Description

Technical Field

[0001] This utility model relates to the field of power system automation technology, specifically to a meter position wire clamp. Background Technology

[0002] With the development of society and the economy, the importance of electricity to life is self-evident. It permeates almost every corner of our lives, from basic lighting and the use of household appliances to industrial production, transportation, medical care, scientific research, education and other fields. Electricity plays an indispensable role, and "uninterrupted power supply" has become a necessity.

[0003] Due to the massive number of low-voltage electricity meters to be replaced, prolonged power outages are required during the replacement process, severely impacting people's quality of life and even leading to customer complaints. Therefore, a customer-perceived meter replacement method—uninterrupted power replacement—has emerged.

[0004] However, the various low-voltage uninterrupted power supply (UDPS) meter replacement devices currently on the market have three major shortcomings in practical applications. First, their applicable scenarios are narrow. Some popular base-plate type UDPS meter replacement keys consist of a plug-in base plate and a replacement key, requiring sufficient space for installation. However, for scattered single-meter boxes in islands and remote towns, the replacement device is too large; the plug-in base plate extends beyond the meter's outer frame by a certain width, and the replacement key extends beyond the meter cover by a certain thickness, preventing the meter box from closing. Second, for existing electricity meters, the above replacement method requires installing the base plate first, and only after the base plate is installed can the meter be replaced without interrupting power. This results in a power outage during the application of the replacement device—power outage first, then meter removal, and finally installation of the UDPS meter replacement device and the electricity meter. Furthermore, the process is cumbersome, time-consuming, and labor-intensive, still unable to achieve uninterrupted meter replacement in a short time.

[0005] Therefore, a meter position wire clamp is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a meter position wire clamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a meter position wire clamp, comprising a housing and a conversion mechanism assembly, wherein the housing comprises an anti-tamper screw buckle, an anti-foolproof cover, an insulating lower baffle, a terminal retainer base, a hook-and-unhook fixing buckle, and an insulating upper baffle; the conversion mechanism assembly comprises an insulating telescopic sleeve, a spring, a brass insulating terminal, a cable protection pad, and a brass lever.

[0008] The lower insulating baffle is fixed to the rear side of the terminal retainer base, the upper insulating baffle is fixed to the front side of the terminal retainer base, the anti-fool cover is fixed to the upper side of the terminal retainer base, the anti-tamper screw is fixed to the upper side of the anti-fool cover, and the interior of the terminal retainer base is provided with evenly arranged mounting cavities.

[0009] The cable protection pad is located at the lower end of the brass insulated terminal. The cable protection pad and the brass insulated terminal are snapped into the inside of the mounting cavity. An insulating telescopic sleeve is sleeved on the outside of the brass insulated terminal. A spring is sleeved between the brass insulated terminal and the insulating telescopic sleeve. A sliding groove is opened on the upper side of the terminal holder base at the upper end of the mounting cavity. The brass lever is slidably disposed inside the sliding groove. Symmetrical hook-and-unhook fasteners are fixed on the lower side of the terminal holder base.

[0010] Preferably, the upper side of the terminal retainer base has symmetrical threaded holes, and the lower ends of the two anti-tamper screws are threadedly connected to the threaded holes. The anti-fouling cover is fixedly connected to the terminal retainer base through the adaptation of the anti-tamper screws and the threaded holes.

[0011] Preferably, the side wall of the insulating upper baffle is provided with evenly arranged circular holes, and the evenly arranged insulating telescopic sleeves all pass through the circular holes and extend to the outside.

[0012] Preferably, the side wall of the insulating lower baffle is provided with evenly arranged wiring holes.

[0013] Preferably, the side walls of the lower insulating baffle and the upper insulating baffle are provided with first screw fixing holes, and the front and rear sides of the terminal retainer base are provided with second screw fixing holes corresponding to the first screw fixing holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The electric shock prevention safety design in this application, consisting of components such as insulating telescopic sleeves and springs, features a spring-structured insulating sleeve for the pin-type terminals. After insertion into the meter, it automatically retracts into the housing, effectively avoiding the risk of electric shock during live meter replacement and maintenance, and preventing accidental electric shock accidents. It boasts high adaptability, a compact overall structure, and small size, making it suitable for installation and removal in any space. No need to replace the electrical box, meeting the space requirements of standard meter boxes. The foolproof structure ensures efficient and safe meter replacement and maintenance. By improving the accuracy and reliability of meter wiring, problems caused by wiring errors, such as damage to metering equipment and loss of electricity data, are reduced. The wiring error rate can be reduced to below 2%, improving construction safety and user electricity safety. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A meter position cable clamp includes a housing and a conversion mechanism assembly. The housing includes an anti-tamper screw cap 101, a foolproof cover 102, an insulating lower baffle 103, a terminal retainer base 104, a hook-and-unhook fixing buckle 105, and an insulating upper baffle 106. The conversion mechanism assembly includes an insulating telescopic sleeve 201, a spring 202, a brass insulating terminal 203, a cable protection pad 204, and a brass lever 205.

[0026] The lower insulating baffle 103 is fixed to the rear side of the terminal retainer base 104, the upper insulating baffle 106 is fixed to the front side of the terminal retainer base 104, the anti-fool cover 102 is fixed to the upper side of the terminal retainer base 104, the anti-tamper screw buckle 101 is fixed to the upper side of the anti-fool cover 102, and the interior of the terminal retainer base 104 is provided with evenly arranged mounting cavities.

[0027] A cable protection pad 204 is installed at the lower end of the brass insulated terminal 203. The cable protection pad 204 and the brass insulated terminal 203 are locked inside the mounting cavity. An insulating telescopic sleeve 201 is sleeved on the outside of the brass insulated terminal 203. A spring 202 is sleeved between the brass insulated terminal 203 and the insulating telescopic sleeve 201. A sliding groove is opened on the upper side of the terminal retainer base 104 at the upper end of the mounting cavity. A brass paddle 205 is slidably installed inside the sliding groove. Symmetrical hook-and-unhook fasteners 105 are fixed on the lower side of the terminal retainer base 104.

[0028] During installation, first assemble the internal conversion mechanism components of the cable clamp. First, assemble the cable protection pad 204 to the lower end of the brass insulated terminal 203, then install the two assembled components into the terminal retainer base 104. Next, lock the lower insulating baffle 103 to the terminal retainer base 104 and install it on the lower part of the brass insulated terminal 203 to prevent it from falling out. Then, install the insulating telescopic sleeve 201 and spring 202 on the exposed brass insulated terminal 203 on the upper part of the device. Slide the spring 202 onto the upper end of the brass insulated terminal 203, and then place the insulating telescopic sleeve 201 on the brass insulated terminal 203. Finally, lock the upper insulating baffle 106 to the upper end of the terminal retainer base 104 to complete the fixed installation of the spring 202 and the insulating telescopic sleeve 201. Finally, install the brass lever 205 and the anti-fool cap 102 into the terminal retainer base 104 to complete the assembly of the device.

[0029] The device uses pin-type terminals that slide directionally along the housing grooves to solidify standard wiring methods, ensuring accurate and quick meter connection. Its simple and intuitive structure facilitates safe operation, eliminating the risk of incorrect wiring and enabling rapid and error-free meter replacement and maintenance. The foolproof cover 102 features a safety mechanism: when not in use, the brass tabs 205 on both sides are at their furthest positions. At this point, the foolproof cover 102 can be inserted. An internal stop within the cover prevents the brass tabs 205 from moving to the right or left and causing an accident. The cover 102 can only be installed smoothly after the brass tabs 205 have been properly reset. During use, simply move the brass tabs 205 to their furthest positions and connect them to their corresponding locking positions. After installation, they must be reset before the foolproof cover 102 can be properly installed.

[0030] The terminal retainer base 104 has symmetrical threaded holes on its upper side. The lower ends of the two anti-tamper screw caps 101 are threadedly connected to the threaded holes. The anti-fool cover 102 is fixedly connected to the terminal retainer base 104 through the matching of the anti-tamper screw caps 101 and the threaded holes. By rotating the anti-tamper screw caps 101, the internal screws are threadedly connected to the threaded holes, thereby realizing the installation and fixation of the anti-fool cover 102.

[0031] The side wall of the insulating upper baffle 106 is provided with evenly arranged round holes, and the evenly arranged insulating telescopic sleeves 201 all pass through the round holes and extend to the outside, so as to facilitate plugging in with the electricity meter.

[0032] The side wall of the insulating lower baffle 103 is provided with evenly arranged wiring holes.

[0033] Both the lower insulating baffle 103 and the upper insulating baffle 106 have first screw fixing holes on their side walls, and the terminal retainer base 104 has second screw fixing holes on its front and rear sides corresponding to the first screw fixing holes.

[0034] Working principle:

[0035] During installation and use, align the brass insulated terminal 203 of the wire clamp with the meter's wire slot, insert and tighten the wire slot screw. During insertion, the top of the insulating telescopic sleeve 201 presses against the meter's wire slot; as it retracts, the brass insulated terminal 203 can be inserted into the meter's wire slot. Next, connect the lower end of the wire clamp to the incoming power line and cable. If the meter is damaged or has reached its service life and needs replacement, open the anti-misoperation cover 102 of the wire clamp, and move the brass lever 205 inward (right and left) to jumper the incoming power line. At this time, the meter will no longer be powered. The meter can then be replaced. After replacement, move the brass lever 205 back to its original position (moving it right and left resets the lever 205). Finally, reinstall the anti-misoperation cover 102. This completes the meter replacement without interrupting power.
