Abstract
ABSTRACT
An electrical connector for connecting a planar ;ead;ess electronic component package to a substrate, comprises a housing of electrically insulating material carrying a plurality of resilient electrical contacts, and having a lid which, when closed, serves to urge the package into engagement with the contacts, the lid carrying spring members which engage a package mounted on the connector when the lid is closed, thereby to enhance the engagement between the first contact points of the contacts and the conductors on the package. The contacts are received in individual cavities in walls of the housing, the contacts at each wall being retained in their cavities by a common securing arrangement.

Description
This in~ention relates to an electrical connector for connec-ting a planar leadless electronic component package to a substrate.
Electronic components such as integrated circuit chips are frequently mounted on a planar electrically insulating substrate of, for example, ceramic material, the substrate having thereon conductors connected to contact points on the component, and serving for establishing connections between the component and external circuitry.
It i5 often necessary to mount such an elec-tronic component and substrate leadless package on a further substrate such as a printed circuit board, with the conductors of the package electrically connected to conductors on the further substrate.
Many forms of electrical connector for effecting such mounting are well known, and a common type comprises a housing of electrically insulating material, in the form of a frame, carrying a plurality of resilient electrical contac-ts, arranged in individual pockets in the housing walls.
Each contact has a first contact point for engagement with a conductor on the package and a second contact point for engagement with a conductor on the substrate, all the first contact ~.

Such connectc)rs are also known, wh.iceh include a lid hin~ed]..y connectecl to the hous.Lng, which lid when closed on~o the housing serves to urge a package mounted on the housing, into enga~ement with the first contact points of the contacts r and to secure the package to tlle connector.
A difficult~ which arises with known connectors is that since the conductors on the package are not resilient, the contact fQrce between these conductor.s and the contacts is dependent solely upon the resiliency of the contacts, ~nd the accuracy o the positioni.ny of the contacts in the housing.
~ccording to this invention, there is provided an electrical connector for connecting a planar leadless electronic component package to a substrate; comprising a housing of electrically insulat:ing materi.al carrying a p].urality o resilient electri.ccll contacts each haviny a first contact point for engagement ~ith a con~uctc)r on the package and a second contact pOi.llt for engagement ~lith a conductor on the ..~.

The connector comprises a housing 1 moulded from electrically insulating plastics material in the form of a rectanguloid box having four side walls 2 and a base 3. Each side wall 2 is formed with a plurality of cavities 4 separated by partitions 5, each of which cavities 4 receives an electrical contact 6. As best seen in Figure 2, each contact 6 is substantially S-shaped, the upper l.imb 7 providing a first contact point 8 for engagement with a conduc-tor 101 on the Rackage 100, and the lower limb 9 providing a second contact point 10 for engagement with a conductor 201 on the prin-ted circuit board 200. All the first contact points 8 lie substantially in a first plane, and all the second contac-t points 10 lie substantially in a second plane, spaced from7 and parallel to, the first plane, the first plane being defined by the conductor-carrying surface of the package 100 when mounted on the connector, and the second plane being defined by the conductor-carrying surface of the printed ci.rcuit board 200.
