Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a PON equipment quick testing fixture. Background Art

[0002] PON means that (in the optical distribution network) there is no electronic device or electronic power supply. ODN is composed entirely of passive devices such as optical splitters, and does not require expensive active electronic devices. PON equipment needs to be tested after production to ensure product quality. During testing, a fixture is required to hold the PON equipment. However, the existing fixture structure is relatively simple and has the following shortcomings when used:

[0003] 1. Many fixtures can only hold PON equipment of one specification, and their applicability is low.

[0004] 2. When testing, power cables, network cables and other connecting cables are usually connected and unplugged manually one by one. When testing multiple PON devices, it takes a lot of time and is inefficient.

[0005] Therefore, we propose a PON equipment fast test fixture. Utility Model Content

[0006] The utility model aims to solve the problems in the prior art that many fixtures can only clamp PON devices of one specification, have low applicability, and when testing, usually manually connect and unplug power cables, network cables and other connecting cables one by one. When testing multiple PON devices, it takes a lot of time and has low efficiency. A PON device quick test fixture is proposed to solve the problems that many fixtures in the prior art can only clamp PON devices of one specification, have low applicability, and when testing, usually manually connect and unplug power cables, network cables and other connecting cables one by one. When testing multiple PON devices, it takes a lot of time and has low efficiency.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A workbench, wherein a rectangular groove is provided on the surface of the workbench, two symmetrically arranged slides are slidably connected in the rectangular groove, first clamping blocks and guide rails are fixedly provided on the surfaces of the two slides, second clamping blocks are slidably connected on the surfaces of the two guide rails, grooves are provided on the inner walls of the first clamping block and the second clamping block, first spring sheets are fixedly provided in the plurality of grooves, and the first clamping block and the second clamping block cooperate with the first spring sheet to clamp the PON device;

[0010] It also includes two guide plates fixed on the surface of the workbench, a slide seat is slidably connected between the two guide plates, a plurality of through slots are opened on one side of the slide seat, and the plurality of through slots respectively correspond to the plurality of interfaces on the PON device;

[0011] An adjustment mechanism, the adjustment mechanism is arranged on the surface of the workbench and is used to adjust the positions of the first clamping block and the second clamping block;

[0012] A plurality of clamping mechanisms are respectively arranged in a plurality of through slots for clamping connecting wires such as network cables and power cables.

[0013] In a possible design, the adjustment mechanism includes a bidirectional screw and a mounting seat, the bidirectional screw rotates and passes through one side of the rectangular groove, the bidirectional screw is threaded through the two slides respectively, the mounting seat is fixed on the surface of the workbench, an adjustment block is slidably connected inside the mounting seat, a first screw rotates and passes through the inner walls on both sides of the mounting seat, the first screw thread passes through the adjustment block, adjustment rods are fixed on both sides of the adjustment block, the outer walls of the two adjustment rods are slidably connected with connecting rods, and the two connecting rods are respectively fixed to the two second clamping blocks.

[0014] In a possible design, two symmetrically arranged positioning seats are fixedly provided on the surface of the workbench, and two adjustment rods are slidably connected to the two positioning seats respectively for positioning the adjustment rods.

[0015] In a possible design, the clamping mechanism includes an upper clamping block and a lower clamping block, both of which are slidably connected in the through groove, a second screw rod is threaded through the surface of the sliding seat, and the second screw rod is rotatably connected to the upper clamping block.

[0016] In a possible design, two symmetrically arranged installation grooves are provided in the slide seat, and limit rods are slidably connected in the two installation grooves. Second spring plates are provided between adjacent limit rods and installation grooves, and penetrating limit grooves are provided on the surfaces of the two guide plates, and the limit rods and limit grooves are adapted to each other.

[0017] In a possible design, surfaces of the two first clamping blocks and the two second clamping blocks are both provided with guiding slopes.

[0018] In the present application, during the test, the positions of the first clamping block and the second clamping block are first adjusted according to the specifications of the PON device. During the adjustment, the bidirectional screw rod is rotated to drive the slide plate to move and then drive the first clamping block to move, thereby changing the spacing between the two first clamping blocks. At the same time, the slide plate drives the guide rail to move and then drives the second clamping block to move. The second clamping block drives the connecting rod to slide along the adjusting rod, and the spacing between the two second clamping blocks changes. When the spacing is appropriate, the bidirectional screw rod is stopped from being rotated, and then the first screw rod is rotated to drive the adjusting block to move. The adjusting block drives the adjusting rod to move and then drives the two second clamping blocks to move at the same time, thereby changing the spacing between the first clamping block and the second clamping block. When the spacing is appropriate, the first screw rod is stopped from being rotated, and then the PON device is placed between the first clamping block and the second clamping block. With the cooperation of the first spring piece, the PON device is limited, and then the slide of the corresponding model is placed between the two guide plates, and then the network cable, power cable and other connecting cables are placed between the corresponding upper clamp block and the lower clamp block, and then the second screw is turned to drive the upper clamp block to move, and then the network cable, power cable and other connecting cables are compressed, and then the limit rod is pressed down and the slide is pushed. When the slide is against the guide plate, the network cable, power cable and other connecting cables are connected to the interface of the PON device. After releasing, the second spring piece pushes the limit rod and the limit groove to connect, and limits the slide to prevent the network cable and power cable from being separated from the interface, and then the PON device can be tested. After the test is completed, the network cable and power cable can be quickly unplugged, and then the PON device can be quickly replaced for testing again.
