Description

Technical Field

[0001] The utility model belongs to the technical field of electric power measurement and instruments, in particular to a plug-in interface for an intelligent electric meter error estimation device. Background Art

[0002] With the continuous deepening of smart grid construction, smart meters, as an indispensable part of the power system, are crucial to the stable operation of the power system with their accurate measurement and transmission of electric energy information.

[0003] However, due to various reasons such as equipment aging, environmental factors and human operation, smart meters may face a series of challenges in actual applications. Among them, the design of the plug interface is particularly critical, because unreasonable plug interface design can easily lead to problems such as unstable wire connection and easy falling off, which will not only affect the normal operation of the smart meter, but also have a negative impact on the accuracy and reliability of error estimation. In addition, when the plug interface is not in use, if there is a lack of effective dust protection measures, dust and debris can easily enter the interface, causing poor contact, circuit damage and other problems, increasing the maintenance cost of the equipment. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a plug-in interface for an error estimation device of a smart electric meter.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plug interface for a smart meter error estimation device, comprising a protective shell, a dust cover, a fixed lock, a plug, two clamping mechanisms and two fastening mechanisms;

[0006] The protective shell is hinged to the dust cover, the dust cover is hinged to the fixed lock, the fixed lock is provided with a plug, the protective shell is provided with a socket, the plug and the socket are used in conjunction with each other, the inner wall of the protective shell is provided with two clamping mechanisms, the two clamping mechanisms are symmetrically arranged, the inner wall of the dust cover is provided with two sliding grooves, each sliding groove is provided with a fastening mechanism, and the two fastening mechanisms are symmetrically arranged.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. Enhance the stability and safety of wires: Through the dual functions of the clamping mechanism and the fastening mechanism, it can ensure that the wires are stable after being inserted into the interface and are not easy to fall off or shift, thereby greatly improving the stability and safety of the wire connection.

[0009] 2. Dust-proof protection: The designed dust cover can close the plug interface when it is not in use, effectively preventing dust from entering, keeping the interior clean, and extending the service life of the interface.

[0010] 3. Easy operation: The design of the clamping mechanism and the fastening mechanism makes the wire connection process simple and convenient. The user only needs to open the dust cover, align the wire with the socket and insert it, and then tighten it by pulling the pull rod. There is no need to use other tools or perform complicated operations.

[0011] 4. Strong applicability: The design of the clamping mechanism and the fastening mechanism has a certain degree of versatility and can adapt to wires of different specifications and sizes, thus improving the applicability of the plug interface.

[0012] 5. Protect wires: The design of anti-slip pads and grooves can reduce wear and damage to wires during clamping and tightening, protecting the integrity of wires.

[0013] 6. Safety lock: The setting of the fixed lock ensures the stability of the dust cover when closed, preventing the possibility of accidental opening and dust ingress, further enhancing the safety and reliability of the interface.

[0014] In summary, the plug-in interface for the smart meter error estimation device shows significant beneficial effects in enhancing the stability of wire connection, improving safety, simplifying operation procedures, enhancing applicability, protecting wires, and ensuring interface closure.

[0018] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] This embodiment describes a plug interface for a smart meter error estimation device, including a protective shell 1, a dust cover 2, a fixing lock 3, a plug 4, two clamping mechanisms and two fastening mechanisms;

[0020] The protective shell 1 is hinged to the dust cover 2, the dust cover 2 is hinged to the fixing lock 3, the fixing lock 3 is provided with a plug 4, the protective shell 1 is provided with a socket, the plug 4 is used in conjunction with the socket, the inner wall of the protective shell 1 is provided with two clamping mechanisms, the two clamping mechanisms are symmetrically arranged, the inner wall of the dust cover 2 is provided with two sliding grooves, each sliding groove is provided with a fastening mechanism, and the two fastening mechanisms are symmetrically arranged.

[0021] Each of the clamping mechanisms comprises a movable plate 5 and an anti-slip pad 6;

[0022] One end of the movable plate 5 is connected to the inner wall of the protective shell 1 through a torsion spring, and the other end of the movable plate 5 is provided with an anti-slip pad 6.

[0023] Each of the fastening mechanisms comprises a pull rod 7, a spring 8 and a clamping plate 9;

[0024] The pull rod 7 is slidably set in the corresponding slide groove, the pull rod 7 is fixedly connected to the splint 9, the splint 9 is slidably set in contact with the inner wall of the dust cover 2, the spring 8 is sleeved on the pull rod 7, the outer wall of one end of the spring 8 is fixedly connected to the inner wall of the slide groove, the inner wall of the other end of the spring 8 is fixedly connected to the outer wall of the pull rod 7, and a groove is provided on the splint 9.

[0025] When using the utility model, open the fixed lock 3 to open the dust cover 2, revealing the socket and the clamping mechanism in the protective shell 1, and insert the wires to be connected into the protective shell 1. After the wires enter the protective shell 1, the movable plates 5 of the two clamping mechanisms automatically clamp the wires through the elastic force of the torsion spring, and the anti-slip pads 6 provide additional friction to prevent the wires from slipping. Then, pull the pull rods 7 of the two fastening mechanisms toward the far end to move the clamping plates 9 to both sides. At the same time, the spring 8 is compressed to place the wires in the groove between the two clamping plates 9, release the pull rod 7, and the spring 8 rebounds to push the clamping plates 9 to move toward the center, and the wires are fastened in the groove for a second time. When the plug interface is not in use, the protective shell 1 can be sealed by the dust cover 2 to prevent dust from entering and keep the interior clean.
