Description

Technical Field

[0001] This utility model relates to the field of connecting wires, specifically a solar panel connecting wire with a fixed structure. Background Technology

[0002] As an indispensable and important component of a solar power generation system, the solar panel connection cable is a bridge that enables power transmission and signal connection between the solar panel and other devices. It is usually made of a metal conductor with excellent conductivity as the inner core and covered with insulating and weather-resistant materials. These connection cables can stably transmit the DC power generated by the solar panel to the inverter, controller and other devices, ensuring the normal operation of the entire solar power generation system.

[0003] Currently, in the installation and application of solar panels, the solar panel connection wires are mainly connected to the solar panels using a snap-fit ​​structure. This snap-fit ​​structure is generally designed with a slot at a specific location on the solar panel, and the end of the connection wire is equipped with a matching clip. During installation, the clip is aligned with the slot and pressed in to complete the connection.

[0004] However, the snap-fit ​​connection structure also has some obvious defects. After long-term exposure to wind, sun, rain and large temperature changes, the snap-fit ​​structure is prone to aging and loosening, which reduces the stability of the connection between the connecting wire and the solar panel, causing the solar power generation system to fail to work properly. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a solar panel connection wire with a fixed structure to solve the technical problem that the snap-fit ​​connection components of the solar panel connection wire are prone to loosening after prolonged exposure to sunlight.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solar panel connecting wire with a fixed structure, including a solar panel, a connector fixed on one side of the solar panel, two sets of locking blocks installed inside the connector, a connecting wire movably installed inside the connector, an installer sleeved on the outer wall of the connecting wire, two sets of slots opened on the outer wall of the installer, and a protective sleeve sleeved on the outer wall of the installer.

[0007] By adopting the above technical solution, the problem of the snap-fit ​​connection assembly of the solar panel connection cable easily loosening after prolonged exposure to sunlight is solved. During the process of inserting the connection cable into the connector, the inner wall of the installer on the outer wall of the connection cable pushes the snap-fit ​​block into the connector. When the connection cable is fully inserted into the connector, the compressed spring pushes the snap-fit ​​block back to its original position, so that the connector is fixed by the snap-fit ​​installer. Then, the protective sleeve is put on and fixed to the outer wall of the installer. The groove of the protective sleeve is made of rubber, which has good sun resistance. The protective sleeve blocks sunlight and rain, preventing sunlight and rain from corroding the connector and the installer. The protective sleeve also squeezes and fixes the installer to prevent the connection cable from loosening inside the connector.

[0008] The present invention is further configured such that a spring is installed at one end of the card block, and the end of the spring is connected to the inner wall of the connector.

[0009] Preferably, during the insertion of the connecting wire into the connector, the inner wall of the mounter pushes the locking block into the connector, causing the locking block to compress the spring. When the connecting wire is fully inserted into the connector, the compressed spring pushes the locking block back to its original position, causing the locking block to engage in the slot inside the mounter.

[0010] The present invention is further configured such that sliders are installed on both sides of the card block, and a groove is provided inside the connector.

[0011] Preferably, when the card block moves into the connector, the connector controls the sliding state of the card block through a slider so that the card block does not tilt during the sliding process.

[0012] The present invention is further configured such that one side of the outer wall of the card block is inclined, and the outer wall of the card block is arc-shaped.

[0013] Preferably, during the insertion of the connecting wire into the connector, when the inner wall of the end of the mounter contacts the locking block, the mounter will press the locking block into the connector along the inclined wall of the locking block.

[0014] The present invention is further provided that the inner wall of the slot is fixed with an extrusion plate, and the extrusion plate has a certain elastic deformation capability.

[0015] Preferably, when it is necessary to remove the connecting wire from inside the connector, the pressing plate is pressed down, and the pressing plate pushes the clamping block into the inside of the connector, so that the installer can be removed from the outer wall of the connector.

[0016] The present invention is further configured such that a connecting ring is fitted on the outer wall of the connector, and the protective sleeve is threadedly connected to the connecting ring.

[0017] Preferably, the external thread on the outer wall of the connecting ring matches the internal thread on the inner wall of the protective sleeve, thereby facilitating the installation of the protective sleeve onto the connector.

[0018] The present invention is further provided that the outer wall of the solar panel is fitted with a fixing frame, and the fixing frame is made of stainless steel.

[0019] Preferably, a stainless steel mounting frame is used to protect and secure the solar panel, thereby reducing the risk of damage to the edges and corners of the solar panel from external objects.

[0020] The present invention is further configured such that two sets of fixing plates are sleeved on the outer wall of the connector, and the fixing plates are fixedly installed on the fixing frame by bolts.

[0021] Preferably, the fixing plate reinforces the connection between the connector and the solar panel to prevent the connector from falling off.

[0022] The present invention is further provided that a protective sleeve is fixed on one side of the installer, and the protective sleeve is made of rubber.

[0023] Preferably, the protective sleeve made of rubber has a certain degree of elasticity, and the protective sleeve can protect the connecting wire and reduce the damage to the internal structure of the connecting wire caused by excessive bending.

[0024] In summary, the present invention has the following main advantages:

[0025] This invention solves the problem of loosening of the snap-fit ​​connection assembly of the solar panel connection cable after prolonged exposure to sunlight by setting up a solar panel, connector, installer, locking block, spring, connecting wire, and protective sleeve. During the insertion of the connecting wire into the connector, the inner wall of the installer on the outer wall of the connecting wire pushes the locking block into the connector. When the connecting wire is fully inserted into the connector, the compressed spring pushes the locking block back to its original position, so that the connector is fixed by the locking block installer. Then, the protective sleeve is put on and fixed to the outer wall of the installer. The groove of the protective sleeve is made of rubber, which has good sun resistance. The protective sleeve blocks sunlight and rain, preventing sunlight and rain from corroding the connector and installer. The protective sleeve also squeezes and fixes the installer to prevent the connecting wire from loosening inside the connector.

[0026] This invention, by setting a limiting groove and a limiting block, ensures that when the installer is fitted onto the outer wall of the connector, the end of the limiting groove on the inner wall of the installer is horizontally aligned with the limiting block on the outer wall of the connector. Then, the installer is inserted into the outer wall of the connector. The limiting block controls the installation insertion angle of the installer, so that the slot inside the installer can be accurately fitted onto the locking block, avoiding the need for personnel to rotate and adjust the installer, and reducing the workload of personnel installing the connecting cable.
