  • an excessive displacement restriction portion 22a is provided on the inner face of the connecting arm 22 of the lever 20.
  • the excessive displacement restriction portion 22a comes closer to the lock arm 45 and restricts the excessive outward bending of the lock arm 45 when the lever 20 is being held at the temporary-locking position.

  • a lock portion 55a is provided in the half end of the lock plate 55 toward the electrical wire guide 53 to engage with the lock arm 45 of the matt seal cover 40.
  • the opposite half end of the lock plate 55 to the electrical wire guide 53 configures an insertion portion 55b, corresponding to disengagement prevention means, which is to be inserted into a disengagement prevention portion 48, corresponding to disengagement prevention means, provided in parallel with the lock arm 45 at each of the top and bottom outer peripheral faces of the pressing plate 42 of the matt seal cover 40.
  • a space between the pair of the top and bottom side walls 51 a of the main cover 51 of the electrical wire cover 50 is slightly wider than the distance between the top and bottom outer peripheral faces (side walls) 42a of the pressing plate 42 of the matt seal cover 40 so that the electrical wire cover 50 can accommodate multiple electrical wires more easily when being attached in the matt seal cover 40.
  • the pair of the top and bottom lock plates 55 is also, along with the wider space between the side walls 51a, configured to be slightly wider than the distance between the top and bottom lock arms 45 in the matt seal cover 40 so that it is not easy to engage the lock portion 55a with the lock arm 45 as it is. Therefore, the lock portion 55a can be engaged with the lock arm 45 while the space between the lock plates 55 remain narrow by narrowing the space between the pair of the lock plates 55 and inserting the insertion portion 55b into the disengagement prevention portion 48.
  • the lock portion 55a is a portion which comes into contact with the engagement convex portion 45c of the lock arm 45, when attaching the electrical wire cover 50, to push the lock arm 45 outward and slide in while bending the lock arm 45 outward, and then fully engages with the engagement convex portion 45c of the lock arm 45 when the lock portion 55a completely passes through the engagement convex portion 45c and thus the lock arm 45 elastically returns inward to the original position.
  • the lock portion 55a restricts the electrical wire cover 50 from moving in the opposite direction of the attaching direction.
  • the excessive displacement restriction portion 22a of the lever 20 is arranged in a place where the excessive displacement restriction portion 22a allows the lock arm 45 to be bent sufficiently when the lock arm 45 is bent by the insertion of the lock plate 55.
  • the disengagement prevention portion 48 of the matt seal cover 40 consists of pressing plates 48a and reinforcing walls 48b.

  • the reinforcing walls 48b reinforce the pressing plates 48a by connecting one end thereof with the top and bottom of the outer peripheral face of the pressing plate 42 and thus resemble substantially an 'L' if seen from the rear side of the insertion direction of the lock plate 55 of the electrical wire cover 50.
  • engagement portions 52a and 47 are provided respectively at the front end of the end wall 52, which corresponds to the other side wall, of the electrical wire cover 50 and at either of the right and left sides of the outer peripheral face, which corresponds to the other side wall, of the pressing plate 42 of the matt seal cover 40, which is the counterpart of the front end of the end wall 52, to engage with each other and thus form a rotation center when attaching the electrical wire cover 50.
  • the disengagement prevention portion 48 and the insertion portion 55b which are disengagement prevention means are placed closer to the engagement portions 52a and 47 than the lock arm 45 and the lock portion 55a which are locking means so that the insertion portion 55b starts to be inserted into the disengagement prevention portion 48 before the engagement between the lock portion 55a and the lock arm 45 starts when the electrical wire cover 50 is rotated toward and attached in the matt seal cover 40.
  • the lever 20 is assembled to the connector housing 10A which configures the connector 10 and the matt seal 30 is fitted into the inner peripheral face of the cylindrical wall 13 of the connector housing 10A at the rear so that the matt seal cover 40 is fixed to the rear of the connector housing 10A while pressing the matt seal 30 (refer to Fig. 4 ).

  • the lock portion 55a of the electrical wire cover 50 comes into contact with the front end of the lock arm 45 and bends the lock arm 45 outward. If the electrical wire cover 50 is further rotated, as shown in Fig. 4 , the lock portion 55a is engaged with the engagement convex portion 45c of the lock arm 45 when the electrical wire cover 50 is properly attached in the matt seal cover 40 so that the electrical wire cover 50 gets tightly locked.
  • the lock arm 45 can be excessively bent outward and thus fractured.
  • the excessive displacement restriction portion 22a is provided at the connecting arm 22 of the lever 20 to intervene in regard to the lock arm 45 when the lock arm 45 is to be excessively bent outward so that it is possible to prevent the lock arm 45 from being bent excessively.

  • the present invention is extremely useful in the electrical wire cover to prevent the fracture of the lock arm by restricting the excessive bending of the lock arm when releasing the electrical wire cover from the locking state.
