The screw <figref>44</figref> for fixing of the plug housing <figref>10</figref> and of the female housing <figref>40</figref> together is attached to the socket housing <figref>40</figref> attached.

As next will be described the operation of the present embodiment. The male terminal fittings, and the Subverbinder <figref>14</figref> are in the main body <figref>11</figref> of the plug housing <figref>10</figref> attached. About that addition, a cover <figref>34</figref> on a rear surface of the plug housing <figref>10</figref> secured or mounted. Next , as in <figref idrefs="S14">1</figref> shown, the connector housing <figref>10</figref> at the innermost surface side the panel or the panel <figref>1</figref> rotated so that the Positionsfixiervertiefung <figref>28</figref> of flange <figref>21</figref> on the left side (relative to the front view it is arranged). Furthermore, the connector housing is<figref>10</figref> bevelled or inclined so that the side of which with the projection <figref>31</figref> is provided to the Front projects (see <figref idrefs="S17">4</figref>), And the hood <figref>12</figref> of the plug housing <figref>10</figref> is in the mounting hole <figref>2</figref> in the in by the arrow <figref idrefs="S17">4</figref> shown Direction used.

Of the head Start <figref>31</figref> is first in the mounting hole <figref>2</figref> used. When the flange <figref>20</figref> against the innermost surface of the panel <figref>1</figref> beats (please refer <figref idrefs="S18">5</figref>), Reaches the fixed retaining claw <figref>22</figref> the hole edge the attachment hole <figref>2</figref>And the Positionsfixierstift <figref>3</figref> is or is in the Positionsfixiervertiefung <figref>28</figref> used, by the fact by the wider insertion <figref>29</figref> to be led. Next is the plug housing <figref>10</figref>. as indicated by arrow in <figref idrefs="S18">5</figref> is shown rotated by the fixed retaining claw <figref>22</figref> as an axis is used, so that the side of the plug housing <figref>10</figref>. which with the Positionsfixiervertiefung <figref>28</figref> is provided, the plate <figref>1</figref> approaches. The fixed retaining claw <figref>22</figref> becomes on the outermost surface side the attachment hole <figref>2</figref> pressed and the claw members <figref>24</figref> beat against the hole edge of this mounting hole <figref>2</figref>, This being the movable retaining claws <figref>23</figref> inward flexing. Furthermore is the Positionsfixierstift <figref>3</figref> in the Positionsfixiervertiefung <figref>28</figref> in such a distance used, that this Positionsfixierstift <figref>3</figref> to the back it protrudes.

There continues the rotation, proposes the side of the plug housing <figref>10</figref>. which with the Positionsfixiervertiefung <figref>28</figref> the flange <figref>20</figref> is provided, against the innermost surface the panel <figref>1</figref> (please refer <figref idrefs="S19">6</figref> and <figref idrefs="S20">7</figref>). Then accesses the fixed retaining claw <figref>22</figref> in the hole edge of the attachment hole <figref>2</figref> at the outermost area thereof, and the jaw member <figref>24</figref> pass through the outermost surface side the panel <figref>1</figref>Wherein said movable retaining claws <figref>23</figref> away to their original Shape back, and the jaw member <figref>24</figref> engage with the hole edge of the attachment hole <figref>2</figref> at the outermost surface side thereof. Furthermore there is the Positionsfixierstift<figref>3</figref> in a state whereby this in the Positionsfixiervertiefung <figref>28</figref> to was used at a distance such that this rear by a area it protrudes.

That the male connector M is fitted and fixed in a state whereby the hole edge of the attachment hole <figref>2</figref> in between the flange <figref>20</figref> on one side and the fixed retaining claw <figref>22</figref> and the jaw members <figref>24</figref> the movable retaining claws <figref>23</figref> on the other side is taken, thus the plug connector to prevent M thereto, either in the direction forward or away backward to become. About that addition of Positionsfixierstift is <figref>3</figref> by Positionsfixiervertiefung <figref>28</figref> of flange <figref>20</figref> passed, thereby turning the to prevent the male connector M. The male connector M is thus to the plate <figref>1</figref> mounted in a waiting state or mounted, and its rotation is prevented.

If the corresponding female connector F with the male connector M be paired to, the female housing <figref>40</figref> to the inner surface the projection <figref>31</figref> placed, so that the rib <figref>32</figref> in the guide groove <figref>42</figref> fit becomes. In this state, the female connector F is being in the Hood <figref>12</figref> pressed. After all , as in <figref idrefs="S21">8</figref> is shown attached to the socket housing <figref>40</figref> fortified screw <figref>44</figref> into the screw hole <figref>18</figref> of the fastening member <figref>17</figref> of plug housing <figref>10</figref> screwed, this being the male and M and female connector F in a fitted state fastened together. A peripheral edge of the rubber stopper <figref>41</figref> engages resiliently in the outermost surface of the panel <figref>1</figref> a, creating a seal provided becomes.

In the present embodiment, enters the of the panel <figref>1</figref> projecting Positionsfixierstift <figref>3</figref> by the Positionsfixiervertiefung <figref>28</figref> in the flange &lt;?page 5?&gt;<figref>20</figref> of plug housing <figref>10</figref> therethrough, wherein the plug housing <figref>10</figref> at a rotation within the attachment hole <figref>2</figref> prevents. If the head Start <figref>31</figref> not provided, the connector housing may <figref>10</figref> at the innermost side of the mounting hole <figref>2</figref> pan or rotate, said Positionsfixierstift <figref>3</figref> as an axis is used, even though the Positionsfixierstift <figref>3</figref> by the Positionsfixieröffnung <figref>28</figref> was passed. As a result of this would be an insertion of the hood <figref>12</figref> through the mounting hole <figref>2</figref> time consuming.

the present embodiment solves this problem by the projection <figref>31</figref> provided or made available is that of a portion of the front end of the hood <figref>12</figref> projects. If the Positionsfixierstift <figref>3</figref> by Positionsfixiervertiefung <figref>28</figref> was passed, or is the projection <figref>31</figref> first into the mounting hole <figref>2</figref> fitted what it hood <figref>12</figref> allowed to be passed smoothly. Specifically opens itself or opens the Positionsfixiervertiefung <figref>28</figref> in the peripheral edge of the flange <figref>20</figref>And the projection and the collection <figref>31</figref> is arranged on the side which of these Positionsfixiervertiefung <figref>28</figref> opposite, the hood <figref>12</figref> is arranged between the two. Accordingly, the male housing <figref>10</figref> in the following order attached or fastened: the plug housing <figref>10</figref> becomes first tilted in its axial direction and the projection <figref>31</figref> becomes at the hole edge of the attachment hole <figref>2</figref> attached, the plug housing <figref>10</figref> becomes then returned in a straight position, wherein the projection <figref>31</figref> as the pivot or rotational axis is used, and the Positionsfixierstift <figref>3</figref> is the Positionsfixiervertiefung <figref>28</figref> passed. That is, the plug housing <figref>10</figref> can easily and effectively through the mounting hole <figref>2</figref> passed and thereby fixed or be set. Moreover, met the head Start <figref>31</figref> a guiding function, if the corresponding or matching socket housing <figref>40</figref> in the hood <figref>12</figref> fitted becomes. Thus simplifies the projection<figref>31</figref> the fitting operation the female and male housing <figref>40</figref> and <figref>10</figref>,
