Abstract
Abstract A connector housing assembly (2,4) having a first shunt contact (20) and circuit, and a second shunt contact (50) and circuit arranged in a first connector housing (8). A second connector housing (6) includes a contact cancelling part (58) for engagement with the first shunt contact (20) thereby opening the first circuit, and a fitting detecting contact (52) for engagement with the second shunt contact (50). The first shunt circuit is opened before the second shunt circuit is made.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
An electrical connector assembly comprising matable first and second connector housings: said first connector housing having a first shunt contact for maintaining a first shunt circuit when said connector housings are in an unmated state, and a second shunt contact for maintaining a second shunt circuit when said connector housings are in a mated state; said second connector housing including a shunt interface member for engaging and opening said first shunt contact in the mated state, and a fitting detecting contact for engagement with said second shunt contact when said connector housings are in the mated state; whereby, said first shunt circuit is opened before said second shunt circuit is made when said housings are moved from the unmated to the mated state.
Claim 2
Dependent Claim
123 words
An electrical connector assembly comprising matable first and second connector housings: said first connector housing having a first shunt contact for maintaining a first shunt circuit when said connector housings are in an unmated state, and a second shunt contact for maintaining a second shunt circuit when said connector housings are in a mated state; said second connector housing including a shunt interface member for engaging and opening said first shunt contact in the mated state, and a fitting detecting contact for engagement with said second shunt contact when said connector housings are in the mated state; whereby, said first shunt circuit is opened before said second shunt circuit is made when said housings are moved from the unmated to the mated state.
Claim 3
Dependent Claim
27 words
The electrical connector assembly of claim 1, wherein the first connector housing includes a double lock member having a cavity through which the first shunt contact passes.
Claim 4
Dependent Claim
46 words
The electrical connector assembly of claim 1, wherein the first connector housing includes a terminal receiving passageway with a wall having an aperture therein, said first shunt contact having a raised edge which projects through said aperture into said passageway for engagement with an electrical contact.
Claim 5
Dependent Claim
40 words
The electrical connector assembly of claim 1, wherein the first connector housing includes a fitting lever which engages the second shunt contact and is thereby resiliently biased for upward and downward cantilever action as said housings are mated and unmated.
Claim 6
Dependent Claim
40 words
The electrical connector assembly of claim 4, wherein the fitting lever includes a fitting step means for engagement with said second housing and for downward cantilever movement of the fitting step against the biasing force of the second shunt contact.
Claim 7
Dependent Claim
105 words
An electrical connector assembly having matable first and second connector housings, the second connector housing including a shunt interface member for cooperating with the first connector housing as the housings are urged toward the mated state, said first housing comprising: a first shunt contact for maintaining a first shunt circuit when said connector housings are in an unmated state, and a second shunt contact for maintaining a second shunt circuit when said connector housings are in a mated state; whereby, said first shunt circuit is opened before said second shunt circuit is made when said housings are moved from the unmated to the mated position.
Claim 8
Dependent Claim
105 words
An electrical connector assembly having matable first and second connector housings, the second connector housing including a shunt interface member for cooperating with the first connector housing as the housings are urged toward the mated state, said first housing comprising: a first shunt contact for maintaining a first shunt circuit when said connector housings are in an unmated state, and a second shunt contact for maintaining a second shunt circuit when said connector housings are in a mated state; whereby, said first shunt circuit is opened before said second shunt circuit is made when said housings are moved from the unmated to the mated position.
Claim 9
Dependent Claim
27 words
The electrical connector assembly of claim 6, wherein the first connector housing includes a double lock member having a cavity through which the first shunt contact passes.
Claim 10
Dependent Claim
46 words
The electrical connector assembly of claim 6, wherein the first connector housing includes a terminal receiving passageway with a wall having an aperture therein, said first shunt contact having a raised edge which projects through said aperture into said passageway for engagement with an electrical contact.
Claim 11
Dependent Claim
39 words
The electrical connector assembly of claim 6, wherein the connector housing includes a fitting lever which engages the second shunt contact and is thereby resiliently biased for upward and downward cantilever action as said housings are mated and unmated.
Claim 12
Dependent Claim
44 words
The electrical connector assembly of claim 9, wherein the fitting lever includes a fitting step means for pressing engagement with said second housing, and for downwardly directed cantilever movement of the fitting step against the upwardly directed biasing force of the second shunt contact.
