Abstract:
A sensor device comprising:a housing (11) capable of being secured to a fixed support (10);an IC module (12) having a detection portion (14), the module being housed and fixed in the housing (11) so that the detection portion (14) is disposed at the top end of the housing (11); anda cord (13) in which a plurality of signal lines (18,18 . . . ) are covered with an insulative covering material (19), one end of the covering material (19) is joined to the rear end of the housing (11), and the portions of the signal lines (18,18 . . . ) extended from one end of the insulative covering material (19) are electrically connected with the IC module (12) in the housing (11), whereinthe housing (11) is composed of:an inner core (16) which is molded from a synthetic resin so as to cover one end of the insulative covering material (19), the signal lines (18,18 . . . ) extended from one end of the insulative covering material (19), the IC module (12) and connection portions between each of the signal lines (18,18 . . . ) and the IC module (12) andan outer shell (17) made of a synthetic resin and molded to the outer periphery of the inner core (16) so as to cover the inner core (16),wherein the inner core (16) has, at the outer periphery thereof, an outer circumference defining a substantially polygonal shape in cross section, wherein engaging protrusions are disposed on each face of said substantially polygonal shape, said engaging protrusions (25-28) adapted for engagement with and abutting on positioning recesses (30) disposed to a mold device (43) for molding the outer shell (17) in order to position the inner core (16) relative to the outer shell (17).
