Next, an example of the assembly work of the connector C of the present embodiment will be described.
First, the sub-housing 40 is assembled to the housing body 30 (see FIG. 10). At this time, the moving plate 50 is disposed at the forward movement position. The sub housing 40 is inserted into the housing accommodating chamber 34 of the housing body 30 from the rear. Here, when the sub housing 40 is inclined obliquely with respect to the front-rear direction, the projecting piece 44 of the sub housing 40 abuts against the wall-shaped portion 35 of the housing body 30. Thereby, it is prevented that the tab part 11 contact | abuts to the housing main body 30, and the situation where the tab part 11 contacts the housing main body 30 and deform | transforms, such as a bending, can be avoided.

  When the sub-housing 40 is in the normal insertion posture, each rib 42 of the sub-housing 40 fits into the receiving groove 36 of the housing accommodating chamber 34, and the protruding piece 44 of the sub-housing 40 fits into the fitting hole 54 of the moving plate 50. The sub housing 40 is smoothly inserted into the housing accommodating chamber 34. In the insertion process, the rib 42 slides in the receiving groove 36 and the projecting piece 44 slides on the peripheral surface of the fitting hole 54 to guide the insertion operation of the sub housing 40.

  As shown in FIG. 11, when the sub-housing 40 is inserted into a proper position, the front end of the rib 42 abuts against the stop wall 37 and further advancement is restricted, and the stopper 38 and the protrusion 43 And the backward movement of the sub-housing 40 is restricted. Thereby, the sub-housing 40 is held in a state assembled in the housing accommodating chamber 34. At this time, the front surface of the sub-housing 40 is aligned with the front surface of the terminal holding portion 31 in substantially the same position in the front-rear direction. The tip of the tab portion 11 passes through the insertion hole 51 of the moving plate 50 and is disposed in front of the wall portion 52. The projecting piece 44 passes through the fitting hole 54 of the wall portion 52, and the front end of the projecting piece 44 is positioned in front of the wall portion 52. The protruding piece 44 is disposed so as to overlap the inside of the peripheral wall portion 53.

When the sub housing 40 is in the wrong insertion posture (upside down posture), each rib 42 of the sub housing 40 does not fit into the receiving groove 36 of the housing housing chamber 34, and the protrusion 44 of the sub housing 40 does not fit. The sub-housing 40 cannot be inserted because it does not fit into the fitting hole 54 of the moving plate 50. Accordingly, it is detected that the sub-housing 40 is in an incorrect posture, and the sub-housing 40 is inserted into the housing accommodating chamber 34 again after the insertion posture is corrected.
Thus, the assembly work of the connector C is completed.

Next, an example of a fitting operation between the connector C of the present embodiment and the mating connector 60 will be described.
Before fitting with the mating connector 60, as shown in FIG. 11, the lever 70 is set to the initial position and the moving plate 50 is set to the forward position.

  First, the mating connector 60 is fitted into the hood portion 20, and the cam pin 61 is engaged with the cam portion 55 of the moving plate 50 and the cam groove 73 of the lever 70. The sub housing 62 of the mating connector 60 is fitted inside the peripheral wall 53 of the moving plate 50. That is, the peripheral wall portion 53 of the moving plate 50 is inserted into a fitting space 64 formed between the housing main body 63 and the sub housing 40 of the mating connector 60. Here, a force in a direction intersecting with the fitting direction of the connectors C and 60 acts on the peripheral wall portion 53 of the moving plate 50, so that the protruding piece 44 of the sub-housing 40 is inside the peripheral wall portion 53 of the moving plate 50. Therefore, it is possible to prevent the peripheral wall portion 53 from being deformed or inclined at an angle. Thereby, the sub housing 62 of the mating connector 60 is smoothly fitted into the peripheral wall portion 53 of the moving plate 50.

  Next, the lever 70 is rotated from the initial position to the fitting completion position. Then, the moving plate 50 and the mating connector 60 are integrated and pulled into the back side of the hood portion 20, and both the connectors C and 60 are brought into a normal fitting state. The moving plate 50 moves to the rear side along the fitting groove 57 along the protruding piece 44. The moving plate 50 reaches the retracted position, and the front surface of the mating connector 60 contacts or approaches the front surface of the wall portion 52 of the moving plate 50, and the front surface of the sub-housing 40 contacts or approaches the rear surface of the wall portion 52.

  Thus, the fitting operation of both connectors C is completed. When the two connectors C and 60 in the fitted state are detached, the lever 70 is rotated in the return direction from the fitting completed position to the initial position. Then, the connectors C and 60 are pulled apart through an operation reverse to that at the time of fitting.

Next, operations and effects of the embodiment configured as described above will be described.
The connector C of the present embodiment includes a housing body 30 having a hood portion 20 that opens to the front, a sub-housing 40 in which the tab portion 11 projects forward from the front surface and is assembled to the housing body 30 from the rear, and the hood portion 20 And a moving plate 50 having a wall portion 52 formed with an insertion hole 51 through which the tab portion 11 is inserted. The front surface of the sub-housing 40 has a region 45 where the tab portion 11 protrudes. A projecting piece 44 that protrudes forward is provided around, and the front end of the projecting piece 44 is located in front of the wall portion 52 of the wall portion 52 in a state where the sub-housing 40 is assembled to the housing body 30. According to this configuration, when the sub-housing 40 is assembled to the housing body 30, the tabs 11 can be prevented from coming into contact with the housing body 30 by the protruding pieces 44, so that the tabs 11 can be protected.

  Further, the moving plate 50 has a peripheral wall portion 53 protruding forward from the peripheral edge of the wall portion 52, and the housing main body 30 is fitted so that the mating connector 60 can be fitted between the hood portion 20 and the peripheral wall portion 53. The projecting piece 44 is disposed so as to overlap the inner side of the peripheral wall portion 53. According to this configuration, when the mating connector 60 is slidably contacted with the inner surface and the outer surface of the peripheral wall portion 53 of the moving plate 50 when the mating connector 60 is fitted, the projecting piece 44 overlaps the inner side of the peripheral wall portion 53. Therefore, the deformation of the peripheral wall portion 53 can be prevented.

  Further, the projecting piece 44 is provided in a part around the region 45 and is arranged inside the peripheral wall portion 53. According to this configuration, the connector C can be made more compact than the one in which the protruding piece 44 is disposed outside the peripheral wall portion 53.

  Further, four projecting pieces 44 are provided around the region 45, and are arranged at four corners surrounding the region 45. According to this configuration, since the tab portion 11 is surrounded on all sides by the four projecting pieces 44, the tab portion 11 can be protected even if the entire circumference of the tab portion 11 is not continuously surrounded by the projecting pieces 44.

  Further, the projecting piece 44 is fitted when the sub housing 40 is correctly assembled to the housing body 30, and the fitting hole 54 where the projecting piece 44 is not fitted when the sub housing 40 is not correctly assembled to the housing body 30. Is formed on the wall 52. According to this configuration, since the erroneous assembly of the sub-housing 40 is detected, the sub-housing 40 can be reliably assembled correctly.

  Further, the projecting piece 44 has a plate shape and is provided with a thick portion 46 having a partially large thickness dimension. According to this configuration, since the protruding piece 44 is reinforced, the tab portion 11 can be reliably protected.
