[0031] In this embodiment, the quick wiring device is specifically used to electrically connect the combined metering box to the external circuit. The quick wiring device of this embodiment includes a socket module constructed on the combined metering box and a plug module connected to the external circuit. The socket module includes a plurality of voltage terminals 11 constructed on the outer wall of the combined metering box and a plurality of current terminals 12. The socket module includes a columnar main body 21, voltage jacks 211 constructed on the columnar main body 21 and corresponding to and inserted into the plurality of voltage terminals 11 one by one, and current jacks 212 constructed on the columnar main body 21 and corresponding to and inserted into the plurality of current terminals 12 one by one.

[0032] The purpose of the quick wiring device for the combined metering box in this embodiment is to insert the plug module of the quick wiring device for the combined metering box into the socket module after unifying the sizes of the wiring terminals and the interface standards, so as to solve the problems of inconvenient on-site wiring and easy wiring errors.

[0033] The purpose of this device is achieved as follows: First, the interface specifications are unified, and the unified wiring terminal sizes and interface standards for the manufacturers are formulated to ensure the compatibility of equipment from different manufacturers. Second, the quick wiring device for the combined metering box adopts a plug-in method. When connecting, the plug module of the device is inserted into the socket module of the combined metering box according to the corresponding positions of the concave and convex grooves.

[0034] This device has a simple structure and is convenient to operate. It safely and efficiently solves the problems of inconvenient on-site wiring and easy wiring errors of the combined metering box, and at the same time improves the work efficiency.

[0035] The present invention discloses a quick wiring device and a combined metering box. The device includes a socket module and a plug module. The socket module integrates voltage terminals and current terminals and is correspondingly plugged with the plug module through the jacks on the columnar main body, solving the problems of low wiring efficiency and easy errors caused by different sizes and chaotic arrangements of the wiring terminals of the traditional combined metering box, and realizing fast and accurate circuit connection.

[0036] This device can shorten the single wiring time on the pole from 30 minutes to 3 minutes, and reduce the error rate to less than 0.5%.

[0037] The material of the columnar main body is insulating engineering plastic. The size range of the diameter of the columnar main body can be 30mm ± 2mm, or other values, which can be specifically selected according to needs.

[0038] In some embodiments, the socket module further includes an annular enclosure 13 constructed on the outer wall of the combined metering box. A plurality of voltage terminals 11 and a plurality of the current terminals 12 are both located within the annular enclosure 13, and the columnar main body 21 passes through the annular enclosure 13.

[0039] In this embodiment, the socket module further includes an annular enclosure 13 constructed on the outer wall of the combined metering box. A plurality of voltage terminals 11 and a plurality of current terminals 12 are both located within the annular enclosure 13, and the columnar main body 21 passes through the annular enclosure 13. On the one hand, the annular enclosure 13 can protect the voltage terminals 11 and the plurality of current terminals 12. On the other hand, during the plug-in installation, the annular enclosure 13 and the columnar main body 21 cooperate for plug-in guiding, so that the plug module can be quickly inserted onto the socket module. This structure is simple, convenient to operate, safely and efficiently solves the problems of inconvenient wiring on the pole of the combined metering box, easy wiring errors, and reduction of safety risks, and at the same time improves the work efficiency.

[0040] In some embodiments, a locking structure is provided between the annular enclosure plate 13 and the columnar body 21 to lock the two.

[0041] In this embodiment, a locking structure is provided between the annular enclosure 13 and the columnar body 21 to lock the two together, thereby preventing the plug module and the socket module from being separated, ensuring the reliability of the connection between the two and ensuring the smooth flow of the line.

[0042] In some embodiments, the locking structure includes a locking sleeve 31 rotatably disposed on the columnar body 21, and the annular enclosure plate 13 is at least partially located in the locking sleeve 31;

[0043] The inner hole wall of the locking sleeve 31 is configured with an internal thread, and the outer wall of the annular enclosure plate 13 is configured with an external thread matching the internal thread.

[0044] In this embodiment, the locking sleeve 31 is rotatably set on the columnar body 21. Since the inner hole wall of the locking sleeve 31 is configured with an internal thread, and the outer wall of the annular enclosure 13 is configured with an external thread adapted to the internal thread, when the locking sleeve 31 is rotated, the locking sleeve 31 and the annular enclosure 13 can be threadedly locked, thereby realizing the locking between the annular enclosure 13 and the columnar body 21. The structure is simple, the operation is convenient, and the assembly efficiency is improved.

[0045] In some embodiments, an annular shoulder 213 is configured on the outer periphery of the columnar body 21 , and the annular shoulder 213 abuts against the annular enclosure plate 13 .

[0046] In this embodiment, the annular shoulder 213 is in contact with the annular enclosure 13 to prevent the columnar body 21 from axially shaking on the annular shoulder 213 and causing poor contact.

[0047] In some embodiments, the locking sleeve 31 is sleeved on the annular shoulder 213, and an annular retaining ring 311 is constructed at an end portion of the locking sleeve 31 away from the annular enclosure 13.

[0048] In this embodiment, the locking sleeve 31 is sleeved on the annular shoulder 213, and an annular retaining ring 311 is constructed on an end portion of the locking sleeve 31 away from the annular enclosure 13. Since the annular retaining ring 311 is located on the side of the annular shoulder 213 away from the annular enclosure 13, and the inner diameter of the annular retaining ring 311 is smaller than the outer diameter of the annular shoulder 213, when the locking sleeve 31 is threadedly locked with the annular enclosure 13, the annular retaining ring 311 can limit each other with the annular shoulder 213, thereby ensuring that the locking sleeve 31 and the annular enclosure 13 are enclosed together.

[0049] In some embodiments, a first protrusion 131 is provided on the annular shroud 13, a first through hole 1311 is provided on the first protrusion 131, a second protrusion 312 is provided on the locking sleeve 31, and a second through hole 3121 is provided on the second protrusion 312. The quick wiring device further includes a lead seal wire harness, and the lead seal wire harness is passed through the first through hole 1311 and the second through hole 3121 so that the locking sleeve 31 and the annular shroud 13 are both lead-sealed.

[0050] In this embodiment, by passing the lead seal wire harness through the first through hole 1311 and the second through hole 3121, the locking sleeve 31 and the annular shroud 13 can be lead-sealed. The threaded locking sleeve is combined with the lead seal wire harness to ensure firm connection and anti-tampering. At the same time, it is convenient for the staff to find the displacement of the socket module and the plug module, and remind the staff to check for potential hazards in time.

[0051] The lead seal wire harness is made of weather-resistant nylon material. When installed, it needs to be passed through the first through hole and the second through hole and then pressed tightly to ensure that the locking sleeve cannot be disassembled by reverse rotation.

[0052] In some embodiments, a first limiting protrusion 214 is formed on the outer wall of the columnar body 21, and a first limiting groove 132 adapted to the first limiting protrusion 214 is formed on the inner wall of the annular shroud 13.

[0053] In this embodiment, through the cooperation of the first limiting protrusion 214 on the outer wall of the columnar body 21 and the first limiting groove 132 on the inner wall of the annular shroud 13, the problem of incorrect wiring is avoided, the problems of inconvenient on-site wiring and easy wiring errors of the combined metering box are solved, the incorrect insertion direction is eliminated, and the work efficiency is improved at the same time.

[0054] In some embodiments, a second limiting protrusion is formed on the inner wall of the annular shroud 13, and a second limiting groove adapted to the second limiting protrusion is formed on the outer wall of the columnar body 21.

[0055] In this embodiment, through the cooperation of the second limiting protrusion on the inner wall of the annular shroud 13 and the second limiting groove on the outer wall of the columnar body 21, the problem of incorrect wiring is avoided, the problems of inconvenient on-site wiring and easy wiring errors of the combined metering box are solved, the incorrect insertion direction is eliminated, and the work efficiency is improved at the same time.

[0056] In addition, the locking structure can also be a snap fastener, which may include a first half shell and a second half shell. Both the first half shell and the second half shell are semi-circular arc structures. One end of the first half shell and the second half shell is hinged. A bolt is rotatably provided at one end of the first half shell away from the second half shell. A locking plate extending radially outward is provided at one end of the second half shell away from the first half shell. A locking groove penetrating along the thickness direction is formed on the locking plate, and the locking groove extends to the side wall away from the second half shell to form an inlet for the bolt. A nut is provided on the bolt, and the snap fastener can be locked to the annular shroud 13 and the columnar body 21.

[0057] Furthermore, annular grooves extending circumferentially can be provided on the outer walls of both the annular shroud 13 and the columnar body 21, and annular protrusions adapted to the annular grooves of the annular shroud 13 and the annular grooves of the columnar body 21 are provided on the inner walls of the first half shell and the second half shell. This structure ensures the locking reliability of the snap fastener to the annular shroud 13 and the columnar body 21.

[0058] Of course, it is also possible to provide annular grooves on the inner walls of the first half shell and the second half shell, and annular protrusions on the outer walls of both the annular shroud 13 and the columnar body 21.

[0059] In the plug module of the quick wiring device of the combined metering box, wires of different colors are used to distinguish wiring terminals with different functions, and numbers are marked on the other side of the wire terminals, which is convenient for connecting external circuits, so as to achieve the purpose of convenient installation, avoiding wiring errors, and improving work efficiency.
