Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment, and in particular to a simple device for quickly replacing an electric energy meter without power outage. Background Art

[0002] The connectors of existing single-phase electricity meters for residential users are mostly metal copper columns. A jack for wiring is provided at the rear of the electricity meter. A gap-type connector that is tightened manually with screws or an interference-type connector that is directly inserted and pulled out without tightening the screws is used to make it firmly contact with the jack to achieve high current conduction capacity. Since the installation locations of residential electricity meters are all in relatively narrow spaces, each time the electricity meter is replaced or repaired, the screws must be tightened manually or the insertion and removal operations must be performed vigorously. The operation is inconvenient and inefficient, and there are metal conductors exposed, which poses a safety hazard and a loophole for electricity theft. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a simple device for quickly replacing an electric energy meter without power outage, and the present invention is implemented through the following technical solutions.

[0004] A simple device for quickly replacing an electric energy meter without power outage comprises an insulating base, an insulating fixing seat, an insulating rotating cover, an insulating cover plate, a copper pin connector, a locking bolt pin and a metal spring;

[0005] The insulating base is an integrally formed injection molded part, and the insulating base comprises a back plate, ear plates symmetrically arranged below the front side of the back plate, and a support plate fixed to the bottom of the front side of the back plate;

[0006] The insulating fixing seat is connected to the support plate by a buckle, and the insulating fixing seat is also fixed to the insulating base by a slide groove, and the upper rear side of the insulating fixing seat is arc-shaped;

[0007] The insulating rotating cover is buckled on the insulating fixed seat, the inner walls of the front and rear side plates of the insulating rotating cover are rotatably connected to the insulating fixed seat through a rotating head, and an arc-shaped cover plate is provided at the lower rear side of the insulating rotating cover;

[0008] The insulating cover plate is rotatably connected to the long hole arranged on the front side of the insulating rotating cover through a rotating shaft;

[0009] The copper pin connector and the bolt pin are both cylindrical cavity structures, the front end of the copper pin connector is in a four-petal cylindrical shape, and the rear end is in a door-shaped structure, the copper pin connector is fixedly connected to the top plate of the insulating rotating cover and a plurality of the copper pin connectors are evenly arranged along the length direction of the insulating rotating cover, the bolt pin is made of metal, the front end of the bolt pin is in a lantern shape, and the rear end is in a cylindrical shape, and the top end of the bolt pin is aligned and plugged into the inner cavity of the copper pin connector;

[0010] The metal spring is fixed in the insulating fixing seat and is arranged corresponding to the lock tongue pin. The head of the metal spring extends out of the insulating fixing seat. When the insulating rotating cover is in the vertical state, the metal spring is inserted into the door-type structure of the corresponding copper pin connector and squeezes the lock tongue pin. When the insulating rotating cover is rotated out, the metal spring is pulled out of the door-type structure of the corresponding copper pin connector and the squeezing of the lock tongue pin is cancelled.

[0011] Furthermore, the upper parts of the copper needle connector and the lock tongue needle are provided with slots. Through the setting of the slots, when subjected to external compression, the upper part of the copper needle connector forms petal-shaped fins and the upper part of the lock tongue needle can form lantern-shaped fins. Each of the lock tongue needles corresponds to a group of metal spring leaves, and each group of metal spring leaves has a tendency to expand outward.

[0012] Furthermore, a metal terminal is fixedly connected inside the insulating fixing seat, and the metal terminal is sleeved on the outside of each group of the metal spring sheets.

[0013] Furthermore, a metal shorting piece corresponding to each group of the metal spring pieces is fixedly connected to the rear side of the insulating rotating cover.

[0014] Furthermore, the integral structure of the insulating rotating cover and the insulating cover plate is symmetrically fixed with limit axes on both sides, and the ear plate is provided with a limit groove corresponding to the limit axis, and the limit groove includes a vertical positioning portion and a sliding portion with an inclined bottom surface.

[0015] Furthermore, a space-avoiding groove is provided on the back plate.

[0016] Furthermore, the insulating base, the insulating fixing seat, the insulating rotating cover and the insulating cover plate are all made of hard plastic injection molding.

[0017] The invention has a compact structure, occupies a small volume, is easy and quick to install and has the following specific advantages:

[0018] 1. The device is connected to the socket at the tail of the electric energy meter through a copper pin connector. The expansion of the lock tongue pin forces the fins of the copper pin connector to make firm contact with the socket of the electric energy meter to achieve high current conduction capacity. The entire meter replacement process does not require screwing, and the time is shortened from the original 5 minutes to 10 seconds, which is convenient and quick.

[0019] 2. The device has a built-in metal short-circuit, which can be short-circuited by rotating the electric energy meter, so that the electric energy meter can be replaced without auxiliary tools without power outage.

[0020] 3. The device is cleverly designed to embed all metal conductors inside the insulating shell. No conductors are exposed during the entire meter replacement process, which is safe and reliable. After the meter is replaced, the meter cannot be rotated at will, which can effectively prevent electricity theft and leakage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, a simple device for quickly replacing an electric energy meter without power outage comprises an insulating base 1, an insulating fixing base 2, an insulating rotating cover 3, an insulating cover plate 4, a copper pin connector 5, a locking bolt pin 6 and a metal spring 7;

[0033] The insulating base 1 is an integrally formed injection molded part, and the insulating base 1 comprises a back plate 11, an ear plate 12 symmetrically arranged at the lower front side of the back plate 11, and a support plate 13 fixedly connected to the bottom of the front side of the back plate 11;

[0034] The insulating fixing seat 2 is connected to the support plate 13 by a buckle, and the insulating fixing seat 2 is also fixed to the insulating base 1 by a slide groove, and the upper rear side of the insulating fixing seat 2 is arc-shaped;

[0035] The insulating rotating cover 3 is buckled on the insulating fixed seat 2, and the inner walls of the front and rear side plates of the insulating rotating cover 3 are rotatably connected to the insulating fixed seat 2 through the rotating head 31, and an arc-shaped cover plate is provided at the lower rear side of the insulating rotating cover 3;

[0036] The insulating cover plate 4 is rotatably connected to the long hole arranged on the front side of the insulating rotating cover 3 through a rotating shaft;

[0037] The copper pin connector 5 and the bolt pin 6 are both cylindrical cavity structures. The front end of the copper pin connector 5 is in a four-petal cylindrical shape, and the rear end is in a door-shaped structure. The copper pin connector 5 is fixedly connected to the top plate of the insulating rotating cover 3 and is evenly provided with a plurality of bolt pins 6 along the length direction of the insulating rotating cover 3. The bolt pin 6 is made of metal, and the front end of the bolt pin 6 is lantern-shaped and the rear end is cylindrical. The top end of the bolt pin 6 is aligned and inserted into the inner cavity of the copper pin connector 5;

[0038] The metal spring 7 is fixed in the insulating fixing seat 2 and is arranged corresponding to the lock tongue needle 6. The head of the metal spring 7 extends out of the insulating fixing seat 2. When the insulating rotating cover 3 is in a vertical state, the metal spring 7 is inserted into the door-type structure of the corresponding copper pin connector 5 and squeezes the lock tongue needle 6. When the insulating rotating cover 3 is rotated out, the metal spring 7 pulls out the door-type structure of the corresponding copper pin connector 5 and cancels the squeezing of the lock tongue needle 6.

[0039] Preferably, the upper parts of the copper needle connector 5 and the lock tongue needle 6 are provided with slots. Through the setting of the slots, when subjected to external compression, the upper part of the copper needle connector 5 forms petal-shaped fins and the upper part of the lock tongue needle 6 can form lantern-shaped fins. Each lock tongue needle 6 corresponds to a group of metal spring leaves 7, and each group of metal spring leaves 7 has a tendency to expand outward.

[0040] When the insulating rotary cover 3 is in a vertical position, the metal spring sheet 7 axially presses the bolt needle 6, so that the upper portion of the bolt needle 6 forms a lantern-shaped fin and the upper portion of the copper needle connector 5 forms a petal-shaped fin.

[0041] Preferably, a metal terminal 8 is fixedly connected inside the insulating fixing seat 2 , and the metal terminal 8 is sleeved on the outside of each group of metal spring leaves 7 .

[0042] Preferably, a metal shorting piece 9 corresponding to each group of metal spring leaves 7 is fixedly connected to the rear side of the insulating rotating cover 3 .

[0043] Preferably, the integral structure of the insulating rotating cover 3 and the insulating cover plate 4 is symmetrically fixed with a limiting axis 10 on both sides, and a limiting groove 101 corresponding to the limiting axis 10 is opened on the ear plate 12, and the limiting groove 101 includes a vertical positioning portion 1011 and a sliding portion 1012 with an inclined bottom surface.

[0044] Preferably, a space-avoiding groove 14 is formed on the back plate 11 .

[0045] Preferably, the insulating base 1, the insulating fixing seat 2, the insulating rotating cover 3 and the insulating cover plate 4 are all made of hard plastic injection molding.

[0046] A specific embodiment of the present invention is:

[0047] When the device is installed, the metal spring sheet 7 is connected to the wire through screws to conduct electricity.

[0048] Figure 6 This is a schematic diagram of the normal use of the device. The socket at the tail of the electric energy meter is plugged into the corresponding copper pin connector 5, and the integrated structure of the electric energy meter, the insulating rotating cover 3 and the insulating cover plate 4 is rotated to a vertical state. The electric energy meter is positioned by the ear plate 12. At this time, the top of each group of metal springs 7 extends into the copper pin connector 5. Since each group of metal springs 7 has a tendency to expand outward, the tension of the metal springs 7 enables a reliable connection with the door-type structure of the copper pin connector 5. Since each group of metal springs 7 axially squeezes the lock tongue needle 6, the fins of the lock tongue needle 6 expand. When the fins of the lock tongue itself expand, the fins of the copper pin connector 5 are driven to expand, thereby increasing the friction between the socket at the tail of the electric energy meter and the fins of the copper pin connector 5, and increasing the contact area between the copper pin connector 5 and the socket at the tail of the electric energy meter, thereby achieving a large current conduction capability.

[0049] After the electricity meter is installed, all metal conductors are built into the insulating casing, which can effectively prevent electricity theft.

[0050] Figure 7This is a schematic diagram of replacing an electric energy meter in the device. First, open the insulating cover 4. At this time, the limit shaft 10 slides out through the sliding portion 1012, and then the integrated structure of the electric energy meter, the insulating rotating cover 3 and the insulating cover 4 is flipped outward. At this time, the metal shorting piece 9 rotates synchronously with the insulating rotating cover 3. When the metal shorting piece 9 moves to the position corresponding to the metal spring piece 7, the metal shorting piece 9 is inserted into the corresponding metal spring pieces 7 on both sides, so that the electric energy meter can be replaced without power outage. At this time, the metal spring piece 7 is separated from the lock tongue needle 6. When the lock tongue needle 6 contracts, the copper needle connector 5 contracts accordingly, so that the friction between the copper needle connector 5 and the rear jack of the electric energy meter becomes smaller, making it convenient to pull out the electric energy meter.

[0051] At this time, since the integrated structure of the copper pin connector 5 and the bolt pin 6 is separated from the metal spring 7, the copper pin connector 5 is not charged, thereby avoiding electric shock during the replacement of the electric energy meter.

[0052] After the socket at the tail of the energy meter is connected to the copper pin connector 5, the integrated structure of the energy meter, the insulating rotating cover 3 and the insulating cover plate 4 is rotated to a vertical state. At this time, the limit shaft 10 enters the positioning part 1011, which can prevent the energy meter from flipping over at will and prevent the metal terminal 8 from being exposed.

[0053] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
