In addition, the guide rib 17 shown in FIGS. 1 and 2 protrudes from the connector housing body 13 in the same direction (arrow in FIG. X and the direction of the arrow X'). And the guide rib 17 is parallel to the restricting rib 16 and in the protruding direction (direction of arrow X and arrow X' in FIG. The arrow Y direction) extends linearly in the vertical direction (arrow Z direction in FIG. 2 ). Also, as shown in FIG. 2 , the guide rib 17 is formed to have the same width from the base end 17a to the distal end 17b in the protruding direction (directions of arrow X and arrow X' in FIG. 2 ).

When the limit rib 16 is inserted into the limit groove 26 (shown in FIG. 3 ) of the cover 21 from the end 16c, the guide rib 17 is inserted into the guide groove 27 of the cover 21 (shown in FIG. 3 ) from the end 17c (see FIG. 2 ). shown).

The restriction rib 16 and the guide rib 17 are formed such that respective cross-sectional configurations perpendicular to respective extending directions (directions of arrow Z in FIG. 2 ) are different from each other. That is, the cross-sectional configuration of the restriction rib 16 is substantially trapezoidal, and the cross-sectional configuration of the guide rib 17 is substantially rectangular.

Next, referring to FIG. 3 , the cover 21 constituting a part of the cover-fitted connector 3 according to the embodiment of the present invention will be described in detail. FIG. 3 is a plan view showing an unfolded state of the cover 21 according to the embodiment of the present invention.

As shown in FIG. 3, the cover 21 has a cover body 22 and a connected portion 23. The connected portion 23 is arranged in the cover body 22 and is connected to the connecting portion 14 when the cover 21 is fitted with the connector housing 11 (see FIG. 2 ) connections (see Figures 1 and 2).

The cover body 22 has a first cover body 22a and a second cover body 22b, and the first cover body 22a and the second cover body 22b are connected to each other by a hinge 24, thereby having the opened first cover body 22a and the second cover body 22b Such structures that can be folded and stacked.

A lead-out opening 25 in the shape of an elongated dome (box-like) is formed on the cover body 22 (the first cover body 22a and the second cover body 22b) for connecting the cover 21 with the connector housing 11 ( Refer to FIG. 2 ) lead out the electric wires (not shown) to the outside of the cover body 22 during mating.

Each of the connected parts 23 has a pair of left and right grooves 26 formed to correspond to the respective restricting ribs 16 (see FIG. 2 ) and to fit the cover 21 with the connector housing 11 (see FIG. 1 ). The hour restricting rib 16 is inserted into each of the pair of left and right grooves 26 from an end portion 16 c (see FIG. 2 ) in the extending direction of the restricting rib 16 (direction of arrow Z in FIG. 2 ).

In a state (for example, see FIG. 1 ) where the cover 21 is fitted with the connector housing 11 (see FIG. 2 ), the restriction rib 16 inserted from the end 16c (see FIG. 2 ) controls the fitting of the cover 21 with respect to the connector housing 11 and break away.

Moreover, each of the connected parts 23 has a pair of left and right grooves 27, and the guide rib 17 (see FIG. A portion 17 c (see FIG. 2 ) is inserted into each of the pair of left and right grooves 27 .

The guide rib 17 is inserted into the guide groove 27 from the end portion 17 c (see FIG. 2 ) in a state (for example, see FIG. 1 ) in which the cover 21 is fitted with the connector housing 11 (see FIG. 2 ).

When the connecting portion 14 of the connector housing 11 (see FIG. 2 ) is connected to the connected portion 23 of the cover 21, turning the cover 21 relative to the connector housing 11 can change the position of the lead-out opening 25 of the cover 22 relative to the connector. The direction of the housing 11, thereby enabling the electric wires (not shown) to be drawn out in directions different from each other.

Moreover, the notch part 32 is formed in the cover body 22 (the 1st cover body 22a and the 2nd cover body 22b). The end portion 31 of the cutout portion 32 is positioned at the boundary between the connector housing body 13 and the connection portion 14 (see FIG. 2 ) when the cover 21 is fitted with the connector housing 11 . Overlapping the first cover 22 a with the second cover 22 b allows the connecting portion 14 of the connector housing 11 to be covered by the cover 22 together with the connected portion 23 . Even in this state, the connector housing body 13 (see FIG. 1 ) is exposed to the outside of the cover 21 .

The cutout portion 32 is arranged on each of the first cover body 22a and the second cover body 22b so that even when the cover 21 is fitted with the connector housing 11 by inverting the cover 21 relative to the connector housing 11 by an angle of 180 degrees , the connector housing 11 (see FIG. 2 ) can also be connected to the cover 21 .

The cutout portion 32 has a configuration formed by cutting out a portion equal to the depth A in the insertion direction of the connector housing 11 (see FIG. 2 ). Fitting the cover 21 with the connector housing 11 as shown in FIG. 1 allows a portion equal to the depth A to cover the connection portion 14 of the connector housing 11 and be positioned to overlap the connection portion 14 . Therefore, when the cover 21 is mated with the connector housing 11, the length of the cover 21 is substantially equal to the length B shown in FIG. 3 .

That is, since the notch portion 32 has a configuration of cutting out a portion corresponding to the depth A as shown in FIG. is shorter, so the overall length C of the connector 1 fitted with the cover (see Fig. 1) becomes shorter due to the portion equal to the depth A.

Also, the cover body 22 (the first cover body 22 a and the second cover body 22 b ) has a concave portion 33 formed adjacent to the notch portion 32 .

The recess 33 is configured such that hooking a finger or the like with a step formed at the opening edge 34 of the recess 33 facilitates fitting the connector 1 of the cover (in which the cover 21 fits with the connector housing 11 (see FIG. 1 )) relative to An operation of connecting and disconnecting a mating connector or the like (not shown).

Next, referring to FIGS. 4 and 5 in addition to FIGS. 1 to 3 , the mating operation observed when the cover is mated with the connector housing constituting a part of the connector for assembling the cover according to the embodiment of the present invention will also be described. Describe the operational effects of the connectors fitted with the cover.

FIG. 4 is a side view showing the cover-fitted connector of FIG. 1 . FIG. 5 is a cross-sectional view showing a step portion including the recess of FIG. 4 .

As shown in FIGS. 1 to 5 , the cover 21 cooperates with the connector housing 11 , and a mating connector housing (not shown) is inserted into the connector housing 11 from the insertion port 15 (see FIG. 2 ) of the connector housing 11 .

Then, the terminals accommodated in the terminal accommodating cavity 12 (see FIG. The electric wires (not shown) of the terminals in the connector housing 11 are pulled out, so that the electric wires (not shown) are pulled out from the lead-out opening portion 25 (see FIG. 3 ) of the cover 21 .

In order to fit the cover 21 with the connector housing 11, the restricting rib 16 of the connecting portion 14 of the connector housing 11 is inserted from the end 16c (see FIG. 2) into the first end of the cover 21 in the open state (see FIG. 3). The cover 22a or the second cover 22b is in the restricting groove 26 of the connected part 23 . Then, when the second cover 22b or the first cover 22a is covered to overlap with the other, the remaining part of the restriction rib 16 is inserted into the restriction of the connected portion 23 of the second cover 22b or the first cover 22a. slot 26.

With the above operations, the cover 21 is fitted with the connector housing 11 . In this state, engagement of the restriction groove 26 with the restriction rib 16 inserted into the restriction groove 26 controls fitting and disengagement of the cover 21 relative to the connector housing 11 .

As mentioned above, when the cover 21 is mated with the connector housing 11, the cutout portion 32 of the cover body 22 covers the connection portion 14 of the connector housing body 13 (see FIG. 2 ), and the end portion 31 of the cutout portion 32 (see FIG. 3 ) is positioned at the boundary of 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, fitting of the cover 21 with the connector housing 11 shortens the length of the cover 21 by a portion equal to the depth A shown in FIG. 3 , enabling the cover 21 to have a length B shown in FIG. 3 . By doing this, as shown in FIG. 1 , the overall length C of the cover-fitted connector 1 is shortened by a portion equal to the depth A shown in FIG. 3 .

Moreover, since the cutout portion 32 (see FIG. 3 ) is formed at the cover body 22, it is not necessary for the cover 21 to cover the outer periphery of the connector housing 11, thus, as shown in FIG. The dimension of the width D becomes larger.

That is, among the portion of the connector housing 11 that interferes with the cover 21 caused by the fitting of the cover 21 with the connector housing 11 , the connection portion 14 of the connector housing 11 connected with the connected portion 23 of the cover body 22 is arranged at The inside of the cover 22. On the contrary, the connector housing body 13 is exposed to the outside through the cutout portion 32 of the cover body 22 . Therefore, substantially only the connection portion 14 of the connector housing 11 is covered by the cover body 22 when the cover 21 is fitted with the connector housing 11 .

Therefore, it is sufficient that the cover 21 has a size having a portion for covering electric wires led out from the connector housing 11 and a portion for arranging the connected portion 23 . Therefore, the portion of the cover 21 for covering the connector housing 11 can be suppressed to a minimum, thereby preventing expansion of the cover 21 as much as possible, thus suppressing expansion of the connector 1 fitted with the cover.

Also, as described above, even when the cover 21 is reversed at an angle of 180 degrees with respect to the connector housing 11 , the connecting portion 14 of the connector housing 11 can be connected to the connected portion 23 of the cover 21 . Therefore, the direction of the electric wire drawn out from the drawing opening portion 25 of the cover 21 can be changed to a different direction by inverting the cover 21 by 180 degrees to fit the cover 21 with the connector housing 11 .

Also, as shown in FIG. 5 , fitting of the cover 21 with the connector housing 11 allows the recess 33 of the cover 22 to be adjacent to the connector housing body 13 exposed to the outside from the cutout 32 (see FIG. 1 ) of the cover 22 .

Therefore, using the step formed at the opening edge 34 (see FIG. 3 ) of the recess 33 to catch fingers or the like can facilitate the fitting of the connector 1 of the cover (wherein the cover 21 is fitted with the connector housing 11 ) relative to the mating connector. and other connection and disconnection operations.

As described above, the restricting rib 16 of the connector housing 11 protrudes from the connector housing 11 in a direction perpendicular to the pull-out direction (direction of arrow Y in FIG. 2 ) for pulling the cover 21 away from the connector housing 11 ( Arrow X and arrow X' directions in FIG. 2 ), and the restriction rib 16 is formed from the base end 16a toward the distal end 16b in the protrusion direction (arrow X and arrow X' directions in FIG. 2 ). become larger in width. Also, a restriction groove 26 is formed on the cover 21 to correspond in configuration to the restriction rib 16 (see FIGS. 2 and 3 ).

Therefore, when a torsional force including a pulling force in a direction pulling the cover 21 away from the connector housing 11 (the direction of the arrow Y in FIG. 2 ) is applied to the cover 21 , it is possible to prevent the base end 16 a from being thin and distant. The thick wedge-shaped cross-section delimiting rib 16 at the end 16 b emerges from a delimiting groove 26 (see FIGS. 2 and 3 ) having a corresponding cross-sectional configuration. Therefore, it is possible to improve the cap holding force against twisting force.

Also, when the restricting rib 16 of the connecting portion 14 is inserted into the restricting groove 26, the guiding rib 17 of the connecting portion 14 is simultaneously inserted from the end portion 17c (see FIG. In the guide groove 27 of the connected part 23 of the cover body 22a or the second cover body 22b. Then, when the second cover 22b or the first cover 22a is covered to overlap the other, the remaining part of the guide rib 17 is inserted into the connected portion 23 of the second cover 22b or the first cover 22a. In the guide groove 27.

Here, each of the guide rib 17 and the guide groove 27 has a cross-sectional configuration different from that of the respective restriction rib 16 and restriction groove 26 . That is, the cross-sectional configuration of the restriction rib 16 is substantially trapezoidal and the cross-sectional configuration of the guide rib 17 is substantially rectangular.

Therefore, erroneous insertion of the restricting rib 16 into the guide groove 27 cannot be done due to the difference in the cross-sectional configurations from each other. Therefore, fitting of the cover 21 in a wrong position can be prevented.

The cover-fitted connector 1 according to the embodiment of the present invention includes: a connector housing 11 accommodating terminals connected to terminals of electric wires; and a cover 21 configured to fit with the connector housing 11 and to Cover the wires pulled out from the connector housing 11.

On the contrary, the connector housing body 13 is exposed to the outside through the cutout portion 32 of the cover body 22 . Therefore, substantially only the connecting portion 14 of the connector housing 11 is covered by the cover body 22 when the cover 21 is fitted with the connector housing 11 . Therefore, it is sufficient that the cover 21 has a size having a portion for covering electric wires led out from the connector housing 11 and a portion for providing the connected portion 23 . Therefore, the portion of the connector housing 11 covered by the cover 21 can be suppressed to a minimum, thereby preventing expansion of the cover 21 as much as possible, thus suppressing expansion of the connector 1 fitted with the cover.

Also, according to the embodiment of the present invention, even when the cover 21 is reversed relative to the connector housing 11 , the connecting portion 14 of the connector housing 11 can be connected with the connected portion 23 of the cover 21 . Therefore, by inverting the cover so that the cover 21 fits with the connector housing 11 , the direction of the electric wire drawn out from the lead-out opening portion 25 of the cover 21 can be changed to a different direction.

Also, according to an embodiment of the present invention, when the cover 21 is fitted with the connector housing 11 , the recess 33 of the cover 22 is adjacent to the portion of the connector housing body 13 exposed outside from the cutout 32 of the cover 22 . Therefore, using the steps formed in the opening edge 34 (see FIGS. 1 and 3 ) of the recess 33 to hook fingers or the like can facilitate the mating of the connector 1 (where the cover 21 is fitted with the connector housing 11 ) with the cover assembled. Connection and disconnection operations of connectors, etc.

Moreover, according to an embodiment of the present invention, the restricting rib 16 of the connector housing 11 is perpendicular to the first direction (arrow Y direction in FIG. 2 ) for pulling the cover 21 away from the connector housing 11 from the connector housing 11. protrudes in the second direction (direction of arrow X and arrow X' in FIG. 2 ), and the restricting rib 16 is formed to extend from the base end 16a in the second direction (direction of arrow X and arrow X' in FIG. 2 ). It becomes larger in width in the first direction toward the distal end 16b. Also, the restriction groove 26 of the cover 21 is formed to correspond to the restriction rib 16 in its configuration. Therefore, when a torsional force including a pulling force in a direction (arrow Y direction in FIG. 2 ) for pulling the cover 21 away from the connector housing 11 is applied to the cover 21, the restriction rib 16 can be prevented from coming off from the restriction groove 26. . Therefore, it is possible to improve the cap holding force against twisting force.

Also, according to an embodiment of the present invention, the connector housing 11 has a guide rib 17 extending in parallel with the restricting rib 16 in the third direction of the restricting rib 16 and protruding from the connector housing 11 in the second direction. . The cover 21 has a guide groove 27 into which the guide rib 17 having a cross-sectional configuration different from that of the restriction rib 16 is inserted. Therefore, the insertion of the restriction rib 16 into the guide groove 27 cannot be completed due to the difference in cross section from each other. Therefore, fitting of the cover 21 to a wrong position can be prevented.

Although the cover-fitted connector of the present invention has been described above based on the embodiment shown in the drawings, the present invention is not limited thereto, and the structure of each part can be replaced with any structure having a similar function.

For example, according to an embodiment of the present invention, the specification describes the situation that the restriction rib 16 is provided on the connector housing 11 and the restriction groove 26 is provided on the cover 21; however, it is also possible to provide the restriction rib 16 on the cover 21 and restrict The slot 26 is provided on the connector housing 11 .

Also, for example, according to an embodiment of the present invention, the description describes the case where the guide rib 17 is provided on the connector housing 11 and the guide groove 27 is provided on the cover 21; however, it is also possible to provide the guide rib 17 on the cover 21 and The guide groove 27 is provided on the connector housing 11 .
