Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electricity meter accessories, and in particular, it relates to a protective cover structure for a smart electricity meter connector. Background Technology
[0002] An electricity meter is an instrument used to measure electrical energy. It is fixedly installed inside a meter box via connectors. A connector is an accessory made of plastic with embedded metal parts, which enables quick connection and disconnection of the electricity meter from other devices or lines. To cover and protect the interface of the electricity meter, a protective cover (top cover) is usually installed on the connector.
[0003] Most existing protective cover structures for smart meter connectors use plastic clips to directly attach the cover to the outside of the connector. However, when it is necessary to remove the protective cover to connect wires or install the meter, the cover must be snapped open. The plastic clips have poor durability and a short service life. Furthermore, repeated snapping and opening can cause the clips to loosen, directly affecting the protective effect of the cover. Therefore, there is an urgent need for a new protective cover structure for smart meter connectors to solve this problem. Utility Model Content
[0004] The purpose of this utility model is to provide a protective cover structure for a smart energy meter connector to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective cover structure for a smart energy meter connector, comprising a single-phase energy meter connector body, a mounting block for mounting the connector pins, and a protective cover for the connector. The protective cover has a horizontally opened mounting hole on its side wall, a rod is slidably installed in the mounting hole, a strip plate is fixedly installed on the side of the rod near the body, and a turntable is fixedly installed on the other end of the rod. The sidewall of the mounting block is provided with a circular groove corresponding to the strip plate. A strip plate is fixedly installed at the opening of the circular groove, and the strip holes on the strip plate match the strip plate. A rectangular groove is provided on one side of the mounting block, and a rectangular sealing ring is slidably installed inside the rectangular groove. A push spring is fixedly installed on the side wall of the rectangular sealing ring and one side of the inner wall of the rectangular groove.
[0006] Preferably, a spring is fixedly installed on the inner wall of the mounting hole, and the spring is slidably sleeved to the outer side of the insertion rod.
[0007] Preferably, a retaining ring is fixedly installed at the end of the spring, and the inner wall of the retaining ring is fixedly connected to the side wall of the insert rod.
[0008] Preferably, the protective cover has a rectangular snap-fit groove on its side wall, which matches the rectangular sealing ring.
[0009] Preferably, two limiting blocks are symmetrically fixedly installed on the outer wall of the rectangular sealing ring, and limiting grooves are symmetrically formed on the inner wall of the rectangular groove.
[0010] Preferably, the two limiting blocks fixedly installed on the outer wall of the rectangular sealing ring are slidably connected to the inside of the limiting groove opened on the inner wall of the rectangular groove.
[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The protective cover structure of this smart energy meter connector benefits from the installation holes, insert rod, strip plate, and circular groove on the side wall of the mounting block provided on the side wall of the protective cover. This allows the protective cover to be pressed against the side wall of the mounting plate, and then the insert rod to be pushed towards the mounting block. This causes the strip plate, which is fixedly installed at the end of the insert rod, to extend into the circular groove. Since a strip perforated plate is fixedly installed at the opening of the circular groove, when the strip plate extends into the circular groove and passes through the strip perforated plate, the insert rod is rotated to cause the strip plate to be misaligned with the strip perforated plate. This limits the position of the strip plate and the side wall of the protective cover, thus completing the installation of the protective cover. The protective cover structure of this smart energy meter connector benefits from the rectangular groove, rectangular sealing ring, and push spring on the side wall of the mounting block. When the protective cover abuts against the side wall of the mounting block and is installed, the rectangular sealing ring fixedly installed on the side wall of the mounting block is pressed into the rectangular groove, and the push spring is compressed. At the same time, the push spring pushes the rectangular sealing ring fixedly installed at its end to abut against the rectangular snap-fit groove opened on the side wall of the protective cover. This can effectively form a seal between the protective cover and the mounting block, thereby further improving the protective effect of the protective cover on the connector. Compared with existing technologies, the protective cover structure of this smart energy meter connector allows for easy disassembly and assembly of the protective cover, while further improving the protective effect of the connector.

[0015] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0016] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0018] like Figures 1 to 7 The protective cover structure of a smart energy meter connector shown is mainly composed of a single-phase energy meter connector body 1, a mounting block 2 for mounting the connector pins, and a protective cover 3 for the connector. The protective cover 3 has a horizontal mounting hole 4 on its side wall. A plug rod 5 is slidably installed in the mounting hole 4. A strip plate 6 is fixedly installed on the side of the plug rod 5 near the body 1. A turntable is fixedly installed on the other end of the plug rod 5. Both ends of the plug rod 5 extend to the two ends of the mounting hole 4, and the strip plate 6 and the turntable are fixedly installed on the two ends of the plug rod 5, and the strip plate 6 is the side that connects to the protective cover 3 and the mounting block 2. The side wall of mounting block 2 is provided with a circular groove 7 corresponding to the strip plate 6. A strip plate with a perforated hole is fixedly installed at the opening of the circular groove 7, and the strip holes on the perforated plate match the strip plate 6. Thanks to the setting of mounting hole 4, insert rod 5, strip plate 6 and circular groove 7 on the side wall of mounting block 2, the protective cover 3 can be abutted against the side wall of mounting block 2. Then, the insert rod 5 is pushed towards the mounting block 2, which can drive the strip plate 6 fixedly installed at the end of the insert rod 5 to extend into the circular groove 7. Since the strip plate with a perforated hole is fixedly installed at the opening of the circular groove 7, when the strip plate 6 extends into the circular groove 7 and passes through the strip plate with a perforated hole, the insert rod 5 is rotated to drive the strip plate 6 to be misaligned with the strip plate with a perforated hole. This can limit the strip plate 6 and limit the side wall of the protective cover 3, thus completing the installation of the protective cover 3. A rectangular groove 8 is provided on one side of the mounting block 2. A rectangular sealing ring 9 is slidably installed inside the rectangular groove 8. A push spring 10 is fixedly installed on the side wall of the rectangular sealing ring 9 and one side of the inner wall of the rectangular groove 8. Thanks to the rectangular groove 8, the rectangular sealing ring 9 and the push spring 10 on the side wall of the mounting block 2, when the protective cover 3 abuts against the side wall of the mounting block 2 and is installed, the rectangular sealing ring 9 fixedly installed on the side wall of the mounting block 2 is squeezed and moved into the rectangular groove 8. At the same time, the push spring 10 is compressed. Simultaneously, the push spring 10 pushes the rectangular sealing ring 9 fixedly installed at its end to abut against the rectangular snap-fit groove 13 opened on the side wall of the protective cover 3. This can effectively form a seal between the protective cover 3 and the mounting block 2, thereby further improving the protective effect of the protective cover 3 on the plug-in component.
[0019] A spring 11 is fixedly installed on the inner wall of the mounting hole 4, and the spring 11 is slidably sleeved to the outside of the insertion rod 5. A fixing ring 12 is fixedly installed at the end of the spring 11. The inner wall of the fixing ring 12 is fixedly connected to the side wall of the insertion rod 5. Thanks to the setting of the spring 11, when the insertion rod 5 is pushed to drive the strip plate 6 to be inserted into the circular groove 7 and rotated to lock in place, the spring 11 will push the insertion rod 5 to move towards the protective cover 3. At the same time, it will drive the strip plate 6 fixedly installed at its end to fit tightly against the side wall of the strip plate fixedly installed at the opening of the circular groove 7, thereby further improving the stability between the mounting block 2 and the protective cover 3.
[0020] The protective cover 3 has a rectangular snap-fit groove 13 on its side wall. The rectangular snap-fit groove 13 matches the rectangular sealing ring 9. Thanks to the setting of the rectangular snap-fit groove 13, the sealing effect between the rectangular sealing ring 9 and the protective cover 3 can be further improved by snapping the rectangular sealing ring 9 into the inside of the rectangular snap-fit groove 13.
[0021] Two limiting blocks 14 are symmetrically fixedly installed on the outer wall of the rectangular sealing ring 9. Limiting grooves are symmetrically opened on the inner wall of the rectangular groove 8. The two limiting blocks 14 fixedly installed on the outer wall of the rectangular sealing ring 9 are slidably connected to the inside of the limiting grooves opened on the inner wall of the rectangular groove 8. Thanks to the setting of the limiting blocks 14, the stability of the rectangular sealing ring 9 when sliding can be effectively improved, and the sliding direction of the rectangular sealing ring 9 can be limited.
[0022] Working principle The protective cover structure of this smart energy meter connector requires installation of the protective cover 3. First, align the protective cover 3 with the mounting block 2 and press it against the mounting block 2, simultaneously aligning the two strip plates 6 with the strip-shaped perforated plate installed at the opening of the circular groove 7. Then, press the plug rod 5 towards the mounting block 2, causing the strip plate 6 fixedly installed at the end of the plug rod 5 to slide through the strip-shaped perforated plate and extend into the interior of the circular groove 7, compressing the spring 11. Then, rotating the plug rod 5 causes the strip plate 6 fixedly installed at its end to rotate within the circular groove 7, thereby fixing the strip plate 6 to the opening of the circular groove 7. The slots of the perforated plate are staggered to limit the position of the perforated plate 6. Then, the insertion rod 5 is released and the push spring 11 pushes the insertion rod 5 to make the perforated plate 6 fit against the side wall of the perforated plate connected to the opening of the circular groove 7, thereby limiting the position of the protective cover 3. At the same time, when the protective cover 3 is installed, the rectangular sealing ring 9 is squeezed into the interior of the rectangular groove 8 by the protective cover 3, and the push spring 10 is compressed. At the same time, the push spring 10 pushes the rectangular sealing ring 9 to fit tightly against the side wall of the protective cover 3, thereby further improving the sealing between the mounting block 2 and the protective cover 3, and thus further improving the protective effect of the protective cover 3 on the plug-in component.
