DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figure 1-9 As shown, an electric meter without power supply change includes a meter body 10, wherein the lower end of the meter body 10 is provided with an extrusion arc 20 electrically connected to the inside, the extrusion arc 20 is of multi-piece design, the outer side of the extrusion arc 20 is provided with a groove, the outer side of the extrusion arc 20 is further provided with a fastening ring 21 that can correspond to the groove, the thickness of the extrusion arc 20 gradually increases from bottom to top, the extrusion arc 20 can extend into the middle conductor 11, the middle part of the middle conductor 11 is fixedly connected to the insulator 12, the upper half of the insulator 12 can be inserted into the lower end of the meter body 10, and the lower half can be inserted into the upper end of the fixed base 13, and the lower end of the middle conductor 11 can extend into the switching sheet 16, the switching piece 16 is fixedly connected to the switching shaft 17, and the switching shaft 17 is rotatably connected to the left and right side walls on the upper side of the fixed base 13. The lower side of the fixed base 13 is evenly provided with wires for extending into the wiring cavity 32, and the wiring cavity 32 is provided with a wiring harness electrically connected to the switching piece 16 via the switching shaft 17. An insulating plate 15 can be placed on the front side of the wiring cavity 32, and a disassembly cover 14 that can completely cover it is also provided on the front side of the fixed base 13; a soft wire processing device S1 is provided in the wiring cavity 32, which can perform wire harness processing while maintaining power supply when the wire is a soft wire composed of wire harness wires.

[0022] The soft wire processing device S1 includes an operating sheet 25, on which a connecting rod 24 is fixedly connected, and the upper end of the connecting rod 24 is fixedly connected to a slide bar 27, and the slide bar 27 is slidably connected to the bottom wall of the top sheet 22, and the outer end of the top sheet 22 is fixedly connected to a lug 23, and the lug 23 can cooperate with the slideway provided inside the wiring cavity 32, and a screw sleeve 28 is also slidably connected on the lower end surface of the slide bar 27, and a screw rod 31 is threadedly connected in the screw sleeve 28, and a gear 30 is fixedly connected to the outer end of the screw 31, and the gear 30 is meshed with the lower end surface of the top sheet 22, and a wire reeling fork 29 is fixedly connected to the inner end of the screw sleeve 28; when it is necessary to complete the continuous top and reorganize the wires of the soft wire, the wire harness can be placed from the notch of the soft wire processing device S1 to the center, and then the top sheet 22 is placed from the lower end of the wiring cavity 32. Since the lug 23 can engage with the wiring cavity 32, The top plate 22 will not rotate due to the cooperation of the internal slideway. Then, the connecting rod 24 drives the slide bar 27 to rotate by rotating the operating piece 25. The rotation of the slide bar 27 drives the screw sleeve 28 and the components inside it to move relative to the top plate 22. Since the gear 30 is engaged with the lower end surface of the top plate 22, the gear 30 will rotate at this time. The rotation of the gear 30 drives the screw sleeve 28 to rotate while driving the wire-straightening fork 29 to extend inward, thereby extending into the wiring harness wire. Then, the operating piece 25 is pushed to drive the components thereon to move upward as a whole, thereby straightening the wiring harness wire. When the top plate 22 moves out of the wiring cavity 32, the entire device is rotated to screw the straightened wiring harness together again. During the whole process, part of the device is in the wiring cavity 32, and the wire-straightening fork 29 is in contact with the wiring harness, so that power outage will not occur.

[0023] The insulating plate 15 is provided with threaded holes 19 into which screws can be screwed, so that the wiring harness can be pressed onto the wiring cavity 32 by means of the screws.

[0024] The insulating plate 15 is also provided with fixing holes 18 for fixing the insulating plate 15 on the fixing base 13 .

[0025] The front opening of the watch body 10 can be covered by a cover plate.

[0026] Working process: Initially, the wiring harness extends into the wiring cavity 32 through the lower end of the fixed base 13, and is pressed by the insulating plate 15 and the screws. When the meter needs to be replaced, the disassembly cover 14 is removed, and the screws and other parts fixing the meter body 10 are removed, and then the meter body 10 is rotated. The rotation of the meter body 10 will be centered on the switching shaft 17, and the rotation is completed under the transition of the intermediate conductor 11 and the insulator 12. The insulator 12 and the intermediate conductor 11 are taken out and inserted from top to bottom into the switching piece 16 at another angle coaxial with the switching shaft 17. At this time, the new and old meters are connected in parallel, and there will be no power failure. The old meter is then unplugged from the switching piece 16, and the new meter is adjusted to the optimal position and turned back to the working position. It is worth mentioning that after the upper end of the intermediate conductor 11 is extended into the extrusion arc 20, different fixing forces can be achieved by adjusting the position of the fastening ring 21, so that the intermediate conductor 11 can be fixed without damaging it, thereby ensuring that the intermediate conductor 11 and the insulator 12 can be recycled, and then the disassembly cover 14 and the cover plate of the meter body 10 can be covered. Replacing the meter does not require changing the fixed base 13, which greatly reduces the risk of false connection caused by rewiring when replacing the meter.

Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
