has a main body portion 21, a first cylindrical portion 22, and a second cylindrical portion 23. The main body 21 is attached to the inner wall of the opening 13 of the connector housing 12, and has a through hole 24 through which the wire harness 70 (the wire 7) passes.
The first cylindrical portion 22 extends from the main body portion 21 to the outside of the connector housing 12. The inner space 22a of the first cylindrical portion 22 communicates with the through hole 24 of the main body portion 21. In addition, the wire harness 70 (the wire 7) passes through the inner space 22a of the first cylindrical portion 22.
The second cylindrical portion 23 extends from the main body portion 21 toward the inside of the connector housing 12. The inner space of the second cylindrical portion 23 communicates with the through hole 24 of the main body portion 21. In addition, the wire harness 70 (the wire 7) passes through the inner space of the second cylindrical portion 23.
The first and second holding members 31 and 32 constituting the pressing member 30 are made of, for example, resin, and each have a plate shape. In the present embodiment, the outer peripheral portion of the first cylindrical portion 22 of the sealing member 20 is sandwiched by the first sandwiching member 31 and the second sandwiching member 32 to press (in other words, fasten) the first cylindrical portion 22 of the sealing member 20 to the wire harness 70 side (the wire 7 side). In particular, in the present embodiment, as shown in fig. 2, the protrusions 31t, 32t are formed on the surface of the first clamping member 31 on the side facing the first cylindrical portion 22 and the surface of the second clamping member 32 on the side facing the first cylindrical portion 22, respectively, and the outer peripheral portion of the first cylindrical portion 22 is intensively clamped by the protrusions 31t, 32t to press (in other words, fasten) the first cylindrical portion 22 to the wire harness 70 side (the wire 7 side). The outer peripheral portion of the first cylindrical portion 22 is flattened by the protrusions 31t and 32 t.
In the present embodiment, a plurality of claw portions 33 are erected on the second clamp member 32. In a state in which the outer peripheral portion of the first cylindrical portion 22 of the sealing member 20 is sandwiched by the first sandwiching member 31 and the second sandwiching member 32, the pressing state (in other words, the fastening state) in which the first cylindrical portion 22 of the sealing member 20 is pressed toward the wire harness 70 side (the wire 7 side) is well maintained by hooking each claw portion 33 of the second sandwiching member 32 to the first sandwiching member 31. In the present embodiment, the claw portion 33 is provided to the second clamp member 32, but the claw portion 33 may be provided to the first clamp member 31, or the claw portion 33 may be provided to the first clamp member 31 instead of the second clamp member 32. In addition, a through hole 34 may be formed in a portion of the first clamping member 31 and the second clamping member 32 where the claw portion 33 is hooked, and the claw portion 33 may be inserted into the through hole 34 to be hooked.
The second holding member 32 has an extension 35 extending to the connector housing 12 side. The extension 35 abuts the outer surface of the connector housing 12. Further, the extension 35 is formed with a claw portion 33' and a through hole 36 functioning as an "engaging portion" of the present invention. A protrusion 37 provided on the outer surface of the connector housing 12 is fitted into the through hole 36. The claw portion 33' stands on the extension portion 35 and is hooked on a protruding portion 38 provided on the outer surface of the connector housing 12. Accordingly, the pressing member 30 has the claw portion 33' of the extension portion 35 and the through hole 36 as engaging portions with the connector housing 12.
Fig. 9A and 9B are diagrams showing a method of inserting the connector terminal 11 provided at the tip end of the harness 70 (the wire 7) into the connector housing 12. Here, fig. 9A is a plan view, and fig. 9B is a front view.
As shown in fig. 9A and 9B, a plurality of (three in the present embodiment) connector terminals 11 are inserted from a plurality of (three in the present embodiment) opening portions 13 of the connector housing 12. Subsequently, the installation of the pressing member 30 is performed.
Fig. 10A and 10B illustrate the mounting operation of the connector housing 12. Here, fig. 10A shows a sealing member mounting step of mounting the sealing member 17 to the airtight plate 14. Fig. 10B shows a connector housing mounting step of mounting the connector housing 12 on the airtight plate 14.
By the mounting operation of the connector housing 12 shown in fig. 10A and 10B, the mounting portion of the connector housing 12 is sealed with only the electrical insulator without a gap, and electrical insulation can be ensured.
However, strictly speaking, there may be a minute gap between the sealing member 20 and the wire harness 70 penetrating the sealing member 20. In addition, strictly speaking, there may be a minute gap between the plurality of wires 7 constituting the wire bundle 70. These clearances hardly function as inflow passages for allowing the refrigerant or lubricating oil introduced into the system of the motor-driven compressor 1 to flow into the connector housing 12. In the present embodiment, the first cylindrical portion 22 of the seal member 20 is pressed (in other words, fastened) toward the wire harness 70 (toward the wire 7) by the pressing member 30 so that the cross-sectional area of the inflow passage is reduced (in other words, the aforementioned gap is reduced), and thus inflow of the refrigerant or the lubricating oil into the connector housing 12 can be suppressed. As a result, leakage of electricity through lubricating oil or the like can be suppressed. In other words, the electrical insulation of the connector housing 12 is improved.
According to the present embodiment, the motor-driven compressor 1 includes: an electric motor 2; a drive circuit (inverter 3) that drives the electric motor 2; a compression mechanism 4, wherein the compression mechanism 4 is driven by the electric motor 2 to compress the refrigerant; a conductive member (pin 15) connected to the driving circuit (inverter 3); a wire 7, said wire 7 being pulled out from the electric motor 2; a connector terminal 11, the connector terminal 11 connecting the wire 7 with the conductive member (pin 15); a connector housing 12, wherein the connector housing 12 has an opening 13 through which the lead wire 7 passes, and accommodates the connector terminal 11; a sealing member 20, wherein the sealing member 20 is clamped between the inner wall of the opening 13 and the lead 7; and a pressing member 30, wherein the pressing member 30 presses the sealing member 20 toward the lead wire 7. Therefore, since the pressing member 30 can firmly hold the lead wire 7 via the sealing member 20, damage of the lead wire 7 at the installation site of the sealing member 20 can be suppressed. In other words, the vibration resistance of the wire 7 at the location where the seal member 20 is provided is improved.
Further, according to the present embodiment, the seal member 20 has: a main body 21, wherein the main body 21 has a through hole 24 for the lead 7 to pass through and is mounted on the inner wall of the opening 13; and a cylindrical portion (first cylindrical portion 22) extending from the main body portion 21 to the outside of the connector housing 12 so that the internal space 22a communicates with the through hole 24 of the main body portion 21, and the lead wire 7 passes through the internal space 22a. The pressing member 30 presses the cylindrical portion (first cylindrical portion 22) toward the wire 7. Therefore, the cylindrical portion (the first cylindrical portion 22) of the sealing member 20 can be collectively pressed toward the lead wire 7 side by the pressing member 30.
Further, according to the present embodiment, the pressing member 30 includes a pair of sandwiching members (first sandwiching member 31 and second sandwiching member 32) sandwiching the outer peripheral portion of the cylindrical portion (first cylindrical portion 22). Therefore, the cylindrical portion (the first cylindrical portion 22) of the sealing member 20 can be concentrated and pressed toward the lead wire 7 side by a simple structure.
Further, according to the present embodiment, the pressing member 30 has an engagement portion (the claw portion 33' of the extension portion 35 and the through hole 36) that engages with the connector housing 12. Thereby, displacement of the pressing member 30 with respect to the connector housing 12 can be suppressed.
In addition, the sealing member 20 is preferably formed of an insulating rubber material. It is preferable that the wire harness 70 composed of the plurality of wires 7 pass through the opening 13, and the seal member 20 is interposed between the inner wall of the opening 13 and the wire harness 70. Preferably, the connector housing 12 accommodates the plurality of connector terminals 11.
The electric compressor 1 may be a horizontal electric compressor in which the electric motor 2 and the compression mechanism 4 are arranged in series in the horizontal direction, or a vertical electric compressor in which the electric motor 2 and the compression mechanism 4 are arranged in series in the plumb direction.
