Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing technology, specifically relating to a rapid circuit testing device. Background Technology
[0002] Many existing products include those with pin-type aviation connectors. The cables connected to the pin-type aviation connectors pass through the rear panel and connect to the micro switch of the sensing element. The cables pass through the cable guide holes in the rear panel from inside the product. During cable routing, the corresponding cables are placed in sequence and position, and after passing through the positioning plate, the cable leads connect to the element micro switch.
[0003] Due to space constraints during cable installation, the correctness of the wiring connections cannot be observed after initial placement, making it impossible to check the wiring integrity. A testing instrument and test bench are used to inspect all electrical properties of the product after all components are assembled. However, problems discovered during later finished product testing cannot be immediately rectified; the outer casing must be removed, and components above the cables, such as support frames and covers, must also be disassembled, resulting in lengthy disassembly times and potential damage to the appearance and threaded holes.
[0004] In the existing technology, cable wiring with pin-type aviation connectors is generally tested manually one by one using a multimeter. This not only wastes manpower, but also easily leads to missed or incorrect tests. Summary of the Invention
[0005] In order to solve the technical problems existing in the background art, the present invention provides a circuit rapid detection device that can quickly and accurately detect whether the cable wiring is correct.
[0006] The specific steps of this utility model are as follows: To achieve the above technical solution, this utility model provides a rapid circuit testing device, including a housing, an indicator light and a push-button switch embedded in the housing, a control circuit inside the housing, and a through hole on one side of the housing, through which the testing connector and testing pin are connected to the control circuit.
[0007] Furthermore, the testing connector is a 37-pin aviation connector.
[0008] Furthermore, the indicator light is a light-emitting diode.
[0009] Furthermore, the control circuit includes a power supply, the positive terminal of which is connected to the positive terminal of a light-emitting diode (LED), and the negative terminal of the LED is connected to a detection pin; the positive terminal of the power supply is connected to the detection connector via a push-button switch.
[0010] The beneficial effects of this utility model are: Connect the aviation connector (with a socket) to the corresponding aviation connector (with pins) of the device under test (DUT). Check the connection between the pins and the negative terminal of the DUT. When the socket in the aviation connector is correctly connected to the corresponding pin in the aviation connector of the DUT, the corresponding indicator light will illuminate. When one or more sockets in the aviation connector are incorrectly connected to one or more pins in the aviation connector of the DUT, one or more indicator lights will not illuminate. This indicates that the corresponding pins of the DUT have failed to form a circuit, thus enabling rapid detection and immediate correction of errors. This not only effectively prevents the waste of manpower and quality damage caused by disassembling parts, but also allows for quick and accurate detection of whether the cable wiring is correct.
[0011] The advantages of this invention in additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, each technical and scientific term used in this embodiment has the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model. They should not be construed as limiting this utility model.
[0018] In this utility model, terms such as "fixed connection," "connected," and "joined" should be interpreted broadly, indicating a fixed connection, an integral connection, or a detachable connection; a direct connection or an indirect connection through an intermediate medium. For researchers or maintenance personnel in this field, the specific meaning of the above terms in this utility model can be determined according to the specific circumstances, and should not be construed as a limitation of this utility model.
[0019] Example 1: like Figure 1 and Figure 2 As shown, this embodiment provides a rapid circuit testing device, including: a housing 1, with indicator lights 2 and push-button switches 6 embedded in the panel of the housing 1, and a control circuit disposed inside the housing 1; a through hole is provided on one side of the housing 1, through which a test connector 3 and a test pin 4 are connected to the control circuit; wherein, the test connector is an aviation connector, such as a 37-pin aviation connector, using pins 2, 6, 9, 10, 14, 18, 21, and 25; the number of indicator lights is the same as the number of pins in the aviation connector connected to test leads. For example, if a 37-pin aviation connector has seven pins connected to test leads connected to the control circuit, the number of indicator lights is seven, and each indicator light is marked with a number, such as 1 to 7. The indicator lights are light-emitting diodes.
[0020] The control circuit includes a power supply 7, the positive terminal of which is connected to the positive terminal of a light-emitting diode (LED), and the negative terminal of the LED is connected to the detection pin 4. The positive terminal of the power supply is connected to the detection connector 3 via a push-button switch 6. The power supply uses a 9V multilayer battery.
[0021] Specifically, in this embodiment, during use, the aviation connector (with a socket) is plugged into the aviation connector (with pins) of the corresponding device under test (DUT). The connection between the pins and the negative terminal of the DUT is checked. The button is turned off. When the socket in the aviation connector is correctly connected to the corresponding pin circuit in the aviation connector of the DUT, the corresponding indicator light will illuminate. When one or more sockets in the aviation connector are incorrectly connected to one or more corresponding pin circuits in the aviation connector of the DUT, one or more of the corresponding indicator lights will not illuminate, indicating that the corresponding pin of the DUT has failed to form a circuit. This allows for quick detection and immediate correction of errors, effectively preventing the waste of manpower and quality loss caused by disassembling parts.
[0022] Example 2: This embodiment provides another rapid circuit detection device, which differs from Embodiment 1 in that, as Figure 3 As shown, the control circuit includes: a single-pole double-throw analog switch and a microcontroller, which is an MSP430 microcontroller; the P0.0 pin of the microcontroller is connected to the output of the AND gate; Before testing, connect the battery cells at one end of the cable to be tested to a single-pole double-throw analog switch, and connect all the battery cells at the other end. When testing one battery cell, close the switch to GND. Under normal circumstances, the voltage of one battery cell will be pulled low and sent to the AND gate logic circuit for testing. The AND gate logic circuit then sends the voltage to the microcontroller for processing and testing. The result is sent to the microcontroller for processing and judgment. If it is low level, it proves that there is no problem. If it is high level, it proves that there is an open circuit. The microcontroller stores the data. After all tests are completed, the data is sent to the LCD screen for display.
[0023] The same or similar parts between the various embodiments in this specification can be referred to mutually. In particular, the terminal embodiments are basically similar to the method embodiments, so the description is relatively simple, and the relevant parts can be referred to the description in the method embodiments.
[0024] The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.
[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
