Abstract
Abstract A shunted connector assembly (14) wherein the electrical connector (12) has a housing (22) with spaced contacts (18), each having an exposed contact portion along an open portion of a side wall (30) of the housing. A shell member (64) is mounted to the connector housing and a shunt contact support housing (66) is slidably mounted to the shell member. The shunt contact support housing is movable generally linearly between first and second positions. When the shunt contact support housing is in the first position, shunt contacts (68, 70) secured therein engage pairs of spaced contacts (18) of the connector. When the shunt contact support housing is in the second position, the shunt contacts are electrically isolated from the connector contacts. A spring (72) biases the shunt contact support housing toward its first position so that when the connector is disengaged from a mating receptacle connector (36), the shunt contact support housing is automatically moved to the first position wherein connector contact pairs are electrically commoned. When the electrical connector is mated with a receptacle connector, the shunt contact support housing comes into interfering engagement with structure (58) surrounding the recess (176) of the receptacle connector so that the shunt contact support housing is moved to the second position. During movement of the shunt contact support housing from its first position toward its second position, it is lifted away from the electrical connector so that the shunt contacts do not rub against the connector.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
147 words
A shunt assembly for shorting electrical contacts of an electrical connector comprising: an insulative contact support member on an electrical connector, an electrical shunt contact supported on the support member, a shell member receiving the connector and the support member, a spring biasing the support member toward a first position alongside a mating end of the connector with the shunt contact in engagement with selected electrical contacts on the connector, the support member being urged to a second position by movement of the mating end into engagement with another, mating electrical connector, with the shunt contact being disengaged from the selected electrical contacts, and at least one cam surface on the support member engaging the connector during said movement of the support member, said cam surface biasing the support member outward relative to the connector to separate the shunt contact from the connector without frictional engagement therebetween.
Claim 2
Dependent Claim
147 words
A shunt assembly for shorting electrical contacts of an electrical connector comprising: an insulative contact support member on an electrical connector, an electrical shunt contact supported on the support member, a shell member receiving the connector and the support member, a spring biasing the support member toward a first position alongside a mating end of the connector with the shunt contact in engagement with selected electrical contacts on the connector, the support member being urged to a second position by movement of the mating end into engagement with another, mating electrical connector, with the shunt contact being disengaged from the selected electrical contacts, and at least one cam surface on the support member engaging the connector during said movement of the support member, said cam surface biasing the support member outward relative to the connector to separate the shunt contact from the connector without frictional engagement therebetween.
Claim 3
Dependent Claim
26 words
A shunt assembly as recited in claim 1, and further comprising: a second spring on the shell member biasing the shunt contact toward the selected contacts.
Claim 4
Dependent Claim
24 words
A shunt assembly as recited in claim 1 wherein, the cam surface comprises a projecting surface on the support member beside the shunt contact.
Claim 5
Dependent Claim
28 words
A shunt assembly as recited in claim 1 and further comprising: a second spring engaged against the support member to bias the shunt contact toward the selected contacts.
Claim 6
Dependent Claim
26 words
A shunt assembly as recited in claim 1 and further comprising: a second spring on the shunt assembly biasing the shunt contact toward the selected contacts.
Claim 7
Dependent Claim

Dependent Claim
119 words
A shunt assembly for shorting electrical contacts of an electrical connector comprising: an insulative contact support member on an electrical connector, an electrical shunt contact supported on the support member, a shell member receiving the connector and the support member, a spring biasing the support member toward a first position alongside a mating end of the connector with the shunt contact in engagement with selected electrical contacts on the connector, the support member being urged to a second position by movement of the mating end into engagement with another, mating electrical connector, with the shunt contact being disengaged from the selected electrical contacts, and a second spring on the shell member biasing the shunt contact toward the selected contacts.
Claim 10
Dependent Claim
119 words
A shunt assembly for shorting electrical contacts of an electrical connector comprising: an insulative contact support member on an electrical connector, an electrical shunt contact supported on the support member, a shell member receiving the connector and the support member, a spring biasing the support member toward a first position alongside a mating end of the connector with the shunt contact in engagement with selected electrical contacts on the connector, the support member being urged to a second position by movement of the mating end into engagement with another, mating electrical connector, with the shunt contact being disengaged from the selected electrical contacts, and a second spring on the shell member biasing the shunt contact toward the selected contacts.
Claim 11
Dependent Claim
29 words
