Abstract
Description
Technical Field
[0001] This utility model relates to the field of socket testing technology, and in particular to a socket testing instrument. Background Technology
[0002] A socket tester is a support device for testing socket wiring. When installing a socket, internal wiring is required, including live wire, neutral wire, and ground wire. The wiring must be done correctly, otherwise a short circuit may occur, causing damage to the socket. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of socket testers.
[0003] Existing socket testers have certain drawbacks. First, they cannot easily and quickly detect whether the internal wiring of a socket is accurate. Incorrect wiring of the live wire, neutral wire, and ground wire can lead to short circuits and even fires, which has a certain adverse effect on actual use. Therefore, we propose a new socket tester. Utility Model Content
[0004] Technical problem solved: In view of the shortcomings of the prior art, this utility model provides a socket tester. Based on the circuit path under different line connection states and the connection relationship between the indicator lights and each line, the tester observes whether the socket wiring is accurate by observing the changes of three sets of indicator lights. This method is convenient and fast and can effectively solve the problems in the background art.
[0005] Technical Solution: To achieve the above objectives, the technical solution adopted by this utility model is as follows: a socket tester, comprising a socket body, a first wire positioned around the perimeter of the socket body, a second wire and a third wire installed at the center of the socket body, a first LED module, a second LED module and a third LED module installed at the front of the socket body, terminals positioned at the ends of the first wire, the first LED module, the second wire, the second LED module and the third LED module, a first resistor connected between the first LED module and the second wire, a second resistor connected between the third wire and the second LED module, and a third resistor connected between the third wire and the third LED module, wherein the first resistor, the second resistor and the third resistor are one of a color ring resistor with solder holes and a chip resistor with solder pads, and the first LED module, the second LED module and the third LED module each have three color states: gray, red and white.
[0006] Preferably, a detection and processing mechanism is installed inside the socket body. The detection and processing mechanism is equipped with a first indicator light status detector, a second indicator light status detector, a third indicator light status detector, a communicator, a data processor, a display, and an alarm. The output terminals of the first indicator light status detector, the second indicator light status detector, and the third indicator light status detector are connected to the input terminal of the data processor through the communicator. The output terminal of the data processor is connected to the input terminal of the display and the alarm.
[0007] Preferably, when the socket body is properly wired, the first LED module, the second LED module, and the third LED module display white, red, and red, respectively. When the socket is wired correctly, the live wire has a normal voltage to the neutral wire and the ground wire. The internal circuit of the detector causes the indicator lights connected between the live wire and the neutral wire, and between the live wire and the ground wire to conduct and light up. One red light is connected across the neutral wire and the live wire and conducts and lights up during the positive half-cycle of the AC current. The other red light is connected across the live wire and the ground wire and will also light up due to the voltage difference. The white indicator light is not connected to the conducting circuit and therefore does not light up, indicating that the circuit connection is normal.
[0008] Preferably, when the socket body is open-circuited, the first LED module, the second LED module, and the third LED module display white, red, and white respectively, indicating that the grounding contact is not connected. This means that the ground wire is not properly connected to the circuit. At this time, there is voltage between the live wire and the neutral wire, causing the red light connected across the neutral and live wires to light up. However, since the ground wire is not connected, a normal circuit cannot be formed between the live wire and the ground wire. The white indicator light connected across the live wire and the ground wire does not light up, and the other white indicator light is also not connected to the conducting circuit, thus displaying a white, red, and white state, indicating that there is a grounding problem.
[0009] Preferably, when the neutral wire of the socket body is open, the first LED module, the second LED module, and the third LED module display white, white, and red, respectively. The neutral wire contact is not connected, that is, the neutral wire is disconnected. The live wire has voltage to the ground wire, causing the red light connected across the live wire and the ground wire to light up. However, because the neutral wire is open, a normal circuit cannot be formed between the live wire and the neutral wire. The white indicator light connected across the neutral wire and the live wire does not light up, and the other white indicator light is also not connected to the conducting circuit. Therefore, the display shows white, white, and red, indicating that the neutral wire connection is abnormal.
[0010] Preferably, when the live wire of the socket body is open, the first LED module, the second LED module, and the third LED module will display white, white, white, indicating that the live wire contact is not connected, i.e., the live wire is disconnected. At this time, there is no voltage between the live wire and the neutral wire and the ground wire, and all indicator lights cannot form a conductive circuit. Therefore, the three white indicator lights will not light up and will display white, white, white, indicating that the live wire is not properly connected.
[0011] Preferably, when the socket body is reversed between live and ground, the first LED module, the second LED module, and the third LED module will display gray, white, and red, respectively. The live wire and the ground contact are interchanged. The place where the live wire should be connected is connected to the ground wire, and the place where the ground wire should be connected is connected to the live wire. At this time, the live wire after the incorrect connection is actually the ground wire, thus displaying a combination of gray, white, and red.
[0012] Preferably, when the live and neutral wires of the socket body are reversed, the first LED module, the second LED module, and the third LED module will display gray, red, and white, respectively. The live wire and neutral wire contacts will be interchanged. After the incorrect connection, the place that was originally connected to the live wire will be connected to the neutral wire, and the place that was originally connected to the neutral wire will be connected to the live wire, and the display will show gray, red, and white.
[0013] Beneficial Effects: Compared with existing technologies, this utility model provides a socket tester with the following beneficial effects: This socket tester, based on the circuit path under different wiring connection states and the connection relationship between indicator lights and each line, observes the accuracy of socket wiring through the changes of three sets of indicator lights. It is convenient and quick. When the wiring is normal, the indicator lights display white, red, and red. When the socket wiring is correct, the live wire has normal voltage to the neutral and ground wires. The internal circuit of the detector causes the indicator lights connected between the live and neutral wires and between the live and ground wires to conduct and illuminate. One red light is connected across the neutral and live wires and illuminates during the positive half-cycle of AC power; another red light is connected across the live and ground wires and also illuminates due to the voltage difference. The white indicator light is not connected to the conducting circuit and therefore does not light up, indicating that the wiring connection is normal. The entire socket tester has a simple structure, is easy to operate, and its performance is better than traditional methods. Attached Figure Description

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] like Figure 1-4As shown, a socket tester includes a socket body 1. A first wire 2 is positioned around the perimeter of the socket body 1. A second wire 3 and a third wire 4 are installed near the center of the socket body 1. A first LED module 6, a second LED module 7, and a third LED module 8 are installed near the front of the socket body 1. Terminals 11 are positioned at the ends of the first wire 2, first LED module 6, second wire 3, second LED module 7, and third LED module 8. A first resistor 5 is connected between the first LED module 6 and the second wire 3. A second resistor 10 is connected between the third wire 4 and the second LED module 7. A third resistor 9 is connected between the third wire 4 and the third LED module 8. The first resistor 5, second resistor 10, and third resistor 9 are either color-coded resistors with solder holes or surface-mount resistors with solder pads. The first LED module 6, second LED module 7, and third LED module 8 each have three color states: gray, red, and white. Based on the circuit path under different wiring connection states and the connection relationship between the indicator lights and each wire, the accuracy of the socket wiring can be observed through the changes of the three sets of indicator lights, providing a convenient and quick method.
[0023] Furthermore, a detection and processing mechanism 12 is installed inside the socket body 1. The detection and processing mechanism 12 is equipped with a first indicator light status detector 13, a second indicator light status detector 14, a third indicator light status detector 15, a communicator 16, a data processor 17, a display 18, and an alarm 19. The output terminals of the first indicator light status detector 13, the second indicator light status detector 14, and the third indicator light status detector 15 are connected to the input terminal of the data processor 17 through the communicator 16. The output terminal of the data processor 17 is connected to the input terminals of the display 18 and the alarm 19.
[0024] Furthermore, when the socket body 1 is properly wired, the first LED module 6, the second LED module 7, and the third LED module 8 will display white, red, and red respectively. When the socket is wired correctly, there is normal voltage between the live wire, the neutral wire, and the ground wire. The internal circuit of the detector causes the indicator lights connected between the live wire and the neutral wire, and between the live wire and the ground wire to conduct and light up. One of the red lights is connected across the neutral wire and the live wire and conducts and lights up during the positive half-cycle of the AC current. The other red light is connected across the live wire and the ground wire and will also light up due to the voltage difference. The white indicator light is not connected to the conducting circuit and therefore does not light up, indicating that the circuit connection is normal.
[0025] Furthermore, when the socket body 1 is open-circuited, the first LED module 6, the second LED module 7, and the third LED module 8 will display white, red, and white respectively. The grounding contact is not connected, which means that the ground wire is not properly connected to the circuit. At this time, there is voltage between the live wire and the neutral wire, causing the red light connected across the neutral and live wires to light up. However, since the ground wire is not connected, a normal circuit cannot be formed between the live wire and the ground wire. The white indicator light connected across the live wire and the ground wire will not light up, and the other white indicator light is also not connected to the conducting circuit, thus displaying the white, red, and white status, indicating that there is a grounding problem.
[0026] Furthermore, when the neutral wire of the socket body 1 is open, the first LED module 6, the second LED module 7, and the third LED module 8 will display white, white, and red respectively. The neutral wire contact is not connected, that is, the neutral wire is disconnected. The live wire has voltage to the ground wire, causing the red light connected across the live wire and the ground wire to light up. However, because the neutral wire is open, a normal circuit cannot be formed between the live wire and the neutral wire. The white indicator light connected across the neutral wire and the live wire will not light up. The other white indicator light is also not connected to the conducting circuit, so it displays white, white, and red, indicating that the neutral wire connection is abnormal.
[0027] Furthermore, when the live wire of the socket body 1 is open, the first LED module 6, the second LED module 7, and the third LED module 8 will display white, white, white, indicating that the live wire contact is not connected, i.e., the live wire is disconnected. At this time, there is no voltage between the live wire and the neutral wire and the ground wire, and all indicator lights cannot form a conductive circuit. Therefore, the three white indicator lights will not light up and will display white, white, white, indicating that the live wire is not properly connected.
[0028] Furthermore, when the live and ground wires of the socket body 1 are reversed, the first LED module 6, the second LED module 7, and the third LED module 8 will display gray, white, and red respectively. The live wire and the ground contact are swapped. The place where the live wire should be connected is connected to the ground wire, and the place where the ground wire should be connected is connected to the live wire. At this time, the live wire after the incorrect connection is actually the ground wire, thus displaying a combination of gray, white, and red.
[0029] Furthermore, when the live and neutral wires of the socket body 1 are reversed, the first LED module 6, the second LED module 7, and the third LED module 8 will display gray, red, and white, respectively. The live wire and neutral wire contacts are swapped. After the incorrect connection, the place that was originally connected to the live wire is connected to the neutral wire, and the place that was originally connected to the neutral wire is connected to the live wire, and the display will show gray, red, and white.
[0030] Working principle: This utility model includes a socket body 1, a first wire 2, a second wire 3, a third wire 4, a first resistor 5, a first LED module 6, a second LED module 7, a third LED module 8, a third resistor 9, a second resistor 10, a wiring terminal 11, a detection and processing mechanism 12, a first indicator light status detector 13, a second indicator light status detector 14, a third indicator light status detector 15, a communicator 16, a data processor 17, a display 18, and an alarm 19. Based on the circuit path under different line connection states and the connection relationship between the indicator lights and each line, the accuracy of the socket wiring can be observed through the changes of the three sets of indicator lights, which is convenient and quick.
[0031] Normal wiring
[0032] The indicator lights show: white, red, red.
[0033] Principle: When the socket is wired correctly, there is a normal voltage between the live wire, neutral wire, and ground wire. The detector's internal circuitry causes the indicator lights connected between the live and neutral wires, and between the live and ground wires, to illuminate. One red light is connected across the live and neutral wires and illuminates during the positive half-cycle of the AC current; the other red light is connected across the live and ground wires and also illuminates due to the voltage difference. The white indicator light is not connected to the conducting circuit and therefore does not light up, indicating that the wiring connection is normal.
[0034] Grounding open circuit
[0035] Indicator lights display: white, red, white.
[0036] Principle: If the grounding contact is not connected, it means that the ground wire is not properly connected to the circuit. At this time, there is voltage between the live wire and the neutral wire, causing the red light connected across the live and neutral wires to light up; however, because the ground wire is not connected, a normal circuit cannot be formed between the live wire and the ground wire, so the white indicator light connected across the live and ground wires does not light up, and the other white indicator light is also not connected to the conducting circuit, thus displaying a white, red, white status, indicating that there is a grounding problem.
[0037] Neutral wire open circuit
[0038] The indicator lights show: white, white, and red.
[0039] Principle: The neutral wire contact is not connected, meaning the neutral wire is open. The live wire has voltage to the ground wire, causing the red indicator light connected between the live and ground wires to illuminate. However, because the neutral wire is open, a normal circuit cannot be formed between the live and neutral wires, so the white indicator light connected between the live and neutral wires does not light up. The other white indicator light is also not connected to the conducting circuit, resulting in a white-white-red display, indicating an abnormal neutral wire connection.
[0040] Opening the way in fire
[0041] The indicator light shows: white, white, white.
[0042] Principle: The live wire contact is not connected, meaning the live wire is disconnected. At this time, there is no voltage between the live wire and the neutral and ground wires, and all indicator lights cannot form a conductive circuit. Therefore, the three white indicator lights do not light up, displaying white, white, white, indicating that the live wire is not properly connected.
[0043] Fire-ground reverse connection
[0044] Indicator lights display: gray, white, red.
[0045] Principle: The live wire and ground contact are swapped. A ground wire is connected where a live wire should be, and a live wire is connected where a ground wire should be. In this situation, the incorrectly connected "live wire" (actually a ground wire) has a voltage across the neutral wire, causing the red indicator light connected between the neutral and "live wire" to illuminate. Meanwhile, the actual live wire (the ground wire actually connected) has no normal voltage across the neutral wire, so the white indicator light connected between them does not illuminate. Additionally, a gray indicator light illuminates to indicate a detected abnormal connection between the live and ground wires, thus displaying a combination of gray, white, and red.
[0046] Reverse polarity of live and neutral
[0047] Indicator lights display: gray, red, white.
[0048] Principle: The live and neutral wire contacts are swapped. After the incorrect connection, the place that was originally connected to the live wire is connected to the neutral wire, and the place that was originally connected to the neutral wire is connected to the live wire. At this time, the incorrectly connected "live wire" (actually the neutral wire) has a certain voltage to the ground wire, causing the red light connected between the "live wire" and the ground wire to light up; while the real live wire (the actual connected neutral wire) has no normal voltage between the ground wire, and the white indicator light connected between the two does not light up; at the same time, the gray indicator light lights up to indicate that an abnormal connection between the live and neutral wires has been detected, displaying a gray, red, and white status.
