DETAILED DESCRIPTION

[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0037] On the first aspect, an embodiment of the present invention provides a universal cable network instantaneous break test device. Aiming at the characteristics of the cable network with many lines, complex and changeable interfaces, and short test intervals, the device of the present invention flexibly combines adapters, adapter tooling, and short stubs to connect all the lines of the cable network to be tested into one test line, and uses a tester to monitor the test line. Since the adapter tooling and short stubs are made of simple materials, low cost, and unified interfaces, the adapter cable is a universal tooling for cable network performance testing and can be shared, and the tester is a conventional testing instrument. The device of the present invention can be flexibly combined according to the characteristics of the cable network interface connector, can perform instantaneous break tests in dynamic environments of cable networks of different types, is simple and convenient to operate, has the characteristics of strong versatility and convenient tooling use, and can well complete instantaneous break tests in dynamic environments of cable networks.

[0038] like Figure 1 As shown, the embodiment of the present invention provides a universal cable network instantaneous interruption test device, including: a cable network to be tested 101, a transfer line (not shown in the figure), a transfer tool 102, a short stub 103, and a tester (including a DC regulated power supply 104 and an oscilloscope 105). This embodiment has two different specifications of transfer tools 102, namely a first transfer tool 102A and a second transfer tool 102B.

[0039] The cable network 101 to be tested is in a dynamic environment, such as a dynamic environment of vibration, impact, emission, etc.

[0040] The cable network 101 to be tested includes N adapters of different models, each of which has M contacts in use; N≥2, M≥1 and are integers. The M contacts of each connector are connected to some of the M contacts of other plugs; and / or some of the M contacts inside each connector are connected.

[0041] by Figure 2 Take the cable network 101 to be tested in the example, which includes 4 adapters, namely: adapter S, adapter P, adapter Y, adapter Z. Each contact in the adapter has its own number. For example, adapter S has 40 contacts, and the contacts in use are: S1~S8, S19~S22, S25, S26. Adapter P has 24 contacts, and the contacts in use are: P1~P8, P10, P12, P19, P20. Adapter Y has 4 contacts, and the contacts in use are: Y1~Y4. Adapter Z has 4 contacts, and the contacts in use are: Z1~Z4. The connection status of the contacts of each connector is shown in Figure 2 It has been marked and will not be repeated here.

[0042] In order to perform instantaneous disconnection detection on the cable network 101 to be tested, the M contacts in use in the N adapters are led out separately through adapter wires, and one connection wire is led out from one node. In practical applications, the connection wire is exemplified as a connection cable.

[0043] The adapter 102 includes an adapter panel 1021 and a plurality of jacks 1022. Figure 3 , is a schematic diagram of the structure of the adapter tooling, and a plurality of jacks 1022 are arranged on the tooling panel 1021. Of course, the adapter tooling 102 is also provided with a universal adapter socket 1023, which can be arranged on the side of the adapter tooling 102. The universal adapter socket 1023 will be introduced later and will not be described here.

[0044] When the connector is connected, each jack is connected to a transfer line to transfer the M contacts in use in the N connectors to the transfer tooling 102. The transfer line leads each contact in the adapter separately, the transfer line is connected to the transfer tooling 102, and all the contacts are led to the tooling panel 1021 through the socket. If the number of interface connectors is small, the commonly used connector interfaces can be combined and connected to the same transfer tooling 102, and all the contacts are connected in series into one line according to the wiring principle of the cable network.

[0045] Each socket in the adapter 102 has a number. The M contacts in use in the N connectors are plugged into the corresponding sockets in the adapter according to the numbers. In order to intuitively see the plugging status of the connectors, the connector numbers are used in the adapter to illustrate.

[0046] In one embodiment, if the number of jacks in the adapter 102 is greater than or equal to the total number of contacts in use in the N connectors, the N connectors are connected to the same adapter 102. That is, all contacts of the N connectors are connected to the same adapter 102, and the same adapter 102 can be connected to connectors of different models.

[0047] In one embodiment, if the number of jacks in the adapter 102 is less than the total number of contacts in use in the N connectors, the N connectors are connected to different adapters 102. Figure 4A , is a schematic diagram of the connection between the connector and one of the transfer fixtures. The M contacts in use in the connector S are all connected to the first transfer fixture 102A. Figure 4B , is another schematic diagram of the connector and the adapter. The contacts in the connector P, the connector Y, and the connector Z are connected to the second adapter 102B. It is worth noting that the universal adapter socket 1023 in the second adapter 102B can be respectively adapted and connected to the connector P, the connector Y, and the connector Z.

[0048] The stub 103 is connected to some of the contacts in the adapter 102, so that the M contacts in use in the N connectors are connected in series to form one test line. Specifically, according to the contact connection conditions of the N adapters, some of the contacts in the adapter are short-circuited using the stub 103, so that the M contacts in use in the N connectors are connected in series to form one test line.

[0049] See also Figure 5 , which is a schematic diagram of a short stub. The two ends of the short stub 103 are banana plugs 1031 adapted to the jack, respectively, for short-circuiting two contacts.

[0050] Further, according to Figure 2 The connection of the contacts of the N adapters in the first adapter 102A and the second adapter 102B is checked by using short-circuit wires, and the lines of the first adapter 102A and the second adapter 102B are connected in series into one test line using short stubs. Specifically, in the first adapter 102A, short stubs are used to short-circuit: S7-S8, S25-S26; in the second adapter 102B, short stubs are used to short-circuit P2-P4, P3-P5, P6-P7, P8-P19, P10-P20, P12-Y1, Y2-Y3, Z1-Z2, Z3-Z4, thereby connecting the cable network 101 to be tested into one test line, with the starting point of the test line being P1 and the end point being Y4.

[0051] See also Figure 6A-6B , is a connection diagram of the test circuit.

[0052] The tester is connected to the starting point and the end point of the test line respectively to perform a momentary interruption detection on the cable network 101 to be tested. Specifically, the tester includes: a DC regulated power supply 104 and an oscilloscope 105. The DC regulated power supply 104 and the oscilloscope 105 are connected in series. One end of the DC regulated power supply 104 is connected to the starting point of the test line, and one end of the oscilloscope 105 is connected to the end point of the test line.

[0053] The DC stabilized power supply 104 is used to provide different voltages to the test circuit, and the oscilloscope 105 is used to perform instantaneous disconnection detection on the cable network 101 to be tested when different voltages are provided to the test circuit. The DC stabilized power supply 104 and the oscilloscope 105 can cooperate to complete the instantaneous disconnection test of the cable network. When the cable network 101 to be tested is in a dynamic environment, such as vibration, impact, emission and other dynamic conditions, if there are problems with the cable's conductivity, cable joints, solder joint connections, etc., an instantaneous disconnection reaction will occur, and this abnormal situation can be monitored by observing the waveform in the oscilloscope 105.

[0054] The reading frequency of the oscilloscope 105 is set to 1 μs, and the voltage change track of the oscilloscope 105 can capture the instantaneous disconnection of the cable network in a dynamic environment. The detection interval is 1 μs, so that the test interval of the present invention reaches the μs level.

[0055] The above is the technical solution of the present invention, which flexibly combines the adapter wire, the adapter tooling and the short-cut wire, transfers the connectors of different types in the cable network to be tested in the adapter tooling, connects the currently used lines of the cable network to be tested into one test line, and uses a tester to perform momentary break detection, thereby capturing the momentary break of the cable network under a dynamic environment.

[0056] In one embodiment, see Figure 7 This embodiment further includes: a test adapter cable 106. If the model of the adapter in the cable network 101 to be tested is compatible with the test adapter cable 106, it can also be transferred to the adapter tooling 102 through the test adapter cable 106.

[0057] At this time, the adapter tool 102 is provided with a universal adapter socket 1023, which is used to replace the corresponding socket on the adapter tool 102 to connect the corresponding adapter in the cable network 101 to be tested. It is worth noting that at least one universal adapter socket 1023 is provided on the adapter tool. Fig. 8A , is a schematic diagram of the contact connection after the connector S is plugged into the first adapter. The first adapter 102A is provided with a universal adapter socket for plugging the connector S. Figure 8B, is a schematic diagram of the connection of the contacts of connector P, connector Y, and connector Z after being plugged into the second transfer tooling. The second transfer tooling 102B is provided with three universal transfer sockets 1023, which are respectively used to plug connector P, connector Y, and connector Z. It is worth noting that if there is a connector (including contacts: x1, x2, x3, x4), the transfer socket 1023 can also be used for connection.

[0058] like Figure 7 As shown, one end of the test adapter cable 106 is a test adapter socket 1061 , and the other end is a universal plug 1062 ; wherein the universal plug 1062 is plugged into the universal adapter socket 1023 to connect to the adapter tooling 102 .

[0059] If the test adapter socket 1061 in the test adapter cable 106 is compatible with the target adapter in the N connectors, the target adapter is transferred in the adapter tool 102 via the test adapter cable 106 .

[0060] It is worth noting that the test adapter cable 106 also has different models and can be used in different situations.

[0061] The above is another technical solution of the present invention. If the adapter in the cable network to be tested can be adapted to the test adapter cable, the test adapter cable can be used to transfer connectors of different models in the adapter tooling, and the lines in use of the cable network to be tested can be connected in series into one test line. A tester can be used to perform momentary break detection to capture the momentary break of the cable network under a dynamic environment.
