Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, in particular to an electric energy meter which is convenient for separation and assembly. Background Art

[0002] An energy meter is a meter used to measure electrical energy consumption. It is usually installed at the power entrance of a home or business. It can record electricity consumption so that users can understand their electricity consumption and provide a basis for electricity bill settlement. There are two main types of energy meters: mechanical and electronic.

[0003] When connecting the cable to the electric energy meter, the insulation layer at the end of the cable needs to be cut off to expose the conductive wire inside so that the conductive wire is electrically connected to the electric energy meter. The installation of the electric energy meter needs to follow certain steps and safety specifications. The following is the general installation process: 1. Choose a suitable location: The electric energy meter should be installed in an easily accessible and well-ventilated place to avoid moisture and high temperature; 2. Power off: Before installation, be sure to cut off the power supply to ensure safety; 3. Prepare tools and materials: You need to prepare tools and materials such as screwdrivers, cables, and terminal blocks; 4. Wiring: According to the wiring diagram of the electric energy meter, connect the incoming and outgoing lines to the corresponding terminals to ensure a firm connection to avoid short circuits; 5. Installation and fixation: Fix the electric energy meter on a wall or a special bracket to ensure stability; 6. Check the wiring: Check all wiring again before powering on to ensure that there is no loose or incorrect connection.

[0004] When connecting cables, in order to improve the safety and reliability of electrical connections, it is also necessary to twist the conductive wires in the cable into a bundle. The main reasons are as follows: 1. Enhanced conductivity: Twisting multiple conductive wires into a bundle can reduce contact resistance, improve conductivity, and ensure that current can pass smoothly; 2. Improved mechanical strength: After twisting into a bundle, the overall mechanical strength of the conductive wires is enhanced, which can prevent the conductive wires from breaking or loosening due to external tension or vibration; 3. Reduced electromagnetic interference: Twisted conductive wires can reduce electromagnetic interference to a certain extent and avoid inaccurate measurements caused by signal interference; 4. Prevent short circuits: If the conductive wires are scattered, collisions or contact short circuits are prone to occur. Twisting them into a bundle can reduce this risk; 5. Easy to connect: Twisted conductive wires are easier to ensure good contact and fixation with the electric energy meter.

[0005] At present, when the existing electric energy meter is connected to the cable, the worker needs to use pliers to twist the conductive wires at the end of the cable into a bundle, then insert the cable end into the electric energy meter, and finally use screws to tighten the conductive wires of the cable to fix them on the terminal of the electric energy meter. However, the electric energy meter usually needs to be connected to multiple cables. The connection process is time-consuming and labor-intensive, and it is not convenient for the electric energy meter and the cable to be quickly disassembled and assembled. Therefore, it does not meet the existing needs. In this regard, we propose an electric energy meter that is easy to separate and assemble. Summary of the invention

The clip 183 is used to The conductive wire 130 is clamped, and a bundle of conductive wires 130 is used in conjunction with two clips 183. The clips 183 are all configured as arc-shaped conductive sheets. The clips 183 are electrically connected to the electric energy meter body 110 through wires. The screw rod 170 is configured as a bidirectional screw. Two adjacent wire sleeves 182 are respectively threadedly connected to the reverse threads of the screw rod 170. A sliding piece can also be installed on the outside of the wire sleeve 182. The sliding piece is slidably inserted into the inside of the electric energy meter body 110 to prevent the wire sleeve 182 from rotating with the screw rod 170.

[0035] A bolt 184 is provided on the side of the electric energy meter body 110, and the number of the bolts 184 is set to two. A threaded groove 185 is opened on the side of the mounting plate 100 for use with the bolt 184. The bolt 184 and the threaded groove 185 are used together to fix the electric energy meter body 110 on the mounting plate 100, and the mounting plate is fixedly set on an electrical box or a wall.

[0036] In this embodiment: one hand moves the paddle 154 so that the paddle 154 slides into the sleeve 151 and the first spring 153 is compressed, and the other hand passes the end of the cable 120 through the sleeve 151 from bottom to top so that the conductive wire 130 is located above the housing 140, and then the paddle 154 is released so that the paddle 154 squeezes and clamps the cable 120 under the action of the rebound force of the first spring 153, thereby fixing the cable 120 in the middle of the housing; Subsequently, the slider 111 and the slide groove 112 are used in cooperation to make the electric energy meter body 110 slide down along the surface of the mounting plate 100, so that the conductive wire 130 is inserted into the inner side of the electric energy meter body 110 and is located between two adjacent clips 183. At the same time, the second gear 180 is engaged with the tooth groove 181 to drive the screw rod 170 to rotate, and then the screw rod 170 and the wire sleeve 182 are used in cooperation to make the wire sleeve 182 drive the clips 183 to approach each other, so as to clamp the upper end of the conductive wire 130, so that the conductive wire 130 is electrically connected to the electric energy meter body 110 through the clip 183. Finally, the electric energy meter body 110 is fixed to the mounting plate 100 by means of the bolts 184. Moreover, during this process, the first gear 160 rotates, and the first gear 160 is meshed with the gear ring 155, so that the sleeve 151 drives the cable 120 to rotate, and the conductive wire 130 is clamped and fixed by the clamping piece 183, so that the conductive wire 130 is twisted into a bundle. Through the above operation, the electric energy meter body 110 and the cable 120 can be quickly assembled; The bolt 184 is removed, and the electric energy meter body 110 is moved upward. The adjacent clips 183 are moved away from each other through the meshing of the second gear 180 and the tooth groove 181, and the clamping of the clip 183 on the conductive wire 130 is released, so that the electric energy meter body 110 and the cable 120 can be quickly separated. This solves the problem that when connecting the existing electric energy meter and the cable, workers need to use pliers to twist the conductive wires at the end of the cable into a bundle, then insert the cable end into the electric energy meter, and finally use screws to tighten and fix the conductive wires of the cable to the electric energy meter terminal. However, the electric energy meter usually needs to be connected to multiple cables, and the connection process is time-consuming and labor-intensive, which is not convenient for the electric energy meter and the cable to be quickly disassembled and assembled.

[0037] Embodiment 2: This embodiment is intended to solve the problem that it is inconvenient to drive the first gear 160 to rotate when installing the electric energy meter body 110, and it is difficult to twist the conductive wire 130 into a bundle, which easily affects the connection and assembly of the cable 120 and the electric energy meter body 110. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 A disc 190 is movably inserted in the threaded groove 185, and a second spring 191 is fixedly installed on the outside of the disc 190. The end of the second spring 191 is fixedly connected to the inner wall of the mounting plate 100, and a connecting rod 192 is fixedly installed on the lower side of the disc 190. A groove body connected to the threaded groove 185 is opened on the side of the mounting plate 100, and the width of the groove body is smaller than the diameter of the threaded groove 185, so that the coordinated use of the bolt 184 and the threaded groove 185 is not affected. The connecting rod 192 is slidably inserted in the groove body on the side of the mounting plate 100, and the lower end of the connecting rod 192 is arranged on the outside of the mounting plate 100.

[0038] A first wedge block 193 is fixedly installed at the bottom of the connecting rod 192, and a second wedge block 194 is arranged on the side of the first wedge block 193 for use therewith. A limiting rod 195 is fixedly installed on the outer side of the second wedge block 194. A groove body for use with the limiting rod 195 is opened on the side of the mounting plate 100. The end of the limiting rod 195 is slidably inserted in the groove body of the mounting plate 100, and the end of the limiting rod 195 is arranged in a square block shape, so that the limiting rod 195 can only slide up and down but cannot rotate, thereby limiting the first wedge block 193. The second wedge block 194 can only move up and down, and the bolt 184 is prevented from pushing the disc 190 so that the lower end of the connecting rod 192 is tilted outward, so that the second wedge block 194 can only move vertically up and down. A limit block 196 is fixedly installed on the inclined surface of the second wedge block 194, and a groove body used in conjunction with the limit block 196 is opened on the inclined surface of the first wedge block 193. The limit block 196 is slidably inserted in the groove body of the first wedge block 193 to prevent the first wedge block 193 from separating from the second wedge block 194.

[0039] A first rack 200 is arranged on the outside of the mounting plate 100, and a slide bar 2001 is installed on the side of the first rack 200 close to the mounting plate 100, and the end of the slide bar 2001 is slidably inserted in the side of the mounting plate 100, so that the first rack 200 is slidably arranged on the side of the mounting plate 100, and a first shaft rod 201 is rotatably inserted on the lower side of the shell 140 through a bearing, and a first gear 160 is fixedly installed on the top of the first shaft rod 201, and the first gear 160 is meshed with the gear ring 155, and a first bevel gear 202 is fixedly installed on the bottom of the first shaft rod 201, and a second shaft rod 203 is rotatably arranged on the outside of the mounting plate 100, and a second bevel gear 204 is fixedly installed on one end of the second shaft rod 203, and the second bevel gear 204 is meshed with the first bevel gear 202, and a third gear 205 is fixedly installed on the other end of the second shaft rod 203, and the third gear 205 is meshed with the first rack 200.

[0040] The diameter of the first gear 160 is greater than the diameter of the gear ring 155. Through the meshing of the first gear 160 and the gear ring 155, the gear ring 155 rotates more circles than the first gear 160, so that the gear ring 155 drives the cable 120 to rotate through the sleeve 151, so that the conductive wire 130 is twisted into a bundle. A driving assembly 210 is arranged between the second wedge block 194 and the first rack 200, and the driving assembly 210 is used to drive the first rack 200 to slide up and down.

[0041] It should be noted that when the electric energy meter body 110 is separated from the conductive wire 130 , it is not necessary to reversely twist the conductive wire 130 that has been twisted into a bundle, so the first gear 160 and the sleeve 151 remain stationary.

[0042] In this embodiment: when the bolt 184 is screwed into the thread groove 185, the disc 190 is pushed toward the inside of the mounting plate 100, so that the disc 190 drives the first wedge block 193 to move through the connecting rod 192, and the first wedge block 193 and the second wedge block 194 cooperate with each other, so that the second wedge block 194 drives the driving assembly 210 to move downward, so that the driving assembly 210 drives the first rack 200 to move downward, and the second bevel gear 204 is driven to rotate through the meshing of the first rack 200 and the third gear 205, and then the first bevel gear 202 is engaged with the second bevel gear 204 and the first bevel gear 202, so that the first bevel gear 202 drives the first gear 160 to rotate. Through the above operation, it is convenient to drive the first gear 160 to rotate when installing the electric energy meter body 110, and twist the conductive wire 130 into a bundle, so as to facilitate the connection and assembly of the cable 120 and the electric energy meter body 110.

[0043] Embodiment 3: This embodiment is intended to facilitate solving the problem that it is inconvenient to drive the first rack 200 to move downward. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The driving assembly 210 includes a slide plate 211 slidably mounted on the outside of the mounting plate 100 , a fourth gear 212 and a fifth gear 213 rotatably mounted on the outside of the slide plate 211 , and a second rack 214 fixedly mounted on the outside of the housing 140 .

[0044] The second wedge block 194 is located above the slide plate 211, and the second wedge block 194 intermittently contacts the slide plate 211. The fourth gear 212 and the fifth gear 213 are of the same size. The first rack 200 and the second rack 214 are respectively located on both sides of the slide plate 211, and one side of the fourth gear 212 and the fifth gear 213 are meshed with the first rack 200, and the other side of the fourth gear 212 and the fifth gear 213 are meshed with the second rack 214.

[0045] In this embodiment: the downward moving second wedge block 194 presses the slide plate 211 downward, so that the slide plate 211 drives the right sides of the fourth gear 212 and the fifth gear 213 to mesh with the second rack 214. At the same time, the left sides of the fourth gear 212 and the fifth gear 213 mesh with the first rack 200, so as to drive the first rack 200 to move downward, and make the downward moving distance of the first rack 200 the sum of the downward moving distance of the second wedge block 194 and the rotation circumference of the fourth gear 212, so that the downward moving distance of the first rack 200 is greater than the downward moving distance of the second wedge block 194. Therefore, this enlarged distance is transmitted to the third gear 205 through the first rack 200, increasing the number of rotations of the third gear 205, so that when the downward moving distance of the second wedge block 194 is short, the number of turns of the cable 120 is sufficient to twist the conductive wire 130 into a bundle.
