Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wire harness quality inspection equipment, and particularly to a fast detection device for a wire harness with aviation plugs at both ends. Background Art
[0002] With the increasingly fast and efficient development of power distribution technology, new requirements are put forward for high-voltage ring main units. Most high-voltage ring main units are placed outdoors and unattended. To achieve remote control, most high-voltage ring main units are equipped with remotely controllable DTU communication modules. The DTU communication module remotely controls each ring main cabinet in the high-voltage ring main unit. Therefore, the DTU communication module needs to collect data and exchange information with each ring main cabinet. Whether the data connection between the two is accurate or not will determine the quality of remote control.
[0003] The wire harness with aviation plugs at both ends acts like a bridge between the DTU communication module and the ring main cabinet. By configuring corresponding aviation plug pins and sockets on the DTU communication module and the ring main cabinet, and then connecting the DTU communication module and the ring main cabinet through the wire harness with aviation plugs at both ends, not only the workload during the production of the high-voltage ring main unit is reduced, but also the rapid docking of information between the DTU communication module and the ring main cabinet can be achieved by plugging and unplugging the aviation plugs, as well as the rapid replacement of the wire harness in the later stage.
[0004] The traditional detection method is to directly measure the continuity of each wire harness group with a multimeter or, during the project commissioning stage, to judge the quality of the wire harness by actually operating and simulating whether data can be normally communicated between the two. Although both of these two methods can detect the quality of the wire harness, the operation cycle is long, which reduces the quality inspection efficiency and thus reduces the production efficiency of qualified wire harnesses.
[0005] Therefore, the present application provides a fast detection device for a wire harness with aviation plugs at both ends, enabling the wire harness to quickly complete the inspection of wire harness continuity and correct phase sequence arrangement before installation and commissioning, shortening the production cycle and inspection cycle. Utility Model Content
[0006] The purpose of the present application is to solve the problems existing in the prior art, and to propose a fast detection device for a wire harness with aviation plugs at both ends.
[0007] To achieve the above purpose, the present application adopts the following technical solutions:
[0008] A fast detection device for a wire harness with aviation plugs at both ends, including a detection host, a wire harness, and a display;
[0009] A number of indicator lights one are evenly distributed on the front end face of the detection host, and output terminals electrically connected to the indicator lights one are provided on the side wall. The output terminals are commonly electrically connected to a socket one;
[0010] A number of indicator lights two are evenly distributed on the front end face of the display, and input terminals electrically connected to the indicator lights two are provided on the side wall. The input terminals are commonly electrically connected to a plug two;
[0011] One end of the wire harness is equipped with a plug one adapted to the socket one, and the other end is equipped with a socket two adapted to the plug two.
[0012] Preferably, a battery is installed in the detection host, a power switch is provided on the left side, output terminals are provided on the right side, and a control chip is provided inside.
[0013] Preferably, the display is a signal receiving device.
[0014] Preferably, the output terminals and the socket one, and the input terminals and the plug two are all connected by flexible wires.
[0015] Compared with the prior art, the present application provides a wire harness quick detection device with aviation plugs at both ends, having the following beneficial effects:
[0016] Turn on the detection host, the detection host is powered on, and then several indicator lights one are powered on one by one:
[0017] When the first indicator light one is powered on and lights up, the current passes through the first wire core and then is transmitted to the first indicator light two. If the first indicator light two lights up, the corresponding first wire core is okay. If the first indicator light two does not light up, then the corresponding first wire core is damaged; and if the indicator light two at other positions lights up, it means that the wire core is okay but the connection is wrong.
[0018] The detection of the remaining wire cores is carried out by analogy until the entire wire harness is detected. By using whether the indicator lights one and the indicator lights two light up or whether the lighting positions correspond, it can quickly detect whether the wire cores in the wire harness are damaged or whether the ends are connected wrongly, and even can detect the position of the contacted ends, greatly improving the detection efficiency and detection function, thereby improving the overall work efficiency and production efficiency.

[0028] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the appended Figure 1-7 , Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.
[0029] To solve the problems existing in the prior art, this embodiment provides a wiring harness quick detection device with aviation plugs at both ends, including a detection host 1, a wiring harness 16, and a display 11;
[0030] A number of indicator lights one 12 are evenly distributed on the front end face of the detection host 1, and output terminals 4 electrically connected to the indicator lights one 12 are provided on the side wall. The output terminals 4 are commonly electrically connected to a socket one 6;
[0031] A number of indicator lights two 13 are evenly distributed on the front end face of the display 11, and input terminals 10 electrically connected to the indicator lights two 13 are provided on the side wall. The input terminals 10 are commonly electrically connected to a plug two 9;
[0032] One end of the wiring harness 16 is provided with a plug one 7 adapted to the socket one 6, and the other end is provided with a socket two 8 adapted to the plug two 9.
[0033] Principle details of this embodiment:
[0034] A wiring harness quick detection device with aviation plugs at both ends, including a detection host 1, a wiring harness 16, and a display 11.
[0035] The detection host 1 is a high-potential emission device (high level: 3.5 - 5V). A number of first indicator lights 12 are evenly distributed on the front end face of the detection host 1, and output terminals 4 electrically connected to the first indicator lights 12 are provided on the side wall. The output terminals 4 are commonly electrically connected to a first socket 6; the detection host 1 can emit high potential to a number of first indicator lights 12 one by one at equal intervals, that is, power on a number of first indicator lights 12 one by one at equal intervals, so that a number of first indicator lights 12 light up one by one at equal intervals.
[0036] A number of second indicator lights 13 are evenly distributed on the front end face of the display 11, and input terminals 10 electrically connected to the second indicator lights 13 are provided on the side wall. The input terminals 10 are commonly electrically connected to a second plug 9.
[0037] The wire harness 16 is composed of a number of wire cores. One end of the wire harness 16 is provided with a first plug 7 adapted to the first socket 6, and the other end is provided with a second socket 8 adapted to the second plug 9.
[0038] In use, insert the first plug 7 into the first socket 6 and the second plug 9 into the second socket 8, so as to connect the detection host 1, the wire harness 16, and the display 11 into a whole, and the actual connection circuit is the first indicator lights 12, the wire cores, and the second indicator lights 13. Turn on the detection host 1, the detection host 1 is powered on, and then power on a number of first indicator lights 12 one by one:
[0039] The first first indicator light 12 is powered on and lights up. The current is transmitted to the first second indicator light 13 after passing through the first wire core. If the first second indicator light 13 lights up, the corresponding first wire core is intact. If the first second indicator light 13 does not light up, then the corresponding first wire core is damaged; if the second indicator light 13 at other positions lights up, it means that the wire core is intact but the connection is incorrect.
[0040] The detection of the remaining wire cores is carried out in the same way until the entire wire harness 16 is detected. By using whether the first indicator lights 12 and the second indicator lights 13 light up or whether the lighting positions correspond, it can quickly detect whether the wire cores in the wire harness 16 are damaged or whether the ends are connected wrongly, and even can detect the position of the contacted ends, greatly improving the detection efficiency and detection function, thereby improving the overall work efficiency and production efficiency.
[0041] In a further embodiment of this solution, a battery 2 is installed in the detection host 1, a power switch 3 is provided on the left side, an output terminal 4 is provided on the right side, and a control chip 14 is provided inside.
[0042] The battery 2 is used as a power source for power supply.
[0043] The model of the chip 14 is: CD4017. The output end of the control chip 14 can output a group of high potentials according to a pre-designed program, and the output speed can be adjusted high or low. To achieve the sequential interval turning on of the first indicator lights 12.
[0044] In a further embodiment of this solution, the display 11 is a signal receiving device. It can receive a medium flow, such as an electric current, from the wire harness 16 and transmit the medium flow to the corresponding second indicator light 13.
[0045] In a further embodiment of this solution, both the first indicator lights 12 and the second indicator lights 13 are 58 in number. The wire harness 16 has different models, and the number of wire cores contained inside it is also different. By setting 58 circuits, it is possible to include as many wire harness 16 quantities of different types of wire harnesses 16 as possible, and to expand the retrieval range of wire harnesses 16 with different numbers of wire cores as much as possible.
[0046] In a further embodiment of this solution, both between the output terminal 4 and the first socket 6 and between the input terminal 10 and the second plug 9 are connected by a flexible wire 5. This is to improve the movement flexibility and position extensibility of the first socket 6 and the second plug 9.
[0047] Preferably, in this solution, each first indicator light 12 corresponds to a battery 2, and each battery 2 is electrically connected to a switch. The switch is a push-button switch and is arranged on the side of the corresponding first indicator light 12. In this way, the on / off of the first indicator light 12 can be independently controlled. In this way, for wire harnesses 16 with different numbers of wire cores, only by connecting to the position of the first indicator light 12 corresponding to the conductive part connected to the wire core on the first plug 7, the corresponding first indicator light 12 can be turned on correspondingly, without the need to turn on and off all the first indicator lights 12 as a whole once.
[0048] This solution also provides Figure 2 , Figure 3 , which is the electrical schematic diagram of the quick detection device for the wire harness 16 with aviation plugs at both ends of this application. Combining Figure 2 , the operation of this application is discussed once again:
[0049] After the power switch 3 of the detection host 1 is turned on, the power indicator light connected to the battery 2 will be lit. Subsequently, after a short delay, the controller chip 14 of the detection host 1 first outputs a high potential and passes through the 1L1 indicator light in the first indicator lights 12 of the detection host 1, the 1# wire in the wire harness 16, the 2L1 indicator light in the second indicator lights 13 of the display 11, the D5 in the diodes of the display 11, and the 3# terminal in the output terminal 4 of the detection host 1 to complete the entire inspection process. If the wiring of the 1# wire in the wire harness 16 is correct, both the 1L1 indicator light in the first indicator lights 12 of the detection host 1 and the 2L1 indicator light in the second indicator lights 13 of the display 11 will be lit;
[0050] After the detection of the 1# wire loop in the wire harness 16 is completed and after a short delay, a high potential will also be output from the 2# terminal in the detection host 1 and pass through the 2L1 indicator light in the indicator light one 12 of the detection host 1, the 2# wire in the wire harness 16, the 2L2 indicator light in the indicator light two 13 of the display 11, the D5 in the diode of the display 11, and the 3# terminal in the output terminal 4 of the detection host 1 to complete the entire inspection process. If the 2# wire in the wire harness 16 is correctly connected, the 1L2 indicator light in the indicator light one 12 of the detection host 1 and the 2L2 indicator light in the indicator light two 13 of the display 11 will both be lit. The detection of the remaining wire harness 16 is carried out in the same way until the entire wire harness 16 is detected.
[0051] If the shutdown command is not received after the detection is completed, the detection host 1 will issue the detection command for the next cycle until the shutdown command is received.
[0052] If there is a damaged wire core in the wire harness 16, the corresponding indicator light on the indicator light two 13 of the display 11 will not be lit; if the indicator lights on the indicator light two 13 of the display 11 are not lit in sequence, the connection between the conductive part of the plug one 7 and the jack of the socket two 8 at both ends of the wire core in the wire harness 16 is incorrect.
