Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment testing, specifically a signal circuit micro-interrupt device. Background Art
[0002] Micro-interruption tests in circuits primarily simulate poor circuit contact. This occurs when dust, foreign objects, or metal oxidation cause a complete break in the circuit connection, or an abnormally increased resistance, preventing the appliance or circuit from functioning properly. In daily life, lights failing to turn on or flickering, or computers failing to start, are usually due to poor circuit contact and current obstruction. More serious issues can lead to short circuits, such as two points with different potentials coming into direct contact or being short-circuited by an impedance. In such cases, the current is very high, potentially damaging electrical equipment or even causing a fire.
[0003] With the increasing number and usage of electronic and electrical devices, and the widespread use of both gasoline-powered and electric vehicles, especially new energy electric vehicles, the presence of battery systems makes them highly susceptible to fires and even explosions in the event of a short circuit. To reduce the occurrence of such situations, micro-interruption testing can be incorporated into the product development phase. Utility Model Content
[0004] The purpose of this invention is to provide a micro-interruption device for signal circuits to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a signal circuit micro-interruption device, including a relay and a voltage drop simulator;
[0006] The relay includes control signal connection ports A1 and A2. Connection port A1 is connected to the negative terminal of the voltage drop simulator, and connection port A2 is connected to the positive terminal of the voltage drop simulator.
[0007] The relay also includes an input port NO and an output port COM. The input port NO is connected to the load input, and the output port COM is connected to the load output.
[0008] Preferably, the relay model selected is: SSK10D6132
[0009] Preferably, the voltage drop simulator selected is the VDS 200Q10.1-230.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] This invention can simulate the performance of signal circuits and load circuits under poor contact conditions. This device is simple to operate, low in cost, and does not require an additional controller. The voltage drop simulator itself is also a commonly used device in laboratories in the field of equipment testing and can be used directly. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the circuit principle of this utility model. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0014] Please refer to the figure. This embodiment provides a signal circuit micro-interruption device, including a relay and a voltage drop simulator; the selected relay model is SSK10D6132. The selected voltage drop simulator model is VDS200Q10.1-230.
[0015] The relay includes control signal connection ports A1 and A2. Connection port A1 is connected to the negative terminal of the voltage drop simulator, and connection port A2 is connected to the positive terminal of the voltage drop simulator.
[0016] The relay also includes an input port NO and an output port COM. The input port NO is connected to the load input, and the output port COM is connected to the load output.
[0017] In practical use, the control signal lines A1 and A2 of the relay are controlled by the voltage drop simulator. When there is voltage at terminals A1 and A2, NO and COM are in the closed state; when there is no voltage at A1 and A2, NO and COM are in the open state. Thus, by changing the on / off state of the voltage at terminals A1 and A2, a micro-interruption test of the load circuit can be achieved.
[0018] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
