Description

Technical Field

[0001] This utility model relates to a grounding detector, and more particularly to a grounding detector used to detect whether an object is grounded and whether the object is conductive. Background Technology

[0002] Electrons are ubiquitous in life, and the human body, like a capacitor, has the function of storing electric charge. Therefore, it is easy for static electricity to accumulate on the body, and even the cells in the body can generate their own charge. Currently, many scientific studies and traditional Chinese medicine theories indicate that frequent contact with the earth can improve sleep quality and stabilize emotions. The principle behind this is that contact with the earth helps to expel excess electric charge from the body.

[0003] Therefore, the creator has developed many creations with conductive effects and the ability to connect to the ground, such as Taiwan Patent No. M614030 "Bedding with Potential Balance". The abstract of this patent describes a bedding with potential balance, which is made of at least one conductive cloth that has been cut and assembled. The conductive cloth is provided with multiple sets of conductive yarns and fiber filaments that are interlaced with warp and weft. The conductive cloth is connected to a wire, and the wire is connected to a ground. When in use, the positive charge of the human body or the static electricity generated by the human body is transferred to the ground through the conductive cloth via the wire, thereby achieving the effect of human body potential balance.

[0004] However, during the use of the aforementioned conductive cloth, there may be situations where the wires appear to be grounded but are not actually properly connected, or the conductive cloth's wires may have been removed but are still connected to the ground for other reasons (such as the conductive cloth directly touching the floor). This could result in a current loop being formed when a user uses a charging phone and the conductive cloth at the same time, causing the user to be shocked. Utility Model Content

[0005] In view of this, the creator has created a grounding detector to solve the above problems. It uses a first probe, a second probe, a current limiting component, and a light-emitting component to test whether the object being tested is grounded. The method of use is to insert the first probe into the socket hole, and then use the second probe to touch the object being tested. If the object being tested is grounded, a circuit loop will be formed, causing the light-emitting component to light up. The user can determine whether the object being tested is grounded by the light-emitting component, and at the same time, it can also determine whether the object being tested is conductive.

[0006] To achieve any of the above objectives, this utility model provides a grounding detector, comprising a first housing, a second housing, a wire, a current limiting component, and a light-emitting component. The first housing has a first probe extending from inside the first housing to outside. The second housing has a second probe extending from inside the second housing to outside. The wire connects the first housing and the second housing. The current limiting component is disposed inside the first housing and electrically connected to the first probe. The light-emitting component is disposed on the second housing and electrically connected to the second probe. The light-emitting component can be electrically connected to the current limiting component inside the first housing via the wire, allowing the light-emitting component to emit light according to the current flowing through the first probe and the second probe.

[0007] In one embodiment of the present invention, the first housing has a first end and a second end, which correspond to each other; the second housing has a third end and a fourth end, which correspond to each other; a first probe is located at the first end of the first housing; a second probe is located at the third end of the second housing; and a wire extends from the second end of the first housing and extends to the fourth end of the second housing.

[0008] In one embodiment of this utility model, the first end of the first housing has a first storage groove, and the third end of the second housing has a second storage groove. A first probe of the first housing can be inserted into the second storage groove of the second housing, and a second probe of the second housing can be inserted into the first storage groove of the first housing. The first housing and the second housing can be combined by inserting the first probe of the first housing into the second storage groove of the second housing, and inserting the second probe into the first storage groove of the first housing. Furthermore, the wire can be wound around the combined first and second housings to store the wire.

[0009] In one embodiment of this utility model, the grounding detector further includes a first fixing base, a second fixing base, and a sheath. The first fixing base is disposed at the second end of the first housing and located at the connection between the wire and the first housing. The second fixing base is disposed at the fourth end of the second housing and located at the connection between the wire and the second housing. The sheath is connected to the first fixing base and the second fixing base and is sleeved on the wire exposed outside the first housing and the second housing, so that the first fixing base, the second fixing base, and the sheath protect the wire and reduce the occurrence of wire breakage due to pulling.

[0010] In one embodiment of this utility model, the grounding detector further includes a first protrusion and a second protrusion. The first protrusion is disposed at the second end of the first housing, and a first receiving space is formed between the first protrusion and the first fixing base. The second protrusion is disposed at the fourth end of the second housing, and a second receiving space is formed between the second protrusion and the second fixing base. When the grounding detector is in its retracted state, the first and second receiving spaces are used to make the wires wound around the first and second housings more secure.

[0011] In one embodiment of this utility model, in the stored state, the first shell and the second shell together form an H shape for the wire to be wound.

[0012] In one embodiment of this utility model, the current limiting component is a current limiting resistor, and the light-emitting component is a neon lamp. When the first probe is inserted into the socket hole of the socket, and the second probe touches the detection object, and the detection object is conductive and grounded, a current loop is formed between the first probe, the second probe and the wire. The current limiting component limits the current flowing through the light-emitting component, so as to avoid damage to the light-emitting component or the detection object due to excessive current when it is detected.

[0013] In summary, the grounding detector of this utility model works by inserting the first probe of the first housing into the socket hole to contact the live wire, and then touching the detection object with the second probe of the second housing. By observing whether the light-emitting component on the second housing emits light, it is possible to determine whether the detection object is a conductive item and whether the detection object has come into contact with the ground.

Detailed Implementation

[0026] Architecture description of grounding detector Please refer to Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the overall appearance of the grounding detector according to an embodiment of the present invention. Figure 2 This is an overall cross-sectional view of the grounding detector according to an embodiment of the present invention.

[0027] The grounding detector 100 of this utility model includes a first housing 1, a second housing 2, and a wire 3. The first housing 1 and the second housing 2 are independent housings, and are connected together by the wire 3. The first housing 1 has a first end 11 and a second end 12, which correspond to each other. The second housing 2 has a third end 21 and a fourth end 22, which correspond to each other.

[0028] A first probe 111 extends from the surface of the first end 11 of the first housing 1 and a first receiving groove 112 is formed therein; a second probe 211 extends from the surface of the third end 21 of the second housing 2 and a second receiving groove 212 is formed therein; and as shown... Figure 2 As shown, the positions of the first probe 111 of the first housing 1 and the second probe 211 of the second housing 2, as well as the positions of the first storage groove 112 on the first housing 1 and the second storage groove 212 on the second housing 2, are offset from each other.

[0029] Inside the first housing 1 is a current limiting component 4, which is electrically connected to the first probe 111. The surface of the fourth end 22 of the second housing 2 is provided with a light-emitting component 5. The leads of the light-emitting component 5 extend into the interior of the second housing 2 and are electrically connected to the second probe 211. The light-emitting component 5 is then electrically connected to the current limiting component 4 inside the first housing 1 via a wire 3. Figure 2 As shown, in one embodiment of this utility model, the current limiting component 4 inside the first housing 1 can be a single current limiting resistor, and the light-emitting component 5 is also a neon lamp.

[0030] Please refer to the following: Figure 3 , Figure 4 , Figure 5 , Figure 3 This is a schematic diagram of the combination of the first housing and the second housing of the grounding detector according to an embodiment of the present invention. Figure 4 This is a cross-sectional view of the first housing and the second housing assembly of the grounding detector according to an embodiment of the present invention, and Figure 5 This is a schematic diagram showing the wires of the grounding detector of this embodiment wound around the first and second housings. Figure 4As shown, the first probe 111 of the first housing 1 corresponds to the second storage groove 212 on the second housing 2, and the second probe 211 of the second housing 2 also corresponds to the first storage groove 112 on the first housing 1. Furthermore, the shape of the first end 11 of the first housing 1 corresponds to the shape of the third end 21 of the second housing 2. Then, as... Figure 5 As shown, the first housing 1 can be connected to the second receiving groove 212 on the second housing 2 by inserting the first probe 111 into the second receiving groove 212 on the second housing 2, and the second housing 2 can be connected to the first end 11 of the first housing 1 and the third end 21 of the second housing 2 by inserting the second probe 211 into the first housing 1.

[0031] Then refer to Figures 3 to 5 The wire 3 connecting the first housing 1 and the second housing 2 extends from the second end 12 of the first housing 1 and then to the fourth end 22 of the second housing 2. There is a first fixing seat 31 at the connection between the wire 3 and the second end 12 of the first housing 1, and a second fixing seat 32 at the connection between the wire 3 and the second housing 2. The wire 3 exposed outside the first housing 1 and the second housing 2 is covered with a sheath 33 to prevent the grounding detector 100 from pulling the wire 3 too hard during use, causing the wire 3 to be broken or pulled away from the first housing 1 or the second housing 2.

[0032] Furthermore, when the first housing 1 and the second housing 2 are combined together, the wires 3 located outside the first housing 1 and the second housing 2 can be wound around the first housing 1 and the second housing 2 to store the wires 3, making the overall size of the grounding detector 100 smaller when stored. In addition, the second end 12 of the first housing 1 also has a first protrusion 121, and the first protrusion 121 forms a first receiving space S1 with the first fixing base 31. The fourth end 22 of the second housing 2 also has a second protrusion 221, and the second protrusion 221 forms a second receiving space S2 with the second fixing base 32. This makes the overall grounding detector 100 present an H-shape when stored, and allows the wires 3 to be wound around the first receiving space S1 and the second receiving space S2, so that the wires 3 can be more securely stored on the first housing 1 and the second housing 2.

[0033] Next, please refer to Figure 10 , Figure 11 , Figure 10 This is a schematic diagram of the overall appearance of the grounding detector according to the second embodiment of this utility model. Figure 11 This is an overall cross-sectional view of the grounding detector according to the second embodiment of this utility model. Figure 10 , Figure 11 In the embodiment, the ground detector 100' and the above-mentioned Figures 1 to 5The difference between the grounding detector 100 and the first housing 1 is that the first housing 1 does not have the first storage groove 112 and the first protrusion 121, and the second housing 2 does not have the second storage groove 212 and the second protrusion 221. The light-emitting component 5 is disposed on the side of the second housing 2, and the side of the second housing 2 is adjacent to the third end 21 and the fourth end 22 of the second housing 2.

[0034] Instructions for use of grounding detector Then refer to Figures 6 to 9 , Figure 6 This is a schematic diagram illustrating the use of a grounding detector to test the potential of a socket's holes according to an embodiment of this utility model. Figure 7 This is a schematic diagram illustrating the first embodiment of the present invention, showing how a grounding detector is used to test the grounding status of a test object. Figure 8 This is a schematic diagram illustrating the second embodiment of the present invention, showing how a grounding detector is used to test the grounding status of a test object. Figure 9 This is a block diagram illustrating the process of testing the potential of a socket's holes using a grounding detector, as described in an embodiment of this utility model.

[0035] Firstly, as Figure 6 and Figure 9 As shown, before using the grounding detector 100, the live wire socket of the socket SO must be confirmed. Step S01: Insert the first probe 111 of the first housing 1 into one of the sockets on the socket SO. Next, in step S02, touch the second probe 211 of the second housing 2 to any conductive first detection object T1 (such as an aluminum window) that is in contact with the ground, or directly to the ground. In step S03, if the light-emitting component 5 on the second housing 2 does not emit light, it indicates that this socket is the neutral wire. Then proceed to step S04, insert the first probe 111 of the first housing 1 into the other socket on the socket SO, and return to step S03. If the light-emitting component 5 on the second housing 2 emits light, it indicates that this socket is the live wire. After confirming that the socket is the live wire, proceed to step S05 to complete the pre-detection preparations.

[0036] Then as Figure 7 , Figure 8As shown, after the preparatory actions before testing are completed, the grounding detector 100 can be used to test whether the second test object T2 and the third test object T3 are conductive or whether they are in contact with the ground. In one embodiment of this utility model, the second test object T2 and the third test object T3 are the "Electrically Balanced Bedding" of Taiwan Patent No. M614030. The grounding detector 100 can be used to confirm whether this electrically balanced bedding is conductive and whether it is grounded. If the light-emitting component 5 emits light after testing, it indicates that the electrically balanced bedding is grounded and is indeed conductive. At this time, the user can use the electrically balanced bedding to discharge excess charge on the body to the ground. However, care should be taken not to use electrical products with plugged in to avoid electric shock.

[0037] Next, regarding the principle of the above detection method, when the first probe 111 of the first housing 1 touches the live wire, and the second probe 211 of the second housing 2 touches a conductive detection object that is in contact with the ground or directly touches the ground, a current loop can be formed between the live wire, the ground detector 100 and the ground. At this time, the current will flow to the first probe 111 of the first housing 1, through the current limiting component 4, then through the light-emitting component 5, and finally from the second probe 211 of the second housing 2 to the ground. The light-emitting component 5 is a neon lamp, and it can light up as long as the voltage supplied to the neon lamp reaches 90V or above. In addition, the current limiting component 4 is used to limit the current flowing through the neon lamp to prevent the neon lamp from being damaged due to excessive current.

[0038] In summary, the grounding detector of this invention works by inserting the first probe of the first housing into the socket to contact the live wire, and then touching the detection object with the second probe of the second housing. The detector can then determine whether the detection object is conductive and whether it is in contact with the ground by observing whether the light-emitting component on the second housing emits light. If the detection object is a bedding item with a balanced potential and is grounded, the user can use this bedding to discharge excess charge from their body to the ground. If the detection object is not grounded, the user does not need to worry about electric shock from using other plugged-in electrical appliances while using the bedding with a balanced potential.

[0039] The above-described figures and descriptions are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any other equivalent changes or modifications made by those skilled in the art based on the feature scope of the present utility model should be considered as not departing from the design scope of the present utility model.
