Description

  The present invention relates to a shield connector for equipment and a wire harness. In particular, after high-voltage, high-current, and waterproof environments, by electrically processing an insulated wire that electrically connects a device with multiple device-side terminals installed inside the shield case and the insulated wire. The present invention relates to a shield connector for equipment and a wire harness that are shielded.

  Since a motor used in a hybrid electric vehicle (HEV) is a three-phase AC drive, three wire harnesses that electrically connect the inverter and the motor are required. Further, the battery for driving the motor has a high voltage, and two wire harnesses are required in addition to the low voltage 12V system. Accordingly, two or three electric wires for power transmission and reception used in the hybrid system in the HEV vehicle are routed.

  In addition, the power transmission / reception among the inverter, battery, and motor is large, and the AC frequency is high, so the wire harness may become a noise source, and the wire harness for HEV vehicles needs to ensure a shielding function. It becomes.

  Therefore, a connector having a shield function for connecting the device side and the electric wire has been proposed. In patent document 1, the electric wire side terminal for connecting with the terminal of an insulated wire with an apparatus side terminal, and the inner shell fixed to the terminal part of the shield member which surrounds the electric wire 2 or 3 collectively, A shield connector for equipment having a shield shell made of an external shell has been proposed. Here, the inner shell has an inner cylinder part, and the outer shell has an outer cylinder part, and the terminal part of the shield member is sandwiched between the outer cylinder part and the inner cylinder part press-fitted into the outer cylinder part. As a result, the shield shell is fixed.

Conventionally, the wire side terminals are connected to the equipment side with bolts, but the efficiency of the installation work with tools and the extra design of the equipment (for example, the terminal installation work window formed in the equipment case) In order to improve the efficiency of the work by omitting etc.), a fitting-type connector that can connect the electric wire side terminal in the connector and the device only by fitting the connector to the device has also been proposed. This connector employs a structure in which two or three pole terminals are accommodated in one connector housing so that two or three pole terminals can be connected simultaneously.

  However, in the case of the connector as described above, it is necessary to simultaneously fit two-pole or three-pole terminals and to simultaneously remove the fitted two-pole or three-pole terminals. For this reason, there has been a problem that the insertion force of the terminal is larger than that of one pole at the time of mounting. In addition, when the wire harness is detached from the device in maintenance or the like, there is also a problem that the working force is deteriorated because the connector detachment force becomes larger than that in the case of one pole.

In addition, connectors that simultaneously fit two-pole or three-pole terminals have to be designed with connector housings for two-pole or three-pole, respectively.
The present invention has been made to solve the above-described problems. By fitting each pole, the work efficiency during installation and maintenance is improved and post-processing is performed on the insulated wire.
