Abstract: An optical connector plug with a shutter to be fitted to an optical connector adapter includes: a plug frame configured to hold a ferrule; a square cylindrical front housing including a shutter that opens and closes with a movement of the ferrule; a locking housing fixedly and integrally connected to the plug frame and configured to be fitted into and be locked with the optical connector adapter; and a spring that biases the front housing forward. The plug frame is moved forward by a rearward movement of the front housing, a front opening edge portion of the plug frame expands a shutter into a straight shape, and the shutter includes slits straddling over a boundary between a flat portion and a curved portion when light is blocked, and a protrusion formed by a center portion being deformed by the expanded shutter when being fitted is cancelled.

Abstract: An optical connector plug includes a front housing, configured to hold a ferrule and to be fitted with a fitting portion of a coupling counterpart member, and a rear housing, mounted to the front housing to be allowed to slide toward front and rear directions at a rear side of the front housing. The front housing includes a latching piece with elasticity. The latching piece includes a locking portion, engageable with an engaging portion for fitting of the coupling counterpart member, and a releasing portion, configured to release the locking portion from an engaging state with the engaging portion. The rear housing includes a releasing lever. The releasing lever includes a hook portion, formed at a front part and configured to engage with the releasing portion at a time of retreat of the rear housing, so as to activate a release, and a knob portion for retreat.

Abstract: When a moving member moves to a fixing position, a fixing member moves to a second fixing position, a blade of the fixing member cuts into a protection layer of a cord, and thereby the cord is fixed. When the moving member moves to a releasing position, the fixing member moves to a second releasing position, the blade leaves the protection layer, and thereby the cord is released.

Abstract: Disclosed a memory card connector including a case body having a memory card storage portion which allows insertion of either a memory card having single row of signal pad portions and a memory card having front and rear rows of the pad portions, the case body having rear-row signal contacts coming into abutment with the rear-row signal pad portions of the memory card and contacts that establish electric contact by coming into abutment with the single row of signal pad portions or the front-row signal pad portions. Each the rear-row signal contact has two contact ends to abut only with the case portion of the card when the card having single row signal pad portions is stored in the storage portion, and to abut only with the rear-row signal pad portion of the card when the card having the two rows of pad portions is stored in the storage portion.

Abstract: An optical device board 2 is set to be a printed circuit board in which an optical device 6 is bonded into a predetermined position of a printed wiring board 5. The optical device board 2 is bonded to a base board 3 provided with a plurality of wiring terminals 7. A lens barrel 4 is bonded to the optical device board 2. The optical device 6 is bonded into a position calculated from an actual measured dimension of the printed wiring board 5, and the calculated position is held and positioning is carried out in such a manner that a central axis of the lens barrel 4 is coincident with the calculated position when the lens barrel 4 is to be bonded to the optical device board 2.

Abstract: To prevent an inflow of resin at the time of integral molding and prevent the outer shape from upsizing, there is provided a cable connector including a connector body formed of an insulating material and formed with a plurality of terminal through holes; connecting terminals fitted into the terminal through holes; a cable including a plurality of leads having end portions that are crimped to base portions of the connecting terminals respectively; and a synthetic resin bushing configured to couple the connector body, a tip end portion of the cable including the leads exposed and diverged therefrom integrally by molding. Stoppers are disposed between end portions of the leads and the connecting terminals and inside the connector body and prevent intrusion of synthetic resin as the bushing material so as not to flow from ends of the leads toward ends of the connecting terminals when coupling by molding.

Abstract: An optical connector plug includes an approximately square cylindrical rear cover of an insulating member fitted over an outer surface of a stop ring, and a cylindrical front cover which is urged frontward by an elastic member and is slidable back and forth at an outer surface of a plug frame. The front cover has a flexible plate-like shutter on an inner wall, which blocks the tip of a ferrule. The shutter has an upright curved portion formed by curving a tip side in an arc shape. When the front cover moves backward, the curved portion of the shutter is pressed against a tip of the plug frame to become flat and is pressed against the inner wall of the front cover to be retained in a plate form, thereby releasing a light-shielding state of the optical fiber.

Abstract: An electrical connector is offered which has a crimp contact connected with a connector cable, the crimp contact being held in position to a connector housing without rattling. The crimp contact has sidewall surfaces of U-shaped cross section. The sidewall surfaces are located on opposite sides. The sidewall surfaces have outwardly facing engagement protrusions. The connector housing has a connector body and a disengagement-preventing cover for closing a top portion of the connector body to prevent the crimp contact from coming off upward after the crimp contact has been mounted in the connector body. The connector body has engagement portions in which the protrusions of the crimp contact are inserted and received perpendicularly to the longitudinal direction of the connector cable. The protrusions are engaged in the engagement portions. The disengagement-preventing cover is mounted to the connector body via a hinge such that the cover can be opened and closed.
