Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a terminal block device for a shielded electric cable provided in traveling drive equipment such as an inverter and a motor mounted on an electric vehicle or the like.

  The in-wheel motor electric vehicle converts the operation angle of the accelerator by the driver into a torque command and transmits it to the inverter device. The inverter device converts the power from the battery into a three-phase alternating current based on the torque command, and controls each motor of the left and right drive wheels.

  In general, such an inverter device or motor for driving the electric vehicle has a high voltage and a high current as compared with an inverter or motor for auxiliary equipment, and many harmful electromagnetic noises are generated. Therefore, for the connection between the inverter device and the motor, a shielded electric cable is used for each of the three UVW phases.

  Since the rain water etc. may be directly applied to the inverter device and the motor, particularly the motor which is an in-wheel motor, the waterproofness of the inverter device and the connection portion between the motor and the electric cable is very important. If the waterproofness is lost, water intrudes into the inside of the inverter device and the motor, increasing the possibility of a short circuit, an electric shock and the like. In the case of the in-wheel system electric car, since the electric cable is wired from the vehicle body to the wheel, mechanical fixing strength of the electric cable to the inverter device and the motor is also required.

  Also, the battery and the inverter device are usually connected by two shielded electric cables. Similar to the electrical cable between the inverter device and the motor, this electrical cable also needs to have a waterproof connection structure.

  As described above, not only shielding performance and waterproof performance, but also a function of fixing the electric cable with high strength is required for connection between the traveling drive device and the electric cable. For that purpose, conventionally, for example, a waterproof shield connector shown in FIG. 15 has been used. Patent Document 1 also discloses a waterproof shield connector having a similar structure to this.

  The waterproof shield connector 100 of FIG. 15 is a cylindrical shape made of conductive metal, and a portion where the sheath of the electric cable 3 is removed to expose the shield is inserted and the electric cable 3 is fixed. Thereby, the waterproof shield connector 100 and the electric cable 3 are electrically connected to each other, and the waterproofness is maintained. Further, one end of the waterproof shield connector 100 is inserted into the through hole 102 opened in the casing 101 of the travel drive device. The waterproof O-ring 103 is fitted between one end of the waterproof shield connector 100 and the inner periphery of the through hole 102. The waterproof shield connector 100 has a flange 104 at an outer peripheral portion, and is fixed to the housing 101 by inserting a fixing tool 106 such as a screw through a fixing hole 105 formed in the flange 101. A terminal 34 is attached to the end of the electric cable 3 by crimping.

  The structure which fixes an output harness to the output terminal block of a rotary electric machine is shown by FIG. 21, FIG. 22 of patent document 2 using a shield wire | line holding member and another member, without using a connector. The portion in contact with the output harness of the shield wire holding member is made of a conductive material. The other members are made of an electrically conductive material as a whole. Thus, the fixing of the output harness and the grounding are simultaneously performed.

  The conventional waterproof shield connector shown in FIG. 15 is expensive because it has a slightly complicated structure because it has a waterproof function and a fixing function at the same place, and is made of metal in order to have a shielding property. . Also, if the waterproof shield connector is made of metal, if there is a gap in the joint surface with the terminal block case, which is also made of metal, salt water etc. will intrude into this gap and rust will occur and the waterproofness will be impaired. There is a possibility that

  Further, the structures shown in FIGS. 21 and 22 of Patent Document 2 are unclear in detail as to the waterproofness between the output harness and the output terminal block and the mechanical fixing strength of the output harness to the output terminal block.

Thereby, the cost reduction of the terminal block apparatus for electric cables with a shield can be aimed at.

The waterproof functional member may be a waterproof rubber that closes a gap between the inner peripheral surface of the through hole and the outer peripheral surface of the electric cable.
The waterproof functional member made of waterproof rubber has a drawback that the fixing function of the electric cable is weak, but it is cheaper than the waterproof functional member made of grommet.
