As shown in FIG. 3A, the pair of sliding projection walls 13 enter the pair of sliding grooves 5 of the housing 1. The front mask 10 is provided with a plurality of projecting walls 14 on its upper part. As shown in FIGS. 1 and 2, each protruding wall 14 is inserted into each insertion portion 6 of the housing 1. On the rear surface of the front mask 10, a pair of locking claws 15 are provided inside the pair of sliding projection walls 13. As shown in FIG. 3B, the pair of locking claws 15 are locked in the locking grooves 7 of the housing.

The retainer 20 is inserted into the retainer opening 8 from below the housing 1. The retainer 20 includes a terminal locking portion (not shown) that locks the terminals 30 housed in each terminal housing chamber 2 and a connector connector that locks the data communication connector 40 housed in the inner connector housing chamber 3. And a stop portion 21. The retainer 20 is provided so as to be movable between the temporary locking position (solid line position in FIG. 8) and the main locking position (phantom line position in FIG. 8) of the housing 1. At the temporary locking position of the retainer, insertion of the terminal 30 and the data communication connector 40 into the housing 1 is allowed. When the retainer 20 is in the main locking position, the retainer 20 is in a position where a terminal locking portion (not shown) is locked to the terminal 30 housed in the housing 1 and the data communication housed in the housing 1. It is located at a position where the connector locking portion 21 is locked to the connector 40 for use.

As shown in FIG. 7, each terminal 30 is in the form of a female terminal and is connected to the end of the electric wire W1. Each terminal 30 is inserted into the terminal accommodating chamber 2 through an opening on the rear surface of each terminal accommodating chamber 2. When each terminal 30 is accommodated in the terminal accommodating chamber 2 of the housing 1, the lance 8a of the housing 1 and the terminal engaging portion (not shown) of the retainer 20 doubly engage each other to prevent the terminal 30 from moving in the terminal removing direction. It has been blocked.

The data communication connector 40 is a female connector and incorporates a pair of female terminals. The data communication connector 40 is connected to the end of the data communication wire W2. The data communication wire W2 is composed of a twin pair wire. An electromagnetic shield member X is interposed between the data communication connector 40 and the data communication wire W2.

The data communication connector 40 is provided with a locking claw 41 (shown in FIGS. 2 and 8) that projects downward from the bottom surface. The data communication connector 40 is provided with a pair of locking recesses 42 (shown in FIGS. 3C and 7) at the left and right side ends.

The data communication connector 40 is inserted into the inner connector housing chamber 3 through an opening on the rear surface of the inner connector housing chamber 3. Unlike the terminal 30, the data communication connector 40 is housed over the inner connector housing chamber 3 of the housing 1 and the connector insertion hole 12 of the front mask 10. That is, the insertion tip of the data communication connector 40 is arranged in the connector insertion hole 12 of the front mask 10. The tip end surface of the data communication connector 40 is arranged so as to face the front end of the connector insertion hole 12 of the front mask 10.

A plurality of lap ribs 4 projecting from the inner peripheral surface of the inner connector housing chamber 3 of the housing 1 are in contact with the outer peripheral surface of the data communication connector 40. As a result, the data communication connector 40 is prevented from rattling in the inner connector housing chamber 3 and is positioned at the center position in the inner connector housing chamber 3.

As shown in FIG. 2, the data communication connector 40 is accommodated in the inner connector accommodating chamber 3, and the engaging claw 41 is engaged with the connector lance 9 of the housing 1, as shown in FIG. As described above, the locking recess 42 is locked to the connector locking portion 21 of the retainer 20 so that the retainer 20 is doubly locked and is prevented from moving in the connector detaching direction.

Next, the procedure for assembling the connector A will be described. As shown in FIG. 5, the front mask 10 is attached to the front surface of the housing 1. Specifically, the pair of sliding projection walls 13 of the front mask 10 are inserted into the pair of sliding grooves 5 of the housing 1 from below the housing 1, and the front mask 10 is slid upward. Then, the protruding walls 14 of the front mask 10 are inserted into the insertion portions 6 of the housing 1, and the pair of locking claws 15 of the front mask 10 are locked in the pair of locking grooves 7 of the housing 1 (FIG. 3). (See (a) and (b)). In the assembling stage shown in FIG. 6, the front mask 10 is prevented from falling down by only the locking force of the locking claws 15.

Next, as shown in FIG. 7, each terminal 30 is inserted into the housing 1 in which the retainer 20 is set at the temporary locking position (the solid line position in FIG. 8) from the opening on the rear surface of the terminal accommodating chamber 2 of the housing 1. To do. The terminal 30 inserted into the terminal accommodating chamber 2 is locked to the lance 8a of the housing 1 and is prevented from moving in the removal direction. Further, as shown in FIGS. 7 and 8, the data communication connector 40 is inserted through the opening on the rear surface of the inner connector housing chamber 3 of the housing 1. The data communication connector 40 is inserted until its tip completely enters the connector insertion hole 12 of the front mask 10. The data communication connector 40 inserted into the inner connector accommodating chamber 3 is locked to the connector lance 9 of the housing 1 and is prevented from moving in the detaching direction.

Finally, the retainer 20 is moved from the temporary locking position (solid line position in FIG. 8) to the main locking position (phantom line position in FIG. 8). As a result, each terminal locking portion (not shown) of the retainer 20 is locked to the terminal 30, and the connector locking portion 21 is locked to the data communication connector 40 (see FIG. 2). That's it!

As described above, the connector A is mounted on the front surface of the housing 1 and the housing 1 having the terminal housing chamber 2 and the inner connector housing chamber 3 which are opened on the front surface, and introduces the terminal at a position corresponding to the terminal housing chamber 2. A front mask 10 having a port 11 and a connector insertion hole 12 at a position corresponding to the inner connector housing chamber 3, a terminal 30 housed in each terminal housing chamber 2, and an inner connector housing of the housing 1. The chamber 3 and the data communication connector 40 housed over the connector insertion hole 12 of the front mask 10 are provided.

Therefore, since the data communication connector 40 is inserted (fitted) into the connector insertion hole 12 of the front mask 10, in other words, the data communication connector 40 functions as a bar of the front mask 10, and thus the front mask 10 Even if an external force that moves downward is applied to the data communication connector 40, the data communication connector 40 moves downward and does not come off from the housing 1.

Further, when the retainer 20 is temporarily locked and the terminal 30 is pulled out, an external force that moves downward may be applied to the front mask 10. However, since the data communication connector 40 receives this external force. The data communication connector 40 moves downward and does not come off from the housing 1.

Further, as shown in the comparative example shown in FIG. 9, the data communication connector 40 is inserted only into the inner connector housing chamber 3 of the housing 1, and the front mask 10 is tapered at a position corresponding to the inner connector housing chamber 3. If the connector introduction hole 50 is provided, the terminal 51 of the mating connector will be the inner connector when the center axis position of the connector introduction hole 50 of the front mask 10 and the data communication connector 40 of the inner connector housing chamber 3 are deviated. There is a possibility that the container may not be guided to the proper insertion position in the accommodation chamber 3. However, in this embodiment, since the data communication connector 40 is inserted into the connector insertion hole 12 of the front mask 10, the above-mentioned inconvenience does not occur.

The connector A is attached to the terminal accommodating chamber 2 and the inner connector accommodating chamber 3 of the housing 1 and includes a retainer 20 that prevents the terminals 30 and the data communication connector 40 from moving in the disconnecting direction. Therefore, the retainer 20 locks the terminal 30 and the data communication connector 40, and it is possible to prevent both the terminal 30 and the data communication connector 40 from coming off.

The housing 1 is provided with a plurality of lap ribs 4 protruding from the inner connector housing chamber 3. When the data communication connector 40 is inserted into the inner connector accommodating chamber 3, the plurality of wrap ribs 4 abut (press) against the outer peripheral surface of the data communication connector 40, so that the data communication connector 40 becomes a inner connector accommodating chamber. Since it is positioned at the central position within 3, the tip end surface of the data communication connector 40 is smoothly inserted into the connector insertion hole 12 without hitting the edge of the connector insertion hole 12 of the front mask 10 or the like. The plurality of wrap ribs 4 prevent the data communication connector 40 from rattling in the inner connector housing chamber 3 when the data communication connector 40 is housed in the inner connector housing chamber 3.

The inner connector housing chamber 3 and the connector insertion hole 12 are arranged at the center positions of the housing 1 and the front mask 10 in the width direction. Therefore, since the data communication connector 40 is fitted in the center position of the front mask 10 in the width direction, the force corresponding to the external force is greater than that in the case where the front mask 10 is fitted in one position in the width direction. Is excellent in That is, when the front mask 10 is fitted in one side position in the width direction, when an external force acts on the other side position, a large rotational moment acts on the front mask 10 and the front mask 10 is moved to the housing 1. Although there is a high possibility that problems such as displacement and falling may occur, when the front mask is fitted at the center position in the width direction, the front mask 10 is affected by an external force applied to any one of the left and right positions. Since a large rotational moment does not act on the front mask 10, it is unlikely that the front mask 10 will be displaced from the housing 1 or fall out.

The connector A includes a data communication connector 40 that is an inner connector housed in the housing 1. Therefore, it is possible to fit the mating connector (not shown) as the connector A without separately handling the data communication connector 40, which facilitates the work.

In the above-described embodiment, the front mask 10 is mounted on the front surface of the housing 1 by moving from the lower side to the upper side along the front surface of the housing 1, but the moving direction in which the front mask 10 is mounted is (for example, the lateral direction). However, the present invention can be applied.
