Abstract: Provided is a method of manufacturing a sensor. The sensor has a casing having an opening portion, a clamp having a recessed part on its outer periphery and having one end inserted into the opening portion, and a sealing ring attached to the recessed part and disposed between the casing and the clamp. The method includes using a first divided mold to form a first component of the clamp, the first component including a main body portion and a first part located at one end side of the main body portion and forming a part of the recessed part. The first divided mold is divided so that a dividing surface intersects the main body portion and separates in an axial direction of the main body portion.

Abstract: The sensor adaptor includes a case body of which a front end is closed and a rear end is open, a cap body being engageable with the rear end of the case body, a seal member interposed between the case body and the cap body, and a fixing portion configured to fix the case body to the mounting portion. A part of the sensor is inserted into an accommodation space of the case body, and the remaining portion of the sensor is drawn out to the outside via an opening of the cap body. The seal member is disposed on a rear end side of the case body to surround the sensor. The seal member is brought into close contact with the case body and the sensor. Accordingly, a gap between the part of the sensor and the case body is sealed from an external space by the seal member.

Abstract: A sensor is provided with a cylindrical-shaped housing which has an opening formed at one end, an electronic component which is housed in the housing, a cylindrical-shaped clamp of which one end is inserted into the housing from the opening, and a sealing resin which seals the gap between the inner wall of the housing and the outer wall of the clamp. On the outer wall, the clamp has a rib which rises towards the inner wall of the housing. The rib includes an apex and a sloped surface which extends from the apex towards another end of the clamp and which intersects the outer wall of the clamp. The sealing resin, which exudes from between the inner wall of the housing and the apex and which is positioned on the sloped surface, has a recess resulting from surface tension.

Abstract: To provide an electronic apparatus which enables manufacturing costs to be reduced and a range of selection of materials for resin components to be widened. An electronic apparatus (1A) includes a case (10), a cable (30) drawn out from the case (10), a bonding intermediating member (40) that is made of a resin and joined to the cable (30), a cylindrical clamp (50) holding the cable (30), and a sealing resin part (60) filling an internal space defined by the case (10) and the clamp (50). The cable (30) has a core wire (31) and a sheath (33) that is made of a resin covering the core wire (31) and the core wire (31) is exposed not to be covered by the sheath (33) at an end of the cable (30). The bonding intermediating member (40) has a cylindrical base (41) covering an outer circumferential face of the sheath (33) and an extension part (42) extending from the base (41) and bonding to the sealing resin part (60). The bonding intermediating part (40) is fixed to the cable (30) by welding the base (41) onto the sheath (33).

Abstract: A proximity sensor in which generation of voids in a resin sealing portion sealing an inside of a housing can be suppressed and thus a yield is improved. The proximity sensor includes a housing, a detection coil, a circuit board and a resin sealing portion. The circuit board is accommodated in the housing to partition an internal space of the housing, and the resin sealing portion covers at least a part of the circuit board by filling the internal space of the housing and thus seals a covered portion of the circuit board. A resin injection port configured to inject a liquid resin forming the resin sealing portion by curing the liquid resin is provided in the housing, and a cutout portion having a notch shape or an opening shape is provided in the circuit board to include at least a part of a portion facing the resin injection port.
