摘要:
An optical connector to be connected to an optical plug holding optical fibers includes: a light-emitting element; a light-receiving element; and sleeves that optically connect the light-emitting element and the light-receiving element to optical fibers of the optical plug, respectively, in which a transmission sleeve and a reception sleeve are connected to each other via a link section to form a sleeve unit. The sleeve unit is secured by press-fitting the link section into a connector body. A stress caused by the press fitting is not exerted to the transmission sleeve and the reception sleeve, so that the optical functions (optical properties) of the sleeves can be prevented from being compromised by the stress.

An EL-illuminated switch which restrains the deterioration of an EL element resulting from outside pressure without causing unevenness of illumination, including an EL sheet, a rubber sheet, a dome switch, and a substrate. In the EL sheet, a luminescent part is formed at a position directly under a key top. The size of the luminescent part is smaller than the key top. A transparent electrode is disposed on the front surface side of the luminescent part, and a back surface electrode is disposed on the rear surface side. The transparent electrode is larger than the luminescent part. The back surface electrode includes an electrode principal part that is in contact with the back surface of the luminescent part and isolated from the lower sheet.

摘要:
An optical fiber connector component having a cylindrical light guide member (32) made of a transparent and elastic material, and a pipe (31) for housing the light guide member in the interior, wherein end surfaces (301) and (302) for connecting the light guide member with optical fibers are either convex or concave surfaces, and the distal end of the pipe protrudes past the connecting surfaces in the axial direction of the pipe. The radii of curvature of the connecting end surfaces of the light guide member differ from the radii of curvature of the distal end surfaces of the optical fibers. Therefore, when the distal ends of the optical fibers are inserted through the pipe and pressed against the connecting end surfaces of the light guide member, the connecting end surfaces deform, causing the contact areas to expand outward from the center, and air between the contact surfaces to be expelled.

An object of the invention is to minimize the accommodating space for the shutter of inward opening type. The shutter opening inward in accordance with the insertion of the plug is provided near the inlet of the plug inserting hole of the case. A shutter biasing spring holding the shutter in the closed position is a torsion coil spring including a pair of arms projecting in two directions from the coil part. The shutter biasing spring is arranged so that the coil part faces towards the hole back side between the back surface of the shutter and the inner wall surface of the case. When the shutter opens and lies along the inner wall surface, both arms are sandwiched between the shutter and the inner wall surface of the case, and the coil part are positioned outside between the shutter and the inner wall surface of the case.

摘要:
An optical connector with a shutter is provided which has functions of, when a plug (P) is not inserted, preventing dust from entering through an insertion and extraction port (12), and preventing light from leaking through the insertion and extraction port (12). In the invention, a shutter (5) is placed in an insertion space (13) of the body (1) in which an optical device (2) is disposed, and the shutter (5) is elastically urged in a closing direction. The shutter (5) is attached to a support shaft (4) which is placed in the vacant space (15) on a lateral side of the insertion and extraction port (12). When the plug (P) is not inserted, the shutter (5) closes the insertion and extraction port (12) to prevent ingress of dust and light leakage from occurring. The axial direction of the support shaft (4) coincides with the thickness direction of the body, whereby the height of the optical connector with a shutter can be reduced.
