Abstract
Abstract A member (13) with a shorting contact (14) thereon is disposed in a receptacle housing (11). The shorting contact (14) is in mating electrical contact with an interface (15). When a header (12) is inserted into the receptacle housing (11), an inclined portion (29) of a beam (28) formed on the header (12) deflects the shorting contact (14) and opens the electrical circuit between the shorting contact (14) and the interface (15). Male pin contacts (25) in the header (12) electrically engage female contacts (21) within the receptacle housing (11) before the shorting circuit is broken. When the header (12) is removed from the receptacle housing (11) the shorting circuit is closed before electrical contact is opened between the male pin contacts (25) and the female contacts (21). In this manner, spurious signals are prevented. Extension means (32) extending from the sides of the beam (28) are disposed between the shorting contacts ( 14) and the interfaces (15) assuring the opening of the shorting circuit when the header (12) is inserted in the receptacle housing (11).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
204 words
In an electrical shorting system in a receptacle housing wherein a member having a shorting contact thereon is in mating electrical contact with an interface, the receptacle housing further having a female contact formed thereon, the receptacle housing removably receiving therein a header having a male pin formed thereon, said female contact electrically cooperating with said male pin when the header is inserted into the receptacle housing, the improvement comprising: the header having a beam formed thereon to engage the member when the header is inserted into the receptacle housing such that the shorting contact on the member is deflected from mating electrical contact with the interface thereby opening electrical contact between the shorting contact and the interface, the member having means thereon to receive said beam on the header, such that when the header is inserted into the housing receptacle, the electrical contact is formed between the female contact and the male pin before the shorting contact is deflected from the interface and when the header is removed from the receptacle housing, electrical contact is formed between the shorting contact and the interface before electrical contact is broken between the female contact and the male pin, thereby preventing spurious signals from being transmitted.
Claim 2
Dependent Claim
204 words
In an electrical shorting system in a receptacle housing wherein a member having a shorting contact thereon is in mating electrical contact with an interface, the receptacle housing further having a female contact formed thereon, the receptacle housing removably receiving therein a header having a male pin formed thereon, said female contact electrically cooperating with said male pin when the header is inserted into the receptacle housing, the improvement comprising: the header having a beam formed thereon to engage the member when the header is inserted into the receptacle housing such that the shorting contact on the member is deflected from mating electrical contact with the interface thereby opening electrical contact between the shorting contact and the interface, the member having means thereon to receive said beam on the header, such that when the header is inserted into the housing receptacle, the electrical contact is formed between the female contact and the male pin before the shorting contact is deflected from the interface and when the header is removed from the receptacle housing, electrical contact is formed between the shorting contact and the interface before electrical contact is broken between the female contact and the male pin, thereby preventing spurious signals from being transmitted.
Claim 3
Dependent Claim
43 words
The electrical shorting system of claim 1, further comprising the member having a leg, the leg having a top, the shorting contact being formed thereon, the shorting contact making electrical contact with the interface when the header is removed from the receptacle housing.
Claim 4
Dependent Claim
57 words
The electrical shorting contact of claim 2, wherein the beam on the header has an inclined portion formed thereon, the inclined portion contacting the leg having the shorting contact thereon when the header is inserted into the receptacle housing so that the top of leg having the shorting contact is deflected from electrical contact with the interface.
Claim 5
Dependent Claim
51 words
The electrical shorting contact of claim 1, wherein the beam has a first side and a second side, an extension means being formed on each respective side of the beam, said extension means being disposed between the shorting contact and the interface when the header is inserted into the housing receptacle.
Claim 6
Dependent Claim
23 words
The electrical shorting contact of claim 4, wherein the beam and extension means are formed of a material which does not conduct electricity.
Claim 7
Dependent Claim
227 words
An electrical shorting system in a receptacle housing, an insertable header, the header being slidably and removably received in the receptacle housing, the receptacle housing having a female connector formed thereon, the header having a male pin formed thereon wherein the female connector electrically cooperates with the male pin when the header is inserted into the receptacle housing, a member having a "U" shaped form with a first leg, a second leg and a bight portion therebetween, the bight portion providing a resiliency between the legs, the first leg having an end thereon, the end being an electrical contact to engage an interface in the receptacle housing for shorting the system, the header having a beam formed thereon, the beam having an inclined portion formed thereon, said inclined portion contacting the first leg of the member when the header is inserted in the receptacle housing and deflecting the first leg of the member toward the second leg of the member, wherein the end of the first leg is removed from electrical contact with the interface after the female connector electrically engages the male pin on the header, and wherein, when the header is removed from the receptacle housing, the end of the leg of the member is resiliently urged into electrical contact with the interface before the female connector electrically disengages the male pin on the header.
Claim 8
Dependent Claim
227 words
An electrical shorting system in a receptacle housing, an insertable header, the header being slidably and removably received in the receptacle housing, the receptacle housing having a female connector formed thereon, the header having a male pin formed thereon wherein the female connector electrically cooperates with the male pin when the header is inserted into the receptacle housing, a member having a "U" shaped form with a first leg, a second leg and a bight portion therebetween, the bight portion providing a resiliency between the legs, the first leg having an end thereon, the end being an electrical contact to engage an interface in the receptacle housing for shorting the system, the header having a beam formed thereon, the beam having an inclined portion formed thereon, said inclined portion contacting the first leg of the member when the header is inserted in the receptacle housing and deflecting the first leg of the member toward the second leg of the member, wherein the end of the first leg is removed from electrical contact with the interface after the female connector electrically engages the male pin on the header, and wherein, when the header is removed from the receptacle housing, the end of the leg of the member is resiliently urged into electrical contact with the interface before the female connector electrically disengages the male pin on the header.
Claim 9
Dependent Claim
79 words
The electrical shorting system of claim 6, further comprising the beam having a first side and a second side, an extension means being formed on each respective side of the beam, wherein when the header is inserted into the receptacle housing, said extension means is disposed between the end of the first leg of the member and the interface, thereby assuring the absence of electrical contact between the end of the first leg of the member and the interface.
Claim 10
Dependent Claim
24 words
The electrical shorting system of claim 7, wherein the beam and the extension means are formed from a material which does not conduct electricity.
