Alternatively, it is possible to sufficiently prevent the rear end from lifting.

  Next, the operation will be described.

  When the electric wire cover 20 is attached to the connector 10 and the electric wire drawn from the back surface 11 of the connector housing is guided in a predetermined direction, the electric wire cover 20 is first held at a position away from the connector 10. Then, the wire is brought close to the electric wire, and all the electric wires are pushed and bent in the direction to be guided while being picked up by the electric wire cover 20 having a substantially U-shaped cross section. At this time, it is easy to work if a bending rod is attached to the electric wire in advance.

  Then, when the electric wire cover 20 is moved closer to the connector 10 while pushing and bending the electric wire and the first guide convex portion 24 on the electric wire cover 20 side is moved to the position where it enters the first inlet 13, the electric wire is resisted against the bending resistance of the electric wire. While pushing down the wire cover 20 in the direction of arrow Y1 in FIG. 3, the first guide protrusion 24 on the wire cover 20 side extends from the first inlet 13 to the first guide groove 12 on the connector 10 side (forward in the drawing). At the same time, the second guide protrusion 25 on the wire cover 20 side is inserted into the second guide groove 15 on the connector 10 side from the second inlet 15a.

  Once inserted, the wire cover 20 is slid in the forward direction indicated by the arrow Y2 in FIG. When the electric wire cover 20 is slid by the predetermined sliding allowance, the rear end wall 23 of the electric wire cover 20 comes into contact with the stopper 19 on the connector 10 side and stops. In this state, the electric wire is surely guided in a predetermined direction, The first and second guide protrusions 24 and 25 are securely engaged with the first and second guide grooves 12 and 15, so that the electric wire cover 20 is fixed and prevented from coming off.

With the front end of 20 positioned near or beyond the center position of the length in the sliding direction of the back surface 11 of the connector housing, the wire cover 20 is placed on the back surface of the connector from the direction perpendicular to the back surface 11 of the connector housing. Since it is provided at a position where it can be covered, the electric wire cover 20 can be engaged with the connector 10 after being held in the vicinity of the center of the connector 10 in advance without being engaged from the end of the connector 10.

  That is, when the electric wire cover 20 is put on the back surface of the connector 10, the electric wire cover 20 can be moved to the vicinity of the center at a position away from the connector 10 without strongly pressing the electric wire. The wire cover 20 is engaged with the connector 10 by inserting the first guide protrusion 24 from the first inlet 13 into the first guide groove 12 only after reaching the vicinity or beyond the center position. Can do. Then, by sliding the front wire cover 20 further from the position where the first guide protrusion 24 is inserted into the first guide groove 12 from the first inlet 13, while pressing the wire by the wire cover 20, a predetermined direction The electric wire can be smoothly guided toward

  Therefore, compared to the case where the electric wire cover 20 is engaged from the end of the connector 10 and is slid to the opposite end to guide the electric wire in a predetermined direction, the distance (the electric wire cover 20 that slides the electric wire cover 20 while pressing the electric wire). Assembly stroke) can be shortened, and the risk of damaging the wire due to friction can be reduced by shortening the distance that the wire cover 20 and the wire rub against each other.
