DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0047] The core of the utility model is to provide a constant current source detection device and a detection system to improve the constant current source detection efficiency and safety, while extending the service life of the detection device.

[0048] Figure 1 A structural diagram of a constant current source provided in an embodiment of the present application, such as Figure 1As shown, there are multiple electrical interfaces in the constant current source: power interface (CN1: 1, 2 (L phase interface); CN1: 3, 4 (N phase interface), CN1: 5, 6 (GND)), power output port (CN2: 1, 2, 3 (positive output terminal); CN2: 4, 5, 6 (negative output terminal)), power control port (CN3: 1, 2) for controlling the power on and off of the constant current source, normal signal output port (CN3: 3, CN3: 4) for outputting normal signal, fault signal output port (CN3: 7, CN3: 8) for outputting fault signal, current regulation port (CN3: 5, 6) for receiving current regulation signal and reset port for eliminating fault signal and restoring the initial setting of the module. In the specific work, in order to ensure that the backup constant current source is available when needed, the backup constant current source needs to be regularly tested. At present, most of the detection methods for standby constant current sources are to install the standby constant current source and determine the working state of the standby constant current source by judging whether the electronic system is working normally. However, due to the large number of on-board electrical components and complex circuits involved in the installation process, the detection efficiency is too low, and it is easy to cause equipment damage due to operational errors. If an external detection circuit is used to detect the constant current source, the detection device will be exposed to high temperature, high humidity, and high salt fog environment for a long time, which will easily cause corrosion, mildew, rust, short circuit and other problems in the detection circuit, seriously affecting the service life and normal use of the detection device. In order to solve this technical problem, the present application provides a new constant current source detection device, which is connected to the electrical interface of the constant current source to be tested through the wiring terminal 4 by the control element 2 and the indicator light arranged on the outer surface of the detection box 1, so that the constant current source to be tested does not need to be installed when the installation operation is performed, thereby improving the detection efficiency and safety. At the same time, the pins of the control element 2, the pins of the display element 3, the wires 5 connected thereto, the wiring terminal 4, etc. are all arranged inside the detection box 1 to prevent environmental factors such as high temperature, high humidity, and high salt fog from causing the detection circuit to lose and extend the service life of the detection device.

[0049] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Figure 2 A structural diagram of a constant current source detection device provided in an embodiment of the present application, such as Figure 2 As shown, the constant current source detection device includes: a detection box 1, a control element 2, a display element 3 and a terminal 4 arranged on the outer surface of the detection box 1; the pins of the control element 2 and the display element 3 are all arranged on the inner surface of the detection box 1, and are connected to the terminal 4 through a wire 5; the terminal 4 is used to connect to the electrical interface of the constant current source to be tested; the detection box 1 includes a box body 6 and a box cover 7 for accommodating the wire 5 and the terminal 4; the display element 3 is used to obtain and display the detection result of the constant current source to be tested.

[0051] Figure 3 A top view of a box body 6 of a constant current source detection device provided in an embodiment of the present application, Figure 4 A bottom view of a box body 6 provided in an embodiment of the present application, as shown in FIG. Figures 2 to 4 As shown in any of the accompanying drawings, the outer surface of the detection box 1 to which each control element 2 and display element 3 is fixed can be any surface (side surface or top surface, etc.) of the detection box 1, and is not limited here. The side box wall and the top box wall of the detection box 1 can be provided with channel holes, and the control element 2, the display element 3, etc. are fixed on the outer surface of the detection box 1, and the pins of the elements enter the interior of the detection box 1 through the channel holes and are fixed on the inner surface of the detection box 1. Figure 5 A schematic diagram of the use of a constant current source detection device provided in an embodiment of the present application, wherein the pins of each component are connected to the wiring terminal 4 through a wire 5, and are connected to the electrical interface of the constant current source through the wiring terminal 4 to achieve communication with the constant current source.

[0052] In a specific implementation, the control element 2 and the display element 3 are used to connect to the electrical interface of the constant current source to be measured (i.e. Figure 1 The control element 2 is connected to the electrical interface of the constant current source, and when the control element 2 is connected to the electrical interface of the constant current source, the constant current source can be powered or input with a control signal through the pin to realize the detection of the constant current source. The display element 3 is used to display the detection result of the constant current source. During the detection process, if the constant current source works normally, the normal signal interface (CN3:3, CN3:4) outputs a high-level signal. If the constant current source is in a fault state, the fault signal interface (CN3:7, CN3:8) outputs a high-level signal. The display element 3 displays the detection result according to the received high-level signal. In a specific implementation, the display element 3 can be an LED display screen, or a buzzer or an indicator light, etc., which is not limited here.

[0053] Figure 6 A structural diagram of a wiring terminal provided in an embodiment of the present application, such as Figure 6 As shown, the detection device reasonably designs the wiring terminals 4 (port adapter row) connected to the power supply and the electrical interface according to the size of the external electrical port of the constant current source. When the constant current source to be tested is tested, it is not necessary to connect the external electrical ports of the constant current source with the wires 5 one by one. The port adapter row, one end of which has been respectively connected to the components of the constant current source detection device, can be directly inserted into the external electrical port of the corresponding constant current source.

[0054] In a specific implementation, the detection box 1 composed of the box body 6 and the box cover 7 is used to protect the internal detection circuit and the wires 5, the connection terminals 4 and other components from environmental influences. The box cover 7 and the box body 6 can be connected by hinges 8, hinges, etc., or can be split, which is not limited here.

[0055] In the technical solution provided in the present application, an external power supply can be used to power the detection box 1, that is, the external electrical interface of the constant current source is connected to the detection device, and the detection box 1 is switched for power supply. The external electrical interface of the constant current source can also be connected to the detection device, and the constant current source is independently powered, or the external electrical interface of the constant current source is short-circuited, and the constant current source is powered to achieve the purpose of powering the detection device. If the solution of "the external electrical interface of the constant current source is connected to the detection device, and the constant current source is independently powered" is selected, the constant current source detection device does not need to be connected to the power supply, and a 220V AC power is directly connected to the constant current source. If the "constant current source electrical interface is short-circuited, and the constant current source is independently powered" is adopted, the constant current source detection device is no longer needed, but this approach has high safety risks.

[0056] In other application scenarios, other interfaces may need to be used, so a channel hole may be reserved on the detection box 1. When in use, the detection personnel place the required functional module components through the channel hole according to the needs of the actual application scenario to realize the detection of the constant current source.

[0057] The present embodiment provides a constant current source detection device, including a detection box, a control element, a display element and a wiring terminal arranged on the outer surface of the detection box; the pins of the control element and the display element are all arranged on the inner surface of the detection box, and are connected to the wiring terminal through a wire; the wiring terminal is used to connect to the electrical interface of the constant current source to be tested; the detection box includes a box body and a box cover for accommodating the wires and the wiring terminal; the display element is used to obtain and display the detection results of the constant current source to be tested. It can be seen that in the technical solution provided by the present application, the control element and the indicator light arranged on the outer surface of the detection box are connected to the electrical interface of the constant current source to be tested through the wiring terminal, so that when the constant current source to be tested is tested, there is no need for installation operation, thereby improving the detection efficiency and safety. At the same time, the pins of the control element, the pins of the display element and the wires and wiring terminals connected thereto are all arranged inside the detection box to prevent environmental factors such as high temperature and high humidity from causing loss of the detection circuit, thereby extending the service life of the detection device.

[0058] In a specific implementation, the detection of the constant current source focuses on detecting whether the output current of the constant current source meets the conditions by inputting current into the constant current source. The judgment of the output current of the constant current source can be realized by an external device or by the constant current source itself. In this embodiment, in order to reduce the cost of equipment, the method of detecting the output current by the constant current source itself is selected. The display unit directly obtains the detection result of the constant current source output. Figure 7 A schematic diagram of a control element and a display element provided in an embodiment of the present application, such as Figure 7As shown, the constant current source interface commonly used in the detection process includes a power interface, a power output port, a power control port, a normal signal output port, a fault signal output port, a current regulation port, a reset port, etc. Correspondingly, in this embodiment, the control element 2 includes: a reset switch 21, a circuit protection element 22, a start-stop switch 23 and a current regulator 24, and the display element 3 includes: a normal indicator light 31 and a fault indicator light 32. Among them, the reset switch 21 is used to connect to the reset interface of the constant current source to be tested through the wiring terminal 4; the first end of the circuit protection element 22 is connected to the power supply, and the second end of the circuit protection element 22 is used to connect to the power supply interface of the constant current source to be tested through the wiring terminal 4 to supply power to the constant current source to be tested; the start-stop switch 23 is used to connect to the switch of the constant current source to be tested through the wiring terminal 4; the current regulator 24 is used to connect to the current regulation interface of the constant current source to be tested through the wiring terminal 4; the normal indicator light 31 is used to connect to the normal signal interface of the constant current source to be tested through the wiring terminal 4 to obtain and display the normal working signal; the fault indicator light 32 is used to connect to the fault signal interface of the constant current source to be tested through the wiring terminal 4 to obtain and display the fault signal. Among them, the circuit protection element 22 is used to prevent the voltage in the detection device from being too high and causing the device to burn out. The circuit protection element 22 can be a protection circuit or a fuse.

[0059] In a specific implementation, the main structure of the detection device is a box body 6, and six channel holes are designed on the front panel of the box body 6 (the channel holes can be realized by spot drilling and hole expansion methods), which are respectively used to place the reset switch 21, the circuit protection element 22, the start-stop switch 23, the current regulator 24, the normal indicator light 31 and the fault indicator light 32. The difference between these channel holes is that since the fixed components are of different sizes, the corresponding channel holes have different apertures. Holes can be punched according to the required component size to ensure the same size. The box body 6 is designed with a flip cover, and the rear panel of the flip cover is connected to the rear panel of the box body 6 by 4 screws and hinges respectively. It can be covered when not in use, and the wires 5 connecting the six components are stored and placed in the box body 6 so that the whole device looks beautiful. When testing the constant current source to be tested, usually the 220V AC is first connected to the antenna of the power fuse holder on the detection device, and then connected to the two power interfaces CN1:1,2 (L) and CN1:3,4 (N) of the constant current source; the connection line of the start-stop switch 23 is connected to the two interfaces CN3:1 and CN3:2 respectively; the connection line of the normal indicator light 31 is connected to the two interfaces CN3:3 and CN3:4 respectively, so as to observe whether the constant current source is running normally, and realize the power-on and power-off functions by toggling the switch; Figure 1It can be seen that the two interfaces CN3:5 and CN3:6 must be connected so that the entire circuit can be turned on, so the connection line of the current regulator 24 is connected to the two interfaces CN3:5 and CN3:6 respectively to ensure that the entire circuit is a closed loop; the connection line of the fault indicator light 32 is connected to the two interfaces CN3:7 and CN3:8 respectively; the connection line of the reset switch 21 is connected to the two interfaces CN3:9 and CN3:10 respectively.

[0060] In a specific implementation, since different models of constant current sources to be tested have different standards, the components used in the test are also different. In order to improve the versatility of the constant current source detection device, the constant current source detection device also includes a spare interface; the spare interface includes an external interface and an internal interface; the internal interface and the external interface are connected through a channel hole set on the detection box 1; the external interface is used to connect with the spare test element; wherein the spare test element is determined according to the electrical information of the constant current source to be tested. The tester selects the corresponding spare test element according to the particularity of the constant current source to be tested, and connects the spare test element to the spare interface to realize the constant current source test. The number of spare interfaces can be multiple, and they are evenly distributed on the inner surface of the test device.

[0061] In a specific implementation, the box body 6 and the box cover 7 of the constant current source detection device detection box 1 are connected by a hinge 8, and the hinge 8 includes a first hinge element, a second hinge element and a hinge shaft; a first sleeve is provided on the first side of the first hinge element, and the second side of the first hinge element is fixed to the upper side of the box cover; a second sleeve is provided on the first side of the second hinge element, and the second side of the second hinge element is fixed to the side of the box body; the hinge shaft is passed through the first sleeve and the second sleeve to connect the first hinge element and the second hinge element.

[0062] Figure 8 A schematic diagram of a magnetic sticker of a constant current source detection device box provided in an embodiment of the present application, Fig. 9 A schematic diagram of a magnetic sticker on a box cover of a constant current source detection device provided in an embodiment of the present application; Figure 8 and Fig. 9 As shown, a rectangular groove 9 is designed on the contact surface between the detection device and the flip cover when it is closed, for pasting the magnetic sticker 10. After assembling the required components, sealant is applied at the contact position between the components and the box body 6 to improve the sealing of the device.

[0063] Since the power fuse holder inside the detection device needs to be connected to AC 220V electricity, 3mm thick insulating rubber is pasted on the internal surfaces of the detection device, and heat shrink tubes are put on the soldering parts of each component to ensure the insulation performance of the detection device and ensure safety.

[0064] In the specific implementation, in order to further improve the service life of the detection device, it is also necessary to select corrosion-resistant materials to make the detection box 1. Through the material anti-corrosion comparison experiment, the detection box 1 of the constant current source detection device is made of Al-Mg alloy. The specific Al-Mg alloy is 5A02 aluminum alloy, and its chemical composition is shown in the following table.

[0065] Table 1

[0066]

[0067] This alloy is the most widely used rust-proof aluminum with good corrosion resistance, excellent welding performance, good cold processing performance, and medium strength. The use of aluminum-magnesium alloy not only has a lighter weight, better cold processing performance and moderate mechanical strength, but also is conducive to the heat dissipation and corrosion protection of the detection device, and has a high cost performance. In addition, other corrosion-resistant materials can also be selected for redesign, such as carbon fiber, copper oxide, wooden box body 6, etc., but they are not as good as aluminum alloy in terms of economy, processing difficulty, and fall resistance, which is not conducive to the promotion and long-term use of constant current source detection devices.

[0068] In a specific implementation, a corrosion-resistant coating may be coated on the outer surface of the detection box 1 to further improve the corrosion resistance of the detection box 1 .

[0069] In addition, the present application also provides a constant current source detection system, the above-mentioned constant current source detection device, wherein the constant current source detection device includes a detection box, a control element, a display element and a terminal arranged on the outer surface of the detection box; the pins of the control element and the display element are all arranged on the inner surface of the detection box, and are connected to the terminal through a wire; the terminal is used to connect to the electrical interface of the constant current source to be tested; the detection box includes a box body and a box cover for accommodating the wire and the terminal; the display element is used to obtain and display the detection result of the constant current source to be tested. It can be seen that in the technical solution provided by the present application, the control element and the indicator light arranged on the outer surface of the detection box are connected to the electrical interface of the constant current source to be tested through the terminal, so that when the constant current source to be tested is tested, there is no need for installation operation, thereby improving the detection efficiency and safety. At the same time, the pins of the control element, the pins of the display element and the wires, terminals, etc. connected thereto are all arranged inside the detection box to prevent environmental factors such as high temperature and high humidity from causing loss of the detection circuit and extend the service life of the detection device.
