摘要:
An optical connector housing having arm portions extending from both end sides of the face of the base end side. A space placed between the arm portions is constituted as ferrule accommodation space. An engaging portion which is engaged in an object to be connected is formed at the tip end side of the respective arm portions. A surface of an angle widening drive cam, which widens the arm portions when the ferrule is drawn to the face of the base end side, protrudes from and is formed on the inner wall of the arm portions extending from the position of the rear end face of the ferrule accommodated in the accommodation space to the base end side of the optical connector housing.

An optical connector for making connection with a connecting partner side and releasing this connection is provided. The optical connector has an optical connector housing. The optical connector housing is formed by inserting a slider into a base end wall of an arm side member so as to be freely advanced and retreated. A cam following face is formed on an inner wall face of an arm portion of the arm side member. A claw portion is formed on a tip side of the arm portion. An opening angle driving cam member is connected to a tip side of the slider. A ferrule is arranged between the arm portions on a forward side of the opening angle driving cam member. When the slide is moved backward, the opening angle driving cam member is moved backward and is operated to angularly open the arm portion through the cam following face. This opening angle state is maintained by making the opening angle driving cam member abut on a stationary face of the cam following face. The claw portion is dislocated from an engaging position with the connecting partner side by the angular opening of the arm portion so that the connection of the optical connector is released.

The invention is directed to a method of manufacturing an optical connector according to which it is possible to adjust a projection length a bare optical fiber (7) projects from a connection end surface (3) of a ferrule (1). At a step (a), an optical fiber cored line (5) is inserted through and attached to an optical fiber insertion hole (4) of the ferrule (1), and the bare optical fiber (7) and the ferrule (1) are bonded to each other by hardening a heat-hardening adhesive (11) at a first hardening temperature. Next, at a step (b), the connection end surface (3) is ground so that the connection end surface (3) becomes flat and flush with a tip surface of the bare optical fiber (7). Following this, at a step (c), the heat-hardening adhesive (11) is heated again to be hardened at a temperature which is higher than the first hardening temperature, so that a tip of the bare optical fiber (7), causing pistoning due to the reheat hardening, projects from the connection end surface (3). The quantity of the projection is adjusted by controlling one or both of the rehardening temperature and a holding time at the rehardening temperature.
摘要:
A ferrule for an optical connector wherein the work efficiency of the manufacture is increased by reducing the time necessary for grinding and the reliability of the connection of the optical connectors is improved. A front end surface (2) of a ferrule (1) comprises a flat surface (16) vertical to the central axes of optical fiber insertion holes (3) and a slanting surface (15). A step (17) is provided at the upper end of a slanting surface (15) and the flat surface (16) protrudes frontward by the step (17) with respect to the slanting surface (15). The optical fiber insertion holes (3) open at the slanting surface (16) and pin engagement holes (4) are provided on both sides of the optical fiber insertion holes (3).
摘要:
A manufacturing apparatus for multi-fiber optical ferrule includes a spacer whose hardness is equivalent to or higher than the hardness of pins for forming fiber holes. Further, corner portions with respect to the arrangement direction of the pins for forming fiber holes of the spacer are formed as inclined surfaces or rounded surfaces.

The present invention relates to a method of manufacturing a painted golf ball with reduced static electricity on the surface of the golf ball prior to painting to allow even painting to produce a ball without asperity on the surface, characterized by irradiating the surface of the golf ball, which is positively charged before painting, with negative ions directly before painting. Preferably, the surface of the golf ball after the irradiation with negative ions and prior to the painting is negatively charged, and particularly, the surface of the golf ball after the irradiation with negative ions prior to the painting is preferably charged at −0.1 to −40 kV.
摘要:
A method of collectively connecting multiple optical connectors each having an altered-shape portion which is at least one of a recessed shape or a projecting shape on an outer surface, and an aligning and positioning jig used in this method. After multiple optical connectors are aligned and positioned by using an aligning and positioning jig for engaging the altered-shape portions of the multiple optical connectors to one another to position the multiple optical connectors, multiple optical connectors aligned and positioned on one side are collectively connected to multiple optical connectors aligned and positioned on the other side. Then the aligning and positioning jig is removed from multiple pairs of connected optical connectors.
摘要:
Disclosed in an optical switching connector provided with a first and second ferrule disposed with end faces thereof abutting on each other and two reference pins disposed in parallel at a predetermined interval. The first and second ferrules have two parallel pin holes, respectively. The two reference pins are inserted in the pin holes. The pin holes have an elongated sectional shape enabling the reference pins to move laterally by exactly a certain movement pitch. The first and second ferrules are able to be positioned at one position determined by one of the inside surfaces of the pin holes being pressed against the reference pins and another position determined by the other inside surfaces of the pin holes being pressed against the reference pins. One of the first and second ferrules has fixed in it two or more optical fibers at a pitch of 1/n (n being a positive integer) of the above-mentioned certain movement pitch, while the other ferrule has fixed in it one or more optical fibers so to correspond with all or part of the same.
摘要:
A cover peeling machine includes a pair of rolls. The roll has an almost conical shape. Both of the rolls are rotated in a reverse direction. The direction of the rotation is an inward direction as seen from above. A golf ball is put close to a tip of the roll. In the vicinity of the tip, a distance between a nip of the roll and the golf ball is short. Therefore, a clip portion formed on the golf ball can be easily bitten between the rolls. With the rotation of the roll, a cover is peeled from a core. A groove formed on a surface of the roll can prevent the roll and the cover from slipping. After the removal, the cover and the core are recycled respectively.
