JP 2006-22911 A (paragraphs 0032 to 0038, FIGS. 4 and 5)

  However, in the connector cover of Patent Document 1, when receiving an impact from the outside, both cover portions are fitted to the boss hole portions of the cover portions of the connector body, but are not engaged with each other. When the mounting convex part is removed from the boss hole part, there is a problem that each cover part is detached from the connector main body and the connector main body is not protected.

  The present invention has been made in view of such a point, and an object of the present invention is to reliably protect the connector when an impact load is applied.

  In order to achieve the above object, the present invention comprises a cover body in which a housing recess for housing a connector is formed, and a lid that closes the opening of the housing recess, and this lid intersects the direction in which the connector comes out. It is attached to the cover main body by sliding in the direction of the movement.

  Specifically, the present invention covers a periphery of a connector having a first connection portion to which the first tubular member is connected and a second connection portion to which the second tubular member is connected, and connecting both tubular members. The following solutions were taken for the connector cover that protects the connector.

  That is, the first invention includes a cover body in which a housing recess for housing the connector is formed, and a lid that closes at least a part of the opening of the housing recess, and the cover body includes the housing recess. A pair of side wall portions facing each other is formed, the lid body is slid in a facing direction of the pair of side wall portions, and the pair of side wall portions are bridged and attached to the pair of side wall portions. It is characterized by.

  According to the first invention, the cover body slides in the opposite direction of the pair of side wall portions, that is, the direction intersecting the both side wall portions, bridges the pair of side wall portions, and The opening is blocked. In other words, the lid is attached to both side walls by sliding and moving across the opening. Therefore, when an impact load acts on the connector cover, the impact load acts on the connector from the connector cover, and the connector moves toward the opening of the housing recess and collides with the lid. Then, the impact load acts in a direction crossing the sliding direction of the lid. Therefore, the lid body does not slide in the sliding direction due to the impact load. Therefore, the lid body does not come off from both side wall portions. As a result, the connector does not come off from the connector cover. For this reason, the connector can be reliably protected when an impact load is applied.

  According to a second invention, in the first invention, at least one of the pair of side wall portions is formed with a fitting portion into which an end portion in the sliding direction of the lid body is fitted, and the lid body is arranged in the facing direction. The pair of side wall portions are bridged by sliding and being fitted into the fitting portions.

  According to 2nd invention, the insertion part is formed in at least one of both side wall parts, and the slide direction edge part of the cover body is inserted in this insertion part. Therefore, when an impact load is applied to the connector cover, the connector moves to the opening side of the housing recess, and even if the connector collides with the lid, the end of the lid in the sliding direction comes into contact with the outer periphery of the fitting portion. The lid can be reliably prevented from coming off from the side wall.

  According to a third invention, in the second invention, the fitting portion is configured by through holes formed in the pair of side wall portions, and the lid body passes through the through holes and the pair of side walls. The pair of side wall portions are bridged by penetrating the portions.

  According to the third invention, when an impact load is applied to the connector cover, the connector moves to the opening side of the housing recess, and when the connector collides with the lid body, the through-holes are formed at two positions on both ends in the sliding direction of the lid body. Abuts around the outside. Therefore, it can prevent more reliably that a cover body remove | deviates from a both-sides wall part.

  According to the third invention, when the lid is attached to the cover body, the lid is inserted into the through-hole of the side wall from the outside of the one side wall, and is slid in the opposite direction of the both side walls as it is. Then, the front end portion is inserted into the through hole of the other side wall portion, and the lid body is bridged to both side wall portions. Thus, the lid body can be easily attached to the cover body because the lid body is simply slid to insert both through holes.

  In a fourth aspect based on the third aspect, the lid includes a contact portion that contacts the outer peripheral edge of the through hole on the outer peripheral surface of the one side wall portion, and the inner peripheral surface of the one side wall portion. And an engaging portion that engages with the outer peripheral edge of the through hole.

  According to the fourth aspect of the invention, the abutting portion comes into contact with the outer periphery of the through hole on the outer peripheral surface of the one side wall portion, so that the lid body can be restricted from sliding to the other side wall portion side. Moreover, since the latching | locking part latches to the outer periphery of the through-hole in the internal peripheral surface of one side wall part, it can control that a cover body slides outside the one side wall part. Therefore, it is possible to restrict the lid body from sliding in the opposite direction of the side wall portions, and more reliably prevent the lid body from coming off the cover body.

  According to a fifth invention, in the third or fourth invention, a pressing portion for pressing the connector toward the bottom surface of the housing recess is formed on the surface of the lid on the side of the housing recess. And

  According to the fifth invention, since the pressing portion presses the connector toward the bottom surface of the housing recess, no gap is formed between the connector and the lid, and the connector moves toward the lid. Can be regulated. Therefore, there is no room for the connector to move when an impact load is applied, the connector does not collide with force toward the lid, and the lid can be prevented from being damaged.

  In a sixth aspect based on the second aspect, the fitting portion is formed by a through-hole formed in one of the pair of side wall portions, and the outer peripheral surface of the other of the pair of side wall portions has an outer side. An overhang is formed, and a fitting groove into which the overhang is fitted is formed in the lid corresponding portion of the lid, and the lid is slid from the side of the other side wall. One end portion penetrates the through hole, and the flange portion is fitted into the fitting groove, thereby bridging the pair of side wall portions.

  According to the sixth aspect of the invention, when an impact load is applied to the connector cover, when the connector moves to the opening side of the housing recess and the connector collides with the lid, the portion penetrating the through hole of the lid penetrates. While contacting the outer periphery of a hole, the inner peripheral surface of a fitting groove contacts the collar part of a cover main body. Therefore, it can prevent more reliably that a cover body remove | deviates from a both-sides wall part.

  Further, according to the sixth invention, the lid body is slid and moved through the through-holes at the front end sides of the both side wall portions, and the flange portion is fitted into the fitting groove, and the lid body is bridged on the both side wall portions. Let Thus, since the lid is simply slid in the opposing direction of the side wall portions, the lid can be easily attached to the cover body.

  As mentioned above, according to this invention, a connector can be reliably protected at the time of an impact load effect | action.

  The tube side accommodating portion 29 has a U-shaped cross section and opens upward. The tube side accommodating part 29 has a bottom wall part 29a having an arcuate cross section and a pair of side wall parts 29b and 29b that rise upward from the upper end of the bottom wall part 29a and face each other. The width between the pair of side wall portions 29b and 29b is a constant width from the rear end to the front side in the front-rear direction center along the shape of the tube 5 in which the tube connecting portion 19 is press-fitted and swollen. In this front-rear center front portion, the width becomes narrower toward the front side, and the front end portion has a constant width. Each of the side walls 29b has a rectangular shape that is long in the front-rear direction when viewed from the left-right direction, and a through-hole 31 (fitting portion) through which the lid body 25 passes is formed at the center in the vertical direction.

  The through-hole 31 has a U-shape that opens downward when viewed from the left-right direction, and has a through-hole body 31a that extends linearly in the front-rear direction, and a through-hole that extends slightly downward from both front and rear ends of the through-hole body 31a. It is comprised by the edge parts 31b and 31b. A groove 33 extending in the left-right direction is formed near the front center in the front-rear direction of the upper outer periphery of the through-hole body 31a.

  Ribs 35 are formed on the outer peripheral surface of each side wall 29b so as to surround the upper side and both front and rear sides of the through hole 31. As shown in FIG. 7, the rib 35 extends upward from the rear outer peripheral edge of the through hole 31, extends forward from the rear upper corner of the through hole 31, and reaches the front end of the side wall 29b. It bends downward and extends to the lower end of the side wall 29b. The groove 33 is located on the front end in the front-rear direction at the lower end of the portion extending in the front-rear direction of the rib 35. The rib 35 is formed with an L-shaped cutout groove 35a for the purpose of preventing sink marks.

  The pipe side accommodating portion 27 has a back wall portion 27a that connects the rear ends of both side wall portions 29b, 29b of the tube side accommodating portion 29, and a bottom wall portion 27b that covers the lower side of the back wall portion 27a. doing. The back wall portion 27a has a U-shape when viewed from above and below. On the other hand, the bottom wall portion 27b extends rearward from the rear end of the bottom wall portion 29a of the tube side accommodating portion 29, and the rear end portion gradually inclines upward to connect to the lower end of the back wall portion 27a. Yes.

  FIGS. 8A and 8B are perspective views showing the lid body 25, where FIG. 8A is a view seen from the front upper side, and FIG. 8B is a view seen from the lower front side. 9A and 9B are diagrams showing the lid body 25, where FIG. 9A is a plan view and FIG. 9B is a bottom view.

  The lid body 25 is made of a substantially square resin plate, the rear half portion is substantially rectangular, the lateral width gradually decreases from the front end toward the front, and the front end portion extends with a constant lateral width. . A thin plate portion 25a extending in the left-right direction, which is thinner than other portions, is formed on the rear side of the lid 25 in the center in the front-rear direction. The thin plate portion 25 a extends horizontally from the left end of the lid 25 to the right, and the right end is located on the left side of the right end of the lid 25. A rectangular slit 25b is formed on the left side of the thin plate portion 25a. A rectangular plate-like locking claw 37 (locking portion) is formed at the left end of the thin plate portion 25a so as to incline upward toward the left side. Since the clearance claw 37 is formed between the front and rear end faces of the slit 25b, the locking claw 37 can be bent up and down.

  Further, on the front side of the thin plate portion 25a on the upper surface of the lid body 25, a ridge portion 39 extending linearly in the left-right direction is formed. The protrusion 39 is fitted in grooves 33 and 33 formed in the side walls 29b and 29b of the cover main body 23 to prevent the lid 25 from being displaced in the front-rear direction.

  On the other hand, on the front and rear sides of the left end of the slit 25b on the lower surface of the lid 25, contact pieces 41, 41 that contact the outer peripheral edge of one of the pair of side wall portions 29b, 29b on the left side face downward. Projecting.

  In addition, pressing pieces 43 and 43 (pressing portions) that press the tube connecting portion 19 accommodated in the cover main body 23 toward the bottom wall portion 29a protrude from the front and rear ends of the lower surface of the lid 25. ing. Each pressing piece 43 has a base end piece 43a extending downward from the right end of the lower surface of the lid 25 and an inclined piece 43b inclined downward from the tip of the base end piece 43a to the right. The inclined piece 43b can be bent in the vertical direction.

  When attaching the cover body 25 to the cover body 23, the cover body 25 is inserted from the left side of the cover body 23 into the through hole 31 of the left side wall portion 29b and slides to the right. The right end portion is inserted into the through hole 31 of the right side wall portion 29b, and the contact pieces 41 and 41 are in contact with the outer peripheral edge of the through hole 31 of the left side wall portion 29b.

  In the middle of this sliding movement, the lid body 25 passes through the through-hole body 31 a of each through-hole 31, and each pressing piece 43 passes through the through-hole end portion 31 b of each through-hole 31. At the same time, the protrusion 39 passes through the groove 33 formed on the upper outer periphery of the through-hole body 31a. Further, when the locking claw 37 passes through the left through-hole 31, it comes into contact with the upper outer peripheral edge of the through-hole body 31a and bends downward, and returns when it passes through the through-hole body 31a.

  In this state, the abutment pieces 41, 41 abut against the left side wall portion 29 b, thereby restricting the lid 25 from sliding to the right, and the locking claw 37 is disposed at the left side wall. The lid body 25 is restricted from sliding to the left by engaging with the inner peripheral surface of the portion 29b. Thereby, it can prevent that the said cover body 25 slips out from both the said through-holes 31 and 31. FIG.

  Thus, the lid body 25 has left and right ends passing through the through holes 31 and 31 formed in the side walls 29b and 29b of the cover body 23, thereby connecting the side walls 29b and 29b to the bridge. The part corresponding to the said tube side accommodating part 27 among the opening of the said accommodation recessed part 21 is plugged up.

  Next, when the connector cover 1 is attached to the connector 7, first, the connector 7 to which the tube 5 is connected is fitted into the accommodating recess 21 of the cover body 23 from the opening side. At this time, the pipe connection portion 17 is fitted so that the base end portion is accommodated in the bottom wall portion 27 b of the pipe side accommodation portion 27 and the tube connection portion 19 is accommodated in the bottom wall portion 29 a of the tube side accommodation portion 29. .

  Next, the lid body 25 is slid rightward from the outside of the left side wall portion 29b, inserted into the through hole 31 of the left side wall portion 29b, and then inserted into the through hole 31 of the right side wall portion 29b. . In this state, the left and right end portions of the lid body 25 bridge both side wall portions 29b and 29b, and the portion corresponding to the tube side accommodation portion 29 in the opening of the accommodation recess 21 is closed. Then, the pressing piece 43 provided on the lower surface of the lid body 25 presses the tube connecting portion 19 toward the bottom wall portion 29a, so that a gap is formed between the tube connecting portion 19 and the bottom wall portion 29a and the lid body 25. Not formed.

  When the connector cover 1 is attached to the connector 7 in this manner and the impact load in the vertical direction mainly acts on the cover body 1, the connector 7 tends to move to the opening side of the housing recess 21. At that time, first, since the tube connecting portion 19 of the connector 7 is pressed against the bottom wall portion 29a by the pressing pieces 43, 43 of the lid 25, there is no gap between the lid 25 and the tube connecting portion 19, and the connector 7 is difficult to move to the opening side of the housing recess 21, that is, the lid body 25 side. Therefore, the connector 7 does not give a large impact to the lid body 25. Further, the impact load from the outside is relatively large, the tube connecting portion 19 of the connector 7 moves toward the lid 25 against the pressing force of the pressing pieces 43, 43, and the impact load acts on the lid 25. In addition, the direction in which the lid 25 is removed from the through holes 31, 31 is orthogonal to the moving direction of the connector 7, and the left and right ends of the lid 25 abut against the outer peripheral edges of the through holes 31, 31 in the side wall portions 29b, 29b. Therefore, the lid body 25 does not come off from the cover body 23.

  On the other hand, when an impact load in the left-right direction mainly acts on the cover body 23, the impact load mainly acts on the rib 35. Further, as described above, since the lid body 25 cannot be removed from the through holes 31 and 31 of the side wall portions 29b and 29b by the contact pieces 41 and 41 and the locking piece 37 of the lid body 25, the lid body 25 is covered with the cover body 23. I will not deviate

  As described above, even when an impact load is applied from the outside, the lid 25 is not detached from the cover body 23, so that the connector 7 is reliably protected.

-Effect of Embodiment 1 of the Invention-
According to the above embodiment, the lid body 25 is slid in the opposing direction of the pair of side wall portions 29b, 29b, that is, the direction orthogonal to the both side wall portions 29b, 29b, that is, the left-right direction, 29b is bridged to close the opening of the housing recess 21 in which the connector 7 is housed. That is, the lid body 25 is detached from the side wall portions 29b and 29b by sliding and moving across the opening of the housing recess 21. Therefore, when an impact load acts on the connector cover 1, the impact load acts on the connector 7 from the connector cover 1, and the connector 7 moves toward the opening of the housing recess 21 and collides with the lid 25. Then, the impact load acts on the lid 25 in a direction orthogonal to the sliding direction. Therefore, the lid body 25 is not slid by this impact load. Therefore, the lid body 25 is attached to the side wall portions 29b and 29b. As a result, the connector 7 is not detached from the connector cover 1. Therefore, the connector 7 can be reliably protected when an impact load is applied.

  Moreover, according to the said embodiment, the through-holes 31 and 31 are formed in the both-sides wall parts 29b and 29b, and the both right-and-left both ends of the cover body 25 have penetrated these through-holes 31 and 31. Accordingly, when an impact load is applied to the connector cover 1, the connector 7 moves to the opening side of the housing recess 21, and when the connector 7 collides with the lid body 25, the left and right ends of the lid body 25 are aligned with the outer periphery of the through hole 31. It is possible to reliably prevent the lid 25 from coming off from the side walls 29b and 29b.

  Furthermore, according to the embodiment, when the impact load is applied to the connector cover 1, the connector 7 moves to the opening side of the housing recess 21, and when the connector 7 collides with the lid body 25, both left and right end portions of the lid body 25. It contacts the outer periphery of the through holes 31, 31 at two places. Therefore, it can prevent more reliably that the cover body 25 remove | deviates from both side wall part 29b, 29b.

  Further, according to the above embodiment, when the lid body 25 is attached to the cover main body 23, the lid body 25 is inserted from the outside of the left side wall portion 29b into the through hole 31 of the left side wall portion 29b and is directly moved to the right. And the right end portion is inserted into the through hole 31 of the right side wall portion 29b to bridge the lid body 25 on both side wall portions 29 and 29. Thus, since the lid body 25 is simply inserted, the lid body 25 can be easily attached to the cover body 23.

  Moreover, according to the said embodiment, since the contact pieces 41 and 41 contact | abut to the outer periphery of the through-hole 31 in the outer peripheral surface of the left side wall part 29b, the cover body 25 slides and moves to the right side wall part 29b side. Can be regulated. Further, since the locking claw 37 is locked to the outer peripheral edge of the through-hole 31 on the inner peripheral surface of the left side wall portion 29b, it is possible to restrict the lid 25 from sliding to the outside of the left side wall portion 29b. . Therefore, it is possible to restrict the sliding of the lid 25 in the opposing direction of the side wall portions 29b and 29b, and to prevent the lid 25 from coming out of the through holes 31 and 31.

  Moreover, according to the said embodiment, since the press pieces 43 and 43 are pressing the connector 7 toward the bottom wall part 29a, a clearance gap is not formed between the connector 7 and the cover body 25, but the connector 7 is used. Movement toward the lid 25 can be restricted. Since there is no room for the connector 7 to move when the impact load is applied and the connector 7 is unlikely to collide with the lid 25, damage to the lid 25 and the like can be suppressed.
