There is no limit to creativity, and the instrument is invented. Today we introduce a national invention patent, a single-phase energy meter connector and how to use it. The patent was filed by Ningbo Quansheng Shell Co., Ltd. and was authorized to be announced on March 1, 2017.
Description
The invention belongs to the field of single-phase electric energy meters, in particular to a single-phase electric energy meter connector and a using method thereof.
Background of the invention
With the upgrading and upgrading of the power grid, the use of single-phase electric energy meters is more and more extensive. However, the current energy meter and circuit breaker isolating switch is installed by means of wiring. Because the manual screw is used, the on-site installation and construction workload is caused. Large, it is easy to appear wrong, missed, resulting in safety hazards, but also increase the cost of operation, it is necessary to design a more convenient and safe wiring device to replace the original wiring device.
Summary of the invention
The technical problem to be solved by the present invention is to provide a single-phase electric energy meter connector and a using method thereof, so as to solve the problem that the original wiring device is too complicated and the wiring is inconvenient.
The technical solution adopted by the technical problem of the present invention is to provide a single-phase electric energy meter connector, which comprises a watch tray, and the watch tray is connected with a single-phase electric energy meter through a sliding guide groove structure, and the main body of the watch tray is a flat plate. The three edges adjacent to one side of the main body extend upwardly to form three frame structures, and a plurality of side-by-side mounting holes are formed in the bottom plate of the frame structure; The lower half of the connector seat is matched with the card slot on both sides of the plug limiting block by the positioning slot, so that a plurality of semicircular structures arranged side by side of the plug limiting block cooperate with a plurality of semicircular structures of the plug socket to form a plurality of circles. The position of the hole and the hole is corresponding to the position of the mounting hole; the probe hole passing through the connector is limited to the upper side of the mounting hole on the bottom plate; the mounting hole and the hole are positioned inside, and the plug is installed.
The plug is in the shape of a column, and the plug is a plug head, a lantern shrapnel mounting portion, a plug body and a resistance welding platform from the beginning to the end, and a plug limiting ring is arranged in the middle of the plug body, the resistor The welding platform is semi-cylindrical, the diameter of the lantern shrapnel mounting groove is smaller than the diameter of the plug body and the plug head, the diameter of the plug limiting ring is larger than the diameter of the plug main body, and the lantern flower shrapnel mounting groove is covered with a lantern shrapnel. .
The lantern shrapnel is a hollow cylinder, and the outer surface of the hollow cylinder has a twill weft shape and expands outward in the middle of the cylinder to form an arc. The plug has a semi-cylindrical shape, and the plug comprises a plug body and a plug limiting ring. The plug body is a conductive platform, an anti-rotation platform and a resistance welding platform from the beginning to the end, and the anti-rotation platform is formed on a semi-cylindrical plane to form a plug. The plane boss has a plug limit ring on the anti-rotation platform, and the arc radius of the plug limit ring is larger than the arc radius of the anti-rotation platform.
The inside of the bottom plate of the frame structure is fixed to the plug seat by screws on the four corners. The probe is fixed at a corner of the upper portion of the bottom plate.
A method for using a single-phase electric energy meter connector, comprising: 1) welding a resistance welding platform of a plug with a resistance welding machine, and an outer diameter of the solder joint is smaller than an outer diameter of the plug body; 2) a plug and a base The mounting hole position is kept in the coaxial position; 3) inserting the plug limit block under the plug seat, so that the plug is limited in both the radial direction and the axial direction; 4) the wire is sequentially passed from the inner side of the bottom plate of the frame structure through the mounting hole position Push into the bottom plate; 5) screw the bottom plate and the plug base; 6) judge whether there is a lantern flower spring mounting groove on the plug, if there is the lantern flower spring mounting groove, put on the lantern flower shrapnel; 7) the single phase The electric energy meter is inserted into the single-phase electric energy meter connector along the sliding guide structure on the watch tray to complete the installation.
The invention replaces the original wiring mode by using the plugging and unplugging wiring mode, can effectively avoid the situation of misconnection and leakage, and reduces the workload of on-site construction and installation. The entry line of the utility model is a closed frame structure, which makes the incoming connection part more secure. The utility model is positioned by the cooperation of the lantern shrapnel, the mounting hole position and the round hole, so that the single-phase electric energy meter has a certain insertion and extraction strength. The lantern is made of beryllium copper material and heat treated, and the surface is silver plated. The plug material has high elasticity and abrasion resistance when the interference fit is effectively solved. Each type of plug realizes the interference fit or (insertion) clearance fit of the corresponding energy meter jack within the tolerance range (±0.1 mm), which effectively solves the stability of the long-term power-on temperature rise limit of the lantern connection part.
