Description

Technical Field

[0001] The utility model belongs to the technical field of intensive busbars, in particular to a wire end connection structure of a intensive busbar. Background Art

[0002] The dense busbar is a power transmission device widely used in the industrial field. By integrating multiple wires on a trunk, it effectively transmits electric energy to various terminal devices, greatly simplifying the wiring and maintenance of the power transmission system. The structure of the dense busbar is usually made of copper or aluminum, with very high conductivity, which can reduce voltage drop and power loss, improve the efficiency of the system, can be flexibly assembled and installed, reduce failure rate and maintenance cost, have small resistance, inductance and capacitance characteristics, reduce electromagnetic interference, and is widely used in various industrial fields to meet the requirements of large current transmission, long-distance transmission and high reliability. When the dense busbar is installed, it is usually necessary to use a connection structure to connect the wire ends of the dense busbar to ensure the stability of the dense busbar connection during use, but it still has the following disadvantages in actual use:

[0003] 1. When connecting the wire ends of dense busbars, since the two wire ends are not directly connected, the resistance at the wire ends is often greater when the current is transmitted, and it is easier to generate heat. Long-term exposure to high temperature may cause damage to the connection structure or even the dense busbars;

[0004] 2. When actually connecting dense busbars, the length of the busbar ends is often not just suitable for the installation of the connection structure. There may be a certain distance between the two ends, making the installation inconvenient. Utility Model Content

[0005] The utility model aims to provide a wire end connection structure for a dense busbar, which solves the problem that, when the wire end connection structure for the dense busbar is actually used, the resistance at the wire end connection is higher than that at other positions, more heat is generated, the connection structure is prone to overheating and damage for a long time, and the length of the wire end of the dense busbar is often not suitable for the installation of the connection structure when it is installed, through a connecting frame and a top cover.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a line head connection structure of a dense busbar, comprising a connection frame and a top cover, wherein the two ends of the connection frame are clamped and fixed with limited airbags, a plurality of positioning airbags are clamped and fixed in the connection frame, a plurality of elastic heat-conducting plates are clamped through the connection frame, a conductive plate is clamped on one side of each of the elastic heat-conducting plates, the top of the connection frame is rotatably clamped with the top cover, and a plurality of the elastic heat-conducting plates are all penetrated and plugged into the bottom of the top cover;

[0008] The two dense busbars can be limited by the limiting airbag to ensure the stability of the connection between the connecting structure and the two dense busbar shells. After the dense busbar wire ends are plugged into the inner side of the connecting frame, the positioning airbag can be inflated to expand and squeezed on one side of the wire end, so that the wire end is squeezed and positioned between the elastic heat conductive plate and the positioning airbag to ensure the stability of the wire end connection. The wire end can be heat-conducted by the elastic heat conductive plate, and the heat dissipation area is increased by the elastic heat conductive plate that is connected to the outside and has a large heat conductive area, and the wire end is further dissipated without causing pollution to the connecting frame, avoiding rust on the dense busbar wire ends, and extending the service life of the connecting structure and the dense busbar. At the same time, the wire ends of the two dense busbars only need to be fitted with the conductive plate. When the current is transmitted through one dense busbar, when it reaches the wire end of the busbar, the current can be transmitted to the wire end of another dense busbar through the conductive plate, so that the two wire ends do not need to be fitted, thereby improving the convenience and flexibility of installation.

[0009] Furthermore, a plurality of the positioning airbags and a plurality of elastic heat-conducting plates are alternately arranged in the connecting frame, a plurality of insulating baffles are clamped and fixed in the connecting frame, and one of the insulating baffles is clamped between an adjacent elastic heat-conducting plate and a positioning airbag;

[0010] After the wire ends of the dense busbars are placed between the elastic heat conductive plate and the positioning airbag, the positioning airbag is inflated to expand and squeeze the wire ends, so that the wire ends are squeezed and positioned between the elastic heat conductive plate and the positioning airbag to ensure the stability of the wire end connection.

[0011] Furthermore, an air pump is inserted through one side of the connecting frame, one end of the air pump is inserted through one side of the limiting airbag, and the two limiting airbags are connected to the multiple positioning airbags;

[0012] The air pump can be used to inflate the limiting airbag and the positioning airbag, so that the limiting airbag expands and positions one end of the dense busbar, thereby ensuring the stability of the connection structure and the connection between the two dense busbar shells.

[0013] Furthermore, a plurality of heat dissipation holes are formed through the top of each of the elastic heat-conducting plates, one end of the two limiting airbags is clamped and fixed to the bottom of the top cover, and the plurality of elastic heat-conducting plates, the positioning airbags and the insulating partition are located between the two limiting airbags;

[0014] The wire ends can be heat-conducted through the elastic heat-conducting plate, and the heat dissipation area is increased by the elastic heat-conducting plate that is connected to the outside and has a large heat-conducting area, so as to further dissipate the heat of the wire ends without causing pollution to the connecting frame, avoiding rust of the dense busbar wire ends, and extending the service life of the connecting structure and the dense busbar.

[0015] Furthermore, a photovoltaic panel is fixedly connected to the top of the top cover, and a ventilation groove is formed through one end of the top cover, and the ventilation groove is connected through the heat dissipation hole;

[0016] Photovoltaic panels can convert solar energy into electrical energy for use in air pumps. When the dense busbar and connecting structure are in use, when the air pressure in the positioning airbag and the limiting airbag drops to a threshold, the air pump can be controlled to inflate the positioning airbag and the limiting airbag again, further ensuring the stability of the connecting structure during use.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that when the wire end connection structure connects the wire ends of the dense busbar, since the two wire ends are not directly connected, the resistance at the wire ends is often larger when the current is transmitted, and it is easier to generate heat. Long-term exposure to high temperature may cause damage to the connection structure and even the dense busbar. After the wire ends of the dense busbar are placed on the inner side of the connecting frame, the limiting airbag and the positioning airbag are inflated by an air pump to expand the positioning airbag and squeeze it on one side of the wire end, so that the wire end is stably connected between the positioning airbag and the elastic heat conductive plate. When the line transmits current and generates a lot of heat at the wire ends and the connection structure, the wire ends are heat-conducted by the elastic heat conductive plate, and the heat dissipation area of ​​the elastic heat conductive plate is greatly increased through the heat dissipation holes, so as to cool the connection structure and the wire ends and extend the service life of the dense busbar and the connection structure.

[0019] 2. The utility model solves the problem that when the busbar is actually connected, the length of the busbar wire ends is often not just suitable for the installation of the connection structure, and there may be a certain distance between the two wire ends, resulting in inconvenient installation by setting a connecting frame. When installing and connecting the wire ends, it is only necessary to use the positioning airbag to make the wire ends of the dense busbar close to the conductive plate. When the current is transmitted through a dense busbar, when it reaches the wire end of the busbar, the current can be transmitted to the wire end of another dense busbar through the conductive plate, so that the two wire ends do not need to be fitted together, thereby improving the convenience and flexibility of installation.
