DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] For easier understanding, see Figures 1 to 19 The utility model provides an embodiment of a meter box for quickly replacing an electric energy meter without power outage, comprising a box body 1 and a box cover 2;

[0048] The box 1 is provided with an incoming main switch 3 and at least one electric energy meter plug socket, and the incoming main switch 3 is electrically connected to the electric energy meter plug socket;

[0049] An electric energy meter 5 is detachably mounted on the electric energy meter plug socket;

[0050] The electric energy meter plug socket includes a base 61, a wiring terminal, an insulating hinge seat 620, a conductive plug 623, a positioning plate 8, a first conductive plate 9 and a second conductive plate 10, and the wiring terminal includes a live wire input terminal 61A, a live wire lead-out terminal 61B, a neutral wire input terminal 61C and a neutral wire lead-out terminal 61D;

[0051] The live wire input terminal 61A, the live wire lead-out terminal 61B, the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D are sequentially installed side by side on the base 61. One end of the live wire input terminal 61A, the live wire lead-out terminal 61B, the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D are sequentially installed with an insulating hinge seat 620 and a U-shaped conductive seat 621. The U-shaped conductive seat 621 is electrically connected to the wiring terminal. The U-shaped conductive seat 621 is used in conjunction with a conductive plug 623. There are four conductive plugs 623, which are respectively connected to the live wire input terminal 61A, the live wire lead-out terminal 61B, The neutral line input terminal 61C corresponds to the neutral line lead-out terminal 61D. A through hole 81 for the conductive plug 623 to pass through is provided on the positioning plate 8. The rear end of the conductive plug 623 is hinged to the insulating hinge seat 620. The front end of the conductive plug 623 is used to be electrically connected to the electric energy meter 5. A middle hole 624 is provided in the conductive plug 623. The front end of the middle hole 624 is a conical hole. A movable top rod 625 is inserted into the middle hole 624. A plurality of slots communicating with the middle hole 624 are provided at the front end of the conductive plug 623. The plurality of slots form a multi-petal structure at the front end of the conductive plug 623.

[0052] The first conductive plate 9 and the second conductive plate 10 are installed on the side of the positioning plate 8, the first conductive plate 9 is arranged between the live wire input terminal 61A and the live wire lead-out terminal 61B, and the first conductive plate 9 is located below the live wire input terminal 61A and the live wire lead-out terminal 61B without contact when placed flat, the second conductive plate 10 is located between the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D, and the second conductive plate 10 is located below the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D without contact when placed flat, and the length of the first conductive plate 9 and the second conductive plate 10 is longer than the distance from the positioning plate 8 to the U-shaped conductive seat 621.

[0053] It should be noted that the main incoming switch 3 is electrically connected to the electric energy meter plug socket through the connection terminals of the electric energy meter plug socket, and there is at least one electric energy meter plug socket in the box 1. When the electric energy meter 5 is plugged into the electric energy meter plug socket, the electric energy meter 5 is electrically connected to the user's power switch 4, and the user's power switch 4 is then electrically connected to the user's electrical appliances through wires. The electric energy meter plug socket includes a base 61, four connection terminals installed side by side on the base 61, and the four connection terminals include a live wire input terminal 61A, a live wire lead-out terminal 61B, a neutral wire input terminal 61C, and a neutral wire lead-out terminal 61D. An insulating hinge seat 620 and a U-shaped conductive seat 621 are installed in sequence at one end of the four connecting terminals. After the rotating shaft 622 is inserted into the insulating hinge seat 620, it is hinged with the U-shaped groove of the conductive plug 623. The conductive plug 623 can be electrically connected to or separated from the U-shaped conductive seat 621 by rotation. A middle hole 624 is provided in the conductive plug 623. The front end of the middle hole 624 is a conical hole. A movable push rod 625 is inserted in the middle hole 624. When the push rod 625 presses against the inner wall of the conical hole, the diameter of the front end of the conductive plug 623 can be increased. A plurality of slots connected to the middle hole 624 are provided at the front end of the conductive plug 623. The plurality of slots form a plurality of expansion petals 626 at the front end of the conductive plug 623 to form a multi-petal structure.

[0054] A positioning plate 8 is horizontally connected between each conductive plug 623 to ensure that each conductive plug 623 can maintain consistent movement when rotating. A first conductive plate 9 and a second conductive plate 10 are installed on one side of the positioning plate 8. Both are rectangular metal plates. When the electric energy meter 5 is plugged into the four conductive plugs 623 on the electric energy meter plug socket, the first conductive plate 9 is located below and without contact between the live wire input terminal 61A and the live wire lead-out terminal 61B, and the second conductive plate 10 is located between the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D, and the live wire input terminal 61A and the live wire lead-out terminal 61B are connected through the electric energy meter 5, and the neutral wire input terminal 61C and the neutral wire lead-out terminal 61D are connected through the electric energy meter 5. When the electric energy meter 5 is rotated 90 degrees (or lifted), the electric energy meter 5 drives the positioning plate 8 and the four conductive plugs 623 to rotate synchronously, and finally the electric energy meter 5 is not in contact with the four conductive plugs 623 on the electric energy meter plug socket. During the above rotation process, the first conductive plate 9 and the second conductive plate 10 also rotate synchronously with the positioning plate 8, and finally the first conductive plate 9 electrically connects the live wire input terminal 61A with the live wire lead-out terminal 61B, and the second conductive plate 10 electrically connects the neutral wire input terminal 61C with the neutral wire lead-out terminal 61D. At this time, unplugging and replacing the electric energy meter 5 can also supply power to the user, but the electricity used by the user at this time is not counted in the electric energy meter 5. However, because the replacement of the electric energy meter 5 can be completed in about a few seconds, the above-mentioned uncounted electricity is very small.

[0055] The utility model provides a meter box for quickly replacing an electric energy meter without power outage. An electric energy meter plug-in socket is arranged in the box body 1. The electric energy meter 5 can be directly plugged and installed on the electric energy meter plug-in socket through the wiring terminals on the electric energy meter plug-in socket. The insulating hinge seat 620 on the electric energy meter plug-in socket can realize 90-degree rotation of the electric energy meter 5 under the cooperation of the conductive plug tube 623 and the positioning plate 8. When the electric energy meter 5 is connected, the first conductive plate 9 and the second conductive plate 10 do not contact the wiring terminals. The wiring terminals are connected by the electric energy meter. The meter 5 is turned on. When the energy meter 5 is rotated 90 degrees, the energy meter 5 drives the positioning plate 8 and the conductive plug 623 to rotate synchronously, so that the energy meter 5 is not in contact with the conductive plug 623 on the energy meter plug socket, and the first conductive plate 9 and the second conductive plate 10 are connected to the wiring terminal, so that when the energy meter 5 is pulled out and replaced, power can still be supplied to the user, which solves the technical problems that the replacement process of the energy meter 5 in the existing energy meter box will cause power outage for the user, and the installation and disassembly process is cumbersome and inefficient.

[0056] In one embodiment, the insulating hinge seat 620 includes a rectangular plate body and a rotating shaft 622. The top of the rectangular plate body is an arc surface 627. A rotating shaft 622 through hole 81 is set on the rectangular plate body. The rotating shaft 622 passes through the rotating shaft 622 through hole 81. The distance from the arc surface 627 of the rectangular plate body to the rotating shaft 622 is smaller than the distance from the side of the rectangular plate body to the axis of the rotating shaft 622.

[0057] It should be noted that the insulating hinge seat 620 includes a rectangular plate body and a rotating shaft 622. The top of the rectangular plate body is an arc surface 627. The distance from the arc surface 627 to the rotating shaft 622 is smaller than the distance from the side to the axis of the rotating shaft 622. Therefore, when the conductive plug 623 rotates to the side of the insulating hinge seat 620, the top rod 625 is squeezed by the side of the insulating hinge seat 620 and moves forward in the middle hole 624 of the conductive plug 623. When moving forward, the expansion petal 626 at the front end of the conductive plug 623 expands outward, thereby achieving a close electrical connection with the four plug holes on the electric energy meter 5, completing the installation of the electric energy meter 5 and the electric energy meter plug socket. When the conductive plug 623 rotates to the arc surface 627, the pressure on the push rod 625 gradually decreases until it disappears, so the push rod 625 automatically moves backward in the middle hole 624 of the conductive plug 623. When moving backward, the expansion petal 626 at the front end of the conductive plug 623 retracts inward and automatically resets, thereby achieving power-off separation from the four plug holes on the electric energy meter 5. At this time, the electric energy meter 5 can be unplugged and replaced.

[0058] In one embodiment, the electric energy meter plug-in socket also includes a locking device 7, which is located on the outside of the outermost terminal. The locking device 7 includes a lower fixed seat 70, a sliding seat 71, a pressing column 72, a first spring 73, a second spring 74 and a clamping rod 75. The lower fixed seat 70 is installed on the base 61, and the sliding seat 71 is movably installed on the top of the lower fixed seat 70. The lower fixed seat 70 is hollow inside, and the top of the lower fixed seat 70 is provided with a first through groove connected to the inside of the lower fixed seat 70. The sliding seat 71 is provided with a second through groove running through the upper and lower parts, and the second through groove corresponds to the first through groove. The pressing column 72 passes through the second through groove and the first through groove and extends into the lower fixed seat 70. One end of the first spring 73 is fixed to the bottom of the lower fixed seat 70. The first spring The other end of the spring 73 is connected to a pressing column 72 extending into the interior of the lower fixed seat 70. The side surface of the pressing column 72 away from the first spring 73 is provided with a first conical surface, and the side of the second through groove that contacts the first conical surface is provided with a second conical surface. The second conical surface is used in pairs with the first conical surface. The end of the pressing column 72 connected to the first spring 73 is provided with a locking block. The length of the locking block is greater than the first through groove. The sliding seat 71 is provided with a third through groove running through the left and right. The third through groove is staggered with the second through groove. The clamping rod 75 runs through the third through groove. One end of the clamping rod 75 is aligned with the clamping hole 82 provided on the positioning plate 8. The other end of the clamping rod 75 is connected to one end of the second spring 74. The other end of the second spring 74 is fixed to the plug-in column 610 provided on the base 61.

[0059] It should be noted that in order to prevent the electric energy meter 5 from being loosened when the electric energy meter 5 is installed on the electric energy meter plug socket, a locking device 7 is installed on the outer side of the outermost terminal, and the locking device 7 includes a lower fixed seat 70 fixed on the base 61, a sliding seat 71 installed on the top of the lower fixed seat 70, and a pressing column 72 inserted into the sliding seat 71 and the lower fixed seat 70 in sequence, the upper end of the pressing column 72 extends out of the upper end surface of the base 61, and the lower end of the pressing column 72 is sleeved with a first spring 73, and the other end of the first spring 73 is against the lower end inner wall of the lower fixed seat 70, and a positioning block is provided between the interior of the lower fixed seat 70 and the first through groove, and the positioning block is used to limit the pressing column 72 to prevent the pressing column 72 from popping out. A second spring 74 is sleeved on one side of the sliding seat 71, and the other end of the second spring 74 is sleeved horizontally on the plug-in column 610 on the base 61. A clamping rod 75 is horizontally arranged on the other side of the sliding seat 71, and a clamping hole 82 is correspondingly opened on the positioning plate 8. The side of the pressing column 72 away from the first spring 73 is provided with a first cone surface, and the side of the second through groove that contacts the first cone surface is provided with a second cone surface. The second cone surface is used in pairs with the first cone surface. When the pressing column 72 is pressed down, the sliding seat 71 moves horizontally due to the guidance of the first cone surface and the second cone surface, and the first spring 73 and the second spring 74 play the role of automatic reset. When the clamping rod 75 enters the clamping hole 82, the positioning plate 8 is locked and cannot rotate, otherwise it is unlocked. In order to prevent the electric energy meter 5 from loosening, there are two locking devices 7, which are respectively located on the outside of the two outermost terminals on the left and right.

[0060] In one embodiment, the electric energy meter plug socket also includes a conductive plug insulating sleeve assembly 11. A cavity for accommodating the conductive plug insulating sleeve assembly 11 is provided on the base 61 at the installation position of the electric energy meter 5. The conductive plug insulating sleeve assembly 11 includes an insulating sleeve 110 and a hinge 111. The insulating sleeve 110 is paired with the conductive plug 623. The hinge 111 has two pieces. One ends of the two hinges 111 are respectively installed on the inner walls on both sides of the cavity, and the other ends of the two hinges 111 are respectively connected to the insulating sleeve 110.

[0061] It should be noted that in order to prevent the human body from contacting the four conductive plugs 623, prevent electric shock, and extend the service life of the four conductive plugs 623. A conductive plug insulating sleeve assembly 11 is hinged on the base 61, which includes four insulating sleeves 110 and two hinges 111. One end of the two hinges 111 is hinged on the inner walls on both sides of the cavity of the base 61, and the other end of the two hinges 111 is hinged to the two insulating sleeves 110 on the outside. When the four conductive plugs 623 of the electric energy meter plug socket are plugged with an electric energy meter 5, the conductive plug insulating sleeve assembly 11 is rotated and stored in the cavity of the base 61. When the electric energy meter 5 is not plugged in, the conductive plug insulating sleeve assembly 11 is rotated to correspondingly sleeve the four insulating sleeves 110 on the four conductive plugs 623.

[0062] In one embodiment, the electric energy meter plug socket further includes an insulating gland 63, which is installed on the electric energy meter plug socket.
