Connector and cover therefor
First Claim
1. A connector, comprising:
- a connector housing (11;
41) formed with a plurality of terminal cavities (18;
42) for housing terminal fittings (13;
44), elastic engaging members (17) in proximity to said respective terminal cavity (18;
42), said elastic engaging members (17) being displaceable into a deformation permitting space (20) during insertion of the respective terminal fittings (13;
44) into the terminal cavities (18) and elastically moving out of said deformation permitting space (20) upon complete insertion of the respective terminal fitting (13),a cover (23;
50) fittable on an end of the connector housing (11;
41) where connection ends of the terminal fittings (13;
44) are arrangeable,a locking mechanism (21, 22, 25;
60,
52) for holding the cover (23;
50) in a first mount position where the cover (23;
50) is at least partly engaged with an end of the connector housing (11;
41) and in a second mount position where the cover (23;
50) is more deeply engaged with the connector housing (11;
41) than in the first mount position,at least one joint terminal (28;
15) mounted in the cover (23;
50), the joint terminal (28;
15) being spaced from the terminal fittings (13;
44) when the cover (23;
50) is in the first mount position, and contacting the terminal fittings (13;
44) when the cover is in the second mount position, andan insufficient insertion detection member (30) integrally formed with the cover (23) for projection into the deformation permitting space (20) when the cover (23) is in the second mount position, said insufficient insertion detecting member (30) being blocked by any of said elastic engaging members (17) in the deformation permitting space (20), thereby preventing movement of the cover (23;
50) into the second mount position and indicating incomplete insertion of at least one said terminal fitting (13).

Abstract
The invention is designed to reduce a production cost by reducing the number of operation steps during assemblage. Female terminal fittings 13 connected with coated wires 12 are inserted into a connector housing 11, and are prevented from coming out of the connector housing 11 by engagement with elastic engaging members 17. First and second locking projections 21, 22 project from each of the upper and lower wall surfaces of the connector housing 11. On the other hand, the cover 23 is formed with an engaging frame 25 engageable with the first and second locking projections 21, 22 of the connector housing 11. A joint terminal 28 is integrally mounted in the cover 23 by means of insert molding. Insufficient insertion detecting members 30 can enter deformation permitting spaces 20 for the elastic engaging members 17 of the connector housing 11.
