  The outer wall 75 is formed in a plate shape along the front-rear direction as a whole, and is disposed to face the outside of the inner wall 74 with a certain distance from the inner wall 74. Between the outer wall 75 and the inner wall 74, an entry space 32 into which the second lock portion 44 enters is formed to open upward. The outer wall 75, the inner wall 74, and the entry space 32 are formed in the thickness range in the left-right direction of the middle wall portion 78 (the maximum thickness portion of the mounting wall 73).

  Further, the outer wall 75 can be bent and deformed inward and outward with a portion connected to the side edge of the bottom wall 63 as a fulcrum. The upper end edge of the outer wall 75 is formed by chamfering an inclined surface 33 from both front and rear edges to the inner edge. The outer wall 75 is provided with a rectangular lock hole 34 in a side view. The outer wall 75 forms a portal frame by partitioning the lock hole 34.

  As shown in FIGS. 7 and 11, the attachment portion 65 includes a plate-like base portion 35 integrally connected to the rear end of the bottom wall 63, and a region on the right side (one side in the width direction) of the base portion 35. The projecting portion 36 protrudes upward, and is formed in a substantially L-shaped cross section as a whole. The protrusion 36 is also integrally connected to the rear end portion of the inner wall 74.

  As shown in FIG. 7, a tie band 200 as a fixture that binds and fixes a plurality of electric wires 100 is attached to the attachment portion 65. The tie band 200 is made of a synthetic resin, and includes a square box-shaped head 210 and a band-shaped band main body 220 that is elongated from the head 210.

A plurality of electric wires 100 led out from the electric wire outlet 31 are placed side by side on the electric wire support surface 37 and supported. On the lower surface of the base portion 35, a curved protrusion-shaped rotation guide portion 38 is provided. The band main body 220 of the tie band 200 is wound along the arcuate surface of the circulation guide portion 38.

  As shown in FIG. 7, the protrusion 36 has a substantially square block shape, and has an insertion hole 39 that penetrates the base 35 in the vertical direction. Of the both side surfaces of the protrusion 36, the surface that continues to the side edge of the wire support surface 37 is a restricting surface 41 that is flat in the vertical direction. The restriction surface 41 has a lower end that intersects the electric wire support surface 37 at a substantially right angle, and an upper end that intersects a head support surface 42 described later at a substantially right angle. Of the plurality of electric wires 100 supported side by side on the electric wire support surface 37, the electric wire 100 </ b> A located at the end is restricted from moving in the left-right direction (lateral direction) by contacting the restriction surface 41 of the protrusion 36. The other electric wires 100 are also positioned in the left-right direction.

  The upper surface of the protrusion 36 is a head support surface 42 that is flat in the left-right direction. The head support surface 42 is arranged at a position higher than the electric wire support surface 37. The tie band 200 is circulated from the lower surface of the base 35 to the upper surface of each electric wire 100 after the band main body 220 is inserted into the insertion hole 39 with the head 210 supported by the head support surface 42. The band body 220 is attached to the attachment portion 65 by inserting and locking the front end portion of the band main body 220 to the head portion 210.

As shown in FIG. 9, the second cover 62 is configured integrally with a covering wall 43 and a pair of second lock portions 44 that hang down from both left and right ends of the covering wall 43.
The covering wall 43 is disposed so as to face the bottom wall 63 and has substantially the same shape as the bottom wall 63 in plan view. For this reason, the rear-end part of the coating wall 43 becomes narrow gradually toward back. As shown in FIGS. 3 and 4, the covering wall 43 is positioned in front of the mounting portion 65 except for a part on the rear end side, and the tie band 200 is attached to the mounting portion 65 behind the covering wall 43. Space to do this is secured.

  As shown in FIG. 3, a second curved portion 45 whose side cross-sectional shape is curved in a waveform along the front-rear direction is provided at the central portion (a portion excluding the outer peripheral edge portion) of the covering wall 43. The second curved portion 45 includes a convex-curved second top portion 46 that is positioned at a substantially central portion in the front-rear direction, a second front region 47 that slopes downward from the second top portion 46, and a rear side from the second top portion 46. And a second rear region 48 inclined at a downward slope. The inclination angle of the second front region 47 (inclination angle with respect to the front-rear direction) is substantially the same as the inclination angle of the first front region 68, and the inclination angle of the second rear region 48 is substantially the same as the inclination angle of the first rear region 69. It is. Moreover, the 1st, 2nd top parts 67 and 46 are arrange | positioned in the substantially same position regarding the front-back direction. That is, the first and second bending portions 66 and 45 are in a substantially parallel positional relationship. Here, the space between the first and second curved portions 66 and 45 is configured as a routing space 58 that holds the electric wire 100 by bending (meandering) it in a direction crossing the front-rear direction.

  Further, as shown in FIG. 4, the second bending portion 45 is integrally connected to the outer peripheral edge portion of the covering wall 43 via the second connection wall 49. As shown in FIGS. 3 and 9, a plurality of second protrusions 51 are provided on the lower surface of the second bending portion 45 at intervals in the front-rear direction. The second ridges 51 have a shape that extends in the left-right direction, are provided in the second front region 47 and the second rear region 48, and are arranged at different front and rear positions from the first ridges 72. Yes.

  As shown in FIG. 9, a pair of guide portions 52 project from the left and right sides across the front end portion of the second front region 47 in the lower surface front end portion of the covering wall 43. By inserting the guide portion 52 into the concave groove 77 in a fitted state, the assembling operation of the first and second covers 61 and 62 is guided, and the first and second covers 61 and 62 are positioned relative to each other. The

  The second lock portion 44 extends in the front-rear direction so as to follow the side edge portion of the covering wall 43, and then the rear end portion is bent inwardly toward the rear side. As shown in FIG. It is possible to fit into 64 entry spaces 32. At the front portion (portion along the front-rear direction) of the second lock portion 44, a lock piece portion 54 that is thin by forming a concave portion 53 that is rectangular in a side view on the outer surface is provided so as to be able to bend and deform. . As shown in FIG. 5, an outer wall 75 can be fitted into the recess 53. On the outer surface of the lock piece 54 (the inner surface of the recess 53), there are provided claw-like lock projections 55 that can be fitted and locked in the lock holes 34 of the outer wall 75. The lock protrusion 55 is formed within the depth of the recess 53.

  As shown in FIG. 5, in the region between the second lock portion 44 and the second curved portion 45 in the covering wall 43, the inner wall 74 straddles the outer peripheral edge portion of the covering wall 43 and the second connecting wall 49. A restriction groove 56 having an angular cross section that can be inserted in a fitted state is provided. The restriction groove 56 extends over the entire length of the second lock portion 44 in the front-rear direction, and extends from the outer peripheral edge portion of the covering wall 43 to the second curved portion 45 (second front region 47, second top portion 46, second rear region). It has a depth corresponding to a head up to 48). The left and right groove surfaces of the restriction groove 56 are arranged in the vertical direction, and the groove surface facing the inner wall 74 functions as a pressing surface 57 that restricts the inner wall 74 from falling down.

Next, the function and effect of the first embodiment will be described.
At the time of assembly, the electric wires 100 extending from the inner housing 11 are led out to the outside through the electric wire outlet 31 of the first cover 61 of the strain relief 60. Subsequently, the second cover 62 is assembled to the first cover 61 from above. In the assembling process, the guide portion 52 of the second cover 62 is inserted into the concave groove 77 to be guided, and the second lock portion 44 of the second cover 62 is fitted in the entry space 32 of the first cover 61. enter in. Then, the lock protrusion 55 of the second lock portion 44 slides on the inclined surface 33 of the outer wall 75 of the first lock portion 76, and the outer wall 75 is bent and deformed outward. Thereafter, the outer wall 75 is elastically restored, and the lock protrusion 55 is fitted into the lock hole 34, whereby the second lock portion 44 is locked to the first lock portion 76 as shown in FIG. The two covers 61 and 62 are held in the assembled state. Note that the outer surface of the outer wall 75 is substantially flush with the opening edge of the recess 53 on the outer surface of the second lock portion 44 and does not protrude from the outer surface of the second lock portion 44.

  Further, immediately before the assembly of the first and second covers 61 and 62 is completed, the upper end portion of the inner wall 74 is fitted into the restriction groove 56 of the covering wall 43 of the second cover 62, and the movement of the inner wall 74 in the left-right direction is restricted. Is done. In particular, since the inner wall 74 has the lock piece portion 54 located on the outer side, the inner wall 74 is easily pushed to the inner side by being pushed by the lock piece portion 54, and the upper end portion of the inner wall 74 is in contact with the holding surface 57 of the restriction groove 56. By contacting, the merit which can control the internal fall of the inner wall 74 is large. Further, the second bending portion 45 is formed with a drop from the outer peripheral edge portion of the covering wall 43 so as to form the wiring space 58 of the electric wire 100 between the first bending portion 66, and the restriction groove 56 is used by using the drop. Therefore, a special structure for the restriction groove 56 is not newly provided, and the entire structure can be simplified. Even after the first and second covers 61 and 62 are assembled, the upper end portion of the inner wall 74 is fitted in the restriction groove 56 and the state where the inward fall is restricted is maintained.

  When the first and second covers 61 and 62 are assembled, as shown in FIG. 3, the wires 100 extending from the rear surface of the inner housing 11 are arranged in the routing space 58 between the first and second curved portions 66 and 45. It is routed in a state bent in a substantially S shape. For this reason, even if an external force such as vibration or tension acts on a portion led out from the wire lead-out port 31 of each wire 100, the wire 100 can be used in the routing space 58 between the first and second bending portions 66 and 45. Can be suppressed. As a result, the close contact state between the inner peripheral surface of the cavity 21 and the rubber plug 120 can be maintained satisfactorily and the sealing performance can be secured, and the terminal fitting 90 and the mating terminal fitting are fitted after the housings 10 and 80 are fitted together. The connection state with 85 can be maintained well and connection stability can be ensured. In particular, in the case of the first embodiment, a plurality of first and second ridges 72 and 51 provided respectively on the first and second bending portions 66 and 45 are provided on the outer peripheral surface of the electric wire 100. By closely abutting 72 and 51 so as to bite in, it is possible to reliably prevent the electric wire 100 from being displaced in the front-rear direction in the routing space 58.

  When the first and second covers 61 and 62 are assembled, the lead-out portions of the electric wires 100 are arranged substantially side by side from the routing space 58 to the electric wire support surface 37 of the attachment portion 65 via the electric wire outlet 31 of the strain relief 60. Can be placed. Here, the tie band 200 is attached to the attachment portion 65 as shown in FIG. 7 before and after the assembly work of the first and second covers 61 and 62 described above. The tie band 200 is held by the attachment portion 65 in a temporarily fixed state with the head 210 placed on the head support surface 42 and the band main body 220 passed through the insertion hole 39.

  Subsequently, the band main body 220 extending from the lower end opening of the insertion hole 39 of the attachment portion 65 is circulated from the base portion 35 to the upper end of each electric wire 100 via the circulation guide portion 38, and the distal end portion of the band main body 220 is the head portion. 210 is inserted and locked. Thereby, the band main body 220 is wound over the electric wires 100 from the base portion 35, and the electric wires 100 are sandwiched and fixed in a horizontal row between the band main body 220 and the base portion 35. At this time, the electric wire 100A located at the end abuts against the restriction surface 41 of the protrusion 36, and the displacement of each electric wire 100 in the left-right direction is restricted.

  As described above, according to the first embodiment, since the strain relief 60 integrally includes the attachment portion 65 for attaching the tie band 200 for fixing the electric wire 100, the attachment portion 65 is connected to the strain relief 60. However, the number of parts can be reduced as compared with a case where the parts are provided separately. In addition, since the head support surface 42 and the regulation surface 41 are efficiently provided using the upper surface and side surfaces (two surfaces intersecting each other) of the protrusion 36 of the attachment portion 65, the structure of the attachment portion 65 is simplified. be able to.

  Further, as shown in FIG. 5, the pressing surface 57 of the regulation groove 56 of the covering wall 43 is disposed so as to be able to contact the upper end portion of the inner wall 74 inside the inner wall 74, so that the inner wall 74 is prevented from falling down. Therefore, the stability of the locked state of the first and second lock portions 76 and 44 can be ensured. In this case, since the covering wall 43 is a portion that covers the wiring space 58 of the electric wire 100, it is not necessary to provide a dedicated structure for restricting the inner wall 74 from falling down, and the structure is avoided from becoming complicated. Can do.

<Example 2>
FIG. 12 shows a second embodiment of the present invention. The second embodiment is substantially the same as the first embodiment except for the structure of the first cover 61A of the strain relief 60A, which is different from the first embodiment. For this reason, below, the same code | symbol is attached | subjected to the structure which is the same as that of Example 1, or corresponds, and the overlapping description is abbreviate | omitted.

  In the case of the second embodiment, the first connecting wall 71 is omitted from the first cover 61A, and a cut 59 substantially along the front-rear direction is formed between the outer peripheral edge portion of the bottom wall 63 and the first curved portion 66. Yes. The first bending portion 66 can be bent and deformed in the vertical direction with the front and rear ends serving as fulcrums by making cuts 59 on both sides.

  According to the second embodiment, when the electric wire 100 is sandwiched in the routing space 58 between the first and second bending portions 66 and 45, the first bending portion 66 is in a state where it can be bent and deformed. Assembling errors and dimensional errors between the first and second covers 61A and 62 can be absorbed. In particular, even when the wire diameter is changed, it is possible to respond flexibly. In the case of the second embodiment, if the second connecting wall 49 is omitted from the second cover 62, it becomes difficult to form the pressing surface 57 that restricts the inner wall 74 from falling down, and therefore a cut 59 is formed on the first cover 61A side. It is desirable to form.
