Description

Technical Field

[0001] This application relates to the technical field of electricity meters, and in particular to an electricity meter with an RJ interface. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. It is mainly used to record the electrical energy consumed in a circuit, helping users to understand their electricity usage. It is widely used in homes, industries, and businesses.

[0003] In related technologies, an electricity meter includes a housing, a cover plate mounted on the housing, a mounting base inside the housing, and an RJ interface mounted on the mounting base. The RJ interface is used to connect a network cable to transmit the electrical energy data detected by the electricity meter to the network, allowing users to know their electricity consumption status, and plays a crucial role in the electricity meter.

[0004] However, the RJ interface of the aforementioned electricity meter is generally fixed to the mounting base with bolts. During installation, additional bolts, nuts, and other parts are required, which increases the assembly steps and makes it highly dependent on tools. Therefore, it needs to be improved. Utility Model Content

[0005] To simplify the assembly process of the RJ interface, this application provides an energy meter with an RJ interface.

[0006] The energy meter with an RJ interface provided in this application adopts the following technical solution:

[0007] An energy meter with an RJ interface includes a housing, a cover plate disposed on the housing, a mounting base disposed inside the housing, and an RJ interface disposed on the mounting base, wherein the RJ interface is interference-fitted with the mounting base.

[0008] By adopting the above technical solution, when connecting the RJ connector to the mounting base, simply open the cover plate first, then place the RJ connector into the mounting base, ensuring an interference fit between the RJ connector and the mounting base. Compared to connecting the RJ connector to the mounting base with bolts, this eliminates the need for additional bolts, nuts, and other parts, simplifying the assembly process of the RJ connector.

[0009] Optionally, the RJ interface is provided with a limiting block, and the mounting base is provided with an interconnected mounting groove and a limiting groove. The mounting groove is used for the RJ interface to extend into, and the limiting groove is used for the limiting block to extend into.

[0010] By adopting the above technical solution, when the RJ interface is inserted into the mounting slot, the limiting block will extend into the limiting slot, which facilitates the positioning of the RJ interface. At the same time, it increases the contact area between the RJ interface and the mounting base, making the connection between the RJ interface and the mounting base more secure.

[0011] Optionally, the limiting block and the limiting groove are interference-fitted.

[0012] By adopting the above technical solution, when the RJ interface is inserted into the mounting slot, the limiting block will extend into the limiting slot. The limiting block can prevent the RJ interface from moving in a direction perpendicular to the direction in which the RJ interface is inserted into the mounting slot, so that the connection between the RJ interface and the mounting base is highly stable.

[0013] Optionally, the mounting base has a fastening groove communicating with the mounting slot, and a fastening block is provided in the fastening groove. The fastening block is interference-fitted with the fastening groove. The fastening block includes a dovetail and a connecting part fixedly connected to the dovetail. The connecting part is close to the side wall of the RJ interface, and the width of the dovetail on the side away from the connecting part is greater than the width on the side close to the connecting part.

[0014] By adopting the above technical solution, after the RJ interface is inserted into the mounting groove, the fastening block is then inserted into the fastening groove, resulting in an interference fit between the fastening block and the fastening groove. The fastening block can limit the movement of the limiting block, making it difficult for the limiting block to move in a direction perpendicular to the direction in which the RJ interface is inserted into the mounting groove. The connecting part can press the RJ interface against the groove wall of the mounting groove, thereby fixing the RJ interface and further enhancing the connection strength between the RJ interface and the mounting base.

[0015] Optionally, in the direction along which the RJ interface extends into the mounting groove, the depth of the fastening groove is greater than the depth of the limiting groove.

[0016] By adopting the above technical solution, when the fastening block is inserted into the fastening groove, the contact area between the fastening block and the groove wall increases, thereby making the interference fit between the fastening block and the fastening groove more secure, and the fastening block has a good limiting effect on the limiting block and the limiting effect on the RJ interface.

[0017] Optionally, the dovetail portion is provided in two parts and is located on both sides of the connecting portion.

[0018] By adopting the above technical solution, when the fastening block is placed in the fastening groove, the dovetails at both ends can prevent the fastening block from moving towards the mounting groove, while increasing the contact area between the fastening block and the groove wall, thus making the connection strength between the fastening block and the groove wall high.

[0019] Optionally, the extending direction of the fastening groove is parallel to the extending direction of the mounting groove.

[0020] By adopting the above technical solution, when the fastening block is inserted into the fastening groove, the side wall of the fastening block will contact the side wall of the RJ interface, thereby further pressing the RJ interface into the mounting groove, thus achieving a better limiting effect on the RJ interface in the direction perpendicular to the RJ interface extending into the mounting groove.

[0021] Optionally, the extending direction of the fastening groove is perpendicular to the extending direction of the mounting groove.

[0022] By adopting the above technical solution, when the fastening block is inserted into the fastening groove, the dovetails at both ends can prevent the fastening block from moving out of the mounting groove towards the RJ interface. Furthermore, since the connecting part is in close contact with the RJ interface, it can also prevent the RJ interface from moving out of the mounting groove, thus improving the limiting effect on the RJ interface in the direction along which the RJ interface extends into the mounting groove.

[0023] Optionally, the cover plate has a fixed cover on the side near the RJ interface, and when the cover plate is connected to the housing, the fixed cover abuts against the RJ interface.

[0024] By adopting the above technical solution, after the cover plate is closed, the fixing cover will abut against the RJ interface, making it difficult for the RJ interface to come out of the mounting slot, and providing a good limiting effect for the RJ interface.

[0025] Optionally, the fastening block is provided with a cover, which is located on the side of the RJ interface near the cover plate.

[0026] By adopting the above technical solution, when the fastening block is set in the fastening groove, the cover is fixed on the side of the RJ interface near the cover plate. The cover can prevent the RJ interface from moving to the side near the cover plate, thereby limiting the RJ interface.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The RJ interface is fixed to the mounting base by interference fit between the RJ interface and the mounting slot, without the need for additional bolts, nuts and other parts, which simplifies the assembly steps of the RJ interface;

[0029] 2. When assembling the RJ interface, first use the limiting block to limit the RJ interface, and then use the fastening block to press the RJ interface into the mounting groove. This ensures that the limiting block and the fastening block have a good fixing effect on the RJ interface, making installation easier. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses an energy meter with an RJ interface.

[0042] Example 1

[0043] Reference Figure 1 and Figure 2 An energy meter with an RJ interface includes a housing 1, a cover plate 11 disposed on the housing 1, a mounting base 12 disposed inside the housing 1, an RJ interface 13 disposed on the mounting base 12, and a limiting block 2 disposed on the RJ interface 13. In this embodiment, the cover plate 11 is rotatably connected to the housing 1. The mounting base 12 has a mounting groove 4 for the RJ interface 13 to extend into, and a limiting groove 5 communicating with the mounting groove 4. The RJ interface 13 is interference-fitted with the mounting groove 4, and the limiting block 2 is disposed in the limiting groove 5.

[0044] Reference Figure 2 and Figure 3 When the RJ interface 13 extends into the mounting slot 4, the limiting block 2 extends into the limiting slot 5 and is interference-fitted with the limiting slot 5. The limiting block 2 can prevent the RJ interface 13 from moving in a direction perpendicular to the direction in which the RJ interface 13 extends into the mounting slot 4, thereby fixing the RJ interface 13 on the mounting base 12. A fixing cover 71 is provided on the side of the cover plate 11 near the RJ interface 13. The fixing cover 71 is composed of three plates provided on the cover plate 11. When the cover plate 11 is closed, the fixing cover 71 can either abut against the RJ interface 13 or cover the RJ interface 13, thereby preventing the RJ interface 13 from moving out of the mounting slot 4.

[0045] The implementation principle of an energy meter with an RJ interface according to an embodiment of this application is as follows: When it is necessary to fix the RJ interface 13 to the mounting base 12, simply insert the RJ interface 13 into the mounting groove 4 so that the limiting block 2 is located in the limiting groove 5. By assembling the RJ interface 13 in the above manner, no additional screws or nuts are required, simplifying the assembly steps and making the operation convenient.

[0046] Example 2

[0047] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the mounting base 12 is further provided with a fastening groove 6 that communicates with the mounting groove 4. The fastening groove 6 communicates with the limiting groove 5. In the direction that extends into the mounting groove 4 along the RJ interface 13, the depth of the fastening groove 6 is greater than the depth of the limiting groove 5. A fastening block 3 is provided in the fastening groove 6, and the fastening block 3 is interference-fitted with the fastening groove 6.

[0048] Reference Figure 4 and Figure 5 The fastening block 3 includes a dovetail portion 31 and a connecting portion 32 connected to the dovetail portion 31. The connecting portion 32 is in close contact with the side wall of the RJ interface 13, so that the fastening block 3 can press the RJ interface 13 against the wall of the mounting groove 4. The width of the side of the dovetail portion 31 away from the connecting portion 32 is greater than the width of the side closer to the connecting portion 32. In this embodiment, the cross-section of the dovetail portion 31 is preferably trapezoidal, and the width of the dovetail portion 31 gradually decreases from the end away from the connecting portion 32 to the end closer to the connecting portion 32. In other embodiments, it can also be changed to a T-shaped structure or other structures that can limit the position of the fastening block.

[0049] The implementation principle of an energy meter with an RJ interface according to an embodiment of this application is as follows: When the RJ interface 13 needs to be connected to the mounting base 12, simply insert the RJ interface 13 into the mounting groove 4 so that the limiting block is located in the limiting groove 5, and then insert the fastening block 3 into the fastening groove 6 so that the fastening block 3 and the fastening groove 6 are interference-fitted. Fixing the RJ interface 13 in the above manner further enhances the limiting effect on the RJ interface 13.

[0050] Example 3

[0051] Reference Figure 6 The difference between this embodiment and embodiment 2 is that: two dovetail portions 31 are provided and connected to both sides of the connecting portion 32. The length of the connecting portion 32 in this embodiment is greater than the length of the connecting portion 32 in embodiment 2. The extending direction of the fastening groove 6 is parallel to the extending direction of the mounting groove 4, and the direction in which the fastening block 3 extends into the fastening groove 6 is consistent with the direction in which the RJ interface 13 extends into the mounting groove 4. The limiting effect on the RJ interface 13 is good in the direction perpendicular to the direction in which the RJ interface 13 extends into the mounting groove 4.

[0052] The implementation principle of an energy meter with an RJ interface in this application embodiment is as follows: when the fastening block 3 is inserted into the fastening groove 6, the dovetails 31 at both ends of the connecting part 32 can limit the fastening block 3, making it difficult for the fastening block 3 to move towards the mounting groove 4, thereby making the connection structure have a good fixing effect on the RJ interface 13.

[0053] Example 4

[0054] Reference Figure 7 The difference between this embodiment and embodiment 3 is that the direction in which the fastening block 3 extends into the fastening groove 6 is perpendicular to the direction in which the RJ interface 13 extends into the mounting groove 4, and the extension direction of the fastening groove 6 is perpendicular to the extension direction of the mounting groove 4. Furthermore, the fastening block 3 is located directly above the RJ interface 13, which provides a good limiting effect on the RJ interface 13 in the direction parallel to the direction in which the RJ interface 13 extends into the mounting groove 4.

[0055] The implementation principle of an energy meter with an RJ interface in this application embodiment is as follows: when the fastening block 3 extends into the fastening groove 6, the dovetail 31 can prevent the fastening block 3 from moving out of the fastening groove 6 in the direction of the RJ interface 13 extending out of the mounting groove 4. The contact area between the fastening block 3 and the groove wall of the fastening groove 6 is increased, which makes the connection stability between the fastening block 3 and the groove wall of the fastening groove 6 high, thereby making the connection structure have a good fixing effect on the RJ interface 13.

[0056] Example 5

[0057] Reference Figure 8 The difference between this embodiment and embodiment 2 is that: two fastening blocks 3 are provided and are respectively located on both sides of the RJ interface 13. The mounting base 12 has two fastening grooves 6 that communicate with the mounting groove 4, and one of the fastening grooves 6 communicates with the limiting groove 5. Each fastening block 3 is interference-fitted with the corresponding fastening groove 6. A cover 72 is fixed on both fastening blocks 3. The cover 72 is located on the side of the RJ interface 13 near the cover plate 11.

[0058] The implementation principle of an energy meter with an RJ interface in this application embodiment is as follows: When it is necessary to install the RJ interface 13, simply insert the RJ interface 13 into the mounting groove 4 so that the limiting block 2 is located in the limiting groove 5, and then insert both fastening blocks 3 into the fastening groove 6. At this time, the cover 72 is located on the side of the RJ interface 13 near the cover plate 11, which can prevent the RJ interface 13 from moving out of the mounting groove 4.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
