Description

Technical Field

[0001] This utility model relates to the field of data acquisition terminals for electricity meters, specifically to an electricity meter reading data acquisition terminal. Background Technology

[0002] Electricity meters are used to measure the electricity consumption of users or businesses. During the metering process, a data acquisition terminal is often needed to perform the measurement, avoiding the need for workers to collect data on-site. The data acquisition terminal can be used for remote measurement. The data acquisition terminal typically consists of a data acquisition module, a remote transmission module, a storage module, a communication module, an alarm module, and a power supply module. The data acquisition module uses RS485, and the electricity meter and the terminal are connected via a data acquisition line and a data link line. The communication module transmits data to the master station system via the data link line, realizing remote communication and control. The communication module is also responsible for receiving commands from the master station and sending them to the acquisition module. At the same time, it triggers an alarm and sends alarm information synchronously when there is an anomaly.

[0003] However, in existing technologies, the acquisition line and data link line are usually directly inserted into the terminal body, or sometimes the terminals are installed on the screw sleeve by screws for connection. This makes it difficult to disassemble the interface, and dust can easily enter the groove, thus affecting the contact quality of the terminals. Utility Model Content

[0004] The purpose of this utility model is to provide an electricity meter reading and data acquisition terminal to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a terminal body for collecting the electricity of the meter body. The terminal body is connected to the meter body via a collection line and a data link line. The bottom of the terminal body has two sets of grooves, and the collection line and the data link line are respectively connected in the two sets of grooves. The outer ring of the collection line and the data link line are equipped with a pre-fixing structure, and the inner wall of the groove is equipped with a snap-fit ​​structure, which snaps the pre-fixing structure.

[0006] Preferably, the top end of the acquisition line and the data link line is fixed with a contact end, which is connected to a terminal in the groove.

[0007] Preferably, the pre-fixed structure includes a positioning ring, a second protrusion, and a second arc-shaped locking block. The positioning ring is an L-shaped annular structure and is fitted around the outer ring of the acquisition line and the data link line. The second protrusion is located above the positioning ring and has two sets, which are symmetrically distributed around the central axis of the positioning ring. The second arc-shaped locking block has two sets, which are symmetrically distributed around the central axis of the positioning ring. The second arc-shaped locking block is fixed to the outer surface of the second protrusion, and the outermost ring size of the second arc-shaped locking block is smaller than the ring size of the positioning ring.

[0008] Preferably, the outer rings of the acquisition line and the data link line are fitted with a first limiting ring and a second limiting ring. The upper surface of the positioning ring is in contact with the lower surface of the second limiting ring, the lower surface of the positioning ring is in contact with the upper surface of the first limiting ring, and the second protrusion is fixed on the outer ring of the second limiting ring.

[0009] Preferably, the snap-fit ​​structure includes a protrusion and an arc-shaped snap-fit ​​block. The protrusion is fixed to the inner wall of the groove, and there are two sets of protrusions. The protrusions are distributed on the left and right sides of the groove, and the arc-shaped snap-fit ​​block is fixed to the side surface of the protrusion.

[0010] Preferably, the surface of the positioning ring is fitted with a sealing ring.

At this time, the contact ends of the acquisition line and data link line are in contact with the terminal. The arc-shaped locking block two on the outside of the limiting ring two is in contact with the arc-shaped locking block one. When it is pushed further in, the arc-shaped locking block two slides into the top of the arc-shaped locking block one. When disassembling, it can be pulled outwards. When plugging in, the sealing ring on the positioning ring is pressed against the bottom of the terminal body.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1 to 8 This utility model provides a technical solution: a meter reading and data acquisition terminal, including a terminal body 1 for collecting the electricity of the meter body 2. The data acquisition terminal body 1 is connected to the meter body 2 through a data acquisition line 3 and a data link line 4. Two sets of grooves 6 are provided at the bottom of the terminal body 1. Contact ends 7 are fixed at the top of the data acquisition line 3 and the data link line 4. The contact ends 7 are connected to the terminals in the grooves 6. The data acquisition line 3 and the data link line 4 are respectively connected in the two sets of grooves 6.

[0025] Specifically, the terminal body 1 consists of a data acquisition module, a remote transmission module, a storage module, a communication module, an alarm module, and a power supply module. The terminal body 1 connects to the data interface of the electricity meter via the acquisition line 3. The power supply module, connected to an external power source via the power supply wire 5, provides stable power to the entire unit and simultaneously powers the communication interface of the electricity meter. The data acquisition module uses an RS-485 interface. Under the scheduling of the communication module, it acquires the electricity consumption data output by the electricity meter from the acquisition line 3 according to a set timing sequence and transmits it to the storage module in real time. The storage module uses a FLASH memory chip. While collecting new data, historical records are retained to provide a basis for subsequent anomaly comparisons. After the collected data is parsed and determined to be valid by the communication module, the result is sent to the remote transmission module and transmitted to the main station system via data link line 4. The main station can return parameter configuration or control commands. After receiving the command, the terminal reissues it to the data acquisition module through the communication module to achieve remote scheduling. If voltage, current, or communication abnormalities are detected during the acquisition process, the communication module will immediately trigger the alarm module. In addition to issuing audible and visual prompts locally, the alarm module will also send the alarm information to the main station along with the data through the remote transmission module.

[0026] Example 2

[0027] Based on Embodiment 1, in order to achieve rapid installation of the wires onto the terminals, a pre-fixing structure is proposed for the outer rings of both the acquisition line 3 and the data link line 4. The pre-fixing structure includes a positioning ring 10, a second protrusion 14, and a second arc-shaped locking block 15. The positioning ring 10 is an L-shaped annular structure, fitted onto the outer rings of the acquisition line 3 and the data link line 4. The second protrusion 14 is located above the positioning ring 10, and there are two sets of the second protrusion 14, symmetrically distributed about the central axis of the positioning ring 10. There are also two sets of the second arc-shaped locking blocks 15, symmetrically distributed about the central axis of the positioning ring 10. The second arc-shaped locking blocks 15 are fixed to the outer surface of the second protrusion 14. The outermost dimension of the second arc-shaped locking block 15 is smaller than the annular dimension of the positioning ring 10. Limiting devices are fitted onto the outer rings of both the acquisition line 3 and the data link line 4. Ring 12 and limiting ring 2 13, the upper surface of positioning ring 10 is in contact with the lower surface of limiting ring 2 13, the lower surface of positioning ring 10 is in contact with the upper surface of limiting ring 12, protrusion 2 14 is fixed on the outer ring of limiting ring 2 13, the inner wall of groove 6 is equipped with a snap-fit ​​structure, the snap-fit ​​structure includes protrusion 1 8 and arc-shaped snap-fit ​​block 1 9, protrusion 1 8 is fixed on the inner wall of groove 6, and there are two sets of protrusion 1 8, which are distributed on the left and right sides of groove 6, and arc-shaped snap-fit ​​block 1 9 is fixed on the side surface of protrusion 1 8, the surface of positioning ring 10 is embedded with sealing ring 11, when acquisition line 3 and data link line 4 are inserted into groove 6, sealing ring 11 is in contact with the outer surface of terminal body 1, arc-shaped snap-fit ​​block 2 15 and arc-shaped snap-fit ​​block 1 9 are tangent, and arc-shaped snap-fit ​​block 2 15 is located above arc-shaped snap-fit ​​block 1 9, the snap-fit ​​structure snaps the pre-fixed structure;

[0028] Specifically, during use, the contact ends 7 of the acquisition line 3 and the data link line 4 are aligned with the groove 6 of the terminal body 1 and pushed in. As the connection is made, the contact end 7 first makes reliable contact with the terminal. Then, the arc-shaped locking block 15 on the limiting ring 13 contacts the arc-shaped locking block 9 and slides along its surface. When force is applied, the arc-shaped locking block 15 passes over the arc-shaped locking block 9 and locks onto it, achieving a stable lock. At the same time, the sealing ring 11 on the positioning ring 10 is pressed against the bottom of the terminal body 1, and the positioning ring 10 is inserted into the groove 6, forming a sealing barrier to prevent external dust from entering the groove 6 and affecting the terminal contact. During disassembly, simply pull outwards in the opposite direction of insertion. After the arc-shaped locking block 15 disengages from the arc-shaped locking block 9, it can be easily removed, completing a quick disconnection without the need for additional tools.

[0029] During use, the acquisition line 3 and data link line 4 are slowly pushed into the groove 6 of the terminal body 1, aligned with the groove. As they are pushed in, the arc-shaped locking block 15 in the pre-fixed structure gradually contacts and slides onto the locking structure. When sufficient force is applied, the arc-shaped locking block 15 passes over the locking structure and securely engages, achieving a reliable connection between the acquisition line 3 and data link line 4 and the terminal body 1. Simultaneously, the sealing ring 11 is compressed, forming an effective sealing barrier to prevent external dust and impurities from entering and ensuring the stability of the terminal contact. For disassembly, simply pull out in the opposite direction of insertion. The arc-shaped locking block 15 will disengage from the locking structure and exit smoothly, completing a quick disconnection. The entire process is simple and requires no auxiliary tools, improving the efficiency and reliability of connection and disassembly.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
