In this device, an electronic circuit body is placed on a base member made of a plate-like metal material placed on an assembly jig, the electronic circuit body is covered with a cover, and the electronic circuit body and the cover are bolted to the base member. It is set as the structure fixed by fastening. A plurality of terminals protrude outward from the electronic circuit body.

JP 2012-57769 A

  By the way, the base member mentioned above is made into various forms according to the attachment site | part of the vehicle which attaches a control circuit apparatus. For this reason, the assembly operation of the control circuit device described above is performed at the installation site of the control circuit device using a base member corresponding to the vehicle. That is, it is necessary to assemble the electronic circuit body, the cover, and the base member at the installation site of the control circuit device, and there is a problem that the work process at the installation site increases.

  In addition, since the electronic circuit body before assembly to be carried to the installation site is not covered with the cover, the terminals of the electronic circuit body are exposed during transportation. For this reason, there is a possibility that a problem such as deformation caused by contact of a foreign substance with the terminal during conveyance may occur.

  Furthermore, although the control circuit device of the above-described form may be used by being disposed in oil, conductive foreign matters such as metal wear powder are mixed in the oil. For this reason, there is a possibility that these foreign substances enter between a plurality of terminals of the electronic circuit body or between the terminals and the metal base member to cause a short circuit.

  It is an object of the present invention to provide a control circuit device for an automatic transmission for a vehicle that can be transported in a state in which a terminal is protected or can be attached to a member to be attached at a time and that is less likely to cause a short circuit. It is. It is another object of the present invention to provide a vehicle connector that is unlikely to cause a short circuit.

  The technology disclosed in this specification includes a main body portion in which a control circuit for an automatic transmission for a vehicle is incorporated, and a plurality of tab-shaped terminals extending from the main body portion in a row in a row direction. An upper case having a control circuit unit, a first terminal covering portion that covers the plurality of terminals from one side of the crossing direction that intersects the arrangement direction, and a cover that covers the plurality of terminals from the other side of the crossing direction.

In such an assembled state, the plurality of terminals of the control circuit unit are covered with the first terminal covering portion of the upper case and the second terminal covering portion of the lower case, so that foreign objects come into contact with the terminal during transportation. The occurrence of defects such as deformation can be suppressed.

  Moreover, at the installation site of the control circuit device, it is only necessary to attach the control circuit unit, the upper case, and the lower case, which have already been assembled in this manner, to the mounted member in a lump. The number of parts is reduced, and the work process can be reduced.

  Further, in a state where the control circuit device is attached to the metal attached member, an insulating lower case (second terminal covering portion) is disposed between the plurality of terminals and the attached member. A short circuit with the member to be attached can be prevented. Furthermore, since the partition is arranged between the plurality of terminals, a short circuit between the terminals can be suppressed.

  The control circuit device for the vehicle automatic transmission may have the following configuration.

  A unit side groove for fitting the edge of the partition into the main body may be provided. According to such a configuration, when the control circuit unit, the upper case, and the lower case are assembled, the edge of the partition wall is fitted in the unit side groove, so that the adjacent terminals The creepage distance between them becomes longer. That is, it is difficult for a short circuit between adjacent terminals to occur.

  The control circuit unit has a unit side mounting portion for mounting on the mounted member, and the upper case has a case side mounting portion for mounting on the mounted member. The unit side mounting portion and the case side mounting portion are It is good also as a structure fastened by a fastening member with respect to a to-be-attached member in the state piled up mutually.

  According to the above configuration, the upper case and the control circuit unit are collectively fastened to the attached member by the fastening member, so that the lower case locked to the upper case is also attached to the attached member. It will be attached. At the same time, the upper case, the lower case, and the control circuit unit are fixed to each other. That is, since the upper case or the lower case and the control circuit unit can be fixed to each other and the attachment means to the attached member of the control circuit device, the overall configuration can be simplified and the work can be performed. The process can also be reduced.

  In addition, since the case-side mounting part is provided on the upper case side different from the complex-shaped lower case in which the partition wall is formed, the configuration of each case is simplified compared to the configuration in which both are provided in one case. Can be easily formed.

  Further, the technology disclosed in this specification is a vehicle connector that is fitted to the control circuit device of the vehicle automatic transmission described above, and the edge of the partition wall is fitted in the state fitted to the control circuit device. A connector side groove is provided.

  According to such a configuration, the creepage distance between adjacent terminals is increased also on the vehicle connector side, so that a short circuit between the terminals is less likely to occur.

  According to the technology disclosed in this specification, there is provided a control circuit device for an automatic transmission for a vehicle that can be transported in a state where the terminal is protected, or can be attached to a member to be attached at a time, and a short circuit is unlikely to occur. can get. Further, a vehicle connector that is unlikely to cause a short circuit is obtained.
