Definitions

  • the present invention relates to a motor-driven compressor that includes a phase wire bundle formed by binding phase wires extending from phase coils and a wire connecting portion.
  • the wire connecting portion serves as a neutral point, at which the phase wires of the phase wire bundle are connected together.
  • Japanese Laid-Open Utility Model Publication No. 5-38368 discloses a motor-driven compressor in which lead wires extending from the phase coils are separately connected to connecting terminals in a cluster block. Phase wires, which form a neutral point, are bound together to form a phase wire bundle, and the distal ends of the wires in the phase wire bundle are collectively coupled to a non-connecting terminal (wire connecting portion).
  • Japanese Laid-Open Utility Model Publication No. 5-38368 uses binding threads to tie down the neutral point to the coil ends so that the neural point does not sway.
  • refrigerant gas gaseous refrigerant
  • liquefied refrigerant liquid refrigerant
  • the wire connecting portion at the neutral point is immersed in the liquid refrigerant remaining in the housing, the wire connecting portion and the housing are conducted to each other via the liquid refrigerant. If the motor-driven compressor starts operating in this state, the current through the wire connecting portion is likely to leak to the housing via the liquid refrigerant.
  • Japanese Laid-Open Patent Publication No. 2005-278289 discloses a rotating electric machine in which a neutral point terminal is formed such that the distal ends of wires at the neutral points do not protrude from a metal sleeve, and the neutral point terminal is covered with an insulating cap. This prevents short circuit between the coils and the distal ends of the wires at the neutral point in the rotating electric machine.
  • the neutral point terminal (wire connecting portion), which is a neutral point, is covered with an insulating cap, liquid refrigerant may enter the insulating cap, and the neutral point terminal may be immersed in the liquid refrigerant. This results in insufficient insulation resistance between the neutral point terminal and the housing. Therefore, to prevent the neutral point terminal from being immersed in liquid refrigerant, the insulating cap may be elongated to ensure the insulation distance to the wire connecting portion.
  • the binding process is troublesome and thus lowers efficiency of assembly of a motor-driven compressor.
  • the insulating cap needs to be bound to the coil end. This further lowers the assembly efficiency.
  • One aspect of the present invention is a motor-driven compressor comprising: an electric motor having a stator; a compression mechanism that is driven by the electric motor to compress refrigerant; an outer shell for accommodating therein the electric motor and the compression mechanism; a cluster block located inside the outer shell; a phase wire bundle that is formed by binding a plurality of phase wires extending from a plurality of phase coils, which form the stator; and a wire connecting portion serving as a neutral point, at which the phase wires of the phase wire bundle are connected together, wherein the phase wire bundle and the wire connecting portion are coated with an insulating member, and the insulating member is secured to the cluster block by a securing means.

  • FIG. 2 is a cross-sectional view taken along line 2 - 2 of FIG. 1 ;

Since the phase wires 35 U, 35 V, 35 W extend from the coil end 241 , the lead wires 240 U, 240 V, 240 W are not moved to positions inward of the stator core 23 .
  • the insulating tube 37 Since the insulating tube 37 is fitted in and held by the receiving hole 38 , the insulating tube 37 is unlikely to be detached from the phase wire bundle 36 .
  • the first embodiment has the advantages described below.
  • phase wire bundle 36 is prevented from swaying. That is, the phase wire bundle 36 is prevented from being moved to a position inward of the stator core 23 without using a binding thread.

  • the insulating tube 37 is secured to the cluster block 32 simply by fitting the insulating tube 37 in the receiving hole 38 . Such fitting operation is easy, which improves the efficiency of assembly of the motor-driven compressor 10 . Since the inner surface 382 of the receiving hole 38 contacts the insulating tube 37 , the insulating tube 37 is not easily detached from the receiving hole 38 . In other words, the insulating tube 37 is reliably secured to the cluster block 32 .
  • the receiving hole 38 can be easily formed in the cluster block 32 , which is made of insulating plastic. Accordingly, the structure for securing the insulating tube 37 to the cluster block 32 is simplified.
  • the phase wire bundle 36 can be extended as much as possible so that the phase wire bundle 36 is reliably prevented from sagging.
  • the present invention in which the insulating tube 37 is secured to the cluster block 32 , is particularly suitable for the motor-driven compressor 10 , which has components arranged in series and improves the assembly efficiency.
  • phase wire bundle 36 and the wire connecting portion 361 are coated with the insulating tube 37 . Therefore, even if liquid refrigerant is pooled in the motor-driven compressor 10 , the wire connecting portion 361 is prevented from being immersed in the liquid refrigerant.
  • FIG. 4 A second embodiment will now be described with reference to FIG. 4 .
  • the same reference numerals are given to those components that are the same as the corresponding components of the first embodiment, and detailed explanations are omitted.
