Abstract:
A blind hole insert fixing device is configured for fixing a number of blind hole inserts. The blind hole insert fixing device includes a hollow housing defining a cavity and an engagement member received in the cavity. The housing includes a first inner surface and an opposing second inner surface in the cavity. The engagement member includes a body portion, a number of spring portions, and a number of engagement portions conforming to the blind hole inserts. The spring portions and the engagement portions are located at opposite sides of the body portion. The spring portions abut against the first inner surface. The engagement portions and the second inner surface cooperatively form a number of receiving spaces for receiving the blind hole inserts. The spring portions are configured for applying a force to the body portion in a direction away from the first inner surface.
Abstract:
A lens testing device includes a light source assembly, a pattern plate, and an imaging sensor. The light source assembly includes a transparent base plate, a light guide plate, and a number of illuminants. The light source assembly uses the light guide plate to uniformize a light come from the illuminants and emit the light onto the pattern plate. The imaging sensor is placed beneath the transparent base plate to sense the light passing through the pattern plate and focused by a lens.
Abstract:
An exemplary molding insert core used in an insert mold includes two first molding bars, two second molding bars, two first support members, and two second support members. Each first molding bar is partially arranged on one first support member. Each second molding bar is partially arranged on one second support member.
Abstract:
A contact image sensor module includes an image sensor, a lens unit arranged over the image sensor, a glass plate arranged over the lens unit, and a light source. The lens unit includes a plurality of rod lenses. The glass plate is wedge-shaped and elongated. The glass plate includes a first light interface being rectangular and elongated, and a second light interface and an incident face respectively extending from two opposite longer sides of the first light interface. The incident face faces the light source. The first light interface is substantially perpendicular to the rod lenses. The second light interface is below the first light interface and faces top sides of the rod lenses. Light of the light source is first directed by the glass plate to the document, then reflected by the document to the lens unit via the glass plate and finally reaching the image sensor.
Abstract:
An exemplary optical fiber connector includes a housing, and two lenses. The housing defines two blind holes each configured for receiving an optical fiber. The two lenses are formed on the housing and each of the lenses is aligned with a corresponding blind hole. Each of the blind holes includes a first cylindrical hole portion, a tapered hole portion and a second cylindrical hole portion facing a corresponding lens, and a diameter of the tapered hole portion gradually decreases from the first cylindrical hole portion towards the second cylindrical hole portion.
Abstract:
An optical fiber connector includes a first transmission member, a second transmission member engaged with the first transmission member, and an elongated shielding member. The first transmission member includes a first body and two lenses. The first body includes an upper surface, a lower surface parallel to the upper surface, and a front surface connecting the upper surface to the lower surface. A recess is defined in the upper surface and exposed at the front surface. The first body includes a first light coupling surface and a sealing surface in the recess. The second transmission member includes a second body having a second light coupling surface facing the first light coupling surface. The shielding member is fixed on the upper surface above the recess. The shielding member cooperates with the two light receiving surfaces, and the sealing surface to form a sealed room for receiving the two lenses.
Abstract:
A photoelectric converter includes a laser diode, a female optical transmission module, a male optical transmission unit, and a photo diode. The female optical transmission module includes a plurality of first lenses and a plurality of second lenses oriented at ninety degrees from each other, with total internal reflection between the two lenses. The female optical transmission module defines a detection cutout, from which the first lenses and the second lenses can be observed simultaneously. The photoelectric converter has a high reliability in signal transmittance.
Abstract:
A photoelectric converter includes a circuit board, a laser diode electrical mounted on the circuit board, a supporting frame, an optical transmission member mounted on the supporting frame, a beam splitting assembly and an optical sensor positioned beside the beam splitting assembly. The laser diode, the beam splitting assembly and the optical sensor are received in a space cooperatively defined by the supporting frame and the optical transmission member. The laser diode emits optical signals. A part of optical signals is refracted by the beam splitter and transmitted to the optical transmission member, and the other part of optical signals is reflected by the beam splitter to the optical sensor.
Abstract:
An optical fiber connector including a main body and a block is illustrated. The main body includes a first side, an opposite second side, and a first top surface between the first side and the second side. The first side includes at least two protruding lenses. The first top surface defines a recess, and the recess includes an open end at the second side. The block is securely retained within the recess. The block defines at least two through holes respectively aligned with the at least two lenses. Each of the at least two through holes is securely retaining one optical fiber.
Abstract:
An optical fiber coupling connector includes a female port, a male port, a plurality of optical fibers, and a plurality of signal wires. The female port includes a first inserting portion and a second inserting portion. The second inserting portion includes a housing and a plurality of lenses fixed within the housing. The housing includes a receiving chamber. The plurality lenses separate the receiving chamber to a first inserting hole and a second inserting hole at opposite sides of the lenses. The first inserting portion is inserted into the first inserting hole, and the male port is inserted into the second inserting hole of and coupled with the female port. The optical fibers are inserted into the male port. The signal wires are inserted into the first inserting portion of the female port. The lenses couple the plurality of optical fibers and the signal wires.
