Connector including cam member operable for performing a fitting operation

Claim 2

A connector, comprising: first and second housing each adapted to receive a plurality of electrical terminals therein; a camming member at least partially circumscribing said housings and being engageable therewith, said camming member including at least one side wall which opposes a side wall of said first housing with a space therebetween, said camming member being moveable in a first direction with respect to said housings to attendantly move said housings toward and away from each other along a second direction substantially perpendicular to said first direction, said space increasing to a predetermined width when said camming member has moved said housings toward each other to a completely engaged position; and a detecting member insertable into said space only when the width of said space has reached said predetermined width, wherein said completely engaged position is detected by observing whether said detecting member can be inserted into said space.

Claim 3

A connector according to claim 1, wherein said detecting member is projected from a wall of an electrical connecting unit.

Claim 4

The connector of claim 1, wherein said camming member is substantially rectangular in shape, opposite side walls of said camming member, which are perpendicular to said at least one side wall, including a cam slot extending substantially diagonally with respect thereto, and wherein one of said housings includes a projection extending from opposite sides thereof and being individually engageable with said cam slots.

Claim 5

The connector of claim 3, wherein said camming member includes a transverse slot provided in said opposite side walls and extending in said first direction, and wherein the other of said housing includes a projection extending from opposite sides thereof which are individually engageable with said transverse slots.

Claim 6

The connector of claim 1, wherein said at least one side wall of said camming member includes a pair of fitted state confirming projections extending toward said housings for preventing insertion of said detecting member when said space has not reached said predetermined width.

Claim 7

A connector according to claim 5, wherein said camming member further includes: a lock arm interposed between said fitted state confirming projections and having an engagement projection, said engagement projection being engageable with said detecting member when both said housings are in said completely engaged position.

Claim 8

A connector, comprising: first and second housings each adapted to receive a plurality of electrical terminals therein: camming means for moving said housings toward and away from each other, said camming means including a camming member at least partially circumscribing said housings and being engageable therewith, said camming member includes at least one side wall which opposes a side all of said first housing with a space therebetween, said camming member being moveable in a first direction with respect to said housings to attendantly move said housing toward and away from each other along a second direction substantially perpendicular to said first direction, said space increasing to a predetermined width when said camming member has moved said housings toward each other to a completely engaged position; and a detecting member insertable into said space only when the width of said space has reached said predetermined width, wherein said completely engaged position is detected by observing whether said detecting member can be inserted into said space.

Claim 9

A connector, comprising: first and second housings each adapted to receive a plurality of electrical terminals therein: camming means for moving said housings toward and away from each other, said camming means including a camming member at least partially circumscribing said housings and being engageable therewith, said camming member includes at least one side wall which opposes a side all of said first housing with a space therebetween, said camming member being moveable in a first direction with respect to said housings to attendantly move said housing toward and away from each other along a second direction substantially perpendicular to said first direction, said space increasing to a predetermined width when said camming member has moved said housings toward each other to a completely engaged position; and a detecting member insertable into said space only when the width of said space has reached said predetermined width, wherein said completely engaged position is detected by observing whether said detecting member can be inserted into said space.
