摘要： PURPOSE:To largely reduce a crosstalk by separating signal passages formed of adjacent circuits of a matrix printed board to passages separated by connectors. CONSTITUTION:A connector 2 for containing circuits X1, X2,..., arranged in parallel with an X direction is mounted for connecting line side cables on a left region, and connectors 3, 4 for containing circuits Y1, Y2,..., arranged in parallel with a Y direction are mounted for connecting cables in a station side. The upper connector 3 has terminals corresponding to odd number circuits Y1, Y3, Y5,..., and the lower connector 4 has terminals corresponding to even number circuits Y2, Y4, Y6,.... Signals passing adjacent circuits Y1, Y2 or Y3, Y4 in a printed board 1 are separated by the connectors 3, 4 and passed through the separate passages. Thus, an opportunity of generating a crosstalk is reduced to improve the quality of a channel.

摘要： PURPOSE:To prevent a decrease in the reflected light of a laser near the boundary between a tracking pattern and a resist by plating the Ni plating applied on the surface of the copper foil of a copper laminated sheet with Au and coating the surface of the Au plating exclusive of the tracking pattern part with the resist. CONSTITUTION:The Ni plating 10 is applied by panel plating on the surface of the copper foil 6a of the copper laminated sheet 6. The Au plating 11 is applied by panel plating on this Ni plating 10 to form the flat plating. The Au plating 11 exclusive of the tracking pattern 1 is coated with the resist 2 of a non-reflector. The boundary line with the resist 2 is also formed with the tracking pattern 1 of the flat Au plating 11. The decrease in the reflected light of the laser near the boundary between the tracking pattern 1 and the resist 2 is thus prevented and the position of a differential point position detector is exactly detected.

摘要： PURPOSE:To eliminate a cable support and to reduce mounting area of a frame by placing the bundle of link wiring cables in an upper space of am MDF frame. CONSTITUTION:An MDF 1 has a printed board mounting frame 10 in which many printed boards 2 are divided into a plurality of groups to be arranged and mounted, and a control frame 12 for placing a controller 11 provided at its one end. The bundle of cables 5 bundled in predetermined shape and size is contained in the upper space of the frame 10. Cable groups 5a, 5b branched from the bundle are so disposed as to be vertically suspended from the front surface side of the board 1 mounted in the frame 10, and formed as a whole in a reedlike flow. Connectors are mounted at the ends of the cables, and connected to connectors of the boards 2 at the time of link wiring work.

摘要： PURPOSE:To make a connector small-sized and improve ease of connection by making both front and back housings afloat in a body relative to a back board and providing both the front housing and a PWB connector with a lock mechanism consisting of projection an groove as a body. CONSTITUTION:A PWB connector 15 is connected to a BWB connector 1 by inserting an opening fitting part 16a of the connector 15 into a front housing 2 of the connector 1. Connecting a sleeve-like screw 8 via the front housing and a back board 4 to a guide pin 6 on which a male thread 7 is formed for a back housing 3, the front housing and the back housing are made in a body afloat relative to the back board 4. Further, forming a cantilever 9 on the side of the front housing 2, a hole 11 of an appropriate shape is formed near the front end of the cantilever 9. Forming further a projection 19 of an appropriate shape at a position corresponding to the hole 11 so that the hook can be hooked to the projection 19 at the time of fitting, a lock mechanism is formed.

摘要： PURPOSE:To permit formation of a plastic cylindrical member and to improve economy by forming one end of an elastic sleeve as an aperture having the shape increased in the bore gradually toward the outside so as to provide a function to guide the other ferrule when said ferrule is fitted into the aperture. CONSTITUTION:The ferrule 8 inserted into a plug 5A from one end thereof is fixed to the elastic sleeve 9A made of a metal. The aperture 25 provided with the bore increased gradually toward the outside is formed to the other end of the elastic sleeve 9A. The other ferrule is guided by the aperture 25 by which said ferrule is adjusted in position and fitted when the ferrule is inserted into the sleeve 9A at the time of connecting the optical connector. Since there is no need for the cylindrical member 10A housing the sleeve 9A to deal with wear at the time of positioning, the use of the plastic to said member is permitted. The inexpensive optical connector having excellent mass productivity is thereby provided.

摘要： PURPOSE:To prevent an end surface from breaking and to facilitate the handling of an optical connector by coupling an elastic member which has a smaller elastic modulus than a ferrule main body with the tip side of the main body, forming a core conductor insertion hole penetrating the ferrule main body and elastic member, and forming a curved surface atop of the elastic member. CONSTITUTION:The elastic member 17 made of resin is coupled integrally with the ferrule main body 11 with an adhesive, etc., and the core conductor insertion hole 15 is formed finely and coaxially in the ferrule main body 11 and elastic member 17. Further, the tip of a core conductor 14 is ground into a curved surface shape of about R60 together with the tip of the elastic member 17. Then, a coil spring 16 is interposed between the rear end of the flange 12 and the front end of a holding member 19 to press the ferrule main body 11 forward. This optical connector plug 10 is inserted into an adapter side and then the tip of the core conductor 14 contacts the core conductor of the opposite side coaxially and the coil spring 16 presses the ferrule main body 11 forward to bring the core conductors into mutual contact. Consequently, the core conductors 14 are connected excellently at all times by the spring with small pressing force without being affected by the temperature variation.
