Abstract
A connector housing (10) has a wide cavity group (11L) and a narrow cavity group (11S). A front holder (30) is mounted to the front of the housing (10), but corresponds only to the narrow cavity group (11S). Thus, the front holder (30) has a small area as compared to a front holder corresponding to all the cavities. Accordingly, a degree of shrinkage of the front holder (30) during resin molding is suppressed, thereby making a dimensional variation of the front holder (30) smaller. As a result, displacements between the smaller cavities (12S) and the portions of the front holder (30) corresponding to the smaller cavities (12S) are suppressed.
Claims16
A connector, comprising:
- a housing (10) formed with cavities (12) and locks (13) extending substantially along inner walls of the respective cavities (12);
- the cavities (12) comprising first and second cavity groups (11L, 11S), the first cavity group (11L) having a plurality of cavities (12L) formed with supports (15) for supporting front ends of terminal fittings (20L), and the second cavity group (11S) having cavities (12S) without supports;
- and
- a front holder (30) assembled with the housing (10) and corresponding only to the cavities (12S) of the second cavity group (11S), the front holder (30) including supports (35) for supporting the front ends of terminal fittings (20S) inserted into the cavities (12S) of the second cavity group (11S).
A method of assembling a connector having a housing (10) formed with a plurality of cavities (12) and locks (13) extending substantially along inner walls of the cavities (12), the cavities (12) including a first cavity group (11L) with a first plurality of cavities (12L) formed with supports (15) for supporting front ends of terminal fittings (20L), and a second cavity group (11S) formed with a second plurality of cavities (12S) without supports, comprising the steps of:
- assembling the housing (10) with a front holder (30) formed to substantially correspond only to the second cavity group (11S), thereby forming front ends of the cavities (12S) of the second cavity group (11S) and providing supports (35) for supporting the front ends of the terminal fittings (20S) inserted into the cavities (12S) of the second cavity group (11S), and
- inserting terminal fittings (20) into the corresponding cavities (12) and locking them by the locks (13).
