Abstract: A connector comprises a plug, and a receptacle mounted on a substrate and having an opening into which the plug is inserted. The receptacle has a housing for holding a receptacle-side terminal part in an interior of a tubular shield cover that forms the opening. An engagement projection part provided to the plug engages with an engagement hole provided to a region of the shield cover of the receptacle that faces the substrate when the plug is inserted into the receptacle, and in a state in which the receptacle is mounted on the substrate, the region of the shield cover to which the engagement hole is provided is positioned away from the substrate by a set distance.

Abstract: A printed circuit board assembly includes a printed circuit board; a component adapted to be mounted on the printed circuit board, the component having a ground/earth terminal in at least an outer face thereof; and a shield case for surrounding the printed circuit board or covering the component. The shield case includes a contact part for contacting the ground/earth terminal of the component.

Abstract: A cable assembly includes a cable having a plurality of signal lines; a plug portion connectable to a connection target; a circuit board, a first end portion of the circuit board being provided with a plurality of connection portions that are respectively connectable by soldering to the signal lines of the cable, and a second end portion of the circuit board being connectable to the plug portion; and a holder for holding the circuit board. The holder is provided with a plurality of signal line guide grooves for positioning and fixing the signal lines with respect to the connection portions of the circuit board.

Abstract: A vibration sensor capable of preventing a diaphragm electrode from being damaged without lowering sensitivity as well as realizing a satisfactory assembling process. The vibration sensor includes a fixed electrode 1, and a diaphragm electrode 3 having a weight member 2 attached to a membrane surface facing away from the fixed electrode 1 and fixedly supported at peripheries thereof, the vibration sensor being capable of outputting variation of capacitance between the fixed electrode and the diaphragm electrode as vibration signals. The vibration sensor further includes projecting portions 2a formed on parts of an end portion of the weight member 2 to project along the direction of the membrane surface and spaced from the membrane surface of the diaphragm electrode 3, and a restricting member 4 for contacting the projecting portions 2a of the weight member 2 displaced along the direction of the membrane surface of the diaphragm electrode 3, thereby to restrict displacement of the weight member 2.

Abstract: A capacity detection type sensor element includes a rectangular vibrating plate, a flat back electrode which are provided opposedly with each other, and fixing portions which are provided adjoining to the vibrating plate, and has a predetermined length A of edge at a side adjoining to the vibrating plate. The back electrode is held by the fixing portions in a state that space is provided between the back electrode and the vibrating plate. Outer edges of the back electrode which are not held by the adjoining fixing portions, are straight lines and the straight lines define an octagonal shape as a whole.
