Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and more specifically, to an electricity meter with terminals that are easy to plug and unplug. Background Technology

[0002] Electricity meters are instruments that measure and record electricity consumption and are an indispensable part of the power system. They accurately measure the electrical energy consumed by users, providing a basis for power companies to bill and for users to understand their own electricity usage. With the development of technology, many electricity meters integrate relays to achieve automatic control functions. For example, in prepaid electricity meters, when a user is in arrears, the relay can cut off the power supply, realizing remote fee control.

[0003] In actual use, workers need to insert wires into the relay's terminal interface and then fix the wires with bolts. Since fixing the wires with bolts is cumbersome, spring-type relays have been developed on the market. The opening and closing of the terminal interface can be controlled by pressing the spring assembly. However, when installing relay modules with many terminal interfaces (such as electricity meters used in factories or shopping malls, which may integrate multiple relay modules, and each module may contain a dozen or even dozens of terminal interfaces), pressing and assembling them one by one is still inefficient, which seriously affects the work efficiency of workers. Utility Model Content

[0004] The present invention provides an electricity meter with easy-to-plug terminals, which solves the problem that existing electricity meters are still inefficient when installing relay modules with many terminal interfaces (such as electricity meters used in factories or shopping malls, which may integrate multiple relay modules, and each module may contain a dozen or even dozens of terminal interfaces), and this seriously affects the work efficiency of the staff.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electricity meter with easy-to-plug terminals, comprising: an electricity meter assembly, the electricity meter assembly including a relay module, the relay module being provided with a wiring terminal module, the wiring terminal module including an insulating housing, the insulating housing being provided with a plurality of plug-in ports and a plurality of sliding grooves, the bottom of the sliding groove being provided with an elastic contact clip, the free part of the elastic contact clip extending into the corresponding plug-in port, and a plug rod being provided in the sliding groove, the plug rod being adapted to the elastic contact clip;

[0006] The insulating housing is provided with a switching mechanism, which includes a synchronization component 1. The synchronization component 1 includes a U-shaped plate, which is slidably disposed on the top of the insulating housing. A pull rod is provided on the side of the U-shaped plate near the insertion rod. A slot is provided on the insertion rod, and the slot is adapted to the pull rod.

[0007] In a preferred embodiment, a limiting groove is provided on the top of the insulating shell, a limiting rod is slidably disposed in the limiting groove, and a fixing groove is provided on the side of the U-shaped plate away from the insertion rod, the fixing groove being adapted to the limiting rod.

[0008] In a preferred embodiment, the switching mechanism further includes a second synchronization component, which includes a bracket disposed on the top of the insulating housing. Several L-shaped pull plates are slidably disposed on the bracket, and a second slot is provided on the insertion rod, with the L-shaped pull plates and the second slot being adapted to each other.

[0009] In a preferred embodiment, a slot is provided on one side of the L-shaped pull plate, and a connecting rod is provided on the opposite side of the slot on the L-shaped pull plate, the connecting rod being adapted to the slot.

[0010] In a preferred embodiment, slot one and slot two are staggered vertically.

[0011] In a preferred embodiment, the bracket is detachably connected to the insulating housing, and the L-shaped pull plate is detachably connected to the bracket.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model, by setting up a synchronization component, can synchronously control the opening and closing of all the squeezing elastic contact clips when a large number of wires need to be connected to the relay module during the installation of the meter assembly, effectively improving the installation efficiency of the workers.

[0014] This invention, by setting up a synchronization component two, enables the opening and closing of multiple elastic contact clips in a single operation when multiple insertions and removals of a certain number of wires at adjacent positions are required. This is achieved by splicing together a corresponding number of L-shaped pull plates, resulting in high flexibility in use. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 An electricity meter with easy-to-plug terminals includes: an electricity meter assembly 1, the electricity meter assembly 1 including a relay module 11, the relay module 11 being provided with a wiring terminal module 2, the wiring terminal module 2 including an insulating housing 21, the insulating housing 21 being provided with a plurality of plug-in ports 22 and a plurality of sliding grooves 23, the bottom of the sliding groove 23 being provided with an elastic contact clip 24, the free part of the elastic contact clip 24 extending into the corresponding plug-in port 22, and a plug rod 25 being provided in the sliding groove 23, the plug rod 25 being adapted to the elastic contact clip 24;

[0023] An insulating housing 21 is provided with a switching mechanism 3. The switching mechanism 3 includes a synchronization component 31. The synchronization component 31 includes a U-shaped plate 311. The U-shaped plate 311 is slidably disposed on the top of the insulating housing 21. A pull rod 312 is provided on the side of the U-shaped plate 311 near the insertion rod 25. A slot 26 is provided on the insertion rod 25. The slot 26 is adapted to the pull rod 312.

[0024] It should be noted that the U-shaped plate 311 and the pull rod 312 are detachably connected, and the length of the pull rod 312 can be adjusted according to the actual situation.

[0025] In this embodiment, the specific implementation scenario is as follows: when installing the meter assembly 1, a large number of wires need to be connected to the relay module 11. By pulling the U-shaped plate 311 and fixing it with the limiting rod 29, the pull rod 312 can be driven to pull all the plug rods 25 simultaneously. This causes the plug rods 25 to squeeze the elastic contact clip 24, causing the elastic contact clip 24 to undergo elastic deformation and align the interface on the elastic contact clip 24 with the plug-in port 22. At this time, the wires to be connected can be inserted into the corresponding plug-in port 22 in sequence and pass through the interface on the elastic contact clip 24. Then, the locking of the limiting rod 29 is released, so that the elastic contact clip 24 is reset, thereby firmly connecting the wires. At the same time, the U-shaped plate 311 is also reset simultaneously.

[0026] Furthermore, when it is necessary to repeatedly plug and unplug a certain number of wires in adjacent positions (e.g., 2 or 4), by splicing the corresponding number of L-shaped pull plates 322 and then moving them to the corresponding positions, the opening and closing of multiple elastic contact clips 24 can be controlled at one time, thereby significantly improving work efficiency.

[0027] Refer to the instruction manual appendix Figure 2 and Figure 3 In this embodiment, a limiting groove 28 is provided on the top of the insulating shell 21, and a limiting rod 29 is slidably arranged in the limiting groove 28. A fixing groove 313 is provided on the side of the U-shaped plate 311 away from the insertion rod 25, and the fixing groove 313 is adapted to the limiting rod 29.

[0028] It should be noted that the fixing groove 313 can be configured as an L-shape or other configurations with similar effects that are well known to those skilled in the art.

[0029] Refer to the instruction manual appendix Figure 3 and Figure 4 In this embodiment, the switching mechanism 3 further includes a second synchronization component 32, which includes a bracket 321. The bracket 321 is disposed on the top of the insulating housing 21. Several L-shaped pull plates 322 are slidably disposed on the bracket 321. The insertion rod 25 is provided with a second slot 27, and the L-shaped pull plates 322 are adapted to the second slot 27.

[0030] Refer to the instruction manual appendix Figure 3 and Figure 5 In this embodiment, a slot 323 is provided on one side of the L-shaped pull plate 322, and a connecting rod 324 is provided on the opposite side of the slot 323 on the L-shaped pull plate 322. The connecting rod 324 is adapted to the slot 323.

[0031] It should be noted that staff can assemble the corresponding number of L-shaped pull plates 322 according to the number of plug rods 25 of the single synchronous control switch, making it more convenient to use.

[0032] Refer to the instruction manual appendix Figure 4 and Figure 5 In this embodiment, the card slot 1 26 and the card slot 27 are staggered vertically.

[0033] It should be noted that interference between the L-shaped pull plate 322 and the pull rod 312 should be avoided;

[0034] Furthermore, sufficient redundant space is reserved between the pull rod 312 and the slot 26, and similarly, between the L-shaped pull plate 322 and the slot 27, to avoid interference when the synchronization components 31 and 32 operate separately.

[0035] Refer to the instruction manual appendix Figure 3 and Figure 5 In this embodiment, the bracket 321 is detachably connected to the insulating shell 21, and the L-shaped pull plate 322 is detachably connected to the bracket 321.

[0036] It should be noted that the number of L-shaped pull plates 322 installed on the bracket 321 can be adjusted according to the actual situation.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
