Description

Technical Field

[0001] The present invention relates to the technical field of signal transmission, and in particular to a fusion-free quick-connect box used in a signal transmission system. Background Art

[0002] In the existing signal transmission system, with the development of modern optical communication technology, optical communication connections are widely used, especially the fusion-free technology has brought great convenience to optical communication connections. The existing fusion-free technology requires installing a male head and a female head on the two connected optical cables respectively, and completing the contact of the end faces of the two optical cables by adapting the structures of the male head and the female head. However, this puts high demands on the adaptability of the male head and the female head. Once the processing accuracy of the male head or the female head is insufficient and there is a deviation, it will greatly affect the adaptability of the two, resulting in problems such as no contact or poor contact between the end faces of the two optical cables. Furthermore, the current fusion-free structure needs to be connected before being placed in the optical fiber box, and the connection cannot be completed in the optical fiber box. Summary of the invention

If so, it is determined whether the number of received feedback signals from the infrared receiver is equal to a second preset threshold value. If so, a docking signal is sent out. After receiving the docking signal, the quick-connect male head is moved toward the quick-connect female head so that one of the two elastic positioning columns away from the quick-connect female head cooperates with the positioning hole to complete the fusion-free quick-connect operation.

[0011] Furthermore, when the duration of the infrared receiver feedback signal does not reach the first preset threshold, the control drive motor is started to adjust the position of the quick-connect male connector on the bar guide rail until the controller receives the infrared receiver feedback signal again, then the control drive motor is stopped, and it is determined again whether the duration of the infrared receiver feedback signal reaches the first preset threshold.

[0012] Furthermore, when the number of received infrared receiver feedback signals is not equal to the second preset threshold, the control drive motor is started to adjust the position of the quick-connect male connector on the bar guide rail until the controller receives the infrared receiver feedback signal again, then the control drive motor is stopped, and it is determined again whether the duration of the infrared receiver feedback signal reaches the first preset threshold.

When a controller receives a signal fed back by an infrared receiver, the control drive motor is stopped, and it is determined whether the duration of the feedback signal from the infrared receiver reaches a first preset threshold value. If so, it indicates that a quick-connect female head is detected and is in an aligned state. At this time, it is further determined whether the received infrared Whether the number of feedback signals from the external receiver is equal to the second preset threshold value, if so, it indicates that the currently detected quick-connect female head is the target that needs to be docked, so a docking signal is sent; when the docking signal is received, the quick-connect male head is moved toward the quick-connect female head so that one of the two elastic positioning columns that is away from the quick-connect female head cooperates with the positioning hole to complete the non-welding quick-connect operation. If the number of feedback signals from the infrared receiver received is not equal to the second preset threshold value, it indicates that the currently detected quick-connect female head is not the target that needs to be docked, and the quick-connect male head is moved along the strip guide rail again until the target that needs to be docked is detected, and the non-welding quick-connect operation is completed. Using a non-welding quick-connect box for a signal transmission system provided by the present invention, a non-welding quick-connect operation can be completed inside the quick-connect box, and there is no need to ensure alignment through the adaptability of the male or female head, thereby effectively avoiding the influence caused by insufficient processing accuracy of the male or female head.

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0039] like Figure 1-Figure 16 As shown, the present invention provides a non-welding quick-connect box for use in a signal transmission system, comprising a non-welding quick-connect box body and a quick-connect male connector, a quick-connect female connector, a position adjustment component and a detection and identification component respectively arranged inside the non-welding quick-connect box body;

[0040] The position adjustment assembly includes a strip guide rail arranged parallel to one end of the non-welding quick-connect box body, a screw rod parallel to the strip guide rail, a driving motor connected to one end of the screw rod, and a fixing frame for installing a quick-connect male head, a slider matched with the screw rod is connected to the fixing frame, a guide groove matched with the strip guide rail is provided on the slider, and a positioning hole is provided on the side wall of the fixing frame;

[0041] The detection and identification component includes an infrared laser, an infrared receiver and a controller; the quick-connect male head includes a first fiber core located on its central axis, and more than two infrared lasers are evenly arranged around the periphery of the first fiber core, and the first fiber core is flush with an end surface of the quick-connect male head facing the quick-connect female head; two elastic positioning columns are provided on the outer side wall of the quick-connect male head, which are respectively used to switch with the positioning holes;

[0042] Two or more quick-connect female connectors are arranged in parallel and spaced apart in sequence along the other end of the non-fusion quick-connect box body; the quick-connect female connector includes a second fiber core located on its central axis, and each quick-connect female connector is provided with a different number of infrared receivers, and the positions of the infrared receivers are arranged relative to the positions of the infrared lasers, and all the infrared receivers are electrically connected to the controller;

[0043] When the quick-connect male connector is installed in the fixing frame, one of the two elastic positioning columns close to the quick-connect female connector cooperates with the positioning hole, and the distance between the first fiber core and the second fiber core is equal to the distance between the two elastic positioning columns;

[0044] The control drive motor is started, and the fixing frame is driven by the screw to move the quick-connect male head along the strip guide rail. When the controller receives the feedback signal from the infrared receiver, the control drive motor is stopped, and it is determined whether the duration of the feedback signal from the infrared receiver reaches a first preset threshold value. If so, it is determined whether the number of received feedback signals from the infrared receiver is equal to a second preset threshold value. If so, a docking signal is sent out. After receiving the docking signal, the quick-connect male head is moved toward the quick-connect female head so that one of the two elastic positioning columns away from the quick-connect female head cooperates with the positioning hole to complete the fusion-free quick-connect operation.

[0045] From the above description, it can be seen that the present invention has the following beneficial effects:

[0046] The present invention provides a non-welding quick-connect box for use in a signal transmission system, comprising a non-welding quick-connect box body and a quick-connect male head, a quick-connect female head, a position adjustment component and a detection and identification component respectively arranged inside the non-welding quick-connect box body, and through a specific structural design, a control drive motor is started, and a screw is used to drive a fixed frame to move the quick-connect male head along a strip guide rail. When a controller receives a signal fed back by an infrared receiver, the control drive motor is stopped, and it is determined whether the duration of the feedback signal from the infrared receiver reaches a first preset threshold value. If so, it indicates that a quick-connect female head is detected and is in an aligned state. At this time, it is further determined whether the received infrared Whether the number of feedback signals from the external receiver is equal to the second preset threshold value, if so, it indicates that the currently detected quick-connect female head is the target that needs to be docked, so a docking signal is sent; when the docking signal is received, the quick-connect male head is moved toward the quick-connect female head so that one of the two elastic positioning columns that is away from the quick-connect female head cooperates with the positioning hole to complete the non-welding quick-connect operation. If the number of feedback signals from the infrared receiver received is not equal to the second preset threshold value, it indicates that the currently detected quick-connect female head is not the target that needs to be docked, and the quick-connect male head is moved along the strip guide rail again until the target that needs to be docked is detected, and the non-welding quick-connect operation is completed. Using a non-welding quick-connect box for a signal transmission system provided by the present invention, a non-welding quick-connect operation can be completed inside the quick-connect box, and there is no need to ensure alignment through the adaptability of the male or female head, thereby effectively avoiding the influence caused by insufficient processing accuracy of the male or female head. Furthermore, this scheme is suitable for one quick-connect male head to adapt to multiple quick-connect female heads, thereby improving application flexibility.

[0047] Furthermore, when the duration of the infrared receiver feedback signal does not reach the first preset threshold, the control drive motor is started to adjust the position of the quick-connect male connector on the bar guide rail until the controller receives the infrared receiver feedback signal again, then the control drive motor is stopped, and it is determined again whether the duration of the infrared receiver feedback signal reaches the first preset threshold.

[0048] From the above description, it can be known that, through the above method, when the duration of the feedback signal of the infrared receiver does not reach the first preset threshold value, the surface quick-connect male head and the quick-connect female head are not aligned, that is, the axis of the first fiber core of the quick-connect male head and the axis of the second fiber core of the quick-connect female head are not in the same straight line. Therefore, by controlling the start of the drive motor, the position of the quick-connect male head on the strip guide rail is adjusted so that the axis of the first fiber core of the quick-connect male head and the axis of the second fiber core of the quick-connect female head are in the same straight line, and the alignment operation of the quick-connect male head and the quick-connect female head is completed before entering the next step of judgment.

[0049] Furthermore, when the number of received infrared receiver feedback signals is not equal to the second preset threshold, the control drive motor is started to adjust the position of the quick-connect male connector on the bar guide rail until the controller receives the infrared receiver feedback signal again, then the control drive motor is stopped, and it is determined again whether the duration of the infrared receiver feedback signal reaches the first preset threshold. If so, it is determined again whether the number of received infrared receiver feedback signals is equal to the second preset threshold.

[0050] From the above description, it can be seen that through the above method, that is, the number of infrared receiver feedback signals received is not equal to the second preset threshold, it indicates that the currently detected quick-connect female connector is not the target that needs to be docked, and the quick-connect male connector is moved along the strip guide rail again until the target that needs to be docked is detected, and the fusion-free quick-connect operation is completed.

[0051] Furthermore, the number of the infrared lasers is four, and the four infrared lasers are distributed on the quick-connect male connector at four vertex positions of a square, and the axis of the first fiber core on the quick-connect male connector is located at the center position of the square;

[0052] The number of the quick-connect female connectors is four, and the numbers of the infrared receivers configured on the four quick-connect female connectors are one, two, three and four respectively.

[0053] From the above description, it can be seen that, through the above method, four infrared lasers are configured, and the number of infrared receivers configured on the four quick-connect female heads is one, two, three and four respectively. The number of feedback signals received from the infrared receivers can be used to determine which quick-connect female head is currently aligned. This process is performed inside the quick-connect box and cannot be known to the outside world. In this way, the situation inside the quick-connect box can be known.

[0054] Furthermore, an accommodating groove for accommodating infrared lasers is provided on one end surface of the quick-connect male connector facing the quick-connect female connector. The number of the accommodating grooves is equal to the number of infrared lasers and is arranged in one-to-one correspondence. The notch of the accommodating groove faces the quick-connect female connector.

[0055] It can be seen from the above description that the infrared laser is assembled in the above manner without protruding from the notch of the receiving groove, thereby avoiding interference with the docking of the fiber core.

[0056] Furthermore, an indicator light is provided on the outer side wall of the non-fusion quick-connect box body, the indicator light is electrically connected to the controller, and the indicator light is used to display the docking signal.

[0057] From the above description, it can be seen that through the above method, whether the docking operation can be performed can be characterized according to the state displayed by the indicator light, so that the internal situation can be intuitively known from the outside.

[0058] Furthermore, the first preset threshold value ranges from 3 seconds to 10 seconds.

[0059] From the above description, it can be seen that the above parameters can be used to determine whether alignment is achieved.

[0060] Furthermore, one end of the weld-free quick-connect box body is provided with an opening for the quick-connect male head to extend out and a roller shutter structure arranged at the opening, and the roller shutter structure includes two rotating shafts respectively arranged on both sides of one end of the weld-free quick-connect box body and two roller shutters respectively wound around the rotating shafts.

[0061] From the above description, it can be seen that through the above structural design, while satisfying the movement of the quick-connect male head, it also plays the role of dust prevention and sealing.

[0067] The strip guide rail 4 is parallel to one end of the long side of the corresponding rectangular parallelepiped of the non-welding quick-connect box body 1, the vertical cross-section of the fixed frame 7 is square, a slider 71 matching with the screw rod is connected to the bottom of the fixed frame 7, a guide groove 72 matching with the strip guide rail is provided below the slider 71, and a positioning hole 73 is provided on the side wall of the fixed frame 7;

[0068] The detection and identification component includes an infrared laser 8, an infrared receiver 9 and a controller; wherein the infrared laser, the infrared receiver and the controller all adopt existing electronic devices, and the infrared laser and the infrared receiver are a set of compatible products.

[0069] The quick-connect male connector 2 includes a first fiber core 21 located on its central axis, and more than two infrared lasers 8 are evenly arranged around the periphery of the first fiber core 21. In this embodiment, the number of the infrared lasers is four, and the four infrared lasers are distributed on the quick-connect male connector at four vertex positions of a square, and the axis of the first fiber core on the quick-connect male connector is located at the center position of the square; the first fiber core is flush with an end surface of the quick-connect male connector facing the quick-connect female connector;

[0070] Two elastic positioning columns 22 are provided on the outer side wall of the quick-connect male connector 2 for respectively switching with the positioning holes;

[0072] In this embodiment, the number of the quick-connect female connectors 3 is four, and the number of infrared receivers configured on the four quick-connect female connectors 3 is one, two, three, and four, respectively. In the above manner, four infrared lasers are configured, and the number of infrared receivers configured on the four quick-connect female connectors is one, two, three, and four, respectively. The number of feedback signals received from the infrared receivers can be used to determine which quick-connect female connector is currently aligned. This process is performed inside the quick-connect box and cannot be known to the outside world. In this way, the situation inside the quick-connect box can be known.

[0073] When the quick-connect male connector is installed in the fixing frame, one of the two elastic positioning columns close to the quick-connect female connector cooperates with the positioning hole, and the distance between the first fiber core and the second fiber core is equal to the distance between the two elastic positioning columns;

[0074] The control drive motor 6 is started, and the screw 5 drives the fixing frame 7 to move the quick-connect male connector 2 along the strip guide 4. When the controller receives the feedback signal from the infrared receiver, the control drive motor 6 is stopped, and it is determined whether the duration of the feedback signal from the infrared receiver reaches a first preset threshold value; in this embodiment, the range of the first preset threshold value is 3 seconds to 10 seconds, preferably 3 seconds.

[0075] If the duration of the infrared receiver feedback signal reaches the first preset threshold, it is determined whether the number of received infrared receiver feedback signals is equal to the second preset threshold. If so, a docking signal is issued; after receiving the docking signal, the quick-connect male head is moved toward the quick-connect female head so that one of the two elastic positioning columns away from the quick-connect female head cooperates with the positioning hole to complete the non-welding quick-connect operation.

[0076] In this embodiment, the controller is equipped with a timer, which is used to count the duration of the feedback signal from the infrared receiver. The controller is equipped with a judger, which is used to judge the corresponding logic instruction.

[0077] When the duration of the feedback signal from the infrared receiver does not reach the first preset threshold, the control drive motor is started to adjust the position of the quick-connect male head on the strip guide rail until the controller receives the signal from the infrared receiver again, the control drive motor is stopped, and it is judged again whether the duration of the feedback signal from the infrared receiver reaches the first preset threshold. In the above manner, when the duration of the feedback signal from the infrared receiver does not reach the first preset threshold, the surface quick-connect male head and the quick-connect female head are not aligned, that is, the axis of the first fiber core of the quick-connect male head and the axis of the second fiber core of the quick-connect female head are not in the same straight line.

The number of the receiving grooves is equal to the number of the infrared lasers and is arranged one-to-one. The notch of the receiving groove faces the quick-connect female connector.
