Description

Technical Field

[0001] This utility model belongs to the field of electricity meter accessories, specifically relating to an electricity meter connector. Background Technology

[0002] As the core equipment for electricity metering, electricity meters are widely used in industrial, commercial, and residential electricity consumption. With the construction of smart grids and the increasing demands of users, electricity meters need to be regularly inspected, replaced, or upgraded. Traditional electricity meter replacement operations usually involve power outages, requiring the power supply to the user's side or the line side to be disconnected before the old meter can be removed and the new meter installed. This power outage operation brings many problems: power outages can disrupt users' production, daily life, or the operation of important equipment, causing economic losses or inconvenience, especially in places with high requirements for power supply continuity, such as hospitals, data centers, and continuous production enterprises. Moreover, in some cases, the power outage and restoration procedures are cumbersome, requiring power workers to strictly follow safety procedures, increasing operation time and manpower input. Existing uninterrupted meter replacement solutions on the market require the use of additional shorting devices. During meter replacement, the shorting device is held and attached to the electricity meter connector to short-circuit the circuit. After the meter replacement is completed, the shorting device is manually pulled out. This operation method is cumbersome, and in practical applications, there is also the problem of the shorting device being lost. Utility Model Content

[0003] In response to this, the present invention provides an easy-to-use electricity meter connector that enables the replacement of electricity meters without interrupting power, thereby avoiding the problem of needing to disconnect power when replacing electricity meters.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides an electricity meter connector, including a meter base, a terminal block, wiring terminals, plug-in terminals, and a flip-top. The terminal block is fixed on the meter base, the wiring terminals are mounted on the terminal block, and the flip-top is rotatable between a first position and a second position relative to the meter base. The plug-in terminals are fixed on the flip-top and correspondingly arranged with respect to the wiring terminals. The plug-in terminals have a plug section suitable for connection with an electricity meter. A resilient shorting element is mounted on the terminal block. In the first position, the plug-in terminals are connected to the corresponding wiring terminals, and the flip-top applies pressure to the resilient shorting element to separate it from the wiring terminals. In the second position, the plug-in terminals are separated from the corresponding wiring terminals, and the resilient shorting element contacts the two wiring terminals under elastic force.

[0006] Preferably, the elastic shorting element includes a shorting conductor and a spring. The shorting conductor is movably mounted on the terminal block for connecting and disconnecting two terminals, and the spring provides elastic force to the shorting conductor.

[0007] Preferably, the terminal block is provided with a mounting part for mounting a shorting conductor and a spring. The mounting part is provided with a limiting groove for limiting the movement of the shorting conductor. One end of the spring abuts against the shorting conductor, and the other end abuts against the mounting part.

[0008] Preferably, the flip seat is connected to the terminal seat or the meter seat via a pivoting structure; the pivoting structure includes a cooperating pivot shaft and a pivot hole, one of which is located on the flip seat and the other on the terminal seat or the meter seat.

[0009] Preferably, one of the wiring terminal and the meter terminal is provided with a connector, and the other is provided with a resilient locking head. When the flip seat is in the first position, the connector is engaged with the resilient locking head.

[0010] Preferably, the connector is a cylindrical structure, the elastic clamp has a tubular cavity for accommodating the connector, and the tubular cavity has an opening for the connector to extend into. The sidewall of the tubular cavity is provided with an axially extending slot to divide the tubular cavity into a plurality of radially elastically deformable clamping arms.

[0011] Preferably, the flip-top has a pressing part between two adjacent terminals. When the flip-top is in the first position, the pressing part abuts against the elastic shorting member to separate the elastic shorting member from the terminal.

[0012] Preferably, a snap-fit ​​structure is provided between the watch base and the flip base, and the flip base is engaged with the watch base through the snap-fit ​​structure when it is in the first position.

[0013] Preferably, the base is provided with a snap-fit ​​groove, and the terminal block snaps into the snap-fit ​​groove.

[0014] Preferably, the terminal block is provided with a mounting hole, and the wiring terminal is installed in the mounting hole; the wiring terminal is provided with a wiring hole, the side wall of the wiring hole is provided with a screw hole, and the side wall of the mounting hole is provided with a screw through hole opposite to the screw hole, and the wire screw passes through the screw through hole to form a threaded engagement with the screw hole.

[0015] The positive effects of this utility model are as follows: The structure of the electricity meter connector in this utility model has been optimized. Through the linkage design of the flip base and the elastic shorting member, this structure realizes convenient operation of the electricity meter replacement process, and the entire operation does not require power interruption: When the flip base is in the first position (working position), the electricity meter is installed on the flip base (the connector remains connected to the electricity meter), the connector terminal is reliably connected to the wiring terminal for normal metering, and at the same time the flip base presses down the elastic shorting member to disengage it from the wiring terminal, ensuring accurate metering without bypass; When it is necessary to replace the meter, the flip base is flipped to the second position (meter replacement position). In this position, the electricity meter can be disassembled and installed. The connector terminal disengages from the wiring terminal to disconnect the electricity meter connection. At the same time, the elastic shorting member resets under the action of elastic force and reliably shorts the two wiring terminals, forming a current bypass channel to ensure continuous power supply to the line; After the meter replacement is completed, during the process of flipping the flip base from the second position to the first position, the connector terminal contacts the wiring terminal and pushes the elastic shorting member to separate from the wiring terminal, entering normal electricity metering. This process is driven entirely by the flipping action, requiring no additional operation or tools. It completely isolates the meter to be replaced while ensuring absolute continuity of power supply, significantly improving operational safety and work efficiency, and is highly practical.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] The structure of the electricity meter connector in this embodiment of the utility model is as follows: Figures 1 to 12As shown, it includes a meter base 1, a terminal block 2, a wiring terminal 3, a meter insertion terminal 4, and a flip base 5; wherein the wiring terminal 3 and the meter insertion terminal 4 are preferably made of copper; the terminal block 2 is fixed on the meter base 1, the wiring terminal 3 is mounted on the terminal block 2, and the flip base 5 can rotate relative to the meter base 1 between a first position (working position) and a second position (meter changing position). The angle of movement of the flip base 5 between the first position and the second position can be set as needed, such as setting the angle of movement to 40 degrees, 50 degrees, or 60 degrees, etc. When the flip base 5 is rotated to the second position, it can be stopped and limited by abutting against the terminal block 2; the meter insertion terminal 4 is fixed on the flip base 5 and... The wiring terminals 3 are correspondingly provided; the meter insertion terminal 4 has a plug section 41 suitable for connection with the electricity meter, the plug section 41 is used to insert into the conductive hole on the electricity meter when the electricity meter is installed, so as to realize the electrical connection between the meter insertion terminal 4 and the electricity meter; an elastic shorting member 6 is installed on the terminal base 2; when the flip base 5 is in the first position, the meter insertion terminal 4 is connected to the corresponding wiring terminal 3, and at the same time the flip base 5 applies pressure to the elastic shorting member 6 so as to separate the elastic shorting member 6 from the wiring terminal 3; when the flip base 5 is in the second position, the meter insertion terminal 4 is separated from the corresponding wiring terminal 3, and the elastic shorting member 6 contacts the two wiring terminals 3 under the action of elastic force to realize short connection.

[0033] The structure of this utility model, through the linkage design of the flip base 5 and the elastic shorting member 6, realizes convenient operation of the electricity meter replacement process, and the entire operation does not require power interruption: When the flip base 5 is in the first position (working position), the electricity meter is installed on the flip base 5 (the plug section 41 remains connected to the electricity meter), the plug terminal 4 is reliably connected to the wiring terminal 3 for normal electricity metering, and at the same time, the flip base 5 presses down the elastic shorting member 6 to disengage it from the wiring terminal 3, ensuring accurate metering without bypass; when the meter needs to be replaced, the flip base 5 is flipped to the second position (meter replacement position), in which the electricity meter can be disassembled and installed and replaced, the plug terminal 4 disengages from the wiring terminal 3 to disconnect the electricity meter, and at the same time, the elastic shorting member 6 reliably shorts the two wiring terminals 3 under the action of elasticity, forming a current bypass channel to ensure continuous power supply to the line; after the meter replacement is completed, during the process of flipping the flip base 5 from the second position to the first position, the plug terminal 4 contacts the wiring terminal 3 and pushes the elastic shorting member 6 to separate from the wiring terminal 3, entering normal electricity metering. This process is driven entirely by the flipping action, requiring no additional operation or tools. It completely isolates the meter to be replaced while ensuring absolute continuity of power supply, significantly improving operational safety and work efficiency; it is highly practical.

[0034] like Figure 7As shown, the elastic shorting component 6 includes a shorting conductor 61 and a spring 62. The shorting conductor 61 is movably mounted on the terminal block 2 to realize the connection and disconnection between the two terminals 3. The spring 62 provides elastic force to the shorting conductor 61. The spring 62 is preferably a helical compression spring, but in actual operation, the spring 62 can also be a spring sheet. When the flip seat 5 is in the first position (working position), the spring 62 is compressed, and the shorting conductor 61 does not contact the terminal 3. When the flip seat 5 is in the second position (changing position), the shorting conductor 61 contacts the terminal 3 under the elastic force of the spring 62, shorting the circuit.

[0035] Furthermore, the terminal block 2 is provided with a mounting part 20 for mounting the shorting conductor 61 and the spring 62. The mounting part 20 is provided with a limiting groove for limiting the movement of the shorting conductor 61. One end of the spring 62 abuts against the shorting conductor 61, and the other end abuts against the mounting part 20. The limiting groove can prevent the shorting conductor 61 from slipping.

[0036] See Figure 7 and Figure 12 As shown, in this embodiment, the flip seat 5 and the terminal seat 2 are connected by a pivot structure. The pivot structure includes a cooperating pivot shaft 23 and a pivot hole. A pivot hole 52 is provided on the flip seat 5, and a corresponding pivot shaft 23 is provided on the terminal seat 2. The flip seat 5 is rotatably connected to the terminal seat 2 by the pivot shaft 23 engaging with the pivot hole 52. In actual operation, a pivot hole can also be provided on the terminal seat 2, and a corresponding pivot shaft can be provided on the flip seat 5.

[0037] As a modified implementation, the pivot shaft 23 and the pivot hole 52 can also be arranged between the flip seat 5 and the dial base 1, that is, one of the mating pivot shaft 23 and the pivot hole 52 is arranged on the flip seat 5 and the other is arranged on the dial base, so that the flip seat 5 can also be rotatably installed.

[0038] See Figures 8 to 10 To achieve a quick and reliable connection between terminal 3 and meter terminal 4, a connector 7 is provided on terminal 3, and a resilient locking head 8 is provided on meter terminal 4. During the flipping process of the flipping seat 5 from the second position to the first position, the connector 7 gradually engages with the resilient locking head 3. When the flipping seat 5 flips to the first position, the connector 7 is fully engaged with the resilient locking head 8, and simultaneously, the resilient shorting member 6 separates from the terminal 3. As a modified implementation, in actual operation, the connector 7 can also be placed on meter terminal 4, and the resilient locking head 3 can be placed on terminal 3. The engaging and engaging relationship between the resilient locking head 8 and the connector 7 ensures a reliable connection between terminal 3 and meter terminal 4.

[0039] Continue reading Figure 3 and Figures 7 to 9 The connector 7 has a cylindrical structure, and the elastic clamp 8 has a tubular cavity to accommodate the connector 7. The tubular cavity has an opening 81 for the connector 7 to extend into. The sidewall of the tubular cavity has an axially extending slot 83 to divide the tubular cavity into several radially elastically deformable clamping arms 82. After the connector 7 extends into the tubular cavity, the inner surface of the clamping wall 82 adheres to the outer surface of the connector 7, thereby achieving a reliable electrical connection. Preferably, the connector 7 is a cylindrical structure, and the tubular cavity is a matching circular cavity.

[0040] See Figure 7 and Figure 12 The flip seat 5 has a pressing part 51 between two adjacent terminals 3. When the flip seat 5 is in the first position, the pressing part 51 abuts against the elastic shorting member 6 so that the elastic shorting member 6 is separated from the terminal 3. Preferably, the pressing part 51 can be integrally injection molded with the flip seat 5.

[0041] To ensure the stability of the flip seat 5 when it is flipped to the first position, a snap-fit ​​structure 9 is further provided between the watch base 1 and the flip seat 5. The snap-fit ​​structure 9 can be provided on the flip seat 5 or on the watch base 1. When the flip seat 5 is in the first position, it is engaged with the watch base 1 through the snap-fit ​​structure 9, thereby enhancing the positioning effect of the flip seat 5.

[0042] See Figure 11 As shown, a snap-fit ​​groove 11 is provided on the base 1, and the terminal block 2 is snapped into the snap-fit ​​groove 11 to enhance the fixing effect of the terminal block 2.

[0043] Preferably, the terminal block 2 is provided with a mounting hole 21, and the terminal block 3 is installed in the mounting hole 21; the terminal block 3 is provided with a wiring hole 31, and the side wall of the wiring hole 31 is provided with a screw hole, and the side wall of the mounting hole 21 is provided with a screw through hole 22 opposite to the screw hole. The wire clamping screw 32 passes through the screw through hole 22 and forms a threaded engagement with the screw hole. When wiring, the end of the wire is inserted into the wiring hole 31, and then the wire clamping screw 32 is tightened. The wire is clamped in the wiring hole 31 by the wire clamping screw 32, thereby ensuring a reliable connection between the wire and the terminal block 3.

[0044] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
