Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an electricity meter that is easy to wire. Background Technology

[0002] In the current field of electricity meter technology, the wiring process of electricity meters has always been a crucial part of power installation and maintenance. Traditional electricity meter designs are usually equipped with terminals for connecting external power lines or load lines. However, in practice, the use of these terminals has some obvious shortcomings.

[0003] When wiring, workers first insert one end of the copper wire into the corresponding hole of the terminal block. To ensure a good electrical connection between the copper wire and the terminal, the other hand must then be used to tighten the bolt to secure the copper wire firmly to the terminal. During this process, because the copper wire needs to maintain a certain tension to ensure full insertion and good contact, workers often need to hold the copper wire with one hand while operating the tightening bolt with the other.

[0004] This wiring method is not only cumbersome but also inefficient. More importantly, because it requires coordinating two hands for different operations simultaneously, workers are prone to fatigue and errors, leading to loose connections or damage to the meter's terminals. Furthermore, for large meters requiring multiple lines, this wiring method is even more time-consuming and labor-intensive, significantly increasing the difficulty of installation and maintenance. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to provide an energy meter that is easy to wire, thus solving the problems mentioned in the background above.

[0007] (II) Technical Solution

[0008] An easy-to-wire electricity meter includes an electronic meter body. The bottom of the electronic meter body is provided with multiple sets of connection terminals, and the outer surfaces of these connection terminals are provided with multiple sets of fastening bolts. The bottom ends of all the connection terminals are connected to wiring conduits, and the outer surfaces of the wiring conduits are connected to a housing. Both sides of the housing are connected to connecting pipes, and an external circular plate is fixedly installed on one side of the outer surface of each connecting pipe. A first spring is connected to one side of the external circular plate, and a clamping rod is connected to one end of the first spring. A clamping block is connected to one end of the clamping rod, and a limit block is fixedly installed at the bottom end of the clamping block. A push plate is connected to one end of the limit block. A groove is formed on the bottom outer surface of the connecting pipe, and the inner wall of the groove movably engages with the limit block.

[0009] Preferably, a groove is formed on the outer surface of one end of the clamping rod, and a second spring is installed in the groove, with a locking pin connected to one end of the second spring.

[0010] Preferably, a groove is formed on one side of the outer surface of the connecting pipe, and a locking pin is movably engaged on the inner wall of the groove.

[0011] Preferably, a connecting bracket is fixedly installed at the bottom of the electronic watch body, and the connecting bracket is installed on the outer surface of multiple sets of wiring conduits.

[0012] Preferably, one end of the clamping block has an arc-shaped groove.

[0013] Preferably, the outer surface of the clamping block is covered with rubber.

[0014] Preferably, the two ends of the connecting frame are arc-shaped.

[0015] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0016] 1. This utility model utilizes a clamping block to hold the rubber sheath at the outer end of the copper wire. The arc-shaped groove design at one end of the clamping block better conforms to the shape of the copper wire, increasing the stability and reliability of the clamping. Simultaneously, the rubber material covering the outer surface of the clamping block increases friction, preventing the copper wire from slipping or falling off during clamping.

[0017] 2. This utility model guides the copper wire to the connection hole of the terminal block through a wiring conduit, making the wiring process more orderly and intuitive. It effectively reduces wiring errors caused by messy wiring, lowering safety hazards. At the same time, the clamping block allows operators to easily hold the copper wire, further simplifying the wiring steps and improving wiring efficiency. Attached Figure Description

It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] An easy-to-wire electricity meter includes an electronic meter body 1. The bottom of the electronic meter body 1 is provided with multiple sets of connection terminals 2, and the outer surface of the multiple sets of connection terminals 2 is provided with multiple sets of fastening bolts 3. The bottom of each set of connection terminals 2 is connected to a wiring conduit 5, and the outer surface of the wiring conduit 5 is connected to a housing 6. Both sides of the housing 6 are connected to connecting pipes 7, and an external circular plate 8 is fixedly installed on one side of the outer surface of the connecting pipe 7. The external circular plate 8 facilitates the operation of a clamping rod 914 by the operator. A first spring 916 is connected to one side of the external circular plate 8, and one end of the first spring 916 is connected to the clamping rod 914. One end of the clamping rod 914 is connected to a clamping block 915. A limit block 913 is fixedly installed at the bottom of the clamping block 915, and one end of the limit block 913 is connected to a push plate 912. A groove 911 is opened on the bottom outer surface of the connecting pipe 7, and the inner wall of the groove 911 is movably engaged with the limit block 913.

[0027] Furthermore, a groove is formed on the outer surface of one end of the clamping rod 914, and a second spring is installed in the groove. One end of the second spring is connected to a locking pin 9, which is detachably engaged with the slot 711 on the connecting tube 7 via the locking pin 9. When it is necessary to clamp the copper wire, the clamping rod 914 can be unlocked by pressing the locking pin 9, which is simple and quick to operate. At the same time, the second spring provides a restoring force for the locking pin 9, ensuring that it can return to the engaged position, increasing the stability and reliability of the structure.

[0028] Furthermore, a groove 711 is provided on one outer surface of the connecting tube 7, and a locking pin 9 is movably engaged within the inner wall of the groove 711. The groove 711 provides a clear engagement position for the locking pin 9, ensuring the stability and firmness of the clamping rod 914 in the locked state. This design helps prevent the clamping block 915 from accidentally loosening or falling off during wiring, thereby improving the safety and reliability of the wiring.

[0029] Furthermore, a connecting bracket 4 is fixedly installed at the bottom of the electronic watch body 1, and the connecting bracket 4 is installed on the outer surface of multiple sets of wiring conduits 5. The connecting bracket 4 not only provides a stable support for the wiring conduits 5, but also makes the entire wiring structure more compact and orderly.

[0030] Furthermore, one end of the clamping block 915 is provided with an arc-shaped groove, which can better fit the shape of the copper wire and increase the contact area and friction between the clamping block 915 and the copper wire.

[0031] Furthermore, the outer surface of the clamping block 915 is covered with rubber. The rubber material has good elasticity and friction, which can increase the contact tightness and stability between the clamping block 915 and the copper wire.

[0032] Furthermore, the two ends of the connecting frame 4 are arc-shaped. The arc-shaped design can reduce the interference and collision of the connecting frame 4 with the surrounding environment during installation and use, thereby improving the safety and durability of the entire structure.

[0033] Working principle: When using this easy-to-wire electricity meter, the operator first needs to pass the copper wire to be connected through the wiring conduit 5, ensuring that the copper wire can smoothly reach the connection hole of the connection terminal 2. This design makes the wiring process more orderly and intuitive, reducing wiring errors caused by messy wiring.

[0034] Next, connect the exposed portion of the copper wire into the connection hole of terminal 2 to ensure the reliability and stability of the electrical connection. At this point, because the rubber sheath of the copper wire is slippery, direct tightening may cause loosening or instability.

[0035] To solve this problem, the operator presses the locking pin 9, utilizing the elasticity of the second spring to cause the locking pin 9 to retract and disengage from the locking groove 711 on the connecting tube 7, thereby unlocking the clamping rod 914. After unlocking, the clamping rod 914 can move flexibly and provide clamping force under the elastic force of the first spring 916.

[0036] Subsequently, the operator adjusts the clamping block 915 at the end of the clamping rod 914 to a suitable position so that it can clamp the rubber sheath at the outer end of the copper wire. The arc-shaped groove design at one end of the clamping block 915 can better conform to the shape of the copper wire, increasing the stability and reliability of the clamping. At the same time, the rubber material covering the outer surface of the clamping block 915 can increase friction and prevent the copper wire from slipping or falling off during the clamping process.

[0037] Once the clamping block 915 successfully holds the copper wire, the operator can easily rotate the fastening bolt 3 to secure the connecting terminal 2 to the copper wire, completing the entire wiring process. This design not only simplifies the wiring steps and improves wiring efficiency but also ensures the reliability and safety of the wiring.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
