Description

Technical Field

[0001] This invention relates to the field of electricity metering and power construction tools, specifically to an intelligent integrated wiring device for electricity meters and its working method. Background Technology

[0002] In the installation, replacement, and routine maintenance of electricity meters, power construction workers need to perform a series of operations, including measuring line current, stripping cable insulation, and tightening terminal screws. In traditional work methods, these operations are performed using multiple independent tools. Construction workers need to carry various tools such as clamp meters, wire strippers, and screwdrivers, which not only increases the burden of carrying and managing tools but also requires frequent tool switching during operation, reducing construction efficiency.

[0003] Clamp-on ammeters are specialized instruments for measuring alternating current. Their core structure consists of a toroidal iron core formed by movable and fixed clamps. During measurement, the movable clamp opens and fits onto the cable under test; when closed, it forms a complete magnetic circuit, inducing an electromotive force proportional to the current. Existing clamp-on ammeters have relatively limited functionality, only capable of current measurement and unable to assist in other construction tasks such as cable stripping and screw tightening. In electricity meter wiring installation, current measurement and cable stripping are often sequential processes. Integrating these two functions would significantly reduce tool switching frequency and improve work efficiency. Wire strippers are specialized tools for removing cable insulation. Their core structure consists of two opposing clamp arms. Pressing the handle brings the arms closer together, and the blades cut into the insulation layer before pulling outwards to peel it off. Existing wire strippers are standalone handheld tools, lacking structural integration with current measuring tools. Tightening the screws on the terminals of an electricity meter requires tools such as screwdrivers, and some cable terminals also require the use of sockets or wrenches, further increasing the variety and quantity of tools.

[0004] However, conventional electricity meter wiring tools still have the following shortcomings in terms of structural design, installation, and use: 1. Insufficient integration; there is no dedicated tool that organically integrates the three core functions of current measurement, cable stripping, and screw tightening into one unit. 2. The inconvenience of switching and disassembling various functional modules reduces the flexibility of using the tool in different construction scenarios. Summary of the Invention

[0005] In order to solve the technical problems existing in the background art, the present invention provides an intelligent integrated wiring device for electricity meters and its working method, which integrates the three functions of current measurement, cable stripping and screw tightening into one, and has the functions of current measurement, cable stripping and screw tightening.

[0006] The technical solution adopted by this invention is: The smart integrated wiring device for electricity meters includes: The clamp meter body has a movable clamp and a fixed clamp at the front end. The movable clamp and the fixed clamp are provided with an iron core and a coil wound around the iron core and electrically connected to the measuring mechanism inside the clamp meter body.

[0007] The lower end of the clamp meter body is fixedly equipped with a detachable wire stripper or a rotary motor. The wire stripper is used to strip non-energized cables. The rotary motor has a self-locking chuck that extends rearward along its rotation axis and is coaxially driven.

[0008] The clamp meter body is provided with a drive mechanism for driving the movable clamp and wire stripper to move, including: a pressing block extending out of the clamp meter body, and a front fork and a rear fork extending from the front and rear ends of the pressing block, respectively. The front fork is used to control the opening and closing of the movable clamp, and the rear fork is used to control the opening and closing of the wire stripper.

[0009] Furthermore, the fixed clamp is configured as a curved wall fixedly connected to the clamp meter body, and the movable clamp is configured as a straight arm hinged to the clamp meter body; the iron cores at the ends of the movable clamp and the fixed clamp abut against each other and form a ring that can be sleeved on the outside of the live cable.

[0010] Furthermore, the rear end of the movable clamp is provided with an extension arm, the end of which is fixedly provided with a front derailleur shaft, which extends downward and is movably inserted into the front derailleur fork.

[0011] Furthermore, a mounting rod protrudes from the rear side of the lower end of the clamp-on watch body, and the mounting rod extends downward.

[0012] The wire stripper is provided with a rear deflector shaft and a mounting hole. The rear deflector shaft and the mounting hole are symmetrically arranged on the two arms of the wire stripper. The rear deflector shaft is movably inserted into the rear deflector fork, and the mounting hole is coaxially inserted into the mounting rod.

[0013] Furthermore, a base plate is fixedly provided at the lower end of the clamp meter body, and a mounting box is fixedly provided at the lower end of the base plate. The mounting box has an opening facing rearward, and the rotary motor is movably inserted into the mounting box. A slot is protruding on the side wall of the rotary motor. The slot is a U-shaped slot with an opening facing forward. Snap-fit ​​protrusions are provided on both sides of the slot opening to snap and fix the rotary motor to the outside of the mounting rod.

[0014] Furthermore, the pressing block is slidably clamped between the lower end of the clamp-shaped watch body and the upper end of the base plate.

[0015] Furthermore, the lower end of the clamp-type watch body is provided with a groove, the pressing block is movably disposed in the groove, and a thrust spring is provided on the end face of the pressing block to abut against the groove wall.

[0016] Furthermore, an isolation plate is provided on the groove wall of the clamp-type watch body; the pressing block is composed of a front pressing block and a rear pressing block disposed on both sides of the isolation plate, and the front pressing block and the rear pressing block are fixedly connected to the front shift fork and the rear shift fork, respectively; two sets of thrust springs are arranged side by side in the front-rear direction and abut against the rear end faces of the front pressing block and the rear pressing block, respectively.

[0017] Furthermore, a limiting block is fixedly provided at the upper end of the base plate. Two limiting blocks are provided at the edge of the base plate near the movable clamp side, which respectively abut against the front shift fork and the rear shift fork.

[0018] The working method of the smart integrated wiring device for electricity meters includes: A. Initial state: The pressing block is in the outermost position under the action of the thrust spring. The front and rear shift forks move the front and rear shift shafts respectively until they abut against the two limit blocks, so that the movable clamps approach the fixed clamps and form a ring. The two clamp arms of the wire stripper are in the open state.

[0019] B. Cable installation status: Pressing the pressing block causes the front and rear shift forks to move away from the two limit blocks, and the front and rear shift shafts to move respectively; the movable clamp moves away from the fixed clamp and opens, thus fitting over the live cable, and the current is measured when it returns to the initial state; the two clamp arms of the wire stripper move closer to each other, thus stripping the wire from the non-live cable.

[0020] C. Fastening construction status: Remove the wire strippers from the clamp meter body 10 along the mounting rod axis; push the rotary motor inside the mounting box until the slot on the side wall of the rotary motor engages with the outside of the mounting rod, and control the rotation of the self-locking chuck at the rear end of the rotary motor by the button on the outer wall of the rotary motor.

[0021] The beneficial effects of the intelligent integrated wiring device for electricity meters and its working method of the present invention are as follows: 1. Based on the operational sequence of power construction, the core functions of clamp ammeter, wire stripper and electric screwdriver are integrated into one, reducing the number of tools that construction personnel need to carry, reducing the burden of carrying tools and simplifying tool management.

[0022] 2. Depending on the actual usage, the linkage structure of the pressing block, front fork, and rear fork of the drive mechanism can be selected to simultaneously complete the opening of the movable clamp and the closing of the wire stripper, and automatically reset after being released; the movable clamp and wire stripper can also be controlled separately by the front pressing block and the rear pressing block.

[0023] 3. The wire stripper is fixed by the insertion of the mounting hole and the mounting rod, and can be quickly assembled and disassembled according to construction needs; the rotating motor is inserted into the mounting box and fixed by the slot and the mounting rod, and the tightening function of the screw can be expanded as needed; thus, it can adapt to the needs of different construction scenarios.
