Description

Technical Field

[0001] This application relates to the field of electrical protection structure technology, specifically to an electricity meter. Background Technology

[0002] To prevent the meters from being opened at will, existing meters all use a lead-sealed structure. Specifically, the upper casing of the meter has screw holes and lugs with wire holes, and the base of the meter has a threaded post. The lead-sealed screw with a wire hole is passed through the screw hole of the upper casing and connected to the threaded post of the base to fix the upper casing and the base. Then, the lead-sealed wire is passed through the wire hole of the lug and the wire hole of the lead-sealed screw respectively. Finally, the two ends of the lead-sealed wire are sealed and fixed by the lead-sealed block.

[0003] Because these lead-sealing screws have through holes, their cost is relatively high. At the same time, the lead-sealing process is relatively complex and the lead-sealing efficiency is low. Therefore, this traditional lead-sealing structure of electricity meters has the following disadvantages: complex structure, high cost, and low production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an electricity meter that, while ensuring safety, solves the problems of complex structure, high cost, and low production efficiency of traditional lead seals.

[0005] To achieve the above objectives, this application provides an electricity meter, comprising:

[0006] The meter body, connector, and protective cover;

[0007] The main body of the electricity meter has a connection port;

[0008] The connector includes a wire and a connection end connected to one end of the wire. The connection end can be connected to the connection port, so that the connector is electrically connected to the meter body.

[0009] The protective cover can be fixedly installed on the meter body, including the port connection position of the connection end and the connection port, to isolate the port connection position from the outside. The other end of the wire can extend from the protective cover toward the outside of the meter body.

[0010] In an optional embodiment, the protective cover includes a first sidewall, a second sidewall, a third sidewall, a fourth sidewall, and a fifth sidewall connected in sequence. The first sidewall is disposed opposite to the third sidewall, and the second sidewall is disposed opposite to the fourth sidewall. The fourth sidewall is provided with a first snap-fit ​​member along the covering direction of the protective cover. The fourth sidewall and the fifth sidewall cooperate to form a clearance groove along the covering direction of the protective cover. The clearance groove is used for the wire to pass through.

[0011] The meter body is provided with a second snap-fit ​​component, and the first snap-fit ​​component and the second snap-fit ​​component can be snapped together to achieve the snap-fit ​​between the protective cover and the meter body.

[0018] In an optional embodiment,

[0019] The protrusion has a first extension in the direction away from the seventh sidewall, and the first extension is in the shape of a right triangular prism; the snap-fit ​​hole is a rectangular through hole and engages with the right triangular prism-shaped first extension.

[0020] The first extension can be inserted into the snap-fit ​​hole, and when the first extension is inserted into the snap-fit ​​hole, the protrusion engages with the snap-fit ​​hole.

[0021] In an optional embodiment,

[0022] The first snap-fit ​​member has a guide post on the fourth side wall along the covering direction of the protective cover, and the second snap-fit ​​member has a positioning hole on the seventh side wall.

[0023] During the assembly of the protective cover and the meter body, the guide post can be inserted into the positioning hole along the covering direction of the protective cover to guide the protrusion into the snap-fit ​​hole.

[0024] In an optional embodiment,

[0025] The connection end is provided with a connection end buckle, and the connector is connected to the connection port through the connection end buckle;

[0026] The connecting end latch includes a front end and a rear end.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which the embodiments of this application pertain. In the description of the embodiments of this invention, orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0059] Provide an electricity meter, such as Figure 1 , Figure 2 As shown, the electricity meter includes, but is not limited to, the meter body 20, a connector, and a protective cover 22. The meter body 20 may contain functional devices such as a control circuit board and a converter; the detailed structural features of this part are understood by those skilled in the art and will not be described further here. The meter body 20 has a connection port 200. The connector includes a wire 21 and a connection end 210 connected to one end of the wire 21. The connection end 210 can connect to the connection port 200, allowing the connector to be electrically connected to the meter body 20. The protective cover 22 can be fixedly installed on the meter body 20 and covers the connection position between the connection end 210 and the connection port 200. The other end of the wire 21 can extend from the protective cover 22 towards the outside of the meter body 20. This isolates the connection position from the outside environment, preventing the danger of accidental contact. The installation method involves first connecting the connector end 210 to the meter body 20, and then installing the protective cover 22 onto the meter body 20. This securely connects the protective cover 22 and the meter body 20, preventing the protective cover 22 from being opened arbitrarily. The protective cover 22 covers the port connection position between the connector and the meter body 20. The meter's structural design uses the protective cover 22 to shield the port connection position, preventing the connector from being pulled out by hand. The resulting seal also prevents electric shock, while ensuring that the connector wires 21 can pass through the protective cover 22 normally. This design ensures both usability and user experience, and features fewer parts, lower cost, and simple operation. The fact that the protective cover 22 is securely installed on the meter body 20 indicates that the connection is stable and cannot be easily opened manually.

[0060] In this embodiment, as Figure 1 , Figure 3As shown, the protective cover 22 includes a first sidewall 2241, a second sidewall 2242, a third sidewall 2243, a fourth sidewall 2244, and a fifth sidewall 2245 connected in sequence. The first sidewall 2241 and the third sidewall 2242 are arranged opposite to each other, and the second sidewall 2242 and the fourth sidewall 2244 are arranged opposite to each other. The fourth sidewall 2244 is provided with a first snap-fit ​​member 220 along the covering direction (Z direction) of the protective cover 22. The fourth sidewall 2244 and the fifth sidewall 2245 cooperate to form a relief groove 2250 along the covering direction of the protective cover 22. When the protective cover 22 is installed on the meter body 20, the fourth sidewall 2244 contacts the meter body 20, and the relief groove 2250 is used to pass through the wire 21 and thus protrude outward. The protective cover 22 can cover the port connection position between the connector and the meter body 20. The meter body 20 includes a sixth side wall 2041 and a seventh side wall 2042. Optionally, in this embodiment, the sixth side wall 2041 and the seventh side wall 2042 can be interconnected and vertically arranged. A second snap-fit ​​member 201 is provided on the seventh side wall 2042, and the first snap-fit ​​member 220 and the second snap-fit ​​member 201 can snap together. When snapped together, the seventh side wall 2042 contacts the fourth side wall 2244. When the protective cover 22 is snapped together with the meter body 20 through the first snap-fit ​​member 220 and the second snap-fit ​​member 201, the fifth side wall 2245 and the sixth side wall 2041 are opposite each other, forming a cavity 2260 with the first side wall 2241, the second side wall 2242, the third side wall 2243, the fourth side wall 2244 and the seventh side wall 2042. The connecting end 210 is located in the cavity 2260. The protective cover 22 is installed on the meter body 20 by a snap-fit ​​mechanism, eliminating the need for welding and bolts, making it lightweight and safe. It also offers economic benefits due to low processing costs and low installation repair rates. In other embodiments, the protective cover 22 can be connected to the meter body 20 via a plug-in or interference fit, and is not limited to this. It should be noted that this embodiment is merely an illustrative representation of one protective cover structure. In other embodiments, the shape of the protective cover is not limited to this; it can be an irregular shape or a hemispherical structure, as long as it forms a structure that covers and shields the connection end 210. In another implementation, the wire 21 can extend outward from the small gap between the protective cover 22 and the meter body 20.

[0061] In this embodiment, please refer to the following: Figure 1 , Figure 3 as well as Figure 4The first snap-fit ​​member 220 has a snap-fit ​​hole 2200, and the second snap-fit ​​member 201 has a protrusion 2010. The protrusion 2010 corresponds to and matches the snap-fit ​​hole 2200 in position and size. When the protective cover 22 is installed onto the meter body 20, the snap-fit ​​hole 2200 passes through the protrusion 2010, and the protrusion 2010 is inserted into the snap-fit ​​hole 2200 to form a connection. This achieves the mutual cooperation between the snap-fit ​​hole 2200 and the protrusion 2010, thereby realizing the snap-fit ​​connection between the first snap-fit ​​member 220 and the second snap-fit ​​member 201. This snap-fit ​​connection structure of the protrusion 2010 and the snap-fit ​​hole 2200 can reduce the space occupied while ensuring the reliability of the connection.

[0062] Optionally, the protrusion 2010 may have a first extension 2011 in a direction away from the seventh sidewall 2042, such as... Figure 3 , Figure 5a and Figure 5b As shown, the first extension 2011 is in the shape of a right triangular prism. The first extension 2011 can be inserted into the snap-fit ​​hole 2200. After the first extension 2011 is inserted into the snap-fit ​​hole 2200, the protrusion 2010 snaps into the snap-fit ​​hole 2200. The protrusion 2010 in this example has a simple structure, is tightly and firmly snapped in place, and is not easy to loosen. Once installed, it is difficult to disassemble, ensuring the safety of the meter in actual use.

[0063] Optional, see reference Figure 3 , Figure 6 The snap-fit ​​hole 2200 can be a rectangular through hole, which cooperates with the first extension 2011 of the protrusion 2010 in the direction away from the seventh side wall 2042. When the first extension 2011 is in the shape of a right triangular prism, the protrusion 2010 can be inserted into the snap-fit ​​hole 2200 to achieve snap-fit. Through this cooperation between the snap-fit ​​hole 2200 and the protrusion 2010, the connection is more secure.

[0064] In other embodiments, the protrusion 2010 may also engage with the snap-fit ​​hole 2200 in a hook-shaped snap-fit, a buckle snap-fit, a press-fit snap-fit, or other snap-fit ​​methods, and is not limited to these.

[0065] In this embodiment, as Figure 1 , Figure 3 , Figure 4As shown, the first snap-fit ​​component 220 has a guide post 2201 on the fourth side wall 2244 along the covering direction (Z direction) of the protective cover 22, and the second snap-fit ​​component 201 has a positioning hole 2020 on the seventh side wall 2042. During the assembly of the protective cover 22 and the meter body 20, the guide post 2201 will first be inserted into the positioning hole 2020 along the covering direction (Z direction) of the protective cover 22. As the installation continues, the portion of the guide post 2201 inserted into the positioning hole 2020 increases, so as to guide the protrusion 2010 to also be inserted into the snap-fit ​​hole 2200. The design of the guide post 2201 and the positioning hole 2020 can provide a guiding function for the protrusion 2010 to be inserted into the snap-fit ​​hole 2200, which facilitates the connection between the first snap-fit ​​component 220 and the second snap-fit ​​component 201.

[0066] like Figure 6 , Figure 9 As shown, for example, the guide post 2201 is semi-cylindrical and is arranged adjacent to the snap-fit ​​hole 2200 on the fourth side wall 2244. This structure has certain spatial advantages. In other embodiments, the guide post 2201 can be cylindrical, triangular prism, or quadrangular prism. The number of guide posts 2201 can be one or more. The positioning hole 2020 corresponds to the position of the guide post 2201. During installation, the guide post 2201 can be inserted into the positioning hole 2020. In addition, the shape and size of the positioning hole 2020 also match the guide post 2201. For example, when the guide post 2201 is cylindrical, the shape of the positioning hole 2020 is a circular through hole, and the size allows the guide post 2201 to be inserted into the positioning hole 2020 more tightly.

[0067] In this embodiment, as Figure 7 , Figure 8 As shown, the connector end 210 is provided with a connector end latch 211. The connector is connected to the connector port 200 through the connector end latch 211, so that the connector is connected to the meter body 20. The connector end latch 211 includes a latch front end 2110 and a latch rear end 2111. The latch front end 2110 can be inserted into the connector port 200, and the latch rear end 2111 is exposed outside the connector port 200 when the connector end latch 211 is connected to the connector port 200. When it is necessary to disconnect the connector end 210 from the connector port 200, the latch rear end 2111 can be pressed. The latch front end 2110 will tilt in the opposite direction to the pressing direction, thereby releasing the latch engagement with the connector port 200, allowing the connector end latch 211 to be pulled out from the connector port 200.

[0068] This spring-loaded snap-fit ​​design features a simple structure, high reusability, and low cost. In other embodiments, the connecting end snap-fit ​​211 can also be connected by a non-elastic method such as a pin-type snap-fit, and is not limited thereto.

[0069] In this embodiment, as Figure 1 , Figure 3 , Figure 4 As shown, the first snap-fit ​​member 220 has a first snap-fit ​​hole 2210 and a second snap-fit ​​hole 2220 formed on the fourth side wall 2244 along the covering direction (Z direction) of the protective cover 22. The second snap-fit ​​member 201 has a first protrusion 2012 and a second protrusion 2013 provided on the seventh side wall 2042. The first protrusion 2012 corresponds to the first snap-fit ​​hole 2210 in position and matches the size. When the protective cover 22 is installed on the meter body 20, the first snap-fit ​​hole 2210 can pass through the first protrusion 2012, and the first protrusion 2012 is inserted into the first snap-fit ​​hole 2210 for snap-fit, so as to realize the mutual cooperation between the first snap-fit ​​hole 2210 and the first protrusion 2012. Similarly, the second protrusion 2013 and the second snap-fit ​​hole 2220 are positioned and matched in size, so that when the protective cover 22 is installed onto the meter body 20, the second snap-fit ​​hole 2220 can also pass through the second protrusion 2013, allowing the second protrusion 2013 to be inserted into the second snap-fit ​​hole 2220 for snap-fit. Through the mutual cooperation of the first snap-fit ​​hole 2210 and the first protrusion 2012, and the second snap-fit ​​hole 2220 and the second protrusion 2013, the first snap-fit ​​member 220 and the second snap-fit ​​member 201 are connected in a snap-fit ​​manner. In other embodiments, the number of snap-fit ​​holes 2200 and protrusions 2010 can be two or more, further enhancing the stability of the connection.

[0070] In the above embodiments, such as Figure 3 , Figure 4 As shown, the protective cover 22 can be provided with fixing posts 223 on the second side wall 2242 along the covering direction (Z direction) of the protective cover 22. The meter body 20 is provided with a fixing ring 203 on the sixth side wall 2041. The fixing posts 223 and the fixing ring 203 are corresponding in position and matched in size, and cooperate with each other. During the assembly of the protective cover 22 and the meter body 20, the fixing posts 223 will be inserted into the fixing ring 203 along the covering direction (Z direction) of the protective cover 22, so that the protective cover 22 cannot be opened when subjected to a pulling force perpendicular to the fifth side wall 2245 (X direction). This is used to strengthen the connection between the protective cover 22 and the meter body 20 and prevent the protective cover 22 from shaking during installation and use.

[0071] For example, the fixing post 223 is a cuboid and the fixing ring 203 is a rectangle. In other embodiments, the fixing ring 203 can also be circular and the fixing post 223 can be a cylinder. The two cooperate with each other. In terms of connection method, the connection between the fixing post 223 and the fixing ring 203 can also be a snap-fit ​​or plug-in design, and is not limited to this.

[0072] Optional, such as Figure 3 , Figure 4 , Figure 9 As shown, the protective cover 22 may be provided with a first fixing post 2231 and a second fixing post 2232, and the meter body 20 is provided with a first fixing ring 2031 and a second fixing ring 2032. The first fixing ring 2031 is rectangular, and the first fixing post 2231 corresponds to the first fixing ring 2031 in position and matches in size, and they cooperate with each other. The second fixing ring 2032 is rectangular, and the second fixing post 2232 corresponds to the second fixing ring 2032 in position and matches in size, and they cooperate with each other. The protective cover 22 and the meter body... During assembly, along the direction of the protective cover 22 (Z direction), the first fixing post 2231 is inserted into the first fixing ring 2031, and the second fixing post 2232 is inserted into the second fixing ring 2032. This prevents the protective cover 22 from being opened under tension perpendicular to the fifth side wall 2245 (X direction), ensuring a stable connection between the protective cover 22 and the meter body 20. This further reduces shaking during installation and use, and strengthens the connection between the protective cover 22 and the meter body 20. Similarly, the connection between the first fixing post 2231 and the first fixing ring 2031, and between the second fixing post 2232 and the second fixing ring 2032, can also be a snap-fit ​​or plug-in design, and is not limited to this.
