ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present application relates to electrical connectors and more particularly to methods for manufacturing electrical connectors.
2. Brief Description of Prior Developments
In various electrical connectors particular needs require the use of relatively long beams. The physical relationship of the cross sectional area of the beam and its length will make it difficult to manage more critical dimensional tolerances. The critical dimensional tolerances in question control the inner relationship between the terminal tail, the retention feature and the contact area of the terminal. An example of such an electrical connector is a receptacle used on a single connect attach (SCA) disk drive interface.
There is, therefore, a need for means for managing critical tolerances in connectors having such cross sectional area to length relationships.
It is also known that the use of a relatively long beam will generally require the use of a relatively high insulative housing. It is found, however, that such extended height insulative housings or other atypical height to width ratio housings may have a tendency to bow or warp during molding.
There is, therefore, a need for a method of molding extended height insulative housings.
SUMMARY OF THE INVENTION
The present invention is a receptacle for an electrical connector which comprises an elongated insulative housing having parallel lateral walls, parallel end walls and base wall. An interior cavity is formed by those walls, and a longitudinal groove extends between the longitudinal walls from adjacent one of said end walls to the other end wall. At least one conductive contact having a base end and a distal end extends upwardly in the interior cavity. It is fixed to the housing adjacent the base end and is attached at a medial guide means and then extends upwardly such that the distal end of the contact is adjacent the longitudinal groove.
Also encompassed by the present invention is a method for molding an insulative housing for an extended height housings in which a transverse flow restriction means is provided to eliminate or reduce bow and warp in the housing.
