Description

Technical Field

[0001] The utility model relates to the field of optical terminal testing, in particular to a batch testing device for power modules of optical terminals. Background Art

[0002] As the price of optical fiber decreases, optical fiber communication becomes more and more common. Optical terminal is the terminal equipment for optical signal transmission. The main function of optical terminal is to realize the mutual conversion between optical signal and electrical signal, and to achieve the compatibility between optical signal and network electrical signal.

[0003] As the number of optical terminals increases, the maintenance workload of optical terminals also increases. During the maintenance process of optical terminals, various tests are often required. Among them, power supply testing is an important link. In the power supply testing link, it is necessary to input a fluctuating alternating voltage to the power supply of the optical terminal, and then detect whether the output is stable at the output end of its power module.

[0004] In the prior art, the testing of optical terminals is often carried out one by one, that is, each function of each optical terminal is tested one by one. Such testing requires each tester to be familiar with all the testing processes, which undoubtedly increases the cost and reduces the efficiency.

[0005] Therefore, some existing technologies attempt to split the test links and only test one test or multiple related tests at each node. Under this guidance, some existing technologies use an assembly line method to test the optical terminal and perform different types of tests at each link in the assembly line.

[0006] However, since the power function test is different from other tests, for the optical terminal, although the input end of its power module is outside, its output end is inside. Therefore, using an assembly line still requires connecting the power devices of each optical terminal one by one, and the efficiency is still not high. Utility Model Content

[0007] The purpose of the utility model is to provide a batch testing device for the power module of an optical terminal. By designing a switch array, a plurality of first electrical connection joints and a second electrical connection joint whose number is the same as that of the first electrical connection joints, batch testing of a plurality of optical terminals can be realized. Compared with a single test, the phase rate can be improved, and a fast switching mechanism is provided to improve the switching efficiency during the batch testing process.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0012] A switch array includes two first switches, second switches whose number is the same as and corresponds to the first electrical connection connectors, and third switches whose number is the same as and corresponds to the second electrical connection connectors, wherein one end of one of the first switches is connected to the positive pole of the input end of the test host, and the other end is respectively connected to the first end of each second switch, one end of another first switch is connected to the negative pole of the input end of the test host, and the other end is respectively connected to the first end of each third switch, the second end of each second switch is respectively connected to the second end of each first electrical connection connector, and the second end of each third switch is respectively connected to the second end of each second electrical connection connector.

[0013] The adjustable power supply is an AC power supply.

[0014] A fourth switch is provided between the power distributor and the power modules of each optical terminal.

[0015] The power distributor is a selection switch, the common end of which is connected to an adjustable power supply, each output end is respectively connected to the input end of a power module of each optical terminal, and one of all the output ends is selected to be connected to the common end.

[0016] The second switch and the third switch corresponding to the power module of the same optical terminal form a double-pole double-throw switch.

[0017] The first electrical connection connector and the second electrical connection connector are metal clips.

[0018] The test host is a multimeter.

[0019] The second switch and the third switch are relays.

[0020] A main circuit switch is provided between the power distributor and the adjustable power supply.

[0021] The trunk switch is a manual switch.

[0024] 2. By setting a fourth switch or selecting a selection switch for the power distributor, only one optical terminal is turned on at the same time. This can avoid affecting the life of the power module of the optical terminal on the one hand, and avoid mutual interference that leads to inaccurate test results on the other hand.

[0025] 3. The second switch and the third switch corresponding to the power module of the same optical terminal form a double-pole double-throw switch, which can improve synchronization, thereby improving test efficiency on the one hand, and reducing interference and shortening the time waiting for the signal to stabilize on the other hand.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0030] A batch testing device for an optical terminal power module 1, comprising:

[0031] Test host 2;

[0032] A power distributor, the input end of which is connected to an adjustable power supply AC, and the output end of which is respectively connected to the input end of the power module 1 of each optical terminal;

[0033] A plurality of first electrical connection connectors and a second electrical connection connector having the same number as the first electrical connection connectors, wherein the first end of each first electrical connection connector is respectively connected to the positive electrode of the output end of the power module 1 of the optical terminal, and the first end of each second electrical connection connector is respectively connected to the negative electrode of the output end of the power module 1 of the optical terminal;

[0034] A switch array includes two first switches S1, second switches S2 having the same number and one-to-one correspondence with the first electrical connection connectors, and third switches S3 having the same number and one-to-one correspondence with the second electrical connection connectors, wherein one end of one of the first switches S1 is connected to the positive pole of the input end of the test host 2, and the other end is respectively connected to the first end of each second switch S2, one end of another first switch S1 is connected to the negative pole of the input end of the test host 2, and the other end is respectively connected to the first end of each third switch S3, the second end of each second switch S2 is respectively connected to the second end of each first electrical connection connector, and the second end of each third switch S3 is respectively connected to the second end of each second electrical connection connector.

[0035] By designing a switch array, multiple first electrical connection connectors and a second electrical connection connector with the same number as the first electrical connection connectors, batch testing of multiple optical terminals can be achieved, which can improve the phase rate compared to single testing, and a fast switching mechanism is set up to improve the switching efficiency during batch testing.

[0036] Generally, the adjustable power supply AC is an AC power supply. The adjustable power supply AC can be the same as that in the prior art, and can output AC power ranging from 100 to 250V. Of course, in other embodiments, other specifications can also be used, but its output voltage range should cover the input voltage range of the power module 1 of the optical terminal, so as to achieve comprehensive testing. In addition, in some embodiments, the adjustable power supply AC can also select some models with larger rated power and more stable output.

[0037] In some embodiments of the adjustable power supply AC using the same type as in the prior art, it is generally necessary to set some means to ensure that only one input of the power module 1 is connected, so as to avoid the situation where the output voltage is inaccurate due to excessive output power. In some embodiments, such as Figure 2 As shown, a fourth switch S4 is provided between the power distributor and the power module 1 of each optical terminal. At this time, the power distributor can adopt an extension board 3, and only one fourth switch S4 is selected to be turned on at the same time; in addition, in other embodiments, the power distributor is a selection switch SS, the common end of the selection switch SS is connected to the adjustable power supply AC, and each output end is respectively connected to the input end of the power module 1 of each optical terminal, and one of all the output ends is connected to the common end.

[0038] By setting the fourth switch S4 or selecting the selection switch SS for the power distributor, only one optical terminal is turned on at the same time, which can avoid affecting the life of the power module 1 of the optical terminal on the one hand, and avoid mutual interference leading to inaccurate test results on the other hand.

[0039] In certain embodiments, such as Figure 1As shown, the second switch S2 and the third switch S3 corresponding to the power module 1 of the same optical terminal form a double-pole double-throw switch, which can improve synchronization, thereby improving test efficiency on the one hand and reducing interference and shortening the time to wait for signal stabilization on the other hand.

[0040] Generally, in some embodiments, the first electrical connection connector and the second electrical connection connector are metal clips, and the test host 2 is a multimeter. In this case, data needs to be recorded manually, and all switches are manual switches.

[0041] Of course, in other embodiments, the second switch S2 and the third switch S3 are relays. At the same time, the test host 2 can use a dedicated embedded computing device to control the on and off of each relay to achieve automatic control.

[0042] Furthermore, in some embodiments, a mains switch is provided between the power distributor and the adjustable power source AC, so that the mains switch can be cut off when not needed.

[0043] In addition, the present application also provides a testing method for the above-mentioned testing device, comprising:

[0044] Step S1: while keeping all the first switches S1, the second switches S2 and the third switches S3 disconnected, determining the optical terminal to be tested;

[0045] Step S2: Turn on the second switch S2 and the third switch S3 corresponding to the optical terminal to be tested;

[0046] Step S3: After the second switch S2 and the third switch S3 are turned on, the two first switches S1 are turned on;

[0047] Step S4: When the first switch S1 is turned on, the test of the power module 1 of the optical terminal to be tested is completed;

[0048] Step S5: After disconnecting the two first switches S1, disconnect the second switch S2 and the third switch S3;

[0049] Step S6: Determine whether the test of all optical terminals is completed. If yes, the test is completed. Otherwise, select the next optical terminal that has not been tested and return to step S2.

[0050] When the second switch and the third switch are in operation, the first switch always remains in an open state, thereby reducing costs.
