<Embodiment>
An embodiment of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 1, the connector mounting structure in this embodiment includes a clamp (an example of the “mounting member” of the present invention) 10 that is fixedly mounted in a mounting hole H that is provided through the panel P of the vehicle body. The connector 30 is detachably attached to the clamp 10. In the following description, the front-rear direction refers to the fitting direction of the connector 30 and the fitting surface side (the right side in FIG. 1) of the connector 30 is the front side.

  The connector 30 has a housing 31 made of synthetic resin. As shown in FIG. 3, the housing 31 is provided with a hood portion 32 that opens forward. A terminal holding portion 33 that holds a tab terminal (not shown) is provided behind the hood portion 32. Is provided. A plurality of cavities 34 having a shape penetrating in the front-rear direction are formed inside the terminal holding portion 33, and a barrel portion (not shown) of a tab terminal and the barrel portion are crimped to the cavity 34. An electric wire (not shown) is accommodated. This electric wire is drawn out behind the housing 31.

  As shown in FIG. 2, a plurality of cavities 34 are provided side by side in two steps in the up-down direction and in the left-right direction. The bottom wall of the cavity 34 is provided with a lance 35 that cantilever and extends forward. The lance 35 is locked to a tab terminal accommodated in the cavity 34 from the rear side, thereby holding the tab terminal rearward in a state of being prevented from coming off.

  Further, as shown in FIG. 3, a retainer mounting hole 36 for mounting a side retainer (not shown) that is assembled across the plurality of cavities 34 is provided inside the terminal holding portion 33. The retainer mounting hole 36 opens on the lower surface of the terminal holding portion 33. On the other hand, the side retainer has a lattice shape, and openings are provided at positions corresponding to the plurality of cavities 34. For this reason, the tab terminal can be inserted into the cavity 34 from the rear of the terminal holding portion 33 in a state where the side retainer is held at the temporary locking position with respect to the retainer mounting hole 36. Furthermore, when the side retainer in the temporary locking position is pushed in to the final locking position, the lattice portion constituting each opening of the side retainer is locked to the tab terminal, so that the tab terminal is held in a state of being prevented from coming out backward. It is like that. As a result, the tab terminal is double-locked by the lance 35 and the side retainer and double-stopped.

  A cassette portion 37 to which the insertion piece 12 provided on the clamp 10 is inserted and fixed is provided at the lower portion of the housing 31. The cassette portion 37 has an insertion port that opens rearward, and a locking projection 38 that is elastically displaceable is provided inside the cassette portion 37. The locking projection 38 is disposed on the insertion path of the insertion piece 12, and when the insertion piece 12 is inserted from the insertion port of the cassette portion 37, the insertion piece 12 and the locking projection 38 interfere with each other. The locking projection 38 is elastically displaced from the inside of the cassette portion 37 toward the outside.

  The clamp 10 is made of synthetic resin, and as shown in FIG. 4, a clip 11 that is attached and fixed to the panel P by being inserted into the attachment hole H, and an insertion piece 12 disposed above the clip 11. And a loop portion 20 arranged in a loop shape and arranged behind the clip 11 are integrally provided.

  The clip 11 has a base portion 13, and a support column 14 extends downward from the base portion 13. As shown in FIG. 3, the column 14 is positioned below the mounting hole H, while the base end side positioned above the mounting hole H has a columnar shape when inserted into the mounting hole H as shown in FIG. 3. The tip side is slightly tapered. In addition, the base end side dimension of the support column 14 is formed slightly smaller than the hole diameter of the mounting hole H.

  As shown in FIG. 5, a pair of locking pieces 15 extending in a folded shape are provided at the lower end of the support column 14. Both the locking pieces 15 are arranged on both sides of the support column 14 and extend in a direction away from the support column 14 as they go upward from the lower end of the support column 14. Further, both the locking pieces 15 can be elastically bent in a direction approaching the column 14. Locking claws 16 projecting upward are provided at the upper ends of the locking pieces 15. When the clip 11 is inserted into the mounting hole H, the upper ends of both locking pieces 15 are locked to the hole edge of the mounting hole H from below, and the locking claw 16 is engaged with the inner wall of the mounting hole H from the inside in the radial direction. The clip 11 is fixed to the panel P by stopping.

  As shown in FIG. 3, a standing wall portion 19 that rises upward is provided at the rear end of the base portion 13. The insertion piece 12 is disposed so as to face the base portion 13 so as to extend forward from the upper end of the standing wall portion 19. The insertion piece 12 is formed with a locking hole 17 into which the locking projection 38 of the cassette portion 37 is fitted. A front side portion of the locking hole 17 in the insertion piece 12 is a locked portion 18 that locks in the front-rear direction with the locking projection 38. Therefore, when the insertion piece 12 is inserted into the insertion port while sliding from the rear of the cassette portion 37, the locked portion 18 interferes with the locking protrusion 38 and is displaced downward, When the portion 18 gets over the locking projection 38, the locking projection 38 is elastically returned and displaced and fits into the locking hole 17. As a result, the locking projection 38 and the locked portion 18 are locked in the front-rear direction, and the clamp 10 is fixed to the cassette portion 37 of the connector 30.

  When the clamp 10 is removed from the cassette portion 37, the locking protrusion 38 and the locked portion 18 are moved by displacing the locking protrusion 38 below the locking hole 17 using a jig or the like. It is only necessary to release the locked state, and the clamp 10 can be detached from the connector 30 in this way.

  The loop portion 20 is connected to the standing wall portion 19. Further, the loop portion 20 is elastically sandwiched between the lower surface of the terminal holding portion 33 and the upper surface of the panel P from the vertical direction (the radial direction of the loop portion 20). For this reason, the vibration from the vehicle body is absorbed when the loop portion 20 is bent and deformed, and the vibration transmitted to the connector 30 can be suppressed. Here, since the clamp 10 is removable, it can be selected according to the shape of the panel P, and a general-purpose connector 30 can be used.

  Furthermore, the axial direction passing through the axis of the loop portion 20 is orthogonal to the direction in which the clamp 10 is detached from the connector 30. Therefore, when the clamp 10 is detached from the connector 30, it is only necessary to put the finger of the loop portion 20 and pull it backward, and the workability of removing the clamp 10 from the connector 30 is improved.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, in order to attach the clamp 10 to the connector 30, the insertion piece 12 is inserted into the insertion slot of the cassette unit 37 while sliding the clamp 10. At this time, the locked portion 18 of the insertion piece 12 interferes with the locking protrusion 38 of the cassette portion 37 to elastically displace the locking protrusion 38, and the locked portion 18 is locked. At the same time, the locking projection 38 is elastically returned and displaced and fits into the locking hole 17 vigorously. Accordingly, the clamp 10 is fixed to the connector 30 by the locked portion 18 and the locking protrusion 38 being locked in the front-rear direction.

  Next, when the clip 11 is inserted into the mounting hole H, both the locking pieces 15 interfere with the hole edge of the mounting hole H, so that both the locking pieces 15 are elastically deformed to the support column 14 side. At the same time that the stop piece 15 passes through the mounting hole H, both the locking pieces 15 are elastically restored and deformed, and the both locking claws 16 are fitted into the mounting holes H in a posture that penetrates the panel P. In parallel with this, the loop portion 20 is elastically deformed by being sandwiched between the terminal holding portion 33 and the panel P from the vertical direction. Therefore, vibration from the vehicle body is absorbed by elastic expansion and contraction of the loop portion 20. Moreover, when removing the clamp 10 from the connector 30, it can remove easily by putting the finger | toe of the loop part 20 and pulling back.

  As described above, in the present embodiment, even when the shape of the panel P is different for each vehicle type, the clamp 10 that matches the shape of the panel P can be appropriately set, and the general-purpose connector 30 can be used. . Further, it is not necessary to use a complicated configuration as the vibration absorbing portion, and the loop portion 20 can be configured with a simple configuration called a loop shape. Furthermore, since the vibration absorbing portion has a loop shape, a sufficient amount of displacement can be obtained when the loop portion 20 is elastically deformed, and vibration from the vehicle body can be reliably absorbed. Furthermore, the clamp 10 can be easily removed from the connector 30 by inserting a finger of the loop portion 20 and pulling it backward.
