Abstract

A mounting structure of lock pieces on a connector hood includes L-shaped lock piece support portions projecting from side surfaces of the connector hood and having free ends rising upwardly, respectively, and L-shaped window portions provided in the lock pieces and having provisional window portions and complete window portions, respectively. Each of the provisional window portions has a width for receiving one of the L-shaped lock piece support portions and a height much more than a thickness of the L-shaped lock piece support portion. On the other hand, each of the complete window portions is continuous to the provisional window portion at its upper end and has a width and a height somewhat more than the width and the thickness of the L-shaped lock piece support portion, respectively. With this arrangement, the lock pieces are able to be mounted on the metal hood by once inserting the lock pieces into the provisional window portions, respectively, and then moving the lock pieces into the complete window portions of the lock pieces.

Claims

1. A mounting structure of lock pieces on a connector hood comprising, L-shaped lock piece support portions projecting from side surfaces of the connector hood and having free ends protruding therefrom, and L-shaped window portions provided in the lock pieces and having provisional window portions and complete window portions respectively, each of the provisional window portions having a width for receiving a width of one of the L-shaped lock piece support portions and a height greater than a thickness of the L-shaped lock piece support portion, and each of the complete window portions being continuous to the provisional window portion at its upper end and having a width and a height greater than the width and the thickness of the L-shaped lock piece support portion respectively, thereby enabling the lock pieces to be mounted into the provisional window portions and then moving the lock pieces into the complete window portions of the lock pieces.

2. A mounting structure of lock pieces on a connector hood as claimed in claim 1, wherein each of the L-shaped lock piece support portions is located so that one of the side edges thereof is positioned substantially at a center of the connector hood on a side portion thereof, and each of the L-shaped window portions is located so that the boundary of the associated provisional window portion and the complete window portion is located substantially at said center of the connector hood.

3. A mounting structure of lock pieces on a connector hood as claimed in claim 2, wherein the L-shaped lock piece support portions are arranged in rotational symmetrically with respect to a center line of the metal hood.
