Description

Technical Field

[0001] This application belongs to the field of cable continuity testing, and particularly relates to a cable continuity testing device and system. Background Technology

[0002] After a product cable is newly manufactured or damaged during use, a continuity test is required. It is worth noting that currently used product cables are generally quite long, and the connector types at both ends are different.

[0003] Currently, a common practice in related technologies is for staff to use a multimeter to test the continuity of the cable. This requires two people to work together because the cable connectors are different models and the points are distributed differently. It is easy for staff to test the wrong points. Also, when the diameter of the connector at one end of the cable is very small, it is easy to cause the connector pins to come off or be damaged when using a multimeter. Utility Model Content

[0004] This application provides a cable continuity detection device and system, which can improve the efficiency and accuracy of cable continuity detection.

[0005] In a first aspect, embodiments of this application provide a cable continuity detection device, comprising:

[0006] The housing, and the display module, power module, at least one set of cable connectors and a power switch disposed on the housing;

[0007] Each set of cable connectors includes a first connector corresponding to the interface at the first end of the cable under test, and a second connector corresponding to the interface at the second end of the cable under test, wherein the first connector and the second connector are of different models; the power module is used to provide power for the continuity detection of the cable under test; the display module is used to display the continuity detection result of the cable under test; the start switch is used to control the connection and disconnection of the power module, so as to control the start and stop of the continuity detection of the cable under test.

[0008] Secondly, embodiments of this application provide a cable continuity detection system, including a power supply, a cable to be tested, and a cable continuity detection device as described in the first aspect.

[0009] The cable continuity testing device and system of this application embodiment include at least one set of cable connectors on the housing of the cable continuity testing device. Each set of cable connectors includes a first connector and a second connector of different models. The first connector corresponds to the interface at the first end of the cable under test, and the second connector corresponds to the interface at the second end of the cable under test. This allows simultaneous connection of the interfaces at both ends of the cable under test using a single set of cable connectors, improving the efficiency of cable continuity testing and avoiding potential errors that might occur when individually testing each jack at both ends of the cable using a multimeter. This also improves the accuracy of cable continuity testing. Furthermore, after the cable under test is connected to the set of cable connectors, turning on the start switch allows the display module on the housing of the continuity testing device to display the continuity test result, enabling users to intuitively observe the continuity status of the cable under test and reducing the operational difficulty of cable continuity testing.

[0021] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Terms such as "connected" or "linked" are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships, which may change accordingly when the absolute position of the described objects changes. Additionally, in the description of this application, unless otherwise stated, the term "a number" refers to two or more. The term "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0023] As described in the background section, a common practice in current related technologies is for workers to use a multimeter to test the continuity of cables. This requires two people working together, using the multimeter probes to contact the connectors at both ends of the cable to determine if there is continuity between them. However, because cable connectors have different models and different contact points, workers are prone to testing the wrong points. Furthermore, when the connector diameter at one end of the cable is very small, using a multimeter can easily cause the probes to retract or become damaged.

[0024] To address the problems in the prior art, this application provides a cable continuity testing device. By using a set of cable connectors, the interfaces at both ends of the cable to be tested can be connected simultaneously, which improves the efficiency of cable continuity testing, avoids the possible testing errors that may occur when testing each jack in the interfaces at both ends of the cable one by one with a multimeter, and improves the accuracy of cable continuity testing.

[0025] The continuity detection device for cables provided in the embodiments of this application will be described first below.

[0026] Figure 1 A schematic diagram of the structure of a first type of cable continuity detection device according to an embodiment of this application is shown. The cable continuity detection device includes: a housing, and a display module 03, a power module 06, at least one set of cable connectors, and a start switch 04 disposed on the housing;

[0027] Each set of cable connectors includes a first connector 01 corresponding to the interface at the first end of the cable under test, and a second connector 02 corresponding to the interface at the second end of the cable under test, wherein the first connector 01 and the second connector 02 are of different models; the power module 06 is used to provide power for the continuity detection of the cable under test; the display module 06 is used to display the continuity detection result of the cable under test; the start switch 04 is used to control the connection and disconnection of the power module 06, so as to control the start and stop of the continuity detection of the cable under test.

[0028] In some embodiments, reference Figure 1 The aforementioned cable continuity detection device is a cuboid structure consisting of six panels (front, back, left, right, top, and bottom), each made of insulating resin. The panels are secured to each other with hexagonal screws and three-sided multi-hole brackets. After securing, plugs are used to seal the screw holes, making the surface of the fixture smoother and more aesthetically pleasing. The upper panel of the cable continuity detection device includes a display module 03, a power module 06, a start switch 04, and a selector switch 05.

[0029] In some embodiments, reference Figure 4 The start switch includes a switch dial 041, a switch mounting hole 042, and a switch pin 043. The start switch is fixed to the top plate of the cable continuity detection device by screws.

[0030] In some embodiments, the power module is a battery box, see reference. Figure 5 The battery compartment has four mounting holes 065 and is secured to the top plate of the cable continuity detection device with four screws. The battery compartment also includes a negative terminal connector 061, a positive terminal connector 062, a power indicator 064, and mounting holes 066. This battery compartment can hold up to four 1.5V dry cell batteries, separated by dividers 063, providing a maximum DC voltage of 6V. In one example, the cable continuity detection device operates normally between 3V and 6V. The battery cover has five mounting holes 069 and is secured to the battery compartment with five screws. After installation, the cover plugs will cover the mounting holes for a more aesthetically pleasing appearance. Additionally, the battery cover has a live indicator 068 and four mounting hole plugs 067 to cover the mounting holes.

[0031] In some embodiments, reference Figure 2 The power module can also be a DC interface 06, and a fixed power supply is connected through this DC interface to power the cable continuity detection device.

[0032] In some embodiments, reference Figure 3 The first connector 01 and the second connector 02 are fixed to the front panel of the cable continuity detection device by Phillips head screws. In one example, the first connector is a J599 / 26WD35SC aviation plug, and the second connector is a DB37 female connector.

[0033] In some embodiments, reference Figure 1 The aforementioned cable continuity detection device also includes a tooling handle 07. In one example, the tooling handle is fixed to the right panel of the cable continuity detection device by an Allen screw.

[0034] It should be noted that when using the cable continuity testing device of this application embodiment, simply insert the interface (DB37 male) of the first end of the cable to be tested into the first connector (DB37 female) of a group of cable connectors, and then insert the interface (aviation plug female) of the second end of the cable to be tested into the second connector (aviation plug male) of the same group of cable connectors. After confirming that the connection is correct, the start switch can be toggled to perform the test, and the test results can be displayed through the display module. To facilitate differentiation, the first and second connectors of the same group of cable connectors are positioned adjacent to each other.

[0035] In some embodiments, reference Figure 1The cable continuity detection device further includes a switch 05 located on the housing. The switch 05 is used to switch the continuity detection of different cables when two or more cables to be tested are connected to the cable continuity detection device at the same time. In one example, the switch 05 can be fixed to the top plate of the cable continuity detection device with screws.

[0036] In some embodiments, reference Figure 2 and Figure 10 The aforementioned display module is an indicator light assembly 03, which illuminates when the continuity test result of the cable under test is a pass. It should be noted that, in one example, the indicator light assembly can be a single indicator light, with all connector sockets between the first and second connectors in the same group connected in series. Thus, the single indicator light will only illuminate when all the wires between the sockets at both ends of the cable under test are conductive, indicating that the continuity test result of the cable under test is a pass.

[0037] In some embodiments, reference Figure 2 , Figure 8 and Figure 9 The aforementioned indicator light assembly 03 includes multiple indicator lights; each cable connector includes multiple pairs of connector sockets, each pair of connector sockets including a first socket 0100 belonging to the first connector 01 and a second socket 0200 belonging to the second connector 02; each pair of connector sockets is provided with an indicator light to indicate the continuity test result of each pair of connector sockets. It should be noted that, in this embodiment, to more accurately determine which pair of sockets in the cable under test has a faulty wire, an indicator light can be set separately for each pair of connector sockets, and the pairs of connector sockets can be connected in parallel. This way, the correspondence between the indicator lights and the connector sockets can be used to accurately determine which two pairs of sockets in the cable under test have a problem with the wire.

[0038] In some embodiments, after confirming that the cable under test is correctly connected to a set of cable connectors, a switch can be used to select the corresponding channel, and then the start switch can be activated to perform the test. When all test points of the cable under test pass the test, multiple indicator lights in the indicator module will be lit. If any test point fails, the corresponding indicator light will be off. In this case, troubleshooting can be performed according to the pre-set reference wiring table. After the test is completed, the start switch must be switched to the off position before the test cable can be disconnected. In some embodiments, the pre-set reference wiring table specifies the positions of a pair of connector sockets corresponding to each indicator light.

[0039] In some embodiments, reference Figure 2 and Figure 6Each set of cable connectors corresponds to an indicator light assembly 03. For each set of cable connectors, the first end of the first connector 01 is used to connect to the interface of the second end of the cable under test, and the second end of the first connector 01 is connected to the first end of the indicator light assembly 03 corresponding to the cable connector. The second end of the indicator light assembly 03 corresponding to the cable connector is connected to the first end of the switch S2, and the second end of the switch S2 is connected to the input terminal of the power module. The first end of the second connector 02 is used to connect to the interface of the first end of the cable under test, and the second end of the second connector 02 is connected to the first end of the start switch S1. The second end of the start switch S1 is connected to the output terminal of the power module. In one example, refer to... Figure 6 The aforementioned cable continuity detection device is also equipped with a protective resistor R, which is connected in series with the start switch S1 and located between the start switch S1 and the output terminal of the power module. The protective resistor is used to limit the current in the circuit to prevent excessive current from damaging the indicator light.

[0040] It should be noted that the reference Figure 6 The cable continuity detection device includes two sets of cable connectors. When both sets of cable connectors are connected to the cable to be tested, the device can switch to the channel to be tested using the switch S2.

[0041] In some embodiments, reference Figure 7 Each group of cable connectors shares one indicator light assembly 03. For each group of cable connectors, the first end of the first connector 01 is used to connect to the interface of the other end of the cable to be tested, the second end of the first connector 01 is connected to the first end of the switch S2, the second end of the switch S2 is connected to the first end of the indicator light assembly 03, and the second end of the indicator light assembly 03 is connected to the input terminal of the power module. The first end of the second connector 02 is used to connect to the interface of the first end of the cable to be tested, the second end of the second connector 02 is connected to the first end of the start switch S1, and the second end of the start switch S1 is connected to the output terminal of the power module. It should be noted that... Figure 7 Corresponding embodiments and Figure 6 This allows two sets of cable connectors to share a single indicator light assembly, thereby reducing the number of indicator light assemblies required.

[0042] It should be noted that the first terminal of the switch in this application is a channel switching terminal, which includes multiple switchable sub-channels. When the channel switching terminal of the switch is connected to a certain sub-channel, it indicates that the current switch is switched to the corresponding channel of that sub-channel. In one example, the switch is a single-pole multi-throw switch.

[0043] In some embodiments, reference Figure 8The aforementioned first connector includes multiple first sockets 0100 that can form multiple first sub-connectors. Each first sub-connector can adapt to the interface of the first end of the aforementioned cable under test, and the multiple first sub-connectors have the same first socket. It should be noted that, in order to enable the first connector in this embodiment to adapt to the interfaces of multiple types of cables under test, multiple first sockets can be provided on the first connector, and these first sockets can be used to form multiple first sub-connectors. (Reference) Figure 8 The first connector includes three first sub-connectors, namely 011, 012, and 013, from smallest to largest. Each first sub-connector can be adapted to the interface of a cable to be tested. Moreover, the first socket 0100 corresponding to the first sub-connector 011 can be used by the first connectors 012 and 013 at the same time. By setting a common first socket, multiple first sub-connectors can be set in the limited area of ​​the first connector.

[0044] In some embodiments, a first display mark is provided on the target first socket located at the edge position among the plurality of target first sockets corresponding to each type of first sub-connector. It should be noted that, to help users distinguish each type of first sub-connector, a first display mark can be provided on the target first socket located at the edge position. This first display mark can be set as needed; for example, a preset color, such as red or yellow, can be applied to the target first socket. In one example, an indicator line can also be provided next to the target first socket, and then the indicator lines of the same first sub-connector are connected together to form a geometric shape that surrounds the first sub-connector, for example... Figure 8 The dashed box in the image is a display marker, and each dashed box corresponds to a first sub-connector.

[0045] In some embodiments, reference Figure 9 The aforementioned second connector includes multiple second sockets 0200 that can form various second sub-connectors. Each second sub-connector can adapt to the interface of the second end of the aforementioned cable under test, and the various second sub-connectors have the same second socket. It should be noted that, similar to the aforementioned first connector, in order to enable the second connector in this embodiment to adapt to the interfaces of various types of cables under test, multiple second sockets can be provided on the second connector, and these second sockets can be used to form various second sub-connectors. (Reference) Figure 9 The second connector includes three sub-connectors, 021, 022, and 023, from smallest to largest. Each sub-connector can be adapted to the interface of a cable to be tested. Moreover, the first socket 0200 corresponding to the second sub-connector 021 can be used by the second connectors 022 and 023 simultaneously. By setting a common first socket, multiple sub-connectors can be set within the limited area of ​​the second connector.

[0046] In some embodiments, a second display mark is provided on the target second socket located at the edge position among the plurality of target second sockets corresponding to each type of second sub-connector. It should be noted that the specific second display mark can be set with reference to the first display mark described above, and will not be elaborated further.

[0047] The cable continuity testing device of this application embodiment has at least one set of cable connectors on its housing. Each set of cable connectors includes a first connector and a second connector of different models. The first connector corresponds to the interface at the first end of the cable to be tested, and the second connector corresponds to the interface at the second end of the cable to be tested. This allows simultaneous connection of the interfaces at both ends of the cable to be tested using a single set of cable connectors, improving the efficiency of cable continuity testing and avoiding potential errors that might occur when manually checking each jack at both ends of the cable with a multimeter. This improves the accuracy of cable continuity testing. Furthermore, after the cable to be tested is connected to the set of cable connectors, turning on the start switch allows the display module on the continuity testing device housing to display the continuity test results, enabling users to intuitively observe the continuity status of the cable and reducing the operational difficulty of cable continuity testing. In addition, with the cable continuity testing device of this application embodiment, cable continuity testing only requires connecting the cable to the device; it eliminates the need for multimeter testing and personnel to locate test points, allowing for rapid testing and fault location. Moreover, since the product uses the matching cable connectors, it will not damage the interfaces at both ends of the cable.
