Abstract: The present invention discloses a toy rifle, comprising a first grip, a second grip, a grip protector, a front frame, a rear frame, a sliding component, a trigger and a restrainer, wherein the first grip and second grip are fixedly connected with the front frame. The sliding component is used to joint the front frame and the rear frame. Through arranging structures such as a sliding component, a cylinder, a gas nozzle, a gas transmission unit, and a restrainer, etc., and when the trigger is pulled, the gas in the external gas pump enters into the cylinder at the gas nozzle through the pipe, thereby driving the sliding component to move. The movement of sliding component produces a reverse force, thereby forming a recoil force which is transferred to the player, thereby increasing the simulation effect and experience.

Abstract: Example optical connector ferrules and example optical connectors are provided. An example optical connector ferrule is a first ferrule of an optical connector, where the first ferrule includes n optical channels, and the first ferrule is configured to be compatible with a second ferrule. The second ferrule includes m optical channels, where both m and n are positive integers, and n is greater than m. The n optical channels of the first ferrule include first-type optical channels and second-type optical channels, where an arrangement manner of the first-type optical channels is the same as that of the m optical channels of the second ferrule, and at least one of the second-type optical channels is located in at least one of rows in which the first-type optical channels are located.

Abstract: A ferrule includes a ferrule matrix, an optical fiber, and a dielectric reflective film. The optical fiber is disposed in an accommodating through hole of the ferrule matrix, and the dielectric reflective film covers an optical transmission surface of the optical fiber and a surface that is of the ferrule matrix and that faces a matching ferrule. The dielectric reflective film has a through hole, such that the dielectric reflective film does not shield a main optical path area of the optical transmission surface of the optical fiber. A reflective band of the dielectric reflective film includes at least a part of a communication band of the optical fiber. In this way, when light from the matching ferrule is transmitted to the ferrule matrix and the optical fiber, the dielectric reflective film reflects the light.

Abstract: A ferrule is provided, the fiber is inserted into a through hole axially disposed in the ferrule body, a first end of the fiber is located inside the through hole, a vertical distance between an end face of the first end of the fiber and a plane on which a connection end face of the ferrule body is located is a first preset distance, and the first preset distance is a distance that can leave a gap between a fiber of the ferrule and a fiber of another ferrule after the ferrule abuts the another ferrule.
