  • the engagement of the wire cover 20 with the female housing 10 can be effected easily, and also the bending of the wire harnesses H is effected by leverage in which the retaining portion 10K1 serves as the fulcrum, and therefore the worker can effect this bending operation without using a considerable force. Therefore, (i) the accurate positioning, etc., as in Patent Literature 1 are not necessary, and therefore the productivity can be enhanced, and (ii) the risk of damaging the wires as in the earlier invention is eliminated. Furthermore, (iii) the cover-equipped connector of the present invention has backlash prevention shapes for preventing the backlash in three directions, which could not be achieved by the earlier invention. The backlash prevention shapes will be described below. Here, "three directions" are defined as follows with respect to Fig. 1.
  • First one of the three directions is the upward-downward direction of the female housing 10 (hereinafter referred to as "upward-downward direction”).
  • Second one of the three directions is the widthwise direction of the female housing 10 (hereinafter referred to as “left-right direction”).
  • Third one of the three directions is the depthwise direction of the female housing 10 (hereinafter referred to as “forward-rearward direction”).
  • a pair of projections 10G1 are formed respectively at the right and left side walls of the connector housing 10, and each projection 10G1 has taper T1 , and is tapering toward its distal end, and projects toward the wire cover 20.
  • the tapering projection 10G1 having the taper T1 has a triangular shape.
  • a pair of tapering groove portions 20G1 are formed at the wire cover 20, and can be engaged respectively with the tapering projections 10G1.
  • each tapering projection 10G1 is engaged with the corresponding tapering groove portion 20G1 , thereby preventing the movement of the wire cover 20 in the upward-downward direction indicated by arrow R4, thus preventing the backlash of the wire cover 20 in the upward-downward direction.
  • a pair of backlash prevention-shape portions 10G2 are formed respectively at the right and left side walls of the female housing 10.
  • This backlash prevention-shape portion 10G2 is defined by a recess 10G2 having taper T2 and formed in the tapering projection 10G1
  • this tapering recess 10G2 is defined by a pair of tapering faces opposed to each other in a direction of the thickness of the tapering projection 10G1 (that is, in the left-right direction).
  • a pair of protrusions 20G2 each having the same taper T2 as the tapering recess 10G2 are formed respectively at the tapering groove portions 2OG 1 of the wire cover 20, and can be engaged respectively with the tapering recesses 10G2.
  • each tapering projection 10G1 is engaged with the corresponding tapering groove portion 20G1 , and also the backlash prevention-shape tapering recesses 10G2 formed respectively at the right and left tapering projections 10G1 are engaged respectively with the backlash prevention-shape protrusions 20G2 formed respectively at the right and left tapering groove portions 20G1 , and therefore the movement of the wire cover 20 in a direction of arrow R5 is prevented, and therefore the backlash of the wire cover 20 in the left-right direction is prevented.
  • a step portion d1 is formed on the female housing 10, and with this construction the distal end of the wire cover 20 abuts against this step portion d1 , and therefore can not advance any further. Therefore, even if a backlash g1 exists between the retaining portion 10K1 of the female housing 10 and the retaining portion 20K1 of the wire cover 20, the backlash in the direction of arrow R6 is restrained.
