[0028] Example 1

[0029] This embodiment provides a connector for installing an electric meter, such as Figure 1 As shown, it includes an electric meter body 1, and a slider 2 is fixedly installed on the back of the electric meter body 1;

[0030] like Figure 2-4 As shown, the plug-in assembly 3 includes an electromagnet 31, an electric wire 33, a lever and an insert block 37. The electromagnet 31 is fixedly mounted on the back of the slider 2. The electromagnet 31 is electrically connected to the electric wire 33 through a terminal 32. The electromagnet 31 includes an iron core and a winding wire. The two ends of the winding wire on the electromagnet 31 are electrically connected to the electric wire 33 and the meter body 1 respectively.

[0031] like Figure 4 As shown, the back of the slider 2 is slidably connected to the plug block 37, the end of the lever is in contact with the plug block 37, and a limit assembly 4 is provided on the side of the slider 2. The limit assembly 4 includes a sliding bracket 41 and a limit plate 44. The limit plate 44 is provided on the side of the sliding bracket 41 facing the plug block 37. The sliding bracket 41 is fixedly installed on a wall or a box. A plurality of limit plates 44 are provided and are evenly distributed along a straight line on the sliding bracket 41. The plug block 37 is inserted into the limit plate 44 to fix the position of the plug block 37 and the slider 2, thereby fixing the position of the meter body 1.

[0032] When the meter body 1 is powered on, that is, when the wire 33 connected to the meter body 1 is powered on, the electromagnet 31 is powered on because it is connected to the wire 33. At this time, the electromagnet 31 generates magnetic force, which attracts the lever through the magnetic force, so that the lever lifts the insert block 37 and inserts it into the limit plate 44.

[0033] When replacing the meter body 1, in order to protect human safety, it is necessary to first cut off the power to the meter body 1, that is, turn off all circuits connected to the meter body 1. By taking advantage of the fact that the power needs to be cut off when replacing the meter body 1, no current passes through the electromagnet 31, and the plug block 37 moves downward under the action of its gravity to separate from the limit plate 44, so that the slider 2 can be removed from the limit assembly 4.

[0034] like Figure 3 As shown, the slider 2 adopts a convex structure, two plug-in blocks 37 are provided, symmetrically about the center line of the slider 2, and an extended magnetic conductive plate 34 is fixedly installed on the top of the electromagnet 31. The extended magnetic conductive plate 34 runs through the raised part in the middle of the slider 2, and the extended magnetic conductive plate 34 is located directly below the plug-in block 37. The two ends of the extended magnetic conductive plate 34 are respectively located on both sides of the raised part of the slider 2, so that the plug-in blocks 37 on both sides of the raised part of the slider 2 can be affected by magnetic force, and the two plug-in blocks 37 are inserted into the limit plate 44, so that the position of the slider 2, that is, the position of the meter body 1, is more stable.

[0035] The lever is divided into two parts, left and right, by the shaft. The part of the lever close to the center line of the slider 2 is made of a plastic plate 35, and the part of the lever away from the center line is made of an iron sheet 36. The top of the plastic plate 35 is in contact with the plug 37. This prevents both the left and right parts of the lever from being affected by magnetic force and being unable to lift the plug 37.

[0036] In this embodiment, during installation, the meter body 1 is not powered on, and the plug block 37 is moved away from the limit plate 44 under the action of gravity. At this time, the meter body 1 is installed on the limit assembly 4. After the installation is completed, the meter body 1 is powered on. At this time, there is current on the electromagnet 31, and the lever is attracted by the electromagnet 31. The lever lifts the plug block 37 and inserts it into the limit plate 44 to fix the position of the meter body 1; when disassembling, the meter body 1 is powered off, and the plug block 37 is moved away from the limit plate 44 under the action of gravity, so that the meter body 1 can be disassembled.

[0037] Example 2

[0038] Based on the first embodiment, this embodiment provides a connector for installing an electric meter, such as Figure 2 As shown, the sliding bracket 41 adopts a square frame structure, and a slide groove 42 is provided in the middle of the sliding bracket 41, and the slider 2 slides in the slide groove 42. Even if the meter body 1 fails and the power is suddenly cut off, the meter body 1 will not fall because the slider 2 is in the slide groove 42. When the meter body 1 is installed in the meter box, since other electrical components are also installed in the meter box, the volume of the meter body 1 blocks the installation or maintenance of other electrical components, and the slider 2 slides on the slide groove 42 to make way for the maintenance of other electrical components.

[0039] like Figure 2 As shown, a slot 43 is provided at the top of the sliding bracket 41 and near the corner, and the width of the slot 43 is the same as the raised portion of the slider 2. The slider 2 is placed from the slot 43 and then enters the frame of the sliding bracket 41 to slide.

[0040] In this embodiment, when repairing other electrical components, the position of the meter body 1 can be changed by sliding the slider 2, so that the meter body 1 can make way for maintenance personnel to repair other electrical components. The meter body 1 does not need to be completely disassembled and can be placed on the ground alone to avoid static electricity on the meter body 1 absorbing dust on the ground.

[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
