Abstract
Abstract An improved electrical connector comprises a plurality of pairs of electrical contact members mounted in an insulative housing. The contacts of each pair are spaced apart to receive a prong of a printed circuit board. Those pairs of contacts which are to remain closed or ''''shorted'''' when the printed circuit board is removed from the connector structure are provided with shorting bar assemblies. Each shorting bar assembly comprises a shorting bar of electrically conductive material which is spring-biased into engagement with each contact of its associated mating pair. When a prong of a printed circuit board is inserted between the mating contacts it will depress the shorting bar, against the action of the spring, into a position which is out of contact with the contact members. When the prong of the printed circuit board is removed the spring of the shorting bar assembly returns the shorting bar to a position which again electrically connects or shorts the pair of mating contacts.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
In a printed circuit board connector assembly comprising an elongated body of insulative material having an elongated opening therein and a plurality of longitudinally spaced pairs of electrical contact members disposed in said elongated opening; each of said contact pairs comprising contacts spaced from one another and bent inwardly toward one another to define a space therebetween for receiving and making electrical contact with a portion of a circuit board inserted into said elongated opening in said elongated insulative body, the improvement comprising: a shorting bar assembly disposed between each of selected pairs of said contacts, said shorting bar assembly comprising a shorting bar of electrically conductive material disposed between said contact members; and spring means normally biasing said shorting bar into contact with each of said contact members to establish electrical connection therebetween; said shorting bar being movable to a position out of contact with said contact members to electrically disconnect said contact members from one another when a circuit board is inserted into said elongated opening in said elongated body of insulative material.
Claim 2
Dependent Claim
175 words
In a printed circuit board connector assembly comprising an elongated body of insulative material having an elongated opening therein and a plurality of longitudinally spaced pairs of electrical contact members disposed in said elongated opening; each of said contact pairs comprising contacts spaced from one another and bent inwardly toward one another to define a space therebetween for receiving and making electrical contact with a portion of a circuit board inserted into said elongated opening in said elongated insulative body, the improvement comprising: a shorting bar assembly disposed between each of selected pairs of said contacts, said shorting bar assembly comprising a shorting bar of electrically conductive material disposed between said contact members; and spring means normally biasing said shorting bar into contact with each of said contact members to establish electrical connection therebetween; said shorting bar being movable to a position out of contact with said contact members to electrically disconnect said contact members from one another when a circuit board is inserted into said elongated opening in said elongated body of insulative material.
Claim 3
Dependent Claim
160 words
An improved electrical connector comprising: a housing of insulative material; a pair of mating contact members of electrically conductive material disposed in said housing for receiving a circuit member therebetween; said contact members having at least a portion thereof inclined toward one another to define a progressively decreasing space therebetween; and a shorting bar assembly disposed between said pair of mating contact members; said shorting bar assembly including a shorting bar of electrically conductive material disposed in said progressively decreasing space, and spring means biasing said shorting bar into electrical contact with a portion of each of said mating contact members; whereby, when a circuit member is inserted between said mating contact members said circuit member will first make electrical contact with said mating contact members, and, upon continued insertion of said circuit member, will depress said shorting bar out of electrical contact with said contact members to electrically disconnect said contact members and said shorting bar from one another.
Claim 4
Dependent Claim
160 words
An improved electrical connector comprising: a housing of insulative material; a pair of mating contact members of electrically conductive material disposed in said housing for receiving a circuit member therebetween; said contact members having at least a portion thereof inclined toward one another to define a progressively decreasing space therebetween; and a shorting bar assembly disposed between said pair of mating contact members; said shorting bar assembly including a shorting bar of electrically conductive material disposed in said progressively decreasing space, and spring means biasing said shorting bar into electrical contact with a portion of each of said mating contact members; whereby, when a circuit member is inserted between said mating contact members said circuit member will first make electrical contact with said mating contact members, and, upon continued insertion of said circuit member, will depress said shorting bar out of electrical contact with said contact members to electrically disconnect said contact members and said shorting bar from one another.
