Abstract
Abstract A shorting connector for engaging a switch. A connector housing encloses two spaced apart contacts that form part of a circuit controlled by a switch. In the event that the switch is separated from the connector a torsion spring shorted element moves within the connector housing and bridges the spaced apart contacts to maintain a closed circuit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
Apparatus comprising: (a) a housing having spaced side walls that define a housing interior for enclosing metal contacts in spaced apart relation and further defining a passageway leading to the housing interior to accommodate passage of signal carrying conductors coupled to the spaced apart metal contacts, said housing defining interior ribs that separate said two metal contacts and define a slot in said housing interior; (b) an actuator movably supported in said slot for engagement with a mating connector that holds the actuator in a recessed position in the housing when the mating connector is brought into engaging relationship to the housing, said actuator having a post thereon; and (c) a torsion spring shorting wire carried by the actuator and including a central loop embracingly engaging the post mounted on the actuator and having elongated contact portions, said elongated contact portions normally engaging the two metal contacts to short said contacts and being movable out of engagement with said contacts by said interior ribs when the actuator moves said shorting wire into the slot in response to contact by the mating connector said shorting wire biasing the actuator to move the elongated contact portions back into engagement with the two metal contacts if the mating connector becomes disengaged from the housing.

Apparatus comprising: (a) a housing having spaced side walls that define a housing interior for enclosing metal contacts in spaced apart relation and further defining a passageway leading to the housing interior to accommodate passage of signal carrying conductors coupled to the spaced apart metal contacts, said housing defining interior ribs that separate said two metal contacts and define a slot in said housing interior; (b) an actuator movably supported in said slot for engagement with a mating connector that holds the actuator in a recessed position in the housing when the mating connector is brought into engaging relationship to the housing, said actuator having a post thereon; and (c) a torsion spring shorting wire carried by the actuator and including a central loop embracingly engaging the post mounted on the actuator and having elongated contact portions, said elongated contact portions normally engaging the two metal contacts to short said contacts and being movable out of engagement with said contacts by said interior ribs when the actuator moves said shorting wire into the slot in response to contact by the mating connector said shorting wire biasing the actuator to move the elongated contact portions back into engagement with the two metal contacts if the mating connector becomes disengaged from the housing.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein a portion of the actuator which engages the mating connector is not enclosed by the housing.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1 wherein the mating connector includes a protuberance for contacting the actuator when the mating connector is brought into engaging relationship to the housing.
Claim 5
Dependent Claim
179 words
A shorting connector comprising: (a) a housing enclosing two spaced apart metal contacts and having an input end for receiving a mating connector, said housing defining slot with a slot edge facing the input end of the housing; (b) an actuator movably supported in the slot and having a contact portion for engagement with the mating connector for movement of the actuator within the slot from a first position in the housing to a second position in the housing proximate to the first; (c) a post fixed on the actuator; and (d) an electrically conductive torsion spring having a loop embracing the post and a pair of biasing arms engaging the slot edge for biasing the actuator toward the first position and away from the second position, said torsion spring constructed and arranged to electrically couple the first and second contacts when the actuator is in the first position and to be deflected away from the first and second contacts as the actuator moves toward the second position due to engagement between the shorting connector and the mating connector.
Claim 6
Dependent Claim
179 words
A shorting connector comprising: (a) a housing enclosing two spaced apart metal contacts and having an input end for receiving a mating connector, said housing defining slot with a slot edge facing the input end of the housing; (b) an actuator movably supported in the slot and having a contact portion for engagement with the mating connector for movement of the actuator within the slot from a first position in the housing to a second position in the housing proximate to the first; (c) a post fixed on the actuator; and (d) an electrically conductive torsion spring having a loop embracing the post and a pair of biasing arms engaging the slot edge for biasing the actuator toward the first position and away from the second position, said torsion spring constructed and arranged to electrically couple the first and second contacts when the actuator is in the first position and to be deflected away from the first and second contacts as the actuator moves toward the second position due to engagement between the shorting connector and the mating connector.
Claim 7
Dependent Claim
40 words
A shorting connector according to claim 4 including signal-carrying conductors and wherein the housing defines first and second passageways external to the slot to route the signal-carrying conductors into the housing for electrical engagement with the first and second contacts.
Claim 8
Dependent Claim
40 words
A shorting connector according to claim 4 wherein the mating connector has a protuberance for engagement with the contact portion of the actuator for movement of the actuator toward the second position as the mating and shorting connectors are connected.
Claim 9
Dependent Claim
27 words
A shorting connector according to claim 4 wherein the contact portion extends outside the housing at the input end when the actuator is in the first position.
