摘要： PROBLEM TO BE SOLVED: To prevent the leakage of a laser beam to the outside or the infiltration of dust or the like by providing a shutter for opening/closing the light emitting part of a light transmission means fitted into a housing with the motion of a movable part which is moved in accordance with the motion of the light transmission means. SOLUTION: The movable part 40 is moved to the inside of a connector housing 20, that is, to the back side against the elastic force of a movable spring 60 in accordance with the degree of the fitting of a plug housing 80 in the connector housing 20. With the movement of the movable part 40, a holding pin 54 fixed at the movable part 40 is also moved to the back side of the housing 20. The shutter 52 fixed with the pin 54 partially abuts on (34) a sleeve end face 32, so that the shutter 52 is retreated toward the inner wall side on the movable part 40 side against the elastic force of a pressing spring 56 with the abutting part 34 as fulcrum with the movement of the pin 54. Thus, the shutter 52 is automatically opened interlocking with the fitting of the housing 80.

摘要： PROBLEM TO BE SOLVED: To select relatively freely lock releasing force and the slide stroke, by forming an operating surface between a slide part and a lock lever so that operating part between the slide part and the lock level differs. SOLUTION: In the beginning of slide stroke of a slide cover 40, inward elastic deviation of a lock lever 20 is performed using as an action point a contacting part of a first deviation operating inclined-face 42 with a cam operating inclined-face 23. Because the action point relatively far from a fulcrum 22, releasing force to be added to slide the slide cover 41 may be relatively smaller. In the subsequent stage, the inward elastic deviation of the lock lever 20 is performed using as the action point a connecting part of a second deviation operating inclined-face 43 with the cam operating inclined-face 23, the action point positions near the fulcrum 22, and lock release is done at one stroke without enlarging slide stroke.

摘要： PROBLEM TO BE SOLVED: To form a plug-in structure on respective connector elements by arranging lock mechanisms in the respective connector elements. SOLUTION: Connector elements are respectively arranged on the plug side and the jack side of a connector. A plug connector element is arranged in a condition of being incorporated into plug connectors 1, and is arranged in a jack connector 3 in a mountable-demountable condition. The plug connectors 1 are engaged with each other by fitting a front end part of a frame 140 of the plug connector element to a PA adapter housing 700 of the jack connector 3. At this time, the front end part of the frame 140 of the plug connector element is inserted into a through hole of the PA adapter housing 700, and a side surface engaging projection part 147 of the frame 140 is fitted in a snap to an engaging opening part 701 of the PA adapter housing 700.

摘要： PURPOSE:To prevent adhesion of dust, etc., from the atmosphere outside a connector on the end face of an optical fiber of an optical terminal at the time of storing the connector by providing the cap with a shielding part which shields the optical fiber end face of the optical terminal against the space in a connector shell part where electric terminals exist when the cap is mounted at the front end of the connector shell part. CONSTITUTION:The end face of a projecting part 42 is pressed to the end face of the optical fiber of the optical terminal 33 arranged in the space 32 in the connector shell part 31 when the opto-electric composite connector 30 is going to be stored and the projecting part is mounted at the front end of the connector shell part 31 at the time of not using the connector. Then, the end face of the projecting part 42 of the cap 40 mounted at the front end of the connector shell part 31 is held pressed to the end face of the optical fiber of the optical terminal 33 and the end face of the optical fiber is held shielded from the electric terminals 34 arranged in the space 32 within the connector shell part 31 when the opto-electric composite connector 30 is going to be stored at the time of not using the connector.

摘要： PURPOSE: To allow the replacement and repair of a shutter part, and the use as it is removed by providing a plug shutter for automatically opening each terminal hole at fitting on a connector consisting of a plug and a jack in such a manner as to be attachable and detachable. CONSTITUTION: A plug 100 and a jack 200 are mutually fitted to connect a plug terminal 1 to a jack terminal (not shown). The above connector has shutters 130, 230 for closing each plug terminal hole 131 (a jack terminal hole is root shown) at non-fitting by a plug shutter 140 and a jack shutter 230. The plug shutter 140 is installed to a plug internal shell 130 in such a manner as to be removable, and automatically rotated by the fitting operation of the connector to conform the plug shutter hole 141 to the plug terminal hole 131, so that a plug terminal 1 can be extended through and connected.

摘要： PURPOSE:To prevent a danger due to wrong operation by moving a jack shutter, thus putting together a jack terminal hole and a jack shutter hole and so making contact with a jack terminal by penetrating the holes. CONSTITUTION:A jack guide 213 of a jack 286 is inserted a plug guide groove 113 of a plug 100. In this case, a plug guide 114 is inserted in tip of a shutter guide 233, and a shutter guide 232 is inserted into a shutter guide groove 142. Then, when a guide 114 goes through a taper portion 233A of a groove 233 and thus is positioned in a straight portion, a jack terminal hole 221 of a block 223 within the jack and a jack shutter hole 231 of a jack shutter 238 are mutually communicated. In this case, a plug terminal hole 131 of an in-plug shell 130 and a plug shutter hole 141 of a plug shutter 140 are also mutually communicated. Accordingly, a contact or a connection to a corresponding hole of the block 223 is attained through a hole 231 corresponding to a hole 230.

摘要： PURPOSE: To substantially prevent the adverse influence of rotational mispositioning of housings from each other by specifying the shape of the spacing in the rotating direction between the inner peripheral wall of the housing and the outer peripheral wall of an optical fiber ferrule. CONSTITUTION: Respective key members 34 of a stopper part 30 are engaged with consisting key grooves 44 of the flange part 43 of the optical fiber ferrule 40, by which the rotation of the optical fiber ferrule 40 around its axial center is regulated. The spacings in the rotation direction between the key grooves 44 and key members 34 fitted to each other are set extremely small in the state before coupling to the other optical connector and the rotational positions are strictly regulated. The spacings in the rotation direction between the key grooves 44 and key members 34 fitted to each other are, however, set relatively large in the state after coupling to the other optical connector. Then, a relatively large floating quantity is obtd. after the coupling to the other optical connector.

摘要： PROBLEM TO BE SOLVED: To provide a connector which is easily locked but difficult to be unlocked. SOLUTION: In a bayonet lock connector, the bayonet lock is achieved by rotating a plug 200 towards a receptacle (120), and after the bayonet lock is completed through this rotation work, a double lock structure is ensured by providing another lock mechanism, so as to automatically lock the plug 200 and the receptacle (120). On the other hard, when this double lock structure is released, a lock structure is ensured so that the bayonet lock cannot released, as long as the latter lock is not released.
