[0047] Inside the junction box housing: The negative terminal is also connected to the acoustic power supply capacitor; the positive terminal is also connected to the first pin of the acoustic power supply switch, and the second pin of the acoustic power supply switch is connected to the red terminal of the D1 cable terminal block group; the red terminal of the D1 cable terminal block group is also connected to the acoustic power supply capacitor, and the acoustic power supply capacitor is connected to the black terminal of the D1 cable terminal block group.

[0048] In the device shown in this embodiment, the decentralized wiring is changed to integrated wiring. For the wire replacement operations at various debugging stages of a certain type of equipment, the wiring principle is clarified, the overall layout of the circuit is determined according to the detection process, and with reliability as the center, the circuit control diagram is designed, and the function conversion switch is reasonably set to complete the relevant technical detections. To ensure the reliability of this detection wiring device, the selection and use of components are controlled, and components are selected according to national standards (GB) and national military standards (GJB). Then, considering the actual detection requirements of a certain type of equipment, the external shape structure of the junction box is optimized, and the junction box body, terminal blocks, and electrical connections are adjusted and optimized with the goals of light weight, convenience, and reliability. The key components such as the junction box body, terminal blocks, and filter capacitors are selected by comparison and optimization to improve the reliability of the product.

[0049] It can be understood that after the use of an external source assisted detection wiring device, the cable connection method during the detection process of a certain type of equipment will be improved, enabling the wiring operation to be completed in one go. Through reasonable design, the cable connection is made more reliable, and the existing capacitor box is integrated, and the technical detection items of a certain type of equipment can be completed by switching the switch. The use of this device is beneficial to optimizing human resources, standardizing personnel operations, reducing operation risks, and completing technical detection work safely and efficiently.

[0050] In specific practice, the wiring principle of this embodiment is as follows: The power supply cable of a certain type of equipment consists of the power supply cable D1, the control system power supply cable D4, and the primary battery activation cable DZ2. When a certain type of equipment is under debugging, steps such as power-on function detection, calibration parameter setting, turntable debugging, and joint debugging need to be carried out. The wiring status in each detection process is as follows:

[0051] When performing the power-on function detection of a certain type of equipment, the red and yellow wires of the D4 cable are connected to the positive power supply terminal, and the two black wires are connected to the negative power supply terminal. The yellow wire of the DZ2 cable is connected to the positive power supply terminal, and the red and black wires are left floating. The floating cable heads should be sleeved with sleeves respectively to prevent short-circuiting. For the wiring principle, refer to Figure 3 .

[0052] When the technical solution shown in this embodiment is used, after each terminal clamp is connected to the cable, rotate the changeover switch to "power-on voltage detection". At this time, the first pin and the third pin of the changeover switch are conducting, indicating that the yellow wire of the DZ2 cable is connected to the positive terminal of the power supply, and the red wire is suspended. The black wire represents the ground wire and can be either connected to the negative terminal or suspended.

[0053] When setting the calibration parameters of a certain type of equipment, the yellow wire of the D4 cable is connected to the positive terminal of the power supply, the two black wires are connected to the negative terminal of the power supply, and the red wire is suspended and protected with a sleeve. The red and yellow wires of the DZ2 cable are short-circuited and protected with a sleeve, and the black wire is connected to the negative terminal of the power supply. See Figure 4 .

[0054] When the technical solution shown in this embodiment is used, rotate the changeover switch to "normal debugging state". At this time, the second pin and the third pin of the changeover switch are conducting, indicating that the yellow wire and the red wire of the DZ2 cable are short-circuited. Since the red and yellow wires of the D4 cable are redundantly designed, whether the red wire of the D4 cable is suspended has no effect on the result.

[0055] When debugging the turntable of a certain type of equipment, the red and yellow wires of the D4 cable are connected to the positive terminal of the power supply, the two black wires are connected to the negative terminal of the power supply; the red and yellow wires of the DZ2 cable are short-circuited and protected with a sleeve, and the black wire is connected to the negative terminal of the power supply. See Figure 5 .

[0056] When the technical solution shown in this embodiment is used, rotate the changeover switch to "normal debugging state". At this time, the second pin and the third pin of the changeover switch are conducting, indicating that the yellow wire and the red wire of the DZ2 cable are short-circuited. At the same time, the two black wires of the D4 cable are connected to the negative terminal of the power supply, and the black wire of the DZ2 cable is connected to the negative terminal of the power supply.

[0057] When jointly debugging a certain type of equipment, the red and yellow wires of the D4 cable are connected to the positive terminal of the power supply, the black wire is connected to the negative terminal of the power supply; the red and yellow wires of the DZ2 cable are short-circuited, and the black wire is connected to the negative terminal of the power supply; the red wire of the D1 cable is connected to the positive terminal of the power supply, the black wire is connected to the negative terminal of the power supply, and a capacitor box needs to be connected to ensure the power supply capacity of the power supply. See Figure 6 .

[0058] When the technical solution shown in this embodiment is used, rotate the changeover switch to "normal debugging state". At this time, the second pin and the third pin of the changeover switch are conducting, indicating that the yellow wire and the red wire of the DZ2 cable are short-circuited. At the same time, close the acoustic power supply switch, and the wiring circuit during joint debugging can be achieved.

[0059] It should be noted that the external auxiliary detection wiring device further includes:

[0060] Acoustic power supply indicator light;

[0061] Inside the junction box housing: The second pin of the acoustic power supply switch is connected to the negative terminal through the acoustic power supply indicator light.

[0062] It should be noted that the external source auxiliary detection wiring device further includes:

[0063] A control power supply indicator light;

[0064] Inside the junction box housing: The positive terminal is connected to the negative terminal through the control power supply indicator light.

[0065] The inside of the junction box is divided into an acoustic part and a control part, each equipped with a power supply indicator light. The acoustic part has a large working current and is equipped with an acoustic power supply switch. During joint debugging, the acoustic power supply switch is placed in the "on" position. After use, the capacitor needs to be discharged. When the power is cut off, the acoustic power supply indicator light goes out, indicating that the discharge is complete. During the debugging of the control part, no acoustic power supply is required, and the acoustic power supply switch is placed in the "off" position.

[0066] It should be noted that for the technical solution shown in this embodiment, the technical parameters of its main components are:

[0067] The junction box housing is made of PET material, with dimensions of 160mm * 110mm * 90mm and a mass of 1 Kg.

[0068] The wire clamp adopts a compression spring type wire clamp head, with a carrying current of 50A.

[0069] Cable selection: The power supply cable uses FF46R - 2 1*2.5, and the acoustic and overall cables are AF - 2001*2.5.

[0070] The acoustic power supply switch adopts a 250V 30A push - type switch.

[0071] The acoustic power supply capacitor adopts a CD292 6800uf 35V capacitor.

[0072] Figure 7 These are the three - view drawings of the device shown in an exemplary embodiment of the present utility model, namely the front - view schematic diagram, the top - view schematic diagram, and the side - view schematic diagram. It can be seen that the junction box is composed of two groups of switches, cables, large capacitors, and wire clamps. The color and quantity of the wire clamps correspond one - to - one with the product cables (D1, D4, and DZ2). The internal cables of the junction box are connected to the wire clamps with screws and nuts. The total power supply cable is connected by an electrical connector (to prevent reverse connection).

[0073] The junction box realizes detections of items such as "power - on of the control system" and "debugging of the control system" by setting a switching rotary switch. During the debugging of the control system, the acoustic power supply switch is placed in the off position; during the joint debugging of a certain type of equipment, the acoustic power supply switch is placed in the on position.

[0074] The "switching knob" on the side of the junction box controls the disconnection and connection of the red and yellow cores of the DZ2 cable. When the switching knob is placed in the "power-on voltage detection" position, the yellow wire and the red wire of the DZ2 cable are in the disconnected state; when the switching knob is placed in the "normal debugging state", the yellow wire and the red wire of the DZ2 cable are in the connected state.

[0075] When the "switching knob" is turned to the normal debugging state, the connection relationship of the D4 cable is as follows: 04X1 (red, microcomputer), 04X2 (yellow, power) - positive terminal of the DC regulated power supply; 04X3 and 04X4 (black) - negative terminal of the DC regulated power supply. Connect the RD end (red) and YE end (yellow) of the DZ2 cable together, and connect the BK end (black) to the negative output terminal of the DC regulated power supply.

[0076] When the "switching knob" is turned to the power-on detection state, the YE end (yellow) of the DZ2 cable and the 04X2 (yellow, power) of the D4 cable - positive terminal of the DC regulated power supply; 04X3 and 04X4 (black) of the D4 cable - negative terminal of the DC regulated power supply.

[0077] The external source auxiliary detection wiring device shown in this embodiment has the following significances:

[0078] Improve quality and efficiency: The device adopts an integrated design, optimizes and integrates the decentralized wiring. Only one wiring is required, and the operation is convenient. Through the function conversion switch, the corresponding technical detection can be completed, avoiding frequent wire replacement operations, shortening the technical detection time of a certain type of equipment, reducing technical operators at the same time, and improving work efficiency.

[0079] Improve the reliability of the detection process: The external source auxiliary detection wiring device effectively avoids common faults such as self-checking abnormalities and power supply abnormalities of a certain type of equipment in the original wiring method, and also avoids potential safety hazards such as short circuits, loose connections, and component burnout caused by improper operation of personnel, improving the reliability of the detection process of a certain type of equipment.

[0080] Standardize the technical detection process: After using this device, the technical operator no longer needs to be forced to abort the equipment debugging process, replace the cable, restart the detection of a certain type of equipment and other cumbersome operations. Only by selecting through the function conversion switch can the relevant detection items be successfully completed. Therefore, while simplifying the personnel operation, the detection wiring device also makes the entire technical detection process of a certain type of equipment more standardized and orderly.
