A substance detection system ( 1 A) includes a substance sensor ( 10 ), a distance sensor ( 11 ), and an information processor ( 20 ). The substance sensor ( 10 ) detects a substance ( 3 ) emitted from a generation source ( 2 ). The distance sensor ( 11 ) detects distance (L) between the generation source ( 2 ) and the substance sensor ( 10 ). The information processor ( 20 ) includes a determiner ( 21 ). The determiner ( 21 ) determines whether or not the distance (L) detected by the distance sensor ( 11 ) falls within a range from (L 1 ) to (L 2 ) where a detection result by the substance sensor ( 10 ) is determined to be valid.

An electrical connector pair ( 1 ) includes: receptacle connectors ( 4 ) mounted on a mounting face ( 6 a) of a board ( 6 ) and arrayed in a Y-axis direction along the mounting face ( 6 a); and plug connectors ( 5 ) capable of mating with the receptacle connectors ( 4 ) on a one-to-one basis. The plug connectors ( 5 ) each include a projection ( 24 b) projecting in the Y-axis direction in such a way as to partially overlap with an adjacent plug connector ( 5 ) of the plug connectors ( 5 ) when viewed from a Z-axis direction in which the receptacle connectors ( 4 ) mate with the plug connectors ( 5 ).

Electromagnetic shielding about both of electric connectors, which are in a mutually mated state, can be sufficiently carried out by a simple configuration. Shield wall portions composed of electrically-conductive members opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in multipolar shapes are provided; electromagnetic shielding functions with respect to the contact connecting portions in the respective electric connectors are obtained well by the respective shield wall portions; and, when both of the electric connectors are mated with each other, the shield wall portions are configured to be in an inner/outer double disposition relation in which they are opposed to each other and efficiently block the gaps between the shield wall portions and wiring boards so that sufficient EMI measures can be expected.

A cable assembly includes: a pair of transmission conductors; a dielectric covering the pair of transmission conductors; an outer conductor covering a surface of the dielectric; and a sheath covering the outer conductor, wherein the cable includes a first region, a second region, and a third region sequentially aligned from a tip of the cable, wherein in the first region, the pair of transmission conductors are exposed, wherein the second region includes: a connecting portion in which the outer conductor is exposed; and a non-connecting portion covered by the sheath, wherein in the third region, the outer conductor is covered with the sheath entirely over a circumference of the cable, wherein the connector includes: a pair of conductive contacts electrically connected to the pair of transmission conductors; and a conductive shell surrounding the pair of conductive contacts and electrically connected to the connecting portion.

In a receptacle connector, a conductive contact ( 11 ) is a linear member uniform in width in a thickness direction and extending in a plane orthogonal to the thickness direction while curving, and includes: a contacting portion ( 11 a ) to contact a plug contact ( 21 ) at a first face ( 30 ) containing a line extending in the thickness direction; a substrate connecting portion ( 11 b ) to connect to a signal electrode ( 2 b ) on a substrate ( 2 ) at a second face ( 31 ) containing a line extending in the thickness direction; and a turnback portion ( 11 c ) connected to the contacting portion ( 11 a ) and the substrate connecting portion ( 11 b ) respectively at first and second ends ( 32, 33 ) in a longitudinal direction with a turned-back shape between the first end ( 32 ) and the second end ( 33 ) in the orthogonal plane. The top ( 34 ) of the turnback portion ( 11 c ) is pressed into and engaged with the insulation housing.

A connector device comprising a first connector and a second connector. The first connector comprises: a plurality of conductive first contacts; an insulating first contact holding portion holding the plurality of first contacts; a conductive partition wall partitioning the first contact holding portion into a first grouping area that holds two or more first contacts and a first individual area that holds one first contact; and a conductive first surrounding wall disposed around an outer periphery of the first individual area so that the first surrounding wall and the partition wall at least partially surround the first individual area. The second connector comprises: a plurality of conductive second contacts; and a conductive second surrounding wall. When the first connector and the second connector are fitted to each other, the second surrounding wall is disposed inside or outside the first surrounding wall around the outer periphery of the first individual area.

A connector includes a housing. The housing includes a terminal placement space, a first insertion space, a first guide, a retraction area, and a second guide. The first guide is placed frontward of the first insertion space on a positive X direction side in an insertion direction in which the first board is inserted and guides insertion of the first board in an inclination direction inclined relative to an X-axis direction. The retraction area is placed continuously with the first guide and retracts a leading edge on a negative X direction side of the first board from the terminal. The second guide is placed continuously with the retraction area, decreases inclination of the first board inserted in the inclination direction, and guides the first board to come into contact with the terminal.

The conductive member ( 3 ) is arranged in such a manner as to surround a facing area facing the second connector ( 4 ) to be fitted to the first connector ( 2 ) within a mounting surface ( 5 a ) of the board ( 5 ) along the mounting surface ( 5 a ) in conjunction with the receptacle shell ( 22 ). The second connector ( 4 ) includes a conductive first shell ( 43 ) arranged in such a manner as to, when being fitted to the first connector ( 2 ), come into contact with the receptacle shell ( 22 ) and the conductive member ( 3 ) and cover the receptacle terminals ( 21 ) in conjunction with the receptacle shell ( 22 ) and the conductive member ( 3 ).
