Claims (1)

[Claims for Utility Model Registration] (1) In a method of supporting an optical fiber on a circuit board, a through hole or a hole with a land is provided in advance in the vicinity of the fiber support point on the circuit board, and this A pin is prepared in accordance with the number of support points, and is made of a springy metal wire having a diameter that engages with the hole, and has a loop formed with a hook at the top so that a fiber can be inserted and supported. An optical fiber support structure characterized in that the optical fiber is fixed by soldering into a hole provided in a circuit board and is supported by passing the fiber through a ring at the top. (2) A pin with a metal wire having spring properties that engages with a hole provided in a circuit board and a ring with a hook at the top that inserts and supports a fiber, and a pin that fits into this pin and whose outer diameter is Prepare a cylindrical sleeve that is larger than the hole made on the circuit board, insert this sleeve into the pin, and swage it onto the pin at the position where the pin top and sleeve end meet the specified dimensions, so that the sleeve end is attached to the circuit board. 1. An optical fiber support structure characterized in that a pin is inserted and soldered until it touches a hole provided in a hole, and the fiber is supported by passing it through a ring at the top. (3) A pin with a metal wire having spring properties that engages with a hole provided in a circuit board and a ring with a hook formed on the top for inserting and supporting a fiber, and a pin that is crimped to this pin and is pressed with a specified force. Attach a movable cylindrical elastic sleeve so that the top of the pin is at a predetermined height on the circuit board, insert the pin until the end of the elastic sleeve touches the hole in the circuit board, fix it by soldering, and connect the fiber with the ring at the top. An optical fiber support structure characterized by supporting. (4) A metal wire with spring properties that engages with a hole provided in the circuit board is molded with a ring at the top with a hook for inserting and supporting the fiber, and the other end is stepped in the middle by pressing or machining. The present invention is characterized in that a pin having a straight part with a fitting part is prepared, the pin is inserted until the stepped part touches a hole provided in a circuit board, and the pin is fixed with solder, and the fiber is supported by the ring at the top. Optical fiber support structure. (5) A ring with a hook is formed on the top of the wire to insert and support the fiber, and the other end is a pin with a straight section, and a stepped section is provided in the middle of this straight section. A cylindrical metal sleeve that abuts and rotationally engages the straight part of the pin is attached, and the pin end is caulked to prevent the sleeve from falling off. Meanwhile, a pin is prepared that is configured to prevent the sleeve from falling off. The optical fiber is characterized in that a hole with a land or a through hole is provided at a location that serves as a fiber support point, the sleeve of the pin is soldered to this hole, and the fiber is supported by a ring at the top. Support structure. (6) A metal wire with spring properties is molded into a ring with a hook at the top to insert and support a fiber, and the other end is a straight pin with a slotted part at the tip, and on the other hand, A through hole or a hole with a land, which is slightly thinner than the wire diameter of the pin, is provided on the circuit board to which the fiber is wired so that the fiber can be fixed independently by the elasticity of the slotted portion of the pin, and the pin is temporarily fixed in this hole. , an optical fiber support structure characterized in that the fiber is fixed with solder afterward and the fiber is supported by a ring at the top.
