Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber access automatic detection mechanism and an optical fiber coupler. Background Art

[0002] In the field of modern communications, optical fiber technology has become one of the main ways of data transmission due to its advantages such as high transmission rate, large bandwidth and anti-interference ability. As a key component in the optical fiber communication system, the performance of optical fiber access equipment directly affects the performance and reliability of the entire communication system. Therefore, ensuring the accurate access and stable connection of optical fiber connectors is an important prerequisite for achieving efficient communication.

[0003] Traditional fiber access equipment usually relies on manual operation to complete the connection of fiber connectors, which is not only inefficient, but also prone to unstable or damaged fiber connections due to improper operation. In addition, manual operation cannot achieve automated detection and cannot monitor the fiber connection status in real time, thus failing to ensure communication quality.

[0004] In order to solve the above problems, technicians in this field have conducted a lot of research and developed a variety of automatic fiber access detection mechanisms. These mechanisms achieve automatic insertion and detection of optical fiber connectors through the ingenious design of mechanical structures. However, the automatic detection mechanisms in the prior art still have some shortcomings, such as complex structure, high cost, and difficult maintenance. Summary of the invention

[0005] The purpose of the utility model is to provide an automatic detection mechanism for optical fiber access and an optical fiber coupler to address the problems existing in the prior art. The mechanism has a simple structure, low cost, and is easy to maintain. The accuracy and stability of optical fiber access are improved, while automated detection is realized to ensure communication quality.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An automatic optical fiber access detection mechanism, comprising:

[0008] A flange seat is fixedly arranged on the outer side of the optical fiber equipment housing and is provided with an interface column for connecting with an optical fiber connector;

[0011] The micro switch is fixed on the inner side of the optical fiber device housing; when the optical fiber connector is inserted to the set position, the sensing rod triggers the micro switch to send a detection position signal.

[0012] Furthermore, it also includes a support and limiting ring, which is arranged between the contact ring and the flange seat and fixed to the outside of the optical fiber equipment housing, and the support and limiting ring is provided with a guide hole for the sensing rod to pass through.

[0013] Furthermore, a reset spring is provided on the sensing rod, one end of which is connected to the baffle of the sensing rod, and the other end is connected to the support limiting ring, and is used to reset the contact ring after the optical fiber connector is pulled out.

[0014] Furthermore, a shaft sleeve is provided on the back end face of the contact ring, and the shaft sleeve passes through the center hole of the support limiting ring and is connected to the limiting clamp ring, and the limiting clamp ring abuts against the back end face of the support limiting ring to maintain the compression state of the return spring.

[0015] Furthermore, the interface column of the flange seat is connected to the tail sleeve of the optical fiber connector by using external threads, and the outer end surface of the contact ring is used to abut against the tail sleeve of the optical fiber connector.

[0016] Furthermore, it also includes a switch fixing block arranged on the inner side of the optical fiber equipment housing, which is used to fix the micro switch to the optical fiber equipment housing.

[0017] An optical fiber coupler comprises the above-mentioned optical fiber access automatic detection mechanism.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0020] Compared with the traditional complex detection mechanism, the design of the utility model is simpler, reducing the number of components and the complexity of the mechanical structure, thereby reducing the manufacturing cost and maintenance difficulty, and further reducing the overall use cost;

[0021] By providing a support limit ring and a guide hole, the utility model ensures the stability of the sensing rod during movement and avoids detection errors caused by unstable movement;

[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the first aspect of this application, Figures 1 to 3 As shown, an automatic detection mechanism for optical fiber access is provided, comprising: a flange seat 1, fixedly arranged on the outer side of an optical fiber device housing 6, and provided with an interface column for connecting to an optical fiber connector 10; a contact ring 2, movably sleeved on the interface column through a hole therein; when the optical fiber connector 10 is inserted into the interface column, the outer end face of the contact ring 2 abuts against the optical fiber connector, and synchronously moves in the same direction as the optical fiber connector 10 is inserted; a sensing rod 3, a first end of which is connected to the back end face of the contact ring 2, and a second end passes through the optical fiber device housing; a micro switch 4, fixedly arranged on the inner side of the optical fiber device housing 6; when the optical fiber connector 10 is inserted into the set position of the interface column, the second end of the sensing rod 3 contacts the micro switch 4, and the micro switch 4 sends a detection position signal.

[0033] Among them, the optical fiber can adopt 905 optical fiber, and the flange seat adopts 905 flange seat. After the above components are installed in the optical fiber equipment housing 6, the optical fiber connector 10 is aligned with the interface column of the flange seat 1 and inserted. During the insertion process of the optical fiber, the tail sleeve on the optical fiber connector 10 is rotated to slowly push the contact ring 2 forward, and the contact ring 2 synchronously pushes the sensing rod 3 to move in the same direction. When the optical fiber connector is inserted into the set position of the interface column, the second end of the sensing rod 3 just contacts the micro switch 4, and the micro switch 4 sends a detection position signal, indicating that the optical fiber is inserted in place.

[0034] When designing the structure, the telescopic stroke of the sensing rod 3 should be calculated according to the size specifications of the optical fiber connector 10, so that the optical fiber connector 10 is inserted into place and the sensing rod 3 just touches the micro switch. By setting up an automatic optical fiber access detection mechanism, it can be identified whether the optical fiber is well connected to ensure good light output.

[0035] In some embodiments, the optical fiber access automatic detection mechanism further includes a support stop ring 5, which is disposed between the contact ring 2 and the flange seat 1 and fixed to the outer side of the optical fiber device housing 6, and the middle hole of the support stop ring 5 movably passes through the interface column; the support stop ring 5 is provided with a guide hole, and the sensing rod 3 movably passes through the guide hole. The support stop ring 5 ensures the stable movement of the sensing rod 3.

[0036] In some embodiments, two sensing rods 3 are provided, and two corresponding guide holes are provided in the support stop ring 5. The sensing rods 3 are symmetrically arranged to ensure that the contact ring moves stably and avoids deviation to one side.

[0037] It should be noted that a person skilled in the art can easily think of providing more than two sensing rods 3 without requiring creative work, and all of these are within the protection scope of the present application.

[0038] In some embodiments, a reset spring 7 is sleeved on the sensing rod 3, a baffle is provided at the first end of the sensing rod 3, one end of the reset spring 7 is connected to the baffle, and the other end is connected to the support limit ring 5, and the first end of the sensing rod 3 is in contact with the contact ring 2. When the optical fiber connector 10 is pulled out, the reset spring 7 resets the sensing rod 3, and the sensing rod 3 pushes out and resets the contact ring 2, which is convenient for the next optical fiber insertion detection.

[0039] In some embodiments, a sleeve is provided in the middle of the back side end face of the contact ring 2, and the contact ring 2 is sleeved on the interface column through the sleeve, and the sleeve passes through the middle hole of the support limit ring 5 and is connected to the limit clamp ring 8, and the limit clamp ring 8 abuts against the back side end face of the support limit ring 5, so that the reset spring 7 is in a compressed state. The compressed reset spring 7 applies pressure to the contact ring 2, and the limit clamp ring 8 contacts the ring 2 to limit the position, so that the contact ring 2 is installed stably; in the structural design, a gap is left between the support limit ring 5 and the optical device, and when the optical fiber connector 10 is inserted, the contact ring 2 can drive the limit clamp ring 8 to move toward the device side.

[0040] In some embodiments, the interface column of the flange seat 1 is connected to the tail sleeve of the optical fiber connector through an external thread, and the outer end face of the contact ring 2 is used to abut against the tail sleeve of the optical fiber connector. The outer thread of the tail sleeve and the interface column interact to achieve a tight connection of the optical fiber connector; the tail sleeve contacts the outer end face of the contact ring 2, and the direct insertion thrust is too large by rotating and pushing. Damage to the micro switch.

[0041] In some embodiments, the mechanism further includes a switch fixing block 9 disposed inside the optical fiber device housing 6 , and the micro switch 4 is fixed to the optical fiber coupler housing 6 via the switch fixing block 9 .

[0042] A second aspect of the present application provides a fiber optic coupler, comprising the above-mentioned automatic fiber access detection mechanism.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
