Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber connectors, and more particularly to an interface for detecting an end face of an optical fiber connector. Background Art

[0002] Fiber optic connectors, also called fiber optic adapters, are devices for detachable connection between optical fibers. They precisely connect the two end faces of optical fibers, so that the light energy output by the transmitting optical fiber can be coupled into the optical fiber to the maximum extent, and the impact on the system caused by its involvement in the optical link is reduced to a minimum. To a certain extent, fiber optic connectors will also affect the reliability and performance of the optical transmission system, so usually before docking, the end face of the fiber optic adapter should be inspected for scratches and dirt spots to meet the basic requirements of the optical path system and reduce the errors caused by fiber optic docking.

[0003] At present, the fiber optic connectors on the market are used in pull-ring modules, chassis cabinets, optical modems, etc., and usually use straight-head detection interfaces. However, the straight-head detection interfaces have the following shortcomings: the straight-head detection interface will interfere with the pull-ring when detecting modules with pull-rings; for optical modems and data center chassis cabinets, the straight-head detection interface is too long after being installed on the body of the detector, and the straight-head detection interface cannot be inserted into the fiber optic connector.

[0004] In summary, the straight head detection interface will cause inconvenience in operation due to insufficient operating space. Summary of the invention

[0005] By reading the specification, ordinary technicians in this field will have a better understanding of the characteristics and contents of these technical solutions.

[0006] The technical problem to be solved by the present invention is to provide an interface for detecting the end face of an optical fiber connector, which will not cause the problem of inconvenient operation due to insufficient operating space.

[0007] The technical solution of the present invention is: to provide an interface for end face detection of optical fiber connectors, including an interface body, wherein the interface body has two through ports, and there is an angle between the axes of the two ports of the interface body, and the angle is an obtuse angle, so that the interface is curved, one of the ports of the interface body is used to connect the optical fiber connector, and the other port of the interface body is used to connect the detector.

[0008] The interface body comprises a first connector and a second connector which are connected to each other. The two ports of the interface body are respectively a first port and a second port. The first port is arranged on the first connector and is used to connect to the detector. The second port is arranged on the second connector and is used to connect to the optical fiber connector.

[0009] The first connecting body is also provided with a third port communicating with the first port, and an axis of the first port and an axis of the third port form an included angle. The second connecting body is also provided with a fourth port communicating with the second port, and the fourth port is connected to the third port, and the axis of the second connecting body is parallel to the axis of the third port.

[0010] A reflector is disposed in the interface body, and the reflector is used to reflect light entering from one of the ports of the interface body and emit the light from the other port of the interface body.

[0011] A movable lens is arranged in the interface body.

[0012] A lens barrel is also provided in the interface body, and the lens is mounted at one end of the lens barrel. The lens barrel moves in the second connecting body to drive the lens to move.

[0013] A circle of protrusions is provided on the outer circumferential surface of the other end of the lens barrel, and a circle of first limiting bosses is provided on the inner surface of the interface body. An elastic member is sleeved on the lens barrel and the two ends of the elastic member are located between the protrusions and the first limiting bosses. The lens barrel is pushed to move toward one of the ports of the interface body by an external force, and the lens barrel is pushed to move toward one of the ports of the interface body by the spring.

[0014] A sliding piece is arranged in the interface body, and the sliding piece is arc-shaped. The sliding piece is used to push the lens barrel to move toward the direction close to one of the ports of the interface body.

[0015] A mounting seat is also provided in the interface body, a slide groove is provided on the mounting seat, and the sliding member is arranged in the slide groove.

[0016] The other port of the interface body is provided with a movable sleeve, through which the sliding member is pushed to slide; the sliding member has two contact ends, namely a first contact end and a second contact end, the second mounting end of the lens barrel abuts against the first contact end of the sliding member, and the second contact end of the sliding member abuts against the sleeve.

[0017] In the present invention, since there is an angle between the axes of the two ports of the interface body, after the interface is installed on the body of the detector, the body of the detector will form a certain angle with the interface, avoiding the problem of the interface being too long and reducing the volume of the interface. Even if the operating space is small, the end face of the optical fiber connector can be inspected without causing inconvenience in operation due to insufficient operating space, thereby enabling the end face of the optical fiber connector to be inspected in more space environments.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with examples, and the advantages and implementation methods of the present invention will become more obvious. The contents shown in the accompanying drawings are only used to explain the present invention and do not constitute any limitation to the present invention in any sense. In the accompanying drawings:

[0020] Figure 2 It is an exploded diagram of the interface in the embodiment of the present invention.

[0021] Figure 3 It is a cross-sectional view of the interface in the embodiment of the present invention. DETAILED DESCRIPTION

[0022] like Figure 1 and Figure 2 As shown, the interface for detecting the end face of an optical fiber connector proposed in an embodiment of the present invention includes an interface body 1, the interface body 1 has two ports that pass through, and the axes of the two ports of the interface body 1 have an angle between them, so that the interface is curved, and the angle is not zero or 180 degrees. In this embodiment, the angle is an obtuse angle, that is, greater than 90 degrees. The two ports of the interface body 1 are respectively a first port 11 and a second port 22, the first port 11 is used to connect the detector, and the second port 22 is used to connect the optical fiber connector. In this embodiment, since there is an angle between the axis of the first port of the interface body and the axis of the second port of the interface body, after the interface is installed on the body of the detector through the first port, the body of the detector will form a certain angle with the interface, avoiding the problem of the length of the interface being too long, reducing the volume of the interface, and even if the operating space is small, the end face of the optical fiber connector can be detected, and the problem of inconvenient operation will not be caused due to insufficient operating space, so that the end face of the optical fiber connector can be detected in more space environments.

[0023] The interface body includes a first connector 10 and a second connector 20, the second connector 20 is a straight line, the first port 11 is provided on the first connector 10, and the second port 22 is provided on the second connector 20. The first connector 10 is also provided with a third port 12 that is connected to the first port 11, and the axis of the first port 11 and the axis of the third port 12 have an angle, so that the first connector 10 is curved. The second connector 20 is also provided with a fourth port 23 that is connected to the second port 22, the fourth port 23 is connected to the third port 12, and the axis of the second connector 20 is parallel to the axis of the third port 12.

[0024] A reflector 60 is disposed in the first connecting body 10. After light enters the second connecting body 20, it is reflected by the reflector 60 and emitted from the second port of the first connecting body 10, and finally enters the body of the detector. In this embodiment, the reflector 60 is a reflector.

[0025] like Figure 2 and Figure 3 As shown, the second connector of the interface is inserted into the optical fiber connector to detect the size of dirt and scratches on the end face of the optical fiber connector. However, in order to clearly see the size of the dirt and scratches, a movable lens 30 is provided in the second connector 20. The lens 30 is moved in the second connector 20 to adjust the clarity, thereby achieving focusing.

[0026] In order to facilitate the installation of the lens 30, a lens barrel 40 is further provided in the second connecting body 20. The lens barrel 40 has a first mounting end and a second mounting end. The first mounting end of the lens barrel 40 is close to the second port 22 of the second connecting body 20, and the second mounting end of the lens barrel 40 is far away from the second port 22 of the second connecting body 20. The lens 30 is mounted on the first mounting end of the lens barrel 40, and the lens 30 is driven to move by the movement of the lens barrel 40 in the second connecting body 20. A circle of protrusions 41 is provided on the outer circumferential surface of the second mounting end of the lens barrel 40, and a circle of first limiting bosses (not shown in the figure) is provided on the inner surface of the second connecting body 20. An elastic member 50 is sleeved on the lens barrel 40, and the two ends of the elastic member 50 are located between the protrusions 41 and the first limiting bosses. When an external force pushes the second mounting end of the lens barrel 40, the lens barrel 40 moves to the right (i.e., close to the direction of the second port), thereby driving the lens 30 to move to the right. When the external force disappears, the lens barrel 40 moves to the left under the action of the elastic member, thereby driving the lens 30 to move to the left (i.e., away from the direction of the second port).

[0027] In this embodiment, the elastic member 50 is a spring.

[0028] A circle of second limiting bosses 21 is provided on the inner surface of the second connecting body 20 to limit the distance that the lens barrel moves to the right.

[0029] In order to facilitate the promotion of the lens barrel 40, a sliding member 70 is provided in the first connecting body 10, and the lens barrel 40 is pushed to move to the right (can be manually pushed or driven by a motor) by the sliding member 70, and the lens barrel 40 is pushed to move to the left by the spring 50. A mounting seat 80 is also provided in the second connecting body 20, and a slide groove 81 is provided on the mounting seat 80, and the sliding member 70 is arranged in the slide groove 81 so that the sliding member 70 slides in the slide groove 81. In the present embodiment, the sliding member is arc-shaped and is in a sheet shape. The reflector 60 is fixed in the first connecting body 10 by a solid glue 120, and the mounting seat 80 is connected to the first connecting body 10 by a pin 130.

[0030] The first port of the first connector 10 is provided with a movable sleeve 90, and the sliding member 70 is pushed to slide by the sleeve 90. The sliding member 70 has two contact ends, namely a first contact end and a second contact end. The second mounting end of the lens barrel 40 abuts against the first contact end of the sliding member 70, and the second contact end of the sliding member 70 abuts against the sleeve 90.

[0031] The following is a detailed description of the principle of the interface:

[0032] The sleeve 90 is pushed upward, and then the sliding member 70 is pushed upward, and then the lens barrel 40 is pushed to the right through the first contact end of the sliding member 70, thereby driving the lens 30 to move to the right. In this process, the spring is compressed; when the external force on the sleeve 90 disappears, the lens barrel 40 is pushed to the left through the restoring force of the spring, and then the sliding member 70 is pushed downward, and then the sleeve 90 is pushed downward to reset, and the lens 30 is focused in the process of moving to the left or right. The image focused by the lens is reflected by the reflector and enters the body of the detector, and is observed through CCD imaging, so as to detect and judge the end face of the optical fiber.

[0033] A nut 100 is provided on the outer sleeve of the first port of the first connector, and the interface is fixed to the body of the detector through the nut 100. An open retaining ring 110 is provided on the outer surface of the second port of the first connector 10 to limit the nut 100.

[0034] The interface proposed by the present invention has an angle between the axes of the two ports of the interface body. After the interface is installed on the body of the detector, the body of the detector will form a certain angle with the interface, avoiding the problem of the interface being too long and reducing the volume of the interface. Even if the operating space is small, the end face of the optical fiber connector can be inspected, and the problem of inconvenience in operation will not occur due to insufficient operating space. The end face of the optical fiber connector can be inspected in more space environments, meeting the requirements for end face inspection of pull-ring type optical fiber connector modules, meeting the requirements for end face inspection of optical fiber connectors of different optical modems, and meeting the requirements for end face inspection of optical fiber connectors in data centers such as chassis and cabinets.

[0035] The preferred embodiments of the present invention are described above with reference to the accompanying drawings. A person skilled in the art may implement the present invention in a variety of variations without departing from the scope and essence of the present invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to obtain another embodiment. The above are only preferred feasible embodiments of the present invention, and do not limit the scope of rights of the present invention. Any equivalent changes made using the contents of the present specification and the accompanying drawings are included in the scope of rights of the present invention.
