Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to a photovoltaic connector connected to a PCB board. Background Art
[0002] Conventional photovoltaic connector terminals and PCBs often use crimping and screws to connect. While crimping can achieve a connection, it's relatively unreliable and can easily heat up at the crimping point, leading to excessive resistance and fire hazards. Furthermore, the need for wire assembly not only occupies more space within the chassis but also increases component processing steps, which can easily lead to contact failure and increase overall machine costs. To address this issue, we propose a photovoltaic connector for PCB connections that addresses these issues. Utility Model Content
[0003] The purpose of the present invention is to provide a photovoltaic connector connected to a PCB board to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a photovoltaic connector connected to a PCB board, comprising an assembly housing, a first terminal housing and a second terminal housing arranged in the assembly housing, and a first connecting terminal and a second connecting terminal welded on the PCB board, the first terminal housing and the second terminal housing are socketed with the assembly housing, the first connecting terminal is connected to the first terminal at one end away from the PCB board, the second connecting terminal is connected to the second terminal at one end away from the PCB board, the first connecting terminal and the first terminal are arranged in the first terminal housing, the second connecting terminal and the second terminal are arranged in the second terminal housing, and a stretchable member is connected between the first connecting terminal and the first terminal, the second connecting terminal and the second terminal. When the first terminal housing or the second terminal housing is pulled, the stretchable member causes the first terminal housing or the second terminal housing to move on the assembly housing.
[0005] Preferably, the stretchable member is a soft braided wire.
[0006] Preferably, it further comprises plugs respectively engaged with the first terminal housing and the second terminal housing, and the first connecting terminal and the second connecting terminal are respectively connected with the first terminal housing and the second terminal housing by being engaged with the plugs.
[0007] Preferably, waterproof rings are provided between the assembly housing and the first terminal housing and the second terminal housing respectively.
[0008] Preferably, nuts are provided between the assembly housing and the first terminal housing and the second terminal housing respectively.
[0009] Preferably, the first terminal housing and the second terminal housing are arranged in parallel.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The copper braided cable structure eliminates the need for screw assembly after crimping, reducing production steps and conserving space. Furthermore, the integrated, directly connected soft braided cable structure is more stable and less susceptible to overheating, improving the overall stability of the terminal connection. The soft braided cable is riveted to the terminal, providing excellent flexibility. During assembly, the soft braided cable can float freely to a certain length, enabling a better and more flexible connection between the terminal housing and the assembly housing.
