Abstract: In a female crimp terminal including a pressure-bonding section for permitting pressure-bonding and connection to an aluminum core wire of an insulated wire, the pressure-bonding section is configured in a hollow sectional shape by a plate material, and a long length direction weld portion in a long length direction is welded, a forward part in the hollow sectional shape is caused to take an almost flat plate-shaped sealing shape and a width direction weld portion in a width direction is welded.

Abstract: A crimp terminal (10) comprises a box part (20) and a cable connector (30). The box part (20) is connected to another terminal. The cable connector (30) is coupled with the box terminal (20) and connected with a covered cable (50). Also, the cable connector (30) includes a hollow formed by welding a metal plate, in which a pressing part for conduction (33b) and a compression part for waterproofing (33a) are formed. The pressing part for conduction (33b) presses a conduction part (51) of the covered cable (50) to ensure conduction with the covered cable. The compression for waterproofing (33a) presses and compresses a covered part (52) of the covered cable (50) inwardly to prevent water from entering inside.

Abstract: A crimp terminal includes barrel pieces respectively on both of two sides in a width direction thereof. The barrel pieces are included in a pressure-bonding section for pressure-bonding an exposed part of an electric wire conductor of an insulated wire. The insulated wire includes the electric wire conductor and an insulating cover for covering an outer circumference of the electric wire conductor, and the exposed part is a part of the electric wire conductor which is exposed from a tip of the cover by a predetermined length. The barrel pieces have a length in a longitudinal direction which is longer than the length of the exposed part of the electric wire conductor. The pressure-bonding section pressure-bonds, by the barrel pieces, a continuous part from a tip of the electric wire conductor to a position rear to the tip of the cover.

Abstract: A circuit board is formed such that a printed circuit board is connected to an injection molded circuit board. An internal circuit conductor is exposed at conductor part at a printed circuit board mounting part. Through holes are provided in the printed circuit board. The conductor part is formed substantially perpendicular to the circuit board mounting part, and is inserted into a through hole. A female screw part is formed in the vicinity of the conductor part in the printed circuit board mounting part. The female screw part can be screwed together with a bolt, which is a securing member. The printed circuit board is connected to the conductor part by solder. A hole is formed in advance in the vicinity of the solder on the printed circuit board. The bolt passes through the hole and is secured to the female screw part.

Abstract: A method for producing a ferrule having a plurality of fiber holes for insertion of optical fibers formed between two pin holes for insertion of guide pins, and a ferrule produced by the method. The method comprises a step of injecting a synthetic resin in a mold for forming the ferrule while holding a plurality of pins with a Young's modulus of(22 to 59)×1010N/m2 for forming the fiber holes at two points separated by a distance of 1.5 to 4 mm in a lengthwise direction of the pins.

Abstract: 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.

Abstract: A ferrule for a multi optical connector is formed by filling a cavity in a mold with melted resin and the ferrule is pushed out of the cavity by pressing a face on the side in which an adhesive pouring port is formed of the formed ferrule. Two positions on both outer sides with respect to a center line in the arrangement direction of the fiber or three or more positions including those two positions, near a joint end face on a face on the side in which the adhesive pouring port is formed, are pressed.

Abstract: A method for manufacturing an optical connector ferrule according to the present invention is a method for manufacturing an optical connector ferrule where a plurality of fiber holes are arranged between two guide pin holes, wherein melted material resin is injected from one resin injection port into a cavity of a forming mold where two forming pins for forming the guide pin holes and a plurality of forming pins for forming the fiber hole are arranged in parallel to one another. A forming mold according to the present invention is provided with a cavity where a plurality of forming pins can be arranged in parallel to one another, and one resin injection port through which melted material resin can be injected into the cavity.

Abstract: A ferrule manufacture method for molding, with a die, a ferrule having pin holes each for inserting a guide pin therethrough; a plurality of fiber holes provided between the pin holes each for inserting an optical fiber therethrough, and an inlet port for introducing optical fibers therein, in which the optical fibers are adhered and fixed to the fiber holes with adhesive injected from the inlet port, and the ferrule. A plurality of pins for forming a plurality of fiber holes are held by a holding member, and a support member for supporting the guide pins or the holding member is located in the molding process within the die between positions corresponding to a front end face and a rear end face of the ferrule to be molded.
