[0018] 1. The present invention provides a wiring assembly. When wiring, the wire can be inserted into the wiring hole by pressing and releasing the extrusion block to complete the quick wiring work, and the clamping force of the pair can be adjusted synchronously by adjusting the elastic coefficient of the first elastic member, thereby avoiding problems such as poor contact, looseness and breaking of the copper wire caused by excessive or insufficient force, so that the power output is stable and the accuracy of the electric energy meter is improved;
[0019] 2. The present invention adopts a split type setting through the setting of the installation component. On the one hand, the electrical connection device can be quickly separated from the main body of the electric energy meter for installation, which is convenient to disassemble, and can be disconnected from the main body of the electric energy meter during the installation process, making the later live wiring and maintenance work more convenient and safe. On the other hand, only after the wedge-shaped slider is inserted into the first limiting groove to limit the installation block, the wire can be connected with the main body of the electric energy meter, preventing poor contact caused by improper installation during the live installation process, causing short circuit, circuit damage and arcing, etc., thereby improving the safety of the electric energy meter;
[0020] 3. The present invention uses the first sealing airbag and the second sealing airbag to seal the split groove through the setting of the detection component, which can play a role in moisture and dust prevention, and uses the gas stored in the gas storage chamber to detect the insulation layer of the wire, and remotely alarms the aging of the insulation layer, reminding maintenance personnel to replace the wires with aging insulation layers in time, preventing leakage and increased power consumption caused by aging insulation, and at the same time, avoiding heating and spontaneous combustion caused by aging insulation layers, thereby further improving the service life and safety of the electric energy meter;

A transition slot 223 is provided inside the mounting block 211. The transition slot 223 divides each transmission conductor 213 into two sections. A telescopic slot 224 connected to the transition slot 223 is provided on the side of the mounting block 211 close to the display screen 12. A first limiting slot 15 corresponding to the position of the telescopic slot 224 is provided on the side of the electric energy meter body 1 close to the display screen 12. A limiting block 16 is slidably connected in the first limiting slot 15. The limiting block 16 is made of insulating material. The wedge slider 222 is slidably connected in the telescopic slot 224. The transition slider 221 is slidably connected in the transition slot 223. The transition slider 221 is installed with transition conductors 225 of the same number and corresponding position as the transmission conductors 213. The transition slider 221 is away from the wedge slider 222. A plurality of second elastic members 226 are connected between the side and the transition slide groove 223, a sealing groove 227 is provided on the side of the wedge-shaped slider 222 close to the transition slider 221, a sealing block 228 is fixedly connected to the side of the transition slider 221 close to the wedge-shaped slider 222 and is sealingly and slidably connected to the sealing groove 227, a thermal expansion material is filled between the sealing block 228 and the sealing groove 227, the temperature of the terminal when the electric energy meter is working normally generally does not exceed 50 degrees Celsius, the thermal expansion material can be selected from a liquid with a boiling point above 50 degrees Celsius, such as water, which is liquid under normal conditions and will vaporize and expand under high temperature conditions, a placement groove 229 is provided on the side of the mounting block 211 close to the split groove 11, a fourth elastic member 230 is sleeved in the placement groove 229, one end of the fourth elastic member 230 is connected to the inner wall of the placement groove 229, and the other end of the fourth elastic member 230 is connected to the inner wall of the split groove 11.
[0039] In actual use, Figure 1 As shown, when the electrical connection device 2 is used for the first time for wiring, it is inserted into the split groove 11. First, by pressing the limit block 16, the limit block 16 slides in the first limit groove 15, and the wedge-shaped slider 222 is pushed out from the first limit groove 15. At this time, the mounting block 211 loses its limit position, as shown in FIG. Figure 2 As shown, the mounting block 211 will slide out of the split groove 11 under the rebound effect of the fourth elastic member 230;
[0040] When wiring, press the extrusion block 216 corresponding to the wiring hole 212, so that the extrusion block 216 compresses the corresponding first elastic member 217 and slides out from the corresponding wiring hole 212. At this time, insert the wire into the corresponding wiring hole 212. After it is fully inserted, release the extrusion block 216. At this time, the extrusion block 216 will squeeze and clamp the wire core in the wiring hole 212 under the rebound action of the corresponding first elastic member 217, thereby completing the rapid wiring work. The clamping force of the wire core can be synchronously adjusted by adjusting the elastic coefficient of the first elastic member 217, and the first elastic member 217 can be selected according to actual conditions;
[0041] After all wiring work is completed, the installation block 211 is inserted back into the split groove 11. During the sliding process of the installation block 211 inside the split groove 11, the inner wall of the split groove 11 will contact the wedge surface of the wedge-shaped slider 222, thereby pushing the wedge-shaped slider 222 to drive the transition slider 221 and the transition conductor 225 to slide in the transition groove 223, and compress the second elastic member 226, so that the transition conductor 225 is separated from the transmission conductor 213 and disconnected. When the installation block 211 is fully inserted into the split groove 11, the electrical connection conductor 14 will contact and conduct with the transmission conductor 213. At the same time, the telescopic groove 224 will be connected to the first limiting groove 15. The transition slider 221 and the wedge slider 222 will move in the direction of the first limiting groove 15 in the transition groove 223 and the telescopic groove 224 under the rebound action of the second elastic member 226, thereby returning to the initial position and wedge The wedge-shaped slider 222 is inserted into the first limiting groove 15 to limit the mounting block 211. After the wedge-shaped slider 222 is inserted into the first limiting groove 15, the limiting block 16 will be pushed out of the first limiting groove 15 and extend out of the surface of the electric energy meter body 1, which is convenient for the next wiring work. At the same time, after the transition slider 221 returns to the initial position, the transition conductor 225 will contact and conduct with the transmission conductor 213. Only after the wedge-shaped slider 222 is inserted into the first limiting groove 15 to limit the mounting block 211, the wire can be connected with the electric energy meter body 1, preventing poor contact caused by improper installation during the live installation process, causing short circuits, circuit damage, arcing and other problems. At this time, the wire will form an electrical connection with the electronic components in the electric energy meter body 1 through the transmission conductor 213, the transition conductor 225 and the electrical connection conductor 14, thereby quickly completing the installation of the electrical connection device 2;
[0042] When the electric energy meter is wired incorrectly or an abnormality occurs inside the electric energy meter, the circuit inside the electric energy meter will be subjected to abnormal current, causing the temperature to rise rapidly. At this time, the temperature will be transmitted to the transition slider 221 and the sealing block 228 through the transition conductor 225. After the temperature of the sealing block 228 rises, the thermal expansion material in the sealing groove 227 will expand rapidly. Since the limit block 16 cannot continue to move outward under the limiting action of the first limit groove 15, the wedge-shaped slider 222 cannot push the limit block 16 to move after the thermal expansion material expands. The expanded thermal expansion material will push the sealing block 228 and the transition slider 221 to drive the transition conductor 225 to move away from the wedge slider 222, so that the transition conductor 225 loses contact with the transmission conductor 213, and the wires cannot form an electrical connection with the electronic components in the electric energy meter body 1, thereby completing the power-off protection. The maintenance personnel can learn about the abnormal situation through power-off, thereby completing the detection of circuit abnormalities, which is convenient for the maintenance personnel to perform repairs.
[0043] To sum up, through the setting of the wiring assembly 21, when wiring, the wire can be inserted into the wiring hole 212 by pressing and releasing the extrusion block 216 to complete the quick wiring work, and the clamping force can be synchronously adjusted by adjusting the elastic coefficient of the first elastic member 217, thereby avoiding problems such as poor contact, looseness and breaking of the copper wire caused by excessive or insufficient force, so as to stabilize the power output and improve the accuracy of the electric energy meter.
[0044] Through the setting of the installation component 22, on the one hand, a split setting is adopted, so that the electrical connection device 2 can be quickly separated from the electric energy meter body 1 for installation, and disassembly is convenient, and the power can be disconnected from the inside of the electric energy meter body 1 during the installation process, making the subsequent live wiring and maintenance work more convenient and safer. On the other hand, only after the wedge-shaped slider 222 is inserted into the first limiting groove 15 to limit the mounting block 211, the wires can be connected to the electric energy meter body 1, preventing poor contact caused by improper installation during the live installation process, causing short circuits, circuit damage, arcing and other problems, thereby improving the safety of the electric energy meter. Embodiment 2
[0045] After long-term use, the insulation layer of the wire will gradually age and need to be inspected regularly. If it is not inspected and replaced in time, it is easy to spontaneously combust and cause a fire. Therefore, this embodiment improves the device described in the above embodiment.

The one-way valve 241 is used for exhausting gas. By adjusting the elastic coefficient of the elastic member inside the second one-way valve 241, the second one-way valve 241 plays the role of air pressure control. The inner wall of the air storage chamber 235 is provided with a first detection contact piece 242. One side of the piston plate 236 is provided with a second detection contact piece 243 corresponding to the position of the first detection contact piece 242. When the first detection contact piece 242 contacts the second detection contact piece 243, it can be connected to form an electrical signal. A rotating groove 244 is opened inside the mounting block 211. A rotating rod 245 is rotatably connected in the rotating groove 244. Both ends of the rotating rod 245 are fixedly connected with gears 246. The split groove 11 There are two racks 247 meshing with the gear 246 fixedly connected inside. When the mounting block 211 is fully inserted into the split groove 11, the gear 246 and the rack 247 are out of meshing state. A winding groove 248 is opened inside the mounting block 211.

After the first sealed airbag 231 can no longer expand, the gas will enter the interior of each second sealed airbag 232, so that Each second sealing airbag 232 expands and wraps the insulating layer of the wire, thereby sealing each wiring hole 212, further fixing the wire to prevent the wire from falling off and loosening. After the first sealing airbag 231 and the second sealing airbag 232 cannot continue to expand, the gas stored in the gas storage chamber 235 will be discharged into the pressing groove 214 through the gas outlet 240 and the second one-way valve 241. By adjusting the elastic coefficient of the elastic member inside the second one-way valve 241, the exhaust pressure of the second one-way valve 241 is adjusted. Since the pressing groove 214 is located inside the split groove 11 at this time, the discharged gas will be connected to the split groove 11.
[0049] When the insulation layer of the wire is in a normal state, the gas discharged into the split groove 11 cannot be discharged under the action of the first sealing airbag 231 and the second sealing airbag 232. When the insulation layer of the wire is aged, the insulation layer will be deformed, have gaps and damage, which will cause the sealing effect of the second sealing airbag 232 to decrease. The gas discharged into the split groove 11 will gradually be discharged from the wiring hole 212, further causing the piston plate 236 to move in the direction of the air inlet 237 in the air storage chamber 235. During the movement of the piston plate 236, the piston plate 236 will drive the second detection contact piece 243 to contact and conduct with the first detection contact piece 242, thereby forming an electrical signal and performing a remote alarm, thereby reminding the maintenance personnel that the insulation needs to be replaced due to aging. The degree of insulation aging can be synchronously adjusted by adjusting the installation position of the first detection contact piece 242.
[0050] To sum up, by setting up the detection component 23, the split slot 11 is sealed by using the first sealing airbag 231 and the second sealing airbag 232, which can play a role in moisture-proof and dust-proof. The gas stored in the gas storage chamber 235 is used to detect the insulation layer of the wire, and a remote alarm is issued for the aging of the insulation layer, reminding maintenance personnel to replace the wires with aged insulation layers in time to prevent leakage and increased power consumption due to aging of the insulation. At the same time, it also avoids the heat and spontaneous combustion that may be caused by the aging of the insulation layer, thereby further improving the service life and safety of the electric energy meter.
