It consists of 72. The inner front end surface 72 and the outer rear end surface 68 are arranged at the same height in the vertical direction.

The opening at the front end of the lower return wiring portion 55 is closed by a closing wall 73 integrally connected to both front ends of the lower inner wall portion 66 and the lower outer wall portion 67. The closed wall 73 is provided with a flat plate-shaped projecting piece portion 74 projecting upward. When the first cover 21 and the second cover 22 are combined, the tip end portion (upper end portion) of the projecting piece portion 74 abuts on each electric wire 90, and each electric wire 90 is pressed against the electric wire side surface 37 of the upper return wiring portion 26. It is possible. Further, when the first cover 21 and the second cover 22 are combined, the projecting piece portion 74 enters between the upper inner wall portion 44 and the upper outer wall portion 45, and the left and right ends of the projecting piece portion 74 are the upper inner wall portion 44 and the upper side. By being arranged so as to be in contact with the outer wall portion 45, the upper inner wall portion 44 and the upper outer wall portion 45 can be in a normal upright posture without falling inward.

The lower inner wall portion 66 is provided with an elastic lock portion 59C projecting upward on the surface side facing the space portion 27 with the lower covering portion 52.
The outer surface of the lower outer wall portion 67 is arranged along the front-rear direction and the up-down direction, and has an elastic lock portion 59D at a substantially central portion in the front-rear direction. The lower end of the elastic lock portion 59D is flattened on the outer surface of the lower outer wall portion 67, and protrudes upward from the lower end portion to the outer rear end surface 68. The elastic lock portion 59D is arranged so as to be displaced rearward from the elastic lock portion 59C of the lower inner wall portion 66.

Further, a pair of guide walls 75 are provided on both front and rear sides of the outer surface of the lower outer wall portion 67 with the elastic lock portion 59D interposed therebetween. The lower end of both guide walls 75 is flattened on the outer surface of the lower outer wall portion 67, and has a flat plate shape protruding from the lower end portion above the outer rear end surface 68 and the outer front end surface 69, respectively. .. Both guide walls 75 have rigidity that does not substantially bend and deform. Due to the step between the outer rear end face 68 and the outer front end face 69, the tip (upper end) of the guide wall 75 protruding from the outer front end face 69 is above the tip of the guide wall 75 protruding from the outer rear end face 68. It is located in a staggered manner. When the first cover 21 and the second cover 22 are combined, the guide walls 75 are arranged so as to come into contact with the guide portions 48 so as to cover the guide portions 48 from the outside. The protruding dimension and the front-rear width dimension of the guide wall 75 are substantially the same as the protruding dimension and the front-rear width dimension of the elastic lock portion 59D.

As shown in FIG. 9, on the upper end surface of the lower outer wall portion 67, the positions of the outer rear end surface 68 and the outer front end surface 69 on both front and rear sides of the elastic lock portion 59D and inside both guide walls 75, respectively. A pair of guide receiving portions 76 are provided so as to be open. Both guide receiving portions 76 have a bottomed concave shape extending in the front-rear direction along the inner surface of both guide walls 75. The inner surface of the guide wall 75 is provided with a shallow groove-shaped recess 83 that extends in the vertical direction and communicates with the guide receiving portion 76 without a step. When the first cover 21 and the second cover 22 are combined, the guide portions 48 corresponding to both guide receiving portions 76 are fitted and inserted.

Next, the action and effect of the first embodiment will be described.
First, the second cover 22 is turned upside down, the fitting rib 35 of the mounting portion 23 is slid-inserted into the fitting groove 14 of the housing 10, and the housing 10 is positioned and held in the mounting portion 23 of the second cover 22 ( See FIG. 6). At this time, each electric wire 90 drawn from the rear surface of the housing main body 11 is arranged in a substantially U shape from the wide base portion 36 of the upper introduction portion 24 to the inclined base portion 43 and the protruding base portion 51 via the base portion 39. At the upper bent portion 25, the wiring direction of each electric wire 90 is reversed from the rear to the front, and each electric wire 90 is rotated along the inner surface of the inner portion 41. Further, each electric wire 90 is inclined toward the side opposite to the upright direction of the inner portion 41 by being arranged along the inclined base portion 43. Therefore, it is possible to prevent each electric wire 90 from floating beyond the tall inner portion 41.

Subsequently, the first cover 21 covers the second cover 22 so as to cover each electric wire 90. When the first cover 21 and the second cover 22 are combined, the side plate portion 63, the concave portion 64, the continuous side plate portion 65, the lower inner wall portion 66, and the lower outer wall portion 67 of the first cover 21 are respectively the second cover 22. The tips of the side portions 38, the inner portion 41, the outer portion 42, the upper inner wall portion 44, and the upper outer wall portion 45 are arranged so as to abut each other. In this case, since the floating of each electric wire 90 in the bent state is suppressed by the heightening of the inner portion 41 and the inclination of the inclined base portion 43, the floating of the butt ends of the first cover 21 and the second cover 22 is suppressed. It is possible to prevent each electric wire 90 from getting caught. Moreover, the projecting piece portion 74 presses each electric wire 90 against the surface 37 along the electric wire, so that the floating of each electric wire 90 is more reliably prevented. Further, when the first cover 21 and the second cover 22 are combined, the rear end portion of the housing body 11 is fitted into the fitting recess 57 of the first cover 21.

In the process of combining the first cover 21 and the second cover 22, the elastic lock portions 59A to 59D slide the corresponding lock portions 33A to 33D and are flexed and deformed to the outside. Further, both guide portions 48 of the second cover 22 slide on the recess 83 of both guide walls 75 of the first cover 21, and the upper outer wall portion 45 of the second cover 22 has both guide walls 75 and the projecting piece portion 74. It is sandwiched between the two in the thickness direction and guided. As a result, the assembling operation of the first cover 21 is also guided, and both guide portions 48 are smoothly inserted into the corresponding guide receiving portions 76 via the guide slope 49. Further, the guide projecting piece 58 of the first cover 21 is inserted so as to fit into the corresponding guide groove 32.

When the first cover 21 and the second cover 22 are combined, the elastic lock portions 59A to 59D are elastically restored, and the lock portions 33A to 33D corresponding to the lock holes 61 are fitted and locked. Further, on the side corresponding to the lower outer wall portion 67 and the upper outer wall portion 45, the elastic lock portion 59D sandwiches the portion locked to the lock portion 33D, and both guide portions 48 have a normal depth to the corresponding guide receiving portion 76. (See FIGS. 3 and 4). As a result, the lower outer wall portion 67 of the first cover 21 and the upper outer wall portion 45 of the second cover 22 are in a state of being tightly connected without being displaced.

Assuming that each electric wire 90 vibrates or the like so that the lower outer wall portion 67 opens outward, an external force acts on the elastic lock portion 59D of the lower outer wall portion 67 in a direction deviating from the lock portion 33D of the upper outer wall portion 45. Even so, the uneven fitting state of both guide portions 48 and both guide receiving portions 76 is maintained so as to resist the external force. Therefore, the lower outer wall portion 67 does not open outward to inadvertently release the locked state between the elastic lock portion 59D and the lock portion 33D, and the combined state of the first cover 21 and the second cover 22 is maintained. Can be maintained well.

As described above, the electric wire cover 20 is attached to the housing 10 to form a connector. Since each electric wire 90 is not arranged in the rear space of the connector, when the connector is attached to an attachment target (not shown) such as a vehicle, the wall surface or parts of the vehicle can be arranged in the rear space. Further, as shown in FIG. 5, the peripheral component 100 can be arranged in the space in front of the closing wall 73 by utilizing the inclination of the inclined base portion 43, which is excellent in space efficiency.

As described above, according to the first embodiment, when the first cover 21 and the second cover 22 are combined, the guide receiving portion 76 receives the guide portion 48, so that the elastic lock portion 59D is separated from the lock portion 33D. Since elastic deformation is restricted in the direction of elasticity, even if an external force acts on the first cover 21 and the second cover 22, the locked state between the elastic lock portion 59D and the lock portion 33D is inadvertently released. It is possible to maintain a good combined state of the first cover 21 and the second cover 22.

In particular, in the case of the first embodiment, the first cover 21 and the second cover 22 have a substantially U-shaped lower bending portion 54 and upper bending for arranging each electric wire 90 drawn from the rear surface of the housing body 11 in a bent state. It has a lower bending portion 54, a lower bending portion 54, and a lower returning wiring portion 55 and an upper returning wiring portion 26 arranged in parallel with the housing 10 from the upper bending portion 25 to the end on the exit side. Since the lower outer wall portion 67 and the upper outer wall portion 45 that cover each electric wire 90 from the outside are provided in the wiring portion 55 and the upper return wiring portion 26, respectively, the lower outer wall portion 67 and the upper outer wall portion 45 are provided. The situation that the lower outer wall portion 67 and the upper outer wall portion 45 are easily opened when the reaction force of each of the electric wires 90 bent in the lower bent portion 54 and the upper bent portion 25 acts and each electric wire 90 vibrates outward. There is. Therefore, the lower outer wall portion 67 and the upper outer wall portion 45 are provided with the guide receiving portion 76 and the guide portion 48, respectively, and there is a great merit that the lower outer wall portion 67 and the upper outer wall portion 45 can be prevented from being deformed. It becomes.

Further, since the guide portion 48 and the guide receiving portion 76 are arranged on both front and rear sides of the lock portion 33D and the elastic lock portion 59D, the elastic lock portion 59D is elastically deformed in the direction of being separated from the lock portion 33D. More reliably regulated.

Further, since the guide receiving portion 76 has a concave shape for receiving the guide portion 48 in the fitted state, the guide portion 48 is restricted from floating with respect to the guide receiving portion 76, and the first cover 21 and the second cover are restricted. Even if 22 receives an external force, it becomes more difficult to shift its position depending on the direction in which it intersects the coalescence direction.
