Electrical connector with stepped housing
First Claim
1. An electrical connector for mounting on a substrate, comprising:
- a housing having a surface that faces the substrate when the connector is mounted on the substrate, the surface having a first and a second portion, the first portion being recessed in relation to the second portion, the housing having pocket walls that define a first and a second pocket formed therein, the first and second pockets extending inward from the respective first and second portions of the surface;
a first contact and a second contact each having a tail extending into the respective first and second pockets; and
a first and a second fusible element attached to the respective first and second tails, wherein the first fusible element is positioned outside of the first pocket so that there is a gap between the first fusible element and the housing surface and the pocket walls, and a portion of the second fusible element is positioned in the second pocket so that the portion of the second fusible element contacts the pocket walls that define the second pocket,wherein ends of the first and the second contacts are substantially coplanar.

Abstract
A preferred embodiment of a ball-grid array connector includes a housing having a major surface with a first and a second portion. The housing has a first and a second penetration formed therein. The first and second penetrations adjoin the respective first and second portion of the major surface. The connector also includes a first and a second contact mounted on the housing and extending through the respective first and second penetrations. The connector further includes a first and a second fusible element attached to the respective first and second contacts. The first portion of the major surface is recessed so that the first fusible element is spaced apart from the housing.

12. A ball-grid array connector, comprising:
-
a housing having a first portion and a second portion, the first portion being recessed relative to the second portion, and one or more pocket walls, disposed in the first portion, that define a pocket; a first contact that is disposed in the pocket and that has an end that extends out of the pocket; and a fusible element attached to the first contact end so that there is a gap between the fusible element and the first portion, wherein the second portion is offset from the recessed portion, the housing further comprises one or more pocket walls that define a second pocket within the housing, and the connector further comprises a second contact having a contact end that is disposed in the second pocket, and a second fusible element attached to the second contact end, extending into the second pocket and contacting the one or more pocket walls that define the second pocket within the housing, and wherein the ends of the first and the second contacts are substantially coplanar. - View Dependent Claims (13, 14, 15)

16. An electrical connector for mounting on a substrate, comprising:
-
a first and a second contact; a first and a second fusible element respectively connected to the first and the second contacts; and a housing having a first portion and a second portion, the first and second contacts being mounted on the housing so that the first and second contacts extend through penetrations associated within the respective first and second portions, wherein the first portion is recessed in relation to the second portion so that there is gap between the first fusible element and the housing whereby the connection formed by the first fusible element can deflect in relation to the housing in response to relative movement between the housing and the substrate, wherein the penetrations are pockets formed in the housing, the connection formed by the second fusible element extends into the penetration associated with the second portion, the pockets are defined by angled pocket walls, and ends of first and the second contacts are substantially coplanar.

17. A ball-grid array connector, comprising:
-
a housing comprising a first and a second portion, the thickness of the first portion being less than the thickness of the second portion, the first portion having a first pocket defined by angled walls, and the second portion having a second pocket defined by angled walls; a first contact disposed in the first pocket and having a contact end that extends outside of the first pocket; a first fusible element attached to the first contact end and being disposed outside of the first pocket; a second contact disposed in the second pocket and having a contact end that is disposed inside of the second pocket; and a second fusible element attached to the second contact end, at least a portion of the second fusible element being disposed in the second pocket; wherein the first contact ends are substantially coplanar with the second contact ends.
