[0002] The shear force test of coaxial optical communication components is to ensure that the components can withstand certain mechanical stress during installation and operation without causing performance degradation or damage. This test is usually used to evaluate the mechanical strength of components such as optical fiber connectors and jumpers.

[0003] The tensile test of optical fiber connectors is generally carried out using an optical return loss tester. During the test, the optical fiber connector to be tested is first connected to the optical transmission circuit, and then a certain tensile force is applied to the line connected to one side of the optical fiber connector. It is observed whether the reading of the optical return loss tester exceeds the set range within the specified time, so as to determine the tensile performance of the optical fiber connector. However, the current test operation requires a long time to test. During this test time, the operator cannot perform other operations on the equipment and can only wait until the test of the optical fiber connector is completed before continuing to install and test another optical fiber connector that needs to be tested, resulting in a lot of time waste and is not conducive to improving the test speed.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model discloses an optical communication device testing device, comprising an optical return loss tester 1 and a detection cable 2 detachably arranged on the optical return loss tester 1, the detection cable 2 consists of a first cable 21 and a second cable 22, one end of each of the first cable 21 and the second cable 22 is connected to the optical return loss tester 1, a fiber optic connector is detachably arranged between the end of the first cable 21 away from the optical return loss tester 1 and the end of the second cable 22 away from the optical return loss tester 1, the number of optical return loss testers 1 is two, an adjustment table 3 is arranged between the two optical return loss testers 1, a clamping bracket 4 for limiting the movement of the end of the first cable 21 away from the optical return loss tester 1 is arranged on the adjustment table 3, and a pressure mechanism 5 capable of switching to apply a downward pulling force to two different second cables 22 is also rotatably arranged on the adjustment table 3.

[0020] The utility model provides two groups of test devices for detecting optical fiber connectors. When the optical fiber connector on one group of test devices is subjected to the pressure of the pressure mechanism 5 for tensile test, the operator can complete the installation preparation operation of the optical fiber connector to be tested at the other group of test devices. After the optical fiber connector in the detection state is detected, the pressure direction of the pressure mechanism 5 can be switched, so that the detection state of another optical fiber connector can be quickly entered. By making full use of the waiting time, the purpose of improving the detection efficiency of the optical fiber connector is achieved.

[0021] In one embodiment, the control console 3 is composed of a panel 31 and two side panels 32 arranged at the bottom of the panel 31. A positioning hole is opened on the panel 31 for the second cable 22 to pass through. The positioning hole is located directly below the end of the first cable 21 away from the optical return loss tester 1.

[0022] This design allows the second cable 22 to pass through the positioning hole and connect to the optical fiber connector, ensuring that the pulling direction of the optical fiber connector during testing points downward, avoiding bending of the optical fiber connector due to tension offset, which affects the accuracy of the tensile performance test.

[0023] In one embodiment, the pressure mechanism 5 includes a rotating rod 51 rotatably arranged on the side plate 32 and a pressure ring 52 fixedly arranged on the second cable 22, the rotating rod 51 is located between the two second cables 22, the pressure ring 52 is located below the positioning hole, and a pressure rod 53 is arranged on the rotating rod 51, which can rotate with the rotating rod 51 and apply downward pressure to the pressure ring 52 after contacting the pressure ring 52.

[0024] This design allows the inspector to drive the pressure rod 53 to rotate to the side of a different pressure ring 52 by simply rotating the rotating rod 51. When the pressure rod 53 contacts the pressure ring 52, the inclined pressure rod 53 provides downward pressure on the pressure ring 52, making the adjustment of the entire pressure mechanism 5 convenient and quick.

[0025] In a specific implementation, an assembly hole for placing a counterweight is provided in the middle of the pressure rod 53. By replacing counterweights of different gravities, the pressure rod 53 can apply different magnitudes of downward pulling forces to the pressure ring 52, thereby meeting different test standards and test requirements.

[0026] In one embodiment, a limiting ring 6 is fixedly provided on the second cable 22 and is located above the positioning hole. The outer diameter of the limiting ring 6 is not less than the aperture of the positioning hole.

[0027] With this design, the limiting ring 6 is used to prevent the second cable 22 from escaping from the positioning hole, thereby facilitating operators to quickly find the connection end between the second cable 22 and the optical fiber connector, further improving detection efficiency.

[0028] In one embodiment, the panel 31 is provided with an auxiliary testing mechanism 7 capable of suspending the upper limit ring 6 of the corresponding second cable 22 when the pressure ring 52 is under pressure; the auxiliary testing mechanism 7 includes a gear 71 rotatably arranged on the panel 31, a driven rack 72 meshing with the gear 71 and capable of moving toward and away from the limit ring 6 when the gear 71 rotates is arranged on the top of the gear 71, the driven rack 72 is located between the two limit rings 6, and both ends of the driven rack 72 are provided with C-shaped rings 73 that can be sleeved on the second cable 22, and the inner diameter of the C-shaped ring 73 is not greater than the outer diameter of the limit ring 6, and an active rack 74 meshing with the gear 71 is arranged at the bottom of the gear 71, and two shifting blocks 75 that move synchronously with the active rack 74 are arranged on the active rack 74, and the shifting blocks 75 are slidably arranged at the bottom of the panel 31;

[0029] When the pressure ring 52 is under pressure, the limiting ring 6 on the corresponding second cable 22 is not located directly above the C-shaped ring 73 , and the shifting block 75 away from the corresponding second cable 22 is located within the rotation range of the pressure rod 53 .

[0030] With this design, when the pressure rod 53 rotates from the side of the tested piece to the side of the to-be-tested piece, it pushes the shifting block 75 within the rotation range of the pressure rod 53, thereby driving the active rack 74 to move toward the side of the to-be-tested piece. Under the transmission of the gear 71, the driven rack 72 drives the C-shaped ring 73 to move away from the to-be-tested piece, so that the C-shaped ring 73 under the to-be-tested piece is removed from under the corresponding limiting ring 6, so that the corresponding limiting ring 6 is in a suspended state, ensuring that the limiting ring 6 will not contact the panel 31 and affect the pulling force during the test, and the C-shaped ring 73 under the tested piece is moved to just below the corresponding limiting ring 6 to lift the limiting ring 6, so that the optical fiber connector can be in a lifting and supporting state after the to-be-tested piece replaces the tested piece, and the performance of the optical fiber connector in this state can be tested.

[0031] It should be noted that the pressure rod 53 rotates and pushes the shifting block 75 to move a certain distance before separating from the shifting block 75 and then contacting the pressure ring 52 again.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] In addition, "plurality" means two or more.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
