Description

Technical Field

[0001] This utility model relates to an automatic insertion and removal fixture for testing optical fibers in power system protection devices, and particularly to an automatic insertion and removal fixture for testing optical fibers in power system protection and control cabinets. Background Technology

[0002] Currently, domestic manufacturers test fiber optic boards in power systems by manually inserting the optical fibers one by one.

[0003] Current technologies rely on manual insertion and removal of optical fibers for testing. This method is prone to human contact with the fiber optic connectors, leading to fiber contamination and low test pass rates. Furthermore, manual testing is far less efficient than automated testing using robots and test cabinets. Using ordinary optical fibers directly in a test cabinet for automated testing can easily result in fiber misalignment due to hardware errors, preventing accurate insertion into the fiber optic ports on the circuit board. Utility Model Content

[0004] The purpose of this invention is to provide an automatic fiber optic testing fixture for power system protection devices, enabling integrated insertion and removal of fiber optic cables during automatic testing, thereby improving the efficiency of board testing.

[0005] To achieve the above objectives, the solution of the present invention is:

[0006] An automatic insertion and removal fixture for testing optical fibers in a power system protection device includes a clamping assembly and a locking mechanism. The clamping assembly has several clamping holes for accommodating several locking mechanisms. The locking mechanism has locking holes for passing through optical fibers.

[0007] The aforementioned clamping assembly includes an upper clamping member and a lower clamping member. The upper clamping member and the lower clamping member are respectively provided with a number of grooves at corresponding positions. When the upper clamping member and the lower clamping member are placed opposite each other, the groove portion forms a clamping hole.

[0008] The locking mechanism has two through ends, with its head extending outward to form a first protrusion; the tail end of the locking mechanism is fitted with a fixing part, the outer diameter of which is larger than the outer diameter of the locking mechanism, and the fixing part has a second protrusion on the side facing the first protrusion; the opposite sides of the first protrusion and the second protrusion are respectively fixed to the two ends of the spring.

[0009] The aforementioned fixing part includes a positioning ring and a limiting piece. The limiting piece is sleeved and fixed to the tail end of the locking mechanism, while the positioning ring is sleeved on the locking mechanism and can move relative to the locking mechanism. The positioning ring is located between the limiting piece and the first boss of the locking mechanism. One end of the spring is fixed to the first boss, and the other end of the spring is fixed to the side of the positioning ring.

[0010] The locking mechanism described above has an expansion joint along the axial direction at its head end.

[0011] The beneficial effects of this utility model after adopting the above solution are:

[0012] (1) This utility model adopts a modular structure design, which solves the problems of difficult maintenance and replacement of testing fixtures;

[0013] (2) This utility model innovatively incorporates a spring structure into the optical fiber testing fixture, enabling the optical fiber to be adaptively inserted into the optical fiber port of the board under test without manual assistance, thereby effectively avoiding interference from hardware error factors.

[0014] (3) This utility model meets the testing requirements of fiber optic boards in power systems, and can realize automated and rapid insertion and removal of fiber optic test fixtures, greatly improving the board testing efficiency, while eliminating the problem of fiber optic contamination under manual intervention.

[0020] The technical solution and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, this utility model provides an automatic insertion and removal fixture for testing optical fibers in power system protection devices, including a clamping assembly 4 and a locking mechanism 2, for inserting the optical fiber 1 into the optical fiber interface, which will be described in detail below.

[0022] The clamping assembly 4 is provided with several clamping holes, which are used to fix several locking mechanisms 3 respectively. In this embodiment, the clamping assembly 4 includes an upper clamping member 41 and a lower clamping member 42. Several grooves are respectively opened at corresponding positions of the upper clamping member 41 and the lower clamping member 42. When the upper clamping member 41 and the lower clamping member 42 are opposite to each other, the groove portion forms a clamping hole.

[0023] The locking mechanism 2 is used to fix the optical fiber 1. It is provided with a locking hole for the optical fiber 1 to pass through. The optical fiber head of the optical fiber 1 is inserted through the tail end of the locking mechanism 2 and extends out from the head end of the locking mechanism 2.

[0024] In use, the required optical fiber 1 is passed through the locking mechanism 2, which fixes the optical fiber 1. Then, the locking mechanism 2 is placed in the corresponding clamping hole of the clamping assembly 4. The upper clamping member 41 and the lower clamping member 42 are locked together to fix the locking mechanism 2. Then, the clamping assembly 4 is moved by a cylinder to insert the optical fiber 1 into the optical fiber interface, or the optical fiber 1 inserted into the optical fiber interface can be pulled out. The multiple clamping holes of the clamping assembly 4 can realize the insertion and removal control of multiple optical fiber 1. Through the modular structure design, it is not only convenient to disassemble and maintain, but also realizes the integrated insertion and removal of test optical fiber in automatic test mode. During the test, there is no need to manually intervene to adjust the position of the optical fiber, accurately inserting it into the optical fiber interface, preventing optical fiber deviation, and reducing the maintenance and calibration time in automatic test mode.

[0025] In a preferred embodiment of this invention, the optical fiber head can be adaptively adjusted. The locking mechanism 2 is designed as a T-shaped cylindrical structure with both ends extending through it. A first protrusion extends outward from one end (the head end) corresponding to the optical fiber head. It also includes a fixing part sleeved on the tail end of the locking mechanism 2. The outer diameter of the fixing part is larger than that of the locking mechanism 2, allowing them to move relative to each other. A second protrusion is formed on the side of the fixing part facing the first protrusion. A spring 3 is sleeved on the outside of the locking mechanism 2, with both ends fixed to the first and second protrusions respectively. This allows for elastic adjustment of the position of the first and second protrusions. The distance between them; the fixing part is located in the clamping hole of the clamping assembly 4, the clamping assembly 4 clamps and fixes the fixing part, and the head end of the locking mechanism 2 can extend out of the clamping assembly 4. When the fiber head 1 encounters resistance, it pushes the locking mechanism 2 to move backward and compresses the spring 3. At the same time, the spring 3 can also shake to a certain extent to better adapt to the movement of the fiber head 1. When the fiber head 1 is inserted into the fiber interface of the board, due to the error between the fiber line 1 and the fiber interface of the board, the spring 3 will swing freely due to the resistance and adaptively adjust to the best position, so as to quickly insert the fiber line into the fiber interface of the board.

[0026] In a preferred embodiment of this utility model, the fixing part includes a positioning ring 6 and a limiting piece 7. The limiting piece 7 is sleeved and fixed to the tail end of the locking mechanism 2, while the positioning ring 6 is sleeved on the locking mechanism 2 and can move relative to the locking mechanism 2. The positioning ring 6 is located between the limiting piece 7 and the first boss of the locking mechanism 2. The positioning ring 6 serves as the second boss due to its thickness. One end of the spring 3 is fixed to the first boss, and the other end of the spring 3 is fixed to the side of the positioning ring 6. The positioning ring 6 is fixed in the clamping hole by the clamping assembly 4. When the spring 3 extends or retracts, the limiting piece 7 limits the positioning ring 6. The limiting piece 7 is made of a hard material.

[0027] In a preferred embodiment of this utility model, in order to facilitate the insertion or removal of the optical fiber head 1 from the locking mechanism 2, the head end of the locking mechanism 2 is provided with an expansion joint of a certain length along the axial direction, and a fixing hole is provided along the radial direction at the head end. When the optical fiber head 1 passes through the locking mechanism 2, the screw 5 can be inserted into the fixing hole to lock the head end of the locking mechanism 2, thereby tightly fixing the optical fiber head 1 to the locking mechanism 2. When it is necessary to remove the optical fiber head 1, the screw 5 can be removed first, and the larger space formed by the expansion joint can be used to easily remove the optical fiber head 1 from the locking mechanism 2.

[0028] Through the above implementation process, integrated insertion and removal of fiber optic cables can be achieved in the automatic testing state of fiber optic interface cards. During testing, no manual intervention is required to adjust the fiber optic position; the fiber optic interface is precisely inserted, reducing maintenance and calibration time in automatic testing. This utility model technology meets the testing needs of fiber optic interface cards in power systems, enabling automated and rapid insertion and removal of fixtures, improving board testing efficiency, and eliminating fiber optic contamination problems caused by manual intervention.

[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
