The existing wire diameter of the wired ignition wire is small, and in actual use, many of them are usually arranged together densely, which leads to problems with the ignition wire. For example, when it is disconnected or short-circuited, it cannot be directly observed by the eyes, and detection equipment is needed to detect the ignition wire. At present, a multimeter is usually used to detect the ignition wire, but the multimeter can only detect one ignition wire at a time, which is time-consuming, labor-intensive, and inefficient.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] like Figures 1 to 3 As shown, an embodiment of the present application provides a detection device 100 for a cable arrangement, wherein the cable arrangement includes a plurality of connection ends fixed to each other and a plurality of ignition wires, each connection end being connected to a corresponding ignition wire, and the detection device is used to connect to the plurality of connection ends of the cable arrangement to detect the ignition wires.

[0032] Please also see Figure 4 and Figure 5 Furthermore, the detection device 100 includes a housing 110 , a detection circuit board 120 , a detection connector 140 and a first display component 150 .

[0033] The housing 110 has an installation cavity. The detection circuit board 120 is disposed in the installation cavity. The detection circuit board 120 is provided with a detection module 130 and a display module.

[0034] The detection connector 140 and the first display assembly 150 are both disposed on the detection circuit board 120, and the detection connector 140 and the first display assembly 150 are partially exposed on the surface of the housing 110. The detection connector 140 is used to connect to multiple connection ends of the flat cable, and the detection module 130 is electrically connected to the detection connector 140 to detect the resistance of multiple ignition wires; the display module is electrically connected to the detection module 130 and the first display assembly 150, and the display module can obtain the detection data of the detection module 130, and transmit the detection data to the first display assembly 150, so as to be visually displayed through the first display assembly 150.

[0035] Furthermore, the detection device also includes a battery, which is arranged in the installation cavity. A power supply module is also provided on the detection circuit board 120. The battery is electrically connected to the power supply module for providing power. The power supply module is electrically connected to the detection module 130, the display module and the first display component 150.

[0036] By using the above-mentioned detection equipment, the connecting end of the flat cable is inserted into the detection connector 140, the flat cable is connected to the detection connector 140, and then the resistance of the ignition wire is detected through the detection module 130. The detection result is transmitted to the first display component 150 for display through the display module. In this way, it can be determined whether there is an abnormality in the ignition wire in the flat cable based on the displayed resistance data. Since the flat cable is connected through the detection connector 140, multiple ignition wires can be detected at the same time, which effectively improves the detection efficiency and saves time and effort. In addition, the detection power is provided by the battery arranged in the installation cavity, and no external power supply is required, which is more convenient to use.

[0037] It should be explained that there are at least two ways to judge whether there is an abnormality in the cable: First, the resistance of each ignition line has a reference resistance value, for example, the resistance of a 2m long ignition line is 1.8~2Ω, the resistance of a 5m long ignition line is 3~3.2Ω, and the resistance of an 8m long ignition line is 4.2~4.4Ω. The displayed resistance value can be compared with the reference value to judge whether there is an abnormality in the cable. If a certain resistance value is significantly smaller than the reference value, it indicates that the ignition line is short-circuited. If a certain resistance value cannot be displayed or the displayed resistance value is too large, it indicates that the ignition line may be open-circuited or other reasons may cause the resistance value to increase. Second, the lengths of multiple ignition lines on each cable are the same, so the resistances of multiple ignition lines should also be close. If the multiple resistance values ​​displayed during the cable detection are quite different, it can be judged that the cable is abnormal. Of course, a combination of the two methods can also be used for judgment, which is not limited here.

[0038] In one embodiment, the housing 110 includes an upper housing and a bottom housing, which are fastened by screws and enclose a mounting cavity. Specifically, the upper housing and the bottom housing are both made of metal, and the housing 110 is a rectangular parallelepiped.

[0039] In one embodiment, the detection device further includes a charging connector 161, which is disposed on the detection circuit board 120 and partially exposed on the surface of the housing 110. The charging connector 161 is electrically connected to the battery, and the charging connector 161 is used to electrically connect to an external power source, thereby charging the battery. In this embodiment, the charging connector 161 uses a 7.4V interface, and the device can be charged by inserting a 7.4V charger.

[0040] Furthermore, the detection device also includes a power indicator light 162, which is arranged on the detection circuit board 120 and partially exposed on the surface of the housing 110. The power indicator light 162 is electrically connected to the power supply module, and the power supply module can detect the remaining power of the battery and display the remaining power range through the power indicator light 162. For example, if the remaining power of the battery is less than 30%, the power indicator light 162 can flash to remind charging. At the same time, the power indicator light 162 can also be set to display different colors, for example, displaying green light indicates sufficient power; displaying yellow light indicates medium power; displaying red light indicates low power.

[0041] Furthermore, the detection device further includes a power switch 163, which is disposed on the detection circuit board 120 and partially extends out of the housing 110. The power switch 163 is connected between the battery and the power supply module, and is used to conduct or disconnect the connection between the battery and the power supply module to realize the opening and closing of the detection device. Of course, when the power switch 163 is turned on, the power indicator light 162 will also light up. If the power indicator light 162 is not lit, it indicates that the battery is exhausted or the power supply circuit is abnormal.

[0042] In one embodiment, the detection connector 140 includes a plurality of access terminals, each of which is used to connect to a corresponding connection terminal, thereby achieving connection with a corresponding ignition wire. Figure 3 In the illustrated embodiment, the detection connector 140 is a 16P DC header socket to facilitate insertion of a flat cable with 8 connection terminals.

[0043] In one embodiment, the first display assembly 150 includes a plurality of display screens, each of which is electrically connected to the display module and is used to obtain and visually display the detection data of a corresponding ignition wire, that is, to display the detected resistance value of the ignition wire.

[0044] Specific to Figure 1 In the embodiment shown, the resistance display range of the display screen is 0-9.9Ω, so when the detected resistance value is greater than 9.9Ω, the display screen will not display the resistance value. Of course, the normal resistance value of the ignition wire detected in this embodiment will not be greater than 9.9Ω.

[0045] In one embodiment, a comparison module is further provided on the detection circuit board 120, and the comparison module is electrically connected to the detection module 130 and the power supply module, and the comparison module can obtain the detection data of the detection module 130 and perform comparison processing on it, so as to determine whether the cable is normal. It can be understood that the comparison method is the same as the above-mentioned method of determining whether the cable is abnormal, that is, it can be compared with a reference value, or multiple resistance values ​​can be compared.

[0046] Furthermore, the detection device also includes a second display component, which is electrically connected to the comparison module, and the second display component can display the comparison result of the comparison module, so as to facilitate the operator to quickly obtain information to determine whether the cable is normal. Of course, in other embodiments, a wireless module can also be set to transmit the comparison result to the host computer for the operator to obtain.

[0047] Specific to Figure 1 In the illustrated embodiment, the second display component includes a normal light 171 and an abnormal light 172. Both the normal light 171 and the abnormal light 172 are disposed on the detection circuit board 120 and are partially exposed to the housing 110. Both the normal light 171 and the abnormal light 172 are electrically connected to the comparison module. When the comparison result shows that the wiring is normal, the normal light 171 is lit; when the comparison result shows that the wiring is abnormal, the abnormal light 172 is lit. Preferably, the normal light 171 displays green light, and the abnormal light 172 displays red light.

[0048] Specific to Figure 6 In the embodiment shown, the method for judging whether the resistance values ​​of multiple ignition wires are greatly different is as follows: taking eight ignition wires as an example, eight resistance values ​​are obtained, and the difference between the maximum resistance value and the minimum resistance value is written down and calculated. If the difference is greater than 0.6, it indicates that the wiring is abnormal, and the abnormal light 172 is turned on. If the difference is not greater than 0.6, the normal light 171 is turned on.

[0049] It should be explained that the probability of all ignition wires in the cable being abnormal is extremely low, so the normal light 171 and the abnormal light 172 are lit according to the difference in multiple resistance values. Of course, the operator can also observe the resistance value detected by any ignition wire. If the normal light 171 is lit, but the display screen shows that the resistance is abnormal, it means that all ignition wires in the cable are abnormal.

[0050] See also Figure 5 In one embodiment, the detection module 130 includes a plurality of detection circuits 131 , each detection circuit 131 is electrically connected to the power supply module and a corresponding access terminal, so that the resistance of the ignition line is detected through the detection circuit 131 .

[0051] Furthermore, a control module 180 is provided on the detection circuit board 120, and the detection module 130 also includes an AD converter 132. The above-mentioned comparison module and display module can be integrated into the control module 180. The control module 180 is electrically connected to the power supply module and the AD converter 132. The AD converter 132 is electrically connected to multiple detection circuits 131. The detection circuit 131 can transmit the detected voltage signal to the AD converter 132 to convert it into a digital signal. After obtaining the digital signal of the AD converter 132, the control module 180 compares and judges the data, and then transmits the result to the first display component 150 and the second display component.

[0052] Specifically, the detection circuit 131 is a constant current loop.

[0053] In order to facilitate understanding of the technical solution of the present application, the detection process of the detection device in the above embodiment is described here:

[0054] First turn on the power switch 163, the power indicator light 162 displays normal, then insert one end of the cable into the detection connector 140, observe the normal light 171 and the abnormal light 172, if the normal light 171 is on and the abnormal light 172 is off, it indicates that the cable is normal; if the normal light 171 is off and the abnormal light 172 is on, it indicates that the cable is abnormal, then you can continue to check the display results of each display screen to determine the specific abnormal ignition wire; if the normal light 171 and the abnormal light 172 are both off, and the display screen does not display, it indicates that the cable is not fully inserted.

[0055] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
