It inserts into the regulation groove 26 of the to-be-connected part 23 of the cover main body 22b from the edge part 16c (refer FIG. 2). Thereafter, when the second cover main body 22b or the first cover main body 22a is covered and overlapped, the remaining portion of the restriction rib 16 is inserted into the restriction groove 26 of the connected portion 23.

  As a result, the cover 21 is fitted to the connector housing 11. In this state, the engagement of the cover 21 with the connector housing 11 is restricted by the engagement of the restriction groove 26 and the restriction rib 16 inserted therein.

  As described above, the notch 32 of the cover body 22 covers the connecting portion 14 (see FIG. 2) of the connector housing body 13 when the cover 21 is fitted to the connector housing 11, and the end of the notch 32. The portion 31 (see FIG. 3) is located at the boundary between the connector housing body 13 and the connecting portion 14 so that the connector housing body 13 is exposed to the outside of the cover 21.

  Therefore, when the cover 21 is fitted to the connector housing 11, the length of the cover 21 is shortened by the depth A shown in FIG. 3, and the length of the cover 21 is the length B shown in FIG. Thereby, as shown in FIG. 1, the full length C of the connector 1 with a cover becomes short by the depth A shown in FIG.

  Further, since the cover body 22 is formed with a notch 32 (see FIG. 3), it is not necessary for the cover 21 to cover the outer periphery of the connector housing 11, and as shown in FIG. It can suppress that the magnitude | size of the width | variety D becomes large.

  That is, among the portions of the connector housing 11 that interfere with the cover 21 due to the fitting of the cover 21, the connecting portion 14 of the connector housing 11 connected to the connected portion 23 of the cover main body 22 is disposed inside the cover main body 22.

Accordingly, the cover main body 22 covers substantially only the connecting portion 14 of the connector housing 11 when fitted to the connector housing 11.

  For this reason, the cover 21 should just be a magnitude | size which has the part which covers the electric wire withdraw | derived from the connector housing 11, and the part which arrange | positions the to-be-connected part 23. FIG. Therefore, the portion where the cover 21 covers the connector housing 11 can be minimized to prevent the cover 21 from being enlarged as much as possible, and the increase in size as the connector 1 with cover can be suppressed.

  Further, as described above, even if the cover 21 is inverted 180 degrees with respect to the connector housing 11, the connecting portion 14 of the connector housing 11 and the connected portion 23 of the cover 21 can be connected. For this reason, the direction of the electric wire led out from the lead-out opening 25 of the cover 21 can be changed in a different direction by reversing and fitting the cover 21 to the connector housing 11 by 180 degrees.

  Further, as shown in FIG. 5, when the cover 21 is fitted into the connector housing 11, the portion of the cover main body 22 is exposed to the portion of the connector housing main body 13 exposed to the outside from the notch 32 (see FIG. 1) of the cover main body 22. A recess 33 is adjacent.

  Accordingly, the connecting / disconnecting operation of the connector with cover 1 with the cover 21 fitted to the connector housing 11 with respect to the mating connector or the like is performed by placing a finger on the step formed on the opening edge 34 (see FIG. 3) of the recess 33. It can be done easily.

  As described above, the restriction rib 16 of the connector housing 11 protrudes in a direction perpendicular to the direction in which the cover 21 is pulled away from the connector housing 11 (the arrow Y direction in FIG. 2), and the protruding direction (in FIG. 1). It is formed so that the width becomes wider from the base end 16a toward the front end 16b in the directions of arrows X and X ′. Further, a restriction groove 26 is formed in the cover 21 in a shape corresponding to the restriction rib 16 (see FIGS. 2 and 3).

The regulating ribs 16 that are included do not come off from the corresponding regulating grooves 26 having a cross-sectional shape (see FIGS. 2 and 3). Therefore, the cover holding force against the twisting force can be improved.

  When the restriction rib 16 of the connecting portion 14 is inserted into the restriction groove 26, at the same time, the guide cover 17 of the connecting portion 14 is unfolded (the state shown in FIG. 3) in the first cover body 22a or the second cover body 22a. It inserts into the guide groove 27 of the to-be-connected part 23 of the cover main body 22b from the edge part 17c (refer FIG. 2). Thereafter, when the second cover main body 22b or the first cover main body 22a is covered and overlapped, the remaining portion of the guide rib 17 is inserted into the guide groove 27 of the connected portion 23.

  Here, the guide rib 17 and the guide groove 27 have a different cross-sectional shape from the restriction rib 16 and the restriction groove 26 as described above. That is, the cross-sectional shape of the regulation rib 16 has a substantially trapezoidal shape, but the cross-sectional shape of the guide rib 17 has a substantially rectangular shape.

  For this reason, even if the restriction rib 16 is erroneously inserted into the guide groove 27, the restriction rib 16 cannot be inserted due to a difference in cross-sectional shape. For this reason, it can prevent that the cover 21 is fitted in the wrong position.

  In this way, the connector with cover 1 according to the embodiment of the present invention is pulled out of the connector housing 11 by being fitted to the connector housing 11 that accommodates the terminal connected to the terminal of the electric wire and the connector housing 11.

For this reason, the direction of the electric wire led out from the lead-out opening 25 of the cover 21 can be changed in a different direction by reversing and fitting the cover 21 to the connector housing 11 by 180 degrees.

  Furthermore, according to the cover-equipped connector 1 according to the embodiment of the present invention, when the cover 21 is fitted to the connector housing 11, the connector housing body 13 exposed to the outside from the notch 32 (see FIG. 1) of the cover body 22. The recess 33 of the cover main body 22 is adjacent to this portion. Accordingly, a finger is applied to the step formed on the opening edge 34 (see FIGS. 1 and 3) of the recess 33 for connecting and disconnecting the connector with cover 1 with the cover 21 fitted to the connector housing 11 to the mating connector or the like. Etc. can be easily performed.

  Further, according to the cover-equipped connector 1 according to the embodiment of the present invention, the regulating rib 16 of the connector housing 11 is perpendicular to the direction (the arrow Y direction in FIG. 1) that separates the cover 21 from the connector housing 11 ( Projecting from the connector housing 11 in the direction of arrow X and arrow X ′ in FIG. 2, the width increases from the base end 16 a to the tip end 16 b in the projecting direction (arrow X and arrow X ′ direction in FIG. 1). It is formed to be wide. In addition, a restriction groove 26 is formed in the cover 21 in a shape corresponding to the restriction rib 16. For this reason, when a torsional force including a tensile force in a direction in which the cover 21 is pulled away from the connector housing 11 (the direction of the arrow Y in FIG. 1) is applied, the restriction rib 16 does not come off the restriction groove 26. Therefore, the cover holding force against the twisting force can be improved.

  Furthermore, according to the cover-equipped connector 1 according to the embodiment of the present invention, the connector housing 11 extends in parallel with the extending direction of the regulating rib 16 and projects from the connector housing 11 in the projecting direction of the regulating rib 16. The cover 21 has a guide groove 27 into which the guide rib 17 having a cross-sectional shape different from that of the regulating rib 16 is inserted. For this reason, if the restriction rib 16 is to be inserted into the guide groove 27, the restriction rib 16 cannot be inserted due to the difference in cross-sectional shape. For this reason, it can prevent that the cover 21 is fitted in the wrong position.

  The cover-attached connector of the present invention has been described based on the illustrated embodiment, but the present invention is not limited to this, and the configuration of each part is replaced with an arbitrary configuration having the same function. Can do.

  For example, in the embodiment of the present invention, the case where the regulation rib 16 is provided in the connector housing 11 and the regulation groove 26 is provided in the cover 21 has been described. However, the regulation rib 16 is provided in the cover 21 and the regulation groove 26 is provided. 26 may be provided in the connector housing 11.

  For example, in the embodiment of the present invention, the guide rib 17 is provided in the connector housing 11 and the guide groove 27 is provided in the cover 21. However, the guide rib 17 is provided in the cover 21 and the guide groove 27 is provided. 27 may be provided in the connector housing 11.

  INDUSTRIAL APPLICATION This invention is very useful for the connector with a cover which fits the cover which covers the electric wire pulled out from the connector housing in the connector housing which accommodates the terminal connected to the electric wire.
