[0002] In order to ensure the stable function of the cable during use, it is necessary to detect the cable before use. The detection of the cable includes detecting the continuity of the wire cores inside the cable and the short circuit of the cable.

[0003] Currently, to detect the continuity of the wire cores of a cable, usually a thin copper wire is connected to each of the two test leads of a multimeter first, then the multimeter is switched to the continuity detection range. Two testers hold one end of the prefabricated cable respectively, and insert the copper wires on the two test leads into the same wire cores at both ends of the cable respectively, and check each wire core of the cable one by one starting from the first wire core. If the wire core is conductive, the buzzer of the multimeter will sound. To detect the short circuit of the wire cores of a cable, usually a thin copper wire is connected to each of the two test leads of a multimeter first, then the multimeter is switched to the continuity detection range. One test lead is placed on the outer shell of the prefabricated cable joint, and the copper wire on the other test lead is inserted into multiple wire cores of the prefabricated cable joint one by one. If the wire core is short-circuited with the joint shell, the buzzer will sound. Utility Model Content

[0004] In view of this, the cable detection device provided by the present utility model can quickly detect the continuity and short circuit of the wire cores of the cable, improving the efficiency.

[0005] An embodiment of the present utility model provides a cable detection device, including: a substrate, a power supply module, a first indicator light, a first cable interface, a second cable interface, and a plurality of test switches disposed on the substrate; the first cable interface has a plurality of first pins, the second cable interface has a plurality of second pins, and the number of the first pins and the number of the second pins both match the number of a plurality of cores of the cable; on the substrate, a first end of the power supply module is respectively connected to the plurality of first pins of the first cable interface through the plurality of test switches, a second end of the power supply module is respectively connected to the plurality of second pins of the second cable interface through the first indicator light, the plurality of first pins and the plurality of second pins are respectively connected to the plurality of cores of the cable one by one, and the second end of the power supply module is further connected to a short - circuit detection point on the second cable interface; the cable has a first connector and a second connector, the first cable interface is connected to the first connector, the second cable interface is connected to the second connector, and moreover, the short - circuit detection point on the second cable interface is connected to the outer shell of the second connector; when one of the plurality of test switches is turned on, the first indicator light determines whether there is a short - circuit or open - circuit problem in the core of the cable corresponding to the turned - on test switch by whether the first indicator light emits light.

[0006] In a possible implementation manner, when one of the plurality of test switches is turned on, the first indicator light is short - circuited because the core corresponding to the turned - on test switch is short - circuited to the outer shell of the second connector, so that the second connector is connected to the second end of the power supply module through the short - circuit detection point of the second cable interface and is short - circuited, and thus does not emit light.

[0007] In a possible implementation manner, when one of the plurality of test switches is turned on, the first indicator light does not form a loop with the power supply module because the core corresponding to the turned - on test switch is open - circuited, and thus does not emit light.

[0008] In a possible implementation manner, a current - limiting resistor is provided on the path where the plurality of test switches are connected to the second cable interface through the power supply module.

[0009] In a possible implementation manner, the current - limiting resistor is disposed between the plurality of test switches and the first end of the power supply module.

[0010] In a possible implementation manner, the cable detection device further includes a second indicator light, and the second indicator light is disposed between the plurality of test switches and the first end of the power supply module.

[0011] In a possible implementation, a pre-inspection switch is further provided on the substrate, and the power supply module, the first indicator light, and the pre-inspection switch are connected in series; when the pre-inspection switch is turned on, the first indicator light is connected in series with the power supply module, so as to determine whether the first indicator light is normal by whether the first indicator light emits light.

[0012] In a possible implementation, the short-circuit detection point is provided on the metal shell of the second cable interface. When the second cable interface is connected to the second connector of the cable, the short-circuit detection point is connected to the shell of the second connector through the metal shell; when there is a short-circuit problem with the wire core, when one of the multiple test switches is turned on, the first indicator light is short-circuited to the shell of the second connector because the wire core corresponding to the turned-on test switch is short-circuited, so that the second connector is short-circuited by being connected to the second end of the power supply module through the short-circuit detection point of the second cable interface, and thus does not emit light, while the second indicator light emits light; when there is an open-circuit problem with the wire core, when one of the multiple test switches is turned on, both the first indicator light and the second indicator light do not form a loop with the power supply module because the wire core corresponding to the turned-on test switch is open-circuited, and thus neither of them emits light.

[0013] In a possible implementation, the voltage of the power supply module is between 3V and 9V, the resistance value of the current-limiting resistor is between 150Ω and 400Ω, and the substrate is a PCB board.

[0014] In a possible implementation, the cable is a 62-core prefabricated cable, the cable has sixty-two wire cores, the first cable interface has sixty-two first pins, the second cable interface has sixty-two second pins, and the sixty-two first pins and the sixty-two second pins are respectively connected to the sixty-two wire cores of the cable one by one.

[0015] As can be seen from the above technical solution, the cable detection device connects the two ends of the cable to the first cable interface and the second cable interface respectively, and both the first cable interface and the second cable interface have a plurality of pins corresponding to the number of cores of the cable. Therefore, after the connectors at both ends of the cable are connected to the cable detection device, a plurality of pins can be docked one by one with the cores of the cable. Thus, a single person can quickly connect both ends of the cable to the cable detection device, which is convenient and fast. The first end of the power supply module is connected to the plurality of pins of the first cable interface through the plurality of test switches, and the second end of the power supply module is also connected to the short-circuit detection point on the second cable interface. Therefore, when detecting the continuity and short circuit of the cores of the cable, the short circuit and short circuit of the cores of the cable can be detected by turning on the plurality of test switches one by one. There is no need to use a multimeter, and a single person can also complete the detection of the cable cores, which is convenient, fast and simple to operate. The provided first indicator light can accurately indicate the continuity and short-circuit state of the cores. Brief Description of the Drawings

[0021] Detailed Description of the Embodiments

[0022] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0023] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0024] As mentioned above, in order to ensure the stable function of the cable during use, it is necessary to detect the cable before use. The detection of the cable includes detecting the continuity of the wire cores inside the cable and the short circuit of the cable.

[0025] Currently, to detect the continuity of the wire cores of a cable, usually a thin copper wire is connected to each of the two test leads of a multimeter first, and then the multimeter is switched to the continuity detection mode. Two testers each hold one end of the prefabricated cable, and insert the copper wires on the two test leads into the same wire cores at both ends of the cable respectively. Starting from the first wire core, each wire core of the cable is checked one by one. If the wire core is conductive, the buzzer of the multimeter sounds. For the short circuit detection of the wire cores of the cable, usually a thin copper wire is connected to each of the two test leads of a multimeter first, and then the multimeter is switched to the continuity detection mode. One test lead is placed on the outer shell of the prefabricated cable joint, and the copper wire on the other test lead is successively inserted into multiple wire cores of the prefabricated cable joint. If the wire core is short circuited with the joint shell, the buzzer sounds.

[0026] In an embodiment of the present utility model, the cable detection device 100 connects the two ends of the cable 200 to the first cable interface 40 and the second cable interface 50 respectively. The first cable interface 40 has a plurality of first pins 401, and the second cable interface 50 has a plurality of second pins 503. The number of the first pins 401 and the number of the second pins 503 both match the number of the wire cores of the cable 200. The cable 200 has a first joint 210 and a second joint 220. Therefore, after the cable 200 is connected to the cable detection device 100, the plurality of first pins 401 and the plurality of second pins 503 are respectively connected to the plurality of wire cores of the cable 200 one by one. Specifically, the first pins 401 can be correspondingly connected to the wire cores at the first joint 210 one by one, and the second pins 503 can be correspondingly connected to the wire cores at the second joint 220 one by one.

[0027] Thus, a single person can quickly connect the cable 200 to the cable detection device 100, which is convenient and fast. The first end of the power supply module 20 is connected to the plurality of first pins 401 of the first cable interface 40 through a plurality of test switches 60 respectively, and the second end of the power supply module 20 is also connected to the short circuit detection point 502 on the second cable interface 50. Therefore, when detecting the continuity and short circuit of the wire cores of the cable 200, by successively switching on the plurality of test switches 60, the detection of the short circuit and continuity of the wire cores of the cable 200 can be realized. There is no need to use a multimeter, and a single person can also complete the detection of the wire cores of the cable 200, which is convenient, fast and simple to operate. The provided first indicator light 30 can accurately indicate the continuity and short circuit states of the wire cores.

[0028] The following combines the Figures 1-4 description of the specification, and details a cable detection device 100 according to an embodiment of the present utility model.

[0029] A cable detection device 100 according to an embodiment of the present utility model. As Figures 1-4 shown, the cable detection device 100 includes a substrate 10, a power module 20 disposed on the substrate 10, a first indicator light 30, a first cable interface 40, a second cable interface 50, and a plurality of test switches 60. Specifically, the substrate 10 can provide a stable installation foundation for the installation of other structures, ensuring stable connection and cooperation between other structures. The power module 20 can provide electrical energy for the entire cable detection device 100. It should be noted that the power module 20 can be a power source such as a battery, or a rechargeable battery or other power source that can be reused multiple times.

[0030] As Figures 1-4 shown, the first cable interface 40 has a plurality of first pins 401, and the second cable interface 50 has a plurality of second pins 503. The number of the first pins 401 and the number of the second pins 503 both match the number of a plurality of wire cores of the cable 200. The cable 200 has a first connector 210 and a second connector 220. The first cable interface 40 is connected to the first connector 210 of the cable 200. The second cable interface 50 is connected to the second connector 220 of the cable 200. Therefore, after the two connectors of the cable 200 are respectively connected to the first cable interface 40 and the second cable interface 50, the first pins 401 can be connected to the wire cores at the first connector 210 one by one, and the second pins 503 can be connected to the wire cores at the second connector 220 one by one. It is convenient to realize the detection operation of the wire cores of the cable 200 by a single person, that is, a single person can quickly connect the first connector 210 and the second connector 220 of the cable 200 to the cable detection device 100, which is convenient and fast.

[0031] On the substrate 10, a first end of the power module 20 is respectively connected to a plurality of first pins 401 of the first cable interface 40 through a plurality of test switches 60, a second end of the power module 20 is respectively connected to a plurality of second pins 503 of the second cable interface 50 through the first indicator light 30. The plurality of first pins 401 and the plurality of second pins 503 are respectively connected to a plurality of wire cores of the cable 200 one by one. The second end of the power module 20 is also connected to a short-circuit detection point 502 on the second cable interface 50, and the short-circuit detection point 502 on the second cable interface 50 is connected to the outer shell of the second connector 220. Among them, when one of the plurality of test switches 60 is turned on, the first indicator light 30 determines whether there is a short circuit or an open circuit problem with the wire core corresponding to the turned-on test switch 60 in the cable 200 by whether the first indicator light 30 emits light.

[0032] It should be noted here that as Figures 1-4As shown, for ease of description, the first cable interface 40 can be a cable interface provided on the left side of the substrate 10, and the second cable interface 50 can be a cable interface provided on the right side of the substrate 10. Correspondingly, the first end of the power module 20 can be its left end, and the second end of the power module 20 can be its right end.

[0033] Specifically, multiple first pins 401 of the first cable interface 40 can be correspondingly connected to multiple wire cores of the first connector 210 of the cable 200 one by one. At the same time, the first end of the power module 20 can be connected to multiple first pins 401 of the first cable interface 40 one by one through multiple test switches 60. Correspondingly, multiple second pins 503 of the second cable interface 50 can be correspondingly connected to multiple wire cores of the second connector 220 of the cable 200 one by one. Thus, it can be understood that when the first connector 210 of the cable 200 is connected to the first cable interface 40 of the cable detection device 100 and the second connector 220 is connected to the second cable interface 50, multiple wire cores of the cable 200 form a loop whose on-off is controlled by multiple test switches 60 with the internal circuit of the cable detection device 100.

[0034] Therefore, by sequentially switching multiple test switches 60, the wire cores of the cable 200 can be sequentially connected or disconnected from the loop formed by the internal circuit of the cable detection device 100. As Figure 2 shown, when one of the multiple test switches 60 is closed and the remaining test switches 60 remain open, the power module 20 supplies electrical energy. If the wire core of the cable 200 corresponding to this test switch 60 is open-circuited, it can be understood that a closed loop cannot be formed between the cable detection device 100 and the wire core of the cable 200, and the first indicator light 30 will not emit light. That is, as Figure 2 shown, where the wire core is shown as L1 in the figure, when the wire core L1 is open-circuited, its break point is shown as point A in the figure. Even after the test switch 60 corresponding to the wire core L1 is closed, since the wire core L1 is open-circuited, the first indicator light 30 will not emit light. If the wire core is not open-circuited, correspondingly, a closed loop is formed between the cable detection device 100 and the wire core of the cable 200, so the first indicator light 30 emits light. Thus, the on-off conditions of multiple wire cores can be quickly tested sequentially, realizing the rapid detection of multiple wire cores of the cable 200.

[0035] Furthermore, as Figure 3As shown, a branch circuit is formed in parallel with the first indicator light 30 between the short - circuit detection point 502 of the second cable interface 50 and the second end of the power supply module 20. When the outer covering of the core of the cable 200 is damaged, the core of the cable 200 is connected at the damaged part of its outer covering and the outer shell of the connector of the cable 200, and further forms a path through the short - circuit detection point 502 and the second end of the power supply module 20. Thus, after the test switch 60 is closed, the first indicator light 30 will be short - circuited, that is, the first indicator light 30 will not emit light. On the contrary, the first indicator light 30 will emit light normally. Therefore, the cable detection device 100 can quickly detect the short - circuit conditions of multiple cores of the cable 200 in sequence.

[0036] For example, as Figure 3 shown, where the core is shown as L3 in the figure, the outer covering of the core of the cable 200 is damaged, generally at the connector of the cable 200. Here, the second connector 220 of the cable 200 is taken as an example. The outer shells of the first connector 210 and the second connector 220 of the cable 200 are both metal shells. When installing an external metal shell at the first connector 210 or the second connector 220 of the cable 200, usually the metal shell is opened and sleeved outside the core, and then the metal cover plate of the metal shell is installed, so as to encapsulate the core in the metal shell. When the core L2 is placed inside the metal shell of the second connector 220, when installing the metal cover plate, since the metal material of the metal cover plate may press the outer covering outside the core L2, the outer covering of the core L2 is damaged by extrusion, and the damaged part is as Figure 3 shown at point B, so the core L2 will be conducted with the metal shell at B after being electrified.

[0037] Furthermore, since the outside of the second cable interface 50 has a metal shell 501, the second connector 220 will be conducted with the metal shell 501 at the second cable interface 50, and then a branch parallel to the first indicator light 30 is formed through connection at the short - circuit detection point 502 and the power supply module 20, resulting in a short - circuit of the first indicator light 30, that is, the first indicator light 30 cannot emit light.

[0038] According to the cable detection device 100 of the embodiment of the present utility model, by connecting both ends of the cable 200 to the first cable interface 40 and the second cable interface 50 respectively, and the first cable interface 40 has a plurality of first pins 401, and the second cable interface 50 has a plurality of second pins 503. The number of the first pins 401 and the number of the second pins 503 both match the number of the plurality of cores of the cable 200. Therefore, after the cable 200 is connected to the cable detection device 100, the first pins 401 can be connected to the cores at the first joint 210 one by one, and the second pins 503 can be connected to the cores at the second joint 220 one by one. Thus, a single person can achieve the quick connection of both ends of the cable 200 to the cable detection device 100, which is convenient and fast. The first end of the power supply module 20 is connected to a plurality of first pins 401 of the first cable interface 40 through a plurality of test switches 60 respectively, and the second end of the power supply module 20 is also connected to the short - circuit detection point 502 on the second cable interface 50. Therefore, when detecting the continuity and short - circuit of the cores of the cable 200, by switching on a plurality of test switches 60 one by one, the detection of the short - circuit and continuity of the cores of the cable 200 can be achieved. There is no need to use a multimeter, and a single person can also complete the detection of the cores of the cable 200, which is convenient, fast, and simple to operate. The provided first indicator light 30 can accurately indicate the continuity and short - circuit states of the cores.

[0039] It should be noted that for the short - circuit or open - circuit of the cores of the cable 200 in the previous text, for the convenience of understanding, the following explanations are given:

[0040] As Figure 3 shown, when one of the plurality of test switches 60 is turned on, the first indicator light 30 is short - circuited because the core corresponding to the turned - on test switch 60 is short - circuited to the outer shell of the second joint 220, so that the second joint 220 is short - circuited through the short - circuit detection point 502 of the second cable interface 50 and connected to the second end of the power supply module 20, and thus does not emit light.

[0041] In other words, a short - circuit means that after one of the plurality of test switches 60 is turned on, the core corresponding to the turned - on test switch 60 is connected to the outer shell of the second joint 220, and the second joint 220 is connected to the second end of the power supply module 20 through the short - circuit detection point 502 of the second cable interface 50. Therefore, the first indicator light 30 does not emit light.

[0042] As Figure 2 shown, when one of the plurality of test switches 60 is turned on, the first indicator light 30 does not emit light because the core corresponding to the turned - on test switch 60 is open - circuited and does not form a loop with the power supply module 20.

[0043] In other words, when one of the plurality of test switches 60 in the open circuit is turned on, the core wire corresponding to the turned-on test switch 60 is open-circuited. Therefore, after the cable 200 is connected to the cable detection device 100, a closed loop cannot be formed, and thus the first indicator light 30 does not emit light.

[0044] In some embodiments of the present invention, as Figure 1 shown, a current-limiting resistor 80 is provided on the path where the plurality of test switches 60 are connected to the second cable interface 50 through the power supply module 20. The current-limiting resistor 80 can limit the current passing through the power supply module 20 when a short circuit occurs in the core wire of the cable 200, preventing the current passing through the power supply module 20 from being too large due to the short circuit, which may cause damage to the power supply module 20. Moreover, the paths for detecting short circuits or open circuits of the core wires of the cable 200 both include the part where the plurality of test switches 60 are connected to the left end of the first indicator light 30 through the power supply module 20. If a current-limiting resistor 80 is provided in this connection part, the current-limiting resistor 80 can also effectively share the voltage of the first indicator light 30 when the open-circuit detection of the core wire of the cable 200 is normal, limit the current passing through the first indicator light 30, and prevent the current passing through the first indicator light 30 from being too large, which may cause damage to the first indicator light 30.

[0045] In some embodiments of the present invention, as Figure 1 shown, the current-limiting resistor 80 is provided between the plurality of test switches 60 and the first end of the power supply module 20. Specifically, setting the current-limiting resistor 80 at this position can provide short-circuit protection for the power supply module 20 during short-circuit detection of the core wire, and can also share the voltage of the first indicator light 30 when there are no open-circuit and short-circuit problems with the core wire, ensuring the stable operation of the first indicator light 30.

[0046] In some embodiments of the present invention, as Figure 4 shown, the cable detection device 100 further includes a second indicator light 70, and the second indicator light 70 is provided between the plurality of test switches 60 and the first end of the power supply module 20. Therefore, when an open circuit occurs in the core wire of the cable 200, both the first indicator light 30 and the second indicator light 70 do not emit light. When the outer covering of the core wire is damaged and a short circuit occurs, the first indicator light 30 does not emit light, while the second indicator light 70 emits light, so that it can be determined that the core wire has a short circuit.

[0047] Among them, the second indicator light 70 in the present invention can use a second indicator light 70 with a resistance of 150 to 300 ohms.

[0048] As Figures 1-4As shown, a pre-inspection switch 90 is also provided on the substrate 10. The power supply module 20, the first indicator light 30, and the pre-inspection switch 90 are connected in series. When the pre-inspection switch 90 is turned on, the first indicator light 30 is connected in series with the power supply module 20, so as to determine whether the first indicator light 30 is normal according to whether the first indicator light 30 emits light.

[0049] Specifically, as Figure 1 shown, when the cable detection device 100 is not connected to the cable 200, or all the test switches 60 are turned off, closing the pre-inspection switch 90 can enable the power supply module 20, the first indicator light 30, and the pre-inspection switch 90 to form a loop whose on-off is controlled by the pre-inspection switch 90, so as to detect whether there is an open circuit between the first indicator light 30 and the power supply module 20 or whether the first indicator light 30 is damaged. If the first indicator light 30 emits light at this time, it means that the first indicator light 30 and the power supply module 20 are normally connected. Correspondingly, if the first indicator light 30 does not emit light, further check whether the first indicator light 30 is damaged or the circuit is disconnected. Thus, the state of the cable detection device 100 can be quickly detected.

[0050] As Figure 1 shown, the short-circuit detection point 502 is provided on the metal shell 501 of the second cable interface 50. When the second cable interface 50 is connected to the second joint 220 of the cable 200, the short-circuit detection point 502 is connected to the shell of the second joint 220 through the metal shell 501. Therefore, when there is a short-circuit problem with the wire core, when one of the multiple test switches 60 is turned on, the first indicator light 30 is short-circuited to the shell of the second joint 220 because the wire core corresponding to the turned-on test switch 60 is short-circuited, so that the second joint 220 is short-circuited through the short-circuit detection point 502 of the second cable interface 50 and connected to the second end of the power supply module 20, and thus does not emit light, while the second indicator light 70 emits light.

[0051] In other words, the metal shell 501 of the second cable interface 50 can fit after being connected to the joint 210 of the cable 200. If there is a problem of wire core breakage and leakage, it will be connected to the second end of the power supply module 20 through the metal shell 501 and the short-circuit detection point 502. Therefore, the first indicator light 30 does not emit light, while the second indicator light 70 emits light. Thus, it is possible to detect whether the wire core is short-circuited through the cable detection device 100. Optionally, the short-circuit detection point 502 can also be provided at any other position electrically connected to the metal shell 501 of the second cable interface 50.

[0052] When there is an open circuit problem in the wire core, when one of the multiple test switches 60 is turned on, both the first indicator light 30 and the second indicator light 70 are not in a loop with the power supply module 20 because the wire core corresponding to the turned-on test switch 60 is open, so neither of them emits light. That is, after the cable 200 is connected to the cable detection device 100, a closed loop cannot be formed, so neither the first indicator light 30 nor the second indicator light 70 emits light.

[0053] In some embodiments of the present invention, the voltage of the power supply module 20 is between 3V and 9V, and the resistance value of the current limiting resistor 80 is between 150Ω and 400Ω. Among them, the voltage of the power supply module 20 can be selected as a voltage matching the rated voltage of the first indicator light 30. Of course, the voltage of the power supply module 20 can also be selected as a voltage between 3V (volt) and 9V (volt), and at the same time, the resistance value of the current limiting resistor 80 is selected between 150Ω (ohm) and 400Ω (ohm), so that the voltage that the first indicator light 30 can be allocated is above 2V (volt).

[0054] In some embodiments of the present invention, the first indicator light 30 can be an LED light. The working voltage of the LED light is generally between 2V (volt) and 3.6V (volt), and the working current is between 0.02A (ampere) and 0.03A (ampere). Therefore, its energy consumption is low. At the same time, it generates less heat and has a long service life.

[0055] In some embodiments of the present invention, the substrate 10 is a PCB board. Using a PCB board as the substrate 10, since there are circuit lines on the PCB board itself, the first cable interface 40 and the second cable interface 50 are arranged on the PCB board by welding, and the power supply module 20 and the first indicator light 30 are arranged on the PCB board, which can quickly form a loop between each structure, which is convenient and fast.

[0056] In some embodiments of the present invention, the cable 200 is a 62-core prefabricated cable 200, and the cable 200 has sixty-two wire cores. Specifically, the cable 200 is suitable for supporting the Siemens EU905 / EU903 rack. Therefore, the rack with the cable 200 can quickly detect the continuity and short circuit of the wire cores of the cable 200 during use, which is convenient and fast, and can be operated by a single person.

[0057] Further, there are sixty-two first pins 401 in the first cable interface 40, and sixty-two second pins 503 in the second cable interface 50. The sixty-two first pins 401 and the sixty-two second pins 503 are respectively connected to the sixty-two wire cores of the cable 200 one by one. Thus, after the first connector 210 of the cable 200 is connected to the first cable interface 40 and the second connector 220 is connected to the second cable interface 50, the sixty-two first pins 401 and the sixty-two second pins 503 can be quickly docked with the sixty-two wire cores of the cable 200 respectively, which is convenient for subsequent detection.
