BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to a receptacle contact for mounting to contact pins to adapt the contact pins to a receptacle contact e.g. for use with pressed screen pin contacts.
2. Summary of the Prior Art
Fuse and relay boxes of automobiles often comprise pressed screen contact sheets from which flat tab contacts are stamped. The pressed screens are flat sheets of metal out of which a multitude of circuits are stamped for interconnecting various components to fuses and relays. Tabs are stamped, usually orthogonally, from the press screen for connection of the circuits thereof to connectors of cable assemblies leading to various components of the vehicle. Many different types of contacts need to be connected to the various circuits of the press screen, depending on the electric current requirements and the available space. It is easy to stamp pin and tab contacts from such press screens, however certain receptacle contacts, particularly miniature receptacle contacts having closed box-shaped bodies, are very difficult to produce directly from the press screen. In certain cases it is necessary to have receptacle contacts on the press screen and these can be assembled to tab or pin contacts on one end and provide a receptacle contact at the other end for connection to complementary pin or tab contacts of connectors.
It is of course a continuous requirement to produce such receptacle contacts in the most compact and cost-effective manner that can be quickly, easily, and safely assembled to the pressed screen. It is also often desirable to produce miniature receptacle contacts for pressed screens that can receive pin contacts with good electrical characteristics therebetween.


SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide a miniature receptacle contact for adapting pin contacts into receptacle contacts in a cost-effective, reliable and compact manner.
The object of this invention has been achieved by providing a receptacle contact having a pin mounting section extending axially into a complementary pin contact section, wherein the mounting section comprises a bottom wall, a pair of side walls extending from lateral edges thereof, and a pair of top half-walls extending from the side walls towards each other and forming a seam therebetween, each of the walls having contact protrusions extending inwardly for forming a pin receiving cavity for tightly receiving a pin therein, the side walls separated from the bottom wall by axially extending slots and the side walls separated from the top half walls by axially extending slots, the slots enabling inward deformation of the mounting portions. Embodiments may include provision of U-shaped top half walls having their free ends directed into the mounting section towards the bottom wall thereby forming a contact surface opposing the bottom wall contact surface for tightly receiving the complementary pin contact therebetween.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-6, an electrical receptacle contact 2 comprises a pin mounting section 4 extending axially into a box-shaped body section 6 which extends axially into a pin receiving contact section 8. The body section 6 comprises a bottom wall 10, side walls 12 and 14 extending substantially orthogonally from lateral edges thereof and a top wall 16 extending from one side of the wall 12 towards the other side wall 14 and attached thereto by a laser weld 18. Contact arms 20,22,24 and 26 extend from the top, side and bottom walls 16,12,14 and 10 respectively towards a pin-receiving mating end
