Technical Field
[0001] This utility model relates to the field of electricity meter wiring technology, specifically to a laminated busbar. Background Technology
[0002] The meter box is a special box for installing electricity meters and related electrical equipment. It is a key node for electricity settlement and metering between the power system and users. Currently, the electricity meters and protective switches inside the meter box are connected by wires. This wiring method has the following problems: (1) Power workers need to spend a lot of time and effort to do the wiring, and there are wiring errors, such as reverse connection of neutral and live wires or incorrect wiring of incoming and outgoing lines; (2) A large number of electrical connections inside the meter box are connected by wires and terminals. Over time, the terminal gaskets and screws are prone to loosening or corrosion, which can cause increased contact resistance and local overheating, posing a potential safety hazard.
[0003] In view of this, there is an urgent need to design a more reasonable and reliable wiring structure to solve the current electrical wiring problems of electricity meters. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a laminated busbar, comprising a laminated plate body, the laminated plate body including at least one embedded layer, with insulating layers on both sides of the embedded layer, and a meter mounting position on the surface of the laminated plate body; at least one busbar wiring unit is connected to the laminated plate body, the busbar wiring unit including a live wire inlet busbar, a live wire outlet busbar, a neutral wire inlet busbar, and a neutral wire outlet busbar; both the live wire inlet busbar and the neutral wire inlet busbar include an inlet body portion, with a meter inlet connection terminal and a power supply side connection terminal respectively at both ends of the inlet body portion; both the live wire outlet busbar and the neutral wire outlet busbar include an outlet body portion, with a meter outlet connection terminal and a load side connection terminal respectively at both ends of the outlet body portion; both the inlet body portion and the outlet body portion are connected within the embedded layer, and both the meter inlet connection terminal and the meter outlet connection terminal protrude from the laminated plate body and face the meter mounting position.
[0005] In one possible implementation, the embedded layer is provided with positioning grooves, and the positioning grooves on each of the embedded layers are independent of each other, with the incoming main body and the outgoing main body respectively connected to the positioning grooves.
[0006] In one possible implementation, the meter inlet connection and the meter outlet connection of the same busbar wiring unit are oriented in the same direction and located on the same mounting plane.
[0007] In one possible implementation, the power supply side connection terminals of the same busbar wiring unit are oriented in the same direction and located on the same mounting plane, and the load side connection terminals of the same busbar wiring unit are oriented in the same direction and located on the same mounting plane.
[0008] In one possible implementation, if at least two busbar connection units are provided; all the busbar connection units share the same neutral wire incoming busbar, the neutral wire incoming busbar including a power supply side connection terminal and several meter incoming connection terminals.
[0009] In one possible implementation, both the live wire outgoing busbar and the neutral wire outgoing busbar include only one meter outgoing connection terminal and one load-side connection terminal.
[0010] In one possible implementation, the meter inlet connection terminal and the meter outlet connection terminal are provided with meter connection holes.
[0011] In one possible implementation, the insulating layer is a PET insulating film.
[0012] In one possible implementation, the meter mounting position has a meter mounting hole.
[0013] In one possible implementation, the laminated plate body has a body fixing hole.
[0014] The method of using the stacked busbar in this technical solution is as follows: First, install the stacked busbar in the meter box, connect the power supply side disconnect switch to the power supply side connection terminal, connect the load side disconnect switch to the load side connection terminal, connect the energy meter or energy meter connector to the meter mounting position and connect it to the meter inlet connection terminal and the meter outlet connection terminal, thus completing the installation of the main electrical equipment in the meter box.
[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages: In this technical solution, each connection end of the laminated busbar is pre-designed and fixed, which physically prevents human errors such as reverse connection of live and neutral wires or reverse connection of incoming and outgoing lines, ensuring the accuracy of wiring from the source. Furthermore, the use of integrated busbar conductors to replace a large number of wire crimp terminals fundamentally eliminates the problem of increased contact resistance caused by loose screws, insufficient contact pressure, or corrosion, thereby effectively avoiding the risk of local overheating or even fire. The insulation layers on both sides of the embedded layer safely isolate and encapsulate all the busbars together, making the overall insulation performance and protection level of the laminated busbar better than the outside.
[0016] This technical solution uses a stacked busbar to simplify complex wiring work that requires specialized skills into a simple alignment connection. Electrical workers only need to align and fix devices such as switches and meters to the corresponding connection terminals, significantly shortening installation time and reducing reliance on skilled operators. At the same time, the stacked busbar integrates the originally messy wiring network into a simple and standardized pre-embedded terminal block, making the internal layout of the meter box clear and aesthetically pleasing, greatly facilitating later inspections and maintenance. Furthermore, the stacked design allows for the layout of meter circuits within a limited space, saving internal space in the meter box and making it possible to achieve a more compact box design.

[0045] This technical solution uses a stacked busbar to simplify complex wiring work that requires specialized skills into a simple alignment connection. Electrical workers only need to align and fix devices such as switches and meters to the corresponding connection terminals, significantly shortening installation time and reducing reliance on skilled operators.
