[0002] Inner support fixtures of junction boxes are usually used to support electric wires or cables to avoid being affected by pressure or tension. The inner support fixtures are made of metal materials and usually have elasticity, and can adjust the tension of electric wires or cables to a certain extent. These inner support fixtures are usually fixed inside the junction box and are abutted against the inlet of the junction box, which can prevent the loosening or disconnection of electric wires or cables at the connection points. Using these inner support fixtures can ensure the reliable connection of electric wires or cables, thus ensuring the normal operation of the circuit.

[0003] However, during the clamping process of the existing inner support fixture on the surface of the cable with an elastic metal sheet, the insulation layer on the surface of the cable is easily damaged, affecting the surface protection effect of the cable. Moreover, this abutting and clamping method is cumbersome to disassemble and assemble, and the operations of maintaining and replacing the cable are troublesome. In view of this, research and improvement are carried out on the existing problems, and an inner support fixture for a photovoltaic junction box is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.
