The cam member is rotatably mounted to the housing. The cam member comprises a caming surface adapted to contact a cam portion of a mating electrical connector. The cam member comprises a gear section with teeth engaging the teeth of the slide. The CPA member is movably connected to the housing. The CPA member is adapted to directly engage the cam member for preventing the cam member for rotating relative to the housing. ## Claims ### Claim 1 An electrical connector comprising: a housing; a slide slidably mounted to the housing, wherein the slide comprises a rack section with teeth, and wherein the slide is adapted to slide over a portion of a mating electrical connector when the electrical connector is connected to the mating electrical connector; a cam member rotatably mounted to the housing, wherein the cam member comprises a caming surface adapted to contact a cam portion of the mating electrical connector, and wherein the cam member comprises a gear section with teeth engaging the teeth of the slide; and a connector position assurance (CPA) member movably connected to the housing, wherein the CPA member is adapted to directly engage the cam member for preventing the cam member from rotating relative to the housing. ### Claim 2 (depends on 1) An electrical connector as in claim 1 wherein the cam member comprises a CPA slot adapted to receive a portion of the CPA member. ### Claim 3 (depends on 2) An electrical connector as in claim 2 wherein the cam member comprises a cam slot forming the caming surface, and wherein an entrance to the CPA slot is offset about 90 degrees from an entrance to the cam slot. ### Claim 4 (depends on 1) An electrical connector as in claim 1 wherein the slide comprises a main housing section having a general ring shape with a central channel with the housing slidably located therein. ### Claim 5 (depends on 4) An electrical connector as in claim 4 wherein the slide comprises: a first latch comprising a first deflectable cantilevered arm extending into the central channel in a first direction; and a second latch comprising a second deflectable cantilevered arm extending into the central channel in a second direction. ### Claim 6 (depends on 5) An electrical connector as in claim 5 wherein the cam member comprises a CPA slot adapted to receive a portion of the CPA member. ### Claim 7 (depends on 6) An electrical connector as in claim 6 wherein the cam member comprises a cam slot forming the caming surface, and wherein an entrance to the CPA slot is offset about 90 degrees from an entrance to the cam slot. ### Claim 8 (depends on 7) An electrical connector as in claim 7 wherein the CPA member is slidably mounted directly on the housing proximate a rear side of the cam member. ### Claim 9 (depends on 8) An electrical connector as in claim 8 further comprising electrical contacts mounted to the housing. ### Claim 10 (depends on 9) An electrical connector as in claim 9 wherein the cam member comprises a pin receiving slot, and wherein the pin receiving slot comprises an elongated straight entrance. ### Claim 11 An electrical connector comprising: a housing; a slide slidably mounted to the housing, wherein the slide comprises a rack section with teeth; a cam member rotatably mounted to the housing, wherein the cam member comprises a taming surface adapted to contact a cam portion of a mating electrical connector, and wherein the cam member comprises a gear section with teeth engaging the teeth of the slide; and a connector position assurance (CPA) member movably connected to the housing, wherein the CPA member is adapted to directly engage the cam member for preventing the cam member from rotating relative to the housing, wherein the CPA member is slidably mounted directly on the housing proximate a rear side of the cam member. ### Claim 12 An electrical connector slide member comprising: a main housing section having a general ring shape with a central channel adapted to receive a housing of an electrical connector therein; a rack section comprising teeth on the main section at the central channel arranged in a row as a series along a longitudinal length of the rack section; a first latch comprising a first deflectable cantilevered arm extending into the central channel in a first direction; wherein the first arm extends from a front end of a cantilevered section of a side wall of the main housing section and a second latch comprising a second deflectable cantilevered arm extending into the central channel in a second direction, wherein the second arm extends from a top wall or a bottom wall of the main housing generally perpendicular to the side wall. ### Claim 13 (depends on 12) An electrical connector slide member as in claim 12 wherein the general ring shape is a closed ring shape. ### Claim 14 (depends on 12) An electrical connector slide member as in claim 12 wherein the general ring shape has a general oval shape. ### Claim 15 (depends on 12) An electrical connector slide member as in claim 12 wherein a rear top side of the main housing section has a first recess adapted to receive a portion of a connector position assurance (CPA) member therein. ### Claim 16 (depends on 15) An electrical connector slide member as in claim 15 wherein a front bottom side of the main housing section has a second recess adapted to receive a portion of a mating electrical connector therein. ### Claim 17 (depends on 12) An electrical connector slide member as in claim 12 further comprising sliding interlock features extending into the central channel from the top wall of the main housing section, wherein the sliding interlock features comprise two general L shaped legs extending in opposite directions. ### Claim 18 (depends on 17) An electrical connector slide member as in claim 17 wherein one of the L shaped legs has the rack section thereon. ### Claim 19 (depends on 12) An electrical connector comprising: a housing; electrical contacts connected to the housing; a slide member as in claim 12 slidably mounted to the housing; a cam member rotatably mounted to the housing, wherein the cam member comprises a taming surface adapted to contact a cam portion of a mating electrical connector, and wherein the cam member comprises a gear section with teeth engaging the teeth of the slide member; and a connector position assurance (CPA) member movably connected to the housing, wherein the CPA member is adapted to directly engage the cam member for preventing the cam member for rotating relative to the housing. ### Claim 20 An electrical connector comprising: a housing adapted to receive a portion of a mating electrical connector; a slide movably mounted to the housing, wherein the slide comprises a section with teeth, and wherein the slide is adapted to be moved from a retracted position on the housing to an extended position on the housing around portion of the mating electrical connector; and a cam member rotatably mounted to the housing, wherein the cam member comprises a caming surface adapted to contact a cam portion of the mating electrical connector, wherein the cam member comprises a gear section with teeth engaging the teeth of the slide, and wherein the cam member comprises a connector position assurance (CPA) slot adapted to receive a portion of a CPA member in the CPA slot.
