Abstract

A connector assembly for an integrated circuit includes two interengaging connector components. One of the components (1) has a chip receiving socket that receives the integrated circuit (41) while the other component (21) has a wire receiving socket that receives at least one array of wires (99). Each component further includes a plurality of conductive terminals (3,23) that engage the integrated circuit or the wires. The terminals of the other component have their contact portions (29) offset. Two of the terminals of the one component are interconnected so they have two contact blades (10) but only one IC engaging contact (8) whereby a single lead (42) of the IC may be electrically joined to a pair of the wires (99), the voided contact spring region being for alignment with a dummy lead of the IC. The terminals (3,23) are formed in a single die and simultaneously inserted into their respective housings in order to simplify the manufacturing process.

Claims

1. An electrical connector for effecting an electrical connection between an integrated circuit and a second, mating electrical connector, comprising:

a connector housing having a nest portion for receiving said integrated circuit therein and an engagement portion for engaging said second, mating electrical connector, said connector housing including at least one passage extending therethrough;

a plurality of conductive terminals disposed in said passage and extending between said nest portion and said engagement portion, said terminals having distinct first and second contact portions and a body portion for retaining said terminals within said housing and located between said first and second contact portions, each said first contact portion including a contact spring that springingly engages a lead of said integrated circuit upon insertion of said integrated circuit into said nest portion and each said second contact portion including a contact blade for engaging a mating terminal of said second mating electrical connector upon mating said first and second electrical connectors, one of said terminals having only a single contact spring, a pair of spaced apart, generally parallel contact blades and a body portion substantially wider than the body portions of others of said terminals whereby an electrical circuit may be established between a single one of said leads of the integrated circuit and a pair of the mating terminals of the second electrical connector.

2. The electrical connector of claim 1, wherein said engagement portion includes a receptacle portion for receiving a plug portion of said second electrical connector.

3. The electrical connector of claim 2, wherein said contact blades extend into said receptacle portion such that upon insertion of said plug portion into said receptacle portion, terminal contact springs of said plug portion springingly engage said contact blades within said receptacle.

4. The electrical connector of claim 1, wherein said nest portion includes a pair of spaced-apart walls separated by an intervening space dimensioned to received said integrated circuit.

5. The electrical connector of claim 1, wherein one of said contact blades is longer than others of said contact blades.
