Embodiment approach 1

[0020] Such as Figure 1 to Figure 3 The shown filter connection terminal, the filter screw connection terminal, includes a shaft core, and the shaft core is respectively an internal wiring section 1, a fixed section 2 and an external wiring section 4 from left to right, and the internal wiring section and the filter The internal components are connected, the fixed section is connected with the filter shell, so that the connecting terminal is fixedly connected to the filter shell, and the external wiring section is used to connect with the external copper bar. The fixed section 2 and the external wiring section 4 There are polygonal connectors 3 fixedly connected therebetween. In the present embodiment, the number of sides of the polygonal connectors is 6, and the right side of the polygonal connectors 3 is a smooth plane, and the right side of the polygonal connectors is connected to the circumscribed Copper bar connection, the right side is a plane that increases the contact...

Embodiment approach 2

[0024] The basic structure of this embodiment is the same as that of Embodiment 1. In Embodiment 2, the number of sides of the polygonal connector is four, and the use of a quadrilateral is convenient for processing. However, compared with the standard hexagonal shape, it may be inconvenient to connect with a wrench. .

[0025] The invention overcomes the defect of small effective contact area of ​​the traditional nut connection by integrating the polygonal connector connected with the external copper bar, increases the conductive area of ​​the connecting terminal, and increases the current allowed to flow through the connecting terminal. At the same time, the design of the polygonal connector is adopted, so that when installing the copper bar, the polygonal connector can be clamped by a wrench to prevent the connecting terminal from rotating, which facilitates the installation of the copper bar and improves the convenience of copper bar installation.

[0026] To sum up, the p...

Abstract

The invention belongs to the field of fittings of a photovoltaic EMC (Electro Magnetic Compatibility) filter, in particular to a filter screw bolt connection terminal with large conductive contact area. The filter screw bolt connection terminal comprises a shaft core, and is characterized in that the shaft core comprises an internal connection section, a fixing section and an external connection section respectively from left to right; a polygonal connecting piece is fixedly connected between the fixing section and the external connection section; the right side surface of the polygonal connecting piece is an even plane surface; the fixing section comprises a threaded section and a smooth section; the smooth section is connected with the polygonal connecting piece; and screw threads are formed on the surface of the external connection section. The filter screw bolt connection terminal achieves large conductive contact area, can effectively reduce the resistance and the operation temperature rise of a contact conductor, can effectively avoid the electrochemical reaction on the connection terminal, and can overcome the problem of bad contact between the connection terminal and a copper bar.

Description

technical field [0001] The invention belongs to the field of photovoltaic EMC filter accessories, in particular to a filter screw connection terminal with a large conductive contact area. Background technique [0002] The traditional filter connection terminal uses double nuts to fix the external copper bar. The contact area between the copper bar and the nut is large, but the nut and the connection terminal are connected by threads, the actual effective conductive contact area is small, and its resistance Large, resulting in a faster temperature rise of the connecting terminal, the connecting terminal is prone to electrochemical reactions at the connection, producing oxides, resulting in poor contact between the connecting terminal and the external copper bar, affecting the normal operation of the filter. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention designs a large conductive contact area, which can effectively...
